• 4. Consciousness: From Zombies to Beast Machines

  Why is there something it’s like to be you – and could AI ever be truly conscious? In Episode 4 of Leafing Through Science, neuroscientist and bestselling author Anil Seth joins Hedi to explore the mystery at the heart of his acclaimed book Being You: A New Science of Consciousness.From philosophical zombies and the purpose of dreaming, to measuring consciousness like temperature and why brains aren’t computers, Seth unpacks the idea that our experience of reality – and of ourselves – is a kind of waking dream, a “controlled hallucination”, shaped by prediction, perception, and the body’s primal drive to stay alive. His theory of what it means to ‘be you’ challenges how we understand perception – and turns what you thought you knew about yourself on its head.Every two weeks, the new podcast series Leafing Through Science brings together host Hedi Young, Champalimaud Foundation neuroscientist and science communicator, with the authors behind some of the most fascinating non-fiction books in the life sciences. From new releases to timeless classics, we explore everything from consciousness and free will, to alien hands and minds under siege.

• 3. Inside OCD: White Bears and Blizzards

  In Episode 3 of Leafing Through Science, Hedi sits down with David Adam – science writer and author of the bestseller The Man Who Couldn't Stop: The Truth About OCD – to explore the strange and unrelenting world of obsessive compulsive disorder (OCD).What drives someone to fear their own thoughts, or an Ethiopian schoolgirl to eat the wall of her house, bit by bit? Why do millions of us get stuck in loops of doubt and dread? And what does it mean to have a brain that simply won’t let go?David reveals the hidden mechanics of OCD – from the weird thoughts that exist within us all, to the condition’s so-called “patient zero”, white bears and Winston Churchill’s own battle with egodystonia. David traces the fine line between ordinary mental noise and debilitating compulsion and gives an honest account of his own struggles.Along the way, their discussion challenges the notion of what counts as “normal” thought, and reflects on the evolution of treatment – from lobotomies and cavalier surgeons to today’s more effective, evidence-based approaches like Cognitive Behavioural Therapy.Every two weeks, the podcast series Leafing Through Science brings together host Hedi Young, Champalimaud Foundation neuroscientist and science communicator, with the authors behind some of the most fascinating non-fiction books in the life sciences. We explore everything from the mysteries of consciousness and free will, to alien hands and minds under siege.

• 2. Beyond the Beat: The Heart You Didn’t Know You Had

  Sian Harding, a world leader in cardiac research, joins Hedi to reveal the heart as you’ve never seen it before, as they discuss her book The Exquisite Machine: The New Science of the Heart. From how social rank, air pollution, noise, and even your mother’s pregnancy diet can shape heart health, to the heart’s mini-brain or growing hearts in the lab from skin cells, they uncover the remarkable ways this muscular organ does far more than “just” pump blood.They also talk about how the heart doesn’t only respond to emotions – it creates them too – and how a broken heart is more than just a metaphor, as we explore the mystery behind “Broken Heart Syndrome” and the heart’s response to emotional shock. Harding takes us on an eye-opening journey through the science that’s rewriting how we understand our body’s most poetic organ – and how it could help us tackle one of the world’s biggest health challenges.Relevant links:“The Exquisite Machine: The New Science of the Heart” by Sian E.

• 1. How the Brain Creates the Body: Who Moved My Hand? (Part 2)

  Following Episode 1 - Part 1, this second part of Hedi’s conversation with science writer Moheb Costandi unpacks how our sense of agency – the feeling of being in control of our actions and responsible for their outcomes – can be disrupted in conditions like Alien Hand Syndrome and schizophrenia, manipulated on the operating table, or even altered in everyday life. Their discussion also ranges from the science behind anorexia nervosa and Alice in Wonderland Syndrome to peripersonal space – the invisible bubble around our bodies that helps define the boundary between self and world.
