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 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.

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.

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.

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 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.

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 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.

The sound of fear: Why so many animals scream

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 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.

I never miss an episode, and frequently share with friends and family. They are informative, thoughtful, positive, and focused - always worth the time. I end each episode feeling more informed about our world, and it’s an important shot of positivity in my news-heavy podcast feed, without feeling like complete escapism.
