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, Aug. 24 (Xinhuanet)-- A new study shows that a diet rich in cholesterol-friendly foods, such as soy products and tree nuts, can decrease LDL (bad) cholesterol significantly, according to media reports on Tuesday.The study, published in the Journal of the American Medical Association, found that people who ate a healthy diet filled with cholesterol-lowering foods experienced a 13 percent decrease in their LDL cholesterol levels.For patients with high levels of so-called bad cholesterol, doctors usually have two prescriptions: cholesterol-lowering statin drugs and a diet that cuts out foods high in saturated fat, such as ice cream, red meat and butter.But the new study found that when it comes to lowering artery-clogging cholesterol, what you eat may be more important than what you don't eat.David Jenkins of St. Michael's Hospital and the University created the "portfolio diet," which includes regular consumption of tree nuts and high amounts of fiber from oats, barley and vegetables. The diet, which replaces butter with plant sterol-enriched margarine and substitute soy-based products for meat, allows maximum benefit in lowering cholesterol and preventing heart disease. "The study highlighted the power of food to lower risk for cardiovascular disease: What you do eat and what you don't eat are both important," said Dr. Jane Klauer, a New York internist specializing in metabolism and nutrition.A high overall cholesterol level makes a person nearly twice as likely to suffer a heart attack or stroke as someone whose total cholesterol falls into a healthy range.

TOKYO, June 19 (Xinhua) -- The Japanese gaming company Sega Corp. said in a statement on Sunday some personal information from more than 1.2 million registered users had been stolen after the website of its subsidiary based in Britain was hacked.The Sega Pass website operated by Sega Europe limited was designed to provide product news. The services were shutdown following the breach detected on Friday. They are still not resumed on the official website of the company late Sunday night and the company said it is investigating the hacking.The company said most of the users of the hacked website are in Europe and North America. A similar cyberattack had troubled the Sony group earlier in April. The hacking affected about 100 million people.

BEIJING, Aug. 12 (Xinhuanet) -- The risk of developing coronary heart disease is 25 percent higher for women smokers compared with men, according to a study published in the British medical journal "The Lancet".The authors say this could be due to the physiological differences between the sexes with cigarette smoke toxins having a more potent effect on women.The study by Dr Rachel R Huxley from the University of Minnesota and Dr Mark Woodward from Johns Hopkins University involved a meta-analysis of around four million individuals and 67,000 coronary heart disease events from 86 studies.The researchers found that the pooled adjusted female-to-male relative risk ratio (RRR) of smoking compared with not smoking for coronary heart disease (CHD) was 1.25 (25 percent) higher for women.This RRR increased by 2 percent for every additional year of follow-up, meaning that the longer a woman smokes, the higher her risk of developing CHD becomes compared with a man who has smoked the same length of time.The authors say, "The finding lends support to the idea of a pathophysiological basis for the sex difference. For example, women might extract a greater quantity of carcinogens and other toxic agents from the same number of cigarettes than men. This occurrence could explain why women who smoke have double the risk of lung cancer compared with their male counterparts."Worldwide, there are 1.1 billion smokers, of whom a fifth are women.According to the Tobacco Atlas, India, with around a crore female smokers, ranks third in the top 20 female smoking populations across the globe, only the U.S. with 2.3 crore female smokers and China with 1.3 crore female smokers, are worse off.

JIUQUAN, Gansu, Sept. 26 (Xinhua) -- Engineers are conducting the final preparations before launching China's first space laboratory module at the end of this week at a launch center in northwest China.The unmanned Tiangong-1 module was originally scheduled to be launched into low Earth orbit between Sept. 27 and 30. However, a weather forecast showing the arrival of a cold air mass at the Jiuquan Satellite Launch Center forced the launch to be rescheduled for Sept. 29 or 30, depending on weather and other factors."This is a significant test. We've never done such a thing before," said Lu Jinrong, the launch center's chief engineer.A full ground simulation was conducted on Sunday afternoon to ensure that the module and its Long March 2F carrier rocket are prepared for the actual launch.Cui Jijun, commander-in-chief of the launch site system and director of Jiuquan Satellite Launch Center, told Xinhua that they developed a new target spacecraft for the mission and made more than 170 technical improvements to the Long March 2F, China's manned orbital carrier rocket.Engineers have also made more than 100 updates at the launch site in order to make it compatible with the Tiangong-1, Cui added.The module will conduct docking experiments after entering orbit, which is the first step in China's space station program.Cui said the launch site has an updated computer center and command monitoring system and increased ability to adapt to changes in mission conditions, as well as the resources to handle both the launch and command duties. An integrated simulation training system for space launching has also been developed for the docking mission.The mission comes just one month after the Long March 2C rocket malfunctioned and failed to send an experimental satellite into orbit. The Tiangong-1 mission was subsequently rescheduled in order to allow engineers to sort out any problems that might occur during the launch.Cui said that engineers conducted a two-month comprehensive technical check on equipment at the launch site from March to May. The safety and reliability of all the instruments have been significantly improved."[The launch site] has the full conditions to conduct the Tiangong-1 mission," said Cui.The Tiangong-1 will remain in orbit for two years. During its mission, it will dock with China's Shenzhou-8, -9 and -10 spacecrafts.Unmanned docking procedures will be an essential step toward China achieving its goal of establishing a manned space station around 2020.
