SAN FRANCISCO, Nov. 21 (Xinhua) -- E-commerce and online payment giant eBay announced on Monday that it has acquired New York-based technology startup Hunch, an online platform that delivers customized recommendations to users based on their individual tastes.Hunch's team and expertise in areas like machine learning, data mining and predictive modeling are expected to help eBay to integrate more advanced recommendations into its website, said the San Jose, California-based company."Unlike traditional online retail approaches, Hunch will enable eBay to move beyond standard item-to-item recommendations and use a broader variety of members' online tastes and interests to suggest new and interesting items for them to browse and buy on eBay," said the company in a press release.Terms of the deal were not disclosed. Technology news site TechCrunch founder Michael Arrington said in his personal blog prior to the acquisition announcement that eBay would acquire Hunch for 80 million U.S. dollars.Hunch, co-founded by popular photo-sharing service Flickr co- founder Caterina Fake with an 11-person team of MIT graduates, was open to the public in 2009. According to eBay, Hunch's employees will remain with the company in New York.

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?"

ULAN BATOR, Dec. 1 (Xinhua) -- Mongolia will continue to curb the spread of HIV and strive to maintain a low prevalence of the AIDS epidemic, a government official said Thursday.Gansukh Battulga, an official with the National Committee on AIDS, told Xinhua that Mongolia is currently an HIV low-prevalence country with a total of 99 people, 15 of whom have died, infected with the virus that causes AIDS."Among the 99 HIV infected cases, 81 percent are men, and the remaining 19 percent are women," Battulga said. "Among the male infected cases, 83 percent belong to MSM (men who have sex with men) group while sex workers account for 54 percent of the female infected cases."The official said the government has launched a variety of programs and tasked the National Committee on AIDS to coordinate all organizations in fighting the epidemic.According to a National Strategy Plan for 2010-2015, Mongolia will strive to maintain its current low HIV-prevalence rate of below 5 percent in the most-at-risk population.

BEIJING, Dec. 30 (Xinhua) -- China will push to properly resolve the case of a Chinese skipper indicted by Japan, the Foreign Ministry said Friday.Spokesman Hong Lei said this is a common fishing case, and the Chinese embassy in Japan has dispatched officials to visit the skipper.China requests that Japan ensure the rights of the Chinese skipper, Hong said, and China is communicating closely with Japan in order to properly resolve the case.The Chinese government has been requiring fishermen to fish legally, Hong said, adding that the competent authorities have done a lot in this area, and he promised to promote the management and education of Chinese fishermen.Japanese prosecutors have indicted the captain of a Chinese fishing boat for illegally operating in Japanese waters, a local official said Friday.The Nagasaki District Public Prosecutors Office has finalized its case against Zhong Jinyin, 39, following his December 20 arrest near islands off southwest Japan, according to the official.The prosecutors have not indicated whether the skipper has admitted to the charge.

BEIJING, Nov. 30 (Xinhuanet) -- Heading football frequently may cause brain damage leading to subtle but serious declines in thinking and coordination skills, a new study suggested as quoted by media reports Wednesday.Researchers used an advanced MRI (Magnetic Resonance Imaging) technique to analyze changes in brain white matter of 32 adult amateur soccer players who head balls 436 times a year on average.The study found players who head football quite frequently -- with 1,000 or more a year -- showed abnormalities similar to traumatic brain injuries suffered in car accidents."This is the first study to look at the effects of heading on the brain using sophisticated diffusion tensor imaging," said Dr. Michael Lipton, a leading researcher and associate director of the Gruss Magnetic Resonance Research Center at the Albert Einstein College of Medicine in New York City."We found the real implication for players isn't from hitting headers once in a while, but repetitively, which can lead to degeneration of brain cells," he added.The researchers compared neurological images of study participants, whose average age was 31, and found those with the highest volume of headers had abnormalities in five areas of the brain, responsible for attention, memory, physical mobility and high-level visual functions.The findings come in the wake of mixed reports on the so-called "cognitive" consequences of frequently heading soccer balls at practice.Dr. Chris Koutures, a pediatrician and sports medicine specialist in Anaheim Hills, California, said the retrospective imaging study was fascinating, but needs more data to effectively determine safe header limits, especially for younger players.Dr. Lipton agreed neuropsychological damage from headers would be hard for a coach or physician to notice since cognitive problems develop gradually, and even players might not be aware of mild memory loss."We can't tell an individual today not to be heading a ball, but caution is a good thing," Lipton said. "We need more research for definitive answers and we have the advanced imaging tools to do it."
