(Newser) – Scientists have shed light on a new way to kill hospital superbugs like MRSA: literally shed light on them. A set of wavelengths called HINS-light acts by stimulating molecules in the bacteria, causing them to create chemicals that kill the germs. In trials, the process appears far more effective than “cleaning and disinfection,” the Daily Mail reports.

“The technology kills pathogens but is harmless to patients and staff, which means for the first time, hospitals can continuously disinfect wards and isolation rooms,” said an expert. The system uses violet-colored light, but researchers have also developed a white version appropriate for hospitals. Scientists call the idea, developed by Glasgow researchers, a “huge step forward.”
