The International Polar Year (IPY) concluded in March 2009 with a tangible legacy in the form of a network of databases on marine biodiversity that will serve as clearinghouse for all biodiversity-related data gathered since the very first Antarctic research expeditions. The network gathers data describing the species themselves as well as information about their collection history, allowing scientists and conservationists to access the first rigorous census of Antarctic marine life. Created by the Scientific Committee on Antarctic Research's (SCAR), an inter-disciplinary committee of the International Council for Science, the Marine Biodiversity Information Network (SCAR-MarBIN) is a collaborative web portal that provides free and open access to information on Antarctic marine biodiversity (www.scarmarbin.be). The portal started as a major Belgian contribution to the IPY, but grew into an international collaborative effort, with hundreds of scientists from around the world joining forces to build this unique web-based tool, enabling the community to share and publish information that is critical for research but also for conservation purposes.

A new study published as the cover article for the April 2009 issue of The FASEB Journal (http://www.fasebj.org) promises to give physicians new ways to reduce deadly responses to viral infections of the brain and spinal cord. In the report, scientists from Columbia University, NY, detail for the first time the chemical processes that star-shaped nerve cells, called astrocytes, use to handle invading viruses and to summon other immune cells to cause life-threatening inflammation.

A study at the University of Leeds has shown, for the first time, that C. elegans worms crawl and swim using the same gait, overturning the widely accepted belief that these two behaviours are completely different.

Although perhaps the greatest public health achievement of the 20th century was the disinfection of water, a recent study now shows that the chemicals used to purify the water we drink and use in swimming pools react with organic material in the water yielding toxic consequences.

Attaching an antimicrobial drug, which is activated by light, to a peptide that binds to bacteria and stops them making toxins, produced a "magic bullet" that was highly effective at killing the superbug, methicillin-resistant Staphylococcus aureus (MRSA).
