The findings show, among other things, the importance of the country’s military research and the challenges of an underdeveloped healthcare system with a strong faith in traditional Chinese medicine. http://chinese.eurekalert.org/en/pub_releases/2012-05/uu-nss051512.php Tue, 15 May 2012 00:00:00 EDT Researchers have tracked the spread of methicillin-resistant Staphylococcus aureus (MRSA) from hospitals in large population centers in London and Glasgow to regional health care settings, and propose that patient referrals play an important role in transmission in the United Kingdom. http://chinese.eurekalert.org/en/pub_releases/2012-05/aaft-prm051112.php Tue, 15 May 2012 00:00:00 EDT If education lowers death rates, the effect is likely to manifest in late adulthood, not shortly after most people complete their education, a study suggests. Previous research has suggested links between education and life expectancy, but evidence for the notion that longer education leads to better health has remained elusive, partly because of the profusion of confounding factors that surround the seemingly circular relationship between education and health. http://chinese.eurekalert.org/en/pub_releases/2012-05/aaft-ioe051112.php Tue, 15 May 2012 00:00:00 EDT Researchers report the results of a global assessment of the threat that dams pose to fish species. Vulnerable species were defined as those whose life cycle requires migration or that are restricted to a specific region. Regions with high levels of river obstruction and large numbers of vulnerable species were mapped and identified as high-priority candidates for conservation or restoration projects. http://chinese.eurekalert.org/en/pub_releases/2012-05/aiob-rmf051412.php Mon, 14 May 2012 00:00:00 EDT BGI, the world's largest genomics organization, in cooperation with Zhangjiakou Academy of Agricultural Science, has completed the genome sequence and analysis of foxtail millet (Setaria italica), the second-most widely planted species of millet. http://chinese.eurekalert.org/en/pub_releases/2012-05/bs-brt051112.php Mon, 14 May 2012 00:00:00 EDT Coesite has been identified in eclogite and its country rock in the different outcrops, which further suggests the 'in situ' origin of UHP metamorphic belt in southwestern Tianshan, central Asia. http://chinese.eurekalert.org/en/pub_releases/2012-05/sicp-tnp051012.php Sat, 12 May 2012 00:00:00 EDT Existing researchers for the first time mapped the forest carbon sink / source space distribution map (1km) of China to provide better technical support in deal with global warming. The study was published in Chinese Science Bulletin 2012 11. http://chinese.eurekalert.org/en/pub_releases/2012-05/sicp-cfc051012.php Sat, 12 May 2012 00:00:00 EDT A new electronic medical record tool that tallies patients' previous radiation exposure from CT scans helps reduce potentially unnecessary use of the tests among emergency room patients with abdominal pain, according to a study from researchers at the Perelman School of Medicine at the University of Pennsylvania that will be presented today at the annual meeting of the Society for Academic Emergency Medicine. http://chinese.eurekalert.org/en/pub_releases/2012-05/aaft-emr051012.php Sat, 12 May 2012 00:00:00 EDT The fish swimming traces (Undicha undichna) are described in this paper originated from the Lower Triassic Jialingjiang Formation in Emei City, Sichuan Province. The ichnospecies Undicha undichna is reported for the first time from the Triassic Period in the world and presently is the oldest evidence of vertebrate ichnites in China. http://chinese.eurekalert.org/en/pub_releases/2012-05/sicp-fst051012.php Sat, 12 May 2012 00:00:00 EDT The pollution of heavy metals in the water is one of the world widely-concerned environmental problems. A recent study focused on the toxic effects of five heavy metals on the growth and photosynthesis of Chlorella vulgaris in the sub-lethal concentrations, which would provide a theoretical basis for a comprehensive understanding of the toxic effects of heavy metals. http://chinese.eurekalert.org/en/pub_releases/2012-05/sicp-teo051012.php Sat, 12 May 2012 00:00:00 EDT Scientists are reporting a possible link between the use of sunscreen containing a certain ingredient that mimics the effects of the female sex hormone estrogen and an increased risk of being diagnosed with endometriosis, a painful condition in which uterine tissue grows outside the uterus. They describe the report, published in ACS' journal Environmental Science & Technology, as the first to examine whether such a connection may exist. http://chinese.eurekalert.org/en/pub_releases/2012-05/acs-fsi051012.php Fri, 11 May 2012 00:00:00 EDT The sun is moving through interstellar space more slowly than previously thought, and appears to have a weaker interaction with the rest of the galaxy, reports a new study. Our solar system zips through space, traveling inside a bubble of solar wind and magnetic field called the heliosphere. http://chinese.eurekalert.org/en/pub_releases/2012-05/aaft-asw050712.php Fri, 11 May 2012 00:00:00 EDT The number of rare gene variants in the human population has increased as the population size has exploded over the last 10,000 years, researchers report. The findings have implications for genetic models that simulate changes in the human population, as these models are typically based on a relatively small number of fully-sequenced genomes. http://chinese.eurekalert.org/en/pub_releases/2012-05/aaft-mra050712.php Fri, 11 May 2012 00:00:00 EDT An analysis of data provided by the Kepler spacecraft, which has been monitoring the brightness of approximately 150,000 stars and searching for evidence of planets passing in front of them, has led to the discovery of at least one more planet that was not originally identified by the Kepler Team. http://chinese.eurekalert.org/en/pub_releases/2012-05/aaft-tpt050712.php Fri, 11 May 2012 00:00:00 EDT A painted room in a Mayan temple in Guatemala shows numerical records of lunar and possibly planetary cycles, researchers report. The hieroglyphs are from the 9th century, making this calendar several centuries older than those of the Mayan Codices, which were written in bark-paper books. http://chinese.eurekalert.org/en/pub_releases/2012-05/aaft-ekm050712.php Fri, 11 May 2012 00:00:00 EDT Gene therapy may help protect brain cancer patients from the harmful effects of chemotherapy, a new study reports. The strategy should allow patients to receive higher, more effective doses of chemotherapy -- without increasing the risk of dangerous complications like low blood cell counts. A drop in blood cells opens the door for infections, excessive bleeding and other conditions that force many patients to discontinue therapy until cells counts improve. http://chinese.eurekalert.org/en/pub_releases/2012-05/aaft-pbc050712.php Thu, 10 May 2012 00:00:00 EDT An international research team led by Virginia Tech Associate Professor Boris Vinatzer and Giorgio Balestra of the University of Tuscia in Italy has used the latest DNA sequencing technology to trace a devastating pathogen back to its likely origin. http://chinese.eurekalert.org/en/pub_releases/2012-05/aaft-vta050312.php Thu, 10 May 2012 00:00:00 EDT
