PZ Myers reviews a Nature paper on snake fang development and evolution, while Ed Yong reviews a PNAS paper on binge drinking tree shrews that somehow manage to stay sober.
And in news that illustrates the dynamic and self-correcting nature of science, the 2005 publication of the recovery T. rex soft tissue (see PZ Myers' review) may have been wrong. A recent PLoS ONE paper suggests that the observed structures, originally believed to be blood vessels and red blood cells, may in fact be a bacterial biofilm; Grrlscientist and Tara Smith offer reviews, while the Panda's Thumb post offers discussion, including comments from the first author on the PLoS paper.
