WASHINGTON, Sept. 15 (Xinhua) -- A team of researchers has discovered a planet that orbits around a pair of stars, the U.S. space agency NASA announced Thursday.This is the first instance of astronomers finding direct evidence of a so-called circumbinary planet. A few other planets have been suspected of orbiting around both members of a dual-star system, but the transits of the circumbinary planet have never been detected previously.The team, led by Laurance Doyle of the SETI Institute in California, used photometric data from the NASA Kepler space telescope, which monitors the brightness of 155,000 stars.NASA's Kepler mission has discovered a world where two suns set over the horizon instead of just one. The planet, called Kepler-16b, is the most "Tatooine-like" planet yet found in our galaxy. Tatooine is the name of Luke Skywalker's home world in the science fiction movie Star Wars. In this case, the planet it not thought to be habitable. It is a cold world, with a gaseous surface, but like Tatooine, it circles two stars.They found the binary star system by detecting a system where the stars eclipsed each other from the perspective of the Kepler spacecraft. These stars have two eclipses: A primary eclipse when the larger star is partially blocked by the smaller star and a secondary eclipse where the smaller star is fully blocked by the larger star.But the researchers also noticed other times when the brightness of the two stars dropped, even when they were not in an eclipse position. This pattern suggested that there was likely a third object involved. The fact that these so-called tertiary and quaternary eclipses recurred after varying intervals of time, and were of different depths, indicated that the stars were in different positions in their orbit at each instance. This result showed that the tertiary and quaternary eclipses were being caused by something circling both stars, and not an object circling one or the other star.Measurements of the variations in the timing of all four types of eclipses, resulting from the mutual gravitational interactions of the two stars and the third body, demonstrated that the third object was, indeed, a planet. Their work indicates that the planet is less massive than Jupiter, possibly comparable in mass to Saturn, and that the larger of the two binary stars is smaller than our Sun.Their findings will be published Friday in Science."This discovery confirms a new class of planetary systems that could harbor life," Kepler principal investigator William Borucki said in a statement. "Given that most stars in our galaxy are part of a binary system, this means the opportunities for life are much broader than if planets form only around single stars. This milestone discovery confirms a theory that scientists have had for decades but could not prove until now."

BEIJING, Sep. 1 (Xinhuanet) -- Apple lost another iPhone prototype at a Bay Area bar, according to media reports Thursday.It is reported that an Apple employee lost a prototype iPhone at San Francisco bar Cava 22 in late July, which is a tequila bar in the mission district.A joint investigation by Apple and San Francisco police searched a local house but could not find it, the reports added.It seems that Apple employees learned nothing from last year’s lost iPhone scandal. A prototype iPhone 4 was lost in a Redwood City bar last year.Apple has denied any knowledge of the incident, and San Francisco police stated that Apple did not file a police report for the lost merchandise.If the reports are true, it would be a big blow to Apple’s ego since the company takes pride in its secretive nature.

SAN FRANCISCO, Aug. 22 (Xinhua) -- Hewlett-Packard (HP) on Monday unveiled a new business desktop computer, days after the world's largest personal computer (PC) maker announced its plan to sell its PC business.The company said the new model, HP Compaq 8200 Elite All-in-One Business Desktop, is the industry's first all-in-one PC that integrates Intel's second-generation Core vPro technology, which can deliver up to 40 percent better performance, 15 percent faster hard drive access and reduced downtime via remote information technology management."Another industry first in our Elite desktop family demonstrates our commitment to engineering excellence and underscores our global leadership in secure, enterprise computing, " Jeff Groudan, HP's director of commercial desktop marketing, said in a statement.HP said the new computer is available now in the United States. It starts at the price of 999 U.S. dollars, and comes with a standard three-year warranty.Last Thursday the company announced that it is considering a full or partial separation of its PC business through a spin-off or other transactions, a process that HP estimates may take about 12 to 18 months.

BEIJING, Aug. 11 (Xinhuanet) -- Next year will bring a doubling in the size of the words that appear on cigarette packages to warn consumers of the dangers of smoking. Starting in April 2012, cigarettes produced and sold in China will bear a new warning label containing letters that will be no less than 4 millimeters in height. That will be twice the size of the current minimum, which stipulates that the letters be at least 2 mm from bottom to top, according to a notice written by the China National Tobacco Corp and published on the State Tobacco Monopoly Administration's website. Despite the intentions, many tobacco-control experts said the step is "minor" and that it fails to deal with the chief issue. "There is no use in making the font size even 100 times bigger if the warning is pointless," said Wu Yiqun, deputy director of the ThinkTank Research Center for Health Development, a Beijing-based non-governmental organization that advocates for the adoption of stronger smoking-control measures. Both Wu and Yang Gonghuan, director of the tobacco control office of the Chinese Center for Disease Control and Prevention, said the warning that now appears on cigarette packs is too weak. It says: "Smoking is harmful to your health. Quitting early is good for your health." "The package should inform consumers of the dangers of smoking in accordance with requirements adopted by the World Health Organization Framework Convention on Tobacco Control. (It should say that) smoking causes lung cancer, coronary disease and makes people grow old," Yang said. China decided in 2005 to ratify the convention, which also requires that tobacco warnings cover a third of the surface of cigarette packs. "Even if the size of the words is doubled, it still doesn't meet those standards," Yang said. "The Chinese practice is to draw a line to demarcate a third of a cigarette package, where the warning should be, but the words put on it are still very small." Experts said graphic health warnings could be printed on cigarette packs and used as a "scientific, direct and shocking" deterrent to smoking.Throughout the world, more than 1 billion people in 19 countries live under laws that require the packaging of various types of tobacco products to bear large, graphic health warnings. They often show pictures of black lungs and festering mouth sores, according to the World Health Organization. China, though, is excluded from those rules. Both Wu and Yang said the fundamental barrier to better control of tobacco use in the country is the fact that the China National Tobacco Corp, the country's largest cigarette-maker, is a subsidiary of the State Tobacco Monopoly Administration, China's tobacco regulatory body.
