April Flowers for redOrbit.com - Your Universe Online Researchers have known for a long time that blind and visually impaired people rely on other senses. A new study led by the University of Southampton, however, now shows that they have the potential to use echolocation, similar to that of bats and dolphins, to determine the location of an object. The researchers examined how hearing, particularly the hearing of echoes, could help blind people with spatial awareness and navigation....

Lawrence LeBlond for redOrbit.com - Your Universe Online Blasting sound waves through the ocean to the seafloor in search of fossil fuels may do more harm than good, according to environmentalists. But the US Department of Interior has been considering giving large oil and gas companies permission to do just that.

Underwater Vessels Navigate With Ease With Help From ‘Sense-ational’ Invention
2012-12-12 11:01:26

Nanyang Technological University NTU scientists have invented a ℠sense-ational´ device, similar to a string of ℠feelers´ found on the bodies of the Blind Cave Fish, which enables the fish to sense their surrounding and so navigate easily. Using a combination of water pressure and computer vision technology, the sensory device is able to give users a 3-D image of nearby objects and map its surroundings. The possible applications of this fish-inspired sensor are...
