If we don’t build a more sustainable world our civilisation will collapse, potentially in the coming decades. Paul Behrens spends his time researching our impact on the world, and working out how civilisation can transition to a sustainable future. Covering multitudes of Lego to plant-based diets and solar power, we explore how we can create a civilisation to help humanity thrive in the future.

In our second quick-hit explainer episode this week, Tim breaks down how AI might be disrupting—not advancing—health science. Is the hype overshadowing real medical insight? Tune in for a sharp take on where AI could be leading us astray.

In this quick bonus episode, Tim breaks down one of science’s most intriguing mysteries as featured in BBC News today: the difference between matter and antimatter. Join us for a bite-sized explainer that sheds light on the surprising facts behind this cosmic puzzle!

Theoretical physics has two theories at its core that are not straightforward to link – quantum mechanics and general relativity. Lee Smolin, one of the world’s greatest living theoretical physicists, has spent his career working out why the theory of quantum mechanics is incomplete and how it might link to general relativity. He is an advocate of versions of quantum loop gravity. His work to marry the two theories resulted in him developing the theory of cosmological natural selection. Join Syma and Tim as they talk to Lee about theoretical physics.

His book is called Einstein's Unfinished Revolution: The Search for What Lies Beyond the Quantum and was published in 2019 by Penguin. https://www.penguin.co.uk/books/269402/einsteins-unfinished-revolution-by-smolin-lee/9780141979168

Biodiversity is under threat, and there are many ongoing efforts to help save it, including from within universities. But are academic contributions doing any good? Our cohost Tim Coulson discussed this topic with Professor Dame EJ Milner-Gulland in the Oxford Martin School (OMS) in April. Thanks to Carlyn Samuel, OMS and the OMS team for hosting the debate and allowing us to record.

Artificial intelligence is a modern-day technology that will impact the way we live much as past innovations like mastering fire, and inventing the printing press, home computers and the internet changed civilisation. But what exactly is it, how does it work, and what are the opportunities and risks of its continued development? We talk to Chris Summerfield about Artificial Intelligence and his fabulous new book, “These Strange New Minds: How AI Learned to Talk and What It Means” recently published by Penguin.

Colossal Bioscience has brought genetic variation back from the grave. It is a remarkable technological achievement, but is it species de-extinction? In this second part of this podcast we talk to Professor Peter Hudson FRS, a world-leading ecologist, who is concerned by Colossal’s claims and what they might mean.

Colossal Bioscience has brought genetic variation back from the grave. It is a remarkable technological achievement, but is it species de-extinction? We talk to Professor Bridgett vonHoldt, a world-leading dog geneticist, who was involved in Colossal Bioscience’s recent dire wolf de-extinction work that has caused some controversy. In part 2 of this podcast we talk a world-leading ecologist who gives us his - different - take.

The link below is a genetics paper, not talking about de-extinction.
