Physics World, published by the Institute of Physics, has chosen the discovery of the Higgs boson and an experiment using the MINERvA detector at Fermilab as two of its top 10 breakthroughs of 2012.
A boson likely to be the Higgs was discovered by the ATLAS and CMS experiments at the LHC. Read media highlights on the Higgs discovery.
An experiment using the MINERvA detector, proposed by an engineer at North Carolina State University, successfully transmitted a message using neutrinos. You can read more about the experiment in this symmetry article.
