How can we, humans, look at our relationship to nature differently? In season three of Going Wild, on top of stories about animals, we invite you to journey through the entire ecological web — from the tiniest of life forms to apex predators — alongside the scientists, activists and adventurers who study it. Wildlife biologist and host Dr. Rae Wynn-Grant has been studying wild animals in their natural habitats all over the world for years. Our award-winning podcast takes you inside the hidde ...

Flash Forward is a show about possible (and not so possible) future scenarios. What would the warranty on a sex robot look like? How would diplomacy work if we couldn’t lie? Could there ever be a fecal transplant black market? (Complicated, it wouldn’t, and yes, respectively, in case you’re curious.) Hosted and produced by award winning science journalist Rose Eveleth, each episode combines audio drama and journalism to go deep on potential tomorrows, and uncovers what those futures might re ...

DNA science. Artificial intelligence. Smartphones and 3D printers. Science and technology have transformed the world we live in. But how did we get here? It wasn’t by accident. Well, sometimes it was. It was also the result of hard work, teamwork, and competition. And incredibly surprising moments.

Sara Walker: How the Origin of Life Could Guide Our Search for Aliens [Ep. 456]

What is the connection between the origin of life on Earth and the search for extraterrestrial life? Could a revolutionary new theory guide us in our search for aliens? And is consciousness an inevitable outcome of life’s complexity, or is it something more mysterious?
I had the pleasure of discussing these fascinating issues with the incredible astrobiologist and theoretical physicist Sara Walker. Sara has greatly contributed to our understanding of how life emerges from non-living matter and how information processing in biological systems differs from that in non-living systems. Her work often explores the intersections of physics, biology, and information theory, seeking to uncover the fundamental principles that govern the transition from chemistry to biology.
In this episode, we dive deep into the mysteries of life, assembly theory, consciousness, and life beyond Earth.
