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."

LOS ANGELES, March 16 (Xinhua) -- The death rate in the United States reached an all-time low in 2009, dropping 2.3 percent from 2008, a newly released report said.This was the 10th straight year of decline, demonstrating that Americans are living longer than ever, according to the report from the U.S. Centers for Disease Control and Prevention's National Center for Health Statistics.The nation saw a drop from 758.7 deaths per 100,000 people in 2008 to 741 per 100,000 people in 2009 when 2,436,682 deaths were reported, said the report published by HealthDay News on Wednesday.However, life expectancy for blacks remained unchanged -- 70.9 years for men and 77.4 years for women. The disparity between whites and blacks is now 4.3 years, representing a 0.2 percent increase from 2008 to 2009, the report found.The report said that deaths fell in 10 of the 15 leading causes of death -- heart disease dropped 3.7 percent, cancer fell 1.1 percent, and stroke declined 4.2 percent.Deaths from Alzheimer's disease, diabetes, chronic lower respiratory diseases and accidents all declined 4.1 percent, according to the report.Deaths from flu and pneumonia fell 4.7 percent, and deaths from septicemia, a bacterial infection, decreased 1.8 percent, the report said.Deaths from homicides fell 6.8 percent, but suicides increased from 35,933 in 2008 to 36,547 in 2009. Other than suicide, which overtook septicemia as the 10th leading cause of death, the ranking of the leading causes of death was unchanged from 2008 to 2009, the report noted.Infant mortality hit a record low in 2009, falling from 6.59 deaths per 1,000 births in 2008 to 6.42, representing a 2.6 percent decrease, according to the report.The report, however, did not give reasons for these trends.Experts think behavioral changes, particularly the decline in smoking, are partly responsible for the improvements.The report's lead author Kenneth Kochanek, a statistician at the center, said this is preliminary data, and the final data, which should be available this summer, may shed some light on the findings.

BEIJING, Jan. 29 (Xinhua) -- Chinese State Councilor Dai Bingguo and U.S. National Security Advisor Tom Donilon on Saturday both spoke highly of Chinese President Hu Jintao's state visit to the United States earlier this month.During a phone conversation, Dai and Donilon agreed that China and the United States should make joint efforts to properly implement the consensus reached by leaders on both sides and cement the achievements made during Hu's visit, which was on Jan. 18-21.They also said that the two sides should maintain the current momentum in the development of bilateral ties and devote themselves to building a cooperative partnership based on mutual respect and mutual benefit.

BEIJING, Feb. 1 (Xinhua) -- Senior Chinese official Zhou Yongkang Tuesday called on law enforcement personnel to take more preventive measures against crime and accidents during the Lunar New Year holiday.Zhou, a Standing Committee member of the Political Bureau of the Communist Party of China (CPC) Central Committee, visited community security personnel, a district court, and police patrolling downtown Beijing Tuesday.He also visited a police station that is responsible for keeping public order in the area surrounding the central leadership compound of Zhongnanhai.During his visits, Zhou, who also heads the Commission for Political and Legal Affairs of the CPC Central Committee, said China was seeing the travel peak for the Spring Festival and some regions were suffering icy weather and lingering drought.He asked the police to take effective measures in traffic control and fire-fighting work, and maintain social order during the holiday season.He commended the practice of deploying special police to patrol the surrounding areas of the Tiananmen Square in central Beijing, saying it could deter crime and enable quick responses to emergencies.During his visit to the district court, Zhou warned there were still "many social conflicts."He asked local courts to solve social conflicts more effectively, promote innovative social management and law enforcement in a just and clean manner.The Spring Festival, or Chinese lunar New Year, is the most important festival for Chinese. It falls on Feb. 3 this year.

MOSCOW, Jan. 24 (Xinhua) -- China and Russia held the fifth round of strategic security talks here Monday, pledging more joint efforts to strengthen national, regional and international security.The Chinese delegation, led by Chinese State Councilor Dai Bingguo, was visiting Russia at the invitation of Russian Security Council Secretary Nikolai Patrushev.During the talks, the two parties exchanged views on major international issues and the further development of strategic partnership and interaction between Russia and China.Both sides agreed that their close bilateral cooperation on global issues has helped maintain regional and world peace, safety and stability.The two countries acknowledged that in order to further enhance strategic mutual trust and improve the security situation around the global, the two sides should chart the development of Sino- Russian relations for the next 10 years from a strategic and comprehensive perspective.As long-time strategic partners, Russia and China will adhere to the principles of mutual trust, win-win cooperation and good neighborliness while conducting strategic coordination, the two sides pledged.The fourth round of Sino-Russian security consultations took place in Beijing in December 2009, when Russia and China signed a protocol on cooperation in the strategic security sphere. The next round of talks is scheduled to be held later this year in China.
