(PhysOrg.com) -- Just a few decades ago, scientists believed that all ordered matter consists of self-repeating building blocks -- atoms, ions or molecules. In this view, the ordinary solids of everyday life are arranged in crystals of repeating, three -- dimensional patterns. http://www.physorg.com/news176214864.html Nanotechnology Sat, 31 Oct 2009 13:34:52 EST news176214864 Rice University scientists have won a $1.5 million grant from the National Institutes of Health to scrutinize the influenza A virus for clues that could lead to more effective antiviral drugs. Strains of influenza A include this year's pandemic H1N1 variety, some seasonal varieties and the much-feared H5N1 bird flu. http://www.physorg.com/news175258753.html Biology Tue, 20 Oct 2009 12:10:04 EST news175258753 By discovering the atomic structure of a key human enzyme, researchers at The University of Texas at Austin have pointed the way toward designing anti-HIV drugs with far less toxic side effects. http://www.physorg.com/news174833926.html Biology Thu, 15 Oct 2009 14:10:01 EST news174833926 (PhysOrg.com) -- Researchers have overcome a major obstacle in efforts to use tiny structures called carbon nanotubes to create a new class of electronics that would be faster and smaller than conventional silicon-based transistors. http://www.physorg.com/news173626785.html Nanotechnology Thu, 01 Oct 2009 14:40:28 EST news173626785 (PhysOrg.com) -- John Spence, a physicist at Arizona State University, is a longtime user of the Advanced Light Source at Lawrence Berkeley National Laboratory, where he has contributed to major advances in lensless imaging. It`s a particularly apt propensity for someone who works with x-rays, since they can`t be focused with ordinary lenses. http://www.physorg.com/news168620492.html Physics Tue, 04 Aug 2009 16:20:01 EST news168620492 John Spence, a physicist at Arizona State University, is a longtime user of the Advanced Light Source at Lawrence Berkeley National Laboratory, where he has contributed to major advances in lensless imaging.

The sculpture is one of three works of science art portraying carbon made in recent weeks by the University of Keele, and called collectively Carbon Rapture. http://www.physorg.com/news167290123.html Nanotechnology Mon, 20 Jul 2009 06:38:40 EST news167290123 Research led by David Worthylake, PhD, Assistant Professor of Biochemistry and Molecular Biology at LSU Health Sciences Center New Orleans, may help lay the groundwork for the development of a compound to prevent the spread of cancer. The research will be published in the May 29, 2009 issue of the Journal of Biological Chemistry. http://www.physorg.com/news162132055.html Chemistry Thu, 21 May 2009 13:41:33 EST news162132055 Proteins, the work-horse molecules necessary for virtually every human action from breathing to thinking, have proved an almost ghostly presence, daring scientists to fully grasp their structure and behavior. Now, physicists at the University of Wisconsin-Milwaukee have developed powerful imaging techniques that promise to tell us much more about what proteins are and what they do, how they change shapes and how they work together in a cell. http://www.physorg.com/news158941208.html Physics Tue, 14 Apr 2009 15:20:32 EST news158941208 Astronomy & Astrophysics is publishing the first clear detection of signatures long sought in the spectra of X-ray astronomical sources. These signatures, the so-called EXAFS standing for "Extended X-ray Absorption Fine Structure", were observed with an X-ray spectroscopic technique that is common in materials sciences. http://www.physorg.com/news157720762.html Space & Earth Tue, 31 Mar 2009 12:19:38 EST news157720762 (PhysOrg.com) -- The sonar on submarines may get far more sensitive ears in the near future thanks to a mysterious compound developed by the military. Developed over a decade ago, it took a collaboration of scientists from the Virginia Polytechnic Institute and State University and the National Institute of Standards and Technology to determine why the material works. Surprisingly, the critical factor is a sprinkling of useful imperfections within an otherwise regular crystal. http://www.physorg.com/news157207921.html Physics Wed, 25 Mar 2009 13:52:29 EST news157207921 Scientists at the University of Liverpool and Durham University have developed a new material to further understanding of how superconductors could be used to transmit electricity to built-up areas and reduce global energy losses. http://www.physorg.com/news156695024.html Physics Thu, 19 Mar 2009 15:24:34 EST news156695024 (PhysOrg.com) -- A new imaging technique developed by researchers at the University of Illinois overcomes the limit of diffraction and can reveal the atomic structure of a single nanocrystal with a resolution of less than one angstrom. http://www.physorg.com/news154189424.html Nanotechnology Wed, 18 Feb 2009 14:27:27 EST news154189424 (PhysOrg.com) -- IBM Research scientists, in collaboration with the Center for Probing the Nanoscale at Stanford University, have demonstrated magnetic resonance imaging (MRI) with volume resolution 100 million times finer than conventional MRI. http://www.physorg.com/news151073713.html Nanotechnology Tue, 13 Jan 2009 12:55:13 EST news151073713 For more than 15 years, carbon nanotubes (CNTs) have been the flagship material of nanotechnology. Researchers have conceived applications for nanotubes ranging from microelectronic devices to cancer therapy. Their atomic structure should, in theory, give them mechanical and electrical properties far superior to most common materials. http://www.physorg.com/news138023557.html Nanotechnology Fri, 15 Aug 2008 12:52:37 EST news138023557
