TEMPE, Ariz., Jan. 28 (UPI) -- U.S. researchers say studies of spider webs have revealed why the fiber that spiders spin is, weight for weight, at least five times as strong as piano wire.
Using a sophisticated but non-invasive laser light scattering technique, scientists at the University of Arizona have determined a wide variety of elastic properties of the silk in several intact spiders' webs, a university release reported.
