Human hair tested stronger than thicker fibers from elephants, boars and giraffes, providing clues to materials scientists hoping to make superstrong synthetic fibers. All mammals have hair ...

Rebecca Sutton, Ph.D., with the San Francisco Estuary Institute showed us how small the fibers can be; some are only visible with a microscope.

Scientists have synthesized spider silk from genetically modified silkworms, producing fibers six times tougher than the Kevlar used in bulletproof vests. The study is the first to successfully ...

Scientists in China have synthesized spider silk from genetically modified silkworms, producing fibers six times tougher than the Kevlar used in bulletproof vests. The study, published September ...
