BEIJING, Oct. 21 (Xinhuanet) -- A team of European researchers announced that they have found vast water vapor out of our solar system, according to a study in the U.S. journal Science Friday.Using Herschel Space Observatory, a European Space Agency satellite, the researchers observed that the vast water vapor enveloped a 175-light-year-away star and its surrounding dusk disk, which will eventually form a planet.The water vapor, which is "enough to fill thousand of Earth ocean", may rain down and seed the future oceans on the young planet, as it did on the Earth 4.5 billion years ago, the researchers suggested."Scientists have long suspected there were these reservoir of cold water hiding in the outer regions of planet disk, ... now the theory gets considerably stronger." said astronomer Michiel Hogerheijde of Leiden Observatory in the Netherlands.The finding not only explained where our Earth's ocean came from, but also indicated that there are likely to be many "ocean worlds" throughout the galaxies, he concluded.

BEIJING, Sept. 30 (Xinhuanet) -- Miners, construction workers and people in hotel and food service industry are most likely to smoke in the U.S., according to new research finding.The finding was contained in a report released Thursday by the U.S. Centers for Disease Control and Prevention (CDC).According to the finding, miners and people in hotel and food service have a cigarette smoking rate of 30 percent, followed closely by construction workers' 29.7 percent.Both rates are much higher than the average smoking rate of 19.6 percent among all U.S. working adults.Workers in the education services industry have the lowest smoking rate, with 9.7 percent, followed by the 10.9 percent of workers in company management, the report said.Low education levels are a factor in high smoking rates, along with poverty and gender, said Ann Malarcher, senior scientific adviser at the CDC."Although some progress has been made in reducing smoking prevalence among working adults," the report wrote, "additional effective employer interventions need to be implemented."Smoking kills an estimated 443,000 each year in the U.S., costing about 193 billion U.S. dollars annually in direct health care expenses and productivity loss.

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.

HONOLULU, United States, Nov. 12 (Xinhua) -- Chinese President Hu Jintao met his U.S. counterpart Barack Obama in Honolulu, Hawaii, Saturday to discuss Sino-U.S. ties and major world and regional issues.Hu and Obama were meeting before the Economic Leaders Meeting of the Asia-Pacific Economic Cooperation (APEC) scheduled for Saturday and Sunday in Hawaii.In a meeting with U.S. Secretary of State Hillary Clinton on Thursday in Honolulu, Chinese Foreign Minister Yang Jiechi said the Hu-Obama meeting has great significance for the steady development of China-U.S. relations.He noted that under the current situation, China is ready to make concerted efforts with the United States to deepen understanding, enhance mutual trust and better carry out the consensus reached by the two countries' leaders, so as to build a cooperative partnership based on mutual respect and mutual benefit.Clinton said President Obama looked forward to his meeting with President Hu.The U.S. side values its cooperative partnership with China, which is not only in the interests of both sides, but also holds great importance to the world at large, she said.Earlier this month, Hu and Obama met in Cannes, France, on the sidelines of a summit of the Group of Twenty (G20) and exchanged views on bilateral ties and the G20 summit.
