Pop went the weasel and down went the Large Hadron Collider

GENEVA — It’s one of the physics world’s most complex machines, and it has been immobilized — temporarily — by a weasel.

Spokesman Arnaud Marsollier said the world’s largest atom smasher, the Large Hadron Collider at CERN outside Geneva, has suspended operations because a weasel invaded a transformer that helps power the machine and set off an electrical outage Friday.

Authorities say the incident was one of several small glitches that will delay plans to restart the $4.4 billion collider by a few days.

Marsollier said Friday the weasel died — and little remains of it.

Officials of the European Organization for Nuclear Research, known by its French acronym CERN, have been gearing up for new data from the 17-mile circuit that runs underground on the Swiss-French border.
