- Human skin reinforced with spider silk - four times stronger than Kevlar
- Substance can stop a bullet
- Silk produced by goats, genetically altered to produce 'milk' made of webs
Human skin can stop a bullet - with a little help from genetically modified goats.
The skin is mixed with goat 'milk' from goats 'tweaked' to produce the same protein found in spider silk. Woven spider silk is four times stronger than Kevlar, the material used in bulletproof vests.
The 'silk' is layered with bio-engineered human skin grown in laboratory, and can withstand a direct impact from a bullet - although not one fired at full speed, yet.
