The scientists at the European Organization for Nuclear Research (CERN) have been unsuccessful in proving the existence of the so-called "God particle" so far, but they are getting close, according to various media reports on Monday. According to AFP reporter Marlowe Hood, experiments at the Large Hadron Collider (LHC), located at the CERN headquarters in Geneva, Switzerland, have yet to discover the Higgs boson, a sub-atomic particle believed to have played an important role in the creation...

Physicists working at the University of California, Santa Barbara and the University of Konstanz in Germany have developed a breakthrough in the use of diamond in quantum physics, marking an important step toward quantum computing. The results are reported in this week's online edition of Nature Physics. The physicists were able to coax the fragile quantum information contained within a single electron in diamond to move into an adjacent single nitrogen nucleus, and then back again using...

The long, slow decay of carbon-14 allows archaeologists to accurately date the relics of history back to 60,000 years. And while the carbon dating technique is well known and understood (the ratio of carbon-14 to other carbon isotopes is measured to determine the age of objects containing the remnants of any living thing), the reason for carbon-14's slow decay has not been understood. Why, exactly, does carbon-14 have a half-life of nearly 6,000 years while other light atomic nuclei have...

The antimatter equivalent of helium nuclei has been produced by an international team of physicists working with the Relativistic Heavy Ion Collider at the U.S. Department of Energy's Brookhaven National Laboratory in New York. Two University of California, Davis professors are members of the team. A paper describing their results is published online this week by the journal Nature. "This is the heaviest antimatter anyone has ever created," said Manuel Calderon de la Barca Sanchez, professor...

Physicists study rare particles to learn why the universe has more matter than antimatter Using data from experiments performed in 2010 at the Large Hadron Collider (LHC), the world's largest particle accelerator near Geneva, Switzerland, scientists are studying rare particle decays that could explain why the universe has more matter than antimatter. Led by Sheldon Stone, a physicist at Syracuse University, a group of scientists recently published their first observations of two different...

Ground-breaking experiments in Switzerland question Universe's building blocks Researchers used Einstein's famous E=mc2 equation and the Large Hadron Collider to recreate a miniature version of the event at the origins of our Universe, and the first findings from their work were published in the journal Physical Review Letters. Dr. Andreas Warburton of McGill's Department of Physics made leading contributions to the analysis of data from the experiment, known as "ATLAS," meaning the findings...

This month physicist Juan Collar and his associates are taking their attempt to unmask the secret identity of dark matter into a Canadian mine more than a mile underground. The team is deploying a 4-kilogram bubble chamber at SNOLab, which is part of the Sudbury Neutrino Observatory in Ontario, Canada. A second 60-kilogram chamber will follow later this year. Scientists anticipate that dark matter particles will leave bubbles in their tracks when passing through the liquid in one of these...

New constraints on the elusive Higgs particle are more stringent than ever before. Scientists of the CDF and DZero collider experiments at the U.S. Department of Energy's Fermilab revealed their latest Higgs search results Monday July 26 at the International Conference on High Energy Physics, held in Paris from July 22-28. Their results rule out a significant fraction of the allowed mass range established by earlier experiments. The Fermilab experiments now exclude a Higgs particle with a...

The Large Hadron Collider (LHC) is giving physicists hopeful candidates in the hunt for the heaviest elementary particle known to science. According to BBC News, so far their observations have been leading them in that direction. If the observations can be confirmed, it would be a first for Europe as the top quark particle has only been generated in one lab in the US. Dr Arnaud Lucotte, from the French National Centre of Scientific Research (CNRS), said the discovery could help physicists...

Study refines predictions of what may constitute evidence of elusive particles Astrophysicists are looking everywhere "“ inside the Large Hadron Collider, in deep mines and far out into space "“ for evidence of dark matter, which makes up about 25 percent of the energy density of the universe. Despite the recent tantalizing observation of excess high-energy positrons "“ thought to be due to dark matter "“ UC Irvine researchers say we're not quite there yet. Models...


Word of the Day
toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
