  • Why the liver is the body’s most misunderstood organ

    Why the liver is the body’s most misunderstood organ
    Jul 5 2026
    Most of us think about the liver as simply being the body’s filtration system that acts as a sponge that removes toxins from our bloodstreams. But the truth is it performs many more functions that are vital for our health such as acting as the primary organ in regulating our metabolisms, storing essential nutrients our bodies can draw from in times of need, and even producing proteins that help our blood to clot when we’re injured. However, changes in our lifestyles over the past several decades are leading to an alarming rise in the prevalence of damage and disease to this essential organ. In this episode, we’re joined by Dr Quin Wills, a researcher and CEO of the biotech company Ochre Bio, who specialises in developing innovative new treatments to combat liver disease. He talks us through the many functions the liver performs in our bodies, explains some of the most common causes of the rise in chronic liver disease and looks forward to the future to detail some of the cutting-edge treatments that may be on the horizon to combat this growing issue.

  • Why this common women’s health condition is so misunderstood

    Why this common women’s health condition is so misunderstood
    Jul 2 2026
    Despite affecting as many as 80 per cent of women by the age of 50, fibroids, lumps of tissue that grow in or around the womb, are not commonly discussed outside of specialist doctors’ offices. However, they can cause a whole host of health issues, such as heavy or painful periods, poor bladder control, chronic constipation, and even affect fertility and complicate childbirth. In this episode, we’re joined by Dr Michelle Griffin, a women's health expert, author and former BBC Science Focus columnist, to talk about her latest book, Fibroids – Everything You Need to Know, From Symptoms to Diagnosis and Beyond. She tells us how the location of fibroids determines the specific symptoms and complications associated with them; the role hormones play in their development and growth and talks us through some of the latest developments in treating this common but overlooked condition.

  • The miraculous healing ability of our brains

    The miraculous healing ability of our brains
    Jun 28 2026
    It was previously thought that once our brains suffer an injury due to stroke or trauma, the potential for recovery was severely limited. But recent developments in medicine have proven that this isn’t the case; our brains are, in fact, capable of miraculous acts of healing. This is thanks to a process known as neuroplasticity, a concept that’s changing the way that medical practitioners are helping patients suffering from brain injuries regain their health. In this episode, we’re joined by neurologist and author Orlando Swayne to talk about his latest book, How to Use a Fork – Stories of Mending the Broken Brain. He tells us what happens in our brains following injury, how learning new skills can change the structure of our brains, and how we can use this process to help people recover from strokes, aneurysms and other debilitating brain injuries.

  • How parasites play a vital role as caretakers of Earth’s ecosystems

    How parasites play a vital role as caretakers of Earth’s ecosystems
    Jun 25 2026
    When most of us think of parasites, our minds will likely turn to thoughts of the various icky creatures that can invade our bodies, make their homes there and end up making us ill. But the truth is that parasites make up a hugely significant part of all life on Earth and bring many benefits to the organisms they live in or alongside and the wider ecosystems they are a part of. As part of our Nature’s Unsung Heroes miniseries, we’re joined by Timothy Brown, a researcher based at the University of Leeds and member of the IUCN Parasite Specialist Group who works on the conservation of parasite diversity, to talk about the many ways in which parasites influence life on Earth. He tells us how our own bodies are host to trillions of different beneficial organisms, the key role parasites play in managing the balance of the animal life in the ecosystems they are part of and talks us through the most recent ideas researchers are working on to preserve these overlooked, but ecologically vital creatures.

  • How to keep your body younger for longer

    How to keep your body younger for longer
    Jun 21 2026
    When it comes to the effects of ageing on our bodies, there are many more factors at play than simply the number of years we’ve been alive. It turns out, that for some people, there is a huge gap between their chronological age and their biological age – the scientific measure of how well our cells, tissues and organs are functioning compared to the global average. But what are the main drivers of this difference, and what can we do to keep our bodies younger and healthier for longer? In this episode, we’re joined by ageing and longevity expert and research director at Inserm in France, Jean-Marc Lemaitre to talk about his latest book, Choose Your Age – Unlocking the Cellular Science of Longevity. He talks us through the many factors that lead to some of us ageing more quickly than others, tells us what researchers can learn from how the world’s centenarians live their lives, and explains why we still don’t know what the limit for the human lifespan could be.

  • Why wasps are one of the planet’s most misunderstood insects

    Why wasps are one of the planet’s most misunderstood insects
    Jun 18 2026
    The truth is, when most of us think of wasps, our minds will likely go to memories of irritating winged pests landing in our drinks when we’re trying to have a nice summer picnic or perhaps one of the times we got a nasty sting when we were out playing in the park as children. It’s fair to say wasps have a pretty bad rap. But if we look more closely, it soon becomes clear that most of us are getting these fascinating insects entirely wrong. As part of our Nature’s Unsung Heroes miniseries, we’re joined by BBC broadcaster, author and entomologist based at the University of Gloucestershire Prof Adam Hart to talk about the many benefits wasps bring to the ecosystems they live in. He tells us how wasps act as the wardens or guardians of our gardens and agricultural land by keeping pests under control, how they act as essential pollinators that help the ecosystems they live in thrive, and how they act as one of the natural world’s most sophisticated architects and engineers.

  • Why you probably don’t need to be taking dietary supplements

    Why you probably don’t need to be taking dietary supplements
    Jun 14 2026
    These days the supplement industry is booming – supermarket shelves are stacked high with all manner of pills and powders claiming to do everything from helping us to live longer or improving our digestive health to boosting our energy levels or even improving our ability to concentrate and focus. How have we reached this point, why do many of us feel our diets aren’t giving us everything we need to stay healthy and productive, and do these supplements live up to the bold claims that many manufacturers make for them? In this episode, we’re joined by dietician and author Josie Porter to talk about her latest book, How Not to Take Supplements – A Dietician’s Guide to Thriving on Real Food. She tells us how our busy lifestyles are leading more of us to turn to dietary supplements, talks us through the rise in the consumption of protein powders and meal replacement drinks, and explains how, underlying health conditions aside, we can all get everything our bodies need to stay healthy by eating a balanced diet.

  • Why this tiny organism is essential for the health of the planet

    Why this tiny organism is essential for the health of the planet
    Jun 11 2026
    Although it often goes unnoticed, plankton is the most abundant form of life in Earth’s oceans, making up 95 per cent of all oceanic biomass. These tiny organisms are responsible for generating around half of the planet’s oxygen, play a vital role in the oceans’ food chains and were around for millions of years before we humans came onto the scene. Simply put, without plankton, the world would be a very different place. As part of our Nature's Unsung Heroes miniseries, we’re joined by senior advisor to the United Nations on oceans Vincent Doumeizel to talk about his latest book, The Power of Plankton – How Plankton Made Life on Earth Possible and Why It’s Key to Our Future. He tells us how these often-ignored organisms played an essential part in the evolution of life on Earth, tells us the many ways plankton acts as the caretaker of the entire planet, and makes a passionate case for why we should be paying more attention to these fascinating, ancient organisms.
