February 24, 2026 Could our trash become local fishes’ treasure?
Helicopters. Cargo containers. Old washing machines. For years, fishermen dumped this waste into the Gulf of Mexico. But they weren’t just trying to get rid of junk; they were trying to create artificial reefs that would help attract fish. For this month’s Nature Quest, WWNO coastal reporter Eva Tesfaye takes a (metaphorical) dive into the gulf to find out if Alabama’s ocean junkyard is an economic – and environmental – solution.

Want to learn more about artificial reefs? Check out WWNO's podcast Sea Change for more reporting from Eva and her colleagues.

This episode is part of Nature Quest, our monthly segment that brings you a question from a Short Waver who is noticing a change in the world around them.

February 23, 2026 The serious hunt for alien life
Bring up aliens and a lot of people will scoff. But not everyone is laughing. Around the turn of the century, 3.8 million people banded together in a real-time search for aliens — with screensavers. It was a big moment in a century-long concerted search for extraterrestrial intelligence. So far, alien life hasn't been found. But for scientists like astronomer James Davenport, that doesn't mean the hunt is worthless. It doesn't mean we should give up. No, according to Davenport, the search is only getting more exciting as new technology opens up a whole new landscape of possibilities. So, today, we're revisiting our episode on the evolving hunt for alien life.

February 21, 2026 The noise that isn't there
Almost 15% of adults suffer from a persistent, often intolerable sound... that is literally just in their heads. Why does the brain do this to us? We help one of our listeners get some answers.
This is the second episode of a five-part series called The Sound Barrier from our friends at Vox's Unexplainable podcast.Guests: Stéphane Maison, director of the tinnitus clinic at Mass Eye and Ear and Dan Polley, tinnitus researcher at Mass Eye and Ear

February 20, 2026 The truth about intermittent fasting
From TikTok and Instagram influencers to celebrities like Hugh Jackman and Kourtney Kardashian, intermittent fasting has gotten a lot of hype. The diet restricts what time you eat rather than what or how much you eat. The idea is that short periods of fasting cause your body to burn through stored fat reserves. But is that conventional wisdom true? And can it really contribute to weight loss? Regina G. Barber and Rachel Carlson tackle those questions — plus why some researchers are rethinking how to protect people's mental health when talking to chatbots and how ultra-endurance running changes the human body.

February 18, 2026 The neuroscience of cracking under pressure
The 2026 Winter Olympics are unfolding in Milan and Cortina, and we can’t look away: We’re watching athletes fly down mountains on skis and glide — sometimes slipping and falling — on the ice. Vikram Chib studies performance and how the brain responds to rewards at Johns Hopkins University. And he says rewards aren’t just for Olympians; they’re baked into basically everything humans do. But those rewards and the pressure that comes with them can come at a cost to people’s brains. And even Olympians are human. Sometimes, we crack. So, today, Vikram dives into the science behind choking under pressure.

February 17, 2026 Tea time... with an ape?
Picture this: You’re at a pretend tea party, but instead of sitting across from toddlers in tiaras, you’re clinking cups with Kanzi—an ape with the incredible ability to communicate with humans. NPR science correspondent Nate Rott talked to some scientists who did exactly that. But these scientists weren’t just having pretend tea parties with Kanzi for fun, they were trying to test the limits of his imagination – because humans’ ability to play out “pretend” scenarios in our heads and guess at the potential consequences of our actions is key to how we live our lives. And we might not be the only animals to do it!

For more of Nate’s reporting, plus videos of Kanzi, check out the full story on NPR here. Chris Krupenye’s study can be found here.

February 16, 2026 Could this vaccine trial mean a future without HIV?
Early last year, a hundred researchers, clinicians and other experts on HIV discussed the development of an innovative vaccine that could prevent the disease. But just as the meeting was about to wrap up, the mood darkened. A new executive order signed by President Trump on Inauguration day had frozen all foreign aid, pending a review. Soon, DOGE would begin its decimation of USAID — and with it, this vaccine trial. That is – until the South African researchers came up with a new plan.

February 13, 2026 Why do we kiss? It's an evolutionary conundrum
The evolutionary purpose of kissing has long eluded scientists. Smooching is risky, given things like pointy teeth, and inherently gross, given an estimated 80 million bacteria are transferred in a 10 second kiss. And yet, from polar bears to humans, albatrosses and prairie dogs, many animals kiss. So, what gives? Evolutionary biologist Matilda Brindle tells us the sordid details driving this behavior, what distinguishes different kinds of kissing and whether culture has anything to do with why people kiss.

February 11, 2026 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.

February 10, 2026 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.
