A leading cause of skin and wound infections once confined largely to hospitals and nursing homes, methicillin-resistant Staphylococcus aureus, or MRSA, is now cropping up in schools, farms and locker rooms, infecting otherwise healthy people. Researchers have used a computer program called OSPREY to predict how MRSA will adapt to a new experimental drug ahead of time, before the drug is tested on patients. Image Credit:
