“A petri dish at the University of Bayreuth in Germany holds swirls of artificial spider silk. Natural dragline silk, which forms the spokes and outer ring of a spider’s web, is tougher than steel fiber of the same diameter. The synthetic version cannot quite match that strength, but its durability and pliability make it ideal for fine sutures, replacement tendons, and tough yet lightweight textiles. To produce the silk, engineers equipped E.coli bacteria with the spider genes responsible for silk production. Each liter of bacterial culture produces just a few hundredths of an ounce of silk in three hours.”
