Chimpanzees may have more smarts than humans, at least regarding short-term memories, new research suggests. A Japanese researcher presented a video showing the remarkable abilities of a chimpanzee named Ayumu, here at the annual meeting of the American Association for the Advancement of Science (AAAS) Thursday (Feb. 14). When the numbers 1 through 9 appeared randomly on a screen and then disappeared, the chimpanzee was able to recall the exact sequence and location of each number.
