London, Feb 27 : In response to the furore over Facebook''s revision of user Terms of Service (TOS), the company''s founder Mark Zuckerberg has announced that the member of the social networking site will now have comment and voting rights over its future policies.

The social-networking giant came under fire after Consumer advocacy blog The Consumerist reported that the revised policy allowed the website to hold a perpetual license to use its members'''' uploaded content to promote itself, even after their accounts had been deleted.

Washington, Feb 26 : In a previously untested method, solar power cells have been produced by printing presses normally used to make Australian dollar bills.

According to a report in National Geographic News, the giant machines arranged and stamped flexible solar panels onto plastic film, in a trial near Melbourne last week.

The cells were only 3 percent efficient, meaning they could convert only a small amount of solar energy into electricity.

But, Commonwealth Scientific and Industrial Research Organisation (CSIRO) project leader Gerry Wilson told Australian ABC News that he expects the output to more than double by next year and top 10 percent after that.

Washington, Feb 26 : Using data from the satellite-based MIPAS and GOME-2 instruments, scientists have for the first time detected important ozone-depleting species in the atmosphere.

These new measurements will help scientists to better understand sources of these bromine species and to improve simulations of stratospheric ozone chemistry.

Despite the detection of bromine monoxide (BrO) in the atmosphere some 20 years ago, bromine nitrate (BrONO2) was first observed in 2008 when scientists from the Karlsruhe Institute of Technology discovered the gas's weak signal with data from MIPAS (the Michelson Interferometer for Passive Atmospheric Sounding).

London, Feb 26 : A new research by a team led by the University of Nottingham, UK, has identified interstellar space dust from a dead star, which could unlock some of the mysteries of the early universe.

Interstellar dust is found throughout the cosmos. It is responsible for the dark patches seen in the Milky Way on a moonless night.

It consists of carbon and silicate particles, about the size of those in cigarette smoke.

Washington, Feb 26 : A new study has indicated that small robots the size of riding mowers could prepare a safe landing site for NASA's Moon outpost in the future.

The study, by Astrobotic Technology and Carnegie Mellon researchers, analyzed mission requirements and developed the design for an innovative new type of small lunar robot under contract from NASA's Lunar Surface Systems group.

The pace of adoption of open source software (OSS) among micro, small and medium enterprises (MSMEs) has not gained traction, despite the slowdown and IT costs hitting a downside. “We have about 8,000 MSME members in the Confederation of Indian Industry’s (CII) MSME division and hardly, any of them use the OSS. CII has planned a host of initiatives to promote OSS considering that it can improve productivity considerably,” said a CII official at a seminar on open source software and MSMEs organised by CII on Wednesday.
