Blue light could treat superbug infections
Methicillin-resistant Staphylococcus aureus (MRSA), a bacterium that causes infection in various parts of the body, is often called a “superbug” thanks to its ability to dodge many common antibiotics. Researchers at Purdue University and Boston University have discovered that exposing the bug to blue light can render it defenseless against antiseptics as mild as hydrogen peroxide.
