How To Use Nature To Restore Your Focus, with Marc Berman
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.

Could Plants Unlock Quantum Medicine’s Potential? with Greg Engel
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.

How Microplastics Are Invading Our Bodies, with Matthew Campen
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?

Inside the AI Debate: Hope, Hype, Or Harm? A Big Brains Panel Weighs In
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.
Big Brains explores the groundbreaking research and discoveries that are changing our world. In each episode, we talk to leading experts and unpack their work in straightforward terms. Interesting conversations that cover a gamut of topics from how music affects our brains to what happens after we die.
