Why does medicine ignore women? with Naga Munchetty
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?
This week, Emma Kennedy talks to TV presenter and author of It’s Probably Nothing: Critical Conversations on the Women’s Health Crisis, Naga Munchetty, to ask: why does modern medicine keep failing women?

How could we talk to space aliens?
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?
Emma Kennedy talks to mollusc expert Dr. Tim Pearce, curator and the head of the Section of Mollusks at Carnegie Museum of Natural History, to find out how we might one day communicate with life from the stars.

Why do swingers swing?
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. Why are we now more honest about our sexual desires than ever before? Why are so many of us willing to engage in these non-traditional desires?
Emma Kennedy talks to psychosexual therapist Dr Kate Moyle, author of The Science of Sex: Every Question About Your Sex Life Answered, to find out just why swingers swing?

Why do we have phobias?
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. Where do they come from? What do they mean? And can they be treated? Emma Kennedy talks to Joseph E. 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.

Why are planets so weird?
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.

Why aren’t men on the Pill?
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.
