Physicists have spent much time searching fruitlessly for magnetic monopoles, the magnetic equivalent of the fundamental bits of electric charge carried by electrons; now they have used the world's highest energy accelerator and once again come up empty. This nondiscovery, now in press at Physical Review Letters, puts some new limits on the mass of this aspiring particle and has also sparked a bit of a debate about how to look for it.
