Over the weekend, Cern ran particle beams through the Large Hadron Collider for the first time since it was shut down last September. After a helium leak caused magnets to overheat, operations at the LHC were suspended for cleanup and repairs. After tests on October 23 and 25, scientists hope to have the LHC running again in full by November.
