Bacteria can be hardy little creatures, thanks mostly to their strong cell walls that can protect them against drugs, viruses and other dangers. Finding ways to disarm these defenses is a key component of antibiotics, and now researchers at Harvard Medical School have identified a structural weakness that seems to be built into a range of bacterial species, potentially paving the way for a new class of widely-effective antibacterial drugs. read more
