LOS ANGELES, May 6 (Xinhua) -- Limiting prolonged bottle use in children may be an effective way to help prevent obesity, a new study suggests.For the study, researchers from the Center for Obesity Research and Education at Temple University (CORETU) and the Ohio State University College of Public Health analyzed data from 6,750 children to estimate the association between bottle use at 24 months of age and the risk of obesity at 5.5 years of age, according to the Science Daily on Friday.Of the children studied, 22 percent were prolonged bottle users, meaning that at two years of age they used a bottle as their primary drink container and/or were put to bed with a calorie- containing bottle.The findings showed that nearly 23 percent of the prolonged bottle users were obese by the time they were 5.5 years old."Children who were still using a bottle at 24 months were approximately 30 percent more likely to be obese at 5.5 years, even after accounting for other factors such as the mother's weight, the child's birth weight, and feeding practices during infancy," said Dr. Robert Whitaker at CORETU, lead author of the study.Drinking from a bottle beyond infancy may contribute to obesity by encouraging the child to consume too many calories, the researchers noted."A 24-month-old girl of average weight and height who is put to bed with an eight-ounce bottle of whole milk would receive approximately 12 percent of her daily caloric needs from that bottle," explained co-author Rachel Gooze.Gooze noted that weaning children from the bottle by the time they are one year of age is unlikely to cause harm and may prevent obesity. The authors suggested that pediatricians and other health professionals work with parents to find acceptable solutions for stopping bottle use at the child's first birthday.The findings adds new evidence to the theory that obesity prevention should begin before children enter school, the researchers said.

WASHINGTON, May 4 (Xinhua) -- The U.S. National Aeronautics and Space Administration (NASA) announced Wednesday that its Gravity Probe B (GP-B) mission has confirmed two key predictions derived from Albert Einstein's general theory of relativity, which the spacecraft was designed to test.The experiment, launched in 2004, used four ultra-precise gyroscopes to measure the hypothesized geodetic effect, the warping of space and time around a gravitational body, and frame- dragging, the amount a spinning object pulls space and time with it as it rotates.GP-B determined both effects with unprecedented precision by pointing at a single star, IM Pegasi, while in a polar orbit around Earth. If gravity did not affect space and time, GP-B's gyroscopes would point in the same direction forever while in orbit. But in confirmation of Einstein's theories, the gyroscopes experienced measurable, minute changes in the direction of their spin, while Earth's gravity pulled at them.The findings are available online in the journal Physical Review Letters."Imagine the Earth as if it were immersed in honey. As the planet rotates, the honey around it would swirl, and it's the same with space and time," said Francis Everitt, GP-B principal investigator at Stanford University. "GP-B confirmed two of the most profound predictions of Einstein's universe, having far- reaching implications across astrophysics research."GP-B is one of the longest running projects in NASA history, with agency involvement starting in the fall of 1963 with initial funding to develop a relativity gyroscope experiment. Subsequent decades of development led to groundbreaking technologies to control environmental disturbances on spacecraft, such as aerodynamic drag, magnetic fields and thermal variations. The mission's star tracker and gyroscopes were the most precise ever designed and produced.GP-B completed its data collection operations and was decommissioned in December 2010."The mission results will have a long-term impact on the work of theoretical physicists," said Bill Danchi, senior astrophysicist and program scientist at NASA Headquarters in Washington. "Every future challenge to Einstein's theories of general relativity will have to seek more precise measurements than the remarkable work GP-B accomplished."

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.

BEIJING, Feb. 13 (Xinhua) -- Chinese Premier Wen Jiabao has invited a group of ordinary people from all walks of life to seek their opinions on drafts of a government work report and the country's economic and social development blueprint for the next five years.The representatives, including a farmer, a migrant worker, a rural doctor and a community worker, were invited to Zhongnanhai, the central leadership compound in downtown Beijing, on Jan. 25. Some details of the meeting were made public on Sunday.At the meeting, Wen said, "Ordinary people are in the best place to evaluate government's work, and listening to public opinion will allow us to know how government policies are carried out at grass-roots level, and what difficulties people are facing."Liu Hongwei, a farmer from northeastern Heilongjiang Province, suggested that government increases investment in agricultural water conservancy projects in case of natural disasters such as severe drought this winter in north China.Wen said this year the government would invest more in water conservancy while starting retrofitting the grid in rural areas to guarantee electricity supply for both residential consumption and irrigation of crops.Wen also assured Liu that the government would raise purchasing price of grains so as to protect the interests of grain farmers.Xie Yuanli, an electric welder from northeastern Jilin Province, expressed his wish that governments give greater support and care to industrial workers.Dong Zhiping, a migrant worker working on construction site in central Hunan Province, complained that some enterprise owners refuse to pay migrant workers insurance against work-related injuries, and many migrant workers are not aware of their rights."Once a worker gets injured, his family would suffer grave financial difficulties without the insurance cover," Dong said.Wen said the government was working on the issue, such as promoting better implementation of government regulations on workplace injury-related insurance, which became effective in 2003.The meeting also touched upon issues of favorable policies to small and medium-sized enterprises, fair treatment of village doctors, stronger support to facilities for senior citizens, boosting space science and technology and improving vocational training, among others.The drafts of the 12th five-year program, or the national development plan for 2011 to 2015, and the government work report will be delivered for review early next month at a plenary session of the National People's Congress (NPC), China's national legislature.
