    breaking: New neutrino measurement finds particles obeying speed limit
    Scientists on the ICARUS experiment at Gran Sasso, Italy, announced today that they had found no evidence of superluminal neutrinos in a cross-check of earlier analysis from the OPERA experiment, also located at Gran Sasso.

    breaking: Daya Bay experiment makes key measurement, paves way for future discoveries
    An international collaboration of physicists working on a neutrino experiment in southern China announced today they have made a difficult measurement scientists have been chasing for more than a decade. The results of the Daya Bay neutrino experiment open an important window into understanding the behavior of neutrinos, and now the race is on to determine the implications. Two American experiments, one proposed and one under construction, seem well positioned to take the next steps.
