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. Andrew is a finalist for the Blavatnik Awards for Young Scientists. https://blavatnikawards.org/news/items/finalists-announced-2025-uk-blavatnik-awards-young-scientists/ Learn more about your ad choices.

From the dramatic caves that bring to mind the pirates and smugglers of yore to the rolling sand dunes many of us likely played in as children, our coastlines are home to all manner of fascinating features, forged over centuries by crashing waves and harsh, unforgiving weather. But far from simply being picturesque, these landmarks can teach us about our planet’s past and ultimately, its future. In this episode, we speak to writer and author Matthew Yeomans about his latest book Seascape: Notes from a Changing Coastline. He speaks to us about the observations he made of the many and varied effects of climate change while walking along the Welsh coastline, how the threat of coastal flooding is very real and how nature-based solutions may well be the most effective way of protecting our precious coastlines.

Whether it’s from our friends, workmates or via various media platforms, both social and traditional, these days we’re all faced with a never-ending bombardment of information expressed through numbers, percentages and statistics. But how exactly should we go about interpreting them? In this episode we catch up with Prof Sir David Spiegelhalter, a statistician and science communicator based at the University of Cambridge. He shares some simple advice to help us understand how the risks and benefits of various lifestyle factors such as exercise and diet are presented to us, explains how framing can be used to make any number look big or small, and tells us what everyone, including scientists, could be doing better when we speak about numbers.

Whether it’s accepting a work assignment we know we don’t have time for, attending a social occasion even though we’d much rather hunker down at home with a cup of tea, or something more serious such as not speaking up when we witness an act of discrimination, many of us find it difficult to say ‘no’. But why is this? In this episode, we speak to psychologist Dr Sunita Sah about her latest book Defy, The Power of No in a World that Demands Yes. 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’.

Over the last century or so neuroscientists around the world have been uncovering more and more about how our very identities are formed by the different cognitive functions carried out by our brains. And we now know that our identities can even be transformed by brain disorders such as stroke, dementia of head injuries. In this episode, we catch up with neurologist Masud Husain to talk about his latest book – Our Brains, Our Selves, What a Neurologist’s Patients Taught Him about the Brain. He takes us through some of the discoveries he has made while treating patients during his long career. We learn how a stroke led to a previously successful, motivated man to suddenly lose interest in all areas of this life, how a previously demure, shy woman began dressing flamboyantly and insulting people in the street thanks to the effects of dementia and a woman suffering from Alzheimer’s began to think that there were multiple copies of her husband.

Be it a Marvel superhero, a fashion model or a professional athlete, we likely all have an image in our minds of what we wish our bodies looked like. But for some, the pressure of meeting these expectations can lead to the use of anabolic steroids in an attempt to get that Hollywood or magazine cover look. In this episode, we speak to Dr Orlanda Harvey, a senior lecturer in social work based at Bournemouth University. She tells us what steroids do to our bodies, the various motivations recreational users have for using them and the health issues, both for body and mind, that can arise from doing so.

Whether it’s due to deadlines at work, an upcoming exam or a rocky personal relationship, we’ve no doubt all felt stress at some point in our lives. And while a certain amount of stress can help to motivate us and make us more productive, if things get too much, stress can have a significant effect on both our mental and physical health. In this episode, we speak to Despina Djama, a psychologist and stress researcher based at the University of Plymouth. She tells us what happens in our brains and bodies when we experience stress, explains how the reaction stems from our evolutionary fight or flight response and shares some tips and techniques we can all use to help us get through stressful times.

Many of us listen to music every day, perhaps to help us relax in the evening after a hard day’s work, get us through a tough workout or maybe even to allow us to feel closer to absent loved ones. There can be no doubt that music plays a huge part in what it means to be human. In this episode, we catch up with neuroscientist and musician Daniel Levitin to talk about his latest book Music as Medicine: How We Can Harness Its Therapeutic Power. He tells us what happens in our bodies and brains when we listen to music or play an instrument, explains the unique relationship between music and memory, and details how music can be used as a powerful therapeutic tool to help patients struggling from everything from Alzheimer’s disease to post traumatic stress disorder.

Most of us like to think we live in an equal society that offers the same opportunities to all. But unfortunately, hundreds of scientific studies say otherwise. Racial bias is essentially everywhere, often hiding in plain sight. For example, did you know that black people are as much as 50 per cent less likely to be called in for a job interview than a similarly qualified white person? Or that children of colour are more likely to be viewed as troublemakers at school? In this episode, we speak to Prof Keon West about his latest book The Science of Racism – Everything You Need to Know but Probably Don’t – Yet. He tells us how racism is so deeply baked into many of our societal systems, explains the issues surrounding the concept of ‘colour blindness’ and how we can all benefit from simply interacting with more people from different ethnicities and backgrounds.

It’s commonly thought that when compared to other members of the animal kingdom we humans have a particularly poor sense of smell. But this couldn’t be further from the truth. Modern research has proven that human beings are surprisingly sophisticated sniffers, at least on par with the vast majority of other animals. In this episode, we catch up with Prof Jonas Olofsson, a psychologist based at Stockholm University, to talk about his latest book The Forgotten Sense – The New Science of Smell. He explains what happens when odour molecules enter our nasal passages and are processed by our brains, tells us how our sense of smell is intimately linked to our memories and emotions and answers the question that has been debated across countless dinner tables all over the world: can some people really identify wines just by smelling them?

This time of the year lots of us will be setting new goals for the future. Be it getting fitter, reading more or even writing that novel we always suspected we had in us. But why do so many of us fail to see these plans through? In this episode, we catch up Dr Ian Taylor a reader in motivational science based at Loughborough University. He tells us why we are prone to setting goals that are too ambitious and why starting small is usually the best approach, why we shouldn’t worry if our routine drops off now and again, and why simply having willpower isn’t the be all and end all of reaching your targets, whatever they are.

This podcast's guest, who I think is @kwdetal, said that dogs can't feel guilt. Please search YouTube for "Denver the guilty dog" because that video clearly proves that statement is not true!

I found Gretchen McCulloch to be intensely annoying for two main reasons: 1. She speaks at the speed of a machine gun 2. Whilst I appreciate passion, "over passionate" would be level 11, and she's a solid 20.

great podcast, but if one 100 light bulb is twice as far away as another, then the closer one will appear to be four times brighter not twice as bright (38 mins)
