BEIJING, Jan. 26 (Xinhua) -- The Chinese government Wednesday raised the minimum down payment requirement for the purchase of second home to 60 percent of the property's value from 50 percent, to curb property market speculation.The decision was announced in a statement released after an executive meeting of the State Council, China's cabinet, which was presided over by Premier Wen Jiabao.File photo taken on Nov. 14, 2010 shows a newly built residential community in east China's Shanghai Municipality.

BEIJING, May 24 (Xinhuanet) -- Scientists revealed for the first time the molecular structure of proteins, which enables bacteria to transfer electrical charges, according to a new study. The revelation was published in Proceedings of the National Academy of Sciences in the U.S. on Monday.Scientists used a technique called "x-ray crystallography" to reveal the molecular structure of proteins, which work as atom-sized "wires" discharging excess electricity."This is an exciting advance in our understanding of how some bacterial species move electrons from the inside to the outside of a cell," said lead author Tom Clarke of the University of East Anglia's School of Biological Sciences in Norwich, England.He said this discovery means "We can now start developing efficient 'bio-batteries' as the viable energy source in the future."Still, it could take perhaps a decade to go. Before that, existing uses of such bacteria needed to become 100 or 1,000 times more efficient, he said.The advance could also hasten the development of microbe technology that can help clean up oil or uranium pollution, he said.Microbes might in future be enlisted to clean up nuclear accidents such as Japan's Fukushima Daiichi disaster, he added.

BEIJING, May 22 (Xinhua) -- Chinese Premier Wen Jiabao's just concluded trip to Japan, during which he attended the fourth China-Japan-South Korea summit, has significantly boosted tripartite cooperation and regional peace and stability, Chinese Foreign Minister Yang Jiechi said Sunday.Yang, who accompanied Wen during his visit on Saturday and Sunday, told reporters that the two-day trip has further boosted cooperation in East Asia, consolidated popular support for China-Japan friendship, enriched the contents of China-Japan and China-South Korea partnerships, and is of great and profound significance for maintaining regional peace, stability and prosperity.Yang said the trip was practical, effective, productive and a complete success.DEEPENING TRILATERAL COOPERATIONThe trip has deepened trilateral practical cooperation in various fields, Yang said.Wen, at the trilateral summit held in Tokyo on Sunday and attended by Japanese Prime Minister Naoto Kan and South Korean President Lee Myung-bak, put forward a seven-point proposal for the three countries to widen cooperation.First, efforts should be made to support Japan's post-quake reconstruction.Second, the three countries should attach great importance to nuclear safety and strictly implement the consensus reached.Third, the three countries should promote practical cooperation on disaster prevention and reduction.Fourth, they should promote liberalization and facilitation of trade and investment among them, push forward integration of regional economy, and try to start negotiations on a tripartite free trade zone next year.Fifth, they should vigorously develop renewable energy and popularize energy-saving technology.Sixth, they should speed up construction of demonstration bases for circular economy in order to promote rational use of resources, protect the environment and realize sustainable development.Seventh, they should boost people-to-people and cultural exchanges.Premier Wen's proposal was applauded by Japanese Prime Minister Kan and South Korean President Lee.The three leaders, in a joint declaration issued after the summit, said they would deepen the future-oriented comprehensive cooperative partnership among the three countries.They also agreed to cooperate on disaster management, nuclear safety, economic growth, sustainable development and cultural affairs.

BEIJING, Feb. 23 (Xinhua) -- The Chinese People's Political Consultative Conference (CPPCC), China's top political advisory body, opened its door to 43 correspondents from 33 overseas media outlets on Wednesday, 10 days ahead of its upcoming annual session.It was the first time that the top political advisory body invited a group of overseas journalists, including those from Hong Kong, Macao and Taiwan, to tour its work place, which used to be the site of an imperial compound 100 years ago.The media tour was hailed by Zhao Qizheng, head of the CPPCC's Committee of Foreign Affairs, as a move that reflects the "enhanced openness" of the CPPCC.During the tour, resident reporters from countries and regions such as the United States, Russia, Germany and Japan visited the CPPCC auditorium and a gallery that exhibits the agency's history and its role in Chinese political life through numerous pictures and relics.Located in downtown Beijing, the CPPCC was established on September 21, 1949. It is a patriotic united front organization for Chinese people and serves as a key mechanism for multi-party cooperation and political consultation under the leadership of the Communist Party of China (CPC).The main functions of the CPPCC are to conduct political consultations, exercise democratic supervision and participate in the discussion and the handling of state affairs. Reporters raised many questions during the visit.Watanabe Yasuhito, a staff correspondent for the Kyodo News China General Bureau, has been working in China for four years. "As Japan doesn't have similar institutions like the CPPCC, the Japanese generally have little idea of it," he said. "I now have a more direct idea of the system by actually walking into the CPPCC."He told Xinhua that Kyodo News would send eight reporters to the upcoming two annual sessions of China's National People's Congress (NPC), its national legislature and the CPPCC, as many Japanese pay close attention to the major political events in China.He said the 12th Five-Year Program and hot economic issues are among their key concerns. At a one-hour seminar held during the tour, five reporters put forward nearly 10 questions to Zhao Qizheng.Ananth Krishnan, the China correspondent of the Hindu, India's national newspaper, has covered the "two sessions" several times. "I think the next five year plan will be one of the most important issues," he said."We will be interested to see whether there are any new policies in terms of China addressing environmental challenges," he said.He added that he focused on China's reform for the household registration system at the sessions last year so that he could see how China addressed the gap between urban and rural areas."There are similar developmental challenges between India and China since we are both large developing countries with more poverty in rural populations. So we are interested to see how China is addressing the challenges," he said.With the application still going on, overseas reporters who are to cover this year's annual CPPCC session are expected to exceed 1,100, similar to the figure last year, said Zhang Jing'an, head of the Bureau of News Service of the CPPCC's National Committee.Zhang said that besides the three news conferences in the Great Hall of People, five press conferences are devoted to issues such as China's urbanization, scientific innovation, culture and education. Conferences will also be arranged in the news center following annual sessions.Also, the number of panel discussions that were open to the media increased from more than 30 in 2007 to 122 in 2010, Zhang said.Zhao Qizheng told overseas reporters that "the CPPCC will continue to enhance openness during the upcoming session and welcome reporters from both here and abroad to cover the session."China's two annual sessions, the fourth session of the National Committee of the 11th CPPCC and the fourth session of the 11th NPC, will open on March 3 and March 5, respectively.

WASHINGTON, April 3 (Xinhua) -- In the largest study of its kind, researchers from a consortium led by the University of Pennsylvania School of Medicine, the University of Miami, and the Boston University School of Medicine, identified four new genes linked to Alzheimer's disease. The findings appeared Sunday in the current issue of Nature Genetics.Each gene individually adds to the risk of having this common form of dementia later in life. These new genes offer a portal into what causes Alzheimer's disease and is a major advance in the field.The study, conducted by the Alzheimer's Disease Genetics Consortium, reports genetic analysis of more than 11,000 people with Alzheimer's disease and a nearly equal number of elderly people who have no symptoms of dementia. Three other consortia contributed confirming data from additional people, bringing the total number of people analyzed to over 54,000. The consortium also contributed to the identification of a fifth gene reported by other groups of investigators from the United States, the United Kingdom, France, and other European countries.The study is the result of a large collaborative effort with investigators from 44 universities and research institutions in the United States, led by Gerard Schellenberg at University of Pennsylvania."This is the culmination of years of work on Alzheimer's disease by a large number of scientists, yet it is just the beginning in defining how genes influence memory and intellectual function as we age. We are all tremendously excited by our progress so far, but much remains to be done, both in understanding the genetics and in defining how these genes influence the disease process," Schellenberg said.Until recently, only four genes associated with late-onset Alzheimer's have been confirmed, with the gene for apolipoprotein E-e4, APOE-e4, having the largest effect on risk. The Nature Genetics studies add another four -- MS4A, CD2AP, CD33, and EPHA1 -- and contribute to identifying and confirming two other genes, BIN1 and ABCA7, thereby doubling the number of genes known to contribute Alzheimer's disease.
