New and Improved [email protected] will Form the Backbone of Distributed Computing Network

[email protected] and BOINC are gradually converging, and the benefits for both are substantial. While [email protected] enjoys the increased flexibility of the BOINC platform, it brings to BOINC something of inestimable value to a distributed computing project: millions of [email protected] users, willing to use their computers' processing power for the advancement of scientific research.

Analyzing the Reobservations

[email protected] chief scientist Dan Werthimer and his team went back to Arecibo to reobserve the most promising candidate signals detected by the project so far. Unlike most of the year, when [email protected] piggy-backs on the regular operations of the telescope, this time the Werthimer's crew had the full use of the resources of the giant dish.

Scientists Detail Ambitious Goals of Mars Express

Scientists working on the European Space Agency's (ESA's) Mars Express detailed the mission's ambitious plan to study Mars from the top of its atmosphere to several kilometers beneath its surface, at a press conference in London, England last week.
