Why OCD is a serious, debilitating mental condition, not just a need for cleanliness or order
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 clinical psychologist 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.

How truth and honesty are key to tackling the climate crisis
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.

How to combat uncertainty in a post-truth world
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.

How AI is helping us to understand how our brains learn
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.

What our coastlines can tell us about the planet’s past and future
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.

How to see through misleading numbers and statistics
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.

How psychology can help us unlock the power of saying ‘no’
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’.

How our brains create our sense of self
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.

How body image pressures lead to steroid use
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.

Healthy Start: How making small behavioural changes can help us cope better with stress
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.

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.
