Researchers hack silkworm genome to get spidery silk

Ars Technica: "By a number of measures, spider silk is one of the toughest materials around. It's also light weight and (obviously) biocompatible. Unfortunately, it's also extremely hard to produce in any sort of usable quantity. Now, researchers have figured out a way that might help us make a lot more of something almost as good: they've engineered some DNA that encodes a hybrid of silkworm and spider proteins, and gotten silkworms to produce it."
