SAN FRANCISCO, Sept. 27 (Xinhua) -- Apple on Tuesday announced an invitation-only special event featuring iPhone on Oct. 4, 2011.With a simple headline reading "Let's talk iPhone," the invitation said that there will be an "executive presentation at 10 a.m.." This could be the first big product introduction by the newly installed Chief Executive Officer Tim Cook after he took over the reins of Apple from Steve Jobs in August.The event, which will be held at Apple campus in Cupertino, California, has long been reported to be the introduction of iPhone 5, the next generation iPhone.According to U.S. media reports, the iPhone 5 is expected to have revamped hardware design with a larger screen, a higher resolution camera and a faster dual-core A5 chip on which the iPad 2 runs. Apple is also reported to release a low-cost and contract- free iPhone model bundled with its cloud computing service iCloud.

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.

BEIJING, Sept. 26 (Xinhuanet) -- Weather forecasts showed that Thursday or Friday might be suitable for launching the Tiangong-1 spacecraft, experts said.The unmanned spacecraft, part of China's first spacecraft rendezvous and docking mission, was set to blast off from the Jiuquan Satellite Launch Center in Northwest China at an appropriate time between Tuesday and Friday.But the latest weather forecast showed that Tuesday and Wednesday would not be suitable for a launch, Cui Jijun, chief commander of the mission's launch site system, was quoted by China National Radio as saying on Sunday.A precondition for launching is that the average wind speed at the launch site should not be faster than 10 meters a second. The upper-level wind, at 300 meters to 25,000 meters above the Earth, should be no faster than 70 meters a second.The 8.5-ton Tiangong-1 spacecraft and the Long March II-F rocket stand at the Jiuquan Satellite Launch Center on Sept 20. The spacecraft is set to blast off at an appropriate time between Tuesday and Friday.If the wind is too strong, the rising rocket carrier could wiggle and pose a danger, experts said."Everything is ready now except for the right weather," Cui said.On Sunday afternoon, all systems of the Tiangong-1 project went through a joint maneuver, he said. Before that, the 8.5-ton spacecraft, and the Long March II-F rocket that will carry it skyward, were positioned onto the launch pad last Tuesday.Engineers carried out checkups on the conditions of the rocket and the spacecraft, among many other tests in the past few days. All preparation work is done except for fuel loading, he said.Wang Xiaoqing, a publicity official at the launch site, said that the fuel loading usually begins one day before the launch. Once the fuel is loaded into the carrier vehicle, the launch becomes "irreversible".Tiangong-1, or Heavenly Palace 1, will serve as "a target spacecraft" for three rendezvous and docking experiments.The spacecraft rendezvous and docking missions are expected to pave the way for the building of a planned space station scheduled for 2020, previous reports said.Following Tiangong-1, an unmanned Shenzhou VIII spaceship will blast off from the Jiuquan Satellite Launch Center later this year.Lu Jinrong, chief engineer of the mission's launch site system, said that it is rare that two launches of China's manned space program are scheduled in half a year."In the past, the launch site carried out one launch a year, or even one every two to three years," he said."We are already in a high-frequency launch period."

BEIJING, Aug. 31 (Xinhuanet) – The pressure of modern society is taking a toll on sexual satisfaction, experts say following the release of an online survey.About 34 percent of people polled in the survey said that they are unsatisfied with their sex lives, with 6.5 percent "very unsatisfied".Another 32 percent condemned their sex lives as "just so-so".The survey interviewed more than 3,000 people, aged between 15 and 55, with men accounting for 74 percent of the interviewees.It was conducted by the China Population Communication Center and the Shanghai Academy of Social Sciences from May 1 to June 20. The survey did not give a margin of error.Only 23 percent of respondents said that they are "satisfied" with their sex lives, with 3.6 percent "very satisfied", according to the survey.But women seem to have a higher rate of satisfaction than men, with only 26 percent saying they are unsatisfied. The rate for men is 42 percent.The rate of sexual satisfaction among Chinese people is below the global average of 44 percent, according to an earlier survey by Durex. The 2007 Durex Global Sexual Wellbeing Survey questioned more than 26,000 people in 26 countries about all aspects of their sex lives - including satisfaction levels.Jiang Hui, president-elect of the Chinese Society of Andrology, attributed the lower rate of sexual satisfaction among Chinese people to rapid economic growth, which inevitably increases work and social pressure.Health problems associated with a modern lifestyle, such as diabetes and hypertension, are also to blame, he said.Jiang said his department of andrology used to receive about 10 patients a day 10 years ago. Now the figure has risen to more than 250.Rising awareness of sex and a more open attitude toward the once-taboo topic among the public also contributed to higher sexual expectations, he said.The survey also revealed that about 30 percent of respondents in the 35-55 age group had sex less than once a week."That rate is quite low, compared with the global average of 103 times a year, or 1.98 times a week," said Yang Xiong, who heads the social survey center at the Shanghai Academy of Social Sciences.Only 16.9 percent of respondents said that they had sex more than 10 times a month. Most respondents had sex three to nine times every month.About 8 percent of respondents said that they basically had no sex at all or it was too infrequent to be classified.The survey seemed to find that the more you made, the less you had. Those who earned at least 9,000 yuan (,400) a month had less sex than those who earned less, according to the survey.Among those making more than 9,000 yuan per month, over 70 percent said they had sex less than twice a month, compared with 16.5 percent for those with a monthly salary of less than 6,000 yuan.The survey also found that when people run into problems with their sex lives, 83 percent turn to the Internet, rather than professionals, for help. Less than 6 percent said they would see doctors to solve sex-related problems.Nearly 70 percent of those polled said they suffered from sexual health problems, such as erectile dysfunction (ED)."Many patients, especially men, are reluctant to see a doctor, which they think harms their manhood," Jiang said.According to a study conducted by the Chinese Society of Andrology, at least 40 percent of men aged 40 and above suffered from erectile dysfunction, roughly the global average.But Yang, from the Shanghai academy, noted that surveys conducted online tend to produce far different results than those conducted face-to-face.He expressed reservations about the survey's accuracy and said the public should only use the results for reference.

SINGAPORE, July 10 (Xinhua) -- The upcoming Natural History Museum in Singapore launched a drive on Sunday to raise 12 million Singapore dollars (9.8 million U.S. dollars) by the end of the month to buy three dinosaur fossils from a company in Wyoming, the United States.The three dinosaurs on offer from the company Dinosauria International, thought to be a family, were found between 2007 and last year in the United States, the Straits Times reported on Sunday.Appollo and Prince, the two adult diplodocid sauropods, is about 24 meters long, while the baby Twinky is about 12 meters.The natural history museum is expected to be completed by 2014. The three dinosaur fossils will cost 870 million Singapore dollars, and an additional 370 million Singapore dollars will be spent to set up the exhibition."They wanted the museum to tell the story of the history of life and evolution. Dinosaurs are the history of life," said Professor Peter Ng, director of the Raffles Museum of Biodiversity Research, referring to the approval from the scientific advisory committee for the acquisition.The Raffles Museum of Biodiversity Research of the National University of Singapore went on an intensive fund raising campaign last year to build the dedicated Natural History Museum.The museum said it has found the amount to be challenging. It is therefore appealing for help from the public through the media."The idea was always to have a central gallery and put something there that would make people go 'Whoa!,'" said Ng.
