Tomatoes come in all kinds of colors, sizes, and flavors. But what’s going on at the genetic level? What makes a tomato red or yellow? Tiny or giant?Researchers are mapping the genomes of 22 varieties of nightshades—the family of plants that includes tomatoes, potatoes, and eggplants. They located the genes that control the size of tomatoes and eggplants and then used CRISPR gene editing to grow bigger fruits without sacrificing flavor.Geneticist Michael Schatz joins Host Ira Flatow to talk about his latest research into nightshade genomes and the current state of genetically modified crops.Guest: Dr. Michael Schatz, professor of computational biology and oncology at Johns Hopkins University, based in Baltimore, Maryland.Transcript will be available after the show airs on sciencefriday.com.

Folge vom 19.05.2025The Leap: The Volcano WhispererAs a teenager living in St. Vincent, Richie Robertson saw first-hand what a volcanic eruption did to life on the island. Forty years later, he was the scientist the community turned to when the same volcano roared back to life. Richie’s colleague, Stacey Edwards of the UWI Seismic Research Centre, explains how Richie earned the trust of the community, and why it was important to have a Vincentian leading the way in a crisis.Guests: Dr. Richard Robertson, geologist at the UWI Seismic Research Centre Stacey Edwards, education & outreach manager at the UWI Seismic Research Centre“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 will be available after the show airs on sciencefriday.com.

Folge vom 16.05.2025Lesser Prairie Chicken May Lose Endangered Species StatusThe lesser prairie chicken was granted endangered species status in 2023. Now the Department of the Interior is moving to revoke those protections. What can this bird known for its flamboyant courtship rituals tell us about the Trump administration’s approach to environmental policy and protections for endangered species? Host Flora Lichtman is joined by Producer Shoshannah Buxbaum and Vox environmental reporter Benji Jones to talk about his reporting on the lesser prairie chicken and other science stories of the week including, Trump supporters in the wind energy sector, at-home cervical cancer screening, a new fossil from an ancient bird ancestor, the latest brood of cicadas emerging, and how flamingos eat with their heads upside down underwater. Guests:Benji Jones, environmental correspondent at VoxShoshannah Buxbaum, producer at Science FridayTranscripts for each segment will be available after the show airs on sciencefriday.com.

Folge vom 15.05.2025Tracking The Hidden Dangers Of Fighting FiresFirefighting is a career with an inherent cancer risk, but a full understanding of what those risks are has been elusive. An important registry designed to help understand the link between firefighters and cancer was taken offline on April 1 because of federal cuts, then restored six weeks later. Host Flora Lichtman discusses this with firefighter health researcher Sara Jahnke and reporter Murphy Woodhouse from Boise State Public Radio and the Mountain West News Bureau. Plus, pests and pathogens are ravaging keystone tree species in forests across the country. Flora discusses the innovative science behind breeding pest-resistant trees with Leigh Greenwood from The Nature Conservancy.Transcripts for each segment will be available after the show airs on sciencefriday.com.
