London, Oct 26 : British scientists have developed purple-coloured tomatoes that may protect against cancer.

The research team from John Innes Centre has created tomatoes genetically modified to produce antioxidants that may help keep cancer at bay.

The plant was created by introducing the genes from the snapdragon, a garden flower that allows them to produce a type of nutrient that prevents cancer.

When these tomatoes were fed to mice genetically engineered to have cancer the animals'' lifespans were significantly extended.

The researchers hope that the "super-tomato" could help people meet the government''s recommendation that everyone should eat five portions of fruit and vegetables a day.

London, Oct 26 : State-of-the-art computer graphic systems developed for movies and games have made it possible to model in unprecedented detail the swirling rings and tubes that are a characteristic of turbulent vortices.

According to a report in New Scientist, the models will help explain the forces that govern vortex decay.

This could lead to ways to control them in places where they cause problems, such as over aircraft wings or in blood vessels.

Computer graphics technology for games and movies has progressed to the point that it can render photoreal simulations of flowing liquids.

London, October 26 : A new study conducted by researcher at the University of Florida suggests that wolves, not dogs, are the clever ones.

Study leader Monique Udell and her colleagues worked with a mixture of pet dogs, dogs from animal shelters that had had minimal interaction with people, and wolves raised by humans.

The researchers exposed their animals to an experiment in which they were shown two upside-down cups, one of which covered food. A human would then gesture in some way at the cup covering the food.

The experiment was conducted with the presumption that if the animal being tested was properly interpreting the gestures, it should have been lured to the object that the experimenter was indicating.

London- Champions Manchester United slipped up in their pursuit of Chelsea and Liverpool at the top of the English Premier League on Saturday when they were held to a 1-1 draw at Everton.

Darren Fletcher put United in front on 22 minutes but Marouane Fellaini headed the equalizer for Everton with just under half an hour to go to give the home side a share of the spoils.

The point means United remain fifth, still five points behind Chelsea and Liverpool, who play each other at Stamford Bridge on Sunday.

London, Oct 25 : Flavio Briatore is now ready to put his money on Lewis Hamilton to win this year’s Formula One title - just a week after writing off his chances.

The Renault boss played down Hamilton’s chances ahead of last week’s Chinese Grand Prix, but the McLaren ace stormed to victory to leave himself on the brink of becoming F1’s youngest world champion.

Briatore claimed the fact that Hamilton let a 17-pointlead slip away last season with two races remaining was “worthy of the Guinness Book of Records.”

London, Oct 25 : A Brit couple has a collection of 4000 clocks and is turning them back as the British summertime ends.

The task will take Pauline West and her husband Roy at least two days as they unwind a collection covering pretty much every nook and corner of their two-bedroom flat.

“It’s a big job — all the clocks have to tell exactly the same time. But I’ve had plenty of practice and I’m a lot quicker than I used to be,” The Sun quoted West, as saying.

West, 57, and Roy, 64, who have been picking up clocks since ages and began buying them for a mere 50p, have run out of place to accommodate the clocks.
