Science Friday Folgen

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 Lichtman in November 2025 to talk about his research, the odd jobs he worked along the way, and how he found a sense of belonging in science. Guests: Dr. Ardem Patapoutian is a professor and the Presidential Endowed Chair in Neurobiology at the Scripps Research Institute in La Jolla, California.

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 mine that is ancient squirrel poop. And, if you liked our poop jokes, you’ll want to hear how two different types of laughter are processed in the brain. Think big belly laughs versus polite chuckles in conversation. Ira chats with neuroscientist Sophie Scott about how these laughs originate and why we need them both. Guests: Dr. Tyler Murchie is a biomolecular archaeologist at the Hakai Institute in British Columbia and McMaster University in Ontario, Canada. Dr. Sophie Scott is a professor of cognitive neuroscience at University College London in England.  Transcripts for each episode are available within 1-3 days at sciencefriday.com.

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 Wainberg, who led a clinical trial for the drug.  Plus, ALS is a degenerative disease that causes patients to lose their ability to walk, swallow and eventually to breathe. Now, there’s a drug for a rare genetic form of ALS that can slow the progression or even reverse some of these symptoms. Ira talks with New York Times health and science reporter Pam Belluck about this new treatment. Guests: Dr. Zev Wainberg is a co-director of UCLA Health’s GI Oncology Program. Pam Belluck is a health and science reporter for The New York Times.
