Now a group of women will test new interventions in aiding that recovery during a pilot study at Case Western Reserve University's Frances Payne Bolton School of Nursing. "Putting...

A bee's future as queen or worker may rest with parasitic fly

Strange things are happening in the lowland tropical forests of Panama and Costa Rica. A tiny parasitic fly is affecting the social behavior of a nocturnal bee, helping to determine which individuals become queens and which become workers. The finding by researchers from the University of Was...
