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, Jan. 1 (Xinhua) -- Chinese President Hu Jintao and his South Korean counterpart Lee Myung-bak exchanged new year greetings Sunday and announced the start of the "China-South Korea Friendly Exchange Year".In his message, Hu spoke positively of the relations between the two countries. Seizing the opportunity of the 20th anniversary of the establishment of the China-South Korea diplomatic relations, China is willing to work together with South Korea, by launching various exchange programs, to further promote mutual understanding and friendship between the two peoples, deepen communication and cooperation in all sectors, and push for constant progress of the bilateral relationship, Hu said.For his part, Lee said on the basis of the accomplishments achieved over the two decades of the bilateral diplomatic ties, South Korea looks forward to joining hands with China to build a better future for the bilateral relationship.

WASHINGTON, Sept. 30 (Xinhua) -- At least 15 people have been killed amid 84 sickened in 19 states in listeria outbreak traced to Colorado cantaloupes, making it the most deadly U.S. outbreak of food-borne infection since 1998, the Centers for Disease Control and Prevention (CDC) said Friday.Of the 15 victims, five were in New Mexico, three in Colorado, two in Texas, and one each in Kansas, Maryland, Missouri, Nebraska and Oklahoma. Health departments in Wyoming and Kansas have said they are investigating additional deaths that may be connected to the outbreak.The previous toll announced on Tuesday was 13 dead and 72 sick.The Food and Drug Administration on Sept. 14 warned consumers not to eat cantaloupes from Colorado's Rocky Ford region shipped by Jensen Farms. The cantaloupes with the brand name Rocky Ford were distributed from July 29 to Sept. 10 in at least 17 states."Even if some of the cantaloupe has been eaten without becoming ill, dispose of the rest of the cantaloupe immediately. Listeria bacteria can grow in the cantaloupe at room and refrigerator temperatures," the CDC said.Listeria is a common bacterium that typically causes mild illness in healthy people, but can cause severe illness in older people and those with compromised immune systems. It also can cause miscarriages and stillbirths in pregnant women and severe infections in new babies.Listeria infections lead to about 1,600 serious illnesses each year and about 260 people die, according to the CDC.The CDC estimates that about 48 million people in the U.S. each year get sick from tainted food, with about 128,000 hospitalized and 3,000 deaths.

WASHINGTON, Jan. 16 (Xinhua) -- A new study examining weather patterns around the worldwide pandemics of influenza, which caused widespread death and illness in 1918, 1957, 1968 and 2009, finds that each of them was preceded by La Nina conditions in the equatorial Pacific. The study findings are published online Monday in the Proceedings of the National Academy of Science.The study's authors -- Jeffrey Shaman of Columbia University's Mailman School of Public Health and Marc Lipsitch of the Harvard School of Public Health -- note that the La Nina pattern is known to alter the migratory patterns of birds, which are thought to be a primary reservoir of human influenza. The scientists theorize that altered migration patterns promote the development of dangerous new strains of influenza.To examine the relationship between weather patterns and influenza pandemics, the researchers studied records of ocean temperatures in the equatorial Pacific in the fall and winter before the four most recent flu pandemics emerged. They found that all four pandemics were preceded by below-normal sea surface temperatures -- consistent with the La Nina phase of the El Nino- Southern Oscillation.The authors cite other research showing that the La Nina pattern alters the migration, stopover time, fitness and interspecies mixing of migratory birds. These conditions could favor the kind of gene swapping or genetic reassortment that creates novel and therefore potentially more variations of the influenza virus."We know that pandemics arise from dramatic changes in the influenza genome. Our hypothesis is that La Nina sets the stage for these changes by reshuffling the mixing patterns of migratory birds, which are a major reservoir for influenza," says Shaman.Changes in migration not only alter the pattern of contact among bird species, they could also change the ways that birds come into contact with domestic animals like pigs. Gene-swapping between avian and pig influenza viruses was a factor in the 2009 swine flu pandemic.

BEIJING, Oct. 13 (Xinhuanet) -- Scientists have decoded the genome of Black Death which caused one of the worst plagues in human history.The finding was published Wednesday in the scientific journal Nature.A team of German, Canadian and American scientists collected the bacteria's DNA from ancient plague victims' teeth and bones, which were excavated from the burial ground in London.With a careful NDA comparison between the ancient bacteria and the modern strains, scientists found the direct variant of the medieval bacteria still exist today.Black Death's descendants kill around 2,000 people a year, mostly in the developing world, the scientist said."This will provide us with direct insights into the evolution of human pathogens and historical pandemics," said Johannes Krause Of Germany's University of Tubingen, who worked on the study.Black Death, the fatal plague of medieval Europe, wiped out some 30 million people -- about 50 percent of the population on the continent, within just five years, between 1347 and 1351.
