Super hearing in flies may improve hearing aid technology
...ately. "Beyond the mechanical processes of the ear drum
movement, we now know how the nervous system converts movement of the eardrums into information on sound direction," says Mason. The fly's ears act essentially as an extremely small, simple and sensitive directional microphone. Hearing aids tha...
Scientists using earstones to identify red drum nursery grounds
... Grant researcher Jay Rooker hopes to identify red drum
nursery grounds and determine the contribution of each area to the adult red drum
population. Earstones, or otoliths, can provide this information. Otoliths are part of the inner ear...
