Ever wondered why your dog’s back-and-forth shaking is so effective at getting you soaked? Or how bugs, birds, and lizards can run across water—but we can’t? Or how about why cockroaches are so darn good at navigating in the dark? Those are just a few of the day-to-day mysteries answered in the new book How to Walk on Water and Climb Up Walls: Anim…

Moon Rocks Collected In 1972 Reveal New Secrets It’s hard to imagine, but the moon we all know and love hasn’t always been in the sky. Like all of us, the moon has an age. Until recently, our lunar neighbor has been estimated to be about 4 billion years old. But new research on lunar crystals from the Apollo 17 mission has helped researchers pinpoi…

Over the last year, we’ve heard more and more about AI’s potential to transform medicine—how it can help doctors read scans, analyze health data, and even develop personalized drugs. But the AI boom has set off alarm bells for some healthcare providers. Guest host Flora Lichtman talks with two scientists who wondered whether these models were perpe…

Scientists observing the exoplanet WASP-107b with the James Webb Space Telescope say that the planet has clouds of sand high in its atmosphere. The scientists detected water vapor, sulfur dioxide, and silicate sand clouds in the atmosphere of the planet, which is about the mass of Neptune but the size of Jupiter—stats that caused astronomers to des…

Perhaps you’ve marveled at the engineering feats of the Golden Gate Bridge or the Hoover Dam. Maybe you’ve thought about how many train tracks run in and out of Grand Central Station. But it’s sometimes easy to forget just how important well-functioning infrastructure is in our day-to-day lives. Flip a light switch, and the light comes on. Wash a l…

Over 99% of a human cell is made up of just five elements: carbon, hydrogen, oxygen, nitrogen, and phosphorus. That same elemental mix exists, with minor variations, in every other living thing on Earth. In his new book, Elemental: How Five Elements Changed Earth’s Past and Will Shape Our Future, author Stephen Porder writes about how these buildin…
