Wendy Suzuki hopes you have anxiety—good anxiety. She thinks that feeling you try to avoid could actually be your edge! Wendy joins Hakeem to explore how anxiety can be harnessed, rather than eliminated, and how it connects to two other powerful forces shaping your brain: exercise and human connection. What’s happening in that surge of stress—or in the “neurochemical bubble bath” after a hard run? Can you really train your brain to use it differently? And what do oxytocin, prairie voles, and decades of research reveal about why social bonds may be the most powerful force shaping our health, happiness, and longevity.  Make sure to subscribe now so you never miss an episode.

She is the author of several books, including Good Anxiety: Harnessing the Power of the Most Misunderstood Emotion, and is a widely sought-after speaker on brain health, anxiety, and human performance.

Wendy Suzuki says the key to a beautiful brain is friendship, and she joins Hakeem to discuss why human connection can extend your life. By studying certain animals, like prairie voles who develop intense love bonds, we can understand what’s going on in our heads when we connect with others. Hard data and personal stories show, the power of friendship is a shockingly important part of a healthy lifestyle.

Wendy Suzuki says just 10 minutes of movement can change your brain.But how? What’s actually happening in your head during a walk—or a workout—and why does it matter so much? Wendy joins Hakeem to unpack the science of exercise and the brain, from chemical surges to lasting rewiring. Plus: how do meditation, cold showers, and your environment really change your brain?

Neuroscientist Wendy Suzuki thinks your anxiety could be a superpower. What if you stopped trying to shut it down—and started using it? Wendy joins Hakeem to reframe anxiety as fuel, not flaw, and shows how to turn that rush of stress into focus and action. Plus, Wendy gives some hot takes on anxiety hacks like fidget spinners and weighted blankets.

Steve Brusatte has the dirt on dinosaurs and joins Hakeem to trace the full 100-million-year history of the tyrannosaur dynasty, the asteroid that ended it, and the remarkable truth that dinosaurs never actually disappeared. One small lineage survived to become every bird alive today, and Steve walks through the long and contested scientific history of how we came to understand that connection. He also shares what it was like to serve as the official paleontology consultant on the Jurassic World films, and how to find the balance between science and cinema.

He is the author of several acclaimed books, including The Rise and Fall of the Dinosaurs and The Story of Birds, and has served as a paleontology consultant on the Jurassic World film franchise. He will be featured in NOVA's upcoming five-part documentary series Evolution, coming fall 2026.

Steve Brusatte, a real paleontologist, contributed to the Jurassic World franchise, but what really happens when science meets cinema? In this episode, Steve joins Hakeem to discuss what that paleontology consultant role actually looks like, how he navigates the tension between scientific accuracy and Hollywood storytelling, and what the films have gotten increasingly right about dinosaurs over the years. They also dig into which documentaries offer the most accurate modern picture of dinosaurs, how AI is beginning to reshape paleontology, and what Steve would love to see in a future Jurassic film.

Steve Brusatte knows every bird today is a living dinosaur, and as a paleontologist, he can tell you how that happened. Steve joins Hakeem to walk through the catastrophic asteroid impact 66 million years ago that ended the age of T. rex, and to explain why one small, beaked, seed-eating lineage was the only branch of the dinosaur family tree to survive. He traces the long and contested scientific history of the bird-dinosaur connection and the discovery by Chinese farmers in the 1990s that finally settled the debate. The age of dinosaurs did not end with the asteroid. It transformed. Make sure to subscribe now so you never miss an episode.

Steve Brusatte says T. rex wasn’t always the king, and as a paleontologist, he has spent his career uncovering how it got to the top of the food chain. Steve joins Hakeem to trace the full 100-million-year history of the tyrannosaur family, from its surprisingly small and nimble origins to the bone-crushing apex predator that ruled the end of the Cretaceous. They discuss how T. rex was not just a creature of brawn but also of remarkable intelligence, with keen senses of smell and hearing that made it the ultimate predator of its time. Along the way, they explore the diversity of tyrannosaur cousins including the long-snouted “Pinocchio rex” discovered on a Chinese construction site, and how shifting climates, mass extinctions, and continental drift shaped the dynasty's rise over millions of years.

David Kaiser thinks the dark matter puzzle is getting closer to being solved.  Nearly a century of observations, from galaxy clusters to the cosmic microwave background, have built a compelling case for dark matter's existence, but in recent years, the leading candidates for this mysterious matter have been coming up short..  Enter black holes. Tiny ones. David explains how so-called primordial black holes that formed in the first moments after the Big Bang could possibly be all our dark matter… if they exist at all. Fortunately, this is a testable theory, and David explains the exciting new experiments that could potentially lay this cosmic mystery to rest.  Make sure to subscribe now so you never miss an episode.

David Kaiser thinks a good place to hunt for tiny black holes might be… Mars? How do you detect something microscopic, invisible, and speeding through space? Primordial black holes have long eluded astrophysicists—if they exist at all. But the hunt is heating up. David joins Hakeem to explore how scientists are combing through old data and designing new experiments that could finally catch one of these elusive objects—and possibly not only solve the century-old mystery of dark matter, but also confirm the existence of Hawking Radiation. And, yes, he explains why Mars might hold the key.  Make sure to subscribe now so you never miss an episode.
