Biosteel is a new type of yarn that was developed for the soldier of tomorrow, who may be wearing suits made of spider silk and goat, lightweight and five times stronger than steel. It is the end product of a genetic marriage between spider and goat. It was developed at Nexia where scientists took a spider gene, injected it into a single cell of a goat egg and produced a goat named Willow.
