A listener recently called in asking how they might get a pair of functioning web shooters so they could operate as a local Spider-Man. While web shooters (sadly) don’t exist, we can say that the ways real spiders use silk put Peter Parker’s powers to shame. Spiders can use their sticky threads to sail through the air, capture prey larger than them, and even live underwater. And scientists trying to harness those powers. Host Flora Lichtman chats with spider-silk aficionado Cheryl Hayashi about the wonders of silk, and Fiorenzo Omenetto shares how his engineering lab uses silk in the design of biomedical tools, like vaccines and sensors. Guests: Dr. Cheryl Hayashi is the senior vice president and provost of science at the American Museum of Natural History in New York City. Dr. Fiorenzo Omenetto is a biomedical engineer and director of the Silklab at Tufts University in Massachusetts. Transcripts for each episode are available within 1-3 days at sciencefriday.com.
