SAN FRANCISCO, July 28 (Xinhua) -- Amazon announced Thursday that it had reached an agreement with NBC Universal to allow its members to view certain movies from Universal Pictures on-line through its movie streaming service.According to the on-line retail giant, Oscar-winning movies such as "Eternal Sunshine of the Spotless Mind," "Gosford Park" and "Elizabeth" as well as other favorites like "Notting Hill" and "Billy Elliot" are part of the pact.The movies will be available to Amazon Prime members through its streaming service Prime Instant Video. Amazon Prime is a membership program that gives subscribers discounts on shipping for a 79 U.S. dollar annual fee.In February, Amazon said it would offer Prime customers unlimited access to an on-line video library. Last Wednesday, Amazon announced an accord with CBS that expanded the video library to more than 8,000 movies and TV shows. It said Thursday that the NBC deal will bring the number to more than 9,000.With the CBS, NBC Universal deals, Amazon steps up its rivalry against other movie streaming services, especially Netflix, a popular on-line and mail-order movie rental company which just boosted prices by 60 percent for some subscribers. Analysts said Amazon is trying to make the pitch to those customers who are disappointed with Netflix.In a second-quarter earnings letter to investors distributed on Monday, Netflix CEO Reed Hastings said Netflix had more than 24.6 million subscribers in the U.S. at the end of June and vastly more streaming content than its competitors."We haven't detected an impact on our business from Amazon Prime," he noted.

WASHINGTON, Aug. 3 (Xinhua) -- The annual number of new HIV infections in the United States was relatively stable at approximately 50,000 new infections each year between 2006 and 2009, the Centers for Disease Control and Prevention's first multi- year estimates from its national HIV incidence surveillance find.However, HIV infections increased among young men who have sex with men (MSM) between 2006 and 2009, driven by alarming increases among young, black MSM -- the only subpopulation to experience a sustained increase during the period.According to the new estimates, there were 48,600 new HIV infections in the United States in 2006, 56,000 in 2007, 47,800 in 2008 and 48,100 in 2009. The multi-year incidence estimates allow for a reliable examination of trends over time. They reveal no statistically significant change in HIV incidence overall from 2006 to 2009, with an average of 50,000 for the four-year period. In 2009, the largest number of new infections was among white MSM (11,400), followed closely by black MSM (10,800). Hispanic MSM (6, 000) and black women (5,400) were also heavily affected.The new estimates were published Wednesday in the on-line scientific journal PLoS ONE."More than 30 years into the HIV epidemic, about 50,000 people in this country still become infected each year. Not only do men who have sex with men continue to account for most new infections, young gay and bisexual men are the only group in which infections are increasing, and this increase is particularly concerning among young African American MSM," said CDC Director Thomas Frieden. " HIV infections can be prevented. By getting tested, reducing risky behaviors, and getting treatment, people can protect themselves and their loved ones."

WASHINGTON, July 15 (Xinhua) -- Coastal communities along the U. S. East Coast may be at risk to higher sea levels accompanied by more destructive storm surges in future El Nino years, according to a new study published Friday by the U.S. National Oceanic and Atmospheric Administration (NOAA).The study was prompted by an unusual number of destructive storm surges along the East Coast during the 2009-2010 El Nino winter.The study, led by Bill Sweet, from NOAA's Center for Operational Oceanographic Products and Services, examined water levels and storm surge events during the "cool season" of October to April for the past five decades at four sites representative of much of the East Coast: Boston, Atlantic City, Norfolk and Charleston.From 1961 to 2010, it was found that in strong El Nino years, these coastal areas experienced nearly three times the average number of storm surge events (defined as those of one foot or greater). The research also found that waters in those areas saw a third-of-a-foot elevation in mean sea level above predicted conditions."High-water events are already a concern for coastal communities. Studies like this may better prepare local officials who plan for or respond to conditions that may impact their communities," said Sweet. "For instance, city planners may consider reinforcing the primary dunes to mitigate for erosion at their beaches and protecting vulnerable structures like city docks by October during a strong El Nino year."El Nino conditions are characterized by unusually warm ocean temperatures in the Equatorial Pacific that normally peak during the Northern Hemisphere "cool season." They occur every three to five years with stronger events generally occurring every 10-15 years. El Nino conditions have important consequences for global weather patterns, and within the U.S., often cause wetter-than- average conditions and cooler-than-normal temperatures across much of the South.

WASHINGTON, July 20 (Xinhua) -- Using the Hubble Space Telescope, astronomers have discovered a fourth moon orbiting the icy dwarf planet Pluto, the U.S. National Aeronautics and Space Administration (NASA) announced Wednesday in a statement. The tiny, new satellite, temporarily designated P4, was uncovered in a Hubble survey searching for rings around the dwarf planet.P4 was first seen in a photo taken with Hubble's Wide Field Camera 3 on June 28. It was confirmed in subsequent Hubble pictures taken on July 3 and July 18. It is the smallest moon discovered around Pluto. It has an estimated diameter of 8 to 21 miles (13 to 34 km). By comparison, Charon, Pluto's largest moon, is 648 miles (1,043 km) across, and the other moons, Nix and Hydra, are in the range of 20 to 70 miles in diameter (32 to 113 km).Two labeled images of the Pluto system taken by the Hubble Space Telescope's Wide Field Camera 3 ultraviolet visible instrument with newly discovered fourth moon P4 circled. The image on the left was taken on June 28, 2011. The image of the right was taken on July 3, 2011."I find it remarkable that Hubble's cameras enabled us to see such a tiny object so clearly from a distance of more than 3 billion miles (5 billion km)," said Mark Showalter of the SETI Institute in California, who led this observing program with Hubble.P4 is located between the orbits of Nix and Hydra, which Hubble discovered in 2005. Charon was discovered in 1978 at the U.S. Naval Observatory and first resolved using Hubble in 1990 as a separate body from Pluto.The dwarf planet's entire moon system is believed to have formed by a collision between Pluto and another planet-sized body early in the history of the solar system. The smashup flung material that coalesced into the family of satellites observed around Pluto.The finding is a result of ongoing work to support NASA's New Horizons mission, scheduled to fly through the Pluto system in 2015. The mission is designed to provide new insights about worlds at the edge of our solar system. Hubble's mapping of Pluto's surface and discovery of its satellites have been invaluable to planning for New Horizons' close encounter."This is a fantastic discovery," said New Horizons' principal investigator Alan Stern of the Southwest Research Institute in Colorado. "Now that we know there's another moon in the Pluto system, we can plan close-up observations of it during our flyby."

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."
