BEIJING, Oct. 3 (Xinhuanet) -- Ziqian (not his real name, but an avatar he uses online) is in Paris working on his master's degree, but he stays in close touch with his contacts in China through Sina Corp's Weibo, a micro blog platform. It was a pleasant way to keep up with acquaintances. But that all changed when Ziqian quoted a blog post from an alumnus of his alma mater, Nanjing University, on July 5. It said the school did not organize students to sing Red songs ahead of July 1, the 90th anniversary of the founding of the Communist Party of China. Ziqian suddenly found himself inundated with comments from enraged bloggers whom he didn't know. He had lost all integrity, they said.Ziqian spent the whole night arguing with one netizen who assailed him with insults. He was left feeling tired and puzzled.He said he would have given up micro-blogging altogether as "purely useless", but he uses it to stay in touch with his girlfriend.Micro-blogging has been growing rapidly, dwarfing the many other forms of social networking that came into being only three or four years ago.Famed for spreading messages almost instantly and supervising the doings of agencies and organizations, micro blogs have already won some notable battles.In March, micro-bloggers persuaded the city of Nanjing, Jiangsu province, to spare 600 old trees that were to be cut down; they also organized assistance to earthquake victims in Japan.In July, they brought the Red Cross Society of China and other philanthropies under scrutiny.But, like everything in life, there is also a downside to micro-blogging.In the Weibo-dominated virtual world, Ziqian's experience has proved a common occurrence. A 28-year-old woman, surnamed Zhang, who declined to disclose her full name, works at a TV station in Jiangsu province. She recounted her recent encounter with online abusive remarks.After watching a popular talent show, Zhang wrote half-jokingly online - without using her real name - that the program was boring and lacked imagination. Regarding herself as an "industry insider", Zhang believed her reasoning had some objective basis.Nevertheless, she was soon confronted with a wave of criticism, some of it vulgar, saying she had no appreciation for the arts."I was very depressed by the comments. It's like you get kidnapped by mainstream opinion," she said. "I lost the desire to share my views with others.""I respect the freedom of speech doctrine, and everyone is allowed to publicize his or her thoughts," Zhang wrote in a separate post. "But don't hurl random assaults at others and take for granted that whatever you say is truth."Micro blogs have also made some ordinary people famous, though not in the way they would like.Zhang Mingyi, 22, is one such person.After appearing on a dating show on Shanghai-based Dragon TV, she said her micro blog inboxes were filled every day with letters lashing out at her, because of her open enthusiasm for Japanese culture and a failed marriage.Some netizens are relentless in their resentment of her. Even her micro blog followers received warnings to stay away from the "quisling". One such message read: "Go tell her to marry a Japanese man. Don't act so shamelessly in China".Similarly, Guo Meimei, now a household name, said she was being stalked and even threatened in early September, after she bragged in a micro blog post about her wealth and - untruthfully - claimed to hold a position at the Red Cross Society of China.Bloggers launched a vast campaign boycotting a song she released online and an online game she endorsed. They satirized her plastic surgeries and gossiped about her whereabouts. In a recent interview with China Daily, Guo said the animosity she stirred was so intense that she had even considered suicide."I feel like I am an enemy of the state," she said. "The truth is that I am just a stupid girl who did something really stupid. No matter what I do, nobody wants to forgive me."Celebrities are more likely to become the targets of the word-of-mouth maelstrom online. Yang Lan, for instance, a famous TV anchorwoman, came under tremendous pressure as bloggers dug into her connections with China-Africa Hope Project, an organization set up by a prominent philanthropist, Lu Junqing, that became controversial because he empowered his 24-year-old daughter to manage the charity's substantial donated funds.Bloggers questioned whether the purpose of Lu's initiative was charity or cashing in on donators. Rumors held sway on micro blogs.A recent study from University of Michigan suggests that it is crucial that people distinguish between the truth and unfounded rumors in online social media, where vast amounts of information are easily spread across a large network by sources of unverified authority.According to Xie Gengyun, author of the 2010 China Micro Blog Annual Report and deputy dean at the Arts and Humanities Research Institute at Shanghai Jiaotong University, micro blogs can generate and spread unfounded rumors, such as the "Shanxi earthquake" and "Louis Cha's death"."Micro-bloggers are currently the better-educated people in China. But users will soon include those at the grassroots level, and the function of micro blogs will change from celebrity-watching to online socializing and venting about life's disappointments," Xie said.China's Internet, with more registered users than any other nation, is a lively forum for public opinion, said Xinhua News Agency. But "concocting rumors is itself a social malady, and the spread of rumors across the Internet presents a massive social threat."The micro blog platform tends to breed more rumors and assaults than other channels because of the limited amount of characters each post can use, according to Xiong Yihan, a sociologist with Fudan University."The word limit has made it hard to present a balanced and fair opinion. Besides, posts with extreme views are more likely to be forwarded online, because they satisfy people's thirst for the unknown," Xiong said.Xiong said Internet companies should suspend the accounts of users who spread rumors or libelous statements.

BEIJING, Jan. 8 (Xinhua) -- China canceled over one-third of all official ceremonies, seminars and forums last year in a bid to avoid extravagance or corruption in the use of public resources.Some 2,549 such activities proposed by governments or public institutions, or 37.7 percent of the total applications, which were deemed "ceremonial" and "unnecessary," were cut, saving 1.22 billion yuan (about 193.39 million U.S. dollars), said an official statement released Sunday.The statement was issued by the State Council's Office for Rectifying Malpractices, a ministry-level inter-agency supervisory body dedicated to eliminating administrative irregularities and abuse of power in government agencies, public institutions and major service sectors.Last year's inspections focused on activities co-funded by ministries and local governments, the statement said.The Chinese government agreed with the public that the soaring number of official celebrations, seminars and forums would cost plenty of money and manpower and exacerbate corrupt behaviors.In March, the State Council, or China's Cabinet, ordered 98 ministries and ministry-level government organs to make public their budgets and expenditures on official overseas visits, public vehicles and official receptions -- the "three public consumptions" that had triggered widespread public concern.Premier Wen Jiabao also repeatedly urged the country's government agencies to reduce administrative expenses, including cutting the number of meetings and documents printed.Official figures indicate that the country's crackdown on various forms of extravagant spending by officials saved the country 5.7 billion yuan in 2010.A blue book on China's conferences published in November estimated that the total output of the country's conference industry had reached nearly 1 trillion yuan. Companies made up half of this total, while a considerable portion came from the government and public institutions compared to other social organizations.

WASHINGTON, Nov. 7 (Xinhua) -- U.S. researchers have demonstrated for the first time that the brain is a key player in regulating glucose (sugar) metabolism in humans.The findings, published Monday in the online edition of the Journal of Clinical Investigation, suggest that drugs targeting the brain and central nervous system could be a novel approach to treating diabetes."The brain is the body's only organ that needs a constant supply of glucose to survive, so it makes sense that it would have some say over how much glucose is produced," said study leader Meredith Hawkins, professor of medicine and director of the Global Diabetes Initiative at Yeshiva University, in a statement. "This role for the brain was demonstrated in earlier studies in rodents, but there was considerable controversy over whether the results could be applied to humans. We hope this study helps to settle the matter."In an earlier study in rodents, researchers showed that activation of potassium channels in the brain's hypothalamus sends signals to the liver that dampen its production of glucose. Those findings, published in Nature in 2005, challenged the conventional thinking that blood sugar production by the liver (the body's glucose factory) is regulated only by the pancreas (which makes insulin to metabolize glucose). But carefully performed studies on dogs, conducted at Vanderbilt University, failed to replicate the results, suggesting the Einstein findings in rodents might not be relevant to higher mammals, including humans.The current study, involving people, was aimed at resolving this controversy. Ten nondiabetic subjects were given oral diazoxide, a drug that activates potassium channels in the hypothalamus. (The drug is not used to treat diabetes.) Hormone secretion by the pancreas was controlled to ensure that any change in sugar production would only have occurred through the drug's effect on the brain. After the researchers administered the drug, blood tests revealed that patients' livers were producing significantly less glucose than before.Hawkins and her team then repeated this in rats, again giving diazoxide orally, achieving similar results. They confirmed that sufficient amounts of diazoxide crossed the blood-brain barrier to affect potassium channels in the hypothalamus. Additional experiments confirmed that diazoxide was working through the brain. Specifically, the researchers were able to completely block the effects of diazoxide by infusing a specific potassium channel blocker directly into the brain."This study confirms that the brain plays a significant role in regulating glucose production by the liver," said lead author Preeti Kishore, assistant professor of medicine. "We are now investigating whether this 'brain-to-liver' pathway is impaired in people with diabetes. If so, we may be able to restore normal glucose regulation by targeting potassium channels in the brain."

BEIJING, Jan. 21 (Xinhua) -- A locomotive producer in central China's Hunan province on Friday rolled out a low-cost magnetically levitated (maglev) train that is more environmental-friendly than conventional ones.The three-carriage train is designed to run at a maximum speed of 100 km per hour and carry 600 passengers, said Xu Zongxiang, general manager of Zhuzhou Electric Locomotive Co. Ltd. of China South Locomotive and Rolling Stock Corporation (CSR). Xu said the new train was much quieter than conventional ones. While a conventional train moves forward by using friction between its wheels and the railway tracks, the maglev train replaces wheels by electromagnets and levitates on the guideway. According to Xu, his company's has minimized the risk of the new maglev train derailing or overturning. "It's ideal for mass transportation, as it is quiet and environmental-friendly. Its manufacturing cost is about 75 percent of a conventional light-rail train," said Xu. The maglev train has a minimum turning radius of 50 meters and can easily run in residential communities or on hilly slopes. "It's an ideal public transport option for Chinese cities and major tourist destinations," said Xu. Railway transport specialist Liu Youmei, also an academician with Chinese Academy of Engineering, said the new train is green, economical and safe. "It can be used for public transport in populous areas and at scenic spots with fragile environments." Liu said China is one of a few countries that have applied maglev technology. Beijing is building a maglev route, the Daitai line (S1), which starts at its IT center in Haidian district, passes through Shijingshan district, and ends in Mentougou district on its western outskirts. The line will be operational next year.The eastern metropolitan of Shanghai runs the world's first commercial maglev system on a 30-km stretch between the downtown business district and Pudong airport. The German-made maglev went into operation on Dec. 31, 2002.
