A particle accelerator that produces intense X-rays could be squeezed into a device that fits on a table, my colleagues and I have found in a new research project.

The way that intense X-rays are currently produced is through a facility called a synchrotron light source. These are used to study materials, drug molecules and biological tissues. Even the smallest existing synchrotrons, however, are about the size of a football stadium.

Our research, which has been accepted for publication in the journal Physical Review Letters, shows how tiny structures called carbon nanotubes and laser light could generate brilliant X-rays on a microchip. Although the device is still at the concept stage, the development has the potential to transform medicine, materials science and other disciplines.

Most people imagine particle accelerators as enormous machines, very large rings of metal and magnets stretching for kilometre beneath the ground. The Large Hadron Collider at Cern (the European Organization for Nuclear Research) in Geneva, for example, is 17 miles (27km) long.

The new research shows that it may soon be possible to build ultra-compact accelerators only a few micrometre wide – smaller than the width of a human hair. These could generate coherent, high-energy X-rays similar to those produced by billion-pound synchrotron facilities, but using devices that fit on a microchip.

Twisted light

The principle relies on a particular property of light known as surface plasmon polaritons. These are waves that form when laser light clings to the surface of a material. In the simulations, a circularly polarised laser pulse was sent through a tiny hollow tube. This polarised laser pulse is light that twists as it moves, very much like a corkscrew.

The swirling field traps and accelerates electron particles inside the tube, forcing them into a spiral motion. As they move in sync, the electrons emit radiation coherently, amplifying the light’s intensity by up to two orders of magnitude.

My team and I have created a microscopic synchrotron, where the same physical principles that drive mile-scale facilities play out – but on a nanoscopic stage.

To make this concept work, carbon nanotubes were used. These are cylindrical structures made of carbon atoms arranged in hexagonal patterns. These nanotubes can withstand very high electric fields, hundreds of times stronger than those in conventional accelerators. They can also be “grown” vertically into what we call a “forest” of closely aligned hollow tubes.

This unique architecture provides an ideal environment for the corkscrewing laser light to couple with the electrons. The circularly polarised laser fits the nanotube’s internal structure – much like a key in a lock which is why we refer to a quantum lock-and-key mechanism.

The research team that I’m a part of was led by Bifeng Lei, research associate in the school of physical sciences. 3D simulations showed that this interaction can produce electric fields of several teravolts (one trillion volts) per metre. This is far beyond what current accelerator technologies can achieve.

That kind of performance could change who gets access to cutting-edge X-ray sources. At present, scientists must apply for limited time slots at large, national synchrotron facilities, or free-electron lasers, often waiting months for a few hours of beam time.

Opening up access

The tabletop accelerator approach could make this capability available in hospitals, universities and industrial labs. In fact, wherever it is needed.

In medicine, this could mean clearer mammograms and new imaging techniques that reveal soft tissues in unprecedented detail, without contrast agents. In drug development, researchers could analyse protein structures in-house, dramatically speeding up the design of new therapies. And in materials, science and semiconductor engineering, it could enable non destructive, high speed testing of delicate components.

The study was presented at the 2025 NanoAc workshop on the topic of nanotechnology in accelerator physics, which was held in Liverpool earlier this month. The research currently remains at the simulation stage. But the necessary components already exist: powerful circularly polarised lasers and precisely fabricated nanotube structures are standard tools in advanced research labs.

The next step is experimental verification. If successful, this would mark the beginning of a new generation of ultra compact radiation sources. What excites me most about this technology is not just the physics, but what it represents.

Large-scale accelerators have driven enormous scientific progress, but they remain out of reach for most institutions. A miniaturised accelerator that delivers comparable performance could democratise access to world-class research tools, bringing frontier science into the hands of many more researchers.

The future of particle acceleration might include very large machines to further push the energy, intensity and discovery boundaries, as well as smaller, smarter and more accessible accelerators.

Society is fascinated with health, fitness and longevity. This obsession has spawned a multi-million pound industry centred around pushing the latest cutting-edge science, lifestyle modifications and products that claim to prevent ageing and live as long as possible.

But the secret to a long life doesn’t have to be so complicated. There are many simple things everyone can do to slow down time and feel younger.

When we talk about age, we aren’t always talking about how many candles are on your birthday cake. We actually have two different ages.

The first is of course chronological age. This is the number of years you’ve been alive.

But we also have a “biological age.” This is sometimes referred to as “true age” or “internal body age.” This refers to how well all of the body’s internal systems are functioning by looking for signs of ageing in the cells, blood and DNA.

Research indicates that a person’s biological age, rather than their chronological age, is related to how long they live. Let’s say you looked at two 60-year-old people. The person whose biological age is younger would be more likely to outlive the person who had a higher biological age.

There are now many ways to measure your biological age with epigenetic testing, which only requires a little bit of spit and can be done at home. The saliva sample is then processed in a lab where the DNA is extracted to get information about what’s happening in the body.

The everyday lifestyle choices we make affects our biological age. While some of the decisions we make can increase it (such as drinking, smoking or being inactive), other factors can actually turn back the clock. Thus, how long we live may truly be in our hands.

Here are five evidence-backed ways of reducing your biological age:

1. Run away from ageing – literally

Being more physically active and regularly exercising throughout life reduces risk of death from all causes – directly increasing longevity.

It’s also never too late to get started. One study found that sedentary people who adopted an eight-week exercise programme (60 minute workouts done three times a week) reversed their biological age by around two years.

A mixture of strength and endurance exercises done three to four times a week (with sessions as short as 23 minutes) is also shown to significantly reduce ageing.

Exercise influences something called DNA methylation, a process which controls whether certain genes are “on” or “off.” As we age it’s natural that our genes start switching off – this is why we get winkles and grey hair.

But exercise helps to slow these processes down, meaning the genes that help do important functions in the body continue doing their job for longer.

2. You are what you eat

Making healthier food choices directly reduces biological age. This effect is even greater in those with chronic disease and obesity.

One study, which looked at nearly 2,700 women, found that adopting healthier eating patterns for 6-12 months was a key factor in staying younger for longer. This diet was also shown to slow ageing by an average of 2.4 years.

Healthier food choices included eating more fruits, vegetables, whole grains, nuts, legumes, fish, lean proteins and healthy fats (such as oil) and reducing intake of red meat, saturated fat, added sugars and sodium.

A well-balanced diet provides antioxidants, vitamins and anti-inflammatory compounds that help cells repair damage and reduce stress on our DNA. These nutrients also influence DNA methylation.

3. Improve sleep habits

Sleep is one of the strongest predictors of healthy ageing because it affects nearly every bodily system. Good quality sleep allows the body to repair DNA, restore hormonal balance, reduce inflammation and clear cellular waste – helping the immune, metabolic and nervous systems stay youthful and resilient.

One review showed that sleep quality is directly associated with how fast we age. People who sleep less than five hours per night have a significantly increased risk of age-related diseases such as diabetes, heart disease, cancer and dementia.

Additionally, a large UK study of nearly 200,000 participants found that those on shift work – and particularly night shifts – had a biological age around one year higher than their counterparts who worked at normal hours.

4. Avoid unhealthy vices

Habits such as vaping, smoking and drinking alcohol are the strongest and most consistent accelerators of ageing.

Smoking, for instance, is shown to rapidly age the lungs by up to 4.3 years and the airway cells by nearly five years.

Similarly, a study looking at 8,046 adults aged 30–79 years old found that consuming any amount of alcohol was associated with accelerated biological ageing. The more alcohol consumed the more age is accelerated.

These habits speed up biological ageing because they directly damage DNA, increase inflammation and overload cells with stress. This causes the body and organs to work harder – ageing them quicker.

5. Master your mind

Stress management is key. Research shows that being able to regulate emotions and manage stress levels predicts age acceleration. Another study found that working more than 40 hours a week on average increased biological age by two years, probably due to the stress.

Stress can directly accelerate biological age due to the way it affects hormonal response, damages DNA and reduces immunity. Stress can also indirectly affect other factors that may accelerate age, such as diet, sleep and whether we drink or smoke. This is why having a set of positive coping mechanisms to manage stress is so important.

A growing body of research is also showing that factors such as loneliness, exposure to extreme heat and cold, air pollution and our environment (such as living in deprived areas) can all also affect how we age.

It’s important to note that the affect of these factors on age may vary depending on the person, their genetics, how long they’ve stuck with these lifestyle habits and other factors at play.

Nevertheless, this gives insight into how changing even small habits can positively improve health and well-being and, in some cases, turn back the clock.

When we lose weight, we don’t just lose body fat – we lose muscle, too.

This can be a problem for many reasons, because skeletal muscle is far more than the tissue that helps us move. It plays a crucial role in metabolic health, regulating blood sugar and healthy ageing. Losing muscle mass is linked to a reduced mobility, increased injury risk and is thought to potentially impair long-term weight loss.

With millions of people now using weight loss drugs such as Wegovy and Ozempic, understanding what impact this muscle loss might have on their health is important.

Loss of muscle mass is also a significant challenge for athletes too, as many sports encourage them to keep body weight low while still maintaining demanding training loads and keeping their power-output high. So an energy deficit can put significant stress on an athlete’s body – but to what extent it affects their normal function, is unclear.

Yet despite these widespread implications, we still know surprisingly little about how human muscle responds at the molecular level to the combination of calorie restriction and exercise. Understanding what happens to muscle when exercising in a calorie deficit is extremely important.

Newly published research from myself and my colleagues casts light on this exact topic. We showed that weight loss accompanied by aerobic exercise might not be that bad for the muscles after all – and indeed it may have positive effects.

We recruited ten healthy, fit young men who completed two tightly controlled five-day experimental trials in our laboratory. During their first trial period, they consumed enough calories to maintain their body weight. But during the second, we reduced their daily calorie intake by 78% – a severe energy deficit.

During both trials, participants completed a tightly-controlled, 90-minute low- to moderate-intensity cycling exercise three times during each five-day period.

Throughout the trials, we measured blood markers such as glucose, ketones, fatty acids and key hormones linked to energy preservation. We did this to determine if – and to what extent – the energy deficit was affecting them.

We also collected muscle biopsies before and after each testing period. Using an advanced method called dynamic proteomic profiling, we analysed the production and abundance of hundreds of muscle proteins. This allowed us to build a detailed picture of how muscle adapts to sudden, substantial calorie restriction – even when exercise demands are maintained.

During the five days in an energy deficit, participants lost about 3kg. Hormones such as leptin, T3 and IGF-1 also dropped sharply – clear signs the body was getting into an energy preservation mode.

But inside the muscle itself, something more unexpected was happening.

Muscle tissue changes

The muscle tissue mounted a strong and surprisingly positive response to the combination of exercise and calorie restriction.

First, we saw an increase in the amount of mitochondrial proteins within the muscle – and these proteins were also being created more quickly.

Mitochondria are the power generators inside cells. They convert fat and carbohydrates into usable energy. Higher amounts of mitochondrial proteins, and faster production of them, are hallmarks of a healthier and more efficient muscle.

We also saw a clear decrease in the amount and production of collagen and collagen-related proteins.

Collagen is an abundant protein that plays a role in providing structure and strength to the muscle. However, collagen tends to accumulate in excess as we age – contributing to stiffness and impaired function.

Taken together, these changes resemble a shift toward a more metabolically youthful muscle profile.

This kind of response has also been seen in long-term calorie-restriction studies in monkeys. But this is the first time it has been demonstrated in humans.

Healthier ageing

At first glance, it seems paradoxical that the body would invest energy in maintaining or improving muscle during a time of scarcity.

Muscle tissue is demanding and costly to maintain – and movement is energetically expensive, too. Shouldn’t the body simply reduce muscle activity to save energy?

The answer to this question may lie in our evolutionary past. Humans evolved as hunter-gatherers, who often faced periods of low food availability. During those times, the ability to move efficiently – to walk and run long distances, forage or hunt – was essential for survival. A body that shut down muscle function during hunger would have been less likely to survive and reproduce.

So the protective response we observed may reflect deep evolutionary adaptations: muscles stay ready to move even when fuel is running low.

Our study involved a small number of young men who were deliberately following an extreme energy deficit for a short period of time. As such, we cannot assume identical responses in women, older adults or people who are obese or have chronic health conditions.

Future studies will need to compare weight loss with and without exercise, examine less extreme calorie deficits, include women and older adults, and measure how these molecular changes translate into actual physical performance.

Nevertheless, our findings support the idea that exercise during weight loss may protect muscle quality – and may even enhance characteristics linked to healthier ageing.

These findings also have key implications for many people. People who are taking weight loss drugs or trying to lose weight may benefit from structured exercise to help them preserve muscle quality. Older adults, who are more vulnerable to muscle loss, may especially benefit from exercising while losing weight. Athletes may approach any energy deficit with care, but know that muscle keeps adapting to exercise stimulus.

Our study shows that human muscle is remarkably resilient. Even under severe stress, when much of the body is trying to conserve energy, muscle tissue seems to respond robustly – boosting its energy-producing machinery and limiting age-related degradation.

In other words, losing weight and exercising doesn’t just help preserve muscle – it may help keep it younger.

When a house mysteriously explodes in the sleepy suburbs of south Oxford and a child goes missing in the aftermath, concerned neighbour Sarah Trafford is driven to seek the truth. As an art conservator, Trafford is way out of her depth, so she enlists the help of a private investigator, Zoë Boehm. However, the pair end up in a plot far more serious than Boehm’s usual work of checking credit ratings and tracking adulterous husbands.

This is the story of Down Cemetery Road (2003), the debut novel of writer Mick Herron, which has been adapted into an eight-part series by Apple TV. Down Cemetery Road is the second of Herron’s book series to be adapted by Apple, coming hot on the heels of the fifth season of the critically acclaimed Slow Horses, which centres on misfits and renegades navigating bureaucracy and corruption at MI5.

Like Slow Horses, Down Cemetery Road is fronted by British acting greats, with Ruth Wilson as art conservator Sarah Trafford and Emma Thompson as private investigator Zoë Boehm. It also exposes failings at the heart of British institutions, this time the UK government.

Slow Horses: high drama and comedy abound in this gripping spy thriller about reject spooks

Boehm and Trafford uncover evidence that the UK government has deliberately maimed its own soldiers during illicit chemical weapons testing on the battlefield (the Gulf war in Herron’s novel, Afghanistan in the adaptation). To an even greater extent on screen than on the page, however, this military premise feels like one of Alfred Hitchcock’s “MacGuffins”: something to get the narrative engines firing, rather than a theme for profound exploration.

As a conspiracy thriller, then, Apple’s Down Cemetery Road does not compare with such classics of British TV as Edge of Darkness (1985, exploring a shadowy expansion of nuclear power) and State of Play (2003, about corrupt links between politicians and the oil industry). But while it is politically thin, it is nevertheless satisfying as a TV spectacle.

One of the incidental delights in watching the series is to encounter stalwarts of British acting even in minor roles. Mark Benton, a PI himself in the long-running series Shakespeare & Hathaway, turns up here as an Oxford academic.

He momentarily emerges from his wineglass to reminisce about Sarah as a gifted student who memorised the whole of The Waste Land (including, he marvels, the footnotes). Sara Kestelman, best known for her career in theatre, is touching as a bereaved mother. Gary Lewis, the initially scornful father in Billy Elliot, is bracing as a Scottish skipper who believes Zoë and Sarah to be yet more English folk intent on telling “humble Highlanders” what to do.

But the star turns are Thompson and Wilson. Zoë’s sustained presence on screen actually represents a promotion from the novel, where she is surprisingly absent until the second half.

Thompson is visibly having fun as she breaks away from the buttoned-up gentility of films such as Sense and Sensibility, Howards End and The Remains of the Day that, even now, will define her for many viewers. Her language is as spiky as her punkish silver hair, such as when she talks of collecting her husband from “the fuck-up creche”.

Wilson, as throughout her film, TV and theatre career, embodies intelligence and curiosity as Sarah. We are alerted to her vigilance from the start, as we see her scrutinising a painting through her art conservator’s magnifying glasses. But if she looks outwards keenly, she has fewer opportunities as the series unfolds to turn her gaze inwards.

The adaptation is relatively uninterested in the inner lives of others, too. In Herron’s novel, even the frightening government operative Amos Crane has interiority, chafing at the bureaucratic confines within which he has to work. Here he is played by Fehinti Balogun as a robotic killer, seemingly incapable of feeling (other than briefly mourning his brother and, improbably, laughing at an episode of the BBC sitcom Keeping Up Appearances).

While characterisation is thinned in Apple’s adaptation, the action is thickened. Morwenna Banks and her co-screenwriters are unafraid to introduce fights and chases not found in Herron’s novel. In an especially thrilling sequence, Down Cemetery Road joins films such as The Lady Vanishes and Murder on the Orient Express in exploiting the suspense possibilities offered by a speeding train, with no opportunity to get off.

The spectacular sometimes takes a homelier form. The moment when Zoë eats a giant meringue is made striking when it shatters into sugary shards, an explosion scarcely less apocalyptic than that in the opening episode.

The moment is funnier than the repeated conversations between civil servant mandarin C. (Darren Boyd) and hapless underling Hamza Malik (Adeel Akhtar). Their scenes, offered as comic relief, come to grate and indicate a certain self-indulgence about the adaptation.

There are thoughtful sounds, too. Mozart’s Requiem is heard as the action reaches a deathly climax. And bebop jazz by Dizzy Gillespie plays over a scene of narrative discordance at the end of the opening episode. Particular thought has also been given to each episode’s closing music: songs such as P.J. Harvey’s Big Exit and Björk’s Bachelorette are witty, apt choices.

Over the final credits, we hear Billie Holiday’s I’ll Be Seeing You. With three more Zoë Boehm novels already written by Herron, it is an open question whether we will be seeing her again.

November 2025 marks 100 years since archaeologists first examined Tutankhamun’s mummified remains. What followed wasn’t scientific triumph – it was destruction. Using hot knives and brute force, Howard Carter’s team decapitated the pharaoh, severed his limbs and dismembered his torso. Then they covered it up.

Tutankhamun’s tomb was first discovered in the Valley of the Kings by a team of mostly Egyptian excavators led by Howard Carter in November 1922. However, it took several years for the excavators to clear and catalogue the tomb’s antechamber – the first part of what would become a decade-long excavation.

This meticulous work, as well as delays caused by friction between Carter and the Egyptian government, meant that it wasn’t until 1925 that Tutankhamun’s remains were uncovered. This milestone whipped up another wave of what has been termed “Tutmania” after the tomb’s initial discovery generated a wave of popular fascination for Egyptian archaeology.

When Carter’s team eventually opened Tutankhamun’s innermost coffin, they found the pharaoh’s body fused to the casket by a hardened, black, pitch-like substance. This resin was poured over the wrappings during burial to protect the body from decay.

Carter described the corpse as “firmly stuck” and noted that “no amount of legitimate force” could free it. In a desperate attempt to soften the resin and remove the body, the coffin was exposed to the heat of the sun. When this failed, the team resorted to hot knives, severing Tutankhamun’s head and funerary mask from his body in the process.

The autopsy that followed was devastating. Tutankhamun was left “decapitated, his arms separated at the shoulders, elbows and hands, his legs at the hips, knees and ankles, and his torso cut from the pelvis at the iliac crest”. His remains were later glued together to simulate an intact body – a macabre reconstruction that concealed the violence of the process.

Egyptologist Joyce Tyldesley has pointed out that this destruction is conspicuously absent from Carter’s public account of the autopsy. It is also absent from his private excavation records, which are available at the University of Oxford’s Griffith Institute and online.

Tyldesley suggests that Carter’s silence may reflect either a deliberate cover-up or a respectful attempt to preserve the dignity of the deceased king. His omissions, however, were documented in photos by the archaeological photographer Harry Burton. These shots offer a stark visual record of the dismemberment.

In some of Burton’s images, Tutankhamun’s skull is visibly impaled to keep it upright for photography. These images sit in grim contrast to the one Carter chose for the second volume of his work detailing the excavations, The Tomb of Tut-Ankh-Amen, published in 1927. In this sanitised image, the pharaoh’s head is wrapped in fabric, concealing the severed spinal column, presenting a more palatable view for public consumption.

As we reflect on the centenary of this examination, it is worth reconsidering the legacy of Carter’s excavation, not just as a landmark in Egyptology, but as a moment of ethical reckoning. The mutilation of Tutankhamun’s body, obscured in official narratives, invites us to challenge narratives of archaeological triumph and to look back on the past with a more critical view.

“Today has been a great day in the history of archaeology,” Carter wrote in his excavation diary on November 11 1925, when the medical examination of Tutankhamun’s remains began. But the archival evidence suggests something far more morally complicated, even grisly, lying behind the seductive glint of gold.

Around 70-90% of museum collections around the world are kept in storage . Often housed in buildings far away from their public institution, they represent a picture of hidden cultural and historical resources.

Remote storage often presents logistical and cost challenges to enabling public access to collections, and it remains an area of museum work that is easy to overlook by management, funders and policymakers. However, new projects are once again drawing attention to the value of access to both the collections and the decisions that are made about them.

In May of this year an exciting new addition to London’s Queen Elizabeth Olympic Park opened its doors to the public. Occupying a spot between four of the London 2012 Olympic Boroughs (Hackney, Newham, Tower Hamlets and Waltham Forest), the V&A East Storehouse is part museum, cultural centre, archive and leisure destination. It is the latest addition to a growing family of V&A sites.

The Storehouse describes itself as “your access-all-areas experience of the V&A collection” and offers a behind-the-scenes look at the world of museum storage. It is a chance to explore half a million creative works, from the Glastonbury festival archive, to Roman frescoes, Dior haute couture, Samurai swords, Elton John’s costumes and mid-century furniture.

The experience itself is highly polished. Visitors are greeted at the door by a friendly staff member, then guided up the stairs into the main atrium. Here they discover a beautifully curated and highly designed idea of what a museum store should like.

Open shelving displays collection items within arm’s reach of the public, and only light interpretation (short labels and QR codes) hint at their purpose and the connections between them. Between the wide-open vistas of the space and below the glass floor, the storage proper is visible.

When I visited, there was a real buzz from a steady stream of visitors seeking the perfect Instagram shot from above the glass floor. However, as an academic who recently led an AHRC-funded research project on museum storage, my interest lies in what this new museum brings to the long-running challenge of balancing collections storage with meaningful public access.

A short history of museum storage

Collections have been outgrowing collectors’ capacity to store them for almost as long as museums have been around. However, with the emergence of recognisable public institutions, collections storage became no longer a personal problem, but a professional one.

The post-second world war period in Europe saw cultural institutions rapidly gain new and expanded collections. The careful reflection of collecting boards and policies, so familiar to current day museum practice, were not yet seen as necessary.

The result was that museum collections quickly expanded beyond the capacity of their public sites and were increasingly relocated to any space the museum could find, with consequences for security, conservation and accessibility.

By 1976 this had become such a universal problem that the International Council of Museums (ICOM) and Unesco organised a conference in Washington DC called the International Conference on Museum Storage. Many of the standard procedures still used in museums today came from this meeting. For example, the fact that museum collections are now kept in clean, dry, pest-free and temperature-controlled environments. However, what sometimes seems to have been lost in this process, is the centrality of public access.

If collections are not used or even visible, why do we, as a society, continue to keep them? Nowhere else has this question become more pressing, than in the case of communities whose cultural items have been taken without permission, through colonialism, opportunism or greed.

In 2024 ICOM returned to the problem of storage with the publication of a global report titled Museum Storage Around the World. Based on feedback from museums across the globe, a familiar picture of lack of space and funding emerged.

The resulting ICOM International Committee on Museum Storage seeks to bring the discussions around conservation and safety into a proper dialogue. Questions of access, cultural ownership and return come to the fore as storage spaces increasingly become the location for discussions with collections’ community partners.

Order-an-object experience

With echoes of the 1990s trend for “open storage” galleries, pioneered in places such as the National Railway Museum North Shed, the Storehouse still contains only a small proportion of the V&A collections.

The public areas are not a museum storeroom. The items on display are all carefully selected and curated. They are, as are all museum displays, only a snapshot of the complete collection, and a compelling reminder of the vast cultural resources that remain unseen in museum storage around the world.

The Storehouse offers an innovative solution: the order-an-object experience. Visitors search the V&A catalogue online, find an item they are interested in and book a time slot to see it. While not all items are viewable at the Storehouse (some can only be seen at the South Kensington site) the experience is easy and straightforward. And unlike many institutions, the service is open to anyone, not just academic researchers. The only limitation is that slots book up quickly, so advance booking is essential.

Once in the Study Centre, visitors can observe, interact or simply commune with objects in the V&A collections, supported by a member staff trained in collections handling and customer service. The simplicity and openness of the service represents a significant change in the way collections access can be realised if given enough resources and support.

The long-term preservation of museum collections remains a complex and challenging issue. Not all collections should be kept, not all collections should be universally accessible, but nor should they be hidden away, with conversations about their future happening behind closed doors.

US president Donald Trump’s 15% baseline tariffs on EU imports may read like a throwback to old-school protectionism, designed to safeguard American jobs and manufacturing. But in today’s globalised and digitally driven economy, the risk isn’t just to steel or car factories, it’s to innovation itself.

The world’s most advanced technologies rely on complex, deeply integrated supply chains. Evidence from 2023 shows that even temporary US tariff shocks disrupted relationships between firms. And these tariffs won’t just hit the EU. They will disrupt the high-value tech ecosystems of partners like the UK – especially firms contributing to artificial intelligence (AI), semiconductor design and cybersecurity.

These industries underpin national resilience, data security and the competitiveness of advanced economies. For the UK, which often positions itself as a global innovation hub post-Brexit, the fallout could be significant.

Take ARM Holdings, the Cambridge-based semiconductor giant whose chip designs power 99% of the world’s smartphones and an increasing share of AI infrastructure.

ARM doesn’t manufacture chips itself. Instead, it licenses its architecture to firms like Apple, Nvidia and Qualcomm. That makes it a prime example of the UK’s value in the global innovation chain: high intellectual property (IP), low carbon footprint, huge reach.

ARM’s position as a vital link in the supply chain underlines another point. Trade policy aimed at traditional manufacturing sectors can inadvertently destabilise tech-intensive, IP-led sectors like semiconductors and software. This is echoed in research examining global tariff spillovers on tech competitiveness.

If tariffs are applied to components or design work linked to traded goods that cross EU or UK borders en route to US manufacturers, it introduces a layer of risk and cost to innovative firms and their global partners.

Even if a company’s work isn’t directly taxed, the uncertainty and red tape may make US firms think twice about sourcing from outside US jurisdictions. While Trump might present that as a victory for American manufacturing, in reality it could raise costs for US producers, damage innovation and make US firms less competitive in the industries he aims to protect.

It’s not just the giants at risk. In the UK, Cambridge’s wider tech cluster, sometimes called “Silicon Fen”, is home to dozens of ambitious AI firms. With operations spanning the UK, EU and US, companies like this depend on fast, flexible and trusted international partnerships to develop, deploy and refine their products. Tariff-related disruptions make collaboration harder at a time when speed is a competitive advantage.

This is not hypothetical. Tariffs reduce access to large markets – and when markets shrink, firms reduce investment in research and innovation.

What Trump gets wrong

Trump’s broader narrative suggests tariffs can bring back jobs and restore industrial power to the US. But innovation doesn’t work like that. A semiconductor isn’t made in one place. A cybersecurity system isn’t built by a single team. These are networked, iterative processes, involving researchers, suppliers, data centres and talent pools across continents. Disrupt that flow and you slow progress.

The UK is especially exposed because of its unique post-Brexit positioning. It trades independently from the EU but is still tightly intertwined with it, particularly in tech sectors.

Many UK firms use EU distribution centres to reach the US market or collaborate with EU partners on joint projects involving data, hardware or software This reflects the fact that the UK remains tightly integrated into European supply and value chains – exporting £358 billion of goods and services to the EU in 2024 alone. Tariffs targeting the EU could easily catch UK-originated components or design work as collateral damage.

Modelling has shown that Trump’s proposed tariffs could reduce EU-US trade volumes across multiple sectors, particularly in tech, where integrated production routes are standard.

Small and medium-sized enterprises and startups may find themselves most vulnerable. These firms typically can’t absorb sudden cost increases or legal complexities. Nor can they easily switch suppliers or reroute through different customs zones.

If you’re an early-stage AI company relying on a specific chip from Germany and a US cloud partner to train your model, a 15% tariff adds months of delays and thousands of pounds in costs, just to maintain the status quo.

From a policy perspective, the impact goes deeper. The UK government has championed sectors like AI, fintech and clean tech as pillars of economic growth. But these industries are only as strong as the networks that sustain them. If global fragmentation accelerates, the UK risks losing its role as a bridge between the US and the EU.

Meanwhile, countries like China continue to invest heavily in consolidating their innovation supply chains, from chip manufacturing to AI research, particularly in efforts to secure domestic control over advanced technologies and semiconductors. This is something that the US and EU have only recently begun to coordinate on.

In the short term, Trump’s tariff strategy may boost US customs revenue, which is up US$50 billion (£38 billion) a month by some estimates.

But this is not “free money”. These revenues are largely absorbed by businesses and ultimately passed on to consumers through higher prices, or to smaller suppliers through squeezed profit margins.

More fundamentally, it represents a belief that economic strength comes from protection rather than connection. But innovation has never worked that way. It thrives on collaboration, trust and scale. Tariffs may be politically effective, but economically they are the equivalent of building firewalls between teams that are supposed to be co-writing the future.

As the UK charts its post-Brexit global role, aligning itself with open, innovation-driven economies should be a priority. That means standing up for the integrity of global tech supply chains and recognising that disruption to one part of the system can reverberate far beyond its intended target.

The Middle East region, home to both oil-rich economies and fragile, conflict-affected states, remains among the most underfunded in the global climate landscape.

Equitable access to international finance is essential to combat climate change, particularly in the upcoming Baku to Belem Roadmap, which aims to mobilise US$1.3 trillion (£1 trillion) in global financing for climate action at Cop30, the UN climate summit.

The Middle East region is far from uniform. Several fragile countries in the region, including Yemen, Syria, Palestine, Iraq and Lebanon, and host countries of refugees such as Jordan, were among the top 20 recipients of humanitarian aid over the past decade.

Wars and climate change are inextricably linked. Climate change can increase the likelihood of violent conflict by intensifying resource scarcity and displacement, while conflict itself accelerates environmental damage. This article is part of a series, War on climate, which explores the relationship between climate issues and global conflicts.

While Yemen, Syria and Palestine are among the top three recipients of humanitarian aid, they receive the least funding for climate action. Yet they remain among the most vulnerable regions to extreme weather events such as frequent drought, heatwaves, and flash floods.

Responding to conflicts in the region has not only redirected finance to humanitarian efforts, but also pushed climate action further down the priority list. This is in addition to the fact that emissions from prolonged conflicts and the destruction of infrastructure are neglected because they are difficult to measure or compensate for.

A global imbalance

According to the thinktank Climate Policy Initiative’s (CPI) recent report 2025, between 2018 and 2023, 79% of finance dedicated to address climate change was mainly mobilised in three regions: East Asia and the Pacific, Western Europe and North America. This has left the Middle East and North Africa region consistently underfunded.

Where finance has flowed into the region, more than half has come from the private sector, mainly for renewable energy projects such as solar photovoltaics and onshore wind. Globally, mitigation continues to dominate in 2023. International climate finance for mitigation was 27 times higher than for adaptation.

Climate ambitions and the finance needed to implement them vary across countries in the region. The costs of implementing identified climate ambition by 2030 (so-called nationally determined contributions) of 11 countries (including Egypt, Iraq, Jordan, Morocco, Tunisia and Sudan) amount to US$570 billion. Egypt, Iraq and Morocco account for nearly three-quarters that total amount requested.

Yet international finance flows for climate action between 2010 and 2020 remain highly concentrated in politically stable countries in North Africa, such as Egypt, Morocco and Tunisia, while conflict-affected states in the Middle East are left behind.

I have researched the anticipated shift in global leadership in financing climate action following the US withdrawal from the Paris agreement. I found that between 2010 and 2021, the US disbursed US$390 billion in global development assistance, of which just over 11% (US$45.1 billion) went to the Middle East and North Africa. Yet less than 1% of this – only US$197 million – was allocated to climate action.

China, by contrast, has emerged as a major global lender, committing US$314 billion over the same period, of which more than 90% was in loans. However, its climate finance contribution remains opaque, voluntary and under-researched. Only around 6% of Chinese finance reached the region, and the share dedicated to climate action is largely unknown.

The US retreat from global climate leadership, combined with China’s growing role, raises pressing questions about the future of climate finance in the region, particularly through technology transfer and investments.

Filling the shortfall

Despite these challenges, new financial instruments may offer hope. Tools such as green bonds, carbon trading and climate debt swaps could help bridge the finance gap, particularly for indebted low- and middle-income countries.

The region already has experience with development-related debt swaps. A debt swap is an agreement between a government and its creditors to replace sovereign debt with investment commitments toward development goals (such as education or environmental protection), as a form of debt relief. Germany partnered with Jordan, France with Egypt and Sweden with Tunisia in earlier development-focused agreements.

Structuring debt swaps for climate purposes will be complex but potentially transformative. Initiatives to provide technical support for climate debt swaps, such as those by the UN’s Economic and Social Commission for West Asia, aim to achieve debt relief and promote climate action.

The private sector also has a crucial role in scaling up investments, particularly given the persistent shortfall in public finance from developed countries.

These instruments and private-sector investments may be unfeasible in conflict-affected countries due to poor economic conditions and limited capital. Supporting these vulnerable nations requires further exploration, potentially through regional initiatives with nearby stable countries.

Closing this financing gap requires more than humanitarian aid to address the adverse consequences of climate change. It demands recalibrating global finance flows, recognising the region’s specific vulnerabilities and fostering greater innovation through new tools and partnerships. Equitable access and allocation of the proposed US$1.3 billion will be essential. Without this, the region risks being left behind in the race to adapt to and mitigate climate change.

A few years ago, you might have balked if someone told you that the US president would be photographed in the White House shaking hands with a man who was a former member of al-Qaeda, an insurgent against US forces in Iraq, and had led one of the largest Syrian Islamist armed groups.

But that’s exactly what happened when Donald Trump welcomed his Syrian counterpart, Ahmed al-Sharaa, to Washington on November 10. Al-Sharaa became the first Syrian leader in history to be invited to the White House.

Al-Sharaa’s stunning ascendancy to power has seen him become an almost mythic figure in Middle Eastern regional politics. As the head of an armed group known as Hayat Tahrir al-Sham (HTS), he overthrew Syrian dictator Bashar al-Assad in 2024 and ended the family’s 50-year reign.

In the process, HTS also brought the Syrian civil war to a close. This was a brutal 13-year period in which more than 600,000 lives were lost and more than 6.5 million people were displaced.

Al-Sharaa has complicated roots in the broader al-Qaeda family, but he has long taken steps to distance himself from that legacy. His approach has been described by some observers as shifting “from jihad to politics”.

During the latter half of the war, HTS was restricted to its powerbase in the north-western governorate of Idlib. The group began to eschew terrorism by publicly breaking with al-Qaeda, and instead sought to earn trust and provide a legitimate base of governance.

Since taking control of Syria, HTS has continued this public personification of tolerance and stability. The group’s leadership regularly asserts that it is willing to accept diversity and that its primary goal with all parties – even longstanding rival Israel – is peaceful cohabitation.

Al-Sharaa has also worked hard to project a moderate image. He was recently photographed playing basketball with US military commanders – hardly the typical image most of us would have in mind of a former jihadist leader.

Some people have raised concerns that HTS is only pretending to be moderate and is hiding its true intentions. Others have noted conservative policies that were put in place while HTS was in control of Idlib.

Although the war in Syria has largely ended, it would also be naive to think that sectarian violence has disappeared. Conflicts have broken out between communities including the Druze and Sunni Bedouin groups.

There have also been a string of targeted killings against the Alawite community, the Assad family’s traditional base of support. It is in this context that al-Sharaa undertook his trip to Washington.

US-Syria ties

Since HTS took power, there has been a large international debate over how to engage with the new regime in Syria. Clearly, the approach of the Trump administration is to be pragmatic. This is not the first time that powerful figures in the US have contemplated working with al-Sharaa in some way.

As far back as 2015, former CIA director David Petraeus suggested that the US should consider working with members of HTS’s predecessor, Jabhat al-Nusra, in the battle against Islamic State (IS). And although HTS was officially listed as a terrorist organisation by the US in 2018, this approach was softened in July 2025.

The question remains of what Trump and al-Sharaa want from each other. The legitimacy granted by the trip to Washington is incentive enough for al-Sharaa, but he stands to gain more. With an aggressive and retaliatory Israel still occupying the Golan Heights and other parts of southern Syria, and regularly bombing inside Syria’s borders, al-Sharaa needs allies.

Trump has already revoked most of the US sanctions that were placed on Syria during the civil war – and suspended some more following the meeting in Washington. He will also probably play a role in unlocking World Bank funding for rebuilding in Syria.

The incentives for the US may include gaining an airbase in Syria’s capital, Damascus, that would help it rival Russia’s influence in the region. There is also a rumour that Syria will join the Abraham accords, the agreements normalising diplomatic relations between Israel and several Arab states, which Trump is pushing to expand. However, this is unlikely as long as Israel occupies the Golan Heights.

Stronger ties between the US and Syria would mean successfully turning Iran’s strongest regional ally away from it, while also helping the US further combat the IS group. During his visit to Washington, al-Sharaa publicly joined the global coalition against IS. Though, in reality, HTS has been fighting the group on the ground for years.

Many regional players have an interest in al-Sharaa’s project succeeding. Lebanon, Turkey and Jordan want an end to conflict on their borders and to see refugees return home, while Saudi Arabia is keen to steal Syria as an ally from Iran. Al-Sharaa is even in talks with Israel about a military and security agreement, and he has already visited the Russian leader, Vladimir Putin, in Moscow.

Shia-led Iraq is likely to be at best suspicious and at worst hostile to al-Sharaa, though both it and Iran may be left with no choice but to accept the new status quo. And this is to say nothing of the Kurds in north-eastern Syria. They bore the brunt of the war against IS and have already been repeatedly abandoned by Trump in their conflict against Turkish forces. They may not react positively to al-Sharaa’s plans to reunify the country.

It remains to be seen if al-Sharaa can consolidate power, end the sporadic violence in Syria and stabilise the country. An unstable Syria means an unstable Middle East, and an unstable Middle East is a problem well beyond the borders of the region.
