Helping The Deaf Hear
Otolaryngologists develop a
new, implantable hearing
aid. It works with a
transmitter worn behind the
ear that sends sound
vibrations from her deaf
side through the skull to
her good ear. It's called

Two Ears Are Better Than One
Unlike other acoustical
devices such as hearing
aids, which just amplify
sounds, cochlear implants
mimic what happens inside
the ear, changing sound
waves into electrical

Why I Hate Anchovies
An exhibit at San
Francisco's Exploratorium
explains the science of
cooking and eating, and in
particular how we taste
food. Our sense of taste
comes from a combination of
smell receptors in the nose

3-D Hearing Aid
In a new study, 34
normal-hearing and 18
cochlear-implant subjects
were tested on three
speech-perception tasks
known to be notoriously
difficult for
cochlear-implant users:

Electrical Engineers Develop Glove That Translates Sign Language
A new high-tech glove enables the translation of sign language into written text, facilitating communication for the hearing or speech impaired. The glove senses movements of the hand and fingers, ... > more -
Colors Are Key To Keeping Your Eyes On The Game
People can focus on more than three items at a time if those items share a common color. Psychologists at Johns Hopkins University have demonstrated that when players wear uniforms, it allows ... > more -
Acoustic Study Shows Safe Listening Levels
Loud, sustained sound can damage tiny hairs in the cochlea, and yet 80 percent of people listen to personal music devices at dangerous levels above background noise, a study by acousticians shows. ... > more -
Cognitive Psychologists Show Conversations Lower Visual Abilities
A study showed that the part of the brain that controls vision becomes less active when people focus on something visually while having a conversation -- underscoring the hazards of talking on your ... > more -
Vision Researchers Test Theory on Visual Orientation
Vision researchers suspect that people who do not need maps to find their way may be remembering visual landmarks. To test this theory, the scientists are having volunteers navigate through a virtual ... > more -
MRIs Peek into the Brains of Synesthesia Patients
Cognitive neuroscientists have now documented hundreds of cases of synesthesia -- the condition in which one sense triggers the response of a different one. Using functional magnetic resonance ... > more -
Physiologists Investigate The Role Of Perception In Motion Sickness
The cause of motion sickness is being investigated by a researcher with a new idea: that the cause is movement, not perceptual differences. A series of motion-sickness-inducing tests shows that those ... > more -
Pediatric Neurologists Use MRI to Understand How Strokes Impair Verbal Abilities
Children who have speech-impairing strokes often learn to talk again, while adult stroke victims can lose their verbal abilities for good. By giving reading and verbal tests inside the MRI, ... > more -
Sea Urchins' Genetics Add To Knowledge Of Cancer, Alzheimer's And Infertility
Researchers are using the sea urchins to study and understand diseases like cancer, Alzheimer's disease, Parkinson's disease and muscular dystrophy. Although they are invertebrates, the creatures ... > more -
Neurosurgeons Cut Surgical Procedure Time with New Device
In a method called deep brain stimulation, certain movement disorders are treated by implanting wires in the brain that deliver electrical signals. The surgical procedure can last up to eight hours, ... > more
