ScienceNOW : Dolphins and their close relatives that use sound to navigate can “steer” their sonar beams by merging two sound pulses together, a new study suggests. “It’s the acoustic equivalent of moving your eyes without moving your head,” says marine biologist Marc Lammers of the Hawaii Institute of Marine Biology at the University of Hawaii, Kaneohe. This ability may be unique in the animal kingdom, scientists say.
