BEIJING, Oct. 10 (Xinhuanet) -- China's small businesses turned to be the first to ring the alarm as the country is walking a fine line between fighting inflation and maintaining growth.Some entrepreneurs have disappeared and others have jumped off buildings almost every week since April in Wenzhou City, an entrepreneurial capital in eastern China's Zhejiang province, Xinhua reported.The sudden disappearance of the business owners has revealed a surprisingly gloomy picture for the small and medium-sized enterprises (SMEs) in China.RUNAWAY BOSSESAccording to a Xinhua investigation, at least 80 cash-strapped businesspeople in Wenzhou have skipped town or declared bankruptcy to invalidate more than 10 billion yuan (1.6 billion U.S. dollars) in debt.Just last month, two local entrepreneurs in Wenzhou killed themselves by jumping off the buildings and another broke his leg in a similar suicide attempt.The tragedies in Wenzhou are extreme cases of private SMEs struggling to survive a liquidity crunch amid the country's macro control policies set to curb inflation and cool down the over-heated property market.In Wenzhou, one-fifth of the 360,000 small and mid-sized businesses have stopped operating due to cash shortages, according to the city's council for small and medium-sized enterprises.Of the 855 companies surveyed by the Wenzhou Economic and Information Commission, more than 76 percent said they are almost out of money and are struggling to continue production.But many cash-strapped firms are unable to borrow money from banks, and some have turned to China's underground lending market to pool money from individuals and firms.The steep rates of the informal loans pushed some businesses to the brink of collapse.

BEIJING, Oct. 11 (Xinhuanet) -- Scientists have discovered that blind optimism is related to brain's frontal lobes which are associated with processing errors, according to a British study published Monday in the journal Nature Neuroscience.Scientists at the University College of London scanned brains of volunteers who were asked to estimate their personal likelihood of involving in negative events, like a divorce or cancer,  before and after given the average probability of these events occurring.They found that the volunteers who estimated lower probability (or the more optimistic ones) than the given one raised their estimates a little bit later while those estimated higher probability altered their estimates much more.Through the brain scanner, scientists saw there was less activity in the volunteers' frontal regions when the information given was worse than expected while more activity when the information was better than expected. It suggested that the more optimistic people neglected the negative predictions."The more optimistic we are, the less likely we are to be influenced by negative information about the future," said Dr. Tali Sharot, lead author of the study. He added being optimistic clearly had some benefits, "but it can also mean that we are less likely to take precautionary action, such as practising safe sex or saving for retirement. So why don't we learn from cautionary information?"

SAN FRANCISCO, Dec. 15 (Xinhua) -- Microsoft on Thursday announced that it will automatically upgrade the Internet Explorer (IE) to the latest version to give Windows customers more protection against malicious software.According to the company's blog post, starting from Australia and Brazil next January, users of Windows XP, Vista and Windows 7 will get the IE updates if they have turned on automatic updating via Windows Update.Microsoft said the industry has been moving toward automatic updates as a norm since the biggest online threat these days is social engineering malware typically targeting outdated software like Web browsers.Automatic upgrades, also called silent updates for displaying no messages or windows during the progress, has been deployed by Google's Chrome and Mozilla's Firefox. It can ensure users have the newest versions of the browser, and therefore is seen as a big improvement to Internet security.According to the Microsoft Security Intelligence Report released in October, 99 percent of all attacks during the first half of 2011 came from unpatched but known vulnerabilities, and 90 percent of infections were attributed to vulnerability exploitation that had a security update available from the software vendor for more than a year.In the latest research data from Web analytics company StatCounter, Microsoft's IE has a strong lead with 40.63 percent of global browser market share, followed by 25.7 percent of Chrome and 25.23 percent of Firefox.

WASHINGTON, Nov. 22 (Xinhua) -- Long-term coffee consumption may be associated with a reduced risk for endometrial cancer, according to a study published online Tuesday in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.Edward Giovannucci, professor of nutrition and epidemiology at the Harvard School of Public Health, said that coffee is emerging as a protective agent in cancers that are linked to obesity, estrogen and insulin."Coffee has already been shown to be protective against diabetes due to its effect on insulin," said Giovannucci, a senior researcher on the study. "So we hypothesized that we'd see a reduction in some cancers as well."The researchers observed cumulative coffee intake in relation to endometrial cancer in 67,470 women who enrolled in the Nurses' Health Study. During the course of 26 years of follow-up, researchers documented 672 cases of endometrial cancer.Drinking more than four cups of coffee per day was linked with a 25 percent reduced risk for endometrial cancer. Drinking between two and three cups per day was linked with a seven percent reduced risk.A similar link was seen in decaffeinated coffee, where drinking more than two cups per day was linked with a 22 percent reduced risk for endometrial cancer.Giovannucci said that he hopes this study will lead to further inquiries about the effect of coffee on cancer because in this and similar studies, coffee intake is self-selected and not randomized.
