The Large Hadron Collider started working again at CERN this morning for the first time in eighteen months.  You can follow the full coverage here, live from CERN.  The Guardian is putting out an edited version, here.  Not all live events are interesting, certainly not the same ones for everyone;  I prefer this to live sports coverage.  Is there a Small Hadron Collider?  Trond and Canahan report, below.
