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.

TAIPEI, Sept. 11 (Xinhua) - As the full moon emerged in the remote sky, families and friends, bringing their barbecue grills, meat, seafood and vegetables, gathered under the Dazhi Bridge nearby Jilong River, one of major barbecue sites for the Mid-Autumn Festival in Taipei.Many families came to the barbecue site as early as at 3 p.m. Sunday for preparation. A Taipei citizen surnamed Wu in his sixties brought all his 30 family members to the barbecue."Every year, our family come out for barbecue only at the occasion of Mid-Autumn Festival, because the festival is for family reunion," he said.He also brought some fireworks to celebrate the traditional Chinese festival.Together with Wu's family, hundreds of people gathered under the bridge for barbecue, an unique scene in Taiwan for the Mid-Autumn festival.Mooncakes are a traditional delicacy for the Mid-Autumn Festival, which falls on the fifteenth day of the eighth month on the lunar calendar, or Sept. 12 this year. The round mooncakes resemble the full moon, a symbol of family reunion in traditional Chinese culture as well as the major theme of the Mid-Autumn Festival.According to some local residents, in the 1980s several barbecue sauce companies competing for the market frequently organized fairs to promote barbecue-related products just before the Mid-Autumn festivals.Through the intensive promotion campaigns, barbecue eventually became a Mid-Autumn festival custom as important as eating mooncake in Taiwan.But mooncake and pineapple cake are still popular gifts for the traditional festival in Taiwan. Weeks ahead of the festival, the advertisements for different brands of mooncake and pineapple cake were carried on local newspapers.Between Ren'ai Road and Xinyi Road in downtown Taipei, there is a weekend flower market becoming one of the options for Taipei citizens to while off the Mid-Autumn Festival holiday.The flower market with 29-year history is in fact a parking lot during weekdays. But during the weekend, the 1.5-hectare area becomes one of the biggest flower markets in Taipei, with about 300 booths selling flowers and plants.A flower seller, surnamed Yang, said the number of buyers increased significantly on Saturday and Sunday, the first two days of the three-day Mid-Autumn Festival holiday and the sales rose by nearly 30 percent.The flower market also held an agricultural product fair on Sept. 10-12, on which tea, fruits and other agricultural products are sold.

VIENNA, Sept. 22 (Xinhua) -- Climate change and rising temperature in the long term can lead to water shortages in the Alps region, international experts warned Thursday at the Water-Scarce Final Conference in the Austrian eastern city Graz.The Alpine region originally is rich in water resources due to a large number of glaciers, spring and abundant rainfall either in summer or winter. But global warming may change this situation which has been shown in the past years that the water reserve has reduced gradually due to climate change, warned the experts.Observation data have shown a significant decrease of 25 percent in groundwater recharge in the past 100 years which has also resulted in the reduction of mountain spring.Director of the Provincial Department of Water Resources of Styria Johann Wiedner point out, in 2003, droughts occurred in the eastern part of the Alps, including the state of Styria and water shortages were also found in other regions of the Alps. He said the phenomenon was giving a warning that people "have to do something."To this end, the European Union begun a project called "Alp Water Scarce" three years ago to observe water reserves, air temperature, water temperature and water table in this region and study the relationships among them.Wiedner also admitted that there is no shortage of water at least in the short term and water supply for the local residents is totally insured.

CANBERRA, June 10 (Xinhua) -- Going to work when you are feeling sick can make you sicker in the long run, an expert told Australia's media on Friday.New Zealand sociologist Professor Kevin Dew from the Victoria University in Wellington, has assessed more than 40 papers about " presenteeism".He defined presenteeism as: "People that are turning up at work when they feel that they should be at home sick.""People feel compelled to go to work because someone else would have to take up the workload (and they have a) feeling of responsibility for not being able to care properly for patients (if they don't show up)," he told the Australia Associated Press on Friday.He said that evidence suggested people who go to work when they are sick can have long term negative effects on health and productivity.Evidence shows that presenteeism increases illness, including musculoskeletal pain, fatigue, depression, and serious coronary events. It also leads to exhaustion which, in turn, leads to more presenteeism.Prof. Dew said certain medical conditions like depression and migraine are also linked with presenteeism because they are not seen as legitimate reasons for absence.He has written an editorial in the latest issue of the British Medical Journal about his findings.

BEIJING, July 20 (Xinhuanet) -- Some U.S. soldiers returning from the Middle East have acquired constrictive bronchiolitis, a kind of lung damage virtually unknown in young adults, according to U.S. News & World Report."Respiratory disorders are emerging as a major consequence of service in southwest Asia," said study author Dr. Matthew S. King, an assistant professor of pulmonary and critical care at Meharry Medical College in Nashville, Tenn."In addition to our study, there have been studies showing increases in asthma, obstructive lung disease, allergic rhinitis and a general increase in reports of respiratory symptoms," he added. "Most of the patients say they can’t seem to catch their breath when exerting themselves."On the other hand, Anthony Szema, a physician and engineer at Stony Brook University in New York, has examined a soldier and found tiny complexes of titanium and iron in the man’s lungs, where metals can cause severe damage.Mined separately, the two metals could have gotten together only through a manufacturing process, Szema reported. While the metals’ origin is unclear, he presents a new case study, suspecting garbage-burning pits or exploding devices sent them airborne.While the cases in the study represent only a few dozen people of the hundreds of thousands serving in the Middle East, there is no estimate of how many more might have bronchiolitis.it is recommended that soldiers exercise caution in the field until more is known. Soldiers are now told to wear a mask when burning garbage.
