Bacteria cells are masters of adaptation and evolution, and by better understanding how they adapt and evolve, researchers hope to develop better drugs to fight microbial resistance, which is increasingly becoming a global public health threat. Researchers from the antimicrobial resistance interdisciplinary research group at the Singapore-MIT Alliance for Research and Technology (SMART) sought to understand the mechanisms bacteria use to adapt against stressors, and they discovered a new stress signaling system that sheds light on a new mechanism of antimicrobial resistance.
