Can planting more trees make allergies worse?
21 oct 2026, 7:00 · 11 min
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 oct 2026, 7:00 · 14 min
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, <a href="https://www.npr.org/people/1082526815/regina-g-barber"target="_blank" >Regina Barber</a> and <a href="https://www.sevenrasmussen.com/"target="_blank" >Seven Rasmussen</a> talk about the equation as it was created back in 1961 – and whether it still matters for astrobiologists today.

The terrifying physics of prehistoric sea monsters
16 oct 2026, 7:00 · 9 min
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 <a href="https://www.cell.com/current-biology/abstract/S0960-9822(26)01214-5?_returnURL=https%3A%2F%2Flinkinghub.elsevier.com%2Fretrieve%2Fpii%2FS0960982226012145%3Fshowall%3Dtrue"target="_blank" >Current Biology</a> details just how exactly they might have done that.

What's at stake if we can't regrow our forests
15 oct 2026, 7:00 · 13 min
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.

What Flock cameras really see – and how
14 oct 2026, 7:00 · 15 min
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 <a href="https://www.npr.org/2025/11/07/nx-s1-5587724/some-sanctuary-states-discover-feds-mining-local-license-plate-data"target="_blank" >use by federal agencies</a> expands, a handful of people have <a href="https://www.npr.org/2026/08/21/nx-s1-5939851/flock-cameras-police-block-surveillance-vandalize"target="_blank" >taken matters into their own hands</a>. 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, <a href="https://www.404media.co/author/joseph-cox/"target="_blank" >Joseph Cox</a>, 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.

One of the toughest parts of ADHD is left out of the diagnosis
9 oct 2026, 7:00 · 12 min
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.

What's missing from the lethal injection conversation
7 oct 2026, 7:00 · 14 min
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 carried out between 1890 and 2010 indicated that three out of every hundred executions were botched – and that lethal injection executions, which began in 1982, have a more frequent incidence of complications than any other method. All of this has re-raised the question of how humane lethal injections are as a form of execution. So, today on the show, we speak to anesthesiologist <a href="https://www.uwmedicine.org/bios/gail-van-norman"target="_blank" >Gail Van Norman</a>, a medical expert who testified about Christa’s case and many other lethal injection executions. She told us how she and other experts predicted much of how Christa's execution would unfold.

The genetic secret helping bats survive a deadly epidemic
5 oct 2026, 7:00 · 13 min
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 <a href="https://sites.google.com/view/giorgia-g-auteri/home?pli=1&authuser=0"target="_blank" >Giorgia Auteri</a> and her team noticed several genetic mutations in the survivors. These mutations could explain how natural selection has shifted the existing population – and inform conservation efforts in the future. Interested in more animal science?

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.

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 fuels — are making El Niños stronger.

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. That’s why today’s episode is a peek at a conversation Marisa had about self-worth on NPR’s self-help podcast Life Kit.

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 University of Cambridge and co-author of review, published in the journal Psychological Medicine. The review looked specifically at recreational reading — reading for fun — and found broad benefits for children, adolescents and older adults.

18 sept 2026, 7:00 · 14 min
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 advanced AI development. And Wednesday, OpenAI disclosed six more incidents of “unexpected or concerning model behavior” and debuted a new framework for reporting misalignments. So, given all these events, how worried should we be about the future of AI? And what safety measures are – or could be – set in place to safeguard humanity?

When batteries get a facelift, so does renewable energy
16 sept 2026, 7:00 · 13 min
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 technology with <a href="https://www.npr.org/people/1200794832/cooper-katz-mckim"target="_blank" >Cooper Katz McKim</a>, a producer on The Indicator from Planet Money.

Why you'll probably be misdiagnosed in your lifetime
15 sept 2026, 7:00 · 13 min
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 href="https://www.nationalacademies.org/projects/IOM-HCS-13-03"target="_blank" >a report</a> 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 editor and author of the book <a href="https://www.penguinrandomhouse.com/books/697282/the-elusive-body-by-alexandra-sifferlin/"target="_blank" >The Elusive Body: Patients, Doctors and the Diagnosis Crisis</a>.

Should race affect BMI guidelines? Doctors are split
14 sept 2026, 7:00 · 13 min
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 problems. So what’s the way forward? To find out, we talk to Katie Wu, a science writer at The Atlantic.

How scientists discovered that animals are doctors, too
11 sept 2026, 7:00 · 13 min
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 studying animals’ medical cabinets may be the most promising way to expand our own.

How hurricanes triggered lizard evolution
8 sept 2026, 7:00 · 11 min
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 fan and record how long they can hold on?

When is your brain actually 'adult'?
7 sept 2026, 7:00 · 13 min
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 <a href="https://www.nature.com/articles/s41467-025-65974-8"target="_blank" >the journal Nature</a> suggests that may not be the case. Neuroscientists found four distinct turning points in brain development across the human lifespan – and that the brain may be in its “adolescent” phase until about the age of 32.

The science of emotional regulation — and how to do it better
2 sept 2026, 7:00 · 12 min
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.

Football is here – and so is a new study on CTE
31 ago 2026, 7:00 · 15 min
The NFL season begins this week, but America’s favorite sport has been on our minds for other reasons recently. New <a href="https://doi.org/10.1136/bmj-2026-100418"target="_blank" >research released in the journal BMJ</a> 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 players who died from 2016 to 2021 – revealed that at least a quarter of those former players died with CTE, and the study’s lead author says the actual numbers are likely higher. What does that mean for players (and fans) of American football?

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. It should help scientists get a better understanding of the mysterious force known as dark energy – which will tell us about the fate of the universe.

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 experts warn that placed in the wrong hands, this technology could create the next pandemic. Interested in more AI-related research?

This year, the Department of Defense announced that they’d entered agreements with eight artificial intelligence companies. It follows decades of popular media exploring the idea of artificial intelligence in war – from the computer threatening global thermonuclear conflict in the movie WarGames to the Skynet neural net in Terminator. In 2026, when Anthropic’s Claude and OpenAI’s ChatGPT are just a click away, the concept of AI-supported war is suddenly much closer to reality. So what does it really mean for militaries to use AI?
