Physicists of the Double Chooz experiment detected a short-range disappearance of electron antineutrinos. They presented this result on Wednesday 9 November 2011 at the LowNu conference in Seoul, Korea. It helps determine the so-far unknown third neutrino mixing angle which is a fundamental property with important consequences for particle and astro-particle physics. The Double Chooz experiment is looking for neutrinos produced in the nearby nuclear power plant. A measurement of this third angle would complete our picture of neutrino oscillations as reported by other experiments and will open new perspectives in understanding why we find matter and no antimatter in our today's Universe. http://phys.org/news240050747.html Physics Wed, 09 Nov 2011 08:45:55 EST news240050747 An international team of scientists using NASA's Fermi Gamma-ray Space Telescope has discovered a surprisingly powerful millisecond pulsar that challenges existing theories about how these objects form. http://phys.org/news239619708.html Space & Earth Fri, 04 Nov 2011 10:02:03 EST news239619708 Scientists who threw down the gauntlet to physics by reporting particles that broke the Universe's speed limit said on Friday they were revisiting their contested experiment. http://phys.org/news239009787.html Physics Fri, 28 Oct 2011 08:36:39 EST news239009787 Astrophysicists have found evidence of black holes destroying stars, a long-sought phenomenon that provides a new window into general relativity.

Now, Japanese scientists at RIKEN, as part of a collaborative team with researchers from Denmark, Japan, the United Kingdom and Hungary, have shown that antiprotons—particles with the same mass as a proton but negatively charged—collide with molecules in a very different way from their interaction with atoms. The result sets an important benchmark for testing future atomic-collision theories. http://phys.org/news212407510.html Physics Fri, 24 Dec 2010 10:05:55 EST news212407510 Physicists at the University of British Columbia and TRIUMF have proposed a unified explanation for dark matter and the so-called baryon asymmetry -- the apparent imbalance of matter with positive baryon charge and antimatter with negative baryon charge in the Universe. http://phys.org/news210249799.html Physics Mon, 29 Nov 2010 10:43:36 EST news210249799 The ATLAS collaboration at CERN today officially unveiled a giant mural depicting the ATLAS particle detector, which is currently collecting data at world's most powerful particle accelerator, the Large Hadron Collider. Installed in a cavern 100 metres underground, the ATLAS detector is no longer open for visits.

The mural is designed to be the next best thing to seeing the detector itself. http://phys.org/news205661009.html Other Sciences Thu, 07 Oct 2010 09:04:39 EST news205661009 At the Large Hadron Collider at CERN protons crash into each other at incredibly high energies in order to 'smash' the protons and to study the elementary particles of nature - including quarks. Quarks are found in each proton and are bound together by forces which cause all other known forces of nature to fade. To understand the effects of these strong forces between the quarks is one of the greatest challenges in modern particle physics. New theoretical results from the Niels Bohr Institute show that enormous quantities of random numbers can describe the way in which quarks ’swing’ inside the protons. The results have been published in arXiv and will be published in the journal Physical Review Letters. http://phys.org/news204809213.html Physics Mon, 27 Sep 2010 12:27:18 EST news204809213 (PhysOrg.com) -- Researchers describe how to carry out the first experimental test of string theory in a paper published tomorrow in Physical Review Letters. http://phys.org/news202553083.html Physics Wed, 01 Sep 2010 09:45:07 EST news202553083 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. http://phys.org/news200742616.html Physics Wed, 11 Aug 2010 10:50:34 EST news200742616 A team of researchers from the Stanford Institute of Materials and Energy Science, a joint institute of the Department of Energy's SLAC National Accelerator Laboratory and Stanford University, and their international collaborators have pushed research into topological insulators not just one, but two steps forward. http://phys.org/news200674878.html Physics Tue, 10 Aug 2010 16:21:57 EST news200674878 First results from the LHC at CERN are being revealed at ICHEP, the world's largest international conference on particle physics, which has attracted more than 1000 participants to its venue in Paris.
