HONG KONG, Oct. 13 (Xinhua) -- Computer and electronic device maker Lenovo, listed in both Hong Kong and New York, has replaced Dell to become the world's second largest personal computer company, Lenovo said Thursday.Lenovo made the remarks in a statement, citing figures released by International Data Corporation (IDC), a global provider of business intelligence for the consumer technology market.Following five quarters as the fastest-growing PC maker among the world's top vendors, the preliminary IDC data reported that Lenovo has achieved record market share of around 13.7 percent and record quarterly shipment volume of some 12.6 million units.Lenovo CEO Yang Yuanqing said his company had surpassed two competitors to capture the No. 2 spot in worldwide PCs in just two quarters and it was the highest rank that Lenovo has achieved in worldwide PC sales.Given current competitive environment, the new achievement positioned Lenovo as a strong challenger to ultimately become the global market leader, Yang said in the statement."We are growing in the enterprise and the consumer space. And our customers know we are fully committed to the PC market for the long term," he said.At the same time, the Chinese multinational would continue investing in innovative products that would help drive the convergence of technologies and services across all four screens -- smart phones, tablets, PCs and smart TV, Yang said."We must deliver a great user experience across all platforms to achieve our goal and become the leading personal technology company in the world."Lenovo is a personal technology company and a global Fortune 500 company with annual sales worth 21 billion U.S. dollars. It serves customers in more than 160 countries and regions.

WASHINGTON, Dec. 20 (Xinhua) -- NASA's Kepler mission has discovered the first Earth-size planets orbiting a sun-like star outside our solar system, the U.S. space agency announce Tuesday.The planets, called Kepler-20e and Kepler-20f, are too close to their star to be in the so-called habitable zone where liquid water could exist on a planet's surface, but they are the smallest exoplanets ever confirmed around a star like our sun, according to NASA.The discovery marks the next important milestone in the ultimate search for planets like Earth. The new planets are thought to be rocky. Kepler-20e is slightly smaller than Venus, measuring 0.87 times the radius of Earth. Kepler-20f is slightly larger than Earth, measuring 1.03 times its radius. Both planets reside in a five-planet system called Kepler-20, approximately 1, 000 light-years away in the constellation Lyra.Kepler-20e orbits its parent star every 6.1 days and Kepler-20f every 19.6 days. These short orbital periods mean very hot, inhospitable worlds. Kepler-20f, at 800 degrees Fahrenheit, is similar to an average day on the planet Mercury. The surface temperature of Kepler-20e, at more than 1,400 degrees Fahrenheit, would melt glass."The primary goal of the Kepler mission is to find Earth-sized planets in the habitable zone," said Francois Fressin of the Harvard-Smithsonian Center for Astrophysics, lead author of a new study published in the journal Nature. "This discovery demonstrates for the first time that Earth-size planets exist around other stars, and that we are able to detect them."The Kepler-20 system includes three other planets that are larger than Earth but smaller than Neptune. Kepler-20b, the closest planet, Kepler-20c, the third planet, and Kepler-20d, the fifth planet, orbit their star every 3.7, 10.9 and 77.6 days. All five planets have orbits lying roughly within Mercury's orbit in our solar system. The host star belongs to the same G-type class as our sun, although it is slightly smaller and cooler.

SHENYANG, Nov. 17 (Xinhua) -- A MD-90 aircraft left the northeastern city of Shenyang for its American home on Thursday, ending the service of the last McDonnell-Douglas jet for Chinese airlines.Chinese carriers will no longer operate MD-made jets due to growing market demands, said Lu Changchun, deputy general manager with the north China branch of China Southern Airlines, which has operated the MD-90 jet for over a decade.MD-90 jets were involved in no accidents during the decade-long-service in China, so safety concerns did not lead to their retirement, Lu said, adding about 1,000 MD-90 jets are still flying around the world.Lu, however, admitted that supply of aircraft materials was affected as the production line of MD jets shrank, after McDonnell-Douglas Cooperation was merged into Boeing in 1997.MD jets were replaced mainly because Chinese airlines need new models to accommodate air travel demands fueled by the economic boom, Lu said.The north China branch of China Southern Airlines also announced Thursday the retirement of five A300-600R planes, which are replaced by A320 family jets. China Southern Airlines began flying an Airbus A380 superjumbo in China in October.China's domestic air travel market is predicted to grow 13.9 percent annually by 2014 and transport 379 million domestic air passengers, which will make the country the world's second-largest air travel market after the United States, according to a report released by the International Air Transport Association.Back in the 1990s, a Shanghai-based aircraft maker assembled two MD-90 jets in China, Lu said, adding the two jets retired this year.Change of jets model serves the strategic transformation of China Southern Airlines and meets the market demands, Lu said.Li Jiaxiang, chief of China's civil aviation administration, estimated that over 1.5 trillion yuan (235 billion U.S. dollars) will be invested in the civil aviation industry by 2015, adding about 2,000 aircraft to the country's fleet.Commercial Aircraft Corporation of China, producer of China's first self-developed jumbo jet, the C919, has announced that it will complete the design for the passenger plane in 2012. The jet is expected to take off in 2014 and put into service in 2016.

BEIJING, Nov. 9 (Xinhuanet) -- Routine bowel screening can cut deaths from bowel cancer by 27 percent, a latest Scottish study finds.The result was presented at the National Cancer Research Institute's (NCRI) conference in Liverpool. Funded by the Scottish government's health department, the study involved over 370,000 people aged 50 to 69 from Scotland. Every participant was given a FOBt (faecal occult blood test) kit-- which was used to collect their stool samples-- every two years between 2000 and 2007. The samples were sent to a laboratory for hidden traces of blood test.Under the monitor of the researchers, the participants saw a 27 percent fewer bowel cancer deaths than a similar number of people from Scotland uninvolved in the trial."For the first time, we can see the effects of an FOBt-based colorectal cancer screening program in the real world of the NHS," cheered author Robert Steele from the Bowel Screening Research Centre in Dundee.According to a BBC report, when bowel cancer is detected at the earliest stage, 90% of patients survive for at least five years. After the disease has spread, the survival rate is just 6%.
