CHANGCHUN, Nov. 13 (Xinhua) -- An infrared camera set up by the World Wildlife Fund (WWF) and forestry authorities in northeast China's Jilin province has captured images of a wild Siberian tiger in the Wanda Mountains.Zhu Jiang, head of the WWF Northeast China Program Office, said Saturday that the photos, taken earlier this month, are the first images of a wild Siberian tiger taken in the mountainous area.He said the evidence consolidates the mountains' role as an important habitat for the endangered species, and reinforces the need for local authorities to tighten protection measures, especially clearing animal traps and improving animal rescue efforts.The agency estimates that there are fewer than 20 wild Siberian tigers remaining in China. They live in mountains in the northeastern Heilongjiang and Jilin provinces.Zhu said animal traps still pose a major threat to the safety of wild Siberian tigers and their prey.A wild Siberian tiger was found dead with a trap around its neck in the city of Mishan, Heilongjiang, in October.A WWF survey found an average of 1.6 traps for every 10 km of distance covered in the Siberian tiger nature reserves in Heilongjiang and Jilin last winter."The WWF hopes to cooperate with local governments to protect Siberian tigers and restore their habitats," Zhu told Xinhua. "We aim to help double the population of wild Siberian tigers in China by 2022, the next Year of the Tiger," he said.

CANBERRA, Dec. 9 (Xinhua) -- Scientists from Australia's University of New England on Friday said they had discovered the remarkably fossil isa metre-long arthropod with excellent vision called anomalocaris from Emu Bay Shale of South Australia.The scientists reported their finding on the anomalocaris in thescience journal Nature this week.It is reported that anomalocaris is a fearsome ancient predator that swam in the Cambrian oceans 500 million years ago. The researchers said the presence of anomalocaris would have driven the development of protective adaptations in prey animals. Such an escalatory 'arms race' would have seen, for instance, the evolution of such adaptations in prey as shells, camouflage and burrowing into sediments. "It has been unbelievably frustrating being able to see eyes like these at fossil sites like the Burgess Shale (in the Canadian Rocky Mountains), but not have any details. It is really refreshing to have our ideas about these animals confirmed at last, " comments Simon Conway Morris, a palaeontologist at the University of Cambridge, the United Kingdom.The research team was led by paleontologist Dr John Paterson, of the University of New England. He said the most surprising discovery of anomalocaris is the huge number of tiny hardened lenses in each eyes."When you consider that a modern housefly, for example, has about 3000 lenses, it's pretty impressive that an animal half a billion years old already has remarkable vision like this," Paterson said in statement."The fact that each eye in anomalocaris would have had over 16, 000 lenses means it would have very, very good resolution."Paterson said the acute vision of Anomalocaris gave it a distinct advantage over competing predators and prey, as many Cambrian animals either had poor vision or were completely blind. Its acute vision rivals or exceeds that of most living insects and was probably comparable to predatory dragonflies today.He said their findings support the idea that compound eyes evolved very early on in arthropod evolution, before the evolution of jointed legs or hardened exoskeletons.The research team hopes they can find the more fossil remains of Cambrian creatures in the Emu Bay Shale.

BEIJING, Nov. 24 (Xinhua) -- In response to public suspicion stoked by recent dumpling contamination scandals, China's Ministry of Health on Thursday said the new food safety standard for flash-frozen dumplings did not show signs of leniency.The Ministry introduced the new food safety standard on flash-frozen dough or rice products on Thursday.The Ministry has been accused of loosening scrutiny over a disease-generating bacteria in such foods, staphylococcus aureus, or golden staph, which can cause various diseases, including pneumonia and sepsis, and is sometimes life-threatening.The controversy became particularly relevant after several major brands of frozen dumplings have been successively recalled in recent months.In October, a Henan-based company, Zhengzhou Sinian Food Co., Ltd, confirmed the contamination of golden staph in its flash-frozen seafood- and pork-stuffed dumplings.Frozen dumplings made by Hong Kong-based manufacturer Wanchai Ferry were found to contain golden staph in November, and some of its products have been pulled from shelves.The previous standard provided that no golden staph should be tested in such food, while the new one gives a quantitative restriction that the volume of the bacteria should be no more than ten to the fourth degree.Liu Xiumei, a food safety expert with the Chinese Center for Disease Control and Prevention, said at the press conference held by the health ministry that such bacteria becomes inactivate after the food is boiled for a few seconds, and it takes a volume of ten to the fifth degree to generate toxicity.The previous standard could only serve as a general provision due to the lack of quantitative microbiological testing back when it was introduced, Liu said, stressing that the new standard is not a sign that the Ministry has gone soft on bacterial contamination of relevant foods.The new standard will come into effect starting Dec. 21, 2011.

BEIJING, Oct. 24 (Xinhuanet) -- There is no evidence to prove that using a cell phone can increase the risks of brain cancer, suggested a lastest study by Danish researchers.To arrive at the result, the researchers examined the health records from 1990 to 2007 for 358,403 Danish cell phone plan subscribers.They found that among people using cell phones for as long as 13 years or more, the cancer risks were almost the same as for non-subscribers.The finding, published in the British Medical Journal last week, alleviated the fear among the world's 5 billion cell phone users.Five months ago, a statement from the World Health Organization's International Agency for Research on Cancer (IARC) sparked fear in cell phone users around the world because it said that cell phone use might cause brain cancer.However, the finding could not rule out the risk of brain cancer triggered by heavy use of cell phones, admitted Patrizia Frei of the Danish Cancer Society's Institute of Cancer Epidemiology, lead author of the study.Frei added, cited by CNN, "There are still some open questions, about greater amounts of use, and about the effects on children."The IARC did not give formal response to the study, but it offered some ways for cell phone consumers to reduce possible risks months ago.Texting and using hands-free sets for voice calls lower exposure to potentially harmful radiation, compared to device-to-ear voice calls, by at least 10-fold, IARC stated, reported by the New York Daily News.

WASHINGTON, Nov. 14 (Xinhua) -- Nearly a fifth of all Americans 12 years or older have hearing loss so severe that it may make communication difficult, according to a new study led by Johns Hopkins University researchers and published Monday in the Archives of Internal Medicine.The findings, thought to be the first nationally representative estimate of hearing loss, suggest that many more people than previously thought are affected by this condition.Study leader Frank Lin, an assistant professor, and his colleagues used data from the National Health and Nutritional Examination Surveys (NHANES), a research program that has periodically gathered health data from thousands of Americans since 1971. The researchers analyzed data from all participants age 12 and over whose hearing was tested during NHANES examinations from 2001 to 2008. Unlike previous estimates, NHANES includes men and women of all races and ages, from cities scattered across the country, so it's thought to statistically mimic the population of the Untied States.Using the World Health Organization's definition for hearing loss (not being able to hear sounds of 25 decibels or less in the speech frequencies), the researchers found that overall, about 30 million Americans, or 12.7 percent of the population, had hearing loss in both ears. That number jumps to about 48 million, or 20.3 percent, for people who have hearing loss in at least one ear. These numbers far surpass previous estimates of 21 to 29 million.Hearing loss prevalence nearly doubled with every age decade, with women and blacks being significantly less likely to have hearing loss at any age. Lin and his colleagues aren't sure why these groups appear to be protected. However, he notes that the female hormone estrogen, as well as the melanin pigment in darker skin, could have a protective effect on the inner ear.
