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."

BEIJING, Jan. 22 (Xinhua) -- On the eve of Spring Festival, people across China marked the last moments of the Year of the Rabbit with cheerful celebrations, while exchanging their wishes for a better and prosperous Year of the Dragon.Spring Festival, or Chinese New Year, falls on Monday but the week-long holiday started Sunday, with families, urban and rural as well as rich and poor, dining together and watching the year out in cheer.In a new community in Zhengzhou, capital of central China's Henan province, villagers relocated there for the nation's South-North Water Diversion project have their festival feasts paid for by the government."I've been buzzing around from office to office to get the festival allowances. Today is the third time money has been doled out before Spring Festival," said Lu Songtao, director of the resident committee of Jinyuan.The 60 households in Jinyuan are among the 330,000 people China has resettled for the central route of the massive water project, which aims to transport water from the Yangtze River to the country's drought-prone northern regions, including Beijing.Two month after bedding down in new homes with the help of government subsidies, villagers now wish their careers can also take off in the Year of the Dragon."There are many factories nearby, and I will start looking for a job right after the New Year, either in a battery plant or a food processing factory," said villager Liu Guizhi.In Wuhan, capital of Hubei province, sanitation workers who chose to stay on duty rather than be with their families during the festival ended up dining with the mayor."I'd like to thank you for a year's hard work that has kept the city beautiful," said Tang Liangzhi, mayor of Wuhan, at a banquet held on Saturday for 100 representatives of street cleaners.Though Spring Festival is an important family occasion for most Chinese, many cleaners could not leave their jobs as the week-long fireworks frenzy usually litters city streets with tonnes of cardboard and scraps of paper."I had been so busy today that I came to the banquet right from the street, with the my uniform on," said 51-year-old Yang Houjian."But I am deeply moved -- I feel my work is honored by the whole society," he said.This year's Spring Festival also brings a festive atmosphere to Xinjiang and Tibet, though celebrating the festival is not a tradition for many ethnic groups there. Young people, in particular, are mesmerized by the festival's "exotic" flavor."My friends from the Han community told me that it's their tradition to wear something red when their animal signs coincide with that of the year. So I bought a red bracelet as I'm a 'Dragon,'" said 23-year-old Hanati Kizihan, who is a Kazakh in Urumqi.Many households and institutions in Tibet have also put up national flags and portraits of Chinese leaders in honor of the national festival. On Sunday, a gigantic picture of China's central leaderships, represented by Mao Zedong, Deng Xiaoping, Jiang Zemin and Hu Jintao, was unveiled at the regional government building in Lhasa to celebrate the festival. 

SEOUL, Nov. 8 (Xinhua) -- Samsung Electronics, the world's largest flat screen TV vendor, said Tuesday that it has suspended its plan to develop active shutter three-dimensional (3D) TVs with RealD, the U.S.-based 3D technology supplier."Samsung has decided to focus on our own initiatives of 3D technology, and continues to research and develop next-generation 3D display technologies, including a glasses-free 3D solution for the home," the tech firm said in an e-mailed statement.The active shutter 3D technology drew public attention after Samsung reached a deal with RealD earlier this year to jointly develop such technology, aiming to unveil 3D TVs based on the technology early next year.The active shutter is a next generation 3D technology that incorporates merits from both shutter-glass (SG) technology, which Samsung adopted, and film patterned retarder (FPR) technology, which LG introduced in December last year.The SG technology has been touted as better picture quality and deeper 3D images, but the eyewear is heavier because it requires batteries and chips to work. The active shutter 3D technology moved its function of 3D image creation from eyewear to flat panel, making the eyewear lighter.Despite the upgraded technology and its convenience, Samsung decided to focus on its existing SG technology as the global TV market is grappling with weak demand. The penetration rate, which gauges the ratio of 3D sets against the total flat screen TVs, was expected to rise to 9.9 percent by year-end from the 3 percent a year earlier, according to Woori Investment & Securities, a local securities firm.

BALI, Indonesia, Nov. 19 (Xinhua) -- Chinese Premier Wen Jiabao said on Saturday that an immediate task for East Asian nations in the face of the global financial crisis was to maintain continuous, rapid development of the region's economy.Addressing the 6th East Asia Summit, Wen said East Asian nations should provide momentum for the world economy's robust, sustainable and balanced development."We should continue to strengthen cooperation and the summit should play a strategic role in this regard," he said.Wen put forward a five-point proposal for boosting the regional economy:First, coping with the international economic and financial crisis should continue to be regarded as a priority, he said.East Asian nations should implement appropriate fiscal and monetary policies in accordance with their national conditions, shore up market confidence, and enhance coordination in the macro-economic policy and financial cooperation.Second, Wen said the region should earnestly carry out and improve agreed free trade arrangements, steadily advance the building of new free trade areas, and further open markets.The Chinese premier called on East Asian nations to counter protectionism and properly handle international trade frictions.Third, the region should encourage expansion of investment and increase investor confidence, he said.It should boost the inner drive for its development through such ways as industrial transfer and regional interconnection, Wen said.Fourth, he called for prioritizing sustainable development as a long-term cooperative goal, stronger cooperation in key fields, help for East Asian countries to transform their economic development model, and intensified cooperation in such areas as energy-saving, environmental protection, education and disaster control, so as to enhance development potential.His final point urged overcoming challenges brought by non-traditional security threats to create a better environment for development, and strengthening cooperation in the fields of information exchange, capacity building and emergency response.Wen said that, as a strategic forum, the EAS facilitated mutual understanding and cooperation between East Asian nations."Under the new situation, we should continue to regard the Association of Southeast Asian Nations (ASEAN) as the dominant power of cooperation at the summit and make efforts to seek and expand interest junctions," he said.China was willing to work with all sides to make the summit more fruitful and benefit more countries and peoples, the Chinese premier said.Echoing Wen's remarks, participants at the summit said under the current international political and economic situation, East Asian cooperation should continue to wield the influence of ASEAN domination and the existing mechanism to intensify mutual support and coordination, and deepen cooperation in the fields of economy and trade, finance, food security, energy security and disaster relief.
