Ever noticed how some people get to their 80s and 90s and continue to be healthy and active? They spend their days playing mahjong, driving to lunch, learning shuffle dancing, and practicing Portuguese. Those are “super agers,” seniors who stay fit well into old age. How do they do it? Is it luck or genetics? In this live broadcast, Hosts Flora Lic…

While there are a lot of dinosaur fossils, and a lot of plant fossils, the precise connection between the two has been something of a mystery. Now, researchers report that they’ve found what’s called a cololite, fossilized gut contents, in the remains of a sauropod—a massive, long-necked plant-eater. The dino’s last meal dates back 95 to 100 millio…

Last month, former President Joe Biden announced that he had been diagnosed with an aggressive form of prostate cancer. The news sparked a larger conversation about what exactly the best practices are to screen for prostate cancer. Turns out, it’s more complicated than it might seem.

Biochemist Virginia Man-Yee Lee has spent a lifetime in the lab, figuring out what happens in the brains of people with neurodegenerative diseases. She’s made key discoveries about Parkinson's, ALS, and Alzheimer's.The secret to her success? Happiness. “If you're not happy, you don’t know what you’re capable of,” Lee says.

On Monday, US Health Secretary Robert F. Kennedy Jr. fired all 17 members of the panel that advises the CDC on who should get certain vaccines and when. Then on Thursday, he appointed eight new members, some of whom have been critical of vaccines in the past. So who exactly is new on the panel and how are medical experts reacting? Sophie Bushwick f…

This week, China’s Tianwen-2 spacecraft sent back its first image from space. It’s headed to a rendezvous with the asteroid Kamoʻoalewa, one of Earth’s “quasi-moons,” where it will collect samples in 2026. The mission comes after several successful lunar missions, including a lunar rover and a sample return mission from the far side of the moon. Ho…

The prairie might just be the most underappreciated landscape in the United States. Beginning in the early 1800s, the majority of these grasslands were converted into big industrial farms. Now, some unaffectionately refer to it as “flyover country.” Host Ira Flatow talks with Dave Hage and Josephine Marcotty, authors of Sea of Grass: The Conquest, …

Bedbug infestations are not just a modern problem—these pests have been with early human ancestors for 245,000 years, causing problems long before the invention of beds. Lindsay Miles, an entomologist at Virginia Tech, has found that changes in bedbug population size mirrored those of humans, proving they might be our first pest. Miles talks with H…

Manu Prakash is many things—biologist, engineer, inventor, philosopher—but what he isn’t is conventional. Following his instincts has led Manu to his most ambitious project yet: mapping the whole tree of life, with the help of everyone on this planet. Step one: make a cheap microscope anyone can use. Foldscope co-inventor Jim Cybulski describes the…

A mysterious disease called acute flaccid myelitis (AFM) has been appearing in emergency rooms for about a decade. The disease has caused otherwise healthy children to lose the ability to move their arms and legs, and some become completely paralyzed. AFM is caused by a virus that's a cousin of the polio virus, earning it the nickname "the new poli…

It’s a precarious time for science in the United States. Federal funding is being slashed, career scientists are being laid off, and researchers are considering leaving to work abroad. On top of that, public trust in science and experts has declined. Besides acknowledging the federal attacks on science, a lot of scientists are also asking themselve…

South American cane toads were brought to Australia in 1935 to help eradicate native beetles that were destroying sugar cane crops. The toads didn’t care much for the beetles, but they did spread across the coast of Queensland and beyond, with no natural predators to stop them. Their own deadly toxin devastated local reptiles along the way, and the…

Birding is a hobby that attracts a very particular group of people: the kind who get up at sunrise, go into the woods, and wait for hours for a little tiny feathered friend to fly past.
