If you’ve ever been in the hospital for one of those annoying spider-bite like boils on your body, then you probably recognize the acronym MRSA and cringe. Methicillin-resistant Staphylococcus aureus (MRSA) is a bacteria that has been causing deadly infections in humans due to its resistance to most antibiotics. The bacteria most commonly lingers around hospitals, but can be found in gyms and schools as well.

With few medicines available to treat the infections caused by MRSA, scientists from Harvard’s Wyss Institute for Biologically Inspired Engineering and Boston University have been studying the biological makeup of this sneaky bacteria villian to find better ways to fight it. The researchers, using computer modeling and biotechnology of a similar bactera E. coli, found that simply adjusting the bacteria’s metabolism may be a way to kill it. Continue reading
