LOS ANGELES, April 7 (Xinhua) -- A new research has found that about nine million people in the United States identify themselves as lesbian, gay, bisexual or transgender (LGBT).About 1.8 percent of adults identify themselves as bisexual, 1. 7 percent as gay or lesbian, and 0.03 percent as transgender, researchers at the University of California-Los Angeles' School of Law said in the study published by The Los Angeles Times on Thursday.The study culled data and methods from nine surveys conducted over the last seven years and averaged results from five of those surveys to estimate sexual orientation and from two surveys to estimate the transgender population.The findings also show that about 8.2 percent of Americans said they participated in same-sex sexual activity and about 11 percent said they had some same-sex sexual attraction, but neither of these groups necessarily identified themselves as LGBT.The researchers noted that insufficient and inconsistent national surveys make it difficult to get an estimate of the LGBT population in the United States, according to the Times report.

BEIJING, Feb. 4 (Xinhua) -- The Chinese government Friday initiated a relief and assistance program for eight drought-ravaged provinces, said a statement on the website of Ministry of Agriculture.The government had implemented a grade II emergency response, meaning a 24-hour alert, daily damage reports, and the dispatching of experts and relief materials, said the statement.The ministry had sent teams to help with relief work in the provinces of Hebei, Shanxi, Jangsu, Anhui, Shandong, Henan, Shaanxi and Gansu, said the statement.The four-month drought had affected 35.1 percent of wheat crops, -- 96.11 million mu (6.4 million hectares) -- accounting for 21.7 percent of total farmland in the provinces, it said.The wheat growing area in the eight provinces accounted for more than 80 percent of the country's total, said the statement.The provinces have received little rainfall since October last year, it said.

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.

WASHINGTON, March 25 (Xinhua) -- NASA's Stardust spacecraft depleted fuel and ceased operation on Thursday after a 12-year run, the U.S. space agency said Friday."This is the end of the spacecraft's operations, but really just the beginnings of what this spacecraft's accomplishments will give to planetary science," said Lindley Johnson, Stardust-NExT and Discovery program executive at NASA headquarters in Washington."The treasure-trove of science data and engineering information collected and returned by Stardust is invaluable for planning future deep space planetary missions."Artist's concept of Stardust spacecraft nearing EarthLaunched on Feb. 7, 1999, Stardust flew past the asteroid named Annefrank and traveled halfway to Jupiter to collect the particle samples from the comet Wild 2. The spacecraft returned to Earth's vicinity to drop off a sample return capsule eagerly awaited by comet scientists.NASA re-tasked the spacecraft as Stardust-NExT to perform a bonus mission and fly past comet Tempel 1, which was struck by the Deep Impact mission in 2005. The mission collected images and other scientific data to compare with images of that comet collected by the Deep Impact.The Stardust-NExT met all mission goals, and the spacecraft was extremely successful during both missions. From launch until final rocket engine burn, it travelled approximately 3.54 billion miles.After the mileage logged in space, the Stardust team knew the end was near for the spacecraft. With its fuel tank empty and final radio transmission concluded, the most traveled comet hunter will move from NASA's active mission roster to retired."This kind of feels like the end of one of those old western movies where you watch the hero ride his horse toward the distant setting sun -- and then the credits begin to roll," said Stardust-NExT project manager Tim Larson from NASA's Jet Propulsion Laboratory in Pasadena, California. "Only there's no setting sun in space."

WASHINGTON, April 3 (Xinhua) -- In the largest study of its kind, researchers from a consortium led by the University of Pennsylvania School of Medicine, the University of Miami, and the Boston University School of Medicine, identified four new genes linked to Alzheimer's disease. The findings appeared Sunday in the current issue of Nature Genetics.Each gene individually adds to the risk of having this common form of dementia later in life. These new genes offer a portal into what causes Alzheimer's disease and is a major advance in the field.The study, conducted by the Alzheimer's Disease Genetics Consortium, reports genetic analysis of more than 11,000 people with Alzheimer's disease and a nearly equal number of elderly people who have no symptoms of dementia. Three other consortia contributed confirming data from additional people, bringing the total number of people analyzed to over 54,000. The consortium also contributed to the identification of a fifth gene reported by other groups of investigators from the United States, the United Kingdom, France, and other European countries.The study is the result of a large collaborative effort with investigators from 44 universities and research institutions in the United States, led by Gerard Schellenberg at University of Pennsylvania."This is the culmination of years of work on Alzheimer's disease by a large number of scientists, yet it is just the beginning in defining how genes influence memory and intellectual function as we age. We are all tremendously excited by our progress so far, but much remains to be done, both in understanding the genetics and in defining how these genes influence the disease process," Schellenberg said.Until recently, only four genes associated with late-onset Alzheimer's have been confirmed, with the gene for apolipoprotein E-e4, APOE-e4, having the largest effect on risk. The Nature Genetics studies add another four -- MS4A, CD2AP, CD33, and EPHA1 -- and contribute to identifying and confirming two other genes, BIN1 and ABCA7, thereby doubling the number of genes known to contribute Alzheimer's disease.
