Bangalore, Oct 10 : Chandrayaan I, India ''s spacecraft mission to moon will be launched on October 22 from the Satish Dhawan Space Centre in Sriharikotta.

The spacecraft has been fully integrated with all instruments and is presently under going final stages of tests at the launch complex.

ISRO Chairman Mr Madhavan Nair said the mating of the spacecraft with the launch vehicle and the satellite would take place on October 17.

London, October 10 : Google Earth’s new satellite, GeoEye-1, has provided a high resolution picture of Pennsylvania-based Kutztown University campus, which also happens to be its first picture.

The satellite took the picture on Tuesday when it was in a 423-mile-high orbit over the East Coast of the U. S.

"We expect the quality of the imagery to be even better as we continue the calibration activity," the Telegraph quoted Brad Peterson, GeoEye''s vice president of operations, as saying.

Washington, Oct 10 : A Northwestern University-led research team has identified a promising new material that could efficiently convert waste heat into electricity to help power cars and improve gas mileage.

The researchers discovered that adding two metals, antimony and lead, to the well-known semiconductor lead-telluride, produces a thermoelectric material that is more efficient at high temperatures than existing materials.

"We cannot explain this 100 percent, but it gives us a new mechanism - and probably new science - to focus on as we try to raise the efficiency of thermoelectrics," said Mercouri G. Kanatzidis, Charles E. and Emma H. Morrison Professor of Chemistry in the Weinberg College of Arts and Sciences.

London, Oct 10 : Data security worries could soon be an anxiety of the past, courtesy the world''s first computer network protected by unbreakable quantum encryption.

The EU-sponsored project (called SECO-QC) has been successfully demonstrated at a scientific conference in Vienna.

The network connects six locations across Vienna and in the nearby town of St Poelten, using 200 km of standard commercial fibre optic cables.

The kinds of security schemes used on computer networks today are typically based on complex mathematical procedures, which are extremely hard for outsiders to crack, but not impossible given sufficient computing resources or time.

Washington, October 10 : A pair of Penn State researchers has come up with a statistical approach that may one day make Internet searches for photographs quite easier.

The tool they use for this purpose is called Automatic Linguistic Indexing of Pictures in Real-Time (ALIPR), which works by teaching computers to recognize the contents of photographs, such as buildings, people, or landscapes.

The procedure is very different from searching for keywords in the surrounding text, as is done with most current image-retrieval systems.

The team recently received a patent for an earlier version of the approach called ALIP, and is in the process of obtaining another patent for the more sophisticated ALIPR.

New York - In a rare piece of positive economic news, IBM shares jumped as much as 4.9 per cent Thursday morning after the company reported that its third-quarter earnings rose 22 per cent to 3.9 billion dollars.

Shares in the technology powerhouse gave back some of the gains as analysts focused on-less-than expected growth in revenue, which inched up 2 per cent to 25.3 billion dollars, falling short of the 26.53 billion dollars expected by analysts.
