Charlotte's Goat(Forbes.com): In a concrete bunker on a mothballed Air Force base in Plattsburgh, New York, two Nigerian dwarf goats named Mille and Muscade joyfully munch grass and slurp water. Oddly, they are protected from intruders by security guards and razor wire. Only 20 weeks old, these sister beasts warrant tight security because their milk is highly prized by the U.S. military. Their 70,000-gene chromosomes have been manipulated to include a gene from the orb weaver, a palm-size spider that spins the world's toughest natural material. Researchers are "growing" the spider's silk inside Mille and Muscade's mammary glands. These strands of silk, just 3 microns thick, are three times as tough as DuPont's bulletproof Kevlar. A woven cable as thick as your thumb can bear the weight of a jumbo jet.
