BEIJING, Feb. 10 (Xinhua) -- The Chinese currency, or the yuan, on Thursday rose to a fresh high of 6.5849 against the U.S. dollar, according to the China Foreign Exchange Trading System.The central parity rate of the yuan, or RMB, was 1 basis point higher than the previous record of 6.585 set on Feb. 9, the previous trading day.The central parity rate has risen against the dollar for a three consecutive trading days.China's central bank announced on June 19 last year that it would further reform the yuan exchange rate formation mechanism to improve its flexibility.On China's foreign exchange spot market, the yuan can rise or fall 0.5 percent from the central parity rate each trading day.The central parity rate of the RMB against the U.S. dollar is based on a weighted average of prices before the opening of the market each business day.

BEIJING, Feb. 12 (Xinhua) -- Sales revenue of Beijing's auto market in 2011 might shrink by 60 billion yuan (about 9.1 billion U.S. dollars) due to the city limiting the number of cars purchased each month, a commerce official said Saturday.Car sales revenue will drop to 100 billion yuan in 2011 from last year's 160 billion yuan, Wang Shuxia, chief for marketing section with the Beijing Municipal Commission of Commerce, told a working meeting of the commission.A control on car purchases introduced this year limits new car license plates to 240,000 in 2011, said Wang.In 2010, more than 800,000 new cars drove onto Beijing's roads, worsening the chronic gridlock in this Chinese national capital of nearly 5 million automobiles.Wang estimated that Beijing's car sales this year will hit 580,000 units, as some cars will be sold to buyers outside of Beijing while others will be purchased by buyers who are replacing older cars.Car owners who replace their old vehicles can obtain car license plates directly without taking part in the lottery that allots 20,000 new plates each month.

LOS ANGELES, April 6 (Xinhua) -- Freeze-dried strawberries may play a role in the prevention of esophageal cancer, a new study suggests."Strawberries may be an alternative or work together with other chemopreventive drugs for the prevention of esophageal cancer," said lead researcher Tong Chen, M.D., Ph.D., assistant professor, division of medical oncology, department of internal medicine at the Ohio State University.Study findings were presented at the ongoing 102nd annual meeting of the American Association for Cancer Research (AACR) in Orlando, Florida, according to the American Association for the Advancement of Science (AAAS) on Wednesday."We concluded from this study that six months of eating strawberries is safe and easy to consume. In addition, our preliminary data suggests that strawberries can decrease histological grade of precancerous lesions and reduce cancer- related molecular events," said Chen, who is also a member of the Molecular Carcinogenesis and Chemoprevention Program in the Ohio State University Comprehensive Cancer Center.The study involved a group of participants who consumed 60 grams of freeze-dried strawberries daily for six months and completed a dietary diary chronicling their strawberry consumption.The researchers obtained biopsy specimens before and after strawberry consumption. The results showed that 29 out of 36 participants experienced a decrease in histological grade of the precancerous lesions during the study.Using freeze-dried strawberries was important because by removing the water from the berries, they concentrated the preventive substances by nearly 10-fold, Chen said.Esophageal cancer is the third most common gastrointestinal cancer and the sixth most frequent cause of cancer death in the world, she noted.Chen and her team are studying esophageal squamous cell carcinoma (SCC) which makes up 95 percent of cases of esophageal cancer worldwide. China, where this study took place, has the highest incidence of esophageal SCC, according to the AAAS.In a previous study, Chen and colleagues found that freeze- dried strawberries significantly inhibited tumor development in the esophagus of rats. Based on these results, they embarked on a Phase Ib trial that included participants with esophageal precancerous lesions who were at high risk for esophageal cancer."Our study is important because it shows that strawberries may slow the progression of precancerous lesion in the esophagus," Chen said.But she said they need to test this in randomized placebo- controlled trials in the future.

WASHINGTON, March 30 (Xinhua) -- A trace amount of radioactive iodine has been found in a sample of milk from the west state of Washington, the U.S. Environmental Protection Agency and the Food and Drug Administration (FDA) said Wednesday.According to a joint statement from the two agencies, results from a screening sample taken March 25 from Washington detected 0.8 pCi/L of iodine-131, which is more than 5,000 times lower than the Derived Intervention Level set by the FDA.These types of findings are to be expected in the coming days and are far below levels of public health concern, including for infants and children, the statement said.Iodine-131 has a very short half-life of approximately eight days, and the level detected in milk and milk products is therefore expected to drop relatively quickly."Radiation is all around us in our daily lives, and these findings are a minuscule amount compared to what people experience every day. For example, a person would be exposed to low levels of radiation on a round trip cross country flight, watching television, and even from construction materials," said Patricia Hansen, an FDA senior scientist.

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.
