  Can scientists reverse your age? 11.11.2026 14m

  Reversing aging may sound like science fiction, but scientists have already found a way to do it—at least, theoretically. Based on a 2012 Nobel-prize winning discovery, researchers are testing whether they can revert diseased cells in the eye back to young and healthy ones. They gave people a drug this year. If it works, it’ll open the door to curing and possibly preventing other age-related diseases. And that led producer Berly McCoy to wonder: Could all this research eventually extend our human lifespans? If you like this episode, check out our episodes on zombie cells, why our hair turns gray and why we die.Interested in more science on aging?

  How this year's record El Niño could hit your wallet 10.11.2026 9m

  Peru’s anchovy industry, the largest single-species fishery in the world, is being rocked by the ongoing El Niño . It’s not the first time the fishery has been impacted by the natural weather phenomenon — El Niño gets its name from Peruvian fishermen. And it’s a stark reminder of the reverberating economic consequences of El Niño events, which can cost the global economy trillions of dollars. Interested in more news and weather-related science?

  An ‘Ozempic baby boom’? The GLP-1 pregnancy plot twist 09.11.2026 12m

  The explosion of GLP-1 drugs has created a gray zone for pregnancy. That recently prompted the American College of Obstetricians and Gynecologists to issue its first ever guidance on the topic. In a twist, the drugs may boost fertility for some, leading to more pregnancies – a phenomenon known on social media as “Ozempic babies”. But doctors caution against using the drugs during pregnancy itself. In fact, the more we looked into this story, the more twists and nuances we found. So, we brought Dr. Amy Valent of Oregon Health and Science University onto the show to break down the latest on what’s known about how these drugs affect fertility and pregnancy. Interested in more health news?

  Predicting elections is getting harder. What did the midterms teach us? 05.11.2026 12m

  Famously, polls got the 2016 election wrong. And they’d been off for multiple elections since. So, Monday night, political scientist Jack Rametta nervously refreshed his Senate forecasting model for the final time. Would it be right this time? Or would it yet again cast doubt on whether modeling, statistics and forecasting can still help us understand what motivates people to vote? Now that the results are in, so is Jack – to tell us how he did, and what his and other researchers’ predictions tell us about the evolving science of polling and forecasting.Interested in more science behind the news?

  Is your favorite crime show rooted in fake science? 30.10.2026 14m

  If you’ve ever seen a crime show, you probably know how the plot unfolds: A victim is found, an investigation ensues and police conduct a high-stakes search for the culprit. Detectives and crime lab techs collect hair, examine bullet casings and photograph bloodstains. But just how reliable are these clues – and does science back them up? Well, today on the show, with the help of legal expert Chris Fabricant, we’re diving into which of these forensic techniques are junk “science”, which we should be more cautious about – and why all of them haunt the legal system.Interested in more crime and pop science?

  You Can See Everything and the science of spotting liars 27.10.2026 13m

  It feels like everyone we know is talking about the new documentary You Can See Everything. It tracks the effort of comedian and documentarian Nathan Fielder to suss out how deceptive Elizabeth Holmes, disgraced founder of the company Theranos, is. And after watching the film, we all left the theater wondering -- what could we see? How possible is it to ever really spot someone lying? So we of course called up an expert in deception and counter-deception research, Maria Hartwig, a professor of psychology at CUNY, the City University of New York. For more on sussing out a liar, check out our episode about what's wrong with the polygraph.

  The battle between matter and antimatter 26.10.2026 11m

  At the beginning of our universe, in addition to matter, there was also an equal amount of antimatter, matter's opposite. But today, there's lots more matter than antimatter. So how did that happen? Well, the answer might have to do with neutrinos, a very mysterious, elusive particle. They're incredibly difficult to catch and study because they don't really interact with anything. But a group of scientists is now betting that one specific, hypothetical type of neutrino might have played a very important role in getting matter to win the war against antimatter. Today, we go galaxy brain and delight in getting to spend a little time pondering this hypothetical, long ignored particle.Support public media with NPR+ and enjoy perks for over 25 podcasts like this one.

  The dormant viruses in all of us may help explain long COVID 23.10.2026 14m

  Virtually every human on Earth has a slew of different types of dormant viruses in our bodies. They are remnants of past infections and are—generally—harmless. Unless they wake up, which can be triggered by extreme stress or something that severely compromises the immune system. But now, through a unique study on the immune systems of astronauts, scientists are considering broadening their ideas about what can wake up our dormant viruses…and learning what all this has to do with long COVID. If you liked this episode, check out our episodes on a universal flu vaccine and what scientists got wrong about covid.Support public media with NPR+ and enjoy perks for over 25 podcasts like this one.

  Can planting more trees make allergies worse? 21.10.2026 11m

  Trees provide shade and clean air in congested cities, so planting more of them seems like a straightforward solution. But trees also produce a natural pollutant— pollen. In this episode, producer Juan Diego Ramirez reports on the link between growing urban canopies and allergy exposure, and what you can do to protect yourself.Interested in more health stories?

  What are the odds we're not alone in the universe? 20.10.2026 14m

  There are hundreds of billions of stars in the galaxy we live in. Many of them have their own exoplanets. So why haven’t we found proof of alien life yet? And what’s the probability of us contacting or being contacted anyway? That’s exactly what a famous math formula called the Drake Equation tries to answer. It takes into account a whole variety of factors, including the rate at which stars like the Sun are born, how many of those stars have planets, how many of those planets are hospitable to life and the likelihood of intelligent life on that habitable planet communicating with us. Today on the show, Regina Barber and Seven Rasmussen talk about the equation as it was created back in 1961 – and whether it still matters for astrobiologists today.Interested in more episodes on space or math?

  The terrifying physics of prehistoric sea monsters 16.10.2026 9m

  While dinosaurs roamed the earth, giant monsters roamed the sea. Mosasaurs were like the deadly T-rexes of the ocean: They grew up to the size of a bus and chased down their smaller prey. A recent study in the journal Current Biology details just how exactly they might have done that. And the answer is fast – way faster than humans can swim – and sneakily.Interested in more animal or paleontological news?

  What's at stake if we can't regrow our forests 15.10.2026 13m

  In 2022, parachutist Luigi Cani dropped 100 million seeds over the Amazon rainforest while skydiving. He did it to raise awareness about deforestation and help regrow the forest. But there has been little scientific follow up to see whether it worked. So, today, we talk to restoration ecologist Pedro Brancalion about the surprising complexity involved in regrowing a forest, and when dropping seeds from the sky – by people or by drones – could work.If you liked this episode, check out our others on building microforests in cities and scientists’ creative idea to save a keystone tree species that grows very slowly.Interested in more tree science?

  What Flock cameras really see – and how 14.10.2026 15m

  Police departments across the U.S. are installing Flock cameras, saying the surveillance devices help deter theft and solve crimes, like helping find stolen property and missing people. But as the technology and its use by federal agencies expands, a handful of people have taken matters into their own hands. A hacker collective ripped down a Flock camera and made a copy of the software inside for investigative journalists at 404 Media and Wired. We talk to one of those journalists, Joseph Cox, about what he and his colleagues found, how the data is being used, why some residents are pushing back against the cameras and the future of the technology.Interested in more science and technology news?

  One of the toughest parts of ADHD is left out of the diagnosis 09.10.2026 12m

  ADHD diagnoses are on the rise in the United States, but what if professionals are missing a key part of the disorder? In the 1970s, some clinicians recognized a lot of their ADHD patients had trouble with emotional regulation. But because it was easier to measure behavior rather than emotions, the criteria eventually fell off the radar. Today in the U.S., emotional dysregulation is not a part of the ADHD diagnostic criteria in the Diagnostic and Statistical Manual of Mental Disorders (DSM). Dr. Sasha Hamdani thinks that needs to change. In today’s episode, she talks about her book Too Sensitive, and explains what is going on in the brains of people with Rejection Sensitive Dysphoria. Interested in more mental health science?
