SAN FRANCISCO, April 5 (Xinhua) -- The appeal of tablet computer and electronic-book reader (e-reader) has been giving a boost to semiconductor market as sales of chips for such devices surged in 2010 and keeps growing, market research firm International Data Corp. (IDC) said on Tuesday.A new IDC report showed that worldwide revenues for media tablet and e-reader semiconductors grew by over 2,000 percent to 3. 3 billion U.S. dollars in 2010 as semiconductor suppliers enabled original equipment manufacturers to bring new products to market less than 8 months after Apple Inc. launched its iPad tablet.According to IDC's definition, media tablets are devices with color displays larger than 5-inch and smaller than 14-inch, running lightweight operating systems and able to be based on either x86 or ARM processors."The opportunity for semiconductors in media tablets and e- readers has exploded and semiconductor suppliers are scrambling to bring to market semiconductor and software platforms to enable these products," Michael Palma, a senior research analyst at IDC, said in a statement.Looking forward, IDC said it expects media tablet and e-reader semiconductor revenues to grow by 120 percent year over year in 2011, predicting that the market will be boosted by the arrival of a new version of Google Inc.'s Android operating system, dual core processors and increased bandwidth."For the next several years, we will see rapid innovation cycles for products launched into the marketplace and semiconductor suppliers will continue to satisfy evolving end user requirements over the coming years," Palma noted.

LOS ANGELES, May 6 (Xinhua) -- Limiting prolonged bottle use in children may be an effective way to help prevent obesity, a new study suggests.For the study, researchers from the Center for Obesity Research and Education at Temple University (CORETU) and the Ohio State University College of Public Health analyzed data from 6,750 children to estimate the association between bottle use at 24 months of age and the risk of obesity at 5.5 years of age, according to the Science Daily on Friday.Of the children studied, 22 percent were prolonged bottle users, meaning that at two years of age they used a bottle as their primary drink container and/or were put to bed with a calorie- containing bottle.The findings showed that nearly 23 percent of the prolonged bottle users were obese by the time they were 5.5 years old."Children who were still using a bottle at 24 months were approximately 30 percent more likely to be obese at 5.5 years, even after accounting for other factors such as the mother's weight, the child's birth weight, and feeding practices during infancy," said Dr. Robert Whitaker at CORETU, lead author of the study.Drinking from a bottle beyond infancy may contribute to obesity by encouraging the child to consume too many calories, the researchers noted."A 24-month-old girl of average weight and height who is put to bed with an eight-ounce bottle of whole milk would receive approximately 12 percent of her daily caloric needs from that bottle," explained co-author Rachel Gooze.Gooze noted that weaning children from the bottle by the time they are one year of age is unlikely to cause harm and may prevent obesity. The authors suggested that pediatricians and other health professionals work with parents to find acceptable solutions for stopping bottle use at the child's first birthday.The findings adds new evidence to the theory that obesity prevention should begin before children enter school, the researchers said.

BEIJING, Feb. 10 (Xinhua) -- First snow fell in Beijing Wednesday night and continued into Thursday morning. It was the latest first snow for the city in 60 years.Beijing has had no precipitation for 108 consecutive days this winter.Local meteorologists said from 8:00 Wednesday to 6:00 Thursday, precipitation in Beijing averaged 1 mm."Now there is snow at last. I love the taste of snow." "The world in pure white! It's the most beautiful landscape in winter." Beijing residents who stayed late in the night and happened to see the first flakes of snow in the city left their postings on microblogs.However, meteorologists said the first snow won't last long and it will end on Thursday noon. In midnight, the city will have a cloudy weather, and Friday will be a sunny day."As the precipitation is small, it will have limited effect on easing drought," Song Jisong, the municipal meteorological bureau's chief weather forecaster said.Sun said that the capital city's record-long winter drought occurred in the winter of 1970/71, when there was no precipitation for 114 days. This winter drought was the second longest in 60 years.Meteorologists said the current snowfall will reduce risks of fire.The snow also affected the city's traffic. Local traffic control authorities estimated that there were more than 40 highways on which vehicles ran at a speed lower than 20 km per hour in the rush hour Thursday morning.The authorities said an emergency headquarters had been set up for the snow weather. Expressways connecting Beijing with Chengde, Tianjin and Tibet will likely have some sections closed for the time being.A spokesperson with the Beijing Capital International Airport Co., Ltd. said that by 6:00 a.m. Thursday, runways at the airport had operated normally, and take-offs and landings had been normal, with no flights delayed.The airport has also launched an emergency scheme. At last 64 ice removal vehicles had been arranged to ensure the normal operaton of flights.Wednesday also saw snowfall and sleet in Gansu, Shaanxi, Shanxi, Henan and Anhui provinces and rainfall in the Yellow River and Huaihe River valleys, southwestern regions and the middle-and-lower reaches of the Yangtze River valley. And snow and rainfall will continue in the those areas Thursday.

BEIJING, March 19 (Xinhua) -- In spite of the fact that snow still covers his farmland, Jiang Chen has been busy stocking fertilizers and seeds to prepare for the coming spring farming season."I am almost ready for the sowing," said Jiang, a 64-year-old peasant who farms five hectares of cropland in Liujia Township in Yushu City, northeast China's Jilin Province. "But the costs are rising so I still want to look for better seeds providing a higher yield this year."As the Chinese government continued policies to assure a good grain harvest this year, millions of farmers like Jiang in China's major grain-producing regions such as Jilin, Heilongjiang, Shandong and Henan provinces are now gearing up to finalize preparations for the coming sowing season.The central government's incentives in 2011 include increases in minimum rice purchase prices by 9.7 percent to 21.9 percent from last year, as well as 24.9 billion yuan (about 3.77 billion U.S. dollars) in subsidies to the national grain risk fund for farmers."Though farmers are richer now than before, our economic strength remains relatively weak as compared with urban residents," Jiang said.He noted that he was considering investing less this year because the cost of agricultural production has increased year after year.The average urea price from manufacturers and retailers rose about 10 percent from last year to about 1,980 yuan and 2,100 yuan per tonne at a grain and oil wholesale market near Yuquan Road in Beijing, where many farmers from neighboring Hebei, Henan and Shandong provinces buy agricultural fertilizers and additives.Urea is the primary fertilizer used by Chinese grain growers, though many of the farmers said that they would reduce the use the compound in their fields due to rising prices and the impact on wheat caused by the widespread drought in north China this winter.Wang Quan, the president of China National Agricultural Means of Production Group Corp., the country's largest supplier of agricultural materials, predicted that the use of urea during the spring farming season would be between 20 million tonnes to 25 million tonnes, which is about two fifths of the year's total.Wang said that the urea price is around 400 U.S. dollars per tonne in global markets, or 15.7 percent higher than the domestic price."I think it takes time for Chinese farmers to accept the price hikes gradually," he added.Analysts say that the different perceptions on urea prices between manufacturers and farmers may have affected China's crops because the reduced use of fertilizers usually mean less grain output in the country since many farmers depend more on fertilizers, rather than technology to boost production.China's grain output rose 2.9 percent last year to 546.41 million tonnes, marking the seventh consecutive year of growth. The country aims to keep its 2011 grain production over 500 million tonnes, according to an executive meeting of the State Council, or the Cabinet, Thursday.Chinese Premier Wen Jiabao said last month that rising costs of grain production, the lingering drought in north China's major wheat-growing regions and the weakening of agricultural production in some areas would directly affect China's summer grain output.Facing challenges such as higher costs for growing grain, Jiang believed that he could generate higher income from his crops this year with the support of the agricultural sector by the government."If the grain prices also rise this year, I can still earn a net income of 10,000 yuan for every hectare of farmland," Jiang said."I hope to keep my farmland from being seized for industrial or residential development," he added.

LOS ANGELES, May 12 (Xinhua) -- A subsurface ocean of molten or partially molten magma exists beneath the surface of Jupiter's volcanic moon Io, the Jet Propulsion Laboratory (JPL) said on Thursday."The finding heralds the first direct confirmation of this kind of magma layer at Io and explains why the moon is the most volcanic object known in the solar system," JPL said in a press release posted on its website.The finding was based on new data analysis from NASA's Galileo spacecraft, said JPL.The research was conducted by scientists at the University of California, Los Angeles; the University of California, Santa Cruz;, and the University of Michigan, Ann Arbor. The study is published this week in the journal Science, JPL said."Scientists are excited we finally understand where Io's magma is coming from and have an explanation for some of the mysterious signatures we saw in some of the Galileo's magnetic field data," said Krishan Khurana, lead author of the study and former co- investigator on Galileo's magnetometer team at UCLA."It turns out Io was continually giving off a 'sounding signal' in Jupiter's rotating magnetic field that matched what would be expected from molten or partially molten rocks deep beneath the surface."Io produces about 100 times more lava each year than all the volcanoes on Earth, according to data released by JPL in Pasadena, Los Angeles.While Earth's volcanoes occur in localized hotspots like the "Ring of Fire" around the Pacific Ocean, Io's volcanoes are distributed all over its surface, JPL said, adding that a global magma ocean about 30 to 50 km beneath Io's crust helps explain the moon's activity."It has been suggested that both the Earth and its moon may have had similar magma oceans billions of years ago at the time of their formation, but they have long since cooled," said Torrence Johnson, a former Galileo project scientist based at JPL, an affiliation with NASA."Io's volcanism informs us how volcanoes work and provides a window in time to styles of volcanic activity that may have occurred on the Earth and moon during their earliest history," said Johnson, who was not directly involved in the study.NASA's Voyager spacecraft discovered Io's volcanoes in 1979, making that moon the only body in the solar system other than Earth known to have active magma volcanoes. The energy for the volcanic activity comes from the squeezing and stretching of the moon by Jupiter's gravity as Io orbits the largest planet in the solar system.Galileo was launched in 1989 and began orbiting Jupiter in 1995. Unexplained signatures appeared in magnetic field data from Galileo flybys of Io in October 1999 and February 2000. After a successful mission, the spacecraft was intentionally sent into Jupiter's atmosphere in 2003.
