WELLINGTON, May 27 (Xinhua) -- Eating kiwifruit might be a much better way of getting vitamin C into your system than taking purified vitamin supplements, according to research from New Zealand.Researchers with the University of Otago found that in mice eating kiwifruit, vitamin C uptake was five times as effective as taking a purified supplement form.The study was published in the American Journal of Clinical Nutrition, the highest ranking journal for human nutrition research, said a statement from the university.Lead researcher Associate Professor Margreet Vissers said people required vitamin C (ascorbate) in all body tissues and organs to be healthy, but the only source of vitamin C was through food or in purified form, arguably the most commonly consumed vitamin supplement.In the experiment vitamin C-deficient mice were fed the vitamin over a month, either as kiwifruit or as an equivalent amount of pure vitamin C, said the statement.Mice fed the kiwifruit absorbed vitamin C much more efficiently than those given the purified supplement form, and they also retained it for longer, indicating something in the fruit improved absorption and retention."The findings of the mouse trial have important implications for human nutrition," said Vissers."The question that has often been asked is whether a supplement is as good a source of vitamin C as whole foods, but few studies have addressed this issue. We are uniquely placed to do that work. "An equivalent human study was underway to determine whether the situation also applied to people, said the statement.The mouse study was funded by the university and kiwifruit marketing firm Zespri.
BEIJING, Jan. 30 (Xinhua) -- As of Jan. 28, 77.4 million mu (5.16 million acres) of crops had been harmed by the ongoing drought, and 2.57 million people were faced with drinking water shortages in China, the national drought control authorities said Sunday.Local governments of the affected regions must make efforts to monitor drought conditions, speed up the building of water projects, increase drought-fighting material reserves and grant subsidies to the drought-stricken population, said officials at a meeting attended by Chen Lei, deputy head of the Office of State Flood Control and Drought Relief Headquarters (SFDH).The National Meteorological Center (NMC) forecast the drought to worsen in the next two months, saying Sunday that the drought-hit north China and regions along the Yellow and Huaihe rivers would receive little rain or snow in February and March.Chen, also minister of water resources, stressed the importance of drought relief efforts, guaranteeing agricultural production and ensuring drinking water safety for boosting consumers' confidence, controlling consumer prices and inflation and maintaining economic growth.Since last Autumn when the drought began, local authorities have assigned 9.55 million people and 2.15 million sets of drought-fighting machineries to draw 8.2 billion cubic meters of water to irrigate 110 million mu of crop land.
LOS ANGELES, April 7 (Xinhua) -- Using NASA's Galaxy Evolution Explorer (GEE) satellite, U.S. astronomers are hunting for nearby, hard-to-see stars which could very well be home to the easiest-to-see alien planets, it was announced on Thursday.U.S. astronomers are ferreting out the new targets after the glare of bright, shining stars has frustrated most efforts at visualizing distant worlds, NASA's Jet Propulsion Laboratory (JPL) said.So far, only a handful of distant planets, or exoplanets, have been directly imaged. Small, newborn stars are less blinding, making the planets easier to see, but the fact that these stars are dim means they are hard to find in the first place."Fortunately, the young stars emit more ultraviolet light than their older counterparts, which makes them conspicuous to the ultraviolet-detecting GEE," JPL said in a press release."We've discovered a new technique of using ultraviolet light to search for young, low-mass stars near the Earth," said David Rodriguez, a graduate student of astronomy at University of Californian, Los Angeles. "These young stars make excellent targets for future direct imaging of exoplanets."Young stars, like human children, tend to be a bit unruly -- they spout a greater proportion of energetic X-rays and ultraviolet light than more mature stars. In some cases, X-ray surveys can pick out these youngsters due to the "racket" they cause. However, many smaller, less "noisy" baby stars perfect for exoplanet imaging studies have gone undetected except in the most detailed X-ray surveys. To date, such surveys have covered only a small percentage of the sky, according to JPL in Pasadena, Los Angeles.Rodriguez and his team figured that the GEE, which has scanned about three-quarters of the sky in ultraviolet light, could fill this gap.Astronomers compared readings from the telescope with optical and infrared data to look for the telltale signature of rambunctious junior stars. Follow-up observations of 24 candidates identified in this manner determined that 17 of the stars showed clear signs of youth, validating the team's approach, JPL said."The Galaxy Evolution Explorer can readily select young, low- mass stars that are too faint to turn up in all-sky X-ray surveys, which makes the telescope an incredibly useful tool," Rodriguez said in the release.
BEIJING, Feb. 15 (Xinhua) -- China's consumer inflation accelerated in January on surging food prices, adding pressure for the government to tackle escalating inflation amid the nation's spreading winter drought.The consumer price index (CPI), a main gauge of inflation, rose 4.9 percent in January year on year, the National Bureau of Statistics (NBS) announced Tuesday.The figure is 0.3 percentage points higher than that of December.Food prices soared 10.3 percent year on year.
BEIJING, May 16 (Xinhua) -- An initial ruling by China's Ministry of Commerce said Monday that European Union (EU) members have subsidized potato starch exports to China, hurting the interests of China's domestic industries.China will impose an anti-subsidy provision of the tariff on potato starch products effective from May 19, the ministry said in a statement on its website. The rate will range between 7.7 percent and 11.19 percent, depending on the subsidy margin, according to the statement.The initial ruling accused several EU companies, including France's Roquette Freres and Netherland's AVEBE, of receiving subsidies.China launched an anti-subsidy investigation into potato starch imports from the EU on August 30, 2010 at the request of the China Starch Industry Association. This was China's first-ever anti-subsidy probe into imports from the EU.China had earlier decided to impose anti-dumping tariffs ranging from 12.6 percent to 56.7 percent on EU potato starch products. The new tariffs were effective from April 19.
