What sitting all day does to your brain and body | Keith Diaz | Your Body on Tech
Can a five-minute walk change how you feel all day? Exercise scientist Keith Diaz shows how your body is built for the kind of movement that modern life has quietly erased — and suggests something refreshingly doable: making time for small doses of movement sprinkled throughout the day, as a way to boost your brain and body. And stick around after his talk for a deep dive conversation with our guest host for the week, author and podcaster Manoush Zomorodi, into the ideas he shared on stage and beyond. This is episode one of a seven-part series airing this week on TED Talks Daily, where Manoush — and the seven speakers she curated for TED2026 — explore how you can live a healthier life in our high-tech era. To hear more from Manoush, listen to TED Radio Hour wherever you get your podcasts. Check out her new book, Body Electric, to learn more about the hidden health costs of the digital age.

Alternative Future (#1): AI is changing how we talk and think. How can we stop it? with Adam Aleksic and Advait Sarkar

Alternative Future (#4): The food that fertilizes itself | Giles E.D. Oldroyd
Could the key to a sustainable food system already be growing in the world’s farms? Plant scientist Giles E.D. Oldroyd explores how a special quirk of soybean plants allows them to naturally partner with networks of fungi and bacteria to access essential nutrients in the air and soil — eliminating the need for synthetic fertilizers. He shows how harnessing these microscopic powerhouses could help scientists rewire crops to make their own fertilizer, reducing pollution, increasing yields and improving livelihoods for smallholder farmers.
