Starmer has enabled the far-right – promises of ‘progressive patriotism’ are no longer enough

Faced with an insurgent UK far right backed by a billionaire oligarch, Prime Minister Keir Starmer’s pledge to lead the progressive fightback is long overdue. If Starmer’s speech, however, is to be anything but empty rhetoric, he must abandon his failed strategy of chasing the Reform vote in favour of a bolder, more hopeful narrative.

Based on his government’s actions and discourse so far, the signs are far from promising. He has helped embolden the very politics he claims to oppose.

Starmer’s speech comes hot on the heels of Britain’s largest ever far-right mobilisation. Between 110,000 and 150,000 people descended on London for the so-called “Unite The Kingdom” march, organised by Stephen Yaxley-Lennon (better known as Tommy Robinson).

In line with far-right great replacement theory, the principal target of those speaking at the event was Islam and immigration – but there were plenty of examples of placards targeting other marginalised groups such as LGBTQ+ people.

Appearing via video link, the billionaire oligarch Elon Musk warned of the need “to fight back or die” in the face of “massive uncontrolled migration”. Starmer’s home secretary, Shabana Mahmood labelled Musk’s words as abhorrent and Starmer said some of the views expressed at the rally did not reflect a “nation proudly built on tolerance, diversity and respect”. The government, however, arguably shares significant responsibility for legitimising the politics behind the rally.

Starmer’s denunciation of “loutish behaviour” mimics his decision to attribute the summer 2024 riots to “far-right thuggery”. Countering far-right figures such as Yaxley-Lennon is vitally important. However, on its own, such reactive discourse is not enough. Associating far-right ideas with the margins of society ignores the way in which so-called mainstream politicians have normalised such politics .

The Unite the Kingdom march was the climax of “operation raise the colours”, which saw people all over the country putting up flags wherever they felt like doing so. Bearing all the hallmarks of a carefully coordinated “astroturf” campaign (stimulating grassroots support for a cause and then using that support to legitimise other activities), raise the colours contributed to an emboldening of the far right.

Further to “just” raising the union flag and St George’s cross, there were acts of vandalism against mosques and ethnic food restaurants as well as racist graffiti. It is hard not to also see the link between those putting up flags in the streets and those waving them outside so-called “asylum hotels”.

Most of this has since been condemned by Starmer, yet he initially embraced raise the colours wholeheartedly, even calling himself a “big supporter of flags”. Meanwhile, the (at the time) home secretary Yvette Cooper made the somewhat bizarre assertion that her entire home was bedecked with St George’s crosses and Union Jacks and said that people should “put ‘em up anywhere”.

The violent rhetoric and actions on display at the rally reveal the severe limitations of this attempt to co-opt the flag waving initiative to attract its backers.

I would argue this also illustrates how Starmer’s attempt to pivot towards a more “progressive” form of patriotism is doomed to fail. Because patriotism is so often tied to exclusion and the policing of national boundaries, it ultimately undermines broader commitments to empathy, equality and solidarity.

A losing game

In the longer term, Starmer’s own policies since taking office have tried to outflank Reform on the right. Starmer has framed Reform as Labour’s official opposition. In line with this, the Labour party has made immigration, and Channel boat crossings in particular, one of its top priorities.

On taking office, Labour’s prioritisation of “secure borders” has been encapsulated by the violent slogan of “smash the criminal gangs”. Starmer has accused past Conservative governments of running an “open-borders experiment” and has allowed images of deportations to be made public – a technique most notoriously used in the Trump administration’s racially charged deportation videos that are shared with the public in the knowledge that they will be widely circulated on social media.

Starmer cannot defeat the far right by using its language and tactics. This much is evident not only in the chants and placards which target him at far-right rallies, but also his disastrous polling figures.

In the words of journalist Nesrine Malik, “we need new stories” when addressing the socioeconomic and sociopolitical challenges facing the UK. A key example is the way we talk about immigration. It is telling that just 5% of overall migration to the UK is classified as illegal yet it almost entirely dominates the national conversation.

Starmer has done nothing to counter that imbalance. Indeed, his speech, intended to mark a fightback of progressive values, has doubled-down on anti-migrant rhetoric.

In particular, the introduction of digital ID cards is framed as a way of ensuring Britain takes back control of its borders. Claiming Britain has been “squeamish” about talking about illegal immigration, Starmer has said ID cards would help protect working people’s wages against those who “slip into the shadow economy and remain here illegally”.

Academic research consistently illustrates that the way in which immigration is framed by politicians and the media has a significant impact on how and whether people view it as a “legitimate concern”. It is incumbent on a supposedly “social democrat” prime minister to lead this change in narrative.

Starmer’s intervention on the side of progressive values might be a welcome one, were it not premised on a dead duck narrative of “progressive patriotism”. It is, though, effectively meaningless if he continues to lead a government which oversees and manages the “division” he ostensibly seeks to address.

Why Charli XCX might be Gen Z’s answer to the Romantic poets

Source: The Conversation – UK – By Katie MacLean, PhD Student, University of Stirling

Popstar Charli XCX is turning her hand to acting in the new film Erupcja. In it, she recites Lord Byron’s poem Darkness. Charli and Byron may be 200 years apart, but the legacies of Romantic poetry are alive in Brat, the singer’s sixth studio album.

Byron has often been described as the first modern celebrity, notorious in regency England for rumours of incest, homosexuality and vampirism. Irish writer Marguerite Gardiner, Countess of Blessington, wrote in 1823 that “Byron had so unquenchable a thirst for celebrity, that no means were left untried that might attain it.”

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


Brat is similarly concerned with the self-construction of identity and celebrity in Charli’s “party girl” image. Her interest in fame is reflected both in her album’s extensive branding and in lyrics like, “When I go to the club I wanna hear those club classics/I wanna dance to me”.

In Might say Something Stupid, Charli admits that she is “famous but not quite” and doesn’t know if she “belong[s] here anymore”. This echoes John Keats’ 1818 poem When I have fears that I may cease to be, in which he laments that he might die before he experiences true literary achievement and fame. Charli has inherited the identity of lonely artist obsessed with creative genius from the Romantics.

Anxieties around legacy resurface in Apple. Charli uses the apple as a Gothic metaphor for inheritance and cursed fate, not unlike Byron’s On Leaving Newstead Abbey, in which he imagines his ancestors haunting him until death. Romantic poetry is full of this tension between inheritance and decay, and Charli’s lyrics show how those anxieties still haunt us today.

Romantic poets were obsessed with the archaic and classical through Greek and Roman mythology, ruins, and medievalism, like John Keats’ poem Ode to a Grecian Urn. Similarly, Brat frequently looks back with references to Y2K aesthetics and early 2000s culture.

Charli romanticises nostalgia in the song Rewind:

Used to burn CDs full of songs I didn’t know
Used to sit in my bedroom, puttin’ polish on my toe
Recently, I’ve been thinkin’ ‘bout a way simpler time
Sometimes, I really think it would be cool to rewind.

In both cases, romantic nostalgia becomes a creative lens to explore our relationship with the past.

Romantic poets were fascinated by the sublime, characterised as the overwhelming power of nature. In Wordsworth’s Lines Composed A Few Miles Above Tintern Abbey, he contrasts “the din/Of towns and cities” against awe-inspiring “steep and lofty cliffs”.

How to resolve friendship tension like Lorde and Charli XCX


In the song, Everything is Romantic, Charli instead finds beauty in juxtaposing symbols: the man-made (“Bad tattoos on leather tan skin/Jesus Christ on a Plastic sign”) contrasts nature (“Lemons on thе trees and on the ground/[…] Pompeii in the distance”). Where the Romantics rejected the artificial, Charli embraces it, extending Romantic ideas into the 21st century.

The most explicitly romantic song on Brat is So I, an elegy for the producer Sophie, who died suddenly in 2020. Just as in romantic elegies, Charli laments the loss of genius: “Your star burns so bright/ […] You had a power like a lightnin’ strike”.

Percy Shelley’s elegy Adonais, written on the death of Keats, concludes that the genius of Keats lives on through his poetry. Similarly, Charli sings: “Your sounds, your words live on, endless.” The influence of Romantic elegies can still be seen in popular culture through music, particularly songs which immortalise fellow artists and explore contemporary understandings of grief.

The media studies academic David Tetzlaff argues that, “Romanticism remains the common language of middle-class rebelliousness.” Brat rebels most obviously in its neon green branding, hyperpop tracks and aggressive autotune, becoming one of Rolling Stone’s 250 greatest albums of the 21st century so far. So, Brat Summer’ may been a neon green Tik-Tok trend, but the album perfectly showcases how Romanticism influences art and culture today.

As Matt Sangster, an expert in 18th-century literature and material culture, writes in David Bowie and the Legacies of Romanticism, “[t]he ways that texts happened in the past are hugely important, but texts and the idea clusters they spawn are also fascinating for the complex ways that they continue to happen in our lives.” Concerns inherited from the Romantics are evident in Brat, with its exploration of celebrity, nostalgia, nature, legacy and loss. Romanticism isn’t stuck in the 19th century – it is alive today in the very places you may least expect.

Calling in the animal drug detectives − helping veterinarians help beluga whales, goats and all creatures big and small

Source: The Conversation – USA – By Sherry Cox, Clinical Professor of Biomedical and Diagnostic Sciences, University of Tennessee

How do you measure the concentration of a drug in a tortoise shell? Thirawatana Phaisalratana/iStock via Getty Images Plus

In my work as a veterinary pharmacologist, I never know exactly what I’m going to get when I open my email. It could be a request from a veterinarian asking my team to determine the concentration of a drug to treat the shell of a turtle infected with fungal disease. Or it could be an inquiry from a researcher wondering whether we can help them figure out the dose of antacid they should give goats and sheep with ulcers.

In one email, a veterinarian wanted to know whether we could determine the concentration of an extended-release antibiotic in tigers to determine how to best treat them. Figuring this out would make the difference between trying to give a sick tiger a pill every 12 hours – a difficult task – or a shot once a month.

At our veterinary pharmacology lab, my colleagues and I analyze drug levels in animals from zoos and aquariums nationwide, from tiny mice to majestic elephants and from penguins to farm animals. Whether it’s a dolphin with an infection or a tiger in pain, we help veterinarians determine the right treatment, including how much medicine is best for each animal.

Here’s a peek behind the scenes to experience a day in the life of a veterinary pharmacologist, and what it takes to ensure these creatures get the care they need to thrive.

Beluga milk and antibiotics

One day, I received an email from an aquarium asking whether my team and I could determine the concentration of an antibiotic in milk – specifically beluga whale milk.

Beluga whales live in cold waters throughout the Arctic and are extremely sociable mammals that hunt and migrate together in pods. They are recognized for their distinctive white color and are known as the “canaries of the sea” for the wide variety of sounds they make. Whales like the beluga are at the top of the food chain and play an important role in the overall health of the marine environment. However, these animals are threatened by extinction. There are roughly 150,000 beluga whales left in the world today, and certain populations are considered endangered.

The aquarium reached out to us as part of their research on the factors threatening the sustainability of belugas in the wild and what steps can be taken to protect them. The team there works with animals both in human care and in their natural habitats to improve husbandry methods, understanding of the underwater world and the conservation of aquatic life.

We agreed to try to extract the drug from the milk. However, we first needed a sample of whale’s milk. So, the first question: How do you get milk from a whale? Through my decades of working in this field, my team has studied samples from a wide range of species, but this was the first time someone asked us to analyze whale’s milk.

Unfortunately, I never did find out how they actually got the sample. But I cannot imagine it was easy. The sample we received reminded us of a thick buttermilk, very clumpy with a little bit of a blue tint.

The milk sample they gave us came from a whale with an infection who was also nursing a calf. The veterinarians wanted to know whether the antibiotic was crossing into the milk, indicating that the calf may have been exposed to the drug.

Each chemical compound requires its own unique process to extract from a particular sample type. This extraction can range from one to 15 steps and can take from one to six hours to perform. After we devised a method and procedure to extract the antibiotic from milk, we set to analyzing the sample.

We found the presence of drug in the sample, which meant the nursing calf was getting exposed to antibiotic from its mother’s milk. This posed health risks to the calf, including disruption to its gut microbiome that could lead to a weakened immune system, increased susceptibility to infections and antibiotic resistance.

Making a treatment plan

Now that the aquarium knew the beluga milk contained the antibiotic, it could devise a treatment plan. Beluga calves are dependent on nursing for the first year of life until their teeth emerge. So stopping the calf from drinking its mother’s milk wasn’t an option.

When prescribing antibiotics, a veterinarian needs to carefully consider the potential risks and benefits to both the nursing mother and her offspring. The goal is to provide effective treatment for the parent while minimizing the risk of harm to the offspring.

In order to determine whether the nursing calf was at risk, the veterinarian wanted to determine the concentration of antibiotic in the calf.

To measure how much antibiotic the calf was ingesting from the milk, the aquarium sent us a plasma sample from the calf to analyze. While we did find measurable amounts of the drug in the sample, there was not enough to cause harm to the calf.

With this information, the veterinarian decided to continue to give the mother the antibiotic. The veterinarian gave our team samples from both the mother and the calf to continue monitoring the drug concentrations.

Effectively treating animals

For many animals, there is limited information available to guide clinicians when deciding treatment plans. Many dosage regimens are extrapolated from animals with different physiologies and metabolisms compared to the animal receiving the drug. What might cure one species might kill another.

Evaluating how safe and effective a drug is for a particular species is essential to not only properly treat and prevent disease but also to relieve pain. The research we do provides needed information on appropriate doses in vulnerable species for which there is no scientific data available.

I find the work we do rewarding because we provide information to so many veterinarians to help them take care of remarkable creatures great and small.

Could your urine predict your dementia risk?

Source: The Conversation – UK – By Hong Xu, Assistant Professor at Division of Clinical Geriatrics, Karolinska Institutet

A simple urine test could reveal your risk of developing dementia decades before symptoms appear, a new study shows. For the study, my colleagues and I tracked 130,000 people and found that protein in the urine may act as an early warning sign for memory problems.

Our research showed that people with higher levels of protein leaking into their urine – a condition known as albuminuria – had a significantly greater chance of developing dementia. The association was strongest for vascular dementia, the second most common form after Alzheimer’s, and mixed dementia, which combines features of both types.

Crucially, this connection held true regardless of how well participants’ kidneys were functioning overall. In other words, protein in urine appears to predict dementia risk independently, even when standard kidney tests appear normal.

Our findings highlight how closely the kidneys and brain are connected. Both rely on networks of tiny, delicate blood vessels to function properly. When these vessels are damaged – by high blood pressure, diabetes, or other factors – the same damage that causes protein to leak into urine can also reduce blood flow to the brain.

Your kidneys act like filters, keeping useful proteins in your blood while filtering out waste. When those filters are damaged, albumin protein starts leaking through.

The brain has its own protective barrier – the blood-brain barrier – made of tightly packed cells that prevent harmful substances from entering brain tissue. Just as damaged kidney filters become leaky, a compromised blood-brain barrier allows toxins and inflammatory molecules to pass through, potentially triggering the brain changes that lead to dementia.

This discovery opens exciting possibilities for prevention. Several medications already used to protect kidneys may also protect memory. Ace inhibitors and Arbs, blood pressure drugs that reduce protein leakage, could potentially do double duty for brain health.

Even newer drugs show promise. GLP-1 drugs such as semaglutide (better known as Ozempic) and SGLT2 inhibitors such as dapagliflozin were originally developed for diabetes but also reduce protein in urine. Whether they prevent dementia remains to be proved, but early signs are encouraging.

While we cannot yet prove that treating kidney problems will prevent dementia – that would require following participants for decades in controlled trials – the biological pathway makes sense, particularly given how blood vessel damage affects both organs.

An ounce of prevention

So when should you start caring about this? Vascular damage accumulates over years, so earlier intervention is better. For most people, focusing on kidney and heart health from middle age onwards is sensible, especially if you have diabetes, high blood pressure, kidney disease, obesity, or a family history of these conditions.

Currently, doctors mainly test urine protein in people with diabetes or high blood pressure. But our findings raise questions about whether everyone over 50 should be screened, particularly those with multiple risk factors. That is a public health question requiring more research and policy discussion.

The good news is that you do not need to wait for new guidelines to take action. Lifestyle changes that protect kidneys also benefit the brain. Quitting smoking, controlling blood pressure and blood sugar, eating a balanced diet and exercising regularly can reduce your risk of both kidney disease and dementia.

Poor sleep may nudge the brain toward dementia, researchers find


If confirmed by future studies, urine protein testing could become a standard part of dementia risk assessments. It is cheap, non-invasive and can be performed with simple dipstick tests in any doctor’s office.

While there is still no cure for dementia, early detection and prevention remain our best tools. By recognising that protein in urine signals more than just kidney trouble, we may be able to identify and protect those at risk long before memory problems begin. Sometimes the most important clues about your brain’s future health are found in the most unlikely places.

Sauna competitions have gone from dangerous endurance to therapeutic showmanship

Source: The Conversation – UK – By Daniel Brayson, Lecturer, Life Sciences, University of Westminster

When the British Sauna Society promises “multisensory theatre and dazzling skills” at the national Aufguss championships, you might wonder what on earth they’re talking about. The German word Aufguss means “infusion”, but don’t let that fool you into thinking this is some gentle aromatherapy session.

The idea of a sauna “championship” is likely to conjure visions of stubborn people engaging in dangerous endurance contests. Thankfully, Aufguss is nothing like that. Instead, it’s more akin to figure skating than speed skating – a choreographed performance where infusion masters compete to create the most immersive sauna experience.

These Aufguss meisters combine carefully selected essential oils, which they aerosolise on hot stones, with music and light shows while skilfully manipulating the steam using towels and body movements.

Their ten-to-20-minute performances are judged on professionalism, heat distribution, waving techniques, fragrance usage, theme implementation, atmosphere and team spirit – yes, audience participation is expected.

But is this theatrical sweating actually good for you? The health benefits are surprisingly substantial. Sauna use is a form of passive heat therapy that typically involves multiple sessions of five to 20 minutes followed by cooling activities. Studies often report reduced blood pressure and lower cardiovascular disease risk, along with decreased inflammation throughout the body.

The reason lies in how repeated heat exposure challenges our cardiovascular system in a similar way exercise does. When we’re exposed to extreme temperatures, our bodies redistribute blood from core organs to the extremities, such as the arms and legs, where the increased surface area helps dissipate heat more effectively. Blood vessels in our skin dilate to bring heat closer to the surface, while our hearts work harder to pump blood around this expanded network.

There’s even evidence that regular sauna use prepares us for our warming planet. Heat acclimatisation increases blood volume, creating a sweat reserve we can access at lower core temperatures, promoting better cooling through evaporation – a handy adaptation given the inevitable increase in heatwaves we’ll face, thanks to the climate crisis.

The aromatherapy element adds another layer of benefit. While often dismissed as fringe medicine, there’s growing evidence that essential oils like lavender can be beneficial for mental health by reducing depression and anxiety. Music, too, has demonstrable mood-altering effects, with certain frequencies shown to reduce blood pressure and slow heart and breathing rates.

However, nature gives with one hand and takes with the other. Recent research shows that while heat exposure makes us resilient, it also accelerates biological ageing. Still, this seems a reasonable trade-off compared to the alternative.

UK Aufguss championship 2023.

Old-school sauna championships were less salubrious

The alternative, sadly, was demonstrated at the old competitive sauna world championships. Unlike today’s artistic Aufguss competitions, these events tested pure endurance – whoever stayed longest without collapsing won. This dangerous format inevitably ended in tragedy when a finalist died and another nearly perished at the 2010 championships. Unsurprisingly, it was the last time such an event was held.

The difference is crucial. Our bodies constantly generate heat through metabolism, and in normal temperatures we lose it through radiation, conduction, convection and evaporation.

In extreme heat, most of these mechanisms become ineffective, except evaporation – hence, sweating becomes critical. Curiously, one rule of the old endurance competitions forbade wiping sweat away, essentially sabotaging the body’s primary cooling method.

When heat exposure continues beyond our cooling capacity, core temperature rises above 40°C. Here, the body is on a point of no return as heat generated by metabolism increases. The chemical reactions keeping our cells alive begin breaking down, leading to organ failure and ultimately death.

Which brings us back to the choice between two very different types of competitive sauna. One celebrates skill, artistry and the therapeutic benefits of controlled heat exposure, combined with aromatherapy and music. The other was a deadly test of stubborn endurance that rightfully belongs in the dustbin of history.

I know which type of competitive sauna I prefer.

Why scientists may be fearful of speaking out about Trump’s autism claims

Source: The Conversation – UK – By Padraig Murphy, Associate Professor in Communications, Dublin City University

“Are you making good health decisions?” reads one Robert F. Kennedy Jr. meme on social media, a slogan printed against an image of a smiling US health secretary. Such social media posts invariably invite lively comments beneath them, but the situation is deadly serious.

On 22 September, Donald Trump and RFK Jr. publicly proposed a link between paracetamol – commonly referred to in the US by the brand name Tylenol – and autism. The paracetamol link has also been shown, through rigorous research, to be false.

It’s far from the first falsehood about science to be presented at the highest levels of the US government. While RFK Jr. denies being anti-vaccination, he has repeatedly stated debunked claims about supposed vaccine harm.

The highly politicised nature of such claims and the current political environment may lead to a reluctance among some scientists to speak out publicly. But it’s imperative that they continue to defend science in the public arena.

With wall-to-wall coverage of such issues, it is easy for the considered views of experts to get drowned out – and headlines rarely lead with the perspectives of researchers. The speed of the news cycle can also mean that the story has moved on by the time they are in a position to comment.

Science communicators weigh up the published evidence on a topic of controversy, factoring in multiple perspectives. They also talk about when science gets it wrong – and when retractions of journal articles are needed.

Toxic environment

But online toxicity and hostility on social media have increased to the extent that both scientists and, indeed, science journalists have a real fear of writing about topics even where they have strong expertise. And with the US government making major cuts to research funding and targeting politicised areas such as climate science in particular, some may be inclined to stay quiet or self-censor to avoid losing their grants.

We’ve also seen government scientists removed from their positions by the Trump administration. In June 2025, RFK Jr. removed all 17 members of a committee that issues official government recommendations on immunisations.

In August 2025, the director of the US Centres for Disease Control and Prevention, Susan Monarez, was fired for what she says was refusing to dismiss vaccine policy officials. The health secretary says it was because he didn’t trust her.

Political decisions such as these and others can have a chilling effect on scientists and the media, where commentators may feel the need to tread carefully. Yet this makes it all the more urgent that everyone involved in communicating science to the public ups their game and defend expertise.

Nevertheless, when the politics are combined with the toxicity of debate in the public sphere, particularly on social media, it can make conveying expert opinions very challenging. Science communicators have often developed valuable and thoughtful methods to put the message across to the public.

Platforms like Bluesky, which give users greater control over their interactions, have been one such attempt for a civil space to discuss science. Yet, on other platforms, it is easy to see how valuable efforts such as these could sour amid the kinds of vitriolic attacks come from anonymous sources who seem to act with impunity online.

There is arguably a place to fight fire with fire, including with the use of ridicule. Examples include California governor Gavin Newsom’s mockery of Trump tweets or South Park satirising the US administration in the basest of fashions.

The longer-term goals in controlling false scientific statements involve increasing media literacy, prebunking– debunking myths and conspiracy theories before they spread rapidly – and setting out “nudge” effects, where there are several choices offered to people that eventual lead to a change of behaviour, as happens in advertising.

If a scientific or innovation programme has the resources, subvertising techniques – where spoofs and parodies of corporate ads are created to critique their messages – have been used effectively against the tobacco lobby and oil companies.

It may help for professional bodies, universities and other institutions involved in communicating science to maintain vigilance on contentious claims so that they are well prepared when these topics blow up in the media. The tylenol-autism claim is not something that had been widely shared in mainstream publications before now. But science communicators should be ready for the next time it comes up.

Andy Burnham’s leadership ambitions: what is the path to mounting a challenge against Keir Starmer?

Source: The Conversation – UK – By Thomas Caygill, Senior Lecturer in Politics, Nottingham Trent University

Manchester mayor Andy Burnham has triggered a blazing row by telling the Telegraph that MPs want him to mount a leadership challenge against prime minister Keir Starmer.

Starmer’s poll ratings are dire and for some weeks, discussion within some sections of the Labour Party has turned to who is his most likely successor.

Up until early September, the assumption was that it would be Angela Rayner. But her resignation as deputy prime minister and deputy leader of the party over a financial scandal has made that less certain. Attention therefore turned to Burnham.

Burnham is popular within the party – and has been for a long time. A poll of party members conducted by Survation back in June for the website LabourList placed him just above Rayner as the top choice to be the next leader. He is also seen as plain-spoken and direct – a quality that Nigel Farage also has but which Starmer lacks.

However, he does face several hurdles if he does wish to become the leader of the labour party one day, whether through Starmer’s resignation or some other turn of events.

The first challenge is that you must be a Labour MP to stand for the leadership of the party – and Burnham is not an MP. For Burnham to become an MP before the next general election (expected in 2029), there will need to be a vacancy (ideally in his home region, Manchester) and currently there isn’t one. There have been suggestions that a sitting MP in Manchester could stand down triggering a by-election that Burnham could stand in, although none of those MPs currently seem keen.

Burnham would also then need to be shortlisted as a candidate for the seat, which will require approval from the national executive committee (NEC). Starmer currently has a majority on that committee. Given that Burnham is a former MP and the mayor of Greater Manchester, it would be odd if the NEC were to block him, but in theory it is possible. He would then need to win the shortlisting vote in the constituency Labour party where he stood. Again, I would imagine if he was standing in a Manchester seat, that the local party would approve him, but it is a further hurdle nonetheless.

The next hurdle is the need to win the by-election. While Manchester is a Labour stronghold and remains so, given the support for Reform UK in the polls, victory is not guaranteed. Parties can pour resources into by-elections as there is only one vote taking place (as opposed to 650 taking place on the same day in general elections) so activists can be bussed in and campaign finance is not so thin on the ground. You can guarantee that Reform UK will throw the kitchen sink at any by-election where they have a chance of victory, regardless of whether Burnham is standing or not.

If he clears all these hurdles, a further one remains. Currently to challenge Starmer for the leadership of the party, any challenger would need the backing of 80 MPs. This is a high threshold, as we have seen during the deputy leadership election and again there is no guarantee that enough MPs would back him. There has been some backlash to his criticism of Starmer and the party, particularly as the labour party annual conference approaches. Starmer’s allies (and investors) have also been quick to point out that his suggestion to borrow more to fund increased public spending would trigger a similar run on the pound that we saw during Liz Truss’ time as prime minister.

It is for these reasons that a challenge to Starmer from Burnham is unlikely at least in the short term. However, if Labour’s poll ratings do not improve over the course of the next 12 months, discussion of succession will only ramp up further.

Any challenge to Starmer’s leadership in the short term will likely come from within the parliamentary Labour party. The next key moment of danger will be after the 2026 local elections (in England) and devolved parliamentary elections (in Scotland and Wales). However, we should note that Labour is not as regicidal as the Conservative party. It has far less of a history of toppling even unpopular leaders.

Labour MPs should also remember the public’s reaction to the Conservative party going through three leaders in the last parliament – it did play a part in their defeat last year.

Before 2013, divers on North America’s west coast rarely saw purple sea urchins. The spiky animals, which are voracious kelp eaters,- were a favorite food of the coast’s iconic sunflower sea stars. The giant sea stars, recognizable for their many arms, kept the urchin population in check, with the help of sea otters, lobsters and some large fishes.

That balance allowed the local kelp forests to flourish, providing food and protection for young fish and other sea life.

Then, in 2013, recreational divers began noticing gruesomely dissolving sea star corpses and living sea stars that were writhing and twisting, their arms dropping and literally walking away. It was the beginning of a sea star wasting disease outbreak that would nearly wipe out all the sunflower sea stars along the coast.

Their disappearance, combined with a massive marine heat wave called “the blob,” set off a cascade of catastrophic ecological changes that turned these kelp biodiverse hot spots into vast sea urchin barrens, devoid of almost any other species.

This disaster also encouraged human innovation, however. The result has brought an unexpected boost for the local fisheries and restaurants through the development of a new culinary delight, and questions about how best to help kelp forests, and the US$500 billion in economic value they provide, recover for the future.

Losing sea stars disrupted an entire ecosystem

I am the director of the Marine Science Institute in Santa Barbara, California, one of the areas severely hit by the loss of sea stars.

From sea star wasting disease, more than 90% of the sunflower sea stars died along the entirety of North America’s west coast, from Baja to Alaska. In only the first five years of the outbreak, sea star wasting disease become one of the largest epidemics to hit a marine species. By 2017, sunflower sea stars, Pycnopodia helianthoide, were rarely found south of Washington state.

For over a decade, the cause of the devastation was a mystery, until recently, when my colleagues traced sea star wasting disease to a highly infectious vibrio bacteria. Today, sea star wasting disease has spread widely, even as far as Antarctica.

As sea stars disappeared, the purple sea urchin population exploded, increasing an astonishing 10,000% from 2014 to 2022.

The urchins ate through kelp forests. The resulting loss of kelp canopy and the understory foliage below it reverberated across the whole ecosystem, affecting the tiniest of zooplankton and giants like gray whales, all of which are linked in the complex kelp forest food web of who eats who.

Ecological cascades – a succession of changes across an ecosystem when habitats are disturbed – can occur when critical populations disappear or change in other significant ways.

Removing the kelp alters light levels below, leading to changes such as turf algae growth in place of filter-feeding invertebrates such as clams and scallops. Turf algae also make it harder for kelp to regrow, exacerbating the problem.

The loss of kelp also resulted in fewer mysids, a zooplankton that relies on kelp for habitat and which makes up a majority of gray whales’ diets. Thus, as urchin populations went up and kelp disappeared, gray whales also had less food.

How California learned to embrace the urchin

The loss of sunflower sea stars to wasting disease has not only altered the kelp ecosystem, but it has also altered the landscape of Pacific fisheries, potentially forever.

When I started research on purple sea urchins in 2001, there were not enough specimens in the whole of the Monterey Bay for me to collect and use for my studies. In fact, I had to order my animals from an East Coast distributor.

Mostly there were red sea urchins, Strongylocentrotus fransiscanus, highly prized for their large and delicious gonads and sold as “uni” to American and Asian markets.

But with the recent purple sea urchin boom, Strongylocentrotus purpuratus, a new and unexpected market on the west coast has blossomed – taking these kelp killers out of the sea and onto plates in restaurants around America.

This pivot from reds to purple urchins by fishers and the aquaculture industry took time and creativity. Purple sea urchins tend to be small and lack the rich gonads that make the reds so profitable. To adjust their flavor, texture and size, innovators turned to harvesting these animals from the sea by hand and then moving them to land-based facilities – called “urchin ranches” – where they fatten up by eating seaweeds.

The results have been remarkable. In Santa Barbara, a thriving industry now raises these animals for the culinary market, where the artisanal urchins go for $8 to $10 a pop. In one example, an abalone aquaculture program used its expertise and facility to profit from this new abundance.

Innovative ways to solve kelp decline

You might be asking yourself if we can just eat our way out of this crisis.

It’s not a new idea. The invasion of Pacific lionfish into Florida coasts, the Gulf of Mexico and parts of the Caribbean was slowed down by local divers and recreational fishing groups teaming up to hunt and then market lionfish to restaurants.

It is unlikely that purple sea urchin ranching will make much of a dent in the population, but numerous projects are currently aimed at both recovering kelp forests and keeping the monetary benefits of the urchin boom flowing to the local economy simultaneously. The ingenuity to flip a bad outcome into a productive local aquaculture industry has been so popular that even state agencies are now funding local innovators to expand purple urchin ranching, assisting both the local environment and the local economy.

Scientists, state agencies and conservation groups are working on sunflower sea star restoration efforts and kelp recovery programs, and are considering other ways to reduce the urchin population.

One option is to increase otter populations in places like Northern California and Oregon, where they were once abundant. Otters can eat upward of 10,000 urchins per year. But the approach is controversial in Southern California. A similar conservation effort failed before, and there are concerns about the effects a bigger otter population would have on local fisheries, including the now-depleted black abalone.

So where do we go from here?

As the world’s appetite for farmed seafood has expanded, groups like Urchinomics and their investors are using this edible calamity to promote kelp restoration, create jobs and boost local economies.

In a way, sea star wasting disease and the precipitous kelp declines inadvertently created a mutually beneficial alignment of conservation, local artisanal fishing and land-based aquaculture.

In the long term, additional marine heat waves, like the one occurring in 2025, and their associated marine diseases and subsequent habitat losses, require global actions to reduce climate change. Future outbreaks like sea star wasting disease are almost certain to emerge.

Yet, it has also been found that some of the harms of urchin population growth can be lessened when sections of ocean are protected. For example, in some California marine protected areas where urchin predator diversity was high, the impacts of sea star wasting disease and its ecological cascade were reduced. In other words, in areas where there was limited fishing, as sea star numbers dropped, the urchin population was at least partially kept in check by those legally protected predators.

This finding suggests that along with global carbon reductions, local conservation and human innovations – like those bringing purple uni to our plates – can help prevent some ecological cascades that harm our increasingly threatened marine resources.

Why aren’t companies speeding up investment? A new theory offers an answer to an economic paradox

Source: The Conversation – USA (2) – By David Ikenberry, Professor of Finance, Leeds School of Business, University of Colorado Boulder

For years, I’ve puzzled over a question that seems to defy common sense: If stock markets are hitting records and tech innovation seems endless, why aren’t companies pouring money back into new projects?

Yes, they’re still investing – but the pace of business spending is slower than you’d expect, especially outside of AI.

And if you’ve noticed headlines about sluggish business spending even as corporate profits soar, you’re not alone. It’s a puzzle that’s confounded economists, policymakers and investors for decades. Back in 1975, U.S. public companies reinvested an average of 25 cents for every dollar on their balance sheets. Today, that figure is closer to 12 cents.

In other words, corporate America is flush with cash, but it’s surprisingly stingy about reinvesting in its own future. What happened?

I’m an economist, and my colleague Gustavo Grullon and I recently published a study in the Journal of Finance that turns the field’s conventional wisdom on its head. Our research suggests the issue isn’t cautious executives or jittery markets – it’s about how economists have historically measured companies’ incentives to invest in the first place.

Asking the wrong Q

For decades, economists have relied on a simple but appealing ratio – Tobin’s Q, named after the famous economist James Tobin – to gauge whether companies should ramp up investment.

They calculate this by dividing a company’s market value – what it would take to purchase the firm outright with cash – by its replacement value, or how much it would cost to rebuild the company from scratch. The result is called “Q.” The higher the Q, the theory goes, the more incentive executives have to invest.

But reality hasn’t conformed to fit the theory. Over the past half-century, Tobin’s Q has gone up, yet investment rates have gone down sharply.

Why the disconnect? Our research points to one key culprit: excess capacity. Many U.S. companies already have more factories, machines or service capability than they can use. By not correcting for this issue, the traditional Tobin’s Q will overstate the incentive that companies have to grow.

To see this, consider a commercial real estate company that owns a portfolio of office buildings. In recent years, with the rise of e-commerce and remote work, many of their properties have been running well below capacity. Now suppose a few new tenants start paying rent and begin absorbing a portion of that empty space. Stock prices will rise in response to seeing these new cash flows, which in turn will lead Q to rise.

Traditionally, this increase in Q would suggest that it’s a good time to invest in new buildings – but the reality is quite different with idle capacity still in the system. Why pour money into building another office tower if existing ones still have empty floors?

This key idea is that what matters isn’t the average value of all assets – it’s the marginal value of adding one more dollar of investment. And because capacity utilization has been steadily eroding over the past half-century, many firms see little reason to invest.

That last point may come as a surprise, but the U.S. economy, with all its factories and offices, isn’t nearly as abuzz with activity as it was after, say, World War II. Today, many sectors operate well below full throttle. This growing slack in the system over time helps explain why companies have pulled back on their rate of investment, even as profits and market values climb.

Why has capacity utilization fallen so much over the past half-century? It’s not entirely clear, but what economists call “structural economic rigidities” – things such as regulatory hurdles, labor market frictions or shifts in cost structure – seem to be part of the answer. These factors can drag businesses into a state of chronic underuse, especially after recessions.

Why it matters

This isn’t just an academic debate. The implications are profound, whether you closely follow Wall Street or just enjoy armchair economic policy debates. For one thing, this dynamic might help explain why tax cuts haven’t spurred investment the way supporters have hoped.

Take the 2017 Tax Cuts and Jobs Act, which slashed the top corporate tax rate from 35% to 21% and introduced full expensing for equipment investments. Supporters promised a wave of new investment.

But when my colleague and I looked at the numbers, we found the opposite. In the four years before the tax cuts, publicly traded U.S. firms had an aggregate investment rate, including intangibles, of 13.9%. In the four years after the tax cut, the average investment rate fell to 12.4% – in other words, no evidence of a bump.

Where did those liberated cash flows go? Instead of plowing this newfound cash after the tax cuts into new projects, many companies funneled it into stock buybacks and dividends.

In retrospect, this makes sense. If a company has excess capacity, the incentive to invest should be more muted, even if new machines are suddenly cheaper thanks to tax breaks. If the demand isn’t there, why buy them?

Even with the most generous tax incentives, the core challenge remains: You can’t force-feed investment into an economy already swimming in excess capacity. If companies don’t see real, scalable demand, tax breaks alone aren’t likely to unlock a new era of business spending.

That doesn’t mean tax policy doesn’t matter – it does, especially for smaller firms with real growth prospects. But for the large, well-established firms that make up the lion’s share of the economy, the bigger challenge is demand. Rather than trying to stimulate even more investment, policymakers should prioritize understanding why demand is sagging relative to supply and reducing economic rigidities where they can. That way, the capacity generated by new investment has somewhere useful to go.

Charlie Kirk and the making of an AI-generated martyr

When prominent political or cultural figures die in the U.S., the remembrance of their life often veers into hagiography. And that’s what’s been happening since the gruesome killing of conservative activist and Turning Point USA co-founder Charlie Kirk.

The word hagiography comes from the Christian tradition of writing about saints’ lives, but the practice often spills into secular politics and media, falling under the umbrella of what’s called, in sociology, the “sacralization of politics.” Assassinations and violent deaths, in particular, tend to be interpreted in sacred terms: The person becomes a secular martyr who made a heroic sacrifice. They are portrayed as morally righteous and spiritually pure.

This is, to some degree, a natural part of mourning. But taking a closer look at why this happens – and how the internet accelerates it – offers some important insights into politics in the U.S. today.

From presidents to protest leaders

The construction of Ronald Reagan’s postpresidential image is a prime example of this process.

After his presidency, Republican leaders steadily polished his memory into a symbol of conservative triumph, downplaying scandals such as Iran-Contra or Reagan’s early skepticism of civil rights. Today, Reagan is remembered less as a complex politician and more as a saint of free markets and patriotism.

Among liberals, Martin Luther King Jr. experienced a comparable transformation, though it took a different form. King’s critiques of capitalism, militarism and structural racism are often downplayed in most mainstream remembrances, leaving behind a softer image of peaceful dreamer. The annual holiday, scores of street renamings and public murals honor him, but they also tame his legacy into a universally palatable story of unity.

Even more contested figures such as John F. Kennedy or Abraham Lincoln show the same pattern. Their assassinations were followed by waves of mourning that elevated them into near-mythic status.

Decades after Kennedy’s death, his portrait hung in the homes of many American Catholics, often adjacent to religious iconography such as Virgin Mary statuettes. Lincoln, meanwhile, became a kind of civic saint: His memorial in Washington, D.C., looks like a temple, with words from his speeches etched into the walls.

Why it happens and what it means

The hagiography of public figures serves several purposes. It taps into deep human needs, helping grieving communities manage loss by providing moral clarity in the face of chaos.

It also allows political movements to consolidate power by sanctifying their leaders and discouraging dissent. And it reassures followers that their cause is righteous – even cosmic.

In a polarized environment, the elevation of a figure into a saint does more than honor the individual. It turns a political struggle into a sacred one. If you see someone as a martyr, then opposition to their movement is not merely disagreement, it is desecration. In this sense, hagiography is not simply about remembering the dead: It mobilizes the living.

But there are risks. Once someone is framed as a saint, criticism becomes taboo. The more sacralized a figure, the harder it becomes to discuss their flaws, mistakes or controversial actions. Hagiography flattens history and narrows democratic debate.

After Queen Elizabeth II’s death in 2022, for example, public mourning in the U.K. and abroad quickly elevated her legacy into a symbol of stability and continuity, with mass tributes, viral imagery and global ceremonies transforming a complex reign into a simplified story of devotion and service.

It also fuels polarization. If one side’s leader is a martyr, then the other side must be villainous. The framing is simple but powerful.

In Kirk’s case, many of his supporters described him as a truth seeker whose death underscored a deeper moral message. At Kirk’s memorial service in Arizona, President Donald Trump called him a “martyr for American freedom.” On social media, Turning Point USA and Kirk’s official X account described him as “America’s greatest martyr to free speech.”

In doing so, they elevated his death as symbolic of larger battles over censorship. By emphasizing the fact that he died while simply speaking, they also reinforced the idea that liberals and the left are more likely to resort to violence to silence their ideological enemies, even as evidence shows otherwise.

The digital supercharge

Treating public figures like saints is not new, but the speed and scale of the process is. Over the past two decades, social media has turned hagiography from a slow cultural drift into a rapid-fire production cycle.

Memes, livestreams and hashtags now allow anyone to canonize someone they admire. When NBA Hall-of-Famer Kobe Bryant died in 2020, social media was flooded within hours with devotional images, murals and video compilations that cast him as more than an athlete: He became a spiritual icon of perseverance.

Similarly, after Ruth Bader Ginsburg’s death, the “Notorious RBG” meme ecosystem instantly expanded to include digital portraits and merchandise that cast her as a saintly defender of justice.

The same dynamics surrounded Charlie Kirk. Within hours of his assassination, memes appeared of Kirk draped in an American flag, being carried by Jesus.

In the days after his death, AI-generated audio clips of Kirk styled as “sermons” began circulating online, while supporters shared Bible verses that they claimed matched the exact timing of his passing. Together, these acts cast his death in religious terms: It wasn’t just a political assassination – it was a moment of spiritual significance.

Such clips and verses spread effortlessly across social media, where narratives about public figures can solidify within hours, often before facts are confirmed, leaving little room for nuance or investigation.

Easy-to-create memes and videos also enable ordinary users to participate in a sacralization process, making it more of a grassroots effort than something that’s imposed from the top down.

In other words, digital culture transforms what was once the slow work of monuments and textbooks into a living, flexible folk religion of culture and politics.

Toward clearer politics

Hagiography will not disappear. It meets emotional and political needs too effectively. But acknowledging its patterns helps citizens and journalists resist its distortions. The task is not to deny grief or admiration but to preserve space for nuance and accountability.

In the U.S., where religion, culture and politics frequently intertwine, recognizing that sainthood in politics is always constructed – and often strategic – can better allow people to honor loss without letting mythmaking dictate the terms of public life.
