CANBERRA, Sept. 9 (Xinhua) -- Australia on Friday launched the first national study to find out whether low to moderate levels of alcohol drank by pregnant women are harmful or not to an unborn child, hoping to provide a clear indication about the safe amount of alcohol for pregnant women.The Murdoch Children's Research Institute in Melbourne, which commissioned the study, is recruiting 2000 pregnant women who will be quizzed throughout their pregnancy about their drinking habits, general health and diets.Their babies will then undergo medical checks, when they turn one and again at two to see if their brains, development and behavior was affected by alcohol consumed by their mums.According to lead researcher associate professor, Jane Halliday, while there was solid evidence about the dangers of heavy drinking for an unborn baby, it was not known if there was a safe amount of alcohol pregnant women could drink.She said the study hoped to shed light on the best approach to alcohol use during pregnancy."The problem is that for about half of women that get pregnant it is unplanned, and a lot of women are drinking around the time they get pregnant and may drink for the first month or so and that creates a lot of anxiety," Assoc Prof Halliday said in a statement."From the few international and Australian studies there's conflicting evidence as to whether there's an adverse effect."We firmly believe that no drinking is the safest option, but our main aim is to provide an evidence base to the policy and answer questions about individual risks."The study came after research by the University of Newcastle published in 2010 revealed 80 percent of Australian women drank during pregnancy.

BEIJING, July 26 (Xinhuanet) -- Seven of the 20 top selling American prescription drugs will lose their patents by the end of next year, making way for less expensive generic versions, according to media reports.It's a shift that could save consumers billions of dollars -- assuming those big-ticket medications are willing to give up a trusted brand name for an off-label replacement.The prices of medications such as cholesterol-fighting Lipitor and blood thinner Plavix are expected to go down significantly, according to the U.S. Food and Drug Administration (FDA).Lipitor will lose its patent in November. When that patent expires, people are advised to buy atorvastatin, the generic equivalent. Other brand names include the anti-psychotic Zyprexa and the rheumatoid arthritis and psoriasis drug Enbrel, of which the patent will expire in October and October of next year, respectively.Over the next 10 years, an estimated 120 more brand-name prescription drugs will lose their patents in the U.S.

BEIJING, Aug. 26 (Xinhua) -- China's maritime authority on Friday once again urged U.S. oil giant ConocoPhillips to finish cleaning up oil spills in north China's Bohai Bay as soon as possible.Aug. 31 is the deadline set by the government. "There are only five days to go before the arrival of the deadline," said a statement of the State Oceanic Administration (SOA).The SOA urged ConocoPhillips China to adopt all technical measures that could be used to clean up oil spills, and to do it "with an active manner."Liu Cigui, head of the SOA, said Thursday that his administration is collecting evidence and gauging the ecological impact of the spills in preparation for possible legal action against the company.ConocoPhillips China, a subsidiary of ConocoPhillips, first reported the oil spills in June. The spills have spread to beaches in Hebei and Liaoning provinces and been blamed for losses in local tourism and aquatic farming industries.Although the company has worked to clean up the spills, pollutants have still been found in the bay, even after cleanup efforts were reported to be complete.ConocoPhillips China admitted that a total of 16 oil spill sources have been found in the bay as of Friday.

LOS ANGELES, June 20 (Xinhua) -- NASA's Cassini spacecraft has successfully completed its second-closest encounter with Saturn's icy moon Helene, beaming down raw images of the small moon, the Jet Propulsion Laboratory (JPL) said on Monday.At closest approach on June 18 Cassini flew within 4,330 miles (6,968 kilometers) of Helene's surface, the second closest approach to Helene of the entire mission, said JPL in Pasadena, Los Angeles.This flyby will enable scientists to finish creating a global map of Helene, so they can better understand the history of impacts to the moon and gully-like features seen on previous flybys, according to JPL.Passing from Helene's night side to the moon's sunlit side, Cassini also captured images of the Saturn-facing side of the moon in sunlight, a region that was only illuminated by sunlight reflected off Saturn the last time Cassini closely encountered with the moon in March 2010.The closest Helene encounter of the mission took place on March 10, 2010, when Cassini flew within 1,131 miles (1,820 kilometers) of the moon.The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency.JPL, a division of the California Institute of Technology in Pasadena, manages the Cassini-Huygens mission for NASA's Science Mission Directorate, Washington. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL, while the imaging team is based at the Space Science Institute in Boulder, Colorado.
