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.

    Manoush Zomorodi, host of TED Radio Hour, takes over as guest host ofTED Talks Daily this week to answer a timely question: What does it mean to be human right now, as technology reshapes everything around us? She brings together seven thinkers — scientists, doctors, parents, an artist — to wrestle with how we stay connected to ourselves, and our bodies, in a world that keeps pulling us away. First up, Manoush is joined by Elise Hu to dig into the ideas that are going to be explored this week. They discuss her new book, Body Electric, which explores the hidden health costs of our sedentary lifestyle, and what we can all be doing to reverse the damages.
  • Alternative Future (#1): AI is changing how we talk and think. How can we stop it? with Adam Aleksic and Advait Sarkar

    34:06|
    Algorithms and AI don’t show us reality, but that doesn’t stop people from treating ChatGPT and online bots as our personalized therapists, travel planners, and editors. In this episode, Sherrell is sharing two talks on how AI is changing the way we’re influenced. From shaping our language to becoming “middle managers of our own thoughts,” these speakers ask what happens when we offload critical thinking to a machine.Talks featuredWhy are people starting to sound like ChatGPT? | Adam AleksicHow to stop AI from killing your critical thinking | Advait Sarkar

    Faced with the realities of current crises, it’s easy to assume our world is headed in a bleak direction. But there’s good reason to be hopeful— with developments in science and technology, a positive future is more viable than ever before. So, what if the future was awesome?

    Is space the “final frontier” — or the perfect place to revolutionize life on Earth? Space architect Ariel Ekblaw reveals how self-assembling structures could build orbiting real estate in space dedicated to solving humanity’s greatest dilemmas on Earth, leading to scientific and medical breakthroughs only possible in zero gravity.
  • Alternative Future (#4): The food that fertilizes itself | Giles E.D. Oldroyd

    14:46|
    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.
  • Alternative Future (#5): Who owns the internet of the future? | Ordinary Things

    21:12|
    The emergence of data-driven mass surveillance "is threatening to turn privacy into a relic of the 20th century," says the anonymous YouTube creator known as Ordinary Things.

This week, we're revisiting a talk in which Ordinary Things gives an enlightening account of the internet's strengths and weaknesses, warning that the fight for a free internet is a fight for our collective future.
  • Why humans should merge with AI | D. Scott Phoenix

    33:37|
    Deep tech entrepreneur D. Scott Phoenix spent years building AI — now, he believes we're on the cusp of a profound merger between humans and machines. Reframing the AI debate through the lens of evolutionary biology, he shifts the question from whether we should fear or embrace AI to whether we understand what's at stake if we get it wrong. Hear his provocative case for why we need to "eat the AI." After the talk, Sherrell interviews Baratunde Thurston, host of Life with Machines, on how to live well with technology.
  • Why AI isn't going to become conscious | Anil Seth

    19:37|
    We see consciousness in AI the same way we see faces in clouds, says neuroscientist Anil Seth. He explores the all-too-human tendency to project inner life onto machines that are brilliant mimics, not sentient beings, and gives a definitive answer to the urgent question: Will AI ever gain consciousness?
