NANJING, Dec. 8 (Xinhua) -- Chinese stargazers will have their best view of a total lunar eclipse in 10 years on Saturday if weather permits, the Zijinshan Astronomical Observatory under the Chinese Academy of Sciences (CAS) said Thursday.Wang Sichao, a research fellow with the observatory, said during the total eclipse, the full moon will not completely disappear from the Earth's shadow, but will take on a brilliant bronze color.He said the eclipse will be the best one seen in China since the last one occurred on Jan. 10, 2001."Theoretically, viewers can observe the eclipse from nearly everywhere in the country on Saturday," said the astronomer.He said the eclipse, the second this year, will last for 51 minutes. It will start at 8:45 p.m. and reach its climax at 10:06 p.m.Wang said Chinese viewers will have to wait until Oct. 8, 2014 to see the next total lunar eclipse.

BEIJING, Dec. 28 (Xinhuanet) -- China started to run its own satellite positioning system, Beidou, on Tuesday as the country climbed the global tech ladder and challenged the monopoly of the West. Beidou, or Big Dipper, the domestic version of the US Global Positioning System (GPS), started providing navigation, positioning and timing data on a pilot basis to China and the neighboring area for free on Tuesday, Ran Chengqi, director of the China Satellite Navigation Office, said. The system, with 10 orbiting satellites, covers an area from Australia in the south to Russia in the north. Signals can reach the Xinjiang Uygur autonomous region in the west and the Pacific Ocean in the east, Ran said. With six more satellites to be launched next year, the system will cover a wider area and eventually the entire globe by 2020 with a constellation of 35 satellites, he said. The accuracy of the positioning service will also improve as more satellites orbit. During the trial run Beidou can offer positioning to within 25 meters but when the system is officially launched next year accuracy will be enhanced to within 10 meters, he said. With the system operational China is the third member of an elite group, along with the US and Russia, to develop a satellite navigation system. The US spent 20 years and more than billion on the GPS. Completed in 1994, the system has 24 navigation satellites and is widely used around the world. Beidou has its own unique features, Ran said. "It not only tells users where they are and what time it is but also allows users to tell others the information through short messages," Ran said, adding that this feature is being considered by other systems. Russia's Glonass system achieved a 24-satellite constellation in 1996 but succumbed to funding problems. The rebuilding of the Glonass system is almost finished and Russian media reported that the system resumed service earlier this month. The European Union and the European Space Agency are building the Galileo satellite navigation system. Japan and India also intend to build independent regional navigation systems. "Countries build their own systems because owning an independent satellite navigation system is important to economic development and national security," said Pang Zhihao, deputy editor-in-chief of the monthly publication Space International. There have long been concerns that the US might take its dominant GPS offline in certain international emergencies. Ran said that the Beidou system will be "helpful" to national defense. An "independent and controllable" satellite navigation system can guarantee national economic development as well as scientific and industrial strength, he said. China started to reduce its reliance on the GPS in 2000, when it sent an experimental pair of positioning satellites into orbit. But Ran stressed that Beidou is "built for the world", as the compatibility of various systems enhances reliability for users. "If you only use GPS there will be blind spots. But from demonstrations I saw recently, receivers that are compatible with Beidou will overcome these problems," he said. He encouraged enterprises at home and abroad to join the research and development of application terminals compatible with Beidou. The office put a test version of the system's Interface Control Document online on Tuesday, which is a technical document vital for the manufacturing and development of receivers and chips. The prospects for the country's satellite navigation industry look bright, experts said. Analysts estimated that around 2020 the industry's output will reach 0 billion globally, including 400 billion yuan ( billion) to 500 billion yuan from China. According to the 2011 Report on Application of Geosaptial Information in China released on Monday, the number of satellite navigation application terminals in China has grown from less than 100,000 in 2000 to more than 10 million in 2009. The number is expected to reach 340 million by 2015. An insider said a compatible receiver for car use costs 1,600 yuan to 3,000 yuan, higher than a GPS receiver. "Chips supporting both GPS and Beidou systems have been developed, and terminals have been produced. There are no technical hurdles for the industry," said Han Shaowei, CEO of Beijing-based Unicore Communications Inc, a major navigation chip and core component provider. Beidou application terminals have been put into use in vehicles, such as government cars in Guangdong province. Ran said that private terminal makers in Guangdong are testing their receivers on the road, and the products seem stable. "The price of the compatible terminals is expected to be slashed next year," he said.

BEIJING, Dec. 26 (Xinhua) -- China has launched a one-year inter-agency national campaign aiming to return most street children home, the Ministry of Civil Affairs (MCA) said Monday.The MCA will lead the campaign, which is joined by the ministries of education, public security, financial, health, human resources and social security, and housing and urban-rural development, an MCA statement said."We will try our best to identify most street children in cities and send them home by the end of 2012," the statement said.Minister Li Liguo of Civil Affairs said, ministries concerned should strengthen communication and coordination, and speed up the revision of regulations on the relief of city beggars and vagrants.The MCA also urged provincial governments to set up special offices coordinating the campaign. Several provinces, such as Hebei and Yunnan, have been working on this, the statement said.Police will step up their efforts to identify and rescue street children who wander near railway stations, major tourist sites, business areas and subway stops, while civil affairs departments will assist investigation and provide shelter for homeless children, the statement said.Urban communities and neighborhoods are asked by the ministry to report homeless children to local police. Police and civil affairs departments will cooperate to ascertain the whereabouts of their parents or guardians.In home places of street children, education departments are urged to send them to schools or vocational schools, and those from needy families will have their tuition reduced or waived.Health departments are required to offer street children easy access to medical facilities in emergency cases. Hospitals listed in the campaign will treat sick street children free of charge.

BEIJING, Oct. 12(Xinhuanet) -- People allergic to peanuts may find relief in a new research by American scientists, according to Huffington Post Monday.Scientists from the Northwestern University Feinberg School of Medicine have found a way to turn off allergic responses by creating an immune system tolerant to peanuts.They attached peanut proteins, the source of the allergy, to white blood cells of mice. Then the mice's immune systems would recognise the proteins and become tolerant to them.When people eat peanuts, allergic human bodies would recognize peanut proteins as invading pathogens and trigger immune responses like throat swelling, even closing up, which can be lethal. Ditto for mice's bodies.But when peanut protein attached to the body's own cells, the immune systems would regard the peanut proteins as perfectly normal and not attack the cells, said Paul Bryce, an assistant professor involved in the study. Then the allergic responses disappeared.The research was conducted on mice. But the scientists expected the method to cure peanut allergies could apply to humans, according to Huffington Post.Although the research was promising, it did not mean that peanut allergies in humans could be actually cured in the foreseeable future, said Dr. Clifford Basset medical director at Allergy and Asthma Care of New York, to ABC News, "Its all about education, prevention and preparedness".
