Genetic tests on Chinese tallow trees from the United States and China prove the statesman did not import the tallows overrunning habitats along the Gulf Coast. Rice University's Evan Siemann, co-author of a study in the July issue of the American Journal of Botany, says descendants of Franklin's trees remain in a few thousand square miles of coastal plain in northern Georgia and southern South Carolina. The majority of troublemakers are linked to seeds brought to this country by federal biologists in the early 1900s.
Research by the Kohn lab, reported in the online journal Current Biology, analyzes a genetic mutation that has given the ordinary European house mouse resistance to common poison. Their work demonstrates how hybridization can occur naturally among animals, yielding non-sterile individuals with beneficial attributes. In this case, the result is a mouse that is resistant to warfarin, a toxic and, usually, deadly ingredient in many rodent poisons. The results were discussed on several sites including Science, Science News, Discovery News, and more. (read the paper)

This paper reports and analyses the draft genome sequence of the demosponge Amphimedon queenslandica. Sponges lie on the earliest branching lineage in the animal kingdom and thus have been important in studies of the origins of multicellularity. Comparative genomic analyses presented here provide significant insights into evolutionary origins of genes and pathways related to the hallmarks of metazoan multicellularity and to cancer biology.
