Ants produce their own antimicrobial chemicals to fight bacteria.
Wine has long been known for its disinfecting and cleansing properties. So can it kill flu and other bugs? And what about other types of alcohol?
This research could provide an answer to some of the problems posed by antibiotic resistance.
