WASHINGTON, May 1 (Xinhua) -- The launch of U.S. space shuttle Endeavour on its final voyage will be no earlier than May 8, after technical problems uncovered last week proved more complex than originally thought, the U.S. National Aeronautics and Space Administration (NASA) announced Sunday.NASA tried to launch Endeavour on Friday on its 25th and final flight to deliver the 2-billion-dollar Alpha Magnetic Spectrometer (AMS) particle detector to the International Space Station. AMS, a particle physics detector, is designed to search for various types of unusual matter by measuring cosmic rays. Its experiments are designed to help researchers study the formation of the universe and search for evidence of dark matter, strange matter and antimatter.The space shuttle Endeavour sits on launch pad 39A as work continues on the shuttle's auxilliary power unit at the Kennedy Space Center in Cape Canaveral, Florida May 1, 2011.However, the launch was called off after engineers detected a failure in one of two heater circuits associated with Auxiliary Power Unit (APU) 1. Heaters are required to keep the APUs' hydrazine from freezing on orbit.NASA hoped Endeavour would lift off on Monday. But further trouble-shooting indicated the glitch was more complicated than officials hoped initially.The failure appears to be a power problem within the aft load control assembly-2, a box of switches controlling power feeds."That basically means the power is not getting out to the heaters that weren't working on launch day," said Space Shuttle Program Launch Integration Manager Mike Moses.

WASHINGTON, May 17 (Xinhua) -- A variation in a gene involved in regulating cholesterol in the bloodstream also appears to affect progesterone production in women, making it a likely culprit in a substantial number of cases of their infertility, a new study from Johns Hopkins University researchers suggests.The Hopkins group has also developed a simple blood test for this variation of the scavenger receptor class B type 1 gene ( SCARB1) but emphasized there is no approved therapy yet to address the problem in infertile women.Following up studies in female mice that first linked a deficiency in these receptors for HDL -- the so-called "good" or " healthy" cholesterol -- and infertility, researchers report finding the same link in studies of women with a history of infertility.The findings has been published on-line this week in the journal Human Reproduction.If the new study's findings hold up on further investigation, the John Hopkins team says they not only will offer clues into a genetic cause of some infertility, but could also lead to a treatment already shown to work in mice."Infertility is fairly common and a lot of the reasons for it are still unknown," warns endocrinologist Annabelle Rodriguez, an associate professor of medicine at the Johns Hopkins University School of Medicine and the lead author. "Right now, the benefit of this research is in knowing that there might be a genetic reason for why some women have difficulty getting pregnant. In the future, we hope this knowledge can be translated into a cure for this type of infertility."

BEIJING, Feb. 1 (Xinhua) -- Senior Chinese official Zhou Yongkang Tuesday called on law enforcement personnel to take more preventive measures against crime and accidents during the Lunar New Year holiday.Zhou, a Standing Committee member of the Political Bureau of the Communist Party of China (CPC) Central Committee, visited community security personnel, a district court, and police patrolling downtown Beijing Tuesday.He also visited a police station that is responsible for keeping public order in the area surrounding the central leadership compound of Zhongnanhai.During his visits, Zhou, who also heads the Commission for Political and Legal Affairs of the CPC Central Committee, said China was seeing the travel peak for the Spring Festival and some regions were suffering icy weather and lingering drought.He asked the police to take effective measures in traffic control and fire-fighting work, and maintain social order during the holiday season.He commended the practice of deploying special police to patrol the surrounding areas of the Tiananmen Square in central Beijing, saying it could deter crime and enable quick responses to emergencies.During his visit to the district court, Zhou warned there were still "many social conflicts."He asked local courts to solve social conflicts more effectively, promote innovative social management and law enforcement in a just and clean manner.The Spring Festival, or Chinese lunar New Year, is the most important festival for Chinese. It falls on Feb. 3 this year.

LOS ANGELES, March 5 (Xinhua) -- Law enforcement agencies are now using smart phones to track and arrest graffiti vandals in Los Angeles, a newspaper report said on Saturday.The graffiti-tracking program, spearheaded by the Tracking and Automated Graffiti Removal System, or TAGRS, allows graffiti- cleaning crews equipped with smart phones to photograph the markings and upload them to a Los Angeles Police Department (LAPD) database, the Los Angeles Times said.The photos are used to gather evidence for prosecution and restitution, the paper quoted city officials as saying.Once the graffiti suspects' identities are discovered, the information is added to the TAGRS database and may eventually uncover incidents involving the same suspects, the paper said.The LAPD launched a pilot project in 2009 in Van Nuys near Los Angeles, modeling its version on one run by the Orange County Sheriff's Department, according to the report.The program is now anchored at four LAPD stations, Van Nuys, Hollenbeck, Central and Harbor, said Mayor Antonio Villaraigosa's spokeswoman Casey Hernandez.Los Angeles spends about 10 million dollars a year cleaning up graffiti, Hernandez said.

BEIJING, Jan. 28 (Xinhua) -- China will further its efforts to harness the Huaihe River over the next five to 10 years in a bid to support the economic development of the regions along the river.The decision was announced Friday in a statement released after an executive meeting of the State Council, China's Cabinet, which was presided over by Premier Wen Jiabao.The work will include upgrading dams and water gates in flood diversion programs and building more irrigation and water conservancy projects in low-lying lands along the Huaihe River, said the statement.Further, efforts will be made to guard against water pollution and help urban and rural residents in the Huaihe River regions have sufficient access to clean water, it said.Also, more flood control reservoirs will be constructed, while more residents will be relocated from flood diversion areas as well as flood land.The cabinet urged government departments to earmark more funds and enhance management and cooperation in implementing these measures.The 1,000-kilometer Huaihe River, the third longest water way in China, originates from Mount. Taibai, central Henan Province, and runs eastward between the Yangtze River and the Yellow River, the two largest rivers in the country. It cuts through Henan and east China's Anhui and Jiangsu provinces before entering the Yangtze River via the Hongze Lake.The flood-prone river has a drainage area of about 180,000 square kilometers.
