WASHINGTON, June 6 (Xinhua) -- Forests in many regions are becoming larger carbon sinks thanks to higher density, U.S. and European researchers say in a new report.In Europe and North America, increased density significantly raised carbon storage despite little or no expansion of forest area, according to the study, led by Aapo Rautiainen of the University of Helsinki, Finland, and published Monday in the on- line, open-access journal PLoS One.Even in the South American nations studied, more density helped maintain regional carbon levels in the face of deforestation.The researchers analyzed information from 68 nations, which together account for 72 percent of the world's forested land and 68 percent of reported carbon mass. They conclude that managing forests for timber growth and density offers a way to increase stored carbon, even with little or no expansion of forest area."In 2004 emissions and removals of carbon dioxide from land use, land-use change and forestry comprised about one fifth of total emissions. Tempering the fifth by slowing or reversing the loss of carbon in forests would be a worthwhile mitigation. The great role of density means that not only conservation of forest area but also managing denser, healthier forests can mitigate carbon emission," says Rautiainen.

CANBERRA, June 6 (Xinhua) -- Australian beef is not to blame for a recent outbreak of E.coli in Japan, Meat and Livestock Australia confirmed on Monday.Twenty people have fallen ill in Japan's Toyama prefecture, with 15 of them infected with the O157 strain of E.coli after eating at a popular Korean-style barbecue restaurant chain, Gyukaka, on May 6.The operators of the restaurant chain, REINS International, said they suspected the bacterium might have been carried by beef imported from Australia.After conducting an investigation into the Japanese outbreak, regional manager for Meat and Livestock Australia, Melanie Brock, said testing shows Australian beef was not the source of the outbreak."The Toyama prefecture health authorities have confirmed following a thorough inspection that imported Australian beef was not the source of an incident of E.coli," Brock said in a statement on Monday."The authorities continue to investigate other food consumed by the affected customers."Brock said Australian beef has long been recognized by the Japanese trade and consumers for its strong safety record.Brock added that Australian beef for export to Japan is processed under the veterinary supervision of the Australian Quarantine and Inspection Service, and is recognized internationally as bearing a high hygienic standard.

LOS ANGELES, June 29 (Xinhua) -- The war on cloud intensified as Microsoft Office announced its decision on Tuesday to go cloud in an attempt to compete with its immediate but not last competitor, Google Docs.Microsoft holds a virtual monopoly on office productivity software. Most computer users in the world use the Office software for word processing, spreadsheet, presentation and other purposes. However, Microsoft Office faces a strong enemy -- Google Docs, which provides cloud service, that means users do not have to purchase any software to be installed on their computers. If they go online, they can start use the application, and they do not need to worry about their files, because the files also go with the cloud, and users can get access to their files at anytime, anywhere.The cloud-based Office 365 is designed for the mobile age when people go with their software and documents.The actual features and functionality of the tools have a lot of bearing on which productivity suite users choose. The Word Web App is more visually appealing and polished than its Google counterpart, but overall the two seem roughly equivalent in features.When tested on a sample presentation in both the PowerPoint Web App and Google Docs Presentation, the PowerPoint Web App immediately presented with a diverse selection of attractive themes to choose from, but Google defaulted to plain black text on a plain white background.On slide and image, in Google Presentations, the image filled the whole slide but the PowerPoint Web App was smart enough to size the image automatically.When push comes to shove, the features of the Office Web Apps in Office 365 are pretty much the same as what Google Docs has to offer. However, Microsoft makes key features easier to get to, and works more intuitively. For users already familiar with Microsoft Office, the Office Web Apps version is easy to use.Both Office 365 and Google Docs are Web-based platforms, and they will work from any Web browser. Google Docs excels in the Chrome browser while Microsoft Office 365 works best in Internet Explorer. It makes sense that each would make sure that their online productivity tools are optimized for performance and functionality in their own browser.Collaboration in real time is the primary selling point of Google Docs, which can be shared with any other Google account. The users who share a file can all access and work with it simultaneously. Each user is assigned a unique color so users can easily identify who is making changes to what.But in the price war, Microsoft can not beat Google Docs. Office 365 starts at six dollars per user per month for the Professional and Small Business plan. The Medium Business and Enterprise plans range from 10 to 27 dollars per user per month. But the Google Docs is free.Microsoft also faces a challenge on how to go cloud while still keep the computer-based Office software.Statistics showed that nearly nine of every 10 office computers runs one of the 14 versions of Office the company has released since the software's launch in 1989. The company now needs to convince those computer users, estimated at about one billion, to switch to Office in the cloud without disrupting the legacy version that is financing the transition.The growing cloud market is profitable. The International Data Corp. projected the market for cloud-computing services and software is expected to grow more than 27 percent annually over the next five years and reach 73 billion dollars by 2015.It is estimated that by 2015 one of every seven dollars spent on technology will be connected with cloud computing and the winners of the cloud platform wars will likely be the new power brokers of the IT industry.It is reported that Salesforce.com has added a communication technology called Chatter to its service to allow clients to communicate within its sales management cloud service. Amazon's Elastic Cloud has attracted enterprise customers because of its ability to scale up capacity to match peaks in client demand.By 2015, it is estimated that software-oriented cloud services will account for roughly three-quarters of all spending on public cloud services.

WELLINGTON, July 29 (Xinhua) -- Scientists from around the world will gather on the east coast of New Zealand next week to discuss proposals to study "silent" earthquakes by drilling into the seabed.Silent quakes, also known as slow slip events, occur on the boundaries of the earth's tectonic plates, where one plate dives under another in areas known as subduction zones, and are slower than normal quakes, taking weeks or months to occur rather than seconds, and are rarely felt on the surface.About 70 scientists from 10 countries will convene in the city of Gisborne, which lies near the site of a major fault line and where scientists first identified silent earthquakes in 2002.Slow-slip events were first discovered with the advent of new measurement technologies on the west coast of Canada about 15 years ago and have since been recorded at about a dozen locations around the world, including four sites around New Zealand, said a spokesperson for New Zealand's Institute of Geological and Nuclear Sciences (GNS Science).About eight slow-slip episodes have occurred under Gisborne since 2002 at roughly two-year intervals.Scientists have proposed numerous theories to explain the phenomenon, but testing the theories is difficult as silent quakes happen many kilometers below ground."The best way to understand the true cause of slow-slip events is to drill into and sample the area on the plate boundary fault where they are known to occur, and monitor a whole range of physical and chemical properties at the plate interface," said Laura Wallace, of GNS Science.

WASHINGTON, July 18 (Xinhua) -- The U.S. National Aeronautics and Space Administration (NASA) on Monday commemorated the 90th birthday of astronaut John Glenn, the first U.S. astronaut to orbit the Earth and also the oldest person to fly to space when he launched on the space shuttle in 1998."John Glenn is a legend, and NASA sends him our best wishes on this major personal milestone," NASA Administrator Charles Bolden said in a statement. "John's legacy and contributions to the continued progress of human spaceflight are immense. His example is one we continue to emulate as we push toward farther destinations in the solar system."After a distinguished flying career with the Marines in World War II and Korea, Glenn joined NASA in 1959 as one of the country' s first astronauts in Project Mercury. On Feb. 20, 1962, Glenn piloted the Mercury-Atlas 6 "Friendship 7" spacecraft on the first U.S. manned orbital mission. He launched from NASA's Kennedy Space Center in Florida to successfully complete three orbits of the Earth.Glenn flew to space again on the STS-95 mission in 1998 aboard the space shuttle Discovery. As a mission specialist, Glenn supported deployment of a variety of research payloads and participated in investigations about spaceflight and the aging process.
