  • The Nobel winner searching for deep-space neutrinos in Antarctica
    Oct 7 2026

    It’s Nobel Prize week, and this year's prize in physics went to Francis Halzen “for decisive contributions to the IceCube Neutrino Observatory and the discovery of high-energy neutrinos of astrophysical origin.” The IceCube is a massive neutrino detector that covers a cubic kilometer of Antarctic ice, and looks for high-energy neutrinos coming from deep space.

    In 2013, Ira spoke with physicist Francis Halzen about the decision to build the IceCube at the South Pole and the challenges of constructing a map of the cosmos with neutrinos.

    Guest:

    Dr. Francis Halzen is a professor of physics at the University of Wisconsin–Madison and the 2026 recipient of the Nobel Prize in physics.

  • How important ideas get reawakened, with David Byrne
    Oct 6 2026

    On Science Friday, we love to talk about ideas, especially ideas that have the power to shape the future. But there are plenty of groundbreaking ideas that almost don’t make it out of the lab or the art studio: ideas that are birthed but then fall into a deep slumber until, years later, they’re reawakened.

    Why this happens is the subject of the new book, “Sleeping Beauties: Why Good Ideas Go Dormant and How They Wake Up,” by David Bryne, artist, musician, and lead singer for Talking Heads. He joins Flora to explain.

    Read an excerpt from “Sleeping Beauties.”

    Guest:

    David Byrne is an artist, musician, and the lead singer for Talking Heads.

  • The History of Concrete with John Wilson
    Oct 5 2026

    John Wilson’s new documentary, “The History of Concrete,” has a subject matter that to most people may seem gray, drab, and boring. The film is anything but. Alongside facts about concrete’s reliance on dwindling sand reserves and New York City’s crumbling infrastructure, there are unexpected tangents. Following the idiosyncratic format of Wilson’s hit HBO show “How To,” he tells the stories of a struggling musician, a man who preserves tattoos, and a group of runners looping the same block for two months.

    Ira talks with documentarian John Wilson about the documentary and their shared appreciation of concrete.

    Guest:

    John Wilson is an NYC-based documentarian best known for his HBO series “How To with John Wilson.”

  • The tilcayo is the new wild cat on the block
    Oct 2 2026

    Big news for tiny cats: an itty-bitty three-pound spotted cat from Bolivia—called the tilcayo—is the first new wild cat species described in more than a hundred years.

    Tilcayo pics have been all over the news and social media, but there’s much more to tilcayo’s tale, including the surprising story behind its discovery.

    Flora chats with Paola Nogales-Ascarrunz, the biologist who worked for nearly 10 years to describe this flashy feline. They also discuss how Paola met the tilcayo, why it was so hard to classify, and what the reaction has been in Bolivia.

    Guest:

    Paola Nogales-Ascarrunz is a National Geographic Explorer and biologist leading the Bolivian Felid Research and Conservation Program. She’s based in Bolivia.

  • Are natural history museums going extinct?
    Oct 1 2026

    Leaders of the Academy of Natural Sciences of Drexel University say they can’t afford to keep the museum open to visitors. And there are rumors that another natural history museum, in Hays, Kansas, may be closing its doors. What happens to the collections, and are museums going the way of the dinosaurs?

    Jason Cryan, from the Natural History Museum of Utah, and Barbara Thiers, formerly of the New York Botanical Garden, join Host Flora Lichtman to discuss the challenges of running a natural history museum.

    Guests:

    Dr. Jason Cryan is The Sarah B. George Executive Director of the Natural History Museum of Utah, the largest natural history museum in America’s intermountain west.

  • Examining a new lunar crater + searching for signs of alien technology
    Sep 30 2026

    In 2024, scientists using instruments on board the Lunar Reconnaissance Orbiter spacecraft spotted a new large impact crater on the surface of the moon. Tyler Powell joins host Flora Lichtman to describe what they found, and what scientists are learning about the lunar surface from studying it.

    After, Sofia Sheikh describes different approaches to hunting for intelligent alien life through ‘technosignatures’. These are technological traces that could only be produced by intelligent life, like radio transmissions, industrial pollution, or city lights at night. Researchers from the SETI Institute have proposed sifting through lunar dust to look for tiny traces of a long-gone super advanced galactic civilization.

    Guests:

    Dr Tyler Powell is a planetary scientist at the Johns Hopkins Applied Physics Laboratory.

    Dr. Sofia Sheikh is a Technosignature Research Scientist at the SETI Institute.

  • Did the COVID pandemic stunt kids’ development?
    Sep 29 2026

    It’s a conversation at playgrounds and in classrooms: parents and teachers worry that kids who spent formative years at home during the COVID-19 pandemic are set back, emotionally, socially or academically. But what does science say? Did stay-at-home life permanently impact kids who lived through it? Joining host Flora Lichtman to dig into the research are child development experts Anna Johnson and Stephanie Jones.

    Guests:

    Dr. Anna Johnson, Professor of Psychology at Georgetown University in Washington D.C.


    Dr. Stephanie Jones, Professor of Early Childhood Development at the Harvard Graduate School of Education in Cambridge, Massachusetts.

  • How do concussions affect the brain?
    Sep 28 2026

    Football season is upon us and a new study is making headlines. Researchers found that roughly 1 in 4 NFL players will develop CTE, a neurodegenerative disease, in their lifetime. While most of us are not professional athletes, concussions are still a relatively common injury. Millions of Americans get concussions each year, but the exact number is hard to pin down because many people don’t seek treatment.

    So what are we learning about how concussions affect the brain? And how are the best practices for treatment changing? To answer those questions and more Flora sits down with Teena Shetty, a former neurologist for the New York Giants and author of the new book “Healing the Brain.”

    Guest:

    Dr. Teena Shetty is a former neurologist for the New York Giants and founder of the Teena Shetty MD Concussion Clinic. She is also an associate professor of clinical neurology at Weill Cornell Medical College and author of “Healing the Brain.”
