FILE - This 2011 image provide by CERN, shows a real CMS proton-proton collision in which four high energy electrons (green lines and red towers) are observed in a 2011 event. The event shows characteristics expected from the decay of a Higgs boson but is also consistent with background Standard Model physics processes. Physicists in Italy said Wednesday, March 6, 2013 they are closer to concluding that what they found last year was the elusive "God particle." But they still haven't reached that "Eureka moment" when they can announce the Higgs boson is found. The long theorized subatomic particle would explain why matter has mass and has been called a missing cornerstone of physics. Large Hadron Collider (LHC) -- where protons zip at near light-speed around the 17-mile-long (27 kilometer) underground ring beneath Switzerland and France -- physicists say the particle is the Higgs. In Photos: Searching for the Higgs Boson "The preliminary results with the full 2012 data set are magnificent and to me it is clear that we are dealing with a Higgs boson though we still have a long way to go to know what kind of Higgs boson it is," said CMS spokesperson Joe Incandela in a statement. Dave Charlton, ATLAS spokesperson agreed, the new results "point to the new particle having the spin-parity of a Higgs boson as in the Standard Model," referring to a quantum property of elementary particles. To confirm the particle as the Higgs boson, physicists needed to collect tons of data that would reveal its quantum properties as well as how it interacted with other particles. For instance, a Higgs particle should have no spin and its parity, or the measure of how its mirror image behaves, should be positive, both of which were supported by data from the ATLAS and CMS experiments. Even so, the scientists are not sure whether this Higgs boson is the one predicted by the Standard Model or perhaps the lightest of several bosons predicted to exist by other theories. Seeing how this particle decays into other particles could let physicists know whether this Higgs is the "plain vanilla" Standard Model Higgs. Detecting a Higgs boson is rare, with just one observed for every 1 trillion proton-proton collisions. As such, the LHC physicists say they need much more data to understand all of the ways in which the Higgs decays. Its mass of 126 times the mass of the proton is just about what would be needed to create a fundamentally unstable universe that would lead to a cataclysm billions of years from now. "It may be the universe we live in is inherently unstable, and at some point billions of years from now it's all going to get wiped out," added Lykken, a collaborator on the CMS experiment.

Federer and Nadal to meet in last eight By Mark Lamport-Stokes INDIAN WELLS, California (Reuters) - Defending champion Roger Federer and Rafa Nadal set up a mouth-watering showdown in the BNP Paribas quarter-finals after they battled through tricky fourth-round encounters on Wednesday. Federer rode his luck to scrape past fellow Swiss Stanislas Wawrinka 6-3 6-7 7-5 while Nadal had to come from a set down to beat talented Latvian qualifier Ernests Gulbis 4-6 6-4 7-5. Italian bishops thank God for wrong pope VATICAN CITY (Reuters) - Italian bishops were so convinced that one of their own would become pope that they sent a congratulatory message to the media thanking God for the election of a prelate from Milan. The trouble was, the new pope had already been named as Argentinian cardinal Jorge Bergoglio. The secretary-general of the Italian conference, Monsignor Mariano Crociata, expressed "joy and thanks" to God for the election of Cardinal Angelo Scola of Milan in a statement sent to reporters at 8:23 pm (3:23 pm ET) on Wednesday night. Soccer-Messi and Barca make a mockery of the doubters By Iain Rogers BARCELONA, March 13 (Reuters) - Lionel Messi's Barcelona gave an emphatic response to the doubters when they made Champions League history by overturning a 2-0 first-leg deficit to oust seven-times European Cup winners AC Milan on Tuesday. Messi's superb double set Barca on their way in the first half at a raucous but desperately tense Nou Camp and David Villa and Jordi Alba struck after the break to send the La Liga side through to the quarter-finals 4-2 on aggregate. Wife Can't Forgive Husband Who Cheated On Her For Years DEAR ABBY: I have been married 30 years and have raised four children to adulthood. I recently found out my husband has been having an affair with a prostitute from a strip club. He paid all her living expenses and promised to marry her. He told her his wife had run away with another man and that he was divorced. He wants to continue living together and pretend nothing happened. Then he went to a psychiatrist, who diagnosed him with a "mixed personality disorder.
