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.

Anthropologists Have A Bone To Pick With New Skull Finding
There’s fresh drama in the field of human origins! A new analysis of an ancient hominid skull from China challenges what we thought we knew about our ancestral family tree, and its timeline—at least according to the researchers who wrote the paper. The new study claims that Homo sapiens, and some of our relatives, could have emerged at least half a million years earlier than we thought. But big claims require big evidence.Anthropologist John Hawks joins Host Flora Lichtman to piece together the details.Guest: Dr. John Hawks is an anthropologist and professor at the University of Wisconsin-Madison.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

Remembering Primatologist Jane Goodall
Jane Goodall, renowned primatologist, conservationist, and humanitarian, died on October 1 at the age of 91. Goodall was born in London in 1934, and her curiosity about the natural world led her to the forests of Gombe, Tanzania, where she made groundbreaking observations of chimpanzee behavior, including tool use. Her research challenged the accepted scientific perceptions of our closest relatives.Host Ira Flatow shares his memories of Dr. Goodall, including an interview from 2002 in which she discussed her life and work.Transcripts for each episode are available within 1-3 days at sciencefriday.com.
