Physicists rejoiced this week at the successful test of their massive new particle accelerator, the Large Hadron Collider, near Geneva, Switzerland. But some 450 kilometers south-east - and making a lot less of a hullabaloo about things — another major physics experiment is working to recover from a debilitating accident. The Virgo gravity-wave interferometer, an $114 million experiment located outside of Pisa, Italy, has been incapacitated by a vacuum failure for most of the summer. (source: nature.com)
