The results of a recent U.S. Navy study show that naval sonar and explosives use near California and Hawaii may be harming more marine life than previously thought.

Another recent animal study found that groups of wild chimpanzees appear to show cultural differences like humans. Studying 45 chimps from three groups, researchers noticed differences in their nut-cracking techniques. Researcher Christophe Boesch of the Max Planck Institute said in a statement, "In many ways, chimpanzees are very similar to us humans. By studying the similarities to our closest living relatives in their natural habitat in Africa, we have the unique opportunity to learn more about the evolutionary roots of culture, which is for us humans one of the key elements of our identity."
