Silk is one of the most luxurious fabrics for clothing and bedding. Unlike cotton or linen, silk is made most commonly by insects—often the Bombyx mori, a domesticated moth that feeds on the leaves of mulberry trees. Humans have a 4,000-year history with the textile and the creatures that make it, as documented in the new book Silk: A World History.
Since silk has an unconventional origin as a secretion rather than a plant product, it has unique biological qualities that make it strong and enduring. And because it’s a natural protein fiber, it’s biodegradable, so scientists think it could have a future as a sustainable alternative to plastics and electronic parts.
Guest host Arielle Duhaime-Ross speaks with Dr. Aarathi Prasad, biologist and author of Silk: A World History. They discuss the ways humans have changed silk-creating creatures through domestication, future applications of the textile, and Prasad’s experience growing silkworms of her own.
