Ancient tooth proteins suggest ‘Homo erectus’ may have left a genetic legacy in people today

Source: The Conversation – UK – By Sally Christine Reynolds, Associate Professor in Hominin Palaeoecology, Bournemouth University

For most of the 20th century, the model of human origins was a tree: with the trunk dividing into branches, and then twigs. Each species of human relative (hominin) was a neat, single branch.

As an undergraduate, I was taught that Homo sapiens was one of these branches that emerged in Africa, spread across the world, and displaced every archaic human it encountered.

Neanderthals, Homo erectus, and other ancient relatives were evolutionary dead ends – unfortunate cousins who left no descendants. In the 30 years since I left university, those early lessons are now radically revised.

That neat replacement story is now comprehensively wrong, largely thanks to studies like the one published in Nature this week by Qiaomei Fu from the Chinese Academy of Sciences and colleagues. The paper achieves something that would have seemed impossible a decade ago: it recovers meaningful biological information from H. erectus fossils far too old for DNA.

Instead of genetic sequences, the team extracted ancient proteins from the enamel of six teeth from three Chinese sites – Zhoukoudian (which, in the early 20th century, produced fossil remains known as “Peking Man”), Hexian and Sunjiadong – all dating to around 400,000 years ago.

Homo erectus is widely regarded as the first hominin to leave Africa; the evidence suggests this species had moved into Eurasia nearly two million years ago. It remains the most geographically widespread human ancestor that ever lived. The new study indicates that Homo erectus exchanged genes (probably through interbreeding) with Denisovans in East Asia roughly 400,000 years ago.

The study suggests that some of that genetic legacy, it now appears, was passed on to living people in the Philippines, Papua New Guinea, and across south-east Asia.

Tooth enamel is the hardest tissue in the body, and its proteins survive long after DNA has degraded beyond recovery. What the team found in those proteins is striking. All six specimens share a previously unknown amino acid variant – a tiny molecular signature, a single letter changed in the protein sequence, never seen in any other hominin alive or dead.

This variant clusters these east Asian H. erectus into a distinct group, confirming their identity and settling a long-running debate about whether the unusual Hexian fossils were H. erectus at all. A second variant they share, however, is not unique to H. erectus.

It also appears in Denisovans – a mysterious archaic (non-Homo sapiens) human group known mainly from a cave in Siberia. The corresponding genetic variant turns up in living people at frequencies of 21% in the Philippines and about 1% in India, distributed in a pattern that matches what we’d expect if it entered modern humans via Denisovan ancestry.

The most reasonable interpretation is that H. erectus populations in east Asia passed this variant to Denisovans through interbreeding, and Denisovans later passed it on to the ancestors of modern south-east Asians and Oceanians. This transfer of genetic material from one species to another is known as introgression.

The lineage we once thought was a dead end has, it turns out, left a small but detectable trace in living human genomes – a molecular thread connecting a Peking Man tooth to living people in Asia.

A pattern repeated

But the significance of today’s paper extends well beyond the specific variant or the specific populations involved. What it really shows is that interbreeding between archaic human lineages was not exceptional. It was routine.

Every major hominin lineage we have been able to examine genomically shows admixture. Modern humans outside Africa carry roughly 2% Neanderthal DNA. Papuans and Aboriginal Australians carry an additional 2–5% Denisovan ancestry.

West African populations carry genetic signatures from an unidentified archaic lineage. Even Denisovans themselves, as today’s study adds further weight to, received gene flow from something older and more diverged — likely H. erectus.

A 2019 review in the American Journal of Physical Anthropology documents at least three distinct introgression events from Denisovan-like populations into south-east Asian and Oceanic ancestors alone, some occurring as recently as 20,000 years ago. The picture is not one of clean lineages but of a tangled web of contact and exchange extending across millions of years.

The implications are far-reaching. Our genomes are not the product of a single unbroken lineage emerging from Africa. They are mosaics, assembled from contributions by multiple archaic groups, each adapted to its own regional environment.

Some of the Denisovan-derived variants in Papuan genomes, for instance, appear to influence immune function. The H. erectus-derived variant identified today has unknown functional consequences – that remains an open question – but the precedent from other gene variants that have introgressed (genes that have passed from one species into another) suggests that adaptation to new environments may have been part of the story.

Ghost populations

Perhaps most intriguing is what the new paper implies about all the populations we cannot yet study. H. erectus survived in Indonesia until perhaps 100,000 years ago. Homo floresiensis, the diminutive “hobbit” species, was present on Flores when modern humans arrived. Another human lineage, Homo luzonensis, occupied the Philippines.

None of these populations have yielded DNA, and until today none had yielded any molecular data at all. Were they also absorbed, at least partially, into the human populations that replaced them? The genomic evidence from living people has not, so far, detected their signal clearly – but the tools available until recently were blunt instruments.

The proteomic approach demonstrated in today’s paper offers a way forward. If proteins can be recovered from H. erectus enamel at 400,000 years, the same approach applied to floresiensis or luzonensis material might finally reveal whether those lineages, too, contributed something to the humans who came after them.

The old metaphor of a tree – a single trunk branching into distinct species – has been quietly replaced in the scientific literature. It might be better to consider the process as a braided river, with many channels running partly together and partly apart, exchanging water continuously.

This new study is one more confirmation that when ancient human populations disappeared, they left traces of themselves behind.

Why indie sleaze feels nostalgic – even for people who never lived it

Source: The Conversation – UK – By Lucy Bennett, Lecturer in Popular Music, Digital Culture and Fandom, Cardiff University

Scrolling through social media, it feels as though “indie sleaze” never went away. Grainy flash photography, smudged eyeliner and a soundtrack of early 2000s indie music are once again dominating feeds.

This revival is more of a reworking than a straightforward comeback. Today’s indie sleaze – exemplified in the music video for Charli XCX’s new track, Rock Music – is an algorithmically curated version of a once messy, participatory subculture. Its renewed appeal seems to lie partly in this aesthetic of imperfection, partly in its connection to earlier digital platforms and partly in what it evokes – a specific cultural moment associated with pre-social media digital life.

The original “indie sleaze” moment emerged in the early-mid 2000s, connecting with music, fashion, nightlife and online culture. It coalesced around a wide mix of genres, including electro and “indie” rock, particularly bands from New York such as The Strokes and Yeah Yeah Yeahs, and in the UK The Libertines, Long Blondes, Arctic Monkeys and Franz Ferdinand. However, it was it more than just the music – the visuals and lifestyle played a core part.


No one’s 20s and 30s look the same. You might be saving for a mortgage or just struggling to pay rent. You could be swiping dating apps, or trying to understand childcare. No matter your current challenges, our Quarter Life series has articles to share in the group chat, or just to remind you that you’re not alone.

Equally important were the digital platforms that enabled new forms of fan participation and visibility. Sites like MySpace, LiveJournal and later Tumblr, allowed fans, bloggers and photographers to document and curate the scene in real time.

These platforms operated differently from today’s social media environment. They were less centralised or driven by algorithm recommendation, allowing different music scenes to emerge more gradually and at times unevenly across networks of different users.

Rock Song by Charli XCX taps into indie sleaze nostalgia.

As media researcher Henry Jenkins has argued, spaces like these foster forms of participatory culture, in which audiences actively shape and circulate media, often connecting with their own personal pleasures. Indie sleaze deeply connects with this, being a scene produced as much through fan practices such as blogging, photographing and sharing, as through the music itself.

What’s changed

The current revival can be traced back to a viral TikTok trend forecast in 2021, which predicted that the scene would be returning and gave it its specific name and coherence. Nobody was describing the scene as “indie sleaze” during its original heyday.

Since then, TikTok “indie sleaze” content has circulated through recognisable formats such as “get ready with me” videos styled for nights out or themed parties, slideshows of grainy flash photography, makeup tutorials and nostalgic edits imagining early 2000s club culture.

This is supplemented by accounts such as the curated @indiesleaze on Instagram, which highlights the importance of earlier platforms such as Flickr in documenting the scene. It allows followers to contrast the media we had then and its dynamics, with what we have now.

What stands out about this revival is its relationship to nostalgia. Many of the TikTok users producing indie sleaze content now were too young to have experienced the original scene. Instead, they engage with it through fragments such as archived images, music playlists and viral videos that reconstruct the past as a particular aesthetic and feeling. As a result, what circulates is not the lived reality of mid 2000s nightlife, but a stylised and selective memory of it.

For some music fans, this nostalgia is about a different experience of digital culture – one that feels less dominated by platforms, filters, AI and algorithms. For those who lived through indie sleaze, this revival may also produce a different kind of nostalgia that rests on memory.

On platforms like TikTok, “indie sleaze” has become a template that others can engage in through a set of visual cues and references that can be easily reproduced and widely circulated. This suggests that it is precisely indie sleaze’s messiness that makes it appealing and draws some people in. Its grain, blur and imperfection offer such a stark contrast to the polished, filter heavy and increasingly AI-mediated environments that characterise much of our contemporary social media.

There is also a sense of irony here. While indie sleaze is often appealing because of its rawness and imperfection, some of these visuals are now recreated through the very technologies they seem to resist. Filters and editing apps can add effects to smartphone images, digitally reproducing the look of older cameras and online photography. In this sense, the messiness associated with indie sleaze is no longer entirely spontaneous, but increasingly stylised for social media platforms.

Similar dynamics were at play in the reception of Charli XCX’s Brat album in 2025, which also resonated with audiences through its deliberately bold, messy, self aware aesthetic.

Brat by Charli XCX is a work of contemporary imagist poetry – and a reclamation of ‘bratty’ women’s art


Music is often used by fans to connect to another time, whether through memory, or imagined pasts, bringing a sense of these moments into the present. In this sense, the return of indie sleaze is not simply a revival of a past musical movement, but a nostalgic reworking of it in the present.

As I have explored in previous research with Rafal Zaborowski on the resurgence of Kate Bush on TikTok, such revivals are often shaped by the logics of the platforms through which they circulate, connecting with forms of affect or nostalgia. What emerges then is not a faithful reconstruction or revival, but instead a version of the past that is made visible, shareable and open to reinterpretation in new ways and to new generations.

Ultimately this revival tells us as much about the present as it does about the past, raising broader insights about how digital platforms are reshaping not just what music fans remember, but the ways in which those memories are formed and shared.

Drug shortages continue to be a problem in the UK – yet strengthening supply chains alone won’t solve this issue

Source: The Conversation – UK – By Emilia Vann Yaroson, Assistant Professor in Operations and Supply Chain Management, University of Sheffield

The UK continues to experience shortages of many common prescription drugs, despite efforts to strengthen supply chains.

Drugs for ADHD, epilepsy, GLP-1s for type 2 diabetes and weight loss, as well as ramipril (which is used to treat high blood pressure and heart failure), have all faced supply shortages since the end of last year or beginning of this year.

As products become unavailable, pressure increases across the system to secure alternatives. If patients do not receive treatment promptly and consistently, their quality of life can suffer.

Medicine supply shortages pose a significant threat to the UK’s public health. And, as a recent government inquiry revealed, the UK’s current medicine supply chain is very vulnerable to disruptions.

Making supply chains more resilient would normally have been the best strategy for ensuring the UK can maintain supplies of medicine and recover quickly when problems do occur. But growing global and supply chain pressures mean medicine shortages are likely to continue unless deeper system weaknesses are addressed.

Why shortages keep happening

Medicine supply chains are global, highly regulated and complex. Challenges such as factory maintenance, transport delays or rising demand in other countries can quickly affect medicine supplies in the UK.

Recent disruptions, such as the Iran conflict, have raised concerns about future medicines security. The war has already driven up the cost of some prescription drugs by 30%. This is largely due to the jump in gas and diesel prices, making manufacturing and shipping more costly.

The rising cost of raw materials and energy can also contribute to increasing drug costs for patients and healthcare systems.

The supply and demand for medicines can fluctuate as well depending on disease prevalence, access to diagnosis, market pricing and people’s ability to pay. For instance, ongoing HRT shortages have partly been blamed on increased demand for the drug following GP consultations.

It can therefore be challenging to ensure a constant supply of medication. But this is not just a UK issue – it’s a worldwide problem.

The UK competes globally for access to medicines and critical ingredients. Approximately 80% of the medicines used to treat UK patients are non-branded or “generics”. These are mainly manufactured in China and India. Generics are clinically effective but less expensive than branded drugs, so there’s a heavy reliance on them internationally.

China and India are also the primary manufacturers of many basic pharmaceutical ingredients. This increases global reliance on these countries. Manufacturing problems or transport delays in these countries can quickly reduce worldwide access to medicines.

Community pharmacies, which buy the medicines dispensed to patients in the UK, are directly affected by drug shortages. When medicines are not available and demand exceeds supply, market prices can rise quickly. These independent businesses may therefore be financially challenged by drug prices.

Although the Department of Health & Social Care (DHSC) has agreed prices and will refund pharmacies for the medicines they buy, the pharmacies can still make a loss on the purchases – and DHSC payments are always in arrears.

Patients usually access their medications through their local community pharmacy. But in the past five years, more than 1,000 community pharmacies have closed in the UK. Some of the causes of these closures are directly related to drug supplies, including medicine reimbursement and pressure due to shortages. Closing local community pharmacies puts pressure on the remaining pharmacies to maintain stock.

If patients cannot access their medicines, it can trigger panic orders and stockpiling, which may place even greater pressure on already fragile supply chains and waste. In some cases, these shortages also create opportunities for counterfeit medicines to infiltrate the market, as desperate patients seek alternative sources to meet their needs.

Low medicine prices have also been cited as a key reason for suppliers leaving the market or companies such as AstraZeneca reducing UK investment.

A lack of timely and informative communication about prescription drug shortages can lead to patient concerns, providers panicking and trading opportunism. Patients do not know why they can’t access their medicines or how long the situation will last.

What can we do?

There are calls from within the sector for earlier signalling of supply issues and changes in demand. This would give UK suppliers more time to find alternative medicines, plan production schedules, reduce delays and disruption and hopefully better prevent medicine shortages.

Effective and timely communication is also needed to support providers in doing their jobs and allay patient concerns.

Focusing on the pricing of medicines and its wider impact on our healthcare system is another important factor. The UK Life Sciences Sector Plan aims to support the sector and attract investors to strengthen local medicine production and reduce the impact of medicine shortages.

Educating stakeholders can help reduce medicine shortages by improving awareness, coordination and responsible behaviour across the supply chain. Educating community pharmacists and patients of the causes and impact of medicine shortages is also key. This can reduce panic orders, unnecessary stockpiling of medicines and prevent counterfeit or unregulated products entering the market.

The UK government should also collaborate more extensively with European partners by sourcing products from trusted or geographically close countries. This would not only promote stronger relationships but also create direct access to alternate medicine supply sources.

The current market leaders benefit from economies of scale and scope, however. More local and distributed manufacture may be stable but expensive. Key ingredients still often have single (or few) sources.

Improving supply resilience is essential for maintaining the availability of prescription drugs and reducing service pressures. But it isn’t the only strategy the UK government should rely on. Appreciation of the role of the patient and the provider as recipients is important in managing the impact and continuity of supply issues.

For patients experiencing shortages, it’s important you don’t panic buy and stockpile items, and continue ordering your prescription only when needed. Your pharmacist can also give you advice on what to do if your usual medicine is not in stock.

Mali’s military leader is consolidating power. Why this is dangerous

Source: The Conversation – Africa (2) – By Salah Ben Hammou, Postdoctoral Research Associate, Rice University

Malian officials announced on 4 May 2026 that junta leader General Assimi Goïta would take on the post of defence minister after the killing of General Sadio Camara a week earlier.

Camara’s death occurred amid an offensive by the Azawad Liberation Front (FLA) and Jama’at Nusrat al-Islam wal-Muslimin, which launched attacks across Mali. Insecurity persists in Mali despite years of military rule, which was justified on promises of restoring order and defeating insurgent violence.

On the surface, Goïta’s decision to absorb the defence portfolio appears to be a pragmatic wartime measure, aimed at ensuring continuity within the armed forces during a period of instability.

But the move also follows a broader political path that has become visible in Mali since the junta seized power in 2020. Rather than institutionalising military rule, Goïta has concentrated authority around the presidency, tightened control over the state’s coercive apparatus, and relied on a small circle of military elites.

As political scientists who have extensively published and written on military coups and regime trajectories in west Africa, we observe this behaviour is not unique to Mali. It is the third country in the region to see military leaders consolidate their authority around individual leaders rather than the armed forces.

Across the post-coup Sahel, military regimes have shifted from presenting themselves as temporary “corrective” interventions to becoming personalised systems of rule. The other two examples are Captain Ibrahim Traoré, who took power in Burkina Faso in September 2022, and Niger’s General Abdourahamane Tiani, who seized power in July 2023.

The distinction matters because military regimes governed collectively by officer coalitions retain some internal balance and institutional constraint. As power becomes concentrated around a single ruler, however, decision-making revolves around personal loyalty rather than broader military or state interests.

Military rule and personalisation in Mali

Goïta (then a colonel) and his companions in Mali toppled President Ibrahim Boubacar Keita in August 2020. The coup architects initially presented themselves as reluctant interveners. At the time, observers expected a short transition. Within months the regional body Ecowas had lifted its financial embargo.

Goïta pledged elections within 18 months, then 24.

A constitutional revision passed in 2025 removed the provision that had previously barred him from standing in any future presidential election. Political parties were banned. The transitional legislative body was filled by presidential decree. And civilian oversight institutions, including the electoral observation body, were dissolved.

The armed forces were restructured along lines scholars recognise as counterbalancing. This is best described as a coup-proofing mechanism. Regimes create parallel armed structures with distinct reporting lines to make it more difficult for any group to move against them.

In Mali, three specialised military units were created with overlapping counter-terrorism mandates that report to the executive. The police were also placed under military discipline.

Goïta assumed the defence portfolio, appointed the former chief of staff of the armed forces, Major General Oumar Diarra, as delegate minister, and named a new chief of staff to replace him.

The defence portfolio controls the largest share of the state budget, grown from 11.5% to 14.5% of GDP since 2020. It is where Mali’s relationship with Africa Corps, which since 2023 has replaced French forces in counter-terrorism operations, is managed daily.

As defence minister since the coup, Camara had been the primary link with Africa Corps.

The appointment of Diarra is consistent with what scholars describe as the rotation of commanders to limit the accumulation of loyalty around any single figure. Diarra had served as chief of staff since 2020.

Burkina Faso and Niger

In Burkina Faso and Niger, too, there have been signs that military regimes are concentrating power around individual military leaders rather than a collective of officers.

Traoré is perhaps the clearest example of this trend. Since seizing power in 2022, he has cultivated an image of himself as a revolutionary anti-colonial figure, drawing comparisons to the iconic Burkinabè leader Thomas Sankara.

Coordinated social media campaigns glorified Traoré while attacking critics. This was combined with nationalist rhetoric and highly publicised economic reforms. All helped elevate his image as the symbolic saviour of Burkinabè society.

Allegations of assassination attempts and coup conspiracies helped rally public support around Traoré as a besieged national leader. They also served as valuable pretexts for targeting political opponents and rivals in the military.

Traoré has appointed family members and trusted allies to strategic positions. Individuals like his brother, Inoussa Traoré, hold senior positions and help curate the regime’s digital message while maintaining links with sympathetic civil society.

Elections are repeatedly delayed and Burkinabes are urged to “forget about democracy”. Traoré is slated to remain in power until 2029.

In Niger, Tiani, the former commander of Mohamed Bazoum’s Presidential Guard, has extended his rule until at least 2030.

Much like Goïta, he has made the timeline conditional on the state of the country’s security.

Tiani dissolved political parties, promoted himself to army general, a first in Niger, and was cast as a national hero. He has reportedly retreated almost entirely from public life and conducts government from within the presidential guard compound.

From there, Tiani has militarised the civilian administration and placed trusted figures around him. General Salifou Mody at defence serves as his principal relay with Russian partners and with the chief of staff of the armed forces, General Moussa Salaou Barmou.

The regime also moved to repress political opponents through civilian-facing institutions, such as the Commission de lutte contre la délinquance économique, financière et fiscale.

The perils of personalism

For decades, political scientists have highlighted the dangers and weaknesses of personalist political systems. Concentrating power around a single ruler often weakens the institutions needed for effective governance and long-term stability.

In military-ruled countries like those in the Sahel, the consequences can be especially severe. Armed forces may be reorganised less around operational effectiveness than around protecting the ruler from rivals and internal threats.

Promotions and command positions become tied to loyalty, parallel security structures proliferate, and mistrust within the officer corps deepens. On the battlefield, these dynamics can undermine coordination and reduce the military’s ability to respond effectively to insurgent violence.

Trump’s ‘cordial’ Beijing trip has not changed superpower rivalry

Source: The Conversation – UK – By Maria Ryan, Associate Professor in US History, University of Nottingham

Donald Trump’s appraisal of his recent state visit to China was, typically, positive and self-regarding. At the end of the trip, the US president told reporters that it had achieved “a lot of good” and “fantastic trade deals” had been signed. He concluded that a lot of different problems were settled “that other people wouldn’t have been able to solve”.

As usual, the US president appeared to enjoy the pageantry of a state visit. He likes meeting other “great” leaders – strongmen who lead powerful countries.

At face value, the trip appeared largely successful. The Trump-Xi relationship appeared cordial. There were no undiplomatic comments by Trump. Xi described it as “a milestone visit” of “historic” proportions. Trump said that his relationship with Xi is “a very strong one”. China pledged to buy 200 Boeing aircraft and also committed to buying billions of dollars of soybeans and other agricultural goods. These are all things Trump can present as wins, even if their significance is disputed.

The cordiality of the visit was a contrast to the Biden years, when “extreme competition” with China – in Biden’s words – was the central organising principle of US foreign policy. The Biden administration viewed China as a once-in-a-generation challenger to US power: politically, economically, militarily and ideologically. It believed Beijing was aggressively trying to displace the US as the world’s dominant power and actively sought to prevent this.

Over the past year, the second Trump administration has shifted attention away from great power conflict with China and focused on other things. These have included regime change in Venezuela (and, all the signs suggest, Cuba is now in his sights). He has changed America’s relationship with Europe, introduced an at-times erratic regime of tariffs in an attempt to address US trade deficits. And, above all, he has started a war with Iran.

Ely Ratner, a China hawk from the Biden administration has accused Trump of “strategic deference” towards Beijing. And there can be little doubt that the Trump administration has dialled down the Cold War-style ideological rhetoric about China.

Its 2025 national security strategy stresses that: “We seek good relations and peaceful commercial relations with the nations of the world without imposing on them democratic or other social change that differs widely from their traditions or histories.” This much was evident from Trump’s visit. Unlike Biden, Trump did not publicly raises human rights issues on his trip to China. This removed a persistent irritant in the relationship.

That said, the US Congress – and many of those around the president – still see the relationship with China as fundamentally competitive and adversarial. They want the US to remain the world’s primary power, militarily, economically and technologically. The desire to out-compete China is likely to drive policy in the longer-term.

The 2026 national defense strategy, published in January, states that Washington will be “clear-eyed and realistic about the speed, scale, and quality of China’s historic military buildup” and will “prevent anyone, including China, from being able to dominate us or our allies”. The strategy commits the US to deterring a Chinese invasion of Taiwan by keeping “a strong denial defense along the First Island Chain” north and south of Taiwan. The US secretary of state, Marco Rubio, who accompanied Trump to Beijing, confirmed that US policy on Taiwan has not changed as a result of the leaders’ meeting.

The Trump administration’s approach is driven primarily by economic interests. This is because it believes that “the Indo-Pacific will soon make up more than half of the global economy” and, according to the defense strategy: “Were China… to dominate this broad and crucial region, it would be able to effectively veto Americans’ access to the world’s economic center of gravity.”

This means the Trump administration will try to preserve the giant US military presence in Asia Pacific that the Chinese see as encirclement.

‘Conscious de-coupling’

The US president remains a mercurial character who can make unpredictable decisions. He likes to tout his prowess as a dealmaker and it is always possible that he could undermine the consensus view within his own government. But the US Congress is also firmly behind the drive to out-compete China and to “decouple” in advanced technology.

In July 2025, the bipartisan “One Big Beautiful Bill” Act (OBBBA) included US$58 billion (£43.5 billion) of federal investments in, and tax incentives for, AI production inside the US. These measures barred “prohibited foreign entities” from US supply chains. In 2018, Congress passed strict new export controls and investment restrictions into law to try to decouple from China in emerging new technologies. The House Select Committee on China is pushing for more of this.

Over the past year, the Trump administration launched a new strategy for rare earth metals. China’s dominance of the mining and processing of these metals is a huge advantage – they are critical to modern weapons systems and widely used in electronics, from smartphones to EVs.

In April 2025, Beijing began to impose export controls on rare earths in response to US tariffs. Since then, the US has launched a US$7.3 billion global effort to secure supplies of rare earths outside China and invest in domestic mining and processing capabilities. While this will take years to come to fruition, the goal is to speed up decoupling from China in rare earths – hardly a sign of trust.

Finally, Trump reportedly refused to extend the trade truce signed in October 2025 until the end of his administration as he believed he would lose leverage over China in future. It’s a clear sign that even he expects tension in future.

The Trump administration says that, unlike its predecessors, it is not looking for conflict with China. But its insistence on US dominance of Asia Pacific is likely to drive competition with China in the long-term.

Labour in crisis: whoever is prime minister, voters expect politicians to use the language of populism

Source: The Conversation – UK – By Stephen Coleman, Emeritus Professor of Political Communication, University of Leeds

Beyond the high drama surrounding the Makerfield by-election and the contest to be the UK prime minister lies a more fundamental battle. It is the struggle between the incremental pragmatism of mainstream politics and the magical thinking of populism.

The great catchword of recent UK politics has been “change”. Brexit, it was said, would change the country’s declining position in the world. Boris Johnson said after his landslide electoral victory in 2019 that he was going to take on “the problems that no government has had the guts to tackle before”.

Labour’s 2024 election manifesto, entitled “Change”, declared that a Starmer-led government would “stop the chaos, turn the page, and start to rebuild our country”.

But people have different ideas of what change means and how fast it can happen.
In a world full of entrenched, unequal social structures and complex, intractable
global problems, change is inevitably a long-term project. But voters tend not to be in the business of long-term evaluation.

Similarly, they are not impressed by graphs showing that the UK economy is currently the fastest-growing in the G7 or that waiting times for NHS treatment in England are at their lowest level in more than three years.

There are undoubtedly better ways of communicating long-term change and
identifying quick wins than the current government has adopted. However, the real battle is not between rival tellers of the mainstream narrative, but between two completely different conceptions of change. Remembering this will be crucial for Andy Burnham when he takes on Reform UK in the Makerfield by-election in his bid to return to Westminster to challenge Keir Starmer for the leadership of the Labour party and his job as prime minister.

Feelings over facts

Populist leaders are successful not because they have more convincing policies for house-building, ending child poverty or realising energy security. The change they offer appeals to visceral feelings rather than material needs. “Imagine how you will feel on the day that we come to power,” they say. “Think of how shattered all of those people who have ignored you, talked down to you, taken your jobs and pushed ahead of you in the queue for services will feel.”

Populists such as Reform UK (according to current polls the most likely party to win the next UK general election) are less interested in setting out a policy programme than in connecting with voters’ raw nerves.

That is why the most crucial lesson for Labour from the 2026 local elections
was not their devastating defeat, but the unstoppable surge of Reform’s appeal to
voters that threatened to leave them in the margins in the next general election.
Labour’s reflex response was to depose its leader. And possibly at least one of Starmer’s rivals for the job would be more effective at taking on this new form of political opposition.

More important, however, is to be clear what is involved in taking on
populism. A new prime minister will be faced with exactly the same challenges as
the current one and will not be able to deliver transformative change simply by force of an appealing personality.

Europe will still be involved in its longest war since 1945. The US will continue to be an unreliable partner. The climate emergency will go on wreaking havoc. Social care for an ageing population will remain a massive challenge. National debt will still limit the capacity for public investment. Regional disparities and indefensible social inequalities will still exist.

All of these challenges and more will result in sections of the electorate feeling alienated and disappointed – the very sentiments upon which populism depends.

The big question for whoever is going to be prime minister in the next three years is not just about policy and delivery (although it is also very much about that), but about offering an alternative to the psychic appeal of populism. That will entail adopting a three-point strategy.

First, politicians need to acknowledge the depth of disappointment felt by people whose parents and grandparents had once believed that the government was there to look after them in times of need. The prime minister should declare an urgent mission to build an infrastructure of cradle-to-grave care, which exists not to tell people how they should be feeling, but to be democratically accountable to their needs and priorities as individuals and communities.

Second, there is a need for a complete overhaul of political language, led by the prime minister’s example, eschewing the lexicon of technocratic cliche and adopting the conversational tone of speaking with rather than speaking at people.

Third, there is a need for boldness in calling out the ugly sentiments of populism and appealing explicitly to the more generous, positive feelings and beliefs of the majority that are too often excluded from the domain of hardheaded politics.

A new prime minister will need to be imaginative in demonstrating that populists are not the only ones who can appeal to people’s deepest apprehensions and desires. And they will have to show that politics can be more like an inclusive conversation than a PowerPoint presentation. In that case, then perhaps the recent soap opera will not be as inconsequential as many people perceive it to be.

A newly rediscovered moth species in Florida may already be at risk

Source: The Conversation – USA – By Ryan St Laurent, Assistant Professor of Biology, University of Colorado Boulder

For decades, the Florida sack-bearer moth was hiding in plain sight among collections of other sack-bearer moths around the U.S. Ryan St Laurent

To the untrained eye, the Florida scrub ecosystem isn’t much to look at. Scattered in patches around coastal and inland Florida, the scrub landscape is dominated by shrubs and short oaks, all growing out of sandy soil.

“Scrub” is truly an apt name for it.

But this habitat is home to a number of unique plant and animal species, including the threatened Florida scrub-jay, the only bird found only in Florida.

The list of specialized scrub animals grew longer this spring when I officially named – and found in the wild – a species of moth unique to the Florida scrub.

I’m an evolutionary biologist and entomologist, serving as curator of entomology at the University of Colorado Boulder Museum of Natural History. In March 2026 I, along with my collaborators, Scott Wehrly and Jeff Slotten, published an article in ZooKeys describing this new moth from the Florida scrub.

I colloquially refer to it as the “Florida sack-bearer,” but it’s formally known as Cicinnus albarenicolus, Latin for “white sand dweller.” The name “sack-bearer” indicates that it belongs to a small family of moths known as Mimallonidae whose caterpillars make sacklike cases that they haul around, kind of like the way a hermit crab carries around a shell. There are just over 300 sack-bearer species, with only six, including our new one, known from North America.

The discovery

The recent publication of our scientific paper was the first time the scientific community learned of the moth’s existence, but it is the culmination of more than a decade of work.

I have been studying sack-bearers throughout my professional career, which started as an undergraduate at Cornell University, where I worked in the Cornell University Insect Collection. It was in this collection that a small sample of sack-bearer moths collected in Florida, with a chunky body and pink-hued wings spanning about 1.25-1.5 inches (3-4 centimeters) – medium size for a moth – caught my eye.

I began to wonder whether perhaps this moth was a separate species of sack-bearer, because it looked quite different from the more beige-colored Melsheimer’s sack-bearer that is common all over the eastern United States, including Florida. But I did not yet have enough data to substantiate my theory.

Then as a graduate student at the University of Florida, I delved into learning more about sack-bearer evolution. Whenever I had a free moment, I spent time in the field looking for wild individuals of the still-unnamed Florida sack-bearer. But still, no luck.

Then I spent three years as a postdoctoral fellow at the Smithsonian National Museum of Natural History. Even though I was primarily working on a completely different group of moths, I had not forgotten about the Florida moth. And there, in the Smithsonian collections, I found a single specimen of a Florida sack-bearer from 1960.

Fortunately, it was a recent enough specimen to yield a good DNA sample. This allowed me to get the final piece of information that I was looking for: a DNA sequence to confirm that this moth was distinct from its relatives.

The genetic results were unequivocal: The Florida species was clearly distinct, thus confirming my long-held suspicions that this was a new, undescribed species of moth. This was the final piece of information I needed to start writing the paper formally describing and naming the new moth.

Encounter in the wild

As excited as I was to describe a new species, I feared that the moth might already be extinct, since no recent specimens existed and the Florida scrub habitat is highly degraded, down to about 10% of what ecologists estimate was present prior to European settlement.

But I contacted various moth collectors in Florida to see whether anyone had seen this moth recently, and to my surprise one of them had. The co-authors on the Zookeys paper, Jeff Slotten and Scott Wehrly, helped me discover a small set of specimens from the 2010s and 2020s that Scott had collected. This discovery, in late 2025, allowed me to add some new specimens to the paper and update the text reporting this newly discovered collection of more contemporary samples of Florida sack-bearers.

Knowing that all sightings of this moth occurred between March and May, I traveled to Florida in April. I was hoping to see it for myself and learn more about its active times, habitat requirements, diet, mating habits and other aspects of its biology – all still completely unknown. Since the recent specimens were all male, I set the goal to find a female, which would be the first one seen in over 60 years. Finding a female would also be an opportunity to collect eggs.

On April 18, 2026, I traveled to a new site that I had scoped out back in grad school, and sure enough, at 8:49 p.m., I found a female at my specialized moth light trap. This female was followed by two others, and I was able to collect eggs. Hopefully this summer these will yield a bunch of caterpillars so my colleagues and I can observe the moth’s full life cycle and learn more about this elusive insect.

What makes the Florida sack-bearer so special?

Without knowing more about it, it’s challenging to articulate what this moth’s larger role in the ecosystem might be. And that is precisely why this discovery is important.

One possibility that is already becoming clear is that this species may be an excellent indicator of Florida scrub health and how different forest management techniques affect the scrub ecosystem. My recent field work indicates that this particular moth may be thriving in areas experiencing more recent and frequent prescribed burns, but this hypothesis needs further study. My hope is that studying this moth will give a better sense of how to manage scrubs in order to protect this and other species with similar habitat requirements.

The evolution of the Florida sack-bearer also remains a puzzle. Just how did it get to Florida in the first place? White sand scrubs are thought to be older than yellow sand scrubs of Florida and are formed from ancient sand dunes. Perhaps the Florida sack-bearer is an ancient relic of a time when Florida was very different from today.

By studying this moth and its distribution in the state, we may better understand how sack-bearers arrived in North America from Central and South America millions of years ago.

What’s in a name?

In total, only 19 specimens of the Florida sack-bearer were known to me at the time of its formal description. Only three of those were collected after 1964, and those all came from locations near Ocala, Florida. The other 13 specimens are from just five white sand scrub habitats scattered across peninsular Florida. While the news that the moth persists in at least a couple of places is welcome, sites that supported this moth back in the 1960s may no longer have enough scrub habitat due to substantial habitat loss.

It’s possible that this moth has been discovered just in time to realize it’s at risk of going extinct. But my hope is that by naming this rare moth, our team has enabled conservationists and legislators to fight for its protection.

Dark patterns on the web are designed to manipulate you – why aren’t they all illegal?

Source: The Conversation – USA – By Gregory M. Dickinson, Assistant Professor of Law, University of Nebraska-Lincoln; Institute for Humane Studies

Website designs that try to change your behavior cross a line when they outright deceive. Fizkes/iStock via Getty Images

You open a free app to do one simple thing. Before you even start, a full-screen message asks whether you want to try the paid version. The “Start free trial” button is large, bright and hard to miss. The option to keep using the free version is smaller, buried at the bottom. The same prompt appears again tomorrow. And the day after that.

A lot of people look at screens like that and think, “Surely this has to be illegal.” We even have a name for them, “dark patterns.” They feel pushy. They waste time. They seem designed to wear you down. But in most cases, they are perfectly lawful.

“Dark pattern” is not a legal term with a clear boundary. It is a broad label for digital designs that nudge, pressure, confuse or trap users. As a legal scholar who studies consumer protection and digital design, I think the most important thing for readers to understand is that the label “dark pattern” covers a broad spectrum.

Some of that spectrum is just annoying. Some of it is aggressive salesmanship. And some of it crosses the line into deception or coercion. Federal and state consumer protection laws are mostly aimed at that last category. They do not ban every design choice people dislike, only those that trick or coerce.

Annoying isn’t illegal

The ad also has an ‘X’ in the upper left corner, which is part of the image in the ad. Some users might click the ‘X’ on the left to dismiss the ad but instead be sent to the ad’s website. Possibly annoying but not illegal.

That reality may sound unsatisfying, but it is not unusual. Offline life is full of things that are irritating but not unlawful. Think of the cashier who asks whether you want to sign up for the store credit card, then points out the discount you are turning down, then asks again. Most people know exactly what is happening. They roll their eyes, say no and try to shop somewhere else next time.

The same is true online. A repeated pop-up can be obnoxious. A guilt-inducing button can be tacky. But consumers recognize ordinary annoyance for what it is. In many cases, the market answer is simple: Close the app, ignore the pitch or take your business elsewhere.

Similarly, law does not ban persuasive sales pitches just because they are effective. A car salesperson who keeps steering you toward the upgraded model is trying to influence your choice. So is the airline clerk who offers travel insurance. So is the restaurant server who asks whether you want dessert. Salesmanship is nothing new. Digital design often borrows from familiar techniques.

That helps explain why lawmakers cannot simply outlaw “manipulation.” And so many interfaces are built to persuade, openly and lawfully.

What crosses the line

What the federal FTC Act and analogous state consumer-deception statutes usually care about is not whether a design is annoying. They focus on whether the design is likely to mislead a reasonable consumer. That is the core idea in modern consumer protection law.

So a design is likelier to be unlawful when it hides key facts, makes an optional choice look mandatory or tricks people about the effect of the button they are pressing. A fake countdown timer, a disguised ad, a misleading one-click purchase button or a cancellation path that looks finished when it is not are all different from ordinary hard selling. Those designs do not just pressure users; they can deceive them.

That is also why the app maker’s intent is not always the key question. In many consumer protection cases, a company does not get a free pass just because no one said, “Let’s trick people.” The legal question is often about effect: What would a reasonable user likely understand from this screen?

Research on dark patterns reinforces that concern. Even relatively mild designs can push people into choices they would not otherwise make. And regulators have increasingly focused on subscription flows, hidden fees and cancellation obstacles for exactly that reason.

The instructions for this web form and the pop-up box that appears when users click ‘Continue’ indicate that the form has required fields. The form uses the word ‘mandatory,’ which could lead some users to believe that the form itself is required in order to continue when it is instead optional. Possibly annoying but not illegal.

Why it feels like dark patterns are everywhere

One reason people might think there are no laws against dark patterns is that they see them so often. But that frequency reflects that the term covers a wide range of conduct, from lawful nagging to outright deception.

It also reflects enforcement limits. Regulators cannot chase every irritating screen on every app and website. They have to prioritize the worst cases. That leaves a lot of borderline conduct in the wild, which makes the whole problem feel bigger and murkier to ordinary users.

So when people ask why there is not a law against dark patterns, the best answer is that there already is, but the law does not prohibit every annoying or high-pressure design. It targets lies, misleading cues and coercive obstacles.

That line can be fuzzy. But the fuzziness is not a mistake. It is what you get when the law tries to separate persuasion from deception in a world full of both.

What are those orange balls on some power lines?

What are those orange balls on some power lines? – Maggie, age 8, West Chester, Pennsylvania


Have you ever looked up while driving on a highway and spotted those big orange balls hanging on power lines? They look a bit like giant toy beads strung along the electric wires.

What in the world are those overgrown basketballs doing up there?

I’m a professor who teaches about and researches power systems, the big networks that move electricity from power plants to our homes, schools and businesses.

Those big orange balls don’t help with electricity flow or improve the efficiency of the power lines, but they do have a very important job. Officially called aviation marker balls or spherical markers, they’re there to help pilots see power lines so airplanes and helicopters don’t crash into them. They’re like bright warning signs in the sky, protecting pilots, passengers and people on the ground below.

Big round warning signs in the sky

Power lines can be very hard to see from an airplane or helicopter, especially when pilots are flying low. Thin metal wires can visually blend into the background of nature.

The orange balls help the lines stand out. You can think of them as being like reflective tape on a bike – just a little something simple that helps people notice a danger before it’s too late.

Orange isn’t a random choice. This vibrant color is very visible to the human eye and especially stands out against the more muted colors of nature – blue sky, green trees or gray clouds. Sometimes the balls are red or white, or even striped, but orange is the most common because it works well in most lighting conditions.

Aviation safety rules in many countries explain which colors should be used so pilots can quickly recognize hazards. Organizations like the U.S. Federal Aviation Administration publish guidelines you can check out about marking obstacles near flight paths.

These balls may look like slightly oversized ping-pong balls from your perspective on the ground. But most are actually much bigger, about the size of a large beach ball, roughly 2 to 3 feet (0.6 to 1 meter) across. Each one can weigh 10 to 25 pounds (4.5 to 11 kilograms), about as heavy as a large backpack full of books.

They’re usually made from strong plastic or fiberglass, similar to materials used in boats or playground equipment. That way, they can survive years of sun, rain, snow, wind – and even the occasional bird landing on them.

Even though they sit on wires that carry huge amounts of electricity, the balls themselves are not energized. They’re made of insulating materials, so electricity does not flow through them.

Why are there so many wires up there?

High-voltage power lines are like highways for electric power, carrying electricity from the power plants where it is generated to the places where it is used.

The wires are strung between sturdy metal towers or wooden poles that are very tall to keep dangerous high-voltage electric wires high up in the sky, far away from people on the ground. This design makes it safe to walk, play and drive underneath them. Some transmission towers, especially for very high-voltage lines, can be as tall as a 15-story building.

If you look closely at big transmission lines, you’ll often see three thick wires, sometimes with an additional thinner one on top that’s called a shield wire. Because the shield wire sits higher, lightning is more likely to hit it first, protecting the other wires from a strong blast of electricity that can damage equipment or cause power outages. The shield wire is connected to the ground, so a lightning strike’s electricity can flow safely down the tower and into the earth.

The three main wires work together to carry electricity in a steady rhythm. By sharing the job among three wires instead of one, the system can move more energy with less waste, making it more efficient.

Clamping the balls to the wires

Installing the aviation marker balls is a job for specially trained crews, often working from helicopters. The power line usually stays turned on while the work is being done, so safety rules and careful planning are critical. The ball comes in two halves that clamp around the wire and bolt together tightly.

Once installed, these balls can last 10 to 15 years, depending on weather and conditions. They don’t need much maintenance, but utilities inspect them from time to time to make sure they haven’t cracked or faded too much.

Not every transmission line needs the markers. Usually only places where aircraft are more likely to fly low – such as near rivers, valleys, airports or helicopter routes – will use these brightly colored balls. Most neighborhood power lines are too low to need markers.

Next time you spot those bright orange dots in the sky, you’ll know: They’re not electrical equipment, and their color isn’t random. They’re simple, clever tools helping keep our busy world a little safer.

From PCOS to PMOS: What the name change to polyendocrine metabolic ovarian syndrome means for women’s health

Source: The Conversation – Canada – By Pauline McDonagh Hull, PhD Candidate, Department of Community Health Sciences, Cumming School of Medicine, University of Calgary

“Hopeful,” “excited” and “helpful” for the future of women’s health — these are just some of the words expressed by the team that worked together for more than a decade to change the name polycystic ovary syndrome (PCOS) to polyendocrine metabolic ovarian syndrome (PMOS).

PMOS is a chronic condition associated with diabetes, heart disease, depression, infertility, pregnancy complications and a general decreased quality of life. It affects an estimated one in eight women worldwide, and about one in 10 Canadian women, yet the World Health Organization estimates that 70 per cent of those affected have never received a diagnosis.

Why the name has changed

The term PCOS was inaccurate, because there is no increase in abnormal ovarian cysts. Rather, the hallmark of this condition is follicles, or little fluid sacs, around partly developed eggs, which are caused when development is disrupted by a hormonal or chemical messenger disturbance.

For years, this inaccuracy contributed to the disorder being misunderstood, underrecognized, underdiagnosed and undertreated. Because PMOS is not primarily a disease of the ovaries, calling it PCOS meant all the broader features of the condition were neglected.

In a news release from Monash University, in Melbourne, Australia,
, chair of the charity Verity in the United Kingdom and a member of the name change team with almost 20 years’ lived PMOS experience, explains:

“It has not only impacted how the condition has been understood, it has also affected how seriously it is taken. The inaccurate name has negatively influenced awareness, education, and even the level of research, attention and funding it has received.”

The new name, PMOS, published in The Lancet on May 12, reflects the broader polyendocrine disturbances occurring in women’s insulin, androgens and neuroendocrine and ovarian hormones, and the metabolic impacts these have on their lives.

Prof. Helena Teede, the endocrinologist at Monash University who led the international name change team, said in an announcement: “PMOS is building on what we knew before but really is reflective of the much more diverse and broad features of this condition.”

The name change team also wants the new name to help remove the significant stigma and judgment that is often associated with PMOS, including stigma and judgment around weight gain. Anxiety, depression and eating disorders are all common in women with PMOS, and the risk of metabolic complications like developing Type 2 diabetes is high and occurs at a younger age compared to women without PMOS. Many women are also affected by bothersome symptoms like acne and excess hair growth.

With the new name now reflecting the condition as a complex and cyclical metabolic disorder, Robyn Vettese, who is chair of the PMOS Patient Advisory Council in Alberta and co-author on this story, hopes this will mean all patients, whose symptoms can vary significantly, are met with the understanding they deserve and are supported for long-term health.

How the name was changed

The transition from PCOS to PMOS has been described as the largest, unprecedented global engagement process ever undertaken for a health condition name change and highlights the value of creating space for patients’ voices and lived experiences in improving health care.

Following years of advocacy and campaigning, in 2025, the name change team reported on a survey that found 85.6 per cent of patients and 76.1 per cent of health professionals agreed with the change.

This secured the mandate needed, and after 22,000 health professionals and people living with PMOS participated in surveys and workshops — together with the involvement of 56 leading academic, clinical and patient organizations, including the Canadian Society of Endocrinology and Metabolism and the Society of Obstetricians and Gynaecologists of Canada — the acronym PCOS was retired.

Future PMOS advocacy and research

Looking ahead, Vettese sees the name change as a call to action for care providers to participate in education and learning about PMOS and to promote a wider, whole-body health approach.

Dr. Jamie Benham, who runs the Endocrine, Metabolic and Reproductive Advancements (EMBRACE) Women’s Health Research Lab at the University of Calgary and is an author of this story, agrees. She is one of the 62 Global Name Change Consortium authors cited in The Lancet paper, and her immediate priorities are to raise awareness about what the PMOS change means and to continue collaborating with patients to ensure the lab’s research questions are directly relevant to the affected population.

Increasing diagnosis and providing funding for PMOS learning and research in Canada are critical to improve treatment and management of this lifelong, challenging condition, as was underscored in the 2024 McKinsey Health Institute report, Closing the Women’s Health Gap.

Throughout the three-year transition period planned for the name change, we anticipate an expansion in PMOS care by Canadian physicians in the diverse fields of endocrinology, gynecology, dermatology, pediatrics and primary practice.

Up until now, the treatment and management of PMOS has been insufficient. Its new name, and the journey to achieve it, signifies real, genuine change. Researchers, clinicians and patients have come together to say that people with PMOS deserve more appropriate and comprehensive care and support, throughout their whole lives. They are very hopeful this will happen.
