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, March 19 (Xinhua) -- Radiation leaks following explosions at the Fukushima Daiichi nuclear power plant in Japan will not affect China's environment and the health of its citizens during the next three days, authorities said Saturday.China's National Nuclear Emergency Coordination Committee made the announcement based upon analyses of environmental monitoring, meteorological forecasts, and ocean currents.The Beijing-based Regional Specialized Meteorological Center, which is affiliated with the World Meteorological Organization, issued its forecast on Saturday afternoon, saying that the radioactive leakages in Japan would not affect China over the next three days.The country's State Oceanic Administration on Saturday announced that no abnormalities were detected in terms of atmospheric radiation over the East China Sea, the northern part of the South China Sea, and the central and northern regions of the Yellow Sea.The administration predicts that the ocean currents near Fukushima would mainly travel eastward from Japan over the next three days.Furthermore, the country's Ministry of Environmental Protection announced that China's environment remains normal based upon the monitoring of radiation levels.

BEIJING, Feb. 2 (Xinhua) -- Two more planes flew 435 more Chinese back home from Egypt Wednesday afternoon.An airliner with 213 Chinese from Cairo landed at the Beijing Capital International Airport at 2:19 p.m., and another with 222 Chinese including many Hong Kong people from Luxor landed at a Hong Kong airport at 3:25 p.m..These flights were another strive of the Chinese government and airline operators to get stranded Chinese nationals out of Egypt, where anti-government demonstrations have led to chaos in several major cities including Cairo.So far, 1371 stranded Chinese had been taken home by six flights.

WASHINGTON, May 20 (Xinhua) -- Two U.S. astronauts conducted the first of four spacewalks for space shuttle Endeavour's STS-134 mission on Friday morning, the U.S. National Aeronautics and Space Administration (NASA) said.According to the U.S. space agency, Endeavour's mission specialists Andrew Feustel and Greg Chamitoff completed the six-hour, 19-minute spacewalk at 9:29 a.m. EDT (1329 GMT). They successfully installed antennas for the External Wireless Communication system, routing cables, setting up the antenna, installing handrails, and connecting power cables.Because of a carbon dioxide sensor failure in Chamitoff's spacesuit, flight controllers limited his spacewalk time to about six hours 20 minutes, 10 minutes less than the planned six hours and 30 minutes. There was no indication his suit's carbon dioxide levels would rise. However, they deferred tasks to remove a micrometeoroid debris shield to access and attach some of the connection points.This was the 245th spacewalk conducted by U.S. astronauts. It was Feustel's fourth spacewalk for a total time of 27 hours and 17 minutes, and Chamitoff's first.Endeavour lifted off on Monday morning from Kennedy Space Center in Florida, to deliver to the International Space Station a 2-billion-dollar, multinational particle detector known as the Alpha Magnetic Spectrometer (AMS).AMS, a particle physics detector, is designed to search for various types of unusual matter by measuring cosmic rays. Its experiments are designed to help researchers study the formation of the universe and search for evidence of dark matter, strange matter and antimatter.

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.
