WASHINGTON, Nov. 16 (Xinhua) -- Data from NASA's Galileo spacecraft have provided scientists evidence of what appears to be a body of liquid water, equal in volume to the North American Great Lakes, beneath the icy surface of Jupiter's moon, Europa, the U.S. space agency announced Wednesday.The data suggest there is significant exchange between Europa's icy shell and the ocean beneath. This information could bolster arguments that Europa's global subsurface ocean represents a potential habitat for life elsewhere in our solar system. The findings will be published Thursday in the scientific journal Nature.Europa, which is slightly smaller than Earth's moon, is believed to have a large ocean of salty water deep beneath its frozen crust. Galileo spacecraft, launched by the space shuttle Atlantis in 1989, studied Jupiter, which is the most massive planet in the solar system, and some of its many moons.Pictures of it sent back by Galileo point to a tortured surface of cracks and jumbled ice. Seeking to understand how such weird topography evolved in a place with such dim sunlight, scientists believe that the answer lies in similar processes on Earth.Their model suggests that Europa's ice shell is about 10 kilometers thick and within it are giant pockets of water, lying at depths as shallow as three kilometers. Warm water from these sub-surface lakes wells up in plumes, causing the ice to become brittle, crack and then collapse. The ice turnover would be a plus for the prospects for life, as it would transfer energy and nutrients between the sub-glacial lake and the surface."One opinion in the scientific community has been if the ice shell is thick, that's bad for biology. That might mean the surface isn't communicating with the underlying ocean," said Britney Schmidt, lead author of the paper and postdoctoral fellow at the Institute for Geophysics, University of Texas at Austin. " Now, we see evidence that it's a thick ice shell that can mix vigorously and new evidence for giant shallow lakes. That could make Europa and its ocean more habitable.""The data opens up some compelling possibilities," said Mary Voytek, director of NASA's Astrobiology Program. "However, scientists worldwide will want to take a close look at this analysis and review the data before we can fully appreciate the implication of these results."

SAN FRANCISCO, Nov. 7 (Xinhua) -- Google on Monday added a highly-anticipated service to its Google+ social network, allowing businesses and brands to set up their own pages on the site.Named "Google+ Page," the service is a further challenge to its rival Facebook's fan pages, which has become a major promotion strategy for many business brands over the past several years.Unlike Facebook, Google will not charge businesses and organizations for using the scheme, and will not put ads on the pages. The service is expected to enhance the tech giant's other businesses like search and mobile advertising.Some big brand names, such as Burberry, the Barcelona football club and the Muppets, have already set up their pages.Google noted it will not pass on personal data.In addition to big brands, Google also wants small businesses that have or do not have their own websites to use Google+ Pages as their default presences.According to a report by Ad Age Digital, Google+ Pages will soon be location-aware, allowing local businesses to send offers and deals to mobile phones.According to Google, more than 40 million people have opened an account with its social network, which was launched in June. Although the network is growing very quickly, some analysts said it still has a long way to go to become a major threat to Facebook, which has more than 800 million users.

WASHINGTON, Nov. 29 (Xinhua) -- China and the United States on Tuesday held high-level talks on enhancing cooperation on anti- monopoly and anti-trust enforcement, with an aim to strengthen the bilateral economic and trade relations.This was the first time that the two sides held such meeting since they signed in last July a memorandum of understanding (MOU) on anti-monopoly and anti-trust enforcement cooperation by related enforcement agencies from the two countries.Gao Hucheng, China's International Trade Representative and Vice Minister of the Ministry of Commerce, led the Chinese delegation to the talks with the U.S. delegation headed by Jon Leibowitz, chairman of the U.S. Federal Trade Commission, and Sharis Pozen, acting Assistant Attorney General of the Department of Justice in charge of anti-trust affairs.The two sides briefed each other on the latest developments on the anti-monopoly and anti-trust policies and their enforcement in own country, while discussing ways to further strengthen anti- monopoly and anti-trust enforcement in related industries, during a time of economic downturn.They also reached an agreement on the guidelines of cooperation on pursuing anti-monopoly and anti-trust enforcement in individual cases, such as mergers of corporations, after reviewing the bilateral exchanges and cooperation in this field.It was agreed that the China-U.S. economic and trade relations are the cornerstone of the overall bilateral relationship, and the enforcement of anti-monopoly and anti-trust laws can help secure the smooth development of their economies, to the benefits of both countries and peoples.Such talks are conducive to enhancing mutual understanding of each other's practices in formulating and enforcing anti-monopoly and anti-trust policies, through sharing experiences and increased cooperation, the two sides agreed.In July, three Chinese anti-monopoly law enforcement agencies, the National Development and Reform Commission, Ministry of Commerce and State Administration for Industry and Commerce, signed the MOU on cooperation in anti-monopoly and anti-trust enforcement, with the U.S. Department of Justice and Federal Trade Commission.The document is a long-term framework between China's anti- monopoly enforcement agencies and their U.S. counterparts, designed to promote better enforcement of competition laws and regulations of the two countries. Under the MOU, the two sides will hold high-level consultations, exchange of information on law enforcement and policies, as well as cooperation on specific cases, mainly for mergers.

SAN FRANCISCO, Dec. 2 (Xinhua) -- Only two weeks after its shipment, Amazon's Kindle Fire has already shown the momentum to grab the second place in global tablet computer market, research firm IHS predicted on Friday.Amazon is expected to ship 3.9 million Kindle Fire tablets during the last three months of 2011, the first quarter the product goes on sale, according to preliminary projection from IHS.The number will give Amazon a 13.8-percent share of global tablet market in the fourth quarter, surpassing the 4.8 percent held by No. 3 player Samsung, and second only to Apple's commanding 65.6 percent market share."Nearly two years after Apple Inc. rolled out the iPad, a competitor has finally developed an alternative which looks like it might have enough of Apple's secret sauce to succeed," Rhoda Alexander, senior manager of tablet and monitor research for IHS, said in a statement."Initial market response strongly suggests that Amazon, with the Kindle Fire, has found the right combination of savvy pricing, astute marketing, accessible content and an appropriate business model, positioning the Kindle Fire to appeal to a brand-new set of media tablet buyers," she added.IHS analysts noted that with a price tag of 199 U.S. dollars, the Kindle Fire has set a new bar for pricing, bringing the tablet within reach of a larger portion of the buying public.IHS expects Kindle Fire's rapid ascent to help fuel the expansion of the entire tablet market, now predicting that 64.7 million tablets will be shipped in 2011, higher than its previous forecast of 60 million issued in August.The total tablet shipment number this year will represent a 273- percent growth from 17.4 million units in 2010, said IHS, which has also increased its longer-term projection of global tablet shipment in 2015 to 287.2 million units.

BEIJING, Sept. 30 (Xinhuanet) -- China's space dream took a step closer to reality as the Tiangong-1 module blasted off into the night sky on Thursday from the Gobi Desert.The Long March II-F T1 rocket, under the unmanned module, Tiangong-1, lifted off from the Jiuquan Satellite Launch Center at 9:16 pm as planned.Ten minutes later Tiangong-1 separated from the rocket on its way to orbit, 350 kilometers above Earth. The module deployed its two solar panels, which provide power, at 9:28 pm.At 9:39 pm, Chang Wanquan, chief commander of the manned space program, declared the launch a success as cheers and applause echoed around the command and control center in Beijing.President Hu Jintao and other members of the Standing Committee of the Political Bureau of the Communist Party of China Central Committee went to the center to witness the launch.Premier Wen Jiabao watched at the Jiuquan Satellite Launch Center as the Long March rocket, carrying the space lab, blazed into the night sky.The launch paves the way for China's first rendezvous and docking mission. An unmanned Shenzhou VIII spaceship will be launched in November to dock with Tiangong-1.Two more missions are scheduled for next year and astronauts will board Tiangong-1, which can also function as a space lab.If the mission succeeds, China will become the third country to master spacecraft rendezvous and docking technology following the then Soviet Union and the United States, experts said.Wu Ping, the space program's spokeswoman, said that the ability to rendezvous and dock is vital for building a space station, which China has scheduled for around 2020."A space station cannot be launched in one shot. The modules must be launched separately and then assembled in space," she said.China has invested 35 billion yuan (.47 billion) in total on its manned space program since 1992, when it was approved, she told China Daily.The first phase, from 1992 to 2005, accounted for 20 billion yuan. During this period, China launched six Shenzhou spaceships to set up a system transporting astronauts between Earth and space.In the second phase, from 2005, 15 billion yuan has been spent on projects, including Shenzhou VII and the first rendezvous and docking mission, she explained.Zhou Jianping, chief designer of China's manned space program, said that the space lab and future space station provide a rare platform for conducting experiments that could lead to breakthroughs in the study of materials and biological pharmacy."Experiments made in the microgravity of space can lead to unexpected results," he said.For example, gas and liquid are unable to mix on Earth, but in space they mix naturally, he said."The primary purpose of China's manned space station is to peacefully explore space, and through it, serve mankind," he said.Some have questioned the participation of the military in the program. However, the military has experience in coordinating large-scale requirements that are vital for the program and their involvement reflects international norms, Ministry of National Defense spokesman Geng Yansheng said on Wednesday.He reiterated that China is firmly opposed to the weaponization of space and the program is peaceful.China is now in the second phase of its manned space program. The goal of the program, which has three steps, is to build a 60-ton space station around 2020.The second phase focuses on mastering four key technologies for assembling a space station.The first of these, extravehicular activity, was completed successfully in 2008 after Shenzhou VII was launched.Rendezvous and docking is what is being experimented with. The third technology involves cargo spaceships ferrying supplies to a space lab. The fourth tackles problems concerning the prolonged sustaining of life on a space lab, especially recycling air and water.Besides the manned space program, China launched two lunar orbiters in 2007 and 2010. It plans an unmanned lunar landing around 2013, and returning moon samples in 2017.
