A venomous primate with two tongues would seem safe from the pet trade, but the big-eyed, teddy-bear face of the slow loris (Nycticebus sp.) has made them a target for illegal pet poachers throughout the animal's range in southeastern Asia and nearby islands. A University of Missouri doctoral student and her colleagues recently identified three new species of slow loris. The primates had originally been grouped with another species. Dividing the species into four distinct classes means the risk of extinction is greater than previously believed for the animals but could help efforts to protect the unusual primate.

A study published by Université Laval researchers and their colleagues from the Canadian Forest Service reveals that the genome of conifers such as spruce, pine, and fir has remained very much the same for over 100 million years. This remarkable genomic stability explains the resemblance between today's conifers and fossils dating back to the days when dinosaurs roamed the Earth. Details of this finding are presented in a recent issue of the journal BMC Biology.

Stem Cell Research

Randomly distributed sticky spots which are integral to the development of stem cells by maximising adhesion and acting as internal scaffolding have been artificially recreated by experts from the University of Sheffield for the first time.

Molecular & Cell Biology

Every time a human or bacterial cell divides it first must copy its DNA. Specialized proteins unzip the intertwined DNA strands while others follow and build new strands, using the originals as templates. Whenever these proteins encounter a break – and there are many – they stop and retreat, allowing a new cast of molecular players to enter the scene.
