A new class of antibiotics - Acyldepsipeptides

Posted: 21 Jan 2014 07:00 AM PST

A new class of molecules called acyldepsipeptides — ADEPs — may provide a new way to attack bacteria that have developed resistance to antibiotics. Researchers at Brown and MIT have discovered a way to increase the potency of ADEPs by up to 1,200 times. Their findings appear in the Journal of the American Chemical Society.

New approach developed at MIT could generate power from sunlight efficiently and on demand

Posted: 21 Jan 2014 06:47 AM PST

A new approach to harvesting solar energy, developed by MIT researchers, could improve efficiency by using sunlight to heat a high-temperature material whose infrared radiation would then be collected by a conventional photovoltaic cell. This technique could also make it easier to store the energy for later use, the researchers say.
