We spoke with Prof. Dougla...

What if the way you relate to others isn’t fixed—but fundamentally changeable? In this episode, we speak with psychiatrist and neuroscientist Amir Levine, who is an Associate Professor of Clinical Psychiatry at Columbia University Medical Center. He's the author of the best-selling book Attached, which examined how people’s attachment styles—from secure to anxious to avoidant. In his new book, Sec...

What if we could predict the world’s most dangerous weather events—not days, but weeks in advance? Extreme events like heat waves, hurricanes, and floods cause massive loss of life and billions in damage, but they’re also some of the hardest events for traditional weather forecasting to predict. In this episode, Assoc. Prof. Pedram Hassanzadeh of the University of Chicago explains why forecasting...

In recent years, a judge in one state had gained the power to halt policies across the entire United States. Known as nationwide or universal injunctions, these actions have become one of the sweeping tools in the federal court—affecting cases ranging from student loan forgiveness to environmental policies to birthright citizenship. How did universal injunctions become such a central feature of mo...

Artificial intelligence may live in “the cloud,” but its footprint is firmly on the ground. As AI systems grow more powerful, the data centers that train and run them are consuming massive amounts of land, water and electricity—as well as reshaping regional power grids. What does this surge in demand mean for the environment, energy infrastructure, and the future of innovation? In this episode, we...

When a two-year-old boy suffered a catastrophic injury that severed the connection between his skull and spine, doctors across Europe told his family there was no hope. His spinal cord was completely severed, and the injury was not considered survivable. But University of Chicago neurosurgeon Mohamad Bydon saw a possibility. In this episode of Big Brains, Dr. Bydon walks us through the extraordina...

In today’s world, our brains are overloaded with information, making it hard to focus and remember. But what are the true limits of the human mind—and why do they exist? And why are some people seem so much better than remembering things than others? In this episode, we talk with with Edward Awh, a cognitive neuroscientist and professor of psychology at the University of Chicago. Whose lab studies...

The process of understanding who we are is a lifelong journey for many of us. For two decades, that question has been one that University of Chicago scholar Eric Oliver has asked his students in class—and inspired him to write a new book called "How to Know Your Self: The Art & Science of Discovering Who You Really Are." A renowned political scientist, Oliver draws upon science, philosophy, psycho...

What if we could precisely measure a cell at its most fundamental level? In this episode, we talk with the University of Chicago scientist Peter Maurer about how he and his colleagues made the breakthrough discovery of turning a protein found in living cells into the first biological quantum bit, also known as a qubit. Maurer explains how quantum systems—once thought to be too fragile for real-wor...

We've all heard the phrase "Manifest Your Destiny" when it comes to wanting a new promotion, figuring out a new career path or just trying to achieve that long-term goal. It turns out that the act of manifestation is not merely pseudoscience—it actually has a body of research in neuroscience to back it up. James Doty was a clinical professor of neurosurgery at Stanford University, and founder and...

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 assistan...

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 s...

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...

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...

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...

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...

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...

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 e...

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 exploi...

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,...
