Blue light can selectively eradicate Pseudomonas aeruginosa infections of the skin and soft tissues, while preserving the outermost layer of skin, according to a proof-of-principle study led by Michael R. Hamblin of the Massachusetts General Hospital, and the Harvard Medical School, Boston. The research is published online ahead of print in the journal Antimicrobial Agents and Chemotherapy http://medicalxpress.com/news/2013-01-skin-soft-tissue-infections-succumb.html Diseases, Conditions, Syndromes Mon, 28 Jan 2013 16:13:36 EST news278612008 (Medical Xpress)—Researchers from the Université Bordeaux Segalen, France, and their Swedish colleagues have recently demonstrated that constant exposure to blue light is as effective as coffee at improving night drivers' alertness. Based on tests conducted in real driving conditions, the results have been published in the journal PLoS One. They could pave the way for the development of an electronic anti-sleep system to be built into vehicles. Before then, the scientists will be testing this equipment in a broader range of situations. http://medicalxpress.com/news/2012-11-coffee-blue-night-drivers.html Other Fri, 23 Nov 2012 06:27:19 EST news272874384 Adolescents can be chronically sleep deprived because of their inability to fall asleep early in combination with fixed wakeup times on school days. According to the Centers for Disease Control (CDC), almost 70 percent of schoolchildren get insufficient sleep—less than eight hours on school nights. This type of restricted sleep schedule has been linked with depression, behavior problems, poor performance at school, drug use, and automobile accidents. A new study from the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute shows that exposure to morning short-wavelength "blue" light has the potential to help sleep-deprived adolescents prepare for the challenges of the day and deal with stress, more so than dim light. http://medicalxpress.com/news/2012-10-short-wavelength-beneficial-stress-hormone-response.html Health Thu, 25 Oct 2012 10:50:05 EST news270380786 Researchers at Universite Laval have developed a blue light to help bleary eyed shift workers regulate their internal clocks and get the sleep they need when they need it. http://medicalxpress.com/news/2012-08-blue-workers-motorists-internal-clocks.html Health Wed, 01 Aug 2012 11:01:18 EST news263037673 Like a lot of Americans, Amalie Drury has grown very attached to her smartphone. http://medicalxpress.com/news/2012-07-electronic-screens-night-linked-loss.html Health Wed, 11 Jul 2012 10:50:01 EST news261221176 Parents have long tried to persuade children to eat their greens by promising it will give them better eyesight, but is there any truth to this age-old adage?
