Berkeley Lab researchers have engineered a new class of bowtie-shaped devices that capture, filter and steer light at the nanoscale. These "nano-colorsorter" devices act as antennae to focus and sort light in tiny spaces, a useful technique for harvesting broadband light for color-sensitive filters and detectors. http://www.physorg.com/news177251056.html Nanotechnology Thu, 12 Nov 2009 12:25:15 EST news177251056 Scientists at the University of Adelaide have made a breakthrough that could change the world's thinking on what light is capable of. http://www.physorg.com/news177244484.html Physics Thu, 12 Nov 2009 11:00:02 EST news177244484 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 Rogue waves -- giant waves that spring up suddenly and tower over the seas around them -have inspired physicists to look for an analogue in light. These high-intensity pulses can cross large distances without losing information. Now a team of physicists have identified one set of conditions that produces optical rogue waves. Their findings are reported in Physical Review A and highlighted with in the October 19 issue of Physics. http://www.physorg.com/news175172691.html Physics Mon, 19 Oct 2009 12:05:41 EST news175172691 (PhysOrg.com) -- Quantum key distribution (QKD) could be the next commercial success of quantum physics, and a recent study has taken the field a step closer to this reality. Researchers from the University of Geneva in Switzerland and Corning Incorporated in New York have demonstrated a new QKD prototype that can distribute quantum keys over a distance of 250 km in the lab, improving upon the previous record of 200 km. The scientists hope that the achievement will lead to the goal of distributing quantum keys over intercity distances of 300 km in the near future. http://www.physorg.com/news167390366.html Physics Tue, 21 Jul 2009 10:19:59 EST news167390366 (PhysOrg.com) -- The world`s largest computing grid has passed its most comprehensive tests to date in anticipation of the restart of the world`s most powerful particle accelerator, the Large Hadron Collider (LHC). The successful dress rehearsal proves that the Worldwide LHC Computing Grid (WLCG) is ready to analyze and manage real data from the massive machine. The United States is a vital partner in the development and operation of the WLCG, with 15 universities and three U.S. Department of Energy (DOE) national laboratories from 11 states contributing to the project. http://www.physorg.com/news165680293.html Physics Wed, 01 Jul 2009 15:50:01 EST news165680293 Scientists have studied high-frequency brain waves, known as gamma oscillations, for more than 50 years, believing them crucial to consciousness, attention, learning and memory. Now, for the first time, MIT researchers and colleagues have found a way to induce these waves by shining laser light directly onto the brains of mice. http://www.physorg.com/news159973187.html Medicine & Health Sun, 26 Apr 2009 14:00:19 EST news159973187 (PhysOrg.com) -- Engineering researchers at the University of Arkansas have fabricated and tested a unique biosensor that measures concentrations of potassium and hydrogen ions in the human heart with high specificity. The research could lead to a superior method of monitoring indicators of acute myocardial ischemia, or AMI, one of the leading causes of cardiovascular failure. http://www.physorg.com/news159719279.html Physics Thu, 23 Apr 2009 15:28:48 EST news159719279 A research team lead by Karl Deisseroth in the bioengineering department at Stanford University has developed a technique to systematically characterize disease circuits in the brain. By precisely controlling individual components of the circuit implicated in Parkinson's disease, the team has identified a specific group of cells as direct targets of deep brain stimulation (DBS), a Parkinson's treatment. http://www.physorg.com/news159110689.html Medicine & Health Thu, 16 Apr 2009 14:25:23 EST news159110689 (AP) -- Cablevision Systems Corp. should stop saying its Internet service is "the fastest around," the advertising industry's self-regulatory body said Thursday, in response to complaints from competitor Verizon Communications Inc. http://www.physorg.com/news157372389.html Technology Fri, 27 Mar 2009 11:33:43 EST news157372389 To cut the cost of bringing high-speed Internet to rural areas, Dr. Ka Lun Lee and colleagues at the University of Melbourne and NEC Australia in the state of Victoria are experimenting with a way to boost the reach of existing technology. Their results, which show a new way to cheaply cover 99 percent of those living in this province, will be presented during the Optical Fiber Communication Conference and Exposition/National Fiber Optic Engineers Conference (OFC/NFOEC), taking place March 22-26 in San Diego. http://www.physorg.com/news156428604.html Technology Mon, 16 Mar 2009 13:24:08 EST news156428604 A freak wave at sea is a terrifying sight. Seven stories tall, wildly unpredictable, and incredibly destructive, such waves have been known to emerge from calm waters and swallow ships whole. But rogue waves of light -- rare and explosive flare-ups that are mathematically similar to their oceanic counterparts -- have recently been tamed by a group of researchers at the University of California, Los Angeles (UCLA). http://www.physorg.com/news155478110.html Physics Thu, 05 Mar 2009 12:22:15 EST news155478110 Sliced light is how we communicate now. Millions of phone calls and cable television shows per second are dispatched through fibers in the form of digital zeros and ones formed by chopping laser pulses into bits. This slicing and dicing is generally done with an electro-optic modulator, a device for allowing an electric signal to switch a laser beam on and off at high speeds (the equivalent of putting your hand in front of a flashlight). Reading that fast data stream with a compact and reliable receiver is another matter. A new error-free speed-reading record using a compact ultra-fast component -640 Gbits/second (Gbps, or billion bits per second) -has now been established by a collaboration of scientists from Denmark and Australia, who report their results in the journal Optics Express. http://www.physorg.com/news152803534.html Technology Mon, 02 Feb 2009 13:26:02 EST news152803534 Scientists at Clemson University for the first time have been able to make a practical optical fiber with a silicon core, according to a new paper published in the current issue of the Optical Society's open-access journal, Optics Express. http://www.physorg.com/news144393381.html Physics Tue, 28 Oct 2008 06:16:21 EST news144393381 (PhysOrg.com) -- For several years, physicists have known that liquid columns can be used to guide light. By trapping a light beam, a liquid column can act like an optical fiber, but with a liquid sheathing instead of glass or plastic. http://www.physorg.com/news136555463.html Physics Tue, 29 Jul 2008 13:04:23 EST news136555463
