World Space Week And Promising Climate Tech Companies
It’s World Space Week, and we’re fueling up the rocket for a tour of some missions and projects that could provide insights into major space mysteries. Astrophysicist Hakeem Oluseyi joins Host Flora Lichtman to celebrate the wonders of space science, from the recently launched IMAP, which will study the solar environment, to the new Vera Rubin Observatory, and big physics projects like LIGO. Plus, the latest in climate tech: MIT Technology Review has published its annual list of climate tech companies that show great promise in work ranging from producing sodium ion batteries to recycling rare earth magnets. Host Ira Flatow talks with climate reporter Casey Crownhart about trends in climate tech and what companies she’s excited about.Guests: Dr. Hakeem Oluseyi is an astrophysicist and author of the upcoming book, Why Do We Exist? The Nine Realms of the Universe That Make You Possible, and host of the video podcast “Particles of Thought.”Casey Crownhart is a senior climate reporter for MIT Technology Review based in New York City.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

The Story Behind The Largest Dam Removal In U.S. History
The Klamath River, which runs from southern Oregon to California, used to be a top salmon run. But after a series of hydroelectric dams was installed along the river around 100 years ago, salmon populations tanked.This is the prologue to a remarkable story of a coalition that fought to restore the river. Led by members of the Yurok Nation, who’ve lived along the river for millennia, a group of lawyers, biologists, and activists successfully lobbied for the removal of the dams. The fourth and final dam was taken down last year.Joining Host Flora Lichtman to go behind the scenes of the dam removal and what’s happened since are Amy Bowers Cordalis, former general counsel for the Yurok Nation and author of the forthcoming book The Water Remembers: My Indigenous Family’s Fight to Save a River and a Way of Life; and Barry McCovey Jr., director of the Yurok Tribes Fisheries Department.Read an excerpt from The Water Remembers: My Indigenous Family’s Fight to Save a River and a Way of Life.Guests:Amy Bowers Cordalis is an attorney, member of the Yurok Nation, and author of The Water Remembers: My Indigenous Family’s Fight To Save A River And A Way Of Life. Barry McCovey Jr. is the director of the Yurok Tribes Fisheries Department, based in Klamath, California.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

How Archaeologists Try To Smell, Hear, And Taste The Past
Archeologists in movies have a reputation for being hands-on, like Indiana Jones unearthing hidden treasure, or Lara Croft running through a temple. Archeology in real life tends to be a bit more sedentary. But some archeologists are committed to getting their hands dirty—even recreating the stinky, slimy, and sometimes tasty parts of ancient life.Science writer Sam Kean enmeshed himself in the world of experimental archaeology for his new book Dinner with King Tut: How Rogue Archaeologists are Recreating the Sights, Sounds, Smells, and Tastes of Lost Civilizations. He joins Host Ira Flatow to discuss making stone tools, launching catapults, and DIY mummies.Guest: Sam Kean is a science writer and author of Dinner with King Tut: How Rogue Archaeologists are Recreating the Sights, Sounds, Smells, and Tastes of Lost Civilizations.

Moth Survival Strategies And A Rodent Thumbnail Mystery
If you’re a moth trying to stay uneaten, there are competing strategies. Some moths rely on camouflage, trying to blend in. Other moths take the opposite approach: They’re bold and bright, with colors that say “don’t eat me, I’m poison.” Biologist Iliana Medina joins Host Flora Lichtman to describe a study that placed some 15,000 origami moths in forests around the world to investigate which strategy might work best. Then, mammologist Anderson Feijó and evolutionary biologist Rafaela Missagia join Flora to dive into another evolutionary conundrum: why so many rodents have thumbnails. Guests: Dr. Iliana Medina Guzman is a Senior Lecturer in the School of BioSciences at the University of Melbourne in Australia.Dr. Anderson Feijó is a mammal curator at the Field Museum in Chicago. Dr. Rafaela Missagia is an assistant professor at the University of São Paulo in Brazil.Transcripts for each episode are available within 1-3 days at sciencefriday.com.
