HOUSTON, July 25 (Xinhua) -- A shelter-in-place was ordered after a battery caught fire during a testing at NASA's Johnson Space Center Monday morning.A battery was being tested inside a containment system when it got overheated and caught fire at about 9 a.m. local time, ABC quoted the Houston Fire Department (HFD) sources as reporting.A shelter-in-place was issued for a few buildings because it's believed that one of the bi-products of the combustion could be dangerous, HFD said.The fire was put out before 11:30 a.m.A firefighter was injured when a hydrant cap blew off and struck him, according to ABC.

SYDNEY, Aug. 2 (Xinhua) -- Australia's general practitioners ( GPs) will not back the idea of routine prostate cancer tests for men as young as 40 despite growing calls for regular screening, the nation's largest professional general practice organization said on Tuesday.Spokesman for the Royal Australian College of General Practitioners (RACGP), Professor Chris Del Mar said there was not enough solid evidence to suggest major benefits from routine screening and that current tests were unable to detect "nasty" and potentially deadly forms of prostate cancer from ones that will not cause any harm."The problem is you end up treating lots of people who don't need to be treated," Del Mar said, adding that treatment could leave men impotent and with incontinence problems."You will treat 20 times as many people than would have ever been bothered by it. We don't yet know that treating prostate cancer is better than not treating it. We are not sure it does any good and could be doing more harm," he said.On the other hand, Australia's urologists and pathologists both want men aged 40 and over who are worried about developing the disease to be offered tests.The Royal College of Pathologists (RCPA) on Tuesday released an official recommendation on routine screening for men aged 40 and over if they were concerned about prostate cancer.The pathologists argue that blood tests for prostate cancer in men under 50 can predict their future risk of developing the disease by measuring their prostate specific antigen levels (PSA).They say that men with high PSA levels for their age should be tested annually, while those PSA levels are below the average could be tested less frequently.Their call for more routine testing contrasts with recommendations for GPs, whose `Red Book' medical guide does not support regular screening.Instead, it suggests GPs should inform men aged 50-70 of the risks and benefits of screening and only test if the patient requests one.RACGP spokesman Del Mar, who co-wrote the RACGP's recommendations, said while the Red Book was being revised "we are not going to liberalize it".Prostate cancer is one of the most common forms of cancer in Australia.About 20,000 cases of prostate cancer are diagnosed each year, with 3,300 men dying.Given the debate around prostate cancer tests, the Royal College of Pathologists wants to work with GPs, urologists and other medical organizations to develop a consensus on how and when to test for the disease, in a similar way to how experts approach breast cancer."It would be a good outcome for prostate cancer if we worked towards developing more of an umbrella document which reflected consensus among different stakeholder organizations. ," RCPA President Paul McKenzie said.

SAN FRANCISCO, June 13 (Xinhua) -- Social networking giant Facebook will likely go public in the first quarter of 2012 with a valuation that could top 100 billion U.S. dollars, U.S. media reported on Monday.In a report, CNBC quoted people familiar with the matter as saying that Facebook could submit filing to register its securities with the U.S. Securities and Exchange Commission (SEC) as early as October or November this year.People who are on Wall Street and track this information told the business news television channel that they think the Facebook initial public offering (IPO), if and when it happens could value the company of more than 100 billion dollars.A factor in the company's IPO timing is the SEC's requirement that companies must disclose financial information if they have more than 500 private investors."The company has until the end of April 2012 to disclose their financials, but they may just want to get ahead of that by doing a formal initial public offering, I'm told. And that could happen in the first quarter of the year," said CNBC Wall Street reporter Kate Kelly.Facebook is also facing internal pressure as employees have not been permitted to sell their private shares on the secondary market since last spring. An IPO would make it easier for employees to monetize their shares, said Kelly, citing sources.Facebook shares have been traded in private markets such as Sharepost.com, which puts the social networking company's valuation at 85 billion dollars.Meanwhile, latest data show that Facebook is losing users last month in the United States, Canada and several European countries, indicating that the company could have hit the limits of expansion in its mature markets.

SINGAPORE, June 14 (Xinhua) -- Researchers from Singapore and China are conducting a research aimed at using different technologies to completely capture and convert carbon dioxide in industrial emissions into energy, local daily Lianhe Zaobao reported on Tuesday.The project, supported by the National Research Foundation (NSF) of Singapore, will make use of sunlight as well as photochemical and photosynthetic processes, the foundation said.The researchers involved in the five-year project are from China's Peking University and Singapore's National University of Singapore and the Nanyang Technological University. A research center will be established under the Campus for Research Excellence and Tehnological Enterprise, a program also known as CREATE, the foundation said.It will be the first project involving cooperation with a Chinese university under the program. It will be located at the University Town of the National University of Singapore due to be completed by the end of the year.Lee Yuan-Kun, a researcher at the National University of Singapore, said no single chemical process can capture and convert the carbon dioxide completely so the researchers will be first treating the emissions with photochemical and electrochemical processes to convert most of the carbon dioxide into energy resources such as methane.The gas with thinner carbon dioxide will then be used to grow microalgae, he said.Nevertheless, for the cost of renewable energy to be close to that of fossil fuel, the efficiency will have to be drastically improved by about five to 10 times, Lee said.The project is one of three energy research projects to be housed under the Campus for Research Excellence and Tehnological Enterprise program.Zhang Dongxiao, from the College of Engineering at Peking University, said that the research program seeks to develop energy efficient and environmentally friendly carbon capture technologies that can be applied in the manufacturing and chemical industries, and that it complements Peking University's strong capability in carbon storage."Reducing carbon intensity will not only benefit both countries in terms of cost competitiveness of products made, but also portrays a good image on our national responsibility to achieve a sustainable Earth," Zhang said. 

UNITED NATIONS, June 8 (Xinhua) -- Marking 30 years of the HIV- AIDS pandemic, scores of heads of state and government and ministers took to the UN General Assembly podium on Wednesday to list their country's accomplishments and list challenges in the battle.The General Assembly High Level Meeting on AIDS is taking place 10 years after the UN Special Session on HIV/AIDS and also marks five years since signing of the Political Declaration in which UN member states committed to moving towards universal access to HIV prevention, treatment, care and support.UN Secretary-General Ban Ki-moon UN recalled how three decades ago AIDS was spreading while "Today, we have a chance to end this epidemic once and for all."Now, instead of fear, there is hope, he said."Today, HIV is on a steep decline in some of the most affected countries. Countries like Ethiopia, South Africa, Zambia and Zimbabwe," he said. "They had the largest epidemics in the world, and they have cut infection rates by one quarter.""Globally, more than 6 million people now get treatment," Ban said. "All of these advances come thanks to you and the commitments you made, first 10 years ago and then again in 2006. Today, the challenge has changed. Today, we gather to end AIDS."However, President Joseph Deiss of the General Assembly said 10 million people still have no access to treatment and far too many people were still being infected, adding it was necessary to continue complementary and closely-linked prevention, treatment, care and support measures."We have reached a critical moment in time," he said. "We must take a holistic approach and integrate the response to AIDS into broader development programs."Michel Sidibe, executive director of the Joint UN Program on HIV/AIDS (UNAIDS), recalled how 30 years the disease was called the gay plague and slime disease. People were afraid of each other and there was no hope."This image should not disappear. It is part of our history," he said.Sidibe said the AIDS movement was the story of a people breaking the conspiracy of silence, demanding equity and dignity, confronting societies'wrongs, seizing their rights, and making a passionate call for social justice. Since then, a compact had been made between the global North and the South, which had produced lifesaving results.Now, More than 6.6 million people are being treated in low- and middle- income countries, he said, pointing out that since the initial success stories in Uganda and Thailand 56 countries, including 36 in Africa, have been able to stabilize the epidemic and reduce the number of infections significantly.Infections have been reduced by 35 percent in South Africa and by more than half in India, the UNAIDS chief said. In China, the HIV mortality rate had fallen by 64 percent, Sidibe said. Many other countries had reached universal access to treatment.He voiced what was repeated several times, and that was a call for "a transformational agenda" of "zero infections, zero discrimination and zero AIDS-related deaths."To put a personal face on the disease, a woman from Ukraine openly living with HIV, Tetyana Afansiadi, told her story to the delegates.She told how she had been living with HIV and using drugs for 13 years, had hepatitis C for almost 11 years but now has a husband and an 8-year-old son. Neither have HIV.Three years ago she took part in a drug therapy program that has enabled her to live, work, and take care of her son."Drug dependency and HIV-infection require treatment, not prosecution," she said.Given that opioid substitution therapy in her home city had changed the lives of people like her, it was time to stop refusing antiretroviral treatment to people who used drugs.While the heads of states and government and ministers, usually those heading up health departments, spoke in the General Assembly hall under bright lights, scores more of delegates attended five panel sessions and about 40 individual side events.Some samplings from the spotlighted dark-green podium in the great hall:President Paul Kagame of Rwanda, said, "It is time to galvanize member states to commit to a transformative agenda that overcomes the barriers to an effective, equitable and sustainable response to HIV and AIDS."Jose Angel Cordova Villalobos, health minister of Mexico, called for states to implement friendly, non-discriminatory healthcare systems as well as sex education in order to prevent the spread of HIV/AIDS."To achieve this, we call to all the countries congregated here today in order that your actions are based in the framework of respect to the human rights and focusing on gender equity, that allow to consolidate an effective response to the HIV/AIDS without stigmas, discrimination, homophobia, transphobia; as well as any type of violence," he said, referring, in part, to transsexuals.The vice president of Mauritius, Monique Bellepeau, said, "The adverse impact of the AIDS epidemic on the socioeconomic progress, particularly in the developing countries, dictates that there is no time for complacency."She added, "After wrestling with AIDS for the past three decades, we are today equipped with a vast body of knowledge and various new tools to urgently complete the task. No less than strict prevention efforts and universal access to treatment, care and support are required."The speeches continue Thursday and on the final day of the three-day meeting, UN member states are expected to adopt a declaration to guide country responses to HIV over the next five years.
