In 2022, physicist Tammy Ma and the team at Lawrence Livermore National Laboratory achieved a scientific breakthrough decades in the making: fusion ignition, or the combining of two atoms to generate more energy out of a reaction than was put in — recreating on Earth the same process that powers the Sun. She explains how they used a giant laser (way, way bigger than you're thinking) to catalyze this reaction and shares a vision for how this technology could change the world by creating limitless clean energy.

2024 is the biggest election year in modern history, with over 50 countries going out to the polls across the globe. And artificial intelligence has fully seeped into global politics – from deepfakes to AI bots that can ingest thousands and thousands of documents to make policy decisions. Bilawal talks with journalist Vittoria Elliot, who’s been leading on WIRED’s AI Elections Projects, to discuss how AI is reshaping the political landscape in surprising ways. The two explore the good, the bad, and the downright bizarre – and share what the U.S. can learn from other countries to adapt and critically engage with "the new normal."

Meet MethaneSAT: the satellite circling Earth right now to track global emissions from methane: a highly potent, short-term greenhouse gas. Environmental advocate Millie Chu Baird details the heat-trapping side effects of a planet full of methane — and explains why understanding where it comes from and taking steps to reduce it is the single most important thing we can do to affect climate change in our lifetimes. MethaneSAT is part of the Audacious Project, TED's initiative to inspire and fund global change. After the talk, Sherrell expands on what this powerful tech could mean for humanity.
