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.

Although we can’t see them with the naked eye, the Earth is populated by vast numbers of tiny living organisms such as bacteria, fungi and viruses. Collectively, these organisms are known as microbes, and they have existed on the planet for billions of years. But what role did they play in the origin of complex life, how have they stuck around for so long and how can they help us shape a healthier future for the planet? In this episode, we speak to science writer and author Peter Forbes about his latest book Thinking Small and Large: How Microbes Made and Can Save Our World. He tells us the role microbes played in the evolution of multicellular life, their deep importance to the world’s ecosystems and how they may help us to produce the food, fuel and materials of the future.

Be it a pair of wolves that mate for life, a pod of female dolphins that hunt together, or a large colony of honeybees all working together in a hive, the natural world is filled with relationships of all kinds. But some relationships run deeper than others, even to the extent that certain species literally make their homes inside the bodies of others. This is an example of a symbiotic relationship – a long-term bond that exists between organisms of different species. In this episode, we speak to science writer Sophie Pavelle about her new book To Have or to Hold: Nature’s Hidden Relationships. She tells us how far from being rare, symbiotic relationships occur practically everywhere in the natural world, how they come in a dizzying array of different forms, and how the fine balance underpinning these relationships that has formed over thousands of years is coming under threat from human activity and climate change.

Everywhere we look we’re surrounded by materials of all kinds – from the fabrics we use to make our clothing, to the bricks and mortar we use to build our homes and places of work, to the complex transistors and circuits we use to build our digital devices. Life as we known it simply wouldn’t be possible without them. But what will the materials of the future look like? In this episode, we catch up with Mark Miodownik, professor of materials and society based at University College London, best-selling author and veteran presenter of many BBC television and radio science documentaries. He tells us how the advent of materials such as paper, bronze and ceramics transformed early humans into a truly technological species, how nano-machines are already showing promising results in several areas of medicine, and how we may one day be living in buildings that can generate their own electricity and repair themselves.

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

Every day we’re presented with hundreds if not thousands of decisions: What do we want for breakfast? Should we call our mothers or spend time with our friends? Should we go out for a workout or watch TV and eat snacks? Of course, some of the choices we make are more significant than others and can have huge impacts on our lives. But what do these decisions say about us and how can we try to make better choices? In this episode, we catch up with neuroscientist and professor of communication at the University of Pennsylvania Emily Falk to talk about her latest book What We Value: The Neuroscience of Choice and Change. She tells us how certain regions of our brains are involved in the many decisions we make, how we weigh up short and long-term rewards, and how we can all make more thoughtful choices that align with our goals if we just make a few tweaks to our behaviour.

The ocean covers more than 70 per cent of our planet’s surface. Thanks to its ability to absorb the excess carbon and heat generated by climate change, its potential to generate clean energy and the bountiful source of food it provides to both humans and animals, there’s little doubt the ocean is vital for the continued survival of the human race and of the planet itself. But all is not well. Ocean temperatures are climbing, coastal water levels are rising, and extreme weather events are becoming more and more common. In this episode we speak to special advisor on ocean issues to the United Nations Sturla Henriksen about his latest book The Ocean: How It Has Formed Our World – And Will Shape Our Destiny. He tells us about the many challenges we are facing to keep the ocean healthy and why we need to take a more holistic approach to combat them. Learn more about your ad choices.

We all experience distressing or intrusive thoughts at some point in our lives but for around two to three per cent of us these can be incredibly difficult to ignore and can begin to have a significant debilitating effect on our lives. Clinically this is known as obsessive compulsive disorder or OCD – a condition that many of us will have heard of but few understand. In this episode, we speak to Dr Marjan Biria, a psychologist and neuroscientist based at University College London. She tells us about some common obsessions and compulsions experienced by those with OCD, why thoughts are not actions and why people who say they are ‘a little bit OCD’ because they like cleanliness or order are significantly misunderstanding the condition.

Despite decades of international climate summits, the ongoing work of various campaign groups and open letters signed by some of the world’s most prominent scientists highlighting the crucial need for action, carbon emissions, biodiversity loss and sea level rises are still going up across the globe. So, what are we getting wrong? In this episode, we speak to leading researcher and author Mike Berners-Lee about his latest book A Climate of Truth, Why We Need it and How to Get It. He argues that truth and honesty are key if we are to avert what he refers to as the climate polycrisis. Facts and data need to be reported frankly and clearly, policymakers and business leaders need to be held to higher standards of honesty and when it comes down to it, we can all make a difference by educating ourselves, questioning the information we’re presented with and, ultimately, voting with our wallets.

These days we’re bombarded with information and claims that purport to explain almost every conceivable aspect of our lives, be it down to the bold assertions made by policymakers, the confidence of anonymity afforded by social media or just our natural human inclination to be fooled by a well-spoken know-it-all. But exactly who are the people making these claims, how do they reach their conclusions, and really, can anyone ever actually be certain about anything? In this episode, we catch up with the statistician, epidemiologist and author Adam Kucharski to take about his latest book Proof, The Uncertain Science of Uncertainty. He tells us how Abraham Lincoln’s background as lawyer led him to study the nature of proof beyond reasonable doubt and how it helped him to win his presidency, how picking holes in previous logical thinking enabled Albert Einstein to discover some of his greatest theories, and what the COVID pandemic taught us all about the value of scientific rigour and evidence-based conclusions.

The human brain is surely one of the most complex and fascinating creations in all of nature. It’s through them that we experience the world around us, develop knowledge and skills, and carry within us memories of events and experiences that occurred decades in the past, which we can later draw on to face new challenges. But when it comes to understanding exactly what is going on between our ears, we’re only just starting to scratch the surface. Could artificial intelligence technology help us in this quest? In this episode, we’re joined by Prof Andrew Saxe, a computational neuroscientist based at University College London. He tells us about the work his lab is carrying out on modelling the function of our brains using artificial intelligence, what this research has already uncovered about how our brains learn and what we can look forward to discovering in the coming decade or so.

She tells us how we are wired to comply, even if doing so comprises our true values, the far-reaching effect this has on our lives and the structure of society, and how by following her advice we can all unlock the power of a ‘True No’.
