Science Friction

Science Friction's latest season is: The Challenger Legacy.  In January 1986, the Challenger space shuttle disintegrated 73 seconds after lift-off. This is the story of how the tragedy unfolded, the engineers who tried to stop it — and the enduring consequences for humanity's exploration of space.  Artificial Evolution (Season 4): Three decades ago, Dolly the Sheep became the first ever cloned mammal. Nearly 30 years later, genetic technology has reshaped the world around us. Environment reporter Peter de Kruijff explores what's changed, where we are headed, and whether we're okay with it. Brain Rot (Season 3): How does being chronically online affect our brains? Technology reporter Ange Lavoipierre explores the wildest ways people are using tech — from falling in love with AI companions to data-dumping a life into a language model — and the big questions about our own screen use. Cooked (Season 2): Why do some studies show ice cream is good for you? Why do some people say they feel good going carnivore, and do we really need as many electrolytes as the internet tells us? Food and nutrition scientist Dr Emma Beckett cuts through these confusing findings to explain how nutrition science works. AI Overlords (Season 1): AI didn't come from nowhere, and its development hasn't been a smooth, straight line — it's been rife with drama, conflict and disagreement. Technology reporter James Purtill looks at where AI came from, who controls it and where it's heading.
