Smelly, dirty and a bit embarrassing – we tend to treat our poo as a private matter, to be dealt with in the bathroom and then stringently ignored. But, while we may not want to discuss toilet time at the dinner table, our bowel movements can give us invaluable information about our wider health. In this episode, we speak to Dr Trisha Pasricha, a gastroenterologist, medical doctor and assistant professor at Harvard Medical School, and the author of the upcoming, You’ve Been Pooping All Wrong. Trisha argues that we should treat our faecal matter with a little more curiosity and respect, as clues about our mood, diet, brain health – and more. She also explains how to upgrade your poops, in an effort to reach poophoria. Learn more about your ad choices. Visit podcastchoices.com/adchoices

Planet Earth is currently facing its sixth mass extinction event, with hundreds of species of plants and animals being lost for good every single day. For the first time in history, this devastating loss of the world’s flora and fauna is not being caused by natural phenomena, but by the actions of human beings. However, there is still hope that, if we start to take steps in the right direction, this looming crisis can be averted. In this episode, we’re joined by environmentalist and author Natalie Kyriacou to talk about her latest book, Nature’s Last Dance – Tales of Wonder in an Age of Extinction. She tells us how the influence of humans on the planet has become so profound that many researchers say the era we are now living in should be called the Anthropocene, talks us through some of the innovative solutions conservationists around the world are putting in place to save endangered species, and explains why we need to seriously reassess our current systems of economy, law and commerce if we are to turn the situation around.

If you were to mention the term gout, the chances are that most of us would think of the gluttonous sovereigns of yesteryear who ended up with the condition after years of gorging on rich foods and drinking fortified wines. But the fact is, cases of gout have been climbing significantly over the past few decades. So, what’s behind this increase and what measures can we all take to help us avoid this painful condition? In this episode, we’re joined by Dr Daniel Baumgardt, a GP and lecturer in health and life sciences at the University of Bristol, to talk about what happens in our bodies when we suffer from gout. He tells us how gout is caused by jagged acidic crystals forming in and around joints, how, far from only affecting the elderly, it’s beginning to affect more and more people in their 20s and 30s, and how suffering from an acute gout attack could be a warning sign that your cardiovascular system is also in poor health.

Thanks to our highly developed brains, sophisticated ability to communicate and use of advanced technology, it can be easy to think that we humans are separate from, and even superior to, the animals we share the Earth with. But the truth is that animals have profoundly influenced the progress and evolution of human beings for tens of thousands of years. In this episode, we’re joined by science writer Michael Bond to talk about his latest book, Animate – How Animals Shape the Human Mind. He tells us what the elaborate cave paintings found across the globe can teach us about our ancient ancestors’ relationship with animals, how evolution has finetuned our brains to help us recognise animals and understand their behaviour, and what we can learn about ourselves by more deeply investigating the way we treat other living beings.

The human brain is undoubtedly one of the true marvels of nature. But many of the neural mechanisms that evolved to keep our ancestors alive over thousands of years are now leaving us feeling dissatisfied, anxious and depressed thanks to the rapid advances in technology and culture we now find ourselves faced with. The simple fact is, we’re living in an environment that our brains were not built to survive in. In this episode, we’re joined by Dr Paul Goldsmith, an evolutionary neuroscientist, author and visiting professor at Imperial College London, to talk about his latest book, The Evolving Brain – An Ancient Tool in a Modern World. He tells us how the pressures and goals many of us are now confronted with are vastly different from the challenges faced by our ancestors, the huge impact this is having on our mental wellbeing by excessively triggering our natural stress responses and shares some advice from neuroscience we can all use to navigate the trials of modern life more healthily.

The natural world is filled with a rich tapestry of creatures, each occupying a unique evolutionary niche that helps to keep the ecosystems they live in functioning healthily. But the truth is, over the centuries, we humans have treated some of them better than others. Our tendency is to prefer cute, cuddly animals such as pandas or donkeys, or beautiful, majestic beasts such as elephants, eagles or tigers. Is it time that we had a long, hard look at this viewpoint, and extended our care and attention to the animals that we’ve traditionally viewed as ugly, creepy or even dangerous? In this episode, we’re joined by Jo Wimpenny an author and specialist in animal behaviour, to talk about her latest book, Beauty of the Beasts – Rethinking Nature’s Least Loved Animals. She tells us how the latest research is showing that snake venom can potentially give rise to a new category of medicinal drugs, how the insects we typically find disgusting such as maggots and cockroaches play a vital role as the natural caretakers of the environments they live in, and how, by rethinking our in-built prejudices, we can more deeply appreciate the richness and variety found in the natural world.

How can we tell if someone we’re speaking to is being economical with the truth? Oftentimes, we’re told that the primary telltale signs lie in the use of body language – maybe someone is avoiding eye contact, touching their face a lot, or fidgeting and squirming. But there’s also a whole world of clues to look out for in the type of language that someone uses when they’re telling us lies. In this episode, we’re joined by Dr Kirsty King, a lecturer in communication based at University College London, to talk about her latest book, The Language of Lies – How to Uncover the Liar in Your Life. She tells us that when people try to hide the truth, they tend to use language that distances themselves from the act they’re talking about or the people involved in it, how when we’re relating a false account of an event we tend to omit words that describe how we actually felt during it, and how even the way liars structure their sentences can be a signal that they are trying to deceive us.

Chances are that if any of us are looking to drop a bit of excess weight, the first thing we’ll attempt is to cut down the number of calories we’re consuming. For decades, we’ve been told that balancing the number of calories we put into to our bodies with the energy that we burn can help us to maintain a healthy weight. While this is true, could it be that we’re putting our attention and effort in the wrong place and that taking a bigger picture view of the factors that motivate our appetite is likely to be a much more successful strategy? In this episode, we’re joined by Dr Jason Fung, a physician and best-selling author based in Toronto, to talk about his latest book, The Hunger Code – Resetting Your Body’s Fat Thermostat in the Age of Ultra-processed Food. He talks us through the three key drivers that control our feelings of hunger, how our hormones are deeply connected with our appetites, and how the environments we live in have a profound effect on the food we eat.

Around the world, more than 50 million people are living with some form of dementia – a number expected to triple by 2050 as populations age. But the thing is, dementia is often talked about as a kind of genetic lottery. You either get lucky and escape it, or unlucky and develop it. But what if that framing is wrong? What if far more of our brain health is within our control than we’ve been led to believe? Our guest today is Dr Majid Fotuhi, a neuroscientist who has spent decades treating and studying people with cognitive impairment. His message is a bold one: dementia is largely preventable – not with a miracle pill or silver-bullet treatment, but through the way we live. The 12-week programme he and his team have developed has helped his patients improve their memory, regain independence, and even grow new brain connections. Today, he talks us through the essentials of the programme – and what it really takes to stay sharp for life. Learn more about your ad choices. Visit podcastchoices.com/adchoices

Statistics show that half of us will experience a mental health condition of some kind by the time we turn forty. Could this be due to the increasing pressures and looming crises we’re currently facing in the modern world, overstimulating natural responses in our brains and bodies that have evolved over hundreds of thousands of years to protect us from threats? In this episode, we’re joined by Dr Joanna Cheek, a psychiatrist, psychotherapist and clinical professor based at the University of British Columbia’s Faculty of Medicine, to talk about her latest book, It’s Not You, It’s the World – A Mental Health Survival Guide for Us All. She tells us how the system of alarm signals in our brains is being increasingly triggered by the rapidly changing circumstances we find ourselves in, how this is hijacking the push and pull of our natural risk/reward systems, and why connecting more deeply with the rich tapestry of the people and cultures we share the world with can help us all bring our lives back into balance.

Whether we’re working at a desk in an office, running a marathon or even asleep in bed, our bodies are host to thousands of chemical processes that are continually converting the food we eat into energy and repairing our bones, muscles and organs. Collectively these processes are known as the metabolism. But how are they affected by our genes, lifestyles and diet, and what can we do to make sure everything stays running smoothly? In this episode, we’re joined by Javier Gonzalez, a professor of nutrition and metabolism based at the University of Bath. He breaks down the links between our metabolisms and body types, tells us why our metabolisms aren’t necessarily fixed for life, and explains why it’s almost impossible to out exercise a poor diet if you’re looking to drop a few kilos.

The human face contains more than 40 muscles, giving us an ability to visually express our thoughts and emotions that is unique in the animal kingdom. This has perhaps led to a long-held obsession to uncover the many mysteries of our faces that has persisted in everyone from artists, scientists and even anthropologists for thousands of years. But where is this trend heading? And is it doing more harm than good? In this episode, we’re joined by Dr Fay Bound-Alberti, the founder of the Centre for Technology and the Body at King’s College London, to talk about her latest book, The Face: A Cultural History. She tells us how the idea of the perfectly proportioned face that began in classical art continues to persist in today’s social media beauty trends, the various attempts that have been made over the years to determine a person’s good or bad qualities based on their facial characteristics, and explains the challenges we’re currently confronted by thanks to the rise of new technologies such as facial recognition.

For the last several billion years, all life on Earth has progressed according to the rules of evolution by natural selection – a step-by-step process that has given rise to the fascinating complexity and beauty of all the living things we share our planet with. But now, due to advances in our knowledge of genetics and the rise of artificial intelligence, we’re on the brink of being able to design living organisms from scratch. This new field of research is known as generative biology. In this episode, we’re joined by Adrian Woolfson, a researcher who specialises in synthetic genome design, to talk about his latest book On the Future of Species – Authoring Life by Means of Artificial Biological Intelligence. He tells us how this fascinating area of research is bringing us closer to a genuine scientific revolution that could change the way we think about how life is created, the vast implications that this may have on human health and the health of our planet, and why we all need to be aware of this powerful new technology and its potential.

Over the past several decades, many technologists and policy makers have sought out huge, disruptive shifts in thinking in almost every area of science, business and commerce in the hope that they’d help to drive innovation forward in giant leaps, one brilliant new idea at a time. But how successful has this been, and should we instead be focusing on a more gradual, incremental approach to innovation that’s based on the steady upgrading of the systems we already have in place? In this episode, we’re joined by Albert Fox-Cahn, a visiting professor at The Centre of Governance and Human Rights at Pembroke College, Cambridge, to talk about his latest book Move Slow and Upgrade – The Power of Incremental Innovation. He tells us why we tend to overemphasise the potential impact of the Next Big Thing, how this often leads to a rush to adopt unproven, and at times, unsafe new technologies, and how applying evidence-based thinking and an upgrader’s mindset can help us to be more like the tortoise than the hare, and ultimately win the race.

If most of us are put on the spot and asked to name acts that we think would define a person as evil, it’s likely our minds would turn to murderers, rapists and war criminals, to name a few. But could it be that this commonly held conception of evil isn’t merely just an oversimplification, but rather a deeply flawed way of viewing the world based on a litany of personal biases, and one that is in dire need of readdressing? In this episode, we’re joined by Dr Julia Shaw, a broadcaster, best-selling author and psychologist based at University College London to talk about the nature of evil. She tells us why it’s vital that we accept that, given a certain set of circumstances, we’re all capable of committing terrible acts, explains the key differences between thought and action, and explains why so many of us are fascinated by true crime documentaries and dramas.

From famous actors and pop stars to the legions of social media influencers with millions of views, it seems almost everyone has something to say about the best ways to boost our health and wellbeing. But is this trend leading to many of us bypassing traditional sources of health advice and care such as GP practices and government health services and instead turning to the Internet, social media and private online pharmacies to seek out information, diagnoses, and, in some cases, even prescription medicines? In this episode, we’re joined by Deborah Cohen, an award-winning medical broadcaster and author to talk about her latest book, Bad Influence – How the Internet Hijacked Our Health. She tells us how the COVID 19 pandemic kickstarted a worldwide boom in consumer healthcare that shows no sign of stopping, why celebrities and social media stars hold so much influence over important decisions that can hugely impact our lives, and points out some of the red flags we can look out for when searching for health advice online.

While the human mind is capable of great insight, original thoughts and acts of tender kindness towards others, it can also, at times, act like our own worst enemy. Feelings of worthlessness, shame and disappointment can all stem from our brain’s natural inclination for overthinking. This can give rise to a wide range of debilitating impacts on our lives, such as low self-esteem, anxiety and depression and can even lead to the development of significant physical health issues. So, why do our minds seem to sabotage us in this way and what measures can we take to free ourselves from the common traps that lead us to being stuck in endless loops of negative thinking? In this episode, we’re joined by Dr Jessamy Hibberd, a clinical psychologist and best-selling author, to talk about her latest book, The Overthinking Cure – How to Free Your Mind and Focus on What Really Matters. She tells us how common habits such as self-criticism, comparing ourselves to others, and actively avoiding our problems can all lead us to overthink, why we are all vulnerable to getting stuck in spirals of negative thoughts, and how learning to manage where we place our attention is often the first step we can all take to help us to boost our moods and wellbeing.

From the terrifying, hulking beasts portrayed in blockbuster movies to the friendly, charismatic characters often found in children’s cartoons, dinosaurs have made their way into almost every corner of popular culture. However, in terms of scientific accuracy, such depictions tend to leave a lot to be desired. So, how do we know what dinosaurs really looked like, whose job is it to show us, and how exactly do they go about it? In this episode, we’re joined by Dr Mark Witton, a researcher, author and highly regarded paleoartist based at the University of Portsmouth. He outlines the detailed scientific process paleoartists follow to bring these ancient beasts to life as realistically as possible, runs us through some of the common mistakes Hollywood directors make in the name of artistic licence, and explains why the T.Rex is one of his favourite dinosaurs to draw.

In the world of games, scoring systems establish a framework that provides us with clear challenges, motivation, and ultimately delivers a huge amount of fun and pleasure. However, on the flip side, the increasing tendency to apply rankings and metrics to almost every area of our personal and professional lives can have a dehumanising effect, reducing our actions, performance, and even ourselves to a simple string of numbers. In today’s episode, we’re joined by C Thi Nguyen, a games researcher and associate professor of philosophy based at the University of Utah, to talk about his latest book, The Score – How to Stop Playing Someone Else’s Game. He explains how, in the real world, scoring systems typically fail to provide meaning by focusing on the simplest to measure outcomes, how purely numerical data is, by definition, lacking in nuance, and how, by concentrating on what we truly value, we can all break free from the tyranny of rankings and metrics.

Over the last several decades, the world has seen artificial intelligence undergo a rapid transformation. Since its beginnings in the 1950s as speculative theorising and novel thought experiments, AI has blossomed into a bona fide technological tool that can perform sophisticated tasks such as detecting signs of cancer or spotting signs of financial fraud, in many cases much more effectively than we humans can. But recently, another, more personal use for the technology has arisen – that of the AI companion. Against a backdrop of rising issues of social isolation and loneliness, more and more of us are turning to AI agents to act as friends, therapists and, in some cases, even lovers. In this episode, we’re joined by Dr James Muldoon, a sociologist based at Essex Business School, to talk about his latest book, Love Machines – How Artificial Intelligence is Transforming Our Relationships. He tells us how far from being a niche activity, more than 200 million AI companions have been downloaded worldwide, how many of the people who interact with them view them as being ‘real’, and why tech companies and policymakers need to work together to ensure that our relationships with AI agents remain healthy as the technology progresses.

For many of us, consuming or making art – be it listening to music, playing an instrument, reading a book, painting a watercolour or attending a dance class – is seen as a pastime or hobby, a fun way to spend an evening or Sunday afternoon. But according to the latest scientific thinking, engaging with the arts can have a profound effect on our mental and physical well-being, and may even help us to live longer, healthier lives. In this episode, we’re joined by Daisy Fancourt, a professor of psychobiology and epidemiology and head of the Social Biobehavioural Research Group at University College London, to talk about her latest book, Art Cure – The Science of How the Arts Transform Our Health. She tells us what happens in our brains and bodies when we make, perform or interact with art, how engaging with the arts may even have a beneficial effect our genes, and how medical professionals are increasingly prescribing art therapies to improve our overall health in almost every way, whether you’re three years old or 103.

There’s little doubt that we humans are a deeply social species; in many ways, our interactions with others define the very essence of who we are. But in recent times, studies have shown that we’re connecting with one another less and less, to the point where some say we may now be facing a loneliness epidemic. So, why are social interactions so vital to our health and well-being, what actually happens in our brains and bodies when we form meaningful relationships, and what measures can we take to reverse this worrying trend? In this episode, we’re joined by Dr Ben Rein, a neuroscientist, science communicator and author based at Stanford University, to talk about his latest book, Why Brains Need Friends, The Neuroscience of Social Connection – and Why We All Need More. He tells us how feel-good chemicals are released in our brains when we interact with others, how we all lie on a spectrum of introversion and extroversion and that recognising our own personalities can help us all make the most of our social interactions, and how small acts such as complimenting a stranger or putting emojis at the end of a text message can help us all to boost our social capital.

Chances are that if you open your bathroom cabinet, many of the medicines you find there were first discovered by studying the chemical processes of the plants that grow all around us. But with 450,000 plant species existing in the world, the truth is that we’re only just scratching the surface of this almost limitless resource. In this episode, we’re joined by Prof Anne Osbourn, a group leader in biosynthesis research based at the John Innes Centre, Norwich, and co-founder of drug discovery platform HotHouse Therapeutics. She tells us about the long history we humans have of making use of the medicinal properties found in plants, how technological developments over the last several decades have enabled us to identify the genes and naturally occurring processes in plants that we can harness to produce life-saving drugs, and how artificial intelligence shows great promise in our search for new, innovative medicines.

Currently, around 40 per cent of children in the UK have been diagnosed with an allergy of some form or another – the most common being food allergies, eczema, asthma, and hay fever. Why is this number so alarmingly high, what can we do to treat them, and what measures can we take to ensure that our children don’t develop allergies in the first place? In this episode, we’re joined by Willem M. de Vos, a professor of microbiology based at Wageningen University in the Netherlands. He tells us how the recent rise in births by caesarean section may be contributing to the increase in childhood allergies, how exposure to microbes in early life can have a profound effect on our immune systems, and how cutting-edge microbial treatments such as faecal transplants are showing promise in our fight against this growing health epidemic.

Chances are that when most of us think of spinosaurs our minds will turn to the hulking, predatory sail-backed dinosaur that famously took down a T. Rex in the Jurassic Park movies. But thanks to their highly fragmented fossil records, in the real world, our knowledge of these fascinating, ancient creatures is far from complete. Where did they live? How did they live? And what did they really look like? In today’s episode, we’re joined by David Hone, a palaeontologist based at Queen Mary University of London, and Mark P. Witton, a palaeontologist and paleoartist based at the University of Portsmouth, to talk about their latest book, Spinosaur Tales, The Biology and Ecology of the Spinosaurs. They tell us how palaeontologists piece together details of dinosaurs’ appearances and behaviours by painstakingly poring over fossil records, why we shouldn’t believe everything we see in the movies, and why there’s still so much to learn about these mysterious, and at times controversial, beasts.

How much control do we have over our actions and decisions? For most of us, it’s likely that the answer is that, of course, all of the choices we make are our own. But it’s long been argued by some scientists and philosophers that this isn’t the case at all. Could it be that the trajectories of our lives are largely already written into our biology, genes and neural circuitry before we’re even born? In this episode, we’re joined by Dr Hannah Critchlow, a neuroscientist and author based at the University of Cambridge and recipient of the 2026 Humanist Society’s Rosalind Franklin Medal. She explains how our personalities, beliefs and actions are deeply influenced by our ancestry, genes and upbringing, what’s happening in our brains when we make a decision, and how current research is showing that accepting our predispositions can likely help us all make the most of who we are.

In this episode, we’re joined by naturalist and author Amelia Thomas to discuss her latest book What Sheep Think About the Weather, How to Listen to What Animals Are Trying to Say. She tells us how the tone that’s innate in animal vocalisations may be the mother of all communication how dogs may have evolved their barks in order to express their wants and needs to us humans and how we can all enrich our lives by listening to the sounds that naturally occur around us.

It’s currently thought that around one billion people worldwide aren’t getting enough protein to meet their daily needs. Alongside this, it’s becoming increasingly clear that the large-scale farming of livestock and the overfishing of the Earth’s oceans to provide us with vital sources of protein are causing great harm to the environment. But could the production of more alternative protein sources, such as cultivated meat, plants like algae and duckweed and even insects, help provide us with a neat solution to both of these issues? As part of our four-part miniseries, Future of Food, we’re joined by a panel of three researchers based at The University of Sheffield: Professor of biomanufacturing Tuck Seng Wong, Professor of plant cell signalling Julie Gray and a Senior Lecturer based at the School of Chemical, Materials and Biological Engineering, Dr Kang Lan Tee. They tell us about the latest technological developments that are helping us to produce healthy, nutritious proteins in novel ways, how many of these methods can make much more efficient use of resources such as energy and water, and why perhaps many of us could benefit from being a little more open-minded when it comes to thinking about what we put on our plates.

According to the United Nations, around one-third of all the food currently produced across the planet is being lost or wasted, oftentimes before it even reaches our plates. As well as the loss of essential sources of nutrition needed to feed the global population, issues in food supply chains are using up other vital resources such as water, labour and energy. So, what can we do to ensure that as much food as possible makes it from farm to fork without being wasted? As part of our four-part miniseries, Future of Food, we’re joined by Dr Natalia Falagán, an Agricultural Engineer and Senior Lecturer in Food Science and Technology at Cranfield University. She explains the need for more joined-up thinking to help connect the different stages of our food production systems, the difference between use-by and best-before dates and tells us how growing something as simple as herbs in a kitchen window box can help us all deepen our relationships with the food we eat.

This episode was recorded on November 6th 2025. Artificial intelligence has been the movement of the moment in recent years. Since it burst to prominence in 2022, hundreds of millions of people have started using AI systems every day – for everything from writing essays to coding software, generating art and planning their lives. But with soaring valuations, constant hype, and growing concerns about how much these systems really understand, some experts and investors are starting to ask whether we’re heading for an AI bubble. One of them is Gary Marcus, a scientist, author, entrepreneur, and one of the AI industry’s most outspoken critics. Over the years, Gary has become a leading voice in debates about artificial intelligence, and many of his predictions about where the technology is heading have proven remarkably prescient. In this episode, Gary cuts through the noise and digs into hype vs reality, what current systems still can’t, and may never be able to do, and what a more reliable path forward might look like.

Along with their vast size and habit of jumping playfully out of the water, whales are renowned for their haunting melodic vocalisations. However, after decades of research, scientists still aren’t sure why these mysterious creatures sing their other-worldly songs. Could it be a form of sexual display? Maybe it’s a method of communication? Or is it possible that the giant marine mammals are using these plaintive moans as a form of echolocation? Behavioural neuroscientist and author of the book Why Whales Sing Prof Eduardo Mercado certainly thinks so. In this episode, he tells us how whale songs can last for as long as 40 hours and be heard up to 1,000km away, how, acoustically speaking, whale songs have more in common with bat vocalisations than birdsongs and how ocean noise created by increases in fishing and shipping activity may be wreaking havoc on whales’ ability to navigate the ocean depths.

Over the past several decades nutritional advice from doctors and expert researchers has largely relied on one-size-fits-all approach – eat five portions of fruit and veg a day, limit your intake of sugar and salt, stay away from overly fatty or processed foods as much as possible – but in recent times it has become clear that, while this is all good advice, the real-life picture is much more subtle. The latest research has revealed that the way we respond to the food we eat varies widely from person to person. As part of our four-part miniseries, Future of Food, we’re joined by Prof Sarah Berry, a nutritional scientist based at King’s College London and chef scientist at the ZOE. She tells us how the gathering of large-scale datasets on dietary habits is changing the way we think about nutritional science, how some of us are more sensitive to the negative effects of certain foods than others, and the key role that advances in technology are playing in the future of dietary research.

Throughout our lives we all go through several significant periods of change – puberty, young adulthood, middle age, retirement. Each comes with its own quirks and challenges, but perhaps one of the most underdiscussed of these stages is menopause. The lowering of hormone levels and eventual cessation of ovulation caused by menopause can affect women’s mental and physical health, performance in the workplace and even social life. So why is talking about it still considered so taboo? In this episode, we’re joined by Dr Saleyha Ashan, a journalist, emergency medicine doctor and researcher based at the University of Cambridge. She tells us what she’s learned from her own life experiences as a woman and medical doctor, the many, varied ways that menopause affects women’s physical and mental health and gives us advice that can help us all navigate this natural period in life more successfully.

Wikipedia. It needs almost no introduction. Few websites are more well-known, more commonly used and more foundational to the web as we know it than the online encyclopedia. This week, we’re joined by its founder, Jimmy Wales, to talk about how the platform has evolved over the past two decades, the challenges of maintaining trust and neutrality in an age of misinformation, and how AI could shape Wikipedia’s future. Jimmy also shares insights from his new book, The Seven Rules of Trust, exploring what it really takes to build credibility – and why it’s more important now than ever before.

Hippies, the Beatles, flower power, magic mushrooms, raves and festivals – that’s what most of us associate with psychedelics. But there is mounting evidence that these drugs could also be used medicinally, particularly to treat mental illnesses such as depression. In this episode, we speak to Prof David Nutt, a psychopharmacologist who has spent decades researching how drugs affect the brain. Now a professor at Imperial College London, David has published more than 500 research papers, eight government reports, and 40 books – including one called Psychedelics, in 2023. In this conversation, he explains how psychedelics affect the brain, how they alter people’s sense of self and perception of reality, and why they could revolutionise the future of mental health treatments. Please note that psychedelics are Class A drugs according to UK law. Anyone caught in possession of such substances can face up to seven years in prison, an unlimited fine, or both. Information and support for those affected by substance abuse can be found at bbc.co.uk/actionline. The following conversation specifically concerns psychedelics when used in a clinical context, given at low doses and under medical supervision. Please don’t try this at home.

The commonly held story goes that we all begin life as a single cell in our mother’s womb and go on from there to develop into fully formed adult human beings composed of cells of our own creation. However, recent research is showing that this isn’t quite the full picture. Not all of the cells in our bodies come from this single starting point. We are, in fact, all host to cells that have migrated from the bodies of other people – our mothers, grandmothers, siblings and even, in some cases, complete strangers. In this episode, we’re joined by science writer Lise Barnéoud to talk about her latest book Hidden Guests - Migrating Cells and How the New Science of Microchimerism Is Redefining Human Identity. She tells us how mothers and babies share cells across the placenta during pregnancy, how these cells make their homes within our organs and persist for our entire lives, and how this mysterious process led to a woman giving birth to the genetic children of her unborn twin sister.

Thanks to hundreds of years of scientific progress we now know, that like every other living thing on Earth, human beings are simply assemblages of atoms and molecules that evolved over eons through a series of complex, iterative processes. But somewhere along this long and meandering journey we developed consciousness – the deep sense of self-awareness that allows us to think, feel and even allows us to attempt to understand what’s going on in the Universe around us. In this episode, we’re joined by neuroscientist and author Dr Nikolay Kukushkin to talk about his latest book, One Hand Clapping – Unravelling the Mystery of the Human Mind. He tells us how this entire process all started millions of years ago through the interactions of atoms such as carbon and oxygen, how taking a bottom-up approach to the development of consciousness can help to explain how human beings became such complicated entities and how the advent of artificial intelligence may, or may not, influence the future evolution of our species.

Stars feel like a fundamental feature of the Universe – as essential as planets, galaxies and space itself. But since we know the Universe had a beginning (the Big Bang), there must also have been a first star. Before it, there was only darkness; after it, the cosmos as we know it began to take shape. Exactly what those first stars were like – and how they transformed everything that followed – remains one of astronomy’s great mysteries. It’s a mystery that astrophysicist Dr Emma Chapman has dedicated much of her career to solving. In this episode, Emma joins us to talk about her book First Light: Switching on the Stars at the Dawn of Time, recently updated to include discoveries from groundbreaking telescopes like the James Webb Space Telescope.
