BEIJING/CHONGQING, Oct. 16 (Xinhua) -- A team of Chinese and American scientists have discovered the world's only evidence of co-existing human beings and dinosaur tracks in a remote county in southwest China's Chongqing Municipality, according to a paper published Saturday in the Geological Bulletin of China, a Chinese core academic journal.Qijiang County's Lianhua Baozhai, which means "Lotus Mountain Fortress" in Chinese, has a large number of dinosaur tracks as well as a well-preserved fortress and historical epigraph, forming a direct line of evidence that ancient Chinese people built a residence and lived there for a long time, said Xing Lida, one of three researchers with the project as well as a doctoral degree candidate with the Department of Biological Sciences of the University of Alberta in Canada.Chinese people could have lived here for more than 700 years, and the mud cracks, ripple marks and duck-billed dinosaur tracks were considered by them to be lotus leaf veins, water environment and lotus, respectively, which is why they named it the Lotus Mountain Fortress, Xing Lida told Xinhua."Research shows that dinosaur tracks impacted ancient Chinese place names and folklore, so place names and folklore can be major clues for us in tracing dinosaur tracks," Xing said.According to the paper, the Lotus Mountain Fortress dinosaur tracks, the largest track group of cretaceous dinosaurs in southwestern China, contains 350 to 400 footprints that had been preserved in many ways, including concave footprints, convex footprints and multilayered footprints.

WASHINGTON, Dec. 5 (Xinhua) -- Young women may reduce their risk of developing cardiovascular disease simply by eating more fish rich in omega-3 fatty acids, researchers reported Monday in Hypertension: Journal of the American Heart Association.In the first population-based study in Danish women of childbearing age, those who rarely or never ate fish had 50 percent more cardiovascular problems over eight years than those who ate fish regularly. Compared to women who ate fish high in omega-3 weekly, the risk was 90 percent higher for those who rarely or never ate fish.About 49,000 women, 15-49 years old, median age of just under 30 years in early pregnancy -- were interviewed by telephone or answered food frequency questionnaires about how much, what types and how often they ate fish, as well as lifestyle and family history questions.Researchers recorded 577 cardiovascular events during the eight- year period, including five cardiovascular deaths in women without any prior diagnosis of the disease. In all, 328 events were due to hypertensive disease, 146 from cerebrovascular disease, and 103 from ischemic heart disease. Inpatient and outpatient admission for cardiovascular disease was much more common among women who reported eating little or no fish. In three different assessments over a 30-week period, women who never ate fish had a three-fold higher disease risk compared to women who ate fish every week."To our knowledge this is the first study of this size to focus exclusively on women of childbearing age," said Marin Strom, lead researcher and post doctoral fellow at the Center for Fetal Programming, at Statens Serum Institute in Copenhagen, Denmark. " We saw a strong association with cardiovascular disease in the women who were still in their late 30's."Fish oil contains long chain omega-3 polyunsaturated fatty acids, which are believed to protect against heart and vascular disease. Few women in the study took fish oil supplements, so these were excluded from the analyses and the results were based on the dietary intake of omega-3 fatty acids, not intake from supplements.The most common fish consumed by women in the study were cod, salmon, herring, and mackerel."Our study shows that for younger women, eating fish is very important for overall health, and even though we found cardio- protective effects at relatively modest dietary levels, higher levels may yield additional benefits," Strom said.

RIYADH, Jan. 15 (Xinhua) -- Visiting Chinese Premier Wen Jiabao and Saudi Arabia's King and Prime Minister Abdullah bin Abdul-Aziz agreed on Sunday to make concerted efforts to enhance bilateral relations under a strategic framework.In their meeting, Premier Wen said Saudi Arabia is a major country in the Arab and Islamic world, which plays a significant role in regional and international affairs.He said China respects Saudi Arabia's political system, development mode as well as its culture and traditions, and is grateful for Saudi Arabia's understanding of and support for China regarding the latter's core interests and major concerns.As the world is undergoing profound changes, China is willing to strengthen coordination with Saudi Arabia on major issues, develop an all-around cooperative partnership in the energy sector, expand cooperation in trade, investment, infrastructure, high-tech, finance, security and law enforcement, so as to enrich the contents of the bilateral relations, he added.King Abdullah said that the government and people of Saudi Arabia cherish friendly feelings for China, and that he believes the strengthening of bilateral cooperation will benefit peoples of both countries.The Saudi king proposed setting up a Saudi Arabia-China high level committee to supervise the two countries' cooperation in the political, economic, cultural and security sectors. Premier Wen agreed with this proposal.On the situation in West Asia and North Africa, the visiting Chinese premier said China respect the choice of the peoples in those countries, understand and support their appeal for reforms, and back the role of regional bodies like the Arab League in maintaining stability.For his part, King Abdullah noted it was the objective of Saudi Arabia's foreign policy to maintain regional peace and stability. Saudi Arabia and China enjoy a high level of mutual trust and share similar views on many issues, he said, adding that the Saudi side wishes to step up consultation and coordination with China.Premier Wen has also met with top Saudi leaders, Secretary General of the Organization of Islamic Cooperation Ekmeleddin Ihsanoglu, and Secretary General of the Gulf Cooperation Council Abdullatif al-Zayani.In a joint statement, the two sides hailed Premier Wen's visit to Saudi Arabia as a complete success, which will contribute to their long-term friendly cooperative relations.The statement said both countries were satisfied with the progress made in bilateral cooperation, and pledged to further enhance relations within the framework of strategic relationship, so as to benefit the two peoples and contribute to regional and world peace, stability and development.The two countries agreed in the document to conduct more high-level exchanges of visits, and to expand trade, investment and cooperation in a wide range of areas. The Saudi side also reiterated its adherence to the one-China policy.Wen arrived in Saudi Arabia Saturday evening after an official visit to Nepal.After his stay in Saudi Arabia, the Chinese leader will continue his visit to the United Arab Emirates and Qatar.

ting fuel and benefits to agriculture from extended growing seasons."Global mitigation leading to a low climate change future reduces costs to Canada in the long term. This reinforces the argument that Canada would benefit environmentally and economically from a post 2012 international climate arrangement that systematically reduced emissions from all emitters - including Canada - over time," the report says.It recommends cooperation between governments, scientists and businesses to find ways to mitigate climate change and adapt to it.Canada's Minister of the Environment Peter Kent said the government has a plan to deal with global warming issues, which will be announced next month."Our government has a plan, a very good plan, to meet our target of reducing greenhouse gases by 17 percent from 2005 base levels, by 2020," Kent told Canada's House of Commons Thursday afternoon."We are moving forward to reduce greenhouse gases and, at the same time, we are investing in programs to help Canadians adapt to climate change," Kent said."Today's report merely echoes what our government has long recognized; that is, the importance of adaptation to climate change," he added.Earlier this week, several hundred people protested the government's policy of exploiting the oil sands deposits in western Canada.Environmentalists have criticized the Canadian government for not working hard enough to reduce CO2 emissions. Last year, a coalition of global warming activists gave Canada the "Fossil of the Year" award for failing to implement the Copenhagen Accord.

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.
