Globalisation has always had its critics – but until recently, they have come mainly from the left rather than the right.

In the wake of the second world war, as the world economy grew rapidly under US dominance, many on the left argued that the gains of globalisation were unequally distributed, increasing inequality in rich countries while forcing poorer countries to implement free-market policies such as opening up their financial markets, privatising their state industries and rejecting expansionary fiscal policies in favour of debt repayment – all of which mainly benefited US corporations and banks.

This was not a new concern. Back in 1841, German economist Friedrich List had argued that free trade was designed to keep Britain’s global dominance from being challenged, suggesting:

When anyone has obtained the summit of greatness, he kicks away the ladder by which he climbs up, in order to deprive others of the means of climbing up after him.

By the 1990s, critics of the US vision of a global world order such as the Nobel-winning economist Joseph Stiglitz argued that globalisation in its current form benefited the US at the expense of developing countries and workers – while author and activist Naomi Klein focused on the negative environmental and cultural consequences of the global expansion of multinational companies.

Mass left-led demonstrations broke out, disrupting global economic meetings including, most famously, the World Trade Organization (WTO) in 1999. During this “battle of Seattle”, violent exchanges between protesters and police prevented the launch of a new world trade round that had been backed by then US president, Bill Clinton. For a while, the mass mobilisation of a coalition of trade unionists, environmentalists and anti-capitalist protesters seemed set to challenge the path towards further globalisation – with anti-capitalism “Occupy” protests spreading around the world in the wake of the 2008 financial crash.

In the US, a further critique of globalisation centred on its domestic consequences for American workers – namely, job losses and lower pay – and led to calls for greater protectionism. Although initially led by trade unions and some Democratic politicians, this critique gradually gained purchase in radical right circles who opposed giving any role to international organisations like the WTO, on the grounds that they impinged on American sovereignty. According to this view, only by stopping foreign competition whose low wages undercut American workers could prosperity be restored. Immigration was another target.

Under Donald Trump’s second term as US president, these criticisms have been transformed into radical, deeply disruptive economic and social policies – with tariffs and protectionism at their heart. In so doing, Trump – despite all his grandstanding on the world stage – has confirmed what has long been clear to close observers of US politics and business: that the American century of global dominance, with the dollar as unrivalled no.1 currency, is drawing rapidly to a close.

Even before Trump first took office in 2017, the US had begun to withdraw from its leadership role in international economic institutions such as the WTO. Now, the strongest part of its economy, the hi-tech sector, is under intense pressure from China, whose economy is already bigger than the US’s by one key measure of GDP. Meanwhile, the majority of US citizens are facing stagnant incomes, higher prices and more insecure jobs.

In previous centuries, when first France and then Great Britain reached the end of their eras of world domination, these transitions had painful impacts beyond their borders. This time, with the global economy more closely integrated than ever before and no single dominant power waiting in the wings to take over, the impacts could be felt even more widely – with very damaging, if not catastrophic, results.

Why no one is ready to take the US’s place

When it comes to taking over from the US as the world’s leading hegemonic power, the only viable candidates with big enough economies are the European Union and China. But there are strong reasons to doubt that either could take on this role – notwithstanding the fact that in 2022, then US president Joe Biden’s National Security Strategy called China: “The only competitor with both the intent to reshape the international order and, increasingly, the economic, diplomatic, military and technological power to do so.”

At times Biden’s successor, President Trump, has sounded almost jealous of the control China’s leaders exert over their national economy, and the fact they do not face elections and limits on their terms in office. But a one-party, authoritarian political system which lacks legal checks and balances is a key reason China will find it hard to gain the cultural and political dominance among democratic nations that is part of achieving world no.1 status – despite the influence it already wields in large parts of Asia and Africa.

China still faces big economic challenges too. While it is already the global leader in manufactured goods (rapidly moving into hi-tech products) and the world’s largest exporter, its economy is still very unbalanced – with a much smaller consumer sector, a weak property market, many inefficient state industries that are highly indebted, and a relatively small financial sector restricted by state ownership. Nor does China possess a global currency, despite its (limited) attempts to make the renminbi a truly international currency.

As I found on a reporting trip to Shanghai in 2007 to investigate the effects of globalisation, there are also enormous differences between China’s prosperous coastal megacities – whose main thoroughfares rival New York and Paris – and the relative poverty in the interior, especially in rural areas. But nearly two decades on from that visit, with the country’s growth rate slowing, many university-educated young people are also finding it hard to find well-paid jobs now.

Meanwhile Europe – the only other contender to take the US’s place as global no.1 – is deeply politically divided, with smaller, weaker economies to the east and south far more sceptical about the benefits of globalisation, and increasingly divided on issues such as migration and the Ukraine war. The challenges of achieving broad policy agreement among all member states, and the problem of who can speak for Europe, make it unlikely that the EU as currently constituted could initiate and enforce a new global world order on its own.

The EU’s financial system also lacks the heft of the US’s. Although it has a common currency (the euro) managed by the European Central Bank, its financial system is far more fragmented. Banks are regulated nationally, and each country issues its own government bonds (although a few eurobonds now exist). This makes it hard for the euro to replace the dollar as a store of value, and reduces the incentive for foreigners to hold euros as an alternative reserve currency.

Meanwhile, any future prospects of a renewal of US global leadership look similarly unpromising. Trump’s policy of cutting taxes while increasing the size of the US government debt – which now stands at US$38 trillion, or 120% of GDP – threatens both the stability of the world economy and the ability of the US to finance this mind-boggling deficit.

Tellingly, the Trump administration shows no interest in reviving, or even engaging with, many of the international financial institutions which America once dominated, and which helped shape the world economic order – as US trade representative Jamieson Greer expressed disdainfully in the New York Times recently:

Our current, nameless global order, which is dominated by the WTO and is notionally designed to pursue economic efficiency and regulate the trade policies of its 166 member countries, is untenable and unsustainable. The US has paid for this system with the loss of industrial jobs and economic security, and the biggest winner has been China.

While the US is not, so far, withdrawing from the IMF, the Trump administration has urged it to call out China for running such a large trade surplus, while abandoning its concern about climate change. Greer concluded that the US has “subordinated our country’s economic and national security imperatives to a lowest common denominator of global consensus”.

World without a global no.1

To understand the potential dangers ahead, we must go back more than a century to the last time there was no global hegemon. By the time the first world war officially ended with the signing of the Treaty of Versailles on June 28 1919, the international economic order had collapsed. Britain, world leader over the previous century, no longer possessed the economic, political or military clout to enforce its version of globalisation.

The UK government, burdened by the huge debts it had taken out to finance the war effort, was forced to make major cuts in public spending. In 1931, it faced a sterling crisis: the pound had to be devalued as the UK exited from the gold standard for good, despite having yielded to the demands of international bankers to cut payments to the unemployed. This was a final sign that Britain had lost its dominant place in the world economic order.

The 1930s were a time of deep political unease and unrest in Britain and many other countries. In 1936, unemployed workers from Jarrow, a town in north-east England with 70% unemployment after its shipyards closed, organised a non-political “hunger march” to London which became known as the Jarrow crusade. More than 200 men, dressed in their Sunday best, marched peacefully in step for over 200 miles, gaining great support along the way. Yet when they reached London, prime minister Stanley Baldwin ignored their petition – and the men were informed their dole money would be docked because they had been unavailable for work over the past fortnight.

Europe was also facing a severe economic crisis. After Germany’s government refused to pay the reparations agreed in the 1919 Versailles treaty, saying they would bankrupt its economy, the French army occupied the German industrial heartland of the Ruhr and German workers went on strike, supported by their government. The ensuing struggle fuelled hyperinflation in Germany. By November 1923, it took 200,000 million marks to buy a loaf of bread, and the savings and pensions of the German middle class were wiped out. That month, Adolf Hitler made his first attempt to seize power in the failed “Beer hall putsch” in Munich.

In contrast, across the Atlantic, the US was enjoying a period of postwar prosperity, with a booming stock market and explosive growth of new industries such as car manufacturing. But despite emerging as the world’s strongest economic power, having financed much of the Allied war effort, it was unwilling to grasp the reins of global economic leadership.

The Republican US Congress, having blocked President Woodrow Wilson’s plan for a League of Nations, instead embraced isolationism and washed its hands of Europe’s problems. The US refused to cancel or even reduce the war debts owed it by the Allied nations, who eventually repudiated their debts. In retaliation, the US Congress banned all American banks from lending money to these so-called allies.

Then, in 1929, the affluent American “jazz age” came to an abrupt halt with a stock market crash that wiped off half its value. The country’s largest manufacturer, Ford, closed its doors for a year and laid off all its workers. With a quarter of the nation unemployed, long lines for soup kitchens were seen in every city, while those who had been evicted camped out wherever they could – including in New York’s Central Park, renamed “Hooverville” after the hapless US president of that time, Herbert Hoover.

In rural areas where the collapse in agricultural prices meant farmers could no longer make a living, armed farmers stopped food and milk trucks and destroyed their contents in a vain attempt to limit supply and raise prices. By March 1933, as President Franklin D. Roosevelt took office, the entire US banking system had ground to a standstill, with no one able to withdraw money from their bank account.

With its focus on this devastating Great Depression, the US refused to get involved in attempts at international economic cooperation. With no notice, Roosevelt withdrew from the 1933 London Conference which had been called to stabilise the world’s currencies – sending a message denouncing “the old fetishes of the so-called international bankers”.

With the US following the UK off the gold standard, the resulting currency wars exacerbated the crisis and further weakened European economies. As countries reverted to mercantilist policies of protectionism and trade wars, world trade shrank dramatically.

The situation became even worse in central Europe, where the collapse of the huge Credit-Anstalt bank in Austria in 1931 reverberated around the region. In Germany, as mass unemployment soared, centrist parties were squeezed and armed riots broke out between communist and fascist supporters. When the Nazis came to power, they introduced a policy of autarky, cutting economic ties with the west to build up their military machine.

The economic rivalries and antagonisms which weakened western economies paved the way for the rise of fascism in Germany. In some sense, Hitler – an admirer of the British empire – aspired to be the next hegemonic economic as well as military power, creating his own empire by conquering and ruthlessly exploiting the resources of the rest of Europe.

Nearly a century later, there are some disturbing parallels with that interwar period. Like America after the first world war, Trump insists that countries the US has supported militarily now owe it money for this protection. He wants to encourage currency wars by devaluing the dollar, and raise protectionist barriers to protect domestic industry. The 1920s was also a time when the US sharply limited immigration on eugenic grounds, only allowing it from northern European countries which (the eugenicists argued) would not “pollute the white race”.

Clearly, Trump does not view the lack of international cooperation that could amplify the damaging economic effects of a stock or bond market crash as a problem that should concern him. And in today’s unstable world, for all the US’s past failings as a global leader, that is a very worrying proposition.

How the US responded to the last financial crisis

Once again, the rules of the international order are breaking down. While it is possible that Trump’s approach will not be fully adopted by his successor in the White House, the direction of travel in the US will almost certainly remain sceptical about the benefits of globalisation, with limited support for any worldwide economic rules or initiatives.

We see similar scepticism about the benefits of globalisation emerging in other countries, amid the rise of rightwing populist parties in much of Europe and South America – many backed by Trump. Fuelling these parties’ support are growing concerns about income inequality, slow growth and immigration which are not being addressed by the current political system – and all of which would be exacerbated by the onset of a new global economic crisis.

With the global economy and financial system far bigger than ever before, a new crisis could be even more severe than the one that occurred in 2008, when the failure of the banking system left the world teetering on the brink of collapse.

The scale of this crisis was unprecedented, but key US and UK government officials moved boldly and swiftly. As a BBC reporter in Washington, I attended the House of Representatives’ Financial Services Committee hearing three days after Lehman Brothers went bankrupt, paralysing the global financial system, to find out the administration’s response. I remember the stunned look on the face of the committee’s chairman, Barney Frank, when he asked US Treasury secretary Hank Paulson and US Federal Reserve chairman Ben Bernanke how much money they might need to stabilise the situation:

“Let’s start with US$1 trillion,” Bernanke replied coolly. “But we have another US$2 trillion on our balance sheet if we need it.”

Shortly afterwards, the US Congress approved a US$700 billion rescue package. While the global economy has still not fully recovered from this crisis, it could have been far worse – possibly as bad as the 1930s – without such intervention.

Around the world, governments ended up pledging US$11 trillion to guarantee the solvency of their banking systems, with the UK government putting up a sum equivalent to the country’s entire yearly GDP. But it was not just governments. At the G20 summit in London in April 2009, a new US$1.1 trillion fund was set up by the International Monetary Fund (IMF) to advance money to countries that were getting into financial difficulty.

The G20 also agreed to impose tougher regulatory standards for banks and other financial institutions that would apply globally, to replace the weak regulation of banks that had been one of the main causes of the crisis. As a reporter at this summit, I recall widespread excitement and optimism that the world was finally working together to tackle its global problems, with the host prime minister, Gordon Brown, briefly glowing in the limelight as organiser of that summit.

Behind the scenes, the US Federal Reserve had also been working to contain the crisis by quietly passing on to the world’s other leading central banks nearly US$600 billion in “currency swaps” to ensure they had the dollars they needed to bail out their own banking systems. The Bank of England secretly lent UK banks £100 billion to ensure they didn’t collapse, although two of the four major banks, Royal Bank of Scotland (now NatWest) and Lloyds, ultimately had to be nationalised (to different extents) to keep the financial system stable.

However, these rescue packages for banks, while much needed to stabilise the global economy, did not extend to many of the victims of the crash – such as the 12 million US households whose homes were now worth less than the mortgage they had taken out to pay for them, or the 40% of households who experienced financial distress during the 18 months after the crash. And the ramifications of the crisis were even greater for those living in developing countries.

A few months after the 2008 financial crisis began, I travelled to Zambia, an African country totally dependent on copper exports for its foreign exchange. I visited the Luanshya copper mine near Ndola in the country’s copper belt. With demand for copper (used mainly in construction and car manufacturing) collapsing, all the copper mines had closed. Their workers, in one of the few well-paid jobs in Zambia, were forced to leave their comfortable company homes and return to sharing with their relatives in Lusaka without pay.

Zambia’s government was forced to shut down its planned poverty reduction plan, which was to be funded by mining profits. The collapse in exports also damaged the Zambian currency, which dropped sharply. This hit the country’s poorest people hard as it raised the price of food, most of which was imported.

I also visited a flower farm near Lusaka, where Dutch expats Angelique and Watze Elsinga had been growing roses for export for over a decade – employing more than 200 workers who were given housing and education. As the market for Valentine’s Day roses collapsed, their bankers, Barclays South Africa, suddenly ordered them to immediately repay all their loans, forcing them to sell their farm and dismiss their workers. Ultimately, it took a US$3.9 billion loan from the IMF and World Bank to stabilise Zambia’s economy.

Should another global financial crisis hit, it is hard to see the Trump administration (and others that follow) being as sympathetic to the plight of developing countries, or allowing the Federal Reserve to lend major sums to foreign central banks – unless it is a country politically aligned with Trump, such as Argentina. Least likely of all is the idea of Trump working with other countries to develop a global trillion-dollar rescue package to help save the world economy.

Rather, there is a real worry that reckless actions by the Trump administration – and weak global regulation of financial markets – could trigger the next global financial crisis.

What happens if the US bond market collapses?

Economic historians agree that financial crises are endemic in the history of global capitalism, and they have been increasing in frequency since the “hyper-globalisation” of the 1970s. From Latin America’s debt crisis in the 1980s to the Asia currency crisis in the late 1990s and the US dotcom stock market collapse in the early 2000s, crises have regularly devastated economies and regions around the world.

Today, the greatest risk is the collapse of the US Treasury bond market, which underpins the global financial system and is involved in 70% of global financial transactions by banks and other financial institutions. Around the world, these institutions have long regarded the US bond market, worth over $30 trillion, as a safe haven, because these “debt securities” are backed by the US central bank, the Federal Reserve.

Increasingly, the unregulated “shadow banking system” – a sector now larger than regulated global banks – is deeply involved in the bond market. Non-bank financial institutions such as private equity, hedge funds, venture capital and pension funds are largely unregulated and, unlike banks, are not required to hold reserves.

Bond market jitters are already unnerving global financial markets, which fear its unravelling could precipitate a banking crisis on the scale of 2008 – with highly leveraged transactions by these non-bank financial institutions leaving them exposed.

US bonds play a key role in maintaining the stability of the global economy. Video: Wall Street Journal.

Buyers of US bonds are also troubled by the Trump administration’s plan to raise the US deficit even higher to pay for tax cuts – with the national debt now forecast to rise to 134% of US GDP by 2035, up from 120% in 2025. Should this lead to a widespread refusal to buy more US bonds among jittery investors, their value would collapse and interest rates – both in the US and globally – would soar.

The governor of the Bank of England, Andrew Bailey, recently warned that the situation has “worrying echoes of the 2008 financial crisis”, while the head of the IMF, Kristalina Georgieva, said her worries about the collapse of private credit markets sometimes keep her awake at night.

A bad situation would grow even worse if problems in the bond market precipitate a sharp decline in the value of the dollar. The world’s “anchor currency” would no longer be seen as a safe store of value – leading to more withdrawals of funds from the US Treasury bond market, where many foreign governments hold their reserves.

A weaker dollar would also hit US exporters and multinational companies by making their goods more expensive. Yet extraordinarily, this is precisely the course advocated by Stephen Miran, chair of the US president’s Council of Economic Advisors – who Trump appears to want to be the next head of the Federal Reserve.

One example of what could happen if bond markets become destabilised occurred when the shortest-lived prime minister in UK history, Liz Truss, announced huge unfunded tax cuts in her 2022 budget, causing the value of UK gilts (the equivalent of US Treasury bonds) to plummet as interest rates spiked. Within days, the Bank of England was forced to put up an emergency £60 billion rescue fund to avoid major UK pension funds collapsing.

In the case of a US bond market crash, however, there are growing fears that the US government would be unable – and unwilling – to step in to mitigate such damage.

A new era of financial chaos

Just as worrying would be a crash of the US stock market – which, by historic standards, is currently vastly overvalued.

Huge recent increases in the US stock market’s overall value have been driven almost entirely by the “magnificent seven” hi-tech companies, which alone make up a third of its total value. If their big bet on artificial intelligence is not as lucrative as they claim, or is overshadowed by the success of China’s AI systems, a sharp downturn, similar to the dotcom crash of 2000-02, could well occur.

Jamie Dimon, head of the US’s biggest bank JPMorgan Chase, has said he is “far more worried than other [experts]” about a serious market correction, which he warned could come in the next six months to two years.

Big tech executives have been overoptimistic before. Reporting from Silicon Valley in 2001 as the dotcom bubble was bursting, I was struck by the unshakeable belief of internet startup CEOs that their share prices could only go up.

Furthermore, their companies’ high stock valuations had allowed them to take over their competitors, thus limiting competition – just as companies such as Google and Meta (Facebook) have since used their highly valued shares to purchase key assets and potential rivals including YouTube, WhatsApp, Instagram and DeepMind. History suggests this is always bad for the economy in the long run.

With the business and financial worlds now ever more closely linked, not only has the frequency of financial crises increased in the last half-century, each crisis has become more interconnected. The 2008 global financial crisis showed how dangerous this can be: a global banking crisis triggered stock market falls, collapses in the value of weak currencies, a debt crisis in developing countries – and ultimately, a global recession that has taken years to recover from.

The IMF’s latest financial stability report summarised the situation in worrying terms, highlighting “elevated” stability risks as a result of “stretched asset valuations, growing pressure in sovereign bond markets, and the increasing role of non-bank financial institutions. Despite its deep liquidity, the global foreign exchange market remains vulnerable to macrofinancial uncertainty.”

The IMF has warned about instability in the global financial system. Video: CGTN America.

I believe we may be entering a new era of sustained financial chaos during which the seeds sown by the death of globalisation – and Trump’s response to it – finally shatter the world economic and political order established after the second world war.

Trump’s high and erratically applied tariffs – aimed most strongly at China – have already made it difficult to reconfigure global supply chains. Even more worrying could be the struggle over the control of key strategic raw materials like the rare earth minerals needed for hi-tech industries, with China banning their export and the US threatening 100% tariffs in return (as well as hoping to take over Greenland, with its as-yet-untapped supply of some of these minerals).

This conflict over rare earths, vital for the computer chips needed for AI, could also threaten the market value of high-flying tech stocks such as Nvidia, the first company to exceed US$4 trillion in value.

The battle for control of critical raw materials could escalate. There is a danger that in some cases, trade wars might become real wars – just as they did in the former era of mercantilism. Many recent and current regional conflicts, from the first Iraq war aimed at the conquest of the oilfields of Kuwait, to the civil war in Sudan over control of the country’s goldmines, are rooted in economic conflicts.

The history of globalisation over the past four centuries suggests that the presence of a global superpower – for all its negative sides – has brought a degree of economic stability in an uncertain world.

In contrast, a key lesson of history is that a return to policies of mercantilism – with countries struggling to seize key natural resources for themselves and deny them to their rivals – is most likely a recipe for perpetual conflict. But this time around, in a world full of 10,000 nuclear weapons, miscalculations could be fatal if trust and certainty are undermined.

The challenges ahead are immense – and the weakness of international institutions, the limited visions of most governments and the alienation of many of their citizens are not optimistic signs.

Hurricane Melissa is a warning – why violent storms are increasingly catching the world off guard

Source: The Conversation – UK – By Alexander Baker, Research Scientist, National Centre for Atmospheric Science, University of Reading

Hurricane Melissa is tearing through the Caribbean, bringing record-breaking wind and torrential rain to Jamaica – the island’s first ever category 5 landfall. What makes Melissa so alarming isn’t just its size and strength, but the speed with which it became so powerful. In a single day, it exploded from a moderate storm into a major hurricane with 170mph winds.

Scientists call this “rapid intensification”. As the planet warms, this violent strengthening is becoming more common. These storms are especially dangerous as they often catch people off guard. That’s because forecasting rapid intensification, although improving, remains a huge challenge.

Better forecasting will depend on more detailed monitoring of a hurricane’s inner core – especially close to the eyewall, where the strongest winds occur – and on higher-resolution computer models that can better capture a storm’s complex structure. New machine learning (AI) techniques may help but are largely untested.

As things stand, rapidly intensifying storms mean that communities are often provided little warning to evacuate, and government agencies may have little time to make preparations, such as opening evacuation shelters or preparing critical infrastructure.

That’s what happened with Hurricane Otis in Mexico in 2023 and Typhoon Rai in the Philippines in 2021. Both rapidly intensified shortly before landfall, and hundreds of people died because they were unable to reach safety.

Fortunately, the chance of Melissa reaching a category 5 hurricane was forecast sometime before it made landfall, helped by the storm moving very slowly towards Jamaica.

How hurricanes will change as the Earth warms


Perfect storms

A particular set of conditions are required to fuel rapid intensification: high humidity in the atmosphere, low wind shear (the change in wind speed with height), and warm sea-surface temperatures. Recent research suggests that since the early 1980s, warmer seas and a more moist atmosphere means these conditions are becoming more common. These trends can’t be explained by natural variability. It seems human-caused climate change is significantly increasing the probability of rapid intensification.

In the case of Melissa, the fingerprints of climate change are visible on many of the factors that made it such a devastating storm. Sea-surface temperatures in the region are currently more than a degree above normal – conditions that may be 500 to 800 times more likely due to climate change. Warmer seas provide extra energy for a storm’s intensification. Rising sea levels also mean storm surges and coastal flooding are more severe.

Scientists are confident that rainfall is increasing as a result of climate change, because a warmer atmosphere holds more moisture, a trend evident in the North Atlantic. Melissa is travelling slowly, which leads to higher rainfall totals over land. Forecasts predicted mountainous regions of Jamaica could receive up to a metre of rainfall, raising the risk of severe flooding and landslides.

Some studies even suggest climate change is slowing down the speed of cyclones themselves (the rate at which the whole storm moves). This would mean they linger over land and dump more rain. Simulations by a colleague of ours at the University of Reading confirmed that past hurricanes striking Jamaica would produce more rainfall in today’s warmer climate.

The growing tendency for storms to rapidly intensify is helping more of them to reach the strongest categories, and that can be deadly when this surge in strength is not well forecasted. As the planet warms, this risk will only grow. That makes it crucial for scientists to improve hurricane monitoring and forecast models, as well as for emergency responders to prepare for the scenario of an intense hurricane arriving with little time to prepare.

Hurricane Melissa has brought the risks into sharp focus: storms are intensifying faster, hitting harder and giving people less time to escape.

Bugonia: why some people’s brains cling to the idea that aliens are real

Source: The Conversation – UK – By Dan Baumgardt, Senior Lecturer, School of Psychology and Neuroscience, University of Bristol

The latest absurdist offering from Yorgos Lanthimos, director of The Favourite and Poor Things, hits cinemas this week, and Bugonia promises to be another strange and rollicking masterpiece of complete, unmissable chaos.

Lanthimos’s muse Emma Stone and Jesse Plemons reunite in this darkly comic tale about a pharmaceutical CEO (Stone) kidnapped by conspiracy theorists. Believing she is an extraterrestrial intent on destroying Earth, they imprison her in an effort to save humanity.

If brain transplants like the one in Poor Things were possible, this is how they might work


The film is a remake of Save the Green Planet!, the 2003 South Korean cult classic. Beneath its surreal surface lies a fascinating question: why do some people genuinely believe in aliens – not as fiction, but as fact?

In psychiatry, a delusion is defined as a fixed, false belief. It is false because it is factually incorrect, and fixed because it is unshakeable and resists all evidence to the contrary. However irrational it appears to others, it feels entirely true to the person experiencing it.

Delusions often coexist with hallucinations, in which people see figures, hear voices or sense a presence that is not really there.

In the modern era, alien delusions take many forms. Some believe their bodies are controlled by extraterrestrials or that aliens are manipulating their thoughts. Others develop persecutory beliefs, convinced that aliens are trying to harm them or have implanted tracking devices in their bodies.

Some even experience identity delusions, believing they are aliens themselves or have been chosen for a special mission. Grandiose delusions involve exaggerated beliefs in one’s status, importance or power.

Such symptoms are most often seen in psychotic disorders including schizophrenia, though they can also occur in bipolar disorder or as a result of substance misuse, particularly stimulants or hallucinogens such as cocaine, amphetamines or LSD.

A brief history of alien beliefs

Today, alien delusions draw on decades of popular culture, from The X-Files and Prometheus to District 9 and ET. But what about the times before flying saucers and abduction stories filled our screens?

As far back as the middle ages, people described experiences that might now be considered delusional. Religious belief dominated, so visions of angels and devils provided the language of control and persecution. During the witchcraft panics, people claimed to be tormented or possessed by witches and demons.

As science and technology advanced, so did the content of delusions. In the early 20th century, writers such as HG Wells helped popularise the idea of intelligent life beyond Earth through works like The War of the Worlds, a story about a Martian invasion that captured both public imagination and anxiety about the unknown.

With the rise of radio, psychiatrists began recording delusions involving radio waves, in which patients believed their thoughts were being transmitted or received through the air. As technology evolved, so did the fears: people began reporting delusions of technical or alien control, convinced that X-rays, lasers or even the internet were influencing their minds.

In July 1947, debris recovered from a ranch near Roswell, New Mexico, was initially claimed to be from a “flying disc” before being reidentified by the US military as a weather balloon. The contradictory reports ignited decades of speculation about government cover-ups and alien visitation, embedding UFO imagery deep in the popular imagination. After this post-war Roswell incident, UFOs became a cultural fixture – and soon, a clinical one.

Psychiatrists soon encountered patients whose delusions mirrored these stories of flying saucers and alien abductions. Over time, such beliefs evolved alongside new technologies and social anxieties, from government surveillance to nanotechnology and artificial intelligence. The motifs, however, remain strikingly consistent: possession, control, abduction. The vocabulary changes, but the psychology endures.

Part of the “normal” brain?

While delusions are fixed and distressing, other alien experiences are not necessarily pathological. Many people report seeing unexplained lights, shapes or figures, often during the hazy transitions between wakefulness and sleep. Others interpret these sensations within cultural, religious or recreational contexts as forms of cosmic contact. Such fleeting experiences are surprisingly common and usually harmless.

So why does the mind reach for alien imagery when constructing delusions? The brain may simply use the symbols at hand – stories, myths, films – to make sense of fear or confusion. In that way, delusion is not so much nonsense as meaning-making gone astray.

This brings us back to Bugonia.

The film’s title comes from the Greek word bougonia, meaning “ox birth”. It refers to an ancient Mediterranean myth in which dead animals were believed to give rise to swarms of bees – a metaphor for how life, or meaning, can emerge from decay.

Lanthimos takes that idea both literally and symbolically. In Bugonia, delusion and revelation, horror and comedy, all blur into one. Stone and Plemons deliver outstanding performances, with Stone in particular chasing a deserved third Oscar.

Beyond its absurdity, Bugonia leaves a quietly unsettling thought: that the distance between imagination and “madness” is far thinner than we’d like to believe – and that perhaps every delusion begins as the mind’s attempt to create order from chaos.

China’s new controls on rare earths create challenges for the west’s plans for green tech

Source: The Conversation – UK – By Chee Meng Tan, Assistant Professor of Business Economics, University of Nottingham

China recently announced that it was putting new controls on the export of rare earth elements, sparking a new round in the country’s ongoing trade war with the US.

Donald Trump responded by threatening to ramp up tariffs on Chinese goods by a further 100%. This will all be under discussion when China’s president Xi Jinping and Trump meet on October 30 at the Asia Pacific Economic Conference in South Korea.

China has built an effective monopoly over rare earth metals, the 17 metallic elements that are not actually rare but are very difficult to mine and process. Most electric vehicles (EVs), smartphones or solar panels depend on these rare earths.

China mines 70% and refines 92% of these increasingly important metals, and manufactures 98% of the world’s rare earth magnets used in EVs, electronics, medical devices and other clean tech. In recent years, these essential minerals have become a crucial part of China’s economic agenda as it tries to focus on “high quality development” in advanced and green technology

The recent announcement from Beijing has raised concerns about global access to these essential minerals. If the supply of rare earths available to the outside world diminishes, the cost of manufacturing green tech would rise and drive up prices worldwide. If there is anything that would stall the development of the green economy, this could be it.

In response to the announcement, Trump initially suggested he might cancel an upcoming meeting with Chinese president Xi. However, the meeting now looks set to go ahead, and access to rare earths is likely to be high on the agenda.

The battle to gain access to rare earth minerals is important to developing more green tech.

Trump had also announced that he was considering a ban on exports to China of all products made with US software such as laptops and jet engines, and industrial equipment. This might reduce Beijing’s ability to design essential components for AI chips, hampering its bid for dominance in clean tech.

Prior to Trump’s latest threats, electric vehicles coming from China had already been hit by a 100% US tariff, while import duties for solar cells and lithium batteries stood at 50% and 25% respectively.

But the result might have surprised Trump. As US-made goods are exempt from tariffs from paying tariffs, Chinese firms have set up production sites in the US to circumvent Trump’s tariffs. Instead of helping domestic US companies, Trump’s policies have done the opposite.

For instance, the solar manufacturing capacity of Chinese firms based in the US has grown so large that it now accounts for 39% of all solar panel energy output in the country versus only 24% from US firms.

But even if Chinese clean tech sales in US were severely affected by the tariffs, most of China’s green tech is heading elsewhere.

Based on my estimations using data from the energy thinktank Ember, Chinese green tech exports globally in 2024 were valued at US$184.06 billion (£139 billion), while total exports to the US stood at US$20.66 billion. The US market accounted for only 11.2% of the total proportion of total Chinese green tech exports, while that number from January to September 2025 has dipped to 7.8%.

Compared to the EU (29.95%) and Asian market (27.97%) in 2024, the US market appears relatively small. So higher tariffs would harm China’s economy, but the damage may not be as substantial as Trump might imagine. However, the EU’s plans to meet climate targets is massively dependent on these Chinese exports.

Problems for Beijing?

The US has already put restrictions on which technologies China can buy from the US. China can still manufacture electric vehicles, solar panels and wind turbines without US software. But without the most advanced technologies from the US, Chinese firms will have fewer options.

While there are indications that the tech gap between Washington and Beijing may be shrinking, the US still possesses some of the most advanced technologies that are crucial for green tech development. These include advanced semiconductors, which are needed to make AI chips.

Such components and machinery are essential to China’s claim to green leadership since they allow users to automate EVs, solar panels and wind turbines, while ensuring their efficiency and optimising energy use. Simply put, without the best semiconductors and the AI chips, China won’t be able to create world-leading clean tech.

China may have metals but without US chips and software, it’s green economic momentum might stall – at least until China’s semiconductor and AI tech catches up with the US. Chinese economic progress and its green leadership may be dependent on gaining better trade deals, even if it does still have a massive advantage.

Could tactical voting could block Reform in future elections? Lessons from the Caerphilly byelection

Source: The Conversation – UK – By Thomas Lockwood, PhD Researcher in Politics, York St John University

Plaid Cymru’s overwhelming victory in the recent Caerphilly Senedd byelection shattered over a century of political tradition. Lindsay Whittle took the seat with 15,691 votes. Labour, which had held the seat since it was created, came away with just 3,713 votes.

Reform came second to Plaid, with 12,113 votes. And while this was an impressive performance, the fact that it failed to win Caerphilly even after vast amounts of time and money spent on the campaign has led to speculation that tactical voting played a part in this byelection.

A big clue that tactical voting was at work in Caerphilly was the recorded turnout. Typically, byelections in Wales have been low-key affairs. Turnouts are low and incumbents generally win. The national average for a Senedd vote in a constituency has never tipped over 50%. In Caerphilly, turnout climbed from 44% in the 2021 election to 50.4% in this byelection.

And while local voters clearly backed Plaid Cymru for plenty of reasons, the extremely low vote count for other parties does suggest at least some lent their vote to Plaid to keep out Reform. The Conservative vote collapsed to fewer than 700 votes and the Lib Dems and Greens, so often the recipients of tactical votes themselves, each took just 1.5% of the votes in Caerphilly.

Anecdotes from the vote count support this. The BBC recounted “extraordinary stories” of habitual supporters of the Conservatives, a pro-union party, voting Plaid to block Reform.

The increased turnout and Plaid’s 27.4% swing both suggest a mobilisation, triggered by polling and a wider national narrative which persuasively contends that Reform is ahead of other parties. Does the result therefore imply that Reform can be beaten elsewhere if voters take the right approach to tactical voting?

How England’s new Reform councillors compare in their views to other parties


The limits of Reform’s surge

Reform entered the Caerphilly race with no prior foothold in the constituency. The party mobilised heavily and, it had seemed, effectively. Nigel Farage and other senior Reform figures made multiple visits to the area to campaign for their candidate, Llŷr Powell. Pre-election polls, including one by Survation which had Reform leading Plaid by 42% to 38%, raised expectations of a breakthrough.

And it is true that Reform’s ultimate 36% vote share reflects its growing appeal among disaffected working-class voters. It did capitalise on the same anti-establishment sentiment that has seen the party top UK-wide polls for much of the past year.

Yet, the result also exposes Reform’s vulnerabilities. As with the Hamilton, Larkhall and Stonehouse byelection for the Scottish parliament earlier in the summer, Reform failed to convert intensive campaigning into victory.

The role and reach of tactical voting

Underneath the hype, Farage is unpopular. Polls suggest as many as 60% of voters are opposed to him being prime minister. That presents an opportunity for opponents to unite behind a more broadly acceptable candidate.

In this volatile political era, where voters show little loyalty to tradition, smaller parties like Plaid Cymru, the SNP, Greens and even Pro-Gaza independents could frame themselves as the “real alternative” to Reform. Depending on local dynamics, they could attempt to draw tactical support.

It should be noted, however, that tactical voting cuts both ways. While it denied Reform a victory in Caerphilly, the party could attract tactical support from Conservative voters eager to oust Labour governments.

In England, without equivalents to Plaid or the SNP to siphon anti-establishment sentiment, Reform may consolidate its grip on working-class disillusionment. This trend was evident in Labour’s collapse in the Runcorn and Helsby Westminster byelection in May 2025, which enabled Reform to take the seat.

In Caerphilly, Labour’s vote fell amid grievances including the slow pace of change to improve living standards, policy u-turns and a fatigue with Welsh Labour, which has been in power in the Senedd since its creation in 1999.

Such grievances can be felt across the UK more broadly – with winter-fuel policy u-turns, and a general dissatisfaction with how long it is taking Labour to deliver on promises to improve living standards. Concern about immigration is also used to punish Labour in both the regular voting intention polls and at the ballot box in council byelections.

An anti-Reform majority does exist – and it has shown up in several contests, including in races Reform has ultimately won but on less than 50% of the vote. Harnessing this anti-Reform majority, however, requires a level of co-ordination rarely seen in the UK’s electoral history.

Unlike the 1997 anti-Conservative wave, there is no single opposition brand. Instead, the anti-Reform vote is split across Labour, Liberal Democrats, Greens, nationalists and independents – and, arguably, the Conservatives too.

In Caerphilly, we saw this fragmentation briefly turn into coalescence. This implies that a clear polling trigger, showing Reform ahead in a seat, can focus the minds of voters and drive tactical thinking. It also helped that these voters were offered a Plaid candidate with deep community roots and a strong, progressive message.

What is potentially harder in a general election is the presentation of a local contest as extremely high stakes in the media. Caerphilly drew unprecedented attention precisely because it was being framed as a test case for Reform in Wales, which may explain the level of anti-Reform vote.

In a multi-polar UK, the anti-Reform majority is real – but not pro-any one party by default. Importantly, it is anti-populist, anti-incumbent and regionally variable. Nearly all of the mainstream parties on the centre ground and left wing of politics are claiming to be the real alternative to Reform.

Reform’s path to power lies in building a lead that is too large for tactical voting to overcome, or in electoral systems which reward vote share over seat efficiency. This is why it remains hopeful of success in May 2026 in Wales, where the election is being held under a proportional voting system.

As the UK heads towards the 2026 devolved elections and a likely 2029-30 general election, Caerphilly offers a blueprint for resistance to Reform’s national surge. It also offers a warning for the other parties: stopping Reform is not the same as winning.

Climate change is becoming an insurance crisis

Source: The Conversation – UK – By Meilan Yan, Senior Lecturer in Financial Economics, Loughborough University

Imagine waking up to find your living room underwater for the second time in five years. You try to claim insurance, only to be told your property is now uninsurable. Premiums have tripled. Your mortgage lender is concerned. And your biggest asset, your home, is rapidly losing value.

This isn’t just a personal disaster. It’s a warning sign of a much broader crisis.

The risks associated with climate change are breaking the insurance industry. In the past decade alone, flood frequency has increased fourfold in the tropics and 2.5 times in mid-latitude regions). In the UK, at least one in six people already live with flood risk, heavy-rainfall extremes are increasing, and expected annual damages could rise by 27% by the 2050s.

Insurance claims from extreme weather are surging. The Association of British Insurers (the UK insurance and long-term savings trade body) reports a record £585 million in home weather-damage payouts for 2024.

Climate change is driving more frequent and severe events, pushing traditional insurance models to their limits. Insurers are left with little choice but to raise premiums sharply or withdraw coverage entirely. When insurance becomes unaffordable or unavailable, households are exposed, property values fall, mortgages become harder to secure, and the risk of a wider financial crisis grows.


Ever wondered how to spend or invest your money in ways that actually benefit people and planet? Or are you curious about the connection between insurance and the climate crisis?

Green Your Money is a new series from the business and environment teams at The Conversation exploring how to make money really matter. Practical and accessible insights from financial experts in the know.


Our research into the insurance industry shows that UK resilience is falling behind. Policymakers in the UK tried to avert an insurance crisis by launching Flood Re in 2016, a joint scheme between government and insurers designed to keep insurance affordable for households in high-risk areas. It was meant as a temporary bridge, due to close in 2039 once stronger flood defences and better land-use planning are in place.

But progress has been painfully slow. In January 2024, the House of Commons public accounts committee reported that the government’s £5.2 billion flood defence programme is 40% behind schedule and expected to protect just 200,000 properties by 2027 — far short of its original 336,000 target.

By 2025, Flood Re has been under mounting strain. Reinsurance costs had have risen by £100 million in just three years, and policy uptakes have jumped by 20% in a single year – both signs that private insurers were retreating from high-risk markets.

In July 2025, Flood Re’s CEO, Perry Thomas, warned that the UK’s overall flood resilience have worsened since the scheme’s launch, as mortgage lenders, housebuilders, and successive governments have “failed to pull their weight”.

Storm damage is more likely as climate change risk increases.

When insurance becomes unaffordable or unavailable, households are left exposed and property values decline, making mortgages harder to obtain. This erosion of coverage threatens the wider financial system: banks rely on insured property as collateral, but without cover, that collateral rapidly loses value.

If the government fails to meet its climate adaptation targets, as many as 3 million UK homes could become effectively worthless within 30 years.

For the banking sector, this creates the risk of homes becoming stranded assets — uninsurable, unmortgageable and falling in value — leading to rising defaults and mounting losses. Unless lenders adopt climate-adjusted risk models that integrate physical hazards such as flooding, storms and heatwaves, they risk underestimating the true exposure of their mortgage portfolios.

If these climate-risk-exposed mortgages are mispriced and then bundled into mortgage-backed securities and sold to investors, the resulting shock could cascade through credit markets – like the 2008 subprime mortgage crisis, when large volumes of high-risk home loans to borrowers with poor or limited credit histories were repackaged and sold as safe investments. The difference is that this time the crash would be driven by physical climate damage rather than purely financial mismanagement.

A one-way street

Traditional financial crises follow cycles of growth, downturn and recovery, but climate risk moves in only one direction. Rising global temperatures are driving more frequent and severe floods and storms. Without timely adaptation, the damage compounds, eroding property values, undermining insurance and threatening financial stability.

Historical insurance models treated extreme weather as rare “tail risks,” but these events are now more frequent, severe, and interconnected. The tail is becoming “fat,” and shocks ripple across sectors and regions. In short, risk is evolving and insurance frameworks must evolve with it.

Flooding is no longer just an environmental issue. It is a systemic financial threat. Insurers, regulators and lenders must adopt forward-looking models that translate physical climate risks into financial metrics. These models influence market behaviour by shaping how capital is allocated, assets are valued, and risks are priced.

This, in turn, guides investment, planning and adaptation — the process of adjusting systems, infrastructure and practices to withstand and recover from climate impacts.

Effective adaptation measures, such as upgraded flood defences, reduce the future risk of climate-related damage. It’s a feedback loop: better modelling enables smarter adaptation, which in turn strengthens financial stability.

After the first world war, séances boomed – and dead soldiers ‘wrote’ home

Source: The Conversation – UK – By Alice Vernon, Lecturer in Creative Writing and 19th-Century Literature, Aberystwyth University

A typical séance in the 1920s. The Graphic, CC BY-SA

In March 1915, a young British man named Raymond Lodge was deployed to Ypres, France, to fight on the front lines of the first world war. By September, he was dead, aged just 26.

A few weeks later, however, Raymond got in touch with his family. “TELL FATHER I HAVE MET SOME FRIENDS OF HIS”, came the message hastily scrawled in all caps by the spiritualist medium Mrs Osborne Leonard.

Raymond’s father was Sir Oliver Lodge, a prominent physicist whose work helped to develop radio communications. Sir Oliver was also a member of the Society for Psychical Research, an organisation which, among other things, investigated ghosts. The “friends” Raymond had apparently met beyond the grave included F.W.H. Myers, a founding member of the society, who had died in 1901.

Sir Oliver, previously fairly sceptical, was soon drawn into lengthy séances with Mrs Leonard, poring over messages allegedly from Raymond about death and the afterlife. He compiled them into a book entitled Raymond, or Life and Death, which was published in 1916. It proved so popular that it ran to many editions, with soldiers on the front being sent copies by their loved ones.

Spiritualism began in the late 1840s as a pseudo-Christian practice that believed communication with the dead was entirely possible. While it dwindled in popularity at the turn of the century, it was reinvigorated to new levels in the aftermath of the first world war. The popularity of Lodge’s book, moreover, led to dozens of copycat publications, where other soldiers “wrote” of their experiences of the utopian spiritualist afterlife to their families.

Claude’s Book (1919) is one such example, “transcribed” from séances with young Claude by his mother, L. Kelway-Bamber. Kelway-Bamber, having been so heartened by Sir Oliver’s sittings, had hired Mrs Leonard herself to get in touch with her son. Spiritualist mediums were in high demand once more.

Beyond the cynicism

It’s easy to dismiss these séances, even to scoff at them as nothing more than charlatans exploiting public grief, especially from the point of view of modern scepticism. When I was researching my new book, Ghosted: A History of Ghost Hunting and Why We Keep Looking, this was my initial reaction to reading about these bizarre encounters with the spirits of the dead.

But as a sociological phenomenon, borne of mass grief, I think it’s more complicated than that. We may laugh at fraudulent mediums quivering melodramatically as they channel the so-called spirits of the dead, but to discuss spiritualism’s cultural significance requires a more nuanced and sensitive approach.

By the end of the first world war, nearly 9 million soldiers had been killed. General mortality rates were already high prior to the war, and people were no strangers to sudden, unexpected bereavement. But never before had death affected so many people at once, and taken so many young men in the prime of their life.

If we look at spiritualism in the aftermath of the first world war, not to identify fraud and shun its believers as being gullible, we can build up an incredibly detailed picture of why so many clung to séance tables in the hope of contacting their loved ones again.

Everyone’s loss of their son, brother or husband was uniquely painful, and yet these deaths lost their significance when half the families on the street had also lost their young men. Yet, suddenly, everyone knew Raymond Lodge’s name. He stood out among the legions of dead Tommies, because of the séances Sir Oliver held with Mrs Leonard.

This, I think, is why so many grieving families took up spiritualism and wrote their own books – not to piggyback on Raymond’s popularity, but to make their sons, brothers and husbands seem special, too. Moreover, many didn’t know exactly what had happened to soldiers; being able to “speak” to them from beyond the grave made it seem like they were happy and at peace, enjoying themselves in the afterlife, and not in pieces in a muddy ditch thousands of miles from home.

Mary Lodge, Raymond’s mother, sums up the problem with a brief sentence her husband includes in the book: “We can face Christmas now.” We can accuse Mrs Leonard of exploiting grief, but we can’t deny that it eased the suffering of many, regardless of the ethical and moral dilemmas posed by spiritualism.

The history of ghost-hunting and séances is rife with fraud, and scepticism is often required to read around anecdotes to uncover what was really happening, but it’s also a vital resource to help us understand grief and fear of death at certain points in human history. By examining the motivation behind ghost-hunting from a more sympathetic perspective, we can learn a great deal about what it means to be alive.

‘Hallucinated’ cases are affecting lawyers’ careers – they need to be trained to use AI

Source: The Conversation – UK – By Craig Smith, Lecturer in Law, University of Salford

Gorodenkoff/Shutterstock

Generative artificial intelligence, which produces original content by drawing on large existing datasets, has been hailed as a revolutionary tool for lawyers. From drafting contracts to summarising case law, generative AI tools such as ChatGPT and Lexis+ AI promise speed and efficiency.

But the English courts are now seeing a darker side of generative AI. This includes fabricated cases, invented quotations, and misleading citations entering court documents.

As someone who studies how technology and the law interact, I argue it is vital that lawyers are taught how, and how not, to use generative AI. Lawyers need to be able to avoid the risk of sanctions for breaking the rules, but also the development of a legal system that risks deciding questions of justice based on fabricated case law.

On 6 June 2025, the high court handed down a landmark judgment on two separate cases: Frederick Ayinde v The London Borough of Haringey and Hamad Al-Haroun v Qatar National Bank QPSC and QNB Capital LLC.

The court reprimanded a pupil barrister (a trainee) and a solicitor after their submissions contained fictitious and inaccurate case law. The judges were clear: “freely available generative artificial intelligence tools… are not capable of conducting reliable legal research”.

As such, the use of unverified AI output can no longer be excused as error or oversight. Lawyers, junior or senior, are fully responsible for what they put before the court.

Hallucinated case law

AI “hallucinations” – the confident generation of non-existent or misattributed information – are well documented. Legal cases are no exception. Research has recently found that hallucination rates range from 58% to 88% in response to specific legal queries, often on precisely the sorts of issues lawyers are asked to resolve.

These errors have now leapt off the screen and into real legal proceedings. In Ayinde, the trainee barrister cited a case that did not exist at all. The erroneous example had been misattributed to a genuine case number from a completely different matter.

In Al-Haroun, a solicitor listed 45 cases provided by his client. Of these, 18 were fictitious and many others irrelevant. The judicial assistant is quoted in the judgment as saying: “The vast majority of the authorities are made up or misunderstood”.

These incidents highlight a profession facing a perfect storm: overstretched practitioners, increasingly powerful but unreliable AI tools, and courts no longer willing to treat errors as mishaps. For the junior legal profession, the consequences are stark.

Many are experimenting with AI out of necessity or curiosity. Without the training to spot hallucinations, though, new lawyers risk reputational damage before their careers have fully begun.

The high court took a disciplinary approach, placing responsibility squarely on the individual and their supervisors. This raises a pressing question. Are junior lawyers being punished too harshly for what is, at least in part, a training and supervision gap?

Education as prevention

Law schools have long taught research methods, ethics, and citation practice. What is new is the need to frame those same skills around generative AI.

While many law schools and universities are either exploring AI within their modules or creating new modules that look at AI, there is a broader shift towards considering how AI is changing the legal sector as a whole.

Students must learn why AI produces hallucinations, how to design prompts responsibly, how to verify outputs against authoritative databases and when using such tools may be inappropriate.

The high court’s insistence on responsibility is justified. The integrity of justice depends on accurate citations and honest advocacy. But the solution cannot rest on sanction alone.

How to use AI – and how not to use it – should be part of legal training.

If AI is part of legal practice, then AI training and literacy must be part of legal training. Regulators, professional bodies and universities share a collective duty to ensure that junior lawyers are not left to learn through error or in the most unforgiving of environments, the courtroom.

Similar issues have arisen from non-legal professionals. In a Manchester civil case, a litigant in person admitted relying on ChatGPT to generate legal authorities in support of their argument. The individual returned to court with four citations, one entirely fabricated and three with genuine case names but with fictitious quotations attributed to them.

While the submissions appeared legitimate, closer inspection by opposing counsel revealed the paragraphs did not exist. The judge accepted the litigant had been inadvertently misled by the AI tool and imposed no penalty. This shows both the risks of unverified AI-generated content entering proceedings and the challenges for unrepresented parties in navigating court processes.

The message from Ayinde and Al-Haroun is simple but profound: using GenAI does not reduce a lawyer’s professional duty, it heightens it. For junior lawyers, that duty will arrive on day one. The challenge for legal educators is to prepare students for this reality, embedding AI verification, transparency, and ethical reasoning into the curriculum.

Keeping up with the Kardashians? Why owning more can leave us feeling less

Source: The Conversation – UK – By Cathrine Jansson-Boyd, Professor of Consumer Psychology, Anglia Ruskin University

The Kardashians are back with a new season of their reality series The Kardashians on Disney Plus.

As a researcher of consumer psychology, I have written about consumer neuroscience and how brands and media shape behaviour and self-perception. Watching The Kardashians through that lens reveals more than entertainment. It exposes how luxury and aspiration are woven into identity and sold back to us as self-worth.

The first episode is a materialistic feast. There are close-ups of Dior and Chanel handbags and belts, diamond jewellery and a house sign that reads: “Need money for Birkin.” The Kardashians drive luxury cars, wear designer sunglasses indoors and chat about their Saint Laurent outfits.

Even the camera lingers on the glittering shop windows of Rodeo Drive in Beverly Hills, home to some of the world’s most exclusive designer stores, though no one is actually shopping. If you haven’t seen it, you probably get the idea. In the Kardashian universe, the unspoken motto seems to be: “To have is to be.”

In their world, material possessions are woven into identity and presented as something to aspire to. But is it really all that glamorous?

Overconsumption can lower our wellbeing. Young people, in particular, often turn to excessive consumption to fit in, boost confidence or gain prestige. Teenagers who idolise others for their wealth or possessions are more likely to struggle with their sense of identity later in life.

Research shows that children and adolescents who place strong importance on material possessions often struggle to develop a clear sense of identity. Without learning who they are beyond what they own, they may find it harder to build lasting self-worth and life satisfaction.

Rather than helping us define who we are, possessions can get in the way. They can obscure or distort our sense of self, leading us to equate value with visibility. On top of that, materialism is linked to depression, likely because people often fail to achieve the identity and happiness they hope consumption will bring.

The Kardashian-Jenners have a massive following. Sisters Kylie, Kim and Khloé each have more than 300 million Instagram followers, a clear sign of their influence.

When we admire someone, we naturally compare ourselves to them, a process known as social comparison. It helps us judge where we stand, whether we are better or worse off than others. In this context, owning the same bag, car or outfit becomes a way to measure worth, since possessions often symbolise status and make the buyer feel closer to the celebrity, as if buying into their world.

Social comparison is known to drive materialism. It can start to feel like a competition to “catch up” with those we look up to through conspicuous consumption.

When we fail to keep up with the Kardashians, we may feel inadequate, even if we know deep down we were never in the same race. The Kardashian brand cleverly capitalises on this very idea.

The original series title, Keeping Up With the Kardashians, puns on the human instinct to compare and compete. This dynamic fuels not only the show’s popularity but also its beauty, fashion and lifestyle empires, which invite fans to buy into the brand both literally and symbolically.

You might think the solution is simply to choose better role models, but it is not that straightforward. People often compare themselves to others without realising it, automatically relying on social comparison when processing information about other people. This tendency does not stop at television.

Social media platforms intensify the same dynamic, giving us endless opportunities to measure our worth against curated snapshots of other people’s lives. Research from 2024 shows that heavy exposure to idealised social-media content is associated with increased materialism, lower life satisfaction and greater stress.

Another study found that engagement with influencer content featuring luxury goods can trigger upward social comparison – the tendency to compare ourselves with people we see as better off – leading to feelings of envy and a stronger urge to buy similar products in order to close that gap.

From influencer “unboxings,” where people film themselves opening luxury purchases, to filtered “day in the life” videos, social media users are constantly exposed to lifestyles that appear effortlessly perfect. When we scroll through feeds full of luxury, beauty and success, we can become more materialistic without ever consciously deciding to.

Seeing the extreme wealth of people like the Kardashians surrounded by luxury can spark feelings of envy and relative deprivation, leading to dissatisfaction with our own lives. That dissatisfaction can then trigger compulsive shopping as we try to soothe those uncomfortable emotions and project wealth ourselves.

Unsurprisingly, compulsive buying is closely tied to materialism. If you value possessions and feel envy toward others, you are far more likely to buy impulsively in an attempt to catch up.

Watching glamorous lifestyles where people seem to have it all can be fun escapism, but it also blurs the line between aspiration and insecurity. Shows like The Kardashians offer a fantasy of perfection that few can match, yet they invite us to measure ourselves against it.

In the end, the pursuit of luxury may leave us feeling emptier, not richer. After all, when having becomes being, it is worth asking what is left of the self once the shopping stops.

How the first animals evolved – a new clue from a tiny relative

Source: The Conversation – UK – By Max Telford, Jodrell Professor of Zoology and Comparative Anatomy, UCL

The next time you go wild swimming, whether in a lake, river or sea, you are probably sharing the water with one of your tiniest, yet closest relatives.

This near-family member is a microscopic, single-celled organism called a choanoflagellate. Scientists are still puzzled by how animals evolved from such simple beginnings. But a new paper describes the discovery of an important new clue.

Choanoflagellates, like most single celled organisms can only survive in water where they live much of their life as a single cell, no more complex than an amoeba.

They are nevertheless more closely related to our own kingdom of life than any other kind of organism is – choanoflagellates are cousins of the animals. Engraved in the structure and function of choanoflagellate cells and written in their DNA code, scientists are finding evidence showing how the very first animals evolved.

Before we get to the new clue, it is worth thinking about what makes animals unique. As I describe in my new book, the simple answer is that, compared to most of the rest of life, animals have large and complicated bodies built from many cells. Your own body contains tens of trillions of cells and even a tiny fruit fly has close to a million.

Our oldest animal ancestor must have evolved a way for its many cells to stick together and form a super-organism from a host of cooperating cells.

The first animals must also have invented ways to produce the many different kinds of cells we have today; muscle cells, nerve cells, egg cells and sperm to name a few. The division of labour among different kinds of cells is one aspect of arguably the biggest invention of the first animals which is embryogenesis.

This is the earliest period of an animal’s life when, starting from a single fertilised egg cell, cell division begins to create all the cells that will make up the animal. These cells then each take on their own specific task and finally the many cells get carefully organised to make a functioning organism.

Scientists are hoping that studying choanoflagellates will help them learn how these skills first evolved.

Choanoflagellates don’t have large, complex bodies and they don’t have embryogenesis. They do, however, have a few animal like qualities. Their cells, for example, can adopt a handful of different shapes with different roles.

Just as our cells can take the form of a nerve or a muscle, theirs can switch from the standard funnel and flagellum form to become amorphous, shape-shifting blobs like an amoeba.

Choanoflagellates can also make tiny multi-celled colonies. In the presence of certain species of bacteria their cells stick together to make little groups of cells called rosettes. The rosettes seem to form because they are better at catching the bacteria (which the choanoflagellates eat) than single cells are.

The rosettes can grow a little, but when they reach a size of about ten cells the bonds between the cells stretch and snap, splitting the rosettes down the middle to form two smaller rosettes of cooperating choanoflagellates.

The resemblance of these rosettes to the earliest stages of an animal embryo seems like a coincidence, however. Unlike an animal embryo, they are not destined to develop into anything else. The new study is about the growth of these rosettes.

In many animals, from mice to flies, there is small group of genes that work together to control how big different organs get – how many cells they contain. Named Hippo, Warts and Yorkie, these genes sound like a mob of gangsters.

They are known collectively as the Hippo pathway. When genes in the Hippo pathway mutate in a growing fly or mouse embryo, the result is flies with huge eyes or newborn mice with monstrous livers.

In adult humans, when Hippo genes mutate, they can produce cancerous growths of uncontrollably dividing cells.

Choanoflagellates have a host of genes in common with animals. Although they don’t have organs like eyes or livers (or embryos or cancer), they do have the genes of the Hippo gang. The new paper first describes how the researchers developed a new technique that lets scientists target any gene in a choanoflagellate so that it can be deliberately mutated.

When the Warts gene was mutated, the rosettes of cells grew twice as large so that they ended up containing 20 cells or more. This uncontrolled growth is strikingly similar to what had been seen in previous studies of flies, mice and some human cancers.

The details of just how the Hippo genes control rosette size are not yet know. But the new work adds to the picture we are building of the single celled precursor of the animals. It is another animal-like characteristic of the choanoflagellates.

If we travelled back in time to meet this tiny beast, we would never mistake it for a member of the animal kingdom. But we would nevertheless find in its repertoire a handful of skills that were going to prove useful in the evolution of animals.

Evolution took the materials that were available – the ability to make different kinds of cells; to stick those cells together; to regulate the number of cells and so on – and tinkered with them. From these beginnings, natural selection would then do its thing, resulting, 600 million years later, in the amazing diversity of the animal kingdom from jellyfish to flies, tapeworms, starfish and you.
