    AI is great at predicting text. Can it guide robots?

    It seems like artificial intelligence is everywhere in our virtual lives. It's in our search results and our phones. But what happens when AI moves out of the chat and into the real world? NPR science editor and correspondent Geoff Brumfiel took a trip to the Intelligence through Robotic Interaction at Scale Lab at Stanford University to see how scientists are using AI to power robots and the large hurtles that exist for them to perform even simple tasks.

  2. The physics of the Winter Olympics

    The physics of the Winter Olympics

    Watching a ski jumper fly through the air might get you wondering, “How do they do that?” The answer is – physics! That’s why this episode, we have two physicists – Amy Pope, a physicist from Clemson University and host Regina G. Barber – break down the science at play across some of the sports at the 2026 Winter Olympics. Because what’s a sport without a little friction, lift and conservation of energy? They also get into the new sport this year, ski mountaineering - or “skimo” as many call it - and the recent scandal involving the men’s ski jump suits.  Interested in more science behind Olympic sports? Check out our episodes on how extreme G-forces affect Olympic bobsledders, the physics of figure skating and the science behind Simone Biles' Olympic gold.  Also, we’d love to know what science questions have you stumped.

    These bacteria may be key to the fight against antibiotic resistance

    In 1928, a chance contaminant in Scottish physician Alexander Fleming’s lab experiment led to a discovery that would change the field of medicine forever: penicillin. Since then, penicillin and other antibiotics have saved millions of lives. With one problem: the growing threat of antibiotic resistance. Today on Short Wave, host Regina G. Barber talks to biophysicist Nathalie Balaban about the conundrum — and a discovery her lab has made in bacteria that could turn the tides. Check out our episodes on extreme bacteria in Yellowstone and the last universal common ancestor.  Interested in more science behind our medicines? Email us your question at shortwave@npr.org.

    Babies got beat: Why rhythm might be innate

    Rhythm is everywhere. Even if you don’t think you have it, it’s fundamental to humans’ biological systems. Our heartbeat is rhythmic. Speech is rhythmic. Even as babies, humans can track basic rhythm. Researchers wanted to find out if there were more layers to this: Could babies also track melody and more complicated rhythms? So they played Bach for a bunch of sleeping newborns and monitored the babies’ brains to see if they could predict the next note. What they found offers clues about whether melody and rhythm are hard-wired in the human brain or learned over time. We also get into what powers the eating habits of some snakes and chameleons, and insights into the role of sleep in problem-solving. Have a scientific question you want us to answer?

  5. How do extreme G-forces affect Olympic bobsledders?

    How do extreme G-forces affect Olympic bobsledders?

    Olympic sliding sports – bobsled, luge and skeleton – are known for their speed. Athletes chase medals down a track of ice at up to 80 or 90 mph. With this thrill comes the risk of “sled head.” Athletes use the term to explain the dizziness, nausea, exhaustion and even blackouts that can follow a brain-rattling run. Untreated, this can turn into concussions and subconcussions. But there’s still a lot more to learn about this condition. So today, host Emily Kwong speaks with two experts about the medical research into sled head – and how the sport would need to change to protect athletes’ brain health. Check out more of NPR’s Olympics coverage. Interested in more Olympic science? Email us your question at shortwave@npr.org.

    Autism: debunking Trump claims, and what scientists still don't know

    Autism has a long history of misinformation that continues to today. The Trump administration has perpetuated some of this misinformation in the last year. Among other things, officials have claimed certain groups of people don’t get the condition and that taking Tylenol while pregnant causes autism to later develop in children. Today, NPR Science Correspondent Jon Hamilton sets the record straight with host Emily Kwong on what scientists do and don’t know about autism.  If you liked this episode, check out our episodes on an Autism researcher’s take on Trump’s claims about Tylenol and a Fragile X treatment that may be on the horizon.

    Lessons and failures from the Challenger space shuttle explosion

    On Jan. 28, 1986, NASA’s 25th space shuttle mission, Challenger, left the launchpad in Cape Canaveral, Florida. Seventy-three seconds into flight, Challenger exploded over the Atlantic Ocean as millions of people watched. All seven people on board died. Now, forty years later, journalist Adam Higginbotham chronicles what went wrong. His book Challenger: A True Story of Heroism and Disaster on the Edge of Space pieces together stories from key officials, engineers and the families of those killed in the explosion – and details how its legacy still haunts spaceflight today.  Consider checking out our episode speaking to an astronaut while she’s in space.
