VIENNA, Oct. 7 (Xinhua) -- A sculpture of late Soviet cosmonaut Yuri Gagarin was presented to the UN Office in Vienna (UNOV) Friday to celebrate "50 Years of Human Spaceflight," the theme of the World Space Week 2011.In 1961, Gagarin completed an orbit around the Earth aboard the Vostok 1 spacecraft, serving as a pioneer of human spaceflight.The sculpture is a gift from the Russian government and would be placed at the Permanent Exhibit of the United Nations Office for Outer Space Affairs (UNOOSA).Attendants of the ceremony include UNOV Director-General Yury Fedotov, UNOOSA Director Mazlan Othman and Head of the Russian Permanent Mission Vladimir Voronkov."Outer space is one of the most exciting and challenging topics, and perhaps of all the important topics on the agenda of the United Nations, none quite captures our imagination like outer space," Othman said in her statement.Meanwhile, speaking highly of Gagarin's achievement 50 years ago, Fedotov stressed that the purpose of the development and utilization of outer space must be to the benefit of all mankind.The UN official said that relevant UN agencies would provide technical assistance to all countries to develop outer space and ensure the benefits in peaceful purpose.On Dec. 6, 1999, the 55th United Nations General Assembly declared the World Space Week to be held every year during Oct. 4-10.

CANNES, France, Nov. 3 (Xinhua) -- Chinese President Hu Jintao met here Wednesday his French counterpart Nicolas Sarkozy on bilateral ties and other issues of common concern, including the Group of 20 summit scheduled for Thursday and Friday.Hu pointed out that since the global economic recovery is now burdened by quite a few instable and uncertain factors, the international community has great expectations of the G20 Summit in Cannes."The Chinese side actively supports the French side to host the summit," Hu said, emphasizing that the G20 should continue to uphold the spirit of cooperation and send a clear and definite signal of securing growth and promoting stability to the international community through this summit.Hu expressed the hope that all relevant parties should jointly endeavor to make the Cannes summit a conference of solidarity and win-win cooperation.Sarkozy expressed his appreciation of the effort China has made to prepare for the G20 summit. He said the French side was ready to strengthen coordination and cooperation with the Chinese side and work with all other parties to push for positive results at the summit.Hu said Europe is the largest economy in the world, and there will be no global economic recovery without a recovery of the European economy.He pointed out that the package deal that the European Union (EU) struck lately demonstrates its will and determination to resolve Europe's debt problem. He hoped that the implementation of the package deal would help overcome the difficulties facing Europe and be conducive to the recovery and growth of the European economy."It is mainly up to Europe to resolve the European debt problem," Hu said."We believe that Europe has all the wisdom and capability to resolve the debt problem," he added.Sarkozy said Europe is committed to resolving the debt crisis by making its own effort and strengthening cooperation with the international community. Hu said China wants to see Europe prosper.Noting that it was the third time for him to meet Sarkozy so far this year, Hu said the two sides had a frank and in-depth exchange of views on bilateral links, world economic situation, G20 affairs and major international issues and reached many important consensuses.The development of China-France relations has maintained good momentum recently. President Hu paid a state visit to France in November last year and met Sarkozy in March and August this year when the French president visited China.Hu said China places importance on developing its relations with France and the EU. He also thanked Sarkozy for France's meticulous preparation for the G20 summit and its hospitality to global leaders.France values China's role and appreciates its focus on major international issues, Sarkozy said, adding that his country is willing to maintain close communication and consultation with China.

BEIJING, Jan. 9 (Xinhua) -- China's official website for booking train tickets received a daily average of more than 1 billion hits during the first week of January, according to a railway official.Hu Yadong, vice minister of railways, said Sunday that the online ticket sales platform has provided consumers with a convenient way to buy tickets. He also addressed complaints about the fairness of the sales process."Train tickets sold online or by telephone have topped 2 million daily, meaning that around one-third of passengers don't have to wait in line at train stations for several hours to get a ticket," Hu said.However, many Chinese have expressed dissatisfaction with the website, with some people unable to get train tickets home for this year's Spring Festival holiday, a major holiday in China.Several customers posted their complaints on popular microblogging website weibo.com, stating that the booking site often failed due to "too many visits at the same time."The Spring Festival holiday is always a difficult time for China's public transportation authorities. A total of 3.16 billion passenger trips are expected during the holiday, up 9.1 percent from a year earlier, of which 235 million trips will be made via the country's railways, up 6.1 percent year-on-year, said Hu.This year's transport rush in the Spring Festival Season started on Sunday and will end on Feb. 16, according to the Ministry of Railways.

WASHINGTON, Jan. 2 (Xinhua) -- A systematic review of previous studies suggests that there may be a positive connection between physical activity and children's academic performance, according to a report published Monday in the Archives of Pediatrics & Adolescent Medicine.A group of scientists at the Vrije Universiteit (Free University) Medical Center in the Netherlands reviewed evidence on the relationship between physical activity and academic performance because of concerns that pressure to improve test scores may often mean more instructional time for classroom subjects with less time for physical activity.The authors identified 10 observational and four interventional studies for review, 12 of which were done in the United States, one in Canada and one in South Africa. Sample sizes ranged from 53 to about 12,000 participants between the ages of eight years and 18 years old. Follow-up varied from eight weeks to more than five years."According to the best-evidence synthesis, we found strong evidence of a significant positive relationship between physical activity and academic performance. The findings of one high-quality intervention study and one high-quality observational study suggest that being more physically active is positively related to improved academic performance in children," the report said.Background information in the article suggests that exercise may help cognition by increasing blood and oxygen flow to the brain, increasing levels of norepinephrine and endorphin to decrease stress and improve mood, and increasing growth factors that help create new nerve cells and support synaptic plasticity."More high-quality studies are needed on the dose-response relationship between physical activity and academic performance and on the explanatory mechanisms, using reliable and valid measurement instruments to assess this relationship accurately," the report concluded.

WASHINGTON, Nov. 24 (Xinhua) -- A new study suggests that the rate of global warming from doubling of atmospheric carbon dioxide may be less than the most dire estimates of some previous studies.Authors of the study, which was funded by the National Science Foundation and published online on Thursday in the journal Science, say that global warming is real and that increases in atmospheric CO2 will have multiple serious impacts. However, the most Draconian projections of temperature increases from the doubling of CO2 are unlikely."Many previous climate sensitivity studies have looked at the past only from 1850 through today, and not fully integrated paleoclimate date, especially on a global scale," said Andreas Schmittner, an Oregon State University researcher and lead author on the Science article. "When you reconstruct sea and land surface temperatures from the peak of the last Ice Age 21,000 years ago -- which is referred to as the Last Glacial Maximum -- and compare it with climate model simulations of that period, you get a much different picture.""If these paleoclimatic constraints apply to the future, as predicted by our model, the results imply less probability of extreme climatic change than previously thought," Schmittner added.Scientists have struggled for years trying to quantify "climate sensitivity" -- which is how the Earth will respond to projected increases of atmospheric carbon dioxide. The 2007 IPCC report estimated that the air near the surface of the Earth would warm on average by two to 4.5 degrees (Celsius) with a doubling of atmospheric CO2 from preindustrial standards. The mean, or " expected value" increase in the IPCC estimates was 3.0 degrees; most climate model studies use the doubling of CO2 as a basic index.The researchers based their study on ice age land and ocean surface temperature obtained by examining ices cores, bore holes, seafloor sediments and other factors. When they first looked at the paleoclimatic data, the researchers only found very small differences in ocean temperatures then compared to now."Our study implies that we still have time to prevent that from happening, if we make a concerted effort to change course soon," said Schmittner.
