SAN FRANCISCO, Oct. 14 (Xinhua) -- Google on Friday announced to shut down the highly-controversial social networking product Google Buzz, along with several other services in the coming weeks.On the company's official blog, Google announced the death penalty to its code search engine, Buzz, Jaiku which let users send updates to friends, the Google personalized homepage feature iGoogle, and the University Research Program for Google Search.The shut-downs came as part of Google's housecleaning effort announced in early September, in which the company said it will shut down a number of products and merging others into existing products as features."Changing the world takes focus on the future, and honesty about the past. We learned a lot from products like Buzz, and are putting that learning to work every day in our vision for products like Google+. Our users expect great things from us; today's announcements let us focus even more on giving them something truly awesome," said Google in the blog post.Google Buzz, a social networking and messaging tool integrated into Gmail service, has been widely criticized for privacy concerns and held back the search giant from expanding its businesses to the social networking space.After Buzz, Google launched Google+ in June, which has been receiving a good response and passed the 40 million user mark, the company's chief executive officer Larry Page said Thursday.

BEIJING, Nov. 25 (Xinhua) -- The Ministry of Commerce (MOC) said Friday that it will start an investigation into the U.S. government's policy support and subsidies for its renewable energy sector over trade barrier concerns.The MOC will look into six renewable energy programs concerning wind, solar and hydroelectric energy in the states of Washington, Massachusetts, Ohio, New Jersey and California, the MOC said in a statement posted on its website.The investigation was applied for by the China Chamber of Commerce for Imports and Exports of Machinery and Electronic Products, as well as the new energy chamber of the All-China Federation of Industry and Commerce."The applicants argued that the U.S. government's policy support and subsidies for its renewable energy industry constitute a trade barrier, as they violate the rules of the World Trade Organization and have hindered and restricted the development of China's renewable energy sector," the statement said.The applicants requested the elimination of any negative influence from the U.S. government's policy support and subsidies in order to maintain a fair trade environment, according to the statement.The investigation will end before May 25, 2012, although it may be extended to August 25, 2012 under special circumstances, according to the statement.

SHANGHAI, Jan. 11 (Xinhua) -- China has allowed the Bank of East Asia (BEA) to issue yuan-denominated bonds in Hong Kong for a second time, about three years after it became the first foreign-invested bank to make a yuan bond issuance, the bank said Wednesday.BEA China Ltd, a wholly-owned subsidiary of the BEA, was given the approval by the National Development and Reform Commission of China to issue yuan bonds in Hong Kong, it said.Details on the amounts and timing of the offerings weren't available. In 2009, in a major landmark, the BEA issued its first yuan bonds in Hong Kong in an aggregate principal amount of 4 billion yuan (630 million U.S. dollars).The BEA was among the first foreign-invested banks to be given the green light to issue yuan-denominated bonds in Hong Kong, a move analysts say will bolster the international influence of the Chinese currency, also known as renminbi.Sun Minjie, deputy head of BEA China, said the second bond issuance will give the bank stable access to capital, improve its debt portfolio, and support its development on the Chinese mainland.

BEIJING, Oct. 12(Xinhuanet) -- People allergic to peanuts may find relief in a new research by American scientists, according to Huffington Post Monday.Scientists from the Northwestern University Feinberg School of Medicine have found a way to turn off allergic responses by creating an immune system tolerant to peanuts.They attached peanut proteins, the source of the allergy, to white blood cells of mice. Then the mice's immune systems would recognise the proteins and become tolerant to them.When people eat peanuts, allergic human bodies would recognize peanut proteins as invading pathogens and trigger immune responses like throat swelling, even closing up, which can be lethal. Ditto for mice's bodies.But when peanut protein attached to the body's own cells, the immune systems would regard the peanut proteins as perfectly normal and not attack the cells, said Paul Bryce, an assistant professor involved in the study. Then the allergic responses disappeared.The research was conducted on mice. But the scientists expected the method to cure peanut allergies could apply to humans, according to Huffington Post.Although the research was promising, it did not mean that peanut allergies in humans could be actually cured in the foreseeable future, said Dr. Clifford Basset medical director at Allergy and Asthma Care of New York, to ABC News, "Its all about education, prevention and preparedness".

WASHINGTON, Oct. 9 (Xinhua) -- U.S. researchers have found a way to block, in an animal model, the damaging inflammation that contributes to many disease conditions. In their report receiving early online publication Sunday in Nature Biotechnology, researchers describe using small interfering RNA technology to silence the biochemical signals that attract a particular group of inflammatory cells to areas of tissue damage."The white blood cells known as monocytes play a critical role in the early stages of the immune response," says Matthias Nahrendorf, of the Massachusetts General Hospital (MGH) Center for Systems Biology, the paper's senior author. "We now know there are two subsets of monocytes -- an inflammatory subset that defends against pathogens and a reparative subset that supports healing. But if the inflammatory response is excessive, it can block the healing process and exacerbate conditions such as heart disease and cancer."Cells damaged by injury or disease release a cocktail of chemicals called cytokines that attract immune cells to the site of the damage. Inflammatory monocytes are guided to sites of tissue injury by a receptor protein called CCR2, and the MGH-led team devised a strategy targeting that molecule to block the inflammatory process but not the action of the reparative monocytes.Small interfering RNA (siRNA) technology prevents production of specific proteins by binding to associated messenger RNA molecules and preventing their translation. However, the technique requires extreme precision in developing the right siRNA molecule and delivering it to the correct cellular location.To make sure that their siRNA preparation targeted the right monocytes, researchers first confirmed that its use reduced levels of CCR2 in monocytes and increased levels of the fragments produced when siRNA binds to its target. They then showed that monocytes from mice treated with the siRNA preparation were unable to migrate towards CCR2's usual molecular target. Experiments in animal models of several important diseases showed that the siRNA preparation reduced the amount of cardiac muscle damaged by a heart attack, reduced the size and the number of inflammatory cells in atherosclerotic plaques and in lymphomas, and improved the survival of transplanted pancreatic islets."These inflammatory monocytes are involved in almost every major disease," Nahrendorf explains. "Anti-inflammatory drugs currently on the market hit every inflammatory cell in the body, which can produce unwanted side effects. This new siRNA treatment doesn't affect inflammatory cells that don't rely on the CCR2 receptor. That makes a big difference."
