In a battle between a rodent and a 17-mile-long superconducting machine designed to smash protons, one might expect the rodent to fare poorly. And in this case, it did, though not without the little guy doing some damage of its own.
From a BBC report:
The Large Hadron Collider particle accelerator at Cern is offline after a short circuit – caused by a weasel.
The unfortunate creature did not survive the encounter with a high-voltage transformer at the site near Geneva in Switzerland.
The LHC was running when a “severe electrical perturbation” occurred in the early hours of Friday morning.
