Just as humans have historically gathered during winter, many animals do the same. Animals may not be exchanging presents or decorating their nests and dens but a lot of species become more social in winter – even ones that are normally solitary.

Animals have more to worry about this time of year than bickering relatives or the last date for Christmas post. Winter poses severe challenges for wildlife, from freezing temperatures to a scarcity of food. One of the main reasons animals aggregate during the winter is to keep warm. Some species avoid these harsh conditions by migrating to warmer areas, such as cuckoos in the UK overwintering in central Africa. Others grow insulating coats (like mountain hares in the Scottish highlands), or develop a thick layer of blubber (grey seals and harbour porpoises for example) to keep the cold at bay.

But some animals come together instead. Brandt’s voles inhabit the grasslands and steppe of inner Mongolian, where winter temperatures drop as low as -30 °C and strong winds and blizzards are frequent.

During the summer months, the voles are largely solitary. However, throughout the
long, harsh winters, they form small huddling groups of around four in the nesting chambers of their underground burrows to share body heat. Huddling conserves energy by reducing resting metabolic rate by up to 37% and limits heat loss.

Safety in numbers

Arctic hares live in one of the harshest environments on Earth in northern Canada
where the long winters last up to nine months and temperatures can drop to -40°C.
During this time, they abandon their solitary summer habits and form large aggregations of up to a hundred hares.

The purpose of this behaviour is not for thermoregulation, since they do not come into close contact. Rather, it is for safety against predators. When Arctic hares form winter groups, they are increasing vigilance against predators including Arctic foxes and wolves.

A major advantage for prey species living in a group is that each animal can spend less time on the lookout for predators (and more time feeding). This is crucial for Arctic hares in winter when food is scarce and they need more energy to keep warm.

Larger groups also cause predator confusion, making it harder for predators to target individual animals. The group dilution effect means that in the event of an attack each hare’s chance of being caught is reduced.

Information network

Rooks are highly social birds living in small flocks of typically ten or fewer unrelated birds all year round. During the winter months many small flocks will join up to form huge colonies of hundreds or thousands of birds from the surrounding area.

Buckenham Carrs woodland in Norfolk has the largest rookery in Britain where an estimated 50,000 rooks have been gathering every winter for centuries. Each evening birds travel to the roost from across the Norfolk Broads, sometimes up to 20 miles, when the bare trees become foliated with rooks.

During the day, the rooks go off in smaller foraging groups and then return to the roosts each evening. Roosting closely together not only helps reduce heat-loss but also makes it easier to find food. These large communal roosts also function as information exchange centres about where the best places to forage are.

When rooks leave their roosts in the morning, they pay close attention to inadvertent cues given by other rooks such as their body condition (as an indicator of recent foraging success) and the direction in which they fly. Less successful rooks copy their more prosperous roost mates. Group foraging is more efficient and therefore reduces exposure to danger.

Water conservation

Another example of the benefits of winter groups is water conservation. Ladybirds
enter a physiological dormancy, called diapause, which allows them to survive the
winter months without feeding. During this period, they form clusters of hundreds or even thousands of ladybirds, which helps conserve energy, as clustered individuals have lower metabolic rates.

Moreover, these aggregations create a microclimate with more stable temperatures and higher humidity, which helps reduce the risk of desiccation, as ladybirds do not consume water during overwintering.

In addition, ladybirds gain extra protection when they form large clusters because their warning colouration, advertising their toxicity, is more obvious to predators.

In the UK, native seven-spot ladybirds aggregate under tree bark or leaf litter, whereas the non-native harlequin ladybird prefers houses and pack together in huge numbers around windows and in lofts during the winter.

Record warm temperatures for both spring and summer in the UK during 2025 may have led to a surge in insect populations. This may explain why many people have noticed large clusters of ladybirds around windows in their homes.

If you find a cluster of ladybirds in your home, it is best just to leave them alone as they pose no risk to people or wooden surfaces. Plus, long term data indicates insect populations are dwindling.

Reproductive advantage

In the cold prairies of Manitoba (Canada), red sided garter snakes congregate in
communal, overwintering dens, sometimes by the thousand. Snakes rely on existing underground structures such as the abandoned burrows of chipmunks, disused wells or limestone sink holes to overwinter. These snakes detect and follow the pheromone trails left by other snakes, which leads them directly to the communal dens.

This seasonal assembly not only increases survival rate during the winter months but also facilitates mating success come the spring. The close proximity of males and females after emergence reduces the time spent searching for a mate during the
short northern breeding season. Courtship begins immediately upon emergence from the dens. Multiple males coil around single females in a “mating ball” ensuring the chances of mating before the females disperse.

This seasonal social behaviour are adaptations for survival in harsh conditions. Similar to many animal species, early humans likely congregated during severe winters to share warmth and resources, illustrating a shared strategy for survival in challenging environments. Understanding this behaviour is vital as climate change alters winter severity and availability of food and shelter.

Most people outside of banking won’t have heard of Euroclear. It’s a Brussels-based settlement provider that enables the transfer of ownership of securities between seller and buyer. The firm is the focal point of a major geopolitical confrontation between Russia and the European Union.

The controversy stems from an EU initiative to leverage frozen Russian assets held at Euroclear to finance Ukraine’s war effort. In response, Russia’s central bank has filed a lawsuit in Moscow seeking damages for the freezing of its assets.

This legal manoeuvre represents an attempt to seize assets worth €17 billion (£14.89 billion) held by Euroclear in Russia on behalf of its clients and pursue further claims on similar Euroclear assets in other jurisdictions not part of the international sanctions imposed on Russia. These could include China, Hong Kong and states in the Gulf and Central Asia.

To appreciate the implications of these competing claims, it is essential to understand Euroclear’s role and origins.

Euroclear functions as a central securities depository (CSD). These are invisible, yet vital, pieces of infrastructure for financial markets. The function of a CSD is to transfer ownership of securities – titles of ownership of financial assets – from seller to buyer once payment is confirmed.

Euroclear is an international CSD. This means it handles not just equities traded on a particular stock exchange like national CSDs do, but a vast range of financial instruments across many markets and jurisdictions.

This includes Eurobonds, supranational agency bonds, government and corporate debt, money market instruments, asset-backed securities and more. It also provides critical collateral management and securities borrowing and lending services.

In 2024, it processed 331 million transactions worth €1,162 trillion (£877 billion) and held more than €40 trillion of clients’ assets.

This privileged position depends on trust. Depositories such as Euroclear process ownership changes via book-entry transfer. That means assets are held by the CSDs and recorded in a database of holdings, which confers legal ownership of the titles. This ensures uncontested and efficient transactions and reduces the risk of one side of a trade not fulfilling its obligations.

If the trust that allows market participants to assign their assets to a CSD like Euroclear for safekeeping falters, the book-entry transfer system breaks down and markets suffer.

Risks of EU’s plan

The EU’s plan to use frozen Russian assets as collateral for loans to Ukraine introduces significant risks. If market participants fear politically motivated asset seizures, they may relocate holdings to jurisdictions perceived as safer. This could potentially weaken Euroclear’s position and destabilise the markets it serves.

The recent EU proposals have evolved to avoid outright seizure of the Russian assets. Instead it has opted for freezing them indefinitely. Under this arrangement, legal ownership remains with Euroclear’s Russian clients, while Euroclear uses these assets as collateral for loans to the EU to finance Ukraine.

But this raises important questions. What happens if sanctions are lifted or Russia’s legal challenges are successful? Could Euroclear demand immediate repayment from the EU? And could Euroclear withstand the financial strain of restoring all these assets to their Russian owners en masse? These uncertainties are a threat to Euroclear’s stability – and, by extension, the smooth operation of the global markets it serves.

Even unsuccessful litigation on the side of Euroclear’s Russian clients could freeze Euroclear’s holdings at national CSDs in non-sanction jurisdictions for prolonged periods. This could create operational problems for Euroclear and unsettle its clients.

The European Commission has suggested that Euroclear compensate clients for Russian-related losses using its immobilised Russian funds. But this would mean fewer funds available for loans to the EU for financing Ukraine.

The issues above are further complicated by Euroclear’s history and its part in the vast multitrillion dollar Eurodollar and Eurobond markets for offshore currency deposits and debt securities. Founded in 1968 by Morgan Guaranty Trust in Brussels, Euroclear supported the burgeoning Eurodollar and Eurobond markets.

These markets were based on offshore dollar pools that included Soviet dollar deposits seeking refuge from US jurisdiction during the cold war.

Belgium and Euroclear had an interest in nurturing Soviet trust. This was formalised in the 1989 Belgium–Luxembourg Economic Union–USSR bilateral investment treaty that is still in force between Belgium and Russia.

The treaty guarantees fair treatment, protection against expropriation, free transfer of funds and provides for dispute resolution and arbitration mechanisms. Allowing Russian assets to be used as loan collateral may be in breach of that treaty.

European financial leadership under threat

Europe’s world leadership in offshore currency and debt markets and the international financial infrastructures that support them) was achieved in the 1950s and 1960s due to perceived political risks in the US. But it’s now threatened by similar perceived risks in Europe if this plan to leverage Russian assets against its will is realised.

Euroclear is a rare example of a European global financial services champion which could provide valuable economic returns to fund Europe’s future ability to counter external threats. This could be both directly, through the generation of revenues and taxes, as well as indirectly.

Euroclear acts as part of a backbone for the EU’s financial infrastructures. It helps make Europe a central and critical part of the global financial system, enhancing market integration in Europe and across the globe, and channelling large reserves of international capital into the European financial system.

A misstep now could damage that competitive advantage, as well as cause financial turmoil and – in the longer run – potentially divert asset flows away from Europe to other, competing jurisdictions.

Loneliness is the pain we feel when our social connections fall short of fulfilling our needs. At its core, it reflects a fundamental human need: to feel close to and connected with others. But it is also often an invisible experience.

Loneliness is not just a personal issue. It is also a workplace one. Gallup’s 2025 global workplace report showed that 22% of employees felt lonely on their previous workday. Managers weren’t immune either: 23% of them reported feeling lonely.

Workplace loneliness can affect anyone and can quietly damage engagement, wellbeing and performance. For leaders, the stakes are high. When they experience loneliness, it can subtly shape how they interact with their teams. They may communicate less openly, avoid feedback or appear withdrawn. A lonely leader influences their entire workplace environment, shaping team dynamics, morale and performance.

With our colleagues, Michelle Hammond (Oakland University) and Keming Yang (Durham University), we have studied loneliness in the workplace and found that managers might feel lonely due to the demands of their role and the things they experience during the workday. These things can vary from day to day.

As managers move up the hierarchy, their status and responsibilities increase, which can create distance from both their team members and peers. Building connections depends on being able to show vulnerability. But daily pressures, tough decisions and confidentiality constraints often make it difficult for managers to open up. As a result, their need for social connection can go unmet on some days, while on other days they may feel engaged and well connected.

Our research looked at the consequences of short-term loneliness among leaders. In two independent studies with UK managers, we found that fluctuations in their loneliness levels had implications for how they approached leadership.

On days or in situations when managers felt lonely, they engaged less with their work (this could be spending time on matters unrelated to work or letting others do their tasks) and lower levels of engagement with their team members (avoiding their employees, for instance).

The consequences of short-term loneliness for managers did not stop at the end of the workday. After a day in which they felt lonely, managers distanced themselves more from others in the evening. This created a loop that perpetuated loneliness into the next workday, and it helps to explain why managers sometimes feel lonely for extended periods.

But our research uncovered a key resource outside of work that helped managers mitigate the consequences of loneliness and stopped it from affecting them for a longer period. This centred on how important their relationships with family and friends were in their life – something we called “family identity salience”.

Managers who placed greater value on their family and social connections were better able to switch off from work in the evenings, and loneliness from their workday did not spill over into their home life. Loneliness still affected their leadership at work, but it didn’t lead them to withdraw socially at home. As a result, they were able to start the next workday with a clean slate.

This “family identity salience” motivates managers to create protective boundaries between their daily work and home domains. It helps them shift out of work mode and reconnect with their friends and families after work – especially important on tough days.

Not just managers

Although managers’ loneliness has the greatest implications for the health of the workplace overall, anyone can feel lonely at work sometimes, whether or not they are a manager.

It may be helpful for workers to explore which experiences and situations make them feel lonely. They could also consider the situations when their manager might feel lonely. On the other hand, some situations might make them feel close to others, including managers. Talking to peers and sharing experiences can help to raise awareness of the issue.

To prevent occasional loneliness, workers could make themselves (and others) aware of the networks and groups that offer connection. These could be immediate team members, peers, (senior) managers, colleagues in other departments or external partners. They should think about what connects them with each of these groups and the steps they can take to strengthen their connection with them.

In addition to workplace networks, employees should invest in their relationships outside work. They can remind themselves why these relationships matter, and keep family and social goals visible (with photos, reminders or personal notes) to reinforce a sense of identity beyond work. The energy and support resources that people gain from time with friends and family outside work can unlock benefits in the professional sphere too.

Workers can also take steps to sustain and expand their relationships outside of work. For example, they might be the one who arranges dates, phone calls and shared activities with the people they value.

The best way for people to shield themselves from workplace loneliness is by not placing all their eggs in their “work basket”. Building resilience by nourishing and investing in interests and connections to places and people is a good way to celebrate all the facets of what makes us human.

Viruses, as we all know, are invisibly small things that make us sick. But is that the whole story?

Zoom in close enough and you’ll discover the complex, unseen world of viruses. Some do make us sick, but many others simply exist alongside us as part of the natural world. Most are very beautiful and many, it turns out, look a bit like snowflakes.

It’s the time of year for seasonal decorations. So the MRC-University of Glasgow Centre for Virus Research has created a set of papercraft virus snowflakes you can print and cut out. They’re a fun way to explore the viruses around us this winter – and the vaccines that protect us from them.

Here are some of our favourites.

On the first day of Christmas a virus gave to me: a world that is too small to see

An elegantly decorated adenovirus, just 100 nanometres across – that’s a ten-thousandth of a millimetre, or smaller than a quarter of the wavelength of visible light.

On the second day of Christmas a virus gave to me: two twinned capsids

Many viruses use repeating protein blocks to package their genetic material (genome) into regular, rounded “capsids”. The geminiviruses of plants pull off a beautiful geometrical trick, stacking their proteins into a doubled capsid structure.

On the third day of Christmas a virus gave to me: three genome segments

Most viruses store their genes in one molecule, but some split them into segments – just like how our DNA is divided into multiple chromosomes. This virus, Heartland virus, has three of them.

On the fourth day of Christmas a virus gave to me: four COVID vaccines

There are four main types of COVID vaccine (clockwise from top left): protein subunit vaccines (which use harmless virus fragments), inactivated virus vaccines (using killed virus particles), mRNA vaccines (delivered in tiny lipid bubbles), and adenoviral vector vaccines (using a harmless virus as a delivery vehicle).

On the fifth day of Christmas a virus gave to me: FIIIIVE TIIINY RIIIIIIINGS

Anelloviruses (named after the Latin word for “ring” because of their circular genomes) are extremely common blood-borne viruses. Despite infecting almost everyone on the planet, they don’t appear to cause any disease – so they went completely unnoticed for decades.

On the sixth day of Christmas a virus gave to me: six wasps a-laying

Bracoviriforms have formed a remarkable partnership with a particular type of wasp. The wasp passes the virus’s genes directly to its offspring, and in return, the virus provides capsids (protein shells) for the wasp to use. The wasp then uses those capsids to disable a caterpillar’s immune system, allowing it to lay eggs inside the living caterpillar. Not the nicest story, but that’s nature for you.

On the seventh day of Christmas a virus gave to me: seven dogs a-barking

A vaccine made from inactivated rabies virus particles. Rabies vaccines were among the first ever developed, and, unusually, they can protect someone even after a dog bite has exposed them to this otherwise deadly virus.

On the eighth day of Christmas a virus gave to me: eight tools for teaching

Bacteriophage lambda infects the most commonly studied strain of lab bacteria, E coli. Instead of being a nuisance, it turned out to be a revelation. By manipulating its host with a clever set of genetic switches, lambda helped scientists understand how cells and genes are controlled.

On the ninth day of Christmas a virus gave to me: nine childhood vaccines

From January 1 2026, all children in the UK will be offered free vaccines against these nine viruses. They are (clockwise from top left) measles virus (the cause of measles and of measles encephalitis), varicella zoster virus (chickenpox, shingles, and a potential contributor to dementia), poliovirus (poliomyelitis and paralysis), mumps virus (mumps), hepatitis B virus (hepatitis, cirrhosis and liver cancer), human papillomavirus (cervical cancer), influenza virus (influenza), rotavirus (gastroenteritis) and rubella virus (German measles, miscarriage, congenital rubella syndrome).

On the tenth day of Christmas a virus gave to me: ten lunar landers

Bacteriophage T4 is one of the most complex and beautiful of the bacterial viruses. It lands on a bacterium like a tiny lunar module, then squats down to inject its genome and take over the cell. One small step.

On the eleventh day of Christmas a virus gave to me: eleven Christmas dinners

A wreath of ten crAssviruses – hugely abundant viruses that infect gut bacteria and are part of your normal, healthy microflora. They surround one norovirus, which causes winter vomiting disease, and is not part of your normal, healthy microflora.

On the twelfth day of Christmas a virus gave to me: twelve fights worth winning

Viruses representing pandemics or major outbreaks since the start of the 20th century: four influenza viruses (from the pandemics of 1918, 1957, 1968 and 2009), SARS-CoV-1, SARS-CoV-2, Zika virus, mpox virus, HIV, polio virus and Ebola virus.

The responses to all of these outbreaks were complex and flawed, but in every case their effects would have been far worse were it not for the tireless work of healthcare professionals, scientists and public health specialists. This work must continue – with a space for “disease X”, the ghost of viruses yet to come.

If you’d like to see more, you can download and try out the virus snowflakes for yourself, along with lesson plans and other free resources.

Imagine if a simple blood test could offer a glimpse into your future health. Not just whether you have heart disease or cancer today, but whether your overall risk of dying in the next five or ten years is higher or lower than expected.

It is the kind of idea that has hovered on the edges of medicine for decades, appearing in headlines every time a new biomarker is discovered. In practice, though, predicting long-term health has remained frustratingly imprecise. Doctors still rely heavily on age, weight, smoking history and a handful of routine blood tests, most of which provide only broad, population-level estimates.

At the same time, modern medicine is moving rapidly towards earlier detection and prevention. Health systems around the world are grappling with rising rates of chronic disease and ageing populations. Clinicians increasingly need tools that can identify risk before symptoms appear, allowing earlier intervention. The question is whether the clues to future health might already be circulating in our blood.

That is what our latest study explores. By measuring thousands of blood proteins in tens of thousands of people and tracking who survived or died over time, we found that certain protein patterns appear to be linked to a greater risk of dying from any cause other than accidents.

The analysis used data from more than 38,000 adults aged 39 to 70 who took part in the UK Biobank study. This is a long-running national health resource that collects biological samples and health information from half a million UK volunteers. Participants provided blood samples and ongoing comprehensive health and lifestyle data. We examined nearly 3,000 proteins in each blood sample and looked for proteins whose levels correlated with death within five or ten years.

After accounting for risk factors already known to adversely affect life expectancy, such as age, body mass index (BMI) and smoking, we identified hundreds of proteins linked to the overall chance of dying from any cause, and to the chance of dying from specific diseases, including cancer and cardiovascular disease.

Our research team then sifted those long lists to isolate a small number of proteins known as protein panels. These panels contained ten proteins that associated with ten-year risk of all-cause mortality, and six proteins that associated with five-year risk.

They improved forecasting ability over traditional models that rely on age, BMI and lifestyle factors. In statistical terms, models based only on demographic and lifestyle data performed poorly, with accuracy close to random. Models that incorporated the protein panels performed better, although the gains were still limited.

This suggests that some proteins in blood may carry hidden signals about long-term health that go beyond current disease. Traditional risk factors such as age, weight, smoking, alcohol consumption and physical activity offer important but often imprecise clues about health decline.

Blood proteins, by contrast, provide real-time snapshots of what is happening inside the body. Some may reflect slow chronic changes such as low-level inflammation, tissue breakdown or subtle organ stress. Others may indicate more immediate risks linked to the heart, blood vessels or immune system. Our study shows that the risk of dying can also be partially captured in the levels of circulating proteins.

Even so, this is far from a perfect test. The predictive power is better than chance but still modest. These protein signatures cannot be treated as definitive indicators of when someone will die. They could however, with further validation, function more like a warning that may prompt early action.

For example, a GP might advise more frequent check-ups or suggest earlier screening for cardiovascular problems if a patient’s protein profile looks concerning. An elevated profile does not signal imminent death. It signals a higher risk compared with someone who has a different protein pattern, everything else being equal.

Beyond diagnosis of current disease

The study also merely focused on associations. The proteins may not be causing the increased risk. They may simply be markers of underlying biological processes that have not yet produced symptoms. The authors further note that combining all causes of death into one outcome makes interpretation difficult. This is because the pathways leading to death vary widely. Heart disease, cancer, infections and organ failure each involve very different biological mechanisms.

Even with these caveats, the findings point to a future where routine blood tests may look beyond diagnosing current disease. A simple snapshot could alert doctors that a patient faces an elevated risk of health decline even when nothing obvious appears wrong. This could trigger earlier action such as closer monitoring, lifestyle guidance or preventive treatments.

This type of risk stratification is becoming increasingly important as populations age and chronic disease rates rise, placing growing pressure on healthcare systems. Such a test could help doctors target care more effectively.

Future research will determine how realistic this vision is. Large-scale validation studies in diverse populations will be needed to ensure that protein panels are accurate and reliable across different ages, ethnicities and health backgrounds. Only then can they be considered suitable for routine clinical use.

Further, any results would still need to be interpreted alongside a person’s medical history, lifestyle and symptoms. Protein panels could offer an extra layer of insight, helping clinicians build a fuller picture rather than replacing traditional assessments.

Rudy Loewe’s arresting mural The Congregation sits above the entrance to Brixton Underground station in London. The large-scale painting highlights the people and places that have shaped the area’s history over the last 75 years. It serves as a gateway into Brixton’s past and present for locals and the estimated 22 million passengers that transit through the station every year.

The Congregation is the ninth artwork in the Art on the Underground mural programme since 2000, and has been commissioned specially for Brixton tube station. Loewe is a multidisciplinary artist who blends painting, drawing and sculpture to bring aspects of history to life, unearthing histories through archival research and interviews.

Using bold and colourful imagery, the mural captures the rhythm of the everyday, showing myriad scenes, from intergenerational families to civic resistance. The viewer can move between scenes to form their own unique narrative with the mural. In some ways, it acts like a living family album for the local community.

Situated in south London, Brixton began as a wealthy Victorian commercial hub and is best known today as the symbolic heart of the UK’s Caribbean community. In 1981, the oppressive use of “Operation Swamp 81” and “sus” (suspected person) laws which affected Black youth, led to the 1981 Brixton uprising against police brutality, referred to in the media as the Brixton riots.

The mural is the result of Loewe’s research from Lambeth, London and TfL archives, as well as interviews with figures who feature in the mural and the artist’s own experience of the area. The mural cements Brixton’s historic role as a dynamic and important gathering space, particularly for Black communities.

Through 20 vivid scenes, viewers are immersed in a rich sensory landscape of Brixton over the years. From the Windrush generation, who arrived in the late 1940s, to the Frontline off-licence, a key site during the 1981 uprising, the mural captures people and places that have shaped and continue to reflect and alter the area.

One such figure is Marcia Rigg, sister of Sean Rigg who died in police custody at Brixton police station in 2008 while experiencing mental ill health. Rigg is a leading campaigner for the United Families & Friends Campaign, working alongside other families whose loved ones have died while in police custody, prison or mental health facilities.

She has been instrumental in the development of the Inquest Skills and Support Toolkit, a resource for those bereaved by a death in state custody. Loewe is conscious not to sanitise the tensions that exist, while also making it clear that “alongside grief and resistance … there is joy and sensuality” at the same time.

A living archive

Significantly, the mural also extends to marginalised voices of the Black community in Brixton and its surrounds. During the mid 1980s, Black lesbians faced isolation as they were often shut out of white queer spaces and faced homophobia within Black women’s circles.

In response to this exclusion, Eddie Lockhart and Yvonne Taylor formed Sistermatic, a Black lesbian-run sound system (which originated in 1940s Jamaica, where DJs loaded up flatbed trucks with enormous speakers, turntables and a generator to provide the music for a street party) and which features on the lower left of the mural.

For nearly a decade, Sistermatic was based at the South London Women’s Centre on Brixton’s Acre Lane. This venue functioned as a dual sanctuary: a site of communal celebration for Black lesbians, and a critical refuge for young Black queer teenagers facing homophobia. To ensure the space remained truly inclusive, the collective prioritised accessibility, offering a sliding scale for entry fees and providing a crèche for mothers.

Loewe’s research highlights that working with archives requires navigating different forms of memory and knowledge. While institutions like Lambeth Archives hold physical records, groups like Sistermatic operated on the margins of both white and Black society and left behind almost no physical archive. The sound system exists primarily as an embodied archive carried by its founders and the women who attended.

By translating these memories into visual form, Loewe performs a crucial act of restorative archiving, giving material permanence to a movement that was largely held within the collective memory of its participants. Loewe ensures that the ephemeral joy of the dancefloor is not lost simply because it was not documented on paper.

Ultimately, the power of The Congregation lies in its ability to make space for different forms of knowledge, placing the weight of institutional record alongside the embodied histories of the community. Loewe refuses to simplify this history, instead capturing the complex simultaneity where grief and political resistance coexist with joy and togetherness. It is the artist’s hope that the mural will spark new community engagement, something I experienced firsthand.

Inspired by the work, I visited Lambeth Archives for the first time to locate the Frontline off-licence documents. When I asked the archivist, she simply replied she would fetch her colleague who was there during the 1981 Brixton uprising. This interaction resonates the power in Loewe’s work, reminding us that the archive is not just a repository of the past, but a living network of people who continue to shape the present.

There are few things I look forward to more each year than an excellent Christmas lunch. In fact, I deliberately avoid roast dinners in the run-up to the big day. Especially obligatory work parties, where the turkey inevitably resembles sawdust and the stuffing has the texture of a silicone implant. Call me a snob if you like.

It is estimated that a typical Christmas lunch plate alone can clock in at at least 1,200 calories. Add a couple of glasses of bubbly and a slice of Christmas pudding with brandy butter or double cream, and you could be edging closer to, or even exceeding, 2,000. That is nearly as much as the recommended daily caloric limit for adults.

But Christmas lunch is meant to be enjoyed. And if you are going to splurge on calories, it should be on the very best food you can manage. Ideally, something that even nudges its way into the “health food” category, whatever that really means.

So let’s look at how to pack maximum flavour, pleasure and a little nutritional virtue onto your Christmas plate.

Duck, duck, duck, goose, or turkey (if you must)

I am just going to say it. I hate turkey. Or at least I hate it on Christmas Day. When smothered in cranberry sauce, sage and onions, turkey becomes largely redundant, since it tastes of very little. Cold turkey the next day is a far better deal.

Goose and duck have been our Christmas centrepieces for the last ten years. They are easier to cook, far less prone to drying out and come with a generous side benefit: the fat. Duck fat, in particular, contains higher levels of unsaturated fatty acids, including oleic acid, than other animal fats such as lard or beef dripping. Studies suggest that duck-derived fats may reduce fat-related toxicity in organs like the liver and may even have anti-obesity effects through their influence on fat metabolism.

Ducks and geese generate impressive quantities of fat during cooking, but none of it needs to go to waste. It makes exceptional roast potatoes and an unbeatable Boxing Day bubble and squeak. No fat is healthy in excess, but the higher proportion of unsaturated to saturated fats in duck or goose fat makes them a more favourable option than many alternatives.

That said, turkey does not deserve total condemnation. Turkey legs are far juicier and more flavourful than breast meat. This is due to their higher fat and collagen content, as well as a compound called myoglobin, which gives darker meat its colour. Turkey breast, beloved of bodybuilders everywhere, is also an excellent source of lean protein.

And when it comes to accompanying sauces, cranberry is the obvious choice. These tart little berries are packed with compounds that may support digestive health and immune function.

The much maligned sprout

Brussels sprouts are the unsung heroes of the Christmas vegetable line-up. Their terrible reputation almost certainly comes down to how they are cooked. Victoria Wood captured this perfectly when she described an aunt who put the Christmas sprouts on in November. An overcooked sprout is a sad thing indeed – not unlike a stripped Christmas tree lying on its side, waiting to be dragged out on 6 January.

Sprouts are nutritional powerhouses. They are rich in vitamins, particularly vitamin C and vitamin K, high in fibre, and low in fat. One hundred grams contains just 43 calories, making them ideal for piling generously onto your plate. Add chopped parsley, which is also rich in vitamins A, C, and K, and some crumbled chestnuts for complex carbohydrates, and you have a genuinely balanced side dish.

Sprouts belong to the cruciferous vegetable family, along with cabbage, kale and broccoli. These vegetables are naturally high in a compound called kaempferol. Alongside its flavour, kaempferol has been linked to anti-inflammatory effects, cardiovascular benefits and antioxidant activity, which may even play a role in the fight against cancer.

So cut a cross in the bottom of your sprouts, cook them briefly to preserve their nuttiness and nutrients, and learn to love them.

Christmas pudding as a superfood?

Christmas pudding divides opinion, often because many people’s experience is limited to grim, shop-bought versions that bear little resemblance to the real thing. While making one does take time, it is surprisingly simple, and far more nutritious than you might expect. Actor Richard E. Grant is firmly on my side here.

My go-to recipe comes from the incomparable TV cook Delia Smith, and it remains the best I have ever tasted. Packed with dried fruit and apple, it has a clear advantage over many desserts. The fibre content slows glucose absorption, leading to a gentler impact on blood sugar levels. The inclusion of dark stout, used in moderation, also brings potential benefits – including bioavailable silicon for bone health, alongside prebiotics and antioxidants.

Many Christmas pudding recipes also include other beneficial ingredients. Grated carrots add a boost of beta-carotene. Nuts and seeds provide healthy fats, and spices such as cinnamon and cloves may help support blood sugar control.

So think of your Christmas lunch not as a calorie bomb waiting to explode, but as the generous bounty it really is. A feast full of flavour, surprising nutrients, and perhaps the most important meal of the year.

And if all else fails, there is always dry January. And gruel.

Merry Christmas all.

For us linguists, the flurry of “word of the year” announcements from dictionaries and publishers is a holiday tradition as anticipated as mince pies. The words of the year aren’t just a fun peek into new slang and language changes, they also tell us quite a bit about the worries, trends and obsessions of the English-speaking world.

And this year’s list has one clear theme. In 2025, artificial intelligence (AI) played a huge role in our offices, social media feeds, music and film, and now – dictionaries.

One of the first announcements this year was Collins Dictionary, who selected “vibe coding” as their word of the year. Vibe coding refers to using AI tools to generate code rather than manually coding software programs.

When I first heard this, my initial reaction was that this is a very niche phrase, not in most people’s vocabulary. However, if we look back to Cambridge Dictionary’s selection for 2023 – which was “hallucinate”, referring to the false or nonsense responses generated by AI models – many people felt the same. Now, we regularly refer to the hallucinogenic properties of AI output, rolling our eyes at some of the answers it provides. Language can and does change, and quickly.

Such output can sometimes be described as AI slop, “low-quality content created by generative AI, often containing errors, and not requested by the user” – Macquarie Dictionary’s 2025 word of the year. The Economist and Merriam-Webster also went with “slop”, suggesting that this content, however unappealing, is a significant part of our adoption of this new technology.

“Clanker” is another word which made many of the shortlists this year, being used to as a derogatory word to describe an AI source.

Feeling like you’ve had enough of AI? For many, the opposite may be true: for its 2025 word of the year, Cambridge Dictionary chose “parasocial”, expanding the definition to account for people’s relationships with AI companions and chatbots.

Another term that reflects the AI-driven battle over authenticity is “glazing”, which appeared on Collins Dictionary’s shortlist. Defined as “to praise or flatter excessively, often undeservedly”, glazing is something that will be recognisable to anyone who’s ever asked ChatGPT to help them make a decision (OpenAI rolled back a ChatGPT update in early 2025 due to sycophancy in the chatbot).

Choosing the year’s top word

Despite what you might imagine, these words are not selected by lexicographers gathering in a secret conclave. Significant time is spent on tracking the usage of words throughout the year before making decisions on contenders.

Cambridge Dictionary tracks searches on their online dictionary and through Google on a monthly basis. Dictionary.com expands on search engine results to include news headlines and social media trends. Oxford University Press maintains a massive database of language, known as the Oxford Monitor Corpus of English, which is continually updated with automatic feeds from online media. This amounts to 150 million words per month and is a rich source of online trends for the Oxford team.

The lexicographers then come up with shortlists of words. Readers can also have their say, as many of the publishers, including Oxford University Press and Macquarie, put their choices to the public vote. The words with the most votes are then officially crowned as word of the year.

Traditionalists may argue that many of these words are in fact multiple words. But as long as they represent a “single unit of meaning”, they are considered worthy winners. Nor are they always new words. Neologisms can be a new or expanded meaning of a word which already has a lengthy history (see “parasocial” – feeling a connection with someone we don’t actually know in person – which applies to Beatlemania and Taylor Swift fans as much as AI).

Internet culture continues to provide rich pickings for words of the year. “Rage bait” was Oxford Dictionary’s selection. This involves social media content intended to manipulate users into responding negatively to a post or attacking previous responses. The posts and subsequent comments appeal to our emotions, but not in a good way. Naming this behaviour shows our increasing awareness of such manipulative techniques and hopefully, the start of many people refusing to engage with online negativity.

“Memeify”, the action of creating memes, even made Cambridge’s shortlist for 2025. My personal favourite word of the year in 2025 was driven by basketball-related memes, namely “67”, which was Dictionary.com’s choice.

This contribution welcomes generation alpha to the linguistics table. Traditionally, new slang terms would have been first used by older teenagers as they established friendships and their identities outside their families. But this year shows that our youngest generation group is seamlessly navigating online content, and in doing so, is already influencing language use.

If you’re driving home for Christmas (insert Chris Rea earworm here) – and by that I mean the old family home – you’re likely to be experiencing a familiar mix of excited anticipation and faint dread of being trapped in close quarters with relatives. There’s nothing like Christmas for mental time travel triggered by family traditions and well-worn arguments.

You might also have the sort of family, like mine, which often insists on perceiving and treating you as you were 40-plus years ago. Although I’m closer than I’d like to 50, my father still voices concerns about me crossing roads, “wrapping up warm” and leaving electric plugs switched on. I will forever be his little girl.

Since our identity is in part created by how those around us see us and behave towards us, the festive season can temporarily cause us to regress to a past, childish version of our self – and this isn’t always welcome. But I’d like to suggest there is a silver lining of opportunity here though: the chance to gain access to forgotten memories.

As a professor of cognitive neuroscience, I’ve been lucky enough to be able to test this idea with colleagues in my lab. In particular, we wanted to scientifically investigate whether people can recall more detailed childhood memories if they can “reinhabit” the body they had as a child.

I think it makes intuitive sense that this might work: the body I had as a child was very different to the one I currently occupy in middle age, and it seems reasonable to suppose that a (usually overlooked) aspect of our childhood memories – indeed of all memories – is the kind of body we used to have.

Our bodily experience is so ever-present that we usually don’t even notice it unless we are in some pain or discomfort. But there is not a minute of your life when your brain does not receive a mass of sensory input from and about your body: the sight of your hands in your peripheral vision, the sound of your footsteps and breathing, the beating of your heart, the contractions of your stomach and the tension in your muscles. Since the body is a big part of what we perceive in every moment, its varying form (as we age and change) should also be encoded in our memories.

As time passes, remote memories can dim, and some may even seem to disappear. But in most cases, they are never really “gone” from the brain – we just need the right trigger to reactivate them and bring them back into our consciousness.

A magic mental jigsaw

Memory is a bit like a magic mental jigsaw. Once you get hold of one jigsaw piece, a linking piece can suddenly pop into your mind. Our idea was to give participants in our lab the piece that enables them to re-experience their childhood bodies, in the hope that this could enable better access to memories that were laid down when they occupied those younger bodies.

We did this by causing our participants to experience a body illusion known as the “enfacement illusion”. We asked them to sit facing a computer screen with an attached webcam. On the screen, they could see a live video of their own face as filmed by the camera, but for half the participants there was a twist: the video had been distorted by a popular Snapchat app filter. Instead of seeing a video of their face as it currently looked, they saw their face morphed into a childlike version: their face resembled how it looked when they were a child.

We instructed them to move their head from side to side for 90 seconds while keeping their eyes fixed on the screen. This movement was important, as it provided crucial information to their brains about the self-relatedness of the image they saw.

Given that the face on screen moved exactly in time with their own face, this tricked the brain that the face on screen was really theirs. It was as though the participant was looking into a mirror but seeing the face they had as a child looking back at them. A different group of participants watched an undistorted video of their own face as they made the same movements.

To test whether this brief illusion has effects on memory recall, immediately after the illusion the participants took part in an “autobiographical memory interview”. The lead researcher – my former PhD student Utkarsh Gupta – followed a strict protocol to ask them a series of questions that would result in them describing an individual memory from their childhood in as much detail as possible. These interviews were recorded, and the transcripts were later numerically rated for specificity and detail by two researchers who were blind to the group that each participant had been assigned to.

Although the illusion was very brief, we found a significant difference between the memories described by participants in each group. As we had predicted, those who “re-embodied” their childlike faces were able to recall significantly more detailed memories than the participants who viewed their current face.

Our study was therefore able to show that body, self and memory interact, as indeed they must, in order for our brains to create our experience of personal identity – what makes “me” the person that I am.

Our identity necessarily evolves over time (even though our parents may sometimes have difficulty recognising that). And integrating memories of our past with the present moment is not always easy.

Our memories are not only records of the things that we previously saw, thought, smelt and heard. They are also records of the kind of body that our self used to drive around in. All our past selves are etched into our brains. The ghosts of Christmases past never really melt away.
