BEIJING, May 10 (Xinhuanet) -- YouTube is adding more than 3,000 mainstream movies to its movie-rental service, media reports said Tuesday.Google Inc-owned YouTube is offering a mix of recent Hollywood blockbusters, independent and foreign movies for 99 cents up to 3.99 U.S. dollars each.The additions will push YouTube’s total movie rentals available to more than 6,000.In addition, hundreds of movies, including some offered before the latest launch, are available for free viewing as with other clips.“By expanding our content partnerships worldwide and stimulating the success of budding filmmakers, artists and entrepreneurs, we’ll ensure that YouTube remains the best place for the world to see and discover rich talent,” Salar Kamangar, head of YouTube, said.YouTube, which built a following by letting users post home videos and amateur clips, is counting on professionally produced content to draw more visitors and keep them on the site longer.YouTube users currently spend about 15 minutes on the site per day on average, compared with the five hours they spend on television, the company said.

BEIJING, Feb. 4 (Xinhua) -- The Chinese government Friday initiated a relief and assistance program for eight drought-ravaged provinces, said a statement on the website of Ministry of Agriculture.The government had implemented a grade II emergency response, meaning a 24-hour alert, daily damage reports, and the dispatching of experts and relief materials, said the statement.The ministry had sent teams to help with relief work in the provinces of Hebei, Shanxi, Jangsu, Anhui, Shandong, Henan, Shaanxi and Gansu, said the statement.The four-month drought had affected 35.1 percent of wheat crops, -- 96.11 million mu (6.4 million hectares) -- accounting for 21.7 percent of total farmland in the provinces, it said.The wheat growing area in the eight provinces accounted for more than 80 percent of the country's total, said the statement.The provinces have received little rainfall since October last year, it said.

UNITED NATIONS, Jan. 26 (Xinhua) -- China on Wednesday welcomed the smooth development of the south Sudan referendum, voicing its hope that the parties in south and north Sudan could reach a consensus at an early date on the outstanding issues through dialogue and consultations.Li Baodong, the Chinese permanent representative to the United Nations, made the statement in an interview with Xinhua after he spoke at the UN Security Council about the Chinese stance on the situation of Sudan.Earlier on Wednesday, the Security Council met to hear briefings from Atul Khare, UN assistant secretary-general for peacekeeping operations, and Ibrahim Gambari, the joint special representative of the African Union-United Nations Mission in Darfur (UNAMID), on the current situation in Sudan."China welcomes the smooth development of the south Sudan referendum, this is the result of the joint efforts of north and south Sudan and the international community," Li said."At present, priority should be given to the following work: First, continuous efforts should be made to fully maintain peace and stability in Sudan to enable the country to realize its long- term peace, stability and development," he said. "Second, efforts should be made to encourage the parties in south and north Sudan to continue their efforts for the full implementation of the Comprehensive Peace Agreement (CPA), particularly for a consensus at an early date on the outstanding issues."The referendum, with its week-long polling period ending on Jan. 15, will determine whether south Sudan remains a part of Sudan or becomes independent, in accordance with the 2005 CPA that ended a long-running north-south civil war.The referendum's preliminary results are expected to be announced by Feb. 2, and depending on whether appeals are launched in the courts, the final result will be declared on Feb. 7 or 14.

LOS ANGELES, April 7 (Xinhua) -- Using NASA's Galaxy Evolution Explorer (GEE) satellite, U.S. astronomers are hunting for nearby, hard-to-see stars which could very well be home to the easiest-to-see alien planets, it was announced on Thursday.U.S. astronomers are ferreting out the new targets after the glare of bright, shining stars has frustrated most efforts at visualizing distant worlds, NASA's Jet Propulsion Laboratory (JPL) said.So far, only a handful of distant planets, or exoplanets, have been directly imaged. Small, newborn stars are less blinding, making the planets easier to see, but the fact that these stars are dim means they are hard to find in the first place."Fortunately, the young stars emit more ultraviolet light than their older counterparts, which makes them conspicuous to the ultraviolet-detecting GEE," JPL said in a press release."We've discovered a new technique of using ultraviolet light to search for young, low-mass stars near the Earth," said David Rodriguez, a graduate student of astronomy at University of Californian, Los Angeles. "These young stars make excellent targets for future direct imaging of exoplanets."Young stars, like human children, tend to be a bit unruly -- they spout a greater proportion of energetic X-rays and ultraviolet light than more mature stars. In some cases, X-ray surveys can pick out these youngsters due to the "racket" they cause. However, many smaller, less "noisy" baby stars perfect for exoplanet imaging studies have gone undetected except in the most detailed X-ray surveys. To date, such surveys have covered only a small percentage of the sky, according to JPL in Pasadena, Los Angeles.Rodriguez and his team figured that the GEE, which has scanned about three-quarters of the sky in ultraviolet light, could fill this gap.Astronomers compared readings from the telescope with optical and infrared data to look for the telltale signature of rambunctious junior stars. Follow-up observations of 24 candidates identified in this manner determined that 17 of the stars showed clear signs of youth, validating the team's approach, JPL said."The Galaxy Evolution Explorer can readily select young, low- mass stars that are too faint to turn up in all-sky X-ray surveys, which makes the telescope an incredibly useful tool," Rodriguez said in the release.

WASHINGTON, April 6 (Xinhua) -- U.S. researchers have discovered two genes in which variation affects intake of caffeine, the most widely consumed stimulant in the world, according to a report described Wednesday in the open-access journal PLoS Genetics.A team of investigators from the National Cancer Institute, Harvard School of Public Health, Brigham and Women's Hospital, and the University of North Carolina at Chapel Hill examined genetic variation across the entire genome of more than 47,000 individuals from the U.S.They found the genes -- CYP1A2, which has previously been implicated in the metabolism of caffeine, and AHR, involved in the regulation of CYP1A2, played roles in regulating intake of caffeine. Individuals with the highest-consumption genotype for either gene consumed 40 mg more caffeine than those with the lowest-consumption genotype, equivalent to the amount of one-third cup of caffeinated coffee, or one can of cola.Caffeine is implicated in numerous physiological and medical conditions; it affects sleep patterns, energy levels, mood, and mental and physical performance. The identification of genes that have an impact on daily consumption offers opportunities to better understand these conditions. Further exploration of the identified genetic variants may provide insight into the speed of caffeine metabolism, how long caffeine circulates in the blood, or how strong the physiological effects of consuming a given amount of caffeine are.
