If you ever thought the stress of seeing your extended family over the holidays was slowly killing you -- bad news: a new research report in the December 2009 print issue of the Journal of Leukocyte Biology shows that you might be right. Here's the good news: results from the same study might lead to entirely new treatments that help keep autoimmune diseases like lupus, arthritis, and eczema under control. http://www.physorg.com/news178802608.html Medicine & Health Mon, 30 Nov 2009 11:23:54 EST news178802608 A major obstacle to HIV research is the virus's exquisite specialisation for its human host - meaning that scientists' traditional tools, like the humble lab mouse, can deliver only limited information. Now, a team of researchers writing in BioMed Central's open access Journal of Biology have made an ingenious assault on this problem by creating a mouse that has key features of HIV infection without being infected with HIV. http://www.physorg.com/news178801590.html Medicine & Health Mon, 30 Nov 2009 11:20:01 EST news178801590 (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 Elastography is an effective, convenient technique that, when added to breast ultrasound, helps distinguish cancerous breast lesions from benign results, according to an ongoing study presented today at the annual meeting of the Radiological Society of North America (RSNA). http://www.physorg.com/news178786052.html Medicine & Health Mon, 30 Nov 2009 08:50:02 EST news178786052 (PhysOrg.com) -- The first analysis of immunity-related genes in a solitary bee has been conducted by Agricultural Research Service (ARS) scientists and cooperators. http://www.physorg.com/news178792830.html Biology Mon, 30 Nov 2009 08:50:01 EST news178792830 Every Friday afternoon, the Singapore-MIT GAMBIT Game Lab opens its doors to anyone who wishes to drop by and play. On one such recent day, Jason Begy, a graduate student in the Comparative Media Studies program and a GAMBIT researcher, greeted a visitor from the MIT News Office before offering him tea and a place to hang his coat. http://www.physorg.com/news178792685.html Technology Mon, 30 Nov 2009 08:38:50 EST news178792685 (PhysOrg.com) -- Applying sunscreen on a regular basis not only prevents cancer, but will save the government money. http://www.physorg.com/news178789614.html Medicine & Health Mon, 30 Nov 2009 07:51:44 EST news178789614 Southern Illinois University researchers determined Medicare beneficiaries living in rural areas were 27% more likely than urban recipients to have total knee or hip replacement surgeries. Researchers found women were more likely than men to undergo total joint replacement surgeries. Differences in elective joint surgeries between white individuals and minorities in both rural and urban areas were observed, but were less pronounced in rural settings. Full findings appear in the in the December issue of Arthritis & Rheumatism, a journal published by Wiley-Blackwell on behalf of the American College of Rheumatology. http://www.physorg.com/news178786083.html Medicine & Health Mon, 30 Nov 2009 07:50:01 EST news178786083 (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. Just don't count on that turning into a lucrative plan for newspapers. http://www.physorg.com/news178784890.html Technology Mon, 30 Nov 2009 07:20:01 EST news178784890 (PhysOrg.com) -- In structural biology, the only technique available to predict the three dimensional structure of large complex molecules in solution, such as proteins and DNA, is NMR spectroscopy. To catalyze improvements in the techniques behind these predictions, the "eNMR" project has launched a new initiative. In September`s Nature Methods the project issued an invitation to the entire biomolecular Nuclear Magnetic Resonance community to participate in a large scale test of modern computing algorithms. This community-wide `contest` will potentially improve efficiency, reproducibility and reliability of NMR structure determination. eNMR will be using the Enabling Grids for E-sciencE infrastructure to power their analysis. http://www.physorg.com/news178785696.html Chemistry Mon, 30 Nov 2009 07:10:01 EST news178785696 (PhysOrg.com) -- Like most animals, snails have either left- or right-handed asymmetry (chirality), both internally and externally, and the handedness is hereditary. 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 A recent study suggests that increasing patient responsibility for making medical decisions may decrease their willingness to accept risky treatment options. Details of this proof-of-concept study appear in the December issue of Arthritis Care & Research, a journal published by Wiley-Blackwell on behalf of the American College of Rheumatology. http://www.physorg.com/news178785076.html Medicine & Health Mon, 30 Nov 2009 06:31:42 EST news178785076 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 (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. This exceeds the previous world record of 0.98 TeV, which had been held by the US Fermi National Accelerator Laboratory`s Tevatron collider since 2001. It marks another important milestone on the road to first physics at the LHC in 2010. http://www.physorg.com/news178781372.html Physics Mon, 30 Nov 2009 05:44:16 EST news178781372
