The researchers reported Nov. 29 in Nature Materials the first demonstration of high-temperature stability in metallic nanoparticles, the vaunted next-generation materials hampered by a vulnerability to extreme heat. http://www.physorg.com/news178810410.html Nanotechnology Mon, 30 Nov 2009 13:34:21 EST news178810410 Scientists are building a clearer image of the machinery employed by bacteria to spread antibiotic resistance or cause diseases such as whooping cough, peptic stomach ulcers and legionnaires' disease. http://www.physorg.com/news178810154.html Biology Mon, 30 Nov 2009 13:29:45 EST news178810154 There is a tiny period of time between the registration of a visual stimulus by the unconscious mind and our conscious recognition of it ― between the time we see an apple and the time we recognize it as an apple. Our minds lag behind our eyes, but by how long? And how does this affect our reactions to the world around us? http://www.physorg.com/news178809676.html Medicine & Health Mon, 30 Nov 2009 13:21:41 EST news178809676 (AP) -- Huge sheets of glass are guided by robotic arms, sliding and turning in a towering germ-free plant, the world's first making giant "10th generation" panels for flat screen TVs. http://www.physorg.com/news178807044.html Technology Mon, 30 Nov 2009 12:50:01 EST news178807044 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 Those extra helpings of gravy and dessert at the holiday table are even less of a help to your waistline than previously thought. According to a new research report recently appearing online in The FASEB Journal, a diet that is high in fat and in sugar actually switches on genes that ultimately cause our bodies to store too much fat. This means these foods hit you with a double-whammy as the already difficult task of converting high-fat and high-sugar foods to energy is made even harder because these foods also turn our bodies into "supersized fat-storing" machines. http://www.physorg.com/news178806891.html Medicine & Health Mon, 30 Nov 2009 12:35:39 EST news178806891 (PhysOrg.com) -- When asked to inhibit their response to a "cocaine-cues" video, active cocaine abusers were, on average, able to suppress activity in brain regions linked to drug craving, according to a new study at the U.S. Department of Energy's Brookhaven National Laboratory. The results, to be published in an upcoming issue of NeuroImage, suggest that clinical interventions designed to strengthen these inhibitory responses could help cocaine abusers stop using drugs and avoid relapse. http://www.physorg.com/news178806768.html Medicine & Health Mon, 30 Nov 2009 12:33:19 EST news178806768 In the film, 'The Day After Tomorrow' the world enters the icy grip of a new glacial period within the space of just a few weeks.

A brand new scenario has emerged from a recent set of outstanding observations of a black hole without a home: black holes may be `building` their own host galaxy. This could be the long-sought missing link to understanding why the masses of black holes are larger in galaxies that contain more stars. http://www.physorg.com/news178804126.html Space & Earth Mon, 30 Nov 2009 11:49:22 EST news178804126 Humans use their whole bodies, not just their ears, to understand speech, according to University of British Columbia linguistics research. http://www.physorg.com/news178803034.html Medicine & Health Mon, 30 Nov 2009 11:31:11 EST news178803034 (PhysOrg.com) -- The findings of a Spanish study claiming that Wikipedia's editors are leaving at an alarming rate have been refuted by the Wikimedia Foundation and by Wikipedia co-founder Jimmy Wales. http://www.physorg.com/news178787309.html Technology Mon, 30 Nov 2009 09:40:01 EST news178787309 (PhysOrg.com) -- While quantum dots have existed since the 1980s, only in the past decade have physicists successfully created lateral few-electron single quantum dots. These quantum dots enable physicists to manipulate quantum spins, which could be used as qubits for quantum information applications. Along these lines, a team of physicists from the National Research Council in Canada who were responsible for the original lateral few-electron single quantum dot have recently designed a new few-electron triple quantum dot circuit, and demonstrated that all three quantum dots can be tuned in resonance. http://www.physorg.com/news178789034.html Nanotechnology Mon, 30 Nov 2009 09:10:01 EST news178789034 (AP) -- There's an intriguing idea floating around the media: Microsoft Corp. wants to undercut Google so badly in Internet search that it might pay newspapers to withhold their content from Google.

A new study has for the first time found that handedness, as seen in the direction of a snail shell spiral, can be reversed by manual manipulation of eight cell stage embryos, which is much earlier than previously thought. http://www.physorg.com/news178786914.html Biology Mon, 30 Nov 2009 07:03:02 EST news178786914 Kangaroos may provide the key to a potential treatment to prevent skin cancer, Australian scientists said Monday. http://www.physorg.com/news178782503.html Medicine & Health Mon, 30 Nov 2009 06:26:17 EST news178782503 Historic manuscripts by Sir Isaac Newton, Benjamin Franklin and other ground-breaking scientists will be published online for the first time, Britain's Royal Society said Monday. http://www.physorg.com/news178782363.html Technology Mon, 30 Nov 2009 05:46:30 EST news178782363 (PhysOrg.com) -- CERN's Large Hadron Collider has today become the world's highest energy particle accelerator, having accelerated its twin beams of protons to an energy of 1.18 TeV in the early hours of the morning.
