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.

Recent UN data tells us that currently 670 million people around the world are going hungry. There's little doubt that food security is one of the most serious problems that the human race is facing. How have we reached this point of crisis and what solutions can we put in place to make sure everyone on the planet has enough nutritious food to eat without causing further harm to the environment? As part of our four-part miniseries, Future of Food, we're joined by Dr Dave Chandler, a crop researcher and agricultural scientist based at the University of Warwick. He tells us how current global food production practices are one of the most significant drivers of environmental damage and biodiversity loss, how climate change is threatening our ability to grow fresh produce to put on our plates and details some of the current thinking on how we can ensure the future of food production worldwide.

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.

Humanity is beautifully diverse. Some of that diversity is visible, but hidden beneath the surface, there is also a hidden web of genetic variation that collectively tells a story about how people have adapted to their environments, sometimes in weird and wonderful ways. In this episode, we speak to Prof. Herman Pontzer, an evolutionary anthropologist at Duke University, USA, and the author of Burn: the misunderstood science of metabolism, as well as his newest book, Adaptable: the surprising science of human diversity, which inspired this conversation. Herman tells us about how our genes can evolve over generations, how specific groups of humans have adapted to survive and thrive in different environments, and why understanding the science of diversity is so important for society as a whole.

Chances are that when most of us think about the notion of crime our minds turn to acts committed against an individual – be it theft, fraud or even physical assault. But every day ecological crimes are committed against the planet we all live on that often fly under the radar despite the significant, far-reaching effects they have on all of us. In this episode, we're joined by criminal psychologist and bestselling author, Dr Julia Shaw to talk about her latest book, Green Crime – Inside the Minds of the People Destroying the Planet, and How to Stop Them. She breaks down the factors that drive individuals and organisations to commit acts that are damaging to the environment and explains how understanding the psychology that underpins these acts can help us to keep our planet healthy for generations to come.

Be it a cold, drafty room in a creaky old country house or a still, quiet forest on a dark night, chances are that at one point or another we'll all have entered an environment that for some reason made us feel uneasy. But what exactly makes a certain place or situation feel so creepy, and why do we get these feelings in the first place? In this episode, we're joined by psychologist and magician Prof Richard Wiseman to talk about his work as a scientist who investigates the psychology behind paranormal phenomena. He tells us how ghostly experiences may actually have evolved to help keep us away from dangerous environments, how our brains are primed to see faces that aren't really there, and how the state of consciousness that exists between waking and sleeping can lead us to feel the presence of threatening entities lurking in our bedrooms.

Chances are when we're treated with medicines in hospital or pick up our prescriptions at the pharmacy, we don't give much thought about how the drugs that are so vital for our health and wellbeing came to be. The fact is the journey that a new medicine takes from its beginnings in the laboratory to finally being administered to patients can be long and arduous. It typically takes the work of countless scientists, researchers and technologists toiling away behind the scenes for decades and is often fraught with failure. So exactly how does a new drug make the grade? In this episode, we're joined by oncologist and drug researcher Dr William Pao to talk about his latest book, Breakthrough – The Quest for Life-Changing Medicines. He tells us how fundamental academic scientific lays down the bedrock for the development of a new drug, runs us through the vital importance that clinical trials play in the whole drug development process, and tells us the fascinating story of how the common everyday drug paracetamol was discovered by accident.

Is our planet under threat from the depths of space? In this episode, we talk to solar physicist Dr Ryan French. Normally, Ryan is busy unravelling the mysteries of our Sun, but today we'll be delving into a slightly darker topic – the many risks posed to our delicate planet from space. In his recent book, "Space Hazards: Asteroids, solar flares and cosmic threats”, Ryan covers all the many dangers our planet faces from space rocks, the Sun and the farthest reaches of the Universe. We run through some of the most pressing threats and find out just how worried we should be. Learn more about your ad choices. Visit podcastchoices.com/adchoices

Many of us treat our pet dogs or cats with the same love and attention that with give to our human babies, some of us give our cars or other prized possessions human names and may even, at times, talk to them. This is known as anthropomorphism – the tendency within many of us to assign human qualities to non-human animals and even inanimate objects. In this episode, we're joined by Dr Justin Gregg to talk about his latest book, Human-ish – How Anthropomorphism Makes Us Smart, Weird and Delusional. He tells us how we've bred our pets to look and behave in more and more human-like ways, the benefits we can all gain from attributing human-like qualities to inanimate objects such as cars or musicalminstruments, and how AI chatbots are expanding the phenomenon of anthropomorphism further than ever before.

It's a little-known fact that bats are one of the most successful animals on Earth, with almost 1,500 different species currently identified. Their agility in flight and prowess as hunters, wide-ranging diversity in size and behaviour and ability to adapt to almost any environment have allowed them to conquer almost every corner of the globe. But despite their success, many species of bats are now under threat. In this episode, we're joined by ecologist and neurobiologist Prof Yossi Yuval to talk about his latest book, The Genius Bat – Understanding our Most Mysterious Mammal. He gives us a breakdown of bats' sophisticated ability to ‘see' the world using sound, tells us how despite their reputation as terrifying blood-thirsty predators, vampire bats have highly developed social networks and will even share their meals with other members of their roosts, and also explains how the loss of bats could have a huge effect on the ecosystems in which they live.

Thanks to their comical waddle-like way of walking, striking tuxedo-patterned plumage or graceful ability to seemingly ‘fly' beneath the water, penguins are without doubt one of the planet's most instantly recognisable animals. But the fact is that they are also one of its most endangered species of bird. In this episode, we're joined by Dr Peter Fretwell, lead scientist at the British Antarctic Survey, to talk about his latest book The Penguin Book of Penguins – An Expert's Guide to the World's Most Beloved Bird. He tells us how, despite popular belief, penguins are found all over the globe, not just in Antarctica, why exactly they have such a comical way of walking and the actions we need to take if we want to save these charismatic birds from extinction.

Relatively speaking neuroscience and psychology are young fields of scientific research that only really got going over the last hundred years or so. However, during this time several stubborn myths have arisen that, zombie-like, just don't seem to go away. In this episode, we speak to neuroscientist, best-selling author and long-time BBC Science Focus contributor Dr Dean Burnett. He tells us how much of our brain we really use, explains whether polygraphs can really tell if we're lying, and explains the real difference between our left and right brains.

When it comes to climate change, we often think of tipping points as having a huge negative effect. Be it the loss of ice sheets in the Arctic, the deforestation of the Amazon rain forest or the alteration of ocean currents, scientists have identified several key systems on the Earth that will be impossible to reverse if they cross a critical threshold. But if we look at the situation from the opposite side, there are also several positive tipping points that, given the correct momentum, can potentially halt the crisis the planet is facing. In this episode, we're joined by Prof Tim Lenton, chair in Climate Change and Earth System Science at the University of Exeter, to talk about his latest book Positive Tipping Points – How to Fix the Climate Crisis. He tells us how the pop group A-ha helped Norway to lead the way in the adoption of electric vehicles, how government mandates can act as powerful amplifiers to get us closer to these vital climate tipping points, and how each positive tipping point can feed into another to push us closer to a greener future.

From Lewis Carrol's mysterious grinning Cheshire Cat and Jim Davis's lazy, lasagne-loving comic strip tabby Garfield to the depictions of big cats found in palaeolithic cave art and the ancient Egyptian's practice of worshipping cat-like deities, it's clear we humans have had a long-standing fascination with felines. But how did this obsession with these charismatic animals begin? In this episode, we're joined by Jerry D Moore, a professor of anthropology at California State University, Dominguez Hills, to talk about his latest book Cat Tales: A History – How We Learned to Live with Them… He tells us how ancient cultures feared and revered the big cats they shared their land with thanks to their prowess as apex predators, how human's development of agriculture and the storage of grain gave wild cats a reliable hunting ground in which to catch rodents, and how the domestic house cats of today may have chosen to live with us and much as we chose to live with them.

Despite being a land-based species, the fact is that we humans live on a planet that is largely covered by oceans. The oceans play a key role in regulating the Earth's climate and provide us with many of the resources essential for our continued survival – even down to the oxygen we breathe. The sad truth is our oceans aren't in good shape. But there is still hope. With directed effort we can all help to preserve this vital resource and improve the health of the planet and all who live on it. In this episode, we catch up with oceanographer, environmentalist and grandson of the legendary ocean explorer and innovator Jacques Cousteau, Philippe Cousteau Jr. He breaks down the huge importance the oceans have on the health of the planet, explains how taking positive environmental action can benefit us both culturally and economically and how educating the next generation is key to safeguarding the future of the planet.

The most commonly held narrative states that we're all ultimately responsible for our own health and wellbeing. While there's undoubtedly truth in this idea, the bigger picture shows that the societies we live in and the policies shaped by our governments also play a huge role in our quality of life and longevity. In this episode, we're joined by Devi Sridhar, professor of global public health based at the University of Edinburgh, about her latest book, How Not to Die (Too Soon) – The Lies We've Been Sold and the Policies That Can Save Us. She explains how the key to longevity begins with education, discusses the lessons we can learn from some of the world's longest-lived populations, and outlines the positive societal changes governments can implement to help us all live longer, healthier lives.

It's estimated that as many as one in five of the world's population are neurodivergent. Be it ADHD, autism or dyslexia, these differences in brain function can make everyday life more difficult for many. But maybe the natural world can provide some much-needed relief. In this episode, we speak to naturalist and author Joe Harkness about his latest book Neurodivergent by Nature – Why Biodiversity Needs Neurodiversity. He tells us why many neurodivergent people don't receive an accurate diagnosis until later in life, why many neurodivergent people are attracted to careers in conservation and how getting out in natural environments can help us all to relax and feel safe.

The luteal phase of the menstrual cycle has a really bad reputation. It's known for premenstrual syndrome, or PMS, when many menstruating people experience low mood, bloating, food cravings and sluggishness before their period arrives. In stark contrast, we think of earlier phases in the cycle as times when we feel energetic, motivated and self-confident. In this episode, we speak to Dr Sarah Hill, an evolutionary psychologist whose research focuses on women, relationships and health, and the author of This is Your Brain on Birth Control and her upcoming title, The Period Brain. She tells us what happens to the body and brain during the luteal phase, why so many of us experience unpleasant symptoms, and some little things we can do to feel our best.

We're no longer living in a world before climate change. Its impacts – from rising sea levels to more extreme weather – are already upon us, and will almost certainly get worse before they get better. But beyond cutting our emissions as fast as possible, what do we need to do to survive, and hopefully thrive, in this new world?  Today's guest, researcher and author Susannah Fisher, joins us to explore that question. In her new book Sink or Swim, she lays out two possible futures: one where we fail to adapt and face the mounting chaos, and another where we make the hard choices needed to live in a hotter world. Which one of these we end up with, she says, is up to us. Learn more about your ad choices. Visit podcastchoices.com/adchoices

Humans' unique ability to communicate through complex systems of language is one of the key attributes that separates us from the rest of the animal kingdom. But how did this complex behaviour arise? In her latest book, The Origin of Language – How We Learned to Speak and Why, evolutionary biologist Madeleine Beekman argues that our ability to speak arose due to the need to take care of our children. She tells us how early human's anatomy changed dramatically when our ancestors came down from the tress and began walking on two legs, how a quirk of genetics allowed humans to develop such large brains that aided the development of language, and why human's slow development from helpless infants to functioning members of society gave rise to the need for in-group cooperation and complex modes of communication.

For thousands of years humans have looked out into the night sky and pondered on the mysteries of the vast cosmos that we find ourselves part of. From Copernicus' discovery that the Earth revolves around the Sun to Einstein's revelation that gravity is the result of the curvature of spacetime, we've learned much about how the universe operates. But we're still only scratching the surface. In this episode, we speak to Marcus Chown, an award-winning science writer and broadcaster and long-time contributor to BBC Science Focus. He explains why pinning down the nature of dark matter and dark energy has eluded us for so long, why we can't get gravity to agree with the three other forces of nature, and discusses the possibility of the existence of multiple universes.

If most of us were asked what we thought was meant by the word ‘technology' chances are the first thing that would come to mind are inventions such as cars, medicine and computers. But economist and author David McWilliams would argue these are all physical technologies and that there's also a whole world of social technologies out there that have shaped human progress in a similarly profound way that most of us are largely unaware of. Chief amongst these, he says, is the invention of money. In this episode, we speak to David about his latest book Money – A Story of Humanity. He tells us how the very reason that money has any value at all is based on our collective belief and trust in it as a concept, how money was much more deeply involved in turning points in human history than first meets the eye, and we need to see our relationship with money as an evolutionary process that progresses much like natural selection.

Dementia doesn't have to be terrifying. We tend to think of neurocognitive decline as something to be feared and avoided, but as the population ages, more and more of us are being diagnosed with dementia – so it might be helpful to know more about it. In this episode, we speak to Dr Sabina Brennan, a neuroscientist, psychologist, bestselling author and host of the Super Brain podcast. Her new book, Still Me: a neuroscientist's guide to caring for someone with dementia, offers practical advice for approaching dementia care in a loving and brain-healthy way. Sabina tells us about her own experiences caring for her mother, the different ways neurocognitive decline can manifest itself, and how to find joy and fulfilment alongside dementia.

Every day we all breathe in thousands of litres of air, it is, of course essential for our continued existence. But did you know that the air that surrounds us is filled with a thriving colony of life itself? This is known as the aerobiome – a population of thousands of species of bacteria, fungi and even potentially lethal viruses such as SARS-CoV-2. In this episode, we speak to science journalist and author Carl Zimmer about his latest book Air-Borne – The Hidden History of the Life We Breathe. He runs us through the fascinating history of aerobiology, outlines the key role the field played in developing the germ theory of disease, and explains how even clouds are filled with life.

Rapid advances in technology over the past several decades have impacted almost every area of our lives. It could be argued that innovations in medicine and healthcare are one of technology's biggest success stories. However, many of us are still living in poor health, particularly in our later years. Can technology once again come to our rescue and help us to not only live longer lives but to help us to stay healthier for longer? In this episode, we speak to technology journalist and author Lara Lewington about her latest book Hacking Humanity: How Technology Can Save Your Health and Your Life. She tells us how me may soon all have a ‘digital twin' containing all of the data about our bodies and health that can be used to test the efficacy of drugs before we take them, the increasing role robotics can play in the operating theatre and the huge impact that the AI revolution can have on the future of healthcare.

Why do some people become radicalised, while others remain resistant to extreme ideas? What makes one mind more vulnerable to harsh doctrines than another? In a world saturated with competing ideologies, it's tempting to blame it on chance or circumstance. But in her compelling new book, The Ideological Brain, political neuroscientist Leor Zmigrod uncovers a deeper truth: our susceptibility to extremism is shaped by the very architecture of our minds, down to the cellular and genetic level. She explores how our cognitive traits influence ideological thinking, and crucially, why we're not locked into any one path.

Be it at school or in the workplace, many of us are under more and more pressure to work harder for longer to ensure that we're performing at our best. But the latest neuroscience research is discovering that we may all have this idea entirely the wrong way around. In this episode, we speak to neuroscientist Dr Joseph Jebelli to talk about his latest book The Brain at Rest: Why Doing Nothing Can Change Your Life. He tells us how overwork is leading to almost 750,000 deaths a year globally, how taking a few minutes to pause and do nothing every now and then can switch on the powerful effect of our brains' default network, and how simply allowing our minds to wander from time to time can help us to be more creative and more productive.

Currently, 60 per cent of people in the UK are overweight or obese. It's likely that many of us would like to drop a few pounds if possible but with so much information on diet and weight loss available separating facts from myths can be something of a minefield. In this episode, we speak to Prof Giles Yeo, a geneticist and obesity expert based at the University of Cambridge. He tells us exactly how our bodies extract calories from the food we eat, the real effect that exercise has on our weight, and how the reward pathways in our brains are linked to our appetites.

How do our brains help us build up a picture of the world around us? It's a question that has both beguiled and fascinated scientists for centuries. The latest thinking suggests that the brain acts like a scientist that builds up a database of previous observations and experiences and uses this to make sense of the world around us. In this episode, we speak to Daniel Yon, an experimental psychologist based at Birkbeck, University of London to talk about his latest book A Trick of the Mind: How the Brain Invents Your Reality. He tells us about the intimate link between our brains and senses, how our brains create our sense of self and make judgements about others, and how our brains come up with new theories and ideas.

Humans are enthralled by stories about murder. And the mysteries we tell these days – like in the Glass Onion films or TV shows like The Residence – often follow a blueprint set by the iconic Agatha Christie. It turns out, Christie knew a whole lot about science. In this episode, we speak to Dr Kathryn Harkup, a chemist who writes about the science behind famous works of literature. Her newest book, V is for Venom: Agatha Christie's Chemicals of Death, is her sequel to A is for Arsenic: The Poisons of Agatha Christie, exploring Christie's expert use of dark chemistry. She tells us about some of the poisons Christie used in her books – the brutal, the medicinal and the obscure – revealing Christie's extensive chemical knowledge.

It's a little-known fact that we all have two long networks of nerves that run down either side of our necks that pass signals from our brains to all of the organs in our bodies. This is known as the vagus nerve, and cutting-edge research is now uncovering how stimulating this vital part of our anatomy can help us combat a whole range of damaging health conditions. In this episode, we speak to neurosurgeon and researcher Dr Kevin J Tracey about his latest book The Great Nerve: The New Science of the Vagus Nerve and How to Harness its Healing Reflexes. He tells us how this nerve network acts as a vital conduit for communication between our brains and organs, talks us through the exciting new therapies being developed using electronic implants that stimulate the vagus nerve, and why we're only just scratching the surface of the therapeutic potential of this understudied part of our bodies.
