The Secret Nazi Past and Billionaire Future of U.S. Space Innovation with Jordan Bimm

Few ideas have gripped the public imagination quite like the idea of the “psychopath.” From Hollywood thrillers to true-crime podcasts, popular culture has led us to believe that psychopaths are dangerous and biologically distinct from the rest of us. But what if almost everything we think we know about them is wrong?In this episode, we talk with Rasmus Rosenberg Larsen, an Assistant Professor of Forensic Epistemology at the University of Toronto and author of "Psychopathy Unmasked," whose research is challenging the very foundation of psychopathy as a diagnosis. Larsen explains how the term “psychopath” is relatively new, dating to the Ted Bundy trial in the 1970s, and how TVs and movies have skewed our understanding of the “psychopath.” He discusses psychopathy tests, their impact on the criminal justice system—and what the latest science reveals about the minds we’ve long misunderstood.

For decades, neuroscience has promised breakthroughs in treating conditions like depression, schizophrenia, and Alzheimer’s. Yet despite powerful technologies and billions invested, progress has been frustratingly slow. Why?On this episode of Big Brains, we talk with Nicole Rust, neuroscientist at the University of Pennsylvania and author of Elusive Cures. Rust argues that the traditional “domino” view of the brain—where one broken piece can simply be fixed—has held us back. Instead, she says we need to embrace the brain’s true nature: a complex, dynamic system more like the weather than a machine.We explore why treatments so often fail, what makes mood such a scientific mystery, and whether a new era of brain research—powered by models, feedback loops, and fresh ways of thinking—can finally deliver the cures that have long eluded us.

Billions of years ago, Mars may have looked less like the barren red desert we know today and more like Earth—with a blue sky, flowing rivers, and even seas. What happened to turn a once-habitable world into the frozen, lifeless planet we see now?On this episode of Big Brains, University of Chicago geophysical scientist Edwin Kite takes us on a journey through Mars’ hidden past. From evidence of a lost carbon cycle to theories about ancient climate swings, Kite’s research is rewriting the story of the Red Planet. But it’s not just about the past—his work is also at the forefront of a provocative question: could humanity one day terraform Mars and make it a living world again?

We’re living in an attention economy—and most of us are broke. But what if the secret to restoring your focus, improving your mental health, and even reducing crime rates wasn’t found in an app or a pill, but in a tree?In this episode, we speak with University of Chicago psychologist Marc Berman, whose research on “soft fascination” and nature’s cognitive effects is reshaping how we think about everything from urban planning to depression treatment. From groundbreaking hospital studies to surprising results with plastic plants, Berman’s work uncovers the deep—and often invisible—power that natural environments hold over our minds and bodies.Whether you're a city planner, a parent, or just someone feeling mentally fatigued, this conversation may just change the way you think about a walk in the park.

We’ve long marveled at how efficiently plants convert sunlight into energy—but no one guessed they were using quantum mechanics to do it.In this episode, we speak with Greg Engel, a pioneering biophysicist at the UChicago Pritzker School of Molecular Engineering and the Department of Chemistry who helped launch the field of quantum biology. Engel explains how plants and bacteria evolved to exploit quantum effects for photosynthesis—and how understanding these systems could spark a revolution in quantum sensing, medicine, and neuroscience.Engel’s team has already built quantum sensors inspired by nature’s designs, with the potential to transform how we detect disease, develop drugs, and even read neural signals. The ultimate goal? A new era of quantum medicine, powered by the weird and wonderful physics found in leaves. A new large gift is helping that mission along by establishing The Berggren Center for Quantum Medicine and Biology at The UChicago Pritzker School of Molecular Engineering, partnering with BSD, UC Medicine and others.

You’ve heard of plastic polluting oceans. But what if it’s polluting you—your brain, your reproductive system, even your unborn children?In this eye-opening episode, we speak with Prof. Matthew Campen, a scientist at the University of New Mexico, whose latest studies have uncovered evidence of microplastics in placentas, reproductive organs and brains of humans—particularly in the frontal cortex, where decision-making and personality live.We explore how these plastic particles are entering our bodies (hint: it’s not just your water bottle), what they might be doing to us, and why scientists are just beginning to understand the true scope of the issue. From declining sperm counts to potential links with dementia, this episode asks a critical question: Are microplastics the next big public health crisis? Hosted by Simplecast, an AdsWizz company.

One of the benefits of producing this podcast at the University of Chicago is that there are often events on campus that bring in not just one Big Brain, but many in order to find answers to the some of the most complex problems of our time. I recently had the pleasure of hosting one such event on artificial intelligence that we want to share with you today. It was part of the Graham School’s Leadership & Society Initiative Symposium, examined how AI could change everything and, more importantly, whether it should.Artificial intelligence is evolving faster than most of us can keep up with—and its impact is already reshaping our lives, from the hospital to the courtroom to the art studio. Is AI moving too fast? Are we focusing on the wrong questions? And what comes after today’s generation of models? It’s a candid, complex, and eye-opening conversation you won’t want to miss.

For a more than a century, the Food and Drug Administration has worked to protect public health. In his research, Harvard University physician-researcher Jerry Avorn has examined how the FDA’s once-rigorous gold standard approval process has been affected by a powerful shortcut known as the Accelerated Approval Program—originally designed for desperate AIDS and cancer patients. He says that change in the 1990s has allowed more than half of all new drugs onto the market before drug companies have proven they actually help people.In his new book Rethinking Medications: Truth, Power and the Drugs We Take, Avorn cites numerous examples: from a cold medicine that doesn’t de-congest to billion-dollar cancer treatments that only shrink lab results to the controversial Alzheimer’s drug Aduhelm—approved despite no clear cognitive benefits. In this episode, Avorn explores whether some prescriptions in your medicine cabinet are safe, effective and worth the money. Hosted by Simplecast, an AdsWizz company.

Prof. James Evans, a University of Chicago sociologist and data scientist, believes we’re training AI to think too much like humans—and it’s holding science back.In this episode, Evans shares how our current models risk narrowing scientific exploration rather than expanding it, and explains why he’s pushing for AIs that think differently from us—what he calls “cognitive aliens.” Could these “alien minds” help us unlock hidden breakthroughs? And what would it take to build them? Hosted by Simplecast, an AdsWizz company. See pcm.adswizz.com for information about our collection and use of personal data for advertising.
