What We’re Learning From The James Webb Space Telescope
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, deputy project director for the James Webb Space Telescope.Guest: Dr. Macarena Garcia Marin is an astrophysicist and instrument scientist for the European Space Agency. She’s also deputy project director for the James Webb Space Telescope.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

How ‘Super Agers’ Stay Sharp And Active Longer Than Their Peers
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 with two experts on the topic, cardiologist Eric Topol and neuroscientist Emily Rogalski.Guests:Dr. Eric Topol is an author, practicing cardiologist at the Scripps Clinic, and a genomics professor at the Scripps Research Institute in La Jolla, California.Dr. Emily Rogalski is a clinical and cognitive neuroscientist, and the director of the Healthy Aging & Alzheimer’s Research Care Center at the University of Chicago.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

A Dino’s Last Dinner And Eavesdropping Birds
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 Host Flora Lichtman to dig into the mysteries of a dinosaur’s tummy.And, for prairie dogs, communication is key. The rodents’ yips and barks can warn when danger is near—and not just to other prairie dogs. A new study suggests that birds called long-billed curlews are eavesdropping on this chatter to learn when a predator is lurking nearby. Using speakers and a taxidermied badger on wheels, ornithologists are untangling the social dynamics of black-tailed prairie dogs. Host Flora Lichtman talks with study author Andrew Dreelin about this eavesdropping behavior and what it means for conservation.Guests:Dr. Stephen Poropat is a paleontologist and deputy director of the Western Australian Organic and Isotope Geochemistry Centre at Curtin University in Perth, Australia.Andrew Dreelin is a research fellow with the Smithsonian Conservation Biology Institute and a PhD candidate at Northern Illinois University.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

What Are The Best Practices For Prostate Cancer Screening?
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 cancer screening, to help unpack those complexities.Guests:Dr. Matthew Cooperberg is a urologic oncologist and professor at the University of California, San Francisco.Dr. Andrew Vickers is a statistician who studies the efficacy of prostate cancer screening at Memorial Sloan Kettering Cancer Center based in New York City.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

The Leap: Garbage In, Garbage Out
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, and neurologist Alice S. Chen-Plotkin, a former postdoc in Virginia’s lab, gives us a fly-on-the-wall look at the unusual research partnership between Lee and her husband John Trojanowski.“The Leap” is a 10-episode audio series that profiles scientists willing to take big risks to push the boundaries of discovery. It premieres on Science Friday’s podcast feed every Monday until July 21. “The Leap” is a production of the Hypothesis Fund, brought to you in partnership with Science Friday.Transcript is available on sciencefriday.com.
