In Yesterday's issue of the journal Science physicist report they have
measured the mass of the W-Boson, a mediator of the week nuclear force, to
within 0.01%, by far the most accurate ever made, and they found it
differed from the theoretical prediction the standard model says it should
have by 7 standard deviations, only 5 are needed to claim a discovery. If
the experimentalists have not made some systematic error in their
measurements, and currently there's no evidence they have, then this is
wonderful , the first hint  of physics beyond the standard model.
