We’re back and we’ve got some questions. Weight-loss injections are reshaping more than waistlines. They’re changing the world we live in. Drugs like Ozempic were developed to treat diabetes, but now they’re transforming how we eat, fly, dress and maybe how we think about our impulses. This week, Emma Kennedy is joined by Professor Giles Yeo, obesity researcher at Cambridge University and author of Why Calories Don’t Count: How we got the science of weight loss wrong, to help us wrap our heads around how these so-called “skinny jabs” are changing everything.

We’re back and we’ve got some questions. How does fake news pull us in? From deepfakes to dodgy headlines, we’re constantly navigating a minefield of misinformation. It spreads faster than the truth, plays on our emotions, and can confirm what we want to believe.  This week, Emma Kennedy is joined by Dr. Gordon Pennycook, Associate Professor of Psychology at Cornell University and Dr. David Rand, Professor of Brain and Cognitive Sciences at MIT, to find out why it is so hard to combat fake news?  WHY? is presented by Emma Kennedy.

We’re back and we’ve got some questions. What is laughter? A joyful cackle, a nervous snort, a full-body wheeze. It’s how we react when life gets silly, or sometimes painful, or uncomfortable. We laugh to connect, to disarm and, sometimes, to survive.  This week, Emma Kennedy is joined by Laura Lexx, professional comedian with an actual masters in stand up comedy and host of Lexx Education, to help us decode the giggle. Why do we laugh?  Is it really contagious?  WHY? is presented by Emma Kennedy. Produced by Liam Tait and Kathleen Johnson. Edited by Dominic Delargy. Theme music by Jade Bailey.

We’re back and we’ve got some questions. Sex, attraction, identity all bring up strong debates. For years, scientists have tried to pin down why we fancy who we fancy. Genes? Brain chemistry? Vibes? There’s no tidy answer – but could we be on the cusp of a scientific explanation? This week, Emma Kennedy is joined by geneticist and neuroscientist Dr Kevin Mitchell, associate professor at Trinity College Dublin to talk about attraction, the ‘gay gene’, and the universal appeal of prime David Beckham.

We’re back and we’ve got some questions. When Jurassic Park roared into cinemas in 1993, it wasn’t just the dinosaurs that captured our imaginations – it was the idea that science might one day bring the prehistoric creatures back to life. Three decades and seven blockbusters later, the science of resurrection is edging closer to reality. Could we really bring back the dinosaurs? This week, Emma Kennedy talks to Professor Andrew Pask, a geneticist at the University of Melbourne, about his mission to revive the Tasmanian tiger – and why recreating truly prehistoric species remains a scientific riddle.

We’re back and we’ve got some questions. Why are we so obsessed with being special?Today, we’re diving into the strange modern urge to define ourselves at all costs. Online, in politics and beyond identity has become our currency. But as the world tilts into climate collapse, A.I. dread, and whatever mess Donald Trump’s cooking up, maybe it’s time to ask: who are we without all the labels? Emma Kennedy is joined by Alexander Douglas, philosopher and author of Against Identity, to explore why clinging to identity might be doing more harm than good.

We’re back and we’ve got some questions. Billionaires want to live forever – and they might just pull it off. From young blood transfusions to gene-hacking and basement labs chasing eternal youth, the ultra-rich are pouring fortunes into cheating death. But if Bezos, Thiel and co get to slow ageing, what happens to the rest of us?  Emma Kennedy talks to Richard Faragher, Professor of Biological Gerontology at the University of Brighton, and Dr. Paul Root Wolpe, Director of the Center for Ethics at Emory University, to find out what could happen if billionaires unlock immortality.

We’re back and we’ve got questions. From misdiagnosed heart attacks to the gaslighting of chronic pain, women’s health has been stuck in triage for far too long. Women are told to trust the system – but what if the system was never built for them in the first place?

We’re back and we’ve got questions. We always imagine first contact with aliens as a conversation. But what if talking is the problem? How could we ever prepare for the awkward opening lines of interstellar diplomacy? Well, here on Earth, we might already have a clue: the octopus. They learn, play, and can even recognise human faces. So could our eight-tentacled friends help us understand intelligence beyond our own planet?

We’re back and we’ve got some questions. The rules around sex are changing: what was once considered taboo is becoming the norm – and even The Guardian is dishing out kinky tips to their readers.

Phobias are the most common anxiety disorder in the world. We’re very familiar with the likes of arachnophobia and claustrophobia, but some people suffer from more unconventional, even bizarre fears – say, a terror of buttons or even spoons.

LeDoux, Professor of Neuroscience at NYU, and clinical psychologist Dr Ali Mattu who has treated anxiety disorders in New York’s top hospitals.  • Buy Joseph E.

The concept of eternal life is a long-standing fantasy in science fiction, but will it ever be possible to upload our consciousness to an external host –  or even a robot? Will there be a day when we can upload the very essence of our being, the things that make us human, into some kind of machine? And if we could, what would it do to our humanity?  To find out, Emma Kennedy is joined by Anil Seth, Professor of Cognitive and Computational Neuroscience at the University of Sussex and Douglas Rushkoff, Professor of Media Theory and Digital Economics at the City University of New York, Queens College.   Buy Anil Seth’s Being You: A New Science of Consciousness and Douglas Rushkoff’s Survival of the Richest: Escape Fantasies of the Tech Billionaires through our affiliate bookshop and you’ll help fund WHY? by earning us a small commission for every sale.

Space is fundamentally quite weird, and seldom as weird as the thousands of “exoplanets” that – we’ve fairly recently discovered – exist outside of our solar system. We’re all familiar with the likes of Tatooine from Star Wars and Krypton from Superman, but what are the REAL exoplanets like? And how do filmmakers turn these planets from figments of imagination into something immersive that look and feel real to audiences?    To find out, Emma Kennedy talks to Lisa Kaltenegger, world-leading astronomer and author of Alien Earths: The Search for Life in the Cosmos and Paul Franklin, Oscar-winning Visual FX Supervisor and co-founder of the digital effects company DNEG.     Buy Lisa Kaltenegger’s Alien Earths: The Search for Life in the Cosmos through our affiliate bookshop and you’ll help fund WHY? by earning us a small commission for every sale.

Since the first contraceptive pill came out in 1961, the burden of birth control has fallen overwhelmingly on women. While women have numerous birth control options – each with its own long list of dizzying side effects – men only have two, and there hasn’t been a new commercial contraceptive for men in decades. So, why isn’t there a male pill yet? And would men even take it if there was?     Emma Kennedy talks to two experts on contraception – endocrinology professor Stephanie Page and associate sociology professor Krystale Littlejohn, author of Just Get on the Pill: The Uneven Burden of Reproductive Politics – to find out why the uneven burden of contraception isn’t just a medical issue, but a sociological one.     • Buy Krystale’s book Just Get on the Pill: The Uneven Burden of Reproductive Politics through our affiliate bookshop and you’ll help fund WHY? by earning us a small commission from every sale.

If you can think of it, someone probably has a fetish for it. Whether you’re into feet, balloons, chair legs or latex, one thing’s for sure – fetishes are still a taboo subject, and not something we often discuss with others. But how do fetishes develop, and how can people partake in fetishes in a safe and ethical way?     Emma Kennedy delves into the science and sociology of fetishes with Justin Lehmiller, Research Fellow in Sex, Gender and Reproduction at the Kinsey Institute, and award-winning clinical sexologist and sexuality educator Sunny Megatron.   Buy Justin’s book Tell Me What You Want: The Science of Sexual Desire and How it Can Help You Improve Your Sex Life through our affiliate bookshop and you’ll help fund WHY?

Time travel was once the holy grail of science fiction, but scientists have now shown that time travel into the future is theoretically possible – so why not backwards? If we can use the quirks of physics to move into the future “faster” than we’d get there anyway, could it be possible to move into the past? And if time travel in either direction became possible, what would it do to our world… and ourselves?    Emma Kennedy asks Jim Al-Khalili, famed for The Life Scientific and professor of theoretical physics at the University of Surrey, and Nikk Effingham, professor of philosophy at the University of Birmingham, about our days of future past.    Buy Nikk’s book Does Tomorrow Exist?: A Debate through our affiliate bookshop and you’ll help fund Why? by earning us a small commission for every sale.
