Today, we're going full nerd to talk about a new board game — Catan: New Energies. The game's goal is simple: Build and develop a modern-day island without catastrophically polluting it. Although the concept mirrors the effects of climate change, those words don't actually appear in the game. NPR correspondent Nate Rott talks to Emily about the thinking behind the new game and how the developers hope it can start conversations arou...

Pediatrician Mona Hanna-Attisha recognized a public health crisis in the making and gathered data proving the negative health impact on Flint's young children. In doing so, she and community organizers in Flint sparked a national conversation ...

NPR's Tom Dreisbach is back in the host chair for a day. This time, he reports on a story very close to home: The years-long battle his parents have been locked in with the local wild beaver population. Each night, the beavers would dam the culverts along the Dreisbachs' property, threatening to make their home inaccessible. Each morning, Tom's parents deconstructed those dams — until the annual winter freeze hit and left them all ...

Roughly 196 million tons of fish were harvested in 2020, according to the Food and Agriculture Organization of the United Nations. The organization also notes that the number of overfished stocks worldwide has tripled in the last century. All of this overfishing has led to the decline of entire species, like Atlantic cod.

When the dinosaurs walked the Earth, massive marine reptiles swam. Among them, a species of Ichthyosaur that measured over 80 feet long. Today, we look into how a chance discovery by a father-daughter duo of fossil hunters furthered paleontologist's understanding of the "giant fish lizard of the Severn." Currently, it is the largest marine reptile known to scientists.

500 million years ago, the world was a very different place. During this period of time, known as the Cambrian period, basically all life was in the water. The ocean was brimming with animals that looked pretty different from the ones we recognize today — including a group of predatory worms with a throat covered in teeth and spines.
Researchers thought these tiny terrors died out at the end of the Cambrian period. But a ...

We've all been there: You sit down for one episode of a reality TV show, and six hours later you're sitting guiltily on the couch, blinking the screen-induced crust off your eyeballs.
Okay. Maybe you haven't been there like our team has. But it's likely you have at least one guilty pleasure, whether it's playing video games, reading romance novels or getting swept into obscure corners of TikTok. It turns out that experien...

Wednesday the Environmental Protection Agency announced new drinking water standards to limit people's exposure to some PFAS chemicals. For decades, PFAS have been used to waterproof and stain-proof a variety of consumer products. These "forever chemicals" in a host of products — everything from raincoats and the Teflon of nonstick pans to makeup to furniture and firefighting foam. Because PFAS take a very long time to break down, ...

It's National Siblings Day! To mark the occasion, guest host Selena Simmons-Duffin is exploring a detail very personal to her: How the number of older brothers a person has can influence their sexuality. Scientific research on sexuality has a dark history, with long-lasting harmful effects on queer communities. Much of the early research has also been debunked over time. But not this "fraternal birth order effect." The fact that a ...

It's baseball season! And when we here at Short Wave think of baseball, we naturally think of physics. To get the inside scoop on the physics of baseball, like how to hit a home run, we talk to Frederic Bertley, CEO and President of the Center of Science and Industry, a science museum in Columbus, Ohio. He also talks to host Regina G. Barber about how climate change is affecting the game.

Tiny, black-capped chickadees have big memories. They stash food in hundreds to thousands of locations in the wild – and then come back to these stashes when other food sources are low. Now, researchers at Columbia University's Zuckerman Institute think neural activity that works like a barcode may be to thank for this impressive feat — and that it might be a clue for how memories work across species.

On April 8, the moon will slip in front of the sun, blocking its light and creating an eerie twilight in the middle of the day. Stars will come out, the air will get cold, colors will dance around the horizon. It's a full-body experience born from the total solar eclipse that will be visible from North America. Today on the show, Regina G. Barber talks to NPR science correspondent Nell Greenfieldboyce about why some people say this...

Historic numbers of animals across the globe have become endangered or pushed to extinction. But some of these species sit in limbo — not definitively extinct yet missing from the scientific record. Rediscovering a "lost" species is not easy. It can require trips to remote areas and canvassing a large area in search of only a handful of animals. But new technology and stronger partnerships with local communities have helped these h...

According to the CDC, about one in four adults has a fear of needles. Many of those people say the phobia started when they were kids. For some people, the fear of needles is strong enough that they avoid getting important treatments, vaccines or tests. That poses a serious problem for public health. Researchers have helped develop a five step plan to help prevent what they call "needless pain" for kids getting injections or their ...

Across the animal kingdom, menopause is something of an evolutionary blip. We humans are one of the few animals to experience it. But Sam Ellis, a researcher in animal behavior, argues that this isn't so surprising. "The best way to propagate your genes is to get as many offspring as possible into the next generation," says Ellis. "The best way to do that is almost always to reproduce your whole life."

The number of newborns born with syphilis – a serious sexually transmitted infection – has skyrocketed 755% from 2012 to 2021. These babies have congenital syphilis, which is when the infection is passed from mother to baby during pregnancy. It can have dire consequences if left untreated.

When Shohini Ghose was studying physics as a kid, she heard certain names repeated over and over. "Einstein, Newton, Schrodinger ... they're all men." Shohini wanted to change that — so she decided to write a book about some of the women scientists missing from her grade school physics textbooks. It's called Her Space, Her Time: How Trailblazing Women Scientists Decoded the Hidden Universe. This episode, she talks to Short Wave hos...
