BEIJING, July 3 (Xinhuanet) -- The Atlantis mission to be launched by NASA on July 8 will not be an end to the space age, as some media suggest.Although it is the final mission of the space shuttle, it will open up "the next chapter" in the United States' space exploration, NASA's administrator Charles Bolden Jr said at the National Press Club in Washington on Friday."When I hear people say - or listen to media reports - that the final shuttle flight marks the end of US human space flight, I have to say . . . these folks must be living on another planet," he said."As a former astronaut and the current NASA administrator, I'm here to tell you that American leadership in space will continue for at least the next half-century because we have laid the foundation for success - and for NASA, failure is not an option," he said.NASA administrator Charles Bolden Jr drew a lot of media attention during his speech at the National Press Club in Washington DC.One of the foundations is the "unprecedented" research capabilities the International Space Station (ISS) now possesses, largely thanks to the space shuttle missions.Although some media imply that "the game will be up" once the ISS is out of orbit in 2020, he said the splendid research results and rich knowledge astronauts and scientists have accumulated through more than 1,200 experiments since 1998 have laid out "a stepping-stone to the rest of the solar system and the tip of what comes next".As NASA turns a new page, it will "focus on deep space exploration", while leaving US private companies to operate low Earth orbit transportation systems for tourism and business, he said.NASA will develop "a deep space crew vehicle and an evolvable heavy-lift rocket," he said. The moon, asteroids and Mars will be the next destinations for humans to live and work, he said."We will maintain and grow US leadership in space and derive all the benefits that flow from it. Tomorrow's space program is taking shape right now," he said.

concerned about weaker economic growth being a reality for most advanced economies."Further mis-steps from European and US policymakers risk converting the cracks in their economies into a much deeper global system crisis which would have worrying economic and?social consequences," he warned.But Smith, whose bank is focusing on Asia to drive profit growth, remains optimistic for the outlook in the Asia-Pacific region.He said that the fact is that Australia is incredibly well positioned because of the nation's linkage to Asia, which remains the best performing part of the global economy.His comments came after ANZ reported a 1.45 billion U.S. dollars underlying profit for the June quarter, up 1.3 percent compared to the March quarter.

WASHINGTON, June 7 (Xinhua) -- Advanced hepatitis C patients with chronic liver disease may benefit from drinking coffee during treatment, according to a new study published Tuesday in Gastroenterology, the official journal of the American Gastroenterological Association Institute.The study shows that patients who received peginterferon plus ribavirin treatment and who drank three or more cups of coffee per day were two times more likely to respond to treatment than non- drinkers.Among non-drinkers, 46 percent had an early virologic response; 26 percent had no detectable serum hepatitis C virus (HCV) ribonucleic acid at week 20; 22 percent had no detectable serum at week 48; and 11 percent had a sustained virologic response. In contrast, the corresponding proportions for those who drank three or more cups of coffee per day were 73 percent, 52 percent, 49 percent and 26 percent, respectively."Coffee intake has been associated with a lower level of liver enzymes, reduced progression of chronic liver disease and reduced incidence of liver cancer," said Neal Freedman, of the National Cancer Institute and lead author of this study. "Although we observed an independent association between coffee intake and virologic response to treatment, this association needs replication in other studies."Approximately 70 to 80 percent of individuals exposed to HCV become chronically infected. Worldwide, these individuals are estimated to number between 130 and 170 million. Higher coffee consumption has been associated with slower progression of pre- existing liver disease and lower risk of liver cancer. However, the relationship with response to anti-HCV treatment had not been previously evaluated.

BEIJING, Sept. 2 (Xinhuanet) -- The amount of space junk orbiting the Earth could cause fatal leaks in spaceships or destroy valuable satellites, according to a report released by the U.S. National Research Council.Computer models have shown that the number of orbital debris "has reached a tipping point, with enough currently in orbit to continually collide and create even more debris, raising the risk of spacecraft failures," the Research Council said Thursday.So far, there are 22,000 pieces of debris large enough to track from the ground, but smaller objects could still cause serious damage.New international regulations are needed to limit space junk.And more researches should be done to test the possible use of launching magnetic nets or giant umbrellas to push the debris further towards the Earth where it would burn up, or into a higher but safer orbit.

BEIJING, June 21 (Xinhua) -- China will launch a new icebreaker for use during an upcoming 2013 polar expedition, a senior oceanic official said on Tuesday.Both the new icebreaker and Xuelong ("Snow Dragon"), an icebreaker that operated in Antarctica, will form an Arctic-Antarctic maritime research team."China will have at least two icebreakers concurrently operating at both the north and south poles," Chen Lianzeng, deputy director of the State Oceanic Administration, told a national conference on polar research, which has been the first since 1984 when the country started expeditions in polar regions.The new icebreaker will boast facilities that will allow it to research the oceanic environment, integrate data for real-time oceanic monitoring, deploy and retrieve detectors and conduct aerial studies using helicopters, Chen said.The two icebreakers will conduct expeditions in polar regions for more than 200 days annually, he said.Fixed-wing aircraft will also be added to the expedition team before 2015, allowing researchers to be transported between China's Zhongshan and Kunlun research stations and Antarctica's Grove Mountains.The Kunlun station went into operation in early 2009 as the first Chinese research station on Antarctica's inland. The Zhongshan station, established in 1989, now serves as a supply base for the Kunlun station.A written comment by Vice Premier Li Keqiang sent to the conference said the polar research, a magnificent feat of the mankind, has great significance for China's oceanic work and sustainable development."Over the past two decades, China's polar research made great achievements and became influential globally," Li said.Li encouraged Chinese scientists to actively participate in international exchanges and cooperation, safeguard national interests and contribute to the peaceful use of polar regions.Since the early 1980s, China has sent 27 Antarctic expedition teams and completed four research missions to the Arctic Ocean.Besides the Xuelong icebreaker, China has built three Antarctic stations -- Changcheng (Great Wall), Zhongshan and Kunlun -- and one Arctic station -- Huanghe (Yellow River) Station.
