WASHINGTON, Jan. 1 (Xinhua) -- Twin U.S. spacecraft to study the moon from crust to core put themselves into the lunar orbit on New Year's Eve and New Year's Day, the country's space agency said.The second Gravity Recovery And Interior Laboratory, or GRAIL-B, reached its lunar orbit at 5:43 p.m. EST (2243 GMT) on Sunday, according to the National Aeronautics and Space Administration (NASA).The GRAIL-A started orbiting the moon at 5 p.m. (2200 GMT) Saturday.The insertion maneuvers placed the spacecraft into a near-polar, elliptical orbit with an orbital period of approximately 11.5 hours, NASA said.Over the coming weeks, the GRAIL team will execute a series of burns with each spacecraft to reduce their orbital period to just under two hours. At the start of the science phase in March 2012, the twin GRAILs will be in a near-polar, near-circular orbit with an altitude of about 55 km."NASA greets the new year with a new mission of exploration," Administrator Charles Bolden said in a statement. "The twin GRAIL spacecraft will vastly expand our knowledge of our moon and the evolution of our own planet."During GRAIL's science mission, the two probes will transmit radio signals precisely defining the distance between them. As they fly over areas of greater and lesser gravity caused by visible features such as mountains, craters and masses hidden beneath the lunar surface, the distance between the twin spacecraft will change slightly.Scientists will translate this information into a high-resolution map of the moon's gravitational field.The data will allow scientists to understand what goes on below the lunar surface and increase knowledge of how Earth and its rocky neighbors in the inner solar system developed into the diverse worlds we see today.

BEIJING, Dec. 4 (Xinhua) - Orthopaedic experts have warned that China should improve its prevention of orthopaedic illnesses as its population ages.Osteoporosis, bone fractures and joint diseases, to which elderly people are particularly susceptible, have surged as serious health concerns, said Feng Huicheng, surgeon-in-chief of a leading Chinese orthopaedics hospital, at the Sixth International Congress of the Chinese Orthopaedic Association (COA) Sunday in Beijing.According to China's latest census in 2010, the number of people aged 60 and over stood at 177.65 million and accounted for more than 13 percent of the country's total 1.3 billion population."Orthopaedic diseases pose a great threat to the elderly, and they'll only grow more serious as we have a large population that is aging," said Dr. Feng from the No. 309 Hospital of the People's Liberation Army."The younger generation should start to be concerned with their health now, particularly calcium loss, to prevent osteoporosis when getting old.".A report issued by the International Osteoporosis Foundation this year shows that about 70 million people in China now suffer from the condition and that number may leap to 286 million by 2020.H.K.T.Raza, president of the Asia Pacific Orthopaedic Association, said at the conference that the prevention of osteoporosis should begin when people are still young."Osteoporosis is best prevented by regular exercises and good dietary controls. All that has to be done early in life, maybe between 20 and 30, to prevent the disease," he said.According to the World Health Organization, osteoporosis remains one of the primary threats to the health of the middle-aged and elderly.Osteoporosis is the thinning of bone tissue and loss of bone density over time. Parts of the bone grow weak and prone to fracture. Women are usually subject to greater risk of osteoporosis than men as they start with lower bone density and lose bone mass faster as they age. 

WASHINGTON, Nov. 29 (Xinhua) -- China and the United States on Tuesday held high-level talks on enhancing cooperation on anti- monopoly and anti-trust enforcement, with an aim to strengthen the bilateral economic and trade relations.This was the first time that the two sides held such meeting since they signed in last July a memorandum of understanding (MOU) on anti-monopoly and anti-trust enforcement cooperation by related enforcement agencies from the two countries.Gao Hucheng, China's International Trade Representative and Vice Minister of the Ministry of Commerce, led the Chinese delegation to the talks with the U.S. delegation headed by Jon Leibowitz, chairman of the U.S. Federal Trade Commission, and Sharis Pozen, acting Assistant Attorney General of the Department of Justice in charge of anti-trust affairs.The two sides briefed each other on the latest developments on the anti-monopoly and anti-trust policies and their enforcement in own country, while discussing ways to further strengthen anti- monopoly and anti-trust enforcement in related industries, during a time of economic downturn.They also reached an agreement on the guidelines of cooperation on pursuing anti-monopoly and anti-trust enforcement in individual cases, such as mergers of corporations, after reviewing the bilateral exchanges and cooperation in this field.It was agreed that the China-U.S. economic and trade relations are the cornerstone of the overall bilateral relationship, and the enforcement of anti-monopoly and anti-trust laws can help secure the smooth development of their economies, to the benefits of both countries and peoples.Such talks are conducive to enhancing mutual understanding of each other's practices in formulating and enforcing anti-monopoly and anti-trust policies, through sharing experiences and increased cooperation, the two sides agreed.In July, three Chinese anti-monopoly law enforcement agencies, the National Development and Reform Commission, Ministry of Commerce and State Administration for Industry and Commerce, signed the MOU on cooperation in anti-monopoly and anti-trust enforcement, with the U.S. Department of Justice and Federal Trade Commission.The document is a long-term framework between China's anti- monopoly enforcement agencies and their U.S. counterparts, designed to promote better enforcement of competition laws and regulations of the two countries. Under the MOU, the two sides will hold high-level consultations, exchange of information on law enforcement and policies, as well as cooperation on specific cases, mainly for mergers.
