Electrons moving in graphene behave in an unusual way, as demonstrated by 2010 Nobel Prize laureates for physics Andre Geim and Konstantin Novoselov, who performed transport experiments on this one-carbon-atom-thick material. A review article, just published in EPJ B, explores the theoretical and experimental results to date of electrons tunneling through energy barriers in graphene. http://phys.org/news239893597.html Physics Mon, 07 Nov 2011 13:06:44 EST news239893597 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 Oh, yeah. Moving faster than the speed of light has been the hot topic in the news and OPERA has been the key player. In case you didn’t know, the experiment unleashed some particles at CERN, close to Geneva. It wasn’t the production that caused the buzz, it was the revelation they arrived at the Gran Sasso Laboratory in Italy around 60 nanoseconds sooner than they should have. Sooner than the speed of light allows! http://phys.org/news238050664.html Physics Mon, 17 Oct 2011 06:11:24 EST news238050664 The recent news of neutrinos moving faster than light might have got everyone thinking about warp drive and all that, but really there is no need to imagine something that can move faster than 300,000 kilometres a second. Indeed, the whole idea is illogical. http://phys.org/news237460906.html Physics Mon, 10 Oct 2011 10:21:58 EST news237460906 Using one of the most sensitive neutrino detectors on the planet, an international team including physicists Laura Cadonati and Andrea Pocar at the University of Massachusetts Amherst are now measuring the flow of solar neutrinos reaching earth more precisely than ever before. The detector probes matter at the most fundamental level and provides a powerful tool for directly observing the sun's composition. http://phys.org/news237204074.html Physics Fri, 07 Oct 2011 11:01:22 EST news237204074 (PhysOrg.com) -- It's been just two weeks since the Oscillation Project with Emulsion-tRacking Apparatus (OPERA) team released its announcement claiming that they have been measuring muon neutrinos moving faster than the speed of light, causing an uproar in the physics community. Since that time, many papers (perhaps as many as 30 to the preprint server arXiv alone) have been published seeking ways to discredit the findings. Thus far though, only two seem credible. http://phys.org/news237106952.html Physics Thu, 06 Oct 2011 08:10:11 EST news237106952 The recent news from the Oscillation Project with Emulsion-tRacking Apparatus (OPERA) neutrino experiment, that neutrinos have been clocked travelling faster than light, made the headlines over the last week – and rightly so. There are some very robust infrastructure and measurement devices involved that give the data a certain gravitas. http://phys.org/news236858319.html Physics Mon, 03 Oct 2011 10:58:48 EST news236858319 So far it is unknown which rules neutrinos follow when they alter their identity. A study in which scientists of the Excellence Cluster Universe at the Technische Universitaet Muenchen, Germany, participated has now revealed that even the last of the three parameters, which describe the oscillation of neutrinos is most likely to be greater than zero. This may help to understand the development of the early Universe. The paper will be published in the journal Physical Review D. http://phys.org/news234509081.html Physics Tue, 06 Sep 2011 06:24:55 EST news234509081 (PhysOrg.com) -- The physics community got a jolt last year when results showed for the first time that neutrinos and their antimatter counterparts, antineutrinos, might be the odd man out in the particle world and have different masses. This idea was something that went against most commonly accepted theories of how the subatomic world works. http://phys.org/news233496483.html Physics Thu, 25 Aug 2011 13:08:33 EST news233496483 The Daya Bay Reactor Neutrino Experiment has begun its quest to answer some of the most puzzling questions about the elusive elementary particles known as neutrinos. The experiment’s first completed set of twin detectors is now recording interactions of antineutrinos (antipartners of neutrinos) as they travel away from the powerful reactors of the China Guangdong Nuclear Power Group in southern China. http://phys.org/news232616980.html Physics Mon, 15 Aug 2011 08:49:54 EST news232616980 Nearly half of the Earth's heat comes from the radioactive decay of materials inside, according to a large international research collaboration that includes a Kansas State University physicist. http://phys.org/news231506652.html Space & Earth Tue, 02 Aug 2011 13:00:44 EST news231506652 Hundreds of physicists from around the world are making plans to shoot the world's most intense beam of neutrinos from Illinois, underground through Iowa, all the way to a former gold mine in South Dakota. And Iowa State University's Mayly Sanchez is part of the research team. http://phys.org/news230199255.html Physics Mon, 18 Jul 2011 09:14:33 EST news230199255 Scientists of the MINOS experiment at the Department of Energy's Fermi National Accelerator Laboratory announced today (June 24) the results from a search for a rare phenomenon, the transformation of muon neutrinos into electron neutrinos. The result is consistent with and significantly constrains a measurement reported 10 days ago by the Japanese T2K experiment, which announced an indication of this type of transformation. http://phys.org/news228155249.html Physics Fri, 24 Jun 2011 17:28:55 EST news228155249 By shooting a beam of neutrinos through a small slice of the Earth under Japan, physicists say they've caught the particles changing their stripes in new ways. These observations may one day help explain why the universe is made of matter rather than anti-matter. http://phys.org/news227353614.html Physics Wed, 15 Jun 2011 10:47:09 EST news227353614 (PhysOrg.com) -- Where did all the matter in the universe come from? This is one of the biggest mysteries in fundamental physics and exciting results released on 15 June 2011 from the international T2K neutrino experiment in Japan could be an important step towards resolving this puzzle. http://phys.org/news227347108.html Physics Wed, 15 Jun 2011 08:58:53 EST news227347108 Like the billions of tiny neutrinos that zip through the Earth every second, scientific exchanges will be flying thick and fast in Madison. http://phys.org/news223205720.html Physics Thu, 28 Apr 2011 10:35:59 EST news223205720 (PhysOrg.com) -- Physicist Nathan Whitehorn and a team of researchers with the IceCube collaboration have failed to come up with evidence to prove that neutrinos come from, or are caused by, gamma ray bursts, (cosmic explosions) after a year of study. http://phys.org/news222084262.html Physics Fri, 15 Apr 2011 11:40:01 EST news222084262 (PhysOrg.com) -- If the latest theory of Tom Weiler and Chui Man Ho is right, the Large Hadron Collider – the world's largest atom smasher that started regular operation last year – could be the first machine capable causing matter to travel backwards in time. http://phys.org/news219425928.html Physics Tue, 15 Mar 2011 16:40:01 EST news219425928 As part of a global physics project, a team of Kansas State University physics researchers is starting small. http://phys.org/news217167270.html Physics Thu, 17 Feb 2011 12:14:56 EST news217167270 Berkeley Lab physicists and engineers are among the leaders of the unique Daya Bay Reactor Neutrino Experiment, where Chinese and American scientists, with colleagues from Russia, Taiwan, and the Czech Republic, have come together to investigate a peculiar phenomenon related to so-called neutrino mixing. Kam-Biu Luk of Berkeley Lab’s Physics Division is Daya Bay’s scientific co-spokesperson, with Yifang Wang of Beijing’s Institute of High Energy Physics. Bill Edwards of the Lab’s Physics Division is the U.S. Project and Operations Manager. http://phys.org/news217060819.html Physics Wed, 16 Feb 2011 06:40:37 EST news217060819 (PhysOrg.com) -- The Double Chooz collaboration recently completed its neutrino detector which will see anti-neutrinos coming from the Chooz nuclear power plant in the French Ardennes. The experiment is now ready to start collecting data in order to measure fundamental neutrino properties with important consequences for particle and astro-particle physics. http://phys.org/news215282820.html Physics Wed, 26 Jan 2011 16:47:57 EST news215282820 An extraordinary underground observatory for subatomic particles has been completed in a huge cube of ice one kilometre on each side deep under the South Pole, researchers said. http://phys.org/news212337965.html Physics Thu, 23 Dec 2010 14:46:18 EST news212337965 (PhysOrg.com) -- On Saturday, December 18, the IceCube Neutrino Observatory sank the last of 86 strings of sensitive photodetectors to a depth of almost two and a half kilometers in the ice at the South Pole, marking completion of the huge neutrino telescope. http://phys.org/news212054009.html Physics Mon, 20 Dec 2010 07:53:58 EST news212054009 Researchers from the Institute for Corpuscular Physics (IFIC) and other European groups have studied the effects of the presence of dark matter in the Sun. According to their calculations, low mass dark matter particles could be transferring energy from the core to the external parts of the Sun, which would affect the quantity of neutrinos that reach the Earth. http://phys.org/news210427701.html Physics Wed, 01 Dec 2010 12:08:39 EST news210427701 (PhysOrg.com) -- Seeking to detect mysterious, ultra-high-energy neutrinos from distant regions of space, a team of astronomers used the Moon as part of an innovative telescope system for the search. Their work gave new insight on the possible origin of the elusive subatomic particles and points the way to opening a new view of the Universe in the future. http://phys.org/news210356391.html Physics Tue, 30 Nov 2010 16:20:12 EST news210356391 The National Science Foundation has signed a five-year, $34.5-million agreement with the University of Wisconsin-Madison to operate a unique telescope--a cubic kilometer in volume--buried in the Antarctic ice sheet between 1,400 meters and 2,400 meters deep. http://phys.org/news209726186.html Physics Tue, 23 Nov 2010 09:16:45 EST news209726186 (PhysOrg.com) -- The results of a high-profile Fermilab physics experiment involving a University of Michigan professor appear to confirm strange 20-year-old findings that poke holes in the standard model, suggesting the existence of a new elementary particle: a fourth flavor of neutrino. http://phys.org/news207896570.html Physics Tue, 02 Nov 2010 06:03:12 EST news207896570 There's nothing like temperatures that can reach minus 100 degrees Fahrenheit to keep you on your toes. http://phys.org/news207390910.html Physics Wed, 27 Oct 2010 09:35:34 EST news207390910 In December 2010, IceCube -- the world's first kilometer-scale neutrino observatory, which is located beneath the Antarctic ice -- will finally be completed after two decades of planning. In an article in the AIP's Review of Scientific Instruments, Francis Halzen, the principal investigator of the IceCube project, and his colleague Spencer Klein of Lawrence Berkeley National Laboratory provide a comprehensive description of the observatory, its instrumentation, and its scientific mission -- including its most publicized goal: finding the sources of cosmic rays. http://phys.org/news202483133.html Physics Tue, 31 Aug 2010 14:19:19 EST news202483133 (PhysOrg.com) -- Astronomers using ESO’s Very Large Telescope have for the first time obtained a three-dimensional view of the distribution of the innermost material expelled by a recently exploded star. The original blast was not only powerful, according to the new results. It was also more concentrated in one particular direction. This is a strong indication that the supernova must have been very turbulent, supporting the most recent computer models. http://phys.org/news200127668.html Space & Earth Wed, 04 Aug 2010 08:40:01 EST news200127668
