BEIJING, Jan. 21 (Xinhua) -- Chinese Vice Premier Hui Liangyu on Friday urged local governments to step up efforts in protecting agricultural production as winter wheat growing regions in the north of the country have been suffering due to the prolonged drought.Hui warned that the drought could cause great harm to agricultural production.Rainfall in north China, including provinces of Shanxi, Hebei and Shandong, has decreased 20 to 90 percent from the average rain in the same period since October last year.Chinese Vice Premier Hui Liangyu (C) speaks at a meeting on anti-drought and disaster reduction, in Beijing, capital of China, Jan. 21, 2011. Hui Liangyu on Friday urged local governments to step up efforts in protecting agricultural production as winter wheat growing regions in the north of the country have been suffering due to the prolonged drought.Hui urged local departments to improve meteorological monitoring and analysis of the drought, and provide training and services to farmers in order to reduce losses brought about by scarce rain.He also called on local governments to step up construction of more water conservancy projects to better cope with dry weather.Meanwhile, the drought in the north is compared with the intensive icy rain and snow in south and southwest China. A lingering cold spell has been wrecking havoc in these regions, disrupting vegetable production, transportation, and supplies of daily necessities.Hui said the central government would also beef up support in helping these affected regions resume agricultural production as soon as possible.

LOS ANGELES, April 7 (Xinhua) -- Using NASA's Galaxy Evolution Explorer (GEE) satellite, U.S. astronomers are hunting for nearby, hard-to-see stars which could very well be home to the easiest-to-see alien planets, it was announced on Thursday.U.S. astronomers are ferreting out the new targets after the glare of bright, shining stars has frustrated most efforts at visualizing distant worlds, NASA's Jet Propulsion Laboratory (JPL) said.So far, only a handful of distant planets, or exoplanets, have been directly imaged. Small, newborn stars are less blinding, making the planets easier to see, but the fact that these stars are dim means they are hard to find in the first place."Fortunately, the young stars emit more ultraviolet light than their older counterparts, which makes them conspicuous to the ultraviolet-detecting GEE," JPL said in a press release."We've discovered a new technique of using ultraviolet light to search for young, low-mass stars near the Earth," said David Rodriguez, a graduate student of astronomy at University of Californian, Los Angeles. "These young stars make excellent targets for future direct imaging of exoplanets."Young stars, like human children, tend to be a bit unruly -- they spout a greater proportion of energetic X-rays and ultraviolet light than more mature stars. In some cases, X-ray surveys can pick out these youngsters due to the "racket" they cause. However, many smaller, less "noisy" baby stars perfect for exoplanet imaging studies have gone undetected except in the most detailed X-ray surveys. To date, such surveys have covered only a small percentage of the sky, according to JPL in Pasadena, Los Angeles.Rodriguez and his team figured that the GEE, which has scanned about three-quarters of the sky in ultraviolet light, could fill this gap.Astronomers compared readings from the telescope with optical and infrared data to look for the telltale signature of rambunctious junior stars. Follow-up observations of 24 candidates identified in this manner determined that 17 of the stars showed clear signs of youth, validating the team's approach, JPL said."The Galaxy Evolution Explorer can readily select young, low- mass stars that are too faint to turn up in all-sky X-ray surveys, which makes the telescope an incredibly useful tool," Rodriguez said in the release.

WASHINGTON, March 24 (Xinhua) -- The U.S. Food and Drug Administration (FDA) on Thursday approved the use of Zostavax, a live attenuated virus vaccine, for the prevention of shingles in individuals 50 to 59 years of age. Zostavax is already approved for use in individuals 60 years of age and older.In the United States shingles affects approximately 200,000 healthy people between the ages of 50 and 59, per year. It is a disease caused by the varicella-zoster virus, which is a virus in the herpes family and the same virus that causes chickenpox.After an attack of chickenpox, the virus lies dormant in certain nerves in the body. For reasons that are not fully understood, the virus can reappear in the form of shingles, more commonly in people with weakened immune systems and with aging."The likelihood of shingles increases with age. The availability of Zostavax to a younger age group provides an additional opportunity to prevent this often painful and debilitating disease" said Karen Midthun, director of FDA's Center for Biologics Evaluation and Research, in a statement. ( Shingles is characterized by a rash of blisters, which generally develop in a band on one side of the body and can cause severe pain that may last for weeks, and in some people, for months or years after the episode.Approval was based on a multicenter study conducted in the United States and four other countries in approximately 22,000 people who were 50-59 years of age. Half received Zostavax and half received a placebo. Study participants were then monitored for at least one year to see if they developed shingles. Compared with placebo, Zostavax reduced the risk of developing shingles by approximately 70 percent.The most common side effects observed in the study were redness, pain and swelling at the site of injection, and headache, according to the FDA.Zostavax, manufactured by Merck & Co., was originally approved on May 26, 2006, for the prevention of shingles in individuals 60 years of age and older.

SAN FRANCISCO, April 22 (Xinhua) - Amazon's web-services disruption issues have not been completely resolved Friday morning, as some websites still in slow recovery.Amazon said in an update early Friday that meaningful progress has been made and is expected to continue over the next few hours.Reddit, a social news website, said on its homepage that "we are slowly getting our capacity back," and users may be able to log in if lucky. Some sites appeared to have recovered, including location-based social networking site Foursquare and HootSuite, an online brand management and social websites monitoring service.Amazon has not released the number of companies which have been disrupted by the outage and when the web-services will fully recover.The outage highlights risks of relying on public cloud service. Security and reliability have been experts' concerns on public could web-hosting service. Many Internet startups have been relying on the service to bring their costs down.Elastic Compute Cloud (EC2) is a central part of Amazon's cloud computing platform Amazon Web Services. It allows users to rent virtual computers on which to run their own computer applications. The European Space Agency, PBS and Ericsson are all among its cloud service customers.According to Amazon's Service Health Dashboard, errors began at 1:41 a.m. PDT Thursday in its datacenter in northern Virginia, saying "instance connectivity, latency and error rates."

MOSCOW, April 12 (Xinhua) -- Does life exist on other planets beyond the solar system? Are there any other planets like the Earth in our universe? And what does the universe look like?On questions related to outer space, human beings have never stopped observing and thinking.Yuri Gagarin, who made the first manned space flight on April 12, 1961, and orbited Earth for 108 minutes before safely landing, opened a window named "space" to humankind. The Soviet cosmonaut's journey continues to be an inspiration for the world to "conquer" space -- but now for more peaceful purposes.After the Cold War, cooperation on space exploration and scientific researches has turned to a more pragmatic way. More and more countries are realizing that space programs are closely linked with their people's lives than ever before.GAGARIN'S LEGACY INSPIRES PEACEFUL COOPERATION IN SPACEThe UN General Assembly adopted a resolution earlier this month that declares April 12 the International Day of Human Space Flight. The resolution has been supported by more than 60 countries."Man's space odyssey, the fruitful cooperation of many states in outer space would have been impossible without the very first step, Yuri Gagarin's flight," said Vitaly Churkin, Russia's permanent representative to the United Nations.However, the first human space flight was actually a result of competition between the East and the West at the height of the Cold War when the Berlin Wall was built.That competition gradually evolved, however, into a joint space project that has drawn more than 15 nations -- the International Space Station (ISS). Such a project would almost impossible to imagine before.The Mars-500 project in Moscow, aimed at testing the physical and psychological strains on humans during a 500-day journey to "Mars," is another good example of the international cooperation in scientific research. The experiment included six crew members from four countries, including Russia, China, France and Italy.Compared with the times of Gagarin, who died in a 1968 plane crash,mankind has changed its approach to space exploration, rendering it more pragmatic. That's according to cosmonaut Pavel Vinogradov, now a deputy head of the Space Flight Center in the Energy Rocket-Space Corporation."Early romanticism and space race have gone. Countries have been replaced by the business-oriented cooperation in the recent decade," Vinogradov told Xinhua.Experts said the scale and costs of space explorations require massive international cooperation."Space programs have been more money-thirsty even than military programs, so the nations seek closer cooperation," Vinogradov said, "and this pays off."STARDUST YIELDS TO PRAGMATISMUnlike 50 years ago, space technologies now are more closely linked to people and more directly affect their daily lives. Nowadays, one just cannot imagine life without satellite TV or GPS.Veteran cosmonaut Georgy Grechko said orbits have become construction sites rather than military facilities and the space industry itself has swiftly evolved into just another sector of the global economy.Echoing Grechko, Vinogradov said space also is a testing ground for many other sectors, including the bio-technological and pharmaceutical industries."What is just as important, outer space has turned into a platform for close, open, and fruitful international cooperation for the benefits of global, universal peace and development," Russian President Dmitry Medvedev has said.UN General Assembly President Joseph Deiss has said that the newly established International Day of Human Space Flight should serve as an opportunity to reflect on the importance of peaceful use of space to develop essential technologies and scientific breakthroughs."Space technology is used in matters diverse, such as the fight against climate change, against desertification, and against the loss of biodiversity," Deiss said. "The satellite images provided have given essential data when it comes to avoiding the risks of natural disasters."So far, mankind has never stopped making progress beyond the earth's boundaries and the progress itself has never stopped sparking people's imagination about what is possible through the peaceful use and exploration of outer space.What's more, humankind has never stopped the space dream."The task of the government is to inject into the people an ability to dream," said Igor Zadorin, a member of Russia's National Strategy Council.Here is interesting news: NASA's head Charles Bolden arrived in Russia on the eve of Gagarin's flight anniversary and was expected to discuss Russia-U.S. cooperation on a joint flight to Mars by a nuclear-powered spacecraft.What can we expect in the future?
