Sharks' Evening 'Rush Hour' Discovered

If sharks at the Pacific atoll of Palmyra used Google Maps, they'd see a lot of red dashes for traffic between 7 and 8 o'clock every evening. "Sharks are in trouble worldwide, so we need to be thinking about new tools and new technologies for studying them, and this one — which wasn't designed for scientific applications — worked very well," lead study author Douglas McCauley, a marine biologist at the University of California, Santa Barbara, said in a statement.
