Science: An unexpected abundance of high-energy electrons from space could be evidence of particles of dark matter--the weighty and mysterious stuff whose gravity holds the galaxies together. But if the sightings really do point to dark matter, then physicists may have to revise their ideas about what the stuff is.
Excess particles from space may hint at dark matter

This reported predictive success of the Standard Model shows what a marvelous achievement the Standard Model is. If the LHC of CERN discovers the Higgs Boson, this would put the standard model on all the more stable footing.
There still remains the possibility that quarks, and perhaps even leptons have a sub-structure or sub-composition that is not excited at the level of ordinary QCD physics.
