BEIJING, May 4 (Xinhuanet) -- No formalin has been found in the milk powder imported from S. Korea into China due to different milk sources, the general agency of South Korea's Maeil Dairies said Tuesday.The declaration came after Maeil Dairies, South Korea's third-largest dairy company, was found to have produced milk from cows given feed tainted with formalin.The agency said that the milk used in the dairy products exported to China comes from New Zealand, Europe and other places outside South Korea, so Chinese consumers should have nothing to worry about.Formalin, a liquid form of formaldehyde gas, was largely used in the past as a disinfectant, pesticide and bactericide for preservation of biological specimens.Its use has dwindled over the years due to health concerns.After the incident, South Korea has decided to conduct emergency inspections on milk sold in the market by four major dairy companies, to check the presence of formalin.

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Baojing, a senior official with the National Office for S&T Award, told Xinhua it was the first time China had withdrawn a national scientific honor.The revocation soon sparked pubic discussion over academic integrity.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."

MOSCOW, Jan. 24 (Xinhua) -- Russian President Dmitry Medvedev and visiting Chinese State Councilor Dai Bingguo held talks here on Monday, discussing prospects for the development of cooperation between the two countries.Medvedev and Dai Bingguo discussed the development of Russian- Chinese bilateral cooperation and interaction on the international arena.The Russian president said the Sino-Russian strategic partnership of coordination is developing further in all aspects, as the leaders of the two nations kept close contact during last year and cooperation in the economic and trade sphere has been deepened.Russia sees China as its closest partner, a position that will never be changed, Medvedev stressed.Russia is willing to work together with China to promote all- around cooperation and coordination on international and regional issues, Medvedev said.He said the strategic security talks between Russia and China, a major goal of Dai's current visit, have served as an important channel for bilateral coordination and exchanges, and played a pivotal role in enhancing bilateral strategic mutual trust.Dai Bingguo, who arrived in Moscow Sunday for a three-day visit, said that the first ten years of the 21st century had been important for Sino-Russian relations.China attaches great importance to the strategic coordination with Russia and is willing to work with Russia to develop their strategic partnership of coordination at a higher stage, the Chinese state councilor said.

BEIJING, March 24 (Xinhuanet) -- Mozilla's newly launched Firefox 4 Web browser was downloaded nearly 7 million times worldwide in the first 24 hours, according to media reports.The number was almost triple the 2.4 million downloads that Microsoft reported in the first 24 hours after the Internet Explorer 9 (IE9) was released.Nevertheless, the number lagged behind the record-breaking performance of Firefox 3, which was downloaded more than 8 million times in the first day after launch in mid-2008.Statistics show that Firefox 4 has attracted interest from around the world, with 44 percent downloads in Europe, 26 percent in North America. and 20 percent in Asia.Mozilla launched Firefox 4 on Tuesday at around 10:00 a.m. EDT to compete with Microsoft's IE9 and Google Chrome.The new Web browser was originally scheduled to ship last November, but bugs delayed the release into early this year.Firefox trumped IE9 in the first day download contest because it runs on Windows XP, the 10-year-old operating system that IE9 doesn't support.

The type-4 dengue fever is not more dangerous than the other types, but as the disease had not been registered in the region before, the local population has no immunity to it.As there are four different types of dengue fever, a person can develop the disease several times.The last epidemic of dengue fever in Rio de Janeiro state occurred in 2008 when 174 people died of the disease and some 250,000 cases of dengue were registered.
