London, Dec 30 (ANI): Get ready for a mobile video phone that can be worn on the wrist just like a watch, all thanks to a South Korean technology firm that has unveiled the world's first "3G watch phone."

The unique phone by LG Electronics boasts a touch-screen dialling system with a camera and an in-built speaker.

With all these features, the users could make video calls and gain high-speed Internet access.

The device also recognises voices, transforms text to speech, has a Bluetooth function and also works as an MP3 player.

The high-end handset is due to be launched in Europe later next year, reports The Telegraph.

With a 1.43-inch (3.63-centimetre) screen, the product is 0.56 inches (13.9 millimetres) in thickness.

The 3G watch phone will go on display at the 2009 Consumer Electronics Show (CES) in Las Vegas from Jan 8 to 11.

The device makes part of a trend towards multi-tasking gadgets that can perform a host of functions. (ANI)

TUESDAY, December 30, (News Locale) - The quest to get to the bottom of what actually causes disease process in humans is to unlock the mysteries hidden in stem cells. But thus far scientists had been unable to isolate stem cells in rats, which could enable them to genetically engineer the animals to mimic human disease models.

London, Dec 9 (ANI): A new research has suggested that meteorite impacts during Earth's early history could have created amino acids, which kick-started life on the planet.

Exactly how and when organic molecules appeared in abundance on the young Earth, leading to the origin of life about 4 billion years ago, has been unclear.

But, according to a report in New Scientist, a new research by Yoshihiro Furukawa at Tohoku University in Sendai, Japan, and colleagues, suggests that meteor impacts could have created amino acids, the building blocks of life.

The team used a high-velocity propellant gun to simulate the impacts of ordinary carbon-containing chondrite meteorites, the most common type of meteorite, into the early ocean.

Afterwards, they recovered a variety of organic molecules, including fatty acids, amines, and an amino acid.

Oceans began to form about 4.3 billion years ago, when meteorites were hitting Earth about 1000 times more frequently than they do today, according to Furukawa.

"This study is the first to show that an amino acid can be synthesised by a naturally possible mechanism on the early Earth," he said.

Although the team generated only one type of amino acid, they suspect that by varying the conditions of their experimental impacts, they will be able to generate others.

In earlier meteorite impact studies, the team generated fine particles, which they say had the potential to become clay.

According to the researchers, during an impact, clay could have trapped substantial amounts of the organic molecules formed in the same event, and then settled as marine sediment.

Some of these organic molecules might have evolved as a precursor to life. The rest might have sunk to the deep crust and mantle to become graphite or diamond. (ANI)

Washington, Dec 9 (ANI): You must have seen people getting enraged and taking up the biggest of fights after the most trivial of things without any reason after all. But now, University of Minnesota researcher Vladas Griskevicius has found out what leads people to make a mountain out of a molehill- aggression, status and sex. While hostility or belligerent acts might not immediately appear to be linked to reproduction, the new study has shown that mating goals may be behind aggressive behaviours among people.

Griskevicius, a marketing professor at the U of M's Carlson School of Management, and his colleagues have found conclusive evidence that merely activating a desire for status can trigger aggression.

Aggressive displays, which may result in enhanced status, indirectly boost an individual's ability to attract a mate and, thereby, reproduce.

"It all boils down to the fact that status for men typically equals sex. Across different cultures and time, the higher status men have, the more sex or better-quality partners they may have. At the gene-level, nobody wants to go down in an evolutionary blaze of glory--no one wants their genes to become extinct. Additionally, unlike low-status women, low-status men are in serious danger of not reproducing, since they make especially undesirable mates," said Griskevicius.

He added: "Think of it this way. For men, fighting for status is akin to fighting for the survival of their genes. Not caring about status, which can be implied by backing away from a fight, can be evolutionary suicide. Aggression can lead to status. A higher status leads to sex, and that leads to more or higher-quality offspring."

Scientists displayed the evolved pull of aggression in a series of three studies.

The results showed that if men have status or sex on their minds (e.g., they are thinking about a promotion at work or an attractive opposite-sex individual), they would more quickly respond aggressively to a trivial insult.

The slight seems much more substantial when a man has sex or status on his mind. Men are especially likely to respond aggressively when there are other men around to watch the situation, suggesting that much of aggression is about display, rather than self-defence.

And the idea is supported by statistics, for police reports show that "trivial altercations" is the leading reason for homicide.

However, Griskevicius has warned that his work should not suggest that people are attracted to aggression.

Rather, "it is all about status--the one who wins the game--he's the one that gets the girl. And at the end of the day, if those genes are passed on, the aggressor is the ultimate winner," he said.

The study has been published in the forthcoming issue of the Journal of Personality and Social Psychology. (ANI)
