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.

LOS ANGELES, May 1 (Xinhua) -- Middle-aged adults who sleep too less or too much may be more likely to suffer cognitive decline, a new study suggests.According to the study, less than six hours of sleep each night is considered too little and more than eight hours as too much for middle-aged adults.The study, conducted by researchers at University College London Medical School, was published May 1 in the American medical journal Sleep.The researchers conducted the study in two periods -- the 1997- 1999 period and the 2003-2004 period. The participants were asked how many hours they slept on an average week night, and were asked the same question in 2003-2004 after an average 5.4 years of follow-up.The researchers compared those who reported changes in their sleep patterns with people whose sleep duration stayed the same over the course of the study.In the follow-up, each individual was given a battery of standard tests to assess his or her memory, reasoning, vocabulary, global cognitive status and verbal fluency.The study findings show that women who slept seven hours per night had the highest score for every cognitive measure, followed by those who had six hours of sleep. For men, cognitive function was similar for those who reported sleeping six, seven or eight hours.However, less than six hours of sleep -- or more than eight hours -- were associated with lower scores."Sleep provides the body with its daily need for physiological restitution and recovery," explained Jane Ferrie, a senior research fellow in the department of epidemiology and public health at the school. "While seven hours a night appears to be optimal for the majority of human beings, many people can function perfectly well on regular sleep of less or more hours."However, since most research has focused on the effects of sleep deprivation on biological systems, it is not yet fully understood why seven hours is optimal -- or why long sleeping appears to be detrimental, Ferrie said."Chronic short sleep produces hormones and chemicals in the body which increase the risk of developing heart disease and strokes, and other conditions like high blood pressure and cholesterol, diabetes and obesity," she added.

WELLINGTON, May 27 (Xinhua) -- Eating kiwifruit might be a much better way of getting vitamin C into your system than taking purified vitamin supplements, according to research from New Zealand.Researchers with the University of Otago found that in mice eating kiwifruit, vitamin C uptake was five times as effective as taking a purified supplement form.The study was published in the American Journal of Clinical Nutrition, the highest ranking journal for human nutrition research, said a statement from the university.Lead researcher Associate Professor Margreet Vissers said people required vitamin C (ascorbate) in all body tissues and organs to be healthy, but the only source of vitamin C was through food or in purified form, arguably the most commonly consumed vitamin supplement.In the experiment vitamin C-deficient mice were fed the vitamin over a month, either as kiwifruit or as an equivalent amount of pure vitamin C, said the statement.Mice fed the kiwifruit absorbed vitamin C much more efficiently than those given the purified supplement form, and they also retained it for longer, indicating something in the fruit improved absorption and retention."The findings of the mouse trial have important implications for human nutrition," said Vissers."The question that has often been asked is whether a supplement is as good a source of vitamin C as whole foods, but few studies have addressed this issue. We are uniquely placed to do that work. "An equivalent human study was underway to determine whether the situation also applied to people, said the statement.The mouse study was funded by the university and kiwifruit marketing firm Zespri.
