GENEVA — It’s one of the physics world’s most complex machines, and it has been immobilized — temporarily — by a weasel. Spokesman Arnaud Marsollier says the world’s largest atom smasher, the Large Hadron Collider at CERN has suspended operations because a weasel invaded a transformer that helps power the machine and set off an outage on Thursday night.
