Bacteria build stronger biosynthetic spider silk, protein by protein

Strong as steel and tougher than Kevlar, spider silk is one of nature's most impressive materials, but try as we might, we just haven't been able to harness it for our own use on a practical scale. Most synthetic versions aren't completely up to scratch, but researchers from Washington University in St. Louis have now engineered bacteria to produce biosynthetic spider silk that they say performs as well as the real stuff.
