According to a new research report recently appearing online in The FASEB Journal, a diet that is high in fat and in sugar actually switches on genes that ultimately cause our bodies to store too much fat. This means these foods hit you with a double-whammy as the already difficult task of converting high-fat and high-sugar foods to energy is made even harder because these foods also turn our bodies into "supersized fat-storing" machines. http://www.physorg.com/news178806891.html Medicine & Health Mon, 30 Nov 2009 12:35:39 EST news178806891 (PhysOrg.com) -- When asked to inhibit their response to a "cocaine-cues" video, active cocaine abusers were, on average, able to suppress activity in brain regions linked to drug craving, according to a new study at the U.S. Department of Energy's Brookhaven National Laboratory. The results, to be published in an upcoming issue of NeuroImage, suggest that clinical interventions designed to strengthen these inhibitory responses could help cocaine abusers stop using drugs and avoid relapse. http://www.physorg.com/news178806768.html Medicine & Health Mon, 30 Nov 2009 12:33:19 EST news178806768 In the film, 'The Day After Tomorrow' the world enters the icy grip of a new glacial period within the space of just a few weeks.
