BEIJING, June 20 (Xinhuanet) -- More Chinese cities have seen month-on-month declines in the prices of both new and secondhand homes, according to the National Bureau of Statistics (NBS) on Saturday.The NBS said in a statement on its website that month-on-month price growth for new commercial homes was reported in 50 out of the NBS's statistical pool of 70 major cities. That compared to 56 cities reporting month-on-month growth in April.New home prices declined from a month ago in nine cities and stood unchanged in 11 cities, while 27 cities posted smaller monthly price gains, said the NBS.As for resold housing units, 23 cities reported second-hand home price declines month-on-month in May, up from 16 in April. Secondhand home prices stayed unchanged in 11 major cities in May from April, according to the NBS.On a year-on-year basis, the prices of new commercial homes declined in three cities, including Hangzhou and Sanya, both of which were hot spots for real estate speculation in the past. Meanwhile, 36 cities saw lower year-on-year growth, up from 29 in April, said the NBS.Secondhand home prices dropped in four cities from one year ago, while 29 cities reported declines in year-on-year price growth from April.The NBS stopped releasing overall housing prices for 70 major cities in January, citing the fact that overall price figures for the cities failed to reflect regional differences. The NBS is also using a new surveying method to determine price changes.The government has adopted various measures to cool the property market and curb rising prices, including restricting residents in major cities from buying second or third homes, requiring higher down payments for mortgages and instituting new property taxes in the cities of Chongqing and Shanghai.But there has not been a significant drop in home prices. The latest central bank survey of urban bank depositors found that more than one-third of respondents anticipated home prices would remain stable in the second half of the year.The survey, which is carried out quarterly among 20,000 urban bank depositors in 50 major cities, said 25.9 percent of respondents believed prices would continue to rise, while only 18.9 percent expected a decline.Meanwhile, the survey showed that 74.3 percent of residents said housing prices in the second quarter were "too high to afford", almost the same as during the first quarter.Experts and market observers said the Chinese property market is stagnant with home transactions remaining grim and no clear trend in prices.Yang Hongxu, an analyst with the Shanghai-based E-house China Research and Development Institute, said the May figure has continued April's downward trend in prices, but the cooling of the market will happen gradually.The NBS announced on Tuesday that property developers sold 329.32 million square meters of commercial houses nationwide in the first five months of this year, an increase of only 9.1 percent year-on-year.The NBS said that investment in the nation's property sector has maintained strong growth by rising 34.6 percent year-on-year to reach 1.87 trillion yuan (8.6 billion) in the January-May period, which might have been a result of affordable housing investment.Figures from the NBS also reflected that property developers are getting less funding from banks, as the government continued to raise borrowing costs for developers and tighten liquidity in the market.Developers obtained 580.3 billion yuan from domestic loans in the first five months, up 4.6 percent year-on-year. Meanwhile, they used 26.6 billion yuan of foreign investment in the sector, posting a year-on-year rise of 57.3 percent.

BEIJING, Aug. 15 (Xinhua) -- Scientists in a lab with Daya Bay Nuclear Power Station in southern Guangdong Province have found neutrino through two detecting instruments, which is likely to provide clues to solving the mystery of why there is more matter than antimatter in the universe.The Institute of High Energy Physics with the Chinese Academy of Sciences on Monday announced the breakthrough that was achieved by more than 250 researchers from six countries and regions.The two neutrino detectors are installed underground 360 meters away from the nuclear plant at a depth of 100 meters.Scientists believe that matter and antimatter were created in equal amounts during the Big Bang, but the disappearance of antimatter remains a mystery.Neutrino is an elementary particle that is able to pass through ordinary matter almost unaffected, which makes it extremely difficult to detect.Located in Shenzhen, a city neighboring Hong Kong, the Daya Bay Nuclear Power Station commenced operation in 1993.Scientists from the Chinese Academy of Sciences and the U.S.-based Brookhaven National Laboratory and the Lawrence Berkeley National Laboratory started the underground neutrino experiment in 2006.Kam-Biu Luk, spokesman for the laboratory, said that the results of the experiment would further shed light on the evolution of basic matter after the Big Bang.The neutrino experiment in the Daya Bay is one of the largest cooperation projects with regards to basic research between China and the United States.Among the participants of the experiment are Russia, Czech Republic, and China's Hong Kong and Taiwan regions.

SAN FRANCISCO, June 8 (Xinhua) -- Facebook Inc. will be probed by European Union (EU) regulators over its latest facial recognition feature rolling out worldwide, U.S. media reported on Wednesday.The feature, called Tag Suggestions, uses face recognition software to match users' new photos to other photos they are tagged in. It groups similar photos together and suggests the name of the friend in the photos.Facebook rolled out the feature in the United States late last year, where users can opt out of the feature by going to their private settings. But Facebook switched it on by default without telling users first when it became available on Tuesday in countries outside of the United States.A group of privacy watchdogs from 27 EU nations will study the measure for possible rule violations, a Luxembourg official of Article 29 Data Protection Working Party told Bloomberg. The Working Party, an independent EU advisory body on data protection and privacy, comprises the data protection regulators of all the 27 EU member states."Tags of people on pictures should only happen based on people' s prior consent and it can't be activated by default," said the Luxembourg official, Gerald Lommel. He noted that such automatic features "can bear a lot of risks for users" and the European data- protection regulators will "clarify to Facebook that this can't happen like this."Authorities in Britain and Ireland said they are also looking into the new function on Facebook. The British Information Commissioner's Office told Bloomberg that "the privacy issues that this new software might raise are obvious," saying it is "speaking to Facebook" about the issue.Facebook has been under scrutiny by EU regulators for several privacy concerns, such as users' default settings and how the company uses the information collected from its social network website.

SAN FRANCISCO, July 6 (Xinhua) -- Facebook on Wednesday introduced a new video calling feature powered by Skype and some improvements to the chat designs on the social networking site.According to Facebook, users can reach video calling from a new "Call" button on a friend's profile or from the chat panel after downloading a Skype application. A recipient will receive an alert that they are being called and can then accept or decline.At the press event held at Facebook headquarters in Palo Alto, California, CEO Mark Zuckerberg said the feature will begin with one-on-one video chat. Skype CEO Tony Bates, whose company has been acquired by Microsoft, said Skype is considering having its paid product within the Facebook product.The social networking company also introduced "Ad Hoc Group Chat", which enables users to start a group chat instantly without creating a group with those multiple friends at first. The new group chat feature is also available for Facebook's mobile interfaces.Facebook also introduces a sidebar that lists the people a user messages most, enabling users to chat with close friends, professional contacts or co-workers without being interrupted. The sidebar can adjust with the size of users' browser window and automatically appears when the window is wide enough.In the opening remarks at the press event, Zuckerberg confirmed that Facebook had surpassed 750 million monthly active users. He said the company had declined to announce the number earlier because it has become focused on other metrics, like how actively users are sharing information.The CEO said users are now sharing 4 billion "things" on Facebook every day, which grew at an exponential rate compared to the amount users share a year ago."Social networking is at an inflection point," said Zuckerberg, adding that he believes social networking now is more about the strength of connecting people rather than the quantity of users or ubiquity of the technology.Zuckerberg presented a graph to show how Facebook product launches have helped drive the growth of sharing. He said the social network expects more innovations from other companies involved in everything from music to communication to help drive the growth.

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.
