BEIJING, Aug. 30 (Xinhuanet) -- The United Nations is warning authorities to be on high alert of bird flu as the virus appears to be returning.The UN Food and Agriculture Organization said in a statement Monday a mutant strain is spreading across parts of Asia, and there could be a spill-over to humans.However, it said at this stage, there's no need for any alarm.A mutant strain of H5N1, which can apparently sidestep defenses of existing vaccines, is spreading in China and Vietnam, it said.It said the variant of the virus appears able to side step Vaccines.The UN is concerned the new form of the virus could spread to Cambodia, Thailand and Malaysia, as well as the Korean Peninsula and Japan."Wild birds may introduce the virus, but people's actions in poultry production and marketing spread it," said FAO's chief veterinary office Juan Lubroth in urging greater preparedness and surveillance, according to media reports.Outbreaks of the virus peaked in 2006 before it was eradicated from most countries.

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.

SUVA, July 25 (Xinhua) -- There are 400,000 people suffering from anaemia in Fiji with a total of population at about 800,000 people, according to the Health Ministry on Monday.Health Minister Doctor Neil Sharma told media that currently 60 per cent of children less than five years old are iron deficient, 40 per cent of women lack iron while 20 per cent of men suffer from iron deficiency in the island nation.Sharma, therefore, called on every family to grow local, eat local and move back to our traditional food habits, telling anaemic, "Do not forget to take your iron tablets."National Advisor Non-Communicable Diseases, Dr Isimeli Tukana also told media on Monday that strategies would include implementing the Food and Health Guidelines for the country in all clinics.All females are supposed to take their iron medication while all pre and primary school children will be given iron supplementation, he added.According to Fiji's Agriculture and Nutrition Department, the island nation, which is in transition towards increasing industrialization, is facing nutritional problems associated with both under-nutrition and over-nutrition.Lack of access to food due to economical shortages is one of the major causes of malnutrition in the country as one quarter of the population is living below the poverty line and most are living in illegal squatter settlements in search of employment and educational opportunities in urban areas.The problem of over-nutrition, on the other hand, may be associated with the change in the consumption patterns towards a diet high in energy but low in fibre, vitamins and minerals and a sedentary lifestyle.

WASHINGTON, July 7 (Xinhua) -- Space shuttle Atlantis will soar into the sky Friday on NASA's 135th and final flight. Its scheduled return to Earth later this month will mark the end of NASA's 30-year space program.Since its onset with the launch of space shuttle Columbia, the program has been seen as a cheap, safe and reliable way for space exploration.Despite its great contributions to U.S. manned space flight, it has also left some grave and tragic lessons, making its termination inevitable.HIKING COSTSLaunched in 1972 by then President Richard Nixon, the shuttle program aimed to provide a new system of affordable space travel and proved to be NASA's most enduring project in its 50 years of existence.In 1981, shuttle Columbia made its first shuttle flight for two days. It was the ultimate hybrid and the first reusable spacecraft.Launched like a rocket and gliding back to Earth like an airplane, space shuttles not only can act as a space taxi to carry astronauts, but have the muscle of a long-distance trucker to haul heavy machinery.The spaceship boasts more than 3,500 subsystems and 2.5 million parts and is nine times faster than a speeding bullet as it climbs heavenward. That versatility, however, has translated into higher costs.NASA originally estimated the program would cost about 90 billion U.S. dollars. However, its actual cost stands at about 200 billion dollars, compared with the 151 billion dollars spent on Apollo which took Americans to the moon in 1969.In an article in Technology Review, John Logsdon, former head of the Space Policy Institute at George Washington University, drew a direct connection between the ravenous shuttle budget and the lack of other large advances in manned space flight."By operating the system for 30 years, with its high costs and high risk, rather than replacing it with a less expensive, less risky second-generation system, NASA compounded the original mistake of developing the most ambitious version of the vehicle," he wrote."The shuttle's cost has been an obstacle to NASA starting other major projects," he added.HIGH RISKIn terms of safety, the shuttles have never been as reliable as their designers had envisioned.On average, one out of every 67 flights ended up with fatal accidents. Based on the rate of deaths per million miles traveled, the space shuttle is 138 times riskier than a passenger jet.Seven astronauts onboard died when Challenger exploded about a minute after launch in 1986. Nearly two decades after the tragic blast, a new catastrophe descended when the shuttle Columbia disintegrated moments before landing in 2003, killing another seven spacemen.Again, the shuttle program was shelved for more than two years as NASA stepped up efforts to make it safer. But experts say the fundamental problem related to shuttles' safety cannot be solved due to their "birth defects.""It is in the nation's interest to replace the Shuttle as soon as possible," concluded the panel that investigated the 2003 Columbia accident.

SAN FRANCISCO, Sept. 12 (Xinhua) -- More U.S. Internet users will access Internet through mobile devices than through PCs or other wireline devices by 2015, market research company International Data Corporation (IDC) said in its latest study released on Monday.According to IDC, the number of mobile Internet users will grow by a compound annual growth rage of 16.6 percent between 2010 and 2015, as mobile devices sales, such as smartphones and media tablets, explode."The impact of smartphone and especially, media tablet adoption will be so great that the number of users accessing the Internet through PCs will first stagnate and then slowly decline," said IDC in a forecast.Western Europe and Japan will not be far behind the U.S. in following this trend, the study noted.IDC also predicts that some 40 percent of the world's population will have access to Internet in 2015, when the total number of Internet users will grow to 2.7 billion from 2 billion in 2010."Forget what we have taken for granted on how consumers use the Internet," Karsten Weide, IDC's research vice president of media and entertainment, said in a statement."Soon, more users will access the Web using mobile devices than using PCs, and it's going to make the Internet a very different place," he added.
