PHILADELPHIA Alcohol-impaired driving kills 29 people a day and costs $121 billion a year in the U.S. After years of progress in reducing alcohol-impaired driving fatalities, efforts began to stall in 2009, and fatalities started increasing again in 2015. With several studies demonstrating that drinkers cannot accurately estimate their own blood alcohol concentration (BAC), handheld alcohol breath testing devices, also known as breathalyzers, allow people to measure their own breath alcohol concentration (BrAC) to determine if they are below the legal limit of .08% before attempting to drive.
The latest generation of personal alcohol breath testing devices pair with smartphones. While some of these devices were found to be relatively accurate, others may mislead users into thinking that they are fit to drive, according to a new study from the Perelman School of Medicine at the University of Pennsylvania.
Sound sleep plays a crucial role in healing traumatic brain injuries
Sound sleep plays a critical role in healing traumatic brain injury, a new study of military veterans suggests.
The study, published in the
Journal of Neurotrauma, used a new technique involving magnetic resonance imaging developed at Oregon Health & Science University. Researchers used MRI to evaluate the enlargement of perivascular spaces that surround blood vessels in the brain. Enlargement of these spaces occurs in aging and is associated with the development of dementia.
Among veterans in the study, those who slept poorly had more evidence of these enlarged spaces and more post-concussive symptoms.

WASHINGTON (US): Getting a sound sleep at night is extremely important for one’s overall health, and now another benefit of a good night’s sleep has come to light. A new study has found that sound sleep plays a critical role in healing traumatic brain injury.
