Dr. Joanna Moncrieff is a psychiatrist, researcher, and author of The Myth of the Chemical Cure and Chemically Imbalanced, whose work has radically challenged one of the most powerful ideas in modern psychiatry — that depression is caused by a serotonin imbalance. Her landmark 2022 review in Molecular Psychiatry dismantled the serotonin hypothesis, exposing how Big Pharma turned a shaky theory into a multi‑billion‑dollar industry.

Read the review: https://www.nature.com/articles/s41380-022-01661-0

Expect to learn why the serotonin “chemical imbalance” story became the biggest myth in mental health, how SSRIs actually work — and why their benefits may be no greater than placebo, the shocking prevalence of emotional blunting and sexual dysfunction, why nearly 1 in 4 women in the UK are now on antidepressants, how Big Pharma engineered one of the most influential disinformation campaigns in medicine, what depression really is if not a brain disorder, why environmental factors far outweigh genes, the overlooked power of placebo, and why Joanna believes SSRIs may be doing more harm than good.

Johnjoe McFadden is a molecular geneticist, consciousness theorist, and best-selling co-author of Life on the Edge — the book that brought quantum mechanics into biology and shattered how we think about life itself.

He pioneered the first fully electronic rapid diagnostic test for deadly diseases like meningitis and COVID, and his groundbreaking work helped create the field of quantum biology — showing how enzymes, photosynthesis, even bird migration rely on quantum weirdness to function.

His bold CEMI Field Theory claims that your consciousness isn’t locked in your neuron's at all — it’s broadcast through your brain’s electromagnetic field. If true, it could finally solve the binding problem and change everything we know about the mind.

Expect to learn why life depends on quantum particles dancing through your cells, how robins literally see the Earth’s magnetic field, why DNA mutations may be driven by quantum tunnelling, why quantum biology might hold the key to free will, and how the brain’s invisible field could be the seat of your conscious experience — plus what that means for AI, evolution, and the very nature of reality...

Dr. Evelina Fedorenko is a cognitive neuroscientist at MIT and one of the world’s leading experts on how the brain processes language.

She’s mapped the brain’s language system more precisely than anyone, proving it’s a specialized network — not shared with general thought — and that our inner monologue? It might be an illusion. Now, her lab is using large language models like GPT to predict and even control neural activity in human language regions, revealing uncanny parallels between artificial and biological intelligence.

Expect to learn why you don’t actually think in words, how language and thought are distinct systems in the brain, why GPT-style models light up the same brain regions as human speech, what “drive” and “suppress” sentences reveal about how we process meaning, how hyperpolyglots learn 20+ languages using the same neural real estate, how bilingualism changes your brain, what language does that other mammals never evolved, how AI could reshape neuroscience research, whether machines could ever be conscious — and much more…

Nick Lane is a biochemist, Professor of Evolutionary Biochemistry at University College London, and author of Transformer, The Vital Question, and Power, Sex, Suicide — books that have revolutionised how we think about the origin of life, complexity, and the deep chemistry powering consciousness.

Life, Lane argues, didn’t begin in a soup but in the cracks of the seafloor — powered not by sunlight, but by geochemical gradients, ancient electricity, and the quiet inevitability of metabolism. And astonishingly, those same forces still flow through your cells — and possibly your mind.

Expect to learn how life may have started in alkaline hydrothermal vents, why proton gradients might be more fundamental than DNA, how ATP synthase works like a microscopic motor powered by a field strength equal to a bolt of lightning, why mitochondria changed everything for complex life, how consciousness could emerge from electrical charge flow, whether bacterial cells might have feelings, why Lane rejects panpsychism but entertains “cellular sentience,” how the structure of life reflects planetary energy flow, and what this all means for AI, aging, and the nature of being alive.

Dr. Michael Levin is a biologist, computer scientist, and co-creator of the Xenobot — the world’s first living, programmable organism, built entirely from frog skin and heart cells. These tiny constructs can move, heal, and even replicate — making them the first-ever synthetic life forms capable of self-replication.

But this is just the beginning.

Dr. Levin’s research into bioelectricity is flipping biology on its head. He’s shown that cells use electrical signals — not just genes — to communicate, store memories, and make decisions. He’s grown eyes on tadpole tails, regenerated limbs, and reprogrammed cancer — all by changing cellular voltage, not DNA.Expect to learn why intelligence might exist in every tissue of your body, how cells solve problems without brains, why memory can persist even after decapitation, how Xenobots replicate without a genetic blueprint, why bioelectricity may be the true architecture of consciousness, how Levin’s discoveries could transform medicine, ethics, and AI — and why your liver might be more self-aware than you think.

James Glattfelder is a physicist and complexity theorist turned philosopher of mind and reality, and author of The Sapient Cosmos — a provocative attempt to rethink the universe as fundamentally conscious and informational.

Forget what you think you know about space, time, matter, or even consciousness. Glattfelder believes that reality isn’t built from particles, but from information — and that consciousness might not emerge from brains, but be the very substrate of the cosmos itself.

Expect to learn what information really is and why it might be more fundamental than matter, how quantum field theory dismantles our intuitions about physical reality, why space and time might be illusions, how Integrated Information Theory bridges consciousness and physics, whether psychedelics are revealing a deeper layer of reality or just distorting it, how idealism offers an alternative to materialism, what syncretic idealism actually means, and why the hard problem of consciousness might only be hard because we’re asking the wrong questions.

This is an episode for anyone who’s ever wondered whether the universe might be thinking — and whether we’re just the thoughts.

Dr. Mark Williams is a cognitive neuroscientist, author of The Connected Species, and one of the world’s leading experts on how we learn, connect, and perceive reality — and why modern life may be rewiring our brains in ways we don’t fully understand.

Your brain is not showing you the world as it is — it’s hallucinating a version that helps you survive. And that illusion is breaking down. Especially for children.

Expect to learn why reality itself is a convincing hallucination created by your brain, how technology is disrupting emotional development and attention in kids, why screen time is linked to lower empathy and memory, how facial expressions are learned (and what happens when they aren’t), why multitasking ruins learning, how AI could both help and harm education, why sleep is critical for memory, why writing is better than typing, and how to reimagine schools based on what the brain actually needs.

Plus — the incredible story of how Dr. Williams went from high-school dropout to MIT neuroscientist, and what it taught him about human potential.

Peter Godfrey-Smith is a philosopher of biology, diver, and author of Other Minds and Metazoa — two of the most important works on animal consciousness ever written.

His research explores the octopus not just as an animal, but as an alien intelligence that evolved a complex mind entirely separate from our own.

Octopuses have distributed brains in their arms, no cultural learning, no social lives — and yet they solve problems, play, and even throw objects in rage. They live just 1 to 2 years, mate once, and die — raising a profound question: why would evolution build a mind this sophisticated, only to delete it almost immediately?

Expect to learn why octopus intelligence forces us to rethink consciousness, how their nervous system creates agency without central control, what their bizarre lifespan reveals about the trade-offs of intelligence, why cultural learning might not be necessary for sentience, whether octopuses might dream, and what this means for how subjective experience evolved on Earth. You'll also learn how consciousness may have emerged from sensory integration, how language reshaped the human mind, why inner speech might be the key to unified awareness, whether arms can think, if AI can ever feel — and why octopuses might be the only creatures smart enough to understand what they are, but not live long enough to tell us.
