Science Friction

A rock celebrity with a wild biography.  Saharan nomads, a weight-loss doctor feeding an unusual addiction, scientists seeking the origins of Everything. 'Black Beauty' has it all. The meteorite with a mighty story, with love from Mars.

Scientists Jonathan Napier and Cathie Martin remember when they needed armed guards and high fences to protect their genetic experiments. But the rules around genetically modified crops are rapidly changing. What could this mean for your dinner plate? (REPEAT)

A pair of twin girls is born in the late 1980s and their mother, Chris, is told a series of ‘facts’ about them.Each born with their own placenta, Chris is told it’s extremely unlikely that her twins are identical, but, if they were, they’d be a perfect DNA match. She’s also told that her daughters have a much higher likelihood as adults of conceiving twins themselves.These were the foundations of how Chris and her daughters understood their ‘twin-ness’ as they grew. But in recent years, new research has proven that none of these assertions is true.So what has science learned about twins in recent years and what are the mysteries that researchers are still trying to solve? And even if you’re not a twin, maybe you were at some point in your development? There could be a way to find out very soon.For RN Summer we're playing some our favourite programs from the past year.

Science journalist, biologist, podcaster, teacher and activist Dr Ilya Kolmanovsky is a superstar science communicator.He hosts one of the biggest Russian language podcasts. Bigger than podcasts on sex or politics.But he's no stranger to the brutality of Russia's political leadership.Now, with Putin's violent invasion of Ukraine and as a new Iron Curtain descends, Ilya and thousands of others inside Russia have just made the most wrenching decision of their lives.For RN Summer we're playing some our favourite programs from the past year.

Leading computer scientist and co-founder of Black in A.I, Dr Timnit Gebru, was hired by Google to co-lead its Ethical AI team with another tech industry trailblazer Dr Margaret Mitchell.The team investigated the ethics of artificial intelligence to understand and prevent its potential harms.Timnit was the first Black woman the company had employed in a research scientist role.Then Google terminated her contract sparking an international outcry.Some 7000 industry colleagues and others, including thousands within Google itself, signed a petition protesting her departure.Then Dr Margaret Mitchell was fired too.Now Timnit is driving "community-rooted" artificial intelligence research free from what she describes as "Big Tech's pervasive influence".For RN Summer we're playing some our favourite programs from the past year.

What does it take to reimagine your life?In this occasional Science Friction series, scientists who end-up their lives and strip themselves of their professional identity to become artists.Kolkata-born engineer Nishant Jain flew in the face of expectations, threw in a PhD in biomechanics, and reinvented himself as a cartoonist, writer, and self-taught artist.Now the self-described 'Sneaky Artist' hosts a podcast of the same name and sells his urban artworks to a growing global fanbase.For RN Summer we're playing some our favourite programs from the past year.

Two teams. Scientists and science journalists. Brains vs brains. Boys vs Girls. From the small (bed bug sex) to the big (er, the whole cosmos), it's the year in science with a tongue firmly in our cheeks.

The long prison sentence given to Sydney climate protester Deanna 'Violet' Coco for blocking traffic on the Sydney Harbour bridge has surprised many, including her fellow protester Jay, who spent 42 days under house arrest. Are new laws suppressing fundamental human rights to protest, or a proportionate response to disruptive blockades?Note: Since making the show, Violet Coco, has been released on bail, as from 13th December.

We make machines, but do our machines make us? And who's in control really? Superstar anthropologist, technologist, futurist, cyberneticist, and Silicon Valley insider Genevieve Bell and guests talk machines, minds and messing with the code to make the world so much better.
