Scientists at the CERN particle physics laboratory in Geneva noticed that the system’s carefully monitored temperatures were creeping up.
Further investigation into the failure of a cryogenic cooling plant revealed an unusual impediment. A piece of crusty bread had paralysed a high voltage installation that should have been powering the cooling unit.
Luckily, this isn't anything major, just a minor setback. But really, now small things like this will make the news. It means that they are on center stage and every little thing will get reported.
