BEIJING, Feb. 28 (Xinhua) -- Construction began on China's first low-speed maglev line Monday in Beijing, a project that will make China only the second country with a low-speed maglev line after Japan.The project marked China's ability to industrialize low-speed maglev technologies, said Chang Wensen, father of China's maglev technology and professor at the National University of Defense Technology.The 10-kilometer line runs from Shimenying Station in west Beijing's Mentougou District to Pingguoyuan Station in the Shijingshan District.The line, a section of Line S1 on the Beijing subway network, is expected to be completed in 2013 with a designed speed of 100 to 120 km per hour.China's research of maglev technologies was started in the 1980s by a team led by Chang Wensen. A 204-meter test line in central China's Hunan Province and a 1.5-km test line in north China's Hebei Province were built jointly by Beijing Maglev Technology Development Co., Ltd. and National University of Defense Technology.The intensity of the magnetic field had been tested as safe, according to a test report of Institute of Electrical Engineering, Chinese Academy of Sciences.The cost of the low-speed maglev line was estimated at 300 million yuan (4.6 million U.S. dollars) per kilometer, slightly more than light rail, but cheaper than the subway, which cost more than 600 million yuan a kilometer, said Li Jie, director of technology research center of National University of Defense Technology.The technology was also under consideration for Line 8 of the subway network in Shenzhen, in south China's Guangdong Province, said Liu Zhiming, board chairman of Beijing Maglev Technology Development Co., Ltd.."If Shenzhen adopts the technology, Line 8 will be China's second low-speed maglev line," he said.The world's first low-speed maglev line, at 8.9 km long, was completed in Japan in March 2005.Maglev, short for magnetic levitation, technology uses a large number of magnets to lift and propel a vehicle, making it faster, quieter and smoother than conventional wheeled transport systems.High-speed maglev vehicles can reach speeds of 450 km per hour and are usually used in long distance transportation, while low-speed maglev lines are usually used in short distance transportation.Construction also began on another seven lines on the Beijing subway network Monday.With an investment of 82 billion yuan (12 billion U.S. dollars), the eight lines will total 113.7 km in length and are expected to open from 2013 to 2015.Beijing has 16 lines under construction.

MOSCOW, Feb. 9 (Xinhua) -- China's steady economic rise causes both high hopes and anxiety among world leaders, but a Russian expert believes China's peaceful development is an opportunity for the entire world.Yakov Berger of the Far East Institute of the Russian Academy of Sciences told Xinhua that China's policy of peaceful development is a strategic choice, aimed at long-term and sustainable growth."China overcame the global financial crisis, decreased poverty, and increased people's wealth," Berger said."Still, many important tasks for China remain to be fulfilled and first of all, modernization, industrialization and urbanization. This is why China needs strong and long-lasting peace," he said.Berger said China's policy of peaceful development has already won support from the majority of countries, so they are willing to cooperate with the world's most powerful developing nation."China's peaceful development gives chance to all people in the world, as China became the main engine of the global economic development. Many developed countries are gravitated to China because they depend on Chinese supplies and the Chinese market," Berger said.However, although some countries are aware that China's sustainable growth requires peace and stability, some eye China's growing influence as negative, the professor said.Berger said that Beijing tries to persuade Washington that China's rise does not threaten American security. The question, then, is to what degree is the U.S. ready to accept the new reality, Berger said.Berger cited two main reasons why some Western politicians don't trust Beijing."First, this is a natural response from the people who got used to a certain world order," he said, "Such an order implies the existence of the so-called 'golden billion' people who have access to all of civilization's benefits while the other five billion can't make ends meet."Berger said that when China attempts to achieve the same living standards, that induces some fears based on the notion that the Earth resources are limited.Berger believed the second reason is xenophobia and racism, which generates talk about the "Chinese threat.""But they talked about the 'China threat' even in times when China used to be an underdeveloped nation," Berger noted.

LOS ANGELES, March 18 (Xinhua) -- The moon will move closer to Earth than it has been in more than 18 years Saturday night, space. com reported on Friday.On Saturday afternoon at 3 p.m. Eastern Daylight Time (1900 MGT) , the "supermoon", as dubbed by some observers, will arrive at its closest point to the Earth in 2011: a distance of 221,565 miles ( 356,575 kilometers) away, and only 50 minutes earlier, the moon will officially be full, the report said.At its peak, the supermoon may appear 14 percent larger and 30 percent brighter than lesser full moons (when the moon is at its farthest from Earth), weather permitting, said the report.Yet to the casual observer, it may be hard to tell the difference, according to the report.Scientists say it is a fluke of orbital mechanics that brings the moon closer to Earth.The supermoon will not cause natural disasters, such as the Japan earthquake, NASA scientists say.In December 2008, there was a near-supermoon when the moon turned full four hours away from its perigee - the point in its orbit that is closest to Earth. But this month, the full moon and perigee are just under one hour apart, promising spectacular views, depending on local conditions, the report said.

LOS ANGELES, April 8 (Xinhua) -- NASA's Wide-field Infrared Survey Explorer (WISE) has discovered a rare asteroid that traces out a horseshoe shape relative to Earth, the Jet Propulsion Laboratory (JPL) said on Friday.Unlike most near-Earth asteroids (NEAs) that have eccentric, or egg-shaped, orbits that take the asteroids right through the inner solar system, the new object has an orbit that is almost circular such that it cannot come close to any other planet in the solar system except Earth, JPL said.However, even though the asteroid rides around with Earth, it never gets that close, said JPL in Pasadena, Los Angeles.As the asteroid approaches Earth, the planet's gravity causes the object to shift back into a larger orbit that takes longer to go around the sun than Earth. Alternately, as Earth catches up with the asteroid, the planet's gravity causes it to fall into a closer orbit that takes less time to go around the sun than Earth, according to JPL.The asteroid therefore never completely passes our planet. This slingshot-like effect results in a horseshoe-shaped path as seen from Earth, in which the new object, designated 2010 SO16, takes 175 years to get from one end of the horseshoe to the other, JPL said."The origins of this object could prove to be very interesting, " said Amy Mainzer of JPL, the principal investigator of NEOWISE, which is the asteroid- and comet-hunting portion of the WISE survey mission. "We are really excited that the astronomy community is already finding treasures in the NEOWISE data that have been released so far."JPL manages and operates the WISE for NASA's Science Mission Directorate, Washington.

SAN FRANCISCO, March 21 (Xinhua) -- Microsoft on Monday sued Barnes & Noble, claiming patent infringement by the largest book retailer in the United States.Microsoft said it filed legal actions on Monday in both the U.S. International Trade Commission and the U.S. District Court of the Western District of Washington against Barnes & Noble, as well as Foxconn and Inventec, two manufacturers of Barnes & Noble's devices.According to Microsoft, the actions focus on the patent infringement by Barnes & Noble's Nook e-reader and tablet, both of which run Google's Android operating system.The patents at issue cover a range of functionality embodied in Android devices that are essential to the user experience, including natural ways of interacting with devices by tabbing through various screens to find the information they need, surfing the Web more quickly and interacting with documents and e-books, Microsoft said in a press release."The Android platform infringes a number of Microsoft's patents, and companies manufacturing and shipping Android devices must respect our intellectual property rights," Horacio Gutierrez, Microsoft's corporate vice president and deputy general counsel, was quoted by the press release as saying.Writing in a separate company blog post, Gutierrez said that the latest actions bring to 25 the total number of Microsoft patents in litigation for infringement by Android smartphones, tablets and other devices.He noted that Microsoft has established a licensing program to address Android's ongoing infringement, and leading Android smartphone manufacturer HTC has taken a license under this program.Amazon.com also signed a patent license with Microsoft last year covering its Kindle e-reader, he added."Unfortunately, after more than a year of discussions, Barnes & Noble, Foxconn and Inventec have so far been unwilling to sign a license, and therefore, we have no other choice but to bring legal action to defend our innovations," Gutierrez said in the blog post.
