WASHINGTON, April 4 (Xinhua) -- Scientists have identified a gene that appears to play a role in regulating how much alcohol people drink, in a study of over 47,000 people published Monday in the Proceedings of the National Academy of Sciences.The researchers say that finding a common genetic variation influencing levels of alcohol consumption may lead to a better understanding of mechanisms underlying alcohol drinking behavior in the general population.The gene, called "autism susceptibility candidate 2", or AUTS2, has previously been linked to autism and attention deficit hyperactivity disorder, but its function is not known.The new study, by an international consortium led by scientists at Imperial College London and King's College London, found that there are two versions of the AUTS2 gene, one three times more common than the other. People with the less common version drink on average five percent less alcohol than people with the more common version.The gene is most active in parts of the brain associated with neuropsychological reward mechanisms, suggesting that it might play a part in regulating the positive reinforcement that people feel when they drink alcohol.Alcohol consumption is known to be partly determined by genes but until now the only gene known to make a notable contribution was the gene encoding alcohol dehydrogenase, an enzyme that breaks down alcohol in the liver.Professor Paul Elliott, from the School of Public Health at Imperial College London, said: "Of course there are a lot of factors that affect how much alcohol a person drinks, but we know from twin studies that genes play an important role. The difference that this particular gene makes is only small, but by finding it we've opened up a new area of research into the biological mechanisms that control drinking."

BEIJING, Jan. 22 (Xinhua) -- Chinese President Hu Jintao has just ended his four-day landmark visit to the United States.During the visit, both sides agreed to build a China-U.S. cooperative partnership based on mutual respect and mutual benefit, which is to lead the development of bilateral ties in the future.It is widely believed that, in the new era, China and the United States need to enhance their political and economic relations, as well as boost cooperation in regional and international affairs.In order to achieve that, observers from across the world hold that the key lies in common actions.BLUEPRINT FOR BILATERAL RELATIONSReiterating their commitment to developing a positive, cooperative and comprehensive China-U.S. relationship as they agreed in 2009, Chinese and U.S. leaders also vowed to build "a cooperative partnership based on mutual respect and mutual benefit", during Hu's visit to Washington.The two terms showed a kind of progress which represented the increasing common interests and mutual need of the two sides over the recent period, as well as more and more challenges that required the joint efforts of the largest developed and developing countries, Chinese Vice Foreign Minister Cui Tiankai said.Yuan Peng, director of the America Studies of China Institute for Contemporary International Relations (CICIR), said the new expression of bilateral ties was positive, objective and pragmatic.As the deepening and development of the previous expression, the new term was a highlight of President Hu's U.S. visit, Yuan said.The joint statement issued by both sides during Hu's stay, which is built upon bilateral efforts to establish the cooperative partnership based on mutual respect and mutual benefit, is a clear reflection of the two countries' resolution and pragmatic attitude in jointly meeting global challenges, according to Chen Kang, professor at Lee Kuan Yew School of Public Policy at the National University of Singapore.In a nutshell, every word matters in the new expression.As "mutual respect" urges both China and the United States to respect each other's core interests and path of development, "mutual benefit" means that both countries are expected to achieve a win-win situation rather than a win-lose one, and bring about common prosperity."Partnership," meanwhile, shows that the two powers, instead of being rivals, are closely linked with each other in actions to cope with regional and international issues.Fu Mengzi, a researcher with the Beijing-based CICIR, told Xinhua, while every country attached great importance to their own national interest, their respective interests were neither unilateral nor absolute."When seeking its own interest, a country should meanwhile take into consideration the interest and major concerns of other countries," Fu said, adding that only by so doing could a win-win result rather than a zero-sum relationship be achieved.

BEIJING, Feb. 18 (Xinhua) -- Jia Qinglin, China's top political advisor, urged the municipality of Beijing to intensify efforts to promote the development of service and manufacturing industries.Jia, chairman of the National Committee of the Chinese People's Political Consultative Conference, made the remarks during his inspection tour in Beijing from Wednesday to Friday.During the tour, Jia visited factories, construction sites and communities to exchange views with officials and civilians. He also listened to a report from the Beijing municipal government.Beijing has taken the lead in optimizing its industrial structure as the output of its service industry accounts for 75 percent of the revenue from all sectors, according to official sources of the city.Jia encouraged Beijing to continue to promote its service sector by focusing on producer services and expanding the city's service businesses overseas.While visiting Beijing Benz Automotive Co., Ltd., Jia called for the strengthening of technological innovation in order to boost high-end equipment manufacturing.Beijing should turn itself into a center for national technological innovation to contribute to the country's economic development, Jia said.He also stressed the better protection of forest resources and the more efficient use of water to develop modern agriculture.
