Stronger than bone and twice as elastic as nylon, spider silk has already proven its usefulness to spiders, but now scientists are looking into its potential importance to humans as well. Research is underway around the world to fabricate the tenacious fibers in the lab, and scientists hope to someday outfit soldiers and police in bullet-proof vests made of mass-produced spider silk.
