Cats kept indoors can live a good life when they get access to a variety of positive experiences. Examples include performing natural behaviours, feeling safe at home and using their full sensory capabilities, including their sense of smell.

Plants such as catnip, cat thyme and silver vine are potent smelly stimulants that can affect cat minds and moods.

Ever wondered if these mind-altering substances are safe gifts for our feline friends? And importantly, is it OK to provide these, or is offering catnip to a cat like offering alcohol to a child?

Won’t my cat get bored if I keep it inside? Here’s how to ensure it’s happy

Catnip, cat thyme and silver vine, oh my!

Owners who are concerned about their cats feeling bored and frustrated might offer them fresh or dried catnip (Nepeta cataria), silver vine (Actinidia polygama), cat thyme (Teucrium marum) or other plant materials such as valerian (Valeriana officinalis) and Tatarian honeysuckle (Lonicera tatarica). These last couple could offer an alternative if your cat doesn’t respond to catnip.

Toys filled with the leaves or extracts of these plants can cause apparently euphoric behaviour in domestic cats (as well as big cats like leopards and jaguars). Not all cats respond this way to these smells, which is believed to have a genetic basis.

Are these treats safe for cats?

Cats have a highly developed sense of smell. Some plants release chemical compounds to deter insects or to attract predators of insects that might otherwise destroy them. This includes nepetalactone, an ingredient isolated from catnip and silver vine.

Indeed, it has been argued that exposure to nepetalactone leads to an increase in feel-good hormones in cats. It may also act as a natural mosquito repellent (note that it does not repel all mosquitoes and is not effective for flea or tick control).

This may be why sniffing catnip, silver vine and some other plants causes cats to roll on their backs and rub their chins, cheeks and bodies on the plants. Other observed behaviours include: licking, shaking their head while carrying plant material in their mouth, drooling, kicking the plant material with their hind feet, and a “wavelike” motion of the skin over their backs as muscles contract and relax.

These responses generally don’t last long, usually seconds to minutes, before cats relax or resume their normal behaviour.

Rather than becoming addicted to these substances, cats are more likely to become habituated and desensitised, with the plants having less effect over time. When sniffed, these plants appear to have no adverse effects on cats.

What actually is catnip and is it safe for my cat?

Is it ethical to alter the minds of our cats?

When considering how to improve the lives of animals we care for, we tend to focus on whether the benefits outweigh the potential harms.

Despite some marketing claims that these plants activates the brain’s opioid system, delivering a “natural high” for cats, there is no evidence these substances actually alter the minds of cats in the same way as alcohol or other drugs alter the minds of humans.

The marketing of these cat treats as “kitty crack” or “meowijuana” and silver vine sticks as “kitty cigarettes” is likely to deter some people from offering their cats this kind of olfactory stimulation.

Unlike offering alcohol to a child, though, the evidence suggests our cats are OK when given access to these treats. These items won’t induce psychosis and won’t lead to addiction or withdrawal symptoms. And we don’t need to worry about our cats operating heavy machinery or making important decisions under the influence of mind-altering substances!

Provided they can walk away at any time, it seems reasonable to let them opt in to a fun time.

In fact, we harness the power of cats’ sense of smell in other ways by using synthetic feline facial pheromones. This can help reduce fear, anxiety and distress in cats. These substances can come in useful in settings such as multi-cat households or when moving house.

Is it unethical to give your cat catnip?

How to make sure your cat has the purr-fect time

Offering a range of smells (olfactory stimulation) is just one way to ensure your cat has a varied and interesting life. Here are some tips:

• offer cats choices to interact with treats and toys – don’t force them

• rotate the toys and experiences on offer, so every day offers something fresh

• offer items that cats can scratch – scratching posts and corrugated cardboard are popular items

• if you are concerned your cat has swallowed part of a toy or seems unwell, check in with your vet.

Given the short-lived effects of these plant-based olfactory stimulants on cats, it is important that we optimise their environment, lifestyle and interactions with humans to improve their welfare. We can’t just rely on catnip or silver vine to give our cats a good life indoors – it’s really up to us!

Many of us remember vividly being yelled at or feeling threatened by a family member, a teacher, or a boss.

Terrifying experiences often get imprinted in our memory; remembering frightening events is essential to avoid them in future. It is a normal reaction that promotes our survival.

This strong connection between fear and memory may lead us to think fear can be an effective learning tool. Research shows, however, fear can have long-term negative consequences for children and adults alike – and can actually make it harder to learn in meaningful ways.

Here’s what the research says about how and what we learn when we are scared.

Stand back and avoid saying ‘be careful!’: how to help your child take risks at the park

How fear affects children’s learning

Fear is designed to protect us from current and future danger.

If children are faced with experiences that trigger fear, they learn to avoid new experiences – as opposed to exploring, engaging, and approaching the unknown with curiosity.

Consistent exposure to fear changes how the brain reacts to the outside world. Fear triggers a stress response in the brain and puts it in a state of alert; we become hyper ready to react swiftly and decisively to incoming threats.

This may be appropriate if, for example, you are confronted by an aggressive strangers. But such high levels of reactivity are not productive in learning environments like school, where we are asked to be open to new experiences and create innovative solutions.

In fact, the areas of the brain activated when we’re scared are different to those we use when thinking carefully how to address a tricky problem. Research has shown the more primitive parts of the brain take over the activity of the prefrontal cortex, the brain’s “control centre”, when we’re in a state of fear.

This means planning, making sound decisions and using our existing knowledge becomes very difficult if we feel threatened or afraid.

Children learn fear from the adults in their lives

Adults play a critical role in the healthy development of fear responses by modelling reactions to unknown situations. They also provide (or fail to provide) safe environments that promote children’s exploration.

Fear can be easily learned from significant adults. Studies have shown both toddlers and school-aged children learn to avoid new experiences if their parents communicate or show signs of fear in reference to them.

Think, for instance, about how a child can learn to fear animals by seeing how their parents react to them. Or, for example, the way constant warnings to “be careful!” may end up making a child too anxious to climb trees or take risks as they use play equipment.

Adult behaviours also affect the degree to which children feel safe to be themselves and explore the world with confidence.

Studies investigating the behaviours of parents have consistently shown harsh parenting (involving physical and verbal aggression) is related to poorer outcomes in children including academic underachievement, higher levels of aggression and anxiety and poor peer relationships.

The opposite is the case for parents who, while providing structure and reasons for boundaries, are warm and encourage autonomy.

Teachers also play a pivotal role in the development of fear responses. Students are more likely to be motivated and function well in classrooms if teachers are “autonomy-supportive”.

This means teachers:

• have a curious and open attitude towards students’ interests

• seek their perspective and offer choices

• invite their thoughts, and

• accept a range of emotions (from frustration, anger and reticence to playfulness, joy and curiosity).

How fear affects learning in adult life

Many people who experience anxiety in adulthood have been exposed in their childhood to environments where they have felt consistently threatened.

These adults may end up avoiding taking on new tasks, considering multiple viewpoints, and responding to questions. These are all skills employers usually value.

Work environments that induce fear can also be counterproductive and stressful.

Research suggests when employees perceive their work environments as unsafe, they are more likely to experience burnout, anxiety and stress. Stressful situations can also interfere with our ability to apply what we know flexibly to new situations.

On the flip side, researchers argue that a trusting relationship between employees and their managers can affect workers’ willingness to show vulnerability and take on tasks that involve uncertainty.

Researchers have also found positive relationships at work can encourage to creativity in the workplace, which makes work more interesting and enjoyable.

So, what do we learn when we are scared?

Yes, we learn from fear. The question is: what do we learn?

In response to threats and hostility, we learn to avoid challenge and comply with external rules (instead of wondering how systems can be improved). We protect our feelings and restrict our thoughts to what is safe.

Is this the kind of learning that allows us to grow and develop?

More than ever, children and adults are required to collaborate in creative ways to address difficult problems.

This means dealing with uncertainty and accepting that sometimes we make mistakes or fail.

That requires safe and nurturing environments – not home, school or work settings that are ruled by fear.

Arenicola, or lugworms, make some of the most beautiful structures on the beach. Little piles of wet sand are cast in a swirl from their rear end as part of their feeding cycle.

They are but one of an untold number of other participants in the constant evolution of forms at our water’s edge. Co-contributors include the wind, birds, rain, foliage, foot traffic and detritus, all shaping sand and associated debris into mini peaks and troughs, lines, blobs and tracks.

The forming of grains into what we commonly call a sandcastle on the other hand, speaks to a particularly human intentionality. Centred around the activity of building, these edifices rise and fall through a wild negotiation of the intent of a person and the intent of the materials they work with.

This dynamic and fickle nature of the granular shells, quartz, coral, glass and rock is perhaps its greatest appeal. Accrued since childhood, our knowledge of sand’s properties sits deep within our personal sculptural memory.

In collaboration with the beach

Building a sandcastle is a response to the full beach environment as a collaborator. We attune ourselves to the quality of the sand, marvel at the comings and goings of the water and orient our construction for the wind’s abrasive blast.

We are vigilant to dogs’ unintended mark making, and backward running ball catchers who involuntarily progress our work from castle to ruin. Moulds that reproduce their internal structure can be the age-old bucket, or the form can be loosened up using towels, sandals, buckets or a friend’s back … and perhaps said friend can be embedded in the structure if required.

We can include tunnels (that will sadly collapse) and moats and complete our work with a final (for me) infuriating flourish of seaweed and sticks.

No one methodology will explain to the uninitiated how to undertake the making of a sandcastle, and this is how it should be. Adopting an attentive mindset can open the possibilities for this immersive and bodily task.

Attending to sand

Particular qualities of sand can be revealed to those who remain aware. Building a sandcastle on a day after the rain can change the material and the way it presents.

Rain falling from the sky onto fine sand creates a crispy layer over the drier sand below. It is the crunchy feeling underfoot for those daily pioneers to the beach who arrive before these fragile structures are trampled underfoot. Rain creates a crust that would be difficult to produce any other way.

This and other states of sand could be considered on a continuum of material behaviours, from dry to wet, from dispersed to grouped, from fine to coarse, from quartz, through skeleton, to shell, or from a Newtonian to a non-Newtonian fluid.

In construction there is sharp sand, fat sand and sand of specific dimensions. The sand at the beach is the sand of that beach, undifferentiated by industrial ecologies and taken at its face value. Sluggish waterlogged mass, or blow away dust structure, compact sand, beige, black or grey – its specific qualities determining the outcome as much as the plan we bring to the task.

Working against collapse

Making objects with sand at the beach is a most egalitarian form of art making. Critiques of our constructions are generally of the generous kind. Passersby will applaud the magnitude of our creation, share in the joy as water fills our castle’s moats, and laugh shamelessly when the whole structure collapses.

Sand workers on the beach can adopt a critical position relative to the way the sand acts and be mesmerised by its characteristics as these present themselves. We can understand that sand slumps in a particular way, and compact it in anticipation. Or we can simply burrow furiously as it falls off in great slabs. Each reflects the personal attitude of the builder; neither is better than the other.

Seagrass, kelp, stones, glass and the egg sacs of moon snails may all present themselves for inclusion in a sandcastle. Driftwood will break through hard sand, create moats, or delineate space; large shells make excellent tools for moving bulk material, although using the body for scooping and compacting, or shoving and dragging, is perhaps the ideal way to engage the senses in the job. Collapse is the thing you work against.

Digging down and water begins to pool, piling the sand high and your castle begins to emerge.

Readers are advised this article contains offensive language about Aboriginal peoples.

Fifty years ago, on New Year’s Day in 1974, Wiradjuri woman Evonne Goolagong delighted spectators at Melbourne’s Kooyong Tennis Club by defeating American Chris Evert to win the women’s singles Australian Open championship.

The overflow crowd of 12,000 people leapt to their feet for a tremendously long and emotional ovation.

The Sydney Morning Herald reminded readers that no Aboriginal person had ever won an Australian tennis title. Of all the other major national dailies, only the Hobart Mercury alluded to race, describing Goolagong with offensive words such as “tawny” and “dark-skinned”.

On the surface, Goolagong’s victory transcended race and racial politics. Yet, she would later reflect that her stellar career, which included seven Grand Slam singles titles – sent a false message that all was okay in Australian racial politics:

See, we’re not holding them [Aboriginal people] back, we give them every opportunity.

Fast forward a couple of decades and Cathy Freeman was similarly touted as a symbol of reconciliation following her triumph at the 2000 Sydney Olympics.

From stamps to theatre productions

This appropriation of Goolagong Cawley (her married name) as a national symbol of racial harmony is echoed in a dizzying range of commemorations.

She holds several imperial and Australian honours, including Australian of the Year in 1971, a Member of the Order of the British Empire and a Companion of the Order of Australia.

A giant tennis racket looms over her hometown of Barellan, NSW, in her honour, a bronze bust of her welcomes visitors to Melbourne Park (the current home of the Australian Open), and public artworks dedicated to her abound.

Yorta Yorta/Gunaikurnai playwright Andrea James brought Goolagong Cawley’s life story to the stage several years ago and Australia Post has honoured her twice with her own stamps.

Sport has not overlooked Goolagong Cawley, either. She has been inducted into the Sport Australia Hall of Fame, the International Tennis Hall of Fame and the Australian Tennis Hall of Fame.

And in this anniversary year, her currency is at an all-time high: her image will appear on the Australian Open 2024 coin, as well as on a range of merchandise, designed by Lyn-Al Young, a Gunnai, Wiradjuri, Gunditjmara and Yorta Yorta artist.

Goolagong Cawley is proud of her many honours – and she should be. But as historian Karen Fox argues, these honours can be used by some to cast her as a potent symbol of Australia’s supposed sporting egalitarianism. This, in turn, can help assuage white guilt over historic injustices against First Nations people, including genocide, dispossession, marginalisation, racism and exclusion.

It’s also important to remember what she had to overcome to reach the pinnacle of achievement and recognition in her sport – and the ongoing issues that Aboriginal and Torres Strait Islander people continue to face.

Contending with racism

Evonne Goolagong was born in 1951, which was a fraught period for First Nations people in this country. On the day she was born (July 31), a quick glance of the national media reflects the widespread racism, discrimination, ignorance and suspicion that many Aboriginal and Torres Strait Islander people faced.

There were stories about:

• protests in a NSW town over the decision to give “liquor freedom” to Aboriginal people

• misgivings about the ability of Aboriginal people to accept Christianity

• assertions that Aboriginal people didn’t actually live in North Queensland

• a requirement for half-caste (sic) people in the Northern Territory to carry certificates of exemption

• and an actress’s black-face make-up tips.

Goolagong grew up in the only Aboriginal family in Barellan. In an interview in 2015, she recalled her mother being worried the “welfare man” might steal her children. In a biography in 1993, she also said her father feared that “whatever he tried to accomplish, the white man would take away”.

By 1974, the rights of Indigenous people in Australians were improving. First Nations people had been granted the right to vote in all states and territories, though full equality wasn’t reached until enrolment was compulsory in 1984. The 1965 Freedom Ride had drawn attention to discrimination. The 1967 referendum meant Indigenous people could be counted in the national census. And in 1972, Gough Whitlam’s new Labor government established a royal commission into Aboriginal land rights and created the Department of Aboriginal Affairs.

The 1967 referendum was the most successful in Australia’s history. But what it can tell us about 2023 is complicated

Yet, terrible racism remained. When Vic Edwards, who would later become Goolagong Cawley’s coach, first spotted her talent in the early 1960s, he noted the “Aboriginal aspect might not sit well in tennis circles”.

He was right. Goolagong Cawley shrugged off most insults, but they were truly shocking. She recalled a white woman calling her the n-word while shaking hands after a match and being denied entry to a Brisbane nightclub because of her skin colour.

Commentators frequently attributed her on-court concentration lapses to going “walkabout” – Fox, the historian, counted 18 uses of the word in Australian newspaper articles about her in 1980. Fox also recounted an anecdote that an unnamed state premier said he hoped she “wouldn’t go walkabout like some old boong” before her 1980 Wimbledon match.

These types of racial sentiments were ever-present throughout her career. As she became more successful, she also faced a repression of her heritage in the media and appropriation by white Australia. In an interview in the early 2000s, she said:

[…] the more successful I became, the whiter I seemed to become.

The Uluru Statement from the Heart) has called for truth-telling across the nation. This 50th anniversary of Goolagong Cawley’s Kooyong win provides one opportunity for this – a recognition of the racial realities behind the burnished brass, bright lights and shining prestige of the various honours bestowed upon her.

Despite 2023 having been the sixth year a national day of commemoration for the New Zealand Wars was observed, it’s debatable how many New Zealanders really knew much about it.

Historians and Māori leaders are now worried about the mixed impact of the day – known as Te Pūtake o te Riri – amid wider fears it is already slipping from public attention.

The day was conceived as an important step towards greater public awareness of the major 19th-century conflicts between Māori and the settler government. It was first named He Rā Maumahara in 2016, “in honour of those who made sacrifices in wars and conflicts within Aotearoa New Zealand”.

The day was given its new name after consultation with iwi, and October 28 designated as the annual date of observance. Unlike Anzac Day, however, Te Pūtake o te Riri was not made an official holiday – and this may partly explain its struggle for wider recognition.

A question of timing

The day’s name is a compound of “Te Pūtake”, meaning the root or cause, and “te riri”, the anger or conflict. It emphasises Māori experiences, and each year’s commemoration is hosted by different hapū and iwi.

In 2023, for example, it focused on Ngai-te-rangi perspectives of the battle of Pukehinahina – “Gate Pā” – in Tauranga.

Despite an initial groundswell of interest and support, COVID inevitably disrupted observance of the day. But there have also been questions about the choice of October 28 in the first place.

Historian Danny Keenan argues the date – which marks the signing in 1835 of He Whakaputanga, the Declaration of Independence – dilutes the focus on what were first and foremost military conflicts.

Sociologist and Māori educationalist Joanna Kidman also blames a lack of basic understanding by Pākehā New Zealanders of the New Zealand Wars, and the continued emphasis on World War I and other 20th-century conflicts.

Evolution of Anzac Day

The comparison with the first world war invites an intriguing question: what lessons might we learn from the history of our most visible war commemoration, Anzac Day?

In fact, April 25 itself has had its own ups and downs, shaped by New Zealanders’ shifting connection to the British Empire. The rhetoric and practice of a national commemoration, led by the prime minister, didn’t appear until the 1990s.

Indeed, in 1965, the 50th anniversary of Gallipoli, there were real doubts Anzac Day could survive the passing of the last Anzac veterans.

New lessons about old wars: keeping the complex story of Anzac Day relevant in the 21st century

Instead, it has survived as a sacred day – helped perhaps by the 1920 Anzac Day Act which made it an official public holiday. (The Act also banned public entertainment and other “profane” activities such as drinking in pubs and horse racing on April 25.)

The day’s remit was expanded in 1949 to commemorate all wars fought by New Zealand soldiers since the Boer War (1899-1902). But there was ongoing debate over whether the RSA and government had the right to make New Zealanders observe any particular “sacred” activity.

The law was liberalised in 1966 to allow people to do what they wanted after morning services ended at 11am. It was recognised that moving from solemnity to relaxation might avoid the risk of people simply rejecting the remembrance entirely.

War memorials and public memory

The growing public ownership of Anzac Day ran parallel to the decline of Armistice Day, which marked the end of the World War I on November 11.

On a par with April 25 until the 1940s, there was a near-immediate collapse in public support when the government moved observance to the nearest Sunday. This
suggests legislative status can be a significant factor in shaping attitudes to remembering the past.

The survival of Anzac Day, unlike November 11, also reflected the physical landscape of commemoration. No New Zealand town was too small to claim a local memorial to the fallen. As the sculptor Brett Graham has noted, war memorials became the dominant sculptural form of public life.

Nowadays, they are among the nation’s most prominent public sites, including the Auckland War Memorial Museum, the Pukeahu National War Memorial in Wellington, and Christchurch’s Bridge of Remembrance.

These memorial sites have retained their importance due to the efforts and investment of dedicated groups. Veterans and other social networks, expanded over the years to reflect a more diverse New Zealand, have been vital to the evolution of Anzac ritual.

Solidarity and difference — how Anzac Day reflects an ever-changing New Zealand

Gallipoli and national unity

Protests on Anzac Day (against war but also other social issues) also raised new questions about the purpose of the commemoration and its role in public life.

Significantly, the Gallipoli story – the central focus of our Anzac mythology – has been adapted and retold by each generation. Speeches, newspaper accounts, memoirs and official histories initially forged this mythical element, complete with heroes and martyrs, as well as villains (the German-Ottoman forces, later the British Empire itself).

In the 1980s, playwrights, documentary makers and film directors re-visualised the imperial Anzac story as appealing nationalist myths. Māori Television (Whakatā Māori) established a national Anzac Day broadcast in 2005, deepening the shared cultural languages and motifs of April 25.

Since the 1990s, successive governments – especially Helen Clark’s in the early 2000s – invested in Anzac Day as a commemoration of national unity.

A key milestone was the repatriation of the unknown warrior in 2004, observed by 100,000 New Zealanders who lined the streets of Wellington for the funeral procession and burial at Pukeahu. The state-funded Anzac Centenary in 2015 was the largest commemoration in New Zealand history.

Need for a national policy

What would a comparable state investment in New Zealand Wars commemoration look like? Some have suggested Te Pūtake o te Riri will never achieve the necessary public attention until it becomes a statutory holiday.

There are other challenges, too. As Joanna Kidman noted, many New Zealand Wars cemeteries, memorials and battlefields have been neglected or are on private land. Increasing public access to these sites will require a coordinated – and expensive – effort by local councils and central government.

It’s not enough, though, simply to transplant Anzac cultural and political symbols and language onto Te Pūtake o te Riri – an unknown warrior of our colonial conflicts, resting in Pukeahu’s Hall of Memories, for example.

Ngāti Maniapoto historian Kawhia Te Murahi has called for a unique “blending” of Māori and Pākehā tikanga and kawa for the day.

The issues raised all point to the need for a national policy on the commemoration of the New Zealand Wars – guided by iwi, with critical input from scholars – that enhances community relationships.

New ways of remembering

In 2023, a striking example of the potential for war commemoration to take new directions took place at Te Rau Aroha, the museum at Waitangi dedicated to the contribution of Māori to the nation’s involvement in wars since 1840.

After its service on October 28, the museum hosted whānau descendants of 28th Māori Battalion veterans who had never claimed their medals for serving in World War II.

By choosing Te Pūtake o te Riri for the ceremony, the organisers were able to bridge past and present through themes of service, sacrifice and citizenship. As trusted institutions of public memory, museums are ideally placed to tell the stories of the New Zealand Wars.

Commemoration doesn’t happen by chance – it reflects the work of individuals, networks and institutions dedicated to promoting and framing a society’s defining narratives.

Both local initiative and state investment are important here. Above all, communities want to remember and commemorate the nation’s violent past. Anyone contributing to changes in public commemorative culture needs to understand this, and be guided by history.

We’re all time-poor, so multi-tasking is seen as a necessity of modern living. We answer work emails while watching TV, make shopping lists in meetings and listen to podcasts when doing the dishes. We attempt to split our attention countless times a day when juggling both mundane and important tasks.

But doing two things at the same time isn’t always as productive or safe as focusing on one thing at a time.

The dilemma with multi-tasking is that when tasks become complex or energy-demanding, like driving a car while talking on the phone, our performance often drops on one or both.

Here’s why – and how our ability to multi-task changes as we age.

Read more:
Women aren’t better multitaskers than men – they’re just doing more work

Doing more things, but less effectively

The issue with multi-tasking at a brain level, is that two tasks performed at the same time often compete for common neural pathways – like two intersecting streams of traffic on a road.

In particular, the brain’s planning centres in the frontal cortex (and connections to parieto-cerebellar system, among others) are needed for both motor and cognitive tasks. The more tasks rely on the same sensory system, like vision, the greater the interference.

This is why multi-tasking, such as talking on the phone, while driving can be risky. It takes longer to react to critical events, such as a car braking suddenly, and you have a higher risk of missing critical signals, such as a red light.

The more involved the phone conversation, the higher the accident risk, even when talking “hands-free”.

Generally, the more skilled you are on a primary motor task, the better able you are to juggle another task at the same time. Skilled surgeons, for example, can multitask more effectively than residents, which is reassuring in a busy operating suite.

Highly automated skills and efficient brain processes mean greater flexibility when multi-tasking.

Adults are better at multi-tasking than kids

Both brain capacity and experience endow adults with a greater capacity for multi-tasking compared with children.

You may have noticed that when you start thinking about a problem, you walk more slowly, and sometimes to a standstill if deep in thought. The ability to walk and think at the same time gets better over childhood and adolescence, as do other types of multi-tasking.

When children do these two things at once, their walking speed and smoothness both wane, particularly when also doing a memory task (like recalling a sequence of numbers), verbal fluency task (like naming animals) or a fine-motor task (like buttoning up a shirt). Alternately, outside the lab, the cognitive task might fall by wayside as the motor goal takes precedence.

TikTok may be bad for privacy, but is it also harming our cognitive abilities?

Brain maturation has a lot to do with these age differences. A larger prefrontal cortex helps share cognitive resources between tasks, thereby reducing the costs. This means better capacity to maintain performance at or near single-task levels.

The white matter tract that connects our two hemispheres (the corpus callosum) also takes a long time to fully mature, placing limits on how well children can walk around and do manual tasks (like texting on a phone) together.

For a child or adult with motor skill difficulties, or developmental coordination disorder, multi-tastking errors are more common. Simply standing still while solving a visual task (like judging which of two lines is longer) is hard. When walking, it takes much longer to complete a path if it also involves cognitive effort along the way. So you can imagine how difficult walking to school could be.

What about as we approach older age?

Older adults are more prone to multi-tasking errors. When walking, for example, adding another task generally means older adults walk much slower and with less fluid movement than younger adults.

These age differences are even more pronounced when obstacles must be avoided or the path is winding or uneven.

Older adults tend to enlist more of their prefrontal cortex when walking and, especially, when multi-tasking. This creates more interference when the same brain networks are also enlisted to perform a cognitive task.

These age differences in performance of multi-tasking might be more “compensatory” than anything else, allowing older adults more time and safety when negotiating events around them.

Older people can practise and improve

Testing multi-tasking capabilities can tell clinicians about an older patient’s risk of future falls better than an assessment of walking alone, even for healthy people living in the community.

Testing can be as simple as asking someone to walk a path while either mentally subtracting by sevens, carrying a cup and saucer, or balancing a ball on a tray.

Patients can then practise and improve these abilities by, for example, pedalling an exercise bike or walking on a treadmill while composing a poem, making a shopping list, or playing a word game.

The goal is for patients to be able to divide their attention more efficiently across two tasks and to ignore distractions, improving speed and balance.

There are times when we do think better when moving

Let’s not forget that a good walk can help unclutter our mind and promote creative thought. And, some research shows walking can improve our ability to search and respond to visual events in the environment.

But often, it’s better to focus on one thing at a time

We often overlook the emotional and energy costs of multi-tasking when time-pressured. In many areas of life – home, work and school – we think it will save us time and energy. But the reality can be different.

Multi-tasking can sometimes sap our reserves and create stress, raising our cortisol levels, especially when we’re time-pressured. If such performance is sustained over long periods, it can leave you feeling fatigued or just plain empty.

How much energy do we expend thinking and using our brain?

Deep thinking is energy demanding by itself and so caution is sometimes warranted when acting at the same time – such as being immersed in deep thought while crossing a busy road, descending steep stairs, using power tools, or climbing a ladder.

So, pick a good time to ask someone a vexed question – perhaps not while they’re cutting vegetables with a sharp knife. Sometimes, it’s better to focus on one thing at a time.

Across the vast Australian continent, feral pigs, feral deer and European rabbits roam in their millions. By different names – wild boar, venison and lapin – these could all be served in a Michelin star restaurant.

Feral and invasive species are becoming popular meals for native wildlife too. For species like the saltwater crocodile and spotted-tailed quoll, the menu is expanding and changing due to the arrival of invasive alien species – one of the greatest threats to biodiversity globally.

The good news is, many invasive alien species make good tucker. Around the world, native wildlife are dining on increasing numbers of exotic prey. In the United States, endangered snail kites — a wetland raptor — crunch through invasive apple snails, red-banded snakes swallow North American bullfrogs in China, dingoes devour feral sambar deer and goats in Australia, Sulawesian toads gobble up introduced yellow crazy ants in Indonesia, and golden eagles and saltwater crocodiles both love eating feral pigs on opposite sides of the Pacific.

Of crocs and pigs

So can we say these invasives are useful in some sense? Exotic prey can help boost numbers of some native predators. Saltwater crocodiles in the Northern Territory are rapidly bouncing back after widespread, severe culling.

Using the bones of crocodiles collected through time, researchers have shown that over roughly half a century, salties have shifted from a diet largely based on fish to a more terrestrial diet, including feral water buffalo and pigs.

This seems like a much-needed good news story for the environment – a natural way to limit feral pigs, one of Australia’s most widespread and damaging invasive species. At present, though, we don’t know for sure that crocs keep pig numbers down.

Pigs and crocodiles live in the fast and slow lanes, respectively. Feral pigs feed and breed, and few things are off the menu. Sows can give birth from around 6 months of age, and produce ten or more piglets in litters once or twice every 12 or so months.

On the other hand, female estuarine crocodiles begin reproducing at around 12 years of age, and do so once a year under the right conditions. Crocodiles cut back on hunting and other activity during cooler months. Together, this means feral pigs can endure relatively high predation rates and still persist in ecosystems in large numbers.

Of quolls and rabbits

The largest of Australia’s four predatory marsupial quoll species, the spotted-tailed quoll, is known to enjoy rabbit even when there is a diverse and abundant selection of native mammals within the same area.

Unfortunately, quolls are now absent or still declining in many places, due likely to competition or predation with the bigger, heavier predators Europeans introduced: feral cats and foxes. In the bush, male cats can be sizeable – exceeding 6 kilos, roughly double the size of your average spotted-tailed quoll.

As quolls have disappeared, rabbits may have taken advantage of the predatory void and expanded. Fast-breeding rabbits are now arguably Australia’s worst invasive alien species. Their sheer numbers support cat and fox populations.

This begs the question – if cats and foxes could be eradicated or greatly reduced in some areas, could we reintroduce quolls to help manage rabbit populations or prevent their return?

Dangerous dinners

Not all introduced prey make safe meals.

Cane toads have devastated some native species such as northern quolls, which naturally prey on native amphibians but cannot survive toad toxin.

Regrettably, a recent attempt to train quolls not to eat cane toads appears to have failed.

But other species have learnt to safely eat cane toads, including the rakali (Australian water rat), which removes and eats toad hearts and livers with surgical precision. The humble bin chicken (white ibis) has also figured out how to make toads safer by washing them.

European house mice and introduced rats can be easy prey for owls, snakes, and many other native predators. Unfortunately, these easy pickings can become their last suppers – not because the rodents are toxic, but because they may well have eaten rodenticide which makes them easier to hunt. Once a sick, dying rodent is eaten, the predator can in turn be poisoned and die. Scavengers who eat poisoned predators can also die, affecting entire food chains and ecosystems.

Sometimes predators can find themselves prey, depending on their age and size. In Australia, large pythons, goannas and monitor lizards eat foxes and cats, but these same reptiles are preyed upon by cats and foxes when younger and smaller.

Invasive prey aren’t going away

As time goes on, invasive prey species can become regular meals for native predators – and part of the food web.

When we try to remove invasive prey species from ecosystems, we must take a big picture view and proceed with great caution.

When feral cats were killed off on New Zealand’s Little Barrier island, it was done with the best intentions: protect the seabirds nesting there. But with the cats gone, invasive rat populations surged and soon began killing the seabird chicks.

In Australia’s arid regions, we now have experimental evidence to suggest biological controls such as rabbit haemorrhagic disease do keep rabbit numbers down, alongside culling and destroying warrens. With the rabbits suppressed, plants and native herbivores can bounce back. This, in turn, pushes cat and fox populations lower, as these two predators maintain their high numbers in arid regions in part due to an abundance of rabbits.

But this doesn’t work in the wetter, more vegetated south-east. Here, there’s little evidence rabbit control greatly affects fox populations.

So should we celebrate crocs chomping on pigs and rakali eating cane toads? Of course – it’s a sign that some of our native predators can adapt to these introduced species. But it’s not true for all native wildlife. Our quolls are doing far worse with the new arrivals.

And for every native predator finding new tucker, there are far more cats and foxes eating birds, reptiles, frogs, and small marsupials, while pigs, deer, camels, horses, donkeys, and water buffalo run amok. We have already set these creatures loose – we must use all means possible to try and rein them in.

You buy a new phone case from an online retailer. The phone case arrives safely at your house, the online retailer makes a small profit and everyone is happy.

But the phone case didn’t come from the retailer’s premises. It was sent directly from the manufacturer. The only thing the online retailer did was take your order and organise for the factory to deliver the case to your home.

This is “dropshipping”: where an online seller organises to have purchased products sent to buyers directly from the wholesaler or manufacturer, rather than sending it themselves. Many see dropshipping as, if not their main business, then as a valuable side hustle to help bolster income when the cost-of-living crunch is making it hard to make ends meet.

In other words, the seller doesn’t own a warehouse of products ready for shipping. They’re a middleman. They organise delivery of products to customers without taking physical possession.

Dropshipping may sound like an appealing side hustle to help offset the cost-of-living crunch but there are downsides, too.

So, what do you need to know before you become a dropshipper?

Temu: China’s answer to Amazon is already Australia’s most popular free app. What makes it so addictive?

There are pros and cons

Dropshipping has doubled since 2020, and is expected to double again by 2027.

Websites with e-commerce features are also increasingly affordable, and since the barrier to entry for starting a dropshipping business is low, it has become a popular method for making extra money.

Dropshipping eliminates “inventory costs”, which includes things like:

• buying the products upfront

• paying warehouse rent, and

• paying staff to package and ship.

Since dropshippers don’t need to hold any inventory, they’re able to offer a wider selection of products to sell. Low startup costs also make dropshipping more accessible to a wider range of people than traditional businesses.

So dropshipping has clear advantages over traditional methods of selling online – but it’s not all rosy.

The main problem with dropshipping is loss of control over the delivery and fulfilment process.

If a problem with delivery arises, it can be more difficult to resolve. Is the problem with the manufacturer? The warehouse? The delivery service? Sometimes it can be unclear and take longer to address than the customer would like.

This can threaten the seller’s ability to offer superior customer service.

Here are six things worth knowing before you launch into dropshipping as your side hustle.

1. Supplier reputation matters

Dropshipping isn’t new – brands in the late 1990s were doing it. But with this maturity has arisen opportunities for fraud.

Counterfeits, knock-offs, and general quality issues are worryingly commonplace in the dropshipping world.

Choose a reputable supplier with clear systems and processes to control product quality and eliminate copyright infringement.

2. Choose a local supplier

To remain competitive, delivery speed is key. If your target audience is in Australia, shipping from foreign soils won’t cut it – the delivery times are too long.

Consumers are willing to wait to receive their products on some occasions, but most of the time consumers want it now.

Choose a local, reputable supplier to minimise delivery times.

3. Don’t assume quality

One of the biggest mistakes dropshippers make is not physically inspecting products before listing them for sale.

Dropshipping enables sellers to offer a wider range, since shelf-space isn’t an issue. But that may tempt you to keep adding new products to the catalogue.

The quality of products from dropshipping suppliers varies considerably, and what looks great on screen might look very different in hand.

Selling poor quality products means more customer service requests, and ultimately consumers start to associate your brand with poor quality.

Always get a new product sent for physical inspection before listing them in your sales catalogue.

4. Develop a relationship with your supplier

The best way to resolve potential delivery issues associated with dropshipping is to build a strong relationship with the supplier.

Many suppliers do not offer support services when things go wrong. These suppliers should be treated with caution.

Developing a strong, collaborative relationship with a willing supplier makes service failures easier to deal with.

5. Stand out from the crowd

Doing business online is not easy – all your competitors are just a click or a tap away. Dropshipping is common, and many other websites are selling the same things as you, potentially from the same supplier.

Standing out from the crowd is key. Differentiate yourself from other dropshippers by servicing niche markets and offering superior after-sales support.

6. The customer sets demand

Don’t add more and more products to your catalogue until you’re offering everything under the sun; this sets you up for failure because you end up offering everything to no-one.

Specialisation is key. Find an easily reachable and sizeable audience and stick to what they want, not what you think they want.

Careful attention to sales data will help clarify what it is your customers are telling you they want.

If you’ve watched many period dramas, you’ve probably seen a mantua before. Originating in France in the 1670s, this women’s garment consisted of lengths of t-shaped fabric that were pleated to create an unstiffened bodice with attached overskirts.

This gown was worn over a pair of stays (corset) and an often contrasting petticoat. The draping and folding of fabric created a front-opening gown.

What many people don’t realise, however, is how fundamentally this item of clothing altered women’s involvement in the fashion industry – and represented a ticket to financial freedom for an industry of female mantua makers.

What was the mantua?

After its invention in the 1670s, the new gown became immediately popular among fashionable Parisian women.

Although strict dress codes at the Versailles court of French King Louis XIV prohibited the wearing of mantuas, women at the English court helped popularise it in England.

By the 1680s, the mantua was widely worn in Western and Central Europe, as well as in European colonies around the world. It soon became the basis for all women’s gowns in the 18th century.

Popular versions of the mantua in 18th century included:

• the loose style called a robe volante

• the iconic robe à la française (sometimes called a sack gown) with its back pleats that draped to the floor, and

• the tighter fitting robe à la anglaise (also known as English or Italian gowns).

Tailors vs mantua makers

As well as changing the look of western fashions, the mantua radically changed women’s involvement in the fashion industry.

Before the 17th century, outer garments were usually made by male tailors. Apprenticeships and membership of guilds – the organisations that controlled most craft trades – were restricted to boys and men.

Women did participate informally in these professions. They sometimes worked alongside tailor family members (and some were fined for doing so) and widows were permitted to carry on the businesses of their deceased husbands.

Women had also historically worked as seamstresses or “silkwomen” making small linen or silk goods like underwear and accessories.

However, this began to change in the late 17th century during what came to be known as the consumer revolution – a period, beginning in the 1600s, that saw a significant jump in the consumption of luxury goods.

Significantly, in 1675, women in Paris and Rouen acquired their own, independent couturière (dressmaking) guilds and began to take over making women’s clothing from male tailors.

In London, guilds with dwindling memberships also began to permit paying female members.

Due to the considerable influence of France on western fashions, women in London began to train under French dressmakers, giving rise to what were known in English as mantua makers.

Dressmaking and financial freedom

From the 18th to 20th centuries, dressmaking and other fashion or textile-related industries were the main source of formal employment for women in Britain, Australia and the United States (alongside teaching and domestic service).

New training opportunities in dressmaking – coupled with historical peculiarities such as London’s feme sole status, which allowed married women to run businesses and have finances independent of their husbands – meant many women began to open their own businesses.

Single women often lived in houses with other mantua makers and their apprentices, working as teams. Married women usually operated in workshops in the family home alongside their husbands, many of whom worked as tailors.

By the mid-18th century, manuals instructing parents on craft apprenticeships for their children noted mantua making was a large trade

reckoned a genteel, as well as profitable Employ [for women], many of them living well and saving Money.

But several male tailoring guilds in Europe attempted to stop women working as mantua makers, claiming they were taking away their business. Additionally, many women who worked in the garment-making industries were poorly paid and often worked in cramped conditions.

Yet, many did rise above. French mantua makers were particularly popular, with women in London paying substantially more for gowns made by French women with access to the latest fashion knowledge in Paris.

Some became confidants of queens. The famous fashion merchant Marie-Jeanne “Rose” Bertin designed many of French queen Marie Antoinette’s gowns (her detractors labelled her the queen’s “minister of fashion”).

These networks gave these women access to vast amounts of clients and social capital. By the 19th century, senior dressmakers and milliners called modistes often ran their own luxury fashion houses in the West End of London.

Mantua making was also a significant business opportunity for women in Australia.

“M. Hayes”, Catherine Mellon and Martha Matthews were all “mantua makers and milliners” who advertised their services in the early years of the Sydney colony.

Legacies of mantua makers

During the early years of the 19th century, mantuas fell out of use as new styles appeared. The term “dressmaker” also came to slowly replace the term “mantua maker”.

However, the gendered segregation of labour remained. During much of the 19th and 20th centuries, men were more likely to be tailors and have their clothing made by tailors. Women were more likely to be dressmakers and have their clothing made by dressmakers. The skills and techniques of each profession remained quite different.

With the advent of modern fast fashion, the skills of both tailors and dressmakers are fast being lost, and with it the knowledge of this revolutionary trade for women.

John Pilger, a giant of journalism born in Australia in 1939, has died at the age of 84, according to a statement released online by his family.

His numerous books and especially his documentaries opened the world’s eyes to the failings, and worse, of governments in many countries – including his birthplace.

He inspired many journalists, and journalism students, with his willingness to critique the damaging effects on ordinary people’s lives of capitalism and Western countries’ foreign policies, particularly the United States and the United Kingdom.

But his campaigning approach to journalism also regularly provoked controversy. That was partly because of his trenchant dissent from official stances, and partly because in aiming to reach the broadest possible audience, he tended to oversimplify issues and overstate his views.

More than one journalist per day is dying in the Israel-Gaza conflict. This has to stop

‘I am, by inclination, anti-authoritarian’

The English journalist, Auberon Waugh, who clashed with Pilger on more than one occasion, invented the verb “to pilger” which he defined as “to treat a subject emotionally with generous disregard for inconvenient detail, always in the left-wing cause and always with great indignation”.

Whatever the merits of Waugh’s criticism, they are, in my view, outweighed by the breadth and depth of Pilger’s disclosures in the public interest.

Pilger never hid behind the safety of the “he said, she said” approach to journalism, which New York University professor Jay Rosen has famously called the “view from nowhere”.

Pilger, however, rejected the label of crusader, telling Anthony Hayward for his book, In the Name of Justice: The Television Reporting of John Pilger:

I am, by inclination, anti-authoritarian and forever sceptical of anything the agents of power want to tell us. It is my duty, surely, to tell people when they’re being conned or told lies.

Telling the stories of ordinary people

Pilger was born in Bondi, Sydney. Like many of his generation, he moved to the UK in the early 1960s and worked for The Daily Mirror, Reuters and ITV’s investigative program World in Action.

He reported on conflicts in Bangladesh, Biafra, Cambodia and Vietnam and was named newspaper journalist of the year in Britain in 1967 and 1979.

He made more than 50 documentaries. His best known is Year Zero: the Silent Death of Cambodia, which in 1979 revealed that as many as two million of the seven million population of the country had died as a result of genocide or starvation under Pol Pot’s brutal regime.

His documentaries garnered numerous prizes, including the prestigious Richard Dimbleby award for factual reporting, a Peabody award for Cambodia: Year Ten and a Best Documentary Emmy award for Cambodia: The Betrayal.

He also made several documentaries about Australia, including one in 1985, The Secret Country, about historic and continuing mistreatment of First Nations people that thoroughly irritated the then Labor prime minister, Bob Hawke.

When the US government of George W. Bush reacted to al-Qaeda’s murderous 9/11 terrorist attacks by invading first Afghanistan, in late 2001, then Iraq in March 2003, Pilger made Truth and Lies: Breaking the Silence on the War on Terror.

It sharply criticised not only Bush’s actions but those of the most ardent members of the “coalition of the willing”: UK Labour prime minister, Tony Blair, and Australian coalition prime minister, John Howard.

No doubt, if Pilger was still alive he would condemn the absence of the National Security Committee’s papers from the 2003 cabinet papers released today by the National Archives of Australia.

They show Howard’s cabinet signed off on the controversial – in hindsight disastrous – decision to endorse the Bush administration’s plan to invade Iraq based on “oral reports” from the prime minister, rather than full cabinet submissions.

Pilger wrote or edited 11 books, including Tell Me No Lies, an anthology of outstanding investigative journalism, and perhaps his best regarded book, Heroes, which hewed to what one of his favourite journalists, Martha Gellhorn, called “the view from the ground”.

He did this by telling the stories of ordinary people he had encountered, whether miners in Durham, England, refugees from Vietnam, or American soldiers returning from the Vietnam War – not to parades, but to lives dislocated by the silence and shame surrounding the war’s end.

The world has lost a resolutely dissenting voice

Phillip Knightley, a contemporary of Pilger who was also born in Australia and went to Fleet Street to become a celebrated investigative journalist and author himself, summed up his compatriot’s work in 2000:

He was certainly among the first to draw international attention to the shameful way in which Australia has treated the Aborigines [sic] […] John has a slightly less optimistic view than I have.

In Welcome to Australia [Pilger’s 1999 film], he concentrated on the bad things that were happening but not the good. He would say that’s not part of his brief and it’s covered elsewhere. He’s a polemicist and, if you want to arouse people’s passions and anger, the stronger the polemic, the better.

Pilger made fewer films in the 2000s, focusing much of his energy on supporting Julian Assange, founder of WikiLeaks. Assange continues to suffer in Belmarsh prison in England while appeals against his extradition to the US to answer charges under the 1917 Espionage Act grind interminably on.

Whatever flaws there are in Pilger’s journalism, it feels dispiriting that on the first day of a new year clouded by wars, inaction on climate change and a presidential election in the US where democracy itself is on the ballot, the world has lost another resolutely dissenting voice in the media.

While the unaided eye or binoculars can reveal much of the night sky, a telescope reveals so much more. Seeing Saturn’s rings or the Moon’s craters with your own eyes can be an “oh wow” moment.

However, choosing the right telescope can be tricky. There are telescopes with lenses and telescopes with mirrors. Telescopes that are moved by hand and others that are electronically controlled. Telescopes also come in a range of sizes, with a trade-off between light-gathering power, portability and price.

While there’s much to consider, changes in pricing and technology mean spectacular views of the universe are more accessible than just a decade ago.

How big should the aperture be?

Aperture is fundamental for telescopes. The bigger the light-collecting lens or mirror, the fainter the objects you can see. Double the aperture from 50mm diameter to 100mm diameter, and the light-collecting area quadruples.

The aperture also limits the level of detail you can see, due to the diffraction (interference) of light.

Again, bigger is better – a larger aperture telescope will produce sharper images than a smaller aperture telescope of comparable design. Earth’s turbulent atmosphere also blurs images, which can limit the detail seen when the aperture is more than 150mm.

Sometimes cheaper telescopes are advertised by magnification, but a small telescope with extreme magnification just makes blurry images bigger without revealing more detail.

Refractor or reflector?

Should you buy a telescope with a refracting lens or a reflecting mirror? It depends what you want to look at, and your budget.

Refracting telescopes

Refracting telescopes can be good for viewing objects on Earth and in the sky. Refracting telescopes with short focal lengths (where light is brought to a focus near the lens) can be quite compact and good for low magnification views, which is great for sweeping across dark country skies.

However, there are catches. While 70mm aperture refracting telescopes can be quite affordable, bigger refractor telescopes are often more expensive than comparable reflecting telescopes.

Refracting telescopes also suffer from chromatic aberration – where different colours aren’t brought to a common focus – and this is particularly noticeable at high magnification when stars get coloured halos. This can be mitigated using complex lens designs, but that adds to the cost.

Reflecting telescopes

Reflecting telescopes use mirrors to focus light. These tend to be larger and don’t suffer from chromatic aberration.

Dobsonian telescopes have a simple Newtonian optical design and wooden mounts, and are a very cost effective (if sometimes bulky) option for larger apertures. Schmidt-Cassegrain and Maksutov telescopes, which use a combination of lenses and mirrors, are more compact (a big plus), but also more complex and expensive.

How do I find things in the sky? Depends on the mount

Want to look at a celestial object? You will need to point your telescope in the right direction, keep it steady, and follow the object as it moves across the sky (due to Earth’s rotation).

To do this, a telescope needs a mount, which is often sold with the telescope but can also be bought separately. Mounts fall into two broad categories.

Equatorial mounts have an axis aligned with Earth’s axis, so a single motor can compensate for Earth’s rotation. These mounts were essential for taking long exposure images with telescopes prior to computers and tend to be relatively heavy.

Alt-azimuth mounts have a vertical and a horizontal axis (how a camera is mounted on a tripod, for example), and tend to be cheaper and lighter than equatorial mounts. With the advent of cheap computing, they can now be used to automatically point at and track celestial objects.

To point a telescope at celestial objects you can move it manually or have electronics assist you, including “goto” mounts with motors that shift the telescope for you.

A completely manual telescope will be cheaper than a telescope with automation, but you will need to navigate the sky yourself.

Electronic assistance for navigating the sky is rapidly evolving and getting cheaper. Many telescopes on the market now use GPS and a smartphone app, which simplifies the process and makes everything more portable.

Do I need a finder scope?

Regardless of how you point your telescope, having a 30–50mm aperture auxiliary “finder” scope can be useful for small telescopes and essential for larger telescopes.

Large telescopes typically view a tiny patch of the sky, which makes finding your way tricky. A finder scope with a wider view and crosshairs simplifies things. Even telescopes with goto electronics often need to be calibrated with bright stars and locating them is easier with a finder scope.

What about the eyepiece?

An essential part of most telescopes is the eyepiece you look through. Sometimes decent telescopes are sold with quite cheap eyepieces, but it can be relatively inexpensive to upgrade to a better one.

A good start is a low-magnification eyepiece for sweeping views, and a high-magnification eyepiece for planets.

Plössl eyepieces are affordable and provide good views. More complex eyepieces that provide better views are also available, and far cheaper than they once were.

If you want to look at the Sun, you must get a specially designed solar filter. Never point a telescope (including the finder scope) at the Sun without filters – it can permanently damage eyes and shatter lenses.

What if I want to take astro photos?

Taking basic astronomical photos has become much easier with smartphones. While you can hold a phone to the telescope eyepiece for a photo of the Moon or a planet, you will get better results with an adapter that holds your phone securely in place.

Of course, better images can be taken with astronomy-specific cameras that can take very short exposures (for planets) or very long exposures (for fainter nebulae and galaxies). For long exposures, automatic tracking of celestial objects is essential, and that adds to a telescope’s price.

Smart telescopes are a relatively recent addition to the market. These goto telescopes have no eyepieces and only capture images electronically. As modern detectors are more sensitive than our eyes, they can capture quite spectacular images with a relatively small portable telescope, even when there’s light pollution.

However, you do lose the experience of seeing the universe directly with your own eyes through the eyepiece.

Try before you buy!

If there’s a local amateur astronomical society, you can sign up or attend a star party. There should be plenty of telescopes, and owners happy to wax lyrical about them.

A specialist shop can also give a direct experience of a telescope: its size and how it works (with limitations during daytime). For example, you may find a telescope is too bulky or technical for your needs.

Online shopping can save money, but may have less customer support than a local shop. You could also snap up a bargain buying second hand, and a seller may allow you to test their telescope on the Moon and planets before buying.

There’s a lot to take on board before buying a telescope. Aperture, size, cost and other factors need to be considered. But there are many good options out there, and with a good choice you can see some wondrous things. And perhaps have an “oh wow” moment.

By far the most significant decision the Howard government made in 2003 was to support the invasion of Iraq. Journalists and historians have long maintained there was no submission to full cabinet weighing the pros and cons of the Australian intervention. Cabinet papers from 2003 released today by the National Archives of Australia confirm this.

While the Howard government had many other important issues to manage in that year, the Iraq War consumed most attention and sparked most debate in the wider community.

Entering the war

Cabinet’s National Security Committee had been closely monitoring Iraq and its possible possession of weapons of mass destruction. But in March 2003, Prime Minister John Howard asked the full cabinet to confirm the decision to commit Australia to war.

Despite US urging, the UN Security Council failed to authorise the use of force. It preferred instead to exhaust all opportunities for diplomacy.

On March 18, Howard informed his cabinet colleagues that US President George W. Bush had given Iraqi President Saddam Hussein an ultimatum. Australia was asked to support the United States if Iraq did not fully comply with Bush’s demands.

In the absence of explicit Security Council authorisation, Howard relied for legal justification on a memorandum of advice, signed by two officials at the level of first assistant secretary from the Department of Foreign Affairs and Trade and the Attorney-General’s Department. Iraq, the memorandum argued, had not complied with earlier Security Council resolutions on weapons of mass destruction. Consequently, Australian participation in military intervention would be legal.

Gavan Griffith, Australia’s solicitor-general from 1984-1997, regarded the legal advice as “untenable” and “Alice in Wonderland nonsense”.

The memorandum was nonetheless important for persuading public opinion. Governor-General Peter Hollingworth had earlier asked to see legal advice from the attorney-general, perhaps assuming the decision would be his, acting on advice from the government. Howard advised Hollingworth there was no need to refer to the governor-general any decision to commit Australia to war.

The Howard government instead proceeded with the defence minister using his legal powers under the Defence Act as amended in 1975. This alleviated any need for the attorney-general to provide legal advice to the governor-general, as Sir John Kerr had demanded of the Fraser government in 1977 in regard to appointing the head of the Department of the Special Trade Negotiator, for which Howard was the responsible minister.

The cabinet minute of March 18 2003 smoothed the legal and constitutional difficulties. The attorney-general, it read, agreed with the memorandum submitted by the first assistant secretaries. The governor-general had been consulted but did not need to give his approval, and cabinet had agreed to send Australian troops to war.

Proceeding without a cabinet submission enabled Howard to dispense with advice to cabinet on four other matters.

One was the circumstantial nature of the intelligence used to justify the invasion.

Another was the sectarian chaos that could have been predicted to follow in Iraq.

A third was the danger of military intervention empowering Iran.

A fourth was the consequences for the Australian-United States alliance. Any decision to rebuff Bush’s request would have been treated coldly by his administration. Howard was determined to take advantage of the Iraq war to strengthen the alliance.

Another middle power and NATO ally, Canada, demonstrated its independence without incurring Washington’s enduring resentment. Prime Minister Jean Chretien insisted Canada would not join in military action without United Nations authorisation. The leader of the Labor opposition, Simon Crean, eventually adopted this position too.

Officials in the Department of Defence and Foreign Affairs and Trade did not regard it as their role to offer strategic advice on matters already decided by ministers. This pattern of policy-making indicated the increasing subordination of the public service to ministers since the 1980s. It also reflected the increasingly presidential view Howard had of the office of prime minister.

In 2003, public opinion was opposed to Australian participation in the war. However, the government was aided by the effusive support of News Corporation papers for its position on the war.

Beyond the war

The release includes many other submissions and decisions. Some relate to negotiation of a free trade agreement with the United States.

Ten years after the agreement came into force, however, analysis showed it had diverted trade away from the lowest-cost sources. The Pharmaceutical Benefits Scheme was also affected.

Other papers relate to health policy. Howard sought to blunt an effective Labor campaign against the erosion of the rate of bulk-billing under Medicare. Accordingly, Health Minister Kay Patterson introduced a A$900 million package.

“A Fairer Medicare” was highly criticised, including by a Senate inquiry. It described the package as a “decisive step away from the principle of universality that has underpinned Medicare since its inception”.

With the 2004 election looming, Patterson was replaced by Tony Abbott, who later announced a compromise package called Medicare Plus. It achieved more success by including higher reimbursements for doctors and an extended Medicare safety net aimed at addressing out-of-pocket costs.

A decision on the environment is also noteworthy. Howard appointed a committee to devise an affordable long-term plan to reduce Australia’s greenhouse gas emissions. An emissions trading scheme was recommended.

The plan received the backing of the Department of the Prime Minister and Cabinet, as well as that of Treasurer Peter Costello, Industry Minister Ian Macfarlane and Environment Minister David Kemp. In July, the strategy was taken to cabinet but later, after discussions with industry representatives, Howard dumped it.

Years later, in 2006, under pressure from the “millennium drought”, Howard changed his mind and accepted Treasury’s advice to adopt an emissions trading scheme. Howard’s Labor successors, Kevin Rudd and Julia Gillard, implemented the scheme. In 2013, the Abbott government demolished the scheme with the enthusiastic support of business.

Resources boom – and missed opportunities

In October 2003, the leaders of the United States and China both visited Australia. This offered hope Australia could maintain a constructive relationship with its closest ally as well as its major trading partner.

By 2003, Australia was on the cusp of one its greatest resource booms, fuelled by Chinese demand. The boom gave the government space to turn its attention to a range of reforms in areas such as defence, health, communications and education policy.

Three opportunities were missed in 2003.

One was to establish a sovereign wealth fund to invest the temporary windfall gains from the mining boom.

A second was to establish an emissions trading scheme.

A third was to advance progress on constitutional recognition of Indigenous people.
This had to wait until 2007 when Howard at last recommended a referendum to recognise the role of Aboriginal and Torres Strait Islanders in Australian history.

This year the Australian government is introducing a series of measures to restrict the availability of vapes, starting today.

The new reforms address loopholes in the current laws that allow easy access to highly addictive, flavoured, cheap, and harmful vaping products that are marketed to kids.

Vaping products will still be available through a prescription for anyone using them to quit smoking. But the Therapeutic Goods Administration will tightly regulate prescription-only vapes.

So what are the new regulations? And why are they needed?

Read more:
What’s in vapes? Toxins, heavy metals, maybe radioactive polonium

What was wrong with the previous regulations?

Before the 2024 rule changes, vaping products imported and sold in Australia were required to be nicotine-free, unless accessed through a pharmacy with a prescription from a qualified health professional.

Individual users were also allowed to import nicotine-vapes from overseas through the Personal Importation Scheme, provided they had a valid prescription.

The vaping industry – including manufacturers, importers and retailers – exploited these loopholes and openly sold products containing nicotine to young people by falsely claiming the products were “nicotine-free”.

But the only way to tell the difference between a nicotine and nicotine-free vape is to test it in a lab – a time consuming and expensive endeavour, given the high volume of products imported.

So enforcing the nicotine/nicotine-free standards essentially proved near impossible against an industry determined to addict a new generation of users.

So what’s changing?

The new laws help tidy up the confusion and make the rules much clearer and easier to enforce.

They also address the ready access to vapes, which is the single biggest challenge to preventing young people from vaping.

The regulatory changes will be rolled out in three phases:

1. Importation ban

The first phase, being implemented from today, includes a ban on the importation of all disposable, single-use vapes. These are the products that are most popular with young people and come in a variety of flavours, including fruit, confectionery, cocktails and tobacco.

Single-use, disposable vapes cannot be refilled, but come in a wide range of sizes, from a few hundred of puffs, to upwards of 10,000 puffs.

Disposable vapes have flooded into Australia and fuelled the explosive rise in vape use among teens and young adults.

The importation of all other vapes, including refillable products, will be banned from March 1 2024, unless importers hold a licence and permit from the Office of Drug Control to lawfully import vapes. These legally imported vapes will only be sold in pharmacies to users with a prescription.

The Personal Importation Scheme allowance for vapes will also end on March 1 2024, meaning all vape users must access vaping products from a pharmacy in Australia.

TGA review strengthens case for much tighter vape restrictions at the border

This initial phase, while effectively stopping illegal vapes from coming in to Australia, doesn’t address the high volume of product that is already here. Retailers will be able to continue to sell their existing stock of “nicotine-free” vapes. But as we know, these products often do contain nicotine.

2. Domestic manufacture and sales ban

The next phase of reforms, expected to come into effect in late 2024, will eliminate the retail sale of all types of vaping products, regardless of their claimed nicotine content.

This second phase will include a ban on the manufacture, supply, advertising and commercial possession of vapes that fall outside of the prescription framework.

These changes will require amendments to the Therapeutic Goods Act 1989, and will likely be introduced in Autumn 2024 for federal Parliament’s consideration, but the exact date is yet to be set.

3. Prescription access

The prescription access to vapes for therapeutic purposes is also being changed to allow access to products that meet a quality standard.

From today, all medical and nurse practitioners will now be able to prescribe therapeutic vapes for quitting smoking or to manage nicotine dependence.

Further changes that strengthen the standards for therapeutic vapes are expected to be made by March 1 2024. For example, prescription vapes will have limits on the amount of nicotine, the types of flavours permitted, and be in standardised medical-style packaging.

What do the changes mean for vape users?

Vapes for therapeutic purposes will continue to be permitted in Australia and more medical professionals will be able to prescribe them. Prior to 2024, only select medical professionals could prescribe vapes (they had to register as an authorised prescriber). This is being widened to ensure the prescription model works as intended.

While vaping products will be available by prescription it’s important to know they remain unapproved medicines that have not been subjected to the same rigorous safety and effectiveness testing as other evidence-based quit smoking aids.

If you’re thinking of quitting smoking (or quitting vaping), get support by talking to your doctor, calling the Quitline (13 7848), or accessing help online.

The Australian and American Veterinary Medical Associations recommend keeping cats indoors because they, and wildlife, will be safer.

However, a boring indoor environment may not meet a cat’s need for mental stimulation. So how can we keep cats indoors in a way that will keep them safe and happy?

When considering animal welfare, the Five Domains Model is a good place to start. The five domains are:

1. nutrition – cats need the right type and amounts of food and water
2. physical environment, including temperature, flooring, noise, light
3. health – injury, disease, impairment
4. behavioural interactions with people and other animals, which includes the ability to exercise agency – choosing to engage, or not, in a particular activity at a given moment
5. mental state, including feelings such as hunger, pain, fear and comfort, which is an overall assessment of the animal’s subjective welfare state.

Keeping a cat indoors denies it the choice of being inside or outside. The sense of control an animal has over its life is an important aspect of its welfare, so how can we compensate for this loss of agency?

Several ways to help meet your cat’s needs are available at various price points. Most help meet the cat’s behavioural needs. Some also touch on other needs like environment or nutrition. All will contribute to your cat’s wellbeing.

Free solutions

If you’re feeling the pinch of the cost-of-living crisis, you can still provide your cat with plenty of enrichment for free, or at very low cost. There are multiple options.

Cat music has some scientific evidence behind it and is available on YouTube. This will help meet their environmental needs.

Puzzle feeders, which you can buy or make yourself. Cats are predators, so they are biologically wired to work for their food. Puzzle feeders can be a good way to help meet this biological need.

These feeders don’t have to be expensive. One homemade example is an egg carton with the cat’s food inside and the lid closed, so the cat must find a way to open the carton to obtain the food.

Start with a simple puzzle, and gradually build to more complex puzzles. Only do puzzle feeding if your cat is a good eater and not underweight, though. This will help meet their nutritional and behavioural needs.

Boxes, which cats love to sit in. This hiding behaviour appears to reduce stress Cats will even sit in boxes that don’t technically exist – such as outlines on a floor. This will help meet their behavioural needs.

Clicker training uses a small noise-making device to indicate that the animal has performed a desired behaviour. While more commonly known for dogs, it can also be used in cats.

Read more:
Why you should train your cat – and how to do it

“Do as I do” training is another option. In this training style, the cat learns to mimic your behaviour, but in a species-appropriate way. For instance, if you stood on your tiptoes and raised your arms, your cat would stand on its hind legs and lift the front paws. This will be good for their behavioural needs.

Playing with a pet cat for at least five minutes at a time has been associated with reduced behaviour problems, so play with them to help meet their needs.

New objects/scents will help meet their environmental needs. Cats enjoy novelty as long as there is also plenty of predictability in their environment. Regularly bringing new things or scents like catnip into your home may be interesting for your cat.

For more ideas about enriching your cat’s life indoors, check out this website.

Moderate outlay

If you’re tightening your belt but still have a little to invest in cat enrichment, there are lots of choices within the $10–$50 range to help meet the cat’s behavioural needs.

Harness walks (perhaps after some patient training) let your cat spend time outdoors in a safe way and get exercise.

Toys that move erratically are preferable to static toys. These can be toys that you move yourself such as a toy mouse that you move around on the floor. The movement may appeal to the cat’s predatory nature.

Puzzle feeders can be made very cheaply (see above), but you can buy one too. It can provide interesting variety for cats, especially after they’ve had some puzzle experience. Again, only do this with cats who are good eaters and are not underweight.

A scratching post should ideally be vertical or inclined, which are generally preferable to horizontal surfaces. Chenille, rope or cardboard appear to be the preferred materials.

Why does my cat pee on the rug? Are they trying to tell me something?

Bougie options

If money is no object, you could consider these pricier options. Both help meet their environmental needs.

Cat shelves make use of vertical space so don’t take up a lot of floor space. They provide cats with elevated places to sit, which they like.

Cat enclosures, or “catios”, are enclosed, outdoor spaces where cats can safely spend time outside. They may increase cats’ quality of life.

Remember, every cat is an individual. What works for some cats may not work for yours. Try preference testing – which require the cat to choose between different options or environments – to figure out your own cat’s favourite things.

Australia has long thought of itself as the lucky country.

Whenever its economy has started to falter, a commodity boom has usually come along to restore prosperity… until in the 1980s, when the rest of the world failed to rescue us, and we embarked on a decade of reform.

I am afraid the world is going to fail to come to our rescue once again, and this time it’ll be harder to get a boost from reform because the easy reforms have already been done.

Here’s how I see our history from the earliest days of colonisation.

Exports kept making Australia rich

For most of those two or so centuries, we have been a commodity exporter, at first specialising in wool and wheat (mainly for the United Kingdom) and later specialising in minerals (initially for Japan).

We had to shift our focus quickly when the United Kingdom joined the European Economic Community in 1973.

Fortunately for us, Japan had surpassed the United Kingdom as our biggest customer the year before, in 1972, as our exports of minerals built steadily following the Australia-Japan Commerce Agreement signed in 1957.

Taiwan and South Korea later emulated Japan, buying our coal, iron ore and bauxite to modernise their cities as well as for manufacturing.

Demand for these commodities kept building until the late 1970s when it slowed as the East Asian economies matured.

Then came economic reform, and China

Demand stayed subdued throughout the 1980s and 1990s as Australia got on with economic reform, boosting the economy by letting in foreign banks, floating the dollar, cutting tariffs, removing cosy regulations and privatising enterprises in fields as diverse as airlines, airports, banking, telecommunications and energy.

By the early 2000s, China was a member of the World Trade Organisation and began demanding Australian iron ore and later coal and education, and the old pattern of commodity booms repeated itself, except this time bigger.

The usual pattern is growth in demand for Australian resources followed by a boom in foreign investment to develop those resources that pushes up the value of the dollar and boosts Australia’s buying power but makes its other exports less competitive.

When demand for resources falls, as is about to happen as China’s economy matures, Australians need to tighten their belts.

That’s unless Australia can find another big market or unleash another wave of economic reform.

China’s population is now inexorably shrinking, bringing forward the day the planet’s population turns down

China is a hard act to follow

China’s size makes the export boom we have just had hard to repeat. India has the population and an infrastructure deficit, but more of its own resources, and a more inward-focused growth strategy.

Indonesia has strong growth prospects, but faces challenges investing in infrastructure at scale in its densely populated chain of islands. And Australia faces competition from other commodity exporters. To keep prices high we need global demand to at least keep pace with potential supply.

Yet the International Monetary Fund is downgrading its global growth forecasts.

Geopolitical tensions, rising populism and protectionist sentiments, high debt levels and rising rates of natural disasters and climate-related disruptions are all downside risks for global growth, and, with this, the demand for commodities.

The one bright spot is the minerals needed for the energy transition, where demand exceeds forecast supply.

But Australia has many competitors in the supply of many of these minerals, and we failed to get a head start on the clean energy approaches to processing that would have given us an early advantage.

We’ll need reforms, but more subtle ones

So what are our options?

The reforms of the Hawke and Keating governments are still with us, but the declining role of government in the production of goods and services and a generally light-handed approach to regulation seems to have failed to prevent a decline in competition and, with it, a decline in economic dynamism.

While some of the government’s own actions might have dampened competition, it is entirely possible that the government’s withdrawal from all sorts of markets might be allowing those markets to become more concentrated.

It might even be that the government needs to change course again and reenter or better regulate some markets in order to force providers to lift their games.

While renationalisations are neither viable nor sensible, the energy transition and the projected growth of the care sector offer opportunities to reconsider the balance between the roles of government and the private sector.

The recently-announced Competition Review chaired by Kerry Schott is a step in the right direction.

The right solutions might be more subtle than those that worked in the 1980s. None of them should be off the table.

There are few things more peaceful and relaxing than a night under the stars. Through the holidays, many people head away from the bright city lights to go camping. They revel in the dark skies, spangled with myriad stars.

As a child, I loved such trips, and they helped cement my passion for the night sky, and for all things space.

One of my great joys as an astronomer is sharing the night sky with people. There is something wondrous about helping people stare at the cosmos through a telescope, getting their first glimpses of the universe’s many wonders. But we can also share and enjoy the night sky just with our own eyes – pointing out the constellations and the planets, or discovering the joys of watching meteor showers.

It is easy to be bitten by the astronomy bug, and a common question I get asked is “how can I get more into stargazing?”. Here are ways to get started in this fascinating and timeless hobby that won’t break the bank.

Learning the night sky

A good place to start if you’re a budding astronomer is to learn your way around the night sky. When I was young, this involved getting hold of a planisphere (a star map, you can make your own here), or a good reference book.

Today, there are countless good apps to help you find your way around the night sky.

A great example of such an app is Stellarium – a planetarium program allowing you to view the night sky from the comfort of your room or to plan an evening’s observing ahead of schedule.

To memorise the night sky, you can try star hopping. Pick out a bright, famous, easy to find constellation, and use it as a guide to help you identify the constellations around it.

Learn one constellation per week, and within a year, you’ll be familiar with most of the constellations visible from your location.

Let’s use Orion as an example. The slider below shows images from Stellarium, with Orion riding high in the sky on a summer’s evening. I’ve added arrows to show how you can use Orion (shown in the centre of the map below) to hop around the summer sky.

To learn the constellations around Orion, your task is relatively straightforward. Head out on a clear, dark summer’s night, and find Orion high to the north. The three stars of Orion’s belt are a fantastic signpost to Orion’s neighbours.

If you follow the line of the belt upwards and to the right, you come to Sirius – the brightest star in the night sky, and the brightest star in Canis Major, the big hunting dog. Carry the line on and curve to the left as you go, and you’ll find Canopus, the second brightest star in the sky.

Now come back to Orion’s belt, and follow its line down and to the left. You’ll come to a V-shaped group of stars, including the bright red Aldebaran. This is the Hyades star cluster (with Aldebaran a foreground interloper), which makes up the head of Taurus, the bull.

Take the line further, and you come to the Pleiades – often known as the Seven Sisters – a beautiful star cluster easily visible to the naked eye.

Back to Orion again. This time, you’re going to draw a line from Rigel (the bright star at the top-left of Orion’s boxy body) through Betelgeuse (the bright red star at the lower-right of the box) and continue it towards the horizon. This takes you to Gemini – the twins.

Just by using Orion as the signpost, you can find your way to a good number of constellations (the cyan line points to Lepus, the hare; the white line to Canis Minor, the little hunting dog).

By star hopping, you’ll slowly but surely learn your way around the night sky until the constellations become familiar friends.

Virtual observing

Looking at the sky with the naked eye is a wonderful thing, but it’s also great to zoom in and see more detail.

What if you don’t have access to binoculars or a telescope of your own? Thankfully, software like Stellarium can give you a fantastic virtual observing experience.

Imagine you want to see Saturn’s rings – a spectacular sight through even a small telescope. You can easily do this with Stellarium. Find Saturn by using the search bar and click on it to bring up the planet’s info.

Click on the cross-hair symbol to “lock on”, then zoom in. The further you zoom in, the more you’ll see. You can even run the clock forwards or backwards to see the planet’s moons move in their orbits, or the tilt of Saturn’s rings changing from our viewpoint over time.

A virtual observing session is as simple as that – just pan around the sky until you find something you want to see, and zoom in.

A hobby best shared

Now, a virtual observing session is great, but it pales compared to the real thing. I’d recommend using planetarium programs like Stellarium to figure out what you want to see, then heading out to look at it with your own eyes.

Astronomy is a wonderful hobby, and one that is best shared. Most towns and cities have their own astronomy clubs, and they’re usually more than happy to welcome guests who want to gaze at the night sky.

I joined my local astronomy society, the West Yorkshire Astronomical Society in the United Kingdom, when I was just eight years old. I owe them so much. The members were incredibly supportive of a young kid with so many questions, and I genuinely believe I would not be where I am today without their help. As a member, I saw firsthand just how fantastic the amateur astronomy community is.

At the society, we had weekly talks on astronomy, given by the club members and visiting astronomers from local universities. We also had regular night sky viewing nights, using the society’s very own telescope – a behemoth the members had built themselves.

People who are passionate about their hobby love nothing more than sharing it with others. The members of astronomical societies are fantastic guides to the night sky, and they often have incredible equipment they’re more than happy to share with you.

Both astronomy clubs and universities often offer public night sky viewing nights, which are the perfect opportunity to peer at the sky through a telescope, with an experienced guide on hand to find the most impressive sights to share.

So, if you want to learn more about the night sky, reach out to your local astronomy society – it could be the start of something very special.

If you want to find a local astronomy group, check out this list. If you’re a member of a group that isn’t listed, please reach out to get them to update the list using the ‘Contact Us’ link.

Sadly, 2023 has been a violent one on the global stage. War broke out between Israel and Hamas in Gaza, leading to the deaths of thousands of Palestinians and hundreds of Israelis, including many children on both sides. And the bitter war between Russia and Ukraine continued with no end in sight.

As a result of the focus on these two conflicts, other countries have dropped off the radar for many people. Some of these nations have been dealing with simmering unrest, however, which could erupt in 2024 and seize the global spotlight.

So, where should we be watching in the coming year? Here are five places where I believe civil conflicts or unrest could worsen and potentially lead to violence.

Myanmar

Myanmar descended into chaos in 2021 when a military coup overthrew the democratically elected government led by Aung San Suu Kyi and sparked widespread civil protests that eventually morphed into an armed resistance.

The country, home to 135 ethnic groups, has rarely known peace. For years before the coup, there was a ongoing, low-grade civil conflict between the military and several minority ethnic groups who have long sought control over natural resources in their regions and independence from the state.

This exploded after the coup as ethnic militia groups joined forces with pro-democracy fighters from the Bamar majority protesting the junta.

Their resistance escalated in late 2023 with a coordinated northern offensive dealing the military its most significant losses in many years.

Insurgents won control of towns and villages on the northeastern border with China, including control over key trade routes. This led to renewed fighting in western Rakhine state, as well as in other areas.

The tenacity of the resistance of these minority groups, paired with the refusal of the military to compromise, suggests the country’s civil war may worsen considerably in 2024 and regain international attention.

Mali

In Mali, a nation in the turbulent Sahel region of Africa, tensions escalated throughout 2023 and now threaten to erupt into full-scale civil war.

Mali has long battled insurgent activity. In 2012, Mali’s government fell in a coup and Tuareg rebels, backed by Islamist militants, seized power in the north.

A United Nations peacekeeping mission was established in 2013 to bring stability to Mali. Then, in 2015, key rebel groups signed a peace agreement with the Mali government.

Mali crisis: UN peacekeepers are leaving after 10 years – what’s needed for a smooth transition

After two more coups in 2020 and 2021, military officers consolidated their power and said they would restore the state’s full territorial control over all of Mali. The regime insisted the UN peacekeeping mission withdraw from the country, which it did in June 2023. Subsequently, violence broke out between the military and rebel forces over future use of the UN bases.

In November, the military, reportedly backed by Russia’s Wagner Group, took control of the strategic northern town of Kidal which had been held by Tuareg forces since 2012. This undermines the fragile peace that has held since 2015.

It is unlikely the military will regain complete control over all rebel-held areas in the north. At the same time, insurgents are emboldened. With the 2015 peace agreement now all but dead, we can expect increased volatility in 2024.

Lebanon

In 2019, widespread civil protest broke out in Lebanon against leaders who were perceived not to be addressing the day-to-day needs of the population.

The situation continued to deteriorate, with a reshuffled government, escalating economic crisis and a massive port explosion that exposed corrupt practices.

The International Monetary Fund criticised Lebanon in September for a lack of economic reform. The Lebanese government has also failed to reach agreement on appointing a president, a post that has been vacant for more than a year.

This risks undermining the fragile power-sharing arrangement in Lebanon in which the key political posts of prime minister, speaker and president are allocated to a Sunni-Muslim, Shia-Muslim and Christian Maronite, respectively.

Most recently, the war between Israel and Hamas has threatened to spill over to Lebanon, home to the Hezbollah militant group, which claims to have an army of 100,000 fighters. Importantly, this jeopardises tourism as a key hope for Lebanon’s economic recovery.

These factors may precipitate a more serious economic and political collapse in 2024.

Pakistan

Since Pakistan’s independence in 1947, the military has played an interventionist role in politics. Though Pakistani leaders are popularly elected, military officials have at times removed them from power.

In 2022, Pakistani Prime Minister Imran Khan fell out of favour with Pakistan’s militant leaders. He was subsequently ousted from power in a parliament vote and later arrested on charges that his supporters claim are politically motivated.

Violent demonstrations broke out nationwide after his arrest – a display of anger against the military that was once unthinkable.

Pakistan also faces spillover from instability in neighbouring Afghanistan and increased terror attacks. These security challenges have been compounded by a struggling economy and ongoing costs from the devastating 2022 floods.

Pakistan is expected to hold parliamentary elections in February 2024, after which the current military caretaker government is expected to transfer power back to civilian rule. Many are watching the military closely. If this transfer of power does not take place, or there are delays, civil unrest may result.

Sri Lanka

Sri Lanka faced a debilitating economic crisis in 2022 that led to critical fuel, food and medical shortages. Civil protests caused then-President Gotabaya Rajapaksa to flee the country. He was quickly replaced by current President Ranil Wickremesingh.

Stability returned in 2023 as Sri Lanka began implementing economic reforms as part of a bailout agreement with the International Monetary Fund. However, widespread dissatisfaction with political elites and the underlying drivers of the country’s economic hardship have not been addressed.

Elections are also due in Sri Lanka by late 2024. While Wickremesingh, the incumbent, is likely to run for a second term, he has low trust with the public. He is viewed as too close to corrupt political elites.

This dissatisfaction could lead to renewed protests – particularly if the economy stumbles again – in a repeat of the situation that led to Rajapaksa’s ousting in 2022.

Do you hate salad? It’s OK if you do, there are plenty of foods in the world, and lots of different ways to prepare them.

But given almost all of us don’t eat enough vegetables, even though most of us (81%) know eating more vegetables is a simple way to improve our health, you might want to try.

If this idea makes you miserable, fear not, with time and a little effort you can make friends with salad.

Feeling bloated, hungry or bored after salad? These tips might help

Why don’t I like salads?

It’s an unfortunate quirk of evolution that vegetables are so good for us but they aren’t all immediately tasty to all of us. We have evolved to enjoy the sweet or umami (savoury) taste of higher energy foods, because starvation is a more immediate risk than long-term health.

Vegetables aren’t particularly high energy but they are jam-packed with dietary fibre, vitamins and minerals, and health-promoting compounds called bioactives.

Those bioactives are part of the reason vegetables taste bitter. Plant bioactives, also called phytonutrients, are made by plants to protect themselves against environmental stress and predators. The very things that make plant foods bitter, are the things that make them good for us.

Unfortunately, bitter taste evolved to protect us from poisons, and possibly from over-eating one single plant food. So in a way, plant foods can taste like poison.

For some of us, this bitter sensing is particularly acute, and for others it isn’t so bad. This is partly due to our genes. Humans have at least 25 different receptors that detect bitterness, and we each have our own genetic combinations. So some people really, really taste some bitter compounds while others can barely detect them.

This means we don’t all have the same starting point when it comes to interacting with salads and veggies. So be patient with yourself. But the steps toward learning to like salads and veggies are the same regardless of your starting point.

We’re told to ‘eat a rainbow’ of fruit and vegetables. Here’s what each colour does in our body

It takes time

We can train our tastes because our genes and our receptors aren’t the end of the story. Repeat exposures to bitter foods can help us adapt over time. Repeat exposures help our brain learn that bitter vegetables aren’t posions.

And as we change what we eat, the enzymes and other proteins in our saliva change too. This changes how different compounds in food are broken down and detected by our taste buds. How exactly this works isn’t clear, but it’s similar to other behavioural cognitive training.

Food as medicine: why do we need to eat so many vegetables and what does a serve actually look like?

Add masking ingredients

The good news is we can use lots of great strategies to mask the bitterness of vegetables, and this positively reinforces our taste training.

Salt and fat can reduce the perception of bitterness, so adding seasoning and dressing can help make salads taste better instantly. You are probably thinking, “but don’t we need to reduce our salt and fat intake?” – yes, but you will get more nutritional bang-for-buck by reducing those in discretionary foods like cakes, biscuits, chips and desserts, not by trying to avoid them with your vegetables.

Adding heat with chillies or pepper can also help by acting as a decoy to the bitterness. Adding fruits to salads adds sweetness and juiciness, this can help improve the overall flavour and texture balance, increasing enjoyment.

Pairing foods you are learning to like with foods you already like can also help.

The options for salads are almost endless, if you don’t like the standard garden salad you were raised on, that’s OK, keep experimenting.

Experimenting with texture (for example chopping vegetables smaller or chunkier) can also help in finding your salad loves.

Read more:
Frozen, canned or fermented: when you can’t shop often for fresh vegetables, what are the best alternatives?

Challenge your biases

Challenging your biases can also help the salad situation. A phenomenon called the “unhealthy-tasty intuition” makes us assume tasty foods aren’t good for us, and that healthy foods will taste bad. Shaking that assumption off can help you enjoy your vegetables more.

When researchers labelled vegetables with taste-focused labels, priming subjects for an enjoyable taste, they were more likely to enjoy them compared to when they were told how healthy they were.

The bottom line

Vegetables are good for us, but we need to be patient and kind with ourselves when we start trying to eat more.

Try working with biology and brain, and not against them.

And hold back from judging yourself or other people if they don’t like the salads you do. We are all on a different point of our taste-training journey.

The recently concluded men’s Cricket World Cup in India reached record audiences. But there was one thing the organisers did not want those viewers to see (other than India’s defeat by Australia in the final): cricket’s own climate crisis.

Along with battling heat and humidity, players were forced to contend with unhealthy air created by pollutants from vehicles, factories and construction, and aggravated by increased temperatures in 20 of the 47 matches.

As Indian captain Rohit Sharma remarked, “It is not ideal and everyone knows that.”

The United Nations describes the threat more forcefully. Secretary-General António Guterres has warned the world is on a “catastrophic path” to a “hellish future”. It is a future that threatens the very viability of cricket.

Cricket and the climate Crisis

As an outdoor summer game in which the natural environment plays a unique role, cricket is perhaps the pitch sport most at risk from a changing climate.

Increased temperatures and heat waves threaten the safety of players and spectators, as well as the preparation and maintenance of playing surfaces.

Equally, cricket is vulnerable to higher risks of drought and flooding. Air pollution, especially in the Indian subcontinent, continues to cloud the game.

Time for a reckoning: Cricket Australia, fossil fuel sponsorship and climate change

The threat is compounded by the precarious regions in which cricket is played. Bangladesh and Pakistan – where New Zealand’s Black Caps played their past two overseas Test series – are ranked seventh and eighth respectively for vulnerability on the Climate Risk Index.

At the same time, cricket is not merely a potential victim of the climate crisis, it is a contributor to it.

While it lags behind other sports in calculating its environmental impact, cricket is a resource-heavy game. Preparation of a cricket field requires around 60,000 litres of water a day. An expanding international touring schedule means regular long-haul flights.

One of the few existing studies estimated an Indian Premier League match produced about 10,000 tonnes of carbon dioxide. Overall, cricket’s carbon footprint is substantial.

Sport and Sustainability

For a game facing a potential existential crisis, cricket’s sustainability efforts have been slow by comparison with other sports.

In line with the Paris Agreement, the International Olympic Committee has committed to a 50% reduction in direct and indirect carbon emissions by 2030, and promised the 2032 Brisbane Olympics will be “climate positive”.

Both FIFA and World Rugby have sustainability plans, as do Formula One and most American sports leagues, including the NBA. Sail GP even has an “Impact League” that measures environmental mitigation efforts.

Rising costs of climate change threaten to make skiing a less diverse, even more exclusive sport

While some scepticism might be warranted – FIFA held a World Cup in oil-rich Qatar, and the 2030 men’s tournament will be held across two continents – at least the intent is clear.

By contrast, the International Cricket Council has not published a sustainability strategy. Of its full members, only the England and Wales Cricket Board has such a plan.

Of the more than 200 sporting organisations to sign up to the UN’s Sports for Climate Action Framework – which requires participants to halve emissions by 2030 and reach net zero by 2040 – only six are cricketing entities, and most are in England.

Inaction in New Zealand

New Zealand Cricket (NZC) is as silent on climate as many of its global counterparts. Environmental sustainability does not appear in NZC strategy documents.

At the same time, its 2022-23 annual report laments that less than half of all scheduled recreational fixtures could be played in some areas due to rain and flooding. It also notes the “cyclones, floods and related civil emergencies” that caused these cancellations were “well beyond its control”.

New Zealand’s 2023-24 cricket season could be the hottest yet. Following the devastating floods in Auckland in early 2023, a drought is possible this summer. Heat waves are becoming more persistent and more dangerous.

Cricket is not made for such extremes. At a time when game is struggling to attract participants, climate change is making it harder for recreational cricketers to play.

New Zealand Cricket’s mission statement states:

We think ahead and pay it forward. It’s about doing the right things for the best reasons. Leading the way, and following our own path. We never give up, give in, or say die.

It may be time to apply those admirable sentiments to its response to the climate crisis. The first step would be to sign up to the UN Sport for Climate Action Framework – and get some sustainability runs on the board.

First Nations people please be advised this article speaks of racially discriminating moments in history, including the distress and death of First Nations people.

On October 9 1873, George Augustus Frederick Dalrymple reclined in a boat on the glorious North Johnstone River in the coastal Wet Tropics. Dalrymple was in raptures. A riot of palms, bananas, ferns and lilies descended to the waters edge, and large-leafed taro grew in strips along the riverbank over tens of hectares. He came across a large village with rows of neatly made bark and palm leaf huts. Dappled paths led to managed patches of open forest, groves of fruit trees, bananas and yams. Nearby, a small fleet of moored catamarans sat bobbing.

In the colonial literature, there are many such descriptions of beautiful and bountiful pre-European tropical landscapes. It was clear that people had helped create such a rich paradise through their land management

By 1886, many rainforest people of tropical north Queensland had been “dispersed” – killed – and swathes of this biodiversity hotspot began being cleared for sugarcane.

First Nations groups such as Australia’s rainforest people had skilfully managed entire ecosystems over the long term, in what has been termed “ecology on steroids”. These future-making methods protected landscapes from climate change and buffered them against extinction.

Australia’s First Nations did this through the cold and dryness of the last ice age, and as the seas rose through the droughts and floods of the El Niño Southern Oscillation climate cycle.

As we face an uncertain climate future, it’s valuable to look at how people weathered such change.

Decoupling landscape from climate change

When people first came to Australia, the Wet Tropics were not wet. The Pleistocene climate was cool and windy, with mega monsoons and long periods of diabolical drought. If you had looked east from what is now Cairns, you would have seen not oceans and coral atolls, but plains and valleys filled with grasslands and forest. The sea lay tens of kilometres off the continental shelf.

The oldest record of human occupation in Australia is found in the Top End. Here, in a magnificent cave system in Arnhem Land, people prepared a meal of native fruits and processed pandanus using an adaptable toolkit. This meal took place 65,000 years ago, when savannah stretched all the way to the island of New Guinea.

Over thousands of years, Australia’s people developed a vibrant cosmology. For First Nations people Country was sentient. The land was not a mindless resource but part of your family – and came with family obligations. Everyone, whether you were human, an animal, a plant, a river, fire, the sky or wind, was closely watched. People were embedded within ecosystems.

Recently scientists sampled the deep mud of Girraween lagoon in the Top End searching for pollen and charcoal that would provide a window into this deep time.

Some 13,000 years ago, the landscape was parched. But as the northern hemisphere ice sheets melted, the seas rose and the monsoons began to return. By the mid-Holocene, between 9,000 and 4,000 years ago, the monsoons were arriving regularly. The lagoon filled up, nestled in a landscape of moisture-loving shrubs and brushed by relatively cool fires.

But then, the climate lurched to one of the long periods of horrendous drought instigated by an El Nino weather system.

Curiously, destructive fires did not follow. The deep mud core showed fire became less, not more, intense, as the forest shaded out the volatile grasses that cause intense fires in savanna. Even as drought increased, the Top End landscape filled with layers of diverse herbs and shrubs, with a variety of trees and groves of monsoon forest closer to the lagoon.

This patterning was likely the handiwork of people taming fire and putting it to work. Through patch burning, they created a rich landscape of diverse habitat that sustained people and created niches for a wide range of species.

Today, a quarter of Australia’s fire-prone savannahs, mostly managed by First Nations peoples, are returning to patchy fire regimes. These reduce the big wildfires associated with European pastoralism and reduce emissions.

Extinction busters

Perhaps few places encapsulate the harshness of Australia’s environment more than the Great Sandy Desert. From before the last ice age, the ancestors of today’s Martu people would have witnessed great floods rushing down the Sturt Creek into an extensive lake system, Paruku (Lake Gregory). These lakes were ten times larger than today’s system, ringed by dunes covered in scrubby vegetation and flammable spinifex.

Over perhaps 50 millennia, the Martu used fire to create mosaic landscapes.

In the 1960s, the Martu were forced to leave to make way for nuclear missile tests. Without cultural burning, it took mere years for fuel to build up and large wildfires to incinerate the landscape.

You can see the change clearly. Satellite images and aerial photograhy showed the size of the average fire went from 64 hectares under Martu management to over 50,000 ha by the 1980s.

In turn, this drove dramatic shifts to the food web. Over the two decades of Martu absence, ten species of small mammal became locally extinct, including the rufous hare-wallaby, burrowing bettong, bilby, mulgara and brushtail possum. What’s more, 14 mammals, three birds and two reptiles became threatened. Cats, foxes, camels and buffel grass became widespread.

In the 1980s, the Martu were able to return. Back on Country, they worked with scientists to reconstruct pre-1960s food webs from their memories, recalling not only species hunted, but rich detail of the behaviour, interactions and life histories.

Today, Indigenous Protected Areas covering millions of hectares have been added to the national estate. The Western Desert Martu Ranger program manage 6.5 million hectares.

This return to First Nations management is long overdue, as human-made climate change intensifies. We will need to relearn these ancient techniques of managing country on a broader scale to cope with the changes to come.

Imagine the dentist has just said you urgently need a A$2,000 dental crown. A week later, a pipe in your bathroom bursts, causing $8,000 worth of damage. Suddenly, you’ve been hit with a $10,000 financial shock.

As the cost-of-living crisis plunges more households into financial uncertainty and at least one-third of Australians struggle to make ends meet, it’s more important than ever to ask yourself: how financially resilient am I?

Being financially resilient means you aren’t left financially devastated when an expensive emergency creeps up on you. Here are five key signs of financial resilience.

Read more:
Kids and money: five ways to start the conversation

1. You have a plan for what you’d do if you suddenly lost your salary

Financial resilience means having a plan to fall back on during tough times. This extends to how you’d make money if you lost your job.

In practice, that means things like making sure your skills and contacts are kept up to date so you can more easily find a new job. You might also consider whether a “side hustle” job such as tutoring could work for you in the short term, and how you’d put that plan into practice if needed. Perhaps you have a spare room in your home you could rent out for a period of time if you lost your salary.

Those examples won’t work for everyone, of course, but it’s still worth asking yourself the question: what would I do if I lost my salary tomorrow?

2. You have enough liquid assets to meet an unexpected financial expense

Liquid assets means money that can be accessed quickly and easily to overcome an unplanned financial expense. Savings are a good example. They provide a buffer so you can cope in the short term if a financial shock strikes. The federal government’s Moneysmart website suggests you aim to have enough in your emergency savings fund to cover three months of expenses.

Having an offset account as part of a mortgage is another option that provides a buffer. Putting money in an offset account helps you save while reducing the amount of interest on a home loan. You can still access the money in an offset account at any time.

3. You have bought the right financial products, such as insurance

Financial products, such as insurance, hedge against potential losses.

Personal insurance is important because it provides income in the event of death, illness or injury. Examples include:

• life insurance (which pays out to your beneficiaries, such as your partner or children, when you die)

• total and permanent disability insurance (which means you may get some money if you acquire a disability that prevents you from working)

• income protection (which provides you with an income if you can no longer work)

• trauma cover (which covers a life-changing illness or injury, such as cancer or a stroke).

Check if your superannuation has any of these insurances included in it. Research has found that many Australians are underinsured.

4. You can still pay your debts when times are tough

Being able to borrow money can help when you’re in a tight spot. But knowing where to borrow from, how much to borrow and how to manage debt repayments is crucial.

Financially resilient people use debt responsibly. That means:

• not using debt for frivolous expenses like after-work drinks

• staying away from private money lenders

• being cautious about buy-now-pay-later services

• watching out for debts with high interest rates, such as payday loans and credit card debt

• maintaining debt repayments consistently.

If you’re having debt problems, talk to your lender about renegotiating your repayment arrangements, or contact the National Debt Helpline on 1800 007 007.

5. You are financially literate

Being financially literate means you can assess the benefits and risks of using savings or taking out debt to meet an unplanned financial need.

As I have written before on The Conversation, key signs of financial literacy include tracking your cashflow, building a budget, as well as understanding what debts you have and which to pay first.

It also means storing your money across different places (such as superannuation, savings accounts, property and the share market) and understanding how financial assets like cash, shares and bonds work.

Being aware of your financial strengths and weaknesses, and having financial goals is also important.

Nobody is born knowing how to make sound financial decisions; it’s a skill that must be learned.

It’s good to think about the resources you would draw upon to help get yourself out of a difficult financial situation – well before disaster strikes.

I thought convincing my husband of the merits of my returning to study just as he had retired would be a very tricky sell. So his enthusiasm for the idea caught me by surprise.

He helpfully suggested several interesting topics: sea turtles, dugongs and coral reefs. If it involved a boat in a warm climate, he was behind me 100%.

But if you are going to dedicate three and a half years to studying a single topic, it really needs to excite you, and my interest in gut bacteria and health won out. Much to my hubby’s dismay, I chose to immerse myself in the subject of marsupial poo – and in retaliation he started calling me Dr Poo.

Fortunately, I am not alone in my faecal fetish. As any wildlife carer can tell you, monitoring what comes out of an animal is a vital part of keeping an eye on its health.

So when I set out to find volunteers to collect poo from wild and captive marsupials – specifically eastern grey kangaroos, swamp wallabies, red-necked wallabies, bare-nosed wombats, and ringtail and brushtail possums – over an area from Queensland to Tasmania, it was mainly wildlife carers who answered the call.

The Marsupial Microbiome Poop Troop

I enlisted a core group of around 20 people who, every season, dutifully went out in all weathers, armed with their forceps and zip-lock bags, to select fresh pellets from their in-care residents or wild animals that passed through. Then they filled in the paperwork, carefully labelled the bags and stored them in freezers until they could be posted in special temperature-controlled packaging to the university for genetic analysis.

We did this to establish a baseline of what the normal wild gut microbiome looks like in different animals in different areas at different times of the year. This lets us recognise if there is an imbalance in captive animals that can be addressed and prevented by changing diet or introducing supplements.

To aid my communication with these wonderful volunteers, I started a Facebook group page which became known as the Marsupial Microbiome Poop Troop. And it has some colourful members.

There is Kate, who obtains the freshest wombat poo by stalking wild wombats in her local reserve until they produce the goods. Don’t try this at home. Kate has serious wombat-whisperer skills.

What can you learn from studying an animal’s scat?

There’s Darryl, who was devastated when the roof blew off his house in a storm and he was without power for two weeks. Not for his wrecked house or loss of possessions, but because his collection of possum poo thawed and he had to throw it away and start again.

Julie wins the prize for most prolific collector. Her poo parcels are the largest by far, and cover quite a few species. The supervisor of the university’s stores, who receives the poo parcels, is not always a fan of Julie’s efforts. He must have highly attuned olfactory senses as he routinely sends me emails announcing the arrival of more “animal excrement” or “malodorous packages” for immediate collection.

Saving orphaned joeys

While it all sounds like fun and games, the research we do with the collected poo has serious potential to save many marsupial lives. We have a particular focus on young orphaned joeys.

Whether their mothers were hit by cars, attacked by dogs, or died of other causes, the joeys arrive at wildlife shelters stressed, often injured, and generally cold and hungry. Because marsupials are born so undeveloped – and normally spend a long time in their mother’s pouch – they require an extended period in care when orphaned.

The gut microbiome of these “pinky” joeys is equivalent in development to that of premature human babies. It is still being established at this crucial time, via the mother’s milk, environmental conditions in the pouch, cleaning and grooming.

The sudden loss of parental care, coupled with the stress of being in captivity and a complete change of diet, can do a great deal of harm to the gut microbiota. This can leave the joey open to infections, diarrhoea and dehydration, which can be fatal.

If it were possible to fix this imbalance, the success rate of rearing orphaned marsupials would rise. Their improved general health should mean greater numbers of animals successfully reintroduced to the wild.

From the frontline: saving Australia’s threatened mammals

While the animals involved in this study are considered “common”, the same principles may be applied to endangered species held in captive breeding programmes once it has been shown to work on the more prolific species.

Without the help of the Poop Troop volunteers, it would have been impossible to sample so widely and consistently. The remaining poo will be kept frozen and made available to future researchers, so these wonderful people have, through their dedication and persistence, made a real contribution to marsupial microbiome research that will continue to help wildlife in the future.

New Zealand consistently ranks well in global monitors of democracy, media freedom and open government. But high rates of abuse and threats directed at journalists put us at risk of “mob censorship” – citizen vigilantism that seeks to discipline journalism.

Our recently published study documents newsworkers’ experiences of abuse and violence at New Zealand’s largest news organisation, Stuff.

The research reveals just how widespread online and physical abuse towards journalists has become – and how this is changing the news and who is covering it.

A ‘festering heap of toxicity’

Not one of the 128 journalists and visual journalists surveyed was untouched by abuse, threats or violence related to their job, most commonly delivered via work email on a daily or weekly basis. One respondent described her inbox as a “festering heap of toxicity”.

Women journalists bear the brunt of online abuse, primarily related to their gender or ethnicity (53%) and physical appearance (32%) (such as “ugly bitch” or “Pakeha ugly c***”), compared with 20% of men.

Attempts to discredit them were also reported by 45% of women as opposed to 34% of men. All threats of sexual violence captured in our survey were made towards women.

Overall, men tended to experience more “offline” threats (44% compared to 23% of women) and actual physical violence (16% men compared to 12% women). Nearly 40% of all those experiencing physical violence were visual journalists, showing up to photograph emotionally-charged events such as accidents and protests.

When we further analysed our findings by ethnicity, it was our small subset of Māori women who reported the very highest rates of offline threats and actual violence. These journalists represented the intersection of both gender and ethnicity – increasing their likelihood of being a target of abuse.

Targets for writing about race

As well as capturing the high levels of abuse and threats directed at Māori women journalists, our survey documented ways in which the content of news itself was at risk from mob censorship.

Simply writing stories about race or racism triggered abuse for the writer, whatever their actual or perceived identity.

A self-described “white-passing Māori” explained how, after reporting on the dawn raid apology, she received messages calling her things like “white apologist bitch”. Several Pākeha women were abused as racists or traitors for using te reo Māori in stories or writing about racism.

While a handful of male journalists reported abuse in the vein of “pale, stale, male” – an equally unhelpful development – it was much more common for male respondents to observe greater levels of abuse directed at female colleagues for writing similar stories.

Campaign trail threats and abuse reinforce the need to protect NZ’s women politicians – before they quit for good

Extensive and detailed reports of gendered abuse provide clear evidence that simply being female puts women journalists at risk in New Zealand, as it does elsewhere.

One participant wrote that “comments about being female are pretty much the common thread of all toxic messages I’ve received” – a pattern that Stuff journalist Michelle Duff has argued was “designed to silence”.

Several women said they turn down opportunities to write opinion pieces. As one said, “I just cannot believe the feedback women get if you express any opinion”.

Similar patterns have been documented by journalist Charlotte Graham McLay. Unsurprisingly, a good proportion of women journalists (22%) contemplated leaving the profession, compared to 4% of men.

But abuse affects all journalists, at least indirectly. Some 71% of our participants adjusted their online behaviours, including closing social media accounts, and 24% indicated they had consciously altered a story. As one person said, “there are [controversial or divisive] stories I’d be less likely to pursue”, including to protect vulnerable sources.

Accepting abuse is not the answer

More than three-quarters of our respondents considered abuse and threats to be just part of the job. There was, though, concern this feeds a “dangerous” and “outdated” professional culture that shuts down frank discussion and causes anxiety.

One female reporter who had experienced on-the-job violence wrote of being “extremely worried” that she or a colleague “will eventually be singled out by an extremist to be attacked or killed”.

Online attacks on female journalists are increasingly spilling into the ‘real world’ – new research

Some journalists in our study saw value in responding to abusive emails from readers. As one respondent said, “once I engage with someone (generally) they are apologetic and start interacting like a normal human being”, and exchanges “have morphed into positive experiences for both parties”.

But this emotional labour is an additional burden in under-resourced newsrooms.

Furthermore, some participants were sceptical about the extent of employer commitment to addressing the problem, given the adoption of branding practices such as publishing photo bylines and email addresses, which tended to ramp up online abuse.

Muted watchdogs

Globally, the news industry hasn’t done a good job of training, supporting and protecting its journalists in the digital era.

Research from the United States suggests that receiving regular abuse entrenches journalists’ “us versus them” mentality. This deepens the rift between news organisations and the communities they serve, fuelling mistrust.

Clearly, democracy itself is undermined by any intimidation or disincentive that stops journalists from performing their watchdog duties.

Supporting journalists to do their jobs as safely and free from abuse as possible needs to be the industry’s top priority for 2024. It’s vital not only for them, but also for our democratic future.

More of us have tattoos than ever before. About 25% of Australians are inked.

A tattoo can be a large investment in time, money and pain.

So how do you take care of your tattooed skin? Here’s what you need to know about sunburn, sweating and fading.

Tattoos have a long history going back to the ancient world – and also to colonialism

What’s a tattoo, dermatologically speaking?

Tattoo inks are deposited in the layer of skin called the dermis. This layer contains sweat and oil glands, a blood supply, immune cells, collagen to support the skin’s structures, and fibroblasts, which produce collagen.

Fibroblasts take up the ink particles, as do immune cells in the dermal tissue known as macrophages. The ink particles also stick inside bundles of collagen.

Between these three mechanisms, the dermis holds tattoo inks so well they can be seen even on the 5,300-year-old ice mummy Ötzi.

Can I get a tattoo if I’m sunburnt?

No, and many tattoo artists will not do it. During sunburn, your skin calls in extra immune cells and fluid to kill off and break down cells that have too much UV damage.

This inflammation can affect the tattoo ink deposits. You might not get the look you were after, with too much ink removed by your immune cells or swelling distorting the lines.

It’s much better to be proactive about sun protection before a tattoo, or at least be patient and reschedule when your skin has healed.

How soon after my new tattoo can I go into the sun?

There’s not much research on how soon you can expose your new tattoo to the sun. However, most tattooists advise you to avoid sun exposure while the tattoo heals, generally about three weeks.

This seems sensible, as your fresh tattoo is a type of wound.

Because the skin is damaged by inserting a needle, it’s not too surprising that the most common short-term complication is local inflammation with swelling, redness and discomfort at the tattoo site. There is an influx of immune cells to deal with the damage, much like a sunburn.

So, in one way, you should treat your new tattoo like sunburn and avoid sun exposure while it heals.

But you shouldn’t use sunscreen on the tattoo in that time. That’s because sunscreen can enter the dermis through the puncture wounds and cause more irritation. Cover your new tattoo with loose clothing instead.

What happens if my tattoo gets sunburnt?

Sunlight-induced reactions to both new and existing tattoos are common. There’s usually swelling, itching or stinging on the tattoo site that can start immediately or develop over the course of a day. We’re not really sure why this happens.

Most of the time, these reactions are unpleasant but don’t require medical treatment, much like sunburn.

There is also a small amount of evidence that sunburn on a tattoo temporarily suppresses the skin’s immune system, allowing an infection to become established.

Do tattoos increase my risk of skin cancer?

Some ink components, such as mercury or carbon black, are suspected cancer-causing agents when used in other applications. However, there’s no evidence skin cancers are more likely in tattooed skin.

Tattoos make newly-developed skin cancers more difficult to detect. Besides making the lesion more difficult to spot in the first place, the colours of the tattoo interfere with your doctor’s assessment of the colours in the lesion, which can be an important sign of cancer.

So it’s a good idea to get familiar with the moles and freckles on a patch of skin before you’re inked, and check them yourself once a month for changes.

Red tattoos seem to be more prone to large but benign (non-cancerous) skin tumours called keratoacanthomas. These appear within a few months of tattooing, and often grow rapidly but then heal by themselves.

However, they can be difficult to distinguish from squamous cell carcinomas (a type of skin cancer). They can also damage underlying structures, such as nerves and muscles. So they often need to be removed anyway.

Health Check: do I need a skin cancer check?

Can sunlight fade my tattoo?

As tattoos age, they can fade a bit as some of the loose ink particles filter deeper into the dermis. Sun exposure can also degrade ink particles.

There’s limited research on this in human skin. After all, most people don’t want to fade their tattoos for science. So most of what we know is from research in mice.

However, modern tattoo inks give you a strong colour. So in practice, you might not notice any fading for years.

Does tattooed skin sweat differently to un-inked skin?

This is an important question, because sweating is a major way our body avoids overheating in the summer. If you’ve got a full sleeve or your whole back is your canvas, that’s a significant amount of skin.

Since tattooing punctures the skin repeatedly, sweat glands in the dermis may be damaged.

But the research on tattoos’ impact on sweating is mixed and depends on what you are doing at the time.

In one study, researchers used a heatable suit to increase study participants’ internal body temperature by 1°C. Tattooed areas produced about 15% less sweat. It’s not clear if this is enough to increase the risk of heat stress.

However, when other researchers looked at sweating induced by exercise there was no effect in the volume of sweat between tattooed and un-tattooed skin.

Longer-term risks

When performed under the clean conditions of a licenced tattoo parlour, tattooing is relatively safe.

But long term, some people develop allergic reactions to certain colours due to the different compounds in each, most commonly red dyes. This can cause lumps, scales, scarring or other visible changes.

So, what’s the most common long-term side effect of tattoos? Tattoo regret and wanting to have them removed.

When was the last time you saw a frog? Perhaps you came across one in your garden and wondered at its little hands, glossy skin and what looked very much like a contented smile.

Maybe you regularly see them on Instagram or TikTok, where “frog accounts” have proliferated in recent years. People share adorable cartoon frogs, coo over crocheted frogs or go gaga for frogs dressed in cute hats.

In fact, our fascination with frogs isn’t new. As our research has found, the history of human-frog relations is long and complicated – and not all of it is nice.

Australian frogs are dying en masse again, and we need your help to find out why

Why we love frogs

There is a rich history of people really loving frogs.

This is interesting, because many people much prefer mammals and birds over reptiles and amphibians.

But the frog is an exception – for a lot of reasons. People tend to be attracted to baby-like faces. Many species of frog have the large eyes characteristic of young animals, humans included.

Having no teeth and no sharp claws, they also do not seem to be immediately threatening, while many of them have beautiful skin colouring and some are improbably tiny.

Frogs are truly among the jewels of the natural world, unlike toads which – with their more mundane colours and “warty skins” – do not usually inspire the same sense of enchantment.

Their beauty connects us to the wider riches of a vibrant nature hidden from most people’s sight in the dense rainforests of the tropical regions.

And they also connect us to nature in our own backyards. At certain times of the year, they spontaneously appear in our gardens and ponds. They can feel like special visitors from the natural world.

Dissecting human feelings for frogs

Yet relationships between people and frogs haven’t always been so positive. In fact, frogs occupy complicated places across cultures all over the world.

In the Western tradition, the legacy of biblical and classical sources was both negative and longstanding.

References to frogs in the Bible rendered them the instrument of divine anger as a swarming plague.

Frogs challenged early modern zoological taxonomies, moving between classification as serpent, insect or reptile.

Perhaps their resistance to easy placement by humans explains the strong emotional language about them used by Swedish naturalist (and “father of modern taxonomy”) Carl Linnaeus.

When he considered the Amphibia in his 1758 Systema Naturae, he noted:

These foul and loathsome animals are abhorrent because of their cold body, pale colour, cartilaginous skeleton, filthy skin, fierce aspect, calculating eye, offensive smell, harsh voice, squalid habitation, and terrible venom.

In modern science, they sit in a branch of zoology, herpetology, that brings frogs together as “creeping animals” with snakes and lizards.

Frogs have also (or perhaps consequently) suffered in the service of science since at least the eighteenth century because it seemed to be possible to easily replicate experiments across multiple frog specimens.

Frogs were particularly crucial to the study of muscles and nerves. This led to ever more violent encounters between experimenters and frog bodies. Italian scientist Luigi Galvani, for example, did experiments in the late 18th century on legs of frogs to investigate what he thought of as “animal electricity”.

In this sense, frogs were valued as significant scientific objects, their value lying in their flesh, their nervous systems, rather than in their status as living, feeling beings in the world.

In time, experiments with frogs moved beyond the laboratory into the classroom. In the 1930s, schoolchildren were expected to find frogs and bring them to school for dissection in biology classes.

This practice was, however, somewhat controversial, with opponents expressing sentimental attachment to frogs and concerns that such animal cruelty would lead to barbarism.

Recognising the fragility of frogs

So, our relationship with frogs is complicated. From the frogs of Aesop’s Fables to the meme Pepe the Frog, we have projected our own feelings and frustrations onto frogs, and exploited them for science and education.

Frogs have also borne the brunt of our failures as environmental stewards.

By 1990, the world was seeing a global pattern of decline in frog populations due to destruction and degradation of habitat for agriculture and logging, as well as a global amphibian pandemic caused by the chytrid fungus.

Climate change is also making life hard for many species. In 2022, over 40% of amphibian species (of which frogs and toads are by far the largest group) were threatened with extinction. Their vulnerability has seen the frog – especially the red-eyed tree frog – become a symbol for the environment more generally.

So we should delight in frogs and marvel at how beautiful and special they are while we still can, and consider how we might help save them.

Something to reflect on next time you are lucky enough to spot a frog.

As any frequent social media user knows, airline passengers often record and post in-flight incidents – from frightening turbulence to unruly members of the public.

Often, these viral videos feature flight attendants just trying to do their duties, while being filmed without their consent.

These videos usually portray flight attendants either as heroes effortlessly managing difficult passengers or “villains” accused of being rude and unprofessional. Either way, the trend is emerging as an industrial issue, with unions arcing up about it and airlines bringing in new rules aimed at curbing the practice.

Qantas won’t like it, but Australian travellers could be about to get a better deal on flights

Unkind comments about appearance and age

Going to work knowing that at any moment you may become the unwilling star of a viral video can exact a considerable toll on the wellbeing of flight attendants.

I (Liz Simmons) speak daily with flight attendants in Australia and abroad as part of my PhD research. From these discussions, I’ve heard from attendants who worry often about discovering videos of themselves featuring unkind comments about their appearance, age or employer.

One flight attendant, Kate*, described the disconcerting feeling of someone aiming a smartphone camera at her while she was simply trying to do her job, saying:

You don’t know why they’re filming or what they’ll do with it.

Marie spoke of being featured in a TikTok video during a safety demonstration, with viewers making fun of her appearance.

Charlotte, after refusing to serve more alcohol to an intoxicated passenger, had a camera thrust in her face, accompanied by threats to her job.

Mark told of how uncomfortable he felt having to ask a passenger to stop taking photos of the crew during service.

These personal accounts illustrate the distress flight attendants can experience when being filmed or photographed without their knowledge.

A broader industrial issue

This issue is drawing the attention of policymakers, airlines and the unions that represent flight attendants.

Japan recently introduced laws aimed at curbing sneak photography in a range of settings, which may be used to prevent passengers voyeuristically filming flight attendants. Research by Japan’s aviation workers union found that about 70% of the 1,573 flight attendants surveyed believed they’d had their pictures taken surreptitiously while they were working.

Passengers have been arrested in Turkey and India after unauthorised filming.

And flight attendant unions in Japan, Hong Kong and Australia have voiced concerns about the issue.

Of course, videos can occasionally play a crucial role in understanding what transpired during an in-flight incident, and flight attendants themselves can also be found on social media sharing their stories, consenting to the video. But many videos still feature airline staff simply going about their job (while being filmed, without their consent).

Unclear rules

News reports suggest staff aboard Dutch carrier KLM “now commonly make an announcement during the safety briefing asking passengers not to take photos of any crew members.”

The rules on the KLM website are less clear, saying only that

Recording videos and/or taking photographs other than personal videos and photographs is prohibited on board the aircraft.

Virgin Australia’s rules state anyone travelling on their planes must

use cameras or photographic devices (including mobile phones) for personal use only. You must comply with the directions of flight crew when using cameras or photographic devices while on board.

In November 2023, Qantas introduced new rules requiring passengers to

seek consent before filming or photographing Qantas Group staff, contractors or other customers.

This is a start. For most airlines, however, there is a notable absence of clear guidelines against recording and publishing footage of flight attendants in their workplace. The existing rules are often buried in the fine print of terms and conditions, which few passengers take the time to read. This underscores the necessity for airlines to reconsider how these restrictions are communicated to passengers.

Looking ahead, it may be timely for more airlines to establish clearer rules on filming cabin crew while they work. There should be an acknowledgement that unsolicited filming is frequently unfair, invasive and distressing. Developing a framework to enforce these provisions and enhancing communication about these rules would help inform passengers about how to respect the privacy and comfort of flight attendants in their workplace.

In our house we have a favourite story about the time our toddler was dragged from the National Portrait Gallery kicking and screaming “I want to see more paintings!!!”

She needed lunch, we had to go, but she really loved the “Nick Cave Gallery”, as she called it, with his luminous portrait by Howard Arkley on display.

What parenting miracle did we pull off to have a daughter that loves art galleries so much? We have always taken our kids to galleries. It’s what we do for fun and is what they want to do as teenagers. Visiting a new town or city, we check out local art wherever we can find it.

I have a long history of working with galleries and I am a practising artist, so gallery spaces are familiar to us and are meaningful places associated with joy, wonder and celebration. But you don’t need to be an artist to help your kids enjoy a gallery visit.

Four tips to make the most of your next gallery visit

Start young

Children are naturally curious, so start young and make gallery visits a normal activity.

Expose babies to art as soon as possible: research proves regular engagement with art develops children’s aesthetic sensibilities and even very young children can respond to art in complex ways.

I remember my baby son neighing like a horse in front of a painting before he could talk. I looked at the painting he was staring at, Nicholas Harding’s Bob’s daily swim. There in the thick, painterly background, was a horse. My son connected with the work because he loved horses.

Before your visit

Look for ways to introduce your child to artists before your visit. Art activities bring exhibits to life in fun and engaging ways.

For example, from the NGA you can make Sol Le Witt-inspired vegemite toast. Suddenly, Wall drawing no.380 a-d (1982) takes on a whole new flavour, and your child is connected with the work before they see it.

Try to tap into your child’s interests. If they like superheroes, pop icons or Hollywood stars they might just love to see a show by Yankunytjatjara artist Kaylene Whiskey.

Marilyn JS Goodman’s brilliant book Children Draw includes tips on taking your child to a gallery: consider going on a weekday when it’s less crowded, include the cafe, and, importantly, don’t try to see everything – for younger children plan on spending no more than an hour and don’t try to look at too many art works.

Let your child take the lead and include them in the planning. Planning a trip together may be the perfect time to ask questions and share knowledge: “did you know we can’t touch artwork in galleries? Do you know why?”

This can not only help avoid awkward situations with security guards but also helps your child to understand why we don’t touch art (we need to protect the artworks), and may encourage further inquiry into the art or gallery.

There’s no right or wrong response

Some adults may feel uncomfortable talking about art. Just try having a conversation about what you see, and be prepared to be amazed by what your child observes.

Start by asking your child questions: what are you noticing about this exhibition? What stories are these works telling? What do you think about when you look at this artwork?

In schools, you might hear teachers use thinking routines: what do you see? What do you think about that? What does it make you wonder? This stimulates curiosity and encourages students to make careful observations and thoughtful interpretations.

Some galleries use Visual Thinking Strategies, which also consists of three questions: what’s going on in this picture? What makes you say that? What else can we find?

You don’t have to like what you see. This can even be a great stimulus for discussions with your child: does art have to be beautiful to be good? Why do people make art? What was that exhibition about?

Interact with the art

You are allowed to take pencil and paper into most galleries and drawing is a great way of looking and slowing down your experience.

Most galleries have seating where you can sit and draw. Try taking a sketchbook for you and one for your child. Role model drawing, taking your time. You are not aiming to make a masterpiece but to use drawing to map out what you see.

Compare drawings and swap notes. Ask your child what they noticed and share what you found.

Another fun game in a gallery is to pose like the sculptures and paintings.

Most galleries offer programs for children and families. By attending tours you can pick up excellent tips from the educators who are experts at engaging children. They use simple and effective methods such as rolling a piece of paper up into a telescope to look at a work.

Some galleries also have children’s trails especially designed for engaging children. And if they don’t, you can make things up like how many trees can you see? Or can you find any animals in this exhibition?

After the visit

In a previous article I talked about extending your child’s experience after a gallery visit and how a comic my son made gave me an insight into his feeling about what he had seen at the gallery.

Make it a special day out together. At the end of the day you want your child to enjoy the experience and foster a love of art.

Summer means salads. And salads are even more delicious with a good dressing.

Most salad dressings are temporarily stable mixtures of oil and water known as emulsions.

But how do salad dressing emulsions form? And how can we enhance our emulsions for better salads and more?

Read more:
How to make the perfect pavlova, according to chemistry experts

Oil and water don’t mix

It’s accepted wisdom that oil and water don’t mix. The water and oil molecules have distinct chemical properties that don’t interact well together.

You may have seen this if you’ve attempted to make a salad dressing by shaking together oil and vinegar (which is mostly water), which gives a temporary suspension that quickly separates.

There is a large energy cost to breaking apart and mixing the water and oil layers. The secret to blending them together is to add an extra ingredient known as a “surfactant” or emulsifier.

The name surfactant is derived from “surface active”. It highlights that these molecules work at the surface or interface to bridge the interactions between the oil and water. This is similar to how detergents are able to remove grease from your dishes.

Many vinaigrette recipes call for emulsifiers without specifically mentioning their crucial emulsifying role.

Key examples are mustard and garlic, which contain “mucilage” – a mix of carbohydrates – that can act as emulsifiers.

So if your vinegar/oil salad dressings are separating, make sure you’re adding enough of these ingredients (which also contain wonderful flavour chemicals).

Commercial salad dressings also contain naturally sourced emulsifying carbohydrates. These will often be listed on the ingredients as generic “vegetable gum” or similar, and you may need to read the label and delve a little deeper into the food additive number to find out the source.

Researchers have raised questions about synthetic emulsifiers used in processed food, as studies in mice suggest they have health risks. It’s too early to say exactly what this means for humans.

Shake it ‘til you make it

Mixing is key to dispersing oil in water. While shaking a jar is convenient, a whisk or food processor will give a more complete emulsion. The white (or opaque) colour of many emulsions is due to the formation of microdroplets that scatter light.

These mechanical mixing methods are even more essential for the formation of so-called “permanent emulsions” such as mayonnaise.

Mayonnaise is an emulsion of oil in water, but egg yolk is the key emulsifier. Egg yolks contain long molecules called phospholipids that are able to interact with both the oil layer and the water. Mayonnaise is an impressively stable emulsion, which is why is can be sold in a shelf-stable form.

But it isn’t infinitely stable; heating the mayonnaise emulsion will cause it to split. Perhaps you’ve hurriedly prepared a potato salad and added a mayonnaise-based dressing before the potatoes have cooled down?

Or toasted a sandwich spread with mayonnaise? (Incidentally, adding mayonnaise to the outside of a toasted sandwich is an excellent path to some delicious and crispy chemical reactions.)

The heat destabilises the emulsion and the separate oil and water phases will reform. Depending on the mixture, split emulsions may be recovered by adding more emulsifier and re-whisking or re-mixing.

Hollandaise sauce is a notoriously difficult emulsion to prepare. The traditional hollandaise method involves whisking egg yolk, water, and lemon juice over a low heat, then slowly adding melted butter with further whisking. Not only can the emulsion split, but you can also overcook the added emulsifying egg yolk.

The key to a successful hollandaise emulsion is separating the butter into fine, dispersed droplets, giving a thick and opaque mixture, but without cooking the eggs. Adding the butter too quickly or without sufficient mixing can give a split sauce.

Using an immersion blender can help, as can controlling the temperature of the melted butter. You might get a more consistently emulsified sauce with far less strain on your wrists.

You’ve got me feeling emulsions

Emulsions are used in many more places than salads and sauces. Most medicated creams, cosmetics and lotions are emulsions of oils and water, which is why they look white.

Gardeners might be familiar with a mixture known as “white oil” – a mixture of vegetable oil and detergent. This brew, when diluted in water, is an inexpensive, effective, yet mild insecticide. Commercial versions often contain other pesticides, so make sure you read the label.

Modern acrylic paints use emulsions for both their manufacturing and application. The emulsions suspend the paint polymers in a water base.

The water from the paint evaporates, leaving a film of paint polymers that can’t be re-dispersed into water. This clever chemical trick has saved huge quantities of oil-derived solvents from being used, inhaled, and emitted into the environment from traditional oil-based paints.

Modern vaccines use emulsions to increase the immune systems response. Other common emulsions are inks, ice cream, margarine and hair products, to name just a few.

So next time you’re making a salad, check your emulsions. Opposites don’t attract, but mixing them with the right chemistry can give a delicious result.

As you’re driving around this summer holidays, there’s every chance you’ll see a strange-looking white or yellow box on the side of the road.

It might have cameras protruding overhead, or be emblazoned with road safety slogans.

It’s a mobile road safety camera. It’ll catch you out doing everything from speeding, to using your phone while driving, to failing to wear a seat belt.

So how did these cameras come about, and how do they work?

How to never get a speeding fine again — and maybe save a child’s life

Road toll refusing to budge

In Australia, around 1,200 people die in car crashes every year.

The number of people seriously injured has risen from 34,000 in 2011 to around 39,000 in 2019 (although this may partly be explained by changes in the way admissions to hospital are reported).

Alarmingly, these numbers are showing no sign of decline.

It is widely recognised that behaviours such as speeding, drink or drug driving, fatigue, distraction and dangerous driving increase the risk of a crash.

Failing to wear a seat belt can lead to more severe injuries when a crash occurs.

To reduce the trauma on our roads caused by these behaviours, we need to increase compliance with the road rules and encourage safer driving. The use of safety cameras for enforcement has become a crucial part of the road safety response.

A short history of safety cameras

Safety cameras were first used in Australia in 1985 with the introduction of speed cameras in Victoria.

Since then, the use of safety cameras has grown to include fixed red light and speed cameras, mobile speed cameras (that can be moved to different locations), and point-to-point cameras (also known as average speed cameras).

In the past three years, mobile phone detection cameras have been introduced in New South Wales, Queensland, Victoria, the ACT and Tasmania, and will soon be operating in South Australia. They have also been trialled in Western Australia.

Currently, Queensland and Tasmania are the only states to also use these cameras for seat belt enforcement, although NSW intends to do so in 2024.

Safety cameras, whether looking at speed or other dangerous driving behaviours, can be either fixed or mobile.

Fixed cameras are permanently located at one spot and operate around the clock. They have primarily been used to target speeding and red light running.

Mobile cameras, those roadside trailers you might see, can be moved from one location to another and can be deployed virtually anywhere at any time. They are mainly used to target speeding and can also be mounted on a vehicle or tripod.

Trailer-based safety cameras can be left unattended in place for longer periods and are usually equipped with security devices such as alarms and security cameras. They also have a secure housing (that’s sometimes bulletproof) to protect against tampering and vandalism.

Typically, they’re placed in areas with a history of crashes or where speeding, distraction, restraint use, or safety are of concern.

So how do they actually work?

Safety cameras use radar or laser to detect and measure vehicle speeds. Sensors embedded in the road are used to detect red light running.

Depending on how they are set up, safety cameras can monitor multiple vehicles across multiple lanes and approaching from opposite directions.

They use high-definition cameras that are effective in different lighting and weather conditions, including night, fog and heavy rain. Some are able to identify and enforce speed limits for different types of vehicles (like heavy vehicles).

They may also use automated number plate recognition capabilities that allow them to detect or identify so-called “hot list” vehicles that are of interest to police (stolen, unregistered, unlicensed owners, for example).

Fixed and mobile cameras enforce speeds in their immediate vicinity, while point-to-point cameras measure the average speed of vehicles between two points and as vehicles pass the camera locations at the beginning and end of the zone. Currently point-to-point enforcement is fixed, but it is likely that portable cameras will also be used in the future.

Mobile phone detection cameras make use of high-definition cameras and infrared lighting that allow them to see through the windscreen and determine when someone is illegally using a mobile phone. They can also determine whether they are wearing their seat belt correctly.

These cameras can also measure vehicle speed and use number plate recognition to monitor vehicles. It means they can help enforce pretty much everything. They can be either fixed or mobile.

Do they work to improve driver behaviour?

Research indicates safety cameras do just what the label implies: improve safety.

A systematic review of the effects of different types of speed cameras suggests they are effective at reducing average speeds and the number of vehicles speeding, and, more importantly, reduce serious injury and fatal crashes by around 20% each.

Studies examining the effectiveness of mobile phone cameras are yet to be undertaken. However, NSW experienced a substantial decline in mobile phone use in the three years following their introduction.

Read more:
Speeding is more common among people regularly exposed to content encouraging speeding

Enforcement data also shows that the cameras are an efficient and effective method ofdetecting infringements.

Merely relying on common sense, courtesy or self-interest will not be enough to reduce the trauma caused by bad driver behaviour.

Safety cameras work. They will continue to play an important part in reducing these behaviours and making our roads safer for everyone.

End-of-year results aren’t only for school and university students. Countries, too, can be measured for their progress – or lack of it – across numerous categories and subject areas.

This report card provides a snapshot of how New Zealand has fared in 2023. Given the change of government, it will be a useful benchmark for future progress reports. (Somewhat appropriately, the coalition seems keen on standardised testing in education.)

It’s important to remember that this exercise is for fun and debate. International and domestic indices and rankings should be read with a degree of caution – measurements, metrics and numbers from 2023 tell us only so much.

Nevertheless, it’s still possible to trace the nation’s ups and downs. As the year draws to an end, we can use these statistics and rankings to decide whether New Zealand really is the best country in the world – or whether we need to make some additional new year’s resolutions.

International pass marks

Overall, the country held its own internationally when it came to democratic values, freedoms and standards. But there was a little slippage.

Despite falling a spot, Transparency International ranked New Zealand second-equal (next to Finland) for being relatively corruption-free.

In the Global Peace Index, New Zealand dropped two places, now fourth-best for safety and security, low domestic and international conflict, and degree of militarisation.

The country held its ground in two categories. Freedom House underlined New Zealand’s near-perfect score of 99 out of 100 for political and civil liberties – but three Scandinavian countries scored a perfect 100. The Global Gender Gap Report recorded New Zealand as steady, the fourth-most-gender-equal country.

Supplementary work by the United Nations Development Programme shows New Zealand making impressive strides in breaking down gender bias.

The Index for Economic Freedom, which covers everything from property rights to financial freedom, again placed New Zealand fifth, but our grade average is falling. We also dropped a place in the World Justice Project’s Rule of Law Index to eighth.

New Zealanders are about as happy as they were last year, still the tenth-most-cheery nation, according to the World Happiness Report.

The Human Development Index did not report this year (New Zealand was 13th in 2022). But the Legatum Prosperity Index, another broad measure covering everything from social capital to living conditions, put New Zealand tenth overall – reflecting a slow decline from seventh in 2011.

The Economist’s Global Liveability Index has Auckland at equal tenth, with Wellington racing up the charts to 23rd. (Hamilton, my home, is yet to register.)

While New Zealand registered a gradual slide in the Reporters Without Borders Press Freedom Index, at 13th position it still ranks highly by comparison with other nations.

Could do better

New Zealand has seen some progress around assessment of terror risk. While the national terror threat level has remained at “low”, the Global Terrorism Index ranked the country 46th – lower than the US, UK and Russia, but higher than Australia at 69th.

The country’s previous drop to 31st in the Global Competitiveness Report has stabilised, staying the same in 2023.

On the Global Innovation Index, we came in 27th out of 132 economies – three spots worse than last year. The Globalisation Index, which looks at economic, social and political contexts, ranks New Zealand only 42nd.

But the country’s response to climate change is still considered “highly insufficient” by the Climate Action Tracker, which measures progress on meeting agreed global warming targets. The Climate Change Performance Index is a little more generous, pegging New Zealand at 34th, still down one spot on last year.

New Zealand’s overseas development assistance – low as a percentage of GDP compared to other OECD countries – had mixed reviews.

The Principled Aid Index – which looks at the purposes of aid for global co-operation, public spiritedness and addressing critical development goals – ranks New Zealand a lowly 22 out of 29.

The Commitment to Development Index, which measures aid as well as other policies (from health to trade) of 40 of the world’s most powerful countries, has New Zealand in 19th place.

Decent economic grades

The economic numbers at home still tell a generally encouraging story:

• unemployment remains low at 3.9%, still below the OECD average of 4.8%.

• median weekly earnings from wages and salaries continued to rise, by NZ$84 (7.1%) to $1,273 in the year to June

• inflation is rising, but the rate is slowing, falling to 5.6% in the 12 months to September

• and good or bad news according to one’s perspective, annual house price growth appears to be slowly recovering, with the average price now $907,387 – still considerably down from the peak at the turn of 2022.

It’s worth noting, too, that record net migration gain is boosting economic measurements. In the year to October 2023, 245,600 people arrived, with 116,700 departing, for an annual net gain of 128,900 people.

Room for social improvement

In the year to June, recorded suicides increased to 565, or 10.6 people per 100,000. While an increase from 10.2 in 2022, this is still lower than the average rate over the past 14 years.

Incarceration rates began to rise again, climbing to 8,893 by the end of September, moving back towards the 10,000 figure from 2020.

Child poverty appears to be stabilising, with some reports suggesting improvements in longer-term trends. While commendable, this needs to be seen in perspective: one in ten children still live in households experiencing material hardship.

The stock of public housing continues to increase. As of October, there were 80,211 public houses, an increase of 3,940 from June 2022.

In short, New Zealand retains some bragging rights in important areas and is making modest progress in others, but that’s far from the whole picture. The final verdict has to be: a satisfactory to good effort, but considerable room for improvement.

At this time of year many of us resolve to prioritise our health. So it is no surprise there’s a roaring trade of products purporting to guarantee you live longer, be healthier and look more youthful.

While an estimated 25% of longevity is determined by our genes, the rest is determined by what we do, day to day.

There are no quick fixes or short cuts to living longer and healthier lives, but the science is clear on the key principles. Here are five things you can do to extend your lifespan and improve your health.

Read more:
No, you can’t reverse ageing by injecting ‘young blood’ and fasting. But that doesn’t stop people trying

1. Eat a predominantly plant-based diet

What you eat has a huge impact on your health. The evidence overwhelmingly shows eating a diet high in plant-based foods is associated with health and longevity.

If you eat more plant-based foods and less meat, processed foods, sugar and salt, you reduce your risk of a range of illnesses that shorten our lives, including heart disease and cancer.

Plant-based foods are rich in nutrients, phytochemicals, antioxidants and fibre. They’re also anti-inflammatory. All of this protects against damage to our cells as we age, which helps prevent disease.

No particular diet is right for everyone but one of the most studied and healthiest is the Mediterranean diet. It’s based on the eating patterns of people who live in countries around the Mediterranean Sea and emphases vegetables, fruits, wholegrains, legumes, nuts and seeds, fish and seafood, and olive oil.

2. Aim for a healthy weight

Another important way you can be healthier is to try and achieve a healthy weight, as obesity increases the risk of a number of health problems that shorten our lives.

Obesity puts strain on all of our body systems and has a whole myriad of physiological effects including causing inflammation and hormonal disturbances. These increase your chances of a number of diseases, including heart disease, stroke, high blood pressure, diabetes and a number of cancers.

Read more:
The body mass index can’t tell us if we’re healthy. Here’s what we should use instead

In addition to affecting us physically, obesity is also associated with poorer psychological health. It’s linked to depression, low self-esteem and stress.

One of the biggest challenges we face in the developed world is that we live in an environment that promotes obesity. The ubiquitous marketing and the easy availability of high-calorie foods our bodies are hard-wired to crave mean it’s easy to consume too many calories.

3. Exercise regularly

We all know that exercise is good for us – the most common resolution we make this time of year is to do more exercise and to get fitter. Regular exercise protects against chronic illness, lowers your stress and improves your mental health.

While one of the ways exercising helps you is by supporting you to control your weight and lowering your body fat levels, the effects are broader and include improving your glucose (blood sugar) use, lowering your blood pressure, reducing inflammation and improving blood flow and heart function.

While it’s easy to get caught up in all of the hype about different exercise strategies, the evidence suggests that any way you can include physical activity in your day has health benefits. You don’t have to run marathons or go to the gym for hours every day. Build movement into your day in any way that you can and do things that you enjoy.

Can’t afford a gym membership or fitness class? 3 things to include in a DIY exercise program

4. Don’t smoke

If you want to be healthier and live longer then don’t smoke or vape.

Smoking cigarettes affects almost every organ in the body and is associated with both a shorter and lower quality of life. There is no safe level of smoking – every cigarette increases your chances of developing a range of cancers, heart disease and diabetes.

Even if you have been smoking for years, by giving up smoking at any age you can experience health benefits almost immediately, and you can reverse many of the harmful effects of smoking.

If you’re thinking of switching to vapes as a healthy long term option, think again. The long term health effects of vaping are not fully understood and they come with their own health risks.

5. Prioritise social connection

When we talk about living healthier and longer, we tend to focus on what we do to our physical bodies. But one of the most important discoveries over the past decade has been the recognition of the importance of spiritual and psychological health.

People who are lonely and socially isolated have a much higher risk of dying early and are more likely to suffer from heart disease, stroke, dementia as well as anxiety and depression.

Read more:
Are you part of a social group? Making sure you are will improve your health

Although we don’t fully understand the mechanisms, it’s likely due to both behavioural and biological factors. While people who are more socially connected are more likely to engage in healthy behaviours, there also seems to be a more direct physiological effect of loneliness on the body.

So if you want to be healthier and live longer, build and maintain your connections to others.

As each day passes, the need to protect Australia’s environment grows more urgent. As noted in the most recent State of Environment Report in 2021, we are increasingly turning to “measures of last resort” to prevent species extinctions and the collapse of ecosystems.

In legal theory, the “rights of nature” acknowledges all Earth’s natural elements as having an inherent right to exist and flourish.

Developments towards recognition of the rights of nature have attracted international attention. In some countries, they have come about through legislative reform, constitutional amendment and the courts.

In Australia, federal, state and territory parliaments have not shown much appetite for introducing the rights of nature principle into legislation. The Murray-Darling River System (Rights of Nature) Bill 2021 in New South Wales and the Rights of Nature and Future Generations Bill 2019 in Western Australia raised the possibility, but did not progress. One exception is Victoria, where a law protecting the Yarra river and its First Nations custodianship was passed in 2017.

Around the globe, lawyers and policy makers have been engaged in finding ways the law can contribute to the protection of ecosystems. Conferring ecosystems with rights is one strategy we can use to prevent species extinctions and ensure a “voice” for nature.

Three rivers are now legally people – but that’s just the start of looking after them

Rivers as legal persons

Central to these efforts has been realising the rights of nature based on legal personhood, which confers entitlements and duties on an entity. There are benefits, complexities and risks involved in this approach.

Indeed, the use of legal personhood as a mechanism to give natural entities like rivers or wetlands rights has been criticised from a First Nations perspective.

At a time when we are seeing threats to the environment turn into catastrophes with alarming frequency, the law can be an inflexible tool and slow to respond.

In Australia, the rights of nature idea is emerging in social and political debate. Ultimately, the success of the rights of nature vision depends on effective broad legal frameworks combined with local action.

Sometimes, we can overlook the significant role local-level reform can play. So it is encouraging to see communities and councils leading the way.

The rights of nature principle provides a framework a local community can use when wanting to show its respect for nature and ensure due care for the local ecosystem.

Two examples of local governance

Two examples of such local leadership are the Blue Mountains City Council in NSW and the Shire of Augusta Margaret River local government area in WA.

In 2021, the Blue Mountains City Council received a Center for Democratic and Environmental Rights Local Recognition Award for its commitment to embedding rights of nature principles into its operations. The rights of nature principle is reflected in the Blue Mountains Community Strategic Plan 2035: “natural environment is valued for its intrinsic nature and role in maintaining all forms of life”.

In rights talk, “intrinsic value” means that a thing or being has value “in itself”, or “for its own sake”.

For example, a tree has intrinsic value for its own sake because it is a living thing and the tree’s life has value in and of itself. The tree’s value is not based on how it can be used by humans.

With some exceptions, Western philosophers have confined intrinsic value to human beings alone. The same notion permeates the law. Yet recognising the intrinsic value of other species and our broader environment is a pathway to ethical reflection and has the potential to transform our perspective.

In Western Australia, following community advocacy, the Shire of Augusta Margaret River has also shown leadership in this regard. Among other things, the shire’s May 2023 Overarching Sustainability Policy requires due regard for “the needs, rights and wisdom of Traditional Custodians” and “the rights of nature to exist, thrive and evolve”.

How Traditional Owners and officials came together to protect a stunning stretch of WA coast

Caring for Country

We believe these local examples give cause for optimism and a source of “slow hope”. And First Nations leadership sits at the heart of these developments. Community-led approaches are key to caring for Country, something that’s also noted in the latest State of the Environment report.

Best-practice local policy development can actively enable caring for Country and integrate it into the regulatory conversations that inform the operational plans of councils.

For the CSIRO First Nations Australian Peoples led research initiative Our Knowledge, Our Way, connection to Country is a cultural must. For First Nations peoples, Country already has “rights”: to be cared for, respected and listened to. This is a relationship that arises organically and is entwined in the experience of being human.

From a Western perspective, enshrining rights of nature thinking in environmental stewardship at all levels of society is something environmental ethicists describe as essential.

Local communities can draw upon these two convergent lines of thinking to inform culturally sensitive collaboration. While higher levels of government are yet to introduce the principle of rights of nature into legislation, leadership at local levels is showing us it can be done. State and federal governments should take note.

Retail activity has been a defining facet of cities since antiquity. The Greek Agora and Roman Forum may be viewed as the original CBDs – central business districts, or what urban planners call activity centres.

Retail spaces have evolved over time. Urbanisation, mass production and the rise of conspicuous consumption led to the high street and CBD dominating the retail landscape across the Western world from the late 19th century until the mid-20th century.

The 21st-century retail landscape has become more diverse and competitive. The range of physical and virtual retail spaces, retailers, products and prices leaves consumers spoilt for choice.

Retailing is more than just about consumption. It’s Australia’s fourth-largest employment sector and plays a major role in shaping our cities. Retail helps define a city’s identity and brand and thus attract visitors. But the retail landscape and consumer behaviour are changing, and changing fast!

What makes an ideal main street? This is what shoppers told us

The place to be and be seen

In Australia (and elsewhere), the CBD was at the epicentre of the evolution of discrete retail spaces. It offered a smorgasbord of independently owned shops, national and international chain stores and department stores. These were located in laneways, shopping arcades, main streets and multistorey shopping centres.

Centrality, easy public transport access and a largely suburban-based commuter workforce explain the dominance of the CBD in the 20th century.

A visit to the CBD on a Saturday was more than just a utilitarian shopping trip. It could be an urban exploration, a leisure pursuit, a pleasure-seeking adventure, a social event.

Children accompanying their parents were mesmerised by the intensity of urbanism and retail choice. Teenagers and young people, much like 19th-century flaneurs, paraded with their peers, their fashion denoting their subcultural affiliation.

For adults, the CBD offered a chance to indulge in retail therapy via window shopping and pleasurable consumption. For others a trip to the CBD allowed them to treat themselves and meet friends at the department store cafe.

In short, the CBD was the place to see and be seen.

CBD’s retail crown slips

The dominance of the CBD began to slip with the emergence of suburban shopping centres in the late 1950s – thank you, Victor Gruen. Rapid suburban growth, social mobility and increased car use drove an explosion in suburban shopping centres from the 1960s through to the 1980s.

According to the Shopping Centre Council of Australia, an average of 22 shopping centres a year have been built since the first centre, Brisbane’s Chermside, appeared in 1957.

Competition between CBD retailers and shopping centres intensified in the 1980s and 1990s. With the rise of online retailing in the past decade or so, these bricks-and-mortar retailers have had to lift their game again.

Retailing matters. Aussie consumers spent a whopping A$353 billion on retail goods in 2022 compared with $275.3 billion in 2018 – a 28.2% increase.

Over the same period, online retail spending increased by 132% from $27.5 billion to $63.8 billion. It now accounts for just over 18% of retail spending in Australia, up from 10% in 2018.

The “4 Cs” underpin the rise of online shopping: convenience, choice, competitive prices and COVID-19 (which ramped up the shift).

Big, bigger, biggest: Black Friday, Cyber Monday and Singles Day

COVID and working from home led to Australian CBDs, especially Melbourne and Sydney, losing considerable ground, while suburban shopping centres gained in terms of shopper numbers and spending.

Although zombified CBDs at the height of pandemic restrictions are in the rear-view mirror, working from home lingers. This is especially true for Melbourne where office occupancy averages 53% – way behind Perth (91%), Adelaide (85%), Sydney and Brisbane (both 75%).

Capital city councils, state governments and bodies such as the Committee for Sydney, Urban Development Institute of Australia and the Property Council of Australia have taken or advocated action to draw people back to the CBD.

Actions include everything from free parking and public transport, tactical urbanism or temporary changes to the streetscape such as pedestrian plazas, pop-up bike lanes, and parklets, outdoor dining, public events and vouchers, through to changes in planning regulations to speed up high-density residential development.

How COVID all but killed the Australian CBD

Cathedrals of consumption … and then some

Before and since COVID-19 major shopping centres across Australia have undergone multi-million-dollar refurbishments and redesign. They include centres in Adelaide (Marion), Brisbane (Chermside, Pacific Fair), Melbourne (Chadstone, Fountain Gate), Perth (Carousel, Karrinyup) and Sydney (Parramatta, Macquarie Centre). The centres have increased floorspace and diversified retail, entertainment and food and beverage offerings.

Suburban shopping centres are more than cathedrals of consumption. Mega-malls such as Chadstone (215,000m²), Fountain Gate (178,000m²) and Chermside (177,000m²) stand out as major hubs of economic activity and employment, tourist attractions and social and community spaces.

To help secure a ready customer base, upmarket hotels and luxury residential developments have been built, or are earmarked for development, as part of major shopping centres. Many more such residential developments in Australia (and the US) are likely over the next decade or so.

The suburbs are the future of post-COVID retail

Devil in the retail

The competition between bricks-and-mortar retailers in CBDs, suburban shopping centres and online retailers peaks each year with the onset of Black Friday and Cyber Monday in late November, closely followed by the Christmas shopping season and New Year sales.

Whatever big changes come next – in terms of what we buy, where and how – will have implications well beyond the retail sector. The structure and function of cities, plus our relationship with the city and retail spaces, are likely to change.

With the rise of online shopping and on-demand delivery, can we, for example, expect to see our streets and skies soon filled with autonomous robots and drones?

Autonomous delivery raises major questions about retail, urban and residential design, infrastructure provision, employment, human behaviour and, ultimately, regulation. Therein lies the devil in the retail.

As the old year passes and a new one arrives, three notable sport events occupy the languid vacation hours. Melbourne’s Boxing Day and Sydney’s New Year’s Test matches are spliced by the Sydney to Hobart Yacht Race.

Unlike the race, a set-piece seasonal spectacle notable mainly for its Rolex-sponsored affluence, picturesque helicopter shots, and (seemingly) AI-generated reporting, the cricket stirs strong emotions.

Many people are seduced by the nostalgic notion that no Australian summer is complete without two metropolitan Test matches played on green fields. Much of the experience involves half-watched television and part-heard radio broadcasts.

But anyone who messes with these national treasures risks accusations of the greatest national sin – being un-Australian.

Adored matches with short histories

Like many “traditions”, the Boxing Day Test at the Melbourne Cricket Ground (MCG) is quite recent – in fact, barely 40 years old.

It is the product of jet travel, global year-round tour schedules and, especially, the needs of commercial television.

Kerry Packer grasped the lucrative potential of large, captive audiences on vacation. Acquiring the broadcast rights in 1979, he set about maximising their value for Channel Nine. Before then, Boxing Day Tests in Melbourne were intermittent, with three in the 1970s even being staged in Adelaide.

Fairly regular Tests at the Sydney Cricket Ground (SCG) in January and February began in the late 1960s, but it was not until the late 1990s that they settled on the first week of the year. Patriotic television advertisements substantially created this misleading picture of time-honoured festive cricket rituals.

An evolving game with a crowded calendar

In the midst of this orgy of cricketing nostalgia and overindulgence of food and liquid, purists find the mounting threats to the five-day format unpalatable.

It is hard to imagine today that one-day cricket was once regarded as the “fast food” version of the game.

But that was before we got the memo from, in particular, the men’s and women’s Indian Premier League.

Here, players are literally bought and sold in a sporting meat market, along with megabuck franchises. Cricket contests are shrunk to 20-over “big bashes” of barely three hours’ duration, the senses bombarded with music, dance, programmed crowd stimulation and loud advertisements.

This Twenty20 form of the game has mushroomed around the world, including in the sportswashing capitals of the Middle East. It has been joined recently by a newer, fast-paced variation called The Hundred to compete with the slower, longer one-day and Test forms of the game.

After more than a century in the Olympic wilderness, cricket is also returning to the fold at the 2028 Los Angeles Games, courtesy of some heavy lobbying by India. It may well feature at the 2032 Brisbane Games, where its famous venue, the Gabba, will be rebuilt.

Consequently, the global cricket calendar is becoming even more congested. A clear case is the Twenty20 series that took place in India within four days of the month-long men’s 2023 World Cup.

The teams that played in the one-day final, Australia and India, faced off again in the Twenty20. But half the Australian team returned home, and only one of the Indian one-day team participated.

Such time pressures and competition variations encourage more players and coaches to specialise in different cricket formats. The money is comparatively easy in the short form of the game, while the physical and mental health toll can be reduced by opting out of Test and even one-day cricket altogether.

Suffering in the name of tradition

The Australian cricketers who do play in future Melbourne and Sydney Tests may find they will move west to Adelaide or Perth, or north to Brisbane. As Cricket Australia goes to tender for its new seven-year broadcast contract, it has made clear that no venue has a guaranteed Test match.

Of course, such matters are being raised in a play for more cash. But with expensive new stadia to fill and state governments offering juicy inducements to snag a prestigious Test match, Australia’s two largest cities may be dismissed on these crucial days.

There is also the problem of the frequently sodden Sydney, with agitation that the key New Year’s Test should be moved from one of the wettest cities where elite cricket is played.

To preserve the heritage value of the New Year’s Test, must bored, damp spectators sit in the stands? Or TV viewers be forced to watch images of a covered pitch and listen to droning fill-in commentary?

As the COVID pandemic lockdown showed, sports like cricket now resemble continuous-process manufacturing industries, or global just-in-time operations where the “product” is assembled via intricate logistics.

The lines between tradition and progress constantly shift in these hyper-commercial cricketing times. One casualty may be the largely illusionary sense of continuity proffered by Australia’s Boxing Day and New Year double bill.

As we enter the festive season it’s a good time to think about what all those celebratory alcoholic drinks can do to your gut.

Alcohol can interfere with the time it takes for food to go through your gut (also known as the “transit time”). In particular, it can affect the muscles of the stomach and the small bowel (also known as the small intestine).

So, how and why does alcohol make your poos goes weird? Here’s what you need to know.

À lire aussi :
Got gastro? Here’s why eating bananas helps but drinking flat lemonade might not

Diarrhoea and the ‘transit time’

Alcohol’s effect on stomach transit time depends on the alcohol concentration.

In general, alcoholic beverages such as whisky and vodka with high alcohol concentrations (above 15%) slow down the movement of food in the stomach.

Beverages with comparatively low alcohol concentrations (such as wine and beer) speed up the movement of food in the stomach.

These changes in gut transit explain why some people can get a sensation of fullness and abdominal discomfort when they drink vodka or whisky.

How long someone has been drinking a lot of alcohol can affect small bowel transit.

We know from experiments with rats that chronic use of alcohol accelerates the transit of food through the stomach and small bowel.

This shortened transit time through the small bowel also happens when humans drink a lot of alcohol, and is linked to diarrhoea.

Alcohol can also reduce the absorption of carbohydrates, proteins and fats in the duodenum (the first part of the small bowel).

Alcohol can lead to reduced absorption of xylose (a type of sugar). This means diarrhoea is more likely to occur in drinkers who also consume a lot of sugary foods such as sweets and sweetened juices.

Chronic alcohol use is also linked to:

• lactose intolerance

• overgrowth of small bowel bacteria and

• reduced absorption of fats from the pancreas not producing enough digestive enzymes.

This means chronic alcohol use may lead to diarrhoea and loose stools.

How might a night of heavy drinking affect your poos?

When rats are exposed to high doses of alcohol over a short period of time, it results in small bowel transit delay.

This suggests acute alcohol intake (such as an episode of binge drinking) is more likely to lead to constipation than diarrhoea.

This is backed up by recent research studying the effects of alcohol in 507 university students.

These students had their stools collected and analysed, and were asked to fill out a stool form questionnaire known as the Bristol Stool Chart.

The research found a heavy drinking episode was associated with harder, firm bowel motions.

In particular, those who consumed more alcohol had more Type 1 stools, which are separate hard lumps that look or feel a bit like nuts.

The researchers believed this acute alcohol intake results in small bowel transit delay; the food stayed for longer in the intestines, meaning more water was absorbed from the stool back into the body. This led to drier, harder stools.

Interestingly, the researchers also found there was more of a type of bacteria known as “Actinobacteria” in heavy drinkers than in non-drinkers.

This suggests bacteria may have a role to play in stool consistency.

But binge drinking doesn’t always lead to constipation. Binge drinking in patients with irritable bowel syndrom (IBS), for example, clearly leads to diarrhoea, nausea and abdominal pain.

What can I do about all this?

If you’re suffering from unwanted bowel motion changes after drinking, the most effective way to address this is to limit your alcohol intake.

Some alcoholic beverages may affect your bowel motions more than others. If you notice a pattern of troubling poos after drinking certain drinks, it may be sensible to cut back on those beverages.

If you tend to get diarrhoea after drinking, avoid mixing alcohol with caffeinated drinks. Caffeine is known to stimulate contractions of the colon and so could worsen diarrhoea.

If constipation after drinking is the problem, then staying hydrated is important. Drinking plenty of water before drinking alcohol (and having water in between drinks and after the party is over) can help reduce dehydration and constipation.

You should also eat before drinking alcohol, particularly protein and fibre-rich foods.

Food in the stomach can slow the absorption of alcohol and may help protect against the negative effects of alcohol on the gut lining.

Is it anything to worry about?

Changes in bowel motions after drinking are usually short term and, for the most part, resolve themselves pretty efficiently.

But if symptoms such as diarrhoea persist beyond a couple of days after stopping alcohol, it may signify other concerning issues such as an underlying gut disorder like inflammatory bowel disease.

Researchers have also linked alcohol consumption to the development of irritable bowel syndrome.

If problems persist or if there are alarming symptoms such as blood in your stool, seek medical advice from a general practitioner.

In the hit dystopian TV series Severance, employees at biotech corporation Lumon Industries find it easy to separate work and home life. A computer chip is inserted in their brains to act as a “mindwipe”. They leave all thoughts of home behind while at work, and completely forget about their work when at home.

While the show explores the pitfalls of such a split in consciousness, there’s no denying it’s a tantalising prospect to be able to “flick the off switch” and forget about work whenever you’re not actually supposed to be working.

This is known as “psychological detachment”. People who can do it are happier and healthier, and experience less fatigue. But many of us struggle to detach and disconnect mentally from work, particularly when our jobs are demanding and stressful.

It may not be enough simply to be physically away from work, particularly in an era when so many of us work from home. We also have to stop thinking about work when we’re not there – whether it’s fretting over your to-do list while out at dinner, thinking about your unanswered emails while you’re at your daughter’s soccer game, or lying in bed pondering what you’ll say at tomorrow’s board meeting.

The art of detachment

Your choice of activity outside work can be crucial to this process of psychological detachment. To learn more about what strategies are most effective, my research surveyed nurses who were working shifts in hospital emergency departments in 2020, a highly stressful work environment.

My colleagues and I collected data from 166 nurses, using a survey called the Recovery Experience Questionnaire. This included collecting information about the underlying psychological experiences associated with home-time activities, such as feeling relaxed while reading a book or going for a walk.

Importantly, our survey results also showed nurses who were better able to forget about work had less fatigue and better physical and mental health.

Our results identified three key strategies that helped our survey participants to reduce fatigue and mentally recover from work:

• exercise
• spending time with family and friends
• leisure pursuits.

The physical benefits of exercise are well known. But exercising – whether it’s doing yoga, going for a run or playing netball – also brings mental benefits by encouraging you to focus deeply on what you’re doing rather than dwelling on outside thoughts.

Friendship and social connection are also good for our wellbeing. Research suggests people who have plenty of friends and confidants are less likely to die from chronic disease. And one study found people who undertake a difficult task with the help of a friend have fewer abrupt changes in heart rate than those who tackle the task alone.

Deliberately making time to spend with family, friends or pets can help us forget about work at home, and to centre our attention instead on what is important to us besides work.

Many of the nurses in our study reduced the effects of fatigue during home time by pursuing hobbies and interests such as sewing or gardening. But you shouldn’t worry too much about what specific activity you pursue – the main thing is to pick something you find pleasurable and engaging, and which fits comfortably around your existing commitments.

Leave your work at work

Finally, switching off from work also means not letting your work come home with you. Where possible, complete all your daily tasks so these aren’t on your mind at home. Unplug from work-related technology by not checking work emails or texts.

Of course, technology and working from home have now made separating work and home even harder. But setting healthy routines can help put mental as well as physical boundaries around your work time – even when your workplace is in the next room.

The idea that we can comfortably manage all the different facets of life – work, family, other responsibilities – is certainly appealing. But in reality, there is no one-size-fits-all solution to work-life balance – especially for older workers.

Making up a third of the New Zealand workforce, older workers (aged 55 and older) are a growing cohort in the economy.

There is the temptation to treat everyone in this age bracket as the same. But our new research shows this is a mistake. In fact, the support older workers want in order to achieve better work-life balance can differ as they age.

Indeed, the lives of older workers can vary greatly when it comes to employment, family structure, financial resources, time and wellbeing.

As the number of older employees in the economy grows, it’s important to understand what will help keep them satisfied in their work as they move towards and beyond retirement age.

Anxiety, depression and older workers

The goal of our research was to better understand the effects of work-life balance on anxiety and depression caused by job stress among older workers.

We asked two key questions: what effect does work-life balance have on older employees? And are there differences between groups of workers?

We surveyed 512 New Zealand employees in three age groups: 55-59 years, 60-64, and 65-plus. Respondents had been in their current jobs for an average of 12.6 years.

Some 58.2% were in the private sector, 31.6% were in the public/government sector, and 10.2% were in the not-for-profit sector.

In terms of age, 43.8% of respondents fell into the 55–59 age group. Those close to retirement age (60–64) made up 31.3% of respondents, and a further 25% were 65 and older – still working despite being eligible for superannuation.

Work-life balance at different ages

The average levels of work-life balance among the older workers we studied were high, comparing well with similar studies looking at other age groups. Those reporting high levels of work-life balance said they were able to comfortably manage their work, family and other responsibilities.

Job stress (when the demands of work exceed the resources of the employee), job anxiety (when the job is mentally stimulating but not enjoyable), and job depression (when there is little mental stimulation or enjoyment), can all affect wellbeing at work.

The 55–59 year-olds reported higher levels of job stress than older respondents. These younger older workers reported juggling stress that was fuelled by high job demands. Workers in this group were also managing the needs of younger families, often including children in their teenage years.

But respondents reported they experienced less stress in their jobs when their work-life balance was high. They subsequently had lower levels of anxiety and depression.

The younger cohort (55–59 years) reported the strongest benefits of having work-life balance. This effect reduced but remained significant as employees aged.

Five stereotypes about older workers debunked

Respondents who were 65 and older reported a reduction in job stress, and at levels significantly higher than the younger cohort with greater work-life balance.

Our analysis also showed the “retirement” group (those aged 65 and older) had the highest work-life balance, perhaps highlighting the strength of being “retired” (and receiving government income) while also being in paid employment.

At low levels of work-life balance, there was a significant difference in levels of job stress. Those in the younger age group (55–59 years) reported higher levels of job stress than respondents in the older age group.

When we compared this with respondents with high work-life balance, these differences were reversed, with respondents in the younger age group (55–59 years) reporting significantly lower job stress than the older age group.

Overall we found age – and proximity to the traditional retirement age – are important factors in how workers respond to work-life balance. Workers in the 55-59 age group still have a relatively long career ahead. For them, balancing work and life is especially beneficial.

Employers need to think differently

Managers need to understand that older workers are not a uniform group. It is important to develop age-relevant approaches to support the work-life balance of older employees.

Employers also need to consider how to allocate resources to support employee work-life balance across their lifespan.

These measures could include discussing interventions for managing job stress, as well as wellbeing resources that position ageing as positive. For example, using older managers as speakers in organisational wellness initiatives.

What is driving current labour market shortages and how older workers could help

By encouraging work-life balance, companies can foster lower levels of anxiety and depression and help staff find lasting job satisfaction.

Older people are often invisible in conversations about mental health. However, having older workers who are mentally strong, healthy and productive is increasingly essential for businesses.

Older workers themselves should also seek to understand what drives and diminishes their own work-life balance. It is an important predictor of wellbeing – especially as workers 55 and over could be an “older” worker for decades to come.

The Boxing Day sales are an essential part of Australia’s festive season.

Every year on December 26 news outlets invariably feature stories about excited shoppers queuing up at the major department stores hoping to score bargains and heavily discounted products. While such reports portray the day’s sales as a time-honoured tradition, they are only a recent ritual.

The origins of Boxing Day date back to the Middle Ages, when English masters gave their servants a day off after the Christmas celebrations. The servants would be given a box containing leftover food and treats to share with their families. In 1871 the day was formally recognised as a public holiday in the United Kingdom. Australian colonies later followed suit.

In the 19th and the early 20th centuries, the Boxing Day holiday was largely a day of rest and entertainment. Community sporting events were often held – a tradition that continues in Australia with the Boxing Day Test in Melbourne and the Sydney to Hobart yacht race.

As Boxing Day was an official public holiday, major retailers like department stores were not permitted to trade. These stores only re-opened for business three to five days after Christmas. Retailers certainly advertised “post Christmas bargains”, but most used this period to prepare for the annual stocktake sales that began shortly after New Year’s Day.

When the day became all about shopping

A gradual shift occurred during the economic boom after the second world war.

As consumer expenditure increased, the competition between retailers intensified. Eager to get ahead of the pack, Myer was advertising its “pre-stocktaking sale” in 1954. As others began their post-Christmas stocktake sales earlier, they became a key part of the retail annual cycle.

By the 1980s retail trading hours were coming under pressure. Since the beginning of the 20th century, retail was confined to 9am-6pm on weekdays and 9am-midday on Saturdays. Changing work patterns meant many Australians were only able to do their shopping in a mad rush on Saturday mornings. Over the 1980s and 1990s, trading hours were progressively extended in each state.

The liberalisation of Victoria’s retail trading hours coincided with a further intensification of competition across the department store sector. Daimaru, a Japanese department store, opened a branch in Melbourne in 1991. In its battle to steal market share from Myer and David Jones, Daimaru pioneered new initiatives, including 24-hour trading in the lead up to Christmas and trading on Boxing Day.

To promote its Boxing Day sale and generate a real buzz, Daimaru advertised a small number of enormously discounted products. These door buster sales worked. Crowds queued in the early hours of the morning to snare one of the bargains. As the doors opened, mayhem ensued as frenzied shoppers literally burst into the store.

The pursuit of a bargain got a little too serious

The appeal of the door buster sale took a hit in 1993 when one eager shopper lost the tips of her fingers in the store’s roller doors. Fearing further carnage, extreme discounts were subsequently dropped, but the crowds hoping to catch a bargain remained. By 2000, Boxing Day sales had become a firmly entrenched tradition.

Although the novelty had faded, Boxing Day sales nevertheless remained an exciting event. Television news crews continued to capture the excitement when the stores opened while newspapers reported on the size of crowds and what this revealed about the state of retail and the economy more generally.

By 2018, a discernible shift was occurring. Fewer people were queuing up and stores were opening later. The major department stores were no longer the dominant retailers they had once been. A broader range of brands and cheaper products could be found elsewhere, notably online, where bargains could be secured without the frustrations of dealing with other frantic shoppers.

The arrival of online shopping

Online shopping changed Australian shopping patterns as bargain hunters could now access overseas sales like Black Friday in the United States. Staged on the day after Thanksgiving, Black Friday is American retail’s busiest day that also kicks off the Christmas shopping season. Sales abound as retailers desperately chase shoppers.

Online has become an integral part of these sales, with Black Friday being extended to Cyber Monday. Australians shopping online have readily joined in.

An austere Christmas is on the cards – but don’t say recession

In 2022 Australians spent an estimated A$7.1 billion over the Black Friday sales period. While this figure is eclipsed by the $23.5 billion predicted for Boxing Day sales period, the reality is the gap is shrinking fast.

This year, it is predicted Australian expenditure on Black Friday will exceed that for Boxing Day.

Will Black Friday overtake Boxing Day?

So, are Boxing Day sales doomed to become another lost tradition? Large discounts and the convenience of shopping online have certainly helped Black Friday’s rapid growth. However, its real advantage is timing. Shoppers not only use these sales for themselves, they can do their Christmas shopping at the same time. Such a combination means Black Friday has quickly become a fixture in Australian retailing.

Of course, Boxing Day sales are not dead. Wherever there are bargains to be had, there will always be shoppers ready to buy. Rather than competing with Black Friday, it seems that the challenge for Australian retailers is to reinvent the Boxing Day sales tradition.

Maybe it’s time to bring back the door buster bargains.

A startling number of Australian rental homes come with an unwanted housemate: mould.

If you discover mould in a rented home, who is responsible and what can you do if the landlord seems unwilling to fix it?

Read more:
Climate-related disasters leave behind trauma and worse mental health. Housing uncertainty is a major reason why

Find the cause

The landlord is responsible if the mould is caused by the structural condition of the property. This can include things like leaking pipes, gutters, roofs or windows.

Tenants are responsible for mould remediation if the way they occupy a home has promoted mould growth. For example, if they have not been using exhaust fans in bathrooms, have been failing to ventilate their home or have been storing wet clothes in a cupboard.

This means establishing the cause of the mould is crucial to working out who’s responsible for repairs.

Why are so many rentals mouldy?

Australia has a rental home mould problem chiefly because much of our housing hasn’t been built to suit our climate. Houses tend not to be built with sufficient consideration of:

• efficient energy consumption to regulate indoor temperature

• the orientation of homes

• the use of double glazing and insulation to regulate temperature and humidity.

It is estimated that nearly 17% of privately rented homes and 22% of social housing dwelling require major repairs. This includes structural defects, such as large cracks in walls or leaking gutters, that can generate mould growth.

Tenant representatives have said in the past there is also a problem of weak enforcement of laws concerning the condition of rental homes.

4 ways to cut mould risk

To reduce your mould risk, you need to manage indoor moisture and temperature. Try to:

• keep the home well ventilated

• open windows and use exhaust fans in the bathroom and kitchen

• in humid climates, use air conditioning or a dehumidifier

• in cold climate, use a dehumidifier (desiccant dehumidifiers might more appropriate in very cold places)

• reduce moisture in the home by wiping up spills and condensation on surfaces

• dry washing outside

• if buying a dryer, opt for a condensing dryer instead of a conventional dryer (condensing driers put out much less vapour)

• report any structural issues (such as leaking pipes or windows that don’t close properly) to the agent or landlord as soon as you notice them.

Rental minimum standards differ by state or territory

In New South Wales, adequate ventilation is one of the minimum standards properties must meet to be considered fit to live in.

If the rental provider has been notified about mould problems in the house but has failed to act, you might consider getting advice from the Tenants’ Union of NSW.

Its fact sheet on mould also explains what to do if you’d like to contact the NSW Civil and Administrative Tribunal to apply for repairs, rent reduction or compensation.

In Victoria, rental minimum standards say “all rooms must be free from mould and damp caused by or related to the building structure.”

The Tenants Victoria website has information on how to ask a landlord to fix a mould problem or structural problems leading to mould and how to apply to the Victorian Civil and Administrative Tribunal if the landlord fails to act.

In Queensland, it depends on when you signed the lease. If you signed after September 1 this year (after new standards were introduced) tenants should notify the landlords of mould as soon as they discover it.

If mould is a result of problems with the property and the landlord doesn’t undertake repairs, tenants can contact the Queensland Civil and Administrative Tribunal.

The guidelines in Western Australia say the landlord must ensure the premises is “in a reasonable state of cleanliness and a reasonable state of repair […] and must conduct any repairs within a reasonable period after the need for the repair arises.” And in Western Australia, mould caused by faults in gutters or other fixtures is the responsibility of the rental provider. Further information on what to do if a dispute over the premises can’t be resolved amicably is available on the state government website.

In South Australia rental properties must be “reasonably free from mould or other irritants [and] reasonably free from the adverse effects of moisture or damp.” If a landlord refuses to fix something after being asked, the tenant can apply to the South Australian Civil and Administrative Tribunal.

In Tasmania, rental properties must be clean and in good repair when leased out. According to the Tasmanian government website on the issue,

‘Clean’ includes having no […] serious mould/rising damp issues.

If the tenant requests repairs and the landlord doesn’t act, the tenant can lodge a repair order with the Commisioner’s office.

In the Australian Capital Territory, the Tenants’ Union ACT has guidance on what to do if you discover mould in a property you rent.

In the Northern Territory, tenants may wish to seek advice from the Tenants’ Advice Service if there is a mould problem in a property they rent.

What policy change could help?

If the cause of indoor mould is related to the design and construction of the house, rental providers should act. But tenants may not have the information they need to determine and substantiate this claim and can’t do much to get rental providers to act on mould if it’s not clear what’s causing it. Also, renters often worry asking for repairs could lead to a rent increase or eviction.

Solutions include strengthening tenants rights to compel landlords to investigate the cause of mould in a house (given that knowing the cause is essential to assign responsibility for repairs). There should also be more stringent enforcement of current minimum standards relating to mould in rental properties.

Given the scale of problems like mould in Australian homes, policymakers may wish to consider whether a parliamentary inquiry on home environments and health is needed.

This would give Australians a chance to speak about their experiences – something that could help policy makers improve regulation in the rental sector.

Australians have used commercial creams, lotions or gels to manage our skin’s sun exposure for nearly a century.

But why we do it, the preparations themselves, and whether they work, has changed over time.

In this short history of sunscreen in Australia, we look at how we’ve slathered, slopped and spritzed our skin for sometimes surprising reasons.

Read more:
4½ myths about sunscreen and why they’re wrong

At first, suncreams helped you ‘tan with ease’

Sunscreens have been available in Australia since the 30s. Chemist Milton Blake made one of the first.

He used a kerosene heater to cook batches of “sunburn vanishing cream”, scented with French perfume.

His backyard business became H.A. Milton (Hamilton) Laboratories, which still makes sunscreens today.

Hamilton’s first cream claimed you could “
Sunbathe in Comfort and TAN with ease”. According to modern standards, it would have had an SPF (or sun protection factor) of 2.

Explainer: how does sunscreen work, what is SPF and can I still tan with it on?

The mirage of ‘safe tanning’

A tan was considered a “modern complexion” and for most of the 20th century, you might put something on your skin to help gain one. That’s when “safe tanning” (without burning) was thought possible.

Sunburn was known to be caused by the UVB component of ultraviolet (UV) light. UVA, however, was thought not to be involved in burning; it was just thought to darken the skin pigment melanin. So, medical authorities advised that by using a sunscreen that filtered out UVB, you could “safely tan” without burning.

But that was wrong.

From the 70s, medical research suggested UVA penetrated damagingly deep into the skin, causing ageing effects such as sunspots and wrinkles. And both UVA and UVB could cause skin cancer.

Sunscreens from the 80s sought to be “broad spectrum” – they filtered both UVB and UVA.

Researchers consequently recommended sunscreens for all skin tones, including for preventing sun damage in people with dark skin.

Sun damage and cancer: how UV radiation affects our skin

Delaying burning … or encouraging it?

Up to the 80s, sun preparations ranged from something that claimed to delay burning, to preparations that actively encouraged it to get that desirable tan – think, baby oil or coconut oil. Sun-worshippers even raided the kitchen cabinet, slicking olive oil on their skin.

One manufacturer’s “sun lotion” might effectively filter UVB; another’s merely basted you like a roast chicken.

Since labelling laws before the 80s didn’t require manufacturers to list the ingredients, it was often hard for consumers to tell which was which.

Read more:
How should I add sunscreen to my skincare routine now it’s getting hotter?

At last, SPF arrives to guide consumers

In the 70s, two Queensland researchers, Gordon Groves and Don Robertson, developed tests for sunscreens – sometimes experimenting on students or colleagues. They printed their ranking in the newspaper, which the public could use to choose a product.

An Australian sunscreen manufacturer then asked the federal health department to regulate the industry. The company wanted standard definitions to market their products, backed up by consistent lab testing methods.

In 1986, after years of consultation with manufacturers, researchers and consumers, Australian Standard AS2604 gave a specified a testing method, based on the Queensland researchers’ work. We also had a way of expressing how well sunscreens worked – the sun protection factor or SPF.

This is the ratio of how long it takes a fair-skinned person to burn using the product compared with how long it takes to burn without it. So a cream that protects the skin sufficiently so it takes 40 minutes to burn instead of 20 minutes has an SPF of 2.

Manufacturers liked SPF because businesses that invested in clever chemistry could distinguish themselves in marketing. Consumers liked SPF because it was easy to understand – the higher the number, the better the protection.

Australians, encouraged from 1981 by the Slip! Slop! Slap! nationwide skin cancer campaign, could now “slop” on a sunscreen knowing the degree of protection it offered.

How to pick the right sunscreen when you’re blinded by choice

How about skin cancer?

It wasn’t until 1999 that research proved that using sunscreen prevents skin cancer. Again, we have Queensland to thank, specifically the residents of Nambour. They took part in a trial for nearly five years, carried out by a research team led by Adele Green of the Queensland Institute of Medical Research. Using sunscreen daily over that time reduced rates of squamous cell carcinoma (a common form of skin cancer) by about 60%.

Follow-up studies in 2011 and 2013 showed regular sunscreen use almost halved the rate of melanoma and slowed skin ageing. But there was no impact on rates of basal cell carcinoma, another common skin cancer.

By then, researchers had shown sunscreen stopped sunburn, and stopping sunburn would prevent at least some types of skin cancer.

There’s a serious ethical problem with some sunscreen testing methods – and you’re probably not aware of it

What’s in sunscreen today?

An effective sunscreen uses one or more active ingredients in a cream, lotion or gel. The active ingredient either works:

• “chemically” by absorbing UV and converting it to heat. Examples include PABA (para-aminobenzoic acid) and benzyl salicylate, or

• “physically” by blocking the UV, such as zinc oxide or titanium dioxide.

Physical blockers at first had limited cosmetic appeal because they were opaque pastes. (Think cricketers with zinc smeared on their noses.)

With microfine particle technology from the 90s, sunscreen manufacturers could then use a combination of chemical absorbers and physical blockers to achieve high degrees of sun protection in a cosmetically acceptable formulation.

Read more:
Research Check: should we be worried that the chemicals from sunscreen can get into our blood?

Where now?

Australians have embraced sunscreen, but they still don’t apply enough or reapply often enough.

Although some people are concerned sunscreen will block the skin’s ability to make vitamin D this is unlikely. That’s because even SPF50 sunscreen doesn’t filter out all UVB.

There’s also concern about the active ingredients in sunscreen getting into the environment and whether their absorption by our bodies is a problem.

Sunscreens have evolved from something that at best offered mild protection to effective, easy-to-use products that stave off the harmful effects of UV. They’ve evolved from something only people with fair skin used to a product for anyone.

Remember, slopping on sunscreen is just one part of sun protection. Don’t forget to also slip (protective clothing), slap (hat), seek (shade) and slide (sunglasses).
