YUEYANG, Hunan, June 2 (Xinhua) -- The population of finless porpoises, an endangered species of freshwater dolphin that lives in China's Yangtze River, may decrease by over 80 percent over the next 30 years, experts said on Thursday after conducting a field survey along the river.The rare species will edge closer to extinction if no action is taken, said Wang Ding, a dolphin expert from the Hydrobiology Institute of the Chinese Academy of Sciences.Wang's team conducted a survey on Poyang Lake, Dongting Lake and other locations along the Yangtze from Sunday to Wednesday this week.The dolphin population currently stands at 1,000, even lower than that of the giant panda, Wang said.The dolphin population is decreasing by a rate of 6.4 percent annually, Wang said."The next ten years will be a critical period for the conservation of this species," Wang said.A long-lasting drought in central China has lowered water levels in many of the region's lakes and rivers, doing great harm to the dolphins' habitat and leading to a decrease in population, Wang said.Mei Zhigang, a member of Wang's survey team, said that human activity has also contributed to the dropping population.Mei said that large numbers of shipping vessels on the Yangtze have impeded the dolphins' migration path, causing them to reproduce less frequently.

BEIJING, Sept. 28 (Xinhuanet) -- The unmanned Shenzhou VIII, part of China's first spacecraft rendezvous and docking mission, will be launched in early November. Niu Hongguang, deputy commander-in-chief of the program, said on Tuesday the launch has not been affected by the postponed lift-off of the Tiangong-1 space module. Tiangong-1 was to enter a low orbit around Earth at the end of August before being met by Shenzhou VIII. However, the departure was pushed back after a satellite failure on Aug 18. Out of safety concerns, Niu said mission commanders ordered a halt to testing at Jiuquan Satellite Launch Center on Tiangong-1 and its carrier rocket, Long March II-F T1. China Aerospace Science and Technology Corp, which designed and made the rocket carrier that failed to launch, formed an expert panel to investigate and made modifications. A successful launch of a communication satellite on Sept 19 using the Long March II-C showed the measures worked, Niu said, adding: "We now have confidence in the launch of Tiangong-1." The module is a "simplified" space lab that will not only be a docking target, but will also work as a space experimental platform. It will be unmanned for most of its two years of use, although astronauts will spend time onboard for short periods. After Shenzhou VIII, the country will launch Shenzhou IX and Shenzhou X next year to rendezvous and dock with Tiangong-1. Niu confirmed Shenzhou X will be manned. Tiangong-1 can accommodate two to three astronauts. "Whether Shenzhou IX will be manned is up to the results of the first rendezvous and docking mission," he said. The rocket carrier with Tiangong-1 atop stands 52 meters tall, with a takeoff weight of 493 tons. Tiangong-1 was scheduled for launch in between Sept 27 and 30, but due to weather forecasts that predicted a cold air mass would move into the area of Jiuquan Satellite Launch Center, it is believed that conditions on Thursday and Friday will be suitable for takeoff.

SYDNEY, July 1 (Xinhua) -- Breastfeeding mothers should limit their use of codeine-containing painkillers to four days as they can cause harm, an Australian doctor warned on Friday.The warning is being discussed at a meeting of anesthetists in Sydney."New mothers should limit their use of codeine-containing painkillers to no more than four days and, if they feel drowsy while taking this medication, cease its use and have their baby examined by a doctor for signs of drowsiness," Sydney's Royal North Shore Hospital anesthetist Dr. Gavin Pattullo said."This is because codeine needs to be metabolized by the liver into morphine to offer pain relief and this liver conversion process is very unpredictable," Pattullo said."Some patients' livers produce large amounts of morphine after taking codeine, causing drowsiness, while others fail to produce any morphine at all."Pattullo said for breastfeeding mothers, a large dose of morphine could make its way into the baby and result in the baby's death by overdose."While new mums shouldn't be unnecessarily alarmed, they need to be aware that codeine-containing painkillers in certain circumstances can cause harm," he said.Breastfeeding mothers are being advised to see a doctor if their baby gets sleepy while taking the painkillers.

CANBERRA, Sept. 6 (Xinhua) -- A rare virus that can be contracted by humans has killed a large number of Victorian pigeons after being detected in the Australian state for the first time, Agriculture Department confirmed on Tuesday.According to the Australian Chief Veterinary Officer, Dr Mark Schipp, the avian paramyxo virus has already started killing some hobby birds, and threatens to spread to Victoria's chicken population.He said the affected birds have died suddenly in large numbers and have sometimes appeared tired or have shown neurological signs such as circling or head flicking before death.He added that the bug can also cause conjunctivitis or influenza-like symptoms in humans."The virus causes only mild, short-term conjunctivitis or influenza-like symptoms (in humans)," Australia Associated Press quoted Schipp as reporting on Tuesday."Human infection with this virus is extremely rare and usually occurs only in people who have close direct contact with infected birds."At this stage, there are no reports of the virus causing disease in wild birds, but the Australian Wildlife Health Network has been asked to monitor the situation.

BERLIN, June 9 (Xinhua) -- A 57-year-old man died of E. coli infection in Germany's Frankfurt Thursday, pushing the death toll from the bacteria to 30.The man had traveled with his wife to the city of Hamburg, an epicenter of the outbreak, Frankfurt authority said.Another two deaths were reported in the state of Lower Saxony, including a 68-year-old man and a 20-year-old woman, while more than 2,800 people in 14 countries have been infected since the deadly E. coli outbroke.German researchers detected again the deadly strain o104 of E. coli on the scraps of cucumbers in a dustbin in the eastern city of Magdeburg in the state Saxony-Anhalt on Wednesday.German health minister Daniel Bahr expressed his cautious hope for the disease on Wednesday as the number of new infection is clearly going down.But he also admitted there will be new cases and more deaths have to be expected, as Germany's national disease control centre, the Robert Koch Institute reported more than 300 infection in Germany on the same day.The Robert Koch Institute also noticed the declining trend in new cases but it was not clear whether this was caused by people staying away from vegetables or the outbreak was truly waning.
