But new research from Vanderbilt finds that these individuals--labeled as novelty seekers by psychologists--face an uphill battle in keeping their New Year's resolutions due to the way their brains process dopamine. The research reveals that novelty seekers have less of a particular type of dopamine receptor, which may lead them to seek out novel and exciting experiences--such as spending lavishly, taking risks and partying like there's no tomorrow. http://www.physorg.com/news149838584.html Medicine & Health Tue, 30 Dec 2008 05:49:44 EST news149838584 Laws banning marriage between first cousins are based on outdated assumptions about a high degree of genetic risk for offspring and should be repealed, according to a population genetics expert. http://www.physorg.com/news149249286.html Other Sciences Tue, 23 Dec 2008 10:08:06 EST news149249286 Traditionally, doctors have had no clear way to predict which of their patients might be headed down the road to chronic kidney disease (CKD).
