LOS ANGELES, May 23 (Xinhua) -- NASA's Gravity Recovery And Interior Laboratory spacecraft (Grail) will begin final preparations for a launch on a Moon mission in late summer, the Jet Propulsion Laboratory (JPL) said on Monday.The dynamic duo will orbit the moon to determine the structure of the lunar interior from crust to core and to advance understanding of the thermal evolution of the moon, according to JPL in Pasadena, Los Angeles.After arriving at the Astrotech payload processing facility in Titusville, Florida last week, the Grail twins, known as Grail-A and Grail-B, were removed from their shipping containers Monday. Later this week, they will begin functional testing to verify their state of health, said JPL.The twins were shipped from Lockheed Martin Space Systems, Denver.Over the next four months at the Astrotech facility, the spacecraft will undergo final testing, fueling and packaging in the shroud that will protect them as the Delta II launch vehicle lifts them into space. The spacecraft will then be transported to the Cape Canaveral Air Force Station for installation atop the rocket that will carry them toward the moon, JPL said."We're only a few full moons away from a mission that will reveal clues not only into the history of the moon and Earth, but will provide important data for future lunar exploration," said Maria Zuber, Grail's principal investigator, based at the Massachusetts Institute of Technology.Grail will be carried into space aboard a United Launch Alliance Delta II Heavy rocket lifting off from Launch Complex-19 at the Cape Canaveral Air Force Station in Florida. The launch period opens Sept. 8, 2011, and extends through Oct. 19. For a Sept. 8 liftoff, the launch window opens at 5:37 a.m. PDT (8:37 a.m. EDT) and remains open through 6:16 a.m. PDT (9:16 a.m. EDT).Grail-A and Grail-B will fly in tandem orbits around the moon for several months to measure its gravity field in unprecedented detail.The mission will also answer longstanding questions about Earth' s moon, and provide scientists a better understanding of how Earth and other rocky planets in the solar system formed, according to JPL, which manages the Grail mission.

BEIJING, Jan. 24 (Xinhua) -- China's top economic planner said Monday that price supervision and control measures have achieved steady progress with 2010's Consumer Price Index, slightly exceeding the target ceiling by 0.3 percentage points to hit 3.3 percent.To rein in soaring commodities prices, joint efforts have been made to manage inflation expectations, promote production, ensure supplies and strengthen price supervision in 2010, said the National Development and Reform Commission (NDRC) in an online statement.Prices of necessities accelerating during the second half of 2010 have been contained with vegetable prices down 9.4 percent in December from the previous month last year, it said.Further, prices of edible vegetable, pork, egg, sugar,liquefied petroleum gas and clothing also decreased significantly in December month on month, the statement said.To cope with rising prices beginning in July 2010, especially prices of basic supplies, the central government promptly introduced joint inter-ministerial meetings to discuss price controls among 17 ministries and ordered local governments to establish the same mechanism, it noted.Local governments have worked on improving agricultural facilities, especially in south China's Hainan province, to increase vegetables supplies for northern cities over the past year, the statement said.The statement forecasts that vegetable planting areas in 2010's autumn and winter will increase 530,000 hectares year on year, sending output to 337 million tonnes.To ensure production and supply, departments have worked to reduce fertilizer exports and promote links between production areas and purchasing areas, it added.Further, relevant authorities also took measures to stabilize prices of electricity and coal, and to ensure smooth transportation of agricultural produce.Authorities also granted temporary subsidies and raised basic wages and minimum living subsidies for urban and rural residents to guarantee people's daily life.

WASHINGTON, May 2 (Xinhua) -- Rice originated in China, a team of U.S. genome researchers has concluded in a study tracing back thousands of years of evolutionary history through large-scale gene re-sequencing.Their findings, which appear Monday in the latest issue of the Proceedings of the National Academy of Sciences (PNAS), indicate that domesticated rice may have first appeared as far back as approximately 9,000 years ago in the Yangtze Valley of China. Previous research suggested domesticated rice may have two points of origin -- India as well as China.Asian rice, Oryza sativa, is one of world's oldest crop species. It is also a very diverse crop, with tens of thousands of varieties known throughout the world. Two major subspecies of rice -- japonica and indica -- represent most of the world's varieties. Sushi rice, for example, is a type of japonica, while most of the long-grain rice in risottos are indica.Because rice is so diverse, its origins have been the subject of scientific debate. One theory -- a single-origin model -- suggests that indica and japonica were domesticated once from the wild rice O. rufipogon.Another -- a multiple-origin model -- proposes that these two major rice types were domesticated separately and in different parts of Asia. The multiple-origin model has gained currency in recent years as biologists have observed significant genetic differences between indica and japonica, and several studies examining the evolutionary relationships among rice varieties supported more than domestication in both India and China.In the PNAS study, the researchers re-assessed the evolutionary history, or phylogeny, of domesticated rice using previously published datasets, some of which have been used to argue that indica and japonica rice have separate origins. Using more modern computer algorithms, however, the researchers concluded these two species have the same origin because they have a closer genetic relationship to each other than to any wild rice species found in either India or China.In addition, the study's authors examined the phylogeny of domesticated rice by re-sequencing 630 gene fragments on selected chromosomes from a diverse set of wild and domesticated rice varieties. Using new modeling techniques, which had previously been used to look at genomic data in human evolution, their results showed that the gene sequence data was more consistent with a single origin of rice.In the study, the investigators also used a "molecular clock" of rice genes to see when rice evolved. Depending on how the researchers calibrated their clock, they pinpointed the origin of rice at possibly 8,200 years ago, while japonica and indica split apart from each other about 3,900 years ago. The study's authors pointed out that these molecular dates were consistent with archaeological studies.Archaeologists have uncovered evidence in the last decade for rice domestication in the Yangtze Valley beginning approximately 8, 000 to 9,000 years ago while domestication of rice in the India's Ganges region was around about 4,000 years ago."As rice was brought in from China to India by traders and migrant farmers, it likely hybridized extensively with local wild rice," explained New York University biologist Michael Purugganan, one of the study's co-authors. "So domesticated rice that we may have once thought originated in India actually has its beginnings in China."

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.
