He also said that China's track record of sharing knowledge with the World Bank was creating a "catalyst for consensus" and that placed the institutions in good stead to benefit from China's economic consistence."The Chinese policy mix includes a tool box of administrative measures ... In general, one of the lessons that the United States and others can learn (from China) is that to have supervisory policies for bank regulatory systems can be a useful part of the tool set."Aside from hinting that over-heating global real estate markets could benefit from China's regulatory tightening, Zoellick suggested if China moved to more market-exposed decision making, he hoped China's bank regulators would not step too far back."Over time China will be better served to move to more precise and market signals than more administration-based decisions. Over time China will want to move to more market based decisions ... but I don't want this to be interpreted that supervisors don't have to supervise," he said.

WASHINGTON, July 5 (Xinhua) -- The countdown for the final space shuttle launch began Tuesday afternoon, but unfavorable weather may delay shuttle Atlantis' launch attempt on Friday, NASA announced."We are going with a 60 percent chance of KSC (Kennedy Space Center) weather prohibiting launch due to the potential for showers and isolated thunderstorms in the area," shuttle weather officer Kathy Winters told reporters Tuesday at a precountdown status briefing. "I wish I had a better weather briefing for you."Atlantis is scheduled to lift off at 11:26 am (1526 GMT) on Friday from Kennedy Space Center with four U.S. astronauts on board for a 12-day mission to the International Space Station. Overall, the chance of an on-time liftoff is 40 percent, Winters said."We will do everything we can to launch on Friday but if things don't work out so that we can do that we have plenty of options... Saturday and Sunday," said NASA Test Director Jeremy Graeber. Conditions improve for Atlantis launch opportunities on Saturday and Sunday.NASA said it must launch Atlantis by Sunday, otherwise it will have to wait until at least July 16. That's because of an unmanned rocket due to lift off next week, using the same launch support personnel and equipment.NASA's 30-year-old shuttle program is ending due to high operating costs. The Obama administration wants to spur private companies to get into the space taxi business, freeing NASA to focus on deep space exploration and new technology development.When the U.S. space shuttle program officially ends later this year, the Russian space program's Soyuz capsule will be the only method for transporting astronauts to and from the station.

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. 30 (Xinhua) -- China's second moon orbiter, the Chang'e-2, has arrived in outer space about 1.5 million km away from Earth and is now orbiting the second Lagrange Point (L2), where gravity from the sun and Earth balances the orbital motion of a satellite, Chinese scientists said Tuesday.Chang'e-2 entered L2's orbit at 11:27 p.m. last Thursday after spending 77 days traveling away from its previous orbital path around the moon, according to the State Administration of Science, Technology and Industry for National Defence (SASTIND).The SASTIND said that China is now the world's third country or organization to successfully put a spacecraft into orbit around L2, after the European Space Agency (ESA) and the National Aeronautics and Space Administration (NASA) of the United States.The Chang'e-2 orbiter will carry out exploration activities around L2 in the coming year, SASTIND said.There are five so-called "Lagrange Points" about 1.5 million km way from the Earth in the exact opposite direction from the sun. Putting a spacecraft at any of these points allows it to stay in a fixed position relative to the Earth and sun with a minimal amount of energy needed for course correction.The orbiter completed all of its assigned tasks after blasting off on Oct. 1, 2010, according to the SASTIND. Although the orbiter was only supposed to remain in space for six months, the SASTIND decided to assign additional tasks to it, as it still had fuel in its reserve tanks.Traveling into outer space from the moon's orbit was one of the orbiter's most important missions, according to the SASTIND.Before arriving at its current position in outer space, the Chang'e-2 took photos of the northern and southern poles of the moon. It then descended to a lower orbit, approximately 15 km away from the moon's surface, where it captured high-resolution images of the Sinus Iridum, or "Bay of Rainbows," an area where future moon probes may land.The SASTIND is reportedly planning to launch measure and control stations into outer space by the end of the second half of next year. The Chang'e-2 will be used to test the two stations' functionality at that time.China's ambitious three-stage moon mission will include a moon landing, as well as the launch of a moon rover during the second stage, which is scheduled to take place in 2012. During the third phase, another rover will land on the moon and return to Earth with lunar soil and stone samples for scientific research around 2017.China does not currently have a timetable in place for a manned moon landing. It launched its first lunar probe, the Chang'e-1, in October 2007.In 2003, China became the third country after Russia and the United States to send a human into space. Two more manned space missions followed, the most recent of which took place in 2008.0 The Chang'e probes are named after the Chinese legendary goddess of the moon.
