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 joins Host Flora Lichtman to talk about his research, the odd jobs he worked along the way, and how he found a sense of belonging in science.Guest: Dr. Ardem Patapoutian is a professor and the Presidential Endowed Chair in Neurobiology at the Scripps Research Institute in La Jolla, California. Transcripts for each episode are available within 1-3 days at sciencefriday.com.

Over the last five years, billions of people have received at least one dose of a COVID-19 mRNA vaccine. New research has found an unanticipated result of these vaccines: Cancer treatments are more effective for some vaccinated patients, and many live longer than their unvaccinated counterparts. This news comes at a time where the federal government is slashing funding for mRNA research. Host Ira Flatow speaks to lead study author Adam Grippin and vaccine expert Eric Topol.Guests: Dr. Adam Grippin is a radiation oncologist at the MC Anderson Cancer Center in Houston, Texas. Dr. Eric Topol is a cardiologist and genomics professor at the Scripps Research Institute in La Jolla, California.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

One of the biggest debates in the dinosaur world is what was happening right before they went extinct. Were they already declining, or would they have thrived if not for the asteroid? Two recent studies shed some light on this question: one that analyzes a trove of fossils from New Mexico and suggests there was more diversity in the Americas than previously thought, and another that reanalyzes a long-debated juvenile T. rex fossil and finds it’s likely a separate, smaller species.Host Ira Flatow is joined by authors on those separate studies, paleontologists Steve Brusatte and Lindsay Zanno.Guests: Dr. Lindsay Zanno is division head of paleontology at the North Carolina Museum of Natural Sciences in Raleigh, NC.Dr. Steve Brusatte is a paleontologist at the University of Edinburgh in Scotland.Transcripts for each episode are available within 1-3 days at sciencefriday.com.
