Signals from a particle collider near Geneva suggested in September that scientists might have sighted a long-sought particle thought to be the source of mass itself. Those hints of the so-called Higgs boson were enough to postpone the permanent shut-down of the 11-year-old Large Electron Positron (LEP) collider until Nov. 2 (SN: 9/23/00, p. 196: Most-Wanted Particle Appears, Perhaps). A new hint of the Higgs has cropped up in that extended run.
