SHENZHEN, June 4 (Xinhua) -- Chinese scientists who have fully sequenced the genome of the new E. Coli spreading through Europe said Saturday they found genes in the bacteria that gave it resistance to eight classes of antibiotics.Researchers with the Beijing Genomics Institute, the world's largest DNA sequencing center, have found genes in the newly identified 0104 strain of E. Coli bacteria that made it resistant to major classes of antibiotics including sulfonamide, cephalothin, penicillin and streptomycin.This helped explain why doctors in Europe had difficulties in fighting the bug that has killed 18 people and sickened nearly 2,000, BGI's major research arm in Shenzhen said on its website Saturday.This would help doctors choose right medicines for the treatment, it said.The researchers are developing a diagnostic kit which will be used to detect the bacteria and prevent the epidemic from spreading further.The Chinese researchers obtained DNA samples of the bacteria from collaborating scientists in Germany and fully sequenced its genome in three days this week.They announced on Thursday the E. Coli spreading through Europe was "a new strain of bacteria that is highly infectious and toxic".The 0104 strain of E. Coli was not previously involved in any E. Coli outbreaks. However, it has 93 percent sequence similarity with the EAEC 55989 E. Coli strain which was isolated in the Central African Republic and known to cause seriously diarrhea, BGI said.The source of the outbreak is unknown, but scientists say it is highly likely to have originated in contaminated vegetables or salad in Germany.

PHNOM PENH, Aug. 17 (Xinhua) -- The critically endangered Irrawaddy dolphin population in the Mekong River numbers just 85, World Wildlife Fund (WWF) new research revealed on Wednesday.Calf survival was found to be very low, leading researchers to conclude that the small population is declining and at high risk of extinction, said the Fund's statement sent to Xinhua News Agency on Wednesday.According to Li Lifeng, Director of WWF's Freshwater Program, the research is based on photographic identification of dolphins through individually unique features of their dorsal fins. "Most of the dolphins can be identified, and we use that information to estimate the population size," he said.Although this population estimate is slightly higher than the previous estimate, the researchers were quick to note that the population had not increased over the last few years."With a larger dataset and recent analytical advances, previously unidentifiable dolphins which had few marks on their dorsal fins have been included," he added.However, surveys conducted from 2007 to 2010 show the population slowly declining."Evidence is strong that very few young animals survive to adulthood, as older dolphins die off and are not replaced," he explained."Pressures of gill net entanglement and high calf mortality we are really worried for the future of dolphins," Li said.However, Touch Seang Tana, chairman of Cambodia's Commission for Conversation and Development of the Mekong River Dolphins Eco- tourism Zone, rejected the WWF's finding, saying that last year, 4 dolphins were killed by fishing nets, but up to 7 newborn dolphin babies were found.He estimated that the total population of Mekong dolphins in the north-eastern provinces of Kratie and Stung Treng is between 155 and 177 now, up from just 100 in 2006.The Mekong River Irrawaddy dolphin has been listed as critically endangered on the World Conservation Union Red List of Threatened Species since 2004.

SYDNEY, June 29 (Xinhua) -- A type of dried seaweed sold in Asian food supermarkets in Australia has been recalled after it was found to have high levels of iodine dangerous to pregnant women, local media reported on Wednesday.Food Standards Australia New Zealand (FSANZ) has ordered the recall of Wang Dried Kelp Varech Speche, a Korean brand of the dried seaweed, according to Australian Associated Press (AAP).It has been available in Asian grocery stores and restaurants in the Brisbane and Gold Coast areas of Queensland."The product contains high levels of naturally occurring iodine," FSANZ said in a statement."Regular consumption of these products may cause health problems in some people including pregnant and breastfeeding women."FSANZ said consumers concerned about their health should seek medical advice and should return the products to the place of purchase for a full cash refund.

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. 2 (Xinhuanet) -- The first close-up pictures of the asteroid Vesta, a protoplanet that dates back to the early days of the solar system, were revealed Monday by NASA scientists.The images were taken by the U.S. space agency's Dawn robotic probe, which is two weeks into a planned year-long survey of the second largest object in the main asteroid belt, located between Mars and Jupiter.About twice the size of California, Vesta is second in size only to Ceres, Dawn's next target and, along with Pluto, one of just five known dwarf planets. NASA is spending 466 million dollars to explore Vesta and Ceres during the course of a 10-year mission.Images from Dawn show Vesta a surprisingly diverse terrain and several unexplained geologic features. Chaotic terrain near the south pole is dominated by a towering central peak and huge ripple-like grooves stretching around its equatorial belt. Bright spots, dark pits and craters are filled with unexplained streaks of black and white debris. Terrain north of the grooves is much more heavily cratered.Scientists believe Vesta grew from a clump of gas and dust left over after the sun's birth some 4.65 billion years ago, a supernova explosion, which added radioactive materials to the growing body.Dawn will spend about a year circling Vesta, tweaking its orbit and altitude using an innovative technology called ion propulsion system, chief engineer Marc Rayman with NASA's Jet Propulsion Laboratory in California said.The ion propulsion system will enable Dawn to leave Vesta's orbit after a year of study and head off to Ceres, which is the largest object in the asteroid belt.
