SAN FRANCISCO, Aug. 15 (Xinhua) --- Google Inc. on Monday announced that it has agreed to buy Motorola Mobility Holdings Inc. for about 12. 5 billion U.S. dollars, the largest purchase for the Internet search giant that will allow it to compete more directly with other mobile phone makers.Google said that it will acquire Motorola Mobility for 40 dollars per share in cash, or a total of about 12.5 billion dollars, a premium of 63 percent to the closing price of Motorola Mobility shares last Friday.The transaction was unanimously approved by the boards of directors of both companies and is expected to close by the end of 2011 or early 2012, subject to regulatory approvals and other closing conditions.Google noted that the acquisition of Motorola Mobility, a dedicated partner of its Android mobile operating system, will enhance competition in mobile computing.Motorola Mobility will remain a licensee of Android and Android will remain open, Google said, adding that it will run Motorola Mobility as a separate business."Motorola Mobility's total commitment to Android has created a natural fit for our two companies. Together, we will create amazing user experiences that supercharge the entire Android ecosystem for the benefit of consumers, partners and developers," Larry Page, Google's chief executive officer (CEO), said in a statement."We have shared a productive partnership with Google to advance the Android platform, and now through this combination we will be able to do even more to innovate and deliver outstanding mobility solutions across our mobile devices and home businesses," said Sanjay Jha, CEO of Motorola Mobility.

BEIJING, July 5 (Xinhuanet) -- A new study showed that environmental factors may play a larger role in the development of autism than previously recognized, according to media reports on Tuesday.The new study in the Archives of General Psychiatry looked at 192 pairs of twins in California. It found autism was surprisingly common in fraternal twins, despite the fact that they don’t share as many of the same genes as identical twins, suggesting that something in their mutual life circumstances may be playing at least as strong a role as genetics.The study, which will likely be followed up with similar studies of twins and other siblings, could  force a dramatic swing in the focus of research into the developmental disorder.“It looks like some shared environmental factors play a role in autism, and the study really points toward factors that are early in life that affect the development of the child,” said study researcher Joachim Hallmayer, MD, an associate professor of psychiatry at Stanford University in California.

WASHINGTON, Sept. 14 (Xinhua) -- Controlling diabetes may someday involve mining stem cells from the lining of the uterus, Yale School of Medicine researchers report in a new study published Wednesday in the journal Molecular Therapy. The team treated diabetes in mice by converting cells from the uterine lining into insulin-producing cells.The endometrium or uterine lining, is a source of adult stem cells. These cells generate uterine tissue each month as part of the menstrual cycle. Like other stem cells, however, they can divide to form other kinds of cells.Led by Yale Professor Hugh Taylor, the researchers bathed endometrial stem cells in cultures containing special nutrients and growth factors. Responding to these substances, the endometrial stem cells adopted the characteristics of beta cells in the pancreas that produce insulin. Over the course of a three- week incubation process, the endometrial stem cells took on the shape of beta cells and began to make proteins typically made by beta cells. Some of these cells also produced insulin.After a meal, the body breaks food down into components like the sugar glucose, which then circulates in the blood. In response, beta cells release insulin, which allows the body's cells to take in the circulating glucose. In this study, Taylor and his team exposed the mature stem cells to glucose and found that, like typical beta cells, the cultured cells responded by producing insulin. The team then injected diabetic mice with the mature, insulin-making stem cells. The mice had few working beta cells and very high levels of blood glucose.Mice that did not receive the stem cell therapy continued having high blood sugar levels, developed cataracts and were lethargic. In contrast, mice that received the cell therapy were active and did not develop cataracts, but the animals' blood sugar levels remained higher than normal.The Yale team's findings suggest that endometrial stem cells could be used to develop insulin-producing islet cells, which are found in the pancreas. These islet cells could then be used to advance the study of islet cell transplantation to treat people with diabetes.Taylor said in a statement that the next step in the research will be to verify how long this treatment remains effective.

BEIJING, June 12 (Xinhua) -- A senior Chinese official has called the country's police to better serve the people when the Communist Party of China (CPC) is meeting the 90th founding anniversary.Zhou Yongkang, member of the Standing Committee of the Political Bureau of the CPC Central Committee, made the remark on Sunday evening in meeting with top 10 favorite police officers selected through a nationwide vote.The Ministry of Public Security (MOPS) and the China Central Television have jointly conducted My Favorite Police Officer Competition in the past eight years.This year's winners include 75-year-old detective Wu Guoqing, network security police officer Li Qing from Jiangsu Province, traffic police officer Wu Hao of Miao Nationality from Hunan Province, female SWAT team leader Pan Qin from Guizhou Province.Zhou said that this year's competition attracted more than 150 million online voters which means more and more people are supporting the activity, and all winners should cherish the honor and better serve the people on their own posts.The official called on police officers around the country to learn from the 10 favarite officers and other winners in the competition who have all made outstanding contribution to the security of the people and society.
