BEIJING, Aug. 27 (Xinhua) -- Heavy rain battered several east China provinces Saturday, destroying homes and farmlands, while drought persisted in some of the country's arid central and southwestern regions.On Friday and Saturday, five counties in Anhui Province were hit by downpour, the provincial meteorological bureau said.It said 23 towns reported over 200 mm of rainfall in the 24 hours from 8 a.m. Friday to 8 a.m. Saturday. In some villages of Huaiyuan County, the precipitation topped 300 mm, about one third of the annual average volume.In Fengtai County alone, 2,048 people were stranded by rain-triggered flood. As of 9 p.m. Saturday, about 800 of them were still waiting for evacuation.Incomplete statistics provided by the provincial government said 280 houses toppled in the rain disaster and another 580 homes were damaged. About 54,800 hectares of cropland was drowned by rain and flood.The direct economic loss was estimated at 240 million yuan (37.6 million U.S. dollars), the provincial government said Saturday night.The provincial weather bureau forecast heavy rain will continue in most parts of Anhui in the coming three days.Heavy rain also wreaked havoc in seven cities and counties of the eastern Shandong Province, causing 230 million yuan of direct economic losses.Torrential rain that lasted more than 24 hours from Friday to Saturday afternoon forced evacuation of nearly 2,000 people in parts of Zaozhuang, Liaocheng and Linyi cities, the provincial civil affairs department said.It said nearly 500 homes toppled and more than 800 others were damaged.China Meteorological Administration has forecast heavy rain in the coming three days in Anhui, Shandong, Liaoning, Jiangxi provinces and parts of the Xinjiang Uygur Autonomous Region in the coming two to three days.Little rain has been predicted, however, for the drought-hit provinces in central and southwestern China, the administration said on its website.While the predicted rainfall for Guizhou, Sichuan, Chongqing, Yunnan, Hunan and Guangxi averages only 2 to 8 mm in four days from Aug. 28 to 31, it said the high temperature in these areas will still hover over 35 degrees Celsius.Affected by the approaching Typhoon Nanmadol, the coastal areas of Guangdong Province will experience high tides Sunday, but the scorching weather will stay next week, the provincial weather bureau said.The high temperature in most parts of the province has topped 35 degrees Celsius.

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.

SAN FRANCISCO, Sept. 2 (Xinhua) -- A late-season potato blight has been detected on farms in Alaska, only the fourth time the disease appear in the U.S. state since 1995, local media reported on Friday.The disease was found this week in the fields of potato producers in cities of Delta Junction and Palmer, according to the Fairbanks Daily News-Miner, Alaska's second largest daily newspaper.Farmers in both fields are working to prevent the spread of the blight, a fungus-like disease that can kill plants in the field or cause potatoes to rot in storage, the newspaper reported.Growers have been asked to kill all affected plants within 100 feet, and plant samples from both sites will be examined to identify what type of late blight is involved.Experts said that blight can be controlled through the use of fungicides, but the cool, damp weather this summer in the areas has created an ideal environment for the disease to spread.Although Alaska's potato crop is tiny compared to other U.S. states, it has been viewed as a possible global source of seed potatoes in recent years because it is largely free of disease.A local university has explored partnerships with Chinese growers to export certified seed potatoes, noted the Fairbanks Daily News-Miner report.

BEIJING, Sept. 6 (Xinhuanet) -- Scientists from Tufts University of the U.S. have created the world's smallest electrical motor in a single molecule.The finding was published in the journal Nature Nanotechnology on Monday.In the research, scientist successfully made a single molecule accept an electrical charge and rotate as fast as 120 revolutions per second."This is the first time that electrically-driven molecular motors have been demonstrated, despite a few theoretical proposals," said Charles H. Sykes, professor of chemistry at Tufts who led the team.The single molecule electric motor could lead to new types of electrical circuitry, giving hope for scientists to apply it in medicine and engineering, he said."The next thing to do is to couple it to other molecules, lining them up next to one another so they're like miniature cog-wheels, and then watch the rotation propagation down the chain," said Sykes.

SAN FRANCISCO, Sept. 22 (Xinhua) -- Facebook on Thursday introduced a new feature called Open Graph, enabling users to access and share a wide range of media and lifestyle content on the social network site.According to Facebook's chief executive officer (CEO) Mark Zuckerberg, Open Graph lets users share what they are doing in Facebook-connected apps as they are doing it.These social apps focus on media apps including books, news, music, TV, movies and games, as well as lifestyle apps such as exercise, food, fashion and travel."The last five years of social networking have been about getting people signed up, and getting people connected with their lives. The next five years are going to be defined by the apps and depth of engagement," the young CEO said in a keynote speech at Facebook's f8 developer conference.Take music for example, Facebook integrates with European music streaming service Spotify. If one's Spotify account is connected to Facebook, a message will show up in the Ticker stating the song one is listening to and in the Timeline, a new design of one's profile page. The friends of the user can listen to the same song at the same time by hovering mouse over the song in Timeline or Ticker.Spotify founder and CEO Daniel Ek and movie streaming service Netflix CEO Reed Hastings also took stage as guest speakers to introduce their partnership with Facebook.Zuckerberg also introduced social news reading applications from major news organizations such as The Washington Post and Yahoo News, which allow users to access the content directly on Facebook.Earlier at the f8 conference, Timeline was unveiled as a new feature. It is a new profile design allowing users to scroll vertically through the big moments of one's life in a single page.Zuckerberg assured users that they have complete control over their Timeline, saying they can decide what content will appear and who can see it. The new feature will be available in a few weeks.Since Google launched its own social network "Google+" in June, Facebook has been in a combat mode, striving to roll out new products and features to beat the search giant. In his keynote speech on Thursday, Zuckerberg said half a billion people now use Facebook every day.Two days before the f8 conference, Google announced to open its social network to the public, noting it has introduced 100 new features in the three-month trial.
