Spiders Spinning Bulletproof Vests
Scientists are trying to figure out what makes the fiber that spiders spin at least five times as strong as piano wire. Spider silk may eventually become a medical miracle that can produce skin grafts for burn victims, helps knit broken bones together and may one day even be used to make light weight bulletproof vests.
Spider silk is an exceptional biological polymer, related to collagen (the stuff of skin and bones) but much more complex in its structure. Chemists are studying its molecular structure in an effort to produce materials ranging from bulletproof vests to artificial tendons.
