Spotted: A black hole that survived galaxy destruction

WASHINGTON: Astronomers have spotted a rare mid-weight black hole some 290 million light-years from Earth which they say offers clues about a now-destroyed galaxy that may once have existed around it. 

Researchers at the Sydney Institute for Astronomy in Australia who spotted the black hole using the Hubble Space Telescope think the dwarf galaxy was torn apart by the gravity of a larger host galaxy that it orbited. 

The violent encounter they would have stripped away most of the dwarf galaxy's stars, but it
also could have compressed the gas around its central black hole, triggering a new wave of star formation, LiveScience reported.

Cell ringtone a distraction while working

LONDON: It's always better to keep your cell phone on silent mode particularly when you are trying to solve a problem, for a study says thatmobile ringtones can distract you - especially if it's your favourite song. 

Researchers at Washington University in St Louis have claimed that mobile phone ringtones affect concentration most when they are popular songs - in fact, they can brain power, the Daily Mail reported. 

"Many of us consider a mobile phone ringing in a

Japan scientist makes 'Avatar' robot

YOKOHAMA: A Japanese-developed robot that mimics the movements of its human controller is bringing the Hollywood blockbuster "Avatar" one step closer to reality.

Users of the TELESAR V don special equipment that allows them not only to direct the actions of a remote machine, but also to see, hear and feel the same things as their doppelganger android.

"When I put on the devices and move my body, I see my hands having turned into the robot hands. When I move my head, I get a different view from the one I had before," said researcher Sho Kamuro.

"It's a strange experience that makes you wonder if you've really become a robot," he told AFP.

Professor Susumu Tachi, who specialises in engineering and virtual reality at Keio University's Graduate School of Media Design, said systems attached to the operator's headgear, vest and gloves send detailed instructions to the robot, which then mimics the user's every move.

Your own stem cells can repair damaged heart

LONDON: Scientists have found that infusion of heart's own stem cells can repair the damage caused to the organ following an attack , a find they say could lead to new treatment strategy for cardiac regeneration.

The study, published in the Lancet, showed that the cells help the organ re-grow healthy muscle after a heart attack, challenging the belief that cardiac scarring is permanent and that once lost, healthy heart muscle cannot be restored.

In the research, a team led by Eduardo Marban at the Cedars-Sinai Heart Institute in Los Angelesassessed a group of 25 patients, with an average age of

Seven hours of sleep a day enough for teens: Study

LONDON: Want to do well at school? Then, cut down on your lie-ins, as teenagers do not need more than seven hours of sleep a day, scientists say.

A team at the Brigham Young University in Utahfound that teenagers performed better academically if they had more regular sleep patterns limited to just seven hours.

It's believed that a typical 16-year-old needs nine hours of sleep a night, but the optimum amount is just seven hours, said lead study author Eric Eide.

"We are not talking about sleep deprivation. The data simply says that

A PC that thinks like a man, has an IQ of 150!

LONDON: Scientists have created a 'genius' computer, using a mix of logic and 'humanlike' thinking, that they claim can score 150 in an IQtest. A team in Sweden says the computer actually works on a programme which uses a mixture of mathematical logic and 'human-like' thinking, enabling it to outperform previous software on IQ tests, the Daily Mail reported.

Even advanced maths programmes usually score below 100. "We're trying to make programmes that can discover the same types of patterns that humans can see," said team leader Claes Strannegard at University of
