KATHMANDU, Aug. 3 (Xinhua) -- Two glaciers in Nepal that shrank at an accelerated rate in the past 10 years compared to preceding decades will inevitably disappear from rising temperatures as no fresh snow supply is expected for them, a new research by Japan's Nagoya University says.According to Wednesday's Republica daily, the masses of the Yala glacier of Langtang Himal in central Nepal and the AX010 glacier of Shorong Himal in the Khumbu region shrank annually by 0. 8 meters and 0.81 meters respectively in the 2000s, which was a significant acceleration from the 0.68 and 0.72 meters of shrinkage per year between 1970 and 1990, said findings of the research published in a journal of the National Academy of Sciences of the United States on Tuesday."If the trend since the 1990s continues for the Yala and AX010 glaciers, the disappearance of these glaciers is inevitable because they are about to lose their accumulation areas, thus, no snow supply is expected for these glaciers," says the research conducted by Koji Fujita and Takayuki Nuimura.The researchers also found that while the shrinking of glaciers has accelerated in humid environments, the opposite is true for those in arid environments. The shrinking of Rikha Samba glacier located in the Kaligandaki Hidden Valley slowed from 0.57 meters per year between 1970 and 1990 to 0.48 meters per year in the 2000s."A comparison of the mass balance results and annual precipitation reveals that glacier wastage has been accelerated in humid environments but suppressed in an arid environment," the research says.Apart from environment, altitude also appears to play a role in the lifespan of glaciers, the researchers say. Rikha Samba is located at an altitude of 5,700 meters where loss of mass from melting could be compensated to some extent by collection of snowfall.The Yala glacier and AX010, on the other hand, are located at lower altitudes of 5,400 meters and 5,200 meters respectively.
LOS ANGELES, May 30 (Xinhua) -- The American Academy of Pediatrics (AAP) warned on Monday that children should keep away from energy drinks which may be dangerous for minors.The AAP urged young children and teens to avoid energy drinks entirely, saying routine consumption of sports drinks should be limited or eliminated.Energy drinks include such popular brands as Red Bull, AMP and Rockstar, the AAP said in a report.These drinks, the report said, tend to be heavily caffeinated, potentially having several times the level of caffeine found in a cup of coffee.In addition, manufacturers often add sugar and herbal stimulants such as guarana and taurine to the drinks, which are popular among kids, according to the report."There's no place for energy drinks for kids," said report co-author Dr. Marcie Beth Schneider, an adolescent physician in Greenwich, Connecticut. "There's a place for sports drinks, but that place is very specific."The caffeine in energy drinks can lead to high blood pressure, high heart rate and insomnia, she said.The other ingredients can boost the power of the caffeine, she said, adding that the drinks will have a greater effect on children because they're smaller than adults."Kids don't need to have this," she said. "This is not something they should be drinking."Schneider declined to identify any energy drinks that may be better than others for kids who insist on drinking them. If kids use energy drinks because they're tired, she said, they should get more rest instead of chugging caffeine.Half of the nation's 5,448 reported caffeine overdoses in 2007 were in people under age 19, although it's not known how many of the cases were the result of energy drink consumption, according to statistics provided by the AAP.

SAN FRANCISCO, June 13 (Xinhua) -- Google on Monday confirmed that it had signed an agreement to buy Admeld, an on-line advertising optimization firm, in a deal seen as the Internet search giant's latest move to bolster its on-line display ad business.Admeld, launched in 2007 and headquartered in New York City, has developed a service that can help on-line publishers manage their ad space more efficiently and profitably.Admeld now has more than 500 customers worldwide, among them are FOX News, IDG TechNetwork, Discovery and The Weather Channel, according to information posted on its website."By combining Admeld's services, expertise and technology with Google's offerings, we're investing in what we hope will be an improved era of flexible ad management tools for major publishers, " Neal Mohan, Google's vice president of display advertising, said in a blog post announcing the deal."We believe that this investment will be an important step to help on-line publishers, and will further improve and grow the display advertising industry as a whole," Mohan noted.On-line display ads usually appear in forms that consist of images and may be interactive. According to the Interactive Advertising Bureau, a U.S. trade association, display-related on- line ad revenue in the United States totaled nearly 10 billion U.S. dollars in 2010.Financial terms of the deal were not disclosed by the two companies. TechCrunch, a technology blog site, has reported that Google paid around 400 million dollars.
WASHINGTON, May 30 (Xinhua) -- After nearly 12 days together in orbit, U.S. space shuttle Endeavour undocked from the International Space Station on Sunday night, NASA announced on Monday.According to NASA, the undocking took place at 11:55 p.m. EDT ( 0355 GMT Monday) as the spacecraft sailed 215 miles (346 km) above Bolivia.Pilot Greg Johnson, at the aft flight deck controls, flew Endeavour in a circle around the station at distances of about 450 to 650 feet. Crew members took still and video images of the station.The Space Shuttle Endeavour is seen as it departs the International Space Station after undocking in this image from NASA TV May 29, 2011.As Johnson was about to begin the flyaround, Commander Mark Kelly radioed mission control that he could see the two-billion-U. S.-dollar Alpha Magnetic Spectrometer (AMS) particle physics detector Endeavour had brought to orbit. "It's a new day for science on the space station," he said to mission control.The AMS will be left at the space station to scour the universe for clues about dark matter and antimatter. Endeavour is scheduled to land at the Kennedy Space Center at 2:35 a.m. (0635 GMT) on Wednesday.During their stay at the space station, the Endeavour crew conducted four spacewalks to complete construction of the U.S. side of the 100-billion-dollar outpost, a project of 16 nations that has been being assembled in orbit since 1998.They also brought up a logistics carrier with spare parts and performed some maintenance and installation work during the four spacewalks, the last to be carried out by an American shuttle crew.NASA plans to decommission Endeavour, its youngest shuttle with 25 voyages, and send it to a museum in Los Angeles for display.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 space station.
BEIJING, Aug. 16 (Xinhuanet) -- Almost one in four Chinese students aged between 12 and 14 have tried smoking, according to the results of a survey released by the Chinese Association on Tobacco Control (CATC).The survey, carried out among 38,839 students and 6,503 teachers from middle and high schools in 11 provinces across the country between May and June, showed that 22.5 percent of students aged between 12 and 14 had tried smoking and that 15.8 percent of middle and high school students smoke regularly."There are definitely quite a number of boy students in my class who smoke regularly as some have been found smoking outside campus during lunch break," said Li Xiaolan, an English teacher from a high school in Shanghai. The survey also found that 39 percent of students took their first cigarette from their classmates."It was quite common to smoke with my classmates at school and we usually smoked in toilets or in corners of the playground after lunch," said Zhou Guangrong, a 22-year-old university student from Guiyang, Guizhou province, who started smoking when he was 12.The majority of student smokers buy cigarettes themselves and about 76 percent of the adolescent smokers said that there is at least one cigarette shop within 200 meters from their school."When I was a student at middle and high schools, they were surrounded by cigarette shops," said Zhou who used to smoke two cigarettes per day in primary school and two packs per week in middle and high school."We're keen to show that more adolescents are starting smoking much younger than before, and that we need to minimize the number of young smokers," said Duan Jiali, secretary-general of the youth tobacco control commission under CATC. Duan added that teachers and parents should set a good example for teenagers by not smoking in front of them at school or at home, which is the most influential way of stopping adolescents from smoking.China banned smoking in 16 types of public indoor venues - including hospitals, schools, bars, restaurants and hotels - on May 1 in an attempt to curb tobacco use in the country with the world's largest number of smokers.Currently, there are more than 300 million smokers in China, and about 1.2 million people die from smoking-related diseases every year, accounting for one-fifth of the world's total, according to statistics from the World Health Organization."Meanwhile, about 540 million people are exposed to secondhand smoke, 48.9 percent of which are adolescents (from 15 to 19 years old)," said Xu Guihua, deputy director of the CATC."It's essential and urgent for us to control the number of adult smokers who potentially tempt adolescents to smoke."
