New Booze Busting Device
Using optical technology,
engineers created a way to
measure the amount of
alcohol in a driver’s
skin. They use near-infrared
absorption spectroscopy to
measure blood alcohol

Gene Chip for Personalized Meds
The first in a new
generation of gene
microarrays, computer chips
that chemically or
electrically express DNA,
can predict how a person's
body will metabolize about

Stopping Strokes
To prevent strokes in
at-risk patients who suffer
from atrial fibrillation, an
abnormal heart rhythm,
researchers have devised a
mechanical alternative to
common drug treatments. In
the procedure, surgeons

Unraveling 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

Optical Scientists, Psychiatrists Develop Minimally Invasive Eye Test for Alzheimer's
Building upon a recent discovery that the same Alzheimer's disease process that goes on in the brain also occurs in the eye, researchers have developed a pair of optical tests that can determine the ... > more -
Doppler Sonography Helps Psychologists Measure Attention Levels
Psychologists are finding out that even when people try to focus on a task they tend to lose concentration within 40 minutes, and sometimes as little as 10 minutes. The studies are based on a new ... > 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 -
Engineers Create New Helmet to Help Troops Hear Better on Battlefield
Wearing a helmet can make it hard to figure which direction sounds -- such as gunfire -- is coming from. Soldiers in Iraq are using a new helmet, called the Advanced Combat Helmet, which is padded ... > more -
Neurosurgeonýs Drive Propels Him From Border Fence To Faculty
Physician scientist Alfredo Quinones has come a long way since illegally entering the United States. Today he is a faculty member at Johns Hopkins University. Quinones is a respected brain surgeon ... > more -
Scientists Show Blue Light Can Help Reset Sleep Cycle
Teenagers' morning drowsiness is often caused by out-of-tune body clocks, in a condition known as "delayed sleep phase syndrome." Scientists now say that timing exposure to blue light -- avoiding it ... > 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 -
Acousticians Improve Sound Quality of Cochlear Implants
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: speech recognition with a ... > more -
Neuroendocrinologists Unlock Chemical Trigger to Puberty
Researchers have discovered the precise chemical chain reaction that could be the much-sought-after puberty trigger: The KiSS-1 gene, which produces a protein in the hypothalamus, a part of the ... > more -
Psychobiologists Find Genetic Component in Children's Food Preference
In the first study to link taste genes to behavior in children, researchers looked at how natural variations in a recently discovered taste gene affected sensitivity to bitter tastes and food ... > more
