Using a technique that provides detailed images of nanoscale structures, researchers at the University of Michigan and Detroit's Henry Ford Hospital have discovered changes in the collagen component of bone that directly relate to bone health. http://www.physorg.com/news180721167.html Medicine & Health Tue, 22 Dec 2009 16:50:05 EST news180721167 From their humble beginnings as offshoots of the ordinary electric light bulb, particle accelerators have evolved in surprising directions. Among the most productive and promising developments have been light sources, first in the form of electron storage rings -- of which the Advanced Light Source is the world's premier source of soft x-rays -- and increasingly as versatile and sophisticated free electron lasers, the next generation of light sources now being studied at Berkeley Lab. http://www.physorg.com/news180718811.html Physics Tue, 22 Dec 2009 15:47:11 EST news180718811 (PhysOrg.com) -- New results by scientists at Umeľ University, Sweden, show that not only water but also alcohol solvents can be inserted to expand the structure of graphite oxide under high pressure conditions. The information is helpful in the search for new methods to develop amazing materials that could be used for instance in nanoelectronics and for energy storage. http://www.physorg.com/news180642806.html Nanotechnology Mon, 21 Dec 2009 18:42:23 EST news180642806 Exposing patients with chronic sinus disease to allergens and then obtaining repeated images by X-ray or ultrasound reveals that nasal allergies may be involved in some cases of chronic sinus disease, according to a report in the December issue of Archives of Otolaryngology-Head & Neck Surgery. http://www.physorg.com/news180638938.html Medicine & Health Mon, 21 Dec 2009 17:50:04 EST news180638938 (PhysOrg.com) -- Some of the most common minerals in biology, including those in bones and shells, have a mysterious structure: Their crystals are positioned in the same orientation, making them behave as one giant crystal, even though they do not look like a faceted crystal. http://www.physorg.com/news180631288.html Chemistry Mon, 21 Dec 2009 15:25:15 EST news180631288 (PhysOrg.com) -- As elements of the integrated circuits running our computers, phones and electronics, silicon wafers are everywhere. An ESA-led effort is establishing an out-of-this-world use for these commonplace items: when stacked together precisely by the thousand they promise to deliver astronomy?s clearest X-ray view yet of the most violent regions of space. http://www.physorg.com/news180626931.html Space & Earth Mon, 21 Dec 2009 14:09:29 EST news180626931 (PhysOrg.com) -- Scientists at the U.S. Department of Energy`s Brookhaven National Laboratory have found a new way to use a synthetic form of DNA to control the assembly of nanoparticles - this time resulting in switchable, three-dimensional and small-cluster structures that might be useful, for example, as biosensors, in solar cells, and as new materials for data storage. The work is described in Nature Nanotechnology, published online December 20, 2009. http://www.physorg.com/news180624054.html Nanotechnology Mon, 21 Dec 2009 13:21:26 EST news180624054 (AP) -- Web sites that buy original video clips often pay so little that "The Bannen Way," a flashy crime thriller debuting online, looked destined to be made poorly if it could be made at all. http://www.physorg.com/news180546696.html Technology Sun, 20 Dec 2009 16:11:16 EST news180546696 Dark spots on flower petals are common across many angiosperm plant families and occur on flowers such as some lilies, orchids, and daisies. Much research has been done on the physiological and behavioral mechanisms for how these spots attract pollinators. But have you ever wondered what these spots are composed of, how they develop, or how they only appear on some but not all of the ray florets? http://www.physorg.com/news180376920.html Biology Fri, 18 Dec 2009 16:43:21 EST news180376920 "T-rays" may make X-rays obsolete as a means of detecting bombs on terrorists or illegal drugs on traffickers, among other uses, contends a Texas A&M physicist who is helping lay the theoretical groundwork to make the concept a reality. In addition to being more revealing than X-rays in some situations, T-rays do not have the cumulative possible harmful effects. http://www.physorg.com/news180352656.html Physics Fri, 18 Dec 2009 10:30:01 EST news180352656 (PhysOrg.com) -- Intel has announced it will launch over two dozen new products next month, including new processors, chipsets, and a number of wireless components. http://www.physorg.com/news180341627.html Electronics Fri, 18 Dec 2009 08:30:01 EST news180341627 The Blu-ray Disc Association (BDA) today announced the finalization and release of the "Blu-ray 3DTM" specification. The specification, which represents the work of the leading Hollywood studios and consumer electronic and computer manufacturers, will enable the home entertainment industry to bring the 3D experience into consumers' living rooms on Blu-ray Disc, the most capable high definition home entertainment platform. http://www.physorg.com/news180302065.html Technology Thu, 17 Dec 2009 19:55:06 EST news180302065 (PhysOrg.com) -- A new carbon support that greatly increases the durability of proton-exchange membrane fuel cells has been developed by scientists at Pacific Northwest National Laboratory and Princeton University. This new material significantly improves the stability of the fuel cell catalyst and will potentially lower the cost of these fuel cells. This breakthrough research hit number one on the most-downloaded list of Electrochemistry Communications articles this fall. http://www.physorg.com/news180286762.html Nanotechnology Thu, 17 Dec 2009 15:40:06 EST news180286762 (PhysOrg.com) -- It's an unlikely place to build a NASA telescope: a leafy estate in Irvington, N.Y., that once belonged to the son of Alexander Hamilton. Inside a hangar-like building on the site, which is home to Columbia`s Nevis Laboratories for experimental physics, Charles Hailey is assembling mirrors for NuSTAR, the most sensitive X-ray telescope ever constructed. http://www.physorg.com/news180286322.html Space & Earth Thu, 17 Dec 2009 15:34:11 EST news180286322 The research that brought to light the fossils of Ardipithecus ramidus, a hominid species that lived 4.4 million years ago in what is now Ethiopia, has topped Science's list of this year's most significant scientific breakthroughs. The monumental find predates "Lucy," -- previously the most ancient partial skeleton of a hominid on record -- by more than one million years, and it inches researchers ever-closer to the last common ancestor shared by humans and chimpanzees. http://www.physorg.com/news180282874.html Other Sciences Thu, 17 Dec 2009 14:35:25 EST news180282874
