SAN FRANCISCO, April 7 (Xinhua) -- Google's Android will become the most popular smartphone operating system worldwide and will account for 49 percent of the market by 2012, IT research and advisory firm Gartner said Thursday.According to Gartner's projections, worldwide smartphone sales will reach 468 million units in 2011, a 57.7 percent increase from 2010.The company predicts that Apple's iOS will remain the second biggest platform worldwide through 2014 although its share will decrease slightly after 2011, on the assumption that "Apple will be interested in maintaining margins rather than pursuing market share by changing its pricing strategy."Microsoft's Windows, driven by its partnership with Nokia, is expected to move into the mid-tier by the end of 2012 and become the third largest in the worldwide ranking by 2013.Some analysts raised doubts on Gartner's forecasts, saying that its assumption on Apple's price strategy contradicts statements by Apple's chief operating officer Tim Cook and the cooperation between Nokia and Microsoft will not have that much of an impact on smartphone market share by 2012.

BEIJING, Feb. 18 (Xinhua) -- China needs to reform funding methods for scientific and technological research in order to boost the nation's innovation capabilities, said officials and researchers attending a conference in Beijing Friday.The management of the government-funded research projects should also be reformed, State Councilor Liu Yandong said at the national conference on science and technology work.Liu stressed that reform, innovation and cooperation should be the keys for China's science and technology work over the next five years, when the government would increase funding for research in new strategic industries, such as new energy, biomedicine and high-end manufacturing.Last year, central and local government spending on science and technology development totaled 380 billion yuan (57.8 billion U.S. dollars), Science and Technology Minister Wan Gang said at the conference.Over the past five years, central government spending on science and technology development had grown by around 20 percent annually.However, some researchers have complained problems in the funding system actually hinder innovation and progress.Inflexibility in the management of government funds allowed researchers little freedom to adapt projects to developments in their fields, said Li Zhenzhen, a researcher at the Institute of Policy and Management under the Chinese Academy of Sciences (CAS).Chen Jie, a research fellow of the CAS' Institute of Microelectronics, said some authorities which oversee the spending of research funds had been rather rigid."In some cases, they are more interested in spending most of the funds on new equipment than scientists," Chen said in an earlier interview with Xinhua. "Without decent pay, it is difficult to attract top scientists to work in China.""Having to solicit and lobby for funding to support the team's research projects leaves me no more than five hours a day for real research," Chen said.Top-level scientific brains are the key to the innovative capability of China, he added.A researcher attending Friday's conference echoed Chen's opinion."China manufactures 65 percent of the world's computers. But to my knowledge, we are still spending about 150 billion U.S. dollars annually to buy computer chips from overseas," the researcher told Xinhua on condition of anonymity.Wan Gang also said imported computer chips cost China more than crude oil purchases last year.But Wan believed that with breakthroughs in frontier areas such as cloning, manned space flight, moon exploration and supercomputers, China could expect a leap in science and technology development in the near future.In October last year, China successfully launched its second lunar probe, Chang'e-2.A month later, Chinese supercomputer Tianhe-1A, which can perform 2.57 quadrillion computing operations a second, was ranked the world's fastest in the TOP500 list compiled by U.S. and European researchers.

BEIJING, Jan. 30 (Xinhua) -- Chinese Vice Premier Li Keqiang Sunday urged scientists to learn from foreign experiences and increase their participation in international cooperation in polar and oceanic exploration.Li made the remarks after meeting with members of China's 27th Chinese Antarctic expedition team, the 22nd oceanic expedition, and scientists working in the country's Antarctic and Arctic stations via video and telephone.Li said many countries nowadays attached great importance to polar and oceanic exploration, and international competition had grown in promoting the peaceful utilization of these resources.Chinese Vice Premier Li Keqiang (R, front) shakes hands with a senior Chinese explorer in Beijing, capital of China, Jan. 30, 2011. Li conveyed Spring Festival greetings while meeting with members of China's 27th Chinese Antarctic expedition team, the 22nd oceanic expedition, and scientists working in the country's Antarctic and Arctic stations via video and telephone on Sunday."We are confident and capable of constantly improving our working conditions to conduct polar and oceanic exploration, and winning the initiative in this sector's future development," Li said.Li said the country would work to promote its marine economy and safeguard marine ecosystems, as well, and make full use of the achievements made in explorations to make reasonable development and utilization of ocean resources.China would also ensure the security of ocean passages, and safeguard its marine rights and interests, the vice premier said.Li also conveyed New Years greetings to the scientists for conducting research away from their homeland and families, and applauded their contribution to the country's progress in polar and oceanic research areas.

LOS ANGELES, March 2 (Xinhua) -- Those who take a nap are more likely to have lower levels of blood pressure despite stress, said a new study in the latest issue of International Journal of Behavioral Medicine available on Wednesday.In the study, researchers at Sarah Conklin of Allegheny College in Meadville, Pennsylvania examined 85 healthy university students, who were divided into two groups, with one group taking an hour- long nap during the day, and the other group having no time to sleep. Both groups were given a mental stress test.The study found that participants in both groups experienced increase in blood pressure and pulse rates when they took the stress test, but the average blood pressure of those who slept for at least 45 minutes was significantly lower after the stress test than it was for those who did not sleep.The researchers drew the conclusion that a daytime nap of at least 45 minutes may help stressed-out people lower their blood pressure and protect their heart."Our findings suggest that daytime sleep may offer cardiovascular benefit by accelerating cardiovascular recovery following mental stressors," the researchers said in the study."Further research is needed to explore the mechanism by which daytime sleep is linked with cardiovascular health and to evaluate daytime sleep as a recuperative and protective practice, especially for individuals with known cardiovascular disease risk and those with suboptimal sleep quality," they added.Sleep deficiency is common in the United States, posing a long- term health threat. On average, Americans get nearly two hours less sleep a night than they did 50 years ago, according to background information provided by the journal.

LOS ANGELES, March 27 (Xinhua) -- Walnuts have a combination of more healthful antioxidants and higher quality antioxidants than any other nut, U.S. researchers have found.Study findings were presented on Sunday at the 241st National Meeting & Exposition of the American Chemical Society (ACS) in Anaheim, Southern California.Nuts contain plenty of high-quality protein that can substitute for meat, vitamins and minerals, dietary fiber, and are dairy- and gluten-free, ACS researchers said in the study.Moreover, nuts contain healthful polyunsaturated and monosaturated fats rather than artery-clogging saturated fat, according to the study.The researchers based their conclusion on analysis of antioxidants in nine different types of nuts: walnuts, almonds, peanuts, pistachios, hazelnuts, Brazil nuts, cashews, macadamias and pecans.They found that walnuts have the highest levels of antioxidants, with plenty of high-quality protein that can substitute for meat, vitamins and minerals, dietary fiber, and are dairy- and gluten-free.The latest study adds more evidence that walnuts are top nuts for heart-healthy antioxidants, the researchers said.Previous studies showed that regular consumption of small amounts of nuts or peanut butter can decrease the risk of heart disease, certain kinds of cancer, gallstones, Type 2 diabetes, and other health problems.But the latest study is the first to compare both the amount and quality of antioxidants found in different nuts."Walnuts rank above peanuts, almonds, pecans, pistachios and other nuts," said Joe Vinson, Ph.D., who led the latest study."A handful of walnuts contains almost twice as much antioxidants as an equivalent amount of any other commonly consumed nut. But unfortunately, people don't eat a lot of them. This study suggests that consumers should eat more walnuts as part of a healthy diet."
