BEIJING, Feb. 8 (Xinhua) -- China would continue expanding its radio and television networks coverage in the country's rural areas in the 2011-2015 period, according to the State Administration of Radio, Film and Television (SARFT).In the five-year period, efforts would focus on ensuring access to radio and TV services in those villages with less than 20 households, the SARFT said in a statement.It noted that China's other villages which had more than 20 households were already covered by the radio and TV networks, thanks to government's continuous efforts in this regard.China's central and local governments poured over 15.7 billion yuan (2.38 billion U.S. dollars) into the upgrading of the radio and TV networks in the country's rural areas in 2006-2010.Official figures indicated that 96.31 percent and 97.23 percent of China's population had access to radio and TV services respectively in 2009. The ratio was 86.02 percent and 87.68 percent respectively in 1997.

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."

WELLINGTON, May 13 (Xinhua) -- While it's long been known that a little sunshine can spread happiness, researchers in New Zealand have found that it can also save the lives of pneumonia patients.Medical scientists have found that vitamin D, which is absorbed through the skin and produced with exposure to sunlight, is a major factor in the survival rate of pneumonia patients.Researchers at Waikato University collaborated with doctors at Waikato Hospital, both Hamilton-based institutions, to study blood samples of 112 patients admitted to the hospital with pneumonia during the winter.They found that those with severe vitamin D deficiency 17 of the patients were more likely to die within a month, compared with patients with normal or slightly low vitamin D levels.Dr Bob Hancox, of the hospital's department of respiratory medicine, said five of the 17 died, a 29-percent mortality rate, compared with four deaths among the 95 patients with higher vitamin D levels, a 4-percent mortality rate."The analysis confirmed that the difference in mortality rates between the two groups was very unlikely to be due to chance," Hancox told Xinhua.Vitamin D deficiency was a concern around the world, Hancox said."Sunlight is the main source of vitamin D, so it tends to be a winter problem in temperate climates when people spend a lot of time indoors. But it occurs in all countries and vitamin D deficiency is believed to be a major problem worldwide."There is accumulating evidence that we need vitamin D to help fight infections, such as pneumonia as we have shown, as well as improve bone health," he told Xinhua."What is not yet clear is whether we can do anything about it. We don't know whether treating people with vitamin D supplements would help to prevent or treat respiratory infections. This is what we need to find out now."Dr Ray Cursons, of the Biological Sciences department at Waikato University, said patient age, sex, additional health conditions, and other prognostic factors did not affect the research outcome, although researchers still could not establish a causal link between vitamin D deficiency and mortality in the patients.Waikato Hospital D respiratory specialist Dr Noel Karalus said it was not yet known whether giving patients vitamin D supplements after their admission to hospital with respiratory tract infections would alter outcomes."It may transpire that vitamin D helps us avoid infection rather than cure it once established."Cursons said the best source of vitamin D was sunlight as dietary sources such as fatty fish and cod liver oil did not contain enough vitamin D."There is still some controversy regarding the optimal daily allowance of vitamin D. How much we absorb through the skin depends on sun exposure, skin type and geographical latitude. M ori and Pacific Islanders absorb less because of their darker skin, and people in colder climates also have lower levels of vitamin D. "Pneumonia is the single largest cause of death in children worldwide, killing an estimated 1.6 million children under the age of five each year, according to the World Health Organization.The research findings are published in the journal Respirology, published by the Asian Pacific Society of Respirology, this month.

BEIJING, Feb. 17 (Xinhua) -- China's new rules for reviewing proposed mergers and acquisition (M&A) deals by foreign firms on grounds of national security would benefit both Chinese and foreign investors, a Ministry of Commerce (MOC) spokesman said Thursday.The rules will facilitate the growth of foreign-invested enterprises (FIEs) in China and improve the quality and structure of foreign direct investment (FDI) flowing into China, MOC spokesman Yao Jian said at a press conference.The move also marked an improving legal environment for the security of China's business sector along with its opening-up drive, given that M&A by FIEs will increasingly become a trend in the coming years, Yao said."The adoption of the rules in China will also increase policy transparency and improve law-based government administration," said Yao.Yao's words came after the State Council, China's Cabinet, announced last Saturday that it was establishing a panel to check whether M&A deals struck by foreign firms in the country endanger national security.The panel will review attempts by FIEs to buy or merge with domestic companies whose business pertains to national defence, agriculture, energy, resources, key infrastructure, transport systems, key technology sectors and important equipment manufacturing industries, according to a statement published on the central government's website www.gov.cn.The review will be conducted by a foreign investment security review board under the cabinet, members of which come from the National Development and Reform Commission (NDRC), the MOC and other agencies.The new regulations, which take effect in March, come at a time when China is expected to see more M&A deals struck by foreign firms.Currently, inward M&A accounts for about 3 percent of China's total FDI, a sharp contrast with the global average level of more than 70 percent, said Yao. "M&A by FIEs will become a major trend in China."China's taking in FDI through more M&A will promote industrial consolidation and restructuring, and it will also mean more efficient utilization of the existing resources, he said."As the share of M&A in the FDI will probably rise from the current 3 percent to 8 percent, 10 percent or even more, it is necessary to timely formulate China's own rules governing foreign takeovers in line with international standards," Yao said.In April 2010, the State Council said in a statement that foreign investment should be allowed to be more diversified and foreign investors encouraged to participate in the consolidation and restructuring of domestic firms via equity holdings or acquisitions.He Manqing, a researcher with the Chinese Academy of International Trade and Economic Cooperation of the MOC, said "It is right and proper to impose regulations and requirements on proposed M&A deals in the sectors of strategic importance and those involving national security.""The introduction of the regulations conforms to the new trend in China's receiving of FDI and indicates that China's regulations on FDI are becoming more mature," said He.The NDRC said Wednesday that national security scrutiny would only occur when foreign companies take a majority stake in a domestic M&A deal, meaning that a minority stake purchase will not trigger a review."The new rules draw references from similar rules in the United States, Germany and Canada," the NDRC said in a statement on its website.The NDRC also said that the new regulations were in line with World Trade Organization rules and did not imply that China had changed its policies on opening up and attracting FDI.China's FDI jumped 23.4 percent in January to 10.03 billion U.S. dollars, said Yao. The monthly growth rate was up from December's 15.6 percent.As the world's top investment destination, China received a total of 105.74 billion U.S dollars in FDI in 2010, up 17.4 percent year on year, the MOC said last month.

BEIJING, Apirl 1 (Xinhuanet) -- An Ariane rocket launch of two communications satellites was aborted Wednesday after a technical hitch at the scheduled moment of liftoff in French Guiana on Wednesday.According to Arianespace, the Ariane 5 rocket's Vulcain main engine ignited as scheduled at 5:45 pm EDT (21:45 GMT), but the checkout process during ignition detected an unspecified anomaly, shutting down the engine before the two solid-rocket boosters ignited.The 165-foot (50-meter) tall Ariane 5 rocket's main engine's checkout process "was not completed successfully, preventing the boosters' ignition and thereby aborting the mission," Arianespace officials said. "The Ariane 5 and its two payloads remain in a safe mode on the launch pad."The Ariane 5 rocket uses a Vulcain 2 first stage engine assisted by two solid rocket boosters to launch satellite payloads into orbit. The Vulcain 2 engine is fueled by cryogenic liquid hydrogen and liquid oxygen and is designed to burn for about 600 seconds to boost payloads into space.Jean-Yves Le Gall, Arianespace president, said it would return the rocket to the final assembly building to prepare it for another launch attempt while investigating the cause of the problem. No new launch date was immediately announced.The Ariane 5 was to launch the Yahsat Y1A and Intelsat New Dawn communications satellites.
