The world's highest-energy atom smasher, the Large Hadron Collider (LHC), will run at half its maximum energy through 2011 and not at all in 2012, officials at the European particle physics laboratory, CERN, announced last week. Curiously, though, physicists at the Fermi National Accelerator Laboratory did not immediately clamor to run their 27-year-old Tevatron collider for an extra year through 2012. That contrasts to last year, when in response to a delay to the LHC, Fermilab scientists pushed hard to run the Tevatron through 2011. This time, Fermilab physicists say an extra year's worth of data might not be worth the expense.
