These primates often make decisions faster that benefits others than themselves, according to a newly published University of Michigan study.

For decades, social scientists and biologists have sought to study primates because they are humans' closest living relatives. Chimpanzees can also be very...

Bigger = better: Big bees fly better in hotter temps than smaller ones do

Arizona State University researchers have found that larger tropical stingless bee species fly better in hot conditions than smaller bees do. Larger size may help certain bee species better tolerate high body temperatures. The findings run contrary to the well-established temperature-size "rule," which suggests that ectotherms -- insects that rely on the external environment to...
