SAN FRANCISCO, Sept. 13 (Xinhua) -- Microsoft released on Tuesday a test version of Windows 8 to developers, posing to regain ground of the tablet market dominated by Apple and Google.At its developer-focused BUILD conference held in Anaheim, California, the software giant handed out new Samsung tablet computers with a test version of the code-named "Windows 8," the first detailed preview of the system for developers and people outside Microsoft.Generally expected to be launched in fall 2012, Microsoft did not say when the system will ship or its price.Microsoft Windows President Steven Sinofsky introduces the new tablet running a test version of its touch-enabled Windows 8 at the Build conference in Anaheim, California September 13, 2011Featuring a home page filled with colorful application tiles, the new system boots up in seconds. Microsoft said the system will run on low-power ARM-based chips that power smartphones and tablets. Windows 8 also introduces a new "Metro style" interface, which run full-screen and users can multitask in two at a time."We reimagined Windows," said Steven Sinofsky, president of the Windows and Windows Live Division at Microsoft, in his keynote address to the thousands of developers in attendance. "From the chipset to the user experience, Windows 8 brings a new range of capabilities without compromise."Analysts said the new system is consumer-oriented and intuitive but it will take time to see whether it is an "iPad killer."As professionals and consumers began to spend more time on smartphones and tablets, Microsoft has not got a significant bite of the market, losing ground to Apple's iPad and devices running Google's Android system.

CAIRO, July 6 (Xinhua) -- Egypt's Central Administration of Agricultural Quarantine has denied again that the country's fenugreek seeds exported to Europe caused the E.coli infections which have claimed dozens of lives.The Egyptian authorities took and analyzed fenugreek seeds samples from the warehouse of the said Egyptian exporter and all results were negative by the strain, a statement posted on the official website of Egypt's Agricultural Ministry said on Wednesday."E.coli strain has not been reported in Egypt and no illness cases have been found," it added.If fenugreek seeds sprouts are suspected to be contaminated with E.coli pathogenic strain, it could be related to different handling processes, such as the re-packing or water used for sprouting, the statement said.The European Union (EU) on Tuesday agreed to ban the import of certain types of seeds from Egypt as Egyptian fenugreek seeds were reported to be linked with the outbreak of E.coli in Europe.The European Food Safety Authority (EFSA) published early Tuesday a report from its task force on the E.coli outbreaks in Germany and France, indicating that fenugreek seeds imported from Egypt is the most likely source of the outbreaks.The E.coli outbreak has killed over 50 people in Europe since it was first reported in late May.Russia's food safety watchdog Rospotrebnadzor has also banned the import of certain types of produce from Egypt over food safety concerns, a Russian official said on Wednesday.Egypt's Ministry of Agriculture refuted the claims of Egypt being the source of E.coli Friday.

SYDNEY, Aug. 16 (Xinhua) -- People sitting in front of TV for hours on end could shorten their life expectancy by almost five years, according to an Australian study published on Tuesday by the British Journal of Sports Medicine.Researchers from the University of Queensland estimate that for every hour adults spend in front of TV, their life expectancy shortens by almost 22 minutes.Those who watched six hours a day lived 4.8 years less than those who don't watch TV.The study is the first in Australia to look into how TV habits affect longevity.The Australian researchers found that watching TV could have a similar negative impact on life expectancy to that of obesity, smoking and low physical activity."People don't realize how it all adds up," the study's lead author Dr. Lennert Veerman told the Australian Associated Press (AAP)."They should try not to watch too much TV and find alternative things to do, preferably things that are light activities," Veerman said.The study was based on data from the Australian Diabetes, Obesity and Lifestyle study and asked more than 11,000 people aged over 25 about their weekly TV viewing time.The study found that in 2008 Australian adults watched 9.8 billion hours of TV."These findings suggest that substantial loss of life may be associated with prolonged TV viewing time among Australian adults," the study said."TV viewing time may have adverse health consequences that rival those of lack of physical activity, obesity and smoking; every single hour of TV viewed may shorten life by as much as 22 minutes," it said."With further corroborative evidence, a public health case could be made that adults also need to limit the time spent watching TV."Australians are recommended to spend at least 30 minutes a day doing moderate-intensity physical activity to reduce an increased risk of developing cardiovascular disease.

WASHINGTON, Aug. 18 (Xinhua) -- Black scientists were significantly less likely than their white counterparts to receive research funding from the National Institutes of Health (NIH), according to an analysis of data from 2000 to 2006.University of Kansas Professor of Economics Donna Ginther was the lead author on the study commissioned by the NIH, which will appear Friday in journal Science.The researchers found a 10 percentage point gap in research funding -- even after taking into consideration demographics, education and training, employer characteristics, NIH experience and research productivity. For example, for every 100 grants submitted to NIH, 30 grants from white applicants were funded, compared to 20 grants for black applicants.Applications for NIH funding go through peer review that considers the significance, innovation and approach of grant applications, the investigator(s) and the research environment. About half of the applications are determined to be worth scoring. Among those scored, budgets and NIH Institutes priorities determine which applications are funded. Priorities can vary by year and by Institute.The study found that applications from black researchers were less likely to be scored and on average had worse scores. After controlling for the score of the grant, there were no race or ethnicity differences in funding.Applicants self-identify race, ethnicity and gender, but that information is not available during the peer review. However, biographical facts that are included in the review materials can provide clues to the identity of the applicants.The research suggests it is possible that cumulative advantage may explain the funding differences."Small differences in access to research resources and mentoring during training or at the beginning of a career may accumulate to become large between-group differences," the paper says.Additionally, the paper suggests further research is needed to determine why black researchers are less likely to be funded.NIH Director Francis Collins and Principal Deputy Director Lawrence Tabak call the findings unacceptable and commit to immediate action by the NIH."NIH commissioned this study because we want to learn more about the challenges facing the scientific community and address them head on. The results of this study are disturbing and disheartening, and we are committed to taking action," said Collins in an accompanying commentary. "The strength of the U.S. scientific enterprise depends upon our ability to recruit and retain the brightest minds, regardless of race or ethnicity. This study shows that we still have a long way to go."NIH initiated the study in 2008 to determine if researchers of different races and ethnicities with similar research records and affiliations had similar likelihoods of being awarded a new NIH research project grant.

BEIJING, Sept. 9 (Xinhua) -- Lenovo Group, China's largest PC maker, said it aims to become the world's second-largest PC provider by the end of this year, China Daily reported Friday.The PC maker will take aggressive action to expand in the international PC market left by its competitors because of strategy adjustment, the English newspaper quoted Liu Chuanzhi, the board chairman of Lenovo, as saying.A few weeks ago, the world's biggest PC maker Hewlett-Packard Corp. said it will spin off its PC sector. Apple Inc's former CEO Steve Jobs resigned."The Chinese market is the starting point for Lenovo, but it won't be the only place Lenovo should put emphasis on. We will set up a more active strategy for expanding in overseas markets," Liu said.The PC maker has long been focusing on the global market. It purchased the PC division of the IBM Corp. a few years ago. In January, it announced a 175-million-U.S.-dollar joint venture with Japan's NEC Corp. In July, Lenovo completed its acquisition of Medion AG, a German multimedia and consumer electronics maker.
