Scientists identify key roadblock to gene expression
A team of scientists has provided, for the first time, a detailed map of how the building blocks of chromosomes, the cellular structures that contain genes, are organized in the fruit fly Drosophila melanogaster. The work identifies a critical stop sign for transcription, the first step in gene expression, and has implications for understanding how the AIDS virus regulates its genes. The findings will be published in the 15 May 2008 issue of the journal Nature.

A safer alternative to aspirin?
A study in China has shown that the antiplatelet* drug cilostazol is as effective as aspirin at preventing recurrent stroke, but causes less bleeding events. The results suggest cilostazol could be a safer alternative to aspirin post-stroke for Chinese patients, and warrant both phase III trials and studies in other populations.

Global warming linked to caribou-calf mortality
Fewer caribou calves are being born and more of them are dying in West Greenland as a result of a warming climate, according to Eric Post, a Penn State associate professor of biology. Post, who believes that caribou may serve as an indicator species for climate changes including global warming, based his conclusions on data showing that the timing of peak food availability no longer corresponds to the timing of caribou births. The study, which was conducted in collaboration with Mads Forchhammer at the University of Aarhus in Denmark, will be published in the 12 July 2008 issue of the Philosophical Transactions of the Royal Society of London.
