  • Why our brains struggle to keep up with a rapidly changing world

    Why our brains struggle to keep up with a rapidly changing world
    Mar 20 2026
    The human brain is undoubtedly one of the true marvels of nature. But many of the neural mechanisms that evolved to keep our ancestors alive over thousands of years are now leaving us feeling dissatisfied, anxious and depressed thanks to the rapid advances in technology and culture we now find ourselves faced with. The simple fact is, we’re living in an environment that our brains were not built to survive in. In this episode, we’re joined by Dr Paul Goldsmith, an evolutionary neuroscientist, author and visiting professor at Imperial College London, to talk about his latest book, The Evolving Brain – An Ancient Tool in a Modern World. He tells us how the pressures and goals many of us are now confronted with are vastly different from the challenges faced by our ancestors, the huge impact this is having on our mental wellbeing by excessively triggering our natural stress responses and shares some advice from neuroscience we can all use to navigate the trials of modern life more healthily.

  • Why we need to save ugly, creepy, scary and misunderstood animals

    Why we need to save ugly, creepy, scary and misunderstood animals
    Mar 16 2026
    The natural world is filled with a rich tapestry of creatures, each occupying a unique evolutionary niche that helps to keep the ecosystems they live in functioning healthily. But the truth is, over the centuries, we humans have treated some of them better than others. Our tendency is to prefer cute, cuddly animals such as pandas or donkeys, or beautiful, majestic beasts such as elephants, eagles or tigers. Is it time that we had a long, hard look at this viewpoint, and extended our care and attention to the animals that we’ve traditionally viewed as ugly, creepy or even dangerous? In this episode, we’re joined by Jo Wimpenny an author and specialist in animal behaviour, to talk about her latest book, Beauty of the Beasts – Rethinking Nature’s Least Loved Animals. She tells us how the latest research is showing that snake venom can potentially give rise to a new category of medicinal drugs, how the insects we typically find disgusting such as maggots and cockroaches play a vital role as the natural caretakers of the environments they live in, and how, by rethinking our in-built prejudices, we can more deeply appreciate the richness and variety found in the natural world.

  • How to spot the telltale signs of lying using linguistics

    How to spot the telltale signs of lying using linguistics
    Mar 9 2026
    How can we tell if someone we’re speaking to is being economical with the truth? Oftentimes, we’re told that the primary telltale signs lie in the use of body language – maybe someone is avoiding eye contact, touching their face a lot, or fidgeting and squirming. But there’s also a whole world of clues to look out for in the type of language that someone uses when they’re telling us lies. In this episode, we’re joined by Dr Kirsty King, a lecturer in communication based at University College London, to talk about her latest book, The Language of Lies – How to Uncover the Liar in Your Life. She tells us that when people try to hide the truth, they tend to use language that distances themselves from the act they’re talking about or the people involved in it, how when we’re relating a false account of an event we tend to omit words that describe how we actually felt during it, and how even the way liars structure their sentences can be a signal that they are trying to deceive us.

  • Why understanding what makes us hungry is key to weight loss

    Why understanding what makes us hungry is key to weight loss
    Mar 6 2026
    Chances are that if any of us are looking to drop a bit of excess weight, the first thing we’ll attempt is to cut down the number of calories we’re consuming. For decades, we’ve been told that balancing the number of calories we put into to our bodies with the energy that we burn can help us to maintain a healthy weight. While this is true, could it be that we’re putting our attention and effort in the wrong place and that taking a bigger picture view of the factors that motivate our appetite is likely to be a much more successful strategy? In this episode, we’re joined by Dr Jason Fung, a physician and best-selling author based in Toronto, to talk about his latest book, The Hunger Code – Resetting Your Body’s Fat Thermostat in the Age of Ultra-processed Food. He talks us through the three key drivers that control our feelings of hunger, how our hormones are deeply connected with our appetites, and how the environments we live in have a profound effect on the food we eat.

  • How to slash your dementia risk in 12 weeks

    How to slash your dementia risk in 12 weeks
    Mar 2 2026
    Around the world, more than 50 million people are living with some form of dementia – a number expected to triple by 2050 as populations age. But the thing is, dementia is often talked about as a kind of genetic lottery. You either get lucky and escape it, or unlucky and develop it. But what if that framing is wrong? What if far more of our brain health is within our control than we’ve been led to believe? Our guest today is Dr Majid Fotuhi, a neuroscientist who has spent decades treating and studying people with cognitive impairment. His message is a bold one: dementia is largely preventable – not with a miracle pill or silver-bullet treatment, but through the way we live. The 12-week programme he and his team have developed has helped his patients improve their memory, regain independence, and even grow new brain connections. Today, he talks us through the essentials of the programme – and what it really takes to stay sharp for life. Learn more about your ad choices. Visit podcastchoices.com/adchoices

  • Why connecting with others is vital for our mental health

    Why connecting with others is vital for our mental health
    Feb 27 2026
    Statistics show that half of us will experience a mental health condition of some kind by the time we turn forty. Could this be due to the increasing pressures and looming crises we’re currently facing in the modern world, overstimulating natural responses in our brains and bodies that have evolved over hundreds of thousands of years to protect us from threats? In this episode, we’re joined by Dr Joanna Cheek, a psychiatrist, psychotherapist and clinical professor based at the University of British Columbia’s Faculty of Medicine, to talk about her latest book, It’s Not You, It’s the World – A Mental Health Survival Guide for Us All. She tells us how the system of alarm signals in our brains is being increasingly triggered by the rapidly changing circumstances we find ourselves in, how this is hijacking the push and pull of our natural risk/reward systems, and why connecting more deeply with the rich tapestry of the people and cultures we share the world with can help us all bring our lives back into balance.

  • How metabolism really affects your health, weight and wellbeing

    How metabolism really affects your health, weight and wellbeing
    Feb 23 2026
    Whether we’re working at a desk in an office, running a marathon or even asleep in bed, our bodies are host to thousands of chemical processes that are continually converting the food we eat into energy and repairing our bones, muscles and organs. Collectively these processes are known as the metabolism. But how are they affected by our genes, lifestyles and diet, and what can we do to make sure everything stays running smoothly? In this episode, we’re joined by Javier Gonzalez, a professor of nutrition and metabolism based at the University of Bath. He breaks down the links between our metabolisms and body types, tells us why our metabolisms aren’t necessarily fixed for life, and explains why it’s almost impossible to out exercise a poor diet if you’re looking to drop a few kilos.
