BEIJING, Jan. 26 (Xinhua) -- China remained a major victim of trade protectionism during the past year, witnessing 64 trade disputes in this period, covering some 7 billion U.S. dollars in value, China's Vice Commerce Minister, Zhong Shan, said here Wednesday.The country faced trade disputes with both developed countries and developing ones, which came from not only traditional sectors but also high-tech industries, he told a national conference on trade promotion.For the short- and mid-term, China would work to maintain a stable growth in foreign trade and keep the growth rate higher than both the global level and China's economic growth, he said.China would also strive to achieve a more balanced trade structure by boosting imports and outbound investment, to strengthen the quality and efficiency of foreign trade, he added.China's foreign trade last year jumped 34.7 percent year on year to more than 2.97 trillion U.S. dollars, while its trade surplus fell 6.4 percent to 183.1 billion U.S. dollars.

CANBERRA, May 27 (Xinhua) -- An Australian student has discovered a part of the universe that astrophysicists have spent decades trying to find, Australia's Monash University on Friday confirmed in a statement.Astrophysicists have long thought the universe has a greater mass than is visible in the planets, but they had no way of proving it is there.Undergraduate student Amelia Fraser-McKelvie, 22, was on a summer internship at Monash University to learn more about astrophysics, when she managed to solve one of the big mysteries of science.Fraser-McKelvie, an aerospace engineering student, conducted a targeted X-ray search for the matter and found evidence of it within three months.Her tutor, Kevin Pimbblet, said the discovery is significant."We've been looking for this ordinary matter for a couple of decades," he said in a statement on Friday."It's been published in one of the most prestigious journals in the world, so astronomers all over the world will be able to read this article."Scientists had thought the matter would have a temperature of about 1 million degrees Celsius, 1.8 million degrees Fahrenheit, and should therefore be observable at X-ray wavelengths.Amelia Fraser-McKelvie's discovery has proved that prediction is correct, Pimbblet said.The trio published a research paper on the missing mass in one of the world's oldest and most prestigious scientific journals, Monthly Notices of the Royal Astronomical Society.He said the discovery could change the way telescopes are built.

  

BEIJING, March 19 (Xinhua) -- Radiation leaks following explosions at the Fukushima Daiichi nuclear power plant in Japan will not affect China's environment and the health of its citizens during the next three days, authorities said Saturday.China's National Nuclear Emergency Coordination Committee made the announcement based upon analyses of environmental monitoring, meteorological forecasts, and ocean currents.The Beijing-based Regional Specialized Meteorological Center, which is affiliated with the World Meteorological Organization, issued its forecast on Saturday afternoon, saying that the radioactive leakages in Japan would not affect China over the next three days.The country's State Oceanic Administration on Saturday announced that no abnormalities were detected in terms of atmospheric radiation over the East China Sea, the northern part of the South China Sea, and the central and northern regions of the Yellow Sea.The administration predicts that the ocean currents near Fukushima would mainly travel eastward from Japan over the next three days.Furthermore, the country's Ministry of Environmental Protection announced that China's environment remains normal based upon the monitoring of radiation levels.

  

CANBERRA, May 10 (Xinhua) -- Technology may have a harmful effect on children's development and creativity, Australia's report found on Tuesday.The Pilot Pen Australia Creativity Report found that children could be depending too much on technology such as computers.Written by psychologist Kimberley O'Brien, the report suggested that students are becoming scared of handwritten tasks as there is no spelling or grammar check tool to pick up their mistakes as they go along."Children who develop this kind of dependency on computer software are less likely to write using a pen and paper given that they will feel a vulnerability to failure," the report said.It said using software that immediately tells children to correct errors like spelling and grammar could disrupts their thought patterns and stunts their ideas, and children who hand write are able to produce almost twice as many ideas as those using computer technology to write a creative story.The report studied 300 Year five and six children, and found handwritten essays were completed significantly faster and contained a higher standard of sentence structure, grammar, punctuation, cohesion, ideas development and organization than those completed using keyboards.A further study found students in Years two, four and six produced up to twice as many ideas writing on pen and paper as those on computers.O'Brien said the results were due to computers putting extra pressure on writers to edit as they go rather than get their ideas down first and edit minor mistakes later.O'Brien said children were most likely to develop their handwriting skills between the ages of eight and 10, and she urged all teachers and parents to ensure their children met community standards for legible handwriting.However, she said that computers are a good support tool, and they should not replace handwriting entirely.
