BEIJING, May 10 (Xinhuanet) -- Researchers from California, Unated States, found that sexual orientation could play a role in cancer and more gay men are reported being cancer survivors than straight men, according to findings in the journal Cancer online Monday.The researchers found that gay men are 1.9 times more likely than straight men to report having had cancer. They also found that lesbian and bisexual women are more than twice as likely as heterosexual women to report fair or poor health after having cancer.Researchers looked at three years of responses to the California Health Interview survey, which included more than 120,000 adults living in the state.Among other health-related questions, participants were asked if they had ever been diagnosed with cancer and whether they identified as gay, lesbian, bisexual, or straight.Out of 51,000 men, about 3,700 said they had been diagnosed with cancer as an adult. While over 8 percent of gay men reported a history of cancer, that figure was only 5 percent in straight men, a disparity that could not be attributed to differences in race, age or income.About 7,300 out of 71,000 women in the study had been diagnosed with cancer, but overall cancer rates did not differ among lesbian, bisexual, and straight women.Ulrike Boehmer, the study's lead author from the Boston University School of Public Health, said higher rates of human immunodeficiency virus (HIV) may be related to the increased risk of cancer in gay men.However, the findings do not necessarily mean that being gay, lesbian or bisexual increases risk of cancer, said the researcher.

You can think of NASA's Discovery program as a sort of outer-space American Idol: every few years the agency invites scientists to propose unmanned planetary missions. The projects have to address some sort of fundamental science question, and (this is the tough part) they have to be relatively cheap to pull off — say, half a billion dollars or so. Then the proposals go through a grueling competition before judges who aren't as nasty as Simon Cowell but who are every bit as tough. The one left standing at the end gets the equivalent of a recording contract: NASA supplies the funding and the launch vehicle, and away the winner goes — to orbit Mercury, as the Messenger spacecraft is doing right now; or to rendezvous with a couple of asteroids, as the Dawn mission will start doing this July; or to smash into a comet on purpose, a feat achieved by Deep Impact in 2005, a mission not to be confused with the movie of the same name. Now it's time for the next contenders. NASA has just announced that the first round of the latest Discovery competition is over, with three entries out of 28 moving on to the finals. They are, in increasing distance from Earth: the Geophysical Monitoring Station (GEMS) lander, which would use seismometers to study the interior of Mars; the Comet Hopper, which would do just that, leaping from place to place across the surface of Comet 46P/Wirtanen to see how different parts of the tumbling body react to heating by the sun; and the Titan Mare Explorer (TiME), which would plop into a sea of liquid hydrocarbons on Saturn's moon Titan — the first oceangoing vessel ever to set sail on another world. If you had to come up with a theme that ties all three missions together, it would be "origins." The Titan explorer, for example, will be studying a place that — in a crude way, at least — resembles the early planet Earth at a time when life arose here. Titan, with a thick atmosphere and a bizarro-world form of weather featuring toxic winds and hydrocarbon rain, is home to a mix of complex chemistry, complete with organic molecules. The oceans provide a medium in which the molecules can move around and interact with each other. It's even conceivable, though clearly a long shot, that some form of microscopic life already exists on this frigid moon. The Mars lander, by contrast, would visit a place where the seas — plain water in this case — vanished long ago. But the mission of GEMS goes far deeper than that. By analyzing Marsquakes on the Red Planet, GEMS will try to get a handle on what the interior of Mars is like. Scientists don't currently know whether the planet's core is liquid, like Earth's, or solid, or some mushy consistency in between. It all depends on how efficiently Mars has cooled since it formed 4.5 billion years ago, and that depends in turn on the planet's internal structure. "That's the mission," says Bruce Banerdt, of NASA's Jet Propulsion Laboratory, the lead scientist for GEMS. "We want to understand how Mars was built." Along with sensitive seismographic equipment, GEMS will drill down about 20 ft. (6 m) with a thermometer-equipped probe, trying to figure out how quickly the temperature rises with depth. "That will let us extrapolate all the way down to the center," Banerdt says, "which will tell us how fast Mars is cooling."

BEIJING, May 19 (Xinhuanet) -- LinkedIn said Wednesday that its stock will debut at 45 U.S. dollars per share, a higher price than the company was expecting even earlier this week, media reports said.The first major U.S. social networking firm to go public, LinkedIn jacked up its initial public offering (IPO) share price for 7.84 million shares to 45 dollars just a week after it first set a target of 32-35 dollars per share.It minted LinkedIn with a market value of more than 4 billion dollars, the highest for a U.S. Internet company taking its first bow on Wall Street since Google Inc. went public nearly seven years ago.The sale could bring in more than 354 million dollars. The company's shares are expected to begin trading on the New York Stock Exchange on Thursday under the symbol "LNKD".LinkedIn has more than 100 million members in over 200 countries and territories. In 2010, the company made 15 million dollars in profit on 243 million dollars in revenue, according to its SEC filing.LinkedIn's biggest shareholder is its founder and chairman, Reid Hoffman, who owns more than 21 percent of the company.

BEIJING, Feb. 24 (Xinhua) -- The Standing Committee of the National People's Congress (NPC) will vote on draft laws on vehicle and boat taxes at the end of its bimonthly sessions on Friday.The group is also expected to vote on protecting the nation's intangible cultural heritage and a draft amendment to the Criminal Law.The Chairperson's Council of the NPC Standing Committee adopted the decision at a Thursday meeting presided over by NPC Standing Committee Chairman Wu Bangguo.The three drafts will undergo further deliberation and revision based upon the opinion of the members of the NPC Standing Committee before the laws are put to a vote.Under the draft law on vehicle and vessel taxes, there will be a reduction in taxes for vehicles with engines smaller than 2.0 liters, which accounts for 87 percent of China's cars. Vehicle owners would also be required to submit tax certificates in order to qualify for a road-worthiness certificate.

SAN FRANCISCO, April 20 (Xinhua) -- Apple Inc. on Wednesday reported record second fiscal quarter results that blow out analysts'expectations, citing strong demands for its products.For its fiscal 2011 second quarter ended on March 26, Apple posted net income of 5.99 billion U.S dollars or 6.4 dollars per share, compared with 3.07 billion, or 3.33 dollars per share a year ago. Its revenue reached 24.67 billion dollars, compare with 13.5 billion in the same period a year earlier.Analysts polled by Thomson Reuters gave an average estimate of 5.35 dollars earning per share on revenue of 23.3 billion."With quarterly revenue growth of 83 percent and profit growth of 95 percent, we're firing on all cylinders," said Steve Jobs, Apple's CEO. "We will continue to innovate on all fronts throughout the remainder of the year."As the most valuable business for the company, Apple sold 18.65 million iPhones in the second quarter, representing 113 percent unit growth over the year-ago quarter. In February, Apple announced that iPhone4 would come on Verizon network, enabling it to attract some 90 million Verizon subscribers to adopt the popular smartphone.The company sold 3.76 million Macs during the quarter, a 28 percent increase over the year-ago quarter, and 9.02 million iPods during the quarter, representing a 17 percent unit decline from the year-ago quarter.The company also sold 4.69 million iPads during the quarter, which is below analysts' projection. Analysts said Apple could have sold more tablets without supply constraints.Wall Street analysts estimated sales of iPad to reach about 6 million in the fiscal second quarter, alongside about 16 million iPhones and 3-4 million Macs.Apple also reported a gross margin of 41.4 percent compared to 41.7 percent in the year-ago quarter. Analyst said the decline of Apple's gross margins can be attributed to two reasons. One reason is the introduction of iPad in 2010 as it is a lower gross margin product than the iPhone. The other is the decline of iPhone margins over years.Supply chain related issues have been analysts' concern in the past quarter as Apple indicated in the Q1 earnings conference call that it could have sold more iPhones and faced some supply related issues. Meanwhile, the Japanese earthquake created more supply related issues for the company as its Japanese suppliers Mitsubishi Gas Chemical and Toshiba are both temporarily shut down to assess damage from the natural disaster.For the third fiscal quarter, Apple CFO Peter Oppenheimer gave an estimated revenue of about 23 billion and profit of 5.03 dollars per share.
