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.

The Human Obsession With Aliens Goes Way, Way Back
A video shown on Capitol Hill on September 9 reportedly shows an American hellfire missile attacking and simply bouncing off a UAP (the military term for a UFO). When videos like this come out, speculation about aliens often follows. But our obsession with aliens isn’t new—and it didn’t begin with 1950s alien invasion movies like “The Day The Earth Stood Still,” or even with Orson Welles’ “War of the Worlds” mock news bulletins of the 1930s.As science reporter Becky Ferreira writes in her upcoming book, First Contact: The Story Of Our Obsession With Aliens, humans have been fascinated with the potential for alien life for about as long we’ve been around. She joins Host Ira Flatow to discuss how our views of beings from other worlds changed throughout the millennia, and where we’re at now with scientific exploration of life beyond Earth.Plus, science journalist Umair Irfan joins Ira to share other stories from the week in science, including what’s going on in a decision-making brain, the trouble with vector-borne illnesses, and the unusual tale of an ant queen that breeds ants of another species.Read an excerpt of First Contact: The Story Of Our Obsession With Aliens.Guests:Becky Ferreira is a science reporter at 404 Media and author of First Contact: The Story Of Our Obsession With Aliens.Umair Irfan is a senior correspondent at Vox, based in Washington, D.C.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

A Delicious But Invasive Mushroom Could Affect Fungal Diversity
It all started harmlessly enough: People bought kits to grow mushrooms at home. But then, scientists in the upper Midwest noticed something strange. The golden oyster mushroom, which is not native to the United States, was thriving in local forests. Those homegrown mushrooms escaped our basements into the wild. Fungal ecologist Aishwarya Veerabahu joins Host Ira Flatow to discuss what impact these invasive mushrooms might have on the ecosystem.Plus, nightshade expert Sandra Knapp describes the evolution of the potato plant, and how a lucky crossbreeding millions of years ago may have given rise to the starchy tubers we eat today.Guests:Aishwarya Veerabahu is a fungal ecologist and PhD candidate at the University of Wisconsin-Madison.Dr. Sandra Knapp is a Merit Researcher at the Natural History Museum in London.Transcripts for each episode are available within 1-3 days at sciencefriday.com.
