  • How whales may be using their haunting songs as a navigation system

    How whales may be using their haunting songs as a navigation system
    Nov 7 2025
    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.

  • Future of Food: How personalised nutrition is transforming our understanding of diet and health

    Future of Food: How personalised nutrition is transforming our understanding of diet and health
    Nov 3 2025
    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.

  • What we all need to know about menopause

    What we all need to know about menopause
    Oct 31 2025
    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 founder Jimmy Wales on what AI and Elon Musk mean for the site's future
    Oct 27 2025
    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.

  • How psychedelics could kickstart the next mental health revolution

    How psychedelics could kickstart the next mental health revolution
    Oct 23 2025
    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.

  • How our bodies are host to mysterious cells that came from other people

    How our bodies are host to mysterious cells that came from other people
    Oct 19 2025
    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.

  • How human consciousness emerged from the fundamental processes of nature

    How human consciousness emerged from the fundamental processes of nature
    Oct 16 2025
    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.
