Imagine this: You’re an astronaut, you’ve landed on the moon, and as you’re taking one small step for mankind, you kick up a bunch of lunar dirt. Now, tiny, jagged particles of dust are on your spacesuit, sticking to the spacecraft, getting in the machinery, and into your lungs. These are the kinds of problems planetary geologist Erica Jawin is trying to solve as NASA prepares for future moon bases.

And what will ...

Around 25 years ago, Ardem Patapoutian set out to investigate the fundamental biology behind our sense of touch. Through a long process of gene elimination, he identified a class of sensors in the cell membrane that turn physical pressure into an electrical signal. He changed the game in the field of sensation and perception, and in 2021 shared the Nobel Prize in Physiology or Medicine for his work. 

He joined Host Flora Licht...

Hundreds of thousands of years ago, deep in the mountains of the Yukon, a ground squirrel pooped. That scat stayed frozen for millenia—until very recently, when researchers thawed it out and realized it was a literal data dump. They found traces of a surprising number of animals and plants, providing a detailed snapshot of life during the last ice age. Flora talks with biomolecular archaeologist Tyler Murchie about the gold m...

Pancreatic cancer is among the most deadly forms of cancer, and it can be difficult to catch early. But there’s some good news: Clinical trials of a new drug called daraxonrasib found that it doubled the survival time of patients with advanced pancreatic cancer. And some oncologists are calling it a game changer—not just for pancreatic cancer, but potentially other forms of cancer too. Ira talks with oncologist Zev Wain...

On a hot summer day, there’s nothing better than a dip in a cold pool. But you know who can ruin that for you? A scientist who studies pool chemistry. What chemical reactions are happening in that swimming pool when the water comes into contact with our bodily fluids and skin products?

Environmental engineer Ernest Blatchley sits down with Flora Lichtman to discuss his findings after two decades of research, including how uri...

The federal Office of Management and Budget (OMB) has proposed rule changes that would bring a major shift in how scientific grants are awarded by U.S. government agencies. Under the current process, researchers submit grant proposals that are then vetted and scored by a committee of experts in that scientific field, with top-scoring proposals recommended for funding.

If its proposed changes are enacted, the OMB would insert a poli...

If you have arachnophobia, consider this your opportunity to try exposure therapy: A new study suggests that 415 million years ago, in modern-day England and Wales, a scorpion the length of a golden retriever was scurrying around, complete with 6-inch pincers. Flora talks with lead study author Richie Howard about the finding.

If you’re grossed out by a 3-foot scorpion, you’re not alone. But, scorpion researcher Lauren ...

The FDA recently approved a sunscreen ingredient called bemotrizinol, or BEMT, that’s been used in Europe and Asia for years. This is the first new sunscreen ingredient approved in the United States in over two decades. Meanwhile, skin cancer has become the most common cancer in the U.S. 

Flora discusses the chemistry of sunblock with a sunscreen chemist AJ Addae, and the regulatory process that led to this approval with...

If you watch sports, whether the recent NBA finals or the ongoing World Cup matches, you may have noticed that the athletes aren’t the only ones putting on a show. The announcers seem to be playing a beautiful game of their own, capturing the excitement and play-by-play of the game in a unique blend of sentence structure, elocution, and pitch. Linguists have even given this speech pattern a name: sports announcer talk.

There is a murderous crime spree happening right under—and perhaps inside—our noses. Killer microbes armed with weapons are eviscerating, assassinating, and detonating their fellow microbes. And the newest culprit? A protist that morphs into a cannibilastic supergiant when times get tough. 

Host Flora Lichtman talks with Glen D’Souza and Ben Larson, two detectives who study these micro-murders. They chat abou...

Do you ever hear a song that transports you to a specific place and time? This auditory wormhole has a name: musical daydreams. Music cognition expert Elizabeth Margulis studies why they happen, and what they tell us about our brains. She joins Host Flora Lichtman to discuss this phenomenon.

Guest:

Dr. Elizabeth Margulis is a professor and director of Princeton’s Music Cognition Lab. She’s also the author of “Tran...

Researchers just published details of a massive undersea graveyard of whales deep in the Indian Ocean. Spanning about 1,200 kilometers (745 miles), it contains whale remains dating back more than 5 million years—and at least five active whale fall sites still teeming with life. Fossil whale expert Nick Pyenson joins Host Flora Lichtman to discuss these findings.

Then, marine biologists Rachel Sipler and Sara Jobson join Ira F...

Big cats used to roam the entire United States. You might know them as mountain lions, pumas, cougars, or catamounts. Though they go by many names, they're actually all the same species. 

Their current population is mostly confined to the West, and part of Florida, though in recent years they’ve been spotted in other areas east of the Mississippi River. Most cougars were gone from the Northeast by the 1800s, with the las...

When Blue Origin’s New Glenn spacecraft exploded in an enormous fireball during a ground test a couple weeks ago, it sent shockwaves not only through the air, but through NASA’s timeline for the upcoming Artemis missions.

It also came at an especially bad time for Jeff Bezos’ rocket company—just days after it was awarded a slew of NASA contracts to deliver equipment to the moon. Blue Origin had also been exp...

‘Tis the season for porch beers and happy hours, and we’re taking on listener questions about how alcohol affects us. Like, is a glass of wine at dinner really good for you? And why do sugary drinks give us hangovers?

Joining Guest Host Jane Lindholm to answer these questions and more are brewer and chemist Tom Shellhammer and neuroscientist Jacqui Barker.

Guests:

Dr. Jacqui Barker is an associate professor in the Depar...

The 2026 World Cup will be the largest one yet, and FIFA is trying to make it the most high-tech, too. The federation has partnered with tech giant Lenovo to launch Football AI Pro, which is designed to analyze over 2,000 different metrics and deliver real-time insights to coaches, players, and analysts. Guest Host Jane Lindholm chats with ESPN writer Ryan O’Hanlon about how AI analytics actually play out in soccer.

Plus, how...

Elite athletes spend a lot of time training their bodies for strength, endurance, coordination, and precision. But what about their brains? Can psychology help athletes achieve peak performance? 

Joining Flora Lichtman to talk about this are professional climber Alex Honnold and Jessica Bartley, psychologist for U.S. Olympians and Paralympians. 

Guests: 

Alex Honnold is a professional climber, founder of the Honnold ...

If you’ve ever been a child, had a child, or seen a child face down in a supermarket aisle screaming, you know that parenting can be tough. But humans aren’t the only ones raising their young, so how do animals deal with toddlers that won’t follow directions or little ones that are constantly begging for snacks?

Parent and science journalist Elizabeth Preston, who wrote the book “The Creatures' Guide to Cari...

A few weeks ago, we talked to two sonic branding experts who compose music for household appliances. And we played for them a song “sung” by a washing machine that they didn’t really appreciate. But many of our listeners immediately identified the tune, a famous melody by 19th-century composer Franz Schubert.

And, as our guest tells us, it’s not just any tune—it’s one of Schubert’s most bel...
