    Well informed: how to get strong

    Conventional wisdom has it that you need to move your body regularly to stay fit. But these days scientists argue that you should probably trade in the treadmill for some dumbbells. Strength training is having a moment. In this episode, part of our “Well informed” series on wellness trends, we take an evidence-based look at three popular routes to maximising your strength: weightlifting, eating protein, and taking creatine supplements. The world of fitness is filled with powders and supplements that claim bold things, but what’s the real secret to becoming—and staying—strong? Host: Alok Jha, The Economist’s science and technology editor. Contributors: The Economist’s Tim Cross, Richard Kreider of Texas A&M University.

  2. JUNO: the hunt for the universe’s most elusive particles

    JUNO: the hunt for the universe’s most elusive particles

    Neutrinos are elementary particles that are extremely light and rarely interact with anything else. Mostly, they pass invisibly through the universe—hundreds of trillions of neutrinos will have passed through your body as you read this. For physicists, though, these ghostly particles present a big problem. The prevailing theory of particle physics, the Standard Model, predicts that neutrinos should have no mass—but this is not what physicists observe in the real world. Now, scientists at JUNO, an enormous new lab in China, have started to hunt for the elusive particles and, in doing so, they hope to solve this giant conundrum in fundamental physics. Host: Alok Jha, The Economist’s science and technology editor, with Emilie Steinmark, The Economist’s science correspondent. Contributors: Juan Pedro Ochoa-Ricoux of the University of California, Irvine; Wang Yifang and Yuekun Heng of the Chinese Academy of Sciences.

    No going back: climate tipping-points

    What if the Amazon rainforest shrank to the point where it could no longer sustain itself? Or the ocean currents around Europe collapsed, freezing the continent? What if all this happened in just a few decades? Climate change is often perceived to be a disaster in slow motion, but a growing number of scientists worry about climate “tipping points”—thresholds in the climate system that, once crossed, could lead to sudden, catastrophic, irreversible changes. How can scientists predict how close such dramatic changes might be and how much devastation they might cause? Host: Rachel Dobbs, The Economist’s environment editor. Contributors: Jonathan Nash of Oregon State University; Jack Williams of the University of Wisconsin–Madison; James Veale and Liz Thomas of the British Antarctic Survey.

    Devi Sridhar: living a long life isn't a solo endeavour

    How long you live may be shaped less by your gym routine or diet plan than by the systems that surround you, from clean air and water to safe streets and accessible healthcare. In this episode, Devi Sridhar, a professor of global public health at the University of Edinburgh, argues that governments—not individuals—hold the greatest power to extend lives. She explains what people can learn from long-lived communities in Japan and Europe, how to curb the harms of ultra-processed food, the role of GLP-1 weight-loss drugs, and how tackling inequality could help everyone live healthier into old age. Alok Jha, The Economist’s science and technology editor, speaks with Devi Sridhar, the author of “How Not to Die (Too Soon)”. Transcripts of our podcasts are available via economist.com/podcasts.

    Arms race: how good is Chinese AI?

    More than six months on from DeepSeek’s breakthrough, how much has China’s AI ecosystem evolved? As it turns out, quite a bit. In an extended interview with Alex Hern, The Economist’s AI writer, we examine the major players in China, their models and how Chinese AI stacks up against its Western rivals. Now that the White House has lifted restrictions on the export of high-end chips to China, how might the battle for AI supremacy unfold?

    The bomb (part 4): the stewards of America’s nuclear weapons

    How is a new era of great-power rivalry affecting America’s nuclear security enterprise? Three national laboratories are tasked with keeping America’s warheads safe, modernising them and even building new ones. And, unlike during the cold war, they have to do it all without conducting explosive tests. With political tensions on the rise around the world, the labs’ mission has become more important than ever. This week, we investigate how the directors of the three labs are meeting this new moment. “The Bomb” is a four-part series which traces the scientific story of nuclear weapons. We go behind the scenes at America's nuclear-weapons laboratories to find out how the country is pushing the frontiers of extreme physics, materials science and computing to modernise its stockpile. In episode four, we ask the people who manage the bombs what it’s like to be responsible for such terrible and devastating weapons. Host: Alok Jha, The Economist’s science and technology editor. Contributors: Thom Mason of the Los Alamos National Laboratory; Kim Budil of the Lawrence Livermore National Laboratory; and Laura McGill of Sandia National Laboratories.

    The bomb (part 3): how to build a modern nuclear weapon

    How are nuclear weapons maintained and modernised in the 21st century? America stopped explosively testing its warheads and bombs in 1992. Now the country relies on sophisticated computer simulations and energetic lasers to understand how these devices work and to keep them safe as they age. For the first time ever, America’s nuclear scientists are also having to design a brand new warhead using simulations alone. This four-part series traces the scientific story of nuclear weapons. We go behind the scenes at America's nuclear-weapons laboratories to find out how the country is pushing the frontiers of extreme physics, materials science and computing to modernise its stockpile. In episode three, we explore the vast scientific infrastructure in place to maintain, upgrade and build a new generation of bombs, all without setting off any devices. Host: Alok Jha, The Economist’s science and technology editor. Contributors: Mark Herrmann, Brad Wallin, Rob Neely and Kim Budil of the Lawrence Livermore National Laboratory; and Laura McGill of Sandia National Laboratories.

    The bomb (part 2): the atomic town

    How did the atom bombs of the Manhattan Project become the nuclear stockpile of today? At the heart of America’s nuclear security enterprise lies a town: Los Alamos. It is where the first nuclear bomb was created. Today its national lab is tasked with designing and building America’s first new warhead in decades. This four-part series traces the scientific story of nuclear weapons. We go behind the scenes at America's nuclear-weapons laboratories to find out how the country is pushing the frontiers of extreme physics, materials science and computing to modernise its stockpile. In episode two, we look at the town that built the first nuclear bomb—and how the race to build better, more powerful nuclear weapons ended up building the town. Host: Alok Jha, The Economist’s science and technology editor. Contributors: Kristen Hollis and Todd Nickols of the Los Alamos Historical Society; Nic Lewis and Thom Mason of the Los Alamos National Laboratory; Ellen Bradbury Reid and Jim Bradbury, who grew up in Los Alamos.
