Seeking to turn an environmental problem into an economic opportunity, high-tech companies in resource-poor Japan are mining mountains of toxic e-waste for precious materials. http://www.physorg.com/news180266038.html Space & Earth Thu, 17 Dec 2009 10:10:01 EST news180266038 Not so long ago our computers had a single core which had to be boosted for performance - making each machine into a great central heating system. Beyond 85° C, however, electronic components become unstable. To overcome this physical limit, a solution was found with the multicore technology, where the same chip includes several processors which share tasks. Most of today's consumer electronics proudly boast a "dual core" or "quad core". However, in time the technology will come up against the same physical limits. http://www.physorg.com/news179755670.html Technology Fri, 11 Dec 2009 12:10:05 EST news179755670 (PhysOrg.com) -- Computer chips that transmit data with light instead of electricity consume much less power than conventional chips, but so far, they've remained laboratory curiosities. Professors Vladimir Stojanović and Rajeev Ram and their colleagues in MIT's Research Laboratory of Electronics and Microsystems Technology Laboratory hope to change that, by designing optical chips that can be built using ordinary chip-manufacturing processes. http://www.physorg.com/news178298113.html Technology Tue, 24 Nov 2009 15:15:49 EST news178298113 Up to now, extreme production temperatures made it impossible to equip metallic components with RFID chips during the operating process. At Euromold in Frankfurt (Dec. 2-5), Germany, Fraunhofer researchers present a variation on a process that makes the non-destructive integration of radio chips a reality. http://www.physorg.com/news178279408.html Technology Tue, 24 Nov 2009 10:20:02 EST news178279408 Infectious organisms that become resistant to antibiotics are a serious threat to human society. They are also a natural part of evolution. In a new project, researchers at the University of Gothenburg are attempting to find substances that can slow the pace of evolution, in order to ensure that the drugs of today remain effective into the future. http://www.physorg.com/news177611481.html Biology Mon, 16 Nov 2009 16:31:52 EST news177611481 (PhysOrg.com) -- For the first time, it has been possible to measure electron density in individual molecular states using what is known as the photoelectric effect. Now published in Science, this method represents a key building block in the development of organic semiconductor elements. Supported by the Austrian Science Fund FWF, the success of this project rested on the mathematical transformation of the measured data. This made it possible to interpret the distribution of the electrons and draw conclusions about the potential properties of organic semiconductor elements. http://www.physorg.com/news177582885.html Physics Mon, 16 Nov 2009 08:35:28 EST news177582885 (PhysOrg.com) -- Xerox has developed an ink which can be used to print circuits onto plastics, films, and textiles.

But not all of the little legumes' treasure trove of iron is bioaccessible -- that is, available for our bodies to readily absorb. http://www.physorg.com/news173103145.html Biology Fri, 25 Sep 2009 13:30:01 EST news173103145 The sandwich recipe recently concocted by scientists working at the National Institute of Standards and Technology may prove tasty for computer chip designers, who have long had an appetite for molecule-sized electronic components - but no clear way to satisfy it until now. http://www.physorg.com/news170517055.html Chemistry Wed, 26 Aug 2009 14:51:51 EST news170517055 Between the 1932 and 2008 Olympic Games, world record times of the men's 100m sprint improved by 0.6 seconds. Scientists at the Research Institute of Wildlife Ecology in Austria have shown that an equivalent improvement can be achieved in mice by feeding them a diet high in a certain type of polyunsaturated fatty acid. Dr. Christopher Turbill will present the research at the Society for Experimental Biology meeting on Monday, June 29. http://www.physorg.com/news165474068.html Biology Mon, 29 Jun 2009 06:01:59 EST news165474068 Researchers at Iowa State University have found that increased expression of a form of cytochrome P-450 (CYP4B1) is a key marker of inhibition of colitis in mice by caffeic acid, an anti-inflammatory antioxidant compound widely distributed in foods. http://www.physorg.com/news162553970.html Medicine & Health Tue, 26 May 2009 10:53:31 EST news162553970 The swine flu outbreak that began in Mexico and continues to spread around the globe may be particularly dangerous for young, otherwise healthy adults because it contains genetic components of the H5N1 avian influenza virus, which can induce a "cytokine storm," in which a patient's hyper-activated immune system causes potentially fatal damage to the lungs. Research studies and review articles exploring the regulation of cytokine responses in the lung and how infection-related dysregulation can cause a cytokine storm have been published in Viral Immunology, a peer-reviewed journal published by Mary Ann Liebert, Inc. http://www.physorg.com/news160761170.html Medicine & Health Tue, 05 May 2009 16:53:21 EST news160761170 IMEC reports a method to integrate high-speed CMOS electronics and nanophotonic circuitry based on plasmonic effects. Metal-based nanophotonics (plasmonics) can squeeze light into nanoscale structures that are much smaller than conventional optic components. Plasmonic technology, today still in an experimental stage, has the potential to be used in future applications such as nanoscale optical interconnects for high performance computer chips, extremely sensitive (bio)molecular sensors, and highly efficient thin-film solar cells. IMEC`s results are published in the May issue of Nature Photonics. http://www.physorg.com/news160290454.html Physics Thu, 30 Apr 2009 06:09:00 EST news160290454 The swine flu virus that is smoldering in this country and triggering a full-blown outbreak in Mexico is one of a growing number of animal pathogens to jump the species barrier -- and may be the microbe that jumpstarts the first globe-circling pandemic of the 21st century, experts said Tuesday. http://www.physorg.com/news160210564.html Medicine & Health Wed, 29 Apr 2009 07:56:30 EST news160210564 Researchers have developed a technology that detects damage to critical suspension components in military vehicles simply by driving over a speed bumplike "diagnostic cleat" containing sensors. http://www.physorg.com/news158856565.html Technology Mon, 13 Apr 2009 15:50:14 EST news158856565 By combining the results of a number of powerful techniques for studying material structure at the nanoscale, a team of researchers from the National Institute of Standards and Technology, working with colleagues in other federal labs and abroad, believe they have settled a long-standing debate over the source of the unique electronic properties of a material with potentially great importance for wireless communications. http://www.physorg.com/news158417087.html Physics Wed, 08 Apr 2009 13:45:24 EST news158417087 By combining the trusty old book, pen and paper with the possibilities offered by the computer and the interactive whiteboard, ICT can help to improve students` understanding in maths education.
