Penguins that died 44,000 years ago in Antarctica have provided extraordinary frozen DNA samples that challenge the accuracy of traditional genetic aging measurements, and suggest those approaches have been routinely underestimating the age of many specimens by 200 to 600 percent. http://www.physorg.com/news177083943.html Biology Tue, 10 Nov 2009 13:59:42 EST news177083943 A new paper published October 27 in PLoS ONE, the online, open-access scientific journal, unveils for the first time a method to accurately distinguish between all eight tuna species from any kind of processed tissue using genetic sequencing. http://www.physorg.com/news175807975.html Biology Mon, 26 Oct 2009 20:34:06 EST news175807975 Researchers at Ben-Gurion University of the Negev (BGU) have discovered that gene mutations that once helped humans survive may increase the possibility for diseases, including cancer. http://www.physorg.com/news165754102.html Medicine & Health Thu, 02 Jul 2009 11:49:10 EST news165754102 Parents and school nurses take note. Lice are a familiar nuisance around the world and vectors of serious diseases, such as epidemic typhus, in developing regions. New research indicates that lice may actually be quite unique in the animal world. In a study published online in Genome Research (www.genome.org), scientists have analyzed the mitochondrial genome of the human body louse and discovered that it is fragmented into many pieces - a remarkable finding in animals that will surely spark discussion about how it evolved and what advantages it might confer. http://www.physorg.com/news157653023.html Biology Mon, 30 Mar 2009 17:30:53 EST news157653023 A study reported in the August 8th issue of the journal Cell, a Cell Press publication, reveals the complete mitochondrial genome of a 38,000-year-old Neandertal. The findings open a window into the Neandertals' past and helps answer lingering questions about our relationship to them. http://www.physorg.com/news137334959.html Biology Thu, 07 Aug 2008 13:35:59 EST news137334959
