A group of researchers in Tennessee and Denmark has discovered a way to sensitively detect explosives based on the physical properties of their vapors. Their technology, which is currently being developed into prototype devices for field testing, is described in the latest issue of the journal Review of Scientific Instruments, which is published by the American Institute of Physics. http://www.physorg.com/news156173204.html Physics Fri, 13 Mar 2009 14:27:16 EST news156173204 (PhysOrg.com) -- The territory where the Higgs boson may be found continues to shrink. The latest analysis of data from the CDF and DZero collider experiments at the U.S. Department of Energy's Fermilab now excludes a significant fraction of the allowed Higgs mass range established by earlier measurements. Those experiments predict that the Higgs particle should have a mass between 114 and 185 GeV/c2. Now the CDF and DZero results carve out a section in the middle of this range and establish that it cannot have a mass in between 160 and 170 GeV/c2. http://www.physorg.com/news156160849.html Physics Fri, 13 Mar 2009 11:01:43 EST news156160849 (PhysOrg.com) -- Up until now, George Grüner tells PhysOrg.com, most of the studies regarding the properties - and uses - of carbon nanotubes have been restricted to the visible spectral range. `We, however, were interested in the properties in infrared range, in the window of the electromagnetic spectrum that is gaining increased prominence.` http://www.physorg.com/news155816845.html Nanotechnology Mon, 09 Mar 2009 11:28:22 EST news155816845 (PhysOrg.com) -- Scientists of the CDF and DZero collaborations at the Department of Energy's Fermi National Accelerator Laboratory have observed particle collisions that produce single top quarks. The discovery of the single top confirms important parameters of particle physics, including the total number of quarks, and has significance for the ongoing search for the Higgs particle at Fermilab's Tevatron, currently the world's most powerful operating particle accelerator. http://www.physorg.com/news155816209.html Physics Mon, 09 Mar 2009 11:17:28 EST news155816209 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 Breast cancer patients 35 years old and younger have higher rates of their cancer returning after treatment than older women patients with the same stage of cancer, and their risk of recurrence is greatly impacted by the type of treatment they received, according to a March 1 study in the International Journal of Radiation Oncology*Biology*Physics, the official journal of the American Society for Radiation Oncology (ASTRO). http://www.physorg.com/news155397867.html Medicine & Health Wed, 04 Mar 2009 14:04:56 EST news155397867 In quantum mechanics, a vanguard of physics where science often merges into philosophy, much of our understanding is based on conjecture and probabilities, but a group of researchers in Japan has moved one of the fundamental paradoxes in quantum mechanics into the lab for experimentation and observed some of the 'spooky action of quantum mechanics' directly. http://www.physorg.com/news155386974.html Physics Wed, 04 Mar 2009 11:03:23 EST news155386974 (PhysOrg.com) -- Local realism is something we live with every day, even if we don`t realize it. The principle of local realism combines two assumptions: locality and realism. Locality says that distant objects cannot directly and instantaneously influence each other (since nothing can travel faster than the speed of light). Realism says that the things we measure and sense are indeed really there apart from our measurements, and it`s not just our measurements that make them exist. http://www.physorg.com/news155382024.html Physics Wed, 04 Mar 2009 09:40:56 EST news155382024 (PhysOrg.com) -- On the nanoscale, things aren`t always what they seem. What first looked like a continuous plasma jet has turned out to be a train of tiny, high-velocity plasma bullets. Using a camera with an exposure time of a few nanoseconds, researchers have further investigated the plasma bullets, and have even found a way to control them. http://www.physorg.com/news154951518.html Physics Fri, 27 Feb 2009 10:07:38 EST news154951518 Clemson University space physicists have traveled around the world to launch rockets to test atmospheric conditions. http://www.physorg.com/news154890259.html Space & Earth Thu, 26 Feb 2009 17:05:04 EST news154890259 (PhysOrg.com) -- `People are interested in the mid-infrared,` Dan Wasserman tells PhysOrg.com. Infrared light has a wavelength longer than visible light, and many molecules have numerous very strong optical resonances in the midinfrared. `Because of this, the midinfrared is an important wavelength range for trace gas sensing applications.` In addition the midinfrared is also of interest for applications such as thermal imaging, countermeasures, and even free space communication. http://www.physorg.com/news154609081.html Physics Mon, 23 Feb 2009 10:59:14 EST news154609081 Women who as children got radiation treatment for Hodgkin's disease are almost 40 times more likely than others to develop breast cancer, according to findings from five institutions, including the University of Florida. http://www.physorg.com/news153660140.html Medicine & Health Thu, 12 Feb 2009 11:23:22 EST news153660140 (PhysOrg.com) -- A Livermore researcher who teamed with a United Kingdom collaborator has published an article in Reviews of Modern Physics that refines decades of actinide science and may just become the preeminent research paper in the field. http://www.physorg.com/news153596330.html Physics Wed, 11 Feb 2009 17:39:33 EST news153596330 (PhysOrg.com) -- How many different sudokus are there?

These devices will be extremely small, making use of photons on the nanoscale, and (hopefully) be very efficient in terms of power use. The development of integrated photonic devices in tomorrow`s technology is taking place today at Peking University in Beijing, China, where a group of scientists has manufactured and tested a nanocomposite material that could be used in integrated photonic devices. http://www.physorg.com/news153406819.html Nanotechnology Mon, 09 Feb 2009 13:02:26 EST news153406819 Physicist Shou-Cheng Zhang has proposed a way to physically realize the magnetic monopole. In a paper published online in the January 29 issue of Science Express, Zhang and post-doctoral collaborator Xiao-Liang Qi predict the existence of a real-world material that acts as a magic mirror, in which the never-before-observed monopole appears as the image of an ordinary electron. If his prediction is confirmed by experiments, this could mean the opening of condensed matter as a new venue for observing the exotica of high-energy physics. http://www.physorg.com/news153074178.html Physics Thu, 05 Feb 2009 16:36:53 EST news153074178 Reporting of radiation therapy details in randomized controlled trials for Hodgkin's and non-Hodgkin's lymphoma is deficient due to a lack of reporting of key radiation therapy descriptors and quality assurance processes designed to ensure the accuracy and reproducibility of treatment regimens, according to a February 1 study in the International Journal of Radiation Oncology*Biology*Physics, the official journal of the American Society for Radiation Oncology. http://www.physorg.com/news152980469.html Medicine & Health Wed, 04 Feb 2009 14:35:13 EST news152980469 (PhysOrg.com) -- By integrating a solid-state electron emitter and a microcavity plasma device, researchers at the University of Illinois have created a plasma transistor that could be used to make lighter, less expensive and higher resolution flat-panel displays. http://www.physorg.com/news152973325.html Physics Wed, 04 Feb 2009 12:36:20 EST news152973325 President Barack Obama has made his intention of eliminating all nuclear weapons a tenet of his administration's foreign policy.
