BEIJING, Jan. 26 (Xinhua) -- Chinese Premier Wen Jiabao Wednesday invited more foreign talents to continue their careers or start businesses in China, pledging better conditions for them.During a seminar with more than 20 veteran foreign experts at the Great Hall of the People a week before the Chinese New Year, Wen thanked the foreign friends for their contributions to China's achievements in 2010.Wen said 2011 is a new starting point for China's modernization, as the country implements its 12th five-year plan for economic and social development."China's development is much more associated with the world and the supply of talents than before," Wen said, adding that China will adopt a more open policy to attract overseas experts.Last year, foreign experts made more than 300,000 visits to China, according to Ji Yunshi, general director of the State Administration of Foreign Experts Affairs.

LOS ANGELES, May 15 (Xinhua) -- Using a simple, minimally- invasive technique to analyze cells from the interior of the nose, U.S. researchers have detected lung cancer in its earliest stage.For the study, the researchers at the Boston University Medical Center collected nasal epithelial cells from thirty three smokers who were undergoing medically-indicated bronchoscopies for suspicion of lung cancer, according to the American Association for the Advancement of Science (AAAS) on Sunday.Of these patients, 11 were found to have benign disease and 22 had lung cancer. Brushings were taken from the right or left nostril and profiled on microarrays, a process that allows researchers to study gene expression changes.The researchers identified 170 genes that were differentially expressed between patients with and without lung cancer. They also found that genes linked to colon cancer and adenocarcinoma, as well as genes that trigger cell division and blood vessel growth, were expressed more heavily in patients with cancer. Genes involved in tumor suppression were also expressed at lower levels in these patients.Earlier studies have used gene expression differences in the bronchial airways to identify lung cancer in its early stages. The researchers relied on those results to design the current study."In this study we used the same principle as we used in our earlier studies of bronchial tissue, only this time, those methods were used to study nasal cells," said study author Christina Anderlind, MD, Instructor of Medicine. "Our hypothesis was that the upper airway epithelium of smokers with lung cancer displays a cancer-specific gene expression pattern, and that this airway nasal gene expression signature reflects the changes that occur in lung tissue."

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, Jan. 25 (Xinhua) -- A senior Chinese official has encouraged the country's young jurists to more actively participate in the country's legislative process and better serve the practice of law enforcement.Zhou Yongkang, a member of the Standing Committee of the Political Bureau of the Communist Party of China (CPC) Central Committee, made the remarks in meeting with outstanding youth law science experts on Tuesday in Beijing.Zhou said young experts on law science should pay more attention to practical problems in China's legal construction and propose more insights, advice and suggestions.Young experts should study more problems encountered by common people and better serve the people with their knowledge, Zhou said.Ten experts on law science from the Renmin University of China, China University of Political Science and Law and other universities and Chinese Academy of Social Sciences were awarded the honor of national outstanding young jurists by the China Law Society.
