(PhysOrg.com) -- Architecture could help us tackle climate change, if we start to design our buildings with 'living' materials, according to Dr Rachel Armstrong, UCL Bartlett School of Architecture. http://www.physorg.com/news178528786.html Other Sciences Fri, 27 Nov 2009 07:30:01 EST news178528786 Stents that keep weakened and flabby arteries from collapsing have been true life-savers. But after six months, those stents are no longer needed -- once the arteries are strengthened, they become unnecessary. Previously, doctors had no choice but to leave them in place. http://www.physorg.com/news178284711.html Biology Tue, 24 Nov 2009 11:48:28 EST news178284711 In an advance that could help ease health and environmental concerns about the emerging nanotechnology industry, scientists are reporting development of technology for changing the behavior of nanoparticles in municipal sewage treatment plants - their main gateway into the environment. Their study will be published online November 12 in ACS' journal Environmental Science & Technology. http://www.physorg.com/news177242892.html Space & Earth Thu, 12 Nov 2009 10:09:08 EST news177242892 (PhysOrg.com) -- UConn researchers have developed a tiny wireless device that can be inserted under a patient?s skin to monitor blood glucose levels over a period of several months. http://www.physorg.com/news177018067.html Medicine & Health Mon, 09 Nov 2009 20:20:05 EST news177018067 A very close and detailed study of how the most robust antibodies work to block the HIV virus as it seeks entry into healthy cells has revealed a new direction for researchers hoping to design an effective vaccine. http://www.physorg.com/news177008235.html Medicine & Health Mon, 09 Nov 2009 16:58:05 EST news177008235 (PhysOrg.com) -- Researchers at Yale University have developed synthetic molecules capable of enhancing the body`s immune response to HIV and HIV-infected cells, as well as to prostate cancer cells. Their findings, published online in the Journal of the American Chemical Society, could lead to novel therapeutic approaches for these diseases. http://www.physorg.com/news176659510.html Chemistry Thu, 05 Nov 2009 16:07:03 EST news176659510 Inside a cramped back room at Rushford Hypersonic, a start-up headquartered in southeastern Minnesota, sits a cube-like machine that throws a mean atomic fastball. At the push of a button, the reactor hurls atoms toward a substrate material at eight times faster than the speed of sound. http://www.physorg.com/news176637826.html Nanotechnology Thu, 05 Nov 2009 11:10:02 EST news176637826 (PhysOrg.com) -- Evidence for a thin veil of carbon has been found on the neutron star in the Cassiopeia A supernova remnant. This discovery, made with NASA's Chandra X-ray Observatory, resolves a ten-year mystery surrounding this object. http://www.physorg.com/news176567767.html Space & Earth Wed, 04 Nov 2009 14:37:05 EST news176567767 (PhysOrg.com) -- Our breakfast egg is a peculiarity of nature: a single cell protected by a thin mineral layer. Apart from a number of tiny radiolaria and diatoms, individual cells normally do not have a hard shell. Korean researchers have now developed a strategy for equipping individual cells of baker`s yeast, Saccharomyces cerevisiae, with a synthetic shell made of silicon dioxide. As the team led by Insung S. Choi reports in the journal Angewandte Chemie, the lifespan of these coated yeast cells is tripled, whilst their division is suppressed. The shell also protects the cells from unfavorable external conditions. http://www.physorg.com/news176474495.html Chemistry Tue, 03 Nov 2009 12:47:08 EST news176474495 Converting sunlight to electricity might no longer mean large panels of photovoltaic cells atop flat surfaces like roofs. http://www.physorg.com/news176389079.html Nanotechnology Mon, 02 Nov 2009 12:59:21 EST news176389079 (PhysOrg.com) -- CSIRO has developed a novel coating technology, "Quench Coat", to protect galvanised products from 'white rust' ? the form of zinc oxide that tarnishes freshly galvanised coatings, making them look dull. http://www.physorg.com/news176106672.html Chemistry Fri, 30 Oct 2009 07:50:01 EST news176106672 (PhysOrg.com) -- Preventing the havoc wrought when freezing rain collects on roads, power lines, and aircrafts could be only a few nanometers away. A University of Pittsburgh-led team demonstrates in the Nov. 3 edition of Langmuir a nanoparticle-based coating developed in the lab of Di Gao, a chemical and petroleum engineering professor in Pitt's Swanson School of Engineering, that thwarts the buildup of ice on solid surfaces and can be easily applied. http://www.physorg.com/news176044143.html Chemistry Thu, 29 Oct 2009 14:09:54 EST news176044143 (PhysOrg.com) -- A company that makes steel for bearings used in heavy trucks had a big problem. The trucks travel through harsh, perilous environments such as Siberia, and an unexpected bearing failure on a remote stretch could literally put the driver's life in danger. Knowing how long the steel would hold up under those conditions was beyond their ability to predict experimentally, so they turned to specialists at MIT. http://www.physorg.com/news175952830.html Technology Wed, 28 Oct 2009 12:48:04 EST news175952830 (PhysOrg.com) -- Biologists led by associate professor Thomas Schwartz (MIT) have worked out a rudimentary architectural plan for the nuclear pore complex (NPC), the gatekeeper of the cell's nucleus. http://www.physorg.com/news175881788.html Biology Tue, 27 Oct 2009 17:04:11 EST news175881788 (PhysOrg.com) -- Researchers at the Georgia Institute of Technology have won a $6.5 million grant to develop improved components that will boost the efficiency of electric propulsion systems used to control the positions of satellites and planetary probes. http://www.physorg.com/news175365546.html Nanotechnology Wed, 21 Oct 2009 18:30:01 EST news175365546
