Goats engineered to produce milk laden with spider-silk proteins may be able to turn human skin into a bulletproof shield, the Daily Mail reports. The milk’s proteins are extracted and woven into a material that is ten times stronger than steel. Finally, the material is cultured with human skin cells to create a skin that can stop bullets—at least those fired at reduced speeds. The synthetic skin was penetrable by a bullet shot from a .22-caliber rifle—the current standard for bulletproof vests.
But Dutch artist Jalila Essaidi, who created the skin with the help of the Forensic Genomics Consortium Netherlands, is happy with the results. "Even with the 'bulletproof' skin being pierced by the faster bullet, the experiment is, in my view, still a success," Essaidi told TechNewsDaily.
The skin will be on display at the National Natural History Museum Naturalis in Leiden, Netherlands, until January 8, 2012. (Hat tip to the Huffington Post.)
