WASHINGTON, Aug. 11 (Xinhua) -- The unique fossils of an adult plesiosaur and its unborn baby may provide the first evidence that these ancient animals gave live birth like mammals, according to a new study to be published Friday in the journal Science.The 78-million-year-old, 15.4-foot-long (4.7-meter-long) adult specimen is a Polycotylus latippinus, one of the giant, carnivorous, four-flippered reptiles that lived during the Mesozoic Era.Dr. Robin O'Keefe of Marshall University in West Virginia and Dr. Luis Chiappe, Dinosaur Institute director of the Natural History Museum in Los Angeles County, have determined that it is the fossil of an embryonic marine reptile contained within the fossil of its mother.The embryonic skeleton contained within shows much of the developing body, including ribs, 20 vertebrae, shoulders, hips, and paddle bones.O'Keefe and Chiappe have also determined that plesiosaurs were unique among aquatic reptiles in giving birth to a single, large offspring, and that they may have lived in social groups and engaged in parental care.Although live birth has been documented in several other groups of Mesozoic aquatic reptiles, no previous evidence of it has been found in the important order of plesiosaurs."Scientists have long known that the bodies of plesiosaurs were not well suited to climbing onto land and laying eggs in a nest," O'Keefe said."So the lack of evidence of live birth in plesiosaurs has been puzzling. This fossil documents live birth in plesiosaurs for the first time, and so finally resolves this mystery."

SAN FRANCISCO, July 12 (Xinhua) -- Facebook and Time Warner announced on Tuesday that they are teaming up to launch a wide- ranging, major cross-platform partnership initiative to fight bullying.The multi-media campaign, named "Stop Bullying: Speak Up" after the original anti-bullying initiative by Time Warner's Cartoon Network, will integrate broadcast, print, online and social media to educate parents, teachers and youth about the actions that will help protect young people from the impact of bullying, the two said in a joint statement.As part of the initiative, Facebook is scheduled to launch an interactive application in the back-to-school season this fall, which will enable educators, parents, and kids to make a personal commitment to help stop bullying."We care deeply about the safety of our nation's children and are proud to be partnering with Time Warner to raise awareness of bullying," Sheryl Sandberg, Facebook's chief operating officer, said in the statement."We believe that by working together with parents and teachers, we can teach young people to speak up and stop bullying," she added.Time Warner is also planning to expand its multiplatform efforts to communicate the anti-bullying message to an broader audience.It said in October, three of its magazines -- People, Sports Illustrated and Time -- and their affiliated websites will feature editorial content that highlights the problem of bullying and innovative programs and measures being taken to combat it.In partnership with Facebook, CNN's Anderson Cooper will also host a new town hall, which is scheduled to air in October and will be dedicated to discussing bullying issues confronting kids today as well as discussions with experts to teach adults on coping with the bullying epidemic."I'm confident that through our multiplatform approach and combined resources we can inspire even more people to take action against bullying," said Jeff Bewkes, Time Warner's chairman and chief executive officer.

coastline in the U.S. State of California sampled by the state water board harbored fish with mercury in such high concentrations that they shouldn't be eaten by young women and children, a newly released survey has found.Fourteen percent of locations had similarly elevated levels of PCBs, according to the survey published by The Los Angeles Times on Sunday.The most elevated concentrations of mercury and PCBs were found in San Francisco Bay and San Diego Bay, said the survey funded by the state water board.The findings, part of a two-year inquiry that is the largest statewide survey of contaminants in sport fish along the California coast, examined more than 2,000 fish from three dozen species gathered in 2009 from waters near Los Angeles, San Francisco and San Diego, the paper said.The survey highlights the health problem of lingering mercury, a poisonous metal that is found in fish globally, and of PCBs, toxic chemicals the United States banned in the 1970s, the report said.Both substances continue to pose a risk to people who eat fish caught along the California coast because they can lead to nervous system damage and developmental problems in children and can cause cancer, liver damage and reproductive harm, the report quoted researchers as saying."Unfortunately, we're not seeing many areas that are totally clean," said Jay Davis, a senior scientist for the San Francisco Estuary Institute and lead author of the study. But a catalog of where and in what fish the substances abound should help anglers make better choices, Davis said. "With good information, people can reduce their exposure significantly."Sharks had some of the highest levels of mercury because of their unusual tendency to accumulate contaminants in their flesh, while chub mackerel had the lowest levels of contamination, according to the survey.The survey results were used in part to help craft new fish consumption guidelines issued earlier this week for anglers in San Francisco Bay, the first update there by state health officials in 17 years. The advisory identifies shiner perch and other surf perches as unsafe to eat in any quantity and warns young women and children not to eat white sturgeon, striped bass and sharks caught in the bay, The Times said.The buildup of metals and other chemicals in fish is such a problem along the Southern California coast that health officials two years ago expanded the number of fish species on the "do not eat" list from one to five because of high levels of PCBs, mercury and the banned pesticide DDT, the report noted.

SINGAPORE, July 3 (Xinhua) -- The over 60 nursing homes in Singapore, especially those run by voluntary welfare organizations, are facing a bed crunch, local daily Straits Times reported on Sunday.The newspaper found in a check with 20 homes that more than half of the nursing homes were running at full or almost full capacity. Homes run by voluntary welfare organizations, where there are subsidized beds, have long waiting lists.The average waiting time for a bed in nursing homes run by voluntary welfare organizations rose from 50 days in 2008 to about 60 days early last year, the newspaper said.It is easier to get a bed in a privately run home, though only slightly and if you can afford it. Econ Healthcare Group, which runs eight nursing homes in Singapore, said the occupancy rate is 99 percent and it has waiting lists of up to 20 people at some branches.Demand for nursing homes in the city state can only grow given the aging population. By 2030, the number of people aged 65 or above is projected to reach 900,000, or one in every five residents.

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.
