Big Brains

The internet and social media have transformed the way in which we hear and understand music today—and online communities and platforms from YouTube to TikTok have changed how music circulates and ultimately goes viral. Why do some pop stars have more success creating hit songs and building online following than others?In this episode, we speak with Paula Clare Harper, a musicologist and assistant professor at the University of Chicago. Harper co-edited the book Taylor Swift: The Star, The Songs, The Fans, which explores the online musical cultures that produced and propelled the image of megastar Taylor Swift. Harper unpacks how gendered narratives around "the fangirl" continue to influence which musical practices we take seriously—and how studying music on the internet helps us understand contemporary cultural power.

Can you imagine a world in which a wearable device, like a smartwatch, could move your fingers to strum the guitar or play the drums? That kind of technology is part of the innovative research coming out of the Human-Computer Integration Lab at the University of Chicago, led by renowned computer scientist Pedro Lopes. His lab is developing a new generation of gadgets that use haptics (or tactile sensations like the buzz of your smartphone) to move your body, replicate your sense of smell and even make you feel things.In this episode, Lopes explores the potential of wearable devices to transform our future as well as brain-computer interfaces that are being developed by companies like Elon Musk’s Neuralink that directly into the body.

More and more women in the United States are saying no to motherhood. In 2023, the U.S. fertility rate reached the lowest number on record. But the idea of non-motherhood is actually not a new phenomenon, nor did it come out of the modern feminist movement. For centuries, women have made choices about limiting births and whether or not to become mothers at all. This history is documented in a new book, "Without Children: The Long History of Not Being a Mother," by University of Chicago Assistant Instructional Professor Peggy O'Donnell Heffington.Heffington writes about the historic trends of non-motherhood as well as the modern factors that are playing a role in women's choices to not have children today — from lack of structural support in the workplace, to a national law for paid maternity leave, and the sheer lack of affordability. She writes that if these trends continue, American millennials could become the largest childless cohort in history. Hosted by Simplecast, an AdsWizz company.

What does it mean to see beneath the surface — of the human body, the brain, or even the universe itself? In his new book, The Future of Seeing: How Imaging Is Changing Our World, Prof. Daniel Sodickson of NYU explores the future of imaging: How technology is transforming not just medicine, but our very ways of perceiving the world. With the rise of AI-driven “digital vision,” Sodickson, a pioneer of MRI innovation, argues that imaging is no longer just a diagnostic tool — it’s becoming a new language of discovery.In this conversation, Sodickson explores the promises and pitfalls of this promising new technology. Reflecting on the history of scientific discovery, we examine what the next generation of imaging might reveal about life itself. Hosted by Simplecast, an AdsWizz company.

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.
