Brain Scan
Researchers at University of Toronto and Bloorview, Canada's largest children's rehabilitation hospital, have developed a technique that uses infrared light brain imaging to decode preference. When children with disabilities can't speak or gesture to control their environment, they may develop a learned helplessness that impedes...

Diagnosing Brain Aging
UCLA scientists have used brain-scan technology, along with patient-specific information on Alzheimer's disease risks, to help diagnose brain aging before symptoms appear. The researchers used positron emission tomography (PET), which allows the revealing of plaques and tangles, the hallmarks of neurodegeneration. The PET...

Portable Ultrasound Device
Cornell University graduate student George Lewis is trying to shrink ultrasound devices to make them practical for any hospital or medical research lab. Lewis has developed a palm-sized, battery-powered ultrasound device powerful enough to stabilize a gunshot wound or deliver drugs to brain cancer patients. Current...
Briefs: Physical Sciences
Solid-electrolyte-based amperometric sensors for measuring concentrations of CO2 in air are being developed for use in detection of fires, environmental monitoring, and other applications where...
