(PhysOrg.com) -- A thin rain of charged particles continually bombards our atmosphere from outer space. The mysterious particles were first detected 100 years ago but until 10 years ago when a new type of telescope began to come online physicists weren't sure where the "cosmic rays" came from or how they were generated. They suspected the particles were accelerated by supernova shockwaves, but suspicions aren't proof. http://www.physorg.com/news179427195.html Space & Earth Mon, 07 Dec 2009 18:30:01 EST news179427195 Before one of your muscles can twitch, before the thought telling it to flex can race down your nerve, a tiny floodgate of sorts -- called an ion channel -- must open in the surface of each cell in these organs to let in the chemical signals that spur the cell to action. New research at the National Institute of Standards and Technology has allowed scientists to observe ion channels within the surface membrane for the first time, potentially offering insights for future drug development. http://www.physorg.com/news178979870.html Chemistry Wed, 02 Dec 2009 12:38:21 EST news178979870 As the nation ponders its energy choices, Americans keep asking themselves: how can the country make better use of its resources and emit fewer greenhouse gases without hurting U.S. industries? A research project at Idaho National Laboratory may have part of the answer. http://www.physorg.com/news178821091.html Technology Mon, 30 Nov 2009 17:10:01 EST news178821091 Super Earths are named for their size, but these planets - which range from about 2 to 10 Earth masses - could be superior to the Earth when it comes to sustaining life. They could also provide an answer to the ‘Fermi Paradox`: Why haven`t we been visited by aliens? http://www.physorg.com/news178821471.html Space & Earth Mon, 30 Nov 2009 16:38:28 EST news178821471 The concept of confinement is one of the central ideas in modern physics. The most famous example is that of quarks which bind together to form protons and neutrons. Now Prof. Bella Lake from Helmholtz-Zentrum Berlin (Germany) together with an international team of scientists report for the first time an experimental realization and a proof of confinement phenomenon observed in a condensed matter system. http://www.physorg.com/news178724926.html Physics Sun, 29 Nov 2009 13:49:37 EST news178724926 (PhysOrg.com) -- NASA's Fermi Gamma-ray Space Telescope has made the first unambiguous detection of high-energy gamma-rays from an enigmatic binary system known as Cygnus X-3. The system pairs a hot, massive star with a compact object -- either a neutron star or a black hole -- that blasts twin radio-emitting jets of matter into space at more than half the speed of light. http://www.physorg.com/news178547547.html Space & Earth Fri, 27 Nov 2009 12:34:14 EST news178547547 (PhysOrg.com) -- A star's spectacular death in the constellation Taurus was observed on Earth as the supernova of 1054 A.D. http://www.physorg.com/news178220365.html Space & Earth Mon, 23 Nov 2009 17:40:06 EST news178220365 (PhysOrg.com) -- Much of our planet's mineral wealth was deposited billions of years ago when Earth's chemical cycles were different from today's. Using geochemical clues from rocks nearly 3 billion years old, a group of scientists including Andrey Bekker and Doug Rumble from the Carnegie Institution have made the surprising discovery that the creation of economically important nickel ore deposits was linked to sulfur in the ancient oxygen-poor atmosphere. http://www.physorg.com/news177863954.html Space & Earth Thu, 19 Nov 2009 15:30:01 EST news177863954 A recent experiment at the DOE's Thomas Jefferson National Accelerator Facility has found that a proton's nearest neighbors in the nucleus of the atom may modify the proton's internal structure. http://www.physorg.com/news177787801.html Physics Wed, 18 Nov 2009 17:31:37 EST news177787801 (PhysOrg.com) -- Idaho National Laboratory scientists have set a new world record with next-generation particle fuel for use in high temperature gas reactors (HTGRs). http://www.physorg.com/news177678729.html Technology Tue, 17 Nov 2009 12:00:02 EST news177678729 (PhysOrg.com) -- Astrophysicists at the University of Warwick and Kiel University have discovered two earth sized bodies with oxygen rich atmospheres - however there is a bit of a disappointing snag for anyone looking for a potential home for alien life, or even a future home for ourselves, as they are not planets but are actually two unusual white dwarf stars. http://www.physorg.com/news177258394.html Space & Earth Thu, 12 Nov 2009 14:27:33 EST news177258394 In an advance that could help ease health and environmental concerns about the emerging nanotechnology industry, scientists are reporting development of technology for changing the behavior of nanoparticles in municipal sewage treatment plants - their main gateway into the environment. Their study will be published online November 12 in ACS' journal Environmental Science & Technology. http://www.physorg.com/news177242892.html Space & Earth Thu, 12 Nov 2009 10:09:08 EST news177242892 (PhysOrg.com) -- Evidence for a thin veil of carbon has been found on the neutron star in the Cassiopeia A supernova remnant. This discovery, made with NASA's Chandra X-ray Observatory, resolves a ten-year mystery surrounding this object. http://www.physorg.com/news176567767.html Space & Earth Wed, 04 Nov 2009 14:37:05 EST news176567767 (PhysOrg.com) -- Research by Michigan State University scientists has shed new light on the properties of neutron stars, galactic oddities that are formed when a large star runs out of fuel and collapses. http://www.physorg.com/news176409161.html Physics Mon, 02 Nov 2009 18:33:35 EST news176409161 A team of researchers led by a Case Western Reserve University physicist is planning the world's largest, most sensitive experiment to catch the stuff of dark matter, stuff that's proved way beyond invisible. http://www.physorg.com/news176041529.html Physics Thu, 29 Oct 2009 14:10:02 EST news176041529
