Can scientists reverse your age?
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 disea
How this year's record El Niño could hit your wallet
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. Inte
An ‘Ozempic baby boom’? The GLP-1 pregnancy plot twist
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.
Predicting elections is getting harder. What did the midterms teach us?
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 re
AI is changing mathematics -- but not how you think
Math has created some of humanity's oldest intellectual challenges. And AI is completely changing the game. This year AI solved one of math’s most difficult problems. Since then, OpenAI published hundreds of new math results. So is this the end for the people who’ve dedicated their careers to pushing forward math? We get into it with NPR science correspondent Geoff Brumfel, who weighs the risks an

Is your favorite crime show rooted in fake science?
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 Chri
MAHA’s midterm report card
It’s been just over two years since the rise of Make America Healthy Again, or MAHA. The movement united a coalition of moms, wellness influencers and voters across the political spectrum over concerns about chronic illness and childhood diseases. And when Robert F. Kennedy Jr. took over as Secretary of Health and Human Services, it seemed like MAHA would be front and center in Washington.But as w
You Can See Everything and the science of spotting liars
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 cou
The battle between matter and antimatter
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 s
The dormant viruses in all of us may help explain long COVID
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 a
Can planting more trees make allergies worse?
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?
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
What the world's leading researchers think about saunas
Saunas have gone from a Scandinavian tradition to a global wellness phenomenon. But how long should a person endure heat? Do saunas actually work? And if so, what are their benefits? NPR health reporter Will Stone goes as deep as the science will let him to explore the sauna hype waves and find out what happens to our bodies when we step in them.Interested in more about thermal physiology?

The terrifying physics of prehistoric sea monsters
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 paleontologic
What's at stake if we can't regrow our forests
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
What Flock cameras really see – and how
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
The sound of fear: Why so many animals scream
It's Halloween season — and what better way to celebrate October 13th than to explore the haunting sound of fear? That's exactly what we do in this episode, where host Regina G. Barber and NPR science correspondent Nate Rott dive into the science behind the sound of fear. Along the way, they find out what marmot shrieks, baby cries and horror movie soundtracks have in common — and what all of this
One of the toughest parts of ADHD is left out of the diagnosis
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
What's missing from the lethal injection conversation
You might have seen the news that Christa Pike, a convicted murderer in Tennessee, did not die from the injections given to her as part of her death penalty sentence last week. After her failed execution, she was hospitalized, where she continues to receive critical medical care, according to her attorneys. Her survival is singular, but her mishandled execution is not. A review of executions carri
Science-backed guidance for healthy screen time
We’re all aware – and wary – of doomscrolling. Lots of screen time can be bad for us. But what if that’s not always the case? We spoke with the author of a study that found a positive relationship between screen time and brain development in young people. This episode, we sort through what to actually worry about when it comes to screen time – and what guidelines already exist that can empower you
The genetic secret helping bats survive a deadly epidemic
We’re easing you into Halloween season with an episode about bats. There’s a silent serial killer decimating little brown bats as they hibernate. White nose syndrome has driven populations across the U.S. to almost the brink of extinction over the last decade. But recently, conservation biologist Giorgia Auteri and her team noticed several genetic mutations in the survivors. These mutations could
Eating alone may be secretly spiking your blood sugar
Being more social has a ton of benefits: lower stress, decreased inflammation – even living a longer life! Recently, some scientists have added lowering your blood sugar to the list. To figure it out, researchers had people break bread both in duos and alone. And they think the results could tell us something about the roots of our social nature. Consider it another reason to prioritize our social
How much of Earth's life is still undiscovered?
If you, like us, clicked on the cute cat photos posted everywhere recently, announcing the discovery of the first new cat species in more than a century, you might have wondered how rare it is to find a new species. Turns out, it’s not! We live in an era of “unprecedented” discovery, says John Wiens, a professor of ecology and evolutionary biology at the University of Arizona. And scientists say w
What social media gets wrong about inflammation
Inflammation is all over our feeds. Influencers claim it’s the reason you're bloated or fatigued, the source of digestive problems and the cause of more serious illnesses like Alzheimer's or cardiovascular disease. But how much of that is scientifically backed, and how viable are the solutions you see on social media? Short Wave talks to immunologist Shruti Naik to separate the health from the hyp
A fall mystery: why do only certain leaves turn red?
Leaves turn yellow in the fall because Chlorophyll breaks down, revealing the yellow pigment that was there all along. But why red? Red is a different story altogether. Leaves have to make a new pigment to turn red. Why would a dying leaf go an extra mile to do that? Scientists don’t really know. NPR science correspondent Nell Greenfieldboyce reports on the leading hypotheses out there.Read more o
'Super' El Niño is coming. What should you expect?
The world is bracing for the worst effects of a Super El Niño. Or a Godzilla El Niño. But what does that really even mean?For millennia El Niño has shaped weather across the globe, fueling flooding in parts of the U.S., droughts and wildfires in Australia and Indonesia, and disrupting fisheries across the Pacific.Scientists have long wondered if human activities — chiefly the burning of fossil fue
Vaccinated or not, we’re on the brink of a measles epidemic
Measles is making a comeback. Ongoing outbreaks in Pennsylvania, South Carolina, Texas, and Utah have documented hundreds of cases, mostly among unvaccinated people. And while local and federal politicians debate the definitions and impact of those measles-associated deaths, health experts worry that we’re overlooking the real problem: the threat of a full-scale epidemic. Today, we talk to one of
The science of self-worth (and how to boost yours)
Your self-worth today can be affected by your memories. But you have power over those memories – when you re-experience them. By doing that, you can reshape your self-esteem for the better and change your perspective. That idea and the broader science of self-worth are at the heart of Marisa Franco’s new book Worth. It’s so intriguing to us, we couldn’t pass up the chance to share it with you. Tha
Why we should all be 'bookmaxxing'
Remember your mom, dad and teachers telling you to read because it’s good for you? Well, a compilation of the latest research shows they were right. “Reading is one of the simplest and most accessible activities for actually supporting cognitive performance, brain health, mental health, but also overall wellbeing throughout our lives,” said Christelle Langley, a cognitive neuroscientist at the Uni
The latest on AI panic — and whether it's justified
AI is in the news again – for its potential to end civilization. A researcher at Anthropic resigned very publicly last week, citing concerns about the accelerating capabilities of AI and what he called “irresponsible” behavior from major AI companies Anthropic and OpenAI. Following his resignation, the leaders of both companies called for an internationally cooperative, industry-wide slowdown on a
When batteries get a facelift, so does renewable energy
For years, renewable energy companies have faced a problem: How to store the mass amounts of energy they produce for later use. Batteries may be just the solution. In California, there's now enough grid-scale battery storage to power millions of homes for a few hours. Battery power is often the second largest source of energy on a given day in the state. So, we're revisiting the fast-growing techn
Why you'll probably be misdiagnosed in your lifetime
Nearly every person will experience at least one diagnostic error in their lifetime. That means either a delayed diagnosis, a wrong diagnosis – or no diagnosis at all. That’s according to a report by the National Academies of Sciences, Engineering and Medicine from 2015 on diagnostic error. Today on the show we talk to a physician who was personally affected by the crisis, and New York Times edito
Should race affect BMI guidelines? Doctors are split
BMI is a quick, cheap way for doctors to estimate body fat and screen for conditions like heart disease and diabetes. But medicine has long known that BMI is problematic and unnuanced. By using it, groups of people have fallen through the cracks and conditions have been caught late. So, some doctors want to add nuance – to consider race when using BMI. But using race in medicine comes with its own
How scientists discovered that animals are doctors, too
When people are sick, we seek out medications and treatments to help heal. For a long time, scientists thought that was a uniquely human ability. But it turns out, many other animals do a version of it too! And since the late 1980s, western researchers have been trying to get a peek behind the curtain. And aside from just cataloguing all the cool examples just to know, there’s a real hope that stu
Lindsay Clancy and postpartum psychosis
The trial around Lindsay Clancy may be over for now, but it still leaves us with questions. On today’s episode, we talk to psychiatrists and patients to answer them: What is postpartum psychosis, exactly? Why don’t we know more about it? And what can you do if you are worried about a postpartum loved one?Interested in more stories on mental health? Email us your question at shortwave@npr.org.Suppo
How hurricanes triggered lizard evolution
Hurricane season is upon us and it turns out that these powerful storms can quickly affect the biology of animals. After hurricanes Irma and Maria hit the islands that make up Turks and Caicos about a decade ago, the silver key anole adapted. They now have a shorter fourth toe on their hind legs! That could help them cling to objects better. But how do you know unless you put lizards in front of a
When is your brain actually 'adult'?
Summer is winding down and school is back. And all of that has us thinking about this idea that something happens in the human brain when we turn 25. Suddenly, we can rent a car without fees. Make rational decisions. We may even regret some of our past… indiscretions. All because we’re developed…right? Well, a paper in the journal Nature suggests that may not be the case. Neuroscientists found fou
A new investigation shows heat is even deadlier than we thought
Hot weather isn’t just an inconvenience. It’s killing thousands more Americans than show up in official records. That’s the finding from a new NPR investigation, in partnership with Boston University. And the way they came up with that new, better estimate of the true toll of heat is, of course, with science. This episode, we’ll bring you all the details – and chat about why getting good estimates
The science of emotional regulation — and how to do it better
Do you ever feel like your emotions control you instead of you controlling them? Maybe you lash out at someone after a long day at work or indulge to avoid a stressful situation. It’s called emotional dysregulation and don’t worry – we all experience it at some point. Luckily, there’s a better way of dealing with our feelings: building emotional intelligence. That may seem daunting, but Short Wave
What can seashells teach us about the health of our oceans?
Seashells: They're beautiful remnants to carry home from the beach—and so much more! According to environmental journalist Cynthia Barnett, seashells record history more accurately than the humans who first wrote it down.

Football is here – and so is a new study on CTE
The NFL season begins this week, but America’s favorite sport has been on our minds for other reasons recently. New research released in the journal BMJ reveals that 1 in 4 former NFL players in this sample had CTE, a neurodegenerative brain disease caused by repetitive head injuries. Past studies already showed that football players are at high risk for CTE, but this study – which assessed ex-NFL
NASA's newest telescope has a top secret past
The new Nancy Grace Roman space telescope is slated to launch this weekend. It was originally built for the National Reconnaissance Office as a spy satellite, but was never launched. Instead, NRO gave it to NASA about 15 years ago. After some major modifications, it’s set to begin its five-year mission peering at new supernovas, distant galaxies and planets orbiting stars outside our solar system.
How your metabolism could alter your mental health
In 2009, medical student Shebani Sethi watched a patient in a weight loss program make a remarkable recovery. The dietary intervention she underwent alleviated her schizophrenia symptoms, something the woman had tried – and failed – to treat with medication for years. That experience sent Shebani down a medical path that would lead her to treating mental health in a radically different way. Today
AI-made viruses could be the future of medicine
The era of AI-generated viruses is here. Some scientists are using AI to design viruses that can attack bacteria. The hope is that these tailor-made viruses can fight drug-resistant bacterial infections in people. And longer-term, Brian Hie, the Stanford researcher spearheading this project, hopes that AI can help create more complicated biological systems to treat formidable diseases. But some ex
How much has the U.S.’s wildlife changed since Lewis and Clark?
Ever wish you could have been part of the Lewis and Clark expedition? Us too. The Corps of Discovery came across scores of plants and animals that were new to Western science: Grizzly bears, ponderosa pines, a “barking squirrel” that William Clark would later call the prairie dog.

Those levels affect more than just sex. They also affect metabolism, bone health, musc
A survivor's view from inside a tornado
What’s the dumbest thing Perry Samson says he’s ever done? Getting caught inside a tornado. But when you’re an atmospheric scientist who studies supercell thunderstorms—with a special interest in the ones that cause tornadoes—that sort of thing is a bit of an occupational hazard. Lucky for Perry, he also made a split-second decision while in the tornado that may be the smartest thing he’s ever do
Could future wars be fought by AI?
This year, the Department of Defense announced that they’d entered agreements with eight artificial intelligence companies.

But Jon is retiring, so today on the show he joins us to share the most memorable
What's this super-aging butterfly’s longevity secret?
What if there were a great ape species that could live over 1,000 years? That’s basically Heliconius in the butterfly world. The insects live around 25 times longer than their butterfly cousins, and scientists think they have one clue as to why: pollen. But as Katie Wu, a science writer at The Atlantic, explains, that’s not the whole story. She and host Nate Rott also talk about how bats sip from
How should we decide who, or what, is conscious?
In the age of AI, what differentiates humans from robots? What makes humans … human? To find answers, many people are studying consciousness: our capacity for experience. But doctors and researchers still have a long way to go when it comes to finding new ways to detect consciousness in humans — much less computer software. That gets especially tricky when people are unable to use their words or b
Plot twist: We're probably way undercounting insects on Earth
Maybe you’ve wondered about it late at night as a mosquito buzzes in your ear. Or when you kick over a rock and watch dozens of little critters crawl away: How many types of insects are there in the world? Scientists have been interested in answering this question for years. A new study — based on a census of tiny and, frankly terrifying, parasitoid wasps — suggests there’s way more than previousl
NASA's race against time to rescue a falling satellite
A valuable NASA satellite observatory is falling to Earth faster than scientists expected. It’s called the Neil Gehrels Swift Observatory, or “Swift” for short, and it can respond to celestial events much faster than its sky-gazing counterparts. To save Swift and test out a first-of-its-kind technology, NASA partnered with an Arizona-based startup to launch a refrigerator-sized robot, aptly named

Is setting your trash on fire a good idea?
The U.S. generates 292 million tons of trash each year – and that trash has to go somewhere. Sometimes, that’s to an incinerator, where it’s burned and turned into electricity. Proponents of incineration applaud the ability to generate energy from waste and divert garbage from landfills. Opponents worry about the potential health risks, especially to minoritized communities. Today on the show, we
Ticks are a growing problem, no matter where you live
