In 2009 the average uptake of the open access option for participating journals fell to 5.9%, compared with 6.7% in 2008. This reduction was due to a lower uptake amongst 11 new titles joining Oxford Open in 2009. On a like-for-like basis, the average uptake in 2009 for journals which entered the scheme prior to 2008 was stable (6.7%, compared with 6.8% in 2008).

Scientists have uncovered the flu's secret formula for effectively evolving within and between host species: balance. The key lies with the flu's unique replication process, which has evolved to produce enough mutations for the virus to spread and adapt to its host environment, but not so many that unwanted genomic mutations lead to the flu's demise (catastrophic mutagenesis). These findings overturn long-held assumptions about how the virus evolves.

In the quest to better understand how the brain chooses between competing behaviors necessary for survival, scientists at the University of Massachusetts Medical School and New York University have isolated two genes in the fruit fly Drosophila that work together to mediate the need to sleep and the need to eat. The study, which appears in the online version of Current Biology, offers insights that may be used to understand sleep-and metabolism-related disorders in humans.

In what has been hailed as a breakthrough, scientists from Columbia University Medical Center and Weill Cornell Medical College have outlined the molecular mechanism of membrane transport. The research shows how a protein transforms its shape to transport substances across the cell membrane in order to regulate transmission of the brain's messages across the synaptic gap from one neuron to another.
