How much lighter and stronger can bikes get? Scientists have managed to fuse metals -- titanium, aluminum, and zinc -- with spider's silk, resulting in a three-to-ten-fold increase in strength.
Turns out, Mother Nature is ahead of the materials-research game: marine polychaete worms already mix zinc into the proteins in their jaws for improved hardness, as do leaf-cutter ants and locusts.
I call dibs on the first titanium-infused silk bike frame. Sprockets fashioned from the mandibles of leaf-cutter ants and polychaete bearings please.
With such advanced materials, there's no way I could possibly get dropped.
