Researchers Use Lasers to Weld Spider Silk to Kevlar

Spiders aren’t domesticated, and attempts to make the silk proteins in other organisms haven’t been entirely successful.  The silk, once you have it, doesn’t always cooperate with modern manufacturing techniques.  But researchers in India figured out a way to get spider silk to play nicely with lasers. Under the right conditions, the silk itself helps amplify a laser’s power, to the point where it can either cut the silk in specific locations, or soften it to the point where it can be bent or welded.
