BEIJING, Aug. 10 (Xinhuanet) -- A new technology can tell pregnant women whether they're having a boy or girl as early as seven weeks into a pregnancy -- months earlier than usual, according to media reports Wednesday.The technology works by detecting "cell-free fetal DNA," or DNA from the fetus, which floats freely in a pregnant woman's blood, said author Diana Bianchi of the Tufts University School of Medicine in Boston. Her analysis of 57 studies from peer-reviewed medical journals showed that these blood tests, common in Europe but not in the U.S. can reveal a fetus' sex only a week or two after a pregnant woman misses her period. Women usually learn the fetus' sex through an ultrasound at 18 to 20 weeks.The technology will help families worried by having a child with rare genetic disorders that typically affect only boys, such as hemophilia or a type of muscular dystrophy, said Joseph Biggio, director of the Trimester Genetics Screening Clinic at the University of Alabama-Birmingham.If they're having a girl, however, they can stop worrying, he added, and avoid further invasive tests, which can provide a definitive answer about genetic disorders, but also increase the risk of miscarriage. Women who learn they're carrying boys would still need a definitive test, such as an amniocentesis, to find out if their fetus is affected.

BEIJING, July 17 (Xinhua) -- Iraqi Prime Minister Nouri al-Maliki arrived in Beijing Sunday night for his first official visit to China as a guest of his Chinese counterpart Wen Jiabao.During al-Maliki's stay in China from Sunday to Thursday, President Hu Jintao will meet with him, and Premier Wen will hold talks with the Iraqi prime minister, Chinese Foreign Ministry spokesman Hong Lei said earlier.China and Iraq share a traditional friendship, Hong said, adding that the two countries have witnessed smooth development of bilateral relations, steadily growing economic cooperation and increasing cultural exchanges."China is ready to work with the international community and to continue to provide assistance for the Iraqi people to improve their livelihoods," said the spokesman.

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.

SAN FRANCISCO, Aug. 2 (Xinhua) -- Social networking giant Facebook on Tuesday announced that it has bought Push Pop Press, a digital publishing company that develops the technology to help make interactive books optimized for iPad and other Apple devices."We're thrilled to confirm that we've acquired Push Pop Press, a startup whose groundbreaking software changes the way people publish and consume digital content," Facebook said in a statement.Push Pop Press was co-founded by Mike Matas and Kimon Tsinteris, both former Apple employees, and was known for teaming up with former U.S. vice president Al Gore to create a digital version of his book "Our Choice"."Although Facebook isn't planning to start publishing digital books, the ideas and technology behind Push Pop Press will be integrated with Facebook, giving people even richer ways to share their stories," Push Pop Press said in a statement posted on its website."With millions of people publishing to Facebook each day, we think it's going to be a great home for Push Pop Press," the statement added.Financial terms of the deal were not disclosed by the two companies.

WASHINGTON, Sept. 12 (Xinhua) -- An enzyme that appears to play a role in controlling the brain's response to nicotine and alcohol in mice might be a promising target for a drug that simultaneously would treat nicotine addiction and alcohol abuse in people, U.S. researchers find.Over the course of four weeks, mice genetically engineered to lack the gene for protein kinase C (PKC) epsilon consumed less of a nicotine-containing water solution than normal mice, and were less likely to return to a chamber in which they had been given nicotine. In contrast, normal mice steadily increased their consumption of nicotine solution while the mice lacking PKC epsilon did not.The study conducted by researchers at the Ernest Gallo Clinic and Research Center, affiliated with the University of California, San Francisco, appeared Monday in the online edition of the Proceedings of the National Academy of Sciences.In normal mice, as in humans, nicotine binds to a certain class of nicotinic receptors located on dopamine neurons, which causes dopamine to be released in the brain. Dopamine creates a feeling of enjoyment, and thus prompts a sense of reward. Researchers found that mice lacking PKC epsilon are deficient in these nicotinic receptors.The finding complements earlier research in which researchers found that mice genetically engineered to lack the PKC epsilon enzyme drank less alcohol than normal mice and were disinclined to return to a chamber in which they had been given alcohol."This could mean that these mice might not get the same sense of reward from nicotine or alcohol," said Gallo senior associate director and investigator Robert Messing. "The enzyme looks like it regulates the part of the reward system that involves these nicotinic receptors."The reward system is a complex of areas in the brain that affect craving for nicotine, alcohol and other addictive substances.The next step in the research, said Messing, would be to develop compounds that inhibit PKC epsilon. The ultimate goal, he added, would be medications that could be used "to take the edge off of addiction by helping people get over some of their reward craving."
