WASHINGTON, Nov. 9 (Xinhua) -- An international team of researchers funded by NASA and the National Science Foundation (NSF) will travel next month to one of Antarctica's most active, remote and harsh spots to determine how changes in the waters circulating under an active ice sheet are causing a glacier to accelerate and drain into the sea, the U.S. space agency announced Wednesday.The science expedition will be the most extensive ever deployed to Pine Island Glacier. It is the area of the ice-covered continent that concerns scientists most because of its potential to cause a rapid rise in sea level. Satellite measurements have shown this area is losing ice and surrounding glaciers are thinning, raising the possibility the ice could flow rapidly out to sea.The multidisciplinary group of 13 scientists, led by Robert Bindschadler, emeritus glaciologist of NASA's Goddard Space Flight Center, will depart from the McMurdo Station in Antarctica in mid- December and spend six weeks on the ice shelf. During their stay, they will use a combination of traditional tools and sophisticated new oceanographic instruments to measure the shape of the cavity underneath the ice shelf and determine how streams of warm ocean water enter it, move toward the very bottom of the glacier and melt its underbelly."The project aims to determine the underlying causes behind why Pine Island Glacier has begun to flow more rapidly and discharge more ice into the ocean," said Scott Borg, director of NSF's Division of Antarctic Sciences, the group that coordinates all U.S. research in Antarctica. "This could have a significant impact on global sea-level rise over the coming century."

VIENNA, Nov. 25 (Xinhua) -- China is to further help the least developed countries (LDCs) in their development effort through zero-tariff treatment and other measures, Yu Jianhua, China's Assistant Commerce Minister said here Friday.Addressing a LDCs Ministerial Meeting in Vienna, Yu said China will focus on six concrete measures to advance the implementation of the Programme of Action (IPoA), adopted by the Fourth United Nations Conference on LDCs in Istanbul in May.First, as announced by Chinese president Hu Jintao during the G20 summit in Cannes, China would, in the context of South-South cooperation, give zero-tariff treatment to 97 percent of the tariff items of exports to China from the LDCs that have diplomatic relations with China.Second, tilt foreign aid further to the LDCs.Third, carry out cooperation in livelihood projects in the LDCs, including hospital, school, domestic water use and clear energy.Fourth, strengthen agricultural cooperation with the LDCs, including the increase of food aid, dispatching agricultural and technical experts.Fifth, strengthen personnel education in the LDCs to build capacity for self-development.Sixth, continuously promote the establishment of economic and trade cooperation zone in the LDCs by Chinese companies.Yu said that debt crisis in some countries, turmoil in financial markets, inflation pressure in emerging countries; extreme weather and recurrent natural disasters have brought enormous harm to the economies of the LDCs.In this situation, the global community should stand united to give more supports to the LDCs, he stressed.For a long time, China has actively supported the LDCs, under the framework of the South-South Cooperation, through economic and technical aids, debt reduction and personnel training and increase of imports from these countries, he said.Meanwhile, Yu praised the unique role of the UN Industrial Development Organization (UNIDO) in implementing the IPoA, helping structural transformation in the LDCs and promoting the sustainable development.He also said that the Chinese government would continue to support the UNIDO and help the LDCs develop their economies in an all-round way.

YICHANG, Oct. 30 (Xinhua) -- China's Three Gorges Dam on Sunday reached its designed highest mark, the second time for the world's largest water control and hydropower project to run at full capacity.The water level hit 175 meters at 5 p.m. after storing water for nearly two months from the water level of 152 meters, said an official with the China Three Gorges Project Corporation (CTGPC), the developer of the project.A dozen hydropower turbo-generator units started operation on Sunday, generating power capacity of 8.2 million kw, said the official.The dam in central China's Hubei Province completed its first full-capacity test last October.Operating at full capacity should give full play to the dam's functions of generating hydroelectric power, delivering water to the lower reaches to alleviate spring droughts, and containing water from summer flooding, as required by the State Flood Control and Drought Relief Headquarters.The Three Gorges Project was launched in 1993 with a budget equivalent to 22.5 billion U.S. dollars.So far, monitoring shows the dam is operating smoothly.

BEIJING, Nov. 17 (Xinhua) -- Chinese State Councilor Liu Yandong on Thursday met with a U.S. artist delegation, vowing to promote bilateral cultural and art exchanges.Headed by President and Chief Executive Officer of the Asia Society Vishakha Desai, the delegation will participate in the China-U.S. Forum on the Arts and Culture from Nov. 16-19 in Beijing.Liu welcomed the U.S. artists, noting cultural and art exchanges are an important component of bilateral people-to-people exchanges.She said the founding of the forum established an institutionalized and constructive platform for deepening bilateral relations and friendship between the two peoples.Artists from the two countries should exert their influence and actively promote bilateral cultural exchanges, she said.The forum is organized by the Chinese People's Association for Friendship with Foreign Countries, the Asia Society and the Aspen Institute.An extraordinary line-up of American cultural icons will attend the event, including actress Meryl Streep, film director Joel Coen, musician Yo-Yo Ma, and best-selling author Amy Tan.

WASHINGTON, Dec. 28 (Xinhua) -- People with diets high in several vitamins or in omega 3 fatty acids are less likely to have the brain shrinkage associated with Alzheimer's disease than people whose diets are not high in those nutrients, according to a new study published on Wednesday in the online issue of Neurology, the medical journal of the American Academy of Neurology.Those with diets high in omega 3 fatty acids and in vitamins C, D, E and the B vitamins also had higher scores on mental thinking tests than people with diets low in those nutrients. These omega 3 fatty acids and vitamin D are primarily found in fish. The B vitamins and antioxidants C and E are primarily found in fruits and vegetables.In another finding, the study showed that people with diets high in trans fats were more likely to have brain shrinkage and lower scores on the thinking and memory tests than people with diets low in trans fats. Trans fats are primarily found in packaged, fast, fried and frozen food, baked goods and margarine spreads.The study involved 104 people with an average age of 87 and very few risk factors for memory and thinking problems. Blood tests were used to determine the levels of various nutrients present in the blood of each participant. All of the participants also took tests of their memory and thinking skills. A total of 42 of the participants had MRI scans to measure their brain volume. Overall, the participants had good nutritional status, but seven percent were deficient in vitamin B12 and 25 percent were deficient in vitamin D.Study author Gene Bowman, of Oregon Health & Science University in Portland, said that the nutrient biomarkers in the blood accounted for a significant amount of the variation in both brain volume and thinking and memory scores. For the thinking and memory scores, the nutrient biomarkers accounted for 17 percent of the variation in the scores. For brain volume, the nutrient biomarkers accounted for 37 percent of the variation."These results need to be confirmed, but obviously it is very exciting to think that people could potentially stop their brains from shrinking and keep them sharp by adjusting their diet," Bowman said.
