Every year, the infectious "superbug" known as MRSA kills thousands of Americans who never should have died. But an international group of scientists think they may have found the key to shutting down the lethal bacteria that leads to these deaths and to countless less-serious infections. According to Jim Hedrick, the advanced organic materials scientist at IBM's Almaden Research Center in San Jose, CA, the potential now exists to make a kind of biodegradable nanoparticle that can be applied to the human body, either through injection or topical application, that could eradicate superbugs like MRSA. And looking down the line, Hedrick added, the team thinks other dangerous bacteria, like E-coli, could also be in its gun sights.
