NEW DELHI, Oct. 1 (Xinhua) -- Suspected encephalitis has killed over 100 children in the northern Indian state of Bihar since June, reported local media Saturday.At least 51 children in Bihar's Gaya district died of the epidemic in the last seven weeks, in the wake of the death of 55 children in a similar outbreak of the brain disease in another district of the state earlier, reported Indo-Asian News Service.Most of the children belong to a caste known for its absolute poverty.According to district health officials, all children have died at Anugrah Narain Medical College and Hospital in Gaya, about 100 km from the state capital Patna.The children reported high fever, followed by bouts of unconsciousness and convulsions.So far, more than 220 children with suspected encephalitis were admitted for treatment, with over two dozens of the children still battling for life, according to the report.Earlier, Indian Health and Family Welfare Minister Ghulam Nabi Azad has said clinical and epidemiological data suggested that there was an outbreak of acute encephalitis syndrome, resulting in 150 cases and 55 deaths, mostly among children, from early June to mid-July in the Muzaffarpur district of Bihar.

WASHINGTON, Nov. 10 (Xinhua) -- Using its near-infrared vision to peer nine billion years back in time, NASA's Hubble Space Telescope has uncovered an extraordinary population of young dwarf galaxies brimming with star formation, the U.S. space agency announced on Thursday.While dwarf galaxies represent the most common type of galaxy in the universe, the rapid star-birth observed in these newly- found examples may force astronomers to reassess their understanding of the ways in which galaxies form.The galaxies are a hundred times less massive, on average, than the Milky Way, yet they churn out stars at such a furious pace that their stellar content would double in just 10 million years. By comparison, the Milky Way would take a thousand times longer to double its star population.The universe is estimated to be 13.7 billion years old, and these newly-discovered galaxies are extreme even for the young universe -- when most galaxies were forming stars at higher rates than they are today. Astronomers using Hubble's instruments could spot the galaxies because the radiation from young, hot stars has caused the oxygen in the gas surrounding them to light up like a bright neon sign."The galaxies have been there all along, but up until recently astronomers have been able only to survey tiny patches of sky at the sensitivities necessary to detect them," said Arjen van der Wel of the Max Planck Institute for Astronomy in Germany, lead author of a paper on the results to be published online on Nov. 14 in The Astrophysical Journal. "We weren't looking specifically for these galaxies, but they stood out because of their unusual colors. "The observations were part of the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS), an ambitious three- year study to analyze the most distant galaxies in the universe. CANDELS is the first census of dwarf galaxies at such an early epoch."In addition to the images, Hubble has captured spectra that show us the oxygen in a handful of galaxies and confirmed their extreme star-forming nature," said co-author Amber Straughn at NASA's Goddard Space Flight Center. "Spectra are like fingerprints. They tell us the galaxies' chemical composition."The CANDELS team uncovered the 69 young dwarf galaxies in near- infrared images taken with Hubble's Wide Field Camera 3 and Advanced Camera for Surveys.The observations suggest that the newly-discovered galaxies were very common nine billion years ago. However, it is a mystery why the newly-found dwarf galaxies were making batches of stars at such a high rate.

MOSCOW, Nov. 25 (Xinhua) -- Russia's Proton-M carrier rocket was launched on Friday from the Baikonur space center in Kazakhstan with a Chinese communications satellite "AsiaSat-7", according to Russia's Federal Space Agency Roscosmos.Roscosmos' live broadcast on its official website showed that the Proton-M rocket atop the Briz-M upper stage was launched at 23: 10 Moscow time (1910 GMT). The separation of the satellite from the rocket was scheduled for 08:23 Moscow time (0423 GMT) on Saturday.The AsiaSat-7 which belongs to the Asia Satellite Telecommunications Company Limited (AsiaSat) located in Hong Kong, China, is a new generation satellite designed to replace AsiaSat 3S at the orbital location of 105.5 degrees East.The new satellite was expected to support a broad range of applications for the Asia-Pacific region, including television broadcast and VSAT (Very Small Aperture Terminal) networks.

  

JERUSALEM, Dec. 11 (Xinhua) -- Kfir Damari, a communication systems engineer, has a dream: to land a miniature spacecraft on the moon sometime in 2013.Damari is one of the founders of Team SpaceIL, a non-profit organization representing Israel in the Google Lunar X Competition. The prize: 20 million U.S. dollars to the first of the 26 international teams currently registered that lands an unmanned craft on the moon, moves it a minimum of 500 meters across the lunar surface and transmits live high-resolution images back to earth."It's a tough mission, but I believe that if everyone in Israel joins hands it's possible," Damari told Xinhua.It is exactly the kind of entrepreneurial spirit that Israel, a country largely void of natural resources, counts on to make it a global leader in technological innovation.The two other men behind the initiative are Yonatan Winetraub, 25, a systems engineer at Israel Aerospace Industries (IAI) and a graduate of NASA's International Space University, and Yariv Bash, 31, a computer scientist and electronics engineer. The three first met at an innovation conference held by IAI a year ago.They describe the lander as a nano-satellite, whose design was revealed at the project's official inauguration ceremony on Thursday. The vessel weighs 100 kg, 80 percent of which are fuel, and is outfitted with rocket boosters and a panoramic camera."It's somewhat of a cellular phone sitting on a large fuel tank. All the technology that we require is basically contained in a typical smartphone with its communication and imaging features," Damari said.Launched in 2007, the Lunar X Prize aims to encourage space enthusiasts and engineers worldwide to develop cheap technologies for robotic space exploration.The Israelis have slated a modest 15 million U.S. dollars for the endeavor, 90 percent of which must come from private contributions according to the competition's rules. They have already raised 3.5 million dollars.The fact that they have formed a non-profit NGO in itself is worthy of praise. Most other teams have obtained the patronage of private corporations for whom money is not a problem, with some reportedly allotting up to 100 million U.S. dollars.To compensate for the disparities in funding, Damari and his partners have enlisted the support of 120 local volunteers, many of them engineers holding top positions in the technological and scientific community as well as the country's leading defense industries.Rona Ramon, the widow of Israeli astronaut Ilan Ramon killed aboard the Columbia Space Shuttle in 2003, was one of the sponsors too.In a bid to keep costs down, SpaceIL is heavily relying on the existing knowledge accumulated by Israel's defense industries over the past decades in building and launching mainly small, lightweight communications and military surveillance satellites into space.The challenge, Damari said, is to take that know-how a step further. The professionals who have volunteered for the project, among them some of Israel's most revered space experts, are currently grappling with several issues, including the ignition system, optic-visual navigation, beaming imagery to earth and the intricacies of enabling the nano-satellite a smooth lunar landing.SpaceIL is still searching for a third party that they will lease to launch their vehicle into space. Once there, they will have to navigate it to the moon on their own.While 20 million U.S. dollars is a major motivator for anyone, the Israelis said they're not seeking personal gain, but rather plan to invest the prize money in the vision that originally prompted their registration in December last year: inspiring the country's younger generation to pursue engineering and the sciences and to dream big, just like Neil Armstrong did when he disembarked from the Apollo 11 and took the first step on the moon in 1969.The funds, they said, will be funneled to educational programs that seek to rejuvenate youths' interest in science disciplines, which have been on the decline in the country's high schools in recent decades."We hope to attract the next generation of kids, to enable them to be engineers and scientists and to make sure that we have more people that can build spaceships in Israel in the future," said Damari.He and the other men behind the initiative also acknowledge that their motives are no less driven by patriotism. Winning the Lunar X has the potential to create national pride and put Israel "on the map as a start-up nation" by accomplishing a feat reserved for superpowers."The moon is something you see every day. I think that for me personally, space exploration is the way to enlist the nation to do something that has not yet been done," said Damari, who started programming aged six and wrote his first computer virus aged 11."It's also about exploring new borders, going the distance. (The project) will leverage Israel's space industry. I'm sure that all the industries that will partner with us will learn a lot and develop new applications, especially for the civilian market," he said.On Thursday, Israeli President Shimon Peres, whose name has become synonymous with the nation's hi-tech industries, honored the trio by unveiling their model at the ceremony held at MABAT -- IAI's missiles and space division near Tel Aviv."More than Israel is leading technology, it is likely to lead Israel. It's the key to our economy ... If they win the prize, and I'm sure they will, it will also reward Israel with the deepest appreciation and the best deterrence," Peres told a crowd of senior executives from local defense industries."I admire your audacity and vision," he complimented the three scientists.Will they realize their ambition? Damari expressed humble optimism, "It's not easy, but certainly possible ... We believe we can win."

  

UNITED NATIONS, Nov. 21 (Xinhua) -- Dramatic progress in science, political leadership, and results indicate that 2011 was a "game changing" year for the international AIDS response, and much progress has been made in 2011 to check AIDS-related deaths since 1997, the peak of the epidemic, a new report released by the Joint United Nations Program on HIV/AIDS (UNAIDS) said on Monday."The Report on the Global AIDS Epidemic 2011" found that new infections were reduced by 21 percent since 1997, and deaths from AIDS-related illnesses decreased by 21 percent since 2005, according to the report.Furthermore, 47 percent (6.6 million) of the estimated 14.2 million people eligible for antiretroviral therapy treatment in low- and middle-income countries were accessing treatment, in increase of 1.35 million people since 2009.The report also found early signs that HIV treatment is having an impact on reducing the number of new HIV infections. As treatment reduces the viral load of a person living HIV to almost undetectable levels, it also reduces the risk of transmitting the virus to an uninfected partner, according to the report. Studies also show that treatment can be up to 96 percent effective in preventing HIV transmission among couples.Eleven countries, including many Sub-Saharan African countries, reached "close to universal access" for AIDS treatment, which is determined to be 80 percent access, in 2011.Botswana made the most dramatic progress in scaling up access to treatment, the report said. While sexual patterns remained relatively stable in the country since 2000, access to treatment increased from less than 5 percent in 2000 to more than 80 percent in 2011.Despite progress, however, the report does note that 2011 marks an unprecedented high the number of people infected with HIV worldwide.Globally, an estimated 34 million people are currently living with the infection. Approximately 2.7 million got infected with the virus in 2010, and as many as 1.8 million people died of AIDS- related illnesses in 2010.Yet the report also notes estimates that as many as 2.5 million deaths are estimated to have been averted in low- and middle- income countries due to increased access to HIV treatment since 1995."Now is not the time to reduce our efforts despite some good news on reducing new infections. Infections are decreasing, but not rapidly enough," said Kim Nichols, executive director of African Services Committee, on Monday at a press conference."There are fewer AIDS deaths, but with the number of infections increasing, prevention has to be the mainstay of our response," Nichols said.Indeed, the UNAIDS report calls for a new framework for investments which are focused on "high-impact, evidence-based, high-value strategies," according to a press release from the UNAIDS website.The framework, which aims to achieve universal access to treatment and prevention centers by 2015, requires a 22-24 billion US dollar funding increase by 2015.Given the withering state of the global economy -- donor funding for the AIDS response has dropped from 7.6 billion in 2009 to 6.9 billion in 2010 -- raising that kind of money may be a long shot. Regardless, UNAIDS'new investment plan calls for smarter uses of less money.According to the report, the framework will focus on high-risk populations like sex workers, men who have sex with men, and people who inject drugs and prevent infections among children, as well as invest in behavior change programs, condom promotion, and treatment, care and support for people living with HIV."The world faces a clear choice: maintain current efforts and make incremental progress, or invest smartly and achieve rapid success in the AIDS response," says the UNAIDS report.
