How PFAS From A Military Base Has Sickened Nearby Residents
15 juli 2025 · 13 min
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. Lees meer
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.

Spaghetti Science And Mouth Taping Myths
10 juli 2025 · 18 min
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. Lees meer
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.

Ancient Bone Proteins May Offer Insight On Megafauna Extinction
24 juni 2025 · 19 min
Australia is known for its unusual animal life, from koalas to kangaroos. But once upon a time, the Australian landscape had even weirder fauna, like Palorchestes azael, a marsupial with immense claws and a small trunk. There was Protemnodon mamkurra, a massive, slow-moving, kangaroo-like creature. And Zygomaturus trilobus, a wombat the size of a hippo. They’re all extinct now, and researchers are trying to figure out why. Host Flora Lichtman talks with researcher Carli Peters about ZooMS, a technique that allows researchers to use collagen from ancient bone fragments to identify species, offering clues to those ancient extinction events. Peters recently described using the technique in the journal Frontiers in Mammal Science. Lees meer

A Dino’s Last Dinner And Eavesdropping Birds
18 juni 2025 · 21 min
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. Lees meer
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.

Bedbugs Have Been Bugging Us Since Before Beds
10 juni 2025 · 19 min
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. Lees meer

Are We Prepared To Fight ‘The New Polio’?
6 juni 2025 · 25 min
A mysterious disease called acute flaccid myelitis (AFM) has been appearing in emergency rooms for about a decade. The disease has caused otherwise healthy children to lose the ability to move their arms and legs, and some become completely paralyzed. AFM is caused by a virus that's a cousin of the polio virus, earning it the nickname "the new polio.” Journalist and physician Eli Cahan joins Host Flora Lichtman to explain what doctors have been observing, the research efforts toward developing a vaccine, and what this emerging disease reveals about our readiness for future outbreaks and pandemics. Lees meer
Read Cahan’s article about what fighting this “new polio” might look like as our healthcare infrastructure gets dismantled.
And, learning more about some non-cancerous cells may help researchers better understand how cancer progresses. When you think about how cancer spreads in the body, you’re probably thinking about cancer cells—they divide uncontrollably, form into tumors, and hide from the immune system. So, it makes sense that studying the behavior of these cells is critical to our understanding of cancer. But now, researchers are looking more closely at the non-cancerous cells that co-exist within tumors and the surrounding tissues. They make up what’s called the “colocateome.” Taking this more holistic approach to cancer research may help explain why some treatments don't work for all patients, and eventually may lead to more effective therapies. To better understand this expanding field, Host Ira Flatow talks with Sylvia Plevritis, a Stanford University cancer researcher.
Correction: In the second story of this episode, with Dr. Sylvia Plevritis, we misspoke and said, “Some of the hardest to treat tumors are actually non-cancer cells.” This was in reference to tumors that are mostly non-cancer cells, not entirely non-cancer cells.

How Science Communication Can Step Up Amid Federal Cuts
5 juni 2025 · 18 min
It’s a precarious time for science in the United States. Federal funding is being slashed, career scientists are being laid off, and researchers are considering leaving to work abroad. On top of that, public trust in science and experts has declined. Besides acknowledging the federal attacks on science, a lot of scientists are also asking themselves: What are we doing wrong? How do we engage the public? And what could we do better? Lees meer
Joining Host Flora Lichtman to dig through these questions is Felice Frankel, a science photographer and chemical engineer at MIT. She’s also the author of the upcoming book Phenomenal Moments: Revealing the Hidden Science Around Us, out this fall.

How Cannibalistic Tadpoles Could Curb Invasive Cane Toads
4 juni 2025 · 19 min
South American cane toads were brought to Australia in 1935 to help eradicate native beetles that were destroying sugar cane crops. The toads didn’t care much for the beetles, but they did spread across the coast of Queensland and beyond, with no natural predators to stop them. Their own deadly toxin devastated local reptiles along the way, and they now number over 200 million. Lees meer
Invasive biologists have long tried to curb Australia’s cane toad population. The newest approach uses CRISPR gene-editing technology to create cannibalistic “Peter Pan” cane toad tadpoles: tadpoles that don’t fully mature and instead feast on the tens of thousands of eggs that the toads produce.
How was this approach developed, and how do these researchers think about making a potentially massive change to the ecosystem? Biologist Rick Shine, who has led the effort, joins Host Flora Lichtman to discuss it. Later, science journalist Elizabeth Kolbert talks about her experience reporting on similar monumental efforts to control nature—and what they say about us.
Guests:
Elizabeth Kolbert is a staff writer at The New Yorker and author of Under a White Sky: The Nature of the Future (Crown, 2021). She’s based in Williamstown, Massachusetts.
