PHNOM PENH, Aug. 17 (Xinhua) -- The critically endangered Irrawaddy dolphin population in the Mekong River numbers just 85, World Wildlife Fund (WWF) new research revealed on Wednesday.Calf survival was found to be very low, leading researchers to conclude that the small population is declining and at high risk of extinction, said the Fund's statement sent to Xinhua News Agency on Wednesday.According to Li Lifeng, Director of WWF's Freshwater Program, the research is based on photographic identification of dolphins through individually unique features of their dorsal fins. "Most of the dolphins can be identified, and we use that information to estimate the population size," he said.Although this population estimate is slightly higher than the previous estimate, the researchers were quick to note that the population had not increased over the last few years."With a larger dataset and recent analytical advances, previously unidentifiable dolphins which had few marks on their dorsal fins have been included," he added.However, surveys conducted from 2007 to 2010 show the population slowly declining."Evidence is strong that very few young animals survive to adulthood, as older dolphins die off and are not replaced," he explained."Pressures of gill net entanglement and high calf mortality we are really worried for the future of dolphins," Li said.However, Touch Seang Tana, chairman of Cambodia's Commission for Conversation and Development of the Mekong River Dolphins Eco- tourism Zone, rejected the WWF's finding, saying that last year, 4 dolphins were killed by fishing nets, but up to 7 newborn dolphin babies were found.He estimated that the total population of Mekong dolphins in the north-eastern provinces of Kratie and Stung Treng is between 155 and 177 now, up from just 100 in 2006.The Mekong River Irrawaddy dolphin has been listed as critically endangered on the World Conservation Union Red List of Threatened Species since 2004.

BEIJING, Aug. 5 (Xinhuanet) -- A study conducted by Israeli researchers at the Albert Einstein College of Medicine in New York shows that genes, rather than good eating and lifestyle habits, determine longevity, according to media reports Friday. "This study suggests that centenarians may possess additional longevity genes that help to buffer them against the harmful effects of an unhealthy lifestyle," said senior author Nir Barzilai, director of the Institute for Aging Research at Yeshiva University's Albert Einstein College of Medicine.The study involves 477 Ashkenazi Jews between the ages of 95 and 122, of whom 75 percent are women. According to the study, Ashkenazi Jews are chosen as subjects because they are more "genetically uniform than other populations, making it easier to spot gene differences that are present."The study also found that the long-lived Ashkenazi Jews drank slightly more and exercised less than their average counterparts. But Barzilai also warned: “Although this study demonstrates that centenarians can be obese, smoke and avoid exercise, those lifestyle habits are not good choices for most of us who do not have a family history of longevity.""We should watch our weight, avoid smoking and be sure to exercise, since these activities have been shown to have great health benefits for the general population, including a longer lifespan," He added.

PARIS, Aug. 7 (Xinhua) -- European heavy-lift launcher Ariane 5 lifted off two communication satellites on Saturday.The Ariane 5, carrying Astra 1N and BSAT-3c/JCSAT-110R, was launched at 2252 GMT on Saturday from Kourou launch centre in French Guiana, according to live broadcast of the launching process.This was the fourth mission of Ariane 5 in 2011 and its 203th flight that sent off the two satellites Saturday night to their respective geostationary transfer orbits.Astra 1N, to be separated first, is built by EADS Astrium in Toulouse, France, for the Luxembourg-based operator SES Astra. With a designed lifespan of 15 years, it has an estimated liftoff mass of 5,350 kg and is fitted with 52 active Ku-band transponders.It is initially to deliver interim capacity from an orbital position of 28.2 degree East, and will subsequently move to SES Astra's prime location at 19.2 degree East for primary and backup services.BSAT-3c/JCSAT-110R is manufactured by Lockheed Martin Commercial Space Systems in Newtown, Pennsylvania, for Japanese operators B-SAT Corporation and SKY Perfect JSAT Corporation. This satellite weighs approximately 2,910 kg at launch time. It is to be positioned at 110 degree East longitude in geostationary orbit with a lifetime exceeding 16 years.This Ariane 5 flight has been postponed twice, firstly due to some technical problem in early July and then delayed by bad weather.Arianespace plans to achieve six Ariane 5 missions through this year.

VANCOUVER, Sept. 17 (Xinhua) -- The fourth International Health Qigong Tournament and Exchange kicked off the competition portion of the Vancouver event Saturday to showcase the health benefits of this increasingly popular activity.At a gala opening ceremony in the War Memorial Gymnasium at the University of British Columbia, the biennial tournament was being held outside of China for the first time in an effort to promote the exercise that involves controlled breathing, body postures, movement and mental concentration.The Vancouver tournament has attracted 44 Health Qigong groups from 25 countries and regions, 327 participants in all. The event was last held in Shanghai in 2009.Xiao Min, the All-China Sports Federation vice president, said after three successful events in China, it was important to explore the possibilities of rotating the host venues around the world to boost the exposure of Health Qigong to a wider audience, effectively strengthening the interaction of the Eastern and Western cultures.Calling it "one of the best Chinese traditional sports," Xiao added, "we still have a long way to go in promoting Health Qigong. However, we will try our best to promote it so as to bring health benefits to more people in the world."Sending a message read by Vancouver-based federal politician Wai Young, Canadian Prime Minister Stephen Harper said such a tournament would allow people to "cultivate their interest in and learn more about the benefits of this ancient Chinese healing system.""I would like to commend the organizing committee for putting together a program that promotes cultural exchange and encourages others to embrace Qigong teachings and practices for health, fitness and personal growth. I'm certain that the enthusiasts will make the most of this exciting opportunity and will leave inspired to put what they have learned into practice," wrote Harper, who will be making his second official visit to China later this year.In his speech to the dignitaries and public gathered for the opening ceremony, Liang Shugen, the Chinese Consul General in Vancouver, said it didn't matter who won medals during the competition as everybody participating was a winner."However, it is all the more important that your group build up friendship among the different peoples from different countries, so therefore I wish you all do your best and hope that through this competition you bring the friendship of the Chinese people, of the people from different countries, back to your home country and it is such a course that will be building a harmonious world."With participants representing countries and regions from North America, Europe, Australia, South America, Asia and all over China, which has competitors from 10 provinces, as well as Macau and Hong Kong, the eight-day tournament is providing an extensive overview of what Health Qigong is about.In addition to the two-day competition taking place over the weekend, there is also a referee clinic, a Duan examination and training sessions in the different Health Qigong disciplines, Yi Jinjing, Wu Qinxi, Liu Zijue and Ba Duanjin, among them.Ken Low, who is considered Mr Wushu in Canada, has been instrumental in organizing the Vancouver event. As the president of the Canada International Health Qigong Association he said people need to know about what's involved in the exercise and how it's different from traditional martial arts."It is more than fitness, it's actually mental and physical. It builds inner strength and it builds your, strengthens your joints and muscles and tendons, particularly in your neck area, your shoulders, your spine and your inner organs and your breathing and your focus," he said."So it's not a martial arts, although it is connected somewhat to martial arts because the movements have no self-defence meanings. All the movements are designed to enhance your health."One person who turned to the exercise for health reasons is Diane Hynes. A member of the 12-strong team representing the USA Health Qigong Association, the 50-year-old New Jersey native offers classes in Health Qigong with a cliental of students ranging from five to 84 years.She explained Qigong "helps refine that movement of our eternal energy and makes more as you breathe and move. It has to do with your breath, your ability to relax, bringing your mind to your heart and really moving it out, the energy out to the limbs. That's why it helps with sleep and stress."Hynes, who looked healthy and fit, said she realizes that she is influencing others who want to know what the mother of nine-year-old is doing to look good."And I'm not taking drugs to look well or having surgery," she said, adding the practice is destined to get bigger among westerners as the Baby Boomer generation ages and puts greater emphasis on health. ( "Medication can help for awhile but that takes from you as well, that takes from your energy. This just helps to build energy and move it in your body. Because the thing is, in Chinese medicine, it's about movement, everything's a flow and moving in a circle so it's a give and take."It's a movement and if you are not moving in harmony and you're stuck and stagnant then you are going to be uneasy or diseased or unwell. You're not necessarily sick but you're stuck."

VIENNA, Sept. 9 (Xinhua) -- The three-day Traditional Chinese Medicine (TCM) exhibition opened Friday in the Flower Garden Hirschstetten in Vienna, with the aim to introduce traditional Chinese medicine to the Austrians and to arouse their interest in the culture of Chinese medicine.Holding for the second time, the exhibition this year have attracted more visitors to take part in the health talks on traditional Chinese medicine, read or buy books around the theme of traditional Chinese medicine. Some visitors enthusiastically tried Chinese diet therapy prepared by the organizers.In recent years, traditional Chinese medicine has been increasingly recognized and accepted in Austria. It has already not only entered into the classroom but also into the hospital and clinic.Some private health insurance companies in Austria have started to include the treatment by traditional Chinese medicine into their insuring categories. Chinese patent drugs are already available in many pharmacies in Austria.But in general, traditional Chinese medicine still faces many limits in Austria, which hasn't been involved into the public health insurance system. Some Austrians still have doubts of Chinese medicine, in particular the medicinal herb drugs. All these have restricted the development of traditional Chinese medicine here.Currently, major clinics of traditional Chinese medicine carry out only acupuncture and moxibustion, massage and other health-care physical therapy.Richard Schmerker, a doctor of traditional Chinese medicine in Austria, told reporters that the development of traditional Chinese medicine here still faces many challenges and the biggest one is the shortage of effective propaganda and popularization.But he expressed his full confidence about the future of traditional Chinese medicine in Austria. He said, the uniqueness of finding the root cause of diseases and laying the axe to the root will make it be accepted by more and more Austrians.
