SAN FRANCISCO, Aug. 23 (Xinhua) -- The amount of malware targeted at devices based on Google's Android platform surged 76 percent in the second quarter over the previous three months in 2011, making it the most attacked mobile operating system, computer security firm McAfee said on Tuesday.A new McAfee study found that in the second quarter, Android- based malware surpassed Nokia's Symbian as the most popular target for mobile malware developers.While Symbian and Java ME, a platform designed for mobile devices and other embedded systems, remain the most targeted to date, the rapid rise in Android malware indicates that the platform could become an increasing target for cyber criminals McAfee said.Models pose with the new Samsung Galaxy S Android smartphone during its launch ceremony at the headquarters of Samsung Electronics in Seoul in this June 8, 2010 file photograph.It warned that the attacks on Android platform could affect everything from calendar apps, to text messages, and even a fake Angry Birds updates.According to the study, malware on mobile platforms is increasing steadily, often mimicking the same code as personal computer-based threats, as vast amount of personal and business data are now found on user's smartphones and other mobile devices."This year we've seen record-breaking numbers of malware, especially on mobile devices, where the uptick is in direct correlation to popularity," Vincent Weafer, senior vice president of McAfee Labs, said in a statement."Overall attacks are becoming more stealth and more sophisticated, suggesting that we could see attacks that remain unnoticed for longer periods of time," he noted.

DAMASCUS, Sept. 21 (Xinhua) -- The national archeological expedition recently discovered a gigantic building built with large-size hewn stones that date back to the Roman era, Syrian Arab News Agency (SANA) said Wednesday.The building, the thickness of its walls up to 1.5 meters, was found at Qumet Nibal site in the northeastern province of Raqqa, said SANA.Ibrahim Kheir Bek, head of the archeological department in the area, told SANA that the excavation unearthed a 6-meter-long entrance to the building, adding that works are still underway in the site.A day earlier, the national archeological expedition discovered a mosaic dating back to the 6th century A.D. in northeast Syria, SANA said, adding that the rectangular mosaic was found at Hwaija Halawa site on the banks of al-Assad Lake in Raqqa province.Ayham al-Fakhri, head of the national expedition, was quoted by SANA as saying that the expedition uncovered 58 square meters of the mosaic with various colorful geometric shapes.

WASHINGTON, Aug. 11 (Xinhua) -- The unique fossils of an adult plesiosaur and its unborn baby may provide the first evidence that these ancient animals gave live birth like mammals, according to a new study to be published Friday in the journal Science.The 78-million-year-old, 15.4-foot-long (4.7-meter-long) adult specimen is a Polycotylus latippinus, one of the giant, carnivorous, four-flippered reptiles that lived during the Mesozoic Era.Dr. Robin O'Keefe of Marshall University in West Virginia and Dr. Luis Chiappe, Dinosaur Institute director of the Natural History Museum in Los Angeles County, have determined that it is the fossil of an embryonic marine reptile contained within the fossil of its mother.The embryonic skeleton contained within shows much of the developing body, including ribs, 20 vertebrae, shoulders, hips, and paddle bones.O'Keefe and Chiappe have also determined that plesiosaurs were unique among aquatic reptiles in giving birth to a single, large offspring, and that they may have lived in social groups and engaged in parental care.Although live birth has been documented in several other groups of Mesozoic aquatic reptiles, no previous evidence of it has been found in the important order of plesiosaurs."Scientists have long known that the bodies of plesiosaurs were not well suited to climbing onto land and laying eggs in a nest," O'Keefe said."So the lack of evidence of live birth in plesiosaurs has been puzzling. This fossil documents live birth in plesiosaurs for the first time, and so finally resolves this mystery."

SAN FRANCISCO, Sept. 22 (Xinhua) -- Former eBay Chief Executive Officer and California governor candidate Meg Whitman on Thursday was named Hewlett-Packard's new CEO, replacing Leo Apotheker who served 11 months on the job."We are fortunate to have someone of Meg Whitman's caliber and experience step up to lead HP," said the California-based company in a statement."We are at a critical moment and we need renewed leadership to successfully implement our strategy and take advantage of the market opportunities ahead," said the troubled tech giant.It noted that the job of the HP CEO now requires additional attributes to successfully execute on the company's strategy, adding Whitman "has the right operational and communication skills and leadership abilities to deliver improved execution and financial performance.""I am honored and excited to lead HP. I believe HP matters -- it matters to Silicon Valley, California, the country and the world," said Whitman in a statement.Whitman, 55, joined the HP board in January and served as president and CEO of eBay from 1998 to 2008, when she led the company through its initial public offering and massive growth.During her last years at eBay, she is blamed for not being able to halt the sales slowdown and overpaying for the 2005 acquisition of Skype with 4.1 billion dollars. In 2009, Skype was sold by eBay at a valuation of 2.75 billion dollars.Whitman won the Republican nomination for governor of California in 2010. She lost the election to Gov. Jerry Brown after spending more than 140 million dollars of her own fortune on the campaign. EnditemHP said the appointments are effective immediately, following the decision that Apotheker stepped down as president and CEO and resigned as a director of the company.Multiple U.S. media reported on Wednesday that Apotheker was to be ousted, sending HP shares soaring on the market and in the after-hour trading.Apotheker, 58, was named HP CEO 11 months ago to replace Mark Hurd, who was ousted due to a scandal over a personal relationship with a company contractor and then became co-president of Oracle. Before HP, Apotheker had served as CEO of German software giant SAP for 10 months.On Aug. 18, Apotheker announced that HP will shut down its mobile business, spin off its core personal computer business and transfer into a cloud-based software and services provider for businesses including a 10.3 billion-dollar acquisition of British software company Autonomy.Shares of the company plunged 20 percent the following day, the worst one-day loss since Black Monday in 1987.On Sept. 30, 2010, the day before Apotheker's appointment as HP CEO, the tech giant's stock closed at 42.04 dollars. On Tuesday, the price closed at 22.47 dollars, a decrease of 46.6 percent in less than a year.On Monday, HP was reported to begin sending over 500 employees pink slips in the WebOS division, after announcing to stop making WebOS devices in August.

BEIJING, Sept. 21 (Xinhuanet) -- China will launch an unmanned module next week, paving the way for a planned space station, a spokesman for the space program said on Tuesday.Tiangong-1, or "Heavenly Palace 1", will blast off from Jiuquan Satellite Launch Center in Gansu province between Sept 27 and 30, the spokesman said.The 8.5-ton module, and the Long March II-F rocket that will carry it skyward, were positioned onto the launch pad on Tuesday, signaling that the project has entered the final preparation stage."Scientists will conduct final tests in the next few days before injecting propellants for the launch," Cui Jijun, director of the Jiuquan Satellite Launch Center, said.The program spokesman said that Tiangong-1 will serve as "a target spacecraft" for rendezvous and docking experiments.It will also work as "a platform to test long-term unmanned and short-term manned operations", he said.Technical and medical experiments will provide crucial data ahead of the building of the space station (scheduled for 2020).Three rendezvous and docking experiments will be conducted.An unmanned Shenzhou-VIII craft will be launched later this year to dock with Tiangong-1. In 2012, Shenzhou IX and Shenzhou X will blast off to complete at least one manned docking.Jiao Weixin, a space scientist at Peking University, said that rendezvous and docking - vital maneuvers for manned programs - are hard to master."Rendezvous and docking are difficult because it is like asking two racing cars to keep a distance of 1 meter between them," he said.The mission requires two craft, traveling at speeds of 28,000 km/h, to enter the same orbit and connect with precision, he said.The China Manned Space Engineering Office rescheduled the launch of Tiangong-1 after the failed launch of an experimental orbiter last month.The spokesman said that the carrier rocket to blast off with Tiangong-1 atop has been modified.Only the United States and Russia have mastered rendezvous and docking technology, said Pang Zhihao, deputy editor-in-chief of the magazine Space International.Spacecraft developed by Europe and Japan have utilized US and Russian technology to dock with the International Space Station, he added.
