SAN FRANCISCO, June 1 (Xinhua) -- Microsoft on Wednesday gave a preview of its next-generation operating system code-named "Windows 8."The software giant introduced the successor to Windows 7 at the ninth edition of The Wall Street Journal's Digital: All Things Digital in Rancho Palos Verdes, California, some 48 km south of Los Angeles.With an interface quite different from legacy Windows, Windows 8 looks more like Windows Phone 7 and features an app management from Windows mobile operating system. It is the first major attempt by Microsoft to expand a mobile operating system to desktop status, and is expected to be touch-friendly and work seamlessly on desktops, laptops and tablet computers.For legacy Windows users, they need to swipe up from the bottom of the screen to get to the Windows 7-based view. Microsoft said the new system will be compatible with all Windows 7 logo PCs, software and peripherals.During the demonstration, Steven Sinofsky, Microsoft's head of Windows, also said the importance of not abandoning the established technologies from the traditional PC. "The mouse and the keyboard aren't evil. They're just tools. There are a number of applications that require the greater precision offered by the mouse." said Sinofsky.Sinofsky did not say when Windows 8 would be available.Although there are some tablets running Microsoft's current Windows 7 operating system, the software giant has been criticized for failing to adequately respond to the fast growth of tablet computers, like Apple's iPad.

BEIJING, Sept. 10 (Xinhua) -- China will start "overall and thorough" safety checks on offshore oil exploration and production to eliminate risks in the wake of oil spills in the country's northern Bohai Bay, the work safety authority said Saturday.The checks, which starts from September 10 to December 10, will be applied to all offshore oil exploration and production, the State Administration of Work Safety said in a circular addressed to oil companies on its website.The companies include China National Petroleum Corporation, China Petrochemical Corporation, China National Offshore Oil Corporation, ConocoPhillips China, Kerr-McGee China Petroleum Ltd., Roc Oil (Bohai) Company, CACT Operators Group, Husky Oil China Ltd., Shanghai Petroleum Co., Energy Development Corporation (EDC) China and Tincy Group Energy, the statement said.The administration urged these enterprises to conduct self-examinations on their offshore fixed and mobile platforms and floating production storage and offloading units, submarine pipelines and onshore oil terminals in two months till November 10. They should file result reports before November 20.The authority's officials, joined by experts, will launch inspections from late November, the statement said. The checks cover well control amid drilling operation, safety management during production, facilities, and management over extreme weather, it added.The order came after the State Council on Wednesday called for strengthened monitoring and management of the marine environment as well as safety checks over the country's ocean oil fields to toughen safety measures and erase potential risks.The decision was made after oil spills at an offshore oil field run by U.S. oil giant ConocoPhillips have polluted more than 5,500 square km of sea water in the Bohai Bay since June.The central government also imposed restricts on new petrochemical projects and ban reclamation projects in the bay for environmental concerns.China has stepped up efforts to explore and materialize offshore resources to seek more dependence of the marine industries as a strategic development move. In its 12th Five-Year Plan, the government advocates greater scientific and systematic utilization of marine resources and coastal areas as energy demand soars.

BEIJING, Sept. 28 (Xinhuanet) -- The unmanned Shenzhou VIII, part of China's first spacecraft rendezvous and docking mission, will be launched in early November. Niu Hongguang, deputy commander-in-chief of the program, said on Tuesday the launch has not been affected by the postponed lift-off of the Tiangong-1 space module. Tiangong-1 was to enter a low orbit around Earth at the end of August before being met by Shenzhou VIII. However, the departure was pushed back after a satellite failure on Aug 18. Out of safety concerns, Niu said mission commanders ordered a halt to testing at Jiuquan Satellite Launch Center on Tiangong-1 and its carrier rocket, Long March II-F T1. China Aerospace Science and Technology Corp, which designed and made the rocket carrier that failed to launch, formed an expert panel to investigate and made modifications. A successful launch of a communication satellite on Sept 19 using the Long March II-C showed the measures worked, Niu said, adding: "We now have confidence in the launch of Tiangong-1." The module is a "simplified" space lab that will not only be a docking target, but will also work as a space experimental platform. It will be unmanned for most of its two years of use, although astronauts will spend time onboard for short periods. After Shenzhou VIII, the country will launch Shenzhou IX and Shenzhou X next year to rendezvous and dock with Tiangong-1. Niu confirmed Shenzhou X will be manned. Tiangong-1 can accommodate two to three astronauts. "Whether Shenzhou IX will be manned is up to the results of the first rendezvous and docking mission," he said. The rocket carrier with Tiangong-1 atop stands 52 meters tall, with a takeoff weight of 493 tons. Tiangong-1 was scheduled for launch in between Sept 27 and 30, but due to weather forecasts that predicted a cold air mass would move into the area of Jiuquan Satellite Launch Center, it is believed that conditions on Thursday and Friday will be suitable for takeoff.

LONDON, Sept. 22 (Xinhua) -- A British publisher on Thursday issued an "unauthorized autobiography" of the founder of the controversial Wikileaks website Julian Assange.Assange became a global figure after he published 250,000 secret United States diplomatic cables on his Wikileaks website, which became a serious embarrassment to the American government.He was then accused by two women of rape when he was in Sweden. Swedish police said they wanted to question him, and issued a European Arrest Warrant in 2010 for him.Assange, 40, denies the allegations and surrendered himself to police in London at the end of 2010, and the Swedish authorities applied for his extradition to face questioning.Assange fought the extradition bid in the English courts, fearing that he could face further extradition from Sweden to the United States where he could face criminal charges related to the publishing of the secret cables, but failed.He appealed against the extradition ruling in July and a final decision on the case will be made by senior English judges, probably before Christmas.Assange agreed to cooperate with Edinburgh-based publisher Canongate in publishing an autobiography and had 50 hours of interviews with a ghostwriter between January and March this year, while he was on bail awaiting an outcome of the extradition hearings.He received a 500,000 pound advance (about 768,000 U.S. dollars) for the book.Publisher's spokesman Liz Sich told Xinhua Thursday, "It's an unauthorized autobiography -- it is his words. He was contracted to write his autobiography in December; a ghostwriter was assigned to it, approved by the publisher and Julian and an intense amount of work was done in the first three months of 2011. The first draft was delivered on schedule at the end of March. After that there was an hiatus and nothing happened; in June Julian decided he wanted to tear up the contract."Assange has opposed publication, but Sich said, "It is very much Julian's words, it is written in the first person. He didn't want it to be published but he was in breach of his contract. He couldn't pay the advance back because he had used it to pay his lawyers."The book is available only in English at the moment, but a Dutch publisher and a Turkish publisher said they would print translations in their languages, and other foreign language editions are also likely.

WASHINGTON, June 15 (Xinhua) -- Using the deepest X-ray image ever taken, astronomers found the first direct evidence that massive black holes were common in the early universe, the U.S. National Aeronautics and Space Administration (NASA) said Wednesday in a statement.The discovery from NASA's Chandra X-ray Observatory shows that very young black holes grew more aggressively than previously thought, in tandem with the growth of their host galaxies.By pointing Chandra at a patch of sky for more than six weeks, astronomers obtained what is known as the Chandra Deep Field South (CDFS). When combined with very deep optical and infrared images from NASA's Hubble Space Telescope, the new Chandra data allowed astronomers to search for black holes in 200 distant galaxies, from when the universe was between about 800 million to 950 million years old."Until now, we had no idea what the black holes in these early galaxies were doing, or if they even existed," said Ezequiel Treister of the University of Hawaii, lead author of the study to appear Thursday in journal Nature. "Now we know they are there, and they are growing like gangbusters."The super-sized growth means that the black holes in the CDFS are less extreme versions of quasars -- very luminous, rare objects powered by material falling onto supermassive black holes. However, the sources in the CDFS are about a hundred times fainter and the black holes are about a thousand times less massive than the ones in quasars.The observations found that between 30 and 100 percent of the distant galaxies contain growing supermassive black holes. Extrapolating these results from the small observed field to the full sky, there are at least 30 million supermassive black holes in the early universe. This is a factor of 10,000 larger than the estimated number of quasars in the early universe."It appears we've found a whole new population of baby black holes," said co-author Kevin Schawinski of Yale University. "We think these babies will grow by a factor of about a hundred or a thousand, eventually becoming like the giant black holes we see today almost 13 billion years later."
