It’s often said that Donald Trump’s power base in the Maga movement has contributed to the radicalisation of the Republican party. Political scientists worry about the implications of this for the future of American democracy itself.

One example of that radicalisation was the attack on the US Capitol on January 6 2021 in an attempt to overturn the result. Exacerbating that radicalisation is the movement’s hostility towards much of the mainstream media. This is something that has been amplified by the US president himself, who has famously referred to the media as “the enemy of the American people”.

But how has this radical movement movement emerged from the socially conservative Republican Party? The rise of Maga has marked an important political shift in America that has many liberal-minded people scratching their heads. Psychology studies can offer insights that can help explain the Maga movement’s motivations.

1. Fused identity

Identity is central to understanding the way Maga holds together as a group and can also explain many of its motives. Trump has been able to mobilise his base effectively by communicating that shared identity. And it’s this sense of common identity and purpose that has been so important in the development of Maga as a powerful political movement.

The almost absolute faith in Trump’s leadership has a lot to do with negative resentment of other groups that he singles out for criticism, particularly migrants, liberals and feminists. But it is actually a positive identification with white nationalism that is a stronger indicator of the sort of person who might identify with Maga.

Maga supporters unite around a shared perception of threat to their status, often related to issues of race and immigration. But it is also seen to be motivated by the desire to cultivate belonging and group pride as a way to regain lost esteem.

Some researchers also believe that even the act of wearing a Maga hat is a sign of what is known as “identity fusion” – when boundaries between the self and the group blur. When this occurs, wearing a Maga hat may be a symbol of who I am rather than just who I voted for.

This is significant since identity fusion is associated with reported willingness to undertake more extreme actions such as hurting people and damaging property to uphold the Trump community and to achieve his aims.

2. Moral self-righteousness

Maga members also tend to adhere to the idea that one’s own ethnic group is more morally pure than others. Maga ideology tends to divide America into “good” and “evil” groups, with themselves as good and out-groups, such as the ones mentioned above, cast as evil. This positions “true Americans”, the people who built the nation, patriots who have “had enough”, as part of the former.

Since it frames politics as a struggle over “right values and lifestyles”, such rhetoric heightens the risk of malignant moral superiority. When communicated by a leader, it creates in followers the sense that they have an obligation to act against these “evil” forces which threaten their group.

When this sense of superiority is threatened, it can lead to aggression, such as the assault on the US Capitol .

3. The right to dominate other groups

Aggressiveness in political groups such as Maga is also connected to what is known as “social dominance orientation”. This relates to belief in a hierarchy – the idea that one social group has the right to dominate other groups.

Research shows people who believe in hierarchy are more likely to disregard basic democratic principles. They see society as a “competitive jungle” where groups struggle for power and dominance.

As a result, they view groups that differ from them as inferior. This justifies any actions that maintain their in-group status.

This holds true even if – as in the case of Maga-followers – it means a belief in violence in response to unwelcome social and cultural changes. Polling has found that Maga supporters are also far more likely to believe that there will be a civil war in the US and that violence in order to advance the movement’s political objectives would be justified.

4. Aggressive followership

There’s a scientific debate about what draws people to authoritarian leaders. Some scholars emphasise the tendency to want to submit to authority, high levels of aggression when sanctioned and adherence to conventional values such as traditional views on religion and sexuality. Others focus more on a preference for conformity over personal autonomy.

But they agree on one point: authoritarian followers submit to leaders who stress the superiority of their social group and who they consider to be capable of handling the threats they see as coming from other groups.

Research on the Maga movement from 2016 shows that Trump supporters were more likely than other supporters of other Republican party candidates to score high on one facet of authoritarianism: the willingness to resort to aggression towards people seen to go against social norms if encouraged by someone they’ve accepted as an authority figure. But they don’t appear to score as highly on two other facets: submission to established authorities and an adherence to conventional values.

This suggests that authoritarianism among the Maga movement has evolved into a more distinct profile, characterised primarily by a prejudiced aggressiveness towards other social groups.

History tells us that radical political movements tend to pop up when the societal context is perceived as threatening. In this process, some people have personal dispositions that make them more prone to follow authoritarian leaders. So it’s important to take both personality and context into account when trying to understand movements such as Maga.

Humans have moved plants and animals well beyond their native ranges, across barriers that normally prevent dispersal. As a result, people have increased the rates of hybridisation between populations that were once isolated for thousands, or even millions, of years.

Animal hybrids are a controversial issue among scientists, as they often suffer from health issues.

But our new study of Australian dingoes, published in the journal PNAS, found that hybridisation with introduced European dogs might have had evolutionary benefits.

New species can evolve when a subset of the population becomes separated, often by physical barriers like mountains or oceans. Over time, these isolated populations accumulate unique genetic mutations, some of which become fixed. If these populations spend long enough apart, they become so different they can no longer interbreed.

Although they were once domestic, dingoes became isolated from other dogs around 3,500 years ago and evolved into free-living apex predators. Some scientists argue that the dingoes’ distinct appearance and behaviour warrant their recognition as a new species. Others claim that hybridisation with domestic dogs, which were brought to the continent by Europeans from the late-18th century onwards, has blurred this boundary.

Humans have been moving animals around for millennia. When farmers spread from the Near East into Europe around 8,500 years ago, for example, the domestic pigs that accompanied them came into contact and mated with European wild boar. In some cases where there were no closely related native populations, however, such as the import of exotic animals during the Roman period, escapees formed feral populations. Dingoes fit into this second category.

Species translocations and hybridisation accelerated during the colonial period, which reshaped local ecosystems. Hybrid offspring can lose the unique traits that allowed their parent populations to thrive in their specific habitats. Other effects are invisible, and can only be teased out of genetic studies.

For instance, across Asia, diversity in wild red jungle fowl populations is being lost through interbreeding with domestic chickens. In the Americas, almost all traces of Indigenous dog diversity was wiped out through hybridisation with introduced European dogs.

Hybridisation can also be beneficial. The acquisition of alleles (a different version of a gene) from another population may improve an animal’s survival in new environments, or make them resistant to new diseases.

The ancestors of modern human populations on the Tibetan Plateau, for example, inherited an allele of the EPAS1 gene from Denisovans (a closely related human species) that improved their ability to live at high altitudes.

The dingo debate

Since dingoes were only isolated from other dog populations for a few thousand years, it is not a surprise that they can readily interbreed. The “purity” of dingoes is therefore a great source of conflict between conservationists, farmers and policy makers, and is used by both sides to justify policies to either protect or persecute dingoes.

Some genetic studies have suggested that dingo-dog hybridisation has not taken place, while others indicate most dingo populations have some level of European dog ancestry. A fundamental issue with these studies is that they require comparison against a “pure” reference population. Given centuries of overlap between dingoes and dogs, it is almost impossible to be sure that modern populations do not have mixed ancestry.

To circumvent this issue, our study sequenced genomes from ancient dingo bones recovered from caves on the Nullarbor Plain in southern Australia. Crucially, this included dingoes that lived and died prior to the arrival of the First Fleet in 1788. Establishing a precolonial baseline of ancestry for dingoes allowed us to to pinpoint the degree of European dog ancestry in dingo populations across Australia today.

Our genetic analysis showed that most dingoes living in the northwest of Australia did not have any detectable European dog ancestry. The opposite was true in the southeast, where almost a quarter of the genome of some dingoes came from European dogs.

Further investigation found that the European ancestry was in fact broken up into small chunks throughout the genome of dingoes, indicating that interbreeding took place at least ten generations (or 30 years) ago.

In fact, most of the hybrid mating coincided with the outset of aerial baiting programs in the mid-20th century, when poisoned meat was dropped from helicopters to kill dingoes en masse. This reinforces similar findings in Scottish wildcats, which shows local populations were resistant to interbreeding with invasive (domestic cat) populations until their own numbers declined to the point where finding a suitable mate (another wildcat) became too difficult.

Diversity is the key to success

Superficially, gene flow between dingoes and European dogs sounds like a negative outcome. Our research, however, suggests that dingoes have actually benefited. Hybridisation has led to an increase in genetic diversity in dingoes across southeast Australia, potentially offsetting the negative effects of inbreeding.

We also found evidence that a few alleles, which were transmitted from dogs to dingoes via interbreeding, may provide better protection against infectious diseases brought to the continent by European dogs.

Despite being an introduced species, dingoes are now adapted to Australia’s varied ecosystems. Based on our results, we suggest that instead of prioritising “purity”, future conservation efforts should focus on maintaining large enough populations for natural selection to operate effectively, so that dingoes can maintain their position as Australia’s apex predator.

Hybrids are becoming increasingly common as humans and their domesticates continue to encroach into wild habitats, from Scottish salmon to Andean alpacas. In order to understand the impacts, both positive and negative, of this hybridisation, our results suggest we must first look to the past.

“Pink goes good with green.” This is a lesson we learned from Glinda (Ariana Grande) in Wicked part one. But do you remember the line that comes after that?
“Goes well with green.”

A small, easily missed comment from the green-skinned outsider Elphaba (Cynthia Erivo), but one that reveals something important about language and common usage. Hierarchies of “correct” and “incorrect” language are not just found in grammar books and classrooms, but in popular culture too.

From “holding space” to “sex cardigans”, Wicked continues to dominate popular culture, but one thing that has been overlooked is Elphaba’s insistence on correct language.

In the first film, we see Elphaba ostracised and eventually positioned as public enemy number one by the Oz propaganda machine. From the film’s very opening, a flashforward to citizens celebrating Elphaba’s death, her unpopularity is made clear in the song No One Mourns The Wicked.

One way in which the filmmakers signal Elphaba’s unlikeability is through her often awkward, borderline rude social encounters, including when she first meets her frenemy, Glinda. It’s safe to say that the two characters don’t hit it off and Elphaba’s correction seems to upset Glinda.

Glinda: I could care less what others think.

Elphaba: Couldn’t.

Glinda: What?

Elphaba: You couldn’t care less what other people think. Though, I … I doubt that.

In the land of Oz, where people “pronuncify” and “rejocify”, are “disgusticified” and “moodified”, Elphaba’s comments demonstrate the idea that there is only one correct way to use language and that incorrect language should be corrected.

From stage to cinema

Elphaba’s corrections are not in the original stage musical. They were added to the film. The adaptation of a stage show for film offers an opportunity to modernise and change parts of the story that have been controversial or become outdated.

One excellent example of this in Wicked is its improvement of the stage show’s depiction of disability. The addition of language policing, however, is more disappointing. Because when we correct someone’s language, it’s about much more than the words themselves.

Correcting language is not neutral. When we place value on using language correctly, those who fall short often find themselves judged and discriminated against.

The policing of correct language can be seen as a gatekeeping tool, deciding who belongs and who is excluded. This has inevitable consequences for diversity. The way we speak, write and sign can reflect many aspects of our identities: where and how we grew up, our gender, age and race.

Rules and rebellion

With the run time of the films almost doubling that of the stage show, there is much more time devoted to character development in the films. Elphaba’s language pedantry has been added to demonstrate how she can rub people up the wrong way. However, it also suggests an adherence to authority and to socially constructed rules that stands in contrast to her character more broadly.

Elphaba is an outsider who starts the film wanting to be “degreenified”, but by the end of Wicked part one and as a main storyline in Wicked: For Good, she is willing to sacrifice her safety and reputation to do what is morally right, rather than what is socially acceptable.

Adherence to the strict rules of correct language suggests the opposite: a tendency to want to be accepted and to uphold the societal status quo. Elphaba resists social norms in every other respect, yet the film makes her a standard grammar enforcer.

Given that this trait is absent from part two, rather than undermining her personality as a resister, perhaps this further signals Elphaba’s journey from wishing to fit in to fully embracing her outsider status. Indeed, Elphaba’s insistence on correctness speaks to a broader challenge facing anyone positioned as an outsider: having to work that much harder to be accepted.

Glinda’s (famous) need to be popular and her interests in social climbing align with traits of a language enforcer, yet her behaviour tells a different story. She corrects language only once and it concerns her original name, Galinda. When Dr Dillamond, a professor at Shiz University – who also happens to be a goat – struggles to pronounce the “gah” in Galinda, Glinda corrects his pronunciation and berates him.

This moment, present in both the stage musical and the film, does not reflect a desire to uphold the prescriptive rules of the language, but rather a personal motivation. Glinda’s name is central to her self-image and public persona, and protecting that matters to her.

Beyond Oz

In an era when equality, diversity and inclusion initiatives are being rolled back, and languages other than English face renewed marginalisation, Wicked offers a case study in how linguistic hierarchies operate under the radar of popular culture. But there are plenty other examples. Think about Ross in Friends, Ted in How I Met Your Mother and Sheldon in The Big Bang Theory – all notorious language correctors.

Elphaba’s corrections are more than just a shorthand to signal an abrasive character. They reflect the linguistic hierarchies and gatekeeping that exist beyond Oz. Using language “correctly” is a marker of belonging and shows adherence to societal norms.

Across the two films, Elphaba moves from wanting to conform and erase a stigmatised part of her identity, her skin colour, towards rebellion against convention. It’s clear she questions blind adherence to political power, but perhaps this extends further to questioning the rules we construct around language.

The ballrooms of Jane Austen’s Britain have been hailed in literature and period dramas as a marriage market where young men and women could meet and mingle. The ballroom set the scene for Elizabeth Bennet and Mr Darcy’s first encounter at Meryton’s assembly rooms in Pride and Prejudice (1813), and where Catherine Moreland and Henry Tilney bantered in Bath in Northanger Abbey (1817).

Austen herself frequented balls in Basingstoke and Southampton. The ballroom was the place to see and be seen, the focal point for socialising during “the season”. The season took place during the winter months and involved a concentrated period of public entertainments like balls, concerts and card assemblies (in which guests met to play card games).

Ball-goers needed months to prepare for these events. This included ordering gloves and shoes, and buying new gowns or dressing up old ones. Austen deliberately kept her china crepe dress from being seen before the next ball, observing that the ballroom “was a place where you would be judged”.

Ladies and gentlemen also needed to polish their dance steps. From an early age, they were instructed in how to dance, bow and curtsy, walk and greet people of differing ranks. Mastering these basics of deportment was essential, as they would be scrutinised in the ballroom.

While in Bath in 1740, Elizabeth Robinson (future leader of the 18th-century English women’s intellectual circle the Bluestockings) observed that the education of another woman was lacking, writing: “[as] for her Curtsey where she got that I cannot guess, but I will venture to say, not from the Dancing School”.

This article is part of a series commemorating the 250th anniversary of Jane Austen’s birth. Despite having published only six books, she is one of the best-known authors in history. These articles explore the legacy and life of this incredible writer.

In Northanger Abbey, Catherine Moreland’s first ball at the Upper Rooms in Bath is filled with anxiety, as: “The season was full, the room crowded, and the two ladies squeezed in as well as they could. As for Mr Allen, he repaired directly to the card-room, and left them to enjoy a mob by themselves.”

To quell the “mob”, the ballroom was managed by a master of ceremonies, who had the role of facilitating introductions, enforcing the rules and mediating disputes.

Balls opened with the minuet (a French social dance) performed by one couple at a time. A well-danced minuet was a source of pride for genteel society, as some revelled in exhibiting their accomplishments. But it was also a source of anxiety.

When a young woman named Eliza Smith married the Austens’ wealthy neighbour William Chute in 1793, she was so nervous about dancing that her mother wrote: “I am glad for your Sake there are no Minuets at Basingstoke, I know the terror you have in dancing not that you have any occasion for such fears.”

Assessing dance skill was central to the experience of the ballroom, making it even more important for dancers to try to put their best foot forward. Sixteen-year-old Elizabeth Canning (cousin of the prime minister George Canning) wrote to her mother from Bath in December 1792 that: “I was very much entertained with the bad minuet-dancers, especially with a Mr Badcock who was obliged to stand up with seven, or eight Ladies successively, to the great diversion of the Spectators.”

After the minuets, country dances filled the evening, with a column of men standing opposite their female partners. Relieved the minuets were over, Miss Canning wrote: “At last the Country dances began, there was great humming, & hawing whether or no I should dance … & I declared … that I should like to dance if I could get some mighty smart partner.”

Young ladies recorded triumphant lists of dance partners, and, indeed, Austen recalled dancing with Stephen Terry, T. Chute, James Digweed and Catherine Bigg one evening, observing: “There was a scarcity of men in general, and a still greater scarcity of any that were good for much … There was commonly a couple of ladies standing up together, but not often any so amiable as ourselves.”

For the most part, men were expected to ask women to dance with them. According to dance manuals by Thomas Wilson and G.M.S. Chivers, the ballroom occasionally saw two women or two men dancing together.

While it is assumed that it was the lady’s prerogative to accept or decline invitations to dance, she could not afford to refuse an offer unless she had no intention to dance at all “and consequently may be considered no lady”. In Pride and Prejudice, though Elizabeth Bennet would prefer not to dance with Mr Collins at the Netherfield Ball, refusing him would mean losing the opportunity to dance altogether.

However, Austen herself found a way of skirting around these rules at the Kempshott ball. Writing to her sister Cassandra in 1798 she explained that: “One of my gayest actions was sitting down two dances in preference to having Lord Bolton’s eldest son for my partner, who danced too ill to be endured.” Austen was an excellent dancer herself, proudly proclaiming that she could dance 20 dances in an evening “without any fatigue”.

Balls at the assembly rooms lasted for about five hours until precisely 11 or 12am, when, upon a signal from the master of ceremonies, the dancing concluded, even in the middle of a dance. Grudgingly, the dancers changed their dance pumps for sturdier shoes and donned their cloaks, with sedan chairs and carriages ready to whisk them home to their lodgings by the light of the moon.

The right to trial by jury dates back to at least the 12th century. The government’s proposals to limit it in England and Wales, many argue, run counter to the UK’s core democratic principles. And as others have pointed out, scrapping jury trials for some crimes is unlikely to solve the massive backlog in the crown courts.

Our research suggests that there is another reason why it is a bad idea to scrap jury trials. They can play a vital role in reducing racial discrimination in the criminal justice system.

The proposals laid out by justice secretary David Lammy would have a disproportionately negative impact on people of colour – both defendants and victims – for whom jury trials give a glimmer of hope in a criminal justice system where “ethnic minorities (excluding white minorities) appear to be over-represented”.

Government data repeatedly shows black, Asian and minority ethnic defendants are less likely to plead guilty than white defendants, and more likely to take their cases to trial. Lammy’s own 2017 review of racial inequality in the justice system suggests this is driven by a perception that the plea-bargaining process is unfair to defendants of colour, and that only a jury of peers will give them a fair trial.

Once black defendants choose a jury trial, research shows they are “more likely … to obtain acquittals or reductions in charges as a result”, compared to black defendants who plead guilty without opting for a trial.

A jury of 12 people brings a broader array of diverse perspectives and opinions which enhance the quality of discussions in deliberations, particularly in cases involving an ethnic minority defendant. Defendants should have their fate decided by people who might better understand their experiences, backgrounds and motivations.

Lammy’s 2017 review emphasised the importance of juries in making the criminal justice system more legitimate, particularly for people of colour: “Juries deliberate as a group through open discussion. This both deters and exposes prejudice or unintended bias: judgements must be justified to others.”

Sentencing is also disproportionate for defendants of colour when compared to white defendants, following both jury trials and plea agreements. Research has found that explicit or implicit judicial biases – whether judges stereotype the defendant, how they interpret sentencing recommendations from prosecutors and defence counsel, or how they apply aggravating and mitigating factors – may all contribute to these disparities.

Empirical evidence from other jurisdictions shows that more diverse juries are fairer to black defendants. Indeed, studies repeatedly show that all-white juries much more readily convict black defendants. Juries with even one black member are less likely to do so.

The UK’s Contempt of Court Act limits this type of research with live juries. But there is enough evidence from other jurisdictions to suggest that retaining juries, and ensuring those juries are diverse, is essential for protecting the fair trial rights of people of colour generally, and black people in particular.

Justice for victims

Jury trials are also essential for black victims and their families. Since 2022, we have worked with the family and friends of Dea-John Reid, a 14-year-old black boy who was racially abused and chased through the streets of Birmingham by a group of white boys and men who fatally stabbed him in broad daylight.

In their 2022 trial, the perpetrators were acquitted of racially aggravated murder, with only the principal offender found guilty of manslaughter by a jury of one Asian and 11 white members. Dea-John’s family felt that the lack of diversity on the jury, which did not have a single black member, could have meant they were less likely to see Dea-John as a worthy victim. Research shows that black men and boys are stereotyped as suspects – even when they are victims of crime.

Since 2022, we have worked with the family’s campaign, which supports retaining jury trials, but wants them to be more ethnically diverse, particularly in cases involving black victims. Our research has documented the campaign and is addressing critical gaps in UK research on jury diversity.

Diversity in the judiciary

Lammy’s proposals for reform include expanding the use of bench trials. This means that more cases would be heard by a single judge alone.

The judiciary in England and Wales is neither sufficiently diverse nor representative of the population. While black, Asian or minority ethnic people make up around 22% of the population, as of 2025, they make up only 11% of all court judges.

Lammy’s proposal also goes against what the public wants. In 2024, we surveyed 1,000 members of the public, 75% of whom stated explicitly that they believed the UK should have jury trials.

While most of our respondents believed that jury trials were fair (51%) and trustworthy (60%), they also felt strongly that more diverse juries were fairer (61%). Around half of people (51%) believed juries should look like the communities they serve. We found that for people of colour, taking part in jury service was viewed as even more important than for white respondents.

When it comes to perceptions of fairness and trust in the courts, we found important racial differences. Our research found that people of colour trust judges and the courts at lower rates than white people. People of colour in our survey were also more likely than white people to believe that judges treat them more unfairly compared to white people. And most of our respondents believed that more diversity in the judiciary is needed.

If Lammy remains committed to reducing inequality in the criminal justice system for people of colour, rather than reducing jury trials, he should be increasing them, and the diversity on them, to ensure justice for all.

The launch of Your Party, a new leftwing offering for British voters, was meant to embody a different kind of politics. It was to be collective and collaborative – a political movement built from the grassroots up.

At a time when trust in politicians is low and cynicism high, the idea of a new movement on the left captured imagination. Almost immediately after it was announced, 80,000 people expressed their interest in joining.

Yet the collective has, from the start, been beset with problems. Former Labour MP Zarah Sultana announced the party’s launch apparently before Jeremy Corbyn, her partner in the endeavour, was ready. A debacle over who was holding on to some £800,000 in donations led to a very public spat between the two even before the party could get on its feet.

Amid this confusion, between launching in July and holding its inaugural conference in November, Your Party has already shrunk. Those original 80,000 potential members have become 55,000 signed-up members.

Of these, 2,500 people were selected through a lottery system to attend the party conference. And as they congregated in Liverpool, it quickly became clear that it would not be plain sailing. Delegates were caught between idealism and infighting – between a genuine and urgent desire to create something new and the old factionalism that has long preoccupied the British left.

The tension was visible even before the conference began. On the eve of the event, Corbyn appeared at a poetry and music evening where he was interrupted by hecklers demanding he denounce Zionism.

For a man who has spent his political life campaigning for Palestinian rights, the moment was indicative of a key issue the party must confront: a puritanical one-upmanship. This was fringe politics, where nothing you do is quite sufficient. For all the talk of solidarity and comradeship, the left remains a space where interrogation around ideological purity is never far away.

Opening the event, councillor Lucy Williams attempted to confront the tensions head on. Everyone knew there had been loud disagreement, she said, “but I like to see our leaders fighting. I’d rather be in a movement where people care enough to argue than in a party where everyone nods along while the country collapses around them. Unity isn’t pretending that we all agree; unity is disagreeing honestly and then cracking on with it. We’re not perfect, but we’re real – and people will trust real.”

Her defence of the messiness of democracy was forceful. But for some delegates, her apparent defence of washing dirty laundry in public was read not as authenticity but as testimony that the endeavour was in descent. “Being real” in this incarnation was not an election winner.

Committed, diverse and hopeful

Attendees were young and old. Many were former Labour members. Others had never been involved in politics before. The conference was full of people deeply committed to a socialist cause: equality, equity and social justice.

But ideas about what these buzzwords meant were deeply divided. Divisions were not just about personalities and internal factions but about ingrained beliefs.

The promise of unity was quickly met with the realities of ideology. From revolutionary communists to conservative Muslims to trans-rights activists, there are uneasy alliances in Your Party’s broad church, many wanting change on their own terms. Compromise is too often viewed as weakness and a lack of commitment to the cause.

And yet, there was also hope, one young man who had left the UK after Brexit to live on the continent said he had to come back for the conference, “when your home country does something like this you just have to”.

Sultana was conspicuous by her absence during Corbyn’s opening speech. She had announced she was boycotting her own conference over what she called a “witch hunt” against members of other socialist organisations, especially those associated with the Socialist Workers Party.

Some had reportedly been barred because dual party membership was not allowed – until a vote at the conference changed the rules.

By day two, anticipation was building about whether Sultana would show. The name of the party was formally recognised and a collective leadership model agreed. Corbyn had wanted a single leader model, Sultana, who had originally wanted to be joint co-leader, had favoured a collective model (knowing a contest between her and Corbyn would be difficult to win).

And then the waiting was over, Sultana’s arrival saw delegates pack the hall. There was almost a sigh of relief. She started by calling out the party leadership, for bullying, pointing to underhand tactics “straight from the Labour right handbook”. She set out her vision for a new approach – radical, impatient and angry. This would be a united left – all socialists fighting together. She was received rapturously. Her speech ended with chants of “Oh, Zarah Sultana.”

Yet this was not a unifying moment. Corbyn was present too, extending the courtesy she did not afford him when he first spoke to conference. The two did not appear together.

His supporters were disillusioned by her public dressing down of the unelected faceless bureaucrats (or the adults in the room, as they saw themselves). The votes may have been for maximum member democracy, but Sultana was really setting out the blueprint for Sultanaism. “This isn’t going to go anywhere. Any hope I had of an alternative to what we have now, of a united left, well it’s been tanked,” one disillusioned Corbyn supporter told me.

Before leaving Liverpool, the party had at least achieved some of its formal aims. It has a name, a leadership structure and some key constitutional provisions. The broader picture, however, remains harder to read.

The excitement of participatory politics was still there, but this was a hall full, mainly, of the converted. Those who wanted a more moderate or what they see as “electable” party, were left out in the cold. They will now be hoping that the chill does not kill any potential green shoots. Or it will be the Green party who will ultimately benefit, come elections in the spring.

Imagine waking up in 2040 to unusually quiet streets. By then, an estimated 60% of vehicles worldwide could be electric, cutting air pollution and noise in cities. But the shift to cleaner transport comes with a lesser-known problem – a huge rise in mining waste.

Lithium, a vital ingredient in electric vehicle batteries, leaves behind extraordinary amounts of waste. In 2023 alone, the global battery industry generated 1.8 million tonnes of lithium-related waste, almost all of it sent to landfill.

At the same time, the construction sector faces its own environmental crisis. Concrete is the most widely used man-made material on Earth. We produce enough of it each year to build a wall around the planet twice over.

Its main ingredient, Portland cement, is responsible for nearly 8% of global carbon emissions. As demand rises, the industry is running out of cleaner alternatives.

These two challenges – booming lithium production and the carbon cost of cement – may seem unrelated. But the solution to both could be the same: turning lithium mining waste into a new kind of low-carbon cement.

A waste problem hiding in plain sight

Lithium-ion batteries have reshaped the global energy landscape since they were invented in the 1970s. Their value is expected to soar to more than US$400 billion (£302 billion) as electric vehicle sales continue to increase.

But lithium does not appear in nature as a pure metal. It must be extracted from minerals or salty brines. Most of them are in the “lithium triangle” of Chile, Argentina and Bolivia, which together hold more than 60% of the world’s reserves.

Extracting lithium is a messy business. For every tonne of battery-grade lithium carbonate produced, around nine to ten tonnes of waste are created. As countries race to meet climate targets, demand for lithium is expected to triple by 2030.

The UK government plans to develop new extraction sites in Cornwall and the northeast of England.

But this growing waste stream contains something valuable. Chemically, lithium mining waste is rich in the same compounds (silicates, alumina and calcium oxides) that help cement harden and gain strength. In other words, the waste from one green technology could help clean up another.

Our team is testing whether UK lithium mining waste can be used to replace cement in concrete.

The idea is simple. If this waste can act as a supplementary binding material, it could cut the amount of traditional cement needed. This could reduce carbon emissions by up to 50%. But proving this requires detailed scientific work.

Work is underway to analyse the microstructure, chemical behaviour and long-term durability of lithium waste-based concretes, from early lab tests to full-scale trials in real conditions. If successful, “lithicrete” could provide the UK with a way of using waste from the country’s emerging lithium industry to build low-carbon infrastructure.

For years, the concrete industry has tried to reduce its reliance on Portland cement by blending it with industrial byproducts such as fly ash and blast furnace slag. But these materials are becoming scarce as coal power plants shut down and heavy industry changes. In fact, there could be an imminent shortfall in traditional cement alternatives, threatening progress on decarbonisation.

This makes the search for new materials urgent. Lithium mining waste, available in large volumes and chemically compatible with cement, offers a promising option just as the sector faces a bottleneck.

Why this matters

The environmental stakes are high. Concrete underpins almost everything we build, from homes to hospitals, schools and bridges. Demand is only growing. Cutting emissions from clinker (the core component of cement) and using alternative binders could deliver 20% of the reductions needed for the sector to reach net zero by 2050.

If lithium mining waste could replace part of the cement used in concrete, it would help slash emissions, reduce landfill and strengthen the UK’s resilience as it moves away from imported industrial by-products. It would also mean the transition to green transport like electric cars doesn’t simply shift environmental burdens elsewhere.

We argue that the transition to cleaner technology must also be circular. Rather than allowing one part of the green transition to create problems for another, materials should be reused and designed to stay in the system for as long as possible.

Psychedelic medicine has regained momentum in 2025. Investors are coming back, regulatory attitudes are softening, trial results are improving and major pharmaceutical firms that kept their distance are starting to pay attention.

This is quite a turnaround for a sector whose share prices collapsed and whose funding dried up when weak trial results combined with rising interest rates in 2022. But enthusiasm should be tempered.

Psychedelic drugs are hard to turn into profitable medicines. Some of the strategies companies are using to overcome these obstacles could ultimately remove the elements that many people believe make them effective in mental health treatment.

My research points to three features of psychedelics that make commercial development unusually complicated.

The first challenge is intellectual property. Developing a new medicine is expensive, and investors only commit money if they think a company can recover those costs later. Patents make that possible: they grant a temporary monopoly, allowing firms to raise prices once a drug is approved.

But psychedelic compounds don’t fit comfortably with this model. Psilocybin and mescaline are natural, so companies cannot claim them as inventions.

Synthetic drugs such as LSD were created decades ago, and their original patents have expired. Many of these substances also have well-documented histories of use in Indigenous healing traditions, which makes it harder to argue that therapies based on them are genuinely new.

Firms can still patent delivery methods, formulations or small chemical tweaks. But these protections are narrow and fairly easy to challenge, so they don’t provide the kind of security investors look for.

The second challenge is practical. A psychedelic session isn’t like taking an antidepressant at home. A psychedelic trip can last six to 15 hours, so patients are prepared in advance of the session, supervised throughout and supported afterwards to help them process the experience. This requires trained staff, clinical space and time.

Health systems and insurers have not yet agreed on how to pay for this type of care, and companies have no clear model for delivering psychedelic therapy at scale. The economics of a treatment that occupies a clinic room and several professionals for most of a working day bear little resemblance to standard antidepressants.

The third challenge concerns clinical testing. Most medicines are evaluated in trials where neither participants nor researchers know who has received the real drug and who has received a placebo. With psychedelics, this becomes obvious as soon as the effects begin. Participants know when they are tripping, and researchers know too.

Some trials experiment with low doses or active placebos that cause mild sensations. But it is unclear whether regulators will treat these designs as equivalent to the gold-standard trials used for conventional medicines. This uncertainty makes it harder for investors to see a clear path to regulatory approval.

Two directions

In response to these challenges, the field is developing in two directions. One route is to develop short-duration compounds like 5-MeO-DMT, which produce a very intense altered state that lasts minutes rather than hours.

A session of that length is easier to supervise, demands fewer clinical resources and does not tie up a treatment room for most of the day. Companies pursuing this strategy have encouraging early results and have attracted renewed investment.

But safety remains an issue: delivering such a powerful psychedelic can be overwhelming, especially when therapeutic support is limited. As one researcher warned, “you don’t want to advance the world’s most powerful psychedelic experience on the timescale of a dental cleaning”.

The other route goes further. Instead of compressing the trip, some companies are trying to remove it altogether with so-called neuroplastogens. These molecules are designed to trigger the brain changes associated with classic psychedelics without the trip.

Because these compounds are new, they offer the intellectual property protection investors look for. They also avoid the unpredictable experiences that make psychedelic sessions difficult to deliver in clinics and are more compatible with the insurance and regulatory systems of conventional medicines.

However, the science behind them is still young, and it is not yet clear whether drugs without the trip can provide the same benefits that drew attention to these compounds in the first place.

Both approaches seek to make psychedelics easier to administer, insure and patent, but they also push the experience itself to the margins.

Many patients credit the psychedelic trip with their progress in therapy. Biotech companies see it as an obstacle to profitability. If that patient view is right, commercialised psychedelic medicine may never become the mental health revolution that companies and their investors expect.

When Cyclone Ditwah made landfall on November 28 2025, Sri Lanka experienced one of its deadliest environmental disasters in modern history.

President Anura Kumara Dissanayake declared it the “largest and most challenging natural disaster in our history”. Torrential rains triggered widespread floods and landslides, leading to more than 350 confirmed deaths, hundreds missing and over 1.4 million people affected nationwide.

Major road and rail systems were cut off, hydropower stations and water treatment plants failed, and thousands of families were forced into emergency shelters. Reservoirs overflowed, riverbanks collapsed and communities near the Mahaweli, Kelani, Malwathu Oya and Mundeni Aru river basins were inundated within hours.

These were not random failures. They were systemic. Many of the regions that flooded were vulnerable areas adjacent to coastal lagoons and low-lying river plains. Cyclone Ditwah was not an anomaly. It exposed the underlying fragilities of Sri Lanka’s existing flood-management and drainage infrastructure.

This follows on from the devastating tropical cyclone in 1978 and the Boxing Day 2004 tsunami disaster. Fifty years ago, flood infrastructure was not in a good state. Significant improvements haven’t been made since then, mainly due to poor urban planning.

Between 2018 and 2022, I worked with a global team of coastal engineers, social scientists and policy makers from academia and government organisations in the UK, Australia and Sri Lanka. Our research project focused on producing a new generation of compound flood hazard maps, based on computer modelling that considers all the storm surge components (surge, tide and sea level rise) and the rainfall effect.

I led the hydrological modelling efforts for Sri Lanka – focusing on how tropical-cyclone rainfall and storm surge combine to generate destructive flooding patterns for three vulnerable cities: Batticaloa, Mullaitivu and Mannar. The team worked with Sri Lanka’s Coast Conservation and Coastal Resource Management Department (CCD) to address a critical question: How do storm surges from tropical cyclones interact with rainfall to produce extreme inland and coastal floods?

Through analysis of historic cyclone tracks, we showed that Sri Lanka lies at the convergence of multiple storm pathways in the Bay of Bengal. This is why the country repeatedly suffers not only from rainfall-driven inundation but also from saltwater intrusion driven deep inland through lagoons and estuaries.

My team and I developed the hydrologic model for Batticaloa, using the Mundeni Aru river basin as a pilot case. We combined rainfall data, digital terrain maps (that indicate trees, buildings, roads and bare land) and river-flow simulations to identify the most vulnerable communities depending on the topography. Low-lying settlements adjacent to the Batticaloa and Valachchenai lagoons were particularly vulnerable to tropical cyclone-induced flooding.

Similar modelling work was proposed for Mullaitivu and Mannar, both historic cyclone-landfall regions. However, COVID disrupted much of the planned in-country engagement, in-depth modelling and translation of findings into policy tools, creating a serious lag between scientific insights and what planning authorities are currently referencing.

Ditwah’s aftermath – breached embankments, power failures, displaced families, submerged neighbourhoods – corresponds almost exactly to the worst-case compound-flood scenarios shown by our data. These are not purely meteorological phenomena. They depend on the flow of water and land-based infrastructure.

Drainage networks still rely on outdated historical rainfall records. Coastal defences are built for storm surges of previous decades. Urban development continues to occupy natural flood buffers such as wetlands and lagoon edges. Vulnerability has become physically engineered into the landscape.

Proactive planning

Working with government agencies including the CCD, the Met Office and the Disaster Management Centre, Sri Lanka can proactively integrate compound-flood science into planning and disaster risk-reduction strategies.

This includes producing updated flood maps that capture rainfall, river flow, storm surge and sea-level-rise dynamics. Hydrological models can be translated into operational tools for national and municipal planning authorities.

Drainage and river-management systems (such as seasonal removal of sand and debris) can be redesigned with the future (not historical) rainfall intensities in mind. Improving early-warning systems involves incorporating multiple hazards and long-range scenario modelling can be embedded into disaster-preparedness and land-use planning.

These measures enable policymakers, engineers and local administrations to make evidence-based decisions that reflect accelerating climate-driven risks rather than obsolete assumptions.

Cyclone Ditwah should mark a turning point. With the right integration of science, planning and governance, disasters of this magnitude need not become inevitable hallmarks of Sri Lanka’s future. And by aligning infrastructure and policy with the real hydrological dynamics of our changing climate, governments can better protect people, environment and economy from the storms yet to come.

Kimchi has been enjoyed for centuries in Korea. But the spicy fermented cabbage dish has recently gained popularity in other parts of the world not only because of its delicious taste, but because of its potential to positively influence the many thousands of important microbes living in our gut as well as our overall health.

A recent study suggests that kimchi may also help support the immune system.

The study looked at 13 overweight adults over a 12-week period. Participants were randomly assigned to three groups. One group received a placebo, while the other two groups received two different types of kimchi powder (kimchi that had been freeze dried and put into a capsule).

The first type of kimchi powder was naturally fermented using microbes already in the environment. The second type was fermented with a chosen bacterial culture instead of relying on natural microbes. The amount of kimchi powder participants were given daily was roughly equivalent to eating 30 grams of fresh kimchi.

Blood samples were taken before and after the study and analysed using a technique that shows what each immune cell is doing instead of giving an overall average. This gives a detailed view of how the immune system responded.

The study found that kimchi affected the immune system in a targeted way. It increased the activity of antigen-presenting cells (APCs). These are immune cells that ingest pathogens, process them and show pieces of those pathogens on their surface so the body’s helper T cells (which coordinate overall immune response) know to mount a response against those specific pathogens.

Kimchi also increased the activity of certain genes that act like switches, helping these immune cells send clearer signals to T cells.

There were also genetic changes in helper T cells that made them react more quickly to anything that triggers an immune response. Since helper T cells coordinate immune responses, these changes mean they’re better equipped to help other immune cells fight infections effectively.

Most other immune cells stayed the same, meaning kimchi targeted helper T cells rather than activating the entire immune system. Maintaining this balance is important because the immune system must be able to respond to infections effectively while avoiding excessive inflammation that can damage tissues.

Overall, the results suggest that kimchi helps the immune system respond to threats more effectively without causing too much inflammation. Both types of kimchi produced these effects – though starter-culture kimchi showed a slightly stronger effect. Those taking the placebo saw no immune changes.

These findings point to potential benefits for defence against viruses, responsiveness to vaccines and regulation of inflammation – although further research is needed.

Immune cell function

It’s worth mentioning that this study was small and focused on changes in immune cells, not actual health outcomes. So we don’t yet know if eating kimchi in this way would reduce infections or inflammation in daily life.

However, the study does provide a plausible molecular explanation for how fermented foods can influence immune function. This tells us more than we can learn from studies that only observe people’s habits. It links a common fermented food to measurable effects on immune cells – supporting the idea that fermented foods may be used strategically to enhance immune regulation and overall immune balance.

Kimchi isn’t the only fermented food that may have immune benefits. Other foods such as yogurt, kefir, sauerkraut, miso and kombucha contain live microbes and metabolites that have a positive effect on the microbiome and may influence immune function.

Some studies have also shown that fermented dairy products can increase beneficial gut bacteria and modulate immune responses, including T cell and antibody activity.

The exact effects of fermented foods will depend on many variables, including the microbes present, the fermentation method and an individual’s unique gut microbiome.

Different fermented foods may also have different effects due to the microbes they contain. This is why including a variety of fermented foods may be more beneficial than relying on a single type.

There’s no established recommendation for how much fermented food to eat. In this study, participants consumed the equivalent of 30 grams of kimchi per day, an amount that is feasible for most people.

While research is still unfolding, including a variety of fermented foods in your diet is an easy and enjoyable way to explore the potential benefits for your gut and immune system.

Try new options to discover what you like best, keep a few favourites ready in the fridge, and find simple ways to add them to everyday meals. Over time, these small, regular habits could help support your gut and immune health.
