SAN FRANCISCO, June 28 (Xinhua) -- Google on Tuesday rolled out a new social networking service named "Google+", a long awaited move of the Internet search giant to crack the industry's social trend dominated by Facebook.Unlike Facebook, Google said that the project is designed for sharing with small groups like college roommates and parents. " Today's online services turn friendship into fast food, wrapping everyone in 'friend' paper," Google said in a blog post announcing the new service.Other Google+ features include Sparks, which gathers articles and videos on topics of interests or hobbies; and Hangouts, which allows users join live multi-person video chat.There is also a mobile version of Google+ for smartphones running Google's Android operating system, which enables multi- person text message chats and instant upload of photos from the phone.The Google+ project is currently in field trial and by invitation only. Users can select people from their Gmail contacts and organize them into different groups.Google+ is expected to test whether Google could come back from its past frustration in social networking, such as Buzz, a social networking and messaging too integrated into its Gmail service. Some of Google Buzz's features have been widely criticized for privacy concerns.Market research data show that Facebook has surpassed Google in terms of time spent on each site, a fact that advertisers attach importance to.According to Internet market research company comScore, including YouTube, 180 million people visited Google sites in May, compare to 157.2 million on Facebook. However, Facebook users looked at 103 billion pages and spent an average of 375 minutes on the site, while Google users viewed 46.3 billion pages and spent 231 minutes.In April, Google CEO and co-founder Larry Page reportedly sent out a company-wide memo alerting employees that 25 percent of their annual bonus will be tied to the success or failure of Google's social strategy in 2011.

LOS ANGELES, June 3 (Xinhua) -- Eating earth may protect the stomach against toxins, parasites and pathogens, a new study suggests.To examine the possible benefits from eating earth, researchers at Cornell University analyzed reports from missionaries, plantation doctors, explorers, and anthropologists to put together a database of more than 480 cultural accounts of geophagy -- the eating of earth.The database includes as many details as possible about the circumstances under which earth was consumed, and by whom. The researchers could then use patterns in the data to evaluate each potential explanation.Studies in the database indicate that geophagy is common even when food is plentiful. Moreover, when people eat dirt they tend to eat only small quantities that are unlikely to fill an empty stomach.The database shows that geophagy is documented most commonly in women in the early stages of pregnancy and in pre-adolescent children. Both categories of people are especially sensitive to parasites and pathogens, according to the researchers.In addition, geophagy is most common in tropical climates where foodborne microbes are abundant. Finally, the database shows that people often eat earth during episodes of gastrointestinal stress.It's unlikely the intestinal problems are caused by the dirt itself because the type of clay people usually eat comes from deep in the ground, where pathogens and parasites are unlikely to contaminate it. Plus, people usually boil the clay before eating it.More study would be helpful to confirm the protection hypothesis, the researchers say, but the available data at this point clearly support it over the other explanations for eating earth."We hope this paper stimulates (more) research," said Sera Young, a researcher at Cornell University and the study's lead author. "More importantly, we hope readers agree that it is time to stop regarding geophagy as a bizarre, non-adaptive gustatory mistake.""With these data, it is clear that geophagy is a widespread behavior in humans ...that occurs during both vulnerable life stages and when facing ecological conditions that require protection."The study is appearing in the June issue of The Quarterly Review of Biology.

MOSCOW, June 27 (Xinhua) -- Russia successfully launched a Cosmos class military satellite on Monday, said spokesman of the Russian Space Forces Alexei Zolotukhin.A Soyuz-U carrier rocket carrying the military satellite blasted off from the Plesetsk Plesetsk space center in northern Russia at 20:00 Moscow time (1600 GMT), Zolotukhin said."The rocket put the Cosmos series military satellite into the designated orbit at 20:08 Moscow time (1608 GMT)," he added.The spokesman also said the launch of the Soyuz-U carrier rocket "was the first time for this type of rockets" in this year.The launch carried out by a team from the Russian Space Forces was supervised by Space Forces Commander Oleg Ostapenko.The satellite, Cosmos-2472, is a new member to a Russian network of about 60-70 military reconnaissance satellites.

MOSCOW, Aug. 26 (Xinhua) -- Russia will carry out two unmanned test launches of Soyuz carrier rockets in the coming fall before delivering crews to the International Space Station (ISS), local media reported on Friday.Citing a source, RIA Novosti news agency said that one of the Soyuz rockets was scheduled to send a new Progress M-13M space freighter to the ISS.On Wednesday, a Progress M-12M cargo ship failed to reach the orbit after the engine of a Soyuz-U carrier rocket turned off during the ascend. Soon after the accident, Russia announced it will temporarily ground all Soyuz rockets.Due to the accident, Russian space authorities have put off Thursday's launch of a Soyuz-2 carrier rocket from the Plesetsk Space Center in northern Russia and a launch of a manned space ship from Baikonur space center in Kazakhstan.After the retirement of the U.S. shuttle fleet, Russia's Soyuz spacecrafts have become the only way for astronauts to reach the ISS until at least the middle of the decade.

BEIJING, Sept. 1 (Xinhua) -- Chinese scientists have decided to reschedule the launch of the Tiangong-1, an unmanned space module, due to the failed launch of an experimental orbiter, a spokesperson with the project said Thursday.The decision to delay the launch was based on the consideration that the carrier rocket Long-March II-F, which would be used for the upcoming launch, belongs to the same series as the malfunctioning one that led to the experimental orbiter SJ-11-04 failing to enter Earth's orbit in August."As the investigation into the malfunction of the rocket Long-March II-C remains underway, it is not clear yet whether the malfunction is linked with the Long-March II-F," the unnamed spokesperson said.Previously, the Long-March II-F was expected to send the 8.5-metric ton Tiangong-1, or "Heavenly Palace 1," into space in the second half of this year to perform the nation's first space-docking procedure.The Tiangong-1 will dock with the unmanned Shenzhou-8 spacecraft, which will be sent into space after the Tiangong-1's launch."The specific launch date for the Tiangong-1 will be set based on the results of the investigation into the malfunctioning rocket," the spokesperson said, adding that the project's teams are currently double-checking every product that will be involved in the space-docking.The Shenzhou-8 spacecraft, the Long March II-F carrier rocket, and the Tiangong-1 have all been transferred to the Jiuquan Satellite Launch Center in northwest China's Gansu Province, the spokesperson said.
