How PFAS From A Military Base Has Sickened Nearby Residents
For decades, residents of the small city of Newburgh, New York, were unknowingly drinking water contaminated with toxic PFAS—also known as forever chemicals. The source turned out to be firefighting foam used on a nearby air base that had seeped into streams and creeks, and ultimately the city’s main drinking water reservoir.Now, Newburgh is one of 10 sites that are part of a CDC-led study investigating the health effects of PFAS exposure. Early data out of Newburgh links PFAS with high cholesterol, high blood pressure, and heart disease. Host Flora Lichtman discusses the research with environmental epidemiologist Erin Bell and reporter Shantal Riley.Read our full story about what PFAS contamination has meant for Newburgh in English and in Spanish.Guests: Shantal Riley is an award-winning journalist and science writer, focused on environmental health.Dr. Erin Bell is an environmental epidemiologist at the University at Albany in New York.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

The Leap: And Then The Sub Went Silent
Oceanographer Victoria Orphan’s dream was coming true. She was sitting in the Alvin submersible, on one of its deepest science dives ever. But the trip was anything but smooth sailing. Victoria takes us inside the sub, where her dream turns nightmarish as things start to go wrong, and Alvin pilot Nick O’Sadcia works frantically to troubleshoot. Oceanographer Shana Goffredi, who’s also Victoria’s wife, tells us about the tense scene unfolding on the ship miles above, as they wait for word from the sub. “The Leap” is a 10-episode audio series that profiles scientists willing to take big risks to push the boundaries of discovery. It has premiered on Science Friday’s podcast feed every Monday since May 12. This is the final episode of the 2025 season.“The Leap” is a production of the Hypothesis Fund, brought to you in partnership with Science Friday.Transcript is available on sciencefriday.com.

How These Spiders At The Bottom Of The Sea Eat Methane
Researchers found a new sea spider with a giant nose, leg cannons, and—most remarkably—a novel way of surviving in the lightless, freezing environment miles below the sea surface. These oceanic arthropods are powered by methane that seeps out of the ocean floor.Biologist Shana Goffredi joins Host Flora Lichtman to tell us more about the discovery and explain how we’re connected to these little beasts.Guest: Dr. Shana Goffredi is a biology professor at Occidental College in Los Angeles, CA.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

As Disasters Escalate, What’s The Future Of FEMA?
President Trump has said that he wants to phase out FEMA, the Federal Emergency Management Agency, and move responsibility for dealing with major disasters to the state level. Since its creation in 1979, the agency has played a key role in coordinating emergency response nationally. Host Ira Flatow talks with Samantha Montano, an emergency management specialist and author of Disasterology: Dispatches from the Frontlines of the Climate Crisis, about the path forward for FEMA and how US emergency response efforts might change in the coming years. Plus, how much can extreme flooding events be attributed to climate change? Host Flora Lichtman breaks down the science with Andrew Dessler, Director of the Texas Center for Extreme Weather.Guests:Dr. Samantha Montano is an associate professor of emergency management at the Massachusetts Maritime Academy. Dr. Andrew Dessler is the Director of the Texas Center for Extreme Weather.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

Spaghetti Science And Mouth Taping Myths
Most pasta is made from just two ingredients—flour and water. For decades this humble food has prompted physicists around the world to try to understand its mysterious properties and answer questions like: Why does a stick of spaghetti break into three pieces and not cleanly into two? And why is cacio e pepe so hard to perfect? The answers reveal more about the building blocks of the universe than you might expect. Host Ira Flatow talks with Joseph Howlett, math writer at Quanta Magazine, and author of a recent story for the BBC about spaghetti science.And, if you frequent the wellness world on social media, you may have seen a trend popular with influencers: using adhesive tape to seal one’s mouth shut while sleeping. This is intended to help the sleeper breathe through their nose all night, which people claim has a slew of benefits including improved quality of sleep, reduced sleep apnea, a more defined jawline, and a brightened complexion. But should you add mouth taping to your nighttime routine? According to Dr. Linda Lee, physician and surgeon at Massachusetts Eye and Ear in Boston, you should be evaluated by a professional first.Dr. Lee joins Host Flora Lichtman to talk about the right way to start nose breathing, what the scientific literature says (and doesn’t say) about mouth taping, and how social media is changing the information patients seek from their physicians. Transcripts for each episode are available at sciencefriday.com.
