As a grad student, Suchitra Sebastian wasn’t sure she wanted to be a physicist. But when one of her experiments gave an unexpected result, she was hooked. Suchitra’s former PhD student Beng Sing Tan describes the late-night experiments that led to an “impossible” finding—a potentially new state of matter. Theoretical physicist Piers Coleman tells us about working on the edges of a scientific...

The James Webb Space Telescope (JWST) started collecting data nearly three years ago, and it has already transformed our understanding of the universe. It has spotted the earliest galaxies ever seen, and, closer to home, captured auroras around Jupiter. So what’s the latest from the JWST? In this live broadcast, Hosts Flora Lichtman and Ira Flatow talk with astrophysicist Macarena Garcia Marin,...

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 Lichtman and Ira Flatow discuss the science of aging...

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 million years. Paleontologist Stephen Poropat joins...

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. Host Ira Flatow is joined by oncologist Matthew Cooperberg and statistician Andrew Vickers, who studies prostate...

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. Neurologist Ken Kosick reflects on the early days of Alzheimer’s research,...

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 from New Scientist breaks down this reshuffling and...

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. Host Ira Flatow talks with reporter Ling Xin from...

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, Ruin and Redemption of Nature on the American...

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 Host Flora Lichtman about our history with bedbugs...
