How a spider spins key to fabric breakthroughs

This bio-assisted, rather than biomimicked technology, is an honorable testament to the amazing qualities of spider silk. Using GMO yeast might help Dan Widmaier of Bolt produce a bio-based fiber, the mesmerizing functions of spider silk lie not in the molecular make-up of the silk, but rather the method of extrusion through spider spinnerets, according to this New Yorker article. Combining the chemistry (achievable without GMOs) with the mechanics is the holy grail for truly emulating the spider’s genius.
