SAN FRANCISCO, April 28 (Xinhua) -- Cisco Systems Inc., world's largest maker of computer-networking equipment, on Thursday brought up an early retirement offer to its employees in the United States and Canada, in a move to cut costs and restructure the company.The voluntary plan applies to employees who are at least 50 years old and have a combined age and years of service at Cisco for at least 60 as of July 8, the company said in a memo sent to employees."Cisco employs a variety of different methods to control costs and align investment dollars, and offering this voluntary early retirement program to those eligible employees in the U.S. and Canada is part of our ongoing commitment to responsible business management," the company said in a statement.Cisco gave no details on the costs it would save and the number of employees eligible for the plan.Earlier this month, Cisco CEO John Chambers warned that "tough decisions" would be made to preserve profitability as government budget pressure has been costing the company orders and slowing its sales growth.On April 12, Cisco announced to shut down its Flip Video camcorder business to restructure its business and support its key priorities.

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.

BEIJING, Feb. 10 (Xinhua) -- China's drought control authorities announced Thursday that hours of snowfall and irrigation have eased to some extent the severe drought in parts of the nation.Rapid spreading of the dry spell in the country's winter wheat producing regions has been curbed by wide-spread snowfall in the areas along the Yangtze, Huaihe and Yellow rivers and in the country's northern part on Wednesday and Thursday, the Office of State Flood Control and Drought Relief Headquarters said in a statement on its website.Drought-hit areas in Henan and Anhui, which are two major wheat-producing provinces, were reduced by 6.3 million mu (420,000 hectares) and 4.1 million mu, respectively, from Wednesday, the statement said. The agency added that irrigation also contributed to easing the effects of the drought.The statement said that as of Thursday, eight drought-hit provinces had irrigated 143 million mu of drought-affected wheat producing areas, which accounts for 52 percent of the combined winter wheat producing areas in the provinces. The eight provinces include the territories of Shandong, Henan, Hubei, Anhui, Shanxi, Shaanxi, Gansu and Jiangsu.As of 3 p.m. Thursday, the drought had affected 101.28 million mu of crops nationwide and left 2.81 million people and 2.57 million heads of livestock short of drinking water, said the statement.Cloud seeding on Wednesday and Thursday during a recent cold front, also helped alleviate drought in some regions, according to a report posted on the website of the China Meteorological Administration on Thursday.The report also said that the artificial precipitation had mitigated the shortage of moisture in the soil in parts of Henan and Anhui. The situation is expected to improve as the rain and snow continues.However, experts urged more measures from local governments to ensure winter wheat production since the current precipitation is not adequate to "completely ease the drought", the report said.

SAN FRANCISCO, April 28 (Xinhua) -- Microsoft Corp. on Thursday posted quarterly revenue and earnings that both beat analysts' expectations.In its fiscal 2011 third quarter ended on March 31, the software giant reported revenue of 16.43 billion U.S. dollars, up 13 percent from the same period a year earlier.Net income and earnings per share were 5.23 billion dollars and 61 cents, representing increases of 31 percent and 36 percent respectively year-on-year.Analysts had expected earnings of 56 cents per share on revenue of 16.19 billion dollars, according to Thomson Reuters."We delivered strong financial results despite a mixed PC environment, which demonstrates the strength and breadth of our businesses," Peter Klein, chief financial officer at Microsoft, said in a statement."Consumers are purchasing Office 2010, Xbox and Kinect at tremendous rates, and businesses of all sizes are purchasing Microsoft platforms and applications," he added.Revenue at four of Microsoft's five major divisions posted double-digit growth in the quarter, indicating the increase of technology spending by enterprises as well as strong demand for the company's entertainment products.The entertainment and devices division saw the biggest revenue growth of 60 percent, which according to Microsoft, were driven by strong demand for its Kinect hands-free motion control system for Xbox 360 and continued strong sales of Xbox 360 console.However, revenue for the division of the company's flagship Windows operating system dropped 4 percent in the quarter, which Microsoft said was "in line with the PC trends."The performance of the Windows division may fuel new concerns that Microsoft's dominance in software for PCs is being threatened by Apple's iPad and tablet computers running other operating systems, some analysts noted.

LOS ANGELES, April 12 (Xinhua) -- With the help of NASA Telescopes, astronomers have uncovered one of the youngest galaxies in the distant universe, with stars that formed 13.5 billion years ago, the Jet Propulsion Laboratory (JPL) announced on Tuesday.The finding addresses questions about when the first galaxies arose, and how the early universe evolved, JPL noted in a press release.Infrared data from both the Hubble Space Telescope and the post- coolant, or "warm," phase of NASA's Spitzer Space Telescope mission revealed that the galaxy's stars are quite mature, which means they must have formed when the universe was just a toddler, said JPL in Pasadena, Los Angeles.This challenges theories of how soon galaxies formed in the first years of the universe and could even help solve the mystery of how the hydrogen fog that filled the early universe was cleared, according to astronomers involved in the study.This galaxy is not the most distant ever observed, but it is one of the youngest to be observed with such clarity, JPL said.Normally, galaxies like this one are extremely faint and difficult to study, but, in this case, nature has provided the astronomers with a cosmic magnifying glass, JPL said.The galaxy's image is being magnified by the gravity of a massive cluster of galaxies parked in front of it, making it appear 11 times brighter. This phenomenon is called gravitational lensing."Without this big lens in space, we could not study galaxies this faint with currently available observing facilities," said Eiichi Egami of the University of Arizona in Tucson. "Thanks to nature, we have this great opportunity to see our universe as it was eons ago."The findings may help explain how the early universe became " reionized," according to JPL."Seeing a galaxy as it appeared near the beginning of the universe is an awe-inspiring feat enabled by innovative technology and the fortuitous effect of gravitational lensing," Jon Morse, NASA's Astrophysics Division director at the agency's headquarters in Washington, said in the release."Observations like this open a window across space and time, but more importantly, they inspire future work to one day peer at the stars that lit up the universe following the big bang."
