Reviving Molecules: Scientists' Battle Against Superbugs

Scientists are using artificial intelligence-based computational methods to mine genetic information from extinct human relatives and long-gone ice age creatures in the search for new antibiotics. By analyzing the genetic information of Neanderthals, woolly mammoths, and giant sloths, researchers have identified small protein molecules with bacteria-fighting powers that could inspire new drugs to combat infections in humans. This innovative approach expands the way scientists think about molecular diversity and offers a potential solution to the global antibiotic resistance crisis. While the peptides discovered are not ready for use as antibiotics, the framework and tools developed by the research team provide a promising avenue for identifying antimicrobial molecules from the past.
