PBS News Hour - Science - Despite setback, researchers uncover new findings at Antarctica’s Thwaites Glacier

As Trump pulls back from regulations on climate change, many scientists remain worried about the warming of the oceans, melting glaciers and sea level rise. Science correspondent Miles O'Brien has been reporting from Antarctica on a mission to understand what's happening there. In his last report from the Thwaites Glacier, he looks at other key research projects that have been part of that trip. PBS News is supported by - https://www.pbs.org/newshour/about/funders.

Short Wave - 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. (encore)

Short Wave - 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.

Short Wave - 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.

PBS News Hour - Science - How sports betting is changing our brains and behavior

Americans are expected to place a record-breaking $1.7 billion in legal bets on the Super Bowl. With a potential casino inside every phone and computer, a rising chorus of experts who study problem gambling and addiction are ringing the alarm. Horizons moderator William Brangham explores this tidal shift in American culture with journalist Danny Funt and addiction psychiatrist Dr. Timothy Fong.

CrowdScience - Do multiple choice questions make us biased?

CrowdScience listener Griffith in Ghana, isn’t JUST a CrowdScience listener. He’s also a listener to our sister show on the World Service, Unexpected Elements. But he’s noticed something funny.

In the weekly Unexpected Elements multiple-choice quiz, the answer is almost NEVER ‘a’. It’s nearly always ‘b’, or ‘c’. Why is this? When we set the quiz, why are we so reluctant to choose option ‘a’?

His question leads presenter Alex Lathbridge on a journey into the murky depths of our brain, where he discovers the cognitive biases which so often trip us up in games of chance, or probability. Your brain might be a marvellous machine when it comes to figuring out how to understand the world, but sometimes, in the name of efficiency, it takes clever little short-cuts to the answer.

This pragmatic approach to problem solving helps us manage an incredibly complicated world. But occasionally, especially when it comes to mathematics, chance, and probability, it leads us in the wrong direction. With the help of mathematician Kit Yates from the University of Bath in the UK, and some rather stale sweets, Alex will be finding out how to win at games of chance.

Alex also explores the world of gaming, and gambling. Games of chance in which our intuition sometimes lets us down, and makes us choose unwisely. Rachel Croson, Professor of Economics at the University of Minnesota, USA, talks us through how the human brain can work against us.

But can knowledge of those human pitfalls help us to win? Alex hears from Maria Konnikova, who turned her research on the psychology of poker into a successful gambling career. Can we really use maths to beat our brains, and learn how to win more often?

Unexpected Elements - Let the games begin

The Winter Olympics has the Unexpected Elements team looking into some of the incredible science behind the sports. First up, the tale of India’s lone luge pilot: how did using old train tracks as sled runners give him a competitive edge? Then, we look at the physics behind a cheating scandal that has rocked the ski jumping world. Scientific studies tell us exactly how much difference changing a single stitch in a costume can make.

Did you know there are different types of ice? Professor Christoph Salzmann has discovered three of them, and tells us what makes them unique. Plus dinosaurs, disease, and whether we laugh with an accent. All on this week’s Unexpected Elements.

Presenter: Marnie Chesterton, with Chhavi Sachdev and Tristan Ahtone Producers: Margaret Sessa-Hawkins, with Lucy Davies, Imy Harper and Tim Dodd

Short Wave - 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.

PBS News Hour - Science - Researchers face serious obstacles to measuring Antarctica’s fastest-melting glacier

If you've been following Miles O'Brien's reports from Antarctica, you know he's with an international group of researchers trying to measure what's happening to the rapidly melting Thwaites Glacier. Their work has been trying to capture information in ways that have never been done before. O'Brien has an update on how all that turned out, for our Tipping Point series.

Short Wave - 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.
