Using CRISPR-Cas9 gene-editing technology, researchers modified the DNA of silkworms so that their silk-producing glands would instead create spider silk.
Chinese Scientists have introduced an innovative, green alternative to nylon and Kevlar
Production has been a real bottleneck. Also, I'm skeptical they got the actual strength right in this headline. It's strong, but it's still a biological material.
Edit: Yeah, it's half as strong per weight as a high-strength synthetic polymer, and weaker than normal steel on a volumetric basis. It stretches really far before it snaps though, which has implications for things like energy absorption.
Is it spider silk though? Can't have gene edited spider silk without gene edited spiders. This is gene edited silkworm silk. Or am I missing something about silk?
I'm excited for companies to never utilize this indestructible fabric in things like clothes and socks, backpacks, straps, and anything else that tends to break or fray.
