HAIKOU, Jan. 28 (Xinhua) -- China's aviation authorities on Friday started to allow helicopters to fly in low-altitude airspace over the tourist island of Hainan on a trial basis for the first time. The aim is to eventually open a part of the country's tightly-controlled airspace to private aircraft.Four helicopters were manned by eight pilots from Shanghai-based Zhengyang Investment Group, a leading domestic firm in the general aviation industry. They are expected to conduct test flights in the sky, 1,000 meters above the ground in Hainan in the next two months.The flight test will collect data for low-altitude flying and test the ground control system's response to emergencies, said Zou Jianming, chairman of Zhengyang Investment Group.Hainan is the first place in China to conduct test flights of private aircraft in low-altitude airspace, said Jiang Sixian, deputy governor of the province. Domestic and foreign firms are both welcome to invest in Hainan's general aviation sector to develop world-class tourism here.China's low-altitude airspace is controlled by the Air Force and the Civil Aviation Administration of China (CAAC). Every private aircraft flight needs approval, and the procedure can take from one day up to a week.But last November, the State Council and the Central Military Commission said that part of the low-altitude airspace would be opened to promote the country's general aviation sector, including the purchase and use of private planes.General aviation refers to the part of the aviation industry that excludes flights for military, law enforcement and public transport. China has only 900 aircraft, 80 airports and fewer than 10,000 pilots in the general aviation segment.The market for general aviation in China is valued at only 13 billion yuan (1.98 billion U.S. dollars) but is expected to grow by 15 percent annually until 2020, Hainan aviation officials said.

BEIJING，March 11 (Xinhuanet) --A poor diet during pregnancy may result in health problems such as diabetes for the offspring in later life, according media reports Friday quotting a new research.Based on a study of rats, researchers from the University of Cambridge altered the protein content of the mother's diet during pregnancy as they found that rats were more vulnerable to the effects of diseases if their mothers were malnourished while they were pregnant.Further, the study also showed that an imbalanced diet in the expectant mother can compromise the long-term functioning of a gene in the child. And the gene, named Hnf4a, is believed to play a major role in the development of the pancreas and in the production of insulin.The researchers held similar mechanisms seen in the rat study could occur in humans, and that the effects might be felt by more than just the immediate offspring."What is most exciting about these findings is that we are now starting to really understand how nutrition during the first nine months of life spent in the womb shape our long term health by influencing how the cells in our body age," said Susan Ozanne, senior author of the paper and senior fellow from the Institute of Metabolic Science at the University of Cambridge.And Jeremy Pearson, associate medical director at the British Heart Foundation, said: "The reasons why are not well understood, but this study in rats adds to the evidence that a mother's diet may sometimes alter the control of certain genes in her unborn child.""It's no reason for expectant mothers to be unduly worried. This research doesn't change our advice that pregnant women should try to eat a healthy, balanced diet," he added.

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."

MOHE, Heilongjiang, Feb. 3 (Xinhua) -- Some 1.318 million tonnes of crude oil had flowed through an oil pipeline from Russia's far-east to China by Jan. 31, a month after the pipeline began operating, an officer of the Chinese operator of the pipeline said.The pipeline, which originates in the Russian town of Skovorodino in the far-eastern Amur region, enters China at Mohe and terminates at Daqing City of northeast China's Heilongjiang Province.The facility withstood the test of the severe coldness since it was put into operation on Jan. 1 and no production accident has been reported so far, said Gou Hanghai, director of the Mohe administration station of the pipeline.The pipeline remains a daily oil delivering capacity of 42,000 tonnes, he saidThe 1,000-km-long pipeline will transport 15 million tonnes of crude oil from Russia to China per year from 2011 to 2030, according to an agreement signed between the two countries.Some 72 kilometers of the pipeline is in Russia and 927 kilometers of it is in China.

BEIJING, Feb.9 (Xinhua) -- China's State Council, the nation's cabinet, pledged Wednesday to step up efforts to boost grain production as relentless droughts continue to wreak havoc in north China's wheat growing regions.To encourage farmers to plant more and increase production, China will increase minimum purchase prices for grain produced in 2011 by up to 21.9 percent from that in 2010, according to a statement released after a State Council executive meeting presided over by Premier Wen Jiabao.The purchasing prices for japonica rice will rise 21.9 percent to 128 yuan (19.4 U.S. dollars) per 50 kilograms this year, while prices for early and middle-late indica rice will increase 9.7 percent and 10.3 percent to 102 yuan and 107 yuan per 50 kilograms respectively.Further, the central government will allocate 1.2 billion yuan to subsidize the purchase of anti-drought technologies for winter wheat-growing regions.According to the statement, the government has already allocated 4 billion yuan for rural water conservation projects and another 2 billion yuan will be allocated for farm irrigation systems and safe drinking water projects.The government had also pledged to fund 2,000 professional groups in insect-prevention in the worst-hit counties, the statement said.China's main wheat-growing regions, including Shandong, Henan, Hebei, Anhui, Shanxi, Shaanxi, Gansu and Jiangsu provinces, have been plagued by ongoing droughts since last year.
