It’s 2:44 am. An air siren cuts through the clear night sky over Kyiv and into my sleep. Heart pounding, I rise out of bed in my seventh-floor room of the Hotel Rus. Feeling like I’m on autopilot, I walk down the stairs to the bomb shelter. Chairs are lined up in orderly rows in this basement that was once a gym. But only one elderly man in jogging pants with a travel cushion around his neck sits here.

I quietly take a seat next to him and try to figure out the threat level on my newly installed Kyiv Air Alert App. The air threat persists, but tonight people seem to have decided that sleep is more important. I, too, resolve to return to my room. I have to be awake for my lecture tomorrow at the Pinchuk Art Centre, a well-known international museum for contemporary art in Kyiv.

The lecture is the reason I am in Kyiv. As a professor of culture and technology at the University of Southern Denmark, I was invited to speak about my research on drone art.

Drone art is about using artistic practices to explore, question and reflect on military drones. Being asked to give a talk about this in Ukraine felt like a rare and important opportunity – and I didn’t hesitate to say yes.

The next day, I have some time before my talk. I take a stroll along the boulevards and the grand neoclassical buildings in the centre of Kyiv. People are out in cafes, bars and restaurants. The bustling shops are crowded with customers.

Where is the war on this blue-sky day in Kyiv, one might wonder.

But the war is here, constantly.

I spot groups of soldiers in camouflage standing on the street. A man on crutches, who carefully crosses a road junction. Statues encased in sandbags and boarded up – sheltered from air raids.

Kyiv’s central square, Maidan Square, is awash with flags and portraits commemorating fallen soldiers. The air is filled with the constant roar of generators that provide electricity during ongoing power outages.

In the evening, I finally stand in the lecture hall of the Pinchuk Art Centre to give my presentation. Young people, art students, curators, artists and older generations sit in the audience.

What can I tell them about drones – those for whom remote warfare has become a daily reality?

I talk about art, about military drones, about technology, about loss. I focus on the Ukrainian artist Lesia Khomenko, whose large format oil and acrylic works are on show in the museum.

Her painting “I’m a Bullet” (2024) is striking, as it shows the perspective of a kamikaze drone before it hits its target.

The painting is abstract, and its white, expressive brush strokes give you an impression of an explosion. Khomenko’s art does not represent iconic images of war; her work engages with questions of how remote sensing technology dehumanises the subject and raises ethical questions about how we, as an audience, “watch” war.

The search for a non-iconic visual language of war is also shared by the Ukrainian filmmakers Yarema Malashchuk and Roman Khimei.

Their recent work “Four Seasons” (2025) is a four-channel film that shows a small drone hitting a window in a living room and making a buzzing noise. Its manoeuvres echo Ukrainian youths practising drone piloting at home to prepare for possible conscription.

After my lecture, a woman who sat in the front row and eagerly took notes approached me: “My son was killed by a Russian drone strike”. We look at each other in silence. I try to find words. She gives me a slight smile and says: “Thank you for coming to Kyiv. Engaging with art can be a lifeline”. And then she hastily leaves the room.

Staying connected to life

During my time in Kyiv, in my conversations with the artists, curators and people I meet, I’m told time and again how creating or engaging with art builds resilience – how art helps people get through crisis and how art helps communities stay connected to life.

The sold-out opera houses, concert halls and theatres are proof of that. And although museums have had to protect part of their collections in shelters, they are open, and people flock to the exhibits.

On my departure day, I sit on the early morning train to Warsaw – 16 hours ahead, no flights in or out of Kyiv these days. Through the train window, birch trees pass in a blur, as we traverse snow-covered fields and quiet villages.

During the past few days, the war came closer to me than ever. It is as though I can feel it in my body, although I have only been in Kyiv for 72 hours.

I have the privilege of returning to a place of peace. Others do not.

The war does not stop at the border – it touches all of us in ways seen and unseen. In the spaces of art and culture, we can pause, reflect, and hold in our minds the lives and stories that demand to be remembered.

As OpenAI marks its tenth birthday in December 2025, it can celebrate becoming one of the world’s leading companies, worth perhaps as much as US$1 trillion (£750 billion). But it started as a non-profit with a serious moral mission – and its story demonstrates the difficulty of combining morality with capitalism.

The firm recently became a “public benefit corporation”, meaning that – in addition to performing some sort of pubic good – it now has a duty to make money for its shareholders, such as Microsoft.

That’s quite a change from the original set up.

Influenced by a movement known as “effective altruism”, a project which tries to find the most effective ways of helping others, OpenAI’s initial mission was to “ensure that artificial general intelligence […] benefits all of humanity” – including preventing rogue AI systems from enslaving or extinguishing the human race.

Being a non-profit was central to that mission. If pushing AI in dangerous directions was the best way to make money, a profit-seeking company would do it, but a non-profit wouldn’t. As CEO Sam Altman said in 2017: “We don’t ever want to be making decisions to benefit shareholders. The only people we want to be accountable to is humanity as a whole.”

So what changed?

Some argue that the company simply sold out – that Altman and his colleagues faced a choice between making a fortune or sticking to their principles, and took the money. (Many of OpenAI’s founders and early employees chose to leave the company instead.)

But there is another explanation. Perhaps OpenAI realised that to fulfil its moral mission, it needed to make money. After all, AI is a very expensive business, and OpenAI’s rivals – the likes of Google, Amazon and Meta – are vast corporations with deep pockets.

To have a chance of influencing AI development in a positive direction, OpenAI had to compete with them. To compete, it needed investment. And it’s hard to attract investment with no prospect of profit.

As Altman said of a previous adjustment towards profit-making: “We had tried and failed enough to raise the money as a non-profit. We didn’t see a path forward there. So we needed some of the benefits of capitalism.”

Capitalist competition

But along with the benefits of capitalism come constraints. What Karl Marx called the “coercive laws of competition” mean that in a competitive market, businesses have little choice but to put profit first, whatever their moral principles.

Indeed, if they choose not to do something profitable out of moral concerns, they know they’ll be replaced by a less scrupulous firm which will. This means not only that they fail as a business, but that they fail in their moral mission too.

The philosopher Iris Marion Young, illustrated this paradox with the example of a sweatshop owner who claims that they would love to treat their workers better. But the cost of improved pay and conditions would make them less competitive, meaning they lose out to rivals who treat their workers even worse. So being kinder to their workers would not do any good.

Similarly, had OpenAI held back from releasing ChatGPT due to worries about energy usage or self-harm or misinformation, it would probably have lost market share to another company. This in turn would have made it harder to raise the investment it needed to fulfil their mission of shaping AI development for good.

So in effect, even when its moral mission was supposedly paramount (before it became a public benefit corporation), OpenAI was already acting like a for-profit firm. It needed to, to stay competitive.

The recent legal transition just makes this official. The fact that a nonprofit board dedicated to the moral mission retains some control over the company in principle is unlikely to stop the drive to profit in practice. Marx’s coercive laws of competition squeeze morality out of business.

Marx and Milton

If Marx is capitalism’s most famous critic, perhaps its most famous cheerleader was the economist Milton Friedman.

But Friedman actually agreed with Marx that business and morals are difficult to mix. In 1971, he wrote that business executives have only one social responsibility: to make profit for shareholders.

Pursuing any other goal would be spending other people’s money on their own private principles. And in a competitive market, Friedman argued, businesspeople will find that customers and investors can quickly switch to other companies “less scrupulous in exercising their social responsibilities”.

All of this suggests that we cannot expect businesses to do as OpenAI originally promised, and put humanity before shareholder value. Even if it tries, the coercive laws of competition will force it to seek profit.

Friedman and Marx would have further agreed that we need other types of institutions to look after humanity. Though Friedman was mostly sceptical about the state, the AI arms race is precisely the kind of case that even he recognised required government regulation.

For Marx, the solution is more radical: replacing the coercive laws of competition with a more co-operative economic system. And my own research suggests that safeguarding the future of humanity may indeed require some restraining of capitalism , to allow tech workers time to develop safe and ethical technologies together, free from the pressures of the market.

We often throw caution to the cold, dark wind of December when it comes to spending. The cost-of-living crisis may slip our minds amid the razzle-dazzle of Christmas. We just want a moment to enjoy ourselves, to forget about the winter gloom. It’s natural for us to behave this way. Our brains are wired for it.

People in the UK spend on average an extra £700 at Christmas. The UK Office for National Statistics show increases of between 15% and 100% in the sale of books, music, computers, phones and electrical products, clothing and shoes, cosmetics and toiletries, food and alcohol in December.

But neuromarketing, a field of neuroscience that understands the way our brains respond to products, can help us to resist the urge to overspend.

The reasons we buy so much at Christmas are largely unconscious and emotional. For example, our brains are wired to avoid being left out. Social bonds were vital to our ancestors’ survival so when everyone else seems to be buying stuff and enjoying themselves at Christmas, we are motivated by evolutionary impulses to want to join in.

Our desire for new things, even when they have no intrinsic value, has evolutionary roots too. Finding and keeping new information and objects make us feel like we’re reducing uncertainties about the future. So marketing a product as the “latest” version of its kind can make it seem irresistible.

Christmas consumption – what would the great economic philosophers think?

---

Brain signals (neurotransmitters) alter our behaviour too. Dopamine drives our motivation and impulsivity for rewards. Oxytocin drives our sense of belonging, which can be stimulated by buying the same things as our friends. And cortisol levels may rise if we fear missing out.

These neurotransmitters direct our gaze when we look at adverts of products, holding our attention and then making us want to feel the reward of buying. In July 2025, researchers reviewed three years of eye-tracking data of study participants looking at the top 50 most attention-grabbing Christmas ads. They found heart-rending stories are great for capturing our attention, which make us more likely to buy the product. Images featuring emotional icons and cues such as popular celebrities, or lovable cartoon characters distract us. Distraction is known to stop us thinking about future goals (like saving money).

Why your willpower seems to evaporate

The 1970 Marshmallow Test on delayed gratification, developed by psychologist Walter Mischel, suggested that young children who could resist eating a marshmallow while the experimenter left the room would have more discipline in adulthood because their brains were wired for better self-control.

But a 2018 replication of the test found
that family background and economic situation were the key factors in whether children and later adults could delay their gratification and be less impulsive (resist eating the marshmallow). So, if there is unrest in the family or money is tight at Christmas, this could lead to faster, impulsive decisions and paradoxically over-spending on larger quantities of items we don’t really need or want.

Psychological research suggests that our willpower is most depleted when we are tired, if we have a lot to think about, or if we are cold and in need. It is a bit like overworking a muscle that needs constant energy.

This is the perfect formula for distraction at Christmas. We think of all the family and friends to buy gifts for and seek solace in the comfort of nice goods and experiences at Christmas. All this overloads our cognitive control system in the prefrontal cortex – the front part of the brain under the forehead that helps us to control our behaviour by thinking about our long-term goals. And the prefrontal cortex connects directly to the reward centre of the brain. So if the prefrontal cortex is overloaded, the dopamine-driven, fast and impulsive reward responses are likely to take over.

Fast, impulsive thinking and slow, deliberate thinking are both part of the brain’s natural activity. Christmas shopping plays on this fast, impulsive thinking. Think of time-limited deals and the sense of crisis if a child or loved one loses out on a much-desired gift.

Training our brains

Nevertheless there are ways we can strengthen our willpower to enjoy the season with a sense of balance. The key is becoming conscious of our emotions and our actions. The more we consciously notice our impulsivity, the better we will be at controlling it next time.

You could start right now by noting down any impulsive purchases you have made over the last week or month. And next time you go to buy something, ask yourself whether you are using slow or fast thinking.

And since the prefrontal cortex system is like a muscle that can be trained to
be stronger. Cognitive training on the run up to Christmas may help strengthen your
resolve. Think of playing chess online, or sudoku, or reading one of the books you might have been given last Christmas. Puzzles, reading, meditation practices that slow the mind, can all strengthen your brain’s circuits, and maybe help to be less impulsive this year.

And what about if you’re reading this while you’re in a cafe, taking a break from Christmas shopping? You can review your shopping list (or write one before you leave home) and reaffirm your plans. Remind yourself to stick to the list and budget no matter what. Research shows that planning and setting intentions prevents impulsive responses, especially if people plan a contingency in advance about what they will do if they spot a bright, shiny bargain.

If you can rein in impulsive Christmas purchases now, your future self will thank you for it.

Stroke is one of the leading causes of serious and complex adult disability; anyone reading this could be the next stroke survivor.

Every day in the UK, 240 people of all ages wake up to the effects of stroke: unable to move, see, speak or even swallow. Many survivors describe stroke as a “thief” that takes the life they once knew. Stroke affects not only the survivor but also the family, community, health services and wider economy. Although more people survive stroke than in the past, too many do so without the support needed to make meaningful recovery possible.

Six months after a stroke, 64% of survivors still have problems carrying out usual activities, 47% report anxiety or depression and 62% struggle with mobility. This pattern has been documented repeatedly in national datasets, including the UK’s Sentinel Stroke National Audit Programme, which also found that only 35.1% of eligible survivors received a six-month follow-up.

But many people live with hidden disabilities for five to eight years after a stroke, even if they appear physically well. These can include pain, fatigue, sleep problems and reduced social participation, memory loss, difficulty concentrating and sensory changes.

These long-lasting effects highlight the need for comprehensive and sustained support that matches the complexity of life after stroke. Support groups such as the Stroke Association and Different Strokes offer peer connection, information, emotional support and advocacy.

However, they cannot replace structured NHS rehabilitation, psychological care and long-term clinical follow-up, which many survivors report is inconsistent or unavailable.

What is missing for many people is reliable access to NHS-delivered therapy, mental health provision, vocational rehabilitation and regular reviews that identify ongoing or emerging needs.

There are also major practical consequences. Losing independence, being unable to return to work and facing financial pressures can have profound effects on survivors and their families. A quarter of all strokes happen in people under 65, during their most productive working years. About one third of survivors in this age group leave employment after a stroke, often resulting in significant financial instability.

This individual loss becomes a societal challenge. Stroke costs an estimated €60 billion per year across the EU (about £51 billion). Improving vocational support could help reduce this impact.

Early support means intervention as soon as someone is medically stable and beginning rehabilitation. It includes workplace assessments, gradual return-to-work planning, retraining when needed and guidance on benefits or workplace adjustments. Evidence shows that early vocational rehabilitation significantly improves return-to-work outcomes.

Traditional stroke rehabilitation includes physiotherapy, occupational therapy and speech therapy. Physiotherapy helps restore upper and lower limb movement. Speech therapy supports communication, reading and writing.

Occupational therapy helps people manage everyday tasks and rebuild cognitive skills such as working memory and flexible thinking. Despite these well-established therapies, many survivors continue to experience significant disability that affects daily functioning.

Although guidance recommends at least three hours per day of therapy delivered by rehabilitation professionals, demand vastly exceeds capacity. In reality, the average daily therapy time in many services is closer to 14 minutes.

As a result, many survivors experience gaps in long-term support, including rehabilitation, psychological care and community reintegration. Holistic, person-centred services that continue well beyond hospital discharge are essential.

Effective care must address both medical and social needs. This includes community resources such as social prescribing schemes, local neurorehabilitation hubs, peer support networks and accessible exercise programmes. It also includes caregiver support for unpaid family or friend carers through training, respite and financial guidance. Tailored rehabilitation plans are vital to ensure that support adapts as survivors’ needs change.

Innovation offers new possibilities. Technology enriched rehabilitation such as robotics, virtual reality and digital wearables can increase the intensity of repetitions, improve patient engagement and provide precise feedback on movement and performance.

The use of therapeutic robots has been shown in several trials to improve upper limb function in selected stroke patients while reducing the physical workload on therapists. Selection is typically based on clinical assessments of arm or hand impairment, cognitive capacity to follow instructions and the stage of rehabilitation.

Stroke survival has improved, but survival alone is not enough. The evidence shows that long-term disability, unmet clinical needs and preventable loss of independence continue to shape life after stroke for millions. A system built around short bursts of early rehabilitation cannot meet the needs of a condition that unfolds over years.

Improving access to therapy, psychological care, vocational support and community services is not an optional extra. It is central to giving stroke survivors the chance to rebuild their future.

Without this shift, the gap between what is possible and what people receive will continue to define life after stroke. After all, a life saved should be a life worth living.

When I worked on the latest Global Burden of Disease cancer study, a global project that tracks cancer patterns and deaths across countries, I found myself pausing as the numbers loaded on the screen. Even as a scientist used to large datasets, the scale was hard to process.

Behind every line of code was a family who might lose a parent or child to a cancer that could have been prevented or treated earlier. The projections for South Asia and sub-Saharan Africa were especially stark.

It was clear that millions of people would be living and dying with avoidable cancers in the decades ahead unless something changed.

Infectious outbreaks or antimicrobial resistance are often labelled as global health crises. Yet a quieter crisis has been gathering force for decades. Cancer is rising across every region of the world, and the steepest increases are now occurring in countries with the fewest resources.

As part of the Global Burden of Disease 2023 Cancer collaboration, a worldwide partnership of scientists who produce comprehensive estimates of disease and mortality, I co-authored a large study tracking cancer trends from 1990 to 2023 and projecting what the world could face by 2050.

For many years, cancer was widely viewed as a disease of affluence, concentrated in high income countries. Scientists now know that it affects all regions and that an increasing proportion of the burden falls on low and middle income countries.

Many of these countries are now experiencing rapid lifestyle and environmental changes along with ageing populations, but without the parallel development of screening, diagnostic or treatment capacity. Our analysis highlights how quickly this transition is unfolding.

In 2023, our analysis estimated 18.5 million new cancer cases and 10.4 million deaths across 204 countries. Nearly one in six global deaths was caused by cancer. More than two-thirds of these deaths occurred in low- and middle-income countries, reflecting the scale of the challenge in regions where access to screening, pathology and treatment remains limited.

In our study, 41.7% of cancer deaths in 2023 were attributable to modifiable risks. Tobacco, alcohol, unhealthy diets, high body mass index, air pollution and harmful workplace or environmental exposures all contributed.

Millions of cancers could be prevented each year if governments strengthened public health policies and made healthier choices easier. Prevention is not only about people’s actions. It is shaped by political decisions about what people can afford, breathe, eat and encounter in their environments.

Using more than three decades of data, we modelled future cancer trends. By 2050, the world could be facing 30.5 million new cancer diagnoses every year and 18.6 million annual deaths, almost double today’s figures.

Population growth and ageing play a part, but broader shifts in lifestyle, urbanisation, air quality and economic development are also increasing exposure to cancer risks. Without major interventions, these trends will continue.

Addressing this crisis requires more than isolated initiatives. By investing in early diagnosis, governments can proactively offer screening for cancers such as breast, cervical and colorectal cancer saves lives but remains rare in much of the world. Prevention must be treated as a global priority.

Tobacco control, air-quality regulation, obesity prevention and workplace protections are well evidenced and urgently need strengthening. Health systems also require significant expansion, from pathology labs and trained oncology staff to reliable access to affordable treatments. High-quality data is essential too. Countries cannot plan or measure progress without robust cancer registries.

Cancer is no longer a condition that mainly affects older adults. In many regions, younger people are increasingly diagnosed with cancers historically seen later in life. For them, the consequences ripple far beyond health.

Education, employment, relationships and financial stability can all be disrupted overnight. Cancer becomes a societal issue as well as a medical one. It already touches many families and, without action, will affect many more in the coming decades.

The future is not fixed. Our projections are warnings rather than certainties. Policymakers, communities and people still have the chance to influence what the world will face in 2050. The next 25 years are critical. We have the knowledge to change course. What we need now is the collective will to act.

“There is so much intrusion from all sides and corners,” a Sami reindeer herder tells me, reacting to a government decision to grant a mining permit in Gállok in the Sápmi region in Sweden’s far north.

Sápmi is the communal land of the Indigenous Sami people. Their land ranges through northern parts of Norway, Sweden, Finland and Russia.

This particular reindeer herding community in Sápmi has already been affected by expansion of huge levels of industry related to forestry and hydropower. And now there’s a planned iron ore project. A new mine and its associated infrastructure will place additional pressures on grazing lands and migratory routes.

The mining plans are a sign that history is repeating itself, another reindeer herder tells me. It is important to resist “for myself and for my children and everyone who comes after us who wants to live the life that I have lived”.

The plans to bring more industry into these lands are symbolic of how the Sami way of life has been ignored in the past. Over hundreds of years Sweden has seized land and resources in Sápmi.

Indigenous Sami land has historically, and continues to be, framed as the “land of the future”, a space that is presented as open for extraction and can be sacrificed for national development.

Industries such as mining, forestry, energy production, land intense green industry projects, and infrastructure expansion place cumulative pressure on Sami lands. In addition, the way that Sami people use land is also affected by climate change. As snow and weather conditions change, there is reduced access to pastures and lichen upon which reindeer feed.

Mining operations have been shown to displace livelihoods such as Sami reindeer herding, by cutting off animal migration routes and viable grazing lands. This threatens Indigenous cultural survival.

For instance, a freight train carrying ore that runs across reindeers’ west-east migration may pose risks to their lives or lead them away from their pastures. As a result, the land where the reindeer can graze is reduced and less accessible.

The benefits of mining to those who live in the north, where much of Swedish mining is located, is minimal. Locals report frustration about decades of failed promises that they will see significant local development from mining. They note that prominent mining towns such as Kiruna have had mines for generations in the hope of municipal development, but still do not have sufficient social service provisions. For instance, they lack access to maternity wards and other healthcare services.

Meanwhile, land disappears due to industrial expansion. For instance, in Malmberget in the high north, which is being dismantled due to the impact of mining.

What next?

Meanwhile, earlier this year a poster campaign appeared on the walls of Stockholm’s subway terminals, saying: “You are more mine than you think.” The campaign was organised by the information platform The Swedish Mine (Svenska Gruvan), which is a joint initiative by mining and processing companies to inform the public about the importance of mining in people’s daily lives.

Emma Härdmark, director of communications of Svemin (the Swedish Association for Mines, Mineral and Metal Production), said in an interview with a Swedish newspaper, Resumé, that the idea is to “move the mine closer to people”, by drawing parallels between the minerals and metals that are present in the human body and those extracted in the Swedish mines.

For instance, the calcium in our bones that we need to “move, stand up or give someone a hug” can also be obtained from limestone, which is needed for the cement and concrete used to build homes, schools, bridges and hospitals.

One of the lines in the campaign is that “without iron, both the body and society come to a halt”. Iron helps transport oxygen through the human body to help us “breathe, move and live”, it says. In the same way, iron also helps keep society alive, observers are told.

Stockholm commuters see posters saying that: “You have a heart of stone.” Since the human body resembles the materials we find in nature, “having a heart of stone may not be so bad after all,” it suggests to people in Stockholm. It is thanks to this stone heart, the campaign insists, that “you are more alive than ever before”.

This campaign differs from other mining and industry narratives which commonly aim to convince viewers of the remoteness of mining relative to people and nature. Previous information videos produced by mining companies such as LKAB, or Svemin, an association representing about 70 mining and production companies, make use of imagery of unspoiled nature, the sky reflecting in tranquil lakes, and a fisherman strolling through a meadow, for instance.

In these information videos the camera often shifts between undisturbed nature and mining tunnels, suggesting harmonious coexistence of extraction, alongside but unnoticed by, nature and people.

Sami people are not often visible in mining literature. However, in Q&A sections of the Swedish Mine and Svemin homepages, it is stated that the mining industry works to reach solutions for coexistence with Sami communities and minimal impact on land use interests such as reindeer herding.

Sami people question this claim to coexistence. A Sami artist reflects in an interview with me on the threat to Indigenous livelihoods when faced with extractive industrial expansion: “It’s almost as if you have a reindeer in a paddock and then you put a wolf in the paddock and tell them, you are supposed to get along and coexist. In the end, the one will eat the other.”

While Swedish mining is commonly presented as environmentally and socially benign, harms from extraction are numerous. Information about where mining takes place and who is living close to its negative impacts are often left out of campaigns like these. Meanwhile, Stockholm, where the poster campaign is taking place, is unaffected by the negative impact of mining. Those who have to deal with the daily realities of mining are hundreds of miles away.

Despite countless programmes and initiatives, rates of entrepreneurial intention — a marker of how willing people are to start new ventures — remains stagnant. But what if the secrets to entrepreneurial success lie not in textbooks but within the brain itself?

Imagine an approach that doesn’t just teach the mechanics of entrepreneurship but actively enhances the skills that make aspiring entrepreneurs successful? We know these include focus, creativity, resilience, cognitive flexibility, emotional regulation and an ability to make decisions under uncertainty.

And what if these critical abilities of the entrepreneurial mindset could be nurtured through neuroscience? This concept is at the core of a shift proposed in my recent book Entrepreneurship and neuroscience: researching brain-driven entrepreneurship.

By integrating advanced neuro-technologies into the research, teaching and practice of entrepreneurship, our work presents an alternative framework for fostering entrepreneurial behaviour from the ground up.

Entrepreneurship research has evolved through several distinct phases. The economic era (1870–1940) examined how entrepreneurs influenced markets. Meanwhile, the social and psychological era (1940–1970) focused on uncovering the traits and motivations that drive them. More recently, the managerial era (1920-2022) framed entrepreneurship as a structured, step-by-step process.

I and others are now proposing the “brain-driven” era of entrepreneurship education. This focuses on reshaping how we understand and support entrepreneurial success. Unlike previous approaches, this new perspective places entrepreneurial cognitive enhancement at its core, leveraging insights from neuroscience.

For example, researchers including myself have identified electroencephalography (EEG) and structured cognitive training protocols — grounded in neuroscience — as promising tools for assessing mental states. They are also key to enhancing cognitive functions linked to entrepreneurial success.

While conventional tools such as interviews, questionnaires and behavioural observation capture surface-level behaviour and self-reported experiences, EEG goes deeper – measuring the brain’s electrical activity. This makes it possible to explore attention, working memory, cognitive workload and emotional regulation in more detail.

A study at the University of Kobe indicates that EEG can detect the subtle interplay between emotions and entrepreneurial decision-making. In the experiment, participants were briefly shown emotionally charged words — such as “joyful” or “awful” — before making decisions in a risk-based game. The aim was to test whether emotional cues might subtly shift risk-taking behaviour.

While their choices didn’t change in statistically clear ways, the brain data told a different story. Participants with higher entrepreneurial intention showed distinct patterns of neural activity in response to emotional cues.

This was particularly in areas associated with attention and making meaning of things. This suggests that even when behaviour appears unchanged, the brain may be processing emotional information in ways that shape how decisions are made under uncertainty.

Brain activity in the frontal and parietal areas also revealed that those with stronger entrepreneurial intentions responded more efficiently to emotional cues. This suggests their brains may be wired to handle emotionally charged decisions differently.

While cognitive functions such as sustained attention, emotional regulation and cognitive flexibility are increasingly recognised as essential for entrepreneurial success, EEG enables us to observe how these abilities operate in real time. These capacities are central to navigating uncertainty, adapting to changing conditions and making rapid, high-stakes decisions.

Brain-aligned cognitive training

Emerging “brain-aligned methods” shed light on how to gently train the brain to support entrepreneurial development. These approaches focus on strengthening core cognitive functions increasingly associated with entrepreneurial performance.

At Xi’an Jiaotong-Liverpool University’s recent Technopreneurship Summer School, we let students take part in cognitive training. This included exercises such as maintaining focus on moving visual stimuli to strengthen sustained attention. This involved engaging in short design challenges like building a simple robot prototype and reflecting aloud on their mental processes.

This application of neuroscience within entrepreneurship education has also sparked innovation beyond classroom-based interventions. While the field is still emerging, studies in music neuroscience suggest that specific sound patterns and frequencies can influence attention, mood and cognitive performance.

A development called cognitive performance music
offers an early glimpse into how music might complement cognitive training. This is basically music designed to sharpen cognitive focus, sustain deep motivation and strengthen the cognitive dimensions of an entrepreneurial mindset.

A well-recognised example is Steve Reich’s minimalist composition Piano Phase, which has been shown to foster neural synchronisation and sustained attentional engagement across listeners. The world’s first album in this genre, Take the Leap, was produced using a proprietary neuro-algorithm developed through my ongoing work on brain-driven approaches to entrepreneurial learning.

Another example is structured frameworks like the WNYLE Method, a pioneering brain-based entrepreneurial training approach designed to enhance the cognitive and emotional capacities that drive entrepreneurial actions. It draws on neuroscience, cinematic storytelling, thematic music and guided mental exercises. Ultimately, the method follows a carefully designed sequence that mirrors how the brain processes attention, emotion and reflection for deeper learning.

These innovations highlight the potential of neuroscience to enhance how students cultivate essential skills that can be of use both inside and outside the classroom.

As neuroscience moves from the lab to the lecture hall, a new frontier is emerging — one where cognitive optimisation becomes a core component of entrepreneurial readiness.

We have long known that learning reshapes the brain’s structure and function. This underscores the strength of neuroscience to enhance entrepreneurship education. It isn’t just about imparting knowledge, but by developing the cognitive agility needed to thrive in an unpredictable world.

And perhaps the most exciting part? This is only the beginning.

Sometimes you get a small electric shock from touching your car door handle on a dry summer’s day.

The source of these shocks is a spark discharge, occurring between your body and the body of the car. These sparks happen from accumulation of static electric charge – often arising from two different materials rubbing together. This process – named triboelectric charging – was discovered in ancient Greece, where it was observed that some materials are attracted by amber when rubbed.

Triboelectricity is commonly demonstrated in classroom experiments: by rubbing plastic sticks with cat fur, or by rubbing a balloon on your hair.

Now we know that, if you were returning to a parked car on Mars, you could experience a similar shock. A new study has, for the first time, directly demonstrated electrical discharges on the red planet.

The same triboelectric process operates in volcanic eruptions on Earth, where charge is accumulated by ash particles colliding. In volcanic plumes, the build up of charge can initiate very large lightning discharges – the big cousin of smaller spark discharges. Lightning discharges are even more common in thunderstorms, however, where interactions between soft hail (graupel) and ice crystals cause charge separation.

On Earth, dust storms and dust devils – a relatively short-lived whirlwind formed from rising columns of warm air – are known to substantially electrify, through collisions between dust particles. Typically, sufficient electrification to lead to spark or lightning discharges is not achieved, owing to the ~1 bar pressure at the surface. Conversely, on Mars, the lower pressure (about 1-10% of that on Earth) means that spark discharges are likely at lesser levels of electrification.

For several decades, it has been thought that dust devils on Mars may be able to produce spark discharges. Many lab experiments shaking sand around in a low-pressure carbon dioxide atmosphere, like that of Mars, have recorded highly charged dust and discharges.

However, until now, there have been no direct observations of Martian discharges. There have been several clues to the existence of charging in the Martian atmosphere, such as dust stuck to the wheels of a Nasa rover, for example.

The new – and genuinely serendipitous – observations published in Nature show that electrical discharges are present in the Martian atmosphere.

These results stemmed from a small loop in the wire connecting a microphone on the Perseverance rover to the on-board electronics. This wire, and the microphone system connected to it, proved to be an unexpectedly effective accidental lightning detector. The SuperCam microphone was intended to observe the acoustic environment of Mars, however, small electrical transients were also detected.

In investigating the source of these transient events, it was found that some of them were followed by sounds. The authors convincingly showed that the transients were caused by spark discharges, with electromagnetic signals picked up by the coil being followed by acoustic signals from the microphone. These observations are similar to seeing a flash of light and later hearing the subsequent thunder.

From investigating the time difference between the acoustic and electrical signals, the authors find that the spark discharges occur in the vicinity of the Martian lander – just a few metres away. Further, it was found that these occurrences were more common during dust storms, or when dust devils sweep over the rover.

Generally, two independent sources of corroborating information are considered necessary for unambiguous evidence of a new phenomenon. For example, lightning at Saturn is supported by separate observations from both spacecraft and Earth. When the discharges are weak, however, detection at a distance is much less achievable or even impossible. For these weak events on Mars, in-atmosphere detection is needed. Although the same signal system was used to detect them, the electrical and acoustic signals were conveyed in very different ways.

An analogous situation might be a radio broadcast made from near a thunderstorm. The effect of a lightning strike might cause a crackle of interference to be picked up by an analogue (not internet) radio, shortly before you heard thunder on the broadcast. The same radio provides these two signals, however they would seem to be observed independently.

The finding that electrical discharges occur on Mars has various implications. Atmospheric electricity can cause chemical reactions, such as the formation of complex molecules, perhaps linked to the origins of life. There are also practical applications for future space missions.

Dust was a significant problem during the Apollo missions landing on the lunar surface, as it easily penetrates any mechanical systems. Dust protection is an important part of planning for human travel to Mars. All these problems are exacerbated when the dust creates sparks, as it could result in electronic circuits malfunctioning.

Fortunately, you won’t have to worry much when a dust devil approaches during your next road trip on desert tracks; you can just drive through it, although the experience might remind you that on Mars you might see some sparks in the dust.

Donald Trump’s campaign against Venezuela escalated recently with the US president announcing that the country’s airspace should be considered “closed”. This is a move that has preceded US military interventions in the past, perhaps most notably in Iraq in 2003.

It remains to be seen whether Trump’s declaration will be followed by military action or is just a means of raising the pressure on the Venezuelan leader, Nicolás Maduro, in an attempt to force him from office. But regardless of what happens next, what has been notable is the reaction of China.

In a December 3 briefing, Chinese foreign ministry spokesperson Lin Jian said that closing Venezuelan airspace would violate international norms and infringe on national sovereignty. Jian added that China rejects interference in Venezuela’s internal affairs “under any pretext” and called on all parties to keep Latin America a “zone of peace”.

This stance is no great surprise. China has developed strong relationships with several Latin American countries, including Venezuela, as part of a broader strategy to expand its presence in regions long dominated by the US. Trump’s threats of military action could jeopardise the influence China has built there.

China has been involved in Latin America for centuries. But its ties to the region have grown rapidly over the past 25 years or so, with China becoming an indispensable partner to many Latin American countries. Brazil is a clear example of this indispensability.

The election of Jair Bolsonaro’s right-wing government in 2018 led to expectations that Brazil would tilt towards Washington. However, such expectations were soon dampened due to China’s role as a major consumer of Brazilian goods. By 2020, China was Brazil’s largest trading partner, accounting for over 30% of total exports from the country.

Ties between Brazil and China have only deepened under Bolsonaro’s successor, Luiz Inácio Lula da Silva. This has been helped by the intensification of the US-China trade war, which has seen Brazil become a crucial alternative source of agricultural products such as soybeans that China has historically imported from the US.

This relationship has enabled China to exert economic pressure on the US. Brazil’s large soybean exports to China have increased the global supply, which has suppressed prices for all suppliers – including those in US.

China has been a similarly indispensable partner to Venezuela since the days of Maduro’s predecessor, Hugo Chávez, who took power in the Latin American state in 1999. Chávez was a keen advocate of a multipolar international order, a concept that has gained traction as Beijing’s political and economic power has grown.

Over the years, China has become the main destination for Venezuelan oil. In 2024, China bought around 268,000 barrels of oil from Venezuela on average every day – a figure that, in reality, is likely to be higher as Venezuelan oil is routinely mislabelled to bypass US sanctions.

Venezuelan oil is key for China. Beijing has been attempting to diversify its sources of natural resources in recent years as part of efforts to retain its global advantage in cheap manufacturing and wean itself off a dependency on Middle Eastern oil. Trump’s threats to intervene militarily in Venezuela may, at least in part, be aimed at challenging Chinese interests.

Indeed, the White House issued an official statement on December 2 affirming the Trump administration’s commitment to the Monroe Doctrine. Signed in 1823, the doctrine said the US would reject other countries’ influence in Latin America. A new “Trump Corollary” to the doctrine states that “the American people – not foreign nations nor globalist institutions – will always control their own destiny in our hemisphere”.

Challenging Chinese influence

Any US military action in Venezuela will probably increase paranoia across the region. Trump warned recently that any country he believes is making illegal drugs destined for the US is vulnerable to a military attack, and singled out Colombia.

On December 2, Trump told reporters at the White House that he “heard” Colombia was “making cocaine”. “They have cocaine plants”, he added. The Colombian president, Gustavo Petro, hit back immediately on social media, saying: “To threaten our sovereignty is to declare war”.

But China is unlikely to step in militarily to defend countries in Latin America from US aggression. While China has used its developmental influence there to pursue some political objectives – most notably persuading El Salvador, the Dominican Republic and Honduras to renounce diplomatic recognition of Taiwan in recent years – its engagement with Latin America has largely been transactional.

China’s strategy in Latin America is driven primarily by economic considerations, and Beijing has generally been reluctant to enter into formal alliances with states there. This hesitance to commit to defending its partners could strain relations with countries in the region that may expect Beijing to support them in the event of a crisis.

However, Trump’s Latin America campaign does provide China with some opportunities. Just as European countries concerned about Russia’s expansionist intentions have become a key market for American arms, it’s possible that Latin America becomes a lucrative destination for Chinese weaponry.

Venezuela is already buying Chinese arms, varying from riot control equipment to missiles and – possibly in the future – fighter jets. China has also sold military equipment to Argentina, Bolivia and Ecuador.

The US appears to be taking an increasingly active interest in Latin America. As outlined in its recently published National Security Strategy, the Trump administration is looking to readjust the US’s “global military presence to address urgent threats” in the western hemisphere.

Having carefully built up its influence in Latin America over many years, China’s leadership will be keeping a keen eye on how events unfold there in the months ahead.

Wood-burning stoves are booming in the UK, a cosy response to high energy prices and cost of living pressures. But this comes with a hidden cost.

So-called domestic burning is now a leading source of one of the most harmful forms of air pollution, and the UK government’s new environment improvement plan acknowledges the scale of this problem. Yet the tools the UK relies on to control stove emissions were built for a different era – and may not be up to the job.

In the new plan, domestic burning – the use of wood to heat homes – is recognised as a primary contributor to particulate matter pollution, particularly PM2.5.

PM2.5 is considered highly dangerous as the particles are so small – less than 2.5 micrometres across – that the body has difficulty keeping them out. Once inhaled, they penetrate deep into the lungs, pass into the bloodstream and enter nearly every organ, contributing to heart and lung disease. Crucially, experts generally agree that a “safe” level of exposure has yet to be determined.

Although domestic burning features prominently in the new plan, the UK already has one of the world’s longest-standing regimes for controlling stove emissions. The Clean Air Act 1956, introduced after lethal London smogs killed more than 12,000 people in three months, enabled local authorities to create smoke control areas (SCAs) to restrict which appliances and fuels could be used.

Despite some alterations, this system has barely changed in almost 70 years. In fact, SCAs cover very little of England, Wales and Scotland, and enforcement is extremely difficult. Only a fraction of public complaints ever result in a fine.

More importantly, even perfect enforcement would not solve the core problem. SCAs were designed to reduce visible smoke, not invisible PM2.5. Modern “Defra-approved” and “EcoDesign” stoves are exempt because they emit less visible smoke.

But even under ideal operating conditions, they still emit significant levels of PM2.5 – more than 300 times that of a gas boiler. Since 2010, more than 2,500 stove models have been exempted from SCA rules, steadily widening the loophole and gradually weakening the system’s ability to control PM2.5.

This is particularly concerning as wood burning is becoming more popular. The share of UK households using solid fuel increased from 8% in 2018-19 to 11.7% in 2022-23. Installations are also increasing, with the proportion of newly inspected homes containing a stove growing from 7% in 2009 to just over 10% by 2024.

This raises the risk of what researchers call the “dematerialisation fallacy”, where
efficiency gains in individual appliances are cancelled out by growing overall use. Labelling appliances as “cleaner” can unintentionally accelerate this trend by giving the impression that modern stoves are environmentally benign.

New air quality targets

The Environment Improvement Plan introduces two different PM2.5 targets. The first aims to cut annual average concentrations by 46% by 2030, while the second seeks a 30% reduction in the amount of particulates people actually breathe, compared with 2018 levels.

This is intended to maximise public health benefits, since the first target could technically be met by cleaning up a small number of hotspots, while leaving many still exposed to harmful pollution.

These stricter air quality standards bring the UK more in line with EU and World Health Organization targets. However, as the UK’s Air Quality Expert Group recently noted, their achievement will require more “overt” intervention in people’s everyday lives. The plan’s success therefore hinges on wider public engagement and effective communication of air quality issues.

Barriers to cleaner air

Unfortunately, air quality remains relatively low on the public agenda and can become embroiled in wider political disagreements – while domestic burning is often deeply valued.

In a 2024 UK government survey of over 600 people who had burned solid fuels at their property in the past 12 months, 61% considered burning to be a “right everyone should enjoy”.

Of indoor burners, 52% considered it a “necessity” – despite most (99% in England) living in homes connected to mains gas or electricity. What’s more, 39% did not consider burning to be a significant source of air pollution, and 53% did not worry about the potential health impacts.

Economic justifications have also become more pronounced. Household energy bills are much higher today than they were just a few years ago, and the increased cost of living has eroded incomes.

In the same survey, 62% of burners cited financial reasons, while almost half (48%) gave aesthetic reasons for burning. Research from 2020 – when energy and living was cheaper – had these motivations reversed, highlighting how changing circumstances can shift burning justifications.

Comparing the cost of wood burning with central heating is not straightforward. Prices vary depending on the type of wood, the efficiency of the stove, how much of the home is heated, and whether fuel is bought in bulk or sourced for free. What is considered costly also differs between households.

However, recent modelling indicates wood burning is generally more expensive than central heating. Only when most wood is obtained at little or no cost does burning become cheaper, with gas and heat pump systems remaining the more cost-efficient choice in most scenarios.

In this context, the environment improvement plan has its work cut out. While it doesn’t explain how it will achieve the new targets, the plan does commit to consulting on new interventions – a much-needed step, given the limitations of the SCA regime.

Much rests on this consultation. The UK is far from alone in grappling with domestic burning, and a wide range of interventions is available beyond the much-needed reform of the SCAs. These include advertising controls, installation restrictions within certain areas, burn bans during high pollution or low wind episodes, public awareness campaigns, educational resources for schools, and wider access to cleaner heating technologies for those without alternatives.

Ultimately, the complexity of the issue means no single intervention will solve the problem. The environment improvement plan holds much potential, but its success will depend on what comes next.

Cutting emissions from domestic burning requires helping people to understand the health risks, challenging the idea that modern stoves are harmless, and providing practical alternatives for those who rely on burning.

If the government is serious about meeting its new air quality targets, it must treat behaviour, information and public engagement seriously as central pillars of its strategy.
