Bee strategy helps servers run more sweetly

ATLANTA (November 16, 2007) -- Honeybees somehow manage to efficiently collect a lot of nectar with limited resources and no central command after all, the queen bee is too busy laying eggs to oversee something as mundane as where the best nectar can be found on any given morning. According to n...
