Strength in Nature

This is a must-see special from NOVA highlighting nature's secret to creating very strong things: like the beak of a toucan, an abalone shell and a spider's web. It aired last night on PBS (premiered Jan 2011) and I found myself glued to the TV. Scientists are working hard to try to re-create some of nature's amazing strength to help improve existing technologies. One that I found amazing: scientists have been able to create genetically modified sheep to mass produce spider silk, which is reportedly stronger than kevlar!
