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. Transcripts for each episode are available within 1-3 days at sciencefriday.com.

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.  Subscribe to this podcast.
