PARIS, Sept. 21 (Xinhua) -- European heavy-lift launcher Ariane 5 lifted off two communication satellites Wednesday from the Kourou launch centre in French Guiana, live broadcast of the launching process showed.The rocket, carrying the two communication satellites Arabsat 5C and SES-2, was launched at GMT 2138.This was the fifth heavy-lift mission of Ariane 5 in 2011. Arianespace had planned six Ariane 5 missions through 2011.The satellite Arabsat-5C was developed for the Arab Satellite Communications Organization (Arabsat) to provide satellite capacity in both C-band and Ka-band frequencies for a wide range of communications services.Jointly produced by Europe's EADS Astrium and Thales Alenia Space, it will be positioned at 20 degree East orbital location to cover the Middle East and Africa.Manufactured by Orbital Sciences Corporation of the United States, SES-2 will join the fleet of European satellite telecommunications operator SES, and is to be positioned at 87 degree West for coverage over North America and the Caribbean.Both Arabsat-5C and SES-2 have life-spans as long as 15 years.This Ariane 5 dual-passenger mission was postponed from Tuesday due to local strikes of French Guiana workers.Founded in 1980 as the world's first launch service and solutions company, Arianespace planned to achieve six Ariane 5 missions through 2011. Through 2010, heavy-lift workhorse Ariane 5 finished six missions, sending a dozen spacecraft into expected orbits.The next mission from Arianespace centre in Kourou was scheduled for Oct. 20 by medium-lift vehicle Soyuz. It will be Soyuz' first mission from French Guiana with a pair of satellites for Europe's Galileo satellite navigation system.

LOS ANGELES, June 4 (Xinhua) -- Pregnant women who eat high-fat diet may be more likely to have a higher rate of stillbirth, a new study suggests.Researchers at Oregon Health & Science University (OHSH) came to the conclusion after observing 24 pregnant Japanese macaques that ate either a diet comprising 32 percent calories from fat or a control diet with 14 percent fat calories for at least four years.The researchers found the monkeys that ate a high-fat diet experienced a significant decrease in blood flow from the uterus to the placenta, a reduction of 38 percent to 56 percent, and a rise in placental inflammation.This was the case regardless of whether the monkeys were obese or slender. The risk of stillbirth was further compounded, however, when the monkeys were obese with hyper-insulinemia, or pre-diabetes.A large order of McDonald's french fries are shown May 22, 2008. McDonald's has switched to cooking oils free of trans fats in all of its restaurants in the United States and Canada, Chief Executive Jim Skinner said on may 23Eating a high-fat diet decreases blood flow from the mother to the placenta, the temporary organ that nourishes the unborn fetus, thus raising the risk of stillbirth, the researchers explained.Because the placental structure of the Japanese macaque is very similar to that in humans, cause and effect can be better established, the researchers said.Additional studies are needed to determine exactly how a high- fat diet decreases placental blood flow, the researchers noted.This is the first study to explain exactly how a fatty diet contributes to stillbirth, the researchers said in the study appearing in the June edition of the journal Endocrinology.The researchers hope their work will inform expectant moms and their physicians about the inherent dangers of a high-calorie, high- fat diet."This study demonstrates that maternal diet during pregnancy has a profound influence on both placental and fetal development," said Antonio Frias, M.D., principal investigator and assistant professor of obstetrics and gynecology (perinatology/maternal-fetal medicine) in the OHSU School of Medicine."The high-calorie, high-fat diet common in our society has negative effects on placental function and may be a significant contributor to adverse pregnancy outcomes, such as stillbirth."Previous studies have shown that nearly all adverse outcomes during pregnancy -- abnormal fetal growth, preeclampsia, preterm labor and stillbirth -- are in some way associated with an abnormally developed, or damaged, placenta, the temporary organ that nourishes the unborn fetus.In addition, maternal obesity has been associated with placental inflammation and dysfunction and an increased risk of stillbirth.Taking these findings into account, the researchers hypothesized that eating a diet high in fat during pregnancy also may increase the risk of placental inflammation and the risk of stillbirth.The researchers said they plan to conduct further studies on the impact of dietary changes and diet supplementation on improving outcomes in both monkeys and humans.

CANBERRA, Aug. 31 (Xinhua) -- Australia's new chief medical officer, Professor Chris Baggoley, on Wednesday said Australian should not be worried about reports that a mutant strain of the deadly bird flu virus is spreading across Asia and beyond.On Monday, the UN's Food and Agriculture Organization (FAO) said a mutant strain of the deadly avian influenza virus was spreading in Asia and issued a warning that the bird flu could spread from poultry to humans. It urged "heightened readiness and surveillance" as the mutant strain posed "unpredictable risks to human health."But Professor Baggoley, who took office on Tuesday, said Australia is well served by strict testing and customs regimes, adding that avian migration patterns also mean infected birds are highly unlikely to arrive in Australia."I don't think we should be worried," Prof Baggoley told Sky News."The country and the Australian government is certainly vigilant in relation to bird flu."Prof. Baggoley insisted the H5N1 virus remains overwhelmingly a disease of birds and it is very uncommon for humans to catch it. It is also exceedingly rare for humans to spread it among themselves.He said that even if bird flu did arrive and affected humans, Australia is ready to respond to any new and significant developments in bird flu."Australia tests migratory wild birds, looking for H5N1, and has been doing this for some years and has never found it," he said."On the human side of things, Australia has been preparing for a possible outbreak of H5N1 since 2004."We've got the laboratory capacity to diagnose influenza; we've got arrangements in place for a rapid production of an H5N1 vaccine for humans, and we've got ready access to antivirals."There have been no outbreaks of bird flu in Australia to date.The UN said the latest human death from bird flu occurred earlier this month in Cambodia, which has registered eight cases of human infection this year, all of them fatal.H5N1 has infected 565 people since it first appeared in 2003, killing 331.

PARIS, Aug. 7 (Xinhua) -- European heavy-lift launcher Ariane 5 lifted off two communication satellites on Saturday.The Ariane 5, carrying Astra 1N and BSAT-3c/JCSAT-110R, was launched at 2252 GMT on Saturday from Kourou launch centre in French Guiana, according to live broadcast of the launching process.This was the fourth mission of Ariane 5 in 2011 and its 203th flight that sent off the two satellites Saturday night to their respective geostationary transfer orbits.Astra 1N, to be separated first, is built by EADS Astrium in Toulouse, France, for the Luxembourg-based operator SES Astra. With a designed lifespan of 15 years, it has an estimated liftoff mass of 5,350 kg and is fitted with 52 active Ku-band transponders.It is initially to deliver interim capacity from an orbital position of 28.2 degree East, and will subsequently move to SES Astra's prime location at 19.2 degree East for primary and backup services.BSAT-3c/JCSAT-110R is manufactured by Lockheed Martin Commercial Space Systems in Newtown, Pennsylvania, for Japanese operators B-SAT Corporation and SKY Perfect JSAT Corporation. This satellite weighs approximately 2,910 kg at launch time. It is to be positioned at 110 degree East longitude in geostationary orbit with a lifetime exceeding 16 years.This Ariane 5 flight has been postponed twice, firstly due to some technical problem in early July and then delayed by bad weather.Arianespace plans to achieve six Ariane 5 missions through this year.

WELLINGTON, May 31 (Xinhua) -- New Zealand agricultural produce regulators cleared an Auckland-based firm that exported infant formula to China of food safety concerns, just hours after confirming they had launched an investigation.The clarification came the same day Kiaora New Zealand International, marketers of Heitiki infant formula, apologized for using a Maori name and icon on its product packaging.The Ministry of Agriculture and Forestry (MAF) issued a statement Tuesday to say Kiaora New Zealand had been cleared of food safety and export regulations concerns, but an investigation into the labeling and marketing of Heitiki would continue.The MAF issued a statement earlier Tuesday confirming reports it was investigating the product's safety, but MAF compliance and enforcement director Geoff Allen said in a later statement the investigation had been underway for about 10 days."The investigation was triggered by our internal surveillance. The investigation was primarily on whether there was a food safety issue, and I'm pleased to report that no food safety issues were identified," said Allen.Nothing "untoward" was identified in the origin and export destination of Heitiki-branded products, which were manufactured in New Zealand according to legal requirements, said Allen."The investigation has now turned to the labeling and marketing of the product. This aspect is ongoing, and seeks to identify anything in the labeling or marketing that is inaccurate or misleading.
