SAN FRANCISCO, June 28 (Xinhua) -- Microsoft on Tuesday launched its cloud service Office 365, which was the software giant's answer to competing products from Google and other companies.The service includes on-line versions of Word, PowerPoint, Excel, Outlook and other Office applications, as well as Microsoft 's communication and collaboration tools such as Exchange, SharePoint and Lync.It will allow users to work on files and documents at the same time using instant messaging and video-conferencing."Where does Office meet the cloud? It's Office 365, the absolute best productivity and collaboration service for business around the world," Microsoft CEO Steve Ballmer said at a webcast event.Microsoft said that Office 365 is now available in 40 markets with choices for small and big businesses ranging from 2 to 27 U.S. dollars per user per month.Office 365 will compete directly with the web-based Google Apps, which Google sells for 50 dollars per user per year.Microsoft's service was introduced in beta last year and the company said response was enthusiastic with more than 200,000 organizations signed up and began testing it in a few months."With a few clicks, Office 365 levels the playing field, giving small and midsize businesses powerful collaboration tools that have given big businesses an edge for years," Ballmer said in a statement.

BEIJING, July 5 (Xinhuanet) -- Facebook CEO Mark Zuckerberg confirmed that he has signed up to Google+, the new social networking platform from Google, according to media reports Tuesday.Launched last month, Google+ is the Internet giant's latest foray into social networking.Zuckerberg confirmed that the profile with his name on Google+ belongs to him only, and said, "Why are people so surprised that I'd have a Google account?" Facebook CEO Mark Zuckerberg reacts after unveiling a new messaging system during a news conference in San Francisco, California November 15, 2010.In social networking field, it is rare for someone to join the rival's platform, therefore, Zuckerberg's move is considered strange.But interestingly, Zuckerberg has more followers than Google founders Larry Page and Sergey Brin, and even Vic Gundotra, the man behind Google+, with over 21,000 people.Besides Google+, Zuckerberg also has an account on Twitter, though it has not been updated for some time.

LOS ANGELES, July 6 (Xinhua) -- NASA scientists have got the first-ever, up-close details of a Saturn storm that is eight times the surface area of Earth, the Jet Propulsion Laboratory ( JPL) announced on Wednesday.The images were captured by NASA's Cassini spacecraf, according to JPL in Pasadena, Los Angeles.On Dec. 5, 2010, Cassini first detected the storm that has been raging ever since. It appears approximately 35 degrees north latitude of Saturn.The storm is the biggest observed by spacecraft orbiting or flying by Saturn. NASA's Hubble Space Telescope captured images in 1990 of an equally large storm.Pictures from Cassini's imaging cameras show the storm wrapping around the entire planet covering approximately two billion square miles (4 billion square kilometers).The storm is about 500 times larger than the biggest storm previously seen by Cassini during several months from 2009 to 2010. At its most intense, the storm generated more than 10 lightning flashes per second.Cassini has detected 10 lightning storms on Saturn since the spacecraft entered the planet's orbit.Those storms rolled through an area in the southern hemisphere dubbed "Storm Alley." "Cassini shows us that Saturn is bipolar," said Andrew Ingersoll, a Cassini imaging team member at the California Institute of Technology in Pasadena, California. "Saturn is not like Earth and Jupiter, where storms are fairly frequent. Weather on Saturn appears to hum along placidly for years and then erupt violently. I'm excited we saw weather so spectacular on our watch."The new details about this storm complement atmospheric disturbances described recently by scientists using Cassini's composite infrared spectrometer and the European Southern Observatory's Very Large Telescope. The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. NASA's JPL manages the mission for the agency's Science Mission Directorate in Washington.

PARIS, June 19 (Xinhua) -- Commercial Aircraft Corporation of China Ltd. (Comac) on Sunday set up its European office in Paris, the second overseas branch after its U.S. office, marking a new step for China's aviation industry in opening-up and international exchanges."The establishment of Comac Europe office is very significant. It represents the strategic cooperation between China and France and will deepen the two sides' collaboration in aerospace and all areas concerned," Chinese Ambassador Kong Quan said at an opening ceremony, citing Europe's influence in global aerospace industry and civil aviation market."Taking self-dependent innovation as the strategic cornerstone, Comac meanwhile actively conducts international cooperation and draws upon advanced technologies and experience in global civil aviation industry...," Comac President Jin Zhuanglong said.French Secretary of State for Transport Thierry Mariani (4th L), Chinese Ambassador to France Kong Quan (3rd L) and General Manager of the Commercial Aircraft Corporation of China (COMAC) Jin Zhuanglong (2nd R) attend the unveiling ceremony of COMAC Europe Office in Paris, France, June 19, 2011. The COMAC Europe Office was offically opened here Sunday.The Chinese aerospace manufacturer has built up cooperative relationship and partnership with dozens of enterprises and institutions in many countries and regions since its establishment in May 2008 in Shanghai.Regional jet ARJ21 and the trunkliner C919 are two flagship products of the young Chinese company. The group is now working to achieve certification and delivery of ARJ21-700 aircraft by the end of this year, Jin said.With regard to China's C919 trunkliner program, Jin said COMAC has signed cooperation agreements with 17 international companies in the United States and Europe, and has actively explored collaboration with GECAS, British Airways and Ryanair."In the context that the world economy is on recovery from the financial crisis, the civil aviation industry is facing great challenge. We are willing to keep close contact with all relevant public administrations and forge friendly relations and cooperation with overseas suppliers to contribute to the development of world civil aviation industry," Jin said.For the French State Secretary for Transport Thierry Marianne, who also attended the opening ceremony, the Chinese aviation market has great potential in the years to come, and China is estimated to need 3,000 new planes."We have understood that China had decided to build its own aerospace industry. It is a legitimate choice," Marianne said.A demo mock-up of the full-scale forward fuselage of C919 will be displayed during the 49th Paris Air Show on June 20-26, which will be the first time that the 1:1 demo mock-up is to be showcased at an international stage outside China, Jin told Xinhua.During the air show, Comac is going to sign agreements with an international airline and an airborne-system supplier and carry out a series of activities concerning international cooperation and exchanges, according to the group.
