 It's in toughness that spider silk is extraordinary beyond any other natural materials and most manmade materials. When I started working on spider silk, almost all of the work had been done on this guy, on Nephila, on the Golden Orbevers. And me as a taxonomist, I have an appreciation for the amazing diversity of spiders out there. So there's a huge reservoir of hundreds of thousands of types of spider silk that have never been researched. Anything you can do with a strong lightweight fiber, you could do with spider silk. So anything from simply superior ropes to something like scaffolding for maybe for skin grafts, things for tissue engineering, possible use as a temporary tendons and all the things. We were lucky enough in Madagascar to discover a spider with these gigantic webs that can throw their silk lines across rivers and lakes up to 80, 90 feet. And it turns out that the silk that used to do that is extraordinary. It turns out to be the toughest spider silk known, which makes it the toughest known natural material. So I was part of that discovery through basically combining fields of biomechanics and taxonomy and discovery.
