Animals, Biology, Medicine, Science & Medicine

Dr Cat and Dilendra weave together the science of using silk from silkworms and spiders in medicine. Dilendra Wijesekara, a material scientist at Deakin University’s Institute of Frontier Materials, is developing a silk biomaterial for ear surgery. Dr Cat also shares some wild science involving getting goats to produce “spider silk milk”, and using a protein in spider silk as inspiration for cancer treatment. It’s a silky-smooth episode that showcases how strong, flexible, and fabulous nature can be.
