WASHINGTON, Sept. 27 (Xinhua) -- At least 13 people had been killed amid 72 sickened in 18 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 Tuesday in a statement posted on its website.Of the 13 deaths, four were in New Mexico, two were in Colorado, two were in Texas, and there was one each in Kansas, Maryland, Missouri, Nebraska and Oklahoma.Victims range in age from 35 to 96 years, with an average age of 78. All of the illnesses started on or after July 31.The figures were the latest confirmed as of Monday morning, according to the CDC. But they may well rise in the still-widening outbreak as state and local officials are investigating three additional deaths that may be connected.In 1998, 21 people died from listeria linked to tainted hot dogs, according to a CDC online database.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.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.

LOS ANGELES, June 9 (Xinhua) -- The edge of our solar system may not be smooth, but filled with a turbulent sea of magnetic bubbles approximately 100 million miles (160 million kilometers) wide, NASA's Jet Propulsion Laboratory (JPL) said on Thursday.The finding was based on observations from NASA's Voyager spacecraft, humanity's farthest deep space sentinels, said JPL in Pasadena, Los Angeles.While using a new computer model to analyze Voyager data, scientists found the sun's distant magnetic field is made up of bubbles which are created when magnetic field lines reorganize, said JPL.The new model suggests the field lines are broken up into self- contained structures disconnected from the solar magnetic field, according to JPL."The sun's magnetic field extends all the way to the edge of the solar system," said astronomer Merav Opher of Boston University. "Because the sun spins, its magnetic field becomes twisted and wrinkled, a bit like a ballerina's skirt. Far, far away from the sun, where the Voyagers are, the folds of the skirt bunch up."Like Earth, our sun has a magnetic field with a north pole and a south pole. The field lines are stretched outward by the solar wind, a stream of charged particles emanating from the star that interacts with material expelled from others in our corner of the Milky Way galaxy.Understanding the structure of the sun's magnetic field will allow scientists to explain how galactic cosmic rays enter our solar system and help define how the star interacts with the rest of the galaxy.The Voyager spacecraft, more than nine billion miles (14 billion kilometers) away from Earth, are traveling in a boundary region. In that area, the solar wind and magnetic field are affected by material expelled from other stars in our corner of the Milky Way galaxy.Launched in 1977, the Voyager twin spacecraft have been on a 33- year journey. They are en route to reach the edge of interstellar space. JPL built the spacecraft and continues to operate them.

BEIJING, Sept. 5 (Xinhua) -- China and the World Bank are jointly researching ways to help rebalance the world's second largest economy and move toward a path of sustainable growth under the current challenging global economic situation, said World Bank Group President Robert B. Zoellick on Monday.A report, jointly being prepared by the World Bank, China's Ministry of Finance, and the Development Research Center of the State Council, will be released later this year to support China in identifying the many challenges and policy choices it will face in the next two decades, as the country seeks to avoid the so-called "middle-income trap," a stage of economic development that has slowed progress in many countries, Zoellick said.Regarding this autumn as "a sensitive time facing the world's major economies," Zoellick said many countries, including the United States, the European Union and Japan, were facing the similar fundamental challenge of restructuring for sustainable economic growth."Perhaps the challenge is more difficult for China as the country has already made remarkable progress, and thus it's not easy to persuade people to make a change," he said.Commenting in Beijing on a weekend workshop with senior Chinese officials and outside experts, Zoellick said there was agreement that China will have to rebalance its economy, improve the environment, reduce inequality and advance the quality of life for its people while at the same time maintaining rapid growth."In the near term, inflation is China's priority, as Premier Wen Jiabao mentioned," Zoellick said, adding that the Chinese government was moving in the right direction, though it was too early to have the problem solved.In next 10 years, however, Zoellick said he could not imagine China continuing to rely on exports for growth, especially when developed economies have had difficulties recovering.By shifting away from an over-dependence on export-led growth to a greater reliance on domestic demand and investment, China could benefit not only itself but the world economy, he said.As China's 12th Five-Year Plan has pointed the way forward with what needs to be done, Zoellick said the ongoing research will try to help with the "how."He said the report will cover issues such as how China can complete its transition to a market economy; how to promote open innovation; how to advance green development; how to deliver equality of opportunity and social security to citizens; how to strengthen the fiscal system, and how China can become a responsible stakeholder in the international system.During his stay in China, Zoellick also visited the country's wasteland-turned-grain-producing-base in the northeast, including a farm, a rice mill, an agricultural research center and a modern agricultural machinery park, and learned about how this land transformation had affected local people's lives.As the world population is expected to hit 9 billion by 2050, Zoellick said the World Bank has been urging G-20 countries to prioritize food issues."China feeds 20 percent of the world's population with less than 10 percent of the world's agricultural land and less than six percent of its water, so China could make a significant contribution to global food security," Zoellick said.

YUEYANG, Hunan, June 2 (Xinhua) -- The population of finless porpoises, an endangered species of freshwater dolphin that lives in China's Yangtze River, may decrease by over 80 percent over the next 30 years, experts said on Thursday after conducting a field survey along the river.The rare species will edge closer to extinction if no action is taken, said Wang Ding, a dolphin expert from the Hydrobiology Institute of the Chinese Academy of Sciences.Wang's team conducted a survey on Poyang Lake, Dongting Lake and other locations along the Yangtze from Sunday to Wednesday this week.The dolphin population currently stands at 1,000, even lower than that of the giant panda, Wang said.The dolphin population is decreasing by a rate of 6.4 percent annually, Wang said."The next ten years will be a critical period for the conservation of this species," Wang said.A long-lasting drought in central China has lowered water levels in many of the region's lakes and rivers, doing great harm to the dolphins' habitat and leading to a decrease in population, Wang said.Mei Zhigang, a member of Wang's survey team, said that human activity has also contributed to the dropping population.Mei said that large numbers of shipping vessels on the Yangtze have impeded the dolphins' migration path, causing them to reproduce less frequently.

BERLIN, Aug. 28 (Xinhua) -- Mercedes-Benz, the world leading luxury car producer, celebrates the 125th anniversary of its invention of automobile with what it claimed the largest gathering ever, at the former Tempelhof airport in Berlin on the weekend.The Mercedes-Benz Club and Mercedes-Benz enthusiasts greet visitors with some 1,800 well-assorted Mercedes-Benz-branded vehicles, ranging from vintage and classic passenger cars to a variety of historic commercial vehicles, on a vast open areas of 250,000 square metres of the abandoned Tempelhof airport, which was closed in 2008.It took Mr. Lauritzen and his wife two days' drive of their cherised wecker of Mercedes-Benz Cabriolet B. 320.W 142.-3,4l to reach here for taking part in the pageant."It is a long journey, but we are happy to be here to see more class cars and more friends with same interests," Mrs Lauritzen said.Owners take the opportunity to present their lovingly cared-for vehicles, which include a number of truly rare items of automotive history, to the Berlin public.The couple of Mr. Kerner drove their red Mercedes-Benz 170Dba, a made-in-1952 model with a range of special and unique designs which are very rarely seen now, over journey of 155 km from Bitterfeld to join in the gala."I'm fond of driving my classic car of Benz," said Mrs Kerner, despite it can run maximally at a speed of 50 to 80 km per hour, "but I truly enjoy the diesel engine sounds and the historic feeling it evokes."The legendary Silver Arrows, dating from the 1930s and 1950s, are also presented from the Mercedes-Benz Classic collection for demonstration drives."The brilliant history of the Silver Arrows will be brought to life with a demonstration of their impressive engine sound and incredible driving dynamics," said Michael Bock, head of Mercedes-Benz Classic and Director of Mercedes-Benz Museum GmbH."It is not often that these racing cars are driven in public, so this will be a true highlight of the program of events in Tempelhof."During the grand show, visitors are also accessible to first-hand experiences of the latest technologies applicable in the future for in passenger cars, commercial vehicles and racing cars."Some 125 years ago, Carl Benz submitted his patent application for the Benz Patent Motor Car to the Patent Office in Berlin", the organizer appealed to the visitors, saying now Mercedes-Benz is returning to Berlin to celebrate together with Berliners.
