In a recent publication, researchers at University of Surrey and University College London suggest a new hypothesis, that the biological function of sleep is to allow for vital 'repair and maintenance' of the cells in our brain, so called neurons. The research also proposes that these repair functions can only occur if the rest periods of individual neurons are aligned precisely at a time scale of seconds or less. The hypothesis is published today (20 May) in Nature Reviews Neuroscience. http://medicalxpress.com/news/2013-05-theory-clues-vital-maintenance-role.html Neuroscience Tue, 21 May 2013 06:20:01 EST news288334475 Each day, an average of nine people are killed in the United States and more than 1,000 injured by drivers doing something other than driving. http://medicalxpress.com/news/2013-05-drivers-attention.html Health Tue, 21 May 2013 06:14:56 EST news288335683 (Medical Xpress)—A three-year multinational study has tracked and detailed the progression of Huntington's disease (HD), predicting clinical decline in people carrying the HD gene more than 10 years before the expected onset of symptoms. http://medicalxpress.com/news/2013-05-huntington-disease-trials-track.html Neuroscience Tue, 21 May 2013 05:52:53 EST news288334365 No new human cases of the H7N9 virus have been recorded in China for a week, national health authorities said, for the first time since the outbreak began in March. http://medicalxpress.com/news/2013-05-h7n9-cases-china-week.html Diseases, Conditions, Syndromes Tue, 21 May 2013 05:20:01 EST news288331389 A Nobel prize-winning scientist Tuesday played down "shock-horror scenarios" that a new virus strain will emerge with the potential to kill millions of people. http://medicalxpress.com/news/2013-05-nobel-laureate-flu-pandemic-scaremongering.html Diseases, Conditions, Syndromes Tue, 21 May 2013 05:01:38 EST news288331263 (AP)—The decade-old law that transformed the battle against HIV and AIDS in developing countries is at a crossroads.

Cross-resistance to colistin and host antimicrobials LL-37 and lysozyme, which help defend the body against bacterial attack, could mean that patients with life-threatening multi-drug resistant infections are also saddled with a crippled immune response. Colistin is a last-line drug for treating several kinds of drug-resistant infections, but colistin resistance and the drug's newfound impacts on bacterial resistance to immune attack underscore the need for newer, better antibiotics. http://medicalxpress.com/news/2013-05-resistance-last-line-antibiotic-bacteria-resistant.html Diseases, Conditions, Syndromes Tue, 21 May 2013 00:00:01 EST news288291710 A Mediterranean diet with added extra virgin olive oil or mixed nuts seems to improve the brain power of older people better than advising them to follow a low-fat diet, indicates research published online in the Journal of Neurology Neurosurgery and Psychiatry. http://medicalxpress.com/news/2013-05-mediterranean-diet-boost-ageing-brain.html Psychology & Psychiatry Mon, 20 May 2013 18:30:03 EST news288291448 More people are being diagnosed with eating disorders every year and the most common type is not either of the two most well known—bulimia or anorexia—but eating disorders not otherwise specified (eating disorders that don't quite reach the threshold to be defined as anorexia or bulimia), shows a study published online in BMJ Open. http://medicalxpress.com/news/2013-05-incidence-disorders-uk.html Psychology & Psychiatry Mon, 20 May 2013 18:30:02 EST news288291496 Bed sharing with parents is linked to a fivefold increased risk of sudden infant death syndrome (SIDS), even when the parents are non-smokers and the mother has not been drinking alcohol and does not use illegal drugs, according to a large analysis published online in BMJ Open. http://medicalxpress.com/news/2013-05-bed-parents-cot-death-fivefold.html Health Mon, 20 May 2013 18:30:01 EST news288291534 (Medical Xpress)—A research team, led by Jeremy Barr, a biology post-doctoral fellow, unveils a new immune system that protects humans and animals from infection. http://medicalxpress.com/news/2013-05-immune.html Immunology Mon, 20 May 2013 18:27:22 EST news288293224 (AP)—Federal investigators probing the hantavirus outbreak blamed for three deaths at Yosemite National Park recommend that design changes to tent cabins and other lodging run by private concessionaires first be reviewed by National Park Service officials. http://medicalxpress.com/news/2013-05-nps-hantavirus-response-policy.html Diseases, Conditions, Syndromes Mon, 20 May 2013 18:20:01 EST news288291216 Women who smoke during pregnancy increase the risk of both obesity and gestational diabetes, in their daughters, concludes research published in Diabetologia, the journal of the European Association for the Study of Diabetes.
