Engineers operating the Large Hadron Collider (LHC) have smashed together proton beams in the machine for the very first time.More details at BBC News.
The step was described as a "great achievement" for those working on the huge physics experiment.
The low-energy collisions came after researchers circulated two beams simultaneously in the LHC's 27km-long tunnel earlier on Monday.
