XI'AN, Sept. 18 (Xinhua) -- At least 12 people were killed and 22 others missing over the weekend in rain-triggered landslides in northwestern Shaanxi Province, local officials said.As of 5:30 p.m. Sunday, rescuers had retrieved 10 bodies from beneath the rocks and mud in Baqiao District of the provincial capital of Xi'an, while another five were injured, said Zhu Zhisheng, vice mayor of Xi'an, who was at the site.Another 22 people remained missing, Zhu said, adding the injured were hospitalized and in stable condition.The landslide around 2 p.m. Saturday unleashed about 100,000 cubic meters of rock and mud down the mountain, engulfing a brick factory and destroying part of a nearby ceramics factory in the suburban district of Xi'an.Rescuers found four bodies on Saturday night and six others were retrieved on Sunday.More than 700 police, firefighters and local residents joined the rescue which went on Sunday night.However, the rescue was hampered by three ensuing slides between 10 a.m. and 11 a.m. Sunday as heavy rains continued slashing the city.About 10,000 cubic meters of newly-triggered rock and mud roared down to the site, forcing rescuers to suspend searching temporarily.Heavy downpours in the province also caused havoc in other areas.A heavy rainfall on Saturday night triggered a landslide that buried a residential house in the suburban district of Jintai in Baoji City, some 175 km to the west of Xi'an.Two people were dug out but later died after they were rushed to a nearby hospital, the municipal government of Baoji said in a statement Sunday.The downpours also brought a landslide in the same district early Sunday morning. Three people were saved and sent to a local hospital, according to the statement.The three wounded were in stable condition, doctors at the hospital said.

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. 

LOS ANGELES, June 23 (Xinhua) -- The sun and its inner planets may have formed differently than previously thought, NASA's Jet Propulsion Laboratory (JPL) said on Thursday.Data revealed differences between the sun and planets in oxygen and nitrogen, which are two of the most abundant elements in our solar system, said JPL in Pasadena, Los Angeles.Although the difference is slight, the implications could help determine how our solar system evolved, JPL said.NASA researchers drew the conclusion after analyzing samples returned by NASA's 2004 Genesis mission, according to JPL.The air on Earth contains three different kinds of oxygen atoms which are differentiated by the number of neutrons they contain. Nearly 100 percent of oxygen atoms in the solar system are composed of O-16, but there are also tiny amounts of more exotic oxygen isotopes called O-17 and O-18. Researchers studying the oxygen of Genesis samples found that the percentage of O-16 in the sun is slightly higher than on Earth or on other terrestrial planets. The other isotopes' percentages were slightly lower."We found that Earth, the moon, as well as Martian and other meteorites which are samples of asteroids, have a lower concentration of the O-16 than does the sun," said Kevin McKeegan, a Genesis co-investigator from University of California, Los Angeles (UCLA) and the lead author of one of two papers published this week in Science journal. "The implication is that we did not form out of the same solar nebula materials that created the sun -- just how and why remains to be discovered." Another paper detailed differences between the sun and planets in the element nitrogen. Like oxygen, nitrogen has one isotope, N- 14, that makes up nearly 100 percent of the atoms in the solar system, but there is also a tiny amount of N-15. Researchers studying the same samples saw that when compared to Earth's atmosphere, nitrogen in the sun and Jupiter has slightly more N-14, but 40 percent less N-15. Both the sun and Jupiter appear to have the same nitrogen composition. As is the case for oxygen, Earth and the rest of the inner solar system are very different in nitrogen."These findings show that all solar system objects including the terrestrial planets, meteorites and comets are anomalous compared to the initial composition of the nebula from which the solar system formed," said Bernard Marty, a Genesis co- investigator from Petrographic and Geochemical Research Center in Fracne and the lead author of the other new Science paper. " Understanding the cause of such a heterogeneity will impact our view on the formation of the solar system."Data were obtained from analysis of samples Genesis collected from the solar wind, or material ejected from the outer portion of the sun. This material can be thought of as a fossil of our nebula because the preponderance of scientific evidence suggests that the outer layer of our sun has not changed measurably for billions of years."The sun houses more than 99 percent of the material currently in our solar system, so it's a good idea to get to know it better, " said Genesis Principal Investigator Don Burnett of the California Institute of Technology, Pasadena, California. "While it was more challenging than expected, we have answered some important questions, and like all successful missions, generated plenty more."Genesis was launched in August 2000. The spacecraft traveled to Earth's L1 Lagrange Point about one million miles from Earth, where it remained for 886 days between 2001 and 2004, passively collecting solar-wind samples.JPL managed the Genesis mission for NASA's Science Mission Directorate, Washington. The Genesis mission was part of the Discovery Program managed at NASA's Marshall Space Flight Center in Huntsville, Alasca.

BEIJING, Sept. 11 (Xinhua) -- Despite a series of disasters, Chinese people tend to believe that the moon is still round and bright in the Mid-autumn Festival.Falling on Monday, the 15th day of the eighth month in the Chinese calendar, it is an important Chinese holiday, next only to the Spring Festival, and a chance for family reunion under the full moon, a symbol for happiness and prosperity.A staff worker shows newly-cooked moon cakes during a Mid-autumn festival celebration activity held in Tianjin, north China, Sept. 11, 2011. Some 100 children from Tianjin and southeast China's Taiwan attended the activity on Sunday.FAMILY REUNIONIn the railway station of Nanjing, capital city of east China's Jiangsu Province, passengers lined in long queues while waiting for their trains on Saturday.Although the three-day holiday seemed too short for a long trip, Xiao Liang carried several bags with him. "I bought wine for my dad, boiled salted duck for my mom, and health products for my grand parents," the young man beamed.In the southwestern Guangxi Zhuang Autonomous Region, Li Yukun didn't believe that she could reunite with her son for holiday. In fact, she never thought she could see the three-year-old boy again.Two years ago, Xiao Wei (pseudonym) from the Dalun village of the Beiliu city was kidnapped. His parents were desperate. "On special occasions like the Mid-autumn Festival, we shed tears while missing him," Li said.Police finally managed to get clues that a similar boy was adopted in the neighboring Guangdong Province.Li prepared for a feast with policemen to celebrate reunion with Xiao Wei.Since a campaign was launched to rescue trafficked children in Guangxi in 2009, 339 children were saved, half of whom had been sent back and could reunite with their parents in this festival.In Sichuan, 10 prisoners with good records in jail were given an opportunity to go back home for the holiday."In the past I could only receive greetings from my relatives behind the bars," a woman surnamed Chen said. "This year, my dream for home finally came true."Meanwhile, 171 prisoners had their jail terms shortened so that they could be released before the Mid-autumn Festival.

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.
