A pair of studies published by Cell Press on February 14th in the journal Cell sheds new light on genetic variation that may have played a key role in human evolution. The study researchers used an animal model to study a gene variant that could have helped humans adapt to humid climates, and they used whole-genome sequence data to identify hundreds of gene variants that potentially helped humans adapt to changing environmental conditions over time. The findings provide a road map for understanding human biological history as well as modern-day variability. http://medicalxpress.com/news/2013-02-reveal-genetic-variation-human-evolution.html Genetics Thu, 14 Feb 2013 13:24:09 EST news280070633 (HealthDay)—People who exercise along with taking statins to lower their high cholesterol levels can dramatically reduce their risk of dying, a large new study suggests. http://medicalxpress.com/news/2012-11-statins-lowering-cholesterol.html Cardiology Wed, 28 Nov 2012 17:00:25 EST news273339182 Could blind, buck-toothed, finger-sized naked mole-rats harbor in their brain cells a survival secret that might lead to better heart attack or stroke treatments? http://medicalxpress.com/news/2012-02-naked-mole-rats-lifesaving-clues.html Medical research Thu, 23 Feb 2012 15:39:37 EST news249233926
