Washington, August 22 : A Virginia Tech researcher has discovered a way to grow omega-3 fatty acids, known for their potential human health benefits, by using a byproduct of the emerging biodiesel industry.

Zhiyou Wen, assistant professor of biological systems engineering in Virginia Tech''s College of Agriculture and Life Sciences, presented his findings at the 236th national meeting of the American Chemical Society (ACS) in Philadelphia on Thursday.

London, Aug 22 : You can now stop worrying about the way you look while sitting, for iPosture – a small gadget which can be stuck on the skin and buzzes to remind the wearer to sit up straight, helping improve posture – has come to your rescue.

The revolutionary device vibrates discretely when the wearer slouches by more than three degrees for one minute.

Once the posture is corrected the buzzing stops and users have been found to adopt better habits after wearing the device for four hours a day for up to a month.

It comes after researchers proved that the Alexander Technique - a method of teaching better bodily alignment, posture and balance - helps reduce back ache.

London, August 22 : A new computer simulation has suggested that stars can form in the hostile environment around a black hole after all.

The area around a black hole was thought to be too violent to form stars, since intense gravitational forces there could rip apart gas clouds in which stars are born.

But, according to a report in New Scientist, a new computer simulation shows a gas cloud on a near-collision course with a black hole could survive these forces.

New Delhi - Indian telecommunications majors Bharti Airtel Ltd and Vodafone Group PLC launched the third-generation Apple iPhone Friday across India, the world's fastest growing mobile phone market.

At 30,000 rupees (690 dollars), the iPhone 3G costs almost triple its price in the United States, where it is subsidized by telecommunications operator AT&T Inc in its effort to win customers' annual subscription fees.

The Apple iPhone, launched by Vodafone and Bharti Airtel on Thursday, was welcomed with such a boom that users waited in lines outside a Gurgaon mall and few shops in Delhi to get their very own iPhone.

Among the enthusiast fans, Swati, a college student was one of the first to get her iPhone. She got there as early as 7pm and waited in queue at the Sahara Mall, and finally, she was handed over the phone by president of Bharti, Sanjay Kapoor.

Washington, Aug 22 : Researchers at the University of Washington have developed a software that enables deaf and hard-of-hearing individuals to use sign language – over a mobile phone.

UW engineers got the phones working together this spring, and recently received a National Science Foundation grant for a 20-person field project that will begin next year in Seattle.

This is the first time two-way real-time video communication has been demonstrated over cell phones in the United States. Since posting a video of the working prototype on YouTube, deaf people around the country have been writing on a daily basis.
