VIENNA, Aug. 11 (Xinhua) -- Austrian researchers have developed a method of using fungi and produced enzymes to split Polyethylene Terephthalate (PET) material into their initial state, enabling the recovery of all individual components, said the Austrian Center of Industrial Biotechnology (ACIB) Thursday in a press release.Enzyme is a special protein that acts as biological catalyst, for example, bacteria and fungi in the nature can break down long chain molecules.Researchers from the Technical University of Graz, the Technical University of Vienna and the Agricultural University of Vienna jointly found that efficient enzymes are capable to break and split PET into small fragments.With different methods, the researchers forced the fungi to overproduce their precious "split-tools" after they are modified and improved by genetic engineering.Through the new method developed by the ACIB, it is now possible to decompose the PET polymer to its initial monomers with high product quality and from this to produce new high-quality materials again.This circuit avoids waste and thus saves resources and is friendly to the environment, said Geog Guebitz, head of the Research Department on Enzymes and Polymers in the ACIB.He further explained that the ACIB has established a partnership with some industrial enterprises to carry out application experiments. From the current splitting time of 24 hours, the researchers expect to shorten the whole process to "a few hours," he added.PET is a common plastic material in the polyester family, widely used in the textile industry. PET film is mainly used in electrical insulation materials, which can be also used for production of film, X-ray films and computer taps, even to produce plastic bottle and other blow molding products.

WASHINGTON, July 10 (Xinhua) -- U.S. space shuttle Atlantis docked with the International Space Station on Sunday morning after nearly two days of flight.Commander Christopher Ferguson guided space shuttle Atlantis to a docking with the station at 11:07 a.m. EDT (1507 GMT) when the two spacecrafts were flying 240 miles up over east of New Zealand, according to NASA.This was the 12th and final time Atlantis docked to the space station. It was the 46th shuttle docking to a space station, nine to the Russian Mir station and 37 to the International Space Station.The space shuttle Atlantis is seen with part of the structure of the International Space Station in the foreground and the earth in the background as it approaches the station for docking in this still image from NASA TV July 10, 2011. The shuttle and station crews will open hatches and hold the traditional welcome ceremony at about 1:19 p.m. EDT (1719 GMT). The combined crew of 10 will begin more than a week of docked operations, transferring vital supplies and equipment to sustain station operations once the shuttles are retired.Atlantis lifted off on Friday morning from Kennedy Space Center in Florida, on the 135th and final flight in NASA's shuttle program.It is the 33rd voyage for Atlantis. Its return to the earth later this month will mark the end of the 30-year shuttle program.

SAN FRANCISCO, July 12 (Xinhua) -- Google+, the social networking service Google unveiled only two weeks ago, is estimated to surpass 10 million users on Tuesday, possibly becoming the fastest growing product in the history of the Internet.According to Ancestry.com founder Paul Allen (not the co- founder of Microsoft), after passing 10 million users, Google+ " could reach 20 million users by this coming weekend if they keep the Invite Button available."Allen looks for last names on Google+ and compares them with U. S. Census Bureau data on the popularity of surnames to statistically project the number of Google+ users."Since I have been tracking this same cohort of surnames from my first day, I am able to accurately measure growth over time," he said in a blog post on Google+ website.Google so far has not released any details about the Google+ users or the number of users. Speaking at a press event last Thursday in Sun Valley in the U.S. state of Idaho, former Google CEO and current Executive Chairman Eric Schmidt said there are " millions" of users.Industry watchers think the estimate may not be completely accurate, but Allen should be capturing the growth trajectory of Google+, which shows that a social network could undergo an exponential growth in its early days.

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.
