While the ways in which the cells of drug resistant bacteria become resistant are understood at the cellular level, until now, the bacteria's survival strategies at the population level remained unclear. A new study at Boston University and Harvard University reveals that a surprisingly small percentage of bacteria actually become highly resistant supermutants. In fact, most of the bacteria in their study survived without being resistant to the effective dose of antibiotics in the environment.

In a major leap that could transform solar power from a marginal energy source into a mainstream energy source, MIT researchers have overcome a major barrier to large-scale solar power: storing energy for use when the sun doesn't shine. Until now, solar power has been a daytime-only energy source, because storing extra solar energy for later use is prohibitively expensive and grossly inefficient. MIT researchers have hit upon a simple, inexpensive, highly efficient process for storing solar energy.
