MOHE, Heilongjiang, Feb. 3 (Xinhua) -- Some 1.318 million tonnes of crude oil had flowed through an oil pipeline from Russia's far-east to China by Jan. 31, a month after the pipeline began operating, an officer of the Chinese operator of the pipeline said.The pipeline, which originates in the Russian town of Skovorodino in the far-eastern Amur region, enters China at Mohe and terminates at Daqing City of northeast China's Heilongjiang Province.The facility withstood the test of the severe coldness since it was put into operation on Jan. 1 and no production accident has been reported so far, said Gou Hanghai, director of the Mohe administration station of the pipeline.The pipeline remains a daily oil delivering capacity of 42,000 tonnes, he saidThe 1,000-km-long pipeline will transport 15 million tonnes of crude oil from Russia to China per year from 2011 to 2030, according to an agreement signed between the two countries.Some 72 kilometers of the pipeline is in Russia and 927 kilometers of it is in China.

LOS ANGELES, May 14 (Xinhua) -- Thousands of visitors, many of them children, went to the Jet Propulsion Laboratory (JPL) in Pasadena, California for the annual open house Saturday to experience the excitement in explorations.To many visitors, the open house is a rare opportunity to see the federally funded research and development center and the National Aeronautics and Space Administration (NASA) field center, which is close to the public. JPL is managed by California Institute of Technology.The event, themed "The Excitement in Explorations," provides visitors with the chance to share in the wonders of space through high-definition and 3-D videos, live demonstrations, interactions with scientists and engineers, and a first look at JPL's new Earth Science Center.The Earth Science Center showcases the home planet and JPL's Earth science missions. Since it was the first time open to the public, it attracted many visitors who had to wait for over an hour to get admitted.Visitors first passed by two touchscreens located on opposite walls of the facility that control real-time views of "Eyes on the Earth," an interactive 3-D visualization website. Visitors also had the opportunity to watch a movie in the 3-D theater, which seats up to 40 people.Other Open House highlights include: A chance to see the most unique car in this world before it leaves Earth: The next rover bound for Mars, Mars Science Laboratory/Curiosity, in the "clean room" before it is shipped to Florida for a November 2011 launch.JPL further runs its own "reality TV show" via live-streaming webcam: http://www.ustream.tv/nasajpl.The life-size rover models in a "Mars" test bed is another attraction and a perennial crowd-pleaser. Named the Robo-Dome, it is where visitors could see a pair of 700-pound robots gliding in a high-tech arena under artificial stars.The Robo-Dome is used to simulate complex maneuvers that could be used for future space missions.The year 2011 is an exciting year for JPL's robotic explorers. In the past twelve months, two spacecraft made close encounters of comets. This summer, the Dawn spacecraft will arrive at the giant asteroid Vesta.In 2011, JPL will launch the Aquarius satellite studying Earth' s ocean, the Juno mission to Jupiter, the Gravity Recovery and Interior Laboratory's twin spacecraft to Earth's moon, and JPL's next-generation rover - Mars Science Laboratory's Curiosity.

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.

PYONGYANG, Feb. 14 (Xinhua) -- Kim Yong Nam, president of the Presidium of the Supreme People's Assembly of the Democratic People's Republic of Korea (DPRK), met Chinese Minister of Public Security Meng Jianzhu here on Monday.Kim said it was the consistent stand of the Worker's Party of Korea (WPK) and the government and the firm will of the people to develop the traditional DPRK-China friendship generation after generation.The DPRK is sincerely happy to see the great achievement China has made and wish that the Chinese people make even more progress, Kim said.Meng, also a State Councilor, said the traditional friendship between the two neighboring countries has strengthened through the ages. He expressed his expectations of inheriting the friendship, deepening communications and cooperation in various areas and promoting the China-DPRK friendship.Ri Yong Ho, Presidium of Political Bureau of Central Committee of WPK and chief of the Korean People's Army General Staff, also met Meng on the same day.Ju Sang Song, a member of the Political Bureau of Central Committee of the WPK and Minister of People's Security, met Meng on Sunday. The two achieved consensus on making more efforts to develop cooperation and communications on public security to make active contributions to the traditional China-DPRK friendship. An agreement on cooperation between the the two security ministries was signed after the meeting.Meng arrived at Pyongyang on Sunday at the invitation of Ju Sang Song.
