(PhysOrg.com) -- Researchers in the United States and Spain have discovered that a tool widely used in nanoscale imaging works differently in watery environments, a step toward better using the instrument to study biological molecules and structures. http://www.physorg.com/news169224439.html Nanotechnology Tue, 11 Aug 2009 16:40:01 EST news169224439 Biomolecular computers, made of DNA and other biological molecules, only exist today in a few specialized labs, remote from the regular computer user. Nonetheless, Tom Ran and Shai Kaplan, research students in the lab of Prof. Ehud Shapiro of the Weizmann Institute's Biological Chemistry, and Computer Science and Applied Mathematics Departments have found a way to make these microscopic computing devices 'user friendly,' even while performing complex computations and answering complicated queries. http://www.physorg.com/news168510956.html Nanotechnology Mon, 03 Aug 2009 09:40:51 EST news168510956 Four of the biologists who described the underlying causes of aging will soon share their findings with an international audience during a symposium at the upcoming World Congress of Gerontology and Geriatrics, taking place from July 5-9, 2009, in Paris, France. http://www.physorg.com/news164977370.html Medicine & Health Tue, 23 Jun 2009 12:03:19 EST news164977370 (PhysOrg.com) -- The recent explosion in the development of nanomaterials with enhanced performance characteristics for use in commercial and medical applications has increased the likelihood of people coming into direct contact with these materials. http://www.physorg.com/news164638938.html Nanotechnology Fri, 19 Jun 2009 14:03:06 EST news164638938 (PhysOrg.com) -- The world's brightest X-ray source sprang to life last week at the U.S. Department of Energy's SLAC National Accelerator Laboratory. The Linac Coherent Light Source (LCLS) offers researchers the first-ever glimpse of high-energy or "hard" X-ray laser light produced in a laboratory. http://www.physorg.com/news159556347.html Physics Tue, 21 Apr 2009 18:12:48 EST news159556347 (PhysOrg.com) -- NASA scientists analyzing the dust of meteorites have discovered new clues to a long-standing mystery about how life works on its most basic, molecular level. http://www.physorg.com/news156523757.html Chemistry Tue, 17 Mar 2009 15:50:05 EST news156523757 (PhysOrg.com) -- Researchers have created a precise biosensor for detecting blood glucose and potentially many other biological molecules by using hollow structures called single-wall carbon nanotubes anchored to gold-coated "nanocubes." http://www.physorg.com/news151854328.html Nanotechnology Thu, 22 Jan 2009 13:46:15 EST news151854328 (PhysOrg.com) -- A handheld, ultra-portable device that can recognize and immediately report on a wide variety of environmental or medical compounds may eventually be possible, using a method that incorporates a mixture of biologically tagged nanowires onto integrated circuit chips, according to Penn State researchers. http://www.physorg.com/news151252040.html Nanotechnology Thu, 15 Jan 2009 14:27:20 EST news151252040 (PhysOrg.com) -- A major goal of nanotechnology research is to create a "lab on a chip," in which a tiny biological sample would be carried through microscopic channels for processing. This could make possible portable, fast-acting detectors for disease organisms or food-borne pathogens, rapid DNA sequencing and other tests that now take hours or days. http://www.physorg.com/news150129386.html Nanotechnology Fri, 02 Jan 2009 14:36:26 EST news150129386
