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 Communication between nerve cells is vital for our bodies to function. Part of this communication happens through vesicles containing signalling molecules called neurotransmitters. The vesicle fuses with the nerve cell membrane; the neurotransmitters are released and quickly recorded by the next nerve cell. It is crucial that new vesicles constantly are produced for the nerve cell communication continuously to take place. If parts of this communication do not work, it leads to nerve pain like phantom pain following amputation. http://www.physorg.com/news180713035.html Medicine & Health Tue, 22 Dec 2009 14:30:07 EST news180713035 (PhysOrg.com) -- Physicists theorize that quantum phenomena could provide a major boost to batteries, with the potential to increase energy density up to 10 times that of lithium ion batteries. According to a new proposal, billions of nanoscale capacitors could take advantage of quantum effects to overcome electric arcing, an electrical breakdown phenomenon which limits the amount of charge that conventional capacitors can store. http://www.physorg.com/news180704455.html Physics Tue, 22 Dec 2009 11:42:13 EST news180704455 (PhysOrg.com) -- Cornell researchers are devising methods to detect the magnetic fields of individual electrons and atomic nuclei, which they hope to use to make a nanoscale version of magnetic resonance imaging. http://www.physorg.com/news180680263.html Physics Tue, 22 Dec 2009 04:58:18 EST news180680263 At Berkeley Lab's National Center for Electron Microscopy it was revealed that single-stranded DNA can disperse bundles of single-walled carbon nanotubes into individual tubes and serve as guideposts for synthesizing platinum nanoparticles onto these tubes. http://www.physorg.com/news180644226.html Nanotechnology Mon, 21 Dec 2009 19:10:01 EST news180644226 (PhysOrg.com) -- In excess of seven million barrels of gasoline are consumed by vehicles in the United States every day. As scientists race to find environmentally sound solutions to fuel the world`s ever-growing transportation needs, battery researchers are exploring the promise of lithium-air battery technology. http://www.physorg.com/news180639792.html Technology Mon, 21 Dec 2009 17:43:41 EST news180639792 (PhysOrg.com) -- Engineering professor's nanorobot could be performing non-invasive surgical procedures on patients with tumors within the next decade. http://www.physorg.com/news180637694.html Nanotechnology Mon, 21 Dec 2009 17:40:07 EST news180637694 Researchers at the California Institute of Technology (Caltech) have proposed a new paradigm that should allow scientists to observe quantum behavior in small mechanical systems. http://www.physorg.com/news180632559.html Physics Mon, 21 Dec 2009 15:44:00 EST news180632559 (PhysOrg.com) -- University of California, Riverside Professor of Electrical Engineering and Chair of Materials Science and Engineering Alexander Balandin is leading several projects to explore ways to use the unique capabilities of graphene ?quilts? as heat conductors in high-power electronics. http://www.physorg.com/news180628388.html Nanotechnology Mon, 21 Dec 2009 14:34:22 EST news180628388 (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 (PhysOrg.com) -- Just like our roads, there is a lot of traffic within the cells in our bodies, because cell components, messenger molecules, and enzymes must also be brought to the right places in the cell. One of these transportation systems functions like a kind of railway: a system of molecular tracks is used to transport vesicles and their contents to their target destinations. http://www.physorg.com/news180602012.html Chemistry Mon, 21 Dec 2009 07:14:11 EST news180602012 (PhysOrg.com) -- Boston University biomedical engineers have devised a method for making future genome sequencing faster and cheaper by dramatically reducing the amount of DNA required, thus eliminating the expensive, time-consuming and error-prone step of DNA amplification. http://www.physorg.com/news180531065.html Nanotechnology Sun, 20 Dec 2009 13:00:03 EST news180531065 (PhysOrg.com) -- In a recent study, researchers have examined the possibility of rolling a nanorod on the surface of water. On the macroscale, perhaps the closest analogy might be the sport of logrolling, in which two competitors try to balance on a log the longest while the log rolls on water. However, while the macro log rolls due to the competitors walking on it, the nanorod would roll by becoming electrically polarized by a beam of light. http://www.physorg.com/news180352909.html Nanotechnology Fri, 18 Dec 2009 10:40:01 EST news180352909 (PhysOrg.com) -- In 1996, when scientists examined a meteorite from Mars previously uncovered in Antarctica, they were intrigued by what looked like microscopic fossils of ancient Martian life forms. Now, using new technology that wasn't available 13 years ago, NASA scientists have found further evidence that the materials and structures in the meteorite are likely signs of ancient life, rather than the results of inorganic processes. http://www.physorg.com/news180264793.html Space & Earth Thu, 17 Dec 2009 09:33:52 EST news180264793 A single-atom-thick sheet of carbon, like those seen in pencil marks -- offers great potential for new types of nanoscale devices, if a good way can be found to mold the material into desired shapes. http://www.physorg.com/news180256587.html Nanotechnology Thu, 17 Dec 2009 07:18:00 EST news180256587
