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.

SYDNEY, Jan. 25 (Xinhua) -- Huawei Technologies, on Monday asked a U.S. District Court to prevent Motorola from illegally transferring Huawei's intellectual property (IP) to Nokia Siemens Networks ("NSN"), officials of Huawei told Xinhua in Sydney, Australia on Tuesday.As a leading player in providing next generation telecommunications network solutions, Huawei took this action as NSN seeks to complete its 1.2 billion U.S. dollars acquisition of Motorola's wireless network business.Since 2000, Huawei and Motorola have had a cooperative relationship in the radio access network and core network businesses, where Motorola has resold Huawei wireless network products to customers under the Motorola name. During this period, Motorola was provided with products and confidential Huawei IP developed by Huawei's team of more than 10,000 engineers.Since the July 2010 announcement by NSN of its purchase of Motorola's wireless network business, Huawei has tried to ensure that Motorola does not transfer this confidential information to NSN.According to officials of Huawei, Motorola's failure to adopt measures sufficient to ensure that Huawei's proprietary information remains confidential has compelled the company to file for the appropriate legal protection of its rights.The officials said Huawei respects the rights of intellectual property holders and is equally committed to the protection of its own innovations and intellectual property.Nearly half of Huawei's 100,000 plus employees are engaged in research and development and Huawei allocates an average of 10 percent of all revenues to R&D annually. By the end of 2010, Huawei had applied for 49,040 essential patents on a global basis.

BEIJING, Feb. 17 (Xinhua) -- The Communist Party of China (CPC) Central Committee on Thursday night hosted a gala to celebrate the traditional Lantern Festival.Chinese President and General Secretary of the CPC Central Committee Hu Jintao and eight other members of the Standing Committee of the Political Bureau of the CPC Central Committee attended the event, along with representatives from Beijing's intellectual circle.The eight CPC leaders included Wu Bangguo, Wen Jiabao, Jia Qinglin, Li Changchun, Xi Jinping, Li Keqiang, He Guoqiang and Zhou Yongkang.The gala was presided over by Li Changchun, who extended warm regards to the participants on behalf of the CPC Central Committee.Mentioning 2010 as an extraordinary year for China's development, Li said the CPC Central Committee, with Hu Jintao as the General Secretary, led the Party and nation to successfully host the Shanghai World Expo and Guangzhou Asian Games.

BEIJING, April 19 (Xinhuanet) -- Almost one year after the disastrous oil spill, scientists believe that the overall health of the Gulf of Mexico as nearly back to normal.However, the scientists restrain their optimism about nature's resiliency with the glaring blemishes out there. It's been nearly a year since BP's Gulf of Mexico oil spill began last April, triggering one of the world's worst environmental disasters. Nearly 5 million barrels of oil leaked from the ruptured Deepwater Horizon well during the months-long catastrophe.BP said last November that the disaster cost it nearly 40 billion U.S. dollars, according to a Guardian report.According to a BP survey of researchers, over three dozen scientists grade the Gulf's big picture health a 68 on average, using a 1-to-100 scale.That's just a few points below the 71 the same researchers gave last summer when asked what grade they would give the ecosystem before the spill. And it's an improvement from the 65 given back in October after months of the oil spill.
