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.

RFK Jr. Reshuffles CDC Vaccine Panel With Vaccine Skeptics
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 the other top science stories of the week, including Starlink’s leaky satellites, Earth’s possible past encounters with dark matter, IBM’s quantum computing plans, a device that can extract water from dry air, and how a paralyzed man was able to speak thanks to brain-controlled synthetic voice.Plus, nearly one in four Americans live within three miles of a Superfund site, places that are contaminated with hazardous waste and flagged for cleanup by the government. Amid sweeping cuts to science and environmental programs, the Trump administration appears to be prioritizing the cleanup of these polluted sites. But why? Host Flora Lichtman talks with science journalist Shahla Farzan about the Trump administration’s approach to cleaning up Superfund sites and what this means for impacted communities.Read Farzan’s full story about the move to expedite cleanup, and her past coverage of how floods can impact the areas surrounding Superfund sites.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

What’s Next For China’s Space Program?
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 South China Morning Post about the goals of China’s space program, and what might be ahead.Plus, astronomer Dean Regas describes his new “tactile astronomy” book, which seeks to bring stories of the constellations to young blind and low-vision readers. Guests:Ling Xin is a science reporter at the South China Morning Post based in Ohio.Dean Regas is an astronomer, host of the “Looking Up” podcast, and author of the new book All About Orion.Transcript is available on sciencefriday.com.

The Ruin And Redemption Of The American Prairie
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 Prairie, about the loss of biodiversity on the American prairie and those working to restore what remains.Guests: Dave Hage is a longtime environmental reporter and co-author of Sea of Grass: The Conquest, Ruin and Redemption of Nature on the American Prairie, based in St. Paul, Minnesota.Josephine Marcotty is a longtime environmental reporter and co-author of Sea of Grass: The Conquest, Ruin and Redemption of Nature on the American Prairie, based in Minneapolis, Minnesota.

Bedbugs Have Been Bugging Us Since Before Beds
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 and why they’re such prolific pests. Plus, the discovery of a new wasp that catches its prey… with butt flaps. Dr. Lars Vilhelmsen, curator at the Natural History Museum of Denmark in Copenhagen tells us all about it.Guests: Dr. Lindsay Miles is an entomologist at Virginia Tech.
