if they are lucky, they will get to hear from the elusive higgs boson, too. >> this higgs boson -- this is probably the most exciting meaning in the league -- the last decade at least. now we have the game running. it is a tremendous jump. >> the nhc is a ring buried underground near the swiss border with geneva. it takes subatomic particles, called hadrons, and this case protons, and smashes them together. the collisions result in energy and a shower of smaller particles. one of which it just might be a higgs boson. the physicist and in paris care so much about the higgs boson because it is part of an elegant theory that explains why everything around us has mass. without it, the standard model for how particles interact would need a radical rethink. >> it is an new frontier. what we are seeing is house subatomic particles be paid -- halt subatomic particles be paid. -- how subatomic particles behave. it is very difficult to understand and calibrate. these results are calibrated 9 extent so well that we can actually generate interesting science so well. which is actually quite a big li

collisions recorded then the other collider, and this gives us an excellent chance to find the higgs boson. >> researchers from the large hadron collider have revealed these pictures which shows subatomic particles that are already known to science. soon they will find completely new ones. despite delays in early problems, the europeans are catching up fast with their american rivals. >>> archbishop desmond tutu has announced he is withdrawing from public life. the nobel peace prize winner led the campaign against the apartheid regime in south africa and has continued fighting injustice across the world. >> one of the world's great personalities, desmond tutu announced his retirement in his own irrepressible style. >> the time has come to slow down, to have tea with my beloved wife in the afternoon, to watch rugby and soccer and tennis, to travel, to visit my children and grandchildren. >> the archbishop turns 79 in october. from then on, he will restrict his public appearances and withdraw from some of the many organizations which he represents. south africa will miss him. under his leade
