BEIJING, Feb. 12 (Xinhua) -- China's recent revocation of a national scientific award due to academic fraud has been welcomed by the public, but experts warn the country still has a long way to go to bring an end to such dubious academic practices.On Feb. 1, China's Ministry of Science and Technology, revoked the State Scientific and Technological Progress Award (SSTPA) given to Li Liansheng, former professor of Xi'an Jiaotong University in 2005.An investigation found Li had plagiarized others' works and fabricated data in his winning project, a research on key technologies for designing and manufacturing scroll compressors. Li was investigated after the science ministry received tip-offs from six professors (including four retired) in his university.The ministry subsequently canceled his prize and retrieved the money awarded.Zhao Baojing, a senior official with the National Office for S&T Award, told Xinhua it was the first time China had withdrawn a national scientific honor.The revocation soon sparked pubic discussion over academic integrity. Tan Gang, a citizen in Shenzhen, wrote on his microblog, "Though the revocation came a bit late, it is progress. It's a warning against academic misconduct."Shi Ying, vice director of Shanxi Academy of Social Sciences, said, the move demonstrated China's "zero-tolerance" for academic fraud, and would help clean up the academic field."However, academic fraud is still rampant, which not only damages academic integrity, but also harms the innovative capacity of China in a broader sense," said Shi.Anti-fraud activist Fang Zhouzi, who runs a website on anti-academic fraud from his Beijing home, said "This is by far the harshest stance China has ever taken against academic fraud, which should be viewed as progress." He so noted China still has a long way to go in the fight against academic fraud.Fang said, the science ministry's move does not mean China is really cracking down on academic fraud. The plagiarist might have not been found out if it were not for years of unyielding efforts made by the six professors.The scandal again highlights that academic fraud is alive and well in China. A survey conducted among 30,078 respondents in 2009 by the China Association for Science and Technology (CAST) showed that nearly half of the science-related workers in China's research institutes, universities, medical institutes and hospitals think academic cheating is "common."Fang attributed the prevalence of academic fraud in China to lax punishments and loopholes in the academic evaluation system.Zero tolerance of academic fraudChina's science minister, Wan Gang, said on several occasions "We hold zero tolerance for academic fraud."However, Fang said "zero tolerance" was a slogan rather than the actual case. Many cases of academic fraud, even publicly exposed, were "tolerated" eventually. "Lax punishment makes academic fraud less costly."

WASHINGTON, April 25 (Xinhua) -- The U.S. National Aeronautics and Space Administration (NASA) and the U.S. Agency for International Development (USAID) have agreed to expand their joint efforts to overcome international development challenges such as food security, climate change, and energy and environmental management.NASA Administrator Charles Bolden and USAID Administrator Rajiv Shah signed a five-year memorandum of understanding on Monday, at NASA Headquarters. The agreement formalizes ongoing agency collaborations that use Earth science data to address developmental challenges, and to assist in disaster mitigation and humanitarian responses. The agreement also encourages NASA and USAID to apply geospatial technologies to solve development challenges affecting the United States and developing countries."Technologies for NASA missions have long improved life here on Earth. Together with USAID, we'll meet even more sustainable development challenges here on the ground, solving problems for the world community," Bolden said in a statement. "As we explore space, we'll also be exploring solutions to important health, nutritional and safety challenges in developing countries."The agencies will continue collaborations to stimulate innovative science and technology solutions to international development challenges by using Earth science data, research results, computer models, visualization applications and remote- sensing techniques.USAID is the lead federal development agency implementing U.S. development efforts through field-based programs and projects around the world. NASA has broad experience with Earth science research, development of Earth science information products, and technology applications."Through our partnership with NASA, we can apply the latest, cutting-edge technology to deliver meaningful results for people in developing countries in areas like health, food security and water," Shah said. "It's a prime example of our efforts to use the power of science and technology to tackle today's pressing development challenges."Since 2003, NASA and USAID have worked together building and expanding the SERVIR program, which allows people in developing regions to use Earth observations for addressing challenges in agriculture, biodiversity conservation, climate change, disaster response, weather forecasting, and energy and health issues.The agencies also collaborate on the LAUNCH program, which supports science and technology innovators in the nonprofit and private sectors. The program's goal is improving innovations to achieve greater impact on sustainability issues.

BEIJING, Feb. 10 (Xinhua) -- First snow fell in Beijing Wednesday night and continued into Thursday morning. It was the latest first snow for the city in 60 years.Beijing has had no precipitation for 108 consecutive days this winter.Local meteorologists said from 8:00 Wednesday to 6:00 Thursday, precipitation in Beijing averaged 1 mm."Now there is snow at last. I love the taste of snow." "The world in pure white! It's the most beautiful landscape in winter." Beijing residents who stayed late in the night and happened to see the first flakes of snow in the city left their postings on microblogs.However, meteorologists said the first snow won't last long and it will end on Thursday noon. In midnight, the city will have a cloudy weather, and Friday will be a sunny day."As the precipitation is small, it will have limited effect on easing drought," Song Jisong, the municipal meteorological bureau's chief weather forecaster said.Sun said that the capital city's record-long winter drought occurred in the winter of 1970/71, when there was no precipitation for 114 days. This winter drought was the second longest in 60 years.Meteorologists said the current snowfall will reduce risks of fire.The snow also affected the city's traffic. Local traffic control authorities estimated that there were more than 40 highways on which vehicles ran at a speed lower than 20 km per hour in the rush hour Thursday morning.The authorities said an emergency headquarters had been set up for the snow weather. Expressways connecting Beijing with Chengde, Tianjin and Tibet will likely have some sections closed for the time being.A spokesperson with the Beijing Capital International Airport Co., Ltd. said that by 6:00 a.m. Thursday, runways at the airport had operated normally, and take-offs and landings had been normal, with no flights delayed.The airport has also launched an emergency scheme. At last 64 ice removal vehicles had been arranged to ensure the normal operaton of flights.Wednesday also saw snowfall and sleet in Gansu, Shaanxi, Shanxi, Henan and Anhui provinces and rainfall in the Yellow River and Huaihe River valleys, southwestern regions and the middle-and-lower reaches of the Yangtze River valley. And snow and rainfall will continue in the those areas Thursday.

BEIJING, May 11 (Xinhuanet) -- New retirees suddenly confronted with plenty of time on their hands might be happy to learn that reading keeps one mentally alert and abreast of current aff airs, says Ursula Lenz of Germany's working group of senior citizens' organizations, BAGSO.Growing old can present difficulties such as failing eyesight or problems concentrating, but experts encourage the elderly not to give up on reading and to adapt to their situation.From the perspective of health professionals, there are many advantages to reading books or newspapers for senior citizens.Reading helps the elderly keep a sharp mind. The ability to transform words into mental images is good for cognitive performance. Reading also improves vocabulary, language use and the ability to concentrate, according to Simone Helck from the Kuratorium Deutsche Altershilfe, an organization in Germany that helps promote and develop strategies for taking care of the elderly.So, what exactly happens in the brain when we read?"The brain builds new synapses, junctions between the neurons, when it's stimulated such as during reading," says Manfred Gogol, a physician and president of Germany's Society for Gerontology and Geriatrics.Gogol recommends reading books that deal with subjects that are of special interest to the reader. If a long novel seems like too much work, then try a novella or collection of short stories.But a prerequisite for reading is that any sight defect is corrected by an optician.In response to the needs of elderly people, publishers print books with large typefaces and bigger line spacing. Lenz says it is worthwhile asking for large print books in libraries and bookshops.But no matter what the reading matter is, another important aspect is being able to exchange opinions about a book with other people. Whether it's a society magazine, highbrow literature or a daily newspaper, there is always something to talk about.

BEIJING, Feb. 5 (Xinhua) -- China's meteorological authority said Saturday that a cold snap would sweep north China over the next few days, bringing down temperatures and carrying gusty winds.Temperatures in some parts of Xinjiang Uygur Autonomous Region, Inner Mongolia Autonomous Region and northeast China will drop 4 to 6 degrees Celsius over the weekend, the National Meteorological Center (NMC) said in a statement on its website.In most areas north to the Huaihe River, the temperatures will go down 4 to 6 degrees Celsius, or even 8 to 10 degrees Celsius in some parts of the areas between Monday and Tuesday.The cold front would then move southward to affect more areas in the eastern and southern parts of the country.The NMC said some areas in northern and western Xinjiang Uygur Autonomous Region, the eastern part of Inner Mongolia, Sichuan Basin and most of the northeast China, the western parts of the areas south to the Yangtze River will see light to moderate snow or sleet in the forthcoming three days.Fog continued to shroud south China Saturday, reducing visibility to less than 200 meters in parts of Hunan, Hubei, Jiangxi, Sichuan and Fujian provinces, as well as Chongqing City.
