Researchers at an American company working together with two U.S.universities may have found a solution to making artificial spider web.Using genetically modified silkworms,the company hopes that in the long run it will be able to make large quantities of very light,very strong fiber for medical as well as other uses.Additionally,because the manufacture of the artificial web is from living silkworms,the industry potentially would be non-polluting and less harmful to the environment.
