Science: Despite worldwide financial problems, representatives from the 20 nations involved in CERN, Europe’s particle-physics laboratory near Geneva, Switzerland, decided yesterday not to cancel any projects nor lay off any staff members; they will, however, seek to trim the budget by 6%. Three ways to cut costs were proposed by the CERN leadership: delay upgrades to current machines, shut down all eight accelerators in 2012 for repairs, and spend less on research and development for the proposed Compact Linear Collider, CLIC.
