When the Large Hadron Collider turns on next year, most physicists will be scouring the high-energy data for new particles such as the Higgs boson. Not Howard Georgi of Harvard University in the US, though -- he says he is on the look out for a new type of "stuff" altogether called "unparticles". If it exists, it would mean that our Standard Model of particle physics is not the whole story, and that things other than particles fill the universe (Phys. Rev. Lett. 98 221601).
