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, June 11 (Xinhua) -- The Baidu Charitable Foundation (The Baidu Foundation) and The Bill & Melinda Gates Foundation (The Gates Foundation) founded a strategic charitable alliance here Saturday, in a bid to work for a healthy, smoke-free environment both in China and around the world.Li Yanhong, president of Baidu company, China's top online search engine operator, and Bill Gates, co-chair and trustee of the foundation under the names of the couple, attending the ceremony, both wore a shirt that said, "Say No to Forced Smoking."In his speech at the ceremony, Bill Gates said, "This will be a long-term, open-ended alliance. As a sponsor, Mr. Li and I would like to welcome more partners, and we expect to see more Chinese enterprises and all facets of society to focus on public health issues together."Li Yanhong also addressed the meeting, claiming, "Living healthy and green has become a common pursuit of mankind. We hope the alliance can bring together public efforts for this global cause, so that more people can benefit from our endeavor." ' The alliance's first action is to comply with the government ban on smoking in public places and refuse forced smoking, according to a press release from the foundations.Targeting "forced smokers," the alliance will carry out educational campaign through all channels of media to educate and promote self-awareness about the dangers of forced smoking. Moreover, it will also help existing smokers, especially those who are underage, by sharing scientific methods for quitting.Smoking is one of the world's eight primary causes of death, leading to lung disease, cancer, heart disease, low birth rate, fetal death, tuberculosis, high mortality and many other health issues. Smoking forces many families into poverty by causing both poor health and premature death.China ranks first in tobacco consumption and production in the world. China has 300 million smokers, and one in every three cigarettes smoked in the world is smoked in China. More than half of Chinese smokers are male; and more than 1 million people die from smoking related diseases each year.In addition, China has 740 million "forced smokers," whose health also suffers. The World Health Organization (WHO) notes that there is no safe level of second-hand smoke.This year, China published its 12th Five-Year Plan (2011-2015) that clearly stipulates for "implementing a full-scale ban on smoking in public facilities." This is the first time that tobacco control has been included as part of China's five-year plan for national economic and social development."Rules for Implementation of Public Facilities Health Management Regulations," effective since May 1st, also specifies to "ban smoking at all public indoor facilities," providing legal basis for non-smokers to protect their rights of health and to refuse "involuntary smoking."Aside from tobacco control, the strategic alliance co-founded by the foundations will also collaborate on a series of projects, such as AIDS prevention and control, in a joint effort to promote health for mankind.Founded in 2000, the Gates Foundation currently carries out charity projects in over 100 countries. Since establishing the Beijing Representative Office in 2007, the Gates Foundation has supported a range of health and development projects in China, including the advocacy of smoke-free environment, AIDS and tuberculosis prevention and control, and agricultural development and research projects.Launched in 2010, the Baidu Foundation is committed to use information technology for support of youth and disadvantaged groups, focus on the environment and promote social harmony.Ever since Baidu was founded, Li has actively pushed for tobacco control within the enterprise and the industry. He is the only Chinese member of the United Nation AIDS Prevention Senior Committee and also board member of the HuaXia Charity Foundation.

TAIYUAN, June 18 (Xinhua) -- A Chinese medical university will join hands with the Massey University of New Zealand to set up a community clinic specializing in chronic diseases in north China's Shanxi Province.The community clinic in Taiyuan, the provincial capital city, will provide medical services to more than 7,500 residents in the city's Hanxiguandong community, Ma Qianjin, vice president of the Shanxi University of Traditional Chinese Medicine, said on Friday.Residents will be able to seek advice from both Chinese and New Zealand experts on how to prevent chronic diseases like diabetes, said Ma.The clinic, which is expected to open this year, will also provide residents with free health check-ups and create health records for them.Bruce Ullrich, a Massey University board member, said on Friday that the clinic will integrate Western service with traditional Chinese medical techniques in its prevention and treatment of chronic diseases."The community clinic will mainly focus on people with obesity, diabetes and other chronic diseases. The cost of disease prevention will be dramatically lower than the cost of treatment," said Ullrich.Zhang Xinwei, deputy director of the provincial science and technology bureau, said that if the clinic's practices are successful, the model may be adopted by other regions in China.

WASHINGTON, Aug. 18 (Xinhua) -- Using integrated radar observations from a consortium of international satellites, NASA-funded researchers have created the first complete map of the speed and direction of ice flow in Antarctica, the U.S. National Aeronautics and Space Administration (NASA) announced Thursday.The map, which shows glaciers flowing thousands of miles from the continent's deep interior to its coast, will be critical for tracking future sea-level increases from climate change."This is like seeing a map of all the oceans' currents for the first time. It's a game changer for glaciology," said Eric Rignot of NASA's Jet Propulsion Laboratory and the University of California (UC), Irvine. Rignot is lead author of a paper about the ice flow published online Thursday in Science Express. "We are seeing amazing flows from the heart of the continent that had never been described before."Rignot and UC Irvine scientists used billions of data points captured by European, Japanese and Canadian satellites to weed out cloud cover, solar glare and land features masking the glaciers. With the aid of NASA technology, the team painstakingly pieced together the shape and velocity of glacial formations, including the previously uncharted East Antarctica, which comprises 77 percent of the continent.Like viewing a completed jigsaw puzzle, the scientists were surprised when they stood back and took in the full picture. They discovered a new ridge splitting the 5.4-million-square-mile landmass from east to west.The team also found unnamed formations moving up to 800 feet annually across immense plains sloping toward the Antarctic Ocean and in a different manner than past models of ice migration."The map points out something fundamentally new: that ice moves by slipping along the ground it rests on," said Thomas Wagner, NASA's cryospheric program scientist in Washington. "That's critical knowledge for predicting future sea level rise. It means that if we lose ice at the coasts from the warming ocean, we open the tap to massive amounts of ice in the interior."
