WASHINGTON, April 25 (Xinhua) -- The U.S. National Aeronautics and Space Administration (NASA) and the U.S. Agency for International Development (USAID) have agreed to expand their joint efforts to overcome international development challenges such as food security, climate change, and energy and environmental management.NASA Administrator Charles Bolden and USAID Administrator Rajiv Shah signed a five-year memorandum of understanding on Monday, at NASA Headquarters. The agreement formalizes ongoing agency collaborations that use Earth science data to address developmental challenges, and to assist in disaster mitigation and humanitarian responses. The agreement also encourages NASA and USAID to apply geospatial technologies to solve development challenges affecting the United States and developing countries."Technologies for NASA missions have long improved life here on Earth. Together with USAID, we'll meet even more sustainable development challenges here on the ground, solving problems for the world community," Bolden said in a statement. "As we explore space, we'll also be exploring solutions to important health, nutritional and safety challenges in developing countries."The agencies will continue collaborations to stimulate innovative science and technology solutions to international development challenges by using Earth science data, research results, computer models, visualization applications and remote- sensing techniques.USAID is the lead federal development agency implementing U.S. development efforts through field-based programs and projects around the world. NASA has broad experience with Earth science research, development of Earth science information products, and technology applications."Through our partnership with NASA, we can apply the latest, cutting-edge technology to deliver meaningful results for people in developing countries in areas like health, food security and water," Shah said. "It's a prime example of our efforts to use the power of science and technology to tackle today's pressing development challenges."Since 2003, NASA and USAID have worked together building and expanding the SERVIR program, which allows people in developing regions to use Earth observations for addressing challenges in agriculture, biodiversity conservation, climate change, disaster response, weather forecasting, and energy and health issues.The agencies also collaborate on the LAUNCH program, which supports science and technology innovators in the nonprofit and private sectors. The program's goal is improving innovations to achieve greater impact on sustainability issues.

NEW YORK, May 27 (Xinhua) -- U.S. stocks expanded gains on Friday ahead of the long Memorial Day weekend as surging commodity prices overcame disappointing economic data.European Central Bank Governing Council member George Provopoulos said that Greece might deal with its debt problem if it sticks to the aid program. That comment, which was considered as bullish by investors, drove the U.S. dollar weaker and led commodity prices surge on Friday.The stock market was driven by higher commodities prices, with thin trading volume ahead of the Memorial Day holiday, despite somewhat disappointing economic data on Friday.The Commerce Department said that both personal income and spending rose 0.4 percent in April, in line with market estimates. However, the rise in spending was the smallest in three months, suggesting the consumption situation was still weak.Meanwhile, pending home sales dropped 11.6 percent in April. The reading was a seven-month low. The market expectation was a drop of 1 percent.Moreover, the Thomson Reuters/University of Michigan Consumer Sentiment index came in above analysts' estimates. Concerns about higher gas prices and inflation had knocked the gauge down in March and April.Despite those disappointing data, analysts still held a bullish view toward the stock market. "Despite our near-term caution, we continue to see the S&P 500 reaching 1400 over the coming year," Alec Young, equity strategist of S&P Equity Research told Xinhua.According to Alex, while recent macro headwinds were raising questions about the sustainability of recent earnings momentum, he still believed that a downside trend of market was fairly limited and that the current weakness is more likely to be a correction, rather than the beginning of a new bear market."In our view, 2011 estimated EPS would have to be excessively optimistic to justify a bear market,"he added.The Dow Jones industrial average added 38.82 points, or 0.31 percent, to 12,441.58. The Standard & Poor's 500 was up 5.41 points, or 0.41 percent, to 1,331.10. The Nasdaq Composite Index rose 13.94 points, or 0.50 percent, to 2,796.86.

BEIJING, Jan. 26 (Xinhua) -- Chinese Premier Wen Jiabao Wednesday invited more foreign talents to continue their careers or start businesses in China, pledging better conditions for them.During a seminar with more than 20 veteran foreign experts at the Great Hall of the People a week before the Chinese New Year, Wen thanked the foreign friends for their contributions to China's achievements in 2010.Wen said 2011 is a new starting point for China's modernization, as the country implements its 12th five-year plan for economic and social development."China's development is much more associated with the world and the supply of talents than before," Wen said, adding that China will adopt a more open policy to attract overseas experts.Last year, foreign experts made more than 300,000 visits to China, according to Ji Yunshi, general director of the State Administration of Foreign Experts Affairs.

BEIJING, May 4 (Xinhuanet) -- Children with autism have slightly bigger brains than children without the condition, a study suggests.The research published in the May issue of Archives of General Psychiatry noted the difference in the brain size appears related to increased rates of brain growth before age 2.The researchers from the University of North Carolina also pointed out that though the enlargement continues, the increased growth does not.In 2005, the researchers studied a group of 2-year-old children, and found out the ones with autism had brains that were 5% to 10% larger than children without it.Now the researchers assessed the same group of children at age 5, the psychiatrists re-scanned the brains of 38 children with autism and 21 without the condition. The autistic children still had slightly larger brains, but they had grown at the same rate as the comparison group.This finding could lead to a better understanding of the genes that drive autism, which, in turn, could lead to earlier identification and treatment of the disorder, said study researcher Joseph Piven, MD, according to media report.

CANBERRA, March 23 (Xinhua) -- Up to 45 native species in Western Australia's Kimberley region will die out within 20 years if no action is taken, latest study showed on Wednesday.The Priority Threat Management to Protect Kimberley Wildlife report, released by Commonwealth Scientific and Industrial Research Organization (CSIRO) on Wednesday, was commissioned by the Wilderness Society.The report showed that at present, 20.2 million U.S. dollars a year is spent on conservation efforts in the Kimberley, which is home to an assortment of threatened species.However, the report said even if that money was spent properly, the region would still lose some 31 native animals.The numbers of many more birds, reptiles and mammals, such as the Spotted Tree Monitor and the Western Chestnut Mouse, would dwindle.It called for an immediate cash injection of 96 million U.S. dollars to save creatures like the Golden Bandicoot, the Scaly- Tailed Possum and the Monjon Rock Wallaby from extinction.It will follow by an ongoing investment of 40.43 million U.S. dollars annually in the Kimberley to protect its species, as well as boost plant life, help the climate and conserve indigenous land."This investment is great value," one of the report's six co- authors Hugh Possingham said in a statement released on Wednesday."We can save some of Australia's most iconic mammals and birds at a cost of only about one million U.S. dollars per species per year."
