NOVA Presents

We can’t predict earthquakes, but we can beat them.Geophysicist breaks down what actually keeps people alive when the ground starts shaking. From flexible buildings to early warning systems, John walks Hakeem through what separates cities that survive major earthquakes from cities devastated by them, and why the difference often comes down to policy not physics.Learn more about NOVA and visit our YouTube channel.--------------------------Guest Bio:John Shaw is the Harry C. Dudley Professor of Structural and Economic Geology at Harvard University, where he also serves as Vice Provost for Research. A structural geologist and applied geophysicist, he studies the faults deep beneath our feet, with research spanning earthquake hazards, energy systems, and carbon storage.

There is a near-limitless energy source to power our world, and it may be almost here. Dennis Whyte shares with Hakeem that we're closer than ever to bottling the power of the sun. He would know. He’s now the CEO of the United Kingdom’s Atomic Energy Authority and a nuclear scientist at MIT. What happens when we finally unlock nuclear fusion, the same energy source that powers the sun? What even is fusion? How does it work, and why are scientists now so close to building commercially viable fusion systems that could put power on the grid? From fusion fundamentals, to the future of energy, to interstellar space travel, Dennis and Hakeem deliver a big conversation on an innovation that could change everything.

He co-founded Commonwealth Fusion Systems, the MIT spinout building a compact fusion reactor using record-breaking superconducting magnets, and is now the CEO of the United Kingdom's Atomic Energy Authority.

Dennis Whyte helped spark a multi-billion-dollar industry from a spool of tape. The nuclear scientist and entrepreneur explains the nitty gritty of nuclear fusion through the multitude of businesses that are chasing nuclear fusion. Dennis walks Hakeem through the origin story of Commonwealth Fusion Systems, the company he co-founded from a class assignment, and reveals how a new superconducting material discovered in the 1980s finally made compact fusion possible.Learn more about NOVA and visit our YouTube channel.--------------------------Guest Bio:Dennis Whyte is the Hitachi America Professor of Engineering at MIT and former director of the Plasma Science and Fusion Center.

Federico Rossano convinces Hakeem that animals have a lot more to say than we've given them credit for. The cognitive scientist shares the origin story behind his record-breaking study of talking dogs, the evidence that some pets may understand more than a human toddler, and what primates reveal about the roots of communication itself.Learn more about NOVA and visit our YouTube channel.Federico Rossano is an Associate Professor of Cognitive Science at UC San Diego and director of the Comparative Cognition Lab, where he studies communication and social cognition across humans, primates, dogs, and cats. He leads the world's largest study of button-trained pets, and his research is featured in the NOVA documentary Can Dogs Talk?

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 NOVA and visit our YouTube channel.--------------------------Guest Bio:Federico Rossano is an Associate Professor of Cognitive Science at UC San Diego and director of the Comparative Cognition Lab, where he studies communication and social cognition across humans, primates, dogs, and cats.

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 remarkable story of the Denisovans, a species shrouded in mystery and identified first not from a skull or skeleton, but from a single finger bone.

She specializes in human evolution and has conducted fieldwork in some of the world's most dangerous and remote regions in search of fossil evidence of our earliest ancestors. She is a TED speaker and has appeared in numerous science documentaries, including hosting NOVA and BBC’s five-part series HUMAN, available on the PBS App and NOVA’s website.

Daniela Rus brings robots and AI together, and as a computer scientist and roboticist at MIT, she's here to set the record straight. She's not just studying AI from the outside. She's building it, and finding ways to make everyday life better. Daniela joins Hakeem to pull back the curtain on what AI actually is, how it really works, and where it is genuinely headed. What happens when AI leaves the cloud and moves into your phone, your car, and even your body? And what does a tiny worm with 302 neurons have to do with the future of machine intelligence? From the history of AI to so-called “liquid networks,” self-driving cars, humanoid robots, and an origami surgeon you can swallow, this conversation covers the full scope of what MIT's most ambitious minds are building right now.Learn more about NOVA and visit our YouTube channel.Daniela Rus is a computer scientist and roboticist at MIT, where she serves as Director of the Computer Science and Artificial Intelligence Laboratory (CSAIL). Her research focuses on the science and engineering of autonomy, including the development of new AI models, and physically intelligent systems. She is the co-founder of Liquid AI, a startup bringing energy-efficient on-device AI models to real-world applications.

Daniela Rus has built a robot you can swallow, and that is one of the less surprising things her lab is working on. At MIT's CSAIL, she is leading research at the frontier where artificial intelligence meets the physical world, and the results are unlike anything people have imagined. Daniela joins Hakeem to explore what it will really take for machines to move, reason, and interact the way humans do. Why are today's humanoid robots mechanically impressive but intellectually limited? What is the difference between physical AI and embodied intelligence, and why does it matter? From origami surgeons, to robots inspired by the octopus, this is a conversation about the machines of the futureLearn more about NOVA and visit our YouTube channel.--------------------------Guest Bio:Daniela Rus is a computer scientist and roboticist at MIT, where she serves as Director of the Computer Science and Artificial Intelligence Laboratory (CSAIL).
