Here I'm starting this thread to share recent developments,discoveries, inventions and research in field of Science.I hope it will keep you "up-to- date".
GENEVA: International scientists said on Tuesday they had found signs of the Higgs boson, an elementary sub-atomic particle believed to have played a vital role in the creation of the universe after the Big Bang. Peter Higgs, the 82-year-old British theoretical physicist who first proposed the existence of the particle in 1964 as the missing link of a grand theory of matter and energy, was watching the announcement on a webcast with colleagues at Edinburgh University, where he is an emeritus professor. "I won't be going home to open a bottle of whisky to drown my sorrows, but on the other hand I won't be going home to open a bottle of champagne either," his colleague Alan Walker quoted him as saying after the announcement. The leaders of two experiments, Atlas and CMS, revealed their findings to a packed seminar at the CERN physics research centre near Geneva, where they have tried to find traces of the elusive boson by smashing particles together at near light-speed in the Large Hadron Collider. The experiments generated such excitement by independently reaching very similar conclusions. But the scientists were quick to warn that their results have not yet reached the level of certainty that would let them claim a discovery -- hence Higgs's caution. Under what is known as the Standard Model of Physics, the boson is posited to have been the agent that gave mass and energy to matter after the creation of the universe 13.7 billion years ago - leading some to nickname it the "God particle". Its discovery would fill the last remaining hole in the model. However, that does not mean it must exist, and some eminent physicists such as Stephen Hawking believe it does not. "If the Higgs observation is confirmed ... this really will be one of the discoveries of the century," said Themis Bowcock, professor of particle physics at Britain's Liverpool University. "Physicists will have uncovered a keystone in the makeup of the universe ... whose influence we see and feel every day of our lives." BIG BANG CONDITIONS The Large Hadron Collider at CERN, a vast underground particle accelerator that costs 200,000 Swiss francs an hour to run, is designed to recreate the conditions of the Big Bang to allow particles such as the Higgs boson to be found and studied. While the boson's discovery would cement current knowledge about particles such as electrons and photons, proof that it does not exist would undermine the foundations of accepted theories of the make-up of the universe. The particle is so short-lived that it can only be detected from the particles that it decays into. In the course of millions of collisions, the scientists are hunting for a significant excess of a particular combination of decay particles. Although they are now converging on a particular profile for the Higgs, they will need another year's worth of such collisions to rule out a statistical fluke. "The window for the Higgs mass gets smaller and smaller," said CERN Director General Rolf Heuer. "But please be prudent. Remember, we have not found it yet, nor have we excluded it yet. There is still Higgs hunting to be done." Oliver Buchmueller, senior physicist on the CMS experiment, said: "It can still happen that it is a fluctuation, but all we see from both experiments is compatible with what we would expect for a Higgs signal to build up... "But we really need the data from next year to be sure of what we're seeing." Claire Shepherd-Themistocleus, head of the CMS Group at the STFC Rutherford Appleton Laboratory, said: "We are homing in on the Higgs ... "We have had hints today of what its mass might be and the excitement of scientists is palpable. Whether this is ultimately confirmed or we finally rule out a low-mass Higgs boson, we are on the verge of a major change in our understanding of the fundamental nature of matter."

Ofcourse we can believe because we got this news from a reliable source.The scientists always talk about facts so they are reliable.

Need simple answer regarding higgs bosson particles
Can anybody explain in simple words what are higgs bossons particles, as reading many times about it, my concept is not clear yet.

It is an elusive subatomic particle that, if found, would confirm a long-held understanding about why matter has mass and how the universe’s fundamental building blocks behave. The ideas behind the search of Higgs Boson date back to 1960s when a British physicist named Peter Higgs hypothesized that the existence of this particle in matter is well within the realms of possibility and it explains why the fundamental particles in matter have mass. Those particles, such as electrons, are the building blocks of the universe. Mass is a trait that combines with gravity to give an object weight. It is so named because it was hypothesized by the scientist Peter Higgs some 40 years ago.

If it true then How objects interact with higgs field which gives some objects greater and lesser mass? . if this hypothesis failed then why every object will be mass less? |

Replying to your second question, the scientists believe they are just round the corner to conclude that Higgs Boson actually exist. They are sure to make this groundbreaking discovery by the next year or sooner than that. Whether the theory fails to prove, yet remains to be seen. The same can be better understood with the help of the video given below. What is a Higgs Boson? - YouTube
