BERLIN, June 9 (Xinhua) -- A 57-year-old man died of E. coli infection in Germany's Frankfurt Thursday, pushing the death toll from the bacteria to 30.The man had traveled with his wife to the city of Hamburg, an epicenter of the outbreak, Frankfurt authority said.Another two deaths were reported in the state of Lower Saxony, including a 68-year-old man and a 20-year-old woman, while more than 2,800 people in 14 countries have been infected since the deadly E. coli outbroke.German researchers detected again the deadly strain o104 of E. coli on the scraps of cucumbers in a dustbin in the eastern city of Magdeburg in the state Saxony-Anhalt on Wednesday.German health minister Daniel Bahr expressed his cautious hope for the disease on Wednesday as the number of new infection is clearly going down.But he also admitted there will be new cases and more deaths have to be expected, as Germany's national disease control centre, the Robert Koch Institute reported more than 300 infection in Germany on the same day.The Robert Koch Institute also noticed the declining trend in new cases but it was not clear whether this was caused by people staying away from vegetables or the outbreak was truly waning.

Beijing, Sept. 6 (Xinhua) -- A sperm donation scandal disclosed recently has aroused growing concern in the United States.According to the New York Times' report, Ryan Kramer, the son of a donor, found that he has more than 150 half-siblings - they are all the children of the same donor."It's wild when we see them all together - they all look alike," said Cynthia Daily, mother of Kramer.As more women choose to have children on their own, the demand for sperm donors has surged.Some sperm banks are earning huge profits by allowing too many mothers to receive sperms from the same popular donors, according to the report.And this trend will lead to risks: rare genetic diseases could be spread more widely, and the children of the same donor could meet and, unbeknownst to them, commit incest, medical experts warned.Parents and donors are calling for a tighter regulation so that donor children can know more about their donors, and the number of kids from each donor can be limited.

WASHINGTON, July 15 (Xinhua) -- Coastal communities along the U. S. East Coast may be at risk to higher sea levels accompanied by more destructive storm surges in future El Nino years, according to a new study published Friday by the U.S. National Oceanic and Atmospheric Administration (NOAA).The study was prompted by an unusual number of destructive storm surges along the East Coast during the 2009-2010 El Nino winter.The study, led by Bill Sweet, from NOAA's Center for Operational Oceanographic Products and Services, examined water levels and storm surge events during the "cool season" of October to April for the past five decades at four sites representative of much of the East Coast: Boston, Atlantic City, Norfolk and Charleston.From 1961 to 2010, it was found that in strong El Nino years, these coastal areas experienced nearly three times the average number of storm surge events (defined as those of one foot or greater). The research also found that waters in those areas saw a third-of-a-foot elevation in mean sea level above predicted conditions."High-water events are already a concern for coastal communities. Studies like this may better prepare local officials who plan for or respond to conditions that may impact their communities," said Sweet. "For instance, city planners may consider reinforcing the primary dunes to mitigate for erosion at their beaches and protecting vulnerable structures like city docks by October during a strong El Nino year."El Nino conditions are characterized by unusually warm ocean temperatures in the Equatorial Pacific that normally peak during the Northern Hemisphere "cool season." They occur every three to five years with stronger events generally occurring every 10-15 years. El Nino conditions have important consequences for global weather patterns, and within the U.S., often cause wetter-than- average conditions and cooler-than-normal temperatures across much of the South.

WASHINGTON, Sept. 27 (Xinhua) -- Debris from NASA's decommissioned Upper Atmosphere Research Satellite (UARS) that crashed to Earth on Saturday fell harmlessly in a remote area of the South Pacific Ocean, NASA said on Tuesday.According to the space agency, the Joint Space Operations Center at Vandenberg Air Force Base in California has determined the satellite entered the atmosphere over the Pacific Ocean at 14.1 degrees south latitude and 170.2 west longitude at midnight EDT Saturday. The debris field is located between 300 miles and 800 miles downrange, or generally northeast of the re-entry point."This location is over a broad, remote ocean area in the Southern Hemisphere, far from any major land mass," NASA announced, adding that it is "not aware of any possible debris sightings from this geographic area."NASA scientists estimated a 1-in-3,200 chance a satellite part could hit someone on earth. Therefore, any individual's odds of being struck are about one in 21 trillion.The UARS satellite, launched in 1991 from a space shuttle, was the first multi-instrumented satellite to observe numerous chemical constituents of the atmosphere with a goal of better understanding atmospheric photochemistry and transport.

BEIJING, Sept. 26 (Xinhuanet) -- One of the world's brightest minds aims to bring to the world a new, advanced three-dimensional image technology that will leave other such technology in the shadows."Our new technology will be better than that used in Avatar," says Professor Yau Shing-tung of Harvard University."The image will be more vivid than with technologies used in previous movies. The new technology is not only quicker but cheaper."Yau is one of the world's greatest mathematicians, having won the prestigious Fields Medal. He was once the dean of the department of mathematics at Harvard, and is now a professor there. He is also a visiting professor at Tsinghua University.Professor Yau and his team met professionals from Tsinghua University and Renmin University of China last week, and they discussed possible cooperation to apply the technology in making a demonstration movie using the new technology.Yau and a team started working on the new 3D technology, founded on geometrical principles, at Harvard 10 years ago.What marks it out is the extremely vivid pictures it produces.3D technology is used not only in making movies and in Internet games but in other areas , such as medicine. Movie audiences the world over were awestruck by the technology used in the movie Avatar."After I watched the movie, all I could say was 'Wow'," said Shen Yiren, an IT staff worker in Zhongguancun Science and Technology Park Zone. "3D technology has extended the boundaries of the human imagination."Yau says that six years ago the makers of Avatar had wanted him to cooperate with them but he turned them down."I was not sure that (Avatar) would be such a big success."Avatar's facial caption technology puts points on models' faces while the new technology uses geometric methods, saving time and money, Yau says.
