There's an invisible super-pollutant heating up the planet — but it's surprisingly easy to reduce, if we try. Revealing how methane contributes (way) more in the short term to global warming than carbon dioxide, chemical engineer Daniel Zavala-Araiza highlights the emerging technologies and bold new policies that are part of a worldwide effort to hold oil and gas companies accountable for polluting our skies with this harmful gas. ...

AI is transforming the way we work — could it also reshape what makes us human? In this quick and insightful talk, evolutionary anthropologist Sarah Blaffer Hrdy explores how the human brain was shaped by millions of years of shared childcare and mutually supportive communities, asking a provocative question: If robots help raise the next generation, will we lose the empathy that defines us?

Industrial manufacturers spend a huge amount of energy generating heat to make everyday materials and objects, like cement, steel, and paper. And since most companies use fossil fuels to reach these high temperatures, industrial heat accounts for 20% of our annual global carbon pollution. Thankfully, this is where a century-old technology comes in. Rachel Yang explores how heat batteries work. [Directed by Sofia Pashaei, narrated b...

Generative AI is built on three key resources: people, compute and data. While companies invest heavily in the first two, they often use unlicensed creative work as training data without permission or payment — a practice that pits AI against the very creators it relies on. AI expert Ed Newton-Rex has a solution: licensing. He unpacks the dark side of today's AI models and outlines a plan to ensure that both AI companies and creato...

Moore’s Law states that every 1 to 2 years the number of transistors that can fit on a given size computer chip will double. Thanks to this law, chips have gotten smaller, faster, more efficient, and cheaper. But today, there are four key problems that trip up this trend, potentially ending Moore’s Law and fundamentally changing how computing progresses. Sajan Saini and George Zaidan investigate. [Directed by Jeff Le Bars, JetPropu...
