Science Friction's latest season is: Artificial Evolution. In 1996, Dolly the Sheep became the first ever cloned animal. Nearly 30 years later, genetic technology has reshaped the world around us. What exactly has happened, where are we headed, and are we OK about it?
In this series, environment reporter Peter de Kruijff tells the surprising stories of genetic engineering. Meet the scientists changing the food we eat and creating animals with organs we can use. Hear about the criminal conspiracy to clone a giant sheep, and the teams bringing extinct animals back from the dead.
Artificial Evolution traces the influence of genetic technology from Dolly into the future. It’s the latest series of Science Friction, an award-winning podcast from ABC Radio National.
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.

Over the past few years, you might have heard advertisements in your podcast feed or on social media for electrolyte supplements.
If you haven’t seen them, they’re basically these little sachets or tubs that get mixed in with water as a drink.
News media reports demand for such products is exploding – with the market for electrolyte supplements set to grow to 112 billion dollars by 2030, more than doubling in size in less than a decade.
They go by a bunch of different names … and their marketing often suggests we could all use more electrolytes in our life.
But what’s the science on this swing towards salty beverages? Who actually needs them? And what does our obsession with optimised hydration … say about us?
