According to a fascinating new study, curly locks are better than straight hair at keeping your scalp cool. Researchers shone bright lights on three different manikins—one with no hair, one with loosely curled hair and another with tight curls.
Solar radiation bounced off the tightly curled hair, and less heat reached the manikin’s scalp than the straight haired manikin. The manikin with loose curls was right in the middle. The research is part of an effort to better understand the role of hair texture in human evolution, as humans are the only mammals with the majority of body hair atop our heads.
Ira talks with Dr. Tina Lasisi, a postdoctoral researcher in the department of quantitative and computational biology at the University of Southern California, and incoming assistant professor of Anthropology at the University of Michigan.
Unprecedented Avian Flu Outbreak Continues
Avian influenza has been circulating for decades among wild birds, but the US is now experiencing the worst outbreak in its history. That’s because of a specific strain of highly pathogenic avian influenza, which has left around 60 millions birds—mostly poultry—dead. This has implications for us all, whether you’re frustrated about the price of eggs, worried about your backyard chickens, or concerned about yet another threat to public health.
In this live call-in, Ira talks with Ashleigh Blackford, the California Condor Coordinator at the US Fish & Wildlife Service about the initiative to vaccinate California condors—the first of its kind to vaccinate any bird.
Then Ira explores what this outbreak means for other wildlife, poultry, and for us. He talks with Dr. Kristy Pabilonia, professor and director of the Veterinary Diagnostics Laboratories at Colorado State University, and Dr. Richard Webby, director of the WHO’s Collaborating Center for Studies on the Ecology of Influenza in Animals and Birds and a researcher at St. Jude’s Children’s Research Hospital.
