Back in my youth, when every other weekend seemed to bring a new particle yet unexplained - this was before the standard model, before the quark, and even before the eight-fold way - particle physics seemed a vast unexplored jungle. Today's particle physics, by comparison, seems unbearably humdrum, with nearly every tree and bush mapped to the millimeter and promised discoveries always being pushed to the next horizon.
Maybe the field isn't quite dead yet. Lumo brings word of a new effect that might be significant. A hint of a new particle?
