Ever since AUKUS’ public announcement three years ago, China has been staunchly opposed to the partnership.

Beijing has blasted AUKUS diplomatically and mounted a concerted campaign to challenge its legality.

China has said AUKUS is “driven by Cold War thinking,” “fuelling military confrontation,” and creating “additional nuclear proliferation risks”.

The aim of AUKUS is for the Australian navy to acquire nuclear-powered submarines, with Australia, the United Kingdom and the United States also collaborating on other advanced military technologies.

As AUKUS sceptics have argued, it’s entirely possible Australia will never get its planned nuclear-powered attack submarines. Any number of factors — from the mercurial whims of a future US president to American shipbuilding constraints — could see the partnership fall over.

However, if the plan succeeds, even in a modified form, it’ll pose a serious military challenge to China. As Kevin Rudd, the former Australian prime minister and current ambassador to the US, said in recent days, it’s probably already complicating China’s future geopolitical calculations.

When Chinese military analysts look at the geopolitical picture, they see it more clouded and cluttered than they did before.

Here are three reasons why China finds the pact so threatening.

1. Complicating China’s nuclear strategy

AUKUS submarines will not be armed with nuclear warheads. But these boats could be used to endanger China’s sea-based nuclear weapons.

China currently operates six submarines that are both nuclear-powered and capable of launching nuclear weapons. These are based on Hainan Island, where they enjoy the protection of hardened bases. They can quickly reach the deep waters of the South China Sea to reduce the likelihood of detection.

Monitoring China’s nuclear weapons-capable submarines as they leave Hainan Island is likely to be among the most important of the many missions for the AUKUS boats.

The increased speed, stealth and endurance of AUKUS submarines mean they’d be able to reach the South China Sea quicker. Once there, they can stay “on station” undetected for much longer.

This peacetime monitoring of China’s nuclear weapons-capable submarines would help build a better understanding of their hydro-acoustic signatures and thereby make these Chinese boats more vulnerable to detection.

Combined with the intelligence gathered by Australia’s regular South China Sea maritime air patrols, AUKUS submarines could eventually enhance the ability of the Australian and allied militaries to track and, in conflict scenarios, attack China’s sea-borne nuclear deterrent.

2. A direct military threat to China

Foreign Minister Penny Wong has said in connection to AUKUS that Australia needs to be able to “hold potential adversaries’ forces and infrastructure at risk from a greater distance”.

She might not have mentioned China in the same breath. But like many Australians, military planners in Beijing would imagine China is the most probable target.

Likely armed with Tomahawk cruise missiles capable of striking land, AUKUS submarines could be used to target Chinese military bases and infrastructure in the South China Sea and along the country’s east coast.

AUKUS submarines could also constrict China’s access to the economic inputs essential for warfighting. China remains acutely dependent on Indian Ocean and East Asian shipping lanes for imports of oil and other resources. The ability of AUKUS submarines to travel vast distances without surfacing or refuelling could allow them to threaten China’s vital maritime supply routes in conflict scenarios.

Beijing might even imagine that AUKUS submarines could be used to directly attack Chinese cities in an all-out war. This might seem far-fetched for now, but with military planning often dealing with worst-case scenarios, Chinese defence strategists are probably considering this possibility.

3. Further tipping the regional military balance

Australia is expected to buy at least three – and possibly as many as five – Virginia-class submarines from the United States in the next decade and a half.

These boats might have otherwise gone into the US fleet, meaning that until 2040 and perhaps even beyond, the size of the American nuclear-powered submarine force could be smaller than it would have been without AUKUS. And there is still much uncertainty surrounding the political and industrial feasibility of both the planned sale of Virginia-class submarines and the construction of a new AUKUS class of boat.

But assuming it’s successful, AUKUS will substantially increase the total number of nuclear-powered submarines operated by the US and its allies from around the 2040s onwards, potentially giving them a long-term undersea military advantage over China.

In the near term, AUKUS could also enable the deployment of additional high-end US and allied military platforms to the region.

Of course, this isn’t just an AUKUS story. Australia will welcome more US bombers and fighter aircraft in the coming years, and we’ll likely see larger US forces in Japan and the Philippines, among other locations.

Still, the establishment of Submarine Rotational Force – West under the AUKUS plan will see a big boost to US and allied military power in the region. It’s expected to involve the rotational presence of one UK and up to four US nuclear-powered submarines in Western Australia from 2027.

This might mean a weakening of China’s relative submarine strength in the region regardless of what happens with the eventual delivery and construction of nuclear-powered submarines for Australia.

This is not a complete account of all the reasons China might have for opposing AUKUS. But these three factors alone suggest the partnership has the potential to pose a significant and long-term military challenge to Beijing.

Earth’s majestic “apex predators” are some of the most prolific hunters in the world. But which ones kill the most?

Our new research showed solitary hunters such as bears, tigers and Eurasian lynx have higher individual kill rates than social predators such as wolves and lions. And smaller species, such as cheetahs and pumas, tend to kill relatively more prey because their kills are often stolen by more dominant carnivores.

Such information allows us to better understand how different predators affect their environment. It can also guide hunting quotas and help evaluate how humans affect carnivores.

These apex predators perform vital roles in ecosystems. Yet tragically they are among the world’s most threatened animals. Carnivores frequently come into conflict with humans, particularly over livestock and public safety.

Our approach

Our research was a systematic, world-first literature review into the predatory behaviour of large land-based carnivores. In particular, we examined carnivore “kill rates” – the number of prey killed over time. We did this to better understand their foraging and impacts on prey populations and ecosystems.

We examined 196 papers that either quantified large mammal carnivore kill rates, or reported data we could use to calculate the rates ourselves.

We focused on the large land-based carnivores weighing 15 kg or more. We also searched for kill rate studies on four smaller species — coyote, wolverine, fossa (a cat-like predator found in Madagascar) and the Tasmanian Devil — as they’re all considered apex predators in certain regions and ecosystems.

We only found kill rate estimates for 17 (55%) of the 31 carnivore species included in our review. Studies came from 27 countries across five continents.

Carnivores hunt in different ways

We found kill rates differ between carnivores with different social structures and hunting strategies.

Social predators, such as wolves and lions, tend to kill fewer animals per carnivore than solitary hunters such as bears, tigers and Eurasian lynx. For example, on average grey wolves made a kill every 27 days per wolf, compared with every four days per Eurasian lynx.

Larger wolf packs can bring down large animals such as bison more easily. Similarly, groups of cheetahs can tackle larger prey than solitary cheetahs. This could mean they don’t need to hunt as often.

Working as a team may also reduce losses to scavengers, as groups can better defend their kills through sheer numbers. Or they might be better at scavenging and stealing (“kleptoparasitism”) from others.

Canine predators such as wolves and African wild dogs often rely on high-energy pursuits over long distances. For example, grey wolves can pursue prey for more than 20km. In contrast, cats rely on stealth, using an ambush hunting strategy. This saves energy.

Solitary large carnivores such as tigers, leopards and Eurasian lynx, which mainly hunt hooved mammals, have similar kill rates regardless of body mass. This suggests large land-based carnivores are compelled to hunt prey closer to their own size or larger, to compensate for the energy used in the hunt.

Smaller carnivores such as cheetahs, pumas and African wild dogs often kill more prey than their larger counterparts, but only consume about half of what they kill.

This behaviour benefits other species such as lions, bears and wolves and is likely a consequence of having to compensate for the theft and loss of food. Pumas are thought to provide more than 1.5 million kilograms of carrion a day across North and South America.

If you’ve seen the Lion King movie, you’d be forgiven for thinking hyenas largely steal and scavenge their food. But that’s not the case. Lions often steal from hyenas, as well as from other carnivores such as cheetahs and African wild dogs.

Bias in kill rate research

More than half (55%) of all kill rate studies have been conducted in North America. Africa follows with almost a quarter (24%), then Europe (12.5%).

Asia was a long way behind with 7% of all kill rate studies. That’s just 13 studies covering six species. This is despite being the largest continent, home to 17 (55%) of the 31 large carnivore species included in our review.

No reliable kill rate studies have been published from Australia.

A third (33%) of all kill rate studies focused on grey wolves, followed by pumas (20%), lions (12%) and Eurasian lynx (8%). This means we know little about the predatory behaviour and roles of other large carnivores.

Grey wolves are considered a threat to livestock and wildlife that humans value. This has prompted significant investment in research to understand their predatory behaviour and that of other large North American carnivores.

Such work has subsequently been used to inform appropriate management and conservation of these predators and their prey.

Carnivores bring benefits

Kill rate studies provide more than just a tally of carnivore behaviour. They offer deeper insights into the relationships between predators and prey, and their effects on ecosystems.

Large carnivores shape ecosystems by scaring and killing prey, which can change their behaviour, distribution and abundance. They also supply food to other species, affecting the flow of nutrients and energy.

In many ways, large carnivores also help people. They can reduce the risk of vehicle collisions, by killing deer that might otherwise wander onto roads. They may limit the spread of disease by preying on sick animals, and control herbivores, aiding livestock producers.

Yet carnivores, including Australia’s dingo, are still widely persecuted. We need to do all we can to maintain their pride of place at the pinnacle of Earth’s ecosystems.

Of course, if you really want to know which species is the biggest killer, it’s humans. We are the dominant predator across Earth.

Just four years ago, experts warned te reo Māori was on a “pathway towards extinction” unless resources were put into teaching young Māori.

But a new mathematical model combined with recent data suggests the future of Māori language is not as grim as it once was.

My ongoing research looks at the future trajectory of Māori language acquisition over the next few decades. Based on recent data, my model suggests the Māori language could be on a path to recovery.

For over 50 years, revitalisation efforts have played a significant role in supporting the language’s resurgence.

The progress of te reo Māori provides hope for campaigners working to save the 55% of world languages destined to be dormant, doomed, or extinct by the end of the century.

Rescuing te reo Māori

Māori revitalisation efforts began in earnest in the late 1970s. The first kōhanga reo was opened in 1982, and te reo Māori was made an official language under the Maori Language Act 1987.

Despite these efforts, there have been ongoing concerns about the sustainability of the language. According to the 2018 Census, just 4% of New Zealanders reported they were fluent speakers of te reo Māori, up from 3.7% in 2013.

In the General Social Survey (also based on self-reported data), the number of people able to speak te reo Māori, at least fairly well, increased – from 6.1% in 2018 to 7.9% in 2021.

This was the first time there was a significant increase in this level of te reo Māori proficiency.

In 2019, the Labour government committed to the revitalisation of te reo Māori by setting a national target of one million speakers (at any level of proficiency) by 2040.

Modelling the future

My research is based on several sources of data – including the Census, the General Social Survey and the Te Kupenga survey of Māori wellbeing. The goal is to model how many speakers of te reo Māori we can expect in 20 or 30 years.

To understand this future path, I use my model to create different possible trajectories and compare them to these data sources. After finding the trajectories that best match, I extend these trajectories into the next few decades to estimate how many people might speak te reo in the future.

Some of the data, particularly from the more recent General Social Survey and the number of students learning te reo in schools and at university level, pointed to growth in te reo Māori acquisition. For example, enrolments in tertiary te reo courses have increased by 93% over the past ten years.

According to the model and current data, achieving one million speakers by 2040 is within reach, but it will take an increased commitment from the government and communities to make this future more likely.

A ‘forever language’ – te Wiki o te Reo Māori marks 52 years of extraordinary progress

Developing policies to help

The next step of the research will be to better understand the role of government policy, iwi and the public in encouraging the adoption of te reo Māori.

Such policies include more te reo Māori in schools, providing more access to university-level te reo courses, encouraging fluent speakers to become teachers, increasing the use of bilingual signs, and promoting the use of te reo Māori at home.

But these are not the sort of policies we can expect from the current government, which has actively discouraged the official use of te reo Māori and is working to reduce incentives for public servants to learn the language.

This year’s Wiki o te Reo Māori (Māori Language Week) also comes amid an ongoing debate around the constitutional role of Te Tiriti o Waitangi (Treaty of Waitangi).

There is likely enough momentum within the reo community to keep the language growing in the short term. But if these policy settings were to continue (or worsen) over several years, it could have a negative effect on the future trajectory of te reo.

There are a lot of Indigenous languages being lost at the moment. Research has shown this can cause irrevocable harm for the communities they belong to.

It is important for the wellbeing of Māori that their language and culture are preserved. And it benefits all New Zealanders to have an understanding of one of the foundational languages of the country.

Based on the modelling, the future is looking hopeful in this respect.

When it comes to our experience of the internet, “the times, they are a-changin’”, as Bob Dylan would say. You can’t quite recall how, but the internet certainly feels different these days.

To some, it is “less fun and less informative” than it used to be. To others, online searches are made up of “cookie cutter” pages that drown out useful information and are saturated with scams, spam and content generated by artificial intelligence (AI).

Your social media feeds are full of eye-catching, provocative, hyper-targeted, or anger-inducing content, from bizarre AI-generated imagery to robot-like comments. You’re lucky if your video feeds are not solely made up of exhortations to “subscribe”.

How did we get here? And can we claw our way back?

Commercial interests rule

One major factor contributing to the current state of the internet is its over-commercialisation: financial motives drive much of the content. This has arguably led to the prevalence of sensationalism, prioritising virality over information quality.

Covert and deceptive advertising is widespread, blurring the line between commercial and non-commercial content to attract more attention and engagement.

Another driving force is the dominance of tech giants like Google, Meta and Amazon. They reach billions worldwide and wield immense power over the content we consume.

Their platforms use advanced tracking technologies and opaque algorithms to generate hyper-targeted media content, powered by extensive user data. This creates filter bubbles, where users are exposed to limited content that reinforces their existing beliefs and biases, and echo chambers where other viewpoints are actively discredited.

Bad actors like cyber criminals and scammers have been an enduring problem online. However, evolving technology like generative AI has further empowered them, enabling them to create highly realistic fake images, deepfake videos and voice cloning.

AI’s ability to automate content creation has also flooded the internet with low-quality, misleading and harmful material at an unprecedented scale.

In sum, the accelerated commercialisation of the internet, the dominance of media tech giants and the presence of bad actors have infiltrated content on the internet. The rise of AI further intensifies this, making the internet more chaotic than ever.

Some of the ‘good’ internet remains

So, what was the “good internet” some of us long for with nostalgia?

At the outset, the internet was meant to be a free egalitarian space people were meant to “surf” and “browse”. Knowledge was meant to be shared: sites such as Wikipedia and The Internet Archive are continuing bastions of knowledge.

Before the advent of filter bubbles, the internet was a creative playground where people explored different ideas, discussed varying perspectives, and collaborated with individuals from “outgroups” – those outside their social circles who may hold opposing views.

Early social media platforms were built on the ethos of reconnecting with long-lost classmates and family members. Many of us have community groups, acquaintances and family we reach out to via the internet. The “connection” aspect of the internet remains as important as ever – as we all saw during the COVID pandemic.

What else do we want to preserve? Privacy. A New Yorker cartoon joke in 1993 stated that “on the internet, nobody knows you’re a dog”. Now everyone – especially advertisers – wants to know who you are. To quote the Office of the Australian Information Commissioner, one of the tenets of privacy is “to be able to control who can see or use information about you”.

At the very least, we want to control what big tech knows about us, especially if they could stand to profit from it.

Can we ever go back?

We can’t control “a changin’” times, but we can keep as much of the good parts as we can.

For starters, we can vote with our feet. Users can enact change and bring awareness to problems on existing platforms. In recent times, we have seen this with the exodus of users from X (formerly Twitter) to other platforms, and the platform-wide protest against Reddit for changing its third-party data access policies.

However, voting with our feet is only possible when there’s competition. In the case of X, various other platforms – from Mastodon to Threads to Bluesky – enable users to pick one that aligns with their preferences, values and social circles. Search engines have alternatives, too, such as DuckDuckGo or Ecosia.

But competition can only be created by moving to decentralised systems and removing monopolies. This actually happened in the early days of the internet during the 1990s “browser wars”, when Microsoft was eventually accused of illegally monopolising the web browser market in a landmark court case.

As users of technology, all of us must remain vigilant about threats to our privacy and knowledge. With cheap and ubiquitous generative AI, misleading content and scams are more realistic as ever.

We must exercise healthy scepticism and ensure those most at risk from online threats – such as children and older people – are educated about potential harms.

Remember, the internet is not optimised for your best interests. It’s up to you to decide how much power you give to the tech giants who are fuelling theirs.

Last week, some 2,000 government officials and experts from around the world met for the REAIM (Responsible Artificial Intelligence in the Military Domain) summit in Seoul, South Korea. This was the second event of its kind, with the first one held in the Netherlands in February 2023.

During this year’s summit, 61 countries endorsed a “Blueprint for Action” for governing the development and use of artificial intelligence (AI) by the military.

However, 30 countries sent a government representative to the summit but didn’t endorse the blueprint, including China.

The blueprint is an important, if modest, development. But there is still a gap in the understanding of what constitutes responsible use of AI and how this translates into concrete actions in the military domain.

How is AI currently used in military contexts?

Military use of AI has increased over the last few years, notably in the Russia-Ukraine and Israel-Palestine conflicts.

Israel has used AI-enabled systems known as “Gospel” and “Lavender” to help it make key military decisions, such as which locations and people to target with bombs. The systems use large amounts of data, including people’s addresses, phone numbers and membership of chat groups.

The “Lavender” system in particular made headlines earlier this year when critics questioned its efficacy and legality. There was particular concern around its training data and how it classified targets.

Both Russia and Ukraine also use AI to support military decision making. Satellite imagery, social media content and drone surveillance are just some of the many information sources which generate copious volumes of data.

AI can analyse this data much more quickly than humans could. The results are incorporated into existing “kill chains” – the process of locating, tracking, targeting and engaging targets.

It means military officials can make faster decisions during active armed conflict, providing tactical advantages. However, the misuse of AI systems can also result in potential harm.

Civil society and non-governmental organisations such as the International Committee of the Red Cross have warned about the risks. For example, algorithmic bias can exacerbate the risk to civilians during active warfare.

What is responsible AI in the military domain?

There is no consensus on what constitutes “responsible” AI.

Some researchers argue the technology itself can be responsible. In this case, “responsible” would mean having built-in fairness and freedom from bias.

Other studies refer to the practices around AI – such as design, development and use – being responsible. These would mean practices that are lawful, traceable, reliable and focused on mitigating bias.

The blueprint endorsed at the recent summit in Seoul aligns with the latter interpretation. It advocates that anyone using AI in the military must comply with relevant national and international laws.

It also highlights the importance of human roles in the development, deployment and use of AI in the military domain. This includes ensuring human judgement and control over the use of force are responsibly and safely managed.

This is an important distinction, because many narratives around AI falsely imply an absence of human involvement and responsibility.

What can governments do to use military AI responsibly?

Discussions at the summit focused heavily on concrete steps governments can take to support responsible use of military AI.

As military AI use is currently increasing, we need interim steps to deal with it. One suggestion was to strike AI regulation agreements within different regions, rather than taking longer to reach a global, universal consensus.

To improve global cooperation on military AI, we could also heed lessons from previous global challenges – such as nuclear non-proliferation, saving the ozone layer and keeping outer space and Antarctica demilitarised.

Eighteen months since the inaugural summit last year, governments and other responsible parties have started putting into place risk-mitigation processes and toolkits for military AI.

The blueprint reflects the progress since then, and the ideas discussed at the summit. It proposes a number of tangible steps, which include:

• universal legal reviews for AI-enabled military capabilities
• promoting dialogue on developing measures to ensure responsible AI in the military domain at the national, regional and international levels
• maintaining appropriate human involvement in the development, deployment and use of AI in the military domain.

However, progress is slow because we still don’t have a universal understanding of what responsible military AI actually looks like.

The need to cut thorough these issues is now putting pressure on the next summit (not yet announced). The Netherlands has also set up an expert body to further a globally consistent approach to military AI.

Humanity can benefit from AI tools. But we urgently need to ensure the risks they pose don’t proliferate, especially in the military domain.

Domestic, family and sexual violence is rightly recognised as a national crisis.

While the evidence base has built significantly in recent years, one important missing piece of the puzzle is how these forms of violence have impacted people who die by suicide across the country.

Data released this week by the Coroner’s Court of Victoria provides a detailed account of the experiences of family violence among people who have died by suicide.

The statistics are alarming. They remind us of what many working in this space already instinctively knew: the horrifically high count of lives lost to the national crisis of men’s violence against women is likely far higher than official numbers suggest.

What does the report tell us?

This latest report presents data collected by the Victorian Suicide Register on 4,790 suicides reported between 2009 and 2016.

Over this period, in one in four suicides (24.5%) the deceased had experienced family violence prior to their death.

This rate was higher among females who died by suicide, with evidence of family violence present in 28.2% of cases recorded.

This rate only captures the cases in which evidence of family violence could be identified by the court.

Given all forms of family violence are under reported, including to police, legal and other services, this data are likely to underestimate the true rates of family violence experienced by people who die by suicide.

Where there was evidence of family violence prior to the suicide, in half of these the person who died by suicide was the perpetrator of violence.

In one in three cases, the individual who died by suicide had experienced family violence victimisation. In these cases, the deceased was significantly more likely to be a female (62.1%).

The report also records a further 17.5% of suicides where the individual who died by suicide had both used and been a victim of family violence. Little information about this group is provided.

We need to better understand the primary use of violence in these situations, including whether this data includes incidents of misidentification and what the impact of it was. The role of intergenerational experiences of abuse should also be considered.

Gendered abuse

The report highlights gender differences in the records of people who died by suicide in Victoria during this period.

Significantly more males (65%) than females (16%) were recorded as a family violence perpetrator. Conversely, females were significantly more likely to be listed as a victim of family violence (62.1%).

These differences are expected given the gendered nature of family violence. Internationally, research has consistently highlighted the higher risk of suicidality and self-harm among women victims of violence.

The data show just over one in two male perpetrators of family violence who die by suicide had used violence against an intimate partner.

A higher proportion of men (22.1%) who died by suicide than women (10.2%) had perpetrated family violence against numerous people, including a partner and at least one other family member.

The data also show female victims of family violence who died by suicide were more likely to have experienced family violence by their intimate partner.

By contrast, male victims were more likely to have experienced family violence perpetrated by a family member other than their partner.

Many factors at play

The report provides insights into how family violence and suicide interact with other social issues.

While the report doesn’t discuss causation, it does look at prevalence of mental health diagnoses. Nearly three quarters of victims of family violence who later died by suicide had been diagnosed with a mental illness at some point in their lives (72.5% among males, 78.2% among females).

The rate of substance misuse was reported as higher among people who had experienced family violence than among the general Victorian suicide population.

Victims and perpetrators of family violence who died by suicide were more likely to be under financial stress when compared to the broader Victorian suicide population.

This was defined as any evidence of stress or harm relating to the deceased’s financial situation. For example, high debts, loss of money, inability to pay mortgage or bills or afford other costs of living, and gambling-related harms. This is a timely finding given the current cost of living crisis and the need to understand where additional support services may be needed.

More than 60% of male family violence perpetrators who died by suicide in the period studied had experienced at least one legal stressor prior to their death. This included involvement in criminal and civil legal processes, including divorce settlements and child custody cases.

Reflecting the harmful impacts the legal system can have on victims, legal stressors were also present in more than a third of the lives of victims of family violence who died by suicide.

Coordination and consistency is key

This data represents an important step forward in quantifying the prevalence of family violence among individuals who died by suicide in one Australian state.

But this violence is a national problem. This data are needed for every Australian state and territory. We simply cannot seek to effectively address and prevent what we do not measure.

Following the recommendations of the recent federal rapid review, there needs to be greater coordination at the commonwealth, state and territory levels to gather this data in the same way in every jurisdiction.

Knowing the impact that experiences of family violence may have had on someone’s suicide is also important to understand. This data doesn’t examine the time frame of experiences, nor their proximity to the person’s death. These are crucial factors to inform prevention strategies.

The more we know about how victims experience and interact with services, the more informed early intervention and response efforts can be. It’s likely victims would have encountered a range of different services before they died.

Each of these points is an important opportunity for intervention. Greater understanding, including of what role family and friends may play in supporting their loved ones to seek help, can be used to inform more effective suicide prevention efforts.

First and foremost, each of these lives matter. And they represent additional lives lost in Australia’s national crisis of domestic, family and sexual violence. Current efforts to prevent femicide in Australia should extend to accounting for, and better understanding deaths by suicide following family violence.

The National Sexual Assault, Family and Domestic Violence Counselling Line – 1800 RESPECT (1800 737 732) – is available 24 hours a day, seven days a week for any Australian who has experienced, or is at risk of, family and domestic violence and/or sexual assault.

At least three decades of research on the intersection of substance use with domestic and family violence consistently shows the frequency, severity and impact of violence increases in the context of the perpetrator using alcohol and other drugs.

Some 24–54% of domestic and family violence incidents reported to police in Australia are classified as alcohol-related, while other drugs are implicated in 1–9% of incidents. This is consistent with international evidence which shows substance use occurs with domestic and family violence in 25–50% of cases.

Several studies have also pointed to the increased severity of domestic and family violence when substances are involved. An Australian study, which looked at 240 women murdered by a current or former male partner between 2010 and 2018, reports more than 60% of the male perpetrators were affected by alcohol or drugs during the fatal episode.

Other research indicates alcohol-related domestic and family violence is two to three times more likely to involve severe physical violence such as life-threatening injuries and broken bones, compared to domestic and family violence where alcohol is not involved.

Our research, however, is interested specifically in the role alcohol and other drugs play in perpetrators’ tactics of violence and abuse. This is sometimes called “substance use coercion” and is a type of coercive control.

Understanding substance use coercion

Coercive control is a repeated pattern of emotional, verbal, sexual, financial or technology-enabled abuse that creates fear and exerts control over another person.

A set of national principles seeking to address coercive control in family and domestic violence recognise that substance use can be exploited in the same way as technology or financial abuse.

Our work identifies several ways perpetrators may use alcohol or other drugs as a form of coercive control, or, in other words, exploit their own substance use to gain more power. These include:

• to excuse their violence (“The drink made me do it”)

• to shift the focus from their abuse to other issues (“I have a drug problem, that’s more important”)

• to control others through their substance use. For example, when a person using violence is intoxicated or in withdrawal, victim-survivors often comply with their demands or avoid arguments to de-escalate the violence.

Perpetrators may also weaponise victim-survivors’ substance use. Research shows that, to numb the physical and emotional pain of family violence, victim-survivors may start using substances.

Perpetrators often encourage this practice to increase their power and control over the victim-survivor and to undermine their credibility if authorities become involved.

Likewise, perpetrators may exacerbate victim-survivors’ existing substance use, such as by pressuring them to drink or take drugs more often. Alternatively they might sabotage victim-survivors’ recovery efforts, preventing their access to treatment services.

Another tactic involves lying about the nature and extent of the victim-survivor’s substance use. This can undermine their credibility with authorities such as child protection services or the family court.

Children suffer too

On a basic level, children are terrified when they hear their father come home drunk and abusive. They fear for both themselves and their mothers, often finding the abuse that follows leaves them with neither parent in a position to look after their needs.

They may also be implicated in their father’s substance use coercion. For example:

Unless you shut those kids up, I’m going to drink.

The severe impact on children living with violence where either or both parents are substance-affected can be seen through child protection data.

A recent New South Wales study reported on children living in situations of domestic and family violence. Children where one or both parents had either substance use issues or poor mental health were three times more likely to be identified as at risk of harm warranting statutory intervention, than in cases of domestic and family violence alone.

Children in situations where substance use and domestic and family violence intersect are some of the most vulnerable in Australia.

What can we do?

Policy and practice responses to the intersection of domestic violence and substance use, both in Australia and internationally, have tended to focus on single issues: domestic violence or substance use.

While many families experience domestic violence and substance use as profoundly intertwined, service systems often fragment their experiences, treating the two as disconnected problems.

Our research is exploring how these two highly siloed sectors can work together, in the form of a 17-week group program for fathers who used violence and abuse in the context of substance use. These men had more significant histories of violence and abuse than men in a similar program targeting violence only.

International evidence shows programs that address both substance use and domestic violence are developed but rarely sustained, despite evidence of their effectiveness.

We would like to see more nuanced policy and practice that recognises the complex crossover between domestic and family violence and substance use. Importantly, these approaches must address children’s experiences of these intersecting issues, and provide tailored responses to promote their safety.

The National Sexual Assault, Family and Domestic Violence Counselling Line – 1800 RESPECT (1800 737 732) – is available 24 hours a day, seven days a week for any Australian who has experienced, or is at risk of, family and domestic violence and/or sexual assault.

It’s not easy finding food at sea. Seabirds often stay aloft, scanning the churning waters for elusive prey. Most seabirds take fish, squid, or other prey from the first few metres of seawater. Scavenging is common.

But there are other tactics. Frigatebirds, skuas, and gulls rely on the success of other seabirds. These large, strong birds chase, harry, and attack their targets until they regurgitate or drop the prey they’ve just caught. They’re the pirates of the seabird world, stealing hard-earned meals from other species. This behaviour is known as kleptoparasitism, from the Ancient Greek word kléptēs, thief.

The strategy is brutal, effective, and a core behaviour for these important seabirds. But as our new research shows, it comes with major risks for the thieves. The new strain of avian flu is killing birds by their millions – and we found kleptoparasitism could spread the virus very easily.

Food thieves at sea

It’s not that frigatebirds, skuas, and gulls can’t hunt. They can and do catch their own food. But hunting fish and squid is hard work. It’s much easier to use extortion tactics to win the food from other seabirds.

These tactics have made these birds very successful as foragers. They hang around the breeding sites of birds such as gannets and terns waiting for a tired parent to return from the sea with a crop of food.

For the seabirds being targeted, these kleptoparasitic birds are just one more threat. The world’s 362 species of seabird can be found across every ocean and many islands. At sea, they prey on fish and squid. When they nest or rest on islands, their nutrient-rich guano shapes soil and plant communities, defining entire ecosystems.

But they are not doing well. Just under half of all seabird species (155) are now classified between “near threatened” and “critically endangered” on the world’s list of threatened species, the IUCN Red List. Of those with known trends, 56% have populations in decline.

The threats they face are daunting. Invasive predators such as mice and rats eat eggs or chicks on breeding islands. Many are caught by fishing boats as accidental bycatch, while overfishing depletes their prey. Then there’s climate change, habitat loss, and many other threats, including disease.

Seabirds are generally long-lived. They often raise only one chick every one or two years. Many species breed in only a few locations. They take many years to mature. Put together, these traits make recovery from population declines slow.

Of parasites and viruses

Three years ago, a more lethal strain of avian influenza virus emerged. This HPAI H5N1 2.3.4.4b strain has spread around the world, killing at least 280 million wild birds. The strain can also infect and kill marine mammals such as seals.

“HPAI” stands for Highly Pathogenic Avian Influenza, meaning the virus can more readily cause severe disease and death. The strain has become an animal pandemic (formally, a panzootic). It’s made it to Antarctica, but not yet to Australia or the rest of Oceania.

We know seabirds are particularly at risk. Our new research has shown kleptoparasites are at an even higher risk relative to other seabirds.

During the 2022 northern hemisphere summer, the virus killed roughly half of the world’s great skua (Stercorarius skua).

Food-stealing behaviour can enable the virus to spread. When a great skua harasses a gannet and makes it regurgitate food, the skua gets a fish meal – coated in saliva. If the gannet is infectious, its saliva will likely have a high viral load.

Once infected, these pirate birds can drive spread faster. Skuas, frigatebirds and gulls can cover great distances across polar regions and the tropics. They can transmit the disease to their mates, chicks, and other seabirds.

This means we could see outbreaks in new populations or places, hundreds or even thousands of kilometres apart. We have already seen signs of this in skua populations in the northern and southern hemispheres, with brown (Stercorarius antarcticus) and great skuas being some of the first detected H5N1 infections at new locations.

Skuas more often steal food from other seabirds when away from their breeding sites – including when they’re migrating back to these areas. If skuas get infected en route, they could bring the disease to their breeding sites and then beyond.

Frigatebirds are known for the red pouches on the necks of the males, which they inflate during breeding season. But they have other remarkable traits, such as travelling tens of thousands of kilometres across oceans outside breeding season. These travels are often broken up by “island-hopping”, where they will encounter and potentially infect other seabirds.

Frigatebirds and skuas have already suffered mass deaths from this strain of avian influenza.

While the virus is now almost everywhere, it hasn’t reached Australia, New Zealand, Oceania, and parts of Antarctica and the subantarctic. We can monitor skuas, frigatebirds and gulls for signs of illness to give us early warning that the virus has arrived.

By itself, avian influenza is a major threat to seabirds. But the outlook is even more dire when this is compounded with further human-caused threats. Identifying, managing, and reducing these threats is critical for their conservation, and the health of our islands and oceans.

Aotearoa New Zealand is a land of birds, from the smallest of wrens to the mightiest of moa. The ancestors of some species have been here for tens of millions of years, while others arrived only a few million years ago.

So a recent suggestion that moa and kiwi are recent immigrants from Australia, while wrens and kākāpō are New Zealand’s truly ancient birds, was sure to ignite controversy.

The contentious report was based on a scientific review of fossils found at St Bathans in Central Otago.

However, putting dates on arrivals requires a combination of both physical fossil evidence in deposits of a known age and genetic dating techniques that determine when the birds we know today diverged from their closest relatives.

Dating the arrival of birds in New Zealand

New Zealand is part of the larger continent of Zealandia, which finished separating from the supercontinent Gondwana some 57 million years ago.

Some familiar animals were likely present in proto-New Zealand at this time, including our unique silent frogs, the ancient tuatara and many invertebrates. Tens of millions of years of dispersal of both plants and animals followed.

Fossils and DNA allow us to explore these dispersal events in detail. Fossils can preserve evidence for millennia longer than DNA molecules, but DNA can shed light on many processes even when fossils are rare. This quality is particularly valuable since the chance of finding fossils decreases the further back we look in time.

Both approaches carry their own assumptions and biases that influence calculations of the range of arrival times.

Our team uses ancient DNA to date these arrivals, showing for example that the purple swamp hen ancestors of takahē and moho arrived in Aotearoa New Zealand around four million years ago from Australia, as part of a suite of open-habitat birds that included ancestors of the kakī black stilt, pouākai Haast’s eagle and kērangi Eyles’ harrier.

Other genetic studies have shown the ancestors of New Zealand wrens, the most primitive of all perching birds, split off about 50 to 60 million years ago. Wren fossils are part of the wonders unearthed at St Bathans, alongside remains of both moa and kiwi.

Genetic and morphological analyses of ratites (such as ostrich, kiwi, moa and elephant birds) suggest the ancestors of moa and kiwi reached Zealandia, separately, around 50 to 60 million years ago. Both groups filled the job vacancy in the ecosystem left by dinosaurs, becoming large and flightless.

The kākāpō, meanwhile, along with the kākā and kea, belong to a family that split off from all other living parrots very early on; they, too, are an ancient group. But genetic dating of their arrival in Zealandia remains unresolved, with studies variously putting it between 20 to 80 million years ago.

Precise dating of these splits presents a significant challenge. Nevertheless, the range between 30 million and a few million ascribed to the moa and kiwi by the recent announcement is not borne out by available evidence – and neither group is Australian as reported.

Moa are most closely related to the flying chicken-sized tinamous from South America, and kiwi are relatives of the giant extinct elephant birds from Madagascar. Indeed, Australia did not even exist as a discrete entity 50 to 60 million years ago; it was still firmly affixed to Antarctica and South America.

Exactly what routes the ancestors of moa and kiwi took to reach Zealandia remains unknown. They were part of a group of flying birds with a worldwide distribution called Lithornids, which lost flight many times independently and evolved into the ratites we know today.

The bones will speak

The St Bathans fossil deposit has given us an indispensable window into prehistoric New Zealand, and in many ways it is familiar – the bones of moa, kiwi, parrots, wrens and bats provide a reassuring continuity.

As the publication notes, though, there are also many strange things in the fossil deposit – crocodiles, a relative of flamingos and a giant turtle. There’s an Alice in Wonderland quality to St Bathans, and it’s a crucial piece of the story of Aotearoa New Zealand’s biological heritage.

The presence of a bird’s fossil in the deposit indicates the lineage was present in New Zealand a long time ago. But how long ago, exactly? Most estimates put the age of the St Bathans lake sediments between 12 and 20 million years, but these estimates are imprecise, making definitive statements about the age of animal groups difficult.

Even if a lineage was present in the St Bathans deposits, this still does not prove a continuous presence from that time to the present day.

Whatever the age of St Bathans, it’s tempting to think remains found in the palaeo-lake are members of truly ancient lineages, while things that only arrived after the lake dried up are invaders, little more than wayward tourists that got off at the wrong stop.

No matter when ancestors of birds arrived in New Zealand, their time on these isles has shaped their evolution in profound ways. Our team is working on determining arrival times and it’s looking increasingly dynamic, tied to environmental conditions.

The ancestors of the majestic huia arrived here 27 million years ago, evolving distinct beak shapes in males and females and white-tipped feathers that were high-status symbols in Māori society.

At the other end of the scale, the closest relative of the 16kg Haast’s eagle, whose ancestors arrived here a mere 2.5 million years ago, is the smallest eagle in the world – weighing only 1kg.

Let’s continue to embrace and care for our amazing bird fauna – whatever their age, they all have a bit of Aotearoa New Zealand in them.

For many Australians, the family home is their largest financial asset. With an increasing variety of ways to tap into home equity, the temptation to access this wealth is ever growing.

Homeowners increase the debt owed on their home when they borrow against their equity. Standard mortgage home loans now provide facilities for relatively cheap or free withdrawals of equity from the home.

This turns the home into an ATM, which borrowers can access when they choose.

Our new study asks what motivates Australians to tap into their home equity, and how does this behaviour change with age?

Surprisingly, despite having much lower housing equity levels, younger homeowners borrow often, and borrow more, than their Boomer parents.

How common is equity borrowing?

Using 15 years of data from the government-funded Household, Income and Labour Dynamics in Australia (HILDA) survey, we tracked the mortgage debt and repayments of homeowners aged 35 and over.

The chart below shows younger owners are far more likely to engage in equity borrowing.

In 2006, nearly 39% of the youngest homeowners, aged 35–44, borrowed against their home equity. By 2021, this number had dropped to 29%. Despite the decline, it’s still 24 percentage points more common than those aged 65 and over. The older group has remained steady at about 5% over the years.

How much do equity borrowers withdraw from their home?

Among those who use their home like an ATM, younger borrowers now withdraw larger amounts than older borrowers.

In 2006–07, equity borrowers aged 35–44 and 45–54 withdrew on average $43,000 and $57,000, respectively (expressed in real values set at 2022 price levels). By 2021, the amount withdrawn by these two age groups had climbed to $70,000 and $100,000.

On the other hand, the amount withdrawn by borrowers aged 55 or older fell from more than $50,000 to less than $40,000.

What motivates equity borrowing?

Young homeowners’ equity borrowing behaviours are sensitive to changes in house prices and debt values, and their financial risk preferences. Among those aged 35–44, a $10,000 increase in the primary home value raises the likelihood of equity borrowing by ten percentage points.

Every $10,000 in debt against the primary home reduces the likelihood by 2.8% percentage points. Those willing to take substantial financial risk are eight percentage points more likely to borrow against their home than those who are risk-averse.

Those aged 65+ are not inclined to borrow, and exhibit little change in equity borrowing behaviour with variations in asset, debt, income or financial risk preferences.

Why borrowing practices differ between age groups

As well as being more likely than older homeowners to borrow against equity, the younger group also withdraws higher amounts than their Boomer parents.

This is despite younger borrowers already carrying much higher debt against their primary home. Among those in our study who engaged in equity borrowing in 2021, the median debt before borrowing was $401,000 for 35-44 year-olds compared to $0 for those aged 65+.

As real house prices have risen over decades, the current generation of young homeowners has had to invest more money into purchasing their first home than previous generations.

It’s therefore not surprising the primary home is now widely viewed as a financial resource to be tapped into to meet spending needs.

On the other hand, most Baby Boomers bought their first home at more affordable prices than their children, and at lower levels of debt. Now they don’t appear to be spending their kids’ inheritance by drawing down housing wealth.

In fact, older parents may shy away from equity borrowing to bequeath wealth to children. Some also dislike passing debt on to their children.

Older people may also avoid equity borrowing due to concerns about aged care costs. Some may be hampered by poor financial literacy.

More debt ahead without policy changes

Present trends suggest young homeowners will remain indebted for longer periods, and more and more will retire with mortgage debt.

For indebted retirees, there are real prospects of drawing down of superannuation to pay off mortgages in retirement.

This may impose extra burdens on the age pension system. Another unwelcome consequence, which may add to health costs, is the prospect of debt-related psychological distress among those who can’t pay off their mortgage in old age.

If the current trends continue, the great wealth transfer that has already begun looks set to further entrench inequality between those who have access to the bank of mum and dad and those who do not.

Encouraging older people to use their housing equity to fund their needs in old age may lighten fiscal burdens on younger generations. But policy reforms will be needed to relieve concerns about the risks of equity borrowing in old age.

The federal government is stepping up its fight against scams, which last year cost Australians more than A$2.7 billion.

On Friday, the federal treasury released a draft scam prevention framework. The government said the plan is:

an economy‑wide reform to protect the Australian community from scams. It takes a whole‑of‑ecosystem approach to reduce gaps which scammers can exploit.

Many of the measures it includes are designed to put more responsibility onto social media companies, banks and telecommunications companies. This is a welcome move which favours the victims of scams.

However, the increasing sophistication of scams using artificial intelligence (AI) technologies presents an ongoing challenge. The framework also needs to be broader in scope if it is to achieve its aim.

A popular target for scammers

A scam is a criminal scheme designed to deceive someone and steal their personal information and money.

Australia is a popular target for cyber criminals from all around the world. In 2023, there were more than 600,000 scam reports in Australia. This was an 18.5% increase from the previous year.

In total, these scams cost Australians more than A$2.7 billion.

However, this figure is only from reported scams. There are certainly many more unreported ones, too.

Worryingly, new technology is being weaponised by scammers. Recent advances in AI and deepfakes will continue to bring newer variants of scams.

A focus on organisations, not victims

The proposed scam prevention framework in Australia seeks to encourage organisations to stop scams before they happen.

The framework applies to banks, social media platforms and telecommunication companies and requires them to identify, filter and stop scam-related content and transactions.

For example, search engines and social media platforms would be required to authenticate and verify the identity of business users and advertisers. This is aimed at preventing the proliferation of scam advertisements and scam accounts.

Companies that fail to prevent scams would incur a maximum A$50 million penalty.

The proposed framework doesn’t include a requirement for banks to reimburse scam victims. However, the framework imposes a transparent dispute resolution system.

Even before announcing the new anti-scam framework, the federal government was emphasising the importance of cyber security.

This government was the first in the country’s history to introduce a minister for the cyber security portfolio (a position currently held by Tony Burke). It has also launched initiatives such as the $58 million National Anti-Scam Centre.

Other jurisdictions have also been upping their efforts to tackle the problem of scammers. For example, in the United Kingdom banks are supposed to refund scam victims. However, recent changes will favour banks by reducing the maximum reimbursement amount from £415,000 to £80,000 (A$812,000 to A$156,000).

Will it work?

The A$50 million penalty will force banks, telcos and social media companies to improve their scam-fighting tactics, techniques and procedures.

However, in the event of a scam, just blaming these three types of organisations without a transparent investigation will not necessarily help scam victims. Instead, it may just become a courtroom drama in which government prosecutors and corporate lawyers battle it out over whether a fine should be imposed.

It is important to focus on the entire ecosystem of scams. Most start by criminals accessing the contact details of a person, such as their mobile phone number.

Text message-based scams were the most reported in 2023 and scam calls resulted in the highest reported losses of all scams (A$116 million).

Criminals get access to mobile phone numbers in several ways. The most common methods include the dark web, automatic random number generators and simple Google searches.

For example, well-respected members of the community who provide voluntary services – such as Justices of the Peace – have their mobile numbers publicly accessible. Some of these people are senior citizens who are often targeted by scammers.

It’s also possible for scammers to access personal data shared with and stored by various companies in today’s digital economy. So, we cannot just say it is always the responsibility of a bank, social media platform or telco to fight scams.

Instead, we need to look at the entire end-to-end pipeline of scams – and hold everyone who is a part of that accountable.

Immediate steps

The federal government’s draft scam prevention framework is open for public consultation for the next three weeks. In the meantime, there are steps people can take now to ensure they are better protected against scammers.

Above everything, be very careful with sharing your personal contact details, such as your phone number or email address. You can also access many resources which will help you be prepared and avoid becoming a scam victim. They include the following quizzes:

• the Australian Signals Directorate helps people get better at spotting scams
• Consumers Affairs Victoria offers to check scam savviness
• the ABC helps people differentiate between scam and legitimate information
• the Special Broadcasting Service News helps people outsmart the scammers .

Health at every size (or HAES) is a lifestyle counselling approach that promotes mindful eating and lifestyle behaviours to pursue health and wellness, without focusing on weight loss. Weight loss is seen as a beneficial side effect, rather than a goal.

The Association for Size Diversity and Health first developed the approach in 2003 and revised it in 2013 and 2024. Its current core principles promote:

• minimising weight discrimination
• encouraging body acceptance
• intuitive eating
• enjoyable physical activities.

It also aims to address stigma and discrimination that people in larger bodies may experience when seeking medical care.

Internationally, a range of health professionals have incorporated the HAES approach into their treatment and services. Some organisations, such as Obesity Canada, have included HAES in their guidelines for obesity treatment.

How does it compare with weight-focused treatments?

We conducted a systematic review and meta-analysis of all the research studies published until November 2022 that had used HAES-based programs.

Across 19 scientific papers, we compared the outcomes of people living in larger bodies who used HAES-based programs with:

• conventional weight loss programs (six studies)
• people on waiting lists receiving no treatment at all (six studies)
• groups where people received weekly social support in groups (four studies).

We evaluated the program’s impact on appetite, weight, physical health measurements including cholesterol and blood pressure, and also wellbeing and mental health.

Our analysis found HAES interventions were beneficial in reducing susceptibility to hunger more than other approaches, meaning people had less subjective perceptions of hunger or eating in response to emotions.

However, compared to control interventions, HAES did not show superior results for improving any other physical health outcome – weight loss, blood cholesterol levels, blood pressure – or wellbeing or mental health outcomes.

Given the results to date, the choice about whether to use a HAES-based approach (or not) will depend on each person’s preference, needs and goals.

Don’t get your health advice from influencers

While HAES has been used in clinical practice for many years, some United States and Canadian anti-diet practitioner’s motives have been scrutinised because of their links with processed food companies.

The spotlight was put on the very small number of dietitian “influencers” (roughly 20 from a membership of more than 80,000 dietitians in the US and Canada) promoting “eat what you feel like” and discouraging people from making weight loss attempts, under the banner of HAES. They failed to mention they were being paid to promote products sold by food, beverage or supplement companies.

US author and dietitian Carrie Dennet urges people to not look to influencers for health advice. Instead, seek non-judgemental health care from your GP.

What might treatment look like?

When improving your health is a treatment goal, a good place to start your journey is to have a health check-up with your doctor, as well as to assess your relationship with food.

A healthy relationship with food means being able to eat appropriate amounts and variety of foods to meet your nutritional, health and wellbeing goals. This might include strategies such as:

• keeping a food mood diary
• reflecting on factors that influence your eating
• practising mindful eating
• learning about nutrient needs
• focusing on food enjoyment and the pleasure that comes from preparing, sharing and eating with others.

If you need more help to develop this, ask your doctor to refer you to a health practitioner who can assist.

What if your goal is weight loss?

When it comes to medical nutrition therapy to treat weight-related health conditions, such as high blood pressure and type 2 diabetes, the approach will depend on individual needs and expectations.

Broadly, there are three graded energy intake target levels:

1. a reduced-energy diet where the goal is to lower energy intake by 2,000 to 4,000 kilojoules (kJ) per day by identifying food substitutions, like swapping soft drinks and other sugar-sweetened drinks for zero or diet versions or water.

2. a low-energy diet, which uses an energy intake goal in the range of 4,200-5,000 kJ, up to 7,000 kJ per day depending on an individual’s energy expenditure.

3. the most restricted regime is a very low-energy diet, has an energy intake target less than 2,500 kJ/day, achieved using formulated meal replacement products.

The aim of a very low-energy diet is to facilitate rapid weight loss when this is essential to improve health acutely such as poorly controlled type 2 diabetes. Such a diet should be used under supervision by your doctor and dietitian.

When selecting an initial strategy, seek a balance between energy intake goals and your ability to stick to it. Your approach may change over time as your health needs change.

If you need personalised nutrition advice, ask for a referral to an accredited practising dietitian. The register of service providers though Dietitians Australia allows you to view their expertise and location.

Regardless of whether your practitioner uses a HAES approach or not, your health providers should always treat you with respect and address your personal health and wellbeing.

The destruction of nature is a global crisis. Establishing protected areas of forest is a common policy governments use to tackle the problem.

Indeed most countries, including Australia, have signed a global agreement to protect 30% of land by 2030. But to what extent do protected areas, such as national parks and nature reserves, actually preserve forests?

My new research examined this question. The findings are the first global-scale estimate of where protected areas are succeeding and failing.

Alarmingly, I found protected areas fail to prevent forest loss in many parts of the world. Clearly, we must make these areas more effective to conserve the remaining diversity of Earth’s plants and animals.

Probing protected areas

Forests are often destroyed through human activity such as logging with chainsaws or the deliberate use of fire. The aim is usually to extract timber, or to clear land for agriculture, roads, housing or other human purposes.

Natural bushfires can also damage forests. In some cases, ecosystems are so badly burnt they cannot recover. There’s a link to human activity here too, because human-caused climate change is leading to more severe, frequent, and wider-ranging bushfires in places such as Australia.

I wanted to know how well protected areas prevent forests from being lost.

To work this out, I first took a map that covers the precise boundaries of about 300,000 of the world’s protected areas. I overlaid it with high-resolution satellite data from between 2001 and 2022 showing forest loss just inside and just outside these boundaries.

This method assumed if forest loss was much higher just outside the boundary of a protected area than inside, the protection was working.

Conversely, if forest loss was relatively similar inside and outside the boundary, that shows the protection did not have a strong effect.

This idea can apply even if forest loss on both sides of the boundary is low – because it suggests the area is remote or otherwise not sought-after for human activity. In these cases, we have no evidence that protection is effective, because the forest probably would have been retained even if the protection wasn’t in place.

What I found

I found protected areas prevent an average 30% of forest loss that would have occurred if the policy was not in place. Forest loss occurred in protected areas in all countries – including Australia – but less frequently than in unprotected forest.

The 30% figure is discouragingly low. But it does indicate protected areas are effective to some degree. And effectiveness varies significantly across countries, as the below graphic shows.

The policy is almost completely ineffective in many countries, including Indonesia, the Democratic Republic of the Congo, Bolivia, Venezuela, Madagascar, Russia and Gabon. Several of these countries house vast amounts of the planet’s remaining biodiversity. Most, but not all, are developing economies.

In the case of forest loss due to fire, protected areas in advanced economies were also ineffective in some cases.

Australia is a good example. Protected areas here were fairly effective from 2001 to 2018. But the horrific 2019–20 Black Summer fires burned indiscriminately through large swathes of protected forest.

In better news, protected areas were highly effective in some areas, such as New Zealand, Canada, Scandinavia and the Baltic states (Estonia, Latvia and Lithuania).

What this all means

My research illustrates the large improvements needed in many protected areas across the globe to genuinely conserve forests. More research is also needed to understand the best policies to achieve this, before it’s too late.

Developing countries clearly need help to protect their forests. Corruption, political instability, and a lack of resources can make it difficult for governments in these nations to enforce forest conservation laws. Government indifference can also play a role.

How do we turn this around? Schemes such as REDD+, which pays local communities to conserve forest that may otherwise be cleared, could be scaled up.

Foreign aid for forest conservation, from countries such as Australia, can also help. And non-government organisations such as African Parks can put rangers on the ground to help patrol and enforce the integrity of protected areas.

Technology such as real-time deforestation alerts from satellite data can also help.

My findings also highlight the threat climate change poses to forest ecosystems in Australia and elsewhere. Obviously, fire does not respect the boundaries of a national park or other protected area.

So yes, it’s great to see governments around the world signing up to protect 30% of their land. But my work shows attention is needed to make sure those protected areas are working.

Christopher Wheeldon and The Australian Ballet’s Oscar, which had its world premiere in Melbourne on September 13, is based on the story of Oscar Wilde: the writer, the man, the protester.

Combining key life events with two of Wilde’s well-known works – The Nightingale and the Rose, and The Picture of Dorian Gray – Wheeldon has created a complex and highly cinematic ballet about a literary genius who was also a gay martyr.

Wheeldon has also delivered on something I think has been long overdue: a gay ballet.

Act one: memories of happier days

The first act begins with Wilde’s trial and conviction for committing sexual acts with men.

From his prison bed, we see the memories of love that flood his mind. We see him happy with his wife Constance and their children, and attending literary and social occasions. We see memories of his favourite female actors, as well as his introduction to his best friend Robbie Ross and the secret world of gay men.

These stories are segmented; the scenes cut from one to another, as well as to the unfolding tale of Wilde’s nightingale and her futile sacrifice and death for love.

These are the mixed-up memories of a man facing the horrific consequences of standing up for a forbidden love. In them we see a world where Wilde was successful and happy. In his iconic suit and waistcoat, he is the Oscar Wilde we know.

But this is a man only beginning his prison time.

Act two: the horror sinks in

In the second act we see Wilde deep into his two-year sentence, lying on the floor of his cell. Isolation, malnutrition and hard labour have destroyed him both physically and emotionally. He is remembering his relationship with Lord Alfred Douglas that ultimately led to his conviction and imprisonment.

Again, the scenes are cut and interspersed with other scenes from the trial, of his family, his friend Ross and the nightingale. They are also set next to pieces of the story of Dorian Gray, in which Wilde and Douglas at times replace Dorian the man and Dorian the decaying portrait.

In act two, Wilde is a broken man. The memory scenes are seedier, darker, and more debauched and threatening. Sex largely replaces the romantic and platonic love of the first act. We see dimly lit illegal gay sex scenes and cavorting in cabaret clubs. Wilde stumbles through the act in his dirty dark green prison uniform.

An ‘out’ ballet

Wheeldon and The Australian Ballet artistic director David Hallberg have described Oscar as the first “out” gay ballet.

In act one, a near-kiss prepared us for what was to come in act two, two men kissing on the ballet stage. In the program, Wheeldon states both he and Hallberg, as gay men, felt a gay ballet narrative was overdue and that the time was right to make one.

But what makes Oscar a gay ballet? Is it the heroic narrative about an historic gay figure? Is it two men kissing for perhaps the first time on an Australian ballet stage? Is it because it is made by gay men who themselves have called it a gay ballet?

Yes, it’s all of these. But it’s also more than that.

As Hannah McCann and Whitney Monaghan suggest in their book Queer Theory Now, the term “queer” is used to describe not just the slipperiness of categories and boundaries of gender and sexuality, but also of more general categories and boundaries.

In Oscar, there is a slipperiness of the category of ballet. The movement vocabulary in the ballet draws from multiple forms of dance. Music theatre, for instance, has a strong presence in one courtroom scene in which chairs and benches are being manoeuvred in formations.

There is classical ballet, such as with the pas de deux between Oscar and his wife. There are contemporary lyrical pieces, including Ross’s solo which opens the second act. There is a touch of Russian constructivism with geometric arm shapes, mechanised jerky movement and fixed mask-like facial expressions.

There is even a little vaudeville, with cancan and cross-dressing – as well as some sassy Balanchine-esque moments of contemporary ballet with slides and swings, strong geometries and slightly cocked hips.

This melange applies equally to Joby Talbot’s score. It moves from classical, to jazzed up, to recorded sounds, to techno.

Jean-Marc Puissant’s costumes also follow the trend. While traditional rich Victorian clothes are worn in the historical scenes, the costumes in the nightingale story are brightly coloured and flamboyant, some with Wilde’s handwriting printed into the fabric. Wilde’s simple prison uniform is much like pyjamas.

Oscar is a pastiche of forms of dance, music and design unapologetically and abruptly juxtaposed across a splintered narrative that cuts like a piece of cinema from one scene to the next. It is Swan Lake meets Baz Luhrmann, Moulin Rouge meets the Brothers Grimm.

At the start of opening night, Hallberg warned the audience they might be shocked. Perhaps some were, but the standing ovation at the end suggested this was a much-loved and welcomed ballet.

Oscar is showing at the Regent Theatre, Melbourne, until September 24 and at the Sydney Opera House from November 8 to 23.

Donald Trump inherited a strong economy from President Obama and managed it poorly.

Real GDP grew more slowly under Trump than it had under any president since the second world war. He was the only president since then to preside over a fall in the number of workers with a job.

In 2016, the United States (US) economy was the world’s largest; by 2020 China’s was more than 10% bigger.

Trump’s economic policies

Would a second Trump presidency be any better? Hopefully, there will not be another pandemic for him to mismanage. But his policies suggest the economy would again do poorly.

Admittedly, it is hard to be sure about the policies Trump would adopt in a second term as his record of implementing his promises is so poor. Mexico never paid for a border wall. Hillary Clinton was not locked up. And I doubt many Americans were “tired of winning”.

The provision of policy detail has not been a defining feature of Trump’s rallies. There is a lot of detail in the 900 pages of Project 2025, produced by right-wing think tank the Heritage Foundation and whose writers include many former Trump advisors.

But Trump has disowned it. On his social media site he said both that “I disagree with some of the things they’re saying” and “I know nothing about Project 2025”.

Trump and Elon Musk

In businessman and investor Elon Musk’s rambling conversation with him on X, Trump had little to say about economics beyond not taxing tips. The moderators in the debate with Harris did try to elucidate more about his economic plans but it was a struggle.

To Musk, Trump claimed there is a “disaster with inflation”, which he falsely claimed was the worst in a century. In his debate with Harris, he was even more inaccurate calling it “probably the worst in our nation’s history, we were at 21%”.

Actually inflation had been higher in the 1970s than the peak of 8% under Biden. Inflation is now down to 2.5%.

He promised to end inflation quickly, but did not say how. He claimed a “drill, baby, drill” policy would cut petrol prices, an odd priority when talking to an electric car maker. And this would take years to have any impact.

In the debate he claimed he would “cut taxes very substantially”. Which taxes, he did not say, but his record suggests it would be taxes on the rich. Nor did he say what spending he would cut to fund the tax cuts, or whether he would just allow the government debt to expand further.

He has threatened the independence of the Federal Reserve, which could lead to interest rates being higher as expectations of inflation rise.

Policies or ‘concepts’?

Eight years after he campaigned for president criticising Obama’s health care arrangements, all Trump could offer as an alternative at the debate was “concepts of a plan”.

The clearest policy he has announced is more tariffs. He has proposed an across-the-board tariff of 10%, or perhaps 20%. For China they would be 60% or more.

The clear result would be American households paying much more for basic goods. Many goods US households buy are imported and US manufacturers import raw materials and components for the goods they make and machinery to make them.

It is likely many countries on which Trump imposes these tariffs will retaliate, making it harder for US exporters.

IMF modelling estimated the impact of Trump’s previous trade policies was to cut US (and global) GDP by around half to 1%. But now he is proposing much higher tariffs.

US and trade deficits

Trump is almost as fixated about the size of trade deficits as he is about the size of crowds at his rallies. But in his term as president, notwithstanding his tariffs, the US trade deficit was not narrowed.

Another way Trump would damage US trading interests is his impact on their “soft power”. He is very unpopular in many countries. A Trump-led US would likely attract fewer tourists and international students.

A bizarre new Trump policy is to create a “national bitcoin stockpile”. Following the lead of El Salvador’s self-described dictator Nayib Bukele, Trump would gamble taxpayers’ money on a hoard of speculative tokens which he had formerly called out as a “scam”.

As the world’s second largest economy, and a major customer of the rest of the world, a protectionist and smaller US economy would be a drag on global economic growth. There would be lower wages and fewer jobs globally as a result.

The big concern

But the major longer-term impact of a second Trump presidency on the global economy would come from his rejection of climate change.

He has called climate change a hoax. Asked directly about climate action in the first 2024 debate, Trump just referred irrelevantly to clean water. There was no mention of any action to reduce greenhouse gas emissions.

He would, again, withdraw the US from the Paris climate accords. This would be a major setback to attempts to moderate the increase in greenhouse gas emissions. As the second largest emitter, the US would directly contribute to a hotter planet and more deaths.

Unapologetically sentimental, uncynically joyful, and brimming with wholeheartedness, Love Stories delivers exactly what its title promises.

Adapted by Tim McGarry from Trent Dalton’s 2021 book and directed by Sam Strong, this production is an uplifting celebration of love in all its forms.

Sitting on a street corner in Brisbane with a typewriter, an author (identified as “Husband” in the program) solicits love stories from passers-by. An exuberant and kaleidoscopic series of vignettes follows, based on (and some recounted verbatim from) stories told by real people.

A man proposes to his girlfriend via flash mob; grandparents describe their love for their grandchildren; a woman reconnects with her heroin-addicted mother; a widow grieves the loss of her husband. Interwoven through these narratives is the Husband’s own love story with his wife.

Inspired by the real-life marriage of Dalton and Fiona Franzmann, this story explores the underbelly of work, pain and hard-earned joy that sits beneath a seemingly perfect relationship.

Powerfully moving

Two hours of love stories could easily become emotionally repetitive or stale. However, McGarry, Dalton, Franzmann and Strong have deftly crafted a narrative arc that balances light and shade, joy and sorrow, renewal and loss.

The vignettes are, without exception, engaging, heartwarming, funny and, at times, powerfully moving. Although varied, they are held together by the spinal narrative thread of Husband and Wife.

Jason Klarwein and Michala Banas shine in their portrayals of Husband and Wife, bringing a down-to-earth warmth and relatability to their depiction of a loving marriage under strain. They are supported by a strong ensemble, who move seamlessly between characters and storylines, often with impressive clarity. Bryan Probets’ and Jeanette Cronin’s playful and at times hilarious transformations are particularly enjoyable.

Throughout the production, on-stage cameras capture and project footage of the actors onto a screen at the back of the stage. Craig Wilkinson’s video design and Tnee Dyer’s camera work are tightly choreographed and often strikingly beautiful.

The projections are at their best in the moments of cinematic intimacy, when close-ups of characters’ faces allow the audience to see every nuance of their pain and joy.

Occasionally, the simultaneous on-stage action and video feed becomes overwhelming, with the two elements distracting from rather than supporting each other. For the most part, however, the camera work adds intimacy and texture to the drama.

Joyful and explosive celebration of love

This production, according to Dalton’s program note, aims not only to celebrate love, but also to ask the deeper question: what is love?

Many of its stories suggest answers, as well as raising their own questions. Is it more loving to hold onto someone or let them go? Where is the line between worthwhile effort and unreasonable sacrifice?

While these are rich and important questions, they are not always given space to settle and expand. The sheer number of stories packed into this nearly two-hour production means the action is at times almost frenetically busy. The pace is engaging and exciting – but leaves little time for deeper explorations of each story’s questions and themes.

This production may not always reach the philosophical depths it seems sometimes to aim at, but this does not detract from the joyful and explosive celebration of love that is its greatest achievement.

Some of the play’s most powerful moments are generated the moments when the production leans into a well-earned stillness and thoughtfulness.

A stunning monologue on the continuity of love across thousands of First Nations generations is performed beautifully by Mathew Cooper. An ordinary conversation between Husband and Wife reveals how a seed of discord can be sown while you’re brushing your teeth for bed. The story of Sakura Tomii, performed movingly by Kimie Tsukakoshi, reveals the depths of pain that can live behind a cheerful smile from a stranger.

Love Stories is peppered with quotations and expressions of love. “Love is all there is,” quotes a passing poet. “Love is the answer to every question”, Wife tells her Husband. “I love you”, signs a young girl to her boyfriend across a busy street.

In the final moments, the character Jean-Benoit – a busker who has acted as a chorus of sorts, played engagingly by Rashidi Edward – invites the audience to go out into the world and love one another. There is no subtlety here: love more, love better and love deeply is the resounding battle cry of this production.

A cynic might raise an eyebrow, but who wants to be a cynic? More than anything else, Love Stories is an expression of hope. Love does exist: people live, strive and make sacrifices for one another every day.

It is an undeniably important reminder, and it is delivered with joy, energy, humour, passion and beauty.

Love Stories is playing at QPAC for Brisbane Festival until September 29.

The rings of Saturn are some of the most famous and spectacular objects in the Solar System. Earth may once have had something similar.

In a paper published last week in Earth & Planetary Science Letters, my colleagues and I present evidence that Earth may have had a ring.

The existence of such a ring, forming around 466 million years ago and persisting for a few tens of millions of years, could explain several puzzles in our planet’s past.

The case for a ringed Earth

Around 466 million years ago, a lot of meteorites started hitting Earth. We know this because many impact craters formed in a geologically brief period.

In the same period we also find deposits of limestone across Europe, Russia and China containing very high levels of debris from a certain type of meteorite. The meteorite debris in these sedimentary rocks show signs that they were exposed to space radiation for much less time than we see in meteorites that fall today.

Many tsunamis also occurred at this time, as can be seen from other unusual jumbled up sedimentary rocks.

We think all these features are likely related to one another. But what links them together?

A pattern of craters

We know of 21 meteorite impact craters that formed during this high-impact period. We wanted to see if there was a pattern in their locations.

Using models of how Earth’s tectonic plates moved in the past, we mapped out where all these craters were when they first formed. We found all of the craters are on continents that were close to the equator in this period, and none are in places that were closer to the poles.

So all the impacts occurred close to the equator. But is this actually a fair sample of the impacts that occurred?

Well, we measured how much of Earth’s land surface suitable for preserving a crater was near the equator at that time. Only about 30% of the suitable land was close to the equator, with 70% at higher latitudes.

Under normal circumstances, asteroids hitting Earth can hit at any latitude, at random, as we see in craters on the Moon, Mars and Mercury.

So it’s extremely unlikely that all 21 craters from this period would form close to the equator if they were unrelated to one another. We would expect to see many other craters at higher latitudes as well.

We think the best explanation for all this evidence is that a large asteroid broke up during a close encounter with Earth. Over several tens of millions of years, the asteroid’s debris rained down onto Earth, creating the pattern of craters, sediments and tsunamis we describe above.

How rings form

You may know that Saturn isn’t the only planet with rings. Jupiter, Neptune and Uranus have less obvious rings, too. Some scientists have even suggested that Phobos and Deimos, the small moons of Mars, may be remnants of an ancient ring.

So we know a lot about how rings form. Here’s how it works.

When a small body (like an asteroid) passes close to a large body (like a planet), it gets stretched by gravity. If it gets close enough (inside a distance called the Roche limit), the small body will break apart into lots of tiny pieces and a small number of bigger pieces.

All those fragments will be jostled around and gradually evolved into a debris ring orbiting the equator of the larger body. Over time, the material in the ring will fall down to the larger body, where the larger pieces will form impact craters. These craters will be located close to the equator.

So if Earth destroyed and captured a passing asteroid around 466 million years ago, it would explain the anomalous locations of the impact craters, the meteorite debris in sedimentary rocks, craters and tsunamis, and the meteorites’ relatively brief exposure to space radiation.

A giant sunshade?

Back then, the continents were in different positions due to continental drift. Much of North America, Europe and Australia were close to the equator, whereas Africa and South America were at higher southern latitudes.

The ring would have been around the equator. And since Earth’s axis is tilted relative to its orbit around the Sun, the ring would have shaded parts of Earth’s surface.

This shading in turn might have caused global cooling, as less sunlight reached the planet’s surface.

This brings us to another interesting puzzle. Around 465 million years ago, our planet began cooling dramatically. By 445 million years ago it was in the Hirnantian Ice Age, the coldest period in the past half a billion years.

Was a ring shading Earth responsible for this extreme cooling? The next step in our scientific sleuthing is to make mathematical models of how asteroids break up and disperse, and how the resulting ring evolves over time. This will set the scene for climate modelling that explores how much cooling could be imposed by such a ring.

Australia has debated and studied high-speed rail for four decades. The High Speed Rail Authority has begun work on a project that could finally deliver some high-speed rail in the 2030s.

The Albanese government set up the authority in 2022. It also committed A$500 million to plan and protect a high-speed rail corridor between Sydney and Newcastle. This corridor was prioritised due to significant capacity constraints on the existing line, among other reasons.

The ultimate plan is for a high-speed rail network to connect Brisbane, Sydney, Canberra, Melbourne and regional communities across the east coast. The network would help Australia in its urgent task to reduce greenhouse gas emissions from transport. These continue to increase even as emissions from other sectors fall.

The authority has now publicly outlined plans for the first stage of this east coast network. After a history of failed proposals dating back to 1984, the new plans provide some cause for optimism that Australia could have some high-speed rail by 2037.

What is high-speed rail and why do we need it?

The International Rail Union of Railways defines high-speed rail as new lines designed for speeds of 250km/h or more and upgraded lines for speeds of at least 200km/h.

High-speed rail could greatly reduce transport emissions by replacing air travel in particular.

For example, the 7.92 million passengers flying between Melbourne and Sydney in 2023-24 produced about 1.5 million tonnes of emissions. Including travel to and from airports and other flight routes along the corridor (Sydney or Melbourne to Canberra, Albury etc), this adds up to about 2% of annual domestic transport emissions.

A Sydney–Melbourne high-speed rail link could cut emissions to a fraction of those from air and road transport. If Australia is to achieve net zero by 2050, a shift to rail will be essential.

High-speed city-to-city rail services will be needed to become an attractive alternative to air travel.

What is the authority working on?

Early this year the High Speed Rail Authority gained a new CEO, Tim Parker, with extensive experience in delivering mega-projects. In late August, the authority outlined its plans at an industry briefing in Newcastle.

The authority has commissioned eight studies, including a business case for a Sydney–Newcastle line. Significantly, it will include the cost of future highway upgrades if high-speed rail does not proceed. This study, along with a report on how high-speed rail will proceed along Australia’s east coast, is due by the end of this year.

Also under way is a geotechnical study that includes drilling 27 boreholes. It will help determine the proposed depths of two long rail tunnels and guide decisions on crossing the Hawkesbury River and the route to the Central Coast and on to Newcastle.

All going well, including land acquisition and agreements with the New South Wales government (which could include funding), work could start in 2027 and be completed by 2037.

Many questions remain

Given the time and money required to deliver a Sydney–Newcastle line, bipartisan support will be needed. However, the federal opposition is yet to make a clear commitment to high-speed rail.

There are other uncertainties too. Will the trains be operated by the public or private sector? The latter was the intention for projects that were scrapped decades ago, such as the CSIRO-proposed Very Fast Train (VFT) linking Sydney, Canberra and Melbourne, and the Sydney–Canberra Speedrail.

And how will the engineering projects be delivered? The new authority must learn from the project management problems in delivering the Inland Rail freight line. The project is running late and costs have blown out.

Some major federally funded government projects have worked well. These include upgrades of the national highway system (by state road authorities and contractors) and the new Western Sydney International Airport, which is nearing completion.

And what about a full Sydney–Melbourne line?

The big question is when work will start on a Sydney–Melbourne high-speed rail service. In 2019, International High-Speed Rail Association chairman Masafumi Shukuri estimated building this line could take 20 years.

The present line is 60km longer than it should be as the route dates back to the steam age. It also has far too many tight curves. This means train travel on this line is slower than cars and trucks.

As former NSW State Rail chief Len Harper said in 1995, this railway was already “inadequate for current and future needs” even back then.

When the VFT was proposed in 1984, questions were raised as to whether our population was big enough for such a project. Now, more than 15.5 million people live in NSW, Victoria and the Australian Capital Territory. Melbourne–Sydney is the world’s fifth-busiest flight route.

Advocacy group Fastrack Australia has called for a Sydney–Melbourne track built to high-speed standards and able to carry freight. The estimated travel time is four hours.

This group and the Rail Futures Institute propose the line be built in stages, with priority given to the section from near Macarthur to Mittagong in NSW. This would reduce the current line’s length by about 18km and allow for better Sydney–Canberra train services.

Urgent action is needed to protect the rail corridor from encroaching urban development.

Australia needs to catch up

In June 2023, when the new authority started work, I observed that Australia must surely hold the world record for studies into high-speed rail with no construction.

In stark contrast, this October marks the 60th anniversary of the world’s first dedicated high-speed rail line, the Tokaido Shinkansen in Japan linking Tokyo to Shin-Osaka. The network has since grown in stages to about 3,000km of lines.

Today, high-speed rail operates in 21 countries over about 60,000km of lines – China has about 40,000km. Indonesia’s high-speed rail service between Jakarta and Bandung started running last year. India and Thailand are in the advanced stages of delivering high-speed rail. It’s also under construction in another 11 countries.

Australia could finally join them in the next few years if it starts building the Sydney–Newcastle line.

New Zealad’s current electricity supply crisis requires immediate solutions.

But we argue the government’s emphasis on importing natural gas and construction of centralised solar farms is a missed opportunity.

The case against gas has been highly publicised because of its greenhouse gas emissions and substantial costs.

But the government’s focus on large solar infrastructure in rural areas, away from our main centres, misses a chance to address two urgent issues at once – the need to cut emissions and to adapt to climate impacts.

Instead, we should plan local renewable energy generation, integrated into communities, to improve New Zealand’s energy security and disaster preparedness.

Centralised versus decentralised energy systems

Centralised renewable electricity generation using large-scale hydro, wind and solar infrastructure helps to cut emissions and move New Zealand closer towards a fully renewable grid. These projects can be implemented quickly and are a positive step.

However, we must also focus on climate change adaptation. Creating more renewable electricity alone won’t help during power outages, which might become more frequent due to climate-related extreme weather events.

During Cyclone Gabrielle in 2023, almost 234,000 homes lost power, some for over a week.

Solar technologies offer opportunities to distribute electricity generation and storage by integrating power into buildings and cities. Bringing electricity generation close to where it is used helps to increase resilience during extreme weather events and other disruptions to power lines, including earthquakes.

Although large solar farms generate clean electricity at scale, they keep generation far away from where it is used. This applies new technologies in an old-fashioned way, centralising power generation in a few locations, controlled by a handful of companies.

Government policies and incentives could help to integrate solar generation into communities to create resilient places, with access to their own power during natural disasters and outages.

For instance, integrating solar panels into schools, public buildings, hospitals and homes would enhance resilience, especially for our most vulnerable populations.

While there are already some projects of this type through the New Zealand Solar Schools Project and Community Renewable Energy Fund, much more could be done. Instead of using productive farmland distant from communities, we could better utilise the many rooftops and walls available in cities.

Even though solar power’s peak generation around midday does not align with peak electricity demand in New Zealand, every small solar system connected to the grid contributes. At the national scale, the water flowing into hydro lakes could be held back in the dams to meet evening peaks in demand when solar is no longer available.

SolarZero’s virtual power plant, made up of thousands of home batteries, is already helping New Zealand get through cold snaps by feeding electricity to the grid. Photovoltaics have become significantly more affordable and there are many finance options available. But these technologies are still not accessible for many households, especially rental properties.

Policies and incentives could make it easier for everyone to afford solar-powered homes. Having public buildings with solar panels in every community would enable basic access to energy for everyone.

Potential of distributed solar power

To visualise how solar infrastructures could be distributed in cities, we use the size of New Zealand’s largest solar farm as an example.

With a total land area of 93 hectares and 63 megawatts of capacity, the solar plant will generate enough renewable energy to power approximately 13,000 homes. We explore how this land area could be distributed on Auckland’s rooftops.

The map above applies the total land area of the solar farm to 14 of the largest building rooftops in Auckland.

The map below distributes this power more evenly to communities by utilising the rooftops of schools and supermarkets, totalling 167 buildings.

Both scenarios show how we could better utilise the space available on rooftops in our cities. The second scenario presents a higher potential of creating resilient communities due to its geographical distribution; these places could help locals during power outages.

Locally generated solar power is key to resilient, sustainable cities and New Zealand’s transition to a zero-carbon future. Decentralised renewable energy, especially building-integrated solar power, brings power generation closer to consumption.

In a country subject to multiple natural hazards, investment in solar for public buildings and homes could bring several benefits for disaster resilience and climate change mitigation.

The new wave of artificial intelligence – so-called AI – is bringing with it promises as well as threats.

By assisting workers, it can raise productivity and boost real wages. By making use of large, underutilised data, it can improve outcomes in services including retailing, health and education.

The risks include deepfakes, privacy abuse, unappealable algorithmic decisions, intellectual property infringement and wholesale job losses.

Both the risks and the potential benefits seem to grow by the day. On Thursday Open AI released new models it said could reason, performing complex calculations and drawing conclusions.

But, as a specialist in competition and consumer protection, I have formed the view that calls for new AI-specific regulations are largely misguided.

Most uses of AI are already regulated

A Senate committee is about to report on the opportunities and impacts of the uptake of AI, and I helped draft the Productivity Commission’s submission.

Separately, the government is consulting about mandatory guardrails for AI in high-risk settings, which would function as a sort of checklist for what developers should consider alongside a voluntary safety standard.

Here’s my thinking: most of the potential uses of AI are already covered by existing rules and regulations designed to do things such as protect consumers, protect privacy and outlaw discrimination.

These laws are far from perfect, but where they are not perfect the best approach is to fix or extend them rather than introduce special extra rules for AI.

AI can certainly raise challenges for the laws we have – for example, by making it easier to mislead consumers or to apply algorithms that help businesses to collude on prices.

But the key point is that laws to control these things exist, as do the regulators experienced in enforcing them.

The best approach is to make existing rules work

One of Australia’s great advantages is the strength and expertise of its regulators, among them the Competition and Consumer Commission, the Communications and Media Authority, the Australian Information Commissioner, the Australian Securities and Investments Commission, and the Australian Energy Regulator.

Their job ought to be to show where AI is covered by the existing rules, to evaluate the ways in which AI might fall foul of those rules, and to run test cases that make the applicability of the rules clear.

It is an approach that will help build trust in AI, as consumers see they are already protected, as well as providing clarity for businesses.

AI might be new, but the established consensus about what is and is not acceptable behaviour hasn’t much changed.

Some rules will need to be tweaked

In some situations, existing regulations will need to be amended or extended to ensure behaviours facilitated by AI are covered. Approval processes for vehicles, machinery and medical equipment are among those that will increasingly need to take account of AI.

And in some cases, new regulations will be needed. But this should be where we end up, not where we begin. Trying to regulate AI because it is AI will, at best, be ineffective. At worst, it will stifle the development of socially desirable uses of AI.

Many uses of AI will create little if any risk. Where potential harm exists, it will need to be weighed against the potential benefits of the use. The risks and benefits ought to be judged against real-world, human-based alternatives, which are themselves far from risk-free.

New regulations will only be needed where existing regulations – even when clarified, amended or extended – are inadequate.

Where they are needed, they ought to be technology-neutral wherever possible. Rules written for specific technologies are likely to quickly become obsolete.

Last mover advantage

Finally, there’s a lot to be said for becoming an international “regulation taker”. Other jurisdictions such as the European Union are leading the way in designing AI-specific regulations.

Product developers worldwide, including those in Australia, will need to meet those new rules if they want to access the EU and those other big markets.

If Australia developed its own idiosyncratic AI-specific rules, developers might ignore our relatively small market and go elsewhere.

This means that, in those limited situations where AI-specific regulation is needed, the starting point ought to be the overseas rules that already exist.

There’s an advantage in being a late or last mover. This doesn’t mean Australia shouldn’t be in the forefront of developing international standards. It merely means it should help design those standards with other countries in international forums rather than striking out on its own.

The landscape is still developing. Our aim ought to be to give ourselves the best chance of maximising the gains from AI while providing safety nets to protect ourselves from adverse consequences. Our existing rules, rather than new AI-specific ones, ought to be where we start.

Where do clowns come from? In popular culture, they may come from alien worlds, such as Killer Klowns from Outer Space, peer out from drains like Pennywise from Stephen King’s It, or emerge from a vat of chemicals or a lab accident, like The Joker in DC comics.

In real life, however, they often come from clown schools, theatre institutes or universities.

Clown education is often long, rigorous and very physically demanding. Many clown courses are quite hard to get into.

So, how are they trained and what are some of the main institutions?

We’ve always had clowns

The clown is an anthropological constant, a phenomenon that exists across cultures and time.

From “ritual clowns” in indigenous cultures, to the “court bufoons” that traditionally entertained Pacific chiefs and royal jesters in medieval Europe, there are many different types of clowns. And they serve different purposes in society.

Clowns are often afforded special privilege to say or do what would be unthinkable for most of us. As one research paper notes:

The earliest record of clowns or jesters appear to date back to Ancient Egypt over 4,000 years ago, where a ‘Danga’ is recorded as a fool at the court of the Pharaoh Dadkeri-Assi […] his activities, dances and diversions were treated not only with tolerance but also with privilege.

Clowns also appear in the literature on ancient Greece and ancient Rome, again enjoying positions of relative privilege at the time.

The stock characters and themes explored in the Commedia dell’arte – a theatre tradition that flourished between the 16th and 18th centuries in Europe – became the source of many Harlequins and Pierrots, Punches and Judies.

In the 18th century, with the rise of the modern circus and pantomime, the mischievous clown became popular. This was most famously personified by English clown Joseph Grimaldi, who wore white face paint and is described by one report as having “invented the creepy clown” with his unsettling acts of mischief.

Since then, many more whiteface clowns and mimes (such as clowning legend, Lindsay Kemp, who studied mime with France’s Marcel Marceau and worked with David Bowie and Kate Bush), Auguste clowns (who wear red noses and are often in grotesquely mismatched costumes), character clowns (such as The Three Stooges or The Marx Brothers), tramps (such as Charlie Chaplin) and many other clown incarnations have populated our cultural imagination.

Today’s clowns may be entertainers, political activists, boundary-pushers, or even medical clowns performing to relieve people’s physical and emotional pain in hospitals or aged care settings.

All of these require different skills and training.

How are clowns trained?

The methods, techniques and schools of clowning are as diverse as the cultural history of clowns itself.

Not surprisingly, many circuses train clowns.

Among the well-known schools in the United States was Ringling Bros. and Barnum & Bailey Clown College, which educated clowns until it closed in 1997 (one famous graduate is Penn Jillette from the magic-performing duo Penn and Teller).

Theatre schools often train clowns, too. One example is Accademia Dimitri in Switzerland, founded by Swiss clown Dimitri, his wife Gunda, and Czech-born actor and mime Richard Weber. The program they designed focuses on teaching students pantomime, dance, theatrical improvisation, acrobatics and other skills.

Universities also train clowns. The University of Alberta in Canada, for example, has a Movement, Dance and Clowning stream.

In fact, there are clown and physical theatre hubs all around the world that train clowns.

The Budapest Circus Arts and Contemporary Dance College, for example, offers a three-year clown training programme. Students learn skills in “preparing the body, the mind and the spirit for creation”, improvisation techniques, circus studies, juggling, clowning technique and acrobatics.

There’s also the famous École Internationale de Théâtre Jacques Lecoq in France. One well-known graduate is Australian actor Geoffrey Rush, who studied mime and movement there.

There’s Sydney’s Clown Institute, which describes itself as a “fun-tastic outlet to ditch stress”.

Then there are also mentoring-based approaches to clown training that tap into literature and art (see, for example, the International School for Acting And Creativity).

All of these approaches help future clowns develop their artistic and expressive pathways by combining technical skills with personal artistic sensibilities.

But it is the clown’s purpose that shapes the direction of the training.

How purpose shapes training

If you want to become a professional mime (with or without whiteface), you will likely learn the techniques developed by groundbreaking artists such as France’s Marcel Marceau and Étienne Decroux, who spearheaded a type of physically demanding performance known as corporeal mime.

A mime may also study improvisation, ballet, modern dance, acrobatics and fencing.

If you want to become a circus clown, your training may include classical acting techniques, interdisciplinary circus arts and dance, physical comedy, acrobatics, yoga, stage combat, juggling and storytelling.

Clown doctors often undertake specialist training in performing arts such as physical theatre, pantomime or puppetry, as well as learning practical skills in nursing, hospital practices and procedures. They must adapt their clowning to a therapeutic profession in a medical setting.

One medical clowning organisation, Dream Doctors, says that after inital training, their graduates undertake about 200 hours of ongoing professional development seminars, courses and workshops every year.

Clowns master the body as a storyteller

Trained clowns create engaging experiences for audiences, generate memorable moments and harness the power of creativity for wellbeing and social change.

Through institutionalised programmes, mentoring by senior colleagues and the study of routines they admire, future clown performers must discover and unfold their own inner clown.

Trained clowns master the body as a storyteller, fostering new artistic creation and stimulating creative intelligence.

Australia is no stranger to extreme weather. From heatwaves and droughts to flooding rains, hailstorms or fire weather, our continent experiences it all.

To help Australians prepare for these hazards, the Bureau of Meteorology regularly briefs emergency services and governments, along with providing forecasts and advanced warnings for the public when severe weather approaches.

The latest spring and summer briefing shows the rest of this year is likely to be warmer than normal, with more extreme heat events possible.

We need to prepare for fire risks and severe storms. There’s also every chance the nation could experience multiple extreme events at any one time – concurrently or in rapid succession – in different parts of the country. Here’s what we expect to see.

Our most severe weather usually starts in October

Australia’s severe weather season is really from October to April.

But in the past few weeks, we’ve seen extreme heat across most of the country, severe winds in the southeast, floods in Tasmania, and even damaging hail in parts of Victoria.

With those unusually extreme events already happening across much of Australia, many people will be worried about the next few months.

The Bureau of Meteorology monitors current conditions and the drivers of Australian climate, then forecasts weather for the coming days and climate conditions for the coming months.

On Friday, the bureau’s general manager for environmental prediction, Matt Collopy, presented this outlook below at the National Situation Room in Canberra.

What will the rest of 2024 look like?

Australia’s climate and the likelihood of severe weather varies depending on the behaviour of climate drivers, such as the El Niño-Southern Oscillation and Indian Ocean Dipole. This is particularly true at this time of year, when the connections between these drivers and Australian weather and climate are strongest.

At the moment, we have neutral conditions in both the Pacific and Indian Oceans, but a higher-than-normal likelihood of a La Niña developing. Without strong climate drivers, the seasonal outlook for Australia is less certain than if we had established El Niño/La Niña or positive/negative Indian Ocean Dipole events in place.

Nevertheless, with a higher chance of La Niña, a slightly wetter-than-normal outlook, and above-average rates of runoff already flowing into some eastern Australian rivers, the chance of river flooding is higher than normal for the next few months, particularly in Tasmania. On the plus side, wetter than average soils across much of eastern Australia reduces the risk of dust storms in coming months.

Western and Central Victoria, on the other hand, have had a dry few months and river flows are below average. Drought is continuing and there’s not a strong signal for either wet or dry conditions in the seasonal outlook for this region.

The risks of a very warm spring

Having just experienced the warmest August on record, it is perhaps no surprise that Australia is likely to have another very warm spring. This is accompanied by a heightened chance of extreme heat events.

Continued high temperatures in the seas around Australia raise the chance of marine heatwaves, particularly in the Tasman Sea this spring.

With the warmer conditions and a lack of a strong rainfall signal in the forecast, there is a raised risk of bushfires this spring across much of northeastern Australia, as well as in the drought-affected areas of Victoria and southeastern South Australia. A summer bushfire outlook will come in November.

The bureau is also warning people in and around Canberra to beware of thunderstorm asthma, in which storms induce breathing difficulties. But these events are hard to forecast this far out from October-December, when such events are most frequent.

Similarly, while tropical cyclones are a major weather hazard across northern Australia, it is hard to make useful forecasts for the summer and early autumn season at this stage. The bureau will publish its tropical cyclone outlook next month.

Preparing for more extremes

With so much potential for extreme weather and significant risks to lives and livelihoods, it’s useful to know what lies ahead.

The outlook helps Australians prepare for the severe weather on the horizon. As the climate varies from one year to the next, the likelihood of different types of severe weather changes. This is happening on top of background trends related to the warming of the planet.

In the future, with continued global warming, Australians will experience more extreme heat and there will more often be a heightened risk of bushfires.

In Australia’s southwest and southeast, we expect droughts to worsen too, while increases in short-duration extreme rainfall are on the cards for most of us.

Forecasting of extreme weather will continue to improve, helping us prepare for some hazards. But reducing greenhouse gas emissions will also help to limit rises in the frequency and intensity of these extreme weather events.

As the US Presidential debate wrapped up on Wednesday, commentators and journalists regrouped and drew breath.

But then, enter Taylor Swift. The pop superstar posted her endorsement of the Kamala Harris and Tim Walz ticket on social media. She followed it up by reminding the public to register to vote in her speech at the MTV Video Music Awards.

People listened. Within 24 hours, more than 400,000 visitors hit the voter registration website.

It’s always tempting to question the relevance of celebrity political endorsements. After all, endorsing products and brands is par for the course. So does a political nod from Taylor Swift really matter?

It sure does. It matters particularly to the young white women who form large parts of her engaged fanbase. Mobilising these women could have a huge impact on who turns up to vote – and ultimately, who wins the tight presidential race.

Why Taylor Swift?

The Harris campaign has already received its fair share of celebrity advocacy, most notably Charli XCX’s early declaration that Kamala is brat.

Beyonce hasn’t said anything explicitly, though she has given her tacit endorsement by giving Harris the right to use her song “Freedom” in advertising material.

Swift’s explicit endorsement adds a new level: it’s not just about having the backing of a singer, but of a cultural phenomenon.

Coming off the back of the European leg of the Eras Tour (the highest-grossing tour of all time), Swift has shown she can mobilise and energise millions of people. The Democrats would be wanting to tap into that.

She has 284 million Instagram followers. That’s an audience campaign strategists can only dream of.

It’s not the first time Swift has weighed in on political matters. That was in the 2018 midterms, when she urged her followers not to vote for Tennessee Republican senate nominee Marsha Blackburn.

Blackburn was ultimately elected, but Swift has continued to engage in politics. Last year, she used Voter Registration Day to call for people to sign up to vote. More than 35,000 people heeded the call.

Style and substance

It’s not surprising Swift threw her weight behind the Democrats, especially given the campaign’s focus on reproductive and minority rights.

Especially since 2019, Swift has advocated for these causes in her music. They’re causes she shares with many swifties.

This is why the endorsement is so crucial. While swifties are a group already primed to support Harris and Walz, getting them to vote is the key challenge. If mobilising large numbers of people is the goal, Swift is surely the person to help achieve it.

But swifties voting for the Democrats won’t just be doing so because their favourite singer told them to. It’s because they themselves believe in the substance of the policies put forward.

When one in three women in the United States live in a state with either full or heavily restrictive abortion bans, the impact on the lives of those women cannot be understated. These are issues that matter deeply to young women and LGBTQI+ communities.

Strategic timing

Swift’s wording in her statement was entirely deliberate. While she outlined why she’d be supporting Harris, she didn’t directly tell anyone to vote for the Democrats. Instead, she encouraged people to do their research and register to vote.

This degree of separation provides Swift with some plausible deniability from inevitable Republican attacks. As the Trump campaign seeks to paint the opposition as a bunch of rich, white, east coast elites, avoiding the direct call for swifties to vote for Harris blunts that attack. It’s also entirely in line with Swift’s approach to her fanbase more broadly, and implicitly supports Harris’ argument that women should be able to make their own decisions.

The timing, on the other hand, might not have been quite so mutually advantageous.

While Harris would clearly take a Swift endorsement in whatever form it came, one can imagine Democratic strategists might want to put more distance between it and the debate. That way, they could ride high off the debate, then have the Swift support as a standalone story down the line.

The rationale behind announcing it directly after the debate is unclear, but perhaps Swift wanted to use it to illustrate her independence from the Democrat party machine. Being speculative, it seems the timing was on her terms.

Of course, the party jumped on the opportunity. Friendship bracelets that went on sale minutes after the endorsement sold out almost immediately.

An Eras Tour vibe

One interesting part of Swift’s post is the explicit mention of Walz and his policy priorities.

Walz injected a sort of joyous dad quality to the Harris campaign. He regularly tells stories about helping care for your neighbours and being free to love whomever you love.

In many ways, Walz represents a dad at the Eras Tour supporting his daughters. He typifies a different sort of masculinity: one that isn’t intimidated by strong, successful women, and is not afraid to shake it off in a glitter-filled, girl-dominated space.

The Eras Tour has been filled with these examples of community-building. It’s demonstrated the power of the collective, spontaneous friendship and caring for each other, even if you’re strangers.

While the strength of the Trump vote shows there’s still widespread support for angry politics, many Americans are tired of being scared and threatened with violence.

Until the Harris campaign, there wasn’t a clear alternative energy. Now there is, and it’s not unlike the energy that thousands of girls and women (and their dads) bring to stadiums to watch Taylor Swift perform.

This could have a tangible impact on the election result. While untangling precisely what wins elections is always difficult, a Harris win could come down to only a couple of thousand votes in some swing states.

One extremely tight race is in Swift’s home state of Pennsylvania. If Swift motivated even a small portion of people to vote when they otherwise wouldn’t have engaged, it could have an outsized impact.

The Albanese government has this week announced it will introduce one of the largest reforms to Australia’s aged-care sector to date.

The package includes a A$4.3 billion investment in home care, now called “Support at Home”, to come into effect from July 2025. This reflects both the desire of many people to remain living at home as they age, and the government’s desire to reduce the costs of residential aged care.

So what changes is the government making to home care packages? And what will these changes mean for ageing Australians?

Reducing waiting times

One of the major complaints about the current home care system is the long waiting times. Estimates suggest there’s a 6–to-12-month wait for the higher level 3 and 4 home care packages. For people with the highest needs, this is far too long.

As of March this year, around 45,000 people were waiting for any level of home care. An additional 14,000 were already receiving a package, but on a lower level of home care than they were entitled to.

With additional funding, the new system will support more participants. It aims to shorten wait times to an average of three months from July 2027.

Changes to services

The new system will replace the current four levels of home care packages with eight classifications of funding for services. When participants are assessed, they will be assigned the most suitable category. There’s currently very limited information on what these classifications are, but the idea is they will provide more targeted services.

A number of short-term supports will also be available. These include assistive technology (such as mobility aids) and home modifications. Some people will be able to access 12 weeks of restorative care – a more intensive program designed to build function after injury or illness – as well as palliative care support.

The way different types of services are subsidised is also changing. Previously, the same means-tested co-contribution applied regardless of the type of service.

Under the new system, services are categorised into clinical care (for example, physiotherapy or wound care), independence (such as help with bathing or cooking) and everyday living (for example, gardening or home maintenance). The new reforms fully subsidise clinical services regardless of income, whereas independence and everyday living services will attract co-contributions based on means testing.

For example, a self-funded retiree would pay nothing out of pocket for physiotherapy, but would pay 50% for help with showering and 80% towards gardening costs. A full pensioner would also pay nothing for physiotherapy, but pay 5% for help with showering and 17.5% of the cost of gardening.

This is a positive change. Our research has previously highlighted a tendency for people with home care packages to choose everyday living services such as gardening and cleaning and refuse clinical care such as allied health and nursing as these types of services were more expensive.

These changes should make older people more likely to choose allied health and clinical care services, which will help them maintain their function and stay fitter for longer.

Some challenges

For the government’s reforms to deliver faster and better support at home, a number of issues need to be addressed.

As people stay at home for longer, we also see that these people are frailer and have more health conditions than in the past. This requires a different and more highly skilled home care workforce.

The current home care workforce consists largely of personal care and domestic support workers alongside a much smaller skilled workforce of registered nurses and allied health professionals.

But with the changing profile of people receiving care at home, there will need to be a greater focus on maintaining functional capacity. This might mean more allied health input will be required, such as from physiotherapists and occupational therapists.

It’s difficult to source an appropriately skilled workforce across the sector, and almost impossible in rural and remote areas. Alternative models, such as training personal care workers to act as allied health assistants, and effectively using technology such as telehealth, will be necessary to meet demand without compromising on quality of care.

One example of the need for upskilling in specific areas relates to caring for people with dementia. The majority of people who are living with dementia at home receive care from family carers, supported by home care workers. It’s vital that these care workers have adequate knowledge and skills specific to dementia.

However, research has shown the home care workforce may lack the knowledge and skills to provide best-practice care for people living with dementia. Specialised dementia training for home care workers is effective in improving knowledge, attitudes and sense of competence in providing care. It should be rolled out across the sector.

What about unpaid care at home?

Unpaid carers, such as family members, provide significant amounts of care for older people. The value of this unpaid care is estimated to be in the billions. As older people stay at home for longer, this is set to increase even further.

However, carers with high care burdens are particularly vulnerable to poor physical and mental health. Without adequate support, we may find extra caring pressures lead to a breakdown in caring relationships and an increase in other health-care costs for both the carer and care recipient.

So we need to ensure carers have adequate financial, psychological and practical support. But the currently available detail on the reforms doesn’t indicate this has been adequately addressed.

With careful implementation and ongoing evaluation, these reforms have the potential to significantly enhance the home care system. However, their success will depend on addressing workforce challenges, ensuring adequate support for unpaid carers, and maintaining a focus on the holistic needs of older Australians.
