Why your late teens and early 20s are crucial times for lifelong heart health

Emerging adulthood – the life stage that unfolds around ages 18-25 – is full of major transitions, such as starting college or learning a trade, making new friends and romantic connections, and generally becoming more independent.

It’s also a stage where behaviors that diminish heart health, such as spending more time sitting, consuming more fast food and using more tobacco and alcohol, become more common. In fact, only about 1 in 4 youths maintain positive health behavior patterns during the transition to adulthood.

More Americans die of heart disease than of any other condition. People often think of heart disease as an illness that mostly affects older people, but data from electronic health records show that the rate of heart disease in people under 40 has more than doubled since 2010 and tripled among people who use tobacco. Researchers like me are learning a great deal more about how heart health later in life heavily depends on the habits built during late adolescence and early adulthood.

I am a primary care nurse practitioner and researcher studying how early life shapes long-term heart health. In my clinical practice, I frequently care for people in their early 20s who are entering adulthood and are already facing serious cardiovascular risk factors such as elevated blood pressure, high blood sugar or a body mass index in the obesity range.

Just as young people on the cusp of adulthood make important decisions about their education, career and relationships, the health habits they build during this critical time also lay the foundation for lifelong heart health and better quality of life.

Early roots of heart disease

The most common form of heart disease is atherosclerotic cardiovascular disease, which develops when sticky, fatty plaque builds up in the blood vessels and makes it harder for blood to flow.

Heart health doesn’t suddenly decline in middle age. It starts to slip much earlier, often without people realizing it. In fact, research shows that a key turning point is around age 17. That’s when overall heart health scores based on behaviors such as diet, movement and sleep, along with clinical measures such as blood pressure, begin to worsen.

Age 17 is a key turning point when heart health scores can begin to decline in young people.

That means by the time many young people are finishing high school, heart disease risk factors are already emerging. The good news is that most of the risk factors that drive this buildup are modifiable – meaning you can do something about them.

In a report I co-authored in March 2025, my colleagues and I explored the key risk factors for heart disease in emerging adults. One of the most important is nicotine exposure. Use of cigarettes, vapes and other nicotine products has surged among young adults in recent years, from 21% of 18- to 23-year-olds in 2002 to 43% in 2018. Nicotine damages blood vessels and speeds up the plaque formation process, increasing the risk of serious heart problems later in life. While signs such as chest discomfort or shortness of breath tend to show up much later, the groundwork for those symptoms is laid much earlier.

Obesity is another early risk factor. In fact, 1 in 5 young people under age 25 have a BMI of 30 or higher, and projections suggest nearly 3 in 5 will meet that threshold by age 35.

Meanwhile, fewer than half of adults ages 18-34 recognize high cholesterol, obesity, high blood pressure and lack of physical activity as heart disease risk factors. These early warning signs, often uncovered during routine checkups, can set the stage for future heart disease.

Societal factors shape heart health, too

Heart health isn’t shaped by individual choices alone. Broader policies and systems also play a major role.

For example, the Affordable Care Act allows young adults to stay on their parents’ insurance plans until age 26, which can help ensure access to preventive services. These services, such as routine checkups, blood pressure screenings and conversations about family history, are key opportunities for your primary care provider to catch early signs of cardiovascular risk.

While preventive care use among young adults increased after the ACA was passed, overall rates of preventive care visits still remain low. Policies that expand access to health care and that make it easy for young people to take advantage of these services, such as telehealth, can make a real difference. And if a provider doesn’t bring up heart health during a well-check visit, patients can ask questions or start the conversation themselves.

Beyond health care access, the conditions of people’s daily lives, such as where they live, their education level and their economic stability, also play important roles in heart health. Neighborhoods can include resources such as parks and green spaces, which make healthy choices more feasible. Education and stable employment are tied to health care access, lower stress and food security, all of which support a healthier heart.

Healthy social connections matter, too. Strong, supportive relationships are linked to better overall well-being, including heart health. Recently, several major health organizations have spotlighted loneliness as a public health issue. However, there is still a lot to learn about exactly how social connections translate to healthier lives, and not enough of this research focuses on young adults.

Pew research shows that 1 in 3 teens report near-constant use of social media, but those connections do not yield the same health benefits as interacting in real life. In my own research, I am investigating how social connection affects heart health in young adults in particular.

Building a foundation for heart health

There is a lot you can do today to make a difference in your heart health. In our recent report, written with the American Heart Association, my colleagues and I highlighted a group of eight risk factors that people can modify to reduce their heart disease risk, called the Essential 8.

Embracing the Essential 8, a set of evidence-based measures developed by the American Heart Association, can help young people establish lifelong habits for a healthy heart.

Four are health behaviors. In addition to avoiding nicotine, young people should prioritize getting 150 minutes of moderate to vigorous activity a week, or around 20 minutes a day, as recommended by the American Heart Association. They should also aim to get seven to nine hours of sleep nightly and to eat a diet rich in fish, berries and vegetables. Even small changes in these four behaviors can have positive effects.

Of these four behaviors, U.S. children score worst on diet – an important area for improvement in the transition to adulthood. Young adults with stronger cooking skills tend to have healthier eating habits in middle age, suggesting that learning how to cook could be a valuable step toward better heart health.

The other four factors are clinical measures: blood pressure, blood sugar, cholesterol and BMI. Since the early 2000s, three of the four – blood pressure, blood sugar and BMI – have all worsened among young adults.

These changes can go unnoticed until much later, but checking in on them early creates an opportunity to take action. The next time you are at a checkup, ask your provider about your heart health – even if you think you’re too young to be worrying about heart disease. A simple conversation today could shape the way you feel years from now, and your future heart will thank you.

Syria’s new leader promised democracy. Then he excluded women from parliamentary elections

Source: The Conversation – Global Perspectives – By Kinda Alsamara, Lecturer in the School of Languages and Cultures, The University of Queensland

Women’s political participation is often treated as a measure of a country’s commitment to equality and democracy.

Earlier this year, Syria’s new leader, President Ahmed al-Sharaa, described his country as moving in a “democratic direction” after the fall of Bashar al-Assad’s dictatorship in late 2024. He said:

If democracy means that the people decide who will rule them and who represents them in the parliament, then, yes, Syria is going in this direction.

Yet, in Syria’s recent parliamentary elections, women only won six seats in the 210-member body. Exclusion was not merely reflected in the outcome, it was engineered into the very structure of the process.

A long history of marginalisation

Assad ruled Syria with an iron fist for more than two decades through widespread repression, war crimes and systematic violence against civilians.

Parliamentary elections were highly controlled, with Assad’s Ba’ath Party and its allies dominating every vote. Women held between 6% and 13% of seats from 1981 to the end of Assad’s tenure, according to estimates from a global organisation of national parliaments.

Although the parliament had little real power, it served to legitimise Assad’s rule through the appearance of a democratic process.

In December 2024, al-Sharaa’s Islamist-led coalition took advantage of the power vacuum created by the decline of Iran’s regional influence and the collapse of its allied armed groups to oust Assad and dissolve Syria’s symbolic legislature.

Al-Sharaa’s rise was initially hailed as a potential turning point toward political reform and reconciliation. However, early signs suggest that entrenched patterns of marginalisation – especially of women – are continuing to shape Syria’s politics.

How women (and others) were sidelined

The recent parliamentary elections in early October did not factor in the people’s will, nor were they permitted to vote. They weren’t involved in the process at all.

Instead, the elections were overseen by a government body called the Supreme Judicial Committee for Elections, appointed by al-Sharaa. Its composition was revealing: nine men and only two women.

The process was complicated and deliberately exclusionary. The Supreme Judicial Committee was tasked with forming electoral subcommittees around the country, which then reviewed applicants for individuals to be appointed to electoral colleges. Only those selected were allowed to participate in the voting process or nominate candidates.

Ordinary citizens had no direct role in the election.

Under this framework, the electoral colleges selected representatives for two-thirds of the parliament seats. Al-Sharaa will appoint the remaining third.

Unsurprisingly, women’s representation in the subcommittees was minimal. Drawing on raw figures published on the official Syrian election website, women only constituted about 11% of all subcommittee members (18 out of roughly 180 nationwide).

Even where women did have decent representation, no female parliamentarians were elected. In Damascus, for example, women comprised nearly a third of the registered applicants (44 out of 145) for the electoral college and a third of the local subcommittee members. Yet, not a single woman from the capital was elected.

Minority representation was also limited. Of the 119 members elected so far, only ten belong to religious or ethnic minorities, including Kurds, Alawites and Christians (who won just two seats). Christians are believed to make up 10% of Syria’s 24 million population.

Previous research on gender and political institutions has shown that exclusionary electoral structures tend to produce exclusionary outcomes. Syria’s case fits this broader pattern.

Syrian officials have explained women’s exclusion as a cultural matter. Mohammad Taha al-Ahmad, the head of the Supreme Judicial Committee for Elections, appeared on television to express “surprise” at the low number of female candidates, attributing it a society that traditionally views politics as the domain of men. He said the results also reflected alliances (based on established male networks) that formed among members of the subcommittees.

While such attitudes undoubtedly shape gender dynamics, they cannot by themselves account for the low participation of women in the election.

Women were constrained from the outset. Invoking “culture” shifts the blame away from the institutional barriers.

Ultimately, this was not a free or fair election. When women’s involvement is reduced to symbolic inclusion under state supervision, elections cease to be instruments of representation and become performances of legitimacy.

What can be done?

Reversing this pattern requires more than rhetoric. There must be institutional reform, including:

  • gender quotas that reserve a proportion of candidacies or seats for women, allowing them to gain political experience and visibility

  • increased funding, training and local networking initiatives to help women build community-based constituencies

  • reforming electoral processes to move toward more direct, transparent voting that limits alliances among elites and presidential control

  • instituting new school curricula and civil society programs that normalise women’s participation in public life and challenge gendered perceptions of political leadership.

Until such reforms are enacted, Syria’s elections will continue to reflect not popular will, but the entrenched hierarchies of a state that governs through exclusion.

How damaging to the royal family is the scandal surrounding Prince Andrew?

Source: The Conversation – Global Perspectives – By Dennis Altman, Vice Chancellor’s Fellow and Professorial Fellow, Institute for Human Security and Social Change, La Trobe University

The latest allegations against Prince Andrew, in Virginia Giuffre’s book Nobody’s Girl, and reports that he and his wife, the Duchess of York, maintained contact with Jeffrey Epstein after his conviction for soliciting prostitution from a minor, present an ongoing problem for the royal family.

Giuffre, who died by suicide earlier this year, accused Andrew of sexually assaulting her on three occasions when she was 17. He has repeatedly denied the accusations.

King Charles moved swiftly, ordering his brother to forsake both his title of royal highness and surrender the other orders of nobility that are bestowed on children of the monarch, whether deserved or not.

The removal of royal titles from Prince Andrew – still his name – is hardly the first time the royals have been ruthless in pursuit of respectability. Like other royal families who have survived into the 21st century, they combine celebrity with a keen sense of self-preservation.

History suggests that when scandal strikes, the royal instinct is to remove embarrassments from public view. This is more difficult when dealing with adults in an era of celebrity journalism. When Prince John, son of George V (who was king from 1910-1936), was found to be epileptic, he was carefully removed from public view and even from contact with his family. John died aged 14 and is largely forgotten.

More distressing was the revelation through a television documentary that two cousins of Queen Elizabeth II who had intellectual disabilities were institutionalised and ignored by the family, although the palace has denied this.

But these are minor examples compared to the scandals surrounding the abdication of Edward VIII, the refusal to allow Princess Margaret to marry Peter Townsend and the very public exile of Prince Harry to California. It seems the second in line to the throne has a peculiarly troubled life, as Prince Harry made clear in his memoir, Spare.

Those scandals all revolved around unsuitable marriages: Edward abdicated when he was forbidden to marry Wallis Simpson; Margaret finally married Tony Armstrong Jones and subsequently divorced him; Harry’s defection from Britain was the direct consequence of his marriage to Meghan Markle.

But whereas Edward could not marry a divorced woman, Charles divorced Diana while heir to the throne and after her death married his long-time mistress, Camilla. In time, Camilla has gone from being excoriated as “the other woman” to a widely accepted queen.

One has to go back a century at least to find a royal prince whose alleged behaviour is so clearly reprehensible – and presumably criminal – as that of Andrew. That he has escaped prosecution is itself troubling, although he paid Guiffre a very considerable settlement while maintaining his total innocence.

Like Harry, Andrew can only be removed from the line of succession by an act of parliament, but he is, after all, only eighth in line to the throne. The king has clearly decided Andrew will no longer be part of the official royal family, unlike his other siblings Anne and Edward.

Perhaps luckily, the prince cannot be shipped off to become a colonial governor, as was the fate of the Duke of Windsor during the second world war. Andrew will presumably be left to his own devices in the grounds of Windsor Castle, banished from family gatherings, which are always at the mercy of the paparazzi.

Hard questions may be asked about the cost to the British taxpayer of maintaining Andrew and Sarah, who live in a luxurious lodge and presumably are well cared for by servants. The British public seem largely unconcerned at the cost of maintaining even non-working members of “the firm”, rather as Australians rarely question the cost of maintaining seven vice-regal residences to maintain the fiction we are a monarchy.

Will this scandal affect the position of the royals? Almost certainly not: in Britain, as in Australia, the enthusiasm for abandoning constitutional monarchy appears to be declining. People can separate their outrage at Andrew from their respect for the monarchy, which is helped by the rise of populist autocrats such as US President Donald Trump.

When Trump visited Britain last month, he was a guest of Charles, who used his role as head of state consummately to flatter Trump with pomp and ceremony, while making clear he did not endorse all his positions.

With the popular William and Kate patiently waiting their turn, the British monarchy is likely to manage even a scandal as great as this one.

Ange Postecoglou’s sackings may say more about the Premier League’s attention span than him

Source: The Conversation – Global Perspectives – By Scott McLean, Adjunct Associate Professor, University of the Sunshine Coast

Ange Postecoglou has been sacked by two Premier League clubs in four months: Tottenham Hotspur in June (two weeks after winning the Europa League), then Nottingham Forest in October after just 40 days and eight games (with six losses and two draws).

His time at Forest was the shortest non-interim reign in Premier League history.

The Premier League’s average tenure for managers is short and trending shorter, currently around two years.

Remove the combined 15 years of Pep Guardiola (nine years at Manchester City), and Mikel Arteta (six years at Arsenal), and that two-year average plummets for the remaining 18 managers, highlighting a league-level state of constant reset.

So, what does Postecoglou’s latest sacking say about his coaching style, and the team owners and boards who make these decisions?

What is ‘Ange-ball’?

Postecoglou’s playing style, nicknamed “Ange-ball”, is brave, attacking and high-intensity.

It is a style that has delivered multiple league titles and cups across three continents – Australia, Asia and Europe – and the 2015 Asian Cup with the Australian national team.

With the ball, Postecoglou uses “inverted full-backs” (left- and right-sided defenders who can move into midfield to create a numerical advantage), and prioritises quick passes and build-up play from the back rather than playing the ball long.

Without the ball, his sides press high up the field and try to win it back fast, accepting risk in the space left behind the high defensive line.

It’s exciting and effective when executed properly, but is vulnerable if personnel don’t fit key positions or if players are still learning their roles.

It was these vulnerabilities that may have proved his downfall.

Was Nottingham Forest a great fit?

Nuno Espírito Santo, the manager Postecoglou took over from at Forest, was the opposite to “Ange-ball”.

His team was comfortable sitting behind the ball with a compact shape and lower defensive block. With the ball, he prioritised quick and direct counterattacks and a threat at set-pieces (such as corners and free kicks).

Essentially, it was a “minimise chaos” model.

Swapping to Postecoglou’s controlled chaos overnight is like taking a fleet of delivery vans to a Formula One grid.

Which begs a basic question: if Forest wanted instant results, was Postecoglou the right choice for a squad that was recruited and set up to play a contrasting style?

If you change any operating system, you must accept a period of bugs.

Postecoglou’s method asks for lightning-quick centre-backs, midfielders who can resist pressure and keep the ball, and full-backs who can step into midfield.

If you haven’t recruited for that and you don’t allow time for players to learn it, you’re setting the coach up to fail.

It’s telling that £120 million (A$247 million) of Forest’s summer signings were not included in Postecoglou’s final team selection.

Systems change is behaviour change. It needs repetition, role clarity, and a bit of psychological safety.

None of that happens in a few weeks.

Is Postecoglou’s style unsustainable?

Elite sport is a performance business and Postecoglou’s performances were deemed untenable at both Spurs and Forest.

But do proactive coaches like Postecoglou succeed at the very highest level?

Yes, when clubs support the vision. Pep Guardiola’s Manchester City, Mikel Arteta’s Arsenal and Roberto De Zerbi’s (former) Brighton all play with brave positioning, pressing and attack-minded structures.

Further, they recruit or develop players who fit that philosophy.

Postecoglou was mostly unwavering in his risk-and-reward style, yet he showed he could adapt. He won the Europa League by playing a more measured and defensive style.

Ultimately, after two years in charge at Tottenham, he was let go after a poor Premier League finish.

Nottingham Forest sacked him minutes after a 3–0 loss to Chelsea, before the players could even take their boots off, let alone settle into their new roles.

Owners, control, and the ‘do something’ button

Sacking a coach provides a visible lever, a perceived control mechanism that calms headlines and fan unrest, even though research on managerial turnover shows in-season changes don’t always generate improvements and can increase performance variance in the short term.

In other words, you might get a brief “new manager bounce” but you also amplify unwanted noise.

In the business world, a new chief executive needs roughly 18 months to show a transformation is working, and about two to three years to complete a full turnaround. And this assumes they can assemble the right team in their first six to nine months, and the board stays the course.

If global businesses give leaders time to show a plan is working, then sacking a football manager after a handful of games isn’t “elite standards” – it’s absurd.

Either club owners need to rethink their timelines, or they should stop pretending they want real transformation at all.

If owners want true transformation, they must resist reaching for the “do something” button at the first bump and tolerate some initial mess.

Where to from here?

No one more than Postecoglou will understand that from a league results standpoint, he failed at both Spurs and Forest.

Perhaps his full-throttle approach in the world’s toughest league was naive.

It’s hard to know whether other clubs will be put off by these recent sackings and Postecoglou still has a place in top-level management. Time will tell.

What will happen to the Louvre jewellery after the heist? There are two likely scenarios

Source: The Conversation – Global Perspectives – By Andreas Schloenhardt, Professor of Criminal Law, The University of Queensland

Zhang Weiguo/VCG via Getty Images

The spectacular heist of jewellery from the Louvre museum in Paris has many people wondering how a theft like this could occur in broad daylight and what might happen to the items that were stolen from the museum.

In a matter of minutes, four thieves were able to enter through a first-floor window, break into secure glass displays, and take nine items of jewellery of immeasurable value.

Although an alarm was set off and museum guards were nearby, the thieves were able to escape quickly, using motor bikes to get away. They dropped one stolen item, a diamond and emerald-encrusted royal crown that had belonged to Empress Eugénie, Napoleon III’s wife.

Their loot include jewellery from French imperial times – brooches, necklaces, earrings and a tiara. The French prosecutor’s office said the jewels were worth some 88 million euros (A$157 million), not including their historical value.

The speed and professionalism of the heist shows this was a well-planned crime, carried out by highly skilled perpetrators. That suggests they are linked to organised criminal groups.

Several media outlets reported a number of smaller thefts from French museums in recent weeks, including gold nuggets from the Paris Natural History Museum. There is no suggestion these thefts were linked to the Louvre heist.

What might happen to the loot?

The stolen jewellery includes well-known pieces that are easily recognisable. This will make it difficult, if not impossible, to sell them on the black market, even to well-heeled collectors and buyers.

This problem is well-known from other museum heists – such as the theft of the Canadian “Big Maple Leaf” giant gold coin from Berlin’s Bode Museum in 2017 or the famous heist of 13 masterpieces by Degas, Manet and Rembrandt from the Isabella Stewart Gardner Museum in Boston in 1990. Those paintings have never been recovered.

Instead, most experts believe one of two scenarios are more likely.

In the first, the jewellery would be broken down into smaller pieces. Diamonds and other gemstones may be taken out, altered and then offered for sale. Silver and gold may be used to manufacture other pieces or may be sold separately.

This scenario would make it easy to conceal the origin of the pieces and sell them openly or online. The combined value, however, would be significantly lower compared to leaving the pieces intact. It is thus doubtful the thieves targeted the specific jewellery for this purpose.

Scenario two would involve the thieves, or more likely the masterminds behind them, trying to sell the pieces back to the Louvre or trying to extort money from the French government for their return.

This may be done through brokers or other middlemen and may not happen for a while, until there is less public and media attention and the perpetrators feel sufficiently safe to contact – directly or indirectly – museum or state authorities.

Given the historical significance of the pieces coupled with the embarrassment caused by the heist, the Louvre and the French government would be keen to have the pieces returned as swiftly as possible and might be willing to negotiate, albeit secretively.

Much of this remains, however, speculation. Only a few days have passed since the heist occurred and many questions about the events, perpetrators and their motives remain unanswered. And just who may be behind this spectacular heist from France’s largest museum has everyone guessing.

Similarities with a Dresden museum heist

The Louvre theft brings to mind the jewellery heist at the Green Vault at the Zwinger Palace in Dresden, Germany, in 2019.

In this case, the perpetrators had closely examined the museum’s security system for many days and were able to enter the building without being caught on camera. They entered through a window on the first floor and within minutes stole 21 pieces of jewellery from several displays.

Unlike the Paris heist, the Dresden thieves entered at night and used brute force to damage the displays to take their loot.

Some years after the robbery, German authorities were able to identify and arrest the thieves involved in the heist – all five were members of a notorious Berlin-based crime family.

The perpetrators have since been tried and convicted and are serving long jail times. Most of the jewellery was retrieved and returned – unaltered – to its famous home.

It is hoped the French authorities will soon be similarly successful.

Japan’s economy needs foreign workers, not the nationalist approach pushed by its new leader

Source: The Conversation – Global Perspectives – By Adam Simpson, Visiting Scholar at the Center for Southeast Asian Studies, Kyoto University; Senior Lecturer, International Studies, University of South Australia

Sanae Takaichi has made history by becoming Japan’s first female prime minister. However, this was hardly a win for feminist or progressive politics.

Takaichi is a right-wing ultraconservative whose policy positions derive from traditionalist perspectives on the role of women, Japanese history and society more broadly.

She has the same anti-immigrant positions as conservatives and right-wing populists the world over, defending “national identity and traditional values”, while emphasising the importance of strong economic growth.

Far from solving Japan’s economic problems, however, policies that restrict immigration tend to cause labour shortages and inflation.

Japan is the canary in the coalmine for many developed countries suffering a
demographic crisis due to falling birth rates. Japan’s population has declined for 16 consecutive years.

Unless Takaichi adopts a more pragmatic approach on immigration, her tenure could be one of economic stasis and relative decline.

How did Takaichi become prime minister?

Takaichi was elected leader of the ruling Liberal Democratic Party earlier this month. Her rise to prime minister was delayed, however, when the LDP’s junior partner, the Komeito party, withdrew from the governing coalition over the LDP’s handling of a political funding scandal.

The LDP has minorities in both the upper and lower houses of Japan’s Diet, or parliament, and requires coalition partners to govern.

After extensive negotiations that will require compromises from all sides, the right-wing Japan Innovation Party, known as Ishin, agreed to support Takaichi and her LDP-led government.

However, the new coalition is still two seats short of a majority in the lower house and will require additional parliamentary support. This means Takaichi’s minority government will be more precarious and constrained than previous governments.

Japan’s demographic crisis

Japan’s population peaked at around 128 million in 2008 and has steadily declined ever since. It’s around 124 million today.

Last year, the fertility rate (the average number of children a woman has in her lifetime) fell to a record low of 1.15.

Under current projections, Japan’s population is expected to fall to 87 million by 2070 and 63 million by 2100, when only half the population will be of working age.

The issue is therefore not simply one of a declining population, but also an ageing population, with rising pension and medical costs. Many professions in Japan, such as teachers, doctors and caregivers, are already facing acute labour shortages.

Immigration as a political lightning rod

While previous governments have acknowledged the declining population is a significant problem, they have done little to address the issue. Various initiatives have brought foreign residents or workers into the country, but there has been a reluctance under LDP governments to introduce programs with the scale and commitment – in terms of integrating immigrants into Japanese society – to make a significant difference.

This means these programs have had only modest success. Japan’s number of foreign-born residents reached a record high of 3.6 million this year, representing around 3% of the population. But this is far lower than many other developed economies.

This increased foreign population has resulted in a record number of “foreign” babies being born in Japan, with Chinese, Filipino and Brazilian mothers topping the list. This has somewhat offset the
declining figures for newborns from Japanese parents.

Japan’s tourism industry is also booming, with almost 37 million visitors coming last year.

Taken together, this increasing number of foreigners in Japan has resulted in the rise of anti-immigrant parties and policies, including the far-right Sanseito party. This, in turn, prompted the LDP to move further to the right to avoid losing votes to Sanseito and other populist parties.

This partly explains why Takaichi’s nationalist rhetoric has resonated with the ageing conservative LDP base.

Takaichi advocates for foreign workers in specified fields where the country has labour shortages, albeit under strict criteria (such as Japanese language ability, training and oversight). And she opposes the mass settlement of immigrants, or the large-scale granting of political rights to foreign residents.

While her policies have so far been short on detail, she has framed foreigners as a danger to national cohesion that needs to be strictly controlled.

Pro-natalist policies pushed instead

Across the world, older populations tend to be more susceptible to anti-immigrant scare campaigns from right-wing conservative media and politicians.

Japan is no exception. Politicians such as Takaichi, therefore, see electoral benefits in colouring immigration and foreigners as a threat to social harmony or cultural heritage.

Unfortunately, as a result, ageing countries like Japan that are most in need of immigration are often the most resistant to it.

Instead, many right-wing conservatives in these countries promote pro-natalist policies – encouraging women from the dominant racial or ethnic group to have more babies – as a solution that boosts populations and maintains cultural and racial homogeneity.

Hungary is one such example. The right-wing nationalist government of Viktor Orban has provided generous financial benefits to parents at a cost of around 5% of Hungary’s GDP. Though Hungary’s birth rate was above the European average in 2023, it has fallen since then.

Conservatives are pushing Japan to take a similar pro-natalist approach rather than rely on increased immigration.

With Takaichi as prime minister, Japan is unlikely to see an improvement in women’s independence and status in society, a significant rise in birth rates, or increased immigration. Japan’s demographic crisis is therefore set to continue, and probably worsen, in the foreseeable future.

How to ensure youth, parents, educators and tech companies are on the same page on AI

Source: The Conversation – Canada – By Ajay Kumar Shrestha, Professor, Computer Science, Vancouver Island University

Artificial intelligence is now part of everyday life. It’s in our phones, schools and homes. For young people, AI shapes how they learn, connect and express themselves. But it also raises real concerns about privacy, fairness and control.

AI systems often promise personalization and convenience. But behind the scenes, they collect vast amounts of personal data, make predictions and influence behaviour, without clear rules or consent.

This is especially troubling for youth, who are often left out of conversations about how AI systems are built and governed.

The author’s guide on how to protect youth privacy in an AI world.

Concerns about privacy

My research team conducted national research and heard from youth aged 16 to 19 who use AI daily – on social media, in classrooms and in online games.

They told us they want the benefits of AI, but not at the cost of their privacy. While they value tailored content and smart recommendations, they feel uneasy about what happens to their data.

Many expressed concern about who owns their information, how it is used and whether they can ever take it back. They are frustrated by long privacy policies, hidden settings and the sense that you need to be a tech expert just to protect yourself.

As one participant said:

“I am mainly concerned about what data is being taken and how it is used. We often aren’t informed clearly.”

Uncomfortable sharing their data

Young people were the most uncomfortable group when it came to sharing personal data with AI. Even when they got something in return, like convenience or customization, they didn’t trust what would happen next. Many worried about being watched, tracked or categorized in ways they can’t see.

This goes beyond technical risks. It’s about how it feels to be constantly analyzed and predicted by systems you can’t question or understand.

AI doesn’t just collect data, it draws conclusions, shapes online experiences, and influences choices. That can feel like manipulation.

Parents and teachers are concerned

Adults (educators and parents) in our study shared similar concerns. They want better safeguards and stronger rules.

But many admitted they struggle to keep up with how fast AI is moving. They often don’t feel confident helping youth make smart choices about data and privacy.

Some saw this as a gap in digital education. Others pointed to the need for plain-language explanations and more transparency from the tech companies that build and deploy AI systems.

Professionals focus on tools, not people

The study found AI professionals approach these challenges differently. They think about privacy in technical terms such as encryption, data minimization and compliance.

While these are important, they don’t always align with what youth and educators care about: trust, control and the right to understand what’s going on.

Companies often see privacy as a trade-off for innovation. They value efficiency and performance and tend to trust technical solutions over user input. That can leave out key concerns from the people most affected, especially young users.

Power and control lie elsewhere

AI professionals, parents and educators influence how AI is used. But the biggest decisions happen elsewhere. Powerful tech companies design most digital platforms and decide what data is collected, how systems work and what choices users see.

Even when professional push for safer practices, they work within systems they did not build. Weak privacy laws and limited enforcement mean that control over data and design stays with a few companies.

This makes transparency and holding platforms accountable even more difficult.

What’s missing? A shared understanding

Right now, youth, parents, educators and tech companies are not on the same page. Young people want control, parents want protection and professionals want scalability.

These goals often clash, and without a shared vision, privacy rules are inconsistent, hard to enforce or simply ignored.

Our research shows that ethical AI governance can’t be solved by one group alone. We need to bring youth, families, educators and experts together to shape the future of AI.

The PEA-AI model

To guide this process, we developed a framework called PEA-AI: Privacy–Ethics Alignment in Artificial Intelligence. It helps identify where values collide and how to move forward. The model highlights four key tensions:

1. Control versus trust: Youth want autonomy. Developers want reliability. We need systems that support both.

2. Transparency versus perception: What counts as “clear” to experts often feels confusing to users.

3. Parental oversight versus youth voice: Policies must balance protection with respect for youth agency.

4. Education versus awareness gaps: We can’t expect youth to make informed choices without better tools and support.

What can be done?

Our research points to six practical steps:

1. Simplify consent. Use short, visual, plain-language forms. Let youth update settings regularly.

2. Design for privacy. Minimize data collection. Make dashboards that show users what’s being stored.

3. Explain the systems. Provide clear, non-technical explanations of how AI works, especially when used in schools.

4. Hold systems accountable. Run audits, allow feedback and create ways for users to report harm.

5. Teach privacy. Bring AI literacy into classrooms. Train teachers and involve parents.

6. Share power. Include youth in tech policy decisions. Build systems with them, not just for them.

AI can be a powerful tool for learning and connection, but it must be built with care. Right now, our research suggests young people don’t feel in control of how AI sees them, uses their data or shapes their world.

Ethical AI starts with listening. If we want digital systems to be fair, safe and trusted, we must give youth a seat at the table and treat their voices as essential, not optional.

A flexible lens controlled by light-activated artificial muscles promises to let soft machines see

Inspired by the human eye, our biomedical engineering lab at Georgia Tech has designed an adaptive lens made of soft, light-responsive, tissuelike materials.

Adjustable camera systems usually require a set of bulky, moving, solid lenses and a pupil in front of a camera chip to adjust focus and intensity. In contrast, human eyes perform these same functions using soft, flexible tissues in a highly compact form.

Our lens, called the photo-responsive hydrogel soft lens, or PHySL, replaces rigid components with soft polymers acting as artificial muscles. The polymers are composed of a hydrogel − a water-based polymer material. This hydrogel muscle changes the shape of a soft lens to alter the lens’s focal length, a mechanism analogous to the ciliary muscles in the human eye.

The hydrogel material contracts in response to light, allowing us to control the lens without touching it by projecting light onto its surface. This property also allows us to finely control the shape of the lens by selectively illuminating different parts of the hydrogel. By eliminating rigid optics and structures, our system is flexible and compliant, making it more durable and safer in contact with the body.

Why it matters

Artificial vision using cameras is commonplace in a variety of technological systems, including robots and medical tools. The optics needed to form a visual system are still typically restricted to rigid materials using electric power. This limitation presents a challenge for emerging fields, including soft robotics and biomedical tools that integrate soft materials into flexible, low-power and autonomous systems. Our soft lens is particularly suitable for this task.

Soft robots are machines made with compliant materials and structures, taking inspiration from animals. This additional flexibility makes them more durable and adaptive. Researchers are using the technology to develop surgical endoscopes, grippers for handling delicate objects and robots for navigating environments that are difficult for rigid robots.

The same principles apply to biomedical tools. Tissuelike materials can soften the interface between body and machine, making biomedical tools safer by making them move with the body. These include skinlike wearable sensors and hydrogel-coated implants.

What other research is being done in this field

This work merges concepts from tunable optics and soft “smart” materials. While these materials are often used to create soft actuators – parts of machines that move – such as grippers or propulsors, their application in optical systems has faced challenges.

Many existing soft lens designs depend on liquid-filled pouches or actuators requiring electronics. These factors can increase complexity or limit their use in delicate or untethered systems. Our light-activated design offers a simpler, electronics-free alternative.

What’s next

We aim to improve the performance of the system using advances in hydrogel materials. New research has yielded several types of stimuli-responsive hydrogels with faster and more powerful contraction abilities. We aim to incorporate the latest material developments to improve the physical capabilities of the photo-responsive hydrogel soft lens.

We also aim to show its practical use in new types of camera systems. In our current work, we developed a proof-of-concept, electronics-free camera using our soft lens and a custom light-activated, microfluidic chip. We plan to incorporate this system into a soft robot to give it electronics-free vision. This system would be a significant demonstration for the potential of our design to enable new types of soft visual sensing.

The Research Brief is a short take on interesting academic work.

Through role-play learning, a neurodivergent student found work practicum success

Source: The Conversation – Canada – By Kealey Dube, Assistant Professor, The School of Social Work, MacEwan University

When students move from university course work to real-world applications like internships, practicums or clinical placements, it’s not just about what they know, but how they use what they know.

These experiences are often the first time students apply classroom learning in unpredictable, high-stakes environments.

For students with disabilities, that leap can be especially challenging. Structural barriers, inaccessible learning environments and past negative experiences can make these transitions harder.

Something that can help students overcome barriers is simulation-based learning — when, via role playing, students practise key skills, try out strategies and learn from mistakes without the real-world consequences. It’s an approach practised across fields like health care, business as well as social work education.

We decided to explore the use of simulations with students who experience disability-related barriers, drawing on research related to learning through simulations and students with disabilities in practicum learning.

From participants to partners

We took a “students as partners” approach, which sees students as active collaborators in designing their own learning experiences.

In this case study, we sought to design simulations that were practical, empowering and suited to a neurodiverse, social work university student. We also wanted simulations that reflected his particular concerns and were grounded in his unique lived experiences.

The student had experienced barriers in a previous work-integrated learning placement. Before starting another, he needed a safer way to build confidence, practise communication and prepare for the professional environment.

A team approach

The project was collaborative. As faculty members, we worked with the social work student involved in the field education course and a theatre student hired as our partner to co-create the simulations. Other participants were from MacEwan’s access and disability resources and the Centre for Teaching and Learning.

Together, the group co-designed two tailored, realistic simulation experiences aimed at helping the social work student prepare for his upcoming practicum.

How it worked

The team met over a summer to co-design the personalized simulations:

  • A workplace conversation, where the student practised setting expectations with a supervisor.

  • A client-facing scenario, where he responded to a phone inquiry — something he was likely to encounter during his placement.

Each simulation followed a three-part process:

  • Briefing: The student reviewed the context and goals.

  • Role play: The theatre student played a realistic role based on the scenario.

  • Debrief: The student watched a video of the simulation, reflected on what worked, and received supportive feedback.

By repeating the simulations multiple times, the students could build skills gradually, adjust strategies and become more confident with each try.

The theatre student also gained valuable experience learning and practising how to respond authentically and adapt during unscripted moments — skills that carry over to his own performance training.

What changed

When determining learning goals for the simulation, we focused on aligning course learning outcomes with needs specific to the social work student, such as communication skills. With each role play rotation, we captured how long it took for the social work student to clearly communicate his question or reflection to the client (played by the theatre student).

The amount of time decreased each rotation. By the end, the social work student reported he felt more confident moving through the situations. He became quicker, more confident and more comfortable with professional communication.

Most importantly, he reported feeling included and respected throughout the process. He said:

“Being involved in everything helped me feel more prepared. I made mistakes in the simulation and learned from them — so I didn’t have to make those same mistakes in real life.”

The theatre student echoed this:

“I wasn’t just acting — I was helping someone grow. It made me realize how powerful theatre can be beyond performance.”

Beyond skill development, this was capacity-building, confidence-building and community-building — all made possible by student-centred design. A year later, the student with a disability has successfully completed two field practicums and has graduated.

Why it matters

When universities design learning experiences with students, not just for them — especially students who are often left out of the process, like students facing disability-related barriers — opportunties for student engagement and empowerment are strengthened.

Simulations give students a chance to:

  • Practise real-world scenarios without real-world risk.

  • Learn from feedback in a supportive environment.

  • Build self-advocacy and professional communication skills.

  • Develop strategies that work for their unique needs.

This kind of tailored preparation can be the difference between just getting through a placement and truly thriving in it.

Looking ahead

This project shows that personalized simulations, grounded in student experiences and supported by interdisciplinary collaboration, can pave the way for more equitable, empowering education.

It suggests how when students are treated as co-creators, not just consumers or recipients of education, the learning becomes deeper, more inclusive and more meaningful. It also points to the relevance of broader use of co-created simulations across disciplines. Future possibilities include:

  • Adapting simulations for group settings or online delivery.

  • Partnering across departments, like theatre and business or accessibility and STEM.

  • Designing for diverse learning needs from the start, using Universal Design for Learning principles.

The approach is flexible, scalable and most importantly, human-centred. Sometimes, the best way to prepare for real life is to practise it.

The pollution court case that could reach far beyond the banks of the River Wye

Source: The Conversation – UK – By Chris Hilson, Professor of Law, Director of the Centre for Climate and Justice, University of Reading

The River Wye used to be full of wild salmon. Today it is full of algae.

And the meandering waterway which has long attracted anglers, hikers and poets is now the subject of a major pollution lawsuit.

The case – against a British water company and two chicken producers, who all deny responsibility – has been launched on behalf of almost 4,000 people who say their lives are being negatively affected by river pollution. And while legal action brought against river polluters is not new, there has never been a UK case with this many claimants.

A large range of people suing can add legitimacy to a court case, making it harder to ignore than one brought by a small group of activists.

The case is also what’s known as a “strategic” lawsuit. The claimants in the Wye litigation (which also includes the Rivers Usk and Lugg), are suing not just to secure compensation for losses they say they have suffered as a result of the pollution. They’re also trying to draw attention to the plight of some of the UK’s most cherished waterways, and attempting to secure policy change to clean them up.

Similar legal tactics have frequently – and successfully – been used by large groups in a bid to tackle climate change, where strategic litigation has been brought against companies, notably big oil firms, to help portray them as the ones responsible for damaging the climate. The Wye pollution case is similarly aimed in large part at big food companies rather than holding individual farmers responsible.

At the centre of the Wye case is “nutrient overload” of the chemicals nitrogen and phosphorus into river water from agriculture and sewage. This causes excessive growth of algae, robbing the water of oxygen and killing off fish, plants and invertebrates.

Much of the nitrogen and phosphorus is said to come from the excrement of chickens farmed close to the River Wye, and the fertiliser made from it, which is used in other types of farming.

From a global climate change perspective, chicken, as a meat product, is a greener alternative to beef and lamb because of its much lower carbon footprint (chickens produce less methane than cows and sheep).

But campaigners argue that this ignores the local environmental picture, where the concentration of the chicken industry and its nutrients in one area is a major problem. It has been claimed that around a quarter of the UK’s chickens are produced close to the Wye.

River responsibility

An important element of the River Wye court case will come down to what emissions a particular company are deemed responsible for. And again, the lawyers may look to climate change litigation for inspiration.

That’s because companies, internationally, are increasingly obliged or encouraged to report on what are known as scope 3
greenhouse gas emissions – those which result not directly from a company’s operations, but from what happens further down the line (when an oil company’s fuels are used in cars for example).

By contrast, in response to River Wye litigation, one of the defendants, chicken producer Avara Foods, has stated that its direct operations are not the ones causing the nutrient pollution.

Indeed, they argue that their farms meet some of the highest standards in the world. The problem, they say, lies elsewhere, with arable farmers nearby using poultry manure as a fertiliser for their crops.

So here we have a livestock producer apparently blaming another agricultural sector (arable), arguing that individual farmers are “responsible for how nutrients were used in their […] operations”.

Avara Foods is hence trying to limit its responsibility to only direct nutrient emissions from its operations. However, if you produce many tonnes of chicken manure and then sell it on to be used as fertiliser, some would argue – as others have argued against big oil – that you have a responsibility to reduce the effects that come later on.

On this point Avara has argued that it is “not involved in any arable operations and has no control over this activity”.

Avara has further noted that, since January 2024, it has exported all the manure from its supply chain that would previously have been locally sold as fertiliser.

But one of the claimants Justine Evans has suggested that this happened in the face of the pressure from the legal case starting, and still leaves a long period prior to that for which Avara could potentially be liable.

A spokesperson for the company told the BBC it shared concerns over the condition of the River Wye, adding: “We believe that this legal claim is based on a misunderstanding, as no manure is stored or spread on poultry-only farms that supply Avara Foods.”

They continued: “The focus instead needs to be on solutions that will improve the health of the river, addressing all forms of pollution and the effects of climate change, and for action to be taken accordingly.” Freemans of Newent Ltd, the other poultry firm being sued, is a subsidiary of Avara Foods.

Welsh Water said the company had been responsible for “significant investments over recent years”, and reached “real improvements in water quality”.

Whatever happens in the case, the urgency of dealing with these three and other polluted rivers will increase in parallel to the urgency in dealing with climate change. As the UK faces warmer weather and periods of drought, rivers will increasingly suffer from low flow levels. This in turn will exacerbate water pollution from nutrients like nitrogen and phosphorus because there is less water to dilute them.
