Around 3% of us will develop a brain aneurysm in our lives. So what is it and how do you treat it?

Australian radio host Kyle Sandilands announced on air yesterday that he has a brain aneurysm and needs urgent brain surgery.

Typically an aneurysm occurs when a part of the wall of an artery (a type of blood vessel) becomes stretched and bulges out.

You can get an aneurysm in any blood vessel, but they are most common in the brain’s arteries and the aorta, the large artery that leaves the heart.

Many people can have a brain aneurysm and never know. But a brain (or aortic) aneurysm that ruptures and bursts can be fatal.

So, what causes a brain aneurysm? And what’s the risk of rupture?

Weakness in the artery wall

Our arteries need strong walls because blood is constantly pumped through them and pushed against the walls.

An aneurysm can develop if there is a weak part of an artery wall.

The walls of arteries are made of three layers: an inner lining of cells, a middle layer of muscle and elastic fibres, and a tough outer layer of mostly collagen (a type of protein). Damage to any of these layers causes the wall to become thin and stretched. It can then balloon outward, leading to an aneurysm.

Genetics and certain inherited disorders can cause weak artery walls and brain aneurysms in some people.

For all of us, our artery walls become weaker as we age, and brain aneurysms are more common as we get older. The average age for a brain aneurysm to be detected is 50 (Sandilands is 53).

Females have a higher risk of brain aneurysm than males after about age 50. Declining oestrogen around menopause reduces the collagen in the artery wall, causing it to become weaker.

High blood pressure can increase the risk of a brain aneurysm. In someone with high blood pressure, blood inside the arteries is pushed against the walls with greater force. This can stretch and weaken the artery walls.

Another common condition called atherosclerosis can also cause brain aneurysms. In atherosclerosis, plaques made mostly of fat build up in arteries and stick to the artery walls. This directly damages the cell lining, and weakens the muscle and elastic fibres in the middle layer of the artery wall.

Several lifestyle factors increase risk

Anything that increases inflammation or causes atherosclerosis or high blood pressure in turn increases your risk of a brain aneurysm.

Smoking and heavy drinking affect all of these, and nicotine directly damages the artery wall.

Sandilands mentioned his cocaine use in discussing his diagnosis. He said:

The facts are, a life of cocaine abuse and partying are not the way to go.

Indeed, cocaine abuse increases the risk of a brain aneurysm. It causes very high blood pressure because it causes arteries to spasm and constrict. Cocaine use is also linked to worse outcomes if a brain aneurysm ruptures.

Stress and a high-fat diet also increase inflammation. High cholesterol can also cause atherosclerosis. And being overweight increases your blood pressure.

A study of more than 60,000 people found smoking and high blood pressure were the strongest risk factors for a brain aneurysm.

Is it always a medical emergency?

About three in 100 people will have a brain aneurysm, varying in size from less than 5mm to more than 25mm in diameter. The majority are only discovered while undergoing imaging for something else (for example, head trauma), because small aneurysms may not cause any symptoms.

Larger aneurysms can cause symptoms because they can press against brain tissues and nerves.

Sandilands described “a lot of headache problems” leading up to his diagnosis. Headaches can be due to minor leaks of blood from the aneurysm. They indicate a risk of the aneurysm rupturing in subsequent days or weeks.

Less than one in 100 brain aneurysms will rupture, often called a “brain bleed”. This causes a subarachnoid haemorrhage, which is a type of stroke.

If it does occur, rupture of a brain aneurysm is life-threatening: nearly one in four people will die within 24 hours, and one in two within three months.

If someone’s brain aneurysm ruptures, they usually experience a sudden, severe headache, often described as a “thunderclap headache”. They may also have other symptoms of a stroke such as changes in vision, loss of movement, nausea, vomiting and loss of consciousness.

Surgery can prevent a rupture

Whether surgery will be used to treat a brain aneurysm depends on its size and location, as well as the age and health of the patient. The medical team will balance the potential benefits with the risks of the surgery.

A small aneurysm with low risk of rupture will usually just be monitored.

However, once a brain aneurysm reaches 7mm or more, surgery is generally needed.

In surgery to repair a brain aneurysm, the surgeon will temporarily remove a small part of the skull, then cut through the coverings of the brain to place a tiny metal clip to close off the bulging part of the aneurysm.

Another option is endovascular (meaning within the vessel) coiling. A surgeon can pass a catheter into the femoral artery in the thigh, through the aorta to the brain. They can then place a coil inside the aneurysm which forms a clot to close off the aneurysm sac.

After either surgery, usually the person will stay in hospital for up to a week. It can take 6–8 weeks for full recovery, though doctors may continue monitoring with annual imaging tests for a few years afterwards.

You can lower your risk of a brain aneurysm by not smoking, moderating alcohol intake, eating a healthy diet, exercising regularly and maintaining a healthy weight.

As Trump deportations intensify, Pacific Island nations worry they could be overwhelmed

Source: The Conversation (Au and NZ) – By Henrietta McNeill, Research fellow, Australian National University

In his first term, Donald Trump deported far fewer people from the United States than his three predecessors: Barack Obama, George W. Bush and Bill Clinton.

Just weeks into his second term, however, Trump is making the deportation of immigrants one of his top priorities. Immigration raids on those who have overstayed their visas and non-citizens with criminal histories have already commenced, with arrests increasing dramatically in recent days.

His administration has announced plans to build a migrant detention facility at Guantanamo Bay in Cuba that could hold up to 30,000 people awaiting deportation. Trump has also threatened to use a little-known law from 1798 to speed up the process, bypassing immigration courts.

While much of the attention has focused on the hundreds of thousands of migrants at risk of being deported to Latin America, many Pacific islanders are likely to be ordered to leave, as well.

A list from the US Immigration and Customs Enforcement of people with “final orders of removal” includes some 350 migrants from Fiji, 150 from Tonga and 57 people from Samoa, among others.

Unsurprisingly, Trump’s threats have invoked fear across the Pacific. Prominent Fijian lawyer Dorsami Naidu told the ABC:

We’ve had lots of people who have served prison sentences in America get sent back to Fiji where they introduce different kinds of criminal activities that they are well-groomed in.

It should be noted, though, that not all of the people with orders to leave have been convicted of serious crimes. Many have simply overstayed their visas or may have only committed a minor infraction. Most want to turn their lives around.

Lack of support

Criminal deportations from the US, Australia and New Zealand have increased dramatically over the past decade, yet there is still a crucial lack of funding to support reintegration services.

Concerns about the repercussions of criminal deportations are particularly high in Tonga, which received more than 1,000 returnees from 2009–20, nearly three-quarters of whom were from the US.

One Tongan commentator suggested Trump’s decision would “unleash a wave of deportees that could drown Tonga and other Pacific nations in crisis”.

Though some Tongan returnees are accepted back into families and societies, many struggle. A large number left the country when they were young and often have limited understanding of the local language and culture. As such, they experience difficulties reintegrating into society.

My research shows that some deported Pacific islanders with criminal histories may turn “back to what they know” in the absence of support, which at times means involvement in the drug trade if there are no other means of gainful employment.

In countries like Tonga where there is an escalating methamphetamine problem and a lack of employment opportunities, this is understandably concerning.

Tonga, like other Pacific countries, struggles to fund organisations that crucially assist with deported peoples’ reintegration needs in order to prevent the risk of (re)offending. The countries deporting these individuals (such as the US, New Zealand or Australia) rarely provide any assistance, despite repeated requests from Pacific governments and non-governmental organisations.

Can these countries negotiate instead?

Countries can push back against Trump’s decisions to deport their citizens. Colombia was the first to do so, when President Gustavo Petro initially refused to allow military planes carrying deported migrants to land.

Petro’s refusal was met with fury in Washington. Trump threatened a number of retaliatory trade measures, prompting Petro to eventually relent.

Pacific states have previously tried to push back against deportations during the COVID pandemic. Samoa and Tonga, for instance, used diplomatic channels to request a “pause” on removals while they grappled with the unfolding health crisis.

Australia and New Zealand complied with the request, but the US did not. Instead, it used punitive measures to force states into continue receiving deportations.

For instance, the US blacklisted Samoan and Tongan nationals from the list of states eligible for seasonal work visas, affecting these countries’ economies. They were not returned to the list until they “complied” with US removals.

International law mandates that countries accept their own citizens if they are deported. Those that refuse are deemed “deviant states”, which can cause problems for both the deporting state and returnees trapped in limbo.

However, there are other ways of delaying deportation orders.

For example, Samoa has requested additional information from the countries trying to deport Samoans and will not issue travel documents (for example, a passport) until this request is complied with. This information includes evidence of an individual’s connection to Samoa and family ties in the country.

Samoan authorities maintain this helps organisations like the Samoa Returnees Charitable Trust find their families and arrange appropriate accommodation, aiding with their reintegration.

Countries like Colombia and Samoa are acting in the interests of their citizens. While many have legitimate concerns about returnees potentially turning to crime once they are in their home countries, these states also want to challenge the perception that all migrants are criminals.

As Petro, the Colombian president, was quick to point out:

They are Colombians. They are free and dignified, and they are in their homeland where they are loved […] The migrant is not a criminal. He is a human being who wants to work and progress, to live life.

Do big tech companies have a ‘duty of care’ for users? A new report says they do – but leaves out key details

Source: The Conversation (Au and NZ) – By Lisa M. Given, Professor of Information Sciences & Director, Social Change Enabling Impact Platform, RMIT University

Large social media companies should have to proactively remove harmful content from their platforms, undergo regular “risk assessments” and face hefty fines if they don’t comply, according to an independent review of online safety laws in Australia.

The federal government will today release the final report of the review conducted by experienced public servant Delia Rickard, more than three months after receiving it.

The review comes a few months after Meta announced it will stop using independent fact checkers to moderate content on Facebook, Instagram and Threads.

Rickard’s review contains 67 recommendations in total. If implemented, they would go a long way to making Australians safer from abusive content, cyberbullying and other potential harms encountered online. They would also align Australia to international jurisdictions and address many of the same problems targeted by the social media ban for young people.

However, the recommendations contain serious omissions. And with a federal election looming, the review is not likely to be acted upon until the next term of government.

Addressing online harms at the source

The review recommends imposing a “digital duty of care” on large social media companies.

The federal government has already committed to doing this. However, legislation to implement a digital duty of care has been on hold since November, with discussions overshadowed by the government’s social media ban for under 16s.

The digital duty of care would put the onus on tech companies to proactively address a range of specific harms on their platforms, such as child sexual exploitation and attacks based on gender, race or religion.

It would also provide several protections for Australians, including “easily accessible, simple and user-friendly” pathways to complain about harmful content. And it would position Australia alongside the United Kingdom and the European Union, which already have similar laws in place.

Online service providers would face civil penalties of 5% of global annual turnover or A$50 million (whichever is greater) for non-compliance with the duty of care.

Two new classes of harm – and expanded powers for the regulator

The recommendations also call for a decoupling of the Online Safety Act from the National Classification Scheme. That latter scheme legislates the classification of publications, films and computer games, providing ratings to guide consumers to make informed choices for selecting age-appropriate content.

This shift would create two new classes of harm: content that is “illegal and seriously harmful” and “legal but may be harmful”. This includes material dealing with “harmful practices” such as eating disorders and self-harm.

The review’s recommendations also include provisions for technology companies to undergo annual “risk assessments” and publish an annual “transparency report”.

The review also recommends adults experiencing cyber abuse, and children who are cyberbullied online, should wait only 24 hours following a complaint before the eSafety Commission orders a social media platform to remove the content in question. This is down from 48 hours.

It also recommends lowering the threshold for identifying “menacing, harassing, or seriously offensive” material to that which “an ordinary reasonable person” would conclude is likely to have an effect.

The review also calls for a new governance model for the eSafety Commission. This new model would empower the eSafety Commissioner to create and enforce “mandatory rules” (or codes) for duty of care compliance, including addressing online harms.

The need to tackle misinformation and disinformation

The recommendations are a step towards making the online world safer for everybody. Importantly, they would achieve this without the problems associated with the government’s social media ban for young people – including that it could violate children’s human rights.

Missing from the recommendations, however, is any mention of potential harms from online misinformation and disinformation.

Given the speed of online information sharing, and the potential for artificial intelligence (AI) tools to enable online harms, such as deepfake pornography, this is a crucial omission.

From vaccine safety to election campaigns, experts have raised ongoing concerns about the need to combat misinformation.

A 2024 report by the International Panel on the Information Environment found experts, globally, are most worried about “threats to the information environment posed by the owners of social media platforms”.

In January 2025, the Canadian Medical Association released a report showing people are increasingly seeking advice from “problematic sources”. At the same time technology companies are “blocking trusted news” and “profiting” from “pushing misinformation” on their platforms.

In Australia, the government’s proposed misinformation bill was scrapped in November last year due to concerns over potential censorship. But this has left people vulnerable to false information shared online in the lead-up to the federal election this year. As the Australian Institute of International Affairs said last month:

misinformation has increasingly permeated the public discourse and digital media in Australia.

An ongoing need for education and support

The recommendations also fail to provide guidance on further educational supports for navigating online spaces safely in the review.

The eSafety Commission currently provides many tools and resources for young people, parents, educators, and other Australians to support online safety. But it’s unclear if the change to a governance model for the commission to enact duty of care provisions would change this educational and support role.

The recommendations do highlight the need for “simple messaging” for people experiencing harm online to make complaints. But there is an ongoing need for educational strategies for people of all ages to prevent harm from occurring.

The Albanese government says it will respond to the review in due course. With a federal election only months away, it seems unlikely the recommendations will be acted on this term.

Whichever government is elected, it should prioritise guidance on educational supports and misinformation, along with adopting the review’s recommendations. Together, this would go a long way to keeping everyone safe online.

How can you help your child make friends?

Source: The Conversation (Au and NZ) – By Gretchen Geng, Professor in Innovative Education Futures, Flinders University

One of the things children (and parents) may worry about at the start of the new school year is, will I have friends?

This could be true for children starting or changing schools or simply going back to a new year with different class arrangements.

How can parents talk to their kids about making friends?

Why is it important to have friends?

We research young people’s wellbeing and provide programs to schools on how to talk about mental health.

Having lasting, meaningful friendships is extremely important for children’s health, development and wellbeing.

They can validate young people’s aspirations and interests and help them feel like they belong. Friends can also help ease feelings of loneliness and anxiety, making it easier for children to engage in new activities and connect with others.

On top of this, friendships can act as a “buffer” against bullying by providing emotional support if it does happen. Research also suggests, if children don’t have a supportive friendship network, they are more prone to be bullied at school.

Help your child build confidence

Some children find it harder to make friends than others. If your child is shy or introverted they may find it hard to meet new people.

Let them know it is OK to start small. You don’t have to make ten best friends all at once! Making friends takes time and even just one or two good friends can make a big difference.

To break the ice, encourage simple actions such as saying “hello” or offering a compliment: “That’s a cool handball” or “I love your Taylor Swift bracelet”.

Encourage your child to do activities with other kids they enjoy. They can play a particular game or sport or do craft, dancing or reading. Tell them how it’s possible to be friends with lots of different kinds of people.

Talk about the importance of friendship

Research shows it’s important for parents to offer encouragement and guidance about friendships. This can lead to better quality friendships (how well friends get along) as children grow up.

Parents can start to talk to their child about the importance of friendships from a young age. Some questions parents could ask include “Who did you play with today?”, “What did you like about playing with them?”, “What games did you play”.

Parents can also start conversations about the value of friends and friendship. For example, parents could ask their child about the importance of sharing with friends (“it actually feels great to share and make your friends happy”).

Encourage your child to talk

Over time, children’s concept of friendships changes. Younger children view friends as somebody you can play with, while older children see friends as people they can trust and can share emotions and thoughts with.

Research shows, parents can also help this transition with advice and encouragement. Encourage your child to express their feelings and talk about what happens at school, so you can work through any issues or tricky things together.

This does not have to be a formal talk. You could chat while you are doing something else – like drawing, playing chess or throwing a ball.

To create a safe space for your child to freely express their feelings and emotions, avoid being judgemental or critical. Instead, ask questions, like “if you do it again, will you do it differently?” or “was that a kind decision?”

Encourage active listening

You can also encourage your child to be a good and supportive friend.

One way to do this is by being an active listener. This is about understanding what someone is saying (and possibly taking action because of it), not simply “hearing” what is said.

You can suggest your child takes a deep breath and lets the other child finish what they are trying to say, instead of interrupting and talking over people.

Active listening is a skill parents can practise with their child. Make a game and have fun doing it. Try it in the car, over the dinner table or in another informal setting.

Australia won’t escape the fallout of the Trump trade chaos

Source: The Conversation (Au and NZ) – By Scott French, Senior Lecturer in Economics, UNSW Sydney

In a hectic 24 hours of trade diplomacy, US President Donald Trump has paused his threatened 25% tariffs on US imports from Canada and Mexico, while keeping 10% tariffs on imports from China.

Australian companies with operations in Canada or Mexico such as Rio Tinto, whose Canadian operations export billions of dollars of aluminium to the US, have won a temporary reprieve. But the risk of weaker economic growth in China will weigh heavily on companies that export to our largest trading partner.

And Trump has hinted all US imports of aluminium and copper, including from Australia, may be his next target.

The Treasurer Jim Chalmers said on Tuesday that although Australia is not immune when there are escalating trade tensions, “we are pretty well-placed to navigate them.”

However, even if Australia manages to stay out of Trump’s sights, Australians cannot expect to come out of a trade war unscathed. Due to the complexity of global supply chains, it is difficult to predict exactly how Australia would be affected, but here are a few key factors that would likely come into play.

Our largest trading partner

About 40% of Australia’s exports go to China, making it the biggest destination by far, according to data for 2023 from UN Comtrade. Most of this is Australian iron ore and other minerals that are used in China’s construction and manufacturing sectors.

If Trump’s tariffs further slow the
already sluggish Chinese economy, this will reduce demand for the goods it buys from Australia.

If China’s demand for iron ore falls significantly, this will not only hurt the Australian mining sector, but it could trigger a fall in the Australian dollar, making the things Australians buy from abroad more expensive.

But the size of the impact of the latest tariffs on China remains to be seen. China has already absorbed the tariffs from the first Trump administration, and the latest increase is much smaller than the 60% tariff he previously proposed.

Trade diversion

The one positive effect for Australia of US tariffs on other countries is that, because they raise the price of other countries’ exports to the US, they may make some Australian exports more competitive. This is something economists call trade diversion. For example, the tariffs on Canadian aluminium would have shifted US demand toward aluminium produced in Australia.

The tariffs on China will divert relatively little trade to Australia because there is not much overlap between the products China and Australia export to the US.

But China’s retaliatory tariffs could make a significant impact. China responded to the US tariffs imposed during Trump’s first term with tariffs on American wheat and other agricultural products. A similar move this time could create an opening for Australian farmers to fill the gap.

But it is not all good news. The US exports diverted away from the Chinese market will also compete with Australian products in other countries. So, while Australian wheat may become more competitive in China, US wheat may displace Australia’s in the Philippines.

A weaker Aussie dollar?

Tariffs also tend to cause the currency of the country imposing them to rise because they reduce demand for goods denominated in foreign currencies.

The flip side is a weaker Australian dollar, which dropped to a five-year low after the tariffs were flagged. The currency has now fallen nearly 10% since November.

Again, this raises the cost of imports to Australia, which could lift inflation.

Network disruption

If the tariffs on Canada and Mexico are confirmed in 30 days’ time, the greatest impact will be in the supply chain disruption they will cause.

Analyses of the tariffs Trump imposed on China in 2018 found most of the cost was borne by US businesses that use imported inputs. But because North American production networks are so highly integrated, and have been for decades, the effect of tariffs on Canada and Mexico will be much more disruptive to all North American producers.

As economic networks expert Ben Golub explains, the concern is not just that auto prices will rise, but that if key parts of the production network fail, such as if small but important intermediate suppliers go out of business, the effects of the tariffs could cascade into major disruptions.

Eventually, businesses will develop alternative supply chains, but the short-run pain could be considerable.

For Australians, this could mean higher prices and supply disruptions, not just for the products we buy from the US, but for anything that depends on a North American supplier at any stage in the production process.

We are still feeling the effects of the supply chain disruptions caused by COVID, including the jump in inflation in 2021 and 2022 and the subsequent high interest rates and global backlash against incumbent political parties. That includes Donald Trump’s return to the Oval Office.

Similar disruptions may be in store if this skirmish becomes a major global trade war. Even if Trump’s promised tariffs never actually materialise, we may still see the same effects on a smaller scale because the trade policy uncertainty from just the threat of a trade war has similar effects on business activity as actual tariffs.

Whatever transpires, even if Australia can escape direct involvement in a trade war, it cannot escape the shockwaves that reverberate through the global economy. The question is whether it will be a ripple or a tsunami.

What are cooling blankets? Can they really help me sleep?

Source: The Conversation (Au and NZ) – By Linda Grosser, Research Associate, Behaviour-Brain-Body Research Centre, University of South Australia

EGHStock/Shutterstock

You wake up exhausted from yet another hot night of tossing and turning, with very little sleep.

So you might be tempted to buy a “cooling blanket” after reading rave reviews on social media. Or you might have read online articles with taglines such as:

Stop waking up in a puddle of sweat with our roundup of the best cooling blankets – including a top-rated option from Amazon that ‘actually works’.

But what are cooling blankets? And can they help you get a restful night?

We know a cooler bedroom is best

First, let’s look at why a cooler environment helps us sleep better at night.

Our body’s internal temperature has a circadian rhythm, meaning it fluctuates throughout the day. A couple of hours before bed, it drops about 0.31°C to help you fall asleep. It will drop about another 2°C across the night to help you stay asleep.

During sleep, your internal temperature and skin work together to achieve a balance between losing and producing heat. Your skin has sensors that pick-up changes in the environment around you. If it gets too warm, these sensors let your body know, which may cause you to kick-off blankets or bed clothes and wake more often leading to poorer sleep quality.

Sleep quality is an important component of sleep health ensuring you get the physical, mental and emotional benefits that come from a good night’s sleep.

The ideal temperature for sleep varies depending on the season and type of bedding you have but falls between 17°C and 28°C. Keeping your sleeping environment within this range will help you to get the best night’s rest.

So what are cooling blankets?

Cooling blankets are designed to help regulate your body temperature while you sleep.

Different technologies and materials are used in their design and construction.

We’re not talking about hospital-grade cooling blankets that are used to reduce fever and prevent injury to the nervous system. These use gel pads with circulating water, or air-cooling systems, connected to automatic thermostats to monitor someone’s temperature.

Instead, the type of consumer-grade cooling blankets you might see advertised use a blend of lightweight, breathable materials that draw moisture away from the skin to help you stay cool and dry through the night. They look like regular blankets.

Common materials include cotton, bamboo, silk or the fibre Lyocell, all of which absorb moisture.

Manufacturers typically use a thread count of 300-500, creating air pockets that enhance airflow and moisture evaporation.

Some blankets feature a Q-Max rating, which indicates how cool the fabric feels against your skin. The higher the value, the cooler the fabric feels.

Others feature phase change materials. These materials were developed by NASA for space suits to keep astronauts comfortable during a spacewalk where temperatures are from roughly -157°C to 121°C. Phase change materials in cooling blankets absorb and hold heat producing a cooling effect.

Some cooling blankets use NASA technology developed for space suits.

Do they work?

If you believe online reviews, yes, cooling blankets can cool you down and help you sleep better in warmer weather or if you get too hot using normal sheets and blankets.

However, there is little scientific research to see if these consumer-grade products work.

In a 2021 study exploring sleep quality, 20 participants slept for three nights under two different conditions.

First, they slept with regular bed sheets in an air-conditioned room with the temperature set to their preference. Then, they used cooling bed sheets in an air-conditioned room where the temperature was set 3°C higher than their preference.

Participants reported good sleep quality in both conditions but preferred the warmer room with its cooling sheets.

This may suggest the use of cooling bedding may help provide a more comfortable night’s sleep.

But everyone’s cooling needs varies depending on things like age, health, body temperature, the space you sleep in, and personal preferences.

So while these products may work for some people who may be motivated to leave a good review, they may not necessarily work for you.

Are they worth it?

There’s a wide variety of cooling blankets available at different prices to suit various budgets. Positive customer reviews might encourage a purchase, especially for individuals experiencing disrupted sleep at night due to heat.

Yet, these cooling blankets have limited scientific research to show they work and to say if they’re worth it. So it’s up to you.

Lots of choice, but little scientific evidence to back them.

What else can I do if I’m a hot sleeper?

If a cooling blanket isn’t for you, there are other things you can do to stay cool at night, such as:

  • using air conditioning or a fan

  • placing a damp towel under or over you

  • wearing lightweight or minimal sleepwear and avoiding thick or synthetic fabrics, such as nylon, that can trap heat

  • if you usually share a bed, on hot nights, consider sleeping by yourself to avoid excess body heat from your partner.

On a final note, if you often struggle with hot, disturbed sleep, you can check in with your health-care provider. They can see if there is a medical explanation for your disturbed sleep and advise what to try next.

Unwritten rules: why claims of a missing ‘fourth article’ of the Treaty don’t stack up

Source: The Conversation (Au and NZ) – By Paul Moon, Professor of History, Auckland University of Technology

I sign this Treaty with my hand, but with the mana of my ancestors.

So said Hōne Heke, the first rangatira (chief) to sign the Treaty of Waitangi. To emphasise the gravity of this sentiment, he then mentioned two of his predecessors by name: Kaharau and Kauteawha.

It would be difficult to imagine a statement that could invest more mana in the Treaty than this. And Heke was not alone in his view of the agreement.

Many other rangatira similarly regarded the Treaty as a kawenata (covenant) of utmost importance, including some going as far as putting a representation of their tā moko (facial tattoo) on the document.

How each rangatira interpreted the Treaty’s provisions remains open to speculation. But what they committed themselves to abiding by was the text of the agreement (either the English version, or in the case of most signatories, the translation in te reo Māori).

That text was comprised of a preamble, followed by three operative articles. Some rangatira read it, some had it read to them. But as far as all the parties were concerned, that was the entirety of the Treaty.

In the 1990s, however, suggestions began to surface about a mysterious “fourth article” guaranteeing religious protections. It was not part of the text, but supposedly a verbal promise that amounted to a provision of the agreement.

The idea has gained sufficient traction for supporters to petition parliament late last year to recognise the fourth article, just as debate about the Treaty Principles Bill was heating up. But it is a claim that needs to be treated with caution and scrutiny.

Religious protections

Prior to the first signing of the Treaty – at Waitangi – the Anglican missionary Henry Williams had observed that some Catholic rangatira were reluctant to commit to the agreement.

The Catholic Bishop, Jean-Baptiste Pompallier, had queried British motives and insisted Catholic rangatira should receive specific protection from the Crown. Williams then read out a hastily-prepared statement to clarify the issue:

The Governor wishes you to understand that all the Maories (sic) who shall join the Church of England, who shall join the Wesleyans, who shall join the Pikopo or Church of Rome, and those who retain their Maori practices, shall have the protection of the British Government.

Williams noted that this statement “was received in silence. No observation was made upon it; the Maories, and others, being at perfect loss to understand what it could mean.”

And there the matter ought to have ended: a peripheral detail in a momentous day. But this minor episode was disinterred from its historical obscurity in 1995 at a meeting of the New Zealand Catholic Bishops Conference.

The clerics announced that a “fourth article was added to the Maori text of the Treaty signed at Waitangi, at the request of Bishop Jean Baptiste […] This article guaranteed religious freedom for all in the new nation, including Maori.”

Some Anglicans soon endorsed this position. The “fourth article” thus entered the bloodstream of Treaty discourse and began to circulate freely.

Missing evidence

There are several objections to the claim of a fourth article of the Treaty.

Firstly, if it was regarded as a part of the Treaty at the signing on February 6 1840, then we would expect to see both contemporaneous confirmation of this, and subsequent evidence that is consistent with it.

Yet, these categories of evidence are largely absent. Indeed, mention of a “fourth article” before the 1990s does not exist.

The sentiment of the fourth article is also absent from the instructions for the Treaty issued by Lord Normanby, British Secretary of State for the Colonies, in 1839.

Indeed, far from the Crown wishing to guarantee freedom of cultural or religious beliefs, Normanby made it explicit that only those Māori customs the British regarded as acceptable would be protected:

[The] savage practices of human sacrifice and cannibalism must be promptly and decisively interdicted; such atrocities, under whatever plea of religion they may take place, are not to be tolerated in any part of the dominions of the British Crown.

Therefore, as far as one party to the Treaty was concerned, the idea of the fourth article was never in contention. What was explicitly promised to all people was the protection of the British government, and not the protection of all customs held by Māori.

Treaties are written

As every other contemporaneous source confirms, no rangatira sought this fourth article, and around 90% of rangatira who signed the Treaty (in places other than Waitangi) did not have this so-called fourth article read to them (and so could not have consented to it).

Nor was it included in the text of copies of the agreement that were subsequently circulated around the country, and neither Hobson nor Pompallier suggested it was an “article” as such.

International law requires that treaties be in a written form. This certainly has been the convention as far as European treaties are concerned, extending back several centuries.

It makes any suggestion Hobson admitted an oral article extremely problematic. Likewise, New Zealand’s domestic law also specifies the Treaty contains only three articles.

Furthermore, if spoken commitments have the status of an article, then what about other verbal commitments made at some of the Treaty signings? Singling out one statement as a presumed article is inconsistent. Either the principle of all verbal commitments in such a setting constitute articles of the Treaty, or none does.

Previous attempts to insert the fourth article into the country’s constitutional framework have gone nowhere. And in the absence of more persuasive historical evidence, it’s likely to stay that way.

As the late Kingi Tūheitia succinctly put it: “The Treaty is written. That’s it.”

Bees count from left to right just like some humans, apes and birds – new research

Source: The Conversation (Au and NZ) – By Scarlett Howard, Lecturer, School of Biological Sciences, Monash University

Picture writing the numbers 1 to 5 in a horizontal line, from smallest to largest. Where did you put 1? If you placed 1 on the left and 5 on the right, you share this preference with most humans.

Humans are not alone in this preference. Some other primates, and even some birds, also order small-to-large quantities from left to right. Although, some animals do prefer to order quantities from right to left.

This is known as the mental number line, and it shows how brains typically organise information. But why do our brains do this?

To investigate how and why brains order numbers, it’s sometimes useful to step back in time. How did a common ancestor of humans and insects order information? To find out, we can compare the results of humans and bees: we last shared a common ancestor more than 600 million years ago.

Two recent studies on bees have revealed a lot about how tiny brains order numbers.

One study, conducted by a team in Europe, showed that bees prefer to order lower numbers on the left and higher numbers on the right, just like many humans. Our new study, led by Jung-Chun (Zaza) Kuo and her supervisory team, has explored how numbers and space interact in the bee brain.

‘Number’ and ‘space’

As humans, we link the concepts of “space” and “number”. This means there is a logic to how we order numbers (typically from left to right in ascending order: 1, 2, 3, 4 … and so on).

Studies have shown humans may also have a vertical – bottom to top – preference when processing numerical information efficiently.

There may also be educational influences, especially due to language and writing direction. Some languages, like English, write from left to right. Others, such as Japanese, Chinese, Korean, Hebrew or Arabic, can be written in other directions. Writing direction can influence how we prefer to order numbers.

Meanwhile, honeybees are efficient learners and show evidence of being tiny mathematicians. In past research, they have been shown to add and subtract, understand the concept of zero, use symbols to represent numbers, order quantities, categorise numbers by odd or even, and show evidence of linking numbers to spatial information like size.

The competency bees show around numbers makes them an ideal animal to look at how number and space interact in a miniature brain.

Do bees have a mental number line?

How did we test bees in our study?

We gave freely flying bees sugar water for visiting an image of three circles printed on a card: this was our “reference number”. The card was hung in the centre of a large circular screen, with a drop of sugar water on a platform underneath it.

As the bees repeatedly visited the reference number, they learned an association between the number three, the centre of the circular screen, and a reward. In between visits, bees took the sugar water back to their hive to be made into honey.

After bees had learned to associate number (three) and space (middle) with a reward, we tested them on numbers higher and lower than three, to see if they had linked space and number.

We showed bees images of a higher number (four circles) and a lower number (two circles). Two identical images of four shapes were shown simultaneously on the left and right sides of the screen. If bees preferred the larger number on the right, they would fly to the quantity of four presented on the right more than when four was presented on the left.

We did the same for the smaller number of two shapes. If bees preferred four circles on the right and two circles on the left, that would reveal they have a left-to-right mental number line, like humans.

We also tested if bees had a preference to order numbers upwards or downwards, and found no preference for linking space and number vertically. However, bees did prefer options that were towards the bottom of the circular screen.

So, how does the bee mental number line work?

The study by the European team found bees have a consistent left-to-right mental number line. This means they prefer to order lower numbers on the left and higher numbers on the right.

Our study has confirmed bees prefer to order higher numbers on the right. But we also found bees preferred to visit the right side of the screen. The preference of bees to order numbers from left-to-right and to visit the right side of the circular screen interacted in an intriguing way.

The bees in our study showed a preference for higher numbers on the right, but not for lower numbers on the left. This could be because the right-side bias we observed cancelled out the preference for smaller numbers on the left.

Taken together, the findings of both studies confirm that bees do possess a left-to-right mental number line and also that they have a bias towards the right side of their visual space.

Our team suggests such biases – for example, how most humans are right-handed – may be an important part of how brains make sense of ordering information in the world.

The birds and the bees (and the apes)

By looking at the behaviours of animals, we can sometimes learn more about ourselves.

These two recent studies on bees show there is a complex interaction between ordering numbers and how spatial relationships are processed by an insect brain.

We now know that the preference to order numbers from left to right exists in several very different animal groups: insects, birds and apes. Perhaps evolution has landed on this preference as an advantageous way to process complex information.

Whether Biden Or Trump, US’ Latin American Policy Will Be Contemptible

Source: Council on Hemispheric Affairs – Analysis-Reportage

By John Perry and Roger D. Harris

Migration, Drugs, and Tariffs.

With Donald Trump as the new US president, pundits are speculating about how US policy towards Latin America might change.

In this article, we look at some of the speculation, then address three specific instances of how the US’s policy priorities may be viewed from a progressive, Latin American perspective. This leads us to a wider argument: that the way these issues are dealt with is symptomatic of Washington’s paramount objective of sustaining the US’s hegemonic position. In this overriding preoccupation, its policy towards Latin America is only one element, of course, but always of significance because the US hegemon still treats the region as its “backyard.”

First, some examples of what the pundits are saying. In Foreign Affairs, Brian Winter argues that Trump’s return signals a shift away from Biden’s neglect of the region. “The reason is straightforward,” he says. “Trump’s top domestic priorities of cracking down on unauthorized immigration, stopping the smuggling of fentanyl and other illicit drugs, and reducing the influx of Chinese goods into the United States all depend heavily on policy toward Latin America.”

Ryan Berg, who is with the thinktank, Center for Strategic and International Studies, funded by the US defense industry, is also hopeful. Trump will “focus U.S. policy more intently on the Western Hemisphere,” he argues, “and in so doing, also shore up its own security and prosperity at home.”

According to blogger James Bosworth, Biden’s “benign neglect” could be replaced by an “aggressive Monroe Doctrine – deportations, tariff wars, militaristic security policies, demands of fealty towards the US, and a rejection of China.” However, notwithstanding the attention of Trump’s Secretary of State, Marco Rubio, Bosworth thinks there is still a good chance of policy lapsing into benign neglect as the new administration focuses elsewhere.

The wrong end of the telescope

What these and similar analyses share is a concern with problems of importance to the US, including domestic ones, and how they might be tackled by shifts in policy towards Latin America. They view the region from the end of a US-mounted telescope.

Trump’s approach may be the more brazen “America first!,” but the basic stance is much the same as these pundits. The different scenarios will be worked out in Washington, with Latin America’s future seen as shaped by how it handles US policy changes over which it has little influence. Analyses by these supposed experts are constrained by their adopting the same one-dimensional perspective as Washington’s, instead of questioning it.

Here’s one example. The word “neglect” is superficial because it hides the immense involvement of the US in Latin America even when it is “neglecting” it: from deep commercial ties to a massive military presence. It is also superficial because, in a real sense, the US constantly neglects the problems that concern most Latin Americans: low wages, inequality, being safe in the streets, the damaging effects of climate change, and many more. “Neglect” would be seen very differently on the streets of a Latin American city than it is inside the Washington beltway.

Who has the “drug problem”?

The vacuum in US thinking is nowhere more apparent than in responses to the drug problem. Trump threatens to declare Mexican drug cartels to be terrorist organizations and to invade Mexico to attack them.

But, as academic Carlos Pérez-Ricart told El Pais: “This is a problem that does not originate in Mexico. The source, the demand, and the vectors are not Mexican. It is them.” Mexican President Claudia Sheinbaum also points out that it is consumption in the US that drives drug production and trafficking in Mexico.

Trump could easily make the same mistake as his predecessor Clinton did two decades ago. Back then, billions were poured into “Plan Colombia” but still failed to solve the “drug problem,” while vastly augmenting violence and human rights violations in the target country.

A foretaste of what might happen, if Trump carries out his threat, occurred last July, when Biden’s administration captured Ismael “El Mayo” Zambada. That caused an all-out war between cartels in the Mexican state of Sinaloa.

Sheinbaum rightly turns questions about drug production and consumption back onto the US. Rhetorically, she asks: “Do you believe that fentanyl is not manufactured in the United States?…. Where are the drug cartels in the United States that distribute fentanyl in US cities? Where does the money from the sale of that fentanyl go in the United States?”

If Trump launches a war on cartels, he will not be the first US president to the treat drug consumption as a foreign issue rather than a concomitantly domestic one.

Where does the “migration problem” originate?

Trump is also not the first president to be obsessed by migration. Like drugs, it is seen as a problem to be solved by the countries where the migrants originate, while both the “push” and “pull” factors under US control receive less attention.

Exploitation of migrant labor, complex asylum procedures, and schemes such as “humanitarian parole” to encourage migration are downplayed as reasons. Biden intensified US sanctions on various Latin American countries, which have been shown conclusively to provoke massive emigration. Meanwhile Trump threatens to do the same.

Many Latin American countries have been made unsafe by crime linked to drugs or other problems in which the US is implicated. About 392,000 Mexicans were displaced as a result of conflict in 2023 alone, their problem aggravated by the massive, often illegal, export of firearms from the US to Mexico.

Costa Rica, historically a safe country, had a record 880 homicides in 2023, many of which were related to drug trafficking. In Brazil and other countries, US-trained security forces contribute directly to the violence, rather than reducing it.

Mass deportations from the US, promised by Trump, could worsen these problems, as happened in El Salvador in the late 1990s. They would also affect remittances sent home by migrant workers, exacerbating regional poverty. The threatened use of tariffs on exports to the US could also have serious consequences if Latin America does not stand up to Trump’s threats. Economist Michael Hudson argues that countries will have to jointly retaliate by refusing to pay dollar-based debts to bond holders if export earnings from the US are summarily cut.

China in the US “backyard”

Trump also joins the Washington consensus in its preoccupation with China’s influence in Latin America. Monica de Bolle is with the Peterson Institute for International Economics, a thinktank partly funded by Pentagon contractors. She told the BBC: “You have got the backyard of America engaging directly with China. That’s going to be problematic.”

Recently retired US Southern Command general, Laura Richardson, was probably the most senior frequent visitor on Washington’s behalf to Latin American capitals, during the Biden administration. She accused China of “playing the ‘long game’ with its development of dual-use sites and facilities throughout the region, “adding that those sites could serve as “points of future multi-domain access for the PLA [People’s Liberation Army] and strategic naval chokepoints.”

As Foreign Affairs points out, Latin America’s trade with China has “exploded” from $18 billion in 2002 to $480 billion in 2023. China is also investing in huge infrastructure projects, and seemingly its only political condition is a preference for a country to recognize China diplomatically (not Taiwan). Even here, China is not absolute as with Guatemala, Haiti, and Paraguay, which still recognize Taiwan. China still has direct investments in those holdouts, though relatively more modest than with regional countries that fully embrace its one-China policy.

Peru, currently a close US ally, has a new, Chinese-funded megaport at Chancay, opened in November by President Xi Jinping himself. Even right-wing Argentinian president Milei said of China, “They do not demand anything [in return].”

What does the US offer instead? While Antony Blinken proudly displayed old railcars that were gifted to Peru, the reality is that most US “aid” to Latin America is either aimed at “promoting democracy” (i.e. Washington’s political agenda) or is conditional or exploitative in other ways.

The BBC cites “seasoned observers” who believe that Washington is paying the price for “years of indifference” towards the region’s needs. Where the US sees a loss of strategic influence to China and to a lesser extent to Russia, Iran, and others, Latin American countries see opportunities for development and economic progress.

Remember the Monroe Doctrine

Those calling for a more “benign” policy are forgetting that, in the two centuries since President James Monroe announced the “doctrine,” later given his name, US policy towards Latin America has been aggressively self-interested.

Its troops have intervened thousands of times in the region and have occupied its countries on numerous occasions. Just since World War II, there have been around 50 significant interventions or coup attempts, beginning with Guatemala in 1954. The US has 76 military bases across the region, while other major powers like China and Russia have none.

The doctrine is very much alive. In Foreign Affairs, Brian Winter warns: “Many Republicans perceive these linkages [with China], and the growing Chinese presence in Latin America more broadly, as unacceptable violations of the Monroe Doctrine, the 201-year-old edict that the Western Hemisphere should be free of interference from outside powers.”

Bosworth adds that Trump wants Latin America to decisively choose a side in the US vs China scrimmage, not merely underplay the role of China in the hemisphere. Any country courting Trump, he suggests, “needs to show some anti-China vibes.”

Will Freeman is with the Council on Foreign Relations, whose major sponsors are also Pentagon contractors. He thinks that a new Monroe Doctrine and what he calls Trump’s “hardball” diplomacy may partially work, but only with northern Latin America countries, which are more dependent on US trade and other links.

Trump has two imperatives: while one is stifling China’s influence (e.g. by taking possession of the Panama Canal), another is gaining control of mineral resources (a reason for his wanting to acquire Greenland). The desire for mineral resources is not new, either. General Richardson gave an interview in 2023 to another defense-industry-funded thinktank in which she strongly insinuated that Latin American minerals rightly belong to the US.

Maintaining hegemonic power against the threat of multipolarity

Neoconservative Charles Krauthammer, writing 20 years ago for yet another thinktank funded by the  defense industry, openly endorsed the US’s status as the dominant hegemonic power and decried multilateralism, at least when not in US interests. “Multipolarity, yes, when there is no alternative,” he said. “But not when there is. Not when we have the unique imbalance of power that we enjoy today.”

Norwegian commentator Glen Diesen, writing in 2024, contends that the US is still fighting a battle – although perhaps now a losing one – against multipolarity and to retain its predominant status. Trump’s “America first!” is merely a more blatant expression of sentiments held by his other presidential predecessors for clinging on to Washington’s contested hegemony.

The irony of Biden’s presidency was that his pursuit of the Ukraine war has led to warmer relations between his two rivals, Russia and China. In this context, the growth of BRICS has been fostered – an explicitly multipolar, non-hegemonic partnership. As Glen Diesen says, “The war intensified the global decoupling from the West.”

Other steps to maintain US hegemony – its support for Israel’s genocide in Gaza, the regime-change operation in Syria and the breakdown of order in Haiti – suggest that, in Washington’s view, according to Diesen, “chaos is the only alternative to US global dominance.” Time and again, Yankee “beneficence” has meant ruination, not development.

These have further strengthened desires in the global south for alternatives to US dominance, not least in Latin America. Many of its countries (especially those vulnerable to tightening US sanctions) now want to follow the alternative of BRICS.

Unsurprisingly, Trump has been highly critical of this perceived erosion of hegemonic power on Biden’s watch. Thomas Fazi argues in UnHerd that this is realism on Trump’s part; he knows the Ukraine war cannot be conclusively won, and that China’s power is difficult to contain. Accordingly, this is leading to a “recalibrating of US priorities toward a more manageable ‘continental’ strategy — a new Monroe Doctrine — aimed at reasserting full hegemony over what it deems to be its natural sphere of influence, the Americas and the northern Atlantic,” stretching from Greenland and the Arctic to Tierra del Fuego and Antarctica.

The pundits may not agree on quite what Trump’s approach towards Latin America will be, but they concur with Winter’s judgment that the region “is about to become a priority for US foreign policy.” His appointment of Marco Rubio is a signal of this. The new secretary of state is a hawk, just like Blinken, but one with a dangerous focus on Latin America.

However, the mere fact that such pundits hark back to the Monroe Doctrine indicates that this is only, so to speak, old wine in new bottles. Even in the recent past, an aggressive application of the 201-year-old Monroe Doctrine has never seen a hiatus.

Recall US-backed coups that deposed Honduran President Manuel Zelaya (2009) and Bolivian Evo Morales (2019), plus the failed coup against Daniel Ortega in Nicaragua (2018), along with the parliamentary coup that ousted Paraguayan Fernando Lugo (2012). To these, US-backed regime change by “lawfare” included Dilma Rousseff in Brazil (2016) and Pedro Castillo in Peru (2023). Currently presidential elections have simply been suspended in Haiti and Peru with US backing.

Even if Trump is more blatant than his predecessors in making clear that his policymaking is based entirely on what he perceives to be US interests, rather than those of Latin Americans, this is not new.

As commentator Caitlin Johnstone points out, the main difference between Trump and his predecessors is that he “makes the US empire much more transparent and unhidden.” From the other end of the political spectrum, a former John McCain adviser echoes the same assessment: “there will likely be far more continuity between the two administrations than meets the eye.”

Regardless, Latin America will continue to struggle to set its own destiny, patchily and with setbacks, and this will likely draw it away from the hegemon, whatever the US does.

A deadly bird flu strain is headed for Australia – and First Nations people have the know-how to tackle it

Source: The Conversation (Au and NZ) – By Nell Reidy, Research Fellow, Monash Sustainable Development Institute, Monash University

ChameleonsEye/Shutterstock

A virulent strain of bird flu continues to spread across the world. Australia, New Zealand and Pacific nations are the only countries free from the infection, but this will no doubt change.

Known as “Highly Pathogenic Avian Influenza” or H5N1, the bird flu strain had killed more than 300 million birds worldwide as of December last year, including both poultry and wild bird populations.

Birds have always been part of the cultures and livelihoods of Australia Indigenous people. They feature in songs and dance, and are used for food and customary practices such as ceremonies and craft. Many of these practices continue today.

To date however, Indigenous peoples have not been adequately included in federal government planning for the arrival of H5N1.

So what is the likely result? Agencies and organisations will be ill-prepared to support Indigenous people experiencing intense social and cultural shock. And the opportunity to draw from the strengths of Indigenous organisations to tackle this impending disaster will have been squandered.

What is H5N1?

First identified in Hong Kong in 1997, H5N1 has since spread globally.

H5N1 is a viral infection primarily affecting birds – both poultry and wildlife. As overseas experience has shown, it can lead to population declines in wild birds and disrupt local ecosystems. Infected birds may exhibit symptoms such as lethargy, respiratory distress and neurological signs such as paralysis, seizures and tremors, and sudden death.

The virus also affects mammals including humans.
Since November 2003, more than 900 human cases have been reported across 24 countries. About half these people died.

While Australia has suffered several severe avian influenza epidemics since the 1970s, the H5N1 strain has not yet affected birds in Australia. But when it does, the damage may be profound.

Birds are vital to Indigenous culture

Australia’s diverse, unique bird population comprises about 850 species, 45% of which exist only in Australia.

Birds are highly significant to many Indigenous groups.

The adult magpie goose and its eggs, for example, are an important food source for groups in the Kakadu region.

In Tasmania, Indigenous groups are revitalising customary practices by harvesting mutton birds. And bird feathers are used by Indigenous artisans in fashion and jewellery-making.

If H5N1 makes birds sick and diminishes their populations, Indigenous people’s livelihoods and wellbeing – social, emotional, and spiritual – will be severely affected.

Many birds are already struggling

Of greatest concern are the fate of threatened and endangered bird species. Indeed, Australia’s Threatened Species Commissioner, Dr Fiona Fraser, has warned the forthcoming H5N1 event may be more ecologically devastating than the 2019–20 bushfires.

Migratory birds, such as waders that travel from Siberia to lake systems throughout Australia, may take years or decades to return – if they return at all.

Even relatively healthy bird populations, such as emus, may be at risk in areas where local populations are dwindling.

The challenge has become more pronounced following the 2019–20 bushfires that affected vast areas of Australia’s southeast. Biodiversity in these burnt forests was later found to have declined, especially in bird populations.

These challenges mean Australia’s native bird populations may struggle to remain healthy and sustainable, and their availability to Indigenous groups is likely to diminish.

Mobilising Indigenous know-how

Indigenous people are deeply engaged in caring for Country and caring for their communities. This makes them a strategic asset when planning for the arrival of H5N1.

For example, Indigenous rangers are deeply engaged in land and water management including habitat restoration and biodiversity surveys. So, they are well placed to protect and monitor native species.

Traditional Owners and Indigenous rangers manage 87 dedicated “Indigenous Protected Areas” covering 90 million hectares of land and six million hectares of sea.

Indigenous health organisations will also be crucial to identifying human illness, should rare animal-to-human transmissions occur.

Shire councils and land councils are also well-placed to identify and monitor the impacts of bird flu.

It’s time for Indigenous inclusion

Indigenous inclusion in the federal government’s response to the threat H5N1 has been late and inadequate

This means Australia is already behind in supporting Indigenous groups to understand the threat and how to respond if they observe it – including how to deal with sick or dead birds.

To fill these gaps in public information, National Indigenous Disaster Resilience at Monash University has produced a bird flu fact sheet.

Indigenous community organisations demonstrated an extraordinary capacity for leadership during COVID-19. The muscle memory to mobilise in response to another outbreak remains strong.

Indigenous groups must be centred in preparing and responding to H5N1. What’s more, Indigenous culture needs to be foregrounded when considering how the virus might affect the social, psychological, spiritual, and economic wellbeing of communities.


In response to concerns raised in this article, a spokesperson for the Department of Agriculture, Fisheries and Forestry said the federal government was “working to engage with First Nations communities to ensure we meet community needs” before and during an outbreak of H5N1.

The department’s Northern Australia Quarantine Strategy was surveilling for avian influenza in northern Australia, including working with Indigenous Rangers. Indigenous engagement has also included presentations delivered virtually and on-country.

“By fostering close partnerships with First Nations communities and Indigenous rangers, and leveraging access to a broad collaborative network, NAQS is able to facilitate trusted avenues for First Nations communities and Indigenous rangers to report concerns about wild bird health across northern Australia,” the spokesperson said.

States and territories were planning local responses, and nationally coordinated, culturally appropriate communication activities were being developed. The spokesperson said Parks Australia was also working with Traditional Owners at jointly managed national parks, and with the Indigenous Protected Areas network, in developing plans to prepare and respond to any H5N1 detection.

Mastercard plans to get rid of credit card numbers. We could be heading towards the end of cards

Source: The Conversation (Au and NZ) – By Gary Mortimer, Professor of Marketing and Consumer Behaviour, Queensland University of Technology

Antonina St/Shutterstock

Mastercard has announced plans to remove the 16-digit number from their credit and debit cards by 2030 in a move designed to stamp out identity theft and fraudulent use of cards.

The numbers currently used to identify cards will be replaced with tokenisation and biometric authentication

In 2022, Mastercard added biometric options enabling payments to be made with a smile or wave of the hand.

Tokenisation converts the 16-digit card number into a different number – or token – stored on your device, so card information is never shared when you tap your card or phone or make payments online.

The first rollout of these numberless cards will be through a partnership with AMP Bank, but it is expected other banks will follow in the coming 12 months.

Why card security is important

There is nothing quite like the sinking feeling after receiving a call or text from your bank asking about the legitimacy of a card transaction.

In 2023-2024 the total value of card fraud in Australia was A$868 million, up from $677.5 million the previous financial year.

Credit card numbers and payment details are often exposed in major data breaches affecting large and small businesses.

Late last year, the US Federal Trade Commission took action against the Marriott and Starwood Hotels for lax data security. More than 300 million customers worldwide were affected.

Event ticketing company Ticketmaster was also hacked last year. The details of several hundred million customers, including names, addresses, credit card numbers, phone numbers and payment details were illegally accessed.

So-called “card-not-present fraud”, where an offender processes an unauthorised transaction without having the card in their physical possession, accounts for 92% of all card fraud in Australia. This rose 29% in the last financial year.

The Card Verification Value (CVV) (or three-digit number on the back of a credit card) aimed to ensure the person making the transaction had the physical card in their hands. But it is clearly ineffective.

Benefits of removing credit card numbers

Removing the credit card number is the latest attempt to curb fraud. Removing numbers stops fraudsters processing unauthorised card-not-present transactions.

It also reduces the potential for financial damage of victims exposed in data breaches, if organisations are no longer able to store these payment details.

The storage of personal information is a contested issue. For example, the 2022 Optus data breach exposed information from customers who had previously held accounts with the telco back in 2018.

Removing the ability of organisations to store payment details in the first place, removes the risk of this information being exposed in any future attack.

While any efforts to reduce fraud are welcome, this new approach raises some new issues to consider.

Potential problems with the new system

Mastercard has said customers will use tokens generated by the customer’s banking app or biometric authentication instead of card numbers.

This is likely to be an easy transition for customers who use mobile banking.

However, the use of digital banking is not universal. Many senior consumers and those with a disability don’t use digital banking services. They would be excluded from the new protections.

While strengthening the security attached to credit cards, removing numbers shifts the vulnerability to mobile phones and telecommunication providers.

Offenders already access victims’ phones through mobile porting and impersonation scams. These attacks are likely to escalate as new ways to exploit potential vulnerabilities are found.

There are also concerns about biometrics. Unlike credit card details, which can be replaced when exposed in a data breach, biometrics are fixed. Shifting a focus to biometrics will increase the attractiveness of this data, and potentially opens victims up to ongoing, irreversible damage.

While not as common, breaches of biometric data do occur.

For example, web-based security platform BioStar 2 in the UK exposed the fingerprints and facial recognition details of over one million people. Closer to home, IT provider to entertainment companies Outabox is alleged to have exposed facial recognition data of more than one million Australians.

Will we really need cards in the future?

While removing the numbers may reduce credit card fraud, emerging smart retail technologies may remove the need for cards all together.

Smartphone payments are already becoming the norm, removing the need for physical cards. GlobalData revealed a 58% growth in mobile wallet payments in Australia in 2023, to $146.9 billion. In October 2024, 44% of payments were “device-present” transactions.

Amazon’s innovative “Just-Walk-Out” technology has also removed the need for consumers to bring a physical credit or debit card all together.

Amazon Go and the world’s most advanced shopping technology.

This technology is available at more than 70 Amazon-owned stores, and at more than 85 third-party locations across the US, UK, and Australia. These include sports stadiums, airports, grocery stores, convenience stores and college campuses.

The technology uses cameras, weight sensors and a combination of advanced AI technologies to enable shoppers in physical stores make purchases without having to swipe or tap their cards at the checkout line.

Such technology is now being offered by a variety of other vendors including Trigo, Cognizant and Grabango. It is also being trialled across other international retailers, including supermarket chains Tesco and ALDI.

While Just-Walk-Out removes the need to carry a physical card, at some point consumers still need to enter their cards details into an app. So, to avoid cards and numbers completely, smart retail tech providers are moving to biometric alternatives, like facial recognition payments.

Considering the speed at which smart retail and payment technology is entering the marketplace, it is likely physical credit cards, numberless or not, will soon become redundant, replaced by biometric payment options.

Should Australia mandate cancer warnings for alcoholic drinks?

Source: The Conversation (Au and NZ) – By Rachel Visontay, Postdoctoral Research Fellow in Alcohol and Long-term Health, University of Sydney

Hryshchyshen Serhii/Shutterstock

Alcohol causes huge harm in Australia, responsible for 5,800 new cancer cases per year. Yet many of us remain in the dark about its health risks.

In January, the United States’ Office of the Surgeon General, the country’s leading public health spokesperson, recommended warnings about alcohol’s cancer risks should be displayed on drink packaging.

These messages have already been made obligatory in Ireland and South Korea.

So, do they work? And should we mandate them here?

Isn’t a glass of wine or two good for me?

Most of us know heavy drinking is unhealthy.

Yet the belief a few glasses of wine helps protect against heart disease and other conditions has persisted. That is despite evidence in recent years showing the benefits have been overestimated and the harms underplayed.

In fact, any level of alcohol use increases the risk for several types of cancer, including colorectal cancer (affecting the large intestine and rectum) and breast cancer.

In recent years, the evidence has strengthened showing alcohol plays a clear, causal role increasing cancer risk and other serious health problems, as well as all-cause mortality.

One study estimated how many new cancer cases will develop across the lifetimes of the 18.8 million Australian adults who were alive in 2016. It predicted a quarter of a million (249,700) new cancers – mostly colorectal – will arise due to alcohol.

We know what causes this harm. For example, acetaldehyde – a chemical produced by the body when it processes alcohol – is carcinogenic.

Alcohol also increases cancer risk through “oxidative stress”, an imbalance in the body’s antioxidants and free radicals which causes damage to DNA and inflammation.

It can also affect hormone levels, which raises the risk for breast cancer in particular.

Australians unaware of the risk

While the harms are well-known to researchers, many Australians remain unaware.

Figures vary, but at best only 59% of us know about the direct link between alcohol and cancer (and at worst, just one in five are aware).

Perhaps the best evidence this message has failed to sink in is our continued love affair with alcohol.

In 2022–23 69% of us drank alcohol, with one in three doing so at levels deemed risky by the National Health and Medical Research Council. For both men and women, that means having more than ten standard drinks per week or more than four in one day.

What are other countries doing?

Like Australia, the US already has warnings on alcohol about its impacts on unborn children and a person’s ability to operate cars and machinery.

The US Surgeon General wants additional explicit warnings about cancer risk to be compulsory.

This follows Ireland, the first country to mandate cancer labels for alcohol. From 2026, alcohol packaging will include the warning: “there is a direct link between alcohol and fatal cancers”.

Other countries, including Norway and Thailand, are also reportedly investigating cancer warning labels.

Since 2017, alcohol producers in South Korea have had to choose between three compulsory warning labels – two of which warn of cancer risks. However they can instead opt for a label which warns about alcohol’s risks for dementia, stroke and memory loss.

Will Australia follow suit?

Australian health bodies have been advocating for cancer warnings on drink packaging for over a decade.

Currently, whether to include warnings about alcohol’s general health risks is at the discretion of the manufacturer.

Many use vague “drink responsibly” messages or templates provided by DrinkWise, an organisation funded by the alcohol industry.

Pregnancy warning labels (“Alcohol can cause lifelong harm to your baby”) only became obligatory in 2023. Although this covers just one of alcohol’s established health effects, it has set an important precedent.

We now have a template for how introducing cancer and other health warnings might work.

With pregnancy labels, the government consulted public health and industry bodies and gave a three-year transition period for manufacturers to adjust. We even have examples of colour and formatting of required labels that could be adapted.

Perhaps most promisingly, four in five surveyed Australians support adding these cancer-specific warnings.

Cancer warnings already feature on some tobacco products in Australia.
Galexia/Shutterstock

Would it work?

We know the existing “drink responsibly”-style warnings are not enough. Research shows consumers find these messages ambiguous.

But would warnings about cancer be an improvement? Ireland’s rules are yet to come into effect, and it’s too early to tell how well South Korea’s policy has worked (there are also limitations give manufacturers can choose a warning not related to cancer).

But a trial of cancer warnings in one Canadian liquor store found they increased knowledge of the alcohol–cancer link by 10% among store customers.

Cancer messages would likely increase awareness about risks. But more than that – a 2016 study that tested cancer warnings on a group of 1,680 adults across Australia found they were also effective at reducing people’s intentions to drink.

The evidence suggests a similar policy could replicate the success of cancer warnings on cigarette packaging – first introduced in the 1970s – at increasing knowledge about risks and reducing consumption. Smoking rates in Australian adults have declined steadily since these warnings were first introduced.

It may take years before Australia changes its rules on alcohol labelling.

In the meantime, it’s important to familiarise yourself with the current national low-risk drinking guidelines, which aim to minimise harm from alcohol across a range of health conditions.

This year, make a commitment to understanding your world better: practise the art of slow looking

Source: The Conversation (Au and NZ) – By Sienna van Rossum, PhD Candidate, Queensland College of Art and Design, Griffith University

gilber franco/Unsplash

We are in a rapidly changing visual culture where it is increasingly inadequate to take images at face value.

There is an ever-increasing prevalence of image manipulation and AI imagery. And in the attention economy, our attention has become a precious, sought-after resource. Images participate in this redirection of our attention with an endless production line of new, stimulating content to maximise user engagement.

In this environment, there is an increasing demand to prioritise visual literacy with the same rigour as we do with writing and reading.

We need to look more closely at images – to practise slow looking.

What is it you’re looking at?

The act of slow looking involves taking a pause and thoroughly describing what you see.

Often, we jump to the image’s meaning by identifying its contents. But it is important to discern what the image actually “looks like” and how this influences its reading.

The aim of looking slowly is not just to verify what is real, fake or AI. After all, there will become a time when it is too difficult and time-consuming for the average person to determine every AI-generated image without a watermark or label.

While the ability to detect whether something is AI is one important skill, this should not be the only reason to practise slow looking. To only determine if it is fake or real can ignore what an AI image can also tell us about our cultural climate.

In December, Madonna shared a deepfake of her embracing the Pope from digital artist RickDick.

Satirical images of the pope have a long history. As early as the 16th century, artists depicted the head of the Catholic Church alongside the profane as a means of critique and provocation.

RickDick’s deepfakes, in their eerie sense of realness, prove a new means to continue to satirise and provoke viewers in the digital age. We can deduce on close inspection that these images of Madonna and the Pope are not real photographs, but we can look even further to also discern what nevertheless gives these AI images their potency.

Fake or not, the lifelike, intimate embrace of the two icons probes an old but ongoing friction between perceived acts of blasphemy in pop culture and the sacred authority of the church.

In this etching from 1555, the Pope has three heads: one wears the papal tiara, one wears a turban, and one is an infant.
The Metropolitan Museum of Art

The act of slow looking develops visual literacy. It examines why certain images go viral, why some move us above others and what they say about our reality, values or beliefs.

Beginning to look slowly

To begin this practice, imagine you are trying to describe an image to a friend who cannot see it. What’s happening in the image? What is its scale? What colours are used? How is it made? Where and how are you viewing it – on your phone, a billboard or poster?

Adopt a questioning stance to spot possible biases or blind spots – your own, or of the creator of the image. What is possibly missing from the image? Whose perspective is it or isn’t it showing?

This process can be significantly enhanced through using your hands: draw or paint what you see. It doesn’t need to be expensive or time-consuming. Nor do you need to be “good” at it. Drawing on a scrap piece of paper with an old ballpoint pen you have on your desk for even just a few minutes can connect the mind and body into a deep awareness of your visual field.

Try drawing what you see, to really examine it and have a deeper connection with it.
Eepeng Cheong/Unsplash

Pick anything to draw from your immediate surroundings or screens. This is all about the process: it is not the goal to have a finished artwork.

Key details that weren’t apparent before will emerge through this creative practice and help you analyse how an image works, why it is or isn’t engaging and what are its multiple possible meanings.

Slowing down

That we should look more slowly in our fast-paced, oversaturated visual culture is not a new concept, especially in the art community.

Numerous galleries such as London’s Tate Gallery, the National Gallery of Australia , and most recently Ipswich Art Gallery’s 2024 Arriving Slowly exhibition host “slow looking” events to initiate this practice.

These events often take the form of a guided tour and provide prompts to build the viewer’s analytical skills, with the additional benefit of building a communal engagement to look slowly together.

We are all creators and consumers of images. It is important for all of us to reflect on where our attention is being directed, and why, in the constant flood of images.

We have a shared responsibility in how we examine images. Now, more than ever, our visual literacy would benefit from creative practices to slow us down. At both individual and collective levels, we should prioritise looking intently at how our images remember the past, define our present, and envision the future.

Books of mana: 10 essential reads for Waitangi Day

Source: The Conversation (Au and NZ) – By Angela Wanhalla, Professor of History, University of Otago

In the 185 years since te Tiriti o Waitangi was signed between Māori rangatira and the British Crown, Māori have been writing about its meaning, sharing their stories and seeking justice.

For some years, we have been reading and thinking about this mass of written work by Māori. While we know and love these titles, we were aware many New Zealanders have little idea that Māori scholarship stretches back to the earliest books published in this country.

So, in 2018 we collaborated with Ngā Pae o te Māramatanga (the Māori Centre of Research Excellence) and Te Apārangi Royal Society of New Zealand to curate a list of Māori non-fiction publications. Our list formed the inspiration for Books of Mana: 180 Māori-Authored Books of Significance, published this week by Otago University Press.

Co-edited with Jeanette Wikaira, and featuring short essays by leading Māori writers about their relationship to books, mātauranga Māori and the written word, it showcases 180 Māori-authored books published between 1815 and 2022.

For generations our ancestors created sense, meaning, stories and histories from the mountains, rivers and coastlines, and recited generations of history and knowledge through whakapapa, karanga, whaikōrero, mōteatea and pūrākau.

With the arrival of Europeans in the late 18th-century, Māori adopted new tools for recording and passing on knowledge. Pen and paper were rapidly added to the kete and used to weave stories, to engage in creative expression, and as a way to connect and resist.

Much of this writing holds prestige, authority, power, influence, status and even charisma. The word that we think best describes these books is mana.

We encourage all New Zealanders to know more about these remarkable books. At a time when Māori language, culture, identity and te Tiriti are politically threatened, Māori writing is essential for anyone serious about understanding the past, present and future of Aotearoa New Zealand from a Māori perspective.

This Waitangi Day, consider reading any one of these 180 books. But to help make the selection even easier, here are ten that are accessible in bookstores or local libraries.

These titles address language revitalisation, leadership, politics and history. They are also relevant to the world we find ourselves in today.


Ngā Pepa a Ranginui, The Walker Papers – Ranginui Walker

To understand contemporary political debates it is worth looking to the past. Ranginui Walker was one of New Zealand’s leading intellectuals. His collection of opinion pieces, originally published in the Listener magazine between 1973 and 1990, are collated in Ngā Pepa a Ranginui, The Walker Papers.

All of these opinion pieces remain relevant today. As a communicator between the worldviews of Māori and Pākehā, the range of topics he wrote about was extraordinary, from fishing rights, to Māori ideas about health, to critiques of government policies.


Tōku Reo, Tōku Ohooho – Chris Winitana

Ranginui Walker said te reo Māori is a taonga. In Tōku Reo Tōku Ohooho, Chris Winitana tells the story of the people who fought for its retention and revitalisation from the 1970s – and why this kaupapa remains so vitally important today. The book is available either in English or te reo Māori and will be of interest to many as we strive to keep te reo Māori alive.


Huia Histories of Māori: Ngā Tāhuhu Kōrero – Danny Keenan

A stellar lineup of Māori writers will help deepen your knowledge of custom, the natural world, language, health, politics and cultural expression in editor Danny Keenan’s recently republished book Huia Histories of Māori. It covers a vast array of topics, from waka migration traditions, to the introduction of Christianity, to the New Zealand Wars and much more.


Navigating the Stars: Maori Creation Myths – Witi Ihimaera

In Navigating the Stars: Māori creation myths Witi Ihimaera shows how we have always been storytellers, intellectuals and knowledge makers. Pūrākau (legends) are retold for the 21st-century by this pioneer of the Māori novel and short story.

We are in awe of the way the author honours this storytelling tradition and strengthens it for the future. This is a big book that starts our national history with Māori creation narratives, and challenges us to think differently about our past.


Te Kōparapara: An introduction to the Māori world – Michael Reilly & others

If you are looking to build your knowledge of te ao Māori (the Māori world), but don’t know where to begin, we recommend Te Kōparapara. It’s a really accessible introduction to Māori culture, tikanga, history and contemporary society.


Wayfinding Leadership – Chellie Spiller, Hoturoa Barclay-Kerr & John Panoho

Our tūpuna (ancestors) guide us into the future. Chellie Spiller, Hoturoa Barclay-Kerr and John Panoho look to waka navigators in Wayfinding Leadership. It’s part practical guide about how to lead for the collective good, but also part introduction to Māori philosophy. And it’s all cleverly told through the boldness, radical vision and skill of those who laid the foundations for Māori to flourish in these islands.


Imagining Decolonisation – Bianca Elkington, Moana Jackson & others

The bestselling Imagining Decolonisation explains what decolonisation looks like for Māori and Pākehā in an accessible way, and sets out what is required for our country to become a just society.

A particular highlight is the contribution of the late Moana Jackson. A lawyer who was passionate about the transformative possibilities of te Tiriti for Aotearoa, his writings about justice reform and constitutional change will continue to shape generations to come.


A Fire in the Belly of Hineāmaru – Melinda Webber & Te Kapua O’Connor

A Fire in the Belly of Hineāmaru: A collection of narratives about Te Tai Tokerau, translated into te reo Māori by Quinton Hita, is an invitation into Te Tai Tokerau histories, lands and esteemed ancestors, told through the lives of peacemakers, strategists, explorers and entrepreneurs (available in both English and te reo Māori editions).


Mokorua – Ariana Tikao

Mokorua is an inspiring account of the author “re-indigenising” through receiving her moko kauae. We love how she weaves that story into a personal reclaiming of language and identity. Matt Calman’s photographs are particularly striking, too.


From the Centre: A writer’s life – Patricia Grace

A favourite book is From the Centre: a writer’s life, an uplifting memoir by one of our most gifted fiction writers. It stresses the power of reading for cultivating imagination, anchoring identity and deepening a sense of belonging.

We treasured reading about Grace’s life growing up, how she responded to instances of injustice and unfairness, and how she had the courage to write about everyday Māori families. The gentle weight of this beautiful work, in both a physical and emotional sense, will live with us for a long time.


These books enrich our scholarship and our everyday life. We hope you take some time this Waitangi week to engage with Māori writing, and that you come to love these taonga as much as we do.

Trump’s Project 2025 agenda caps decades-long resistance to 20th century progressive reform

Source: The Conversation (Au and NZ) – By Colin Gordon, Professor of History, University of Iowa

There has long been a tug-of-war over White House plans to make government more liberal or more conservative. Douglas Rissing/iStock / Getty Images Plus

For much of the 20th century, efforts to remake government were driven by a progressive desire to make the government work for regular Americans, including the New Deal and the Great Society reforms.

But they also met a conservative backlash seeking to rein back government as a source of security for working Americans and realign it with the interests of private business. That backlash is the central thread of the Heritage Foundation’s “Project 2025” blueprint for a second Trump Administration.

Alternatively disavowed and embraced by President Donald Trump during his 2024 campaign, Project 2025 is a collection of conservative policy proposals – many written by veterans of his first administration. It echoes similar projects, both liberal and conservative, setting out a bold agenda for a new administration.

But Project 2025 does so with particular detail and urgency, hoping to galvanize dramatic change before the midterm elections in 2026. As its foreword warns: “Conservatives have just two years and one shot to get this right.”

The standard for a transformational “100 days” – a much-used reference point for evaluating an administration – belongs to the first administration of Franklin D. Roosevelt.

Social reforms and FDR

In 1933, in the depths of the Great Depression, Roosevelt faced a nation in which business activity had stalled, nearly a third of the workforce was unemployed, and economic misery and unrest were widespread.

But Roosevelt’s so-called “New Deal” unfolded less as a grand plan to combat the Depression than as a scramble of policy experimentation.

Roosevelt did not campaign on what would become the New Deal’s singular achievements, which included expansive relief programs, subsidies for farmers, financial reforms, the Social Security system, the minimum wage and federal protection of workers’ rights.

Those achievements came haltingly after two years of frustrated or ineffective policymaking. And those achievements rested less on Roosevelt’s political vision than on the political mobilization and demands made by American workers.

A generation later, another wave of social reforms unfolded in similar fashion. This time it was not general economic misery that spurred actions, but the persistence of inequality – especially racial inequality – in an otherwise prosperous time.

LBJ’s Great Society

President Lyndon B. Johnson’s Great Society programs declared a war on poverty and, toward that end, introduced a raft of new federal initiatives in urban, education and civil rights.

These included the provision of medical care for the poor and older people via Medicaid and Medicare, a dramatic expansion of federal aid for K-12 education, and landmark voting rights and civil rights legislation.

As with the New Deal, the substance of these policies rested less with national policy designs than with the aspirations and mobilization of the era’s social movements.

Resistance to policy change

Since the 1930s, conservative policy agendas have largely taken the form of reactions to the New Deal and the Great Society.

The central message has routinely been that “big government” has overstepped its bounds and trampled individual rights, and that the architects of those reforms are not just misguided but treasonous. Project 2025, in this respect, promises not just a political right turn but to “defeat the anti-American left.”

After the 1946 midterm elections, congressional Republicans struck back at the New Deal. Drawing on business opposition to the New Deal, popular discontent with postwar inflation, and common cause with Southern Democrats, they stemmed efforts to expand the New Deal, gutting a full employment proposal and defeating national health insurance.

They struck back at organized labor with the 1947 Taft-Hartley Act, which undercut federal law by allowing states to pass anti-union “right to work” laws. And they launched an infamous anti-communist purge of the civil service, which forced nearly 15,000 people out of government jobs.

In 1971, the U.S. Chamber of Commerce commissioned Lewis Powell – who would be appointed by Republican President Richard Nixon to the Supreme Court the next year – to assess the political landscape. Powell’s memorandum characterized the political climate at the dawn of the 1970s – including both Great Society programs and the anti-war and Civil Rights movements of the 1960s – as nothing less than an “attack on the free enterprise system.”

In a preview of current U.S. politics, Powell’s memorandum devoted special attention to a disquieting “chorus of criticism” coming from “the perfectly respectable elements of society: from the college campus, the pulpit, the media, the intellectual and literary journals, the arts and sciences, and from politicians.”

Powell characterized the social policies of the New Deal and Great Society as “socialism or some sort of statism” and advocated the elevation of business interests and business priorities to the center of American political life.

Building a conservative infrastructure

Powell captured the conservative zeitgeist at the onset of what would become a long and decisive right turn in American politics. More importantly, it helped galvanize the creation of a conservative infrastructure – in the courts, in the policy world, in universities and in the media – to push back against that “chorus of criticism.”

This political shift would yield an array of organizations and initiatives, including the political mobilization of business, best represented by the emergence of the Koch brothers and the powerful libertarian conservative political advocacy group they founded, known as Americans for Prosperity. It also yielded a new wave of conservative voices on radio and television and a raft of right-wing policy shops and think tanks – including the Heritage Foundation, creator of Project 2025.

In national politics, the conservative resurgence achieved full expression in President Ronald Reagan’s 1980 campaign. The “Reagan Revolution” united economic and social conservatives around the central goal of dismantling what was left of the New Deal and Great Society.

Powell’s triumph was evident across the policy landscape. Reagan gutted social programs, declared war on organized labor, pared back economic and social regulations – or declined to enforce them – and slashed taxes on business and the wealthy.

Publicly, the Reagan administration argued that tax cuts would pay for themselves, with the lower rates offset by economic growth. Privately, it didn’t matter: Either growth would sustain revenues, or the resulting budgetary hole could be used to “starve the beast” and justify further program cuts.

Reagan’s vision, and its shaky fiscal logic, were reasserted in the “Contract with America” proposed by congressional Republicans after their gains in the 1994 midterm elections.

This declaration of principles proposed deep cuts to social programs alongside tax breaks for business. It was perhaps most notable for encouraging the Clinton administration to pass the Personal Responsibility and Work Opportunity Act of 1996, “ending welfare as we know it,” as Clinton promised.

Aiming at the ‘deep state’

Project 2025, the latest in this series of blueprints for dramatic change, draws most deeply on two of those plans.

As in the congressional purges of 1940s, it takes aim not just at policy but at the civil servants – Trump’s “deep state” – who administer it.

In the wake of World War II, the charge was that feckless bureaucrats served Soviet masters. Today, Project 2025 aims to “bring the Administrative State to heel, and in the process defang and defund the woke culture warriors who have infiltrated every last institution in America.”

As in the 1971 Powell memorandum, Project 2025 promises to mobilize business power; to “champion the dynamic genius of free enterprise against the grim miseries of elite-directed socialism.”

Whatever their source – party platforms, congressional bomb-throwers, think tanks, private interests – the success or failure of these blueprints rested not on their vision or popular appeal but on the political power that accompanied them. The New Deal and Great Society gained momentum and meaning from the social movements that shaped their agendas and held them to account.

The lineage of conservative responses has been largely an assertion of business power. Whatever populist trappings the second Trump administration may possess, the bottom line of the conservative cultural and political agenda in 2025 is to dismantle what is left of the New Deal or the Great Society, and to defend unfettered “free enterprise” against critics and alternatives.

Troubled road in New Caledonia fully reopens after eight-month closure

By Patrick Decloitre, RNZ Pacific correspondent French Pacific desk

The main provincial road linking New Caledonia’s capital, Nouméa, to the south of the main island will be fully reopened to motorists after almost eight months.

Route Provinciale 1 (RP1), which passes through Saint Louis, had been the scene of violent acts — theft, assault, carjackings — against passing motorists and deemed too dangerous to remain open to the public.

Instead, since the violent riots that started in mid-May 2024, residents of nearby Mont-Dore had to take special sea ferries to travel to Nouméa, while police and gendarmes gradually organised protected convoys at specific hours.

The rest of the time, motorists and pedestrians were “filtered” by law enforcement officers, with two “locks” located at each side of the Saint Louis village.

The troubled road was even fully closed to traffic in July 2024 after tensions and violence in Saint Louis peaked.

Last Friday, January 31, French High Commissioner Louis Le Franc announced that the RP1 would be fully reopened to traffic from today.

Gendarme patrols stay
The French High Commission, however, stressed that the law enforcement setup and gendarme patrols would remain posted “as long as it takes to ensure everyone’s safety”.

“Should any problem arise, the high commission reserves the right to immediately reduce traffic hours,” a media release warned.

The RP1’s reopening coincides with the beginning, this week, of crucial talks in Paris between pro-independence, pro-France camps and the French state on New Caledonia’s political future status.

Labor’s dumping of Australia’s new nature laws means the environment is shaping as a key 2025 election issue

Source: The Conversation (Au and NZ) – By Peter Burnett, Honorary Associate Professor, ANU College of Law, Australian National University

Controversy over land clearing at the Lee Point (Binybara) housing development site, near Darwin, highlights the urgent need for environmental law reform. Euan Ritchie

Prime Minister Anthony Albanese has shelved the proposed reforms to Australia’s 25-year-old environment laws, citing a lack of parliamentary support for the changes.

The decision breaks Labor’s 2022 election commitment to overhaul the protections. The Albanese government is now the latest in a string of governments that have tried and failed to reform the law known formally as the Environmental Protection and Biodiversity Conservation (EPBC) Act.

This is despite two major independent reviews calling for wholesale change.

Labor’s capitulation does not, however, change the facts. Australia’s natural environment is deteriorating rapidly. Laws are urgently needed to protect our nation’s valuable natural assets.

Establishing effective laws is an investment that will benefit Australia’s biodiversity, economy, cultural values, health and wellbeing. Nature is now a key 2025 election issue.

How did we get here?

An independent review of the EPBC Act, known as the Samuel Review, was completed in 2020 under the former Coalition government. It found that without urgent changes, most of Australia’s threatened plants, animals and ecosystems will become extinct.

Federal Environment Minister Tanya Plibersek promised to act on the review’s recommendations, via a plan Labor badged as “Nature Positive”.

The centrepiece of reform is to set national environmental standards that would be overseen by an independent regulator and watchdog called Environmental Protection Australia (EPA). But reform was split into three stages.

Stage one legislated for national markets in nature repair and expanded the requirement to assess potential impacts on water resources under the EPBC Act. The so-called “water trigger” now captures “unconventional gas” projects such as shale gas recovery in the Northern Territory’s Beetaloo Basin. The law passed in December 2023, but the markets are not yet functioning.

Stage two of the reforms, including establishing a federal EPA, came before the Senate in late 2024. Plibersek had reportedly made a deal with the crossbench to secure passage. But this deal was scuttled by Albanese at the eleventh hour.

Stage two was relisted for discussion in the upcoming first parliamentary sitting week of 2025, this week. But on Saturday, Albanese told The Conversation the government would, again, not be proceeding with the reform this term.

The reforms have been delayed for so long that we are now closer to the next statutory review of the laws, due in 2029, than to the last one.

Stage three, which covers the bulk of substantive reform recommended in the Samuel Review, is yet to be seen publicly.

What will happen after the next election?

Albanese must go to the polls by May 17, but there is speculation the election may be as early as March. So what is the likely fate of these environmental reforms in the next term?

A Roy Morgan poll on Monday found if a federal election were held now, the result would be a hung parliament. So the result is looking tight.

Government control of the Senate is rare. So whoever is in power after the election is very likely to rely on crossbench support for any reforms.

Albanese has ruled out forming a coalition with the Greens or crossbenchers in the event of a hung parliament. However, Opposition Leader Peter Dutton says he would negotiate with independents to form government.

A returned Albanese majority government would probably revisit the scuttled deal on stage two. With elections in the rear-view mirror, Albanese may be prepared to wear some political pain early in the next term to secure a deal. He would also still need to roll out the bulk of the Nature Positive reforms, the detail of which remains hidden behind a vague “stage three” banner.

A minority Albanese government may face a tougher ask: demands from an environmentally progressive crossbench for major commitments to environmental reform in return for promises of support on budget and confidence.

A Coalition government would be coming from a very different angle. Dutton has painted Nature Positive as a
disaster” for the economy, expressing particular concern about impacts on the mining sector.

The Coalition’s environmental agenda is increasingly focused on “cutting green tape” – in other words, reducing bureaucratic hurdles for developers – and repealing bans on nuclear power stations. Finding crossbench support in the Senate for this agenda could be challenging.

The Greens have vowed to make environmental protection a key election issue, urging voters to cast their ballot for nature this election.

A recent poll published by the Biodiversity Council shows 75% of Australians support strengthening national environmental law to protect nature. Only 4% are opposed and the rest are undecided.

But converting a high level of broad support into votes is another thing altogether – especially during a cost-of-living crisis.

Crystal clear consequences

The political crystal ball remains cloudy. But when it comes to the state of Australia’s environment, the picture is clear.

The environment continues to decline and the consequences are increasingly serious. These consequences extend beyond further irreversible loss and the increasing cost of environmental repair, to include the economic and social consequences of losing more of the natural assets on which our quality of life depends.

The building blocks of successful reform are all on the table, where the Samuel Review put them in 2020.

When will governments accept that kicking the can down the road is selling us all down the drain?

Sir Collin Tukuitonga criticises RFK Jr’s measles claims, slams health misinformation

By Susana Suisuiki, RNZ Pacific Waves presenter/producer

The chair of a World Health Organisation (WHO) advisory group is urging world leaders to denounce misinformation around health.

Sir Collin Tukuitonga is reacting to comments made by US Senator Robert F Kennedy, who claimed that measles was not the cause of 83 deaths in Samoa during a measles outbreak there in 2019.

Samoa’s Head of Health Dr Alec Ekeroma rejected Kennedy’s claim, calling it a “complete lie”.

Speaking to RNZ Pacific Waves, Sir Collin said leaders had a duty to protect people from inaccurate public health statements.

He said he was “absolutely horrified” that the person who “is the most influential individual in the US health system” could “tell lies and keep a straight face”.

“But [I am] not surprised because Kennedy has a history of subscribing to fringe, incorrect knowledge, conspiracy theories, and odd things of that type.”

He said Dr Ekeroma was very clear and direct in his condemnation of the lies from Kennedy and the group.

‘Call it for what it is’
“I encourage all of our people who are in a position to call these people for what it is.”

Sir Collin is the chair of the WHO’s Strategic and Technical Advisory Group on the Prevention and Control of Noncommunicable Diseases.

He said Kennedy’s comments and attitude toward vaccination will feed the anti-vaxxers and and discourage parents who might be uncertain about vaccines.

“So, [it is] potentially going to have a negative impact on immunisation programmes the world over. The United States has a significant influence on global health policy.

“These kinds of proclamations and attitudes and ideologies will have disastrous consequences.”

He believes that the scientific community should speak up, adding that political and business leaders in the region should also condemn such behaviour.

Withdrawal of US from WHO
Sir Collin described President Donald Trump’s decision to pull the US out of the WHO as “dangerous”.

He said Washington is a major contributor to the money needed by WHO, which works to protect world health, especially vulnerable communities in developing countries.

“I understand they contribute about a fifth of the WHO budget,” he said.

“The United States is a world leader in the technical, scientific expertise in a number of areas, that may not be as available to the rest of the world.

“Research and development of new medicines and new treatments, a large chunk of which originates in the United States.

“The United States falling out of the chain of surveillance and reporting of global outbreaks, like Covid-19, puts the whole world at risk.”

He added there were ‘a good number of reasons” why the move by the US was “shameful and irresponsible”.

Politics with Michelle Grattan: John Blaxland and Richard Holden talk about what Trump will mean for Australia

Source: The Conversation (Au and NZ) – By Michelle Grattan, Professorial Fellow, University of Canberra

As Australia gears up for the election, the incoming government’ Labor or Coalition, will face global challenges, geo-political and economic, especially with Donald Trump starting to impose tariffs on selected countries including China,

To discuss where Australia is placed to meet new circumstances we’re joined by two experts.

John Blaxland is Director of the ANU North America Liaison Office, based in Washington, and Professor of International Security and Intelligence Studies. Richard Holden is Professor of Economics at UNSW.

Blaxland outlines how Australia should continue to support the current international norms, and how changing norms could spell trouble,

The rules based international order is something that we are going to feel the absence of quite keenly. For small and middle powers like Australia the reliance on that order has obviated the need to spend up a lot on military capabilities and that’s going to shift.

We’ve seen the United States walking away from COP-related agreements but these arrangements still have global momentum and I would contend that Australia has an interest in continuing to support them as best as possible, particularly for the sake of our partners in the Pacific, but also just for our own sake.

On who could deal with Trump better, Blaxland doesn’t think it would make a lot of difference,

I don’t think the United States pays much attention to what happens internally in Australian politics and I think the Albanese government and Penny Wong and Richard Marles and others are wise to present as small a target as possible. The ALP is playing a difficult hand well in bilateral relations with the United States. Broadly it is still strongly in our interests to make that work as best we can.

There’s no question there’s a closer Liberal-Trump alignment, and that may make it easier. But the economic and security relations are key and here it’s important to remember that the United States has a trade surplus with Australia and so that means we’re not in his [Trump’s] crosshairs immediately for having the opposite, and America is the biggest foreign direct investor in Australia by a country mile.

Holden says of the economy internationally,

The global economy is well on the way to recovering from the post-pandemic inflation, the associated increases in most advanced economies and interest rates in most of those jurisdictions, are coming down. In some of those, New Zealand is an example there’s been a real hit to the economy. But it’s generally looking reasonably positive with the one big looming thing, which is what happens to international trade as a result of the Trump tariff threats that are now starting to be put into action.

But Holden is a bit more pessimistic about Australia’s economy,

Not to be too gloomy about things, I think the news is a little less good. So the Prime Minister I heard on your podcast recently and the Treasurer talking about their last two budgets, and while they’re right that there has been two small budget surpluses, that’s really off the back of just an extraordinary windfall in terms of tax revenue.

On debt,

If you look going forward, even so far government decisions have added $78 to $80 billion to that debt and the recent mid-year update, MYEFO reports the cumulative debt for the next four years will be over $140 billion of the increase.

I think there’s a sense that our fiscal house is really being put into really good shape and I don’t think that’s accurate.

Political donations data show who’s funding whom in Australia – but they are coming out far too late

Source: The Conversation (Au and NZ) – By Kate Griffiths, Deputy Program Director, Budgets and Government, Grattan Institute

As federal parliament reconvenes this week, the pre-election buzz is palpable. When will the election be called? Which policies are on the table? And who’s backing whom in this election campaign?

While the first two questions are yet to be answered, we ought to have a better sense of the third with the release of the annual political donations data.

There’s plenty to unpick in the new data but there’s one glaring problem: we are only just now learning about donations made in 2023–24. Australians are left in the dark about who is donating right now.

Here’s what happened in 2023–24

In 2023–24, Australia’s political parties collectively raised $166 million, with most of the money (85%) flowing to the major parties. In federal election years the totals can be more than double this, and donations at the past two federal elections have been heavily dominated by Clive Palmer giving to his own party (in 2019 and 2022).

The Coalition raised $74 million in 2023–24, with Labor not far behind on $68 million. The Greens were a distant third, with $17 million. Independents collectively declared just $2 million. In the lead-up to the last federal election, Labor raised $124 million, and the Coalition raised $115 million, so we would expect the major parties are raising much more right now.

The big donors

A few big donors dominate the $12 million in donations to political parties that are on the public record.

Billionaire Anthony Pratt donated $1 million to Labor (through Pratt Holdings), while the Coalition was supported by billionaires Harry Triguboff (through Meriton Property Services) and Gina Rinehart (Hancock Prospecting), to the tune of around half a million dollars each. Both Labor and the Coalition also received major donations from their investment arms (Labor Holdings and Cormack Foundation, respectively).

Other major donations included $575,000 to the Greens from Duncan Turpie, a longtime backer of the party; $474,000 from Climate 200 backing several independents (mainly Zoe Daniel and Monique Ryan); and $360,000 to the Greens from Lisa Barlow’s conservation trust.

The big donor missing here is Clive Palmer. The size of his donations – $117 million in 2022 and $84 million in 2019 – blow everyone else out of the water, but he tends only to donate in election years. We won’t know how much he’s spending on the current election campaign until February 2026.

What needs to change

Money matters because it helps spread political messages far and wide. But when political parties are highly dependent on a small number of powerful individuals, businesses, and unions, to fund their campaigns, this dependence creates enormous risks of private influence over decision-making in the public interest.

That’s why Australians need to know – in real time – who’s funding election campaigns.

Under the current rules, it takes at least seven months and sometimes up to 19 months for a large federal donation to be made public. Yet at state level, donations must be made public within a month during election campaigns, and within six months at other times.

Introducing quicker disclosure requirements at the federal level would mean Australians would know who’s donating while policy issues – and elections – are still “live”.

The donations disclosure threshold should also be lowered to give Australians better visibility of substantial donors. In 2023–24, declared donations made up only 7% of political parties’ total income. There are other sources of income on the public record (including public funding), but about 45% of party income remains hidden because the disclosure threshold is so high.

There is no exact science to choosing a threshold, but the current level of $16,900 is well above the amount an ordinary Australian could afford to contribute to a political cause.

This high threshold is made much worse by the fact that political parties are not required to aggregate multiple donations from the same donor. That means, for example, one donor could make many donations of $15,000, but because each is below the threshold, the party doesn’t need to declare them. The donor is expected to declare themselves to the Australian Electoral Commission, but this is almost impossible to police.

The federal government has a bill before the Senate that would reduce the donations disclosure threshold to $1,000, and make release of donations data more timely. These changes would substantially improve transparency around money in politics. But the bill also includes more complex reforms that may stall the progress of these transparency measures.

Better and more timely information on political donations is urgently needed as a public check on the influence of money in politics.

Let’s hope this is the last election Australians are left in the dark on who funds our political parties.

Can you get sunburnt or UV skin damage through car or home windows?

Source: The Conversation (Au and NZ) – By Theresa Larkin, Associate Professor of Medical Sciences, University of Wollongong

Zac Harris/Unsplash

When you’re in a car, train or bus, do you choose a seat to avoid being in the sun or do you like the sunny side?

You can definitely feel the sun’s heat through a window. But can you get sunburn or skin damage when in your car or inside with the windows closed?

Let’s look at how much UV (ultraviolet) radiation passes through different types of glass, how tinting can help block UV, and whether we need sunscreen when driving or indoors.

What’s the difference between UVA and UVB?

Of the total UV radiation that reaches Earth, about 95% is UVA and 5% is UVB.

UVB only reaches the upper layers of our skin but is the major cause of sunburn, cataracts and skin cancer.

UVA penetrates deeper into our skin and causes cell damage that leads to skin cancer.

Glass blocks UVA and UVB radiation differently

All glass used in house, office and car windows completely blocks UVB from passing through.

But only laminated glass can completely block UVA. UVA can pass through other glass used in car, house and office windows and cause skin damage, increasing the risk of cancer.

Car windscreens block UVA, but the side and rear windows don’t

A car’s front windscreen lets in lots of sunshine and light. Luckily it blocks 98% of UVA radiation because it is made of two layers of laminated glass.

But the side and rear car windows are made of tempered glass, which doesn’t completely block UVA. A study of 29 cars found a range from 4% to almost 56% of UVA passed through the side and rear windows.

The UVA protection was not related to the car’s age or cost, but to the type of glass, its colour and whether it has been tinted or coated in a protective film. Grey or bronze coloured glass, and window tinting, all increase UVA protection. Window tinting blocks around 95% of UVA radiation.

In a separate study from Saudi Arabia, researchers fitted drivers with a wearable radiation monitor. They found drivers were exposed to UV index ratings up to 3.5. (In Australia, sun protection is generally recommended when the UV index is 3 or above – at this level it takes pale skin about 20 minutes to burn.)

So if you have your windows tinted, you should not have to wear sunscreen in the car. But without tinted windows, you can accumulate skin damage.

UV exposure while driving increases skin cancer risk

Many people spend a lot of time in the car – for work, commuting, holiday travel and general transport. Repeated UVA radiation exposure through car side windows might go unnoticed, but it can affect our skin.

Indeed, skin cancer is more common on the driver’s side of the body. A study in the United States (where drivers sit on the left side) found more skin cancers on the left than the right side for the face, scalp, arm and leg, including 20 times more for the arm.

Another US study found this effect was higher in men. For melanoma in situ, an early form of melanoma, 74% of these cancers were on the on the left versus 26% on the right.

Earlier Australian studies reported more skin damage and more skin cancer on the right side.

Cataracts and other eye damage are also more common on the driver’s side of the body.

What about UV exposure through home or office windows?

We see UV damage from sunlight through our home windows in faded materials, furniture or plastics.

Most glass used in residential windows lets a lot of UVA pass through, between 45 and 75%.

Residential windows can let varied amounts of UVA through.
Sherman Trotz/Pexels

Single-pane glass lets through the most UVA, while thicker, tinted or coated glass blocks more UVA.

The best options are laminated glass, or double-glazed, tinted windows that allow less than 1% of UVA through.

Skylights are made from laminated glass, which completely stops UVA from passing through.

Most office and commercial window glass has better UVA protection than residential windows, allowing less than 25% of UVA transmission. These windows are usually double-glazed and tinted, with reflective properties or UV-absorbent chemicals.

Some smart windows that reduce heat using chemical treatments to darken the glass can also block UVA.

So when should you wear sunscreen and sunglasses?

The biggest risk with skin damage while driving is having the windows down or your arm out the window in direct sun. Even untinted windows will reduce UVA exposure to some extent, so it’s better to have the car window up.

For home windows, window films or tint can increase UVA protection of single pane glass. UVA blocking by glass is similar to protection by sunscreen.

When you need to use sunscreen depends on your skin type, latitude and time of the year. In a car without tinted windows, you could burn after one hour in the middle of the day in summer, and two hours in the middle of a winter’s day.

But in the middle of the day next to a home window that allows more UVA to pass through, it could take only 30 minutes to burn in summer and one hour in winter.

When the UV index is above three, it is recommended you wear protective sunglasses while driving or next to a sunny window to avoid eye damage.

Poison baits were used on 1,400 feral cats, foxes and dingoes. We studied their fate to see what works

Source: The Conversation (Au and NZ) – By Pat Taggart, Adjunct Fellow in Ecology, University of Adelaide

Bee Stephens, CC BY

Poisoned baits are the main way land managers control foxes, feral cats and dingoes. Baiting is done to reduce livestock and economic losses, or pressure on endangered wildlife.

Millions of baits are laid annually. But we still don’t understand how effective baiting actually is. Current evidence paints a mixed picture. That’s a problem, because baiting can have unintended consequences, such as killing native animals we don’t want to target. Some research suggests baiting can actually increase attacks on livestock, or that poisoning dingoes can increase feral cat and fox numbers and worsen the damage to native wildlife.

We need better evidence on what baiting does and doesn’t do. Our new research draws on data from 34 previous studies assessing baiting effectiveness. In total, these largely Australian studies summarised the fate of more than 1,400 cats, foxes and dingoes. We used these data sets to conduct the most comprehensive analysis of baiting effectiveness to date.

Baiting is ubiquitous

Baits can be purchased commercially or produced in-house. In some states, land managers can bring meat baits to government authorities to have poison added free of charge. They are then distributed by vehicle along tracks and roads or dropped from aircraft across vast areas of Australia, New Zealand and islands worldwide.

Single baiting programs can sometimes cover areas larger than 9,000 square kilometres – a land area similar to Puerto Rico or Cyprus.

So how can we best undertake these baiting programs?

1. Baiting does work

Across the 34 studies, baiting cut predator survival in half (51.7%) – substantially higher than the death rate in unbaited areas (16%).

This finding was broadly consistent regardless of whether baits were placed along tracks and roads or scattered over broader areas.

In some cases, predator numbers can recover rapidly following baiting. Under favourable conditions, feral cat and fox populations can double in a year, while dingo populations can grow 50% annually. But, under average conditions, such high rates of population increase are likely uncommon.

Predators from outside the control area can rapidly repopulate areas after a baiting program. For example, multiple studies have found no change in fox numbers even when baiting was conducted at monthly intervals. Similar results have been found after intensive fox shooting.

But there are also examples where prolonged, broad-scale baiting has worked well. To protect the threatened yellow footed rock wallaby, researchers baited around wallaby populations in New South Wales and South Australia and largely eliminated foxes from large areas. Wallaby numbers then increased.

2. Feral cats take baits too

Feral cats are opportunistic ambush predators and hunt a wide range of prey. They’re visually driven and prefer fresh meat. For these reasons, it’s long been thought they are less likely to eat poisoned bait than foxes and dingoes.

Feral cats are silent, stealthy hunters who prefer to hunt rather than scavenge.

But our analysis doesn’t support this – feral cats appeared to be just as susceptible to baits as foxes and dingoes. That’s good news for wildlife.

Significant and ongoing work has been put into designing better baits for feral cats to increase consumption rates. The most widely known of these baits is Eradicat, a sausage-style bait.

While this bait is aimed at feral cats, our analysis didn’t provide strong evidence showing Eradicat actually killed more feral cats than other poison bait recipes. This suggests any bait is more effective than no bait when it comes to cat control.

Eradicat baits have to be sweated to bring out the oils and make them more appealing.

3. Blanket coverage works better

In land manager circles, there’s a long-running debate over how best to bait. Some advocate putting out more baits over the same area, while others suggest more frequent baiting is better.

So which is it? Our analysis shows more baits in an area is likely to equate to better control of predators, while distributing baits more frequently may not have the same effect.

Why is this? Like people, animals are individuals, with their own behavioural tendencies. Wary animals may never take baits. Some foxes are known to store baits to eat later, by which time the baits may be less toxic, sickening rather than killing the animal.

This is believed to lead to bait aversion, where foxes avoid baits in the future due to previous bad experiences – just as we might avoid foods which made us sick.

A single, more intensive application of bait is likely to work better because susceptible predators eat the bait and die, and there is limited opportunity for bait aversion to develop. In contrast, more frequent baiting in a short period of time are of limited benefit because animals learn to avoid them.

Dingoes have been routinely baited for decades.
Ian Mayo, CC BY

Fresh baits have long been believed to be eaten more readily than dry baits.

But our analysis shows this may not always be true. Overall, the type of bait had little impact on whether or not it led to reduced predator survival.

Optimising baiting

More efficient control of predators will mean fewer baits are needed to achieve the same result. That, in turn, means less risk of harming other native animals, as well as reducing how much work and money it costs to control feral cats, foxes and dingoes.

Our research shows baiting does indeed cut the number of predators prowling an area. But it also shows many factors we thought were important in making a baiting program effective may only have a limited effect.

The goal of poison baiting is to reduce the damage predators do to livestock and wildlife. Baiting is an important and effective tool in reducing predator pressure on threatened species. But its efficacy – and the risk other animals could take the bait – means we have a responsibility to continually optimise its use and ensure its application is targeted.

Supersonic jets are making a comeback – but despite the hype, don’t expect to book yet

Source: The Conversation (Au and NZ) – By Chris James, UQ Amplify Senior Lecturer, Centre for Hypersonics, School of Mechanical and Mining Engineering, The University of Queensland

Rendering of Boom Supersonic’s proposed Overture supersonic airliner. Boom Supersonic

Late last week, American company Boom Supersonic flew faster than the speed of sound with its XB-1 supersonic demonstrator aircraft. It’s now the first piloted non-military aircraft to break the sound barrier since the Concorde was retired from service in 2003.

It’s the first step in Boom’s ambitious goal to have supersonic airliners carry passengers by 2029.

But what exactly is supersonic travel? There are good reasons why it’s not more common, despite the hype.

What is supersonic flight?

The Mach number is defined as a plane’s speed divided by the speed that sound waves move through the air. To “break the sound barrier” means to fly faster than the speed of sound, with Mach numbers greater than 1.

The Mach number is an important ratio: as a plane flies, it disturbs the air in front of it. These disturbances move at the speed of sound. In supersonic flight these disturbances combine to form shock waves around the vehicle.

When people say you can see a fighter jet before you hear it, they’re referring to supersonic flight: fighter jets can travel at around Mach 2.

The sound from the fighter jet is trapped inside its shock wave; until the shock wave moves to your position on the ground, you won’t hear the plane.

The allure of supersonic travel

For efficiency reasons, most passenger jets cruise slightly slower than the speed of sound, at around Mach 0.8 (this is subsonic flight).

Boom plans to build an airliner called Overture that can fly at Mach 1.7. Flying supersonically can drastically decrease flight times. The company claims a trip from New York to Rome on Overture could take just four hours and 40 minutes, instead of eight hours.

Boom isn’t the only company working on this lofty goal. American firm Spike Aerospace is also developing a supersonic business jet, with the tagline “delivering the world in half the time”.

This is the value proposition of supersonic passenger travel.

In limited ways, it did already exist in the 20th century. However, due to timing, bad luck and the laws of physics, it didn’t continue.

Remember the Concorde?

Designs for supersonic airliners began in the mid-20th century, and by the 1970s we had supersonic passenger flight.

There was the little-known Russian Tupolev-144 and Concorde, a Franco-British supersonic airliner operated by British Airways and Air France from 1976 to 2003.

Concorde had a capacity of up to 128 passengers and cruised at Mach 2. It regularly travelled from London to New York in around three hours. The flights were expensive, mainly shuttling business people and the rich and famous.

Why supersonic passenger flight didn’t take off

Concorde was designed in the 1960s when it seemed like supersonic passenger transport was going to be the next big thing.

Instead, the Boeing 747 entered commercial service in 1970. Cheap, large and efficient airliners like it blew Concorde out of the water.

Designed to cruise efficiently at supersonic speeds, Concorde was extremely fuel inefficient when taking off and accelerating. Concorde’s expensive, “gas guzzling” nature was a complaint levelled against it for most of its lifetime.

A catastrophic 1973 Paris air show crash of the competing Russian airliner, Tupolev Tu-144, also shifted public perception on supersonic flight safety at a time when many airlines were considering whether or not to purchase Concordes.

Only 20 Concordes were manufactured out of the planned 100. It is still disputed today whether Concorde ever made money for the airlines who operated it.

Noise is a real problem for supersonic flight

Remember the fighter jets? When a plane travels supersonically, its shock waves propagate to the ground, causing loud disturbances called sonic booms. In extreme cases they can shatter windows and damage buildings.

In the early 1970s, sonic boom concerns led the United States government to ban supersonic passenger flight over land in the US. This hurt the Concorde’s potential market, hence its only two regular routes were trans-Atlantic flights principally over the water.

The Concorde was also a very loud plane at take off, since it needed a lot of thrust to leave the ground.

The future of supersonic travel

A future for supersonic travel relies on solving some or all of the issues Concorde faced.

NASA and Lockheed Martin’s Quesst project aims to show sonic boom can be dissipated to manageable levels. They plan to fly their X-59 supersonic aircraft over US cities and gauge responses from citizens.

Quesst aims to use the geometry of the X-59, with a long elongated nose, to dissipate sonic booms to a weak “thump”, hopefully allowing supersonic airliners to travel over land in the future.

Spike Aerospace’s Spike S-512 Diplomat concept also aims to be a “quiet” supersonic aircraft with a less disruptive sonic boom.

Can Boom surpass Concorde?

Boom Supersonic don’t plan to fly supersonically over land. Their plan is to fly over land at Mach 0.94, which they claim will allow 20% faster overland travel than standard passenger airliners, even subsonically.

They also claim the design of their engines will ensure Overture is no louder than modern subsonic airliners when it takes off.

In terms of gas guzzling, they plan to use up to 100% sustainable aviation fuel to reduce emissions and their carbon footprint.

Concorde was made of aluminium using design tools available in the 1960s. Modern design methods and modern aerospace materials such as titanium and carbon fibre should also allow Overture and similar craft to weigh much less than Concorde, improving efficiency.

While Boom are currently receiving a lot of interest, with orders from many airlines, Concorde did have similar commitment before it become available. Most of it didn’t eventuate.

Additionally, Concorde was the product of an analogue era when the idea of flying to London or New York for the day for an important business meeting seemed like a necessary thing. In a world of remote work and video meetings, is there still a need for a supersonic airliner in the 2020s?

For now, supersonic airliners like Overture are likely to remain in the realm of the rich and famous, like Concorde did. But with modern technological advances, it will be interesting to see whether supersonic passenger travel once again becomes reality – or even goes mainstream. Only time will tell.

With the Gaza ceasefire in the balance, all eyes are on Benjamin Netanyahu’s trip to Washington

Source: The Conversation (Au and NZ) – By Amin Saikal, Emeritus Professor of Middle Eastern and Central Asian Studies, Australian National University

The brittle Gaza ceasefire between Israel and Hamas continues against all odds, given the depth of distrust and animosity between the warring parties.

Since its enactment nearly three weeks ago, Hamas has released more than a dozen Israeli hostages captured on October 7 2023, in return for some 400 Palestinian prisoners from Israeli jails. Should the process move forward as relatively smoothly as it has so far, more hostages and prisoners are set to be freed during the remainder of the first stage of the truce.

This is cause for a degree of optimism. However, negotiating the length, terms and implementation of the second and third stages of the ceasefire will prove very rocky.

Israeli Prime Minister Benjamin Netanyahu, for instance, has already declared the ceasefire to be “temporary”.

During the second stage, all Israeli hostages (alive and dead) are supposed to be freed in exchange for hundreds of prisoners. Israel is also expected to withdraw all its forces from Gaza as a prelude to the reconstruction of the coastal enclave in the final stage of the ceasefire.

There are many issues that could derail the process, two of which are crucial:

  • Israel’s unrealised goal of wiping out Hamas and securing Gaza for itself

  • Hamas’ resolve to regain sovereign control over Gaza.

Another factor is the influence of the new US president, Donald Trump. While
Netanyahu has the full support of Trump, it remains unclear how much appetite the US leader has for more conflict in the Middle East.

A meeting between the two in Washington this week could be pivotal to the success of the next phase of the ceasefire – or the resumption of the Gaza war.

Hamas’ survival at odds with Israel’s war aims

Israel has certainly degraded Hamas over the past 15 months of its scorched-earth operations in Gaza, which it launched in response to Hamas’ attacks on October 7 2023. However, it has not eliminated the group.

The appearance of well-armed and well-composed Hamas fighters in the choreographed three rounds of hostage transfers in the areas that Israel has demolished testifies to the group’s survival.

It essentially signals the failure of Netanyahu and his extremist supporters to achieve their main goals of uprooting Hamas and securing the release of the hostages through military action.

Netanyahu’s acceptance of the ceasefire at this point clearly underlines the futility of the use of force as the only means to seek vengeance against Hamas. With the conflict in a stalemate for months, he could have embraced the ceasefire much earlier, thereby securing a quicker hostage release without more lives lost or more damage to Israel’s already-tarnished international reputation.

Hamas’ survival means it is still a dangerous force, former US Secretary of State Antony Blinken said in mid-January. He said the group has “recruited almost as many new militants as it has lost” in the war.

Reports also indicate Hamas has also maintained its control over Gaza’s administration and security forces, despite Israel’s efforts to destroy it.

If that is the case, Israeli citizens – who have been highly polarised between those wanting the return of the hostages via a ceasefire and those backing Netanyahu’s government to continue the war – have the right to seriously question the prime minister’s leadership.

The same applies to Israel’s outside supporters, especially the United States.

Yet, this may not happen. The war-makers may win over the peace aspirants. For Netanyahu and his backers, the job is not finished. Many observers believe the very survival of Hamas can only motivate them further to resume the war once all the hostages are freed.

What does Trump want?

The future of the ceasefire now seems to hinge on Netanyahu’s meeting with Trump in Washington. According to media reports, the Israeli leader is keen to see where Trump stands on the second phase of the deal before negotiations continue.

Trump recently doubled down on his suggestion to “clear out” Gaza’s 2.3 million citizens – though he has mentioned a figure of 1.5 million – by relocating them to Egypt and Jordan. Given the previous statements of the extremists in Netanyahu’s shaky coalition, nothing would please them more than a depopulated and annexed Gaza.

Cairo and Amman, as well as other Arab countries, have firmly rejected the idea. Hamas and the enfeebled Palestinian Authority in the West Bank have outrightly condemned it.

But Trump has insisted the Egyptian and Jordanian leaders would eventually come around because the US does a lot for them – referring presumably to their dependence on substantial annual American aid.

If this plan were to transpire, it would not only be a recipe for more bloodshed and instability in the Middle East, but also more betrayal of the Palestinian cause and the two-state solution by the international community.

While a ray of hope exists for the continuation of the ceasefire and the implementation of the ceasefire’s second stage, it is still very possible that Netanyahu will return to military action to destroy Hamas and annex part or all of Gaza along the lines of what Trump has suggested.

The Trump-Netanyahu bond is so strong that it could even enable the Israeli leader to declare sovereignty over the West Bank.

Given these uncertainties, the third stage of the ceasefire regarding the reconstruction of Gaza, which is estimated to be upwards of US$80 billion (A$1.3 trillion), is at this point nothing more than words on a piece of paper.

The AEC wants to stop AI and misinformation. But it’s up against a problem that is deep and dark

Source: The Conversation (Au and NZ) – By Susan Grantham, Lecturer in Communication, Griffith University

From the moment you open your social media feed, you’re stepping into a digital battleground where not all political messages are what they seem.

The upcoming federal election will see an influx of deepfakes, doctored images, and tailored narratives that blur the line between fact and fiction.

Last week, the Australian Electoral Commission (AEC) relaunched its Stop and Consider campaign. The campaign urges voters to pause and reflect, particularly regarding information about how to vote. But its message applies to all forms of misinformation.

AEC Commissioner Jeff Pope warns:

A federal election must be held in the next few months, so now is the perfect time to encourage all Australians to have a healthy degree of scepticism when it comes to what they see, hear or read.

The simple directives outlined in this campaign are designed to slow the spread of misleading information in a digital age where algorithms boost engagement at speed.

So how effective is it likely to be in helping voters sift the real from the fake? While the campaign benefits from the AEC’s credibility and its accessible message, it also faces significant hurdles.

Digital deception in action

In 2024, AI made a notable impact on international political campaigns.

In the US, the Federal Communications Commission fined a political consultant $6 million for orchestrating fake robocalls that featured an AI-generated deepfake of President Joe Biden’s voice.

During India’s 2024 election, Meta (which owns Facebook) approved AI-manipulated ads spreading disinformation and hate. This exacerbated divisive narratives and failing to regulate harmful content.

Meanwhile, the Australian Labor Party deployed an AI-generated video of opposition leader Peter Dutton as part of its online efforts.

Additionally, the Liberal Party has again engaged duo Topham Guerin, who are known for their use of AI and controversial political tactics.

Political leaders are increasingly turning to platforms like TikTok to attract votes. But one of the problems with TikTok for users is that it encourages endless scrolling and can cause users to miss subtle inaccuracies.

Adding to these concerns is a recent scam in which doctored images and fabricated celebrity headlines were circulated. It created the illusion of legitimacy and defrauded many Australians of their money.

These incidents are a stark reminder of how quickly digital manipulation can mislead, whether in commercial scams or political messaging.

But are we taking it seriously?

South Korea has taken a decisive stance against AI-generated deepfakes in political campaigns by banning them outright. Penalties include up to seven years in prison or fines of 50 million won (A$55,400). This measure forms part of a broader legal framework designed to enforce transparency, accountability, and ethical AI use.

In Australia, teal independents are calling for stricter truth in political advertising laws. The proposed laws aim to impose civil penalties for misleading political ads, including disinformation and hate speech.

However, combating misinformation created by anonymous or unknown parties, such as AI-generated deepfakes, remains a challenge that may require further regulatory measures and technological solutions.

All of this is unfolding at a time when the approach to fact-checking is itself in flux. In January, Meta made headlines by scrapping its third-party fact-checking program in the US. This was done in favour of a “community notes” system. The change was championed by CEO Mark Zuckerberg as a way to reduce censorship and protect free expression.

However, critics warn that without independent oversight, misinformation could spread more easily, potentially leading to a surge in hate speech and harmful rhetoric. These shifts in digital policy only add to the challenge of ensuring that voters receive reliable information.

So, will the AEC’s campaign have any effect?

Amid these challenges, the “Stop and Consider” campaign arrives at a critical moment. Yet despite scholars’ repeated calls to embed digital literacy in school curriculums and community programs, these recommendations often go unheard.

The campaign is a positive step, offering guidance in an era of rapid digital manipulation. The simple message – to pause and verify political content — can help foster a more discerning electorate.

However, given the volume of misinformation and sophisticated targeting techniques, the campaign alone is unlikely to be a silver bullet. Political campaigns are growing ever more sophisticated. With the introduction of anonymous deepfakes, voters, educators, regulators, and platforms must work together to ensure the truth isn’t lost in digital noise.

A robust foundation in digital literacy is vital. Not only for this campaign to work but to help society distinguish credible sources from deceptive content. We must empower future voters to navigate the complexities of our digital world and engage more fully in democracy.

Globally, diverse strategies provide valuable insights.

While Australia’s “Stop and Consider” campaign takes a reflective approach, Sweden’s “Bli inte lurad” initiative is refreshingly direct. It warns citizens: “Don’t be fooled.”

By delivering clear, actionable tips to spot scams and misleading content, the Swedish model leverages its strong tradition of public education and consumer protection.

This no-nonsense strategy reinforces digital literacy efforts. It also highlights that safeguarding the public from digital manipulation requires both proactive education and robust regulatory measures.

It may be time for Australian regulators to act decisively to protect the integrity of democracy.

Want your loved ones to inherit your super? Here’s why you can’t afford to skip this one step

Source: The Conversation (Au and NZ) – By Tobias Barkley, Lecturer, La Trobe University

Ground Picture/Shutterstock

What happens to our super when we die? Most Australians have superannuation accounts but about one in five of us die before we can retire and actually enjoy that money.

If we do die early our money is paid out as super “death benefits”. They can be substantial. Even people who die young can have $200,000–$300,000 of death benefits through super life insurance.

Death benefits have recently been in the news for all the wrong reasons. Last week the Treasurer Jim Chalmers expressed concern about delays paying out death benefits.

The Law Council is concerned people do not have enough control over how death benefits are distributed. Others are devastated about death benefits being paid to alleged violent partners.

How can you decide who gets your unspent super?

Our first thought might be writing it in our will. However, super is not covered by our will as it does not become part of our deceased estate.

Instead, death benefits are distributed by the trustee of your superannuation fund. Under the law, there are two main mechanisms controlling distribution: binding nominations and the trustee’s discretion.

Wills don’t cover super so it is important to lock in a beneficiary using a binding nomination.

Every super member has the option to create a binding nomination. It’s like a will for your super that the super trustee is obliged to follow. It also needs two witnesses to execute it. However, there are actually more ways for a binding nomination to fail than for a will to fail.

The law only allows you to nominate certain people: your “dependants” or your estate. If you nominate anyone else your entire nomination stops being binding. Plus, unlike wills, there is no way to fix execution errors. Also, many binding nominations expire after three years.

If you don’t have a binding nomination, then the trustee can choose who your death benefit goes to. There are two main mechanisms controlling how the trustee chooses who gets your death benefit.

First, legislation requires the trustee to give the death benefit to your dependants or deceased estate before anyone else. This means that your parents, for example, will only receive something if you have no children, partner or other dependants.

Second, decisions made by trustees can be disputed by complaining to the Australian Financial Complaints Authority (AFCA). The authority has a rigid approach to who should get death benefits and trustees usually follow this course of action.

Research I’ve done with Xia Li of La Trobe University reveals what AFCA does in practice.

Most crucially, people’s wishes expressed in non-binding nominations were essentially ignored. Our research found there was no statistically significant association between being nominated in a non-binding nomination and receiving any of the death benefit. This was true even for recent nominations.

Other factors the complaints authority ignores are family violence and financial need. In one case, five daughters provided evidence, including a police report, that their deceased mother was a victim of violence perpetrated by her new partner. In keeping with the Federal Court, AFCA gave the alleged perpetrator everything because he alone would have benefited from the deceased’s finances if she had lived.

In another case, the deceased’s adult son received nothing despite living with disability and “doing it tough”. He had refused financial help so was not financially dependent. AFCA gave everything to the partner.

AFCA ignores these factors because of one key issue. It places “great weight” on whether beneficiaries are financially dependent on the deceased.

This means when choosing between a financial dependent – such as a new partner who shares home expenses with the deceased, and non-financial dependants, such as most adult children – AFCA will almost always give everything to the spouse.

A new spouse will often receive their partner’s death benefits ahead of the deceased’s non-dependent children.
Ground Picture/Shutterstock

Relying on financial dependence can be arbitrary. Unlike in family law, a de facto partner does not need to be living with you for two years before becoming entitled. For example, in one case AFCA gave a partner of possibly only seven months (and 41 years younger than the deceased) everything and the deceased’s three children aged 27–33 nothing.

Also, AFCA treats any regular payment that supports daily living as financial dependence. For example, a son paying A$100 a week board to parents means both parents are financially dependent on the son. In another case, payments from the deceased to his brother of $5,000, $7,000 and $5,000 made over a year was not financial dependence because they were irregular.

The whole process is slow. The average time it takes to resolve a death benefit case that goes to AFCA is nearly three years and the longest case I’ve seen took over six.

The only thing that you can do that will make a difference is execute a binding nomination; non-binding nominations are worthless.

But take care to execute your binding nomination correctly (get legal advice) and leave reminders for yourself to review it every three years.

Dating apps could have negative effects on body image and mental health, our research shows

Source: The Conversation (Au and NZ) – By Zac Bowman, PhD Candidate, College of Education, Psychology & Social Work, Flinders University

Dikushin Dmitry/Shutterstock

Around 350 million people globally use dating apps, and they amass an estimated annual revenue of more than US$5 billion. In Australia, 49% of adults report using at least one online dating app or website, with a further 27% having done so in the past.

But while dating apps have helped many people find romantic partners, they’re not all good news.

In a recent review, my colleagues and I found using dating apps may be linked to poorer body image, mental health and wellbeing.

We collated the evidence

Our study was a systematic review, where we collated the results of 45 studies that looked at dating app use and how this was linked to body image, mental health or wellbeing.

Body image refers to the perceptions or feelings a person has towards their own appearance, often relating to body size, shape and attractiveness.

Most of the studies we included were published in 2020 onwards. The majority were carried out in Western countries (such as the United States, the United Kingdom and Australia). Just under half of studies included participants of all genders. Interestingly, 44% of studies observed men exclusively, while only 7% included just women.

Of the 45 studies, 29 looked at the impact of dating apps on mental health and wellbeing and 22 considered the impact on body image (some looked at both). Some studies examined differences between users and non-users of dating apps, while others looked at whether intensity of dating app use (how often they’re used, how many apps are used, and so on) makes a difference.

More than 85% of studies (19 of 22) looking at body image found significant negative relationships between dating app use and body image. Just under half of studies (14 of 29) observed negative relationships with mental health and wellbeing.

The studies noted links with problems including body dissatisfaction, disordered eating, depression, anxiety and low self-esteem.

Dating apps are becoming increasingly common. But could their use harm mental health?

It’s important to note our research has a few limitations. For example, almost all studies included in the review were cross-sectional – studies that analyse data at a particular point in time.

This means researchers were unable to discern whether dating apps actually cause body image, mental health and wellbeing concerns over time, or whether there is simply a correlation. They can’t rule out that in some cases the relationship may go the other way, meaning poor mental health or body image increases a person’s likelihood of using dating apps.

Also, the studies included in the review were mostly conducted in Western regions with predominantly white participants, limiting our ability to generalise the findings to all populations.

Why are dating apps linked to poor body image and mental health?

Despite these limitations, there are plausible reasons to expect there may be a link between dating apps and poorer body image, mental health and wellbeing.

Like a lot of social media, dating apps are overwhelmingly image-centric, meaning they have an emphasis on pictures or videos. Dating app users are initially exposed primarily to photos when browsing, with information such as interests or hobbies accessible only after manually clicking through to profiles.

Because of this, users often evaluate profiles based primarily on the photos attached. Even when a user does click through to another person’s profile, whether or not they “like” someone may still often be determined primarily on the basis of physical appearance.

This emphasis on visual content on dating apps can, in turn, cause users to view their appearance as more important than who they are as a person. This process is called self-objectification.

People who experience self-objectification are more likely to scrutinise their appearance, potentially leading to body dissatisfaction, body shame, or other issues pertaining to body image.

There could be several reasons why mental health and wellbeing may be impacted by dating apps, many of which may centre around rejection.

Rejection can come in many forms on dating apps. It can be implied, such as having a lack of matches, or it can be explicit, such as discrimination or abuse. Users who encounter rejection frequently on dating apps may be more likely to experience poorer self-esteem, depressive symptoms or anxiety.

And if rejection is perceived to be based on appearance, this could lead again to body image concerns.

What’s more, the convenience and game-like nature of dating apps may lead people who could benefit from taking a break to keep swiping.

What can app developers do? What can you do?

Developers of dating apps should be seeking ways to protect users against these possible harms. This could, for example, include reducing the prominence of photos on user profiles, and increasing the moderation of discrimination and abuse on their platforms.

The Australian government has developed a code of conduct – to be enforced from April 1 this year – to help moderate and reduce discrimination and abuse on online dating platforms. This is a positive step.

Despite the possible negatives, research has also found dating apps can help build confidence and help users meet new people.

If you use dating apps, my colleagues and I recommend choosing profile images you feel display your personality or interests, or photos with friends, rather than semi-clothed images and selfies. Engage in positive conversations with other users, and block and report anyone who is abusive or discriminatory.

It’s also sensible to take breaks from the apps, particularly if you’re feeling overwhelmed or dejected.

NZ’s gene technology reform carries benefits and risks – a truly independent regulator will be vital

Source: The Conversation (Au and NZ) – By Sylvia Nissen, Senior Lecturer in Environmental Policy, Lincoln University, New Zealand

Getty Images

Genetic modification is back on the political agenda in New Zealand. The issue may not be as hotly contentious as it once was, but big questions remain about the way forward.

Last year, the National-led coalition government signalled its intent to reform genetic modification laws to provide more “enabling” and “modern” regulation. The subsequent gene technology bill was introduced in December and is currently before select committee.

The bill comes on the back of growing calls for New Zealand’s regulatory frameworks to become less restrictive.

One of the arguments often made is that the current system, in place since the 1990s, is holding back gene technology research by restricting it largely to laboratory-based experiments. By this account, New Zealand is falling behind in knowledge and expertise, while missing out on the benefits of these technologies.

Those benefits are said to span a wide range of areas, including agriculture, health, conservation and climate change.

There are some applications of genetic modification that have potential long-term public benefit and few or no alternatives. These includes the control of invasive wasps or the production of insulin. But plenty of challenges remain for many emerging forms of gene technology, not least the technical complexities.

There are also difficult questions that must be asked. Who benefits and who carries the risks of harm? What might be other hard-to-anticipate implications, spanning health, social, cultural, ethical, environmental, economic and trade concerns?

In conservation, for instance, questions need to be asked about how interventions might spread or interact with ecosystems that are already under strain or beyond our shores.

Genetic modification is a controversial political topic for good reason. As with many other technologies, the devil is in the detail. We should not fall for overly simple narratives that it is all about benefits, with little to no risk. Context matters, as does robust and responsible governance.

A not-so-independent regulator

It is important to take a close look at how decisions about genetic modification might be made under the proposed bill.

The suggested model is loosely based on Australia’s approach of a single gene technology regulator, which has been in place for two decades and is widely considered to be successful.

But there are crucial – and troubling – differences between the Australian model and what is proposed for New Zealand.

In Australia, the regulator is fully independent. The law is clear: the regulator “is not subject to direction from anyone” in making decisions about genetic modification.

The regulator has a charter which frames decisions, an office and biosafety committees that support their work, and they report to parliament as a whole (not just the government of the day).

In contrast, the proposed New Zealand bill claims the regulator is independent, but also says they are “subject to general policy directions given by the minister”.

It is worth looking deeper into what this means. The bill’s coversheet explains:

Government needs a mechanism to intervene if the regulator acts contrary to its policy objectives.

These objectives would be provided through general policy directions and would “ensure the regulator acts consistently with reform objectives”, including by changing risk tolerance.

Although a minister cannot intervene in decisions about specific applications, they would have the ability to change the parameters of the regulator’s decisions, with no apparent requirements for wider consultation.

This is not true independence by any stretch of the imagination – and a long way from the Australian approach.

A note of caution

If a minister is able to change the parameters of a regulator’s decisions at will, it is important to consider what doors might be opened that we may wish, in retrospect, remained shut.

For example, the recently released first report of the Science System Advisory Group calls for “attracting multinational corporations to undertake research and development in New Zealand”. The report alludes to genetic modification research as a key area to expand.

Put this together with the decision-making model proposed under the bill. It is not a stretch to see how a regulator, who was subject to the general policy direction of a minister, could be provided with a scope that facilitated multinational genetic modification research in New Zealand.

There is ample reason to be cautious of opening New Zealand to this. Numerous international scholars have highlighted that genetic modification research is “firmly dominated” by elite US-based or European science teams.

It is also increasingly funded by private philanthropists, corporations and the military, who often implement their experiments in distant countries or islands with relatively minimal regulation.

This practice has been given a specific term: “ethics dumping”.

Science might progress, but local communities are left with the unpredictable and unintended consequences of these experiments, usually without meaningful prior consultation.

It is therefore important that any changes to New Zealand’s genetic modification regulation ensure truly independent decision-making. There can be benefits of these technologies, but a system that can be changed at short notice to suit the government of the day could set the scene for more harm than good.

The devil really is in the detail. To have responsible governance, a few changes in the new law will make a significant difference.

Australia spends $714 per person on roads every year – but just 90 cents goes to walking, wheeling and cycling

Source: The Conversation (Au and NZ) – By Matthew Mclaughlin, Adjunct Research Fellow, The University of Western Australia

What could you buy for 90 cents? Not much – perhaps a banana.

Unfortunately, that’s how much the Australian government has invested per person annually on walking, wheeling and cycling over the past 20 years.

How would Australians’ lives change if that figure rose?

What makes a city great for running and how can we promote ‘runnability’ in urban design?


The state of play here and overseas

From 2008-2028, the federal government spent $384 million on the following active transport investments:

All up, about $714 per person is spent annually on roads; 90 cents out of this $714 is just pocket change.

Even if you don’t want to walk, wheel or ride, you should care because less driving helps everyone, including other drivers, who benefit from reduced traffic.

As a result of this over-investment in car road-building, Australia has the smallest number of walking trips of 15 comparable countries across Western Europe and North America.

Cycling rates are equally dismal.

Globally, the United Nations recommends nations spend 20% of their transport budgets on walking and cycling infrastructure.

Countries like France, Scotland, the Netherlands, Denmark, Sweden and the largest cities in China invest between 10% and 20%.

These places were not always known for walking and cycling – it took sustained redirecting of investment from roads to walking and cycling.

Meanwhile, many Australians are dependent on cars because they have no other choice in terms of transport options.

Why spend more on walking and cycling?

Road use is inherently dangerous – in Australia last year, more than 1,300 people died on our roads, which is more than 25 people a week.

Owning a car can also be expensive, which is especially concerning for those struggling with the cost-of-living.

The typical Australian household spends 17% of its income on transport – with car ownership making up 92.5% of that figure, compared to 7.5% on public transport.

Many Australians feel forced to own a car to get around, so investing in paths and public transport provides people the freedom to get around how they choose.

Congestion is getting worse in most major cities and we can’t build our way out of it with more or wider roads.

About two-thirds of car journeys in our cities could be walked, wheeled or cycled in 15 minutes or less, but these short car trips clog up our roads with traffic.

A major source of all emissions in Australia are from driving.

If more people felt safe to walk, cycle or take public transport, it would reduce this major emissions source.

There is a strong rationale and economic argument, too. The NSW government has estimated every kilometre walked benefits the national economy by $6.30, while every kilometre cycled benefits the economy by $4.10.

This means that by simply walking 500 metres to the local shops and back, you’re saving the economy about $6, while riding five kilometres to work and back saves a whopping $41 for the economy.



But where could we get this funding from?

Redirecting funding from the current road budget makes the most sense, because getting more people walking, wheeling and cycling eases pressure on the transport system (think of school holiday traffic).

This is a popular proposition. One study found two-thirds of Australians supported the redirection of funding from roads to walking and cycling infrastructure. Another found many Australians support building more walking and cycling paths where they live.

This is not a partisan issue: all Australians in all communities would benefit, including drivers who would face less traffic and enjoy more parking availability.

Unfortunately, false solutions to our unwalkable and un-cycleable communities continue to derail our focus on fixing the root cause of our problems. For example, telling people to ride to work, while not providing them a safe place to do so, doesn’t make sense.

What could $15 per person get us?

Investing $15 per Australian per year would create a better built environment to walk, wheel or ride and deliver significant economic, social and environmental benefits.

If this was matched with 50:50 funding from state and territory governments (which often happens with transport projects) over a ten-year period, this investment would deliver the four national projects already shortlisted on Infrastructure Australia’s infrastructure priority list for our largest capital cities: Sydney, Melbourne, Perth, Brisbane.

It could also fund up to 15 regional cities to build comprehensive networks. Wagga Wagga for example, is about to finish building a 56 kilometre network of walking and cycling paths. As a result, those using the network are 3.7 times more likely to meet physical activity guidelines than those who don’t.

Such an investment could also fund supporting initiatives, such as electric bike subsidies which have proven extremely popular in both Queensland and Tasmania.

What could $10 or $5 per person get us?

The Australian government could invest less than $15 per person – at $5 or $10 per year, the key projects outlined in Infrastructure Australia’s infrastructure priority list could still be targeted, but those would just take proportionally longer because there is less money.

Or, instead of investing in the four capital cities on the infrastructure priority list, it could invest in two.

A different approach could be to spend $5 or $10 to fund infrastructure for regional towns, but this wouldn’t help the problems in our capital cities.

When it comes to transport, the saying goes “we get what we build” – so if we build more roads, we get more people driving. If we build paths, we get more people walking and cycling short journeys and our roads are less congested.

We need bold solutions, and $15 should be seen not as an extravagance.

How psychologists kick-started AI by studying the human mind

Many people think of psychology as being primarily about mental health, but its story goes far beyond that.

As the science of the mind, psychology has played a pivotal role in shaping artificial intelligence, offering insights into human cognition, learning and behaviour that have profoundly influenced AI’s development.

These contributions not only laid the foundations for AI but also continue to guide its future development. The study of psychology has shaped our understanding of what constitutes intelligence in machines, and how we can address the complex challenges and benefits associated with this technology.

Machines mimicking nature

The origins of modern AI can be traced back to psychology in the mid-20th century. In 1949, psychologist Donald Hebb proposed a model for how the brain learns: connections between brain cells grow stronger when they are active at the same time.

This idea gave a hint of how machines might learn by mimicking nature’s approach.

In the 1950s, psychologist Frank Rosenblatt built on Hebb’s theory to develop a system called the perceptron.

The perceptron was the first artificial neural network ever made. It ran on the same principle as modern AI systems, in which computers learn by adjusting connections within a network based on data rather than relying on programmed instructions.

A scientific understanding of intelligence

In the 1980s, psychologist David Rumelhart improved on Rosenblatt’s perceptron. He applied a method called backpropagation, which uses principles of calculus to help neural networks improve through feedback.

Backpropagation was originally developed by Paul Werbos, who said the technique “opens up the possibility of a scientific understanding of intelligence, as important to psychology and neurophysiology as Newton’s concepts were to physics”.

Rumelhart’s 1986 paper, coauthored with Ronald Williams and Geoffrey Hinton, is often credited with sparking the modern era of artificial neural networks. This work laid the foundation for deep learning innovations such as large language models.

In 2024, the Nobel Prize for Physics was awarded to Hinton and John Hopfield for work on artificial neural networks. Notably, the Nobel committee, in its scientific report, highlighted the crucial role psychologists played in the development of artificial neural networks.

Hinton, who holds a degree in psychology, acknowledged standing on the shoulders of giants such as Rumelhart when receiving his prize.

Self-reflection and understanding

Psychology continues to play an important role in shaping the future of AI. It offers theoretical insights to address some of the field’s biggest challenges, including reflective reasoning, intelligence and decision-making.

Microsoft founder Bill Gates recently pointed out a key limitation of today’s AI systems. They can’t engage in reflective reasoning, or what psychologists call metacognition.

In the 1970s, developmental psychologist John Flavell introduced the idea of metacognition. He used it to explain how children master complex skills by reflecting on and understanding their own thinking.

Decades later, this psychological framework is gaining attention as a potential pathway to advancing AI.

Fluid intelligence

Psychological theory is increasingly being applied to improve AI systems, particularly by enhancing their capacity for solving novel problems.

For instance, computer scientist François Chollet highlights the importance of fluid intelligence, which psychologists define as the ability to solve new problems without prior experience or training.

ARC Prize

In a 2019 paper, Chollet introduced a test inspired by principles from cognitive psychology to measure how well AI systems can handle new problems. The test – known as the Abstract and Reasoning Corpus for Artificial General Intelligence (ARC-AGI) – provided a kind of guide for making AI systems think and reason in more human-like ways.

In late 2024, OpenAI’s o3 model demonstrated notable success on Chollet’s test, showing progress in creating AI systems that can adapt and solve a wider range of problems.

The risk of explanations

Another goal of current research is to make AI systems more able to explain their output. Here, too, psychology offers valuable insights.

Computer scientist Edward Lee has drawn on the work of psychologist Daniel Kahneman to highlight why requiring AI systems to explain themselves might be risky.

Kahneman showed how humans often justify their decisions with explanations created after the fact, which don’t reflect their true reasoning. For example, studies have found that judges’ rulings fluctuate depending on when they last ate — despite their firm belief in their own impartiality.

Lee cautions that AI systems could produce similarly misleading explanations. Because rationalisations can be deceptive, Lee argues AI research should focus on reliable outcomes instead.

Technology shaping our minds

The science of psychology remains widely misunderstood. In 2020, for example, the Australian government proposed reclassifying it as part of the humanities in universities.

As people increasingly interact with machines, AI, psychology and neuroscience may hold key insights into our future.

Our brains are extremely adaptable, and technology shapes how we think and learn. Research by psychologist and neuroscientist Eleanor Maguire, for example, revealed that the brains of London taxi drivers are physically altered by using a car to navigate a complex city.

As AI advances, future psychological research may reveal how AI systems enhance our abilities and unlock new ways of thinking.

By recognising psychology’s role in AI, we can foster a future in which people and technology work together for a better world.

Podcasts have helped sway many young American men to the right. The same may well happen in Australia

Source: The Conversation (Au and NZ) – By Raffaele F Ciriello, Senior Lecturer in Business Information Systems, University of Sydney

The 2024 US presidential election saw a historic shift to the right, driven by the largest swing of young male voters in two decades. Analysts attribute this partly to podcasters like Joe Rogan, whose unfiltered, conversational content bypassed traditional media to mobilise this demographic.

Our own research shows that Donald Trump’s podcast strategy during the election campaign boosted his support by 1% to 2.6%, with more than half of this linked to Rogan’s platform. In contrast, Kamala Harris’s reliance on traditional, curated media lacked the authenticity that resonated with Trump’s base.

This trend has clear parallels in Australia, where media strategy has long mirrored the US. In 1949, Robert Menzies used radio to reassure the public, much like Franklin D. Roosevelt’s “fireside chats”. In the 1980s, television brought Bob Hawke into voters’ homes, showcasing charisma akin that of John F. Kennedy in his earlier televised debates. Kevin Rudd’s 2007 “Kevin 07” campaign effectively mirrored Barack Obama’s use of social media to engage younger voters. Similarly, Scott Morrison’s 2019 campaign emulated Trump-style microtargeting on Facebook to connect with specific demographics.

Today, podcasts have become the latest battleground for political influence. Their conversational, long-form format enables politicians to address complex issues in a direct, personal manner. This medium resonates particularly with younger voters, who are increasingly turning away from traditional media.

The 2025 federal election will likely see a turning point in the influence of podcasts on election campaigns, and even the outcome.

The Australian podcasting landscape

Podcast consumption in Australia continues to rise, with listenership increasing by 8.7% in early 2024. This comes after reaching a record 43% in 2023, up from 17% in 2017.

Dubbed “the world’s most avid podcast listeners”, Australian men aged 18–34 dominate the audience, drawn to popular news and politics podcasts such as ABC News Top Stories and The Party Room, as well as global hits like The Joe Rogan Experience.

Podcasts appeal through their intimacy and authenticity, fostering a “close-knit friend group” atmosphere. Younger voters increasingly use podcasts to explore issues such as housing affordability and climate change.

Rogan’s podcast exemplifies this appeal, particularly among young Australian men. With 80% of his audience male, and half aged 18–34, Rogan’s unapologetic masculinity and focus on topics such as combat sports, hunting and societal controversies position him as a counterbalance to identity politics. His “living room” style, seen during Trump’s three-hour appearance, makes polarising or extremist ideas more palatable. This reflects a broader cultural shift among young men toward what they see as “traditional values”.

While podcasts often feature diverse viewpoints, their unregulated nature can expose listeners to harmful ideologies, fostering echo chambers or radicalisation. Misinformation spreads more easily in these spaces, as evidenced by the US, where fragmented media contributed to the rise of Trumpism. Although Australia’s stricter campaign finance laws and media regulations reduce such risks, they cannot eliminate them entirely.

As the 2025 election nears, understanding how podcasts shape voter behaviour is critical for balanced political discourse and social cohesion.

Australia’s political landscape

Recent polls show the Liberal-National Coalition leading Labor 53.1% to 46.9% in two-party preferred voting, with 39% of voters preferring Peter Dutton as prime minister compared with Anthony Albanese’s 34%. While the Coalition uses Trump-style strategies, Albanese appears to have a problem with male voters.

Dutton emulates Trump in using podcasts to connect directly with young male voters and amplify culture war themes, anti-woke sentiment, and populist rhetoric.

His Elon Musk-inspired push for a “government efficiency” department mirrors Trump’s populist promises of cutting “wasteful spending”.

The Coalition has tapped into a broader cultural shift among young men. Many of these men have gravitated toward influencers like Andrew Tate – alleged rapist and human trafficker with ambitions to become UK prime minister – whose divisive rhetoric reinforces regressive ideals.

Surveys reveal 28% of Australian teenage boys admire Tate, while 36% find him relatable. Moreover, half of surveyed schools link his influence to negative behavioural changes.

These strategies seem to work, with polls showing increased male voter support for the Coalition (52.7% to Labor’s 47.3%).

Australia’s compulsory voting and multi-party preferential system encourage broad-based appeals. But they also risk amplifying polarisation.

Australia’s concentrated media ownership, dominated by Rupert Murdoch’s News Corp, further shapes public discourse by amplifying conservative perspectives.

Although younger Australians – especially women – remain a strong progressive base for Labor, the rise of right-wing podcasts and their impact on young male voters poses a significant challenge. The Coalition’s ability to connect with this demographic via podcasts, leveraging dissatisfaction and cultural shifts, could shape the election’s outcome.

Opportunity and risk

Podcasts present both opportunities and risks for Australian politics. They offer a powerful platform for politicians to engage younger voters on crucial issues, fostering deeper connections. However, their unregulated nature enables the spread of misinformation and the normalisation of polarising ideas.

To address this, voters should critically evaluate podcast content, fact-check claims using resources such as RMIT ABC Fact Check and AAP FactCheck, and seek diverse perspectives. Politicians, meanwhile, must use podcasts strategically, balancing authenticity with accountability.

Progressive ideas could better resonate with young male audiences by reframing topics such as climate action, housing affordability and workplace equity as opportunities for leadership, empowerment and responsibility. Partnering with relatable influencers and using accessible, conversational podcast formats can help progressives connect with this demographic.

Pregnant women can now get a free RSV shot. What other vaccines do you need when you’re expecting?

Source: The Conversation (Au and NZ) – By Archana Koirala, Paediatrician and Infectious Diseases Specialist, University of Sydney

From today, February 3, pregnant women in Australia will be eligible for a free RSV vaccine under the National Immunisation Program.

This vaccine is designed to protect young infants from severe RSV (respiratory syncytial virus). It does so by generating the production of antibodies against RSV in the mother, which then travel across the placenta to the baby.

While the RSV vaccine is a new addition to the National Immunisation Program, it’s one of three vaccines provided free for pregnant women under the program, alongside ones for influenza and whooping cough. Each offers important protection for newborn babies.

The RSV vaccine

RSV is the most common cause of lower respiratory infections (bronchiolitis and pneumonia) in infants. It’s estimated that of every 100 infants born in Australia each year, at least two will be hospitalised with RSV by six months of age.

RSV infection is most common roughly between March and August in the southern hemisphere, but infection can occur year-round, especially in tropical areas.

The vaccine works by conferring passive immunity (from the mother) as opposed to active immunity (the baby’s own immune response). By the time the baby is born, their antibodies are sufficient to protect them during the first months of life when they are most vulnerable to severe RSV disease.

The RSV vaccine registered for use in pregnant women in Australia, Abrysvo, has been used since 2023 in the Americas and Europe. Real-world experience there shows it’s working well.

For example, over the 2024 RSV season in Argentina, it was found to prevent 72.7% of lower respiratory tract infections caused by RSV and requiring hospitalisation in infants aged 0–3 months, and 68% among those aged 0–6 months. This research noted three deaths from RSV, all in infants whose mothers did not receive the RSV vaccine during pregnancy.

This was similar to protection seen in a large multinational clinical trial that compared babies born to mothers who received this RSV vaccine with babies born to mothers who received a placebo. This study found the vaccine prevented 82.4% of severe cases of RSV in infants aged under three months, and 70% under six months, and that the vaccine was safe.

In addition to the maternal vaccine, nirsevimab, a long-acting monoclonal antibody, provides effective protection against severe RSV disease. It’s delivered to the baby by an intramuscular injection, usually in the thigh.

Nirsevimab is recommended for babies born to women who did not receive an RSV vaccine during pregnancy, or who are born within two weeks of their mother having received the shot (most likely if they’re born prematurely). It may also be recommended for babies who are at higher risk of RSV due to a medical condition, even if their mother was vaccinated.

Nirsevimab is not funded under the National Immunisation Program, but is covered under various state and territory-based programs for infants of mothers who fall into the above categories.

But now we have a safe and effective RSV vaccine for pregnancy, all pregnant women should be encouraged to receive it as the first line of prevention. This will maximise the number of babies protected during their first months of life.

Flu and whooping cough

It’s also important pregnant women continue to receive flu and whooping cough vaccines in 2025. Like the RSV vaccine, these protect infants by passing antibodies from mother to baby.

There has been a large whooping cough outbreak in Australia in recent months, including a death of a two-month-old infant in Queensland in November 2024.

The whooping cough vaccine, given in combination with diphtheria and tetanus, prevents more than 90% of whooping cough cases in babies too young to receive their first whooping cough vaccine dose.

Similarly, influenza can be deadly in young babies, and maternal flu vaccination substantially reduces hospital visits associated with influenza for babies under six months. Flu can also be serious for pregnant women, so the vaccine offers important protection for the mother as well.

COVID vaccines are safe in pregnancy, but unless a woman is otherwise eligible, they’re not routinely recommended. You can discuss this with your health-care provider.

When and where can you get vaccinated?

Pregnant women can receive these vaccines during antenatal visits through their GP or in a specialised antenatal clinic.

The flu vaccine is recommended at any time during pregnancy, the whooping cough vaccine from 20 weeks (ideally before 32 weeks), and the RSV vaccine from 28 weeks (before 36 weeks).

It’s safe to receive multiple vaccinations at the same clinic visit.

We know vaccination rates have declined in a variety of groups since the pandemic, and there’s evidence emerging that suggests this trend has occurred in pregnant women too.

A recent preprint (a study yet to be peer-reviewed) found a decrease of nearly ten percentage points in flu vaccine coverage among pregnant women in New South Wales, from 58.8% in 2020 to 49.1% in 2022. The research showed a smaller drop of 1.4 percentage points for whooping cough, from 79% in 2020 to 77.6% in 2022.

It’s important to work to improve vaccination rates during pregnancy to give babies the best protection in their first months of life.

We know pregnant women would like to receive information about new and routine maternal vaccines early in pregnancy. In particular, many pregnant women want to understand how vaccines are tested for safety, and their effectiveness, which was evident during COVID.

GPs and midwives are trusted sources of information on vaccines in pregnancy. There’s also information available online on Sharing Knowledge About Immunisation, a collaboration led by the National Centre for Immunisation Research and Surveillance.

Demolition should be the last resort for Melbourne’s 44 public housing towers – retrofit and upgrade instead

Source: The Conversation (Au and NZ) – By Nigel Bertram, Practice Professor of Architecture, Monash University

Investment in public housing is long overdue. But the current proposal to demolish all 44 of Melbourne’s social housing towers, relocate more than 10,000 residents and redevelop the sites is deeply flawed.

This blanket approach risks repeating the traumatic dislocation of vulnerable communities that happened when the towers were built more than 50 years ago. It also involves wasting money, energy and construction materials.

The state government says the old high-rises are being redeveloped to meet modern standards and house more people. But the decision to demolish and rebuild, rather than upgrade, has been challenged repeatedly.

I coauthored one of the most recent reports from concerned independent architects, urban designers and researchers. Together we argue retrofitting and upgrading existing housing stock, when combined with strategic new building, is technically feasible, cheaper and better for people and the planet.

At the same time, a class action lawsuit is awaiting a legal ruling on whether the government should be forced to release documents justifying demolition over retrofitting.

We know retaining and reusing existing structures saves energy and other resources, ultimately reducing greenhouse gas emissions. Across 44 buildings, this could also save around A$1.5 billion in construction costs.

Playing the numbers game

The federal government has set a national target to build 1.2 million homes by 2029. Victoria has a “bold” target to build 800,000 new homes over the next ten years. But how they go about meeting these targets matters too.

Melbourne’s housing commission towers are home to established communities, where connections between people have developed over a long period. This has immense social value.

The 44 towers also represent substantial embodied carbon. This is the carbon dioxide (CO₂) already emitted in extracting, manufacturing, transporting, installing and eventually disposing of existing concrete, bricks and other reusable materials.

Our analysis of one tower at Atherton Gardens estate revealed a potential saving of 16,000 tonnes of CO₂ through retrofitting. Multiplying this by 44 adds up to more than 700,000 tonnes – roughly equivalent to taking 150,000 cars off the road.

Taking tips from overseas

Overseas, similar postwar housing precincts have been updated and redeveloped in a more careful, considered way. Residents have even been able to stay in place while improvements are made. Such approaches incorporate a mix of renovation and retrofitting of existing buildings, combined with new infill and upgrades to public open spaces.

This approach integrates the precincts into the surrounding city and upgrades facilities to contemporary standards – without wholesale disruption and dislocation of the residents and their established communities.

It’s hard to know whether this work was considered during the decision-making process. The Victorian government and its housing agency Homes Victoria have so far refused to release the relevant reports or documents explaining their reasoning.

Such lack of transparency and consultation led to the launch of the class action. Residents at the Flemington and North Melbourne Estates have come together to argue their human rights were not considered when the decision to demolish their homes was made.

Two reports provide independent analysis

Filling the void, professional groups have undertaken two separate independent studies on a pro-bono basis. These reports analyse the different options based on the available information.

I helped compare three scenarios for a 20-storey tower at Atherton Gardens, Fitzroy. The research analysed two retrofit scenarios for the tower and compared these with a hypothetical equivalent new building.

We established the scope of building works required for each scenario. The team then measured capital cost, embodied carbon and carbon during operation for each case.



We found considerable savings can be made in capital costs (25–30%), embodied carbon (34–36%) and construction time (15–20%) through retrofitting, compared with constructing an equivalent new building.

When multiplied over 44 towers, these savings amount to about A$1.5 billion in raw construction value alone. This is without considering the additional costs of relocating existing residents, providing alternative accommodation during construction, or the social and health and wellbeing costs associated with long-term dislocation of communities.

A separate more detailed report on the Flemington Estate was released in October by charitable not-for-profit design and research practice OFFICE. Both reports independently arrived at very similar solutions for ways to address structural, fire and servicing upgrades.

Breaking down the barriers

Several reasons have been circulated as to why these high-rise towers are unsuitable for retrofitting. The two reports go through each in turn.

The towers are constructed from precast concrete slabs and internal walls are load-bearing. This makes refurbishment difficult, because the majority of walls cannot be moved. The buildings were also designed when the requirement to resist earthquakes was minimal.

A range of other technical hurdles, such as improving acoustic, thermal and fire separation and repairing degraded concrete, would also complicate upgrades. But none of these issues is insurmountable.

Both reports include strategies to address these issues, costed into the estimates. For example, the cost of strengthening to meet earthquake codes has been estimated as $1.73 million in Flemington and $3.85 million for Atherton Gardens. That’s around 3.7% of the total $105 million estimated construction cost for a single Atherton Gardens tower.

Exploring alternatives

The fact a building does not meet current regulatory standards is not in itself a reason for demolition. More than 80% of the city’s buildings would fail to meet these standards, including everything built in the 19th and 20th centuries. Our building codes recognise the value of existing structures and have provisions for renovation scenarios.

Retention and reuse of existing building fabric can achieve results surpassing current legislative standards while minimising waste, retaining the value of existing embodied carbon, and retaining the fabric, character and social memory of the city in the process.

Retrofitting can also avoid the mass displacement of existing residents, who would otherwise need to be accommodated during the construction phase. For instance, construction can allow refurbishment on a floor-by-floor basis, minimising relocation time for residents.

With the right design, skilled consultants, and genuine care for residents, it’s possible to overcome the barriers typically faced when reusing existing building stock.

I am grateful to Simon Robinson of OFFICE for his contributions to this article.

How we’re recovering priceless audio and lost languages from old decaying tapes

Source: The Conversation (Au and NZ) – By Nick Thieberger, Associate Professor in Linguistics and a Chief Investigator in the Centre of Excellence for the Dynamics of Language, The University of Melbourne

Nick Thieberger

Remember cassettes? If you’re old enough, you might remember dropping one into a player, only to have it screech at you when you pressed “play”. We’ve fixed that problem. But why would we bother?

Before the iPod came along, people recorded their favourite tunes straight from the radio. Some of us made home recordings with our sibling and grandparents – precious childhood snippets.

And a few of us even have recordings from that time we travelled to a village in Vanuatu, some 40 years ago, and heard the locals performing in a language that no longer exists.

In the field of linguistics, such recordings are beyond priceless – yet often out of reach, due to the degradation of old cassettes over time. With a new tool, we are able to repair those tapes, and in doing so can recover the stories, songs and memories they hold.

A digital humanities telescope

Our digital archive, PARADISEC (Pacific and Regional Archive for Digital Sources in Endangered Cultures) contains thousands of hours of audio – mainly from musicological or linguistic fieldwork. This audio represents some 1,360 languages, with a major focus on languages of the Pacific and Papua New Guinea.

The PARADISEC research project was started in 2003 as a collaboration between the universities of Melbourne and Sydney, and the Australian National University.

Like a humanities telescope, PARADISEC allows us to learn more about the language diversity around us, as we explained in a 2016 Conversation article.

Lubing the screech

While many of the tapes we get are in good condition and can be readily played and digitised, others need special care, and the removal of mould and dirt.

We work with colleagues at agencies such as the Solomon Islands National Museum, for whom we recently repaired a set of cassettes that were previously unplayable and just screeched. We’ll be taking those cassettes, now repaired and digitised, back to Honiara in February and expect to pick up more for further treatment.

Screeching happens when a tape is dried out and can’t move through the mechanism easily. The screeching covers the audio signal we want to capture.

In 2019, my colleague Sam King built (with the help of his colleague Doug Smith) a cassette-lubricating machine while working at the Australian Institute of Aboriginal and Torres Strait Islander Studies. This machine – likely the first of its kind in Australia – allowed us to play many previously unplayable tapes.

Last year, Sam built two versions of an updated machine called the LM-3032 Tape Restorator for PARADISEC, improving on the previous model. Between hand building some parts, 3D printing others and writing code for the controllers, it took him more than a year.

The 2024 LM-3032 Tape Restorator is an improved version of a model built in 2019.

Preserving culture and heritage

The LM-3032 Tape Restorator works by applying cyclomethicone (a silicone-based solvent used in cosmetics) to the length of a tape. This leaves behind an extremely thin film of lubrication that allows smoother playback, making digitisation possible. See more details here.

Tests have shown this process has no negative long-term effects on the tape. In fact, tapes treated with this method five years ago still play without issues.

This technological wizardry allows us to salvage precious analogue recordings before it’s too late. For many languages, these may be the only known recordings – stored on a single cassette, in a single location, and virtually inaccessible. Some of the primary research records digitised by PARADISEC have survived long periods of neglect in offices, garages and attics.

The audio below is from a tape that was kept at Fitzroy Crossing in the Kimberley for 40 years. It features beautiful singing in the local Walmajarri language, with guitar accompaniment. The first seven seconds are from the untreated tape, while the rest is from the treated version.

Our experience has shown community members truly value finding records in their own languages, and we’re committed to making this process easier for them.

Here’s one testimonial from E’ava Geita, Papua New Guinea’s current acting Solicitor General. In 2015, Geita was overjoyed to hear digitised records capturing PNG’s Koita language:

If only you witnessed and captured the reaction in me going through the recordings at home! It is quite an amazing experience! From feeling of awe to emotion to deep excitement! The feeling of knowing that your language has been documented or recorded in a structured way, kept safely somewhere in the world, hearing it spoken 50–60 years ago and by some people you haven’t seen but whose names you only hear in history is quite incredible. It is most heartwarming to know that it is possible to sustain the life of my language. Thank you once again for the opportunity to listen to the records.

KiwiSaver shakeup: private asset investment has risks that could outweigh the rewards

Source: The Conversation (Au and NZ) – By Aaron Gilbert, Professor of Finance, Auckland University of Technology

New Zealand’s superannuation is no longer enough to live on for the country’s retirees. Research has found people need hundreds of thousands in savings to live a comfortable life after work.

But the KiwiSaver scheme, introduced in 2007 to encourage New Zealanders to build their retirement savings, continues to be a political football. Since its creation, there have been multiple tweaks to the scheme, threatening to undermine its core purpose: supporting New Zealanders in their retirement.

In late 2024, the government proposed changes that would make it easier for KiwiSaver managers to invest in private assets.

The government says these changes could unlock billions to fund essential infrastructure or to provide capital for businesses, outcomes that could benefit the country as a whole.

But the changes required to enable investing in private assets – such as reduced transparency around fees – are concerning and may not be worth the limited benefits it would bring to KiwiSaver members.

Expanding KiwiSaver

At the moment KiwiSaver managers predominantly invest in publicly traded assets, specifically stocks and bonds.

The changes would open up KiwiSaver investors to a wide range of opportunities such as infrastructure projects (for example, toll roads), unlisted companies (KiwiBank has already been suggested by one provider) and property investments, among others.

Increasing private asset exposure from the current 2-3% of funds under management to a level similar to Australian super funds (15%+) could unlock significant investment for infrastructure or business capital.

But while there is definite appeal in using more KiwiSaver money to build roads and other essential infrastructure, the benefits to investors may be more modest.

The Ministry of Business, Innovation and Employment argues private assets may increase fund returns and should reduce risk for investors by reducing fund exposure to stock and bond markets.

But to achieve these possible outcomes KiwiSaver members risk being locked into a fund provider or having their funds split across providers when they opt to move. There is also the concern that transparency around the fees being charged by managers could worsen.

Gumming up the works

The advantage of the current system of investing in publicly traded assets is that they are relatively cheap to trade, can be bought or sold quickly and their market value is constantly known.

Private assets are none of these things.

Fund managers are currently required to release your funds within ten days when you opt to switch manager. Large investments in private assets that can not be sold quickly, or even worse, may be distressed (where the value is currently significantly below what it was bought for), could create a liquidity issue for a fund if a lot of investors decide to switch.

To encourage managers to invest in private assets the proposed changes would allow your existing fund manager to hold onto a portion of your investment until private assets could be liquidated if they deemed it in your best interest.

Essentially, you may have to stay with a fund manager for an indeterminate period even if you want to change, presumably while still paying them fees on the funds they are looking after.

Hiding fees

The government’s changes also suggest allowing managers to change the way the fees they report is calculated.

To encourage managers to invest in private assets, the government has proposed allowing them to exclude the costs associated with private assets from their reported fees. Why? Because private asset investing is significantly more expensive.

Managers may need to build specialised teams to evaluate private asset investments. There are substantial costs (consultants, lawyers, experts etc) incurred when evaluating these investments in the same way that a home buyer faces costs such as builder and valuer reports.

Additionally, managers will need to hire valuers periodically to reevaluate the value of the assets, resulting in more costs.

Removing private asset costs from disclosures will make it harder for New Zealanders to compare the fees on different funds.

Multiple other problems

Several other problems also exist with the plan.

The KiwiSaver market is relatively fragmented with 21 providers, nearly half of which manage less than NZ$1 billion in assets. Many private asset investments would require tens of millions, which means funds run the risk of becoming heavily exposed to just a few large investments. Only a handful of funds currently have the size to effectively use private assets to reduce investor risk.

There is also the difficulty in valuing private assets. Valuers can provide a best guess, but it will depend largely on what the market is willing to pay at the time you come to sell.

What is also unclear is how the value of private assets will be reflected in the unit prices that impact the price at which you buy into or sell out of fund. This introduces yet more opacity to a system that is currently transparent.

KiwiSaver will increasingly become a critical aspect of New Zealanders’ retirement. Changes to it need to be carefully considered and evaluated to avoid undermining confidence in KiwiSaver and to ensure that they support the primary goal, ensuring financial security in retirement. It is not clear that this change meets that threshold.

Palestine prisoners’ release ‘symbolic win’ showing unity in face of occupation, says academic

Asia Pacific Report

Sultan Barakat, a professor at Qatar’s Hamad Bin Khalifa University, says the release of Palestinian prisoners is a “symbolic win” rather than a victory for the Palestinians, primarily showing the inhumane conditions they live under.

“Israel can capture people in the West Bank and Gaza because they all live in a confinement area under the control of Israel,” he told Al Jazeera.

Dr Barakat discussed the way Palestinians were “arbitrarily rounded up, taken to prison and treated badly” by Israel.

A total of 183 Palestinian prisoners were released today from Israeli jails as part of the exchange for three Israeli hostages under the ceasefire deal between Hamas and Israel.

They included 18 serving life sentences and 54 serving lengthy sentences, as well as 111 detained in Gaza since 7 October 2023.

Dozens of Palestinians released from Israeli jails showed signs of torture and starvation, said the Palestinian Prisoner’s Society.

Barakat stressed that the release of prisoners also “shows the unity of the Palestinians in the face of occupation”.

“The prisoners are not all necessarily Hamas sympathisers — some were at odds with Hamas for a long time,” the academic said.

“But they are united in their refusal of occupation and standing up to Israel,” he added.

Hamas ‘needs to stay in power’
Another academic, Dr Luciano Zaccara, an associate professor at Qatar University’s Gulf Studies Center, told Al Jazeera that Hamas needed to stay in power for the ceasefire agreement to be implemented in full.

“How are you going to reconstruct Gaza without Hamas? How are you going to make this deal complied [with] if Hamas is not there?” he questioned.

Dr Zaccara also said Israel seemed to have no plan on what to do in Gaza after the war.

“There was never a plan,” he said, adding that Israel did not want Hamas or the Palestinian Authority in the enclave running the administration.

The Israeli newspaper Ha’aretz, quoting a security source, reported that the Red Cross had expressed “outrage” at how the Israel Prison Service handled the Palestinian prisoners being released from Ketziot Prison.

Ha’aretz said the Red Cross alleged that the prisoners were led handcuffed with their hands above their heads and bracelets with the inscription “Eternity does not forget”.

The newspaper quoted the Israel Prison Service spokesman as saying that “the prison warders are dealing with the worst of Israel’s enemies, and until the last moment on Israeli soil, they will be treated under prison-like rule.

“We will not compromise on the security of our people.”

Albanese will pitch to blue collar men with heavy warnings on Dutton’s workplace policies

Source: The Conversation (Au and NZ) – By Michelle Grattan, Professorial Fellow, University of Canberra

Prime Minister Anthony Albanese in conversation with Michelle Grattan.

Anthony Albanese has outlined his pitch to improve his and his government’s standing among men, as he insists he can hold onto majority government at the election to be held in April or May.

In a wide-ranging interview on The Conversation’s Politics podcast, canvassing both his plans and current issues, the Prime Minister addresses the gender voter gap the polls have been showing, which is worrying Labor strategists.

On a two-party basis, a December Essential poll had the Coalition on 51% among men, and Labor on 44%, with 4% undecided. Among women, Labor was on 49% and the Coalition on 46%, with 5% undecided.

In a Resolve poll on preferred prime minister, Peter Dutton polled 40% among men, and Albanese 34%. Among women, Albanese was on 36% and Dutton on 31%.

Albanese tells the podcast: “One of the things that we will be really campaigning very hard on is the impact on blue collar workers of the Coalition promises to get rid of same job, same pay [law], the definition of casual in employment [and] their plan to essentially go back to wages going backwards, not forwards.”

Targeting younger voters

As Labor crafts its election policy, Albanese also flags he is looking to do more for young people.

Asked who he feels is being “left behind” in Australia at the moment, he points to the issue of “intergenerational equity”.

“I think that young people feel like they’ve got the rough end of the pineapple compared with previous generations,” he says. This is “something I’m really conscious of”.

Outlining what the government has done or announced already on student debt, housing supply, schools, the universities accord and free TAFE, he suggests there will be further policies targeted towards younger voters.

The likeliest election dates

Albanese confirms he has not locked in an election date. “We make decisions when we finalise them and I’ll consult,” he says.

“But I’ve always said […] one of the problems with three year terms is that they are too short.”

The speculation is the election will be either April 12, or one of the first three Saturdays in May, with May 17 the last practical date.

April 12 would mean scrapping the scheduled March 25 budget. “We certainly are working to hand down a budget in March,” Albanese says. “The ERC [Expenditure Review Committee] will be meeting this week, as it met last week.”

Asked whether he is confident he could still deliver his program if the election resulted in a minority Labor government, Albanese says: “I’m confident that we can achieve an ongoing majority government at this election. I think there are seats that we currently hold that we have good prospects in.”

He names two Victorian Liberal seats he had just visited – Menzies and Deakin – among those he believes Labor can win from the Coalition. (After the redistribution, Menzies is notionally a Labor seat by a tiny margin.)

Watching for a rate cut and trade wars

Asked when Australia might come out of the present per capital recession, Albanese says things are “heading in a positive direction”, but does not nominate a time.

He sounds confident about interest rates falling soon:

All of the economic commentators are saying that that is the most likely prediction of markets. It’s not up to me as prime minister to tell the independent Reserve Bank what to do, but I’m certain that we have created the conditions through, as well as our responsible economic management, producing two budget surpluses – the massive turnaround that we have seen, compared with what the Morrison 2022 budget handed down by the Coalition […] was predicting.

Prompted about the Reserve Bank’s next meeting on February 18, he says “I’m certainly conscious of that date”.

With United States President Donald Trump slapping tariffs on Canada, Mexico and China while foreshadowing wider tariffs, Albanese recalls his phone conversation after Trump was elected, in which he reminded the incoming president that America has a trade surplus with Australia. Australia would “put our arguments forward very clearly” if it faced the threat of tariffs, Albanese says.

Looking ahead

Looking ahead to this fortnight’s parliamentary sitting, Albanese confirmed to The Conversation that he will not proceed with the Nature Positive legislation. It had been strongly opposed by the Western Australian government, which has its election on March 8.

But he hopes the Senate will pass the legislation for political donation and spending caps, indicating the government is willing to compromise to get the bill through.

Looking to a second term, Albanese highlights in particular the opportunities presented by the energy transition.

“We are positioned better than anywhere else in the world to benefit, in my view, from this transition that’s occurring.”

He contrasts Dutton’s energy plan, which he describes as a “myopic vision” to make Australia smaller.

“I want Australia to be more successful, to be enlarged in our optimism and our vision. And I want to lead a government that does that.”

What’s driving north Queensland’s deadly, record-breaking floods?

Record-breaking floods across north Queensland have now turned deadly, with one woman drowning while being rescued on Sunday morning. And the floodwaters are still rising, with rain set to continue.

Over the 48 hours to Sunday, there were reports of up to 1 metre of rainfall in parts of northeast Queensland. The torrential rain continues, particularly in the Herbert Coast region and north to around Tully.

Residents of Ingham and nearby towns, about 100km from Townsville, are witnessing flooding from the nearby Herbert River. This morning, it was at 15 metres and rising. With more heavy rain forecast for the next 24 hours, the Herbert River is likely to break the 1967 record of 15.2 metres later today.

Queensland Premier David Crisafulli – who grew up on his family’s sugar cane farm in Ingham – has said the floods will be a “once in a century” event for the town. To make matters worse, authorities say the town has lost power and an extended outage is likely.

The atmospheric factors behind these floods are very similar to recent floods in the region – and climate change is no doubt playing a role.

Where are the floods hitting?

For many people in Townsville – the largest city in Northern Australia – the unfolding emergency will bring back memories of the devastating February 2019 floods, which caused A$1.24 billion in damage. Residents have been asked to evacuate from several low-lying suburbs which were inundated in 2019.

It is too early to say if this flood event will be worse. Fortunately, water levels in the city’s Ross River Dam are much lower than 2019. Townsville Airport has recorded 545mm of rain over the past 48 hours, with many northwest suburbs recording much higher levels. The township of Rollingstone – 60km northwest of Townsville – recorded a whopping 702mm over the 24 hours to 9am Sunday.

Further north in the Cairns to Daintree region, residents are watching with concern, with many still raw after the record-breaking floods of December 2023.

What’s behind these floods?

The ongoing 2025 extreme rainfall event, the 2019 Townsville floods and the 2023 Cairns and Daintree floods are remarkably similar in many ways.

What triggered each of these floods was prolonged heavy rain falling on the southeast flank of a stationary tropical low weather system. Normally, tropical lows bring wind and rain, but move through quite quickly. But in recent years, we have seen a tendency for these systems to stall, sitting in place over or near land and dumping huge volumes of rain.

Last week, the Bureau of Meteorology warned that five tropical lows were forming around northern Australia. Most tropical cyclones form from tropical lows embedded in the region’s monsoon trough, a large low pressure band which forms over summer and draws in warm, moist air from the adjacent tropical seas.

But significant rain events like this one don’t necessarily require a tropical cyclone. Slow-moving deep monsoon lows over land can also deliver huge amounts of rain and widespread flooding.

These atmospheric conditions allow intense rain bands to form between converging winds: warm, moist winds from the northeast and southeast winds originating from the Coral Sea. As the winds collide, they push the moist air up into the cooler parts of the atmosphere where it condenses and falls as torrential rain.

More extreme rainfall and higher frequencies of flooded rivers and flash floods around the world have a clear link to climate change and ongoing global heating.

The main drivers behind these events include warming of the atmosphere. For every 1°C of warming, the atmosphere holds 7% more water vapour. Recent research suggests this figure could be even higher for short duration rainfall.

Hotter oceans hold more energy, meaning they can also amplify the global water cycle when atmospheric conditions are suitable.

This year’s latest ever monsoon

This year, sea surface temperatures in the northwest Coral Sea are 1-2°C above average. Ocean temperatures have risen because of a lack of cloud cover and rain last month. In northwestern Australia, this has given rise to an intensifying marine heatwave.

This ocean heat is likely to be driven by the Australian monsoon’s latest ever arrival. The monsoon brings heavy rains to northern Australia, triggering the wet season. When it arrives, sea surface temperatures generally drop due to a combination of high cloud cover and the cooling effect of rainwater.

After a slow start, the North Australian monsoon season is now in full swing.

The Bureau of Meteorology is monitoring an active monsoon trough for any low pressure systems, which may develop into tropical cyclones over the next week or so. If any cyclone does form, it will gain energy from warmer than usual sea surface temperatures.

What’s next for north Queensland?

The flood emergency in north Queensland is far from over. All global circulation models predict heavy rain to continue in the region, extending up towards Cape York and the Gulf Country as an active monsoon surge moves in from Indonesia.

As river catchments get saturated, more and more water will run off and engorge rivers. Forecasts are for rain to continue well into tonight and the next few days. We are likely to see more flooding in more places this week.
