(PhysOrg.com) -- The first experiment using the Linac Coherent Light Source to illuminate molecules via a "pump-probe" technique has been completed by an international team of more than 30 scientists from institutions including Lawrence Berkeley National Laboratory, LCLS and the joint SLAC/Stanford PULSE Institute. Ryan Coffee, physicist with the LCLS Laser Group, presented initial results in a seminar at SLAC on Wednesday, November 18. http://www.physorg.com/news178822370.html Physics Mon, 30 Nov 2009 17:30:03 EST news178822370 An international team of applied scientists from Harvard, Hamamatsu Photonics, and ETH Zürich have demonstrated compact, multibeam, and multi-wavelength lasers emitting in the invisible part of the light spectrum (infrared). By contrast, typical lasers emit a single light beam of a well-defined wavelength. The innovative multibeam lasers have potential use in applications related to remote chemical sensing pollution monitoring, optical wireless, and interferometry. http://www.physorg.com/news178804893.html Physics Mon, 30 Nov 2009 12:40:01 EST news178804893 Peatlands, especially those in tropical regions, sequester gigantic amounts of organic carbon. Human activities are now having a considerable impact on these wetlands. For example, drainage projects, in combination with the effects of periodic droughts, can lead to large-scale fires, which release enormous amounts of carbon dioxide (CO2) into the atmosphere, and thus contribute to global warming. http://www.physorg.com/news178803752.html Space & Earth Mon, 30 Nov 2009 11:43:01 EST news178803752 (PhysOrg.com) -- It may be a long time before we see robots shooting pucks and making saves in professional hockey, but second-year mechanical engineering students at the University of Alberta put some pretty impressive players to the test as part of a creative design course. http://www.physorg.com/news178449090.html Technology Thu, 26 Nov 2009 09:40:02 EST news178449090 (PhysOrg.com) -- Mention of arsenic poisoning usually brings to mind underhanded murder. However, the danger of arsenic poisoning from contaminated drinking water is far greater. Low concentrations of arsenic are found in nearly all soils and thus also in ground water. About 140 million people worldwide possibly drink water that contains arsenic concentrations above the WHO-recommended limit of 10 ppb (parts per billion). http://www.physorg.com/news178347619.html Nanotechnology Wed, 25 Nov 2009 05:02:58 EST news178347619 Suddenly seeing floaters or flashes of light may indicate a serious eye problem that - if untreated - could lead to blindness, a new study shows. http://www.physorg.com/news178315342.html Medicine & Health Tue, 24 Nov 2009 20:40:05 EST news178315342 (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 The dusty boxes that line the walls of Jeff Barrett's UC Irvine office mark a high point in his academic career.
