Secret Language of Apes

NOVA Presents ·

2026/09/22

Federico Rossano says the secret to speaking with apes is trust. For primates, the world is full of high-stakes friends and foes, and of course, there are always predators to worry about. Our closest relatives see the world a little differently than we do, and that can teach us a lot about our own communication. Federico is a cognitive scientist who questions the assumptions beneath human conversations, and in this episode, he shares lessons from the animal kingdom with Hakeem. From apes

What Are Dogs Saying?

NOVA Presents ·

2026/09/17

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 and believes we are close to learning important lessons from our canine companions.Learn more about

How to Save The “Doomsday Glacier”

NOVA Presents ·

2026/09/10

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 improbable journey from 9/11 first responder to two of the world's top science institutions. It's a

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 his experience in the military informs his scientific mission planning and decision making. Learn more

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 lays out a plan to investigate if they can truly deploy it on the world's most precarious glacier. Learn

The Glacier That Could Change the World

NOVA Presents ·

2026/09/01

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 our future. How certain is that “doom,” and how fast could it happen? They nerd out about what happens as

The Hidden Math Behind Everything

NOVA Presents ·

2026/08/27

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 quite predict, Jordan and Hakeem trace math's fingerprints across physics, language, and daily life in

Certainty Is Overrated

NOVA Presents ·

2026/08/25

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 and what's fundamentally unknowable, why hurricanes and earthquakes are "certain uLearn more about NOVA

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 multi-dimensional space, and what can a 19th-century novella about a talking square teach us about

Rethinking Neanderthals

NOVA Presents ·

2026/08/06

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 about their inner lives, and if we would even recognize one walking around today. They also dig into the

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 Indonesia to the mysterious Denisovans of East Asia, the world was very different, and new research
