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.

Modern genotyping technologies offer new opportunities to explore how genes influence health and disease, but also present the challenge of analyzing huge amounts of genetic and clinical data. With this in mind, investigators at the Lausanne Branch of the international Ludwig Institute for Cancer Research (LICR), the Swiss Institute of Bioinformatics (SIB) and the University Hospital of Lausanne have developed AssociationViewer, a computational tool that displays genetic differences between individuals on a large scale. Presented in the March 1st (Vol. 25/5) issue of Bioinformatics, the software is a public resource that will help scientists and physicians discover new genetic markers for diseases and other conditions.

The Max Planck Institute for Evolutionary Anthropology, in Leipzig, Germany, and the 454 Life Sciences Corporation, in Branford, Connecticut, will announce on 12 February during the 2009 Annual Meeting of the American Association for the Advancement of Science (AAAS) and at a simultaneous European press briefing that they have completed a first draft version of the Neandertal genome.

In a paper published in the journal Nature this week, Rutgers researchers Joachim Messing, Rémy Bruggmann, and a team of international collaborators have described the genome of sorghum, a drought-tolerant African grass.
