Ancient microbes in ice reveal natural antibiotic resistance, offering clues to fighting superbugs

Ancient microbes from a 5,000-year-old ice core reveal natural antibiotic resistance, offering clues to fighting superbugs. Scientists found these ancient bacteria, undisturbed for millennia, were resistant to ten modern antibiotics, demonstrating a long-standing evolutionary arms race between microbes. This discovery highlights the potential for new antibiotic development from unexplored natural sources, while also raising concerns about the release of dormant resistance genes due to melting ice.
