Well, they have experimental evidence for the existence of a new bottomonium meson. That's a bottom and an antibottom quark pair for the uninitiated. The one they just found evidence for is so vanishingly small that it may as well be nothing. Not so much nothing as say a Neutrino which really is a rarefied piece of nothing but as the lowest energy state for a bottomonium meson its as close to noting whilst still being something as you can get. Now isn't that something!?!
