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.

CANBERRA, April 14 (Xinhua) -- Scientists on Thursday expressed disappointment to the decision to cancel the long-running Australian Science Festival in Canberra.The festival has been operating during August for the past 19 years with free and ticketed science education activities.However, the festival organizers on Wednesday announced to halt this year's program after failing to secure support from the Australian Capital Territory state government in time to arrange events.According to Australian Science Communicators president, Jesse Shore, thousands of school children have attended the festival over its history to learn more about science as a career."It's encouraged other activities to join it, it was very important in getting National Science Week started, and that's stimulated a lot of other science communication activities," he told ABC News on Thursday.Shore said the decision to close it down is unfortunate as the event has been very influential and instrumental promoting science communications activities.He said he hopes that a number of people would gather together in a new partnership, with new ideas and hopefully a new funding base.

LOS ANGELES, March 4 (Xinhua) -- The California Department of Public Health on Friday announced a recall of hazelnuts which might be contaminated by E. coli bacteria.The department said it ordered the recall after seven people fell sick with E. coli bacteria from eating tainted hazelnuts.The seven illnesses include one in Michigan, three in Minnesota and three in Wisconsin, said Dr. Howard Backer, interim director of the department.The hazelnuts were distributed by DeFranco & Sons, a Los Angeles company, said the department.After being notified of the contamination, the company is voluntarily recalling the nuts, the department said.The hazelnuts affected by the recall were sold under the brand names Sunripe, George Packing, Firestone Farms and Northwest Hazelnut and were distributed nationwide from Nov. 2 to Dec. 22, according to the department.The 50-pound bags of hazelnuts and mixed nuts with hazelnuts may have been repacked or sold from bulk containers, the department said, adding people who had bought the hazelnuts should not eat them.Consumers should check with retailers to determine if their nuts are subject to the recall, and if they are, should discard them, the department added.People who develop symptoms after consuming hazelnuts should seek immediate medical attention, the department suggested.E. coli may cause symptoms that include bloody diarrhea, stomach cramps and dehydration. In extreme cases, patients can suffer potentially life-threatening complication known as hemolytic uremic syndrome, which includes kidney failure.Young children and the elderly are the most vulnerable to the risk.

BEIJING, March 22 (Xinhuanet) -- NASA scientists are testing its next-generation Mars rover, which will land on Mars next year, under extreme conditions at space-simulation chamber in California, media reports said Tuesday.Scientists at NASA's Jet Propulsion Laboratory in Pasadena, Calif., say they've installed the Curiosity rover in a space-simulation chamber that can mimic the environment the probe will encounter on Mars.  After the chamber's large door was sealed last week, air was pumped out to near-vacuum pressure, liquid nitrogen in the walls dropped the temperature to minus 130 degrees Celsius, and a bank of powerful lamps simulated the intensity of sunshine on Mars.After the test period, the rover along with other portions of NASA's Mars Science Laboratory spacecraft including the cruise stage, descent stage and backshell -- part of protective covering -- will be shipped to the Kennedy Space Center for final preparation for the launch window from Nov. 25 to Dec. 18, 2011. Curiosity will study whether a selected area of Mars has offered environmental conditions favorable for microbial life and for preserving evidence about whether Martian life has existed.
