WASHINGTON, Nov. 8 (Xinhua) -- NASA plans to add an unmanned flight test of the Orion spacecraft in early 2014 to its contract with Lockheed Martin Space Systems for the multipurpose crew vehicle's design, development, test and evaluation, the U.S. space agency announced Tuesday.This test supports the new Space Launch System (SLS) that will take astronauts farther into space than ever before, and provide the cornerstone for America's future human spaceflight efforts."President Obama and Congress have laid out an ambitious space exploration plan, and NASA is moving out quickly to implement it," NASA Associate Administrator for Communications David Weaver said in a statement. "This flight test will provide invaluable data to support the deep space exploration missions this nation is embarking upon."Orion is part of the now defunct Constellation program canceled under President Barack Obama's 2011 budget proposal. Instead Obama urged NASA to work toward sending humans to an asteroid and then on to Mars -- and NASA says it wants to go ahead with that as quickly as possible.This Exploration Flight Test, or EFT-1, will fly two orbits to a high-apogee, with a high-energy re-entry through Earth's atmosphere. Orion will make a water landing and be recovered using operations planned for future human exploration missions. The test mission will be launched from Cape Canaveral to acquire critical re-entry flight performance data and demonstrate early integration capabilities that benefit the Orion, SLS."The entry part of the test will produce data needed to develop a spacecraft capable of surviving speeds greater than 20,000 mph and safely return astronauts from beyond Earth orbit," Associate Administrator for Human Exploration and Operations William Gerstenmaier said. "This test is very important to the detailed design process in terms of the data we expect to receive."

YANGON, Nov. 10 (Xinhua) -- Myanmar surgeons have successfully separated the fifth conjoined twin baby girls, official media reported Thursday.The surgical operation by Dr. Htoo Han and his assistants was performed on the two-year-and-one-month-old conjoined twins named Ma Ingyin Khaing and Ma Ingyin Hlaing in the Children's Hospital in Yangon Wednesday, according to the New Light of Myanmar daily.The separated twins, who are under extensive care in the hospital, are from Kawtin village in Laungton township in southern Tanintharyi region.Myanmar surgeons had carried out four successful similar surgical operations on twins in the past over two decades.The fourth twins, who are also baby girls named So Pyay Lin and So Pyay Win with their chests joined together, were successfully separated in October 2009.

KUNMING, Dec. 11 (Xinhua) -- By moonlight, Ma Yuanqiong, a grassroots AIDS prevention practitioner, and her colleagues slipped into a large community of migrant workers in the city of Jinghong in southwest Yunnan province.As usual, they were greeted tepidly. A dozen sex workers living in the community came to obtain free condoms and brochures on AIDS prevention and quickly dispersed."We visit these women every week. They are familiar with us, but rarely talk about themselves," said Ma, who is in charge of an AIDS prevention program targeting sex workers in Jinghong. The program was initiated by Fuhua International, a local NGO.Sex workers are highly sensitive and vigilant due to safety concerns, since sexual services are illegal in China, Ma said. They have become harder to find since local police started a persistent crackdown on prostitution two years ago and drove many sex workers underground, she said.INACCESSIBILITY IMPEDES EFFORTSJinghong is located in Xishuangbannan Dai autonomous prefecture. Bordering Laos and Myanmar, it's a famous tourist city where the underground sex industry thrives.The AIDS prevention program, which began in 2006, is aimed at improving sex workers' awareness of the epidemic -- which is primarily sexually transmitted -- and prompting them to change risky behavior.In the beginning, program workers quickly realized they faced a significant challenge. "We were often rejected, or even threatened when trying to get in touch with the sex workers at first," Ma said.But the practitioners persisted, approaching nonjudgmentally and treating them as friends, and eventually their efforts began to pay off.During the past five years, the program has provided free condoms and AIDS consulting services to more than 400 sex workers aged 14 to 58 and from many parts of the country, according to Ma.The program has even helped several sex workers give up the business and pursue legitimate careers.However, the organization currently only keeps in touch with about 100 sex workers and has found it more difficult to reach more.The police crackdown has made the sex workers, especially low-paid street hookers, more mobile and less visible, and Ma pointed out that low-paid sex workers are in greater need for outreach as they are more vulnerable to HIV infection than their their higher-paid counterparts."Low-level sex workers are at a heightened risk, as they and their clients, mainly migrant workers and the elderly, all have insufficient knowledge of the disease," she said.According to statistics provided by the provincial disease control and prevention center (CDC) of Yunnan, about 1.6 percent of sex workers in Yunnan have contracted HIV, while the ratio among the low-level group is 3 percent.By the end of October, Yunnan reported 93,567 HIV carriers and AIDS patients, the most among all provinces, autonomous regions and municipalities."We conducted a survey in Jinghong and neighboring Menghai County at the end of 2008 and found that low-level sex workers almost never used condoms then," said Kang Jun, head of the HIV/AIDS prevention and treatment office in Xishuangbanna.The survey also found that the low-level sex workers only charged about 20 yuan (3.2 U.S. dollars) for each service, and every day they received 16 clients on average, according to Kang.Ahead of the police crackdown, Kang and his colleagues had provided HIV testing services for more than 30 low-level sex workers, and the results showed that two of them had been infected by the virus."The testing work was forced to halt as the crackdown began soon and we could hardly find them," Kang said.The good news, he said, was that the local CDC will launch a four-year investigation on sex workers in Xishuangbanna next January as part of a massive state-funded research project.

BEIJING, Oct. 13 (Xinhuanet) -- A new study finds that ginger may decrease the risk of colon cancer through diminishing the inflammation in the gut, according to media reports Thursday.Prior researches have found that chronicle inflammation in the gut is related to colon cancer, suggesting easing inflammation in intestines might reduce the risk of the cancer, said Suzanna M. Zick, lead author of the study published online in Cancer Prevention Research. Zick, also a naturopathic physician and research associate professor at University of Michigan Medical Center, and her colleagues, assigned 30 volunteers to take pills containing two grams of either placebo powder or ginger root extract, equivalent to about two tablespoons of ground-up raw ginger root.And they recorded the inflammations in the participants' intestines before and after the test period.The researchers found that participants taking ginger pills had 28 percent less inflammation in their intestines after the test. But no difference was found in those who took placebo.The findings are promising, but the researchers are not yet recommending people start taking more ginger at meal times. The study only involved 30 participants, so it is just a preliminary study. Zick said they hope to launch a larger study in the future, according to USA Today.

SANYA, Hainan, Dec. 4 (Xinhua) -- The five BRICS nations intend to focus and work together on developing alternative energy sources.When Bu Xiaolin, vice governor of China's coal-rich Inner Mongolia autonomous region, spoke over the weekend in front of hundreds of BRICS delegates on regional energy strategies, she mentioned little of the fossil fuels that have long contributed to the region's growth.Like many other speakers at the 1st BRICS Friendship Cities and Local Governments Cooperation Forum, which ran from Dec. 1-3 in Sanya, Hainan province, she devoted large part of her speech to discussing wind and solar energy."Facing the prospects of running out of fossil energy and the related environmental issues, developing new energy is an inevitable choice," said Bu.The forum at this seaside resort over the weekend attracted hundreds of local governors, scholars and business people from the BRICS nations -- Brazil, Russia, India, China and South Africa -- to discuss city-to-city cooperation, and new energy was among the top agenda topics.Consensus had been reached at the forum that the five countries should strengthen dialogue and cooperation for provincial and local partnerships, including infrastructure, green economy and technology transfer."We are very willing to cooperate with BRICS countries on new energy innovations, promotion and market development," said Bu.According to Bu, Inner Mongolia has huge potential in new energy, with 380 million kilowatts of exploitable wind power resources, accounting for more than half of China's on-shore wind power resources.The region is aiming for a total installed capacity of 33 million kilowatts for wind power and one million kilowatts for solar power by the end of 2015, she added.At national level, the Chinese central government expects to bring the country's total wind power installed capacity up to 150 million kilowatts in the next five years, according to national development plans.Meanwhile, in Brazil, there is movement to replace fossil energy with new energy in daily use, said Jailson Lima Da Silva, State Representative of the National Union of State Legislatures of Brazil.The country is working to increase the nation's wind power capacity, and new energy is expected to account for 65 percent of the nation's total energy consumption, he said."Brazil is optimistic on wind power exploitation, which will be one of the major fields of future investment," he said.Silva expressed hopes to work with China on new energy, especially solar power and biomass energy. "Brazil has large potential in solar energy, while China is a leading producers of solar equipment," he said.According to Mlibo Qoboshiyane, a member of the Executive Council of Eastern Cape, South Africa, the African nation is also investing extensively in wind and solar energy.South Africa has just unveiled a 12-billion-U.S.-dollar program on renewable energy development, which would largely be spent on wind and solar power and reduce the use of traditional energies, said the official.It would be helpful to exchange technologies and valuable information between the BRICS countries to keep consumption of new energies sustainable and affordable, he said.
