The life-threatening bacteria called MRSA can cripple a hospital since it spreads quickly and is resistant to treatment. But scientists report that they are now making advances in a new technique that avoids antibiotics. Instead, they are using light to activate oxygen, which then wipes out antibiotic-resistant bacteria. The method also could be used to treat other microbial infections, and possibly even cancer. […]
