A small planet just seven or eight times as massive as the Earth has been found circling a nearby star. Astronomers say it is the most Earth-like world we have ever seen beyond our solar system.
"For the first time, we are beginning to find our planetary kin among the stars," says Geoff Marcy of the University of California at Berkeley, US. His team announced the discovery at a news conference in Arlington, Virginia, US, on Monday.

An extract from a plant known in the US as "the vine that ate the South" may help reduce alcohol consumption in heavy drinkers, a small-scale study suggests.
Brian Roberts first tried on his newfangled contact lenses about an hour before the Orioles' last spring training game in Florida. He ripped three hits on a day his teammates groused about the difficulties of seeing the ball in the bright sun shining from a cloudless sky.
A new class of drug may increase alertness without any of the jitteriness of over-stimulation, suggest the results of a small clinical trial released this week.
A compound dubbed CX717, a member of the new class called ampakines, significantly improved performance on tests of memory, attention, alertness, reaction time and problem solving in healthy men deprived of sleep.
The study was carried out by Julia Boyle at the Sleep Research Centre at the University of Surrey, UK, and her colleagues on behalf of Cortex Pharmaceuticals Inc., based in Irvine, California, US.
Twenty-three years ago, an American philosophy professor named James Flynn discovered a remarkable trend: Average IQ scores in every industrialized country on the planet had been increasing steadily for decades. Despite concerns about the dumbing-down of society - the failing schools, the garbage on TV, the decline of reading - the overall population was getting smarter. And the climb has continued, with more recent studies showing that the rate of IQ increase is accelerating.
