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, Sep. 16 (Xinhuanet) -- Government incentives are important to pave a low-carbon road to economic growth, but companies that improve their industry models and technologies are the main players and also benefit receivers, noted officials and industry insiders at the Summer Davos forum held in Dalian on Sep 14."The most important thing is to have the right direction," said Gao Jifan, chairman and CEO of Trina Solar, a national leading solar panel manufacturer in China.According to Gao, new energy solutions such as solar power, is the "right direction" of future growth, although many deficiencies still exist today. "As long as we have the direction correct, we can succeed as last. But this also requires policies, technologies and investment," he said.Malini Mehra, founder and CEO of the Centre for Social Markets, a non-profit organization that promotes sustainability, said there are two ways in which the governments can support low-carbon businesses to continue along a "green" path."The first is to provide some means of recognizing their good work," she said. And the second is building a measuring system to "verify which company is actually doing well, not just talking about doing well".Preferential policies are only the foundation, said Gao. "We must have a good overall plan along with advanced technologies to bring value back to the investors."Gao envisions that most of the world’s families will have "zero-consumption" houses with energy supply and storage systems relying purely on solar power by 2020.Without grid limitations, the technology can be used everywhere in the world, especially in the less developed areas."The cost of solar technologies has been on the decline over the past few years because of policy incentives and innovations of companies around the world," said Gao.A solar panel producing one watt’s electricity cost in 2005, but now it is reduced to only .2 to .3, he explained."This is the result of technological innovations and large-scale manufacturing. And it makes us more confident to see the solar energy to become a major part of the energy system in the future."Being low-carbon also helps a company attract clients because it is the current fashion and customers are more likely to choose low-carbon products, noted Klaus Kleifeld, CEO of the US aluminum products maker Alcoa Inc."The generation that we recruit today has a very different social consciousness and standards," he said. "They want to see and only want to work for companies that are sustainable."

LOS ANGELES, June 23 (Xinhua) -- The sun and its inner planets may have formed differently than previously thought, NASA's Jet Propulsion Laboratory (JPL) said on Thursday.Data revealed differences between the sun and planets in oxygen and nitrogen, which are two of the most abundant elements in our solar system, said JPL in Pasadena, Los Angeles.Although the difference is slight, the implications could help determine how our solar system evolved, JPL said.NASA researchers drew the conclusion after analyzing samples returned by NASA's 2004 Genesis mission, according to JPL.The air on Earth contains three different kinds of oxygen atoms which are differentiated by the number of neutrons they contain. Nearly 100 percent of oxygen atoms in the solar system are composed of O-16, but there are also tiny amounts of more exotic oxygen isotopes called O-17 and O-18. Researchers studying the oxygen of Genesis samples found that the percentage of O-16 in the sun is slightly higher than on Earth or on other terrestrial planets. The other isotopes' percentages were slightly lower."We found that Earth, the moon, as well as Martian and other meteorites which are samples of asteroids, have a lower concentration of the O-16 than does the sun," said Kevin McKeegan, a Genesis co-investigator from University of California, Los Angeles (UCLA) and the lead author of one of two papers published this week in Science journal. "The implication is that we did not form out of the same solar nebula materials that created the sun -- just how and why remains to be discovered." Another paper detailed differences between the sun and planets in the element nitrogen. Like oxygen, nitrogen has one isotope, N- 14, that makes up nearly 100 percent of the atoms in the solar system, but there is also a tiny amount of N-15. Researchers studying the same samples saw that when compared to Earth's atmosphere, nitrogen in the sun and Jupiter has slightly more N-14, but 40 percent less N-15. Both the sun and Jupiter appear to have the same nitrogen composition. As is the case for oxygen, Earth and the rest of the inner solar system are very different in nitrogen."These findings show that all solar system objects including the terrestrial planets, meteorites and comets are anomalous compared to the initial composition of the nebula from which the solar system formed," said Bernard Marty, a Genesis co- investigator from Petrographic and Geochemical Research Center in Fracne and the lead author of the other new Science paper. " Understanding the cause of such a heterogeneity will impact our view on the formation of the solar system."Data were obtained from analysis of samples Genesis collected from the solar wind, or material ejected from the outer portion of the sun. This material can be thought of as a fossil of our nebula because the preponderance of scientific evidence suggests that the outer layer of our sun has not changed measurably for billions of years."The sun houses more than 99 percent of the material currently in our solar system, so it's a good idea to get to know it better, " said Genesis Principal Investigator Don Burnett of the California Institute of Technology, Pasadena, California. "While it was more challenging than expected, we have answered some important questions, and like all successful missions, generated plenty more."Genesis was launched in August 2000. The spacecraft traveled to Earth's L1 Lagrange Point about one million miles from Earth, where it remained for 886 days between 2001 and 2004, passively collecting solar-wind samples.JPL managed the Genesis mission for NASA's Science Mission Directorate, Washington. The Genesis mission was part of the Discovery Program managed at NASA's Marshall Space Flight Center in Huntsville, Alasca.

BERLIN, Aug. 28 (Xinhua) -- Mercedes-Benz, the world leading luxury car producer, celebrates the 125th anniversary of its invention of automobile with what it claimed the largest gathering ever, at the former Tempelhof airport in Berlin on the weekend.The Mercedes-Benz Club and Mercedes-Benz enthusiasts greet visitors with some 1,800 well-assorted Mercedes-Benz-branded vehicles, ranging from vintage and classic passenger cars to a variety of historic commercial vehicles, on a vast open areas of 250,000 square metres of the abandoned Tempelhof airport, which was closed in 2008.It took Mr. Lauritzen and his wife two days' drive of their cherised wecker of Mercedes-Benz Cabriolet B. 320.W 142.-3,4l to reach here for taking part in the pageant."It is a long journey, but we are happy to be here to see more class cars and more friends with same interests," Mrs Lauritzen said.Owners take the opportunity to present their lovingly cared-for vehicles, which include a number of truly rare items of automotive history, to the Berlin public.The couple of Mr. Kerner drove their red Mercedes-Benz 170Dba, a made-in-1952 model with a range of special and unique designs which are very rarely seen now, over journey of 155 km from Bitterfeld to join in the gala."I'm fond of driving my classic car of Benz," said Mrs Kerner, despite it can run maximally at a speed of 50 to 80 km per hour, "but I truly enjoy the diesel engine sounds and the historic feeling it evokes."The legendary Silver Arrows, dating from the 1930s and 1950s, are also presented from the Mercedes-Benz Classic collection for demonstration drives."The brilliant history of the Silver Arrows will be brought to life with a demonstration of their impressive engine sound and incredible driving dynamics," said Michael Bock, head of Mercedes-Benz Classic and Director of Mercedes-Benz Museum GmbH."It is not often that these racing cars are driven in public, so this will be a true highlight of the program of events in Tempelhof."During the grand show, visitors are also accessible to first-hand experiences of the latest technologies applicable in the future for in passenger cars, commercial vehicles and racing cars."Some 125 years ago, Carl Benz submitted his patent application for the Benz Patent Motor Car to the Patent Office in Berlin", the organizer appealed to the visitors, saying now Mercedes-Benz is returning to Berlin to celebrate together with Berliners.

BEIJING, Aug. 24 (Xinhuanet)-- A new study shows that a diet rich in cholesterol-friendly foods, such as soy products and tree nuts, can decrease LDL (bad) cholesterol significantly, according to media reports on Tuesday.The study, published in the Journal of the American Medical Association, found that people who ate a healthy diet filled with cholesterol-lowering foods experienced a 13 percent decrease in their LDL cholesterol levels.For patients with high levels of so-called bad cholesterol, doctors usually have two prescriptions: cholesterol-lowering statin drugs and a diet that cuts out foods high in saturated fat, such as ice cream, red meat and butter.But the new study found that when it comes to lowering artery-clogging cholesterol, what you eat may be more important than what you don't eat.David Jenkins of St. Michael's Hospital and the University created the "portfolio diet," which includes regular consumption of tree nuts and high amounts of fiber from oats, barley and vegetables. The diet, which replaces butter with plant sterol-enriched margarine and substitute soy-based products for meat, allows maximum benefit in lowering cholesterol and preventing heart disease. "The study highlighted the power of food to lower risk for cardiovascular disease: What you do eat and what you don't eat are both important," said Dr. Jane Klauer, a New York internist specializing in metabolism and nutrition.A high overall cholesterol level makes a person nearly twice as likely to suffer a heart attack or stroke as someone whose total cholesterol falls into a healthy range.
