LOS ANGELES, April 20 (Xinhua) -- Hundreds of homes were evacuated on Wednesday in Monument, U.S. state of Colorado after hydrochloric acid was leaking from a train car, authorities said.The leak was first reported around 1 a.m. local time when a southbound train spotted a vapor trail on a northbound train, the Denver Post reported.Authorities first ordered the evacuation of some 255 homes, and later expanded the evacuation to an additional 160 homes, according to the report.Schools in the area were closed due to the leaking, the report said.A specialized crew from Texas has been dispatched to the scene to transfer the hydrochloric acid leaking from the train car and is expected to finish the job in four or five hours, weather permitting, the report quoted Sgt. Mike Schaller of the El Paso County Sheriff's Office as saying.The leak is contained but hydrochloric acid is still leaking slowly from the tanker, which holds 25,000-30,000 gallons, Schaller said.He said police went door-to-door notifying residents of a subdivision adjacent to the railroad tracks to evacuate as a precaution.No injuries have been reported, he said, but residents have been warned that they may have to be out of their homes until Friday as hazardous material crews offload the acid to another container.The northbound train originated in Kansas and was en route to Denver at the time, the Denver Post said.It's not yet known how much hydrochloric acid leaked from the train car.Once the leak is sealed, crews will remove the hydrochloric acid from the damaged car to a new car that will likely continue into Denver, according to the report.Monument is a town of 3,230 residents 88 kilometers south of Denver.

ISTANBUL, May 3 (Xinhua) -- The world's water consumption will increase by 40 percent over the next two decades and efforts to meet this demand must increase radically, the secretary-general of the 5th World Water Forum said here on Tuesday.Oktay Tabasaran said in his opening speech at the World Water Forum that "water consumption will increase by 40 percent in the coming 20 years, reaching 6.9 trillion cubic meters per year ( compared with the 4.5 trillion used currently), and an amount of 200 billion U.S. dollars must be spent annually in order to afford this."He said such figures indicated the urgent need for countries to engage in efficient cooperation with each other to address water- related issues.Some 50 out of the world's 188 countries have serious concerns in providing drinking and irrigation water, due to careless and inefficient use of water, according to Ismail Ugur, the general director of Turkey's State Waterworks Authority."If we fail to come up with solutions, starting from 2015 there will be droughts (in many parts of the world) and people will start suffering from diseases caused by lack of water, as of 2025, " Ugur said.Ekmeleddin Ihsanoglu, head of the Organization of the Islamic Conference (OIC), said that ensuring reliable access to water is crucial to promoting peace and security in the Middle East, where many countries are facing dramatic declines in available water."In some regions of the Muslim world, water availability is predicted to be cut in half by 2050, even without taking into consideration the effects of climate change," he said in his opening speech.The OIC chief called for increased cooperation among member states and countries outside the region, announcing the group's progress in preparing its own "Water Vision" document and forming an OIC Water Council to address water-related concerns."In its first phase, the Water Vision will outline a framework of cooperation on water-related issues in terms of water-sharing experience, capacity development, technology transfer, water governance and institutional reforms," Ihsanoglu said.He cited the Friendship Dam, to be constructed on the Orontes River at the Turkish-Syrian border, as an excellent example of cooperation and peace among neighboring countries in the field of water.Charity Ngilu, minister for water and irrigation of Kenya, stressed the importance of water in promoting peace, especially in regions where water scarcity prevails."There have been many conflicts caused by water scarcity not only among African countries, but even within regions of the same country," She said, adding Kenya would ask Turkey for cooperation and assistance in water management and other related issues.

BEIJING, Jan. 26 (Xinhua) -- The Chinese government Wednesday raised the minimum down payment requirement for the purchase of second home to 60 percent of the property's value from 50 percent, to curb property market speculation.The decision was announced in a statement released after an executive meeting of the State Council, China's cabinet, which was presided over by Premier Wen Jiabao.File photo taken on Nov. 14, 2010 shows a newly built residential community in east China's Shanghai Municipality.

BEIJING, March 24 (Xinhuanet) -- Mozilla's newly launched Firefox 4 Web browser was downloaded nearly 7 million times worldwide in the first 24 hours, according to media reports.The number was almost triple the 2.4 million downloads that Microsoft reported in the first 24 hours after the Internet Explorer 9 (IE9) was released.Nevertheless, the number lagged behind the record-breaking performance of Firefox 3, which was downloaded more than 8 million times in the first day after launch in mid-2008.Statistics show that Firefox 4 has attracted interest from around the world, with 44 percent downloads in Europe, 26 percent in North America. and 20 percent in Asia.Mozilla launched Firefox 4 on Tuesday at around 10:00 a.m. EDT to compete with Microsoft's IE9 and Google Chrome.The new Web browser was originally scheduled to ship last November, but bugs delayed the release into early this year.Firefox trumped IE9 in the first day download contest because it runs on Windows XP, the 10-year-old operating system that IE9 doesn't support.

WASHINGTON, April 5 (Xinhua) -- NASA and co-researchers from the United States, the Republic of Korea and Japan have found a new mineral named "Wassonite" in one of the most historically significant meteorites recovered in Antarctica in December 1969, the U.S. space agency said on Tuesday in a statement.The new mineral was discovered within the meteorite officially designated Yamato 691 enstatite chondrite. The meteorite likely may have originated from an asteroid orbiting between Mars and Jupiter. Wassonite is among the tiniest, yet most important, minerals identified in the 4.5-billion-year-old sample.The research team, headed by NASA space scientist Keiko Nakamura-Messenger, added the mineral to the list of 4,500 officially approved by the International Mineralogical Association."Wassonite is a mineral formed from only two elements, sulfur and titanium, yet it possesses a unique crystal structure that has not been previously observed in nature," said Nakamura-Messenger.In 1969, members of the Japanese Antarctic Research Expedition discovered nine meteorites on the blue ice field of the Yamato Mountains in Antarctica. This was the first significant recovery of Antarctic meteorites and represented samples of several different types.As a result, the United States and Japan conducted systematic follow-up searches for meteorites in Antarctica that recovered more than 40,000 specimens, including extremely rare Martian and lunar meteorites.Researchers found Wassonite surrounded by additional unknown minerals that are being investigated. The mineral is less than one-hundredth the width of a human hair or 50x450 nanometers. It would have been impossible to discover without NASA's transmission electron microscope, which is capable of isolating the Wassonite grains and determining their chemical composition and atomic structure."More secrets of the universe can be revealed from these specimens using 21st century nano-technology," said Nakamura- Messenger.The new mineral's name was approved by the International Mineralogical Association. It honors John T. Wasson, professor at the University of California, Los Angeles. Wasson is known for his achievements across a broad swath of meteorite and impact research, including the use of neutron activation data to classify meteorites and to formulate models for the chemical makeup of bulk chondrites.
