Ep174 "Can Evolution Teach AI?" with Athena Aktipis
Ep174 "Can Evolution Teach AI?" with Athena Aktipis Oct 12, 2026 3180 How do you get trillions of cells to collaborate as the single organism that we call you? Does that kind of cooperation create opportunities for hijacking -- for example, is cancer a form of "cellular cheating"? Can we take the lessons learned from biology and apply them to understanding politics? And what do models of cooperation tell us about building and living with AI? Join Eagleman 
Re-Release  "Why Do Brains Dream"
Re-Release "Why Do Brains Dream" Oct 5, 2026 3133 This week we reach into the archive for one of the most popular episodes of Inner Cosmos. Why do brains dream, and why are dreams so bizarre? Why doesn't your clock work in your dreams? And even though you spend much of your working day looking at your cell phone and computer – why do they almost never make appearances in your dream content? Is dream content the same across cultures and acro
Ep173 "Why Do We Have Emotions?" with Robert Kurzban

What happens when ancient emotions meet dating apps and like buttons? Does the intensity of a feeling decide which part of you takes control? Can understanding an emotion loosen its grip? Today we sit down with evolutionary psychologist Robert Kurzban to understand the logic behind the our
Ep172 "Can You Quantify Yourself to Improve Health?" with Michael Snyder
Ep172 "Can You Quantify Yourself to Improve Health?" with Michael Snyder Sep 21, 2026 3780 Can your smartwatch detect subtle changes before you feel them? Might a continuous glucose monitor pick up on things you didn’t know about yourself? Could a drop of blood map your future health? Why does your personal baseline matter more than a population average? Could AI decode the massive signaling networks of your body? Does seeing your own data change your behavior? Join Eagleman with&
Ep171 "Why Do Some Urges Feel Irresistible?" with Paige Gordon
Ep171 "Why Do Some Urges Feel Irresistible?" with Paige Gordon Sep 14, 2026 2789 Why do two people facing the same choice feel different urges? How much effort hides behind resisting a cookie? Why can the brain keep wanting something long after pleasure fades? Can a molecule crank down the volume of your internal radio? Does a biological understanding of behavior reduce responsibility, or does it deepen compassion? And how would your life change if your loudest urge went quiet
Ep 170 "Will Mars Create a New Species of Human?" with Scott Solomon
Ep 170 "Will Mars Create a New Species of Human?" with Scott Solomon Sep 7, 2026 2931 What happens when we start birthing babies on Mars? Might a Martian human become unable to survive on Earth because of differences in microbes and gravity? How much of your body is shaped by the details of this planet? Will radiation accelerate human evolution on Mars? Could living on Mars eventually create a new species of human? Could Mars change the way humans dream? Would a Martian child find
Ep169 "What Is Claude Thinking But Not Saying?" with Jack Lindsey
Ep169 "What Is Claude Thinking But Not Saying?" with Jack Lindsey Aug 31, 2026 4869 Is AI thinking things it never says aloud? How would we know if a large language model were having a subjective experience? Is there a way to read the 'thoughts' of an LLM? Human brains seem to have a 'global workspace' -- what would it mean if we discovered that AI has something similar? Can you reach inside an LLM to change one of its 'thoughts'? Join Eagleman with Anthropic interpretabilit

As we enter an AI-powered world, when might we choose an AI leader? Will your grandchildren ever vote for a human president, who comes with a political party & the weaknesses of a human, or will they vote for a system that has a jaw-dropping capacity to extract patterns from vast rivers of data, simulate millions of possible
Ep167 "What Happens With Stone Age Brains + Godlike Tools?" with Steven Kotler

Ep166 "Could the Next Brain Interface Get Sprayed Up Your Nose?" with Tetiana Aleksandrova & Scott Meek
Ep166 "Could the Next Brain Interface Get Sprayed Up Your Nose?" with Tetiana Aleksandrova & Scott Meek Aug 10, 2026 2876 A brain computer interface (BCI) is any technology that allows you to connect your 3 pounds of wetware to a computer. But instead of implanting electrodes via neurosurgery, might the next revolution in BCIs come from something very small, like nanoparticles? Would this allow us to spy on millions (or billions) of neurons talking at once -- and could we do so without opening the
