BEIJING, March 29 (Xinhuanet) -- A new study has found that rejection can literally hurt in the same way as physical pain does, according to media reports Tuesday.Researchers found that intense emotional pain, such as feelings of rejection after a breakup of a relationship, can trigger brain activities similar to when people suffer physical pain.The research findings were published in Tuesday's Proceedings of the National Academy of Sciences.The study followed 40 volunteers who experienced unwanted romantic breakups in the past six months, and the researchers analyzed their brain activity during two "painful" situations.The results showed that the two situations, thinking about the loss of their ex-partner and experiencing mild physical pain similar to holding a very hot coffee cup, caused response in the overlapping parts of the brain."This tells us how serious rejection can be sometimes," said study author Edward E. Smith, director of cognitive neuroscience at Columbia University. Smith added. "Our ultimate goal is to see what kind of therapeutic approach might be useful in relieving the pain of rejection."

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, May 14 (Xinhua) -- The uranium subsidiary of China Guangdong Nuclear Power Group (CGNPG) has said it is developing two large mines in the mainland.The two mines will be located in south China's Guangdong province and northwest China's Xinjiang Uygur Autonomous Region, according to Saturday's China Daily.The move is likely to add as much as 1,000 tonnes to the country's annual production capacity of the nuclear fuel."The two mines are expected to start operation in 2013, each with an annual production capacity of no more than 500 tonnes," the newspaper quoted Zhou Zhenxing, chairman of CGNPG Uranium Resources Co (CGNPG-URC) as saying.

LOS ANGELES, May 9 (Xinhua) -- Drinking alcohol may raise the likelihood among teenagers to spend more time on computers, a new study suggests.The study, conducted by researchers at Weill Cornell Medical College, was based on a survey of 264 teenagers, aged 13 to 17.Results showed that compared with teens who did not report drinking, those who drank alcohol in the last month used a computer more hours per week for non-school-related activities, including the use of social networking sites.Drinking was also linked to more frequent social networking and listening to and downloading music, according to the study published Monday in the on-line edition of the journal Addictive Behaviors.However, there was no demonstrated link between alcohol use and computer use for school work, neither there was strong link between video games and drinking or on-line shopping and drinking."While the specific factors linking teenage drinking and computer use are not yet established, it seems likely that adolescents are experimenting with drinking and activities on the Internet," said Dr. Epstein, assistant professor of public health at the college."In turn, exposure to on-line material such as alcohol advertising or alcohol-using peers on social networking sites could reinforce teens' drinking."Children are being exposed to computers and the Internet at younger ages. For this reason it's important that parents are actively involved in monitoring their children's computer usage, as well as alcohol use."Teenagers typically first experiment with alcohol at age 12 or 13, according to the study.Family risk factors include lax parental supervision and poor communication, family conflicts, inconsistent or harsh discipline and a family history of alcohol or drug abuse."According to a national study conducted by the Pew Internet and American Life Project, more than half of parents of teenagers had filters installed on the computers their child uses to block content parents find objectionable, yet many parents do not use any form of parental monitoring, particularly for older teens," Epstein said.

NICOSIA, March 8 (Xinhua) -- Cypriot geneticists have reported a non-invasive Down's Syndrome test that could possibly replace the risky amniocentesis procedure now in use.A team of researchers at the Cyprus Institute of Neurology and Genetics reported in Nature Medicine journal that the new test involves only a small quantity of blood taken from the mother's arm, which is analyzed to detect DNA differences between the mother and the fetus.Philippos Patsalis, medical director of the institute, said Tuesday the new method eliminates dangers involved with amniocentesis testing, which involves sampling amniotic fluid by inserting a hollow needle into the mother's uterus.At present, only women belonging to high risk groups, including older women, are tested for Down's Syndrome, which is the most common genetic cause of mental retardation.Patsalis, who led the study, said the new method would be made available to the medical community after clinical tests are concluded world-wide on 1,000 women within two years.
