In the outer reaches of our Solar System, 5.7 billion kilometres from the Sun, lies the dwarf planet Pluto. Smaller than Australia, it is an icy world of mountains, glaciers and craters where the average temperature is –232°C.

Five moons orbit Pluto – Styx, Nix, Kerberos, Hydra and Charon. Of these, Charon is the largest. Unlike most other planetary systems, it exists in a “binary system” with its parent body, meaning they both orbit a point in space between the two.

Much mystery still surrounds Pluto and its moons. But in new research published in Nature Communications today, a team led by astronomer Silvia Protopapa from the Southwest Research Institute in the United States announced they’ve found carbon dioxide and hydrogen peroxide on Charon’s surface.

The findings, based on data from NASA’s James Webb Space Telescope, offer vital clues about how our favourite not-planet/planet system was formed.

What is Charon?

Scientists first discovered Charon in 1978 when they were studying the orbit of Pluto.

Charon is kind of like Pluto’s smaller twin. It is just over 1,200 kilometres wide – about half the size of Pluto, which makes it the largest known satellite relative to its parent body in our Solar System. Pluto itself is already small when compared to our Moon, with Pluto being about two-thirds the size and one-sixth the mass of Earth’s satellite. Charon’s mass is about one-eigth that of Pluto’s.

Charon and Pluto have an unusual orbit. While Charon goes around Pluto, Pluto also spins around a central point. They act almost like a double dwarf planet. This is unlike the Moon and Earth, where the Moon goes around us, and we don’t really change our position.

This is one reason why Pluto is no longer considered a planet, but is now labelled a dwarf planet. Its orbit with Charon means Pluto has not cleared its orbit, or has become the gravitational boss. This is the criteria Pluto failed in the planetary checklist.

The composition of Charon

In 2015, NASA’s New Horizons became the first spacecraft to explore Pluto and its moons up close after a nine-year journey from Earth. It showed Charon is composed of a variety of chemicals.

It is a very cold moon, rich in water ice. But it also contains ammonia and a wide variety of carbon-based compounds. Charon is also believed to have cryovolcanoes – areas that erupt ice instead of magma like on volcanoes on Earth.

Charon’s composition is different to Pluto’s and that of other objects beyond Neptune, which are dominated by nitrogen and methane ice.

The new detection of carbon dioxide and hydrogen peroxide on Charon can give valuable insight into how various processes interact on these trans-Neptunian objects.

Carbon dioxide is always a key molecule to understand – it tells us a lot about the history of an object.

In the case of Charon, it is believed the carbon dioxide comes from below the icy surface and has been exposed through asteroids and other objects hitting the moon and creating craters which reveal the fresh underground surface.

James Webb Space Telescope does it again

Scientists were able to detect carbon dioxide on Charon thanks to observations from the groundbreaking James Webb Space Telescope. Launched in 2021, this space telescope has a large mirror, six-and-a-half metres wide, which makes it very powerful and sensitive.

It can “see” in the infrared – colours of light our eyes and most telescopes on Earth can’t detect. The infrared is a key type of light for finding various molecules present on other objects – from planets to stars, galaxies and more.

To find these compounds, the telescope uses a technique called spectroscopy. The colours of light are broken up into individual colours, like breaking up white light into a rainbow. Each element or molecule has its own colour signature, like a fingerprint.

These new observations of Charon showed the signatures of carbon dioxide and hydrogen peroxide, along with the other previously known water ice.

Vital clues to an ancient mystery

The formation of Charon is a scientific mystery. One of the leading theories is that it formed in a similar way to our Moon. According to this theory, some 4.5 billion years ago, a large object in the Kuiper Belt – the area where Pluto and Charon live – collided with Pluto and part of it broke off and formed into Charon.

It also could be that Pluto and Charon were two objects that collided, and then got stuck orbiting around each other.

Understanding the composition of Charon helps advance our understanding of how it formed. In this sense, the discovery of carbon dioxide and hydrogen peroxide represents an important step forward. Importantly, this can also give clues not only about Charon, but other objects out near Pluto.

More insights into Charon will help us understand this distant part of our Solar System – and the strange worlds that lie there.

Fees for medical specialists are going up faster than Medicare rebates, leading to a bigger gap for patients to pay.

Recent data from the Australian Institute of Health and Welfare shows that in the first quarter of this year, Medicare rebates covered just over half (52%) of the total fees. This is down from 72% two decades ago, and the lowest proportion on record.

Doctors can charge what they like, while the government determines the Medicare rebate. The difference between the two, or the gap, is what impacts patients. For GPs, the government provides an incentive for doctors to bulk bill, but there’s no such incentive for other specialists.

Doctors blame large gap payments on rebates being too low, and they’re partly right. After adjusting for inflation and increasing demand, the average dollar amount one person receives in Medicare rebates annually dropped from A$349 to $341 over the past decade.

But this is only a part of the problem. When many people can’t afford hundreds (if not thousands) of dollars for essential specialist care, we need to look at why fees are so high.

How do specialists set their fees?

Although general practice is technically a speciality, when we talk about medical specialists in this article, we’re talking about non-GP specialists. These might include paediatricians, oncologists, psychiatrists and dermatologists, among many others.

In determining fees, specialists consider a combination of patient-level, doctor-level and system-level factors.

Patient characteristics, such as the complexity of the patient’s medical condition, may increase the price. This is because more complex patients may require more time and resources.

Specialists, based on their experience, perceived skill level, or ethical considerations, may charge more or less. For example, some specialists report they offer discounts to certain groups, such as children or pensioners.

System-level factors including the cost of running a practice (such as employing staff) and practice location also play a role.

Problems arise when prices vary considerably, as this often signals limited competition or excessive market power. This holds true for medical services, where patients have little control over prices and rely heavily on their doctors’ recommendations.

In recent research, my colleagues and I found fees varied significantly between specialists in the same field. In some cases the most expensive specialist charged more than double what the cheapest one did.

Doctor characteristics influence fee-setting

My colleagues and I recently analysed millions of private hospital claims from 2012 to 2019 in Australia. We found the wide variation in fees was largely due to differences between individual doctors, rather than factors such as patient complexity or the differences we’d expect to see between specialties.

Up to 65% of the variance in total fees and 72% in out-of-pocket payments could be attributed to differences between doctors in the same field.

To understand what doctor-level factors drive high fees, we looked at data from a representative survey of specialists. We found older specialists have lower fees and higher rates of bulk billing. Practice owners tended to charge higher fees.

We also found doctors’ personalities affect how much they charge and how often they bulk bill patients. Doctors who scored more highly on the personality trait of agreeableness were more likely to bulk bill patients, while those who scored more highly on neuroticism tended to charge higher fees.

What we couldn’t show is any evidence fees were associated with competition.

Effects on patients

This is not a competitive market. On the contrary, it has high entry restrictions (long training requirements) and a limited supply of specialists, particularly in rural and remote areas. Meanwhile, patients’ access is controlled by the need for referrals which expire, generally after a year.

Patients are often unable to shop around or make informed decisions about their care due to a lack of information about the true cost and quality of services.

For private hospital services, the fee structure is complicated by the fact that several providers (for example, surgeon, anaesthetist, assistant surgeon) bill separately, making it difficult for patients to know the total cost upfront.

Despite efforts to introduce price transparency in recent years, such as through the government’s Medical Costs Finder website, the system remains far from clear. Reporting is voluntary and the evidence is mixed on whether these tools effectively reduce prices or increase competition.

All of this contributes to high and unpredictable out-of-pocket costs, which can lead to financial strain for patients. About 10.5% of Australians reported cost was a reason for delaying or avoiding a specialist visit in 2022–23.

This raises important questions about equity and the sustainability of Australia’s universal health-care system, which is built on the principle of equitable access to care for all citizens.

What can be done?

Patients can take steps to minimise their costs by proactively seeking information. This includes asking your GP for a range of options when you’re referred to a specialist. Note the referral from your GP can be used for any other doctor in the same specialty.

Similarly, ask the specialist’s receptionist what the fee and rebate will be before making an appointment, or for a detailed quote before going to hospital. Shop around if it’s too high.

But responsibility doesn’t only lie with patients. For example, the government could seek to address this issue by increasing investment in public hospital outpatient care, which could boost competition for specialists. It could also publish the range of fees compared to the rebate for all Medicare-billed consultations, rather than relying on voluntary reporting by doctors.

Price transparency alone is not enough. Patients also need quality information and better guidance to navigate the health-care system. So continued investment in improving health literacy and care coordination is important.

If things don’t change, the financial burden on patients is likely to continue growing, undermining both individual health outcomes and the broader goals of equitable health-care access.

Two of the dominant players in New Zealand’s supermarket sector – Foodstuffs North Island and Foodstuffs South Island – have failed in their quest to officially join forces.

In a decision announced yesterday, the Commerce Commission declined to green-light the merger between the two cooperatives. The watchdog said it was not satisfied the move wouldn’t result in reducing competition in the New Zealand grocery sector.

But it needs to go further.

Instead of adjudicating on a merger, the commission should be given the power to break up the two Foodstuffs entities themselves. Local competitors, such as the Warehouse or others, should also be encouraged to ensure shoppers get the best deals.

Seeking a dominant union

In their December 2023 application, the two cooperatives said they would be more efficient and have greater buying power as one entity.

Foodstuffs North Island and Foodstuffs South Island argued the levels of competition in the supermarket sector would not decrease with the merger.

The two entities admitted to already sharing information and not meaningfully competing against each other in the same regions. This is set to continue with the failure of their application to merge.

Multiple submissions to the Commerce Commission, such as those from academics Tim Hazeldine and Robert Hamlin, claimed Foodstuffs’ unwillingness to compete with each other demonstrated a worrying precedent in New Zealand.

The Grocery Action Group also claimed the two Foodstuffs’ entities breached consumer trust because one is an actual cooperative (Foodstuffs South Island), while 93% of Foodstuffs North Island’s shares are owned by four people who do not own physical stores.

This is an issue, as they continue to claim they are both owner-operated cooperatives, when only Foodstuffs South Island legally is.

Further submissions by industry bodies representing suppliers and Consumer NZ included concerns a merger would reduce competition.

The concentrated supermarket sector

International research has long found competition is good for prices.

But New Zealanders have less choice of where to do their grocery shop compared with other developed nations. The sector is dominated by the Foodstuffs entities – which include Pak’nSave, New World and Four Square – and Australian-based Woolworths (which also owns Fresh Choice).

In New Zealand there is one supermarket for every 12,871 people, while in Germany there is one for every 3,009, and one for every 5,563 in Ireland, a similar-sized island nation. New Zealand supermarkets generate the highest annual revenue per store among developed markets at US$27.9 million, versus $19.56m in the United States, $7.7m in Germany and $17.02m in Ireland.

Foodstuffs North Island’s current market share is just over 40%. Merging with Foodstuffs South Island would have increased the single entity’s national market share to 55%.

The Grocery Commission, set up in response to the Commerce Commission’s study of the supermarket sector, recently released its first annual report.

It found there was no meaningful competition in the sector and more competition was needed. It further highlighted that profit margins had increased since the 2022 market study.

Challenging mergers

New Zealand is not the only country where regulators are pushing back against supermarket mergers.

In August, the US Federal Trade Commission brought an emergency injunction blocking the merger between supermarket giants Albertsons and Kroger.

The US$24.6 billion proposal would have been the largest supermarket merger in US history, with a combined market share of just under 20%.

The court case, which is yet to be decided, included revelations of price gouging by Kroger. Albertsons is Kroger’s primary price competitor, meaning absorbing them would remove competition and the need to compete on price.

The Albertsons-Kroger merger would substantially lessen competition and trigger price increases.

In the United Kingdom, the Competition and Markets Authority blocked a 2019 merger between Asda and Sainsbury’s. At the time, the authority said shoppers would be worse off if the two supermarkets, with a combined market share of 31%, merged.

Time to break up the sector further

As we see in foreign markets, the push for market power to return higher profits is likely to continue. But when those businesses provide basic necessities, such as food, more competition is required, not less.

The proposed merger process has provided greater insight into the structure of Foodstuffs North Island and Foodstuffs South Island – including where the two organisations already work together.

As argued in some of the submissions to the Commerce Commission, the next logical step would be to separate Pak’nSave from the other Foodstuffs brands and encourage nationwide competition. If broken up, the new companies should be renamed to create separation from the current brands.

The Commerce Commission’s decision on the proposed Foodstuffs merger reinforces concerns about competition in New Zealand’s supermarket sector, as does the report from the Grocery Commission and the earlier grocery sector study.

If competition creates better prices for consumers, then splitting up New Zealand’s concentrated supermarket sector is the logical next step.

Lisa Asher made four submissions against the merger to the Commerce Commission in her capacity as an academic.

Qatar Airways has announced plans to buy a 25% minority stake in Virgin Australia from its owner, US private equity firm Bain Capital.

The two airlines have already had a strong relationship as “codeshare partners” since 2022. Codesharing is where airlines agree to sell seats on each other’s flights. This new announcement, however, is a big step up.

All of this will, of course, be subject to approval from both Australia’s Foreign Investment Review Board and the Australian Competition and Consumer Commission (ACCC). But there could be a range of winners if it goes ahead.

Perhaps most importantly for Australian travellers, the move means Virgin Australia will be able to compete as it once did on long-haul international routes.

This is because a proposed “wet lease” agreement – in which one airline provides full aircraft, crew and relevant services to another – could see Virgin Australia start operating its own flights from Brisbane, Melbourne, Perth and Sydney to Doha as early as mid-2025.

It’s also a win for Bain Capital, which had been trying to offload some of its stake in the airline after acquiring it in crisis in 2020.

So with the prospect of a renewed international foothold for Virgin Australia, could we soon see more competition – and real consumer benefits – on the “Kangaroo Route” between Australia and Europe?

Clearer skies for Qatar?

As you might remember, Qatar Airways’ previous attempts to expand in Australia haven’t always gone smoothly.

Today’s announcement comes little more than a year after Transport Minister Catherine King controversially blocked a request by Qatar to double the number of flights its state-owned airline Qatar Airways was allowed to fly into major Australian airports.

Given the intense public backlash to this decision, it’s possible a renewed application by Qatar would have been more successful. A large expansion of flights by Turkish Airlines was later quietly approved.

But this new deal may diminish the need to try again. By wet-leasing wide-body aircraft so Virgin Australia can operate its “own” long-haul routes to Doha (connecting into Europe), Qatar will effectively bypass the need to get government approval for the additional flights.

What will putting the interests of Qantas ahead of Qatar Airways cost? $1 billion per year and a new wave of protectionism of legacy carriers

The ‘Kangaroo Route’ still needs more flights

Back in 2023, my calculations suggested Qatar’s application to expand should have been approved. Capacity on the Kangaroo Route was only back to 70% of pre-COVID levels. That meant the major players operating flights – including the Qantas–Emirates alliance – could charge significantly more than before the pandemic.

Using the latest flight schedule data, we can show that the capacity between Australia and the Middle East is still 17% below what it was before the pandemic. If Virgin Australia’s proposed long-haul re-entry goes ahead, we could see much more capacity on these routes, and a formidable challenger to the Emirates–Qantas arrangement.

What will putting the interests of Qantas ahead of Qatar Airways cost? $1 billion per year and a new wave of protectionism of legacy carriers

Likely a win for Virgin and Qatar

It’s easy to see why Virgin and Qatar might be excited. The deal will extend Virgin Australia’s reach – and that of its frequent flyers – into Europe and other destinations via Doha. But this goes both ways, and could also mean more demand on its domestic network.

Similarly, the additional flights into Doha will feed Qatar Airways’ network, an airline that seems to be going from strength to strength.

Despite historical troubles at Doha’s main airport, Qatar Airways is now one of the world’s largest airlines. It has once again been ranked as the world’s best airline by the independent air transport rating organisation Skytrax.

Both airlines were also keen to point out benefits of the partnership they said would go beyond additional services and increasing competition in the Australian market.

These include the potential to work together towards various sustainability initiatives and on developing Western Sydney’s aviation ecosystem, providing exciting new opportunities for employment and training.

Not yet a done deal

However, they’re still a long way from the finishing line. Whether this deal will actually materialise remains to be seen.

It is worth noting this is not the first time Virgin Australia has been part-owned by an airline in the Middle East. Before Virgin Australia’s collapse into administration in April 2020, Etihad held a 21% equity stake.

Further, it remains to be seen what aircraft Virgin Australia will actually get access to and how the service will be perceived. Qatar Airways is guaranteed a transaction win through the wet-lease, without taking on the brand and profit risks of operating these services.

How much concern this will stir at Qantas also remains to be seen, but one thing is clear. Project Sunrise – Qantas’ plan to bypass the Middle Eastern hubs and connect Australia directly with Europe – could soon become much more important.

Emirates is unlikely to emerge as the winner of this move, now set to face increased competition not only on services connecting Australia with the Middle East, but also across its broader network through Dubai.

Qatar Airways acquiring a stake in Virgin Australia will also create interesting dynamics within the Oneworld Alliance, in which both Qantas and Qatar Airways are key partners. There are certainly interesting times ahead.

Humanity’s rapacious consumption is more than Earth and its climate can handle, which is driving an ecological crisis. Australians are the worst offenders per person due to our excessive resource use.

At the same time, people in some parts of the world lack the material goods to meet their basic needs, while many people in wealthier societies have more than enough to live comfortably.

That’s where the concept of “sufficiency” can help. It’s a policy approach that avoids demand for energy, materials, land and water, and ensures wellbeing for all humans, while staying within planetary boundaries.

What does this mean in practice? Workplaces closer to homes, public transport systems that everyone can access and afford, and reducing cars on the road. Sharing building spaces. Providing enough housing, goods, clothing and food to meet our needs, but not exceed them.

What is ‘sufficiency’?

Sufficiency is a whole-of-government approach that aims to create the structural change needed for societies to consume less overall. It also seeks to ensure wellbeing for all people, not just the affluent.

It requires reassessing our needs and the ways they can be met. It requires policies with firm targets and supporting infrastructure, to foster change in individuals and businesses.

Sufficiency is not the same as efficiency, which is about producing more of a good or service with less energy, time or materials – often achieved through technological innovation.

Unlike sufficiency, efficiency does not avoid or reduce overall demand to a point where humanity is operating within Earth’s limits. Nor does it explicitly focus on reducing inequality.

Most governments around the world are yet to adopt sufficiency as a defining policy feature. But progress is being made.

A concept gaining momentum

In 2022, a major report by the Intergovernmental Panel on Climate Change highlighted the need for sufficiency measures in the built environment sector, to contain global warming to 1.5°C.

It said up to 61% of global building emissions could be mitigated by 2050 if a range of measures were implemented, including “[s]ufficiency policies that avoid the demand for energy and materials”.

France enshrined sufficiency in its energy law in 2015. French energy authorities say sufficiency measures, such as lower energy use in households and less travel, may enable emissions cuts of 10% by 2030.

And in March this year, 83 organisations in Europe released a manifesto urging the European Union to make sufficiency central to its agenda.

I co-founded the Paris-based World Sufficiency Lab, which researches and promotes the sufficiency concept. Here, I outline how sufficiency policies could be applied in Australia in three key areas.

1. Clothing

Australians are the world’s biggest textile consumers, buying an average 56 new items per person each year.

In response, the federal government’s Seamless scheme has proposed a levy of 4 cents per item applied to clothing importers and Australian manufacturers. The money would be spent on measures to reduce clothing waste.

The scheme falls far short of measures in some other jurisdictions.

The EU’s much stronger textile strategy, for example, aims to ensure that, by 2030, all clothes for sale are long-lived and recyclable. It would also make producers responsible for a product over its entire life, including when it becomes waste.

This strategy is moving closer towards a sufficiency approach, and the goal of reducing the overall production and purchase of clothes.

2. Food

Each year, Australians waste around 7.6 million tonnes of food, equal to around 312 kilograms per person.

The National Food Waste Strategy aims to halve food waste by 2030, largely by focusing on food rescue.

But these policies are not strong enough to tackle the scale of the problem. A German study last year found limiting global warming to 1.5°C requires limiting the carbon footprint of our diets by 84% by 2050.

A sufficiency approach would go further to tackle over-consumption – perhaps even through direct government intervention.

For example, in 2020, China brought in anti-food waste laws. Under the measures, restaurants can charge an extra fee to customers leaving excessive uneaten food. Restaurants that consistently waste large quantities of food may also be fined.

3. Transport

Transport was responsible for 21% of Australia’s emissions last year.

A sufficiency policy in transport would aim to bring about structural change. For example, it would shift thinking away from the traditional assumption that mobility equates to wellbeing.

It would embrace digital alternatives to travel, such as online meetings. It would also ensure urban planning that locates people and places closer together – and provides good public transport infrastructure.

As the European sufficiency manifesto has outlined, governments should also tackle aviation emissions by, for example, prohibiting air travel where there is a train alternative and introducing a frequent flyer levy.

In line with the sufficiency concept, efforts to reduce transport emissions must prioritise affordable, accessible transport systems for the disadvantaged and vulnerable.

Making sufficiency mainstream

Sufficiency is about more than saving the planet. It can tackle global inequality, improve our wellbeing and reduce the cost of living.

But many countries, including Australia, are yet to include sufficiency as a mainstream policy lever.

This must change. Time is running out to address many of Earth’s most pressing problems. But creating societies with sufficiency at their core means getting governments on board.

Generation Z has been called “the sustainability generation”.

Born between 1997 and 2013, 58% of this consumer cohort seek to buy products that are sourced sustainably. Australian Gen Zs say they are willing to pay more for brands that have a positive impact on society.

Yet, at the same time, we have witnessed the meteoric rise of ultra-fast fashion from online, direct-to-consumer retailers such as Shein, Temu and Boohoo. Shein alone generated US$32.5 billion (A$48.3 billion) in revenue in 2024 – a 43% increase from 2022.

There are complexities surrounding Gen Z’s shopping habits and how these often fail to align with their values.

On one hand, they covet a brand-new clothing item that is markedly more affordable when purchased from an ultra-fast fashion brand. On the other hand, they are aware of the environmental harms.

What explains this cognitive dissonance?

Caring about the environment …

Different from their predecessors, Gen Z has grown up with climate change as an urgent issue. Being chronically online means these concerns are not limited to their local environment.

Recent research revealed a pattern of stronger emotions of fear, guilt and outrage about the impacts of climate change among younger people, compared with older groups. These emotions could well be a driver of their activism and engagement with climate change.

They expect companies – those they buy from and work for – to prioritise sustainability in their business practices.

However, Gen Z crave more engaging ways to receive sustainability-related content. This is a worthy consideration for key players in the fashion industry.

… vs the temptation of fast fashion

Gen Z consumers are plugged into social media trends that appear with every scroll and swipe on TikTok and Instagram. Social media have spiked cultural trends that accelerate fast fashion.

Influencers promote “reps” (slang for replicas) and “dupes” (duplicates): cheaper, imitation versions of high-end fashion items. This is a way to democratise luxury by normalising “superfake” products and making luxury more accessible to a broader audience.

Social media tactics such as “hauls” and get-ready-with-me (“GRWM”) videos entice Gen Zs to get stuck on the treadmill of overconsumption. The idea is for content creators to show off massive amounts of new, trendy clothing. This in turn fuels the desire for consumers to continuously buy what they are seeing online – in bulk.

Fast fashion giants such as Zara and H&M have based their business models on translating what is on catwalks into cheap clothing, produced in mass quantities. Now, ultra-fast fashion brands such as Shein speed up the production cycle, the trend churn and consequently the volume.

Having seven trending items, over two high-quality outfits, makes more sense to Gen Z consumers in the digital age.

The cost-of-living crisis plays a part too. A recent survey of Australian Gen Zs revealed at least 77% are experiencing money concerns.

The biggest demographic to pull back on spending due to economic stress are 18–26-year-olds. Young people typically earn the lowest wages and enjoy less job security. These financial constraints are challenging to Gen Zs seeking to consume more sustainably.

Fast fashion becomes a cheap option for them to stay trendy without breaking the bank.

The ‘attitude–behaviour gap’

Gen Z are Shein shoppers, haul lovers, micro-trend followers, and repeat outfit shamers. This stands starkly against their eco-conscious values.

While this seems hypocritical, it is what is referred to as the attitude–behaviour gap – the incongruence between what people say and what they actually do. This is a phenomenon noted across multiple generations.

The attitude–behaviour gap has been widely documented in social psychology and ethical consumerism studies. These underscore that consumer intentions are not reliable predictors of behaviour.

Even ethically minded consumers do not always walk their talk. But we can’t expect individual consumers to be entirely responsible for things like the carbon footprint of fast fashion, or the exploitation of workers in factories.

The clothing industry lacks transparency in business practice and Gen Z consumers often lack information about the products they are buying.

The responsibility to shop sustainably should not fall solely on consumers, but on governments, policymakers and corporations to be more ethical.

Unsurprisingly, 88% of Gen Z shoppers do not trust companies’ sustainability claims.

What does this mean for the sustainability movement?

Despite climate change being a major stressor for Gen Z, the attitude–behaviour gap continues to exist when it comes to hunting for a new outfit.

Being bombarded with persuasive tactics from brands and influencers, the ease of access to new items at the click of a button, and the allure of affordable pricing amid a cost-of-living crisis makes it very difficult for even the most committed Gen Z consumer to buy ethically.

The fashion industry is one of the biggest dangers to the environment in terms of its carbon and raw material footprint, and truckloads of clothing ending up in landfills.

While most young people know and respect Greta Thunberg’s environmental mission, she is not the one they are watching on TikTok or liking on Instagram.

It is time to re-engage with social media content creators in different ways that educate consumers, promote responsible behaviour and advocate for changed regulations and business practices. This might include tried-and-true tactics such as influencer endorsements and haul videos that are refocused on more sustainable options – like online second-hand retailers.

The emergence of “underconsumption core” on TikTok in recent months, as well as “deinfluencing”, where influencers call on their followers to buy less, is promising.

While sustainable clothing has a “bad rap” for being expensive, fast fashion brands are trying to adapt by offering options such as H&M Conscious. Any fashion offering must be convenient, accessible and trendy to capture Gen Z’s attention and wallet.

Governments around the world are battling to regulate big tech companies. As the world becomes more interconnected, people are increasingly aware of the vast, often negative, influence these companies play in our lives.

More generally, many corporations extend their power over their employees to their non-work lives.

Josh Bornstein is a lawyer specialising in employment and labour relations law. His new book, titled Working for the Brand: how corporations are destroying free speech, examines the problematic reach of the corporate hand into the private sphere.

He joined the podcast to talk about his book and more.

On big tech companies, Bornstein highlights the kind of damage these companies can cause:

These rampaging large monopolies, out of control monopolies, who as well as changing our culture in many ways have visited many harms, in the form of harm to democracy as well as brutalising culture inciting violence. They are not properly regulated, and we’re seeing the state now trying to wrestle with the problems they are causing. Whether they can be reined in is a question I pose in the book, because they are so enormous.

Bornstein demonstrates how easily companies can silence their employees:

When we go to work, are we engaging in an exchange of labour for income or are we unwittingly forfeiting our right to participate in democracy? Let’s take media companies. [They] are, they tell us, designed to fulfil an important democratic function, which is to hold the powerful to account and to present the truth. There is a disturbing tendency, particularly in commercial media, to impose NDAs on employees not just after they’ve had a terrible sexual harassment dispute but at the point that they sign an employment contract.

There is a real tension between saying we’re in favour of demonstrating the truth and holding the powerful to account while silencing our staff.

But, he says, he’s encouraged by the work of some government leaders:

I’ve heard recently the South Australian Premier talk about imposing a duty of care on big tech towards consumers, and I think that would be a game changer because a duty of care would require big tech companies to prevent harm and a failure to comply with that obligation would result in lawsuits and significant loss of revenue. That sort of approach, a multifaceted approach, which just doesn’t require one regulator playing Whac-A-Mole. But multifaceted regulation, I think is critical when the companies are so powerful.

Bornstein laments the corporatisation of universities but notes their lack of total power, which he sees in other areas:

Universities have been corporatised. It’s well known now. They’ve become large commercial juggernauts headed up by vice-chancellors on commercial CEO salaries, $1.8 million, which is an extraordinary salary for someone working in a not-for-profit institution. They’re a not-for-profit institution, but in many ways now ape corporate profit-seeking entities, and they’ve brought in directors and managers that now apply the usual corporate imperatives, including corporate brand management.

They do try and suppress the academic freedom and speech rights of employees. But it’s an area where they’re not always successful, and that distinguishes them from the rest of the labour market.

As many as 50 million people now have a record of their menstrual cycle on their personal devices.

But how much should we rely on our period tracker for reliable and accurate information about menstruation and fertility?

Some apps are free, and some make you pay. All are part of a booming industry known as “femtech”. But evidence about the apps’ accuracy and quality suggest they don’t always help us better understand our bodies.

Here’s what period-tracking apps can – and can’t – tell you about your cycle.

How do period trackers work?

Period trackers ask users to enter a large amount of personal data, including period dates, sexual activity, mood, symptoms (such as bloating or cramps), and energy levels. Based on this self-reported data, the apps use algorithms to make predictions.

These include when your period will arrive, how long it will last, the day you’ll ovulate and your “fertile window”, usually about 3–7 days per cycle when conception is more likely.

Some apps rely entirely on the length of the menstrual cycle to make their predictions (known as calendar-based apps).

Others also use biometric data, such as daily body temperature, cervical mucous consistency or hormone levels in the urine. These bodily changes directly relate to ovulation, and can therefore increase the accuracy of ovulation predictions.

But many apps don’t include this data in their algorithms, even if they record it. And many apps aren’t transparent about how they formulate predictions, and whether they are applicable to most users.

Challenging the 28-day cycle norm

The textbook menstrual cycle has been understood as 28 days, with ovulation occurring at day 14, or 14 days before the next period.

But research since the 1960s has shown the length of menstrual cycles can vary between individuals and from cycle to cycle. Now, recently published data from period tracking apps reveals just how varied they can be.

Collaborations between researchers and app companies mean we have access to millions of cycles from hundreds of thousands of people.

Popular fertility apps are engaging in widespread misuse of data, including on sex, periods and pregnancy

These studies have shown only 13–16% of women have a 28-day cycle, and only 13% ovulate on day 14. There is also considerable variation month to month. For example, one study showed cycle length varied for more than half of women by five or more days.

These findings call into question our definition of a “normal” menstrual cycle. Despite this, many calendar-based apps still predict ovulation as 14 days before the estimated period start date, meaning they may be inaccurate for most people.

Should I trust app predictions to prevent pregnancy?

Some people use period app predictions for fertility planning, either to increase their chances of conception or as a contraceptive tool.

Although data examining apps’ ability to prevent pregnancy is limited, existing studies have found a fail rate of 7.2–8.3%. This rate of unintended pregnancy is similar to that of condoms with typical use.

However, studies often excluded participants if their cycle length varied somewhere between three and seven days. This means their effectiveness for preventing pregnancy is less certain for many people whose cycle varies.

The reliability of these findings also depends on how consistently users logged their data, which is hard to verify. Many of these studies were also funded and authored by the companies that own the app studied, so results should be interpreted with caution.

Do period trackers help women learn about their bodies?

As our research has shown, apps often market themselves as empowering users, enhancing self-knowledge and control. Many claim to fill the gap in women’s health research.

But one recent study found people who use period-tracking apps are no more likely to have basic knowledge of their cycles than those who don’t use them. Another study found apps improve knowledge, but only slightly.

If the app’s prediction is wrong, users may doubt their own body rather than the app’s accuracy. Women have reported feeling stressed and anxious when the dates don’t match up.

The quality of information on these apps can also be highly variable. Evidence-based information can help destigmatise and normalise common symptoms such as vaginal discharge. But when good information is available, it is often locked behind a pay wall or very generic.

Some apps may also endorse non-scientific beliefs, such as cycle syncing (planning workouts and diets based on menstrual cycle phases), seed cycling (eating different combinations of seeds in an attempt to balance hormones) and astrology.

So should I use a period tracker to monitor my cycle?

Period trackers are a profitable industry, collecting personal information on a global scale. The companies behind these apps are not bound by medical legislation, but instead by the rules of the app store that hosts them.

Provided you enter dates correctly, apps can give you an instant record of your menstrual cycles. This can be very helpful for a number of reasons, such as discussing your menstrual history with a doctor, estimating your due date if pregnant or helping inform a diagnosis of menopause.

Predictions can also be useful as an idea of when your period may arrive. But be aware they could be wrong. And given the mounting evidence showing just how much menstrual cycle length can vary, don’t trust your app to tell you if your cycle is not normal.

While major irregularities can be cause for concern, irregular cycles are common and don’t always indicate an issue. If you are concerned, it’s best to speak to your doctor.

Artificial intelligence (AI) has begun to permeate many facets of the human experience. AI is not just a tool for analysing data – it’s transforming the way we communicate, work and live. From ChatGP through to AI video generators, the lines between technology and parts of our lives have become increasingly blurred.

But do these technological advances mean AI can identify our feelings online?

In our new research we examined whether AI could detect human emotions in posts on X (formerly Twitter).

Our research focused on how emotions expressed in use posts about certain non-profit organisations can influence actions such as the decision to make donations to them at a later point.

Using emotions to drive a response

Traditionally, researchers have relied on sentiment analysis, which categorises messages as positive, negative or neutral. While this method is simple and intuitive, it has limitations.

Human emotions are far more nuanced. For example, anger and disappointment are both negative emotions, but they can provoke very different reactions. Angry customers may react much more strongly than disappointed ones in a business context.

To address these limitations, we applied an AI model that could detect specific emotions – such as joy, anger, sadness and disgust – expressed in tweets.

Our research found emotions expressed on X could serve as a representation of the public’s general sentiments about specific non-profit organisations. These feelings had a direct impact on donation behaviour.

Detecting emotions

We used the “transformer transfer learning” model to detect emotions in text. Pre-trained on massive datasets by companies such as Google and Facebook, transformers are highly sophisticated AI algorithms that excel at understanding natural language (languages that have developed naturally as opposed to computer languages or code).

We fine-tuned the model on a combination of four self-reported emotion datasets (over 3.6 million sentences) and seven other datasets (over 60,000 sentences). This allowed us to map out a wide range of emotions expressed online.

For example, the model would detect joy as the dominant emotion when reading a X post such as,

Starting our mornings in schools is the best! All smiles at #purpose #kids.

Conversely, the model would pick up on sadness in a tweet saying,

I feel I have lost part of myself. I lost Mum over a month ago, Dad 13 years ago. I’m lost and scared.

The model achieved an impressive 84% accuracy in detecting emotions from text, a noteworthy accomplishment in the field of AI.

We then looked at tweets about two New Zealand-based organisations – the Fred Hollows Foundation and the University of Auckland. We found tweets expressing sadness were more likely to drive donations to the Fred Hollows Foundation, while anger was linked to an increase in donations to the University of Auckland.

Ethical questions as AI evolves

Identifying specific emotions has significant implications for sectors such as marketing, education and health care.

Being able to identify people’s emotional responses in specific contexts online can support decision makers in responding to their individual customers or their broader market. Each specific emotion being expressed in social media posts online requires a different reaction from a company or organisation.

Our research demonstrated that different emotions lead to different outcomes when it comes to donations.

Knowing sadness in marketing messages can increase donations to non-profit organisations allows for more effective, emotionally resonant campaigns. Anger can motivate people to act in response to perceived injustice.

While the transformer transfer learning model excels at detecting emotions in text, the next major breakthrough will come from integrating it with other data sources, such as voice tone or facial expressions, to create a more complete emotional profile.

Imagine an AI that not only understands what you’re writing but also how you’re feeling. Clearly, such advances come with ethical challenges.

If AI can read our emotions, how do we ensure this capability is used responsibly? How do we protect privacy? These are crucial questions that must be addressed as the technology continues to evolve.

On October 1, Claudia Sheinbaum will take an oath, receive a sash and become the first female president of Mexico.

Sheinbaum is the former mayor of Mexico City and a climate scientist who received a Nobel Prize in 2007 as part of the Intergovernmental Panel on Climate Change.

She takes over a government utterly dominated by the ruling Morena party. Despite being barely a decade old, Morena has exploited pervasive public disillusionment with the more established parties. It has a majority in both chambers of the national congress and will hold 24 of 32 state governorships.

Morena has always been closely associated with its founder, the outgoing president, Andrés Manuel López Obrador, and his personalised, populist approach to politics.

Presidents are strictly limited to a single six-year term by the Mexican constitution. López Obrador says he will now retire to his ranch, far removed from the halls of power in Mexico City. However, some observers expect he will continue to wield power within Morena, the power behind Sheinbaum’s throne.

While López Obrador built a winning political machine closely tied to his own charisma, it is unclear whether it is built to last. His policies ensured his popularity, but often did so in ways that might weaken governments in the future.

Sheinbaum thus begins her term in an extremely powerful position. At the same time, her power is often called into question, assumed to be not really her own. And she faces the difficult task of tackling some of the most intractable issues in the country, which her predecessor either skirted or exacerbated.

Organised crime and disorganised policy

One of the most pressing issues has dogged Mexican leaders for years: the high rates of homicides and other violent crimes.

Mexico’s violence is often attributed to organised crime groups, but the situation is far more complicated. The violence is fuelled by a variety of factors. This includes collusion between officials and criminal groups, as well as the heavy-handed police and military responses to crime.

Since President Felipe Calderón declared an ineffectual war on narcotrafficking in 2006–08, every leader has taken their own approach to this issue. López Obrador came to office promising abrazos no balazos (hugs not slugs), aiming to address the underlying causes of crime through social programs. He even declared the war over in 2019. In practice, though, anti-crime measures continued.

Homicide rates remained high throughout his term, while extortion of businesses by criminal groups increased by 60%, partly because of perceived government permissiveness towards less violent crime.

In this year’s election, the main candidates and parties appeared to be largely out of new ideas. Insecurity remains an urgent problem, but there were few real plans for better managing it.

Sheinbaum campaigned on the relative safety of Mexico City during her tenure as mayor, but the capital is a very different place to other parts of the country. Some wealthy cities are able to purchase a degree of safety through investments in police and private security (and perhaps tolerating extralegal security measures), but this doesn’t offer a paradigm for the whole country.

Organised crime and the war on narcotrafficking still dominate the headlines, but this masks other alarming patterns of violence.

Femicide, or the murder of women because they are women, remained at persistently high levels during López Obrador’s tenure, but received little attention from him. Investigations suggest that high levels of impunity for femicide can encourage other forms of violence.

The military becomes more public and private

On October 1, Sheinbaum becomes the supreme commander of the armed forces in Mexico. However, she assumes command of a military with more autonomy and power than at any other point in recent history.

For some time, activists and scholars have been sounding the alarm about the dangers of increased militarisation in Mexico – that is, the takeover of civilian roles by the military.

With the war on narcotrafficking in 2006, the military took on civilian roles related to security, such as policing. López Obrador expanded this range of roles tremendously, using the military to build major infrastructure projects.

López Obrador also awarded substantial concessions to the military. Having constructed several train lines as part of the Mayan Train megaproject in southeastern Mexico, for example, military businesses will now take over the management of the transport system, as well as connected airports, hotels and other tourism facilities.

Other militaries in Latin America have extensive economic portfolios, but these are usually seen as a relic of the authoritarian past. Once a government affords such public roles and economic autonomy to the military, it is very hard to claim them back.

This increased participation of the military in various aspects of public life raises troubling questions about transparency and justice.

For example, the military has provided little access to information on the Mayan Train project, such as environmental impact statements. When I conducted interviews, locals reported being pressured and intimidated by the military over the expropriation of land for infrastructure projects.

Sheinbaum’s biggest challenges

Observers note that Sheinbaum rarely deviates from supporting López Obrador and his policies. This is sometimes taken as a sign of weakness, with Sheinbaum cast as a kind of dutiful daughter to the patriarch of Morena.

However, this risks oversimplifying – in a heavily gendered way – the political context in which Sheinbaum has risen to power. She has little to gain by distancing herself from her powerful predecessor before she has even taken office. (Adopting his regional accent, though, is another story).

The question of how Sheinbaum steps out from the shadow of López Obrador is an important one. But this has less to do with whether he goes quietly into retirement and more to do with the difficulties he leaves behind.

Presidential terms in Mexico are long (six years). Historically, this has afforded new presidents time to distance themselves from their predecessors (who often play a role in lifting them up) to develop their own agendas.

Sheinbaum’s real challenge will be to develop policies that meaningfully tackle violence and insecurity, while managing a military with more autonomy and a shifting portfolio of interests.

Many other issues are also clamouring for attention. Sheinbaum would do well to start repairing some of the relationships that López Obrador damaged, such as between the president and the press, academia, Indigenous communities and the country’s irrepressible feminist movements.

On October 1, Jimmy Carter, the United States’ 39th president, turns 100.

Carter’s longevity is notable. In 2024, centenarians make up just 0.003% of the US population, and 78% of them are women.

Carter is the first US president to reach the landmark age and the longest-living former US president by some margin. His 77-year marriage to Rosalynn Carter, who died last year, was also longer than most presidents’ lives.

It has now been almost 44 years since Carter lost office, easily defeated by a Republican, Ronald Reagan, who first promised to “make America great again”.

As a one-term president, a fate that Joe Biden will also share, Carter does not rank highly in polls of great presidents. One former speechwriter, perhaps harshly, even labelled it the “passionless presidency”.

But presidents are defined by more than their presidency – a lesson that may comfort Biden as he heads into enforced retirement. As Carter turns 100, it’s an apt time to reflect on a unique life after the oval office: one with relevance to key global issues of our time.

A tough presidency

As president from 1976 to 1980, Carter struggled to deal with congress, a sign of his political inexperience.

His presidency was marked by stagflation: a toxic mix of high inflation, stagnant growth and persistent unemployment.

His poll numbers were low and his social reform efforts fell short.

Tensions in the Middle East further eroded his support. The 1979 Iranian Revolution led to sharp increases in energy costs and the infamous hostage crisis. The Soviet invasion of Afghanistan contributed to the atmosphere of chaos in Carter’s final year in office.

Carter’s defeat in a landslide in 1980 was humiliating. A post-political life in obscurity might have been expected.

The opposite occurred. Carter’s long post-presidency arguably achieved more than his presidency, which became bogged down in economic malaise and foreign policy reversals.

Success overseas

As president, Carter’s greatest achievements came in his efforts to implement a human rights-based foreign policy. He continually put his own political wellbeing on the line to pressure US allies to improve their human rights records, as well as returning the Panama Canal from US control.

Arguably his greatest achievement was the Camp David peace accords, which established “normal and friendly relations” between Israel and Egypt after 31 years of warfare and hostility. Historian Richard Perlstein described Carter’s efforts:

he knew just when to risk a scathing remark and when to say nothing at all; when to horse-trade and when to hold fast, ever reassessing the balance between the visionary and the pragmatic.

Once free from the pressures of being president, Carter’s skills in foreign affairs flourished, working assiduously for human rights and peace, especially in the Middle East.

In 2002, he won the Nobel Peace Prize for his “decades of untiring efforts” to find peaceful solutions to international conflict. Carter is one of only four US presidents to win the prize and the only one to win it after leaving office.

Recently, the Carter Center in Atlanta, another of his legacies, called for a ceasefire in Gaza and noted that Carter would be on the plane to try and secure one if his health permitted it.

Today, Carter’s Middle Eastern efforts – while certainly not perfect, given the intractability of the challenges – stand the test of time and remain especially relevant.

Ahead of the curve

Post-White House, the Carters (they were very much a partnership) were ahead of their time on many issues.

Building on important environmental work as president, Carter installed the first solar panels at the White House and saved millions of acres in Alaska from development. This was long before climate change was widely recognised.

For more than 40 years, Carter was also a stalwart of Habitat for Humanity, a charity that builds free houses for needy working families. In the early 1980s, he gave the group “national visibility”, an outcome that helped it expand internationally. This was well before housing affordability became a major political issue.

Carter also strove to remove the stigma associated with mental illness, again long before such efforts were common.

A former peanut farmer from Georgia, Carter’s post-presidency is distinctive in other ways.

Most former presidents retire to live in luxury in Washington DC, New York or on private estates in the country. Carter, however, went back to Plains, Georgia, the small town (population 776) where he and Rosalynn had grown up.

Carter has decreed that upon his death, the “modest” ranch house that he built there in 1961 will be gifted to the US National Park Service. The planned museum will showcase the house’s ordinariness; it is a typical example of the brick homes built by millions of Americans after World War II.

Strong Christians, the Carters lived for decades among the citizens of Plains, going to church and mingling with the community. When Rosalynn died in 2023, the funeral was held at the local Baptist church, not in Washington DC. The entire town turned out to watch the procession. Presidents, first ladies, governors and senators were in the congregation, but only pastors, family and friends spoke.

Carter’s survival is also notable. He has been in “end-of-life” hospice care at home for almost two years. In the US, the average stay in such care is 70 days.

Carter’s family have publicised his condition partly to break taboos about death and provide support for the millions around the world whose loved ones are in hospice care. Although frail, the former president has no underlying conditions and his family report that he is looking forward to voting for Kamala Harris on November 5.

A man who lived the first 40 years of his life in a racially segregated southern state, with most adult black people unable even to vote, has witnessed tremendous social change.

Carter may not have been the best politician, but there is a fundamental decency about him that stands as an important legacy. Even his opponents could agree on that.

According to James Fallow, a former aide who wrote an important account of the Carter administration, the 39th president had admirable personal qualities. Fallow described Carter as “disciplined, funny, enormously intelligent and deeply spiritual”.

At a time of fake news and record low levels of trust in politicians, this “politician with principles” is worth remembering.

The rise of artificial intelligence (AI) has triggered concern about potentially detrimental effects on humans. However, the technology also has the potential to harm animals.

An important policy reform now underway in Australia offers an opportunity to address this. The federal government has committed A$5 million to renewing the lapsed Australian Animal Welfare Strategy. Consultation has begun, and the final strategy is expected in 2027.

While AI is not an explicit focus of the review, it should be.

Australians care about animals. The strategy could help ensure decision-makers protect animals from AI’s harms in our homes, on farms and in the wild.

Will AI harms to animals go unchecked?

Computers are now so developed they can perform some complex tasks as well as, or better than, humans. In other words, they have developed a degree of “artificial intelligence”.

The technology is exciting but also risky.

Warnings about the risks to humans include everything from privacy concerns to the collapse of human civilisation.

Policy-makers in the European Union, the United States and Australia are scrambling to address these issues and ensure AI is safe and used responsibly. But the focus of these policies is to protect humans.

Now, Australia has a chance to protect animals from AI.

Australia’s previous Animal Welfare Strategy expired in 2014. It’s now being revived, and aims to provide a national approach to animal welfare.

So far, documents released as part of the review suggest AI is not being considered under the strategy. That is a serious omission, for reasons we outline below.

Powerful and pervasive technology in use

Much AI use benefits animals, such as in veterinary medicine. For example, it may soon help your vet read X-rays of your animal companion.

AI is being developed to detect pain in cats and dogs. This might help if the technology is accurate, but could cause harm if it’s inaccurate by either over-reporting pain or failing to detect discomfort.

AI may also allow humans to decipher animal communication and better understand animals’ point of view, such as interpreting whale song.

It has also been used to discover which trees and artificial structures are best for birds.

But when it comes to animals, research suggests AI may also be used to harm them.

For example, it may be used by poachers and illegal wildlife traders to track and kill or capture endangered species. And AI-powered algorithms used by social media platforms can connect crime gangs to customers, perpetuating the illegal wildlife trade.

AI is known to produce racial, gender and other biases in relation to humans. It can also produce biased information and opinions about animals.

For example, AI chatbots may perpetuate negative attitudes about animals in their training data – perhaps suggesting their purpose is to be hunted or eaten.

There are plans to use AI to distinguish cats from native species and then kill the cats. Yet, AI image recognition tools have not been sufficiently trained to accurately identify many wild species. They are biased towards North American species, because that is where the bulk of the data and training comes from.

Algorithms using AI tend to promote more salacious content, so they are likely to also recommend animal cruelty videos on various platforms. For example, YouTube contains content involving horrific animal abuse.

Some AI technologies are used in harmful animal experiments. Elon Musk’s brain implant company Neuralink, for instance, was accused of rushing experiments that harmed and killed monkeys.

Researchers warn AI could estrange humans from animals and cause us to care less about them. Imagine AI farms almost entirely run by smart systems that “look after” the animals. This would reduce opportunities for humans to notice and respond to animal needs.

Existing regulatory frameworks are inadequate

Australia’s animal welfare laws are already flawed and fail to address existing harms. They allow some animals to be confined to very small spaces, such as chickens in battery cages or pigs in sow stalls and farrowing crates. Painful procedures (such as mulesing, tail docking and beak trimming) can be legally performed without pain relief.

Only widespread community outrage forces governments to end the most controversial practices, such as the export of live sheep by sea.

This has implications for the development and use of artificial intelligence. Reform is needed to ensure AI does not amplify these existing animal harms, or contribute to new ones.

Internationally, some governments are responding to the need for reform.

The United Kingdom’s online safety laws now require social media platforms to proactively monitor and remove illegal animal cruelty content from their platforms. In Brazil, Meta (the owner of Facebook and WhatsApp) was recently fined for not taking down posts that had been tagged as illegal wildlife trading.

The EU’s new AI Act also takes a small step towards recognising how the technology affects the environment we share with other animals.

Among other aims, the law encourages the AI industry to track and minimise the carbon and other environmental impact of AI systems. This would benefit animal as well as human health.

The current refresh of the Australian Animal Welfare Strategy, jointly led by federal, state and territory governments, gives us a chance to respond to the AI threat. It should be updated to consider how AI affects animal interests.

Mount Everest (also known as Chomolungma or Sagarmāthā) is famously the highest mountain in the Himalayas and indeed on Earth. But why?

At 8,849 metres above sea level, Everest is around 250m taller than the other great peaks of the Himalayas. It is also growing by about 2mm each year – roughly twice as fast as it has been growing on average over the long term.

In a new paper published in Nature Geoscience, a team of Chinese and English scientists say Everest’s anomalous height and growth have been influenced by the Arun River, which flows through the Himalayas. They argue that the river’s course changed around 90,000 years ago, eroding away rock that was weighing Everest down – and the mountain has bounced up in response, by somewhere between 15 and 50m.

The authors make a case for the river’s contribution, but they acknowledge the “fundamental cause” of the peak’s size is the tectonic processes that create mountains. To understand what’s going on, we need to understand the forces that made the Himalayas in the first place, and the movements that let them grow so high.

The Tibetan blob

In the 19th century, British surveyors showed that the southern boundary of the Himalayan mountains accurately describes an arc that aligns precisely with a small circle on Earth. This is pretty amazing.

The only rational way it can be explained is if we have the Eurasian tectonic plate to the north, the Indian plate to the south, and in between a viscous mass (Tibet) spreading southwards as it slowly collapses under the force of gravity.

Deep down, the Tibetan plateau must be like hot syrup, with a cold crust at the higher levels displaying faults and earthquakes as it is pushed around by the slow northerly advance of the Indian tectonic plate. The exact nature and depth of this hot syrup is a matter of some debate, with geologists comparing it variously to creme brûlée and a jelly sandwich.

Overall, the collision of India and Eurasia is marked by a “megathrust fault”, where the Indian plate is gradually sliding under the Eurasian plate. The whole megathrust doesn’t move at the same time. In general, it lurches forward bit by bit in a series of “thrust earthquakes”.

Where the spreading mass of Tibet makes contact with India, we see a narrow band of these thrust earthquakes. It is what happens in that narrow band that ultimately determines the elevation of the world’s highest mountain.

How mountains rise (and fall)

Why is the Tibetan Plateau, to Everest’s north, so flat, whereas mountains abound next to this narrow band of quakes, where the collapsing mass couples with the advancing Indian subcontinent?

The answer lies in the way that the mass of a mountain is supported.

Imagine a mountain as a pile of rubble on a thin plastic table. There is no inherent strength in the tabletop, so it sags downwards and the pile of rubble sinks. Much like an iceberg, only a part of the mass sticks up.

Νow imagine a thicker strong plate at the edge of the table. Here the pile of rubble is supported by the flexural strength of the plate, so it can rise much higher above the surface. So here mountains can be far higher. This is what happens where one tectonic plate slides over another, as the downgoing plate creates a stronger region.

Naturally there is a balance. When the movement of tectonic plates causes earthquakes, the mountain tops can shatter and giant avalanches will move the fallen rock into the adjacent river systems.

The fall of this rubble may reduce the mountains’ absolute height, and also its relative height compared to neighbouring valleys – though this will depend on how efficiently rivers move the debris downstream.

In turn, when this rocky mass is moved away downstream, the upstream areas will be somewhat lighter. In our plastic table model, we might expect the table surface would bow down less and rubble peak rise a smidgen higher.

This is what the new research argues, but fundamentally it is earthquakes that push mountains higher. When the megathrust ruptures, where the tectonic plates meet, up the mountains go – though how far up they go depends on the strength of the supporting rock beneath.

What’s special about Everest?

The crucial question (as indeed the authors recognise) is why does Everest stand out?

The boundary between collapsing Tibet and advancing India is defined by a giant megathrust fault. Some parts of this fault have not broken for a very long time, perhaps several centuries or more. It is likely that a lot of strain has accumulated in these areas, and when they finally break, the result will be catastrophic.

However, the part of the megathrust beneath Everest appears to break routinely, perhaps once or twice per century. The last big earthquake there partly involved an existing rupture.

With each break, it is likely that Everest grows a little higher. Hence it’s no wonder that Everest is able to maintain its superiority in comparison to peaks in quieter parts of the megathrust.

As the new research suggests, rogue rivers may well play a role in Everest’s size – but the bulk of the mountain’s greater height still seems likely due to the pattern of quakes along the Himalayan fault.

The difficulty for the scientists involved is how to separate the individual contributions to height from different factors. One is erosional rebound, as the new research suggests, but there are also tectonic processes such as movement on the Main Central Thrust, or slow creep on the South Tibetan Detachment Fault beneath which Earth’s highest mountain has been exhumed.

There is nothing to disclose.

From today, October 1, new changes to Australian laws around vaping products should make it easier for adults to get low-dose nicotine vapes as a tool to quit smoking.

Pharmacists will be able to supply vapes containing up to 2% nicotine without a prescription following a patient consultation.

People aged under 18 will still need a prescription to access vapes, while anyone seeking a vape containing a higher dose of nicotine will similarly still need a prescription.

So how did we get here? And are these changes going to make it easier for people to access nicotine vapes to help them quit smoking?

A series of changes to vape laws

Evidence suggests vapes containing nicotine can help people quit smoking, and may be more effective than other nicotine replacement therapies. For people who haven’t been successful with other methods, using vapes to quit smoking may be a reasonable option to try.

Vaping is certainly not without risks. However, vapes emit far lower levels of harmful chemicals compared to cigarettes, so the health risks of vaping are likely much less than those of smoking.

Since 2012, Australians have needed a prescription to access vapes that contain nicotine, while nicotine-free vapes were allowed to be sold under the same conditions as tobacco products in most of Australia.

However, many vapes that were sold under the guise of being nicotine-free contained undeclared nicotine. Few Australians obtained a prescription, even when using vapes to quit smoking.

Spurred by reports of a rapid increase in vaping among young people, health minister Mark Butler commenced a series of changes to federal laws with the goal of stamping out recreational vaping.

These reforms commenced in 2024 with a complete ban on the importation of disposable vaping products from January 1. From March 1, general retailers such as tobacconists were permitted to run down their existing stock of vapes, but could not legally restock. Individuals were also no longer allowed to import vapes for personal use, even if they had a prescription.

On July 1, further changes banned general retail sales of vapes regardless of their nicotine content. Only pharmacies could supply vapes on prescription for therapeutic purposes.

From July 1 there were also changes to the types of vapes pharmacies can supply – all flavoured vapes other than tobacco, mint or menthol flavour were banned. The idea is these vaping products will be less attractive to young people.

As of today, changes to federal laws allow pharmacists to supply low-dose nicotine vapes without a prescription.

There may be some barriers

The changes beginning today are intended to balance access to vapes for adults for therapeutic use with the need to protect young people from taking up vaping by maintaining health practitioner oversight of supply. Removing the prescription requirement for some patients should also free up GP time and reduce costs.

People with a high nicotine dependence, such as those who smoke heavily, may need a higher dose of nicotine to effectively manage the withdrawal symptoms when quitting smoking. The 2% limit for over-the-counter supply matches concentration limits imposed in some other countries, such as the United Kingdom.

Another benefit of the change is that it fits the government’s intention of not penalising individuals for using vapes. Unauthorised possession of a prescription-only medicine is a serious offence that can potentially attract large fines and jail terms in some jurisdictions. There were concerns about whether this was the most appropriate classification for vapes when cigarettes remain widely available without similar restrictions and penalties.

However, patients seeking to buy vapes directly from a pharmacy may still encounter some barriers. Many pharmacists have not welcomed the removal of the prescription requirement for several reasons.

First, the amendment to remove the prescription requirement was announced without a formal public consultation process and with a very short time frame to implementation (about three months).

While pharmacists have been supplying vapes on prescription for some time, the primary responsibility has been with the prescribing doctor. Some pharmacists have expressed concern about whether their professional indemnity insurance will cover supply without a prescription, because vapes are not approved as medicines. Others may object to supplying vapes because they see it as like selling cigarettes.

There are also practical issues for some pharmacies, such as having enough staff and a private space to provide appropriate counselling. Under the new laws, a pharmacist must consult with the patient to confirm a vape is clinically appropriate before supplying it, and get their consent to be supplied a product that’s not an approved medicine.

Given these concerns, some pharmacies may decide to continue only supplying vapes to adults with a prescription. Others may also choose not to stock vapes.

There may also be differences in access around the country because states and territories can impose further restrictions. For example, the Tasmanian parliament is considering a bill that, if passed, will retain the current restrictions for supply of vapes in Tasmania (a prescription needed for adults and no supply allowed for under 18s).

Meanwhile, Western Australia has announced it will also retain the current prescription requirement. Other states may follow too.

Nicotine vapes are one of several options

Vapes are one of a range of smoking cessation products available over-the-counter in pharmacies, including nicotine patches, mouth sprays, gums and lozenges.

From today, a new option called cytisine, a non-nicotine smoking cessation medicine, may also be available without a prescription in some pharmacies.

So people seeking support to quit smoking should talk to their pharmacist or Quitline about the full range of options available to find the best one for them.

Have you ever asked your child how school was today, only to be told it was “boring”?

It’s a conversation sadly all-too-familiar to a lot of parents. Many are left wondering why and what they can do to help.

It’s important to understand why your child may be feeling bored at school. Here are some possibilities to consider.

Not every aspect of school is engaging

Boredom at school isn’t uncommon. Remember, a child’s learning journey is jagged, not linear. Their learning may progress quickly during some periods, and less so at other times. Sometimes they will be bored.

Research has found Year 9 students reported feeling bored during nearly half of class time, on average, while younger students report feeling bored during about a third of class time.

Our own research, which involved surveying 412 students in Year 10 about their emotions, revealed boredom was the most commonly reported emotion among participants.

This is concerning because students need to be emotionally invested to learn well.

As we argued in our paper, it’s possible there’s a need for some teachers to develop more stimulating lesson plans, and work more with students to find ways to motivate and engage them. Collecting feedback and working with their students to minimise classroom boredom could help some teachers.

Young people are growing up in an era where – thanks to technology – boredom in spare time is rare. This can be quite challenging for teachers, who generally want to encourage their students to reflect, ponder and contemplate.

But research has found closer student-teacher relationships, creating safe and supportive classrooms, and linking learning to real-world contexts relevant to students can often mitigate negative emotions like boredom.

The greater the control the student has over their learning – and the better they see the value of it – the more motivated they’re likely to be.

But lesson content is only part of the picture.

Is your child bored some or all of the time?

If your child is feeling bored in just one class, or one subject, then it could be the lesson content.

But if your child is consistently complaining that all classes and all school is boring – and you’ve noticed their grades are declining – there may be more to consider, such as:

• the possibility of an underlying learning difficulty, such as dyslexia (which relates to reading) or dyscalculia (which relates to maths and numbers)
• the possibility of hearing or vision impairment
• the possibility your child is “gifted”, meaning they learn much faster than their peers.

If you suspect any of these, talk to your GP, and to your child’s teacher.

Is boredom masking other emotions?

When children say they are bored, they might be struggling to identify and express more complex feelings such as sadness or anxiety.

So it’s worth considering if there are friendship issues happening in the playground, or if there is something else going on emotionally for your child.

These stressors can occupy your child’s thoughts in the classroom, taking attention away from learning.

By helping children to understand and articulate their emotions, we can provide them the tools to manage these experiences more effectively.

Some schools offer programs that help children identify their emotions and learn social, emotional and behavioural regulation skills.

Children with good social emotional skills are likely to do better on a range of interpersonal and academic outcomes, which can also benefit parents, teachers and the school in general.

So what should parents do?

Talk openly with your child. Ask more specific questions about their day, instead of just “how was school?”. Instead, you can try questions like:

• what was the most interesting thing you learned at school today?
• can you tell me about something you enjoyed doing at school today?
• was there anything that made you feel frustrated or bored today?
• what do you wish you could change about your day?
• who did you play with today?
• if you were the teacher for the day, what would you do differently?
• what feedback did you receive from your teacher on your work today?

Find out what they mean when they say they’re bored at school, and when they feel bored.

Consider having them assessed for possible learning difficulties, and their eyes and ears checked.

Find out if there any problems with friends, or possible anxieties lurking below the surface.

If your child is particularly high achieving academically, discuss this with the school. Your child may be eligible for further assessment and extension support.

Find ways to relate what your child is learning in school to their own lives and interests.

Consider how you can strengthen your child’s relationship with their teacher, and talk to the teacher, too. They might be able to make simple adjustments to support your child’s motivation and engagement.

Since the end of his three-term New York City mayoralty in 2013, Michael Bloomberg hasn’t shied away from public attention. Presidential ambitions and global climate policy advocacy have kept him busy.

But what is shaping up to be one of the most ambitious projects of the 82-year-old billionaire’s public life is not happening on the highly visible stages of national and international politics. It is unfolding in the stereotypically humdrum halls of city government.

Through Bloomberg Philanthropies – the vehicle for his personal and corporate giving – he has advanced an array of initiatives for city government leaders. The organisation is now providing funding and technical support to around 700 city governments across 150 countries – including Wellington City Council’s new digital community engagement tools.

In the process, Bloomberg has created for himself a historically unique and highly influential quasi-public position.

As a kind of “world’s mayor”, he promotes a burnished version of his self-styled image while New York City mayor: eking out efficiency and effectiveness gains within city government through assiduous managerial control and better use of evidence.

But Bloomberg’s inroads into global local government also raise important questions about the reliability of philanthropy over the long term – and its democratic legitimacy.

A ‘perfect match’?

Bloomberg has described partnerships between philanthropists and government as a “perfect match”. “Philanthropists,” he notes, “have resources that governments need for innovation, and governments have powers that philanthropists need for solving problems.”

City governments are especially short of resources. Most face growing demands but diminishing financial capacity. They often contend with indifferent or actively hostile state and national governments, as well as the slow progress of international agreements.

Without the necessary resources and capabilities, they struggle to address a range of problems felt intensely at the local scale, from unaffordable housing to climate change.

Enter the “government innovation program” from Bloomberg Philanthropies, a pro-bono system of capacity-building initiatives for city governments. It has been growing for over a decade, tentatively at first, and concentrating initially on the United States.

Since 2017, more than 275 mayors and 400 city officials, mainly American, have attended year-long intensive training by the Bloomberg-funded City Leadership Initiative at Harvard University. Last year, one-third of American cities were reportedly led by a participant in the program.

But the “Bloomberg world” – as one of several city officials we interviewed described it – has expanded and diversified over time. It is now one of the most influential global players in urban policy dialogue and practice.

Soft power

Bloomberg Philanthropies’ “Mayors Challenge” competition was initially specific to the US, Europe, Latin America and the Caribbean.

But in 2021 it began to expand globally, receiving entries from 631 cities in 99 countries. Fifteen winning cities, including Wellington, were each awarded US$1 million (NZ$1.57 million) and substantial technical support.

The organisation has established around 40 “innovation teams” within city governments. And its certification system for data-driven decision making has become something city leaders now strive toward. There are over 60 “certified cities” in the US, with plans to expand abroad.

Bloomberg-funded initiatives are now announced with such consistency it would be hard for a city government practitioner to avoid them.

In just one month recently, 20 mayors signed a public declaration of their adherence to data-driven decision making, as part of their induction into the second round of the Bloomberg Philanthropies’ City Data Alliance.

Ten cities won US$1 million each to implement sustainable transport projects; 60 city leaders attended a workshop run by the Bloomberg Harvard City Leadership Initiative on making “procurement an engine of innovation”; and the tenth Bloomberg CityLab summit was announced for Washington DC.

There have been examples of philanthropic foundations using their financial heft as a form of hard power to push city governments around – Detroit’s post-bankruptcy “Grand Bargain”, for example, or New Orleans’ post-hurricane rebuild.

But Bloomberg Philanthropies favours a soft-power model. It gauges and anticipates the needs of city governments, and supports them as they align toward shared goals and methods. They “gently steer”, according to one city government official we interviewed.

Democratic legitimacy

The difference between pushing and steering is evident in Bloomberg Philanthropies’ tendency to avoid advocating for particular policy solutions. Any perception of political interference could dampen cities’ willingness to partner.

Instead, the organisation’s expanding reach and growing indispensability rest on providing know-how: offering access to technical assistance, funding and networks to implement “best process”, informed by better data.

In this sense, its role is one of “meta-governor” – adjudicating, promoting and embedding the practices of good governance.

But while Bloomberg’s philanthropy seems welcomed by city governments, it raises important political issues. Philanthropic funding can be appealing because it comes with fewer strings attached. However, it also comes without democratic accountability. And there are risks in relying on funding streams subject to the whims of billionaires.

As ever, the big question about philanthropy is not whether it is useful to those receiving it, but rather should it even exist? Faced with a forbidding fiscal outlook and mounting policy challenges, it’s a question city governments might not have the luxury of asking.

Directed by Akira Kurosawa and starring Toshiro Mifune and Takashi Shimura, 1954’s Seven Samurai (七人の侍, Shichinin no Samurai), is a technical and creative watershed of the action genre and world cinema.

In 2021, Time Out magazine placed it at number three on its list of the best action movies of all time. The film was also named the greatest foreign-language film ever in BBC’s 2018 poll, which surveyed 209 critics across 43 countries.

Set in 16th-century feudal Japan, Seven Samurai follows a beleaguered village that hires seven warriors to defend against marauding bandits. It culminates in one of the greatest and most lengthy action sequences ever put to screen.

Beyond just the magnificence of the film itself – which has undergone an extensive restoration and will have a cinema re-release this month – is Kurosawas’s meticulous approach to the production.

Meticulous production

Before Seven Samurai, Kurosawa had risen to international prominence through his film Rashomon (羅生門) (1950), winning the prestigious Golden Lion at the 1951 Venice Film Festival.

Following its success he became more ambitious with his film choices.

Next came an adaptation of Fyodor Dostoevsky’s 1869 novel The Idiot (白痴) (1951), and Ikiru (生きる) (1952), a loose adaptation of Leo Tolstoy’s 1886 novella The Death of Ivan Ilyich.

For Seven Samurai, his following film, he went to new lengths with his preparation.

For every speaking character, Kuroswara wrote an individual dossier including specific details about clothes, foods, family history and other personal details. Directors such as Michael Mann and Quentin Tarantino have since incorporated this approach to their own productions, citing Kurosawa as their influence.

Part of the film’s appeal is how Kurosawa brings a breadth of vision to the past without dismissing deeper aspects of the farming community he depicts. Within this samurai epic are memorable and poignant moments of comedy, domestic drama and tragedy among the training of the farmers into effective samurai swordsmen.

Kurosawa’s idea for the story was pulled from historical annals, and the film was preceded by a lengthy period of historical research.

He had wanted to make a samurai epic for several years, but was unable to find material he felt would sustain a feature film. Producer Sôjirô Motoki discovered samurai in the “Warring States” period of Japan would volunteer to stand guard at peasant villages in exchange for food and lodging.

Kurosawa liked the idea and felt having local farmers trained as samurai to fight for their own land spoke profoundly to postwar Japan.

A new approach to filmmkaing

In Australia, Seven Samurai initially played at the 1956 Melbourne International Film Festival and wowed audiences in ways it has continued to wow new audiences throughout the past 70 years.

One enthusiastic Kurosawa fan was Australian director George Miller. There had always been a lot of Seven Samurai in the Mad Max movies. Compare the sparse dialogue, the restless camera movements, the invasive close-ups and natural sounds overlapped with the baroque soundtrack.

Mad Max: Fury Road is a more straightforward rethinking of Seven Samurai with the plot itself sharing a clear overlap of villagers required to learn the skills to fight off lawless rogues for their land.

This was the first film in which Kurosawa used multiple cameras, so he could shoot from different angles and directions without stopping the actors every time he wanted a different shot. Kurosawa would subsequently use a multiple-camera setup on every one of his following films.

Longer lenses (most notably the telephoto lens) were used in an unprecedented way with the camera photographing great detail, such as facial expressions and horses’ hooves through the teeming rain and mud splatter.

The epic action sequence to conclude the film is simply masterful. No film since has matched its cinematic physicality on a kinetic level. In Seven Samurai, Kurosawa demonstrated a new style of fight choreography that has never been surpassed.

Refusing to shoot the peasant village at Toho Studios, Kurosawa had a complete set constructed at Tagata on the Izu Peninsula, Shizuoka.

Because of the wet and sludge of the milieu, death is never glamorised or decorative. When they die, they die in the cold mud.

Focus on the individual

The great appeal of the film and why it arrived as a revelation was how Kurosawa presented an action film based on individuals rather than bureaucratic or political ambitions.

It is also worth considering how the film positions itself within postwar Japan as characters reassert themselves and their community without the support of the army.

Ultimately, this is a story about people in power helping those less fortunate. The final moments of the film reinstates this by demonstrating the survival of the farmers and farming community over lionising the individual heroes. People in power have a duty to help those less fortunate.

“The farmers have won. Not us,” the leader of the samurai group, Kambei Shimada (島田勘兵衛) (Takashi Shimura), declares to end the film.

It is hard to think of an action film that resonates so poignantly on an emotional and visceral level with audiences as Seven Samurai, even 70 years later. Its significance and legacy remain unparalleled.

Anyone who has driven in Toronto during rush hour can tell you how busy the roads can get. In the face of traffic gridlock and rising commute times, Ontario Premier Doug Ford recently announced his government is exploring the idea of building a roughly 50-kilometre tunnel beneath the 401, North America’s busiest highway.

That announcement came days after the Ford government said it is considering banning new cycling lanes if they result in reductions in car lanes.

Confronted with escalating housing costs and reduced affordability, the government proposed reforms to provincial planning legislation to speed up construction on Greenbelt sites in what many described as weakening local control over the quality of development and its potential environmental impacts.

If the provincial government continues with this agenda, the weight of evidence in planning research points to long-term decreases in the quality of life for Ontario residents. Here’s why.

Issues with car-oriented planning

First, new highways bring more cars and eventually result in the same or even worse gridlock. They also contribute to air pollution and climate change. Therefore, to accommodate new growth, governments need to consider alternative modes of transport.

Second, car-oriented development inherently produces more urban sprawl, making it difficult to accommodate walking, cycling and public transit that are known to have important environmental and health benefits.

When more highways are built, there is usually a desire to separate residential subdivisions from traffic, resulting in more dispersed amenities that are difficult to reach without a car. That can be expensive. Given the rising cost of living, it is not unreasonable to expect that car ownership will become increasingly costly for more people.

This means that not only could Ontario residents face more urban sprawl, but many people will also find it difficult, and time-intensive, to get to where they need to go.

This is not an anti-car argument. There will still be many cars in the future and some of it will be from new growth, but progressive planning policies would help create alternatives.

North America’s car-centred planning

Ford’s emphasis on cars is reminiscent of another time, coincidentally often called the Fordist period by urban researchers — so named after the mass production of Ford automobile plants that became a symbol of the economy and suburban expansion of the times.

At its height between the 1950s and ’70s, original Fordist urban planning focused on the automobile, separating land designated for workplaces, retail stores and homes, and developing large scale subdivisions at the suburban fringe. North America’s heavy car reliance is an artefact of this development model.

Planning decisions have long-term consequences.

In part arising from the social activism of the 1960s, planning began to place more focus on environmental issues. In the ’70s and ’80s, this pertained to the protection of environmentally significant areas; the Niagara Escarpment plan was one important achievement of this movement.

In the 1990s, it became clear, however, that environmental protection would eventually be challenged, and fail, unless development itself was going to use less land and become more co-ordinated.

This was the height of the smart growth movement that emphasized the need for greenbelts to constrain suburban sprawl, and concentrate development into higher density neighbourhoods and more walkable growth centres connected by public transit.

Building better

Public health, the environment and growing pressures on municipal finances are all important reasons to build communities that are more walkable, bikeable and transit-oriented.

However, the Ontario government’s recent announcements do not clearly indicate how prioritizing cars would address health, environmental and municipal fiscal issues.

Connecting communities with better rail service, for example, and putting some restrictions on automobile traffic would be an investment made in preparation for a future where gas prices are expected to rise. Furthermore, there will likely be mounting pressures to reduce greenhouse gas emissions as governments face the rising costs of natural disasters and a changing climate.

The Ontario government’s approach to infrastructure development hearkens back in time when urban planning did not incorporate urban planning ideas around environmental protection and smart growth. It’s also an approach without sufficient investments in critical community infrastructure, such as affordable housing.

Hallmarks of the original Fordist period were investments in community centres, schools, transit infrastructure as a social service, and yes, affordable housing. Although the governments at the times focused on car-reliant urban development, there was still significant investment in social infrastructure.

That is not the case today. Governments are pushing for the kinds of policies used in the past that are the very reason why citizens are so reliant on cars today — but without the social infrastructure that was arguably a redeeming feature of original Fordist urban planning.

The Ontario government’s approach is not consistent with the current evidence on best practice planning. Car use and low-density sprawl will continue and perhaps even accelerate because new and proposed policies make it attractive to do so.

The future would likely be more congested, more polluted, and we would see more loss of agricultural and environmentally significant lands. Ontario’s policies of more auto dependence are heading in the wrong direction, and would reduce the quality of life of Ontario residents in the future.

The Albanese government, in a fresh strike against the supermarkets, has announced it will work with the states to reform regulations to help boost competition by opening more sites for new stores.

The government also is providing about $30 million to the Australian Competition and Consumer Commission to assist it to undertake more investigations and enforcement in the supermarket and retail sectors.

This follows the ACCC’s launch of legal action against Coles and Woolworths for alleged dodgy discounting practices.

Prime Minister Anthony Albanese and Treasurer Jim Chalmers said in a statement present planning and zoning restrictions, including on land use, “are acting as a barrier to competition by inhibiting business entry expansion”.

“They potentially allow land banking, preventing competition and pushing up prices in our local communities.”

The government said it was “taking decisive action to help consumers get fairer prices” from supermarkets.

“Misconduct in the supermarket and retail sector is unfair, unacceptable and makes cost-of-living pressures worse for Australians.”

The government stressed its latest measures followed a series of actions it has taken. Last week it released its mandatory food and grocery code for consultation. It has also banned unfair contract terms and increased penalties for breaches of competition and consumer law, and is reforming the merger provisions.

Land banking, planning regulations used to stifle competition

The interim report of the Australian Competition and Consumer Commission’s year-long supermarkets inquiry released on Friday identified land use restrictions, zoning laws and planning regulations as challenges for aspiring operators attempting to compete with the major chains.

The Commission said it had also received submissions relating to “land banking” which it defined as a supermarket purchasing land without an intention to develop it (or to develop it in a timely manner) in order to stop competitors establishing supermarkets on it.

Information provided to the Commission suggested Woolworths had interests in 110 sites intended for future supermarket use and Coles had interests in 42.

The Commission had not yet formed conclusions about whether land banking was occurring.

It said Coles and Woolworths had also acquired entire shopping centres, including those where competitors operated.

The Albanese government has indicated it will examine the visa status of protesters waving Hezbollah flags at pro-Palestine demonstrations in Sydney and Melbourne over the weekend.

Home Affairs Minister Tony Burke said on Monday the government was asking authorities in the two states to “check the visa status of anyone who comes to their attention”.

“I won’t hesitate to cancel the visas of visitors to our country who are spreading hate,” Burke said.

In public comments at the start of Monday’s cabinet meeting, Prime Minister Anthony Albanese said: “We’ve seen worrying signs over the weekend. We do not want people to bring radical ideologies and conflict here. Our multiculturalism and social cohesion cannot be taken for granted.”

Opposition spokesman James Paterson said those with Hezbollah flags who are on visas should have them cancelled and they should be deported.

“It’s a breach of the Commonwealth Criminal Code,” Paterson said. “In December last year, the parliament voted unanimously to amend the Commonwealth Criminal Code to make it an offence to display either a Nazi logo or symbol or the symbol of a listed terrorist organisation, and that includes Hezbollah.”

The Australian Federal Police late Monday said it was expecting at least six “reports of crime” from Victoria Police allegedly involving prohibited symbols and chants, that were being investigated by the AFP for potentially breaching the Counter-Terrorism legislation.

“The mere public display of a prohibited symbol on its own does not meet the threshold of a Commonwealth offence,” the AFP said.

“The Criminal Code set outs very specific elements that must be met in order to charge an individual with a prohibited symbol offence.

“The prohibited symbol must be displayed in circumstance where the conduct involves: spreading ideas based on racial superiority or hatred; inciting others to offend or intimidate a person; advocating hatred of a person; advocating inciting others to offend, intimidating or using force or violence against a person or group based upon their race, religion or nationality; or is likely to offend, insult or intimidate people because of a defining characteristic.”

Meanwhile, the government has appointed Aftab Malik, a New South Wales public servant who has worked on promoting social cohesion and countering extremism, as its special envoy to combat Islamophobia.

The announcement comes following a long search, and well after the appointment of a special envoy to combat antisemitism, Jillian Segal.

Albanese and Burke said in a statement Malik, who was born in in Britain to Pakistani parents, is “recognised as a global expert on Muslim affairs by the UN Alliance of Civilisations”.

He has served as the senior advisor to the Abu Dhabi Forum for Promoting Peace, and as a board advisor to the British Council’s “Our Shared Future” project, headquartered in Washington DC.

Albanese and Burke said the appointment was part of the government’s strategy “to ensure all Australians feel safe and included”.

Malik will engage with members of the Muslim community, experts on religious discrimination and all levels of government, in combatting Islamophobia. He is appointed for three years and will report to both Albanese and Burke.

Malik said antisemitism and Islamophobia were “not mutually exclusive – where there is one, you will most likely find the other”.

The appointment was immediately criticised by the Australian Palestine Advocacy Network (APAN).

APAN said these envoys “which single out particular experience of racism for special government investment and attention, failed to address the increasingly frequent and severe forms of racism experienced by Palestinians – not all of whom are Muslims – First Nations peoples and other marginalised communities”.

“APAN calls on the federal government to dissolve both special envoy roles and instead engage in evidence-based, systemic anti-racism efforts that support the entire Australian community in eliminating racism and bigotry.”

Water flows in mainland Australia’s most important river system, the Murray-Darling Basin, have been declining for the past 50 years. The trend has largely been blamed on water extraction, but our new research shows another factor is also at play.

We investigated why the Darling River, in the northern part of the basin, has experienced devastating periods of low flow, or no flow, since the 1990s. We found it was due to a decrease in rainfall in late autumn, caused by climate change.

The research reveals how climate change is already affecting river flows in the basin, even before water is extracted for farm irrigation and other human uses.

Less rain will fall in the Darling River catchment as climate change worsens. This fact must be central to decisions about how much water can be taken from this vital natural system.

A quick history of the Darling

The Darling River runs from the town of Bourke in northwest New South Wales, south to the Murray River in Victoria. Together, the two rivers form the Murray-Darling river system.

The Indigenous name for the Darling River is the Baaka. For at least 30,000 years the river has been an Indigenous water resource. On the river near Wilcannia, remnants of fish traps and weirs built by Indigenous people can still be found today.

The Darling River was a major transport route from the late 19th to the early 20th century.

In recent decades, the agriculture industry has extracted substantial quantities of water from the Darling’s upstream tributaries, to irrigate crops and replenish farm dams. Water has also been extracted from Menindee Lakes, downstream in the Darling, to benefit the environment and supply the regional city of Broken Hill.

A river in trouble

Natural weather variability means water levels in the Darling River have always been irregular, even before climate change began to be felt.

In recent years, however, water flows have become even more irregular. This has caused myriad environmental problems.

At Menindee Lakes, for example, fish have died en masse – incidents experts say is ultimately due to a lack of water in the river system.

Periods of heavy rain in recent years have dramatically improved water flows.

But in between those episodes, water levels and quality have declined, due to factors such as droughts, expanded water extraction, salinity and pollution from farms.

Compounding the droughts, smaller flows that once replenished the system have now greatly reduced. Our research sought to determine why.

What we found

We examined rainfall and water flows in the Darling River from 1972 until July 2024. This includes from the 1990s – a period when global warming accelerated.

We found a striking lack of short rainfall periods in April and May in the Darling River from the 1990s. The reduced rainfall led to long periods of very low, or no flow, in the river.

Since the 1990s under climate change, shifts in atmospheric circulation have generated fewer rain-producing systems. This has led to less rain in inland southeast Australia in autumn.

The river system particularly needs rainfall in the late autumn months, to replenish rivers after summer.

The periods of little rain were often followed by extreme floods. This is a problem because the rain fell on dry soils and soaked in, rather than running into the river. This reduced the amount of water available for the environment and human uses.

In addition to the fall in autumn rainfall, we found the number of extreme annual rainfall totals for all seasons has also fallen since the 1990s.

We also examined monthly river heights at Bourke, Wilcannia and Menindee. We found periods of both high and low water levels before the mid-1990s. But the low water levels at all three locations from 2000 onwards were the lowest in the period.

Ensuring water for all

Australia is the driest inhabited continent on Earth. Ensuring steady water supplies for human use has always been challenging.

Falls in Darling River water levels in recent decades have largely been attributed to water extraction for farm dams, irrigation and town use.

But as our research shows, the lack of rainfall in the river catchment – as a result of climate change – is also significant. The problem will worsen as climate change accelerates.

This creates a huge policy challenge. As others have noted, the Murray-Darling Basin Plan does not properly address climate change when determining how much water can be taken by towns and farmers.

Both the environment and people will benefit from ensuring the rivers of the basin maintain healthy flows into the future. As our research indicates, this will require decision-makers to consider and adapt to climate change.

From the creeks that wind through inner city Melbourne to the far outback in Western Australia, snake season is beginning.

Over the cooler months snakes have been in state of brumation. This is very similar to hibernation and characterised by sluggishness and inactivity. As warmer conditions return both snakes and humans become more active in the outdoors, leading to an increased likelihood of interaction. This may happen when people are hiking, dog-walking or gardening.

The risk of being bitten by a snake is exceptionally small, but knowing basic first aid could potentially save your, or another person’s, life.

When a snake bites

Snake bite envenomation (when venom enters the blood stream) is a significant issue in Australia, with 3,000 cases annually and an average of two deaths.

Snake bite should always be treated as a life-threatening emergency, and if you are bitten in rural or remote Australia, you will often receive an air medical emergency pick up to a regional or metropolitan hospital for advanced care.

The effects of snake bites vary, depending on the species of snake and first aid measures undertaken.

Australian standard first aid guidelines include:

• calling for help (dialing 000 or activating an emergency beacon)
• applying a pressure immobilisation bandage
• resting.

Why pressure is important

Snake venom is carried within the lymphatic system. This is a collection of tiny tubes throughout the body that return fluid outside of blood vessels back to the blood stream.

Muscles act as a “pump” to help the fluid move through this system. That’s why being still, or immobilisation, is vital to slow the spread of venom.

A firm pressure immobilisation bandage, applied as tight as you would for a sprained ankle, will compress these tubes and help limit the venom’s spread.

Ideally bandage the entire limb on which the bite occurred and apply a splint to help further with immobilisation. It is very important that the blood supply to the limb is not limited by this bandage.

Never attempt to capture or kill the snake for identification. This risks further bites and is not required for specialist care. The decision about when to give antivenom (if any) is based on the geographical location, symptoms, the results of blood tests and discussion with a toxicologist.

The tyranny of distance

People living in rural and remote locations may also have limited access to health care, including access to ambulance services, snake bite first aid such as bandages and splints, and to antivenom.

Availability and the prompt use of antivenom have been identified as crucial factors in the effective treatment of snake envenomation – but not studied in detail.

Over one year (as a component of a larger three-year study) we collected information on the pre-hospital care and in-flight care with the Royal Flying Doctors Service Western Operations.

During this time, 85 people from regional, rural, remote and very remote Western Australia were flown by Royal Flying Doctor Service to hospital for suspected or confirmed snake bites. Reassuringly, only five of these patients (6%) ultimately received a toxicologist’s diagnosis of envenomation.

To move or not to move?

Troublingly, 38 (45%) of the 85 snake bite victims continued to move around and be active following their suspected snake bite. This raises questions about whether people lack knowledge of first-aid guidelines, or whether this is a consequence of being isolated, with limited access to health care.

Either way, our as-yet-unpublished research highlights the vulnerability of Australia’s rural and remote people. All patients eventually received a pressure immobilisation bandage, with an average time from bite to application of 38 minutes. Three quarters of the patients made their way to health-care site by foot, or private car, arriving on average 65 minutes after the bite.

What needs to change?

Our results indicate rural and remote Australians need innovative health-care solutions beyond the metropolitan guidelines, particularly when outside ambulance service areas.

Basic snake bite first aid education needs to be not only reiterated but also a pragmatic approach is required in these geographically isolated locations. This would involve being vigilant, staying safe and, when isolated, always carrying emergency technology to call for help.

More than 1.1 million Australians are estimated to be living with an eating disorder. Around one-third of these people are neurodivergent.

So why are neurodivergent people, such as autistic people and those with ADHD, more likely to experience eating disorders than the broader population? And how does this impact their treatment?

First, what is neurodivergence?

Neurodivergence, or the state of being neurodivergent, is a term for people whose cognitive functioning differs from what society considers “typical”. Many conditions broadly fall under neurodivergence, including (but not limited to):

• autism
• attention-deficit/hyperactivity disorder (ADHD)
• dyslexia
• Tourette’s syndrome.

Our understanding of neurodivergence has come a long way. Neurodivergence used to be considered a linear “spectrum” ranging from less to more neurodivergent.

We now know every neurodivergent person will have a unique experience across a range of dimensions. This includes sensory processing, motor abilities and executive functioning (working memory, cognitive flexibility and inhibition).

Conceptualising these differences ends up looking more like a colour wheel.

What are eating disorders?

Eating disorders are complex and potentially life-threatening mental health conditions. They cause persistent and significant disturbances in thoughts, feelings and behaviours related to body weight, food and/or eating.

Many factors are likely to contribute to the development of an eating disorder. But research shows neurodivergent people are disproportionately affected.

One review found around 22.9% of autistic people had an eating disorder, compared with 2% in the general population. In another review, people with ADHD were four times more likely to be diagnosed with an eating disorder than people without ADHD.

Why are eating disorders more common among neurodivergent people?

Science has not pinpointed an exact reason why eating disorders are more common among neurodivergent people. But here’s what we know so far.

Neurodivergent people are more likely to experience feeding difficulties, sensory sensitivities and disordered eating.

A United States study assessing the eating behaviour of neurodivergent children found around 70% of autistic children displayed “atypical” eating behaviours. This includes food selectivity and a hypersensitivity to food textures. It compares with 4.8% of neurotypical children.

Similarly, autistic children may choose or reject foods based on texture more than other children. They may prefer foods with a consistent texture, bland taste and neutral colour (for example, chicken nuggets, plain pasta and rice).

Selective eating (having limited accepted foods and food aversions) has been associated with avoidant/restrictive food intake disorder (ARFID). This is an eating disorder characterised by avoidance and aversion to food and eating that is not related to body image. ARFID is commonly associated with autism, with one study estimating 21% of autistic people will experience it in their lifetime.

Other neurodivergent traits, such as perfectionism and a preference for routine, have been associated with disordered eating and eating disorders.

Research on adolescent girls found those with anorexia nervosa are more likely to exhibit neurodivergent (in this case, autistic) traits and behaviours. These include developing rules, resistance to change and a hyperfocus on body weight. These features are commonly seen in anorexia nervosa, an eating disorder characterised by restricted food intake, an intense fear of weight gain and body image disturbances.

Meanwhile, impulsivity symptoms in ADHD have been associated with binge eating disorder. This can involve recurrent episodes of eating large amounts of food in a short period of time. Impulsivity may also be linked to bulimia nervosa, characterised by compensatory behaviours to prevent weight gain after binge eating (such as exessive exercise).

Some studies indicate a link between ADHD, alexithymia (difficulty experiencing, identifying and expressing emotions) and overeating behaviours such as emotional eating.

Finally, neurodivergent people are more likely to identify as part of the LGBTQIA+ community, experience trauma and also have a mental health condition. Each of these considerations increases the likelihood someone will experience an eating disorder.

How does this affect treatment?

Despite the overlap between eating disorders and neurodivergence, current treatment approaches don’t meet the diverse needs of those affected.

Eating disorder treatment often has moderate success at best. For neurodivergent people, the outcomes are worse than for their neurotypical counterparts.

Cognitive behavioural therapy (CBT), a broad range of treatments based on the interaction between thoughts, feelings and behaviours, is less beneficial for neurodivergent people. Yet this is often part of treatment for eating disorders. Autistic women have suggested CBT is less accessible due to its blanket approach and the assumption they have the skills needed to benefit.

There have been calls from organisations such as the National Eating Disorders Collaboration and lived experience advocates to improve access to neurodiversity-affirming care models for neurodivergent people affected by eating disorders.

Such care recognised and safely accommodates the multiple ways neurodivergence is related to feeding and eating behaviour.

Research suggests eating disorder treatment can be successfully adapted for neurodivergent people based on the following principles:

1. equal partnership. Including neurodivergent people as equal partners in their care and as decision-makers, and elevating their own experiences

2. embracing and celebrating differences. Neurodivergent traits should not be considered a deficit, or something to be “treated” or “fixed”. Rather, neurodivergent traits should be celebrated to nourish a positive sense of identity

3. accommodations. Neurodivergent traits and preferences are respected and accommodated. As an example, this might include reducing sensory inputs (the smell, sounds and lights) in a dining area, or a meal plan that is predictable and considers a person’s sensory sensitivities.

Treatment for eating disorders should also be gender-affirming (interventions that support and affirm someone’s gender identity) and trauma-informed.

Imagine scrolling through social media or playing an online game, only to be interrupted by insulting and harassing comments. What if an artificial intelligence (AI) tool stepped in to remove the abuse before you even saw it?

This isn’t science fiction. Commercial AI tools like ToxMod and Bodyguard.ai are already used to monitor interactions in real time across social media and gaming platforms. They can detect and respond to toxic behaviour.

The idea of an all-seeing AI monitoring our every move might sound Orwellian, but these tools could be key to making the internet a safer place.

However, for AI moderation to succeed, it needs to prioritise values like privacy, transparency, explainability and fairness. So can we ensure AI can be trusted to make our online spaces better? Our two recent research projects into AI-driven moderation show this can be done – with more work ahead of us.

Negativity thrives online

Online toxicity is a growing problem. Nearly half of young Australians have experienced some form of negative online interaction, with almost one in five experiencing cyberbullying.

Whether it’s a single offensive comment or a sustained slew of harassment, such harmful interactions are part of daily life for many internet users.

The severity of online toxicity is one reason the Australian government has proposed banning social media for children under 14.

But this approach fails to fully address a core underlying problem: the design of online platforms and moderation tools. We need to rethink how online platforms are designed to minimise harmful interactions for all users, not just children.

Unfortunately, many tech giants with power over our online activities have been slow to take on more responsibility, leaving significant gaps in moderation and safety measures.

This is where proactive AI moderation offers the chance to create safer, more respectful online spaces. But can AI truly deliver on this promise? Here’s what we found.

‘Havoc’ in online multiplayer games

In our Games and Artificial Intelligence Moderation (GAIM) Project, we set out to understand the ethical opportunities and pitfalls of AI-driven moderation in online multiplayer games. We conducted 26 in-depth interviews with players and industry professionals to find out how they use and think about AI in these spaces.

Interviewees saw AI as a necessary tool to make games safer and combat the “havoc” caused by toxicity. With millions of players, human moderators can’t catch everything. But an untiring and proactive AI can pick up what humans miss, helping reduce the stress and burnout associated with moderating toxic messages.

But many players also expressed confusion about the use of AI moderation. They didn’t understand why they received account suspensions, bans and other punishments, and were often left frustrated that their own reports of toxic behaviour seemed to be lost to the void, unanswered.

Participants were especially worried about privacy in situations where AI is used to moderate voice chat in games. One player exclaimed: “my god, is that even legal?” It is – and it’s already happening in popular online games such as Call of Duty.

Our study revealed there’s tremendous positive potential for AI moderation. However, games and social media companies will need to do a lot more work to make these systems transparent, empowering and trustworthy.

Right now, AI moderation is seen to operate much like a police officer in an opaque justice system. What if AI instead took the form of a teacher, guardian, or upstander – educating, empowering or supporting users?

Enter AI Ally

This is where our second project AI Ally comes in, an initiative funded by the eSafety Commissioner. In response to high rates of tech-based gendered violence in Australia, we are co-designing an AI tool to support girls, women and gender-diverse individuals in navigating safer online spaces.

We surveyed 230 people from these groups, and found that 44% of our respondents “often” or “always” experienced gendered harassment on at least one social media platform. It happened most frequently in response to everyday online activities like posting photos of themselves, particularly in the form of sexist comments.

Interestingly, our respondents reported that documenting instances of online abuse was especially useful when they wanted to support other targets of harassment, such as by gathering screenshots of abusive comments. But only a few of those surveyed did this in practice. Understandably, many also feared for their own safety should they intervene by defending someone or even speaking up in a public comment thread.

These are worrying findings. In response, we are designing our AI tool as an optional dashboard that detects and documents toxic comments. To help guide us in the design process, we have created a set of “personas” that capture some of our target users, inspired by our survey respondents.

We allow users to make their own decisions about whether to filter, flag, block or report harassment in efficient ways that align with their own preferences and personal safety.

In this way, we hope to use AI to offer young people easy-to-access support in managing online safety while offering autonomy and a sense of empowerment.

We can all play a role

AI Ally shows we can use AI to help make online spaces safer without having to sacrifice values like transparency and user control. But there is much more to be done.

Other, similar initiatives include Harassment Manager, which was designed to identify and document abuse on Twitter (now X), and HeartMob, a community where targets of online harassment can seek support.

Until ethical AI practices are more widely adopted, users must stay informed. Before joining a platform, check if they are transparent about their policies and offer user control over moderation settings.

The internet connects us to resources, work, play and community. Everyone has the right to access these benefits without harassment and abuse. It’s up to all of us to be proactive and advocate for smarter, more ethical technology that protects our values and our digital spaces.

The US presidential election will be held on November 5. In analyst Nate Silver’s aggregate of national polls, Democrat Kamala Harris leads Republican Donald Trump by 49.3–46.0 – a slight widening of the competition since last Monday, when Harris led Trump by 49.2–46.2.

President Joe Biden’s final position before his withdrawal as Democratic candidate on July 21 was a national poll deficit against Trump of 45.2–41.2.

There will be a debate on Tuesday evening US time between the vice-presidential candidates, Democrat Tim Walz and Republican JD Vance. Vice-presidential debates in previous elections have not had a significant influence on the contest.

The US president isn’t elected by the national popular vote, but by the Electoral College, in which each state receives electoral votes equal to its federal House seats (population based) and senators (always two). Almost all states award their electoral votes as winner-takes-all, and it takes 270 electoral votes to win (out of 538 total).

The Electoral College is biased to Trump relative to the national popular vote, with Harris needing at least a two-point popular vote win in Silver’s model to be the Electoral College favourite.

In Silver’s polling averages, Harris leads Trump by one to two points in Pennsylvania (19 electoral votes), Michigan (15), Wisconsin (ten) and Nevada (six). If Harris wins all these states, she is likely to win the Electoral College by at least a 276–262 margin. Trump is ahead by less than a point in North Carolina (16 electoral votes) and Georgia (16), and if Harris wins both, she wins by 308–230.

In Silver’s model, Harris has a 56% chance to win the Electoral College, up from 54% last Monday but down from her peak of 58% two days ago. Earlier this month, there were large differences in win probability between Silver’s model and the FiveThirtyEight model, which was more favourable to Harris. But these models have nearly converged, with FiveThirtyEight now giving Harris a 59% win probability.

There are still more than five weeks until election day, so polls could change in either Trump’s or Harris’ favour by then. Harris’ one to two point leads in the key states are tenuous, and this explains why Trump is still rated a good chance to win.

Silver wrote on September 1 that polls in 2020 and 2016 were biased against Trump, but polls in 2012 were biased against Barack Obama. In the last two midterm elections (2022 and 2018), polls have been good. It’s plausible there will be a polling error this year, but which candidate such an error would favour can’t be predicted.

On Sunday, Silver said if there was a systematic error of three or four points in the polls in either Trump’s or Harris’ favour, that candidate would sweep all the swing states and easily win the Electoral College. There are other scenarios in which one candidate underperforms the polls with some demographics but overperforms with other demographics.

I wrote about the US election for The Poll Bludger last Thursday, and also covered bleak polls and byelection results in Canada for the governing centre-left Liberals ahead of an election due by October 2025, a dreadful poll for UK Labour Prime Minister Keir Starmer, the new French prime minister, a German state election and a socialist win in Sri Lanka’s presidential election.

Upwardly revised economic data

Last Thursday, a revised estimate of June quarter US GDP was released. There was a large upward revision in real disposable personal income compared to the previously reported figures. This has resulted in the personal savings rate being revised up to 4.9% in July from the previously reported 2.9%, and it was 4.8% in August.

With these upward revisions, Silver’s economic index that averages six indicators is now at +0.25, up from +0.09. As the incumbent party’s candidate, a better economy than was previously believed should help Harris.

Coalition gains narrow lead in Essential

In Australia, a national Essential poll, conducted on September 18–22 from a sample of 1,117 people, gave the Coalition a 48–47 lead (including undecided voters) after a 48–48 tie in early September. It’s the Coalition’s first lead in the Essential poll since mid-July.

Primary votes were 35% Coalition (steady), 29% Labor (down one), 12% Greens (down one), 8% One Nation (steady), 2% UAP (up one), 9% for all Others (up one) and 5% undecided (steady).

Anthony Albanese’s net approval was up five points since August to –5, with 47% disapproving and 42% approving. Peter Dutton’s net approval was down one to net zero.

On social media regulations, 48% thought them too weak, 43% about right and 8% too tough. By 67–17, voters supported imposing an age limit for children to access social media (68–15 in July). By 71–12, voters supported making doxing (the public release of personally identifiable data) a criminal offence (62–19 in February).

By 49–18, voters supported Labor’s Help to Buy scheme, and by 57–13 they supported the build-to-rent scheme. The questions give detail that few voters would know.

Voters were told the Liberals and Greens had combined to delay Labor’s housing policies in the senate. By 48–22, voters thought the Liberals and Greens should pass the policies and argue for their own policies at the next election, rather than block Labor’s policies. Greens voters supported passing by 55–21.

Labor keeps narrow lead in Morgan

A national Morgan poll, conducted September 16–22 from a sample of 1,662 people, gave Labor a 50.5–49.5 lead, unchanged from the September 9–15 Morgan poll.

Primary votes were 37.5% Coalition (steady), 32% Labor (up 1.5), 12.5% Greens (steady), 5% One Nation (down 0.5), 9.5% independents (down 0.5) and 3.5% others (down 0.5).

The headline figure is based on respondent preferences. By 2022 election preference flows, Labor led by an unchanged 52–48.

The onslaught in the Middle East has brought to the world’s attention once again the “crime of crimes”, genocide.

Both the the International Court of Justice and International Criminal Court (ICC) have brought allegations of genocide against Israel as a state and Israeli and Hamas leaders as individuals.

The Australian government’s response to the Gaza crisis has included temporarily freezing of A$6 million of funding to the United Nations Relief and Works Agency for Palestine. Though funding has been flowing again since March, Prime Minister Anthony Albanese has been referred to the ICC by a law firm for being “an accessory to genocide”.

Against this backdrop, Australia’s own genocide legislation is under parliamentary scrutiny. A bill tabled by independent Senator Lidia Thorpe (for whom I work as a casual legal researcher) seeks to change the way Australia deals with genocide.

So what do our current laws say and what’s the case for changing them?

What do our laws say?

Australia ratified the Genocide Convention in 1949.

Yet it was not until 2002, once the ICC was established, that the Commonwealth Criminal Code was amended to create a new division of atrocity crimes.

Through this legislation, Australia may prosecute any person accused of a Rome Statute crime (such as genocide) under Australian law.

At the moment, written consent from the attorney-general is required before legal proceedings about genocide and other atrocity crimes can commence. This is called the “attorney-general’s fiat”.

Further, the attorney-general’s decision is final. It “must not be challenged, appealed against, reviewed, quashed or called into question”.

Thorpe’s bill seeks to overturn these two measures.

The explanatory memorandum in the 2002 amendment did not say why the attorney-general’s consent was necessary.

Consent from an attorney-general (or similar position) is not an international requirement.

Australia is only one of a handful of other countries (including the United Kingdom, New Zealand and Canada) where the fiat also exists.

Why is it a problem?

The Australian government has justified the rule on the basis that prosecutions for atrocity crimes against individuals could affect Australia’s international relations and national security.

However, submissions from legal experts and community groups to a senate inquiry looking at the issue point out flaws.

They say this rule prevents access to justice for victims and survivors of atrocity crimes. It can also create the potential for government bias.

Submissions also say the lack of explanation or appeal process ignores fundamental principles of jurisprudence.

Has the rule been used?

The attorney-general’s fiat has been used in a limited number of cases.

In 2009, Palestinian rights groups Australians for Palestine issued a request for consent for the prosecution of former Israeli prime minister Ehud Olmert, who was visiting at the time.

The Australian Centre for International Justice states in its submission how then-attorney-general Robert McClellend denied the request. He cited matters of international state sovereignty and the difficulties of pursuing such a case in an overseas jurisdiction.

Then, in 2011, Arunchalam Jegastheeswaran, an Australian citizen of Tamil
background, sought the attorney-general’s consent for the prosecution of then Sri Lankan President, Mahinda Rajapaksa, who was due to visit Australia.

McClellend again denied the request, saying Rajapaska was protected under “head of state immunity”. This concept is controversial in international law, given it’s often heads of state who commit atrocity crimes.

Head of state protection was also offered to former Myanmar (Burma) leader Aung San Suu Kyi, who was in government when the 2017 genocide against the Rohingya was committed.

With Suu Kyi due to be in Australia for an ASEAN conference in 2018, the Australian Rohingya community sought a prosecution. It was denied by then attorney-general Christian Porter.

And in 2019, retired Sri Lankan General Jagath Jayasuriya visited Australia. Despite concerted efforts to raise evidence to prosecute Jayasuriya of war crimes, delays with the Australian Federal Police meant the case never reached the point of attorney-general consent.

First Nations plaintiffs such as Paul Coe and Robert Thorpe have also sought to bring cases of genocide before the domestic courts, with no success.

What would changing the laws mean?

As it’s unlikely an attorney-general would consent to prosecutions against its own government, submissions to the inquiry argue the rule creates a direct conflict of interest.

For First Nations people seeking justice for crimes of “ongoing genocide” perpetuated by the Commonwealth, any government is hardly going to rule in their favour.

Some Indigenous community groups argue the high rates of First Nations children in protection, deaths in custody, hyper-incarceration and cultural, land and environmental damage amount to genocide crimes.

Submissions to the inquiry recommend instead of requiring the consent of the attorney-general, claims of genocide should be directed to the Commonwealth Director of Public Prosecutions. This would ensure greater independence from government.

The director has a mandate for this sort of work. It already investigates similar crimes such as people smuggling, human trafficking, slavery and child exploitation.

Internationally, the implications of this bill, if passed, will be consequential. The Australian Centre for International Justice estimates up to 1,000 Australian citizens have returned to Israel to fight as part of the Israel Defense Forces. Israel has been accused of serious atrocity crimes in Gaza.

Should any of those citizens return, there could be attempts to mount a case. The government would then have to consider Australia’s political and economic ties with Israel.

Whether the bill is passed will depend on parliament. But the situation highlights a paradox: the state itself will be deciding whether to remove its own inbuilt protections against charges of genocide.

The development of “superhuman” strength and power has long been admired in many cultures across the world.

This may reflect the importance of these physical fitness characteristics in many facets of our lives from pre-history to today: hunting and gathering, the construction of large buildings and monuments, war, and more recently, sport.

Potentially, the current peak of human strength and power is demonstrated in the sport of strongman.

What is strongman?

Strongman is becoming more common, with competitions now available at regional, national and international levels for men and women of different ages and sizes.

Read more:
Strongman used to be seen as a super-human novelty sport. Now more women and novices are turning to it

Strongman training and competitions typically involve a host of traditional barbell-based exercises including squats, deadlifts and presses but also specific strongman events.

The specific strongman events – such as the vehicle pull, farmer’s walk, sandbag/keg toss or stones lift – often require competitors to move a range of awkward, heavy implements either higher, faster or with more repetitions in a given time period than their competitors.

Researching one of the greats

Strongman has enjoyed substantial growth and development since the introduction of the World’s Strongest Man competition in the late 1970s.

However, from a scientific perspective, there are few published studies focusing on athletes at the elite level.

In particular, very little is currently known about the overall amount of muscle mass these athletes possess, how their mass is distributed across individual muscles and to what extent their tendon characteristics differ to people who are not training.

However a recent study sought to shed some light on these extreme athletes. It examined the muscle and tendon morphology (structure) of one of the world’s strongest ever men – England’s Eddie Hall.

Measuring an exceptionally strong person such as Hall – who produced a 500kg world record deadlift and won the “World’s Strongest Man” competition in 2017 – provided the opportunity to understand what specific muscle and tendon characteristics may have contributed to his incredible strength.

What can we learn from a single case study?

A limited number of athletes reach the truly elite level of strongman and even fewer set world records or win premier events.

Because it’s so difficult to recruit even a small group of such rare athletes, conducting a case study with one elite strongman provided a unique opportunity to understand more about his muscle and tendon characteristics.

Case studies have many limitations, including an inability to determine cause and effect or generalise findings to other individuals from the same group.

However, the study of Hall was insightful, as his muscle and tendon results could be compared directly with various groups from the authors’ earlier published research.

These groups included untrained people, people who have regularly resistance trained for several years, and competitive track sprinters.

The inclusion of these comparative populations allowed meaningful interpretation of what makes Hall’s muscle and tendon characteristics so special.

What they found

Hall’s lower body muscle size was almost twice that of an untrained group of healthy active young men.

And the manner in which his muscle mass was distributed across his lower body exhibited a very specific pattern.

Three long thin muscles, referred to as “guy ropes”, were particularly large (some 2.5 to three times bigger) compared to untrained people.

The guy rope muscles connect to the shin bone via a shared tendon and provide stability to the thigh and hips by fanning out and attaching to the pelvis at diverse locations.

Highly developed guy rope muscles would be expected to offer enhanced stability with heavy lifting, carrying and pulling.

Hall’s thigh (quadriceps) muscle structure was more than twice that of untrained people, yet the tendon at the knee that is connected to this muscle group was only 30% larger than an untrained population.

This finding indicates muscle and tendon growth, within this case of extreme quadriceps muscle development, do not occur to the same extent.

What do the results mean?

The obvious implication is, the larger the relevant muscles, the greater the potential for strength and power.

However, sports like strongman and even everyday activities like climbing stairs, carrying groceries and lifting objects off the ground require the coordinated activity of many stabilising muscles as well as major propulsive muscles such as the quadriceps.

While Hall’s quadriceps were substantially bigger than untrained people, the largest relative differences occurred in the calves and the long thin “guy rope” muscles that help stabilise the hip and knee.

These results pose a question about whether additional or more specific training for these smaller muscles may further enhance strength and power.

This could benefit strongman athletes as well as everyday people.

Also, the relatively small differences in tendon size between Hall and untrained populations suggests tendons do not grow to the same extent as muscles do.

As muscular forces are transmitted through tendons to the bones, the substantially greater growth of muscle than tendon may mean athletes such as Hall have a greater relative risk of tendon than muscle injury.

This view is somewhat consistent with the high proportion of tendinitis and strains reported in strength sport athletes, including strongman and weightlifters.

Humans are increasingly engaging with wearable technology as it becomes more adaptable and interactive. One of the most intimate ways gaining acceptance is through augmented reality (AR) glasses.

Last week, Meta debuted a prototype of the most recent version of their AR glasses – Orion. They look like reading glasses and use holographic projection to allow users to see graphics projected through transparent lenses into their field of view.

Meta chief Mark Zuckerberg called Orion “the most advanced glasses the world has ever seen”. He said they offer a “glimpse of the future” in which smart glasses will replace smartphones as the main mode of communication.

But is this true or just corporate hype? And will AR glasses actually benefit us in new ways?

Old technology, made new

The technology used to develop Orion glasses is not new.

In the 1960s, computer scientist Ivan Sutherland introduced the first augmented reality head-mounted display. Two decades later, Canadian engineer and inventor Stephen Mann developed the first glasses-like prototype.

Throughout the 1990s, researchers and technology companies developed the capability of this technology through head-worn displays and wearable computing devices. Like many technological developments, these were often initially focused on military and industry applications.

In 2013, after smartphone technology emerged, Google entered the AR glasses market. But consumers were disinterested, citing concerns about privacy, high cost, limited functionality and a lack of a clear purpose.

This did not discourage other companies – such as Microsoft, Apple and Meta – from developing similar technologies.

Looking inside

Meta cites a range of reasons for why Orion are the world’s most advanced glasses, such as their miniaturised technology with large fields of view and holographic displays. It said these displays provide:

compelling AR experiences, creating new human-computer interaction paradigms […] one of the most difficult challenges our industry has ever faced.

Orion also has an inbuilt smart assistant (Meta AI) to help with tasks through voice commands, eye and hand tracking, and a wristband for swiping, clicking and scrolling.

With these features, it is not difficult to agree that AR glasses are becoming more user-friendly for mass consumption. But gaining widespread consumer acceptance will be challenging.

A set of challenges

Meta will have to address four types of challenges:

1. ease of wearing, using and integrating AR glasses with other glasses
2. physiological aspects such as the heat the glasses generate, comfort and potential vertigo
3. operational factors such as battery life, data security and display quality
4. psychological factors such as social acceptance, trust in privacy and accessibility.

These factors are not unlike what we saw in the 2000s when smartphones gained acceptance. Just like then, there are early adopters who will see more benefits than risks in adopting AR glasses, creating a niche market that will gradually expand.

Similar to what Apple did with the iPhone, Meta will have to build a digital platform and ecosystem around Orion.

This will allow for broader applications in education (for example, virtual classrooms), remote work and enhanced collaboration tools. Already, Orion’s holographic display allows users to overlay digital content and the real world, and because it is hands-free, communication will be more natural.

Creative destruction

Smart glasses are already being used in many industrial settings, such as logistics and healthcare. Meta plans to launch Orion for the general public in 2027.

By that time, AI will have likely advanced to the point where virtual assistants will be able to see what we see and the physical, virtual and artificial will co-exist. At this point, it is easy to see that the need for bulky smartphones may diminish and that through creative destruction, one industry may replace another.

This is supported by research indicating the virtual and augmented reality headset industry will be worth US$370 billion by 2034.

The remaining question is whether this will actually benefit us.

There is already much debate about the effect of smartphone technology on productivity and wellbeing. Some argue that it has benefited us, mainly through increased connectivity, access to information, and productivity applications.

But others say it has just created more work, distractions and mental fatigue.

If Meta has its way, AR glasses will solve this by enhancing productivity. Consulting firm Deloitte agrees, saying the technology will provide hands-free access to data, faster communication and collaboration through data-sharing.

It also claims smart glasses will reduce human errors, enable data visualisation, and monitor the wearer’s health and wellbeing. This will ensure a quality experience, social acceptance, and seamless integration with physical processes.

But whether or not that all comes true will depend on how well companies such as Meta address the many challenges associated with AR glasses.

As summer approaches, the threat of bushfires looms. Earlier this month, an out-of-control blaze in Sydney’s northern beaches burnt more than 100 hectares of bushland, threatening nearby homes.

Climate change is making bushfires larger, hotter and faster. Previously unthinkable catastrophes, such as the “Black Summer” megafires in Australia in 2019/2020 and the ones that ravaged Maui, Hawaii, in August 2023, are becoming more common.

Firefighters put their lives on the line to battle these fires. Yet many are not meaningfully and comprehensively prepared to respond to erratic and extreme conflagrations. This increases their chances of being injured, or worse. It may also hinder their ability to make the best decisions.

To help address this, the University of New South Wales’ iCinema Research Centre has created iFire. This cutting-edge training system allows firefighters and emergency responders to virtually teleport into a burning landscape and train for the real thing. It could revolutionise the way we prepare for other natural disasters as well.

Megafires are becoming more common

The rate of extreme fire events has doubled over the past decade. These fires can combine with the atmosphere to produce their own weather systems, generating multiple fire fronts. As the planet continues to warm, this situation will only get worse.

Much current research is focused on understanding these worsening fire threats. This is vital. But data and charts don’t meaningfully prepare firefighters for how to respond to such extreme, unanticipated fires.

“Experiential preparedness” is the missing element.

It helps firefighters prepare by virtually experiencing and rehearsing how to respond to real and future extreme fires through immersive scenarios. This can be done in a large-scale, three-dimensional cinema or on a smart tablet or phone.

Simulating the fireground

The iFire collaboration builds on iCinema’s award-winning iCasts immersive training system for mine workers.

Since it was developed in 2008, iCasts has exposed and trained thousands of miners and planners in simulations of known threats before they go underground. This has resulted in a dramatic reduction in serious injuries at Australian mine sites and many lives saved.

iFire takes a similar approach. It uses a combination of mathematical modelling of actual fires provided by CSIRO’s Data61 research institute, advanced visualisation and artificial intelligence (AI) tools to recreate immersive simulations of three real case studies: a pine plantation fire, a grass fire and the 2020 Bridger-Foothills fire in the United States.

The system puts fire crews in the centre of these simulated firegrounds using immersive cinematic scenarios. The crews feel as though they are physically present. They can experience the fire from any point of view – aerial or on the ground – at any point in time, and interactively engage with it.

Importantly, the scenarios are not static reproductions of past events. Fire crews and incident commanders can adjust variables to experience the influence of changes in conditions. For example, they can change the air temperature or wind direction and see how this affects the dynamic behaviour of the fire in real time.

This allows them to better perceive risks and practise making key decisions in preparation for when they are on the actual firegrounds and under enormous pressure to act fast.

A more advanced system

iFire is already in the hands of those who need it. It has recently been installed at the Fire and Rescue NSW Emergency Services Academy in Sydney using a 130‑degree, three-dimensional, cinematic theatre.

The UNSW iCinema Centre and Fire and Rescue NSW will use iFire to develop training modules for frontline response. These modules will provide simulations where fire crews practise how to be situationally aware in the face of an unpredictable fire situation. They learn how to make the best decisions in managing the unfolding fire.

But the iFire team is working towards building a more advanced AI system that learns the underlying and unforeseen patterns of fire behaviour to create more precise and detailed simulations of these unpredictable fires.

This will enable incident commanders and firefighters to engage with unanticipated fireground threats and better prepare to protect people and property under threat from flames.

The longer-term goal is that the iFire system will ultimately enable firefighters on a tablet or any other smart screen device in any location to experience the look and feel of a possible future fire scenario in real time. This won’t be as immersive, but it will be effective for use in the field when managing a fire and will improve tactical and strategic responses.

Although iFire has been specially designed for firefighters, the technology behind it can be tweaked for many purposes. For example, it can be used to help better train and prepare emergency service workers for other natural disasters such as floods and earthquakes.

The head of the World Health Organization (WHO), Tedros Adhanom Ghebreyesus, has warned attacks on health-care workers, patients and facilities “must not become the norm”.

Yet reports from wars across the world frequently show hospitals being bombed and health workers being attacked.

The increased use of explosive weapons in densely populated areas makes the problem worse as they cause widespread harm to civilians and critical infrastructure, including health facilities. Whether these attacks are targeted or seen as “collateral damage”, there is growing concern they are becoming an accepted part of armed conflict – although they violate protections granted under international law.

But are these attacks on health care truly increasing, or are we just getting better at documenting them? More importantly, is the world beginning to see them as normal?

What does the data show?

Collecting accurate data in war zones is challenging. Many attacks on health care go unreported due to fear of reprisals or the dangers involved in gathering information. In some cases, releasing data can be sensitive, as conflicting parties may use it to sway public opinion or escalate tensions.

Despite these challenges, organisations have been tracking attacks on health care for years, including the WHO, the Safeguarding Health in Conflict Coalition (SHCC) and the International Committee of the Red Cross. Their reports show an increase in both the frequency and systematic targeting of health care in certain regions.

The latest SHCC report shows last year was the deadliest for health-care workers since reporting began a decade ago. In 2023, 480 health-care workers were killed during armed conflict – nearly double the previous year.

Between January and September 2024, the WHO has confirmed almost 700 attacks against healthcare facilities and staff in Ukraine and the Occupied Palestinian Territory alone. This has led to more than 500 injuries and nearly 200 deaths among patients and health workers.

In Sudan and Myanmar, hospitals and clinics continue to be targeted, leaving millions without access to basic care.

This violence can lead to near collapse of health-care systems. For example, by January 2024, 84% of health facilities in Gaza had been damaged or destroyed. This leaves people without essential care, worsens chronic conditions and allows diseases to spread unchecked.

The laws that protect health care

The Geneva Conventions of 1949 and their Additional Protocols form the backbone of International Humanitarian Law, protecting health workers, hospitals and patients during armed conflict. These laws were established after the second world war to ensure that, even in times of war, people can access medical care without fear of attack. Any deliberate targeting of medical services is a violation of international law and, in some cases, a war crime.

Today, every recognised state in the world has committed to complying with these laws. In 2016, the United Nations Security Council also adopted a resolution which condemns attacks on health care and calls for stronger action to ensure compliance.

Yet attacks on health care continue. Some of the most serious examples have occurred in recent armed conflicts, where hospitals and clinics have been directly targeted, often without consequences for the attackers. Earlier this year, Ukraine asked the International Criminal Court to investigate attacks against a children’s hospital in Kyiv.

The persistence of these attacks raises concerns about whether the issue is weak enforcement of the laws or whether the laws themselves need updating for modern warfare.

Some legal and medical experts argue the laws aren’t strong enough, especially with the rise of non-state armed groups such as militias. Others believe the laws are adequate but are not properly enforced.

There are growing calls from humanitarian and human rights organisations for stronger accountability, including the involvement of the International Criminal Court and national courts. Others propose a broader, more systematic approach that treats attacks on health care as a public health issue, not just a legal one.

Are attacks on health care becoming normalised?

One of the most concerning aspects of this trend is the potential normalisation of such attacks, meaning people might begin to see them as an inevitable part of war.

When hospitals are bombed or ambulances are destroyed without any punishment for the perpetrators, it sends the message health-care workers and patients are acceptable targets. This creates an environment where entire populations may feel there is no safe place to seek care when they need it the most.

Modern conflicts, involving non-state armed groups such as militias – as we’ve seen in Haiti and the Central African Republic – contribute significantly to this issue. These groups often do not adhere to international law.

However, even governments have been accused of attacking health-care facilities despite being parties to the Geneva conventions, including attacks on hospitals by Israel in Gaza, Saudi Arabia in Yemen and the United States in Afghanistan.

When these incidents are not met with strong consequences, it sets a dangerous precedent.

Immediate and long-term impacts

The immediate impact of these attacks is clear and devastating: people injured in conflict or suffering from illnesses can’t get the care they need. Health workers, who are often first responders, are directly targeted, reducing the availability of essential care.

The destruction of hospitals also disrupts routine services such as childbirth and vaccinations, leading to preventable deaths and increasing the risk of disease outbreaks. Outbreaks of mpox in the Democratic Republic of Congo and polio in Gaza have worsened because health workers can’t safely reach affected areas, and necessary supplies have been destroyed.

In the longer term, these attacks gravely affect individuals with chronic conditions such as diabetes, cancer or heart disease, which become life-threatening without treatment. Additionally, people are more likely to leave places without health-care services, which contributes to displacement.

Finally, such attacks erode trust in hospitals and clinics, causing fear around seeking medical help. Over time, this can discourage people from getting care, creating ripple effects that harm entire communities and set back global health progress.

In October 2023, a Victorian woman, Elodie Aldridge, was driving home from a midwife appointment when her car was hit by a four-wheel drive. Aldridge was 34 weeks pregnant with her son, Remi. She suffered significant injuries including a broken wrist, hip and pelvis. Her son Remi died in utero.

Under current laws in most states and territories, the life of an unborn child is legally indistinguishable from that of the mother. In Victoria, the only criminal charge available for such an offence is “serious injury to the mother”.

If this crash had occurred 50 minutes north in New South Wales, Remi would have been recognised as a legal person and there would have been a separate criminal charge for his death.

Attempts to change these laws in Victoria were recently rejected by parliament. Here’s why these laws should be changed across the country.

When are you legally a person?

Under Australian law, a life is recognised at the point when there is independence from the mother. This means the child becomes a legal person when the child can take its first independent breath, otherwise known as the “born alive rule”. Therefore, unless the child can take an independent breath, the child is not recognised as a legal person and therefore cannot be deemed a victim of the crime of murder or manslaughter.

This legal position is reflected in most jurisdictions in Australia. Victoria, the ACT, the Northern Territory, South Australia, Tasmania and Western Australia do not recognise the life of an unborn child as being separate from that of its pregnant mother.

As a result, any harm done to an unborn child in any of the above jurisdictions could only result in the charge of causing serious harm to the mother.

But it’s a different situation under administrative law. The parents can legally be granted a birth and death certificate for the child. So while there are records of a life created and lost, the criminal law doesn’t see the unborn child as a person.

Legislators and legal scholars in these jurisdictions appear reluctant to recognise the life of the unborn child in utero.

There are fears that doing so will negatively impact reproductive rights or could result in liability for a pregnant mother.

Legal and medical professionals have argued that such laws could have unintended consequences (particularly in jurisdictions where abortions are not legalised) by creating a tension between the rights of the woman to autonomy and self-determination and the rights of the unborn child.

This, in turn, could lead to further marginalisation of vulnerable and disadvantaged women, as has been seen internationally.

While the philosophical issues are unavoidable, the recognition of the legal personhood of an unborn child in particular circumstances need not be in conflict with existing women’s rights and reproductive laws.

The proposed law in Victoria, for example, should only be applied in narrow circumstances: involving the criminal (unlawful) intervention by a third party (not the mother) that results in the death of an unborn child where the child was above 20 weeks gestational age or more than 400 grams in weight.

Exceptions to the rule

There are some states that have made changes.

In 2021, some 12 years after the laws were first introduced to parliament, NSW passed laws that imposed tougher penalties for crimes that result in the loss of an unborn child.

“Zoe’s law” was proposed after Brodie Donegan, then 32 weeks pregnant with Zoe, was hit by a drunk driver on Christmas Day in 2009. The then Attorney-General Mark Speakman said:

these laws give recognition to the unborn children that are lost due to third party criminal acts.

Two offences were subsequently added the NSW Crimes Act: causing the loss of a fetus and causing the death of a pregnant woman.

The death of an unborn child adds an additional charge and penalty of three years more than the maximum penalty under the first offence.

The recognition of the unborn child as a legal person also means the woman or her family members can give victim impact statements in court, and the name of the unborn child can be included on the indictment.

Queensland has also enacted similar laws, although they don’t go quite as far.

Sarah Milosevic was 39 weeks pregnant with Sophie when her car was hit by a driver under the influence in 2014. Sophie died a few days later as a result of injuries sustained in the crash.

The driver was charged and found guilty, but the penalty was a $950 fine. Sophie’s mother campaigned tirelessly for legal change and in September 2023 “Sophie’s law” was passed.

Courts in Queensland are now required to treat the death of an unborn child as an aggravating factor during the sentencing of offenders. The aim is to ensure harsher sentences.

This is in addition to the Queensland Criminal Code, which makes it a crime to unlawfully assault a pregnant woman causing her to lose the child.

While this amendment stops short of recognising unborn children as legal people, it’s at least a step in the right direction.

Call for change

Before the crash, Aldridge had just learned that her son had fully formed lungs. He could arrive healthily any time. She described the heartbreak of discovering Remi wasn’t considered a human being in the eyes of the criminal law.

Failing to recognise the legal status of a unborn child who is killed this way creates significant hardship for families. They’re often already lost in layers of contradictory legal bureaucracy at a very difficult time.

If there can be recognition of legal personhood under administrate law but not under the criminal law, then the legal balance is off and requires readjusting.

NSW faced the same philosophical and moral debates and has been able to pass legislation that successfully addresses concerns. Other states and territories should take note and follow suit.

Legal personhood in Australia should not be determined by postcode.

When dead animals are left lying around in nature, who takes advantage of the free feed – carnivores or herbivores? The answer may surprise you.

In Australia, people tend to think carnivores – such as dingoes, ravens, foxes and wedge-tailed eagles – lead the clean-up crew.

But our new research shows common brushtail possums – often thought to be herbivores – also dine on animal carcasses.

Understanding when and where brushtail possums scavenge is important. It can improve our knowledge of how carcasses are disposed of in nature, and how nutrients cycle through ecosystems.

Seeking a nutritious meal

Scavenging may provide specific essential nutrients otherwise lacking in herbivore diets.

Carcasses often contain much greater levels of crude protein than leafy greens do. Similarly, chewing on bones, may increase the intake of calcium and phosphorus, two key minerals essential for growth.

Scavenging on carrion may also help herbivores meet nutritional requirements in regions where typical food resources may be restricted during some seasons. Similarly, in times of drought, thirst may also drive herbivores to scavenge in an attempt to extract fluids from carcasses.

Though it may seem gruesome, scavenging is crucial to healthy ecosystems. Clearing carcasses from the landscape by feeding them back into food chains recycles nutrients into living systems.

Our previous research has found native marsupial herbivores feasting on the dead.

In alpine Australia, possums accounted for 61% of all recorded carcass scavenging – a proportion far surpassing species more typically considered carcass consumers.

In our latest research, we wanted to understand the factors that influence carrion consumption by brushtail possums in different ecosystems.

What we did

We monitored fresh eastern grey kangaroo carcasses across both alpine (Kosciuszko National Park) and temperate (Wolgan Valley, Greater Blue Mountains National Park) regions in New South Wales. We also compared sites in both open (grassland with no canopy cover) and closed (woodland) habitats, in cool and warm seasons.

At each carcass, we used a remote camera “trap” to record scavenging behaviours.

We found possums were one of the main scavengers, often feeding from carrion more than typical scavengers such as dingoes and ravens.

Possum scavenging rates varied by habitat and season. Regardless of region, possums scavenged exclusively in closed canopy habitats under the trees, probably for protection from predators and other scavengers such as dingoes, red foxes, and wedge-tailed eagles.

Out in the cold

Possum scavenging activity varied according to the season.

In temperate regions, possums scavenged only in winter when other food resources were limited.

In alpine areas, where food is scarce even in summer, possums scavenged year-round. But they still ate more from carcasses in cooler months. This may be necessary for possums to get the nutrition they need when other normal food resources — such as leaves, flowers and fruit — are limited.

Competition between scavengers may also change with the seasons. For example, in alpine regions, we saw fewer large scavengers such as dingoes in winter, possibly reducing competition and making it easier for possums to access carrion.

During warmer months, insect activity increases. These tiny scavengers often start eating a carcass within minutes of its death, accelerating its decomposition. It means animals such as possums have less time to feed on the carrion.

Flexible ‘herbivores’ around the world

Previous research has shown many herbivore diets are more flexible than previously thought. All over the world, certain plant-eaters have been found scavenging on animal remains – especially when other food sources are limited, such as during drought or after fire.

In Africa, hippopotamuses were found to have consumed flesh from the carcasses of other animals. In the United States, white-tailed deer fed on discarded fish.

Similarly, on a small island off Cape Town, introduced European fallow deer ate dead rabbits. On the Eurasian tundra (treeless plains), reindeer devoured lemming carcasses. In Italy, crested porcupine ate dead pigeons.

These are all still primarily herbivorous animals, they just happen to dip into carcass resources when they need to.

Improving our understanding of ‘bloody hungry’ herbivores

Our study found brushtail possums are an important scavenging species across several Australian ecosystems. It also highlights how scavenging can vary with a region, season and habitat.

Understanding the unusual foraging behaviour of the common brushtail possum could also help inform more effective wildlife management. Specifically, understanding how carcasses can support possum populations during cooler months in places like New Zealand, where they are considered an invasive pest, may lead to more effective control measures.

Our methods could also help scientists understand herbivore scavenging in other environments. This may provide valuable insights into complexities of food webs and how nutrients move through ecosystems.

Australia’s tax system is needlessly complex, and that’s making it costly in ways that aren’t obvious.

New research from our team at the Australian National University’s Tax and Transfer Policy Institute, in the Journal of Public Economics, has identified one of the unexpected ways it is wasting our time, and found pretty clear evidence of tax evasion along the way – evidence the Tax Office will be able to use.

Here’s what we did.

Examining 27 years of de-identified individual tax files, we noticed a striking number of returns generating “round number” refunds.

By “round number”, I mean refunds whose last digit is zero.

Zeros are exceptionally popular

We found, for instance, far more refunds of exactly $1,000 than of $999 or $995, or even $1,005 or $1,015.

This phenomenon was particularly striking at zero (many fewer people got refunds of slightly less than zero, which would have meant they owed money) and also apparent at tens and hundreds as well as thousands.

Zeros matter: the number of taxpayers getting each refund

Analysing what the returns with round numbers had in common, we found they were more likely than other returns to be

• driven by efforts to evade and minimise tax rather than simply earn income

• driven by things that are costly for the Tax Office to audit (such as work-related expense deductions).

• prepared by agents (zeros were twice as common in agent-prepared returns)

Next, we matched our data about zeros with data from the Tax Office’s random audit program. We found that, when audited, returns with round number refunds were significantly more likely to be wrong. Specifically, they were more likely to overstate the refund that was owed.

More than a quirky preference

This suggests round number refunds are not just a quirky preference – they signal something going on, most likely something going wrong.

That “something” seems to be the manipulation of claims that are costly to verify, principally work-related expense deductions and business income.

Expense deductions and business income are significantly larger in returns with round number refunds than in those without.

It is important to note we found some tax agents got round number returns a lot while others did it very little or not at all.

More like evasion than planning

When taxpayers switch from “low-rounding” to “high-rounding” agents, we see a one-off hike in the returns those people receive, with no further increases thereafter.

This is likely to mean that agents who specialise in round-number returns are not working with their clients over time to rearrange their affairs to minimise tax or to better document legitimate deductions.

Were that the case, we would see the value of these returns increase over time.

This makes the behaviour of these agents more consistent with tax evasion than tax planning.

We can fight it, or use it as a tool

One simple response to this abuse would be to remove many of the deductions and lower tax rates for everyone.

Another would be to copy the United States and offer all taxpayers a large “standard deduction”, inviting only those that want a larger one to go to the effort of itemising their claims. (The US standard deduction is currently US$14,600 for singles and US$29,200 for couples filing jointly.)

In the meantime, the Tax Office might be able to put our findings to good use.

It could identify the clients the agents who get round number returns as targets for audits. They are more likely than others to be improperly claiming.

In the longer term, this strategy won’t work as well. The agents who have been delivering round number returns will become aware that their clients are being targeted and change their behaviour.

This means that after a while nothing will work as well as tax reform. It would save taxpayers time and make the system more fair for everyone.

The past few months has seen the sudden departure of leadership from some of the country’s most prestigious artistic companies: the Melbourne Symphony Orchestra, Queensland Ballet, Queensland Theatre, Opera Australia and the Adelaide Festival.

These women cited various reasons for leaving, from job opportunities in government, to funding issues, to disagreements with artists and the board.

It certainly seems like a difficult time for arts organisations and their boards.

Australia’s arts and cultural sector has suffered decades of ongoing funding cuts and, until recently, lack of policy direction. Now, the cost of living crisis means participation in arts and culture is seen as a luxury.

Boards and companies become more risk-averse within these tightened financial constraints.

This may be behind the departure of Leanne Benjamin from Queensland Ballet in July. Her appointment as artistic director only six months prior was celebrated as a “perfect fit”.

She described her reasons for her shock exit as:

Ultimately, as we have worked together to design a vibrant season for 2025, it has become very clear that my artistic aspirations for our company […] is not immediately possible within the funding constraints faced by the company.

Jo Davies was Opera Australia’s first female artistic director, coming on board in December 2022. By August 2024, she described:

a real difference of opinion on how [Opera Australia] should balance its artistic ambitions with its commercial imperative.

Opera Australia chair Rod Sims put it more bluntly:

Obviously any artistic director wants free rein to spend whatever they want and do whatever they want, and that must also always go through a financial filter, in any arts company.

A volunteer board

Emotions can run high in arts companies, where (underpaid) staff and (unpaid) volunteers donate their time, expertise and passion to deliver experiences for their audiences.

While some arts boards in Australia are paid an honorarium, most arts organisations are headed by volunteer-run boards. The makeup of boards has also been changing. Recent decades have seen an increase of leaders from the corporate sector on arts boards, especially on those that are government-appointed.

Research shows most board members enjoy their association with arts companies. However, arts consultant Kate Larsen has found that 58% of members of Australian arts boards “do not understand what their organisations need from them at all”.

Board members tend to come from very different socioeconomic and professional backgrounds than paid members of staff, and have limited exposure to the day-to-day running of an arts company.

They do, however, carry the weight of responsibility for the company’s big-picture strategic and financial directions.

Perhaps this is the mismatch we’re seeing between boards and arts leaders such as Benjamin and Davies.

Capturing what we value

There are three different facets to what we know as “cultural value”: intrinsic value, instrumental value and institutional value. I believe we are currently seeing an imbalance between these three types of value.

Intrinsic value is the intellectual, emotional and spiritual value of experiencing culture for audiences and artists.

Instrumental values are the coincidental impacts or effects, usually recorded in numbers, such as an increase in tourist visits or mental health outcomes. Often embedded in cultural policy, instrumental impacts are given greater weight than artistic outcomes in evaluation and acquittals for government funds.

Institutional value reflects how cultural institutions and organisations relate to and engage with their public over the long term, becoming active agents in the creation or destruction of what the public values.

We are currently witnessing a clashing of priorities.

At Queensland Ballet and Opera Australia, we’ve seen a mismatch between the financial priorities of the board and the artistic priorities of leadership. The storm at the Melbourne Symphony Orchestra can be seen as a risk-averse team, sensitive to current political concerns, overreacting in the absence of board support.

I believe we are seeing a diminishing of institutional value in many corners of the sector. Decades of funding cuts means arts companies and cultural institutions understandably step away from perceived risks to their relationships with audiences and sponsors, and make more conservative programming decisions.

This response limits the public’s opportunities to experience new works, and puts the core creative business of an arts company or institution at risk. Economic performance, rather than artistic endeavour, takes centre stage. If that is the whole company’s priority, all well and good. But at Opera Australia and Queensland Ballet, it seems this priority could have come at the expense of their artistic directors.

Uniting strong governance and artistic risk

No one wants our cultural sector hamstrung by instrumentality and shifting government policy flips. Arts companies and cultural institutions require ongoing support and public understanding of their role so they can be confident to take risks – artistically and financially – and provide the public with opportunities to learn, grow and embrace a diversity of cultures, people and experiences, within the safety of a theatre, gallery, concert hall or festival.

To fulfil their role as mediators and generators of knowledge and understanding for the public, companies must be equipped and backed up by their boards to deal with these responsibilities.

A job position description for the role of artistic director for Queensland Theatre describes the board as “an enabling force of strong governance”.

Arts companies and cultural institutions need the participation and support of an army of advocates, audiences and ambassadors across the community to survive. There are promising steps being made at the federal level to enable artistic vision and courageous leadership for the Australian cultural sector – but there is still a long way to go.

This is both the challenge and opportunity facing everyone across all levels of the Australian cultural sector, and they have to face it together.

Good girl! Good boy!

Parents, relatives and teachers say these phrases all the time and mean them positively.

They may use it when a child puts on their shoes when asked, when they draw something interesting, or get a maths question correct.

But this kind of language may not always be healthy or helpful. One issue is it doesn’t actually give children clear feedback on what they just did or said.

What could you say instead?

Praise and parenting

Praise has been seen as a key part of raising children for decades. In the 1950s, influential US psychologist B.F. Skinner believed rewards, including praise, positively reinforce desired behaviours.

In the 1970s, amid rising interest in self-esteem, psychologists and other child development experts emphasised the importance of praising children.

But since the 2000s, psychology research has moved away from seeing self-esteem, and hence praise, as central to a child’s wellbeing.

Early childhood education has similarly shifted towards children having a positive sense of identity instead. This means children having a sense of safety, belonging and capability, rather than a strong opinion of themselves.

Nevertheless, praise is still frequently mentioned in popular advice to parents.

Different kinds of praise

Some psychology researchers have defined praise as either informational (telling children about their strengths and actions) or evaluative (telling children whether or not they are good enough).

In a similar vein, US psychologist Carol Dweck categorises praise as “person praise” or “process praise”.

Person praise focuses on stable characteristics such as personality or appearance. Process praise focuses on behaviours or effort directed towards achieving an outcome, such as learning to ride a bike or a baby taking first steps.

Research has found person praise can decrease young children’s motivation to challenge themselves and lead to feelings of helplessness if they fail.

In contrast, a long-term study of children whose mothers used process praise showed these children were more likely to be confident in preschool and later in primary school.

Process praise is informational, giving children feedback on their efforts and strategies in achieving an outcome (“I can see by your puffing how hard you ran in that race”). Person praise tends to be evaluative, often where there is little possibility for change, or only after success (“What a winner!”).

Seeking approval or seeking improvement?

More broadly, constant praise may mean children unconsciously feel they are doing things for adult approval, rather than for themselves.

This can work against the development of self-regulation and a healthy sense of identity.

Adults who over-praise (particularly evaluative or person-focused praise) may assume children need external rewards to do the right thing. This doesn’t enable children to make good choices on their own.

Recent research suggests inflated praise, using words such as “incredible”, “amazing” and “wonderful”, can foster narcissistic traits by causing children to have an unrealistic sense of their own competence.

This can lead children to become upset or angry at failure, partly because they perceive their worth to be conditional on meeting adults’ standards. So, counterintuitively, inflated praise can lower self-esteem.

The gender question

“Good girl/boy” also raises other issues around gender identity and self-esteem.

Research involving adults found men are more likely to see praise as informational (reflecting their competence) whereas women are more likely to see praise as evaluative (implying their need to conform to set ways of behaving).

Studies of children that compared boys’ and girls’ responses to praise also found girls tended to respond more negatively to evaluative praise.

While some of this research is decades old and done in the United States, it is interesting to think about why this might be, and whether it relates to how we socialise children into gender roles. What kind of unconscious messages are we communicating through our praise?

What should parents be doing instead?

Three principles can support a healthy approach to praising kids.

1. Give children realistic feedback about their behaviour or actions. For example, “Well done. I can see you’re trying there with your kicks” as opposed to “Amazing kicking! You’re a superstar!”

2. Focus on children’s own learning or improvement rather than on competing with others For example, “Next time, when you play that piece, how about trying it faster?” rather than “That wasn’t as quick as Sophia can play it”.

3. Use praise that shows children they are valued regardless of what they may or may not do. For example, “Well done! I know you studied every day for this test” as opposed to “You’re Dad’s straight-A angel!”

These approaches all support confidence, empathy and resilience in children – qualities we all need in our complex world.

The budget surplus for last financial year has come in at $15.8 billion, well exceeding the $9.3 billion that was forecast in the May budget.

Treasurer Jim Chalmers, just back from talks in Beijing on China’s economic outlook, will announce the result on Monday.

The government says the better-than-forecast outcome has been driven entirely by lower spending. Revenue was also lower than the budget anticipated. Areas of savings included the National Disability Insurance Scheme, payments to the states, and various grant programs that don’t exist anymore.

This is the government’s second consecutive surplus. The May budget has predicted deficits for the coming years.

Across 2022-23 and 2023-24 the budget position has improved by a cumulative $172.3 billion, compared with what was forecast in the official Pre-election Economic and Fiscal Outlook, released immediately before the 2022 election.

The government says it has made $77.4 billion in savings, including $12.2 billion in 2023-24.

Payments were 25.2% of GDP in 2023-24. This compared to the PEFO forecast of 27.1%

Chalmers said this was the “first government to post back-to-back surpluses in nearly two decades”. The surpluses hadn’t come at the expense of cost-of-living relief, he said in a statement.

Speaking in Beijing on Friday Chalmers said it remained to be seen whether China’s just-announced stimulus measures would work.

“But we’ve seen on earlier occasions when the authorities here, the administration here, steps in to support activity in the economy that is typically a good thing for Australia – good for our businesses and workers, our industries, our investors, and good for the global economy as well.

“Like a lot of people around the world, we have been concerned about the softer conditions here in the Chinese economy. Subject to the details [of measures] that will be made public in good time, any efforts to boost growth and support activity here is a welcome one around the world and especially at home in Australia.”

Chalmers on Monday is likely to face further questions on the Treasury’s work on negative gearing, news of which leaked out last week.
