  • Why understanding how time works is the biggest mystery in science

    Why understanding how time works is the biggest mystery in science
    Sep 3 2026
    When most of us think about time our minds likely turn to thoughts of the second hand that ticks around a clock, or maybe the occasions we’ve been late to catch a bus. But if we stop to think about what time actually is things quickly get more subtle and complicated. Does time only exist in our minds as a psychological illusion, does it really only run forwards and not backwards, and how close is modern physics to helping us to figure out its true nature? In this episode we’re joined by physicist, best-selling author and BBC presenter Prof Jim Al-Khalili to talk about his latest book, On Time – The Physics That Makes the Universe Tick. He tells us how thinkers going back as far as ancient Greece have struggled to define what time really is and how it works, how Einstein’s theories tell us that time can run at different rates in different circumstances, and how understanding its true nature maybe key in our search for a theory of everything.

  • How forensic scientists gather vital evidence to solve crimes

    How forensic scientists gather vital evidence to solve crimes
    Aug 30 2026
    Whenever a crime is committed, tiny traces of evidence are left behind at the scene, which, if pieced together correctly, can tell us exactly what happened, when it happened and who was responsible. This is the job of forensic scientists. But how exactly does this process work, how accurate are the portrayals of crime scene investigators we see on film and TV, and what happens if when mistakes are made? In this episode we’re joined by science journalist and author Sanjukta Mondal, to talk about her latest book, Forensic Science. She talks through the fascinating history of forensic science, explains how we all leave traces of our presence wherever we go, and tells us about some of the common myths and cliches we often see in TV crime shows.

  • Why the most extreme El Niño event for a century is on its way

    Why the most extreme El Niño event for a century is on its way
    Aug 27 2026
    Every several years, the surface temperatures of the Pacific Ocean rise, triggering a climate event that has a domino effect on weather patterns across the globe. This is known as El Niño – and this year, meteorologists predict we’re in for a big one. But how exactly do these events occur, how big an effect is climate change having on their frequency and impact, and what can we expect to see in the future? In this episode, we’re joined by Prof Adam Scaife, head of long-range prediction at the Met Office in the UK. He tells us how El Niño events arise in the Pacific Ocean and spread across the globe, how they’ve been occurring cyclically for thousands of years, and why the event this year is forecasted to be the most extreme in decades.

  • The secret world hidden in the ground below us

    The secret world hidden in the ground below us
    Aug 23 2026
    Though we’re often not aware of it, the ground beneath our feet is teeming with an abundance of life and activity – from the complex networks of fungi and tangled roots put down deep into the Earth by the plants that live on its surface to the staggering variety of organisms that make their homes in the damp and darkness of the soil. This vast, fascinating ecosystem is vital for the health of the planet but remains largely unstudied. In this episode we’re joined by Dr Frank Ashwood, a lecturer in ecology and entomology at Lincoln University, New Zealand, to talk about his latest book, The World Beneath Our Feet – The Hidden Life of Soil and Why it Matters to us All. He tells us how more than half of the planet’s biodiversity is found living within soil, how the animals that live underground have inspired innovations in medicine and technology and how we may be able to use our knowledge of soil biology on Earth to help us in our quest to establish colonies on other planets.

  • The truth about the Nazi fascination with alternative medicine

    The truth about the Nazi fascination with alternative medicine
    Aug 20 2026
    It’s widely documented that during the time of the Third Reich, the Nazi Party employed a legion of scientists to aid them in their goals of military superiority and ethnic cleansing – particularly in their pursuit of eugenics and development of cruel nerve agents and chemical weapons. It’s far less known that Heinrich Himmler, one of the primary architects of the Holocaust, considered himself to be a talented scientist and harboured a long-held, and frequently bizarre, fascination with quackery and alternative medicine. In this episode, we’re joined by physician, researcher, and author Edzard Ernst to talk about his latest book, The Leopard Lily Project – A Story of Nazi Pseudoscience. He recounts the story of a sinister plot to sterilise large swathes of the population using a herbal folk remedy, how this project arose from the wider ideology of the Nazi Party, and explains why, ultimately, the whole enterprise was doomed to failure from its inception.

  • What we’re getting wrong about narcissists

    What we’re getting wrong about narcissists
    Aug 16 2026
    Oftentimes in popular culture we’ll hear the term narcissist used to describe a person who has an inflated opinion of themselves, a big ego or someone who tends to overestimate their own abilities. However, in psychology, narcissistic personality disorder is defined as a diagnosable mental health condition that can cause just as many issues for those living with it as it does for those around them. In this episode we’re joined by neuroscientist and best-selling author Dr Dean Burnett, to talk about many of the misunderstandings that surround narcissistic personality disorder. He explains some of potential triggers that can lead to the development of this complex condition, why it’s innately incredibly difficult to diagnose, and how, paradoxically, many narcissists can suffer from profound feelings of self-loathing.

  • How to harness your brain’s underused superpowers

    How to harness your brain’s underused superpowers
    Aug 9 2026
    For a large proportion of our lives, our brains seemingly work on autopilot – the many processes the brain controls hum away behind the scenes, helping us to carry out our daily tasks. But in certain scenarios, our attention takes over, giving more conscious control of our actions. These processes, such as memory, planning and our emotional responses to the situations we find ourselves in, are known as executive functions. But how exactly do they work and is there anything we can do to train them to perform more effectively? In this episode we’re joined by the neuroscientist and author Dr Adrian Owen, to talk about his latest book, Think Before You Think – Understanding Your Brain’s Mission Control. He shares his insights into how our brains operate when we’re confronted by different situations, points out some of the pitfalls built into the way we observe and respond to the world, and explains how we can all benefit from paying more attention to why we think and act in the way we do.
