(PhysOrg.com) -- The genesis of one the planet's most lethal viruses, HIV, has been caught on tape. New imaging experiments show individual HIV genomes -- strands of RNA - docking on the inner membrane of an infected cell wall as they are ensconced by HIV structural proteins. http://www.physorg.com/news177696439.html Medicine & Health Tue, 17 Nov 2009 16:07:49 EST news177696439 Current methods of detecting breast cancer suffer from low sensitivity, limited spatial resolution, or the need to use complicated and expensive radioisotope-based technologies. A new report from investigators at the Emory-Georgia Tech Nanotechnology Center for Personalized and Predictive Oncology suggests that targeted iron oxide nanoparticles may overcome these limitations and could serve as novel imaging agents for the early detection of breast tumors. http://www.physorg.com/news167412130.html Nanotechnology Tue, 21 Jul 2009 16:50:01 EST news167412130 (PhysOrg.com) -- A crucial tool in the evolution of scientific capability in bioscience, the fluorescence microscope has allowed a generation of scientists to study the properties of proteins inside cells. Yet as human capacity for discovery has zoomed to the nanoscale, fluorescence microscopy has struggled to keep up. Now, a team that includes UGA engineer Peter Kner has developed a microscope that is capable of live imaging at double the resolution of fluorescence microscopy using structured illumination. http://www.physorg.com/news160843613.html Chemistry Wed, 06 May 2009 15:47:43 EST news160843613 In a finding that could help speed the understanding of diseases ranging from cancer to osteoporosis, researchers in Utah are reporting development of a new microscope technique that uses `silver nanoparticle` mirrors to reveal hidden details inside bones, cancer cells, and other biological structures. The method also can help identify structural damage in a wide variety of materials, including carbon-fiber plastics used in airplanes, the researchers say. http://www.physorg.com/news154894368.html Nanotechnology Thu, 26 Feb 2009 18:13:19 EST news154894368 Remarkable new tools that spotlight individual cellular molecules are transforming biomedical research. Scientists at the Gruss Lipper Biophotonics Center at the Albert Einstein College of Medicine of Yeshiva University have spearheaded their use in a series of papers, including one published today in the online version of Nature Methods. http://www.physorg.com/news152114553.html Biology Sun, 25 Jan 2009 14:03:07 EST news152114553 Thanks to a new "super-resolution" fluorescence microscopy technique, Harvard University researchers have succeeded in resolving the features of cells as miniscule as 20-30 nanometers (nm), an order of magnitude smaller than conventional fluorescence light microscopy images, according to a presentation at the American Society for Cell Biology (ASCB) 48th Annual Meeting, Dec. 13-17, 2008, in San Francisco. http://www.physorg.com/news148656934.html Biology Tue, 16 Dec 2008 13:35:34 EST news148656934
