We Finally Made Synthetic Spider Silk

TL;DR

Scientists genetically engineered silkworms to produce spider silk, unlocking its incredible properties.

Transcript

Maybe you’re scared of spiders. I mean, I am, so I’m not judging! But whether their many legs and eyes charm you or creep you out, the fact is that spider webs are a materials science miracle. The silk that spider webs are made of is stronger than steel by weight and stretchier at the same time, unlike anything we can mass produce. If we could make... Read More
