BEIJING, August 4 (Xinhuanet) -- Medtronic Inc. is giving Yale University a 2.5 million U.S. dollar grant to review the safety and effectiveness of its controversial spine treatment called Infuse Bone Graft, according to The Wall Street Journals Thursday.Under terms of the pact, the company will release to Yale and eventually the public what participants described as an unprecedented amount of clinical trial and other data. The university will select two research teams from other organizations to perform separate analyses of the data.The announcement comes in the wake of a paper in June in the Spine Journal. The paper revealed that several clinical studies of Infuse, conducted by surgeons with strong economic ties to Medtronic, failed to report serious complications that arose in the trials. The critical paper also found that many of the studies were designed in ways in favor of Infuse over a treatment given to a control group.Medtronic disputes some of the findings and is conducting an internal investigation of the matter.Infuse accounts for about 700 million dollars in annual sales for Medtronic. The product is under investigation by the Senate Finance Committee over the role payments to physicians who may have played how studies were reported.

BEIJING, Sept. 26 (Xinhuanet) -- Young unmarried migrant women are facing a high risk of induced abortions in China and experts urged that they have better access to reproductive health education.Among the 8 to 10 million induced abortions performed on the mainland each year, nearly 47 percent involve unmarried women younger than 25, according to Cheng Linan, director of the center for clinical research and training of the Shanghai Institute of Planned Parenthood Research.The statistics are based on the results from a recent nationwide survey."The rising trend of induced abortions is even more evident among migrants who usually have poor awareness and access to reproductive health knowledge and services, particularly about contraception," she said on Saturday at an event to mark World Contraceptive Day, which falls on Sept 26.A 2008 survey involving more than 50,000 induced abortions in Beijing showed that roughly 70 percent of the women undergoing the procedure were migrants. For many, it was not their first abortion.According to a nationwide study by the Chinese Medical Association (CMA), of all women having received induced abortions, nearly 56 percent had two operations and 13.5 percent had three or more."That not only causes the women certain physical or mental problems, but it also gives the country a huge economic burden of more than 3 billion yuan" or about 0 million, she said.Among Chinese women who became infertile, more than 88 percent previously had an induced abortion, a study conducted in 2007 showed.Other potential health hazards include hemorrhage, uterine or pelvic infection, uterine perforation and cervical laceration.Apart from low awareness, poor access to professional consultations on contraception, particularly among single young women, is mainly the problem.A 2011 survey by the CMA found that about 44 percent of those polled said they had difficulty accessing scientifically correct contraceptive information, compared with a global average of 15.5 percent.

BEIJING, July 27 (Xinhuanet) -- Amazon.com’s e-book reader Kindle 3G with special offers is now the company’s top-selling e-book device, according to media reports on Wednesday.Amazon revealed in its quarterly earnings report that the ad-supported version costs 139 U.S. dollars,  50 dollars cheaper than the comparable Kindle 3G, and costs the same as a Kindle with Wi-Fi connectivity. Many believe Kindle is the most popular dedicated e-book device on the market today.The advertisements will appear only in screensavers (which appear when the reader is in an idle state) and at the bottom of the home screen, so they don’t interrupt readers.“Since AT&T agreed to sponsor screensavers, Kindle 3G with Special Offers is now our bestselling Kindle device,” Amazon’s press release said.Having zoomed past the earlier Sony Reader, and kicked off a wave of competition including the Barnes & Noble Nook and the Kobo E-Reader, Kindle is believed the most popular dedicated e-book device on the market today.

WASHINGTON, June 6 (Xinhua) -- Forests in many regions are becoming larger carbon sinks thanks to higher density, U.S. and European researchers say in a new report.In Europe and North America, increased density significantly raised carbon storage despite little or no expansion of forest area, according to the study, led by Aapo Rautiainen of the University of Helsinki, Finland, and published Monday in the on- line, open-access journal PLoS One.Even in the South American nations studied, more density helped maintain regional carbon levels in the face of deforestation.The researchers analyzed information from 68 nations, which together account for 72 percent of the world's forested land and 68 percent of reported carbon mass. They conclude that managing forests for timber growth and density offers a way to increase stored carbon, even with little or no expansion of forest area."In 2004 emissions and removals of carbon dioxide from land use, land-use change and forestry comprised about one fifth of total emissions. Tempering the fifth by slowing or reversing the loss of carbon in forests would be a worthwhile mitigation. The great role of density means that not only conservation of forest area but also managing denser, healthier forests can mitigate carbon emission," says Rautiainen.

SAN FRANCISCO, June 14 (Xinhua) -- Google on Tuesday unveiled voice search for desktop computers and search-by-image, two new features allowing users to speak their search into the computer and search with the help of images.Speaking at the Internet search giant's Inside Search Event in San Francisco, Mike Cohen, head of Google's speech technology efforts, said its voice search is now available in 27 languages and dialects, an estimated coverage of around 5 billion people or two-thirds of world population.Voice search has already been available in Google's mobile search application from 2008. Adding the feature to desktops is part of Google's strategy to bring mobile innovations to its desktop search.The voice search on desktop performs similarly to voice search on smartphones -- users can click the microphone button and speak the query. It is only available via Google's Chrome browser for now.Cohen noted that the volume of Google mobile speech inputs has increased by six times in the last year.Also at the event, Google introduced search-by-image, which enables users to drag-and-drop, copy-and-paste image URL, or upload the image from the desktop into the search box. They can also use a Chrome or FireFox software extension to add images to the search.Google said the search-by-image feature will be available in most countries and regions over the next few days to Chrome users, noting that it will not collect and store any images that users use.
