Loneliness is like a disease, and what's worse, it's contagious. It can spread from one person to another, according to the recent research that stresses the power of one person's emotions to affect even people he doesn't know.

    The new analysis, involving 4,793 people who were interviewed every two years between 2005 and 2015, showed that a friend of a lonely person was 52％ more likely to develop feelings of loneliness by the time of the next interview. A friend of that person was 25％ more likely, and a friend of a friend of a friend was 15％ more likely.

“Loneliness is not just the property of an individual. It can be transmitted across people—even people you don't have direct contact with,” said John T. Cacioppo, a psychologist of the University of Chicago who led the study published in the December issue of the Journal of Personality and Social Psychology.

    Loneliness has been linked to medical problems, including depression, sleep problems and generally poorer physical health. Identifying some of the causes could help reduce the emotion and improve health, experts said.

Although the study did not examine how loneliness spreads, Cacioppo said another research has provided clues. “Let's say for whatever reason you get lonely. You then interact with other people in a more negative fashion. That puts them in a negative mood and makes them more likely to interact with other people in a negative fashion and they minimize their social ties and become lonely,” Cacioppo said.

According to Cacioppo, loneliness spread more easily among women than men, perhaps because women were more likely to express emotions.

Lonely people become less and less trusting others. This makes it more and more difficult for them to make friends－and more likely that society will reject them. Therefore, it is important to recognize and deal with loneliness．Cacioppo emphasizes people who have been pushed to the edges of society should receive help to repair their social networks.

    Chiang Mai is proud of the city's 700- year history, which has rich traditional relics and unique culture. It is located 700 km north of Bangkok and is situated among the highest mountains in the country. Chiang Mai means “the new city” in Thai. King Mengrai founded the city as the capital of the Lanna Kingdom on April 12,1296. Therefore, Chiang Mai not only became the capital and cultural center of the Lanna Kingdom, but was also to be the center of Buddhism in northern Thailand. King Mengrai , a very religious leader, founded many of the city's temples (寺庙) that remain important today.

    It is one of the few places in Thailand where it is possible to experience both historical and modern Thai Culture. The city has old temples next to modern stores. It has more than three hundred temples, among which some are the most beautiful and honorable in the entire Buddhist world, giving the city an atmosphere (氛围) of calmness.

    The old city of Chiang Mai has various dialects, architecture, traditional values, festivals, handicraft and classical dances. In addition, it has hill tribes and their wealth of unique culture. Chiang Mai city features old-world beauty and charm as well as modern enjoyment and convenience. It is also filled with natural resources including mountains, waterfalls and rivers. Nowadays there are many activities and attractions both in the city and the surrounding province, including river rafting , elephant riding and golf.

    The quality of living is excellent. Accommodation and food are of the highest standard at a very low cost. Entertainment is plentiful with numerous festivals, outdoor activities and great nightlife. A number of elephant camps, numerous outdoor activities, a variety of handicraft workshops, various cultural performances, and breathtaking scenery make Chiang Mai one of Asia's most attractive tourist destinations.

    Do you know how it is when you see someone yawn and you start yawning too? Or how hard it is to be among people laughing and not laugh yourself? Well, apparently it's because we have mirror neurons (神经元）in our brains.

    Put simply, the existence of mirror neurons suggests that every time we see someone else do something, our brains imitate (模仿)it，whether or not we actually perform the same action. This explains a great deal about how we learn to smile, talk, walk, dance or play sports. But the idea goes further： mirror neurons not only appear to explain physical actions _y they also tell us that there is a biological basis for the way we understand other people.

    Mirror neurons can undoubtedly be found all over our brains, but especially in the areas which relate to our ability to use languages, and to understand how other people feel. Researchers have found that mirror neurons relate strongly to language. A group of researchers discovered that if they gave people sentences to listen to ( for example ："The hand took hold of the ball" ) , the same mirror neurons were triggered as when the action was actually performed (in this example, actually taking hold of a ball).

    Any problems with mirror neurons may well result in problems with behavior. Much researeh suggests that people with social and behavioral problems have mirror neurons which are not fully functioning. However, it is not yet known exactly how these discoveries might help find treatments for social disorders.

    Research into mirror neurons seems to provide us with ever more information concerning how humans behave and interact(互动）.Indeed, it may turn out to be the equivalent (相等物）for ncurosciencc of what Einstein's theory of relativity was for physics. And the next time you feel the urge to cough in the cinema when someone else does--well，perhaps you'll understand why.

    CHICAGO -- New research on vegetables and aging gives mothers another reason to say "I told you so." It is found that eating vegetables appears to help keep the brain young and may slow the mental decline（下降） sometimes associated with growing old.

    On measures of mental sharpness, older people who ate more than two servings of vegetables daily appeared about five years younger at the end of the six-year study than those who ate few or no vegetables.

    The research in almost 2,000 Chicago-area men and women doesn't prove that vegetables reduce mental decline, but it adds to mounting evidence pointing in that direction. The findings also echo（回应） previous research in women only.

    Green leafy vegetables including spinach（菠菜）, kale and collards （甘蓝） appeared to be the most beneficial. The researchers said that may be because they contain healthy amounts of vitamin E, an antioxidant（抗氧化剂） that is believed to help fight chemicals produced by the body that can damage cells.

    Vegetables generally contain more vitamin E than fruits, which were not linked with slowed mental decline in the study. Vegetables also are often eaten with healthy fats such as salad oils, which help the body absorb vitamin E and other antioxidants, said lead author Martha Clare Morris, a researcher at the Rush Institute for Healthy Aging at Chicago's Rush University Medical Center.

    The fats from healthy oils can help keep cholesterol（胆固醇）low and arteries （动脉）clear, which both contribute to brain health. The study was published in this week's issue of the journal Neurology and funded with grants from the National Institute on Aging.
