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.

SYDNEY, Aug. 25 (Xinhua) -- Scientists in Australia have discovered a way of stopping mosquitoes carrying dengue virus, raising hopes for preventing the 50 million human cases of the disease every year, local media reported on Thursday.Groundbreaking experiments in Queensland have found a common insect bacteria, wMel Wolbachia, which can dramatically reduce the presence of dengue fever in mosquitoes.The research, led by Professor Scott O'Neill, Dean at Melbourne's Monash University, was published on Thursday in the prestigious journal, Nature.Australian researchers working on the Eliminate Dengue program aim to protect the mosquitoes themselves from dengue and so stop them transmitting the virus to humans."What the experiments have shown is that this strain of Wolbachia when it is put into mosquitoes really reduces the ability of the (dengue) virus to grow in the mosquito and if it can't grow, then it can't get transmitted in people," O'Neill told reporters.O'Neill said while it was too early to say if the experiments heralded the end of dengue fever, it was a major step towards that goal.In the past decade, there have been 2400 cases of dengue fever reported during 36 outbreaks in Australia.Dengue fever has become endemic in tropical regions, where it is spread by a specific type of mosquito that becomes infected after biting humans with the disease.Despite millions of people being infected with dengue each year, there is currently no way of stopping its rapid spread either by vaccines or controlling mosquito populations.Further trials will be conducted in Cairns in north Queensland over the coming wet season and approval is currently being sought for trials in Thailand, Vietnam, Brazil and Indonesia that will directly determine the effectiveness of the method in reducing dengue disease in human populations, according to Monash University.

WARSAW, June 2 (Xinhua) -- A possible second E. coli infection patient has been hospitalized in Szczecin, northwestern Poland, Health Minister Ewa Kopacz said Thursday.The man, who recently returned to Poland from Germany, has been diagnosed with exudative diarrhea and is currently being tested for E. coli bacteria.Poland's first E. coli case, a 29-year-old woman permanently residing in Germany and diagnosed with the bacteria over a week ago, is currently in the same hospital.Kopacz said sanitary teams were running E. coli checks countrywide, especially on marketplaces and in warehouses.The E. coli epidemic originated in Germany, where it has taken 17 lives. One death has so far occurred in Sweden, bringing the total death toll to 18.

BEIJING, Sept. 14 (Xinhuanet) -- The U.S. Food and Drug Administration (FDA) on Monday announced a recall on a drug infusion pump of Medtronic, the Associated Press reported.The recalled drug pump was called "SynchroMed II", including models of 8637-20 and 8637-40, distributed between 2004 and July 2011.Drug infusion pump was used to deliver the drugs for patients to treat chronic pain, spasms as well as other conditions.The pumps' malfunction could put patients in the risk of either recurrent or withdrawal symptoms, which could be life-threatening, FDA warned.There were 55 reported cases and one death related to the drug withdrawal, among a total 139,653 SynchroMed II pump implants worldwide, FDA notified.The problem was due to a film within the pump's battery that could stop the therapy, FDA said.Medtronic, the U.S. medical technology company based in Minneapolis, is not recommending patients to remove the pumps, but instead, encourage patients to contact their doctor if they hear the device alarm.

SAN FRANCISCO, Sept. 13 (Xinhua) -- Intel and Google on Tuesday announced a partnership to enable the world's largest chip maker's architecture on the search giant's products, saying that an Intel chip-based Android smartphone will hit the market in the first half of 2012.In a joint press release, the two companies said the future versions of Android mobile operating system will support Intel's low power Atom processors, in addition to other architectures.At the Intel Developer Forum in San Francisco on Tuesday, Intel Chief Executive Officer Paul Otellini said the Intel smartphone chip is code-named Medfield and based on the company's own PC- based computer architecture.Otellini said multiple vendors around the world will launch the Medfield-based Android smartphones in the first half of 2012.Andy Rubin, senior vice president of mobile at Google, came on stage at the close of Otellini's keynote to hail the joint initiatives between the two companies.Intel has been struggling to get a bite of the booming market of smartphones and tablets. Most of the current mobile devices use chips based on architecture from ARM Holdings, which are considered more power efficient than Intel's products. Nokia had planned to ship smartphones with Intel chips this year, but it shifted to ARM-based phones with Windows Phone 7 system.Otellini said Intel will eventually have an advantage in supplying smartphone chips as the business is not established in terms of the final winner and performance of the products keeps growing.
