How A Woodpecker Pecks Wood, And How Ants Crown A Queen
If you’ve heard the hammering of a woodpecker in the woods, you might have wondered how the birds can be so forceful. What does it take to whack your head against a tree repeatedly, hard enough to drill a hole? A team of researchers wondered that too and set out to investigate, by putting tiny muscle monitors on eight downy woodpeckers and recording them with high-speed video as they pecked away in the lab.Integrative organismal biologist Nick Antonson, co-author of a report on the work, joins Host Flora Lichtmen to peck away at the mystery.Plus, you can take two ant eggs with the exact same genes, and one can grow up to be a queen, the other a worker. Neuroscientist and evolutionary biologist Daniel Kronauer joins Flora to share recent research into how an ant becomes a queen.Guests: Dr. Nick Antonson is an NSF postdoctoral research fellow in the department of ecology, evolution, and organismal biology at Brown University.Dr. Daniel Kronauer is the Stanley S. and Sydney R. Shuman Professor in the Laboratory of Social Evolution and Behavior at The Rockefeller University in New York.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

Memories Change. But Can We Change Them On Purpose?
Our memories make us who we are—just ask Barbra Streisand. But despite the lyrics in many popular songs, memories aren’t frozen in time. When we call them up, the details shift and change. And neuroscience research shows that we might be able to take that a step further—to manipulate our memories and even implant false ones.Neuroscientist Steve Ramirez joins Host Ira Flatow to explain how memory manipulation could revolutionize the way we treat brain disorders. They also discuss Ramirez’s book, How to Change a Memory: One Neuroscientist's Quest to Alter the Past, and how the sudden death of his friend and scientific collaborator made him rethink the role of memory.Guest: Dr. Steve Ramirez is an associate professor of psychology and brain sciences at Boston University and the author of How to Change a Memory.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

Bearded Vulture Nests Hold Trove Of Centuries-Old Artifacts
Bearded vultures build giant, elaborate nests that are passed down from generation to generation. And according to a new study, some of these scavengers have collected bits and bobs of human history over the course of centuries. Scientists picked apart 12 vulture nests preserved in Spain and discovered a museum collection’s worth of objects, including a woven sandal that could be more than 700 years old. Host Flora Lichtman talks with study author Ana Belen Marín-Arroyo, an archaeologist who studies ancient humans, about how the nests are giving us a glimpse into vulture culture as well as the lives of the people they lived beside.Guest: Dr. Ana Belen Marín-Arroyo is an archeologist and professor of prehistory at the University of Cantabria in Spain.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

Why The Bassist From Phish Is Funding Research Into ‘Flow State’
The band Phish has toured for over 40 years. One of the draws of their legendary live shows—which can go on for 8 hours—is finding moments of “flow,” when the band members lock into an improvised jam, finding new musical ideas in real time.Phish fans live for these transcendent moments, but so do the musicians—to the point that Mike Gordon, the band’s bass player, is funding scientific research to better understand flow state.Host Flora Lichtman sits down with Mike and his research collaborator, neuroscientist Greg Appelbaum, to unpack their research so far and how it’s helping to inform other neuroscience.Guests:Mike Gordon is bassist and co-founder of the rock band Phish. Dr. Greg Appelbaum is a professor in the department of psychiatry at the University of California, San Diego.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

Even Nobel Prize Winners Deal With Imposter Syndrome
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.
