(PhysOrg.com) -- How can some sportsmen and women, in the heat of the moment, play on through pain that would floor anyone else? Bert Trautmann, the Manchester City goalkeeper, famously played on through to the end of the 1956 FA Cup final - holding on for a 3-1 win - despite suffering a broken neck from a collision in the second half. http://www.physorg.com/news179053650.html Medicine & Health Thu, 03 Dec 2009 09:08:11 EST news179053650 Scientists in Washington, DC, are reporting development and successful tests of a new way for exploring the insides of living cells, the microscopic building blocks of all known plants and animals. They explode the cell while it is still living inside a plant or animal, vaporize its contents, and sniff. The study appears in online in ACS' journal Analytical Chemistry. http://www.physorg.com/news177171735.html Chemistry Wed, 11 Nov 2009 14:40:08 EST news177171735 (PhysOrg.com) -- Standard laser devices are fast enough for measuring the size of a room, but they need to be faster for outdoor mobile applications. Researchers have brought these scanners up to speed -- they can measure ten times faster than usual scanners. http://www.physorg.com/news176623864.html Technology Thu, 05 Nov 2009 06:50:03 EST news176623864 (PhysOrg.com) -- Polishing metal surfaces is a demanding but monotonous task, and it is difficult to find qualified young specialists. Polishing machines do not represent an adequate alternative because they cannot get to difficult parts of the surface. A new solution is provided by laser polishers. http://www.physorg.com/news176456761.html Technology Tue, 03 Nov 2009 08:40:01 EST news176456761 (PhysOrg.com) -- The first experiments are now underway using the world's most powerful X-ray laser, the Linac Coherent Light Source, located at the Department of Energy's SLAC National Accelerator Laboratory. Illuminating objects and processes at unprecedented speed and scale, the LCLS has embarked on groundbreaking research in physics, structural biology, energy science, chemistry and a host of other fields. http://www.physorg.com/news176388048.html Physics Mon, 02 Nov 2009 13:10:07 EST news176388048 An international team of physicists at Los Alamos National Laboratory has succeeded in using intense laser light to accelerate protons to energies never before achieved. Using this technique, scientists can now accelerate particles to extremely high velocities that would otherwise only be possible using large accelerator facilities. Physicists around the world are examining laser particle acceleration and laser produced radiation for potential future uses in cancer treatment. http://www.physorg.com/news176375335.html Physics Mon, 02 Nov 2009 09:09:30 EST news176375335 (PhysOrg.com) -- Biomedical researchers at the University of Arkansas in Fayetteville and the University of Arkansas for Medical Sciences (UAMS) in Little Rock have developed a special contrast-imaging agent made of gold-coated carbon nanotubes that is capable of molecular mapping of lymphatic endothelial cells and detecting cancer metastasis in sentinel lymph nodes. The findings from this study, which was led by Jin-Woo Kim, Ph.D., M.S., University of Arkansas, and Vladimir P. Zharov, Ph.D., D.Sc., M.S., UAMS, were published in the journal Nature Nanotechnology. http://www.physorg.com/news172951791.html Nanotechnology Thu, 24 Sep 2009 17:10:01 EST news172951791 Scientists at the Naval Research Laboratory (NRL) are developing a new technology for use in underwater acoustics. The new technology uses flashes of laser light to remotely create underwater sound. The new acoustic source has the potential to expand and improve both Naval and commercial underwater acoustic applications, including undersea communications, navigation, and acoustic imaging. http://www.physorg.com/news171284762.html Physics Fri, 04 Sep 2009 12:08:41 EST news171284762 Predatory fish are well aware of the problem: In a swarm of small fish it is hard to isolate prey. A similar situation can be found in the microcosm of atoms and molecules, whose behavior is influenced by "swarms" of electrons. In order to achieve control over single electrons in a bunch, ultrashort light pulses of a few femtoseconds duration are needed. http://www.physorg.com/news171031838.html Physics Tue, 01 Sep 2009 13:51:15 EST news171031838 (PhysOrg.com) -- An ultra-powerful laser can turn regular incandescent light bulbs into power-sippers, say optics researchers at the University of Rochester. The process could make a light as bright as a 100-watt bulb consume less electricity than a 60-watt bulb while remaining far cheaper and radiating a more pleasant light than a fluorescent bulb can. http://www.physorg.com/news162821951.html Physics Fri, 29 May 2009 13:20:03 EST news162821951 Ultrafast laser research at Kansas State University has allowed physicists to build on Nobel Prize-winning work in photo-electronics by none other than Albert Einstein. http://www.physorg.com/news162131852.html Physics Thu, 21 May 2009 13:38:14 EST news162131852 (PhysOrg.com) -- When studying cold atoms, scientists often use magnetic or optical traps to keep the atoms in place. However, in some cases experimentalists want to study free atoms, avoiding the effects of a trap. "One way to study free atoms," Cass Sackett tells PhysOrg.com, "is by bouncing them off a surface... most of the time, the atoms are free." He says that scientists have been interested in bouncing atoms for a long time, but that before now only about five bounces have been achieved. "Using magnets and certain lasers, it is possible to bounce atoms. However, they are lost relatively quickly." http://www.physorg.com/news160053848.html Physics Mon, 27 Apr 2009 12:24:47 EST news160053848 (PhysOrg.com) -- Don't be fooled by the collection of empty soda bottles in James Cryan's office at SLAC National Accelerator Laboratory. Cryan isn't a caffeine fiend -the cola bottles are for science. As a graduate student with the PULSE Institute for Ultrafast Energy Science, he is studying how nitrogen gas responds to stimulation by an optical laser, and he needed a container for the gas. Instead of ordering a cell and waiting for it to arrive, Cryan cast about for something close at hand -and happened upon one of the empty Coke bottles on his desk. http://www.physorg.com/news159123961.html Physics Thu, 16 Apr 2009 18:06:43 EST news159123961 Chemists can analyze the composition of a suspected bomb -- without actually touching and possibly detonating it -- using a technique called laser-induced breakdown spectroscopy, or LIBS. The tool is also commonly used for "stand-off" detection in such harsh or potentially dangerous environments as blast furnaces, nuclear reactors and biohazard sites and on unmanned planetary probes like the Mars rovers. http://www.physorg.com/news155994383.html Chemistry Wed, 11 Mar 2009 12:46:55 EST news155994383 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 Theoretical physicist Uwe Thumm and his colleagues Feng He and Andreas Becker not only work with some of the smallest molecules in the universe, but they now have found a way to control the motion of the molecules' building blocks, electrons and nuclei. http://www.physorg.com/news145818018.html Physics Thu, 13 Nov 2008 17:00:18 EST news145818018
