How Conservation Efforts Brought Rare Birds Back From The Brink
The overall state of birds can seem rather grim. Almost a third of North American bird species are in decline, and in the last five decades, more than 100 species have lost over half of their populations. This is primarily due to lack of food—fewer insects to eat—and habitat loss, like the development of grasslands. But there’s a bright spot: Some birds that were once rare are now abundant, like the merlin, sandhill crane, and pileated woodpecker. Host Ira Flatow talks with biologist Tom Langen, who explains these birds’ remarkable comebacks, and discusses his conservation work to bring threatened fish species back from the brink. Guest: Dr. Tom Langen is a professor of biology at Clarkson University.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

Teamwork Between Species Is The Key To Life Itself
Codependency between humans gets a bad rap. But in nature, species often rely on each other for survival. While humans think they’re in control of relationships between other species, like dogs and even the yeast for our breads, the opposite is often true.Host Flora Lichtman speaks with ecologist Rob Dunn, whose new book, The Call of the Honeyguide, argues that mutualisms are the story of life itself.Read an excerpt of The Call of the Honeyguide: What Science Tells Us about How to Live Well with the Rest of Life.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

If An Asteroid Were Headed For Earth, Would We Be Ready?
You might remember news reporting from earlier this year that a 180-foot asteroid had about a 3% chance of hitting Earth in 2032. And if it did, it would unleash energy equivalent to hundreds of nuclear bombs. After further observations, astronomers revised that probability way down, to close to zero. So what is our current capability to spot Earthbound asteroids? And how are governments preparing to communicate and respond to a potential impact on a populated area?Joining Host Ira Flatow with some of the answers are Kelly Fast, from NASA's Planetary Defense Coordination Office, and Leviticus “L.A.” Lewis, former FEMA liaison for that office.Guests: Dr. Kelly Fast is the acting planetary defense officer in NASA’s Planetary Defense Coordination Office, based in Laurel, Maryland.Leviticus “L.A.” Lewis is a former FEMA liaison to the NASA Planetary Defense Coordination Office.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

A Trailblazing Geneticist Reflects On Her Life And Work
It’s common knowledge that many diseases and conditions have some kind of genetic link. But that wasn't always the case. In 1990, long before the Human Genome Project tied so many health issues to differences in genetics, researchers identified a gene called BRCA1. It was the first gene linked to a hereditary form of any common cancer. People with certain variants of BRCA1 stood a higher risk of developing breast and ovarian cancer than those without those mutations. Geneticist Mary-Claire King and her lab were the first to identify that gene. She joins Host Flora Lichtman to talk about her background, her research, and her approach to science.Guest: Dr. Mary-Claire King is an American Cancer Society Professor in the departments of Genome Sciences and Medicine at the University of Washington in Seattle.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

What The Label Of ‘Genius’ Tells Us About Our Society
What makes someone a genius? Are they the smartest, most creative, most innovative people? Those with the highest IQ? Who we consider a genius may actually tell us much more about what we value as a society than any objective measure of brilliance. A compelling or quirky life story often shapes who is elevated to genius status.Host Ira Flatow unpacks the complicated and coveted title of genius with Helen Lewis, author of The Genius Myth: A Curious History of A Dangerous Idea.Read an excerpt of The Genius Myth: A Curious History of A Dangerous Idea. Guest: Helen Lewis is a staff writer at The Atlantic, based in London, who writes about politics and culture.Transcripts for each episode are available within 1-3 days at sciencefriday.com.
