What Are Dogs Saying?
Federico Rossano caught dogs doing something that looks a lot like telling jokes. The cognitive scientist shares what he learned from speaking with dogs. Dogs can smell, hear, and in some ways see better than humans. So why wouldn’t they have something interesting to say if they could speak? Federico has found a dog's mind may be closer to a human toddler's than anyone previously believed
How Dogs Talk
Federico Rossano didn't care about talking dogs until science made it impossible to ignore. The cognitive scientist joins Hakeem to reveal how a viral social media trend turned into the largest citizen-science study of animal communication ever conducted, tracking over 10,000 dogs and 700 cats across 47 countries. But how can you trust a study done by volunteers from around the world? Fed
Full Interview: How to Save The “Doomsday Glacier”
Brent Minchew could have a plan to stop Thwaites Glacier, AKA the “Doomsday Glacier”, cold in its tracks. That’s good news because if this one glacier slips into the sea, it could flood coasts across the planet. The Caltech glaciologist covers what makes the “Doomsday Glacier” the single biggest wild card in sea level rise, the simple idea that could freeze it back to its bed, and his own
From Marine One to Mission Antarctica
Brent Minchew responded to the Pentagon on September 11th, 2001. Before he was a glaciologist at Caltech, he was a marine aboard the Marine One presidential helicopter and was one of the first on sight after the deadly attack. Brent joins Hakeem to trace his unlikely path from a working-class upbringing in Texas to a career studying the world's most extreme ice sheets. And he traces how h
Glacier Rescue
Brent Minchew has a plan that could stop the “Doomsday Glacier” in its tracks, and we don’t even need new technology to do it. The Caltech glaciologist returns to unveil an intervention that could save coasts around the world: refreezing Thwaites Glacier to its own bedrock using passive principles of physics. Brent walks Hakeem through the natural process that slows glaciers down, and la
The Glacier That Could Change the World
Brent Minchew is an expert on the glacier that could devastate the world’s coastlines. As a glaciologist at Caltech, he's spent his career tracking Thwaites Glacier, AKA the "Doomsday Glacier." It’s roughly the size of Florida and already losing 50 billion tons of ice a year. Brent joins Hakeem to break down what scientists know – and don’t know – about the glacier that could determine ou
Full Interview: The Hidden Math Behind Everything
Jordan Ellenberg tells Hakeem that math isn't just about numbers. It's about everything. The mathematician and bestselling author shares how AI models are trained through trial and error, why geometry secretly governs everything from family trees to statistical correlation, and why uncertainty, not certainty, is the true language of the universe. From new dimensions to hurricanes we can't
Certainty Is Overrated
Jordan Ellenberg finds mathematical certainty overrated. Calming our fear of the unknown, the mathematician joins Hakeem to explore why math, contrary to popular belief, is less about proof and more about probability. He traces uncertainty's surprisingly recent arrival in mathematical history and its deep ties to quantum physics. Jordan also unpacks the difference between what's unknown a
Next Dimension Geometry
Jordan Ellenberg says geometry isn’t about shapes. It’s about distance. In a tour of geometry far stranger than anything from high school, the mathematician breaks down how our ancient understanding of triangles evolved into the invisible architecture behind AI, family trees, and human relationships. Minds expand as we ask why the "closeness" between two ideas is a literal angle in a vast
AI’s Hidden Math
Jordan Ellenberg has good news: artificial intelligence is just math you can actually understand. The mathematician joins Hakeem to pull back the curtain on how large language models really work, revealing that the "miracle" of AI is closer to trial and error scaled up billions of times than anything resembling thought. Jordan breaks down why the process works so well, how every word beco
Full Interview: Hobbits, Neanderthals, and Dragon Man
Ella Al-Shamahi explores what it means to be human. She reveals the surprising truth that our ancestors shared the planet with at least seven other human species as recently as 50,000 years ago. Ella and Hakeem dig into Neanderthal culture and the mysterious Denisovans who were identified from a single finger bone. Then Ella shares something more personal: her own journey from creationist
Creationist to Evolutionary Biologist
Ella Al-Shamahi set out to disprove the theory of evolution. Now she’s one of its greatest advocates. In this deeply personal conversation, Ella tells Hakeem her story. She started university as an avid creationist missionary with the intention of disproving evolution, and then her world started to fall apart. This candid conversation covers what the journey from creationist to paleoanth
Rethinking Neanderthals
Ella Al-Shamahi thinks Neanderthals have a reputation problem, and the science backs her up. For decades, the word "Neanderthal" has been shorthand for something primitive and brutish. But the archaeological record tells a more nuanced story. Ella joins Hakeem to explore what we actually know about our closest ancient relatives: how they looked, how they lived, what their culture reveals
Real Hobbits?
Ella Al-Shamahi says the iconic picture of human evolution is all wrong. She joins Hakeem to take apart the conventional image of the straight-line march of evolution from ape to modern human. The fossil and DNA record tells a far more complex story. As recently as 50,000 years ago, our ancestors shared the planet with at least seven other human species. From the small-statured Hobbits of

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
Your Brain Needs Friends
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 h
Neuroscience of Exercise
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?Learn more about NOVA

Are Black Holes Dark Matter?
David Kaiser thinks tiny black holes from the dawn of time could be the solution to the dark matter puzzle. David joins Hakeem to discuss primordial black holes, tiny objects that may have formed in the first fraction of a second after the Big Bang. First proposed by Stephen Hawking more than 50 years ago, this hypothesis requires no new physics and no new particles, making it one of the
