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.

There’s little doubt that music is an integral part of what it means to be human. But how did it first arise, how did musical instruments and compositions become ever more sophisticated and why does listening to or playing music bring us so much joy? In this episode, we speak to science writer and music producer David Darling about his latest book A Perfect Harmony: Music, Mathematics and Science. He tells us how the oldest pitched musical instrument found so far is thought to be more than 40,000 years old, the role music has played in the evolution of human culture, and what the impact AI-generated music may have on the work of human musicians and composers in the near future.

It’s commonly believed that the arts and the sciences have little in common with each other. The distinction that’s most frequently made is that the arts are creative in nature whereas the sciences are logical. But this couldn’t be further from the truth. In this episode, we catch up with mathematician and author Marcus du Sautoy to talk about his latest book Blueprints: How mathematics shapes creativity. He tells us how, fundamentally, mathematics is the study of patterns, structure and symmetry, how these patterns are found everywhere in music, visual art and architecture, and why we should be teaching students how to spot them in their everyday lives.

It’s a scene many of us will have experienced: we’re at the cinema, the lights go down, the film begins and then suddenly the person behind us starts rustling a packet of sweets or noisily chomping on popcorn. For most of us this is merely an annoyance and after a while we’re able to tune the sounds out and concentrate on enjoying the cinematic experience. But for some, it can be unbearable and engender feelings of distress, anger and even panic. These people are experiencing misophonia. In this episode, we catch up with Dr Jane Gregory, a clinical psychologist and author of the book Sounds Like Misophonia: How to Stop Small Noises from Causing Extreme Reactions.

Addiction can be devastating not only for the addict themselves, but also for their loved ones and anyone around them. But what causes it, and how should we treat it? According to Dr Elias Dakwar, a psychologist based at Colombia University, New York, we should be looking beyond the commonly held brain disease model of addiction and deeper into its philosophical or existential underpinnings. In this episode, we speak to Dr Dakwar about the years of clinical research he outlines in his latest book The Captive Imagination: Addiction, reality and our search for meaning. He tells us about his thinking on how addiction stems from our desire for happiness and feelings of meaningless, how it fits in with the notion of personal freedom, and details some of his work with clinical patients in treating addiction in new ways.

Like it or not, Earth won’t be our home forever. Whether it’s climate collapse, nuclear war, or the slow death of the Sun, life on this planet is on borrowed time. So, what happens next? If we’re serious about avoiding extinction, we’ll need to look not just beyond Earth – but far beyond our Solar System. Our guest today believes we not only can do that, but that we must. Christopher Mason is a Professor of Physiology and Biophysics at Weill Cornell Medicine and author of The Next 500 Years: Engineering Life to Reach New Worlds. In the book, he argues that as the only species aware of life’s inevitable end, we have a moral duty to preserve it – not just our own, but all life on Earth. To do that, we’ll need to radically rethink what it means to be human. Because as things stand, our bodies are far too fragile to survive the journey. Chris lays out an ambitious 500-year plan to reengineer human biology, making us more resilient to space travel and alien environments — and he maps out how we might go about seeding life across the stars. So, is humanity ready to become an interstellar species? And where on Earth – or off it – do we begin? Learn more about your ad choices. Visit podcastchoices.com/adchoices

There’s no doubt new advances in science and technology are having a huge impact on the way we live our lives these days.

In this episode we speak to Professor Sir Munir Pirmohamed, David Weatherall Chair in Medicine at the University of Liverpool, NHS Chair of Pharmacogenetics, and a consultant physician at the Royal Liverpool University Hospital. He tells us how advances in medical techniques such as genetic screening and a focus on patients’ differing reactions to treatment can go beyond a one-drug-fits-all approach to healthcare and even treat diseases before symptoms appear.
