NOVA Presents

Dennis Whyte studies the physics that powers every star in the universe, and he says it can power your house, too. Now the CEO of the UK’s Atomic Energy Authority and nuclear scientist at MIT, Dennis joins Hakeem to break down what fusion actually is, why it packs 10 million times the energy density of gasoline, and who is making the biggest investment in this massive energy field. Dennis unpacks the surprisingly direct link between a society's energy use and its economic prosperity, and reveals why fusion might change everything.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. 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.

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 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 besting children in “the peanut puzzle” to baboons that seemingly sense how to travel together, there’s lots to learn.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.

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.

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? Federico shares how he secured quantity and quality data and the messages dogs want to share.
