BEIJING, Feb. 11 (Xinhua) -- Chinese society will age fast in the next five years and the government must be well prepared for the demographic change, said Chinese Vice Premier Hui Liangyu here Friday.Government policies needed adjusting and the social insurance network should be improved, Hui said at a meeting of the China National Committee on Aging.Also services for senior citizens should be better developed to meet their needs, said Hui, also the committee's director.The country will also work to expand the pension system in the rural area and cover as many senior people as possible, he said.Health authorities plan to build more medical facilities for the elderly and urban planning should take the needs of senior people into consideration, he said.

BEIJING, Jan. 24 (Xinhua) -- China has invested 115 billion yuan (17.45 billion U.S. dollars) on the South-to-North Water Diversion Project as of the end of last year, a senior official said Monday.E Jingping, director of the Office of the South-to-North Water Diversion Project Commission (SNWDPC) of the State Council, said construction on 40 projects began last year, marking a new annual record.No major accidents happened while constructing the projects last year, E said.The South-to-North Water Diversion Project is designed to divert water from the water-rich south of China, mainly the Yangtze, the country's longest river, to the country's arid northern regions. It will consist of three routes: an eastern, middle and western route. The project started with construction of the eastern route in 2002.Up until now, both of the eastern and middle routes were already under construction. The western route, meant to replenish the Yellow River with water from the upper reaches of the Yangtze through tunnels in the high mountains of western China, is still in the planning stage.About 330,000 people in Hubei and Henan Provinces will be relocated before the middle route is completed in 2014.

BEIJING, Jan. 26 (Xinhua) -- China's top leaders Wednesday evening attended a gala held at the Great Hall of the People to celebrate the coming Chinese lunar new year, which falls on Feb. 3, with armymen and the common people.Chinese President Hu Jintao and other members of the Standing Committee of the Political Bureau of the Communist Party of China (CPC) Central Committee Wu Bangguo, Wen Jiabao, Jia Qinglin, Li Changchun, Xi Jinping, Li Keqiang, He Guoqiang and Zhou Yongkang, watched the artistic performance and extended their festival greetings to the audience.Chinese top leaders Hu Jintao, Wu Bangguo, Wen Jiabao, Jia Qinglin, Li Changchun, Xi Jinping, Li Keqiang, He Guoqiang and Zhou Yongkang pose with performers for a group photo after an evening party welcoming the upcoming Chinese traditional Spring Festival in Beijing, capital of China, Jan. 26, 2011. Military and civilian artists presented various programs at the gala ranging from Peking Opera, chorus to acrobatic shows, which were welcomed and hailed by the audience.

WASHINGTON, May 11 (Xinhua) -- NASA's Dawn spacecraft has obtained its first image of the giant asteroid Vesta, which will help fine-tune navigation during its approach, the U.S. space agency announced Wednesday.Dawn expects to achieve orbit around Vesta on July 16, when the asteroid is about 117 million miles from Earth.The image from Dawn's framing cameras was taken on May 3 when the spacecraft began its approach and was approximately 752,000 miles (1.21 million km) from Vesta. The asteroid appears as a small, bright pearl against a background of stars. Vesta also is known as a protoplanet, because it is a large body that almost formed into a planet."After plying the seas of space for more than a billion miles, the Dawn team finally spotted its target," said Carol Raymond, Dawn's deputy principal investigator at NASA's Jet Propulsion Laboratory in Pasadena, California. "This first image hints of detailed portraits to come from Dawn's upcoming visit."Vesta is 330 miles (530 km) in diameter and the second most massive object in the asteroid belt. Ground- and space-based telescopes obtained images of the bright orb for about two centuries, but with little surface detail.Mission managers expect Vesta's gravity to capture Dawn in orbit on July 16. To enter orbit, Dawn must match the asteroid's path around the sun, which requires very precise knowledge of the body's location and speed. By analyzing where Vesta appears relative to stars in framing camera images, navigators will pin down its location and enable engineers to refine the spacecraft's trajectory.Dawn will start collecting science data in early August at an altitude of approximately 1,700 miles (2,700 km) above the asteroid's surface. As the spacecraft gets closer, it will snap multi-angle images allowing scientists to produce topographic maps. Dawn will later orbit at approximately 120 miles (200 km) to perform other measurements and obtain closer shots of parts of the surface. Dawn will remain in orbit around Vesta for one year. After another long cruise phase, Dawn will arrive in 2015 at its second destination, Ceres, an even more massive body in the asteroid belt.Gathering information about these two icons of the asteroid belt will help scientists unlock the secrets of our solar system's early history. The mission will compare and contrast the two giant asteroids shaped by different forces. Dawn's science instruments will measure surface composition, topography and texture. Dawn also will measure the tug of gravity from Vesta and Ceres to learn more about their internal structures. The spacecraft's full odyssey will take it on a 3-billion-mile (5-billion-km) journey, which began with its launch in September 2007.

SAN FRANCISCO, May 4 (Xinhua) -- Intel Corp. on Wednesday announced that it will mass-manufacture chips using new transistors featuring a three-dimensional (3-D) structure, calling it a technical breakthrough in microprocessors.The 3-D transistor, called Tri-Gate, represents a fundamental departure from the two-dimensional planar transistor structure that has powered computers, mobile phones and other modern electronics, Intel said."Intel's scientists and engineers have once again reinvented the transistor, this time utilizing the third dimension," Paul Otellini, Intel's chief executive officer, said in a statement.Intel on Wednesday also demonstrated a 22-nanometer (nm) microprocessor, codenamed "Ivy Bridge," which will be the first high-volume chips to use the new 3-D transistors.Ivy Bridge is scheduled for high-volume production readiness by the end of this year, the company said.According to Intel, the 3-D transistors enable chips to operate at lower voltage with lower leakage compared to previous transistors, providing up to 37 percent performance increase at low voltage versus the company's 32nm planar transistors.The gain means that the new 3-D transistors are ideal for use in small handheld devices, which operate using less energy to " switch" back and forth, Intel noted.
