SHIJIAZHUANG, Dec. 3 (Xinhua) -- More than 3.48 million people in rural areas of north China's Hebei Province have been given access to safe drinking water this year, a local official said Saturday.Authorities in the province have invested more than 1.7 billion yuan (270 million U.S. dollars) so far in 2011 in building drinking water infrastructure, said Liang Jianyi, deputy director of the Hebei Provincial Department of Water and Resources.More than 32 million rural people in Hebei, especially in mountainous and coastal areas, had long suffered from unsafe water, with problems including high fluorine and alkaline contents, Liang said.From 2005 to 2010, the provincial authorities put almost 6 billion yuan into providing safe drinking water for 13 million rural residents, he added.

SAN FRANCISCO, Nov. 21 (Xinhua) -- E-commerce and online payment giant eBay announced on Monday that it has acquired New York-based technology startup Hunch, an online platform that delivers customized recommendations to users based on their individual tastes.Hunch's team and expertise in areas like machine learning, data mining and predictive modeling are expected to help eBay to integrate more advanced recommendations into its website, said the San Jose, California-based company."Unlike traditional online retail approaches, Hunch will enable eBay to move beyond standard item-to-item recommendations and use a broader variety of members' online tastes and interests to suggest new and interesting items for them to browse and buy on eBay," said the company in a press release.Terms of the deal were not disclosed. Technology news site TechCrunch founder Michael Arrington said in his personal blog prior to the acquisition announcement that eBay would acquire Hunch for 80 million U.S. dollars.Hunch, co-founded by popular photo-sharing service Flickr co- founder Caterina Fake with an 11-person team of MIT graduates, was open to the public in 2009. According to eBay, Hunch's employees will remain with the company in New York.

WASHINGTON, Dec. 5 (Xinhua) -- Young women may reduce their risk of developing cardiovascular disease simply by eating more fish rich in omega-3 fatty acids, researchers reported Monday in Hypertension: Journal of the American Heart Association.In the first population-based study in Danish women of childbearing age, those who rarely or never ate fish had 50 percent more cardiovascular problems over eight years than those who ate fish regularly. Compared to women who ate fish high in omega-3 weekly, the risk was 90 percent higher for those who rarely or never ate fish.About 49,000 women, 15-49 years old, median age of just under 30 years in early pregnancy -- were interviewed by telephone or answered food frequency questionnaires about how much, what types and how often they ate fish, as well as lifestyle and family history questions.Researchers recorded 577 cardiovascular events during the eight- year period, including five cardiovascular deaths in women without any prior diagnosis of the disease. In all, 328 events were due to hypertensive disease, 146 from cerebrovascular disease, and 103 from ischemic heart disease. Inpatient and outpatient admission for cardiovascular disease was much more common among women who reported eating little or no fish. In three different assessments over a 30-week period, women who never ate fish had a three-fold higher disease risk compared to women who ate fish every week."To our knowledge this is the first study of this size to focus exclusively on women of childbearing age," said Marin Strom, lead researcher and post doctoral fellow at the Center for Fetal Programming, at Statens Serum Institute in Copenhagen, Denmark. " We saw a strong association with cardiovascular disease in the women who were still in their late 30's."Fish oil contains long chain omega-3 polyunsaturated fatty acids, which are believed to protect against heart and vascular disease. Few women in the study took fish oil supplements, so these were excluded from the analyses and the results were based on the dietary intake of omega-3 fatty acids, not intake from supplements.The most common fish consumed by women in the study were cod, salmon, herring, and mackerel."Our study shows that for younger women, eating fish is very important for overall health, and even though we found cardio- protective effects at relatively modest dietary levels, higher levels may yield additional benefits," Strom said.

BEIJING Jan. 10 (Xinhuanet) -- Scientists have found a plant in Brazil using leaves to capture the tiny worms in the soil, according to Monday's Proceedings of the National Academy of Sciences in the U.S.The plant, named Philcoxia, was found in the tropical grassland of Brazil, where the biodiversity is well conserved.As the scientists searching for the answer of why the plant grows the leaves underground, they found the 1.5 millimeters-wide leaves can trap the worms and produce a digestive enzyme to help its roots to absorb the nutrition.Although it is not the first meat-eating plant to be discovered, the finding has still "broaden up our perception about plants," according to researcher Rafael Silva Oliveira, a plant ecologist at the State University of Campinas in Brazil.It suggests that carnivorous plants "may have evolved independently more times in plants than previously thought," he added

WASHINGTON, Nov. 8 (Xinhua) -- Children with autism have more brain cells and heavier brains compared to typically developing children, according to a study to be published on Wednesday in the Journal of the American Medical Association.The small, preliminary study provides direct evidence for possible prenatal causes of autism.The prefrontal cortex is involved in various higher order functions such as language and communication, social behavior, mood, and attention. Children who have autism tend to show deficits in such functions.Eric Courchesne, of the University of San Diego School of Medicine Autism Center of Excellence, and colleagues conducted direct counts of brain cells in specific regions of the prefrontal cortex in postmortem brains of seven boys who had autism and six typically developing males, ranging in age from 2-16 years. Most participants had died in accidents, but the researchers did not base their selection on causes of death.The researchers found that children with autism had 67 percent more neurons in the prefrontal cortex and heavier brains for their age compared to typically developing children. Since these neurons are produced before birth, the study's findings suggest that faulty prenatal cell birth or maintenance may be involved in the development of autism. Another possible factor that may contribute to the neuronal excess is a reduction in apoptosis, or programmed cell death, which normally occurs during the third trimester and early postnatal life.Though small, this preliminary study examined all relevant postmortem tissue available at the time. The relative scarcity of tissue from very young children may limit future research as well, but efforts to include a larger number of samples are needed to confirm these findings and to identify patterns of age-related changes in autism, the researchers say."Earlier studies of head circumference and early brain overgrowth have pointed us in this direction, but there have been few quantitative neuroanatomical studies due to the lack of postmortem tissue from children with autism," said Thomas Insel, director of the National Institute of Mental Health, in a statement. "These new results, along with an earlier study reporting altered wiring of the prefrontal cortex, focus our attention on this critical area of the brain in autism."
