The best way to track a moving object with a flashlight might be to aim it to one side, catching the object in the edge of the beam rather than the center. New research at the Weizmann Institute of Science reveals that bats, which "Ëœsee' with beams of sound waves, skew their beams off-center when they want to locate an object. The research, which recently appeared in Science, shows that this strategy is the most efficient for locating objects. Dr. Nachum Ulanovsky and...

New research conducted at the University of Maryland's bat lab shows Egyptian fruit bats find a target by NOT aiming their guiding sonar directly at it. Instead, they alternately point the sound beam to either side of the target. The new findings by researchers from Maryland and the Weizmann Institute of Science in Israel suggest that this strategy optimizes the bats' ability to pinpoint the location of a target, but also makes it harder for them to detect a target in the first place. "We...

Only some bats and toothed whales rely on sophisticated echolocation, in which they emit sonar pulses and process returning echoes, to detect and track down small prey. Now, two new studies in the January 26th issue of Current Biology, a Cell Press publication, show that bats' and whales' remarkable ability and the high-frequency hearing it depends on are shared at a much deeper level than anyone would have anticipated"”all the way down to the molecular level. The discovery represents...

3-D imaging differentiates how various bats generate biosonar signals Researchers at The University of Western Ontario (Western) led an international and multi-disciplinary study that sheds new light on the way that bats echolocate. With echolocation, animals emit sounds and then listen to the reflected echoes of those sounds to form images of their surroundings in their brains. The team used state-of-the-art micro-computed tomography systems at the Robarts Research Institute in London,...
