An international research team headed by two researchers from the University of Adelaide, Australia, has been awarded a US$900,000 grant to help unravel the phenomenon of "DNA looping".

Scientists from the U.S. Department of Energy (DOE) Joint Genome Institute (JGI) and the Bigelow Laboratory for Ocean Sciences have assembled high quality, contamination-free draft genomes of uncultured biodegrading microorganisms using a novel single cell genome sequencing approach. This proof of principle study, published in the April 23 edition of the journal PLoS One, offers researchers a new method to access and decipher the information embedded in genomes of interest with only minute quantities of DNA.

Los Alamos National Laboratory researchers have discovered a potential chink in the armor of fibers that make the cell walls of certain inedible plant materials so tough. The insight ultimately could lead to a cost-effective and energy-efficient strategy for turning biomass into alternative fuels.

Some 25 years after the AIDS epidemic spawned a worldwide search for an effective vaccine against the human immunodeficiency virus (HIV), progress in the field seems to have effectively become stalled. The reason? According to new findings from a team of researchers from the California Institute of Technology (Caltech), it's at least partly due to the fact that our body's natural HIV antibodies simply don't have a long enough reach to effectively neutralize the viruses they are meant to target.
