BEIJING, Aug. 24 (Xinhuanet) -- Facebook said it is overhauling its privacy settings to give members easier, more precise control over who sees posts, photos and other content over the vast social network.Starting Thursday, Facebook is rolling out new privacy tools that are placed with each piece of content, replacing options that are now buried in overall account settings.Privacy has been a consistently sticky problem for the Palo Alto firm, which has felt the heat from privacy advocates and government regulators. And recently, Facebook faced stiffer competition from Google's new Google+ social network, which was hailed for including a "circles" feature with easy-to-use privacy settings.Instead of vague labels such as "everyone," which have been mistaken for a Facebook member's social network instead of anyone on the Internet, the new system will include more precise words such as "public.""You have told us that 'who can see this?' could be clearer across Facebook, so we have made changes to make this more visual and straightforward," Chris Cox, Facebook's vice president of product, said in blog post."The main change is moving most of your controls from a settings page to being inline, right next to the posts, photos and tags they affect. Plus there are several other updates here that will make it easier to understand who can see your stuff (or your friends') in any context," Cox said.While privacy advocates reserved judgment until the new settings are actually released, they were optimistic the changes will benefit consumers."These changes do make me feel very confident in the direction that Facebook is going and the way they are thinking about privacy," said Erica Newland, policy analyst for the Center for Democracy & Technology in Washington, D.C.

BEIJING, Aug. 13 (Xinhua) -- Chinese rating agency Dagong Global Credit Rating Co. on Saturday defended its AAA rating given to the Ministry of Railways, which has been under public fire over a train collision last month.The ministry received the long-term credit rating after launching on Monday its first bond sales since the crash on July 23 that killed 40 people near the Wenzhou city of eastern Zhejiang province.It sold 20 billion yuan worth of three-month bills on offer in the interbank market, with a yield of 5.55 percent, a relatively high rate for short-term government paper.The rating was assigned because of the ministry's status as a government agency backed by the central government revenue, its sufficient capital flows and strong financing ability, Dagong said in an email to Xinhua.The agency made the elaboration in response to market doubts as the ministry is already heavily indebted and the accident has stirred up skepticism about the its credibility and the safety of fast-expanding railways.Adding to doubts is that the AAA rating of the ministry is even a notch above China's local currency debt rating of AA+, which was also rated by Dagong.Government data showed the ministry's debts exceeded 2 trillion yuan (313 billion U.S. dollars) as of the end of June, raising its debt ratio to 58.53 percent, slightly up from the end of the first quarter of this year.Dagong said in the statement that the debt-to-asset ratio is medium level, lower than the alert line for the ministry which is 75 percent.The ministry has large-scale assets of good quality and relatively large room for fund-raising, Dagong said.The ministry has "extremely strong" repayment ability as it is backed by the state's credit, Dagong said, referring it as one of the three authorities that are allowed to issue bonds, along with the Ministry of Finance and the People's Bank of China.In July, the ministry issued 20 billion yuan of one-year commercial papers with a coupon rate of 5.18 percent, but only 18.73 billion yuan of the total was bought.Analysts said it has become more difficult for the ministry to borrow money because of tightened market liquidity and concerns over the ministry's debt burden.China's top four banks said at the end of last month that they will continue to offer loans to the ministry based on market conditions and risk appraisal. Credit from the four largest state-owned banks including the Industrial and Commercial Bank of China and the Construction Bank of China has been the major source funding the construction of China's fast-growing railways in recent years.

BEIJING, June 3 (Xinhua) -- Google lacked evidence to support its accusations that Chinese hackers are behind the alleged cyber attacks on hundreds of its email accounts and the timing to make such accusations is evil-intentioned, Chinese experts said on Friday."Google's accusation is neither serious nor credible as it has not published any evidence that shows the hackers are from China," said Dai Yiqi, a cyber security expert with Tsinghua University.Eric Grosse, engineering director of Google's Security Team wrote on the company blog Wednesday that unidentified hacker attacks likely originated from the eastern Chinese city of Jinan, tried to collect user passwords of the Gmail accounts of hundreds of users, including senior U.S. government officials, Chinese "human rights activists" and journalists.A report released in 2009 by the United States-China Economic and Security Review Commission, an organization created by the U.S. Congress, claimed that Jinan is the home of a Chinese military reconnaissance office.An anonymous cyber security expert believes, despite Google not referring to the Chinese government in the latest attack claim, the company is targeting the Chinese government by listing the victims of the attacks as those whom only the Chinese government are interested in."Both their intentions and the timing of the accusation are dubious," Dai said.Google's accusation followed on the heel of the reported Pentagon's first formal cyber strategy. The Wall Street Journal reported Tuesday that the Pentagon concluded that computer sabotage coming from another country can count as an act of war and the United States may respond by using traditional military force.Li Shuisheng, a research fellow with a top military science academy of the People's Liberation Army, believes there are political motives behind Google's accusation.Google may well have attempted to instigate a new round of the cyber row between China and the United States, Li said.Wednesday's accusation by Google came more than a year after the company allegedly uncovered a cyber attack on its systems that it said it traced to China.In January, 2010, Google said it had been attacked by hackers supported by the Chinese government, and later announced to withdraw from Chinese mainland. The row ended up with Google redirecting Chinese mainland users to a site in Hong Kong.In such cyber attacks, it is easy to locate the IP address of hackers but hard to tell where the hackers actually are, said Dai."Hackers usually launch attacks by camouflaging their own IP addresses or controlling computers of others. Therefore, we can hardly tell the location of the hacker unless we have sufficient evidence," he said.China is one of the leading targets of cyber attacks. It has the world's largest number of computers infected with bot, a type of malware which allows a cyber attacker to gain control over the affected computer.About 13 percent of the world's computers infected with bot are in China."Without cooperation between governments, absolute security cannot be guaranteed in cyber community," said Li , adding only cooperation can ensure safe information exchange.

BEIJING, Sept. 27 (Xinhuanet) -- People having a dog is way healthier than those don't, both physically and mentally, media reports said Tuesday.People owning dogs are more likely to take exercises than those having none, according to a recent poll of Mars Petcare, a pet food company.Two thirds of the walks dog owners take each week are attributed to their dogs, according to the poll, in which over 1,000 adults were surveyed.The survey also showed that 44 percent of dog owners over 65 years old make exercises because of their dogs.Dogs are a great motivator for doing exercises, said Dr. Sandra McCune, an animal behaviorist and also co-author of the book, "The Health Benefits of Dog Walking for People and Pets".

WASHINGTON, July 15 (Xinhua) -- Researchers at Mount Sinai School of Medicine have found that grape seed polyphenols -- a natural antioxidant -- may help prevent the development or delay the progression of Alzheimer's disease.The research, led by Giulio Pasinetti, was published online Friday in the Journal of Alzheimer's Disease, which causes brain changes that gradually get worse.This is the first study to evaluate the ability of grape- derived polyphenols to prevent the generation of a specific form of amyloid (A) peptide, a substance in the brain long known to cause the neurotoxicity associated with Alzheimer's disease.In partnership with a team at the University of Minnesota, Pasinetti and collaborators administered grape seed polyphenolic extracts to mice genetically determined to develop memory deficits and A neurotoxins similar to those found in Alzheimer's disease. They found that the brain content of the A*56, a specific form of A previously implicated in the promotion of Alzheimer's disease memory loss, was substantially reduced after treatment.Previous studies suggest that increased consumption of grape- derived polyphenols, whose content, for example, is very high in red wine, may protect against cognitive decline in Alzheimer's. This new finding corroborates those theories."Since naturally occurring polyphenols are also generally commercially available as nutritional supplements and have negligible adverse events even after prolonged periods of treatment, this new finding holds significant promise as a preventive method or treatment, and is being tested in translational studies in Alzheimer's disease patients," said Pasinetti.In Alzheimer's disease, brain cells degenerate and die, causing a steady decline in memory and mental function.
