To Stop Evolution: New Way Of Fighting Antibiotic Resistance Demonstrated By Scripps Scientists

...that mutation is a programmed stress response -- a survival mechanism. If the cell senses damage, and if the damage persists beyond its ability to repair it, the cell will turn on its mutation machinery and open the floodgates for evolution. Take the bacterium Escherichia coli for instance. When E. coli cell...
