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, Nov. 24 (Xinhua) -- An inexpensive drug that treats Type 2 diabetes has been shown to prevent a number of natural and man-made chemicals from stimulating the growth of breast cancer cells, according to a newly published study by a Michigan State University researcher. The research, led by pediatrics professor James Trosko and colleagues from South Korea's Seoul National University, provides biological evidence for previously reported epidemiological surveys that long-term use of the drug metformin for Type 2 diabetes reduces the risk of diabetes-associated cancers, such as breast cancers.The research appeared online this week in PLoS One.For the study, Trosko and colleagues focused on the concept that cancers originate from adult human stem cells and that there are many natural and man-made chemicals that enhance the growth of breast cancer cells. Using culture dishes, they grew miniature human breast tumors, or mammospheres, that activated a certain stem cell gene. Then the mammospheres were exposed to natural estrogen -- a known growth factor and potential breast tumor promoter -- and man-made chemicals that are known to promote tumors or disrupt the endocrine system.The team found that estrogen and the chemicals caused the mammospheres to increase in numbers and size. However, with metformin added, the numbers and size of the mammospheres were dramatically reduced. While each of the chemicals enhanced growth by different means, metformin seemed to be able to inhibit their stimulated growth in all cases."While future studies are needed to understand the exact mechanism by which metformin works to reduce the growth of breast cancers, this study reveals the need to determine if the drug might be used as a preventive drug and for individuals who have no indication of any existing cancers," Trosko said.

WASHINGTON, Dec. 2 (Xinhua) -- The U.S. Justice Department Friday approved Google's 400 million dollar acquisition of Admeld, a company that provides an online advertising platform for publishers.The Justice Department concluded that it was "not likely to substantially lessen competition in the sale of display advertising."Google operates the largest Internet search engine in the world and one of the largest display advertising platforms. It had revenues of about 29 billion dollars in 2010, most of which came from ads revenue.Admeld, with annual revenue of 30 million dollars, offers technology services to Internet publishers that help them boost revenue by optimizing ads display from hundreds of sources.Google is expected to grab 9.3 percent of online display advertising spending in the U.S. this year, up from 8.6 percent last year, making it the No. 3 provider, according to the digital intelligence company Emarketer.The No. 1 position will be taken by Facebook with its share increased to 16 percent up from 12 percent a year ago, while Yahoo! will slip slightly to 13 percent, said Emarketer.

BEIJING, Jan. 23 (Xinhua) -- Nearly 200,000 local residents and tourists visited parks in Beijing on Monday as a series of celebrations were hosted to mark the first day of the Chinese lunar New Year, the city's park administration said.Festive activities kicked off at Beijing's famous parks, including the Temple of Heaven, the Summer Palace, and the Beihai Park, on Monday to welcome the Year of the Dragon, said Chen Zhiqiang, spokesman for the Beijing Municipal Administration Center of Parks.At the Temple of Heaven, 320 costumed performers on Monday staged a show presenting the royal heaven worship ceremony in the Qing Dynasty (1644-1911).In the one-hour ceremony, thousands of visitors watched as the royal parade marched toward the altar where the "emperor" held a ritual to pray for peace and good harvest in the coming year.At the Summer Palace, the ancient royal garden, a traditional fair opened to public with old-fashioned shops and stands selling items and snacks popular in the old days.The Chinese New Year, which begins on Monday this year, is an important occasion for family dinners, fireworks, and a trip to temple fairs.To cope with the increase in visitors, authorities in Beijing said they have deployed seven police choppers and 910,000 order-maintaining personnel across the city to prevent the breakout of fires and stampedes.

SAN FRANCISCO, Jan. 12 (Xinhua) -- Microsoft on Thursday announced a patent licensing agreement with LG Electronics covering the South Korean manufacturer's tablets, smartphones and other consumer devices running Google's Android or Chrome operating system.In a press release, Microsoft said it marks the 11th deal with a device manufacturer leveraging Google's operating system platform, noting that "more than 70 percent of all Android smartphones in the U.S. are now receiving coverage under Microsoft 's patent portfolio."Terms of the deal were not disclosed. So far, Microsoft has struck major cross-licensing patent agreements with HTC, Samsung and Acer, among others.Last September, Microsoft announced a broad patent deal with Samsung. U.S. media reports cited South Korean media as saying that Microsoft had wanted Samsung to pay 10 to 15 U.S. dollars for each Android device.The booming mobile market has been harassed by acrimonious legal battles over patent infringement. Being an open source operating system, Google's Android has become a major target of patent suits.Microsoft has been going after companies that make phones and tablets running Android, rather than directly against Google. But the two tech giants are still engaged in public spats over the issue after Google's top legal officer posted a scathing blog last August accusing Microsoft and other companies of waging "a hostile, organized campaign against Android."Motorola Mobility, which Google announced to acquire in a 12.5 billion-dollar deal last August, currently is the last major Android device vendor that refuses to take a license from Microsoft.Frank Shaw, Microsoft's head of communications, used Twitter to taunt Google on Thursday, twitting "Hey Google -- we are the 70 percent" with a link to their press release.Brad Smith, Microsoft's executive vice president and general counsel, also tweeted "it's time to recognize that in patent world, lawsuits are the 1 percent; license agreements are the 99 percent. "Google so far has made no comments on the Microsoft-LG patent deal.
