Molecular Biologists Devise Strategy To Starve Brain Tumors
Brain tumor researchers have found that brain tumors arise from cancer stem cells living within tiny protective areas formed by blood vessels in the brain. Killing those cells is a promising ... > more -
Neurologists Use GPS For The Brain As Guide In Surgery
Neurosurgeons' jobs are made easier by a 3-D CT scan produced by an advanced imaging system. It produces a computerized image of blood vessels and surrounding soft tissue, which can be rotated for ... > more -
Psychologists Use fMRI To Understand Ties Between Memories And The Imagination
Psychologists have found that thought patterns used to recall the past and imagine the future are strikingly similar. Using functional magnetic resonance imaging to show the brain at work, they have ... > 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 -
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 -
Neurologists Use New Brain Scanning Device To Better Control Seizures
Doctors are now using a new kind of brain scan called magnetoencephalography (MEG), which measures brain activity in real time. In some cases, MEG can pinpoint the source of an epileptic seizure much ... > more -

GPS Navigation System Gives Acoustical Warnings
Human factors psychologists have teamed up with computer scientists to develop technology that can do the job of a seeing-eye dog -- help the blind walk around safely and without getting lost. The ... > more -
Cochlear Implants Work Better If Done On Both Ears
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 signals sent to the brain. ... > more -
New Jetliner Technology Emphasizes Human Factors
The new Boeing 787 Dreamliner will be the first of a new generation of commercial aircraft provided with a number of new technologies to increase comfort and reduce jet-lag. Human-factors engineers ... > more
