Imaging studies of the brain when it is under the influence of alcohol reveal that different areas of the brain are impaired under high and low levels of alcohol, according to a Yale study published in Neuropsychopharmacology.
Godfrey Pearlson and Vince Calhoun, researchers in the Department of Psychiatry at Yale School of Medicine, used a statistical method to sort areas of the brain affected when persons were administered a placebo or two different doses of alcohol. The seven men and two women then "drove" using a simulated driving skill game.
"What we found is that when people were really intoxicated, they drove like they were really intoxicated and in a real vehicle," Pearlson said. "They speeded up, especially on corners, where most people slow down, and crashed more often into other vehicles." When mildly intoxicated, but below the legal alcohol limit, he said, the drivers seemed aware of the fact that they were impaired and corrected for the deficit. The researchers also found that alcohol had a profound effect on some, but not all, brain circuits activated in sober driving.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
