Some trees are coping with extreme heat surprisingly well
Rising temperatures could reduce trees' ability to photosynthesize. Scientists are trying to figure out just how close we are to that point.

Chimp chatter is a lot more like human language than previously thought
Chimpanzees combine hoots, calls and grunts to convey far more concepts than with single sounds alone. It may be a first among nonhuman animals.
