Fermilab announced yesterday that they have evidence for the Higgs boson, and CERN is now announcing more convincing evidence for this particle. The Standard Model, the theory explaining our understanding of the fundamental particles and three of the forces of Nature (with the exception of gravity), predicts a field that is responsible for the mass of other particles. This is the Higgs field, which is 'carried' by a Higgs particle, which is the essence of modern quantum mechanics. This is a major confirmation of our understanding of Nature, which has been ongoing for decades since the prediction of the particle. Check out the video below.
