A plastic-like material that "flows" back together when cut or scraped could lead to self-healing bandages and cellphones that never stay scuffed, according to scientists in England. A supramolecular polyurethane created by scientists at the University of Reading repairs itself at body temperature and is not toxic to humans, suggesting it could lead to better wound dressings, among other uses. http://www.upi.com/Science_News/201...r-bandages-tougher-phone-cases/8261460123655/
