HAIFA, Israel, Oct. 5 (Xinhua) -- "It's a big day, a celebration shared by Israel, science and the entire world," Israeli researcher Daniel Shechtman, who won the 2011 Nobel Prize in chemistry, said here at a press conference at the Technion- Israel Institute of Technology.Shechtman, 70, has spent the past five decades at Technion. He is also an associate at the Ames Laboratory of the U.S. Department of Energy and has lectured at universities abroad."Thousands of scientists are currently researching the subject I developed and I'm sure that all of them view the prize as their accomplishment too," he told Xinhua, adding that, "Science (in general) wouldn't be here and be as prosperous and intricate as it is if not for the work of thousands of others around the world."The Swedish Royal Academy of Sciences on Wednesday announced Shechtman as the winner of this year's Nobel chemistry prize for his cutting-edge research on quasicrystals, a type of atom form that for decades was considered impossible by the global scientific community.The award panel explained that Shechtman's work, launched in early 1980s, has revolutionized the perception of solid matter.His work forced crstyallographers to revamp their basic conception that atoms inside crystals only have repeating and symmetrical patterns.Shechtman is the 10th Israeli scientist to win the Nobel Prize and the fourth to win the prize in chemistry.Ada Yonat, a researcher at the Weizmann Institute near Tel Aviv, received the chemistry prize in 2009.The announcement from Stockholm captured headlines in Israel, drawing praise from the country's leadership, who said Shechtman's achievement is a testament to the Jewish state's stature as a technological powerhouse.Israeli Prime Minister Benjamin Netanyahu said the winning of the Nobel Prize "expresses our people's intellect.""Every Israeli citizen is happy today and every Jew in the world is proud," a statement issued by Netanyahu's office quoted him as telling the scientist in a telephone call.Israeli President Shimon Peres, who is also a Nobel laureate, later called to congratulate Shechtman."You demonstrate that a thinking person who is hardworking and brave can make groundbreaking scientific discoveries," he said.

WASHINGTON, Oct. 4 (Xinhua) -- Green tea may slow down weight gain and serve as another tool in the fight against obesity, according to U.S. Pennsylvania State University food scientists.Obese mice that were fed a compound found in green tea along with a high-fat diet gained weight significantly more slowly than a control group of mice that did not receive the green tea supplement, said Joshua Lambert, assistant professor of food science in agricultural sciences."In this experiment, we see the rate of body weight gain slows down," said Lambert.The researchers, who released their findings on Tuesday in the online version of Obesity, fed two groups of mice a high-fat diet. Mice that were fed Epigallocatechin-3-gallate -- EGCG -- a compound found in most green teas, along with a high-fat diet, gained weight 45 percent more slowly than the control group of mice eating the same diet without EGCG.In addition to lower weight gain, the mice fed the green tea supplement showed a nearly 30 percent increase in fecal lipids, suggesting that the EGCG was limiting fat absorption, according to Lambert. The green tea did not appear to suppress appetite. Both groups of mice were fed the same amount of high-fat food and could eat at any time."There seems to be two prongs to this," said Lambert. "First, EGCG reduces the ability to absorb fat and, second, it enhances the ability to use fat."A person would need to drink ten cups of green tea each day to match the amount of EGCG used in the study, according to Lambert. However, he said that recent studies indicate that just drinking a few cups of green tea may help control weight."Human data -- and there's not a lot at this point -- shows that tea drinkers who only consume one or more cups a day will see effects on body weight compared to nonconsumers," said Lambert.

BEIJING, Nov. 24 (Xinhua) -- In response to public suspicion stoked by recent dumpling contamination scandals, China's Ministry of Health on Thursday said the new food safety standard for flash-frozen dumplings did not show signs of leniency.The Ministry introduced the new food safety standard on flash-frozen dough or rice products on Thursday.The Ministry has been accused of loosening scrutiny over a disease-generating bacteria in such foods, staphylococcus aureus, or golden staph, which can cause various diseases, including pneumonia and sepsis, and is sometimes life-threatening.The controversy became particularly relevant after several major brands of frozen dumplings have been successively recalled in recent months.In October, a Henan-based company, Zhengzhou Sinian Food Co., Ltd, confirmed the contamination of golden staph in its flash-frozen seafood- and pork-stuffed dumplings.Frozen dumplings made by Hong Kong-based manufacturer Wanchai Ferry were found to contain golden staph in November, and some of its products have been pulled from shelves.The previous standard provided that no golden staph should be tested in such food, while the new one gives a quantitative restriction that the volume of the bacteria should be no more than ten to the fourth degree.Liu Xiumei, a food safety expert with the Chinese Center for Disease Control and Prevention, said at the press conference held by the health ministry that such bacteria becomes inactivate after the food is boiled for a few seconds, and it takes a volume of ten to the fifth degree to generate toxicity.The previous standard could only serve as a general provision due to the lack of quantitative microbiological testing back when it was introduced, Liu said, stressing that the new standard is not a sign that the Ministry has gone soft on bacterial contamination of relevant foods.The new standard will come into effect starting Dec. 21, 2011.

VIENTIANE, Dec. 5 (Xinhua) -- Laos and China pledged on Monday to deepen military exchanges and cooperation, strengthen unity and friendship between the two countries'militaries and work together to maintain regional peace and stability.The vows came out of the meeting between the Lao Deputy Prime Minister, Minister of National Defense Douangchay Phichith, Lao Deputy Minister of National Defense Sanyahak Phomvihane and the visiting Deputy Chief of General Staff of the Chinese People's Liberation Army (PLA) Cai Yingting.Douangchay said the Lao side appreciates the Chinese side's long-term support and help which have contributed to the Lao social economic development and national defense building. The Lao Party, government and military attach great importance to developing relations with China, and are willing to make joint efforts with the Chinese side to further promote the two states and militaries' ties to a new level.Sanyahak said that no matter how changes in the international and regional situation, the solid traditional friendship between the two countries' people and militaries won't change. Laos is willing to cooperate with China closely, deepen communication and cooperation between the two militaries, and constantly strengthen unity and friendship of the two sides.Cai said that China and Laos are friendly neighbors, the peoples of the two countries have forged a profound friendship since ancient times. In recent years, the bilateral ties continue to see a healthier and stabler development, especially after the two countries have established a comprehensive strategic and cooperative partnership.The Chinese side will continue to maintain close high-level contacts with Laos, enhance substantial cooperation, and strengthen friendly coordination, in order to contribute to the bilateral ties, and regional peace, stability and prosperity, Cai added.The Cai-led Chinese PLA delegation arrived in Lao's capital of Vientiane on Monday at the invitation of the Lao Ministry of National Defense, kicking off their friendly visit to Laos.

BEIJING, Dec. 2 (Xinhua) -- China cannot use its 3.2 trillion U.S. dollars in foreign exchange reserves to rescue other countries, a senior diplomat said on Friday."The argument that China should rescue Europe does not stand, as reserves are not managed that way," Vice Foreign Minister Fu Ying said at the Lanting forum, a gathering of Chinese officials, scholars and social groups held by the Ministry of Foreign Affairs to discuss international issues and foreign policy."China is not absent from international efforts to rescue Europe; it has been a positive and healthy participant," Fu said.Since the outbreak of the European financial crisis, China has dispatched more than 30 procurement delegations to Europe, helping to boost imports from the continent, Fu said.Fu added that there are many misunderstandings about the use of China's foreign reserves. "Foreign reserves are not domestic income or money that can be disposed of by the premier or finance minister," she said."Foreign reserves are akin to savings, and their liquidity should be ensured," Fu said."Foreign reserves are not revenue and cannot be relocated randomly. Under this circumstance, China should take the prospect of yields into consideration if it invests its foreign reserves," said Tian Dewen, an analyst at the Institute of European Studies at the Chinese Academy of Social Sciences.However, the outlook for the economic situation in the eurozone is currently uncertain, Tian said.Fu said China learned a lesson about the importance of foreign reserves during the Asian financial crisis of the late 1990s. ' "Reserves cannot be used domestically to alleviate poverty or taken abroad for development support," she said.She said that the way in which foreign reserves are managed should be in line with the principles of "safety, liquidity and proper profitability.""China's purchases of European bonds, International Monetary Fund bonds and U.S. bonds are also based on those principles," Fu said.Fu also said that China has no intention to gain profit by leveraging financial instruments."China will make efforts to overcome the crisis with Europe and the international community in the future," Fu said."As for the current turbulence in European markets, an authoritative voice is necessary in restoring market confidence. However, voices are diversified in Europe due to its political framework," said Chen Xin, an analyst at the Institute of European Studies at the Chinese Academy of Social Sciences.Fu also reviewed achievements made in trade and investment cooperation between the two sides."It is normal for Europe to strengthen its economic cooperation with China in the process of conquering its difficulties, although it is not proper to add negative political implications," Fu said.She urged Europe not to politicize China's foreign investments."Successful investment should be reciprocal. We hope our economic activities are not interpreted from a political prospective and are not imbued with political interests. We should follow market economy principles," Fu saidFu also took time to single out media reports about the crisis that she believes have been overtly political."Many European countries have shown their understanding and support for us, but there have also been some negative reports," Fu said."We should treat each other with a moderate and impartial mentality. That will make bilateral relations easier to handle," Fu said.She cited an investment bid by a Chinese company in Iceland that was turned down by the country's government.Zhongkun, a private Chinese real estate company founded in 1995, planned to buy 300 square km of land in Iceland to build a high-end resort with a total investment of 200 million U.S. dollars.However, Iceland's Interior Ministry rejected the bid, citing the size of the area of land involved and the fact that there is no precedent in Iceland for foreign countries to purchase large tracts of land.
