It's long been thought that in order to succeed in life you need to think only of yourself and ignore the needs of others. New research,however,suggests the exact opposite is true and being nice to others actually makes you more likely to be successful. The scientists found that ‘givers' were more likely to share knowledge,and in turn gain more information themselves.

    Researchers divided participants into three groups based on a personality test: givers, takers and matchers. In a social dilemma task, participants were given a made-up donation which was equal to the amount of ￡ 240( $400). They were then asked to decide how much of their money they would give to a shared group pool. They were told that the money in the pool would be doubled and divided equally among all group members. Thus,it would be more beneficial to the group as a whole if everyone contributed their individual donations. However, it would be more beneficial for the individual if everyone else from the group contributed,while the individual kept his or her own money. The researchers used this strategic (策略的) information sharing task to examine how much and which pieces of information participants shared:the less important and already known information or the really important information only known by the individual.

    The results showed that givers are less self-centered and self-loving than takers. Givers shared not only more money with the group, but they also shared important information. Takers on the other hand kept both the money as well as different types of information.

    The findings suggest that it may not be enough to simply provide knowledge management tools in order to make the best of knowledge exchange in a group of people. It may be necessary for leaders and managers to keep in mind the personality styles of their employees. Specifically, they should be aware that takers may keep the important information for themselves.

    As any parent knows too well, sometimes a little white lie is the only way to make a naughty child quiet. Indeed, parents have shared the top white lies they've told their children. While some of them are amusing, others are somewhat cruel.

    “Father Christmas is watching you,” “Carrots will make you see in the dark” and “Your pet has gone to live on a farm” are among the top white lies parents tell their children. The top 20 list of little lies that adults use shows that four in five parents have told their children something that isn't true. The threat of Father Christmas is on the top, with 62 percent of parents employing St. Nick to keep their kids under control. The second on the list is: “We'll see”, which any little one knows really means “no”.

    The majority of British people say that they lie to their children to protect their innocence, to save them from being upset or to stop them behaving badly. The top white lie told to kids about their pets is “your pet has to live on a farm in the countryside”, which is employed after one dies or has gone missing. On average, parents think that children are ready to start learning about death at the age of seven and a half.

    One 62-year-old recalled that when he was four, his cat ran away, because it kept having its tail pulled. It was 53 years later that it was revealed that the cat had actually been given away to stop it from scratching the furniture. One respondent (应答者) said that he still remembered that when he was young, he believed his father's statement that the entire world used to be in black and white before colour photography came along.

    Forty percent of parents say that they would definitely lie to their children to keep up their belief in Father Christmas, and over all say they'd certainly tell the truth about a pet dying. However, one in ten parents say they've replaced their children's dead pet with a one looking the same to cheat their children into believing it was still alive and well, found the study by Blue Cross pet charity.

    Chris Thomas used to think of Facebook as just a platform to get in touch with his friends. He now believes the social networking service with saving his life. The 28－year－old was diagnosed with muscular dystrophy(肌肉萎缩症) nine years ago and has relied on a wheelchair ever since.

    On July 15，2015，Thomas was getting ready for bed in his apartment，when a shelving(架子) fell onto his wheelchair and knocked him over，causing him to fall and hit the back of his head. After waking up from a few minutes of coma(昏迷)，he realized he couldn't reach the string used to get the doorkeeper's attention.

    His phone was nearby and had the Facebook application conveniently open，so he posted a status update that immediately got his friends worried—even some he hadn't spoken to in years. “It was amazing，friends from six different states who didn't know each other were connecting with each other to get me help，” Thomas said. “Now that's the power of social media! You have hundreds of people at your fingertips.”

    Eight minutes after the status went up，an old friend，Leah，got in contact with Thomas' friend Brad，whose wife was in the neighborhood，and before you knew it there were 12 Facebook friends in his apartment，who took him to the hospital at once. They showed up to the rescue at the perfect time. Minutes before they arrived，Thomas thought he was going to have a panic attack，which he often suffers from because of his illness，but he's doing better now.

    “It felt good to know that my friends，even those I haven't spoken to in the past，came to save me，” Thomas said. “They all came together .I would've never imagined it.”

    The yearly Academy Awards ceremony was once a private affair. Now, because of television, it is very much a public affair. Hundreds of people gather in Hoolywood to see the Oscars presented to outstanding actors, and others involved（参与） in the motion picture industry. Millions more watch on the television.

    It all began on May 16, 1929, when 270 men and women sat down to dinner at the Hollywood Roosevelt Hotel. There was no secret about the winners. The names of the winners had been known for months. Janet Gaynor, for example had won as Best Actress. Douglas Fairbanks presented her with the famous gold statue（塑像）. The little statue was not then called Oscar. Like a new actor, Oscar was unknown. About six years later, it somehow got that renowned name. A number of explanations have been offered for its origin(由来), but nobody knows the true story for certain.

    Nowadays the result of the Oscar voting are kept secret. Only two people know the winners before the names are announced at the ceremony. The counting of votes is not done by one group of people but by different groups. Nobody except two members of an accounting company sees the final results.

    The information is not kept in open files. Winners' names are placed in closed envelopes. The accountants each carry a complete set of envelopes to the ceremony. One set is simply a spare to be used in case something happens to the other one.

    Researchers found that compared with young people who spent much of their free time in front of TV sets, those who were physically active often had higher self-respect, better grades and were less likely to have risky behavior like taking drugs, smoking, or drinking. The findings, based on a national survey of nearly 12, 000 middle and high school students, were published in a journal（期刊）.

    “Across the board, children who engaged in any kind of activity were better off than kids who watched a lot of TV,” said study co-author(合著者) professor Penny Gordon Larsen of the University of North Carolina.

    Other studies have linked certain content of television programs, such as violence and sex, to children's behavior. But beyond this issue, Gordon Larsen said that kids who spend hours watching TV” miss opportunities” to develop skills, learn teamwork and have other experiences that their more active peers(同辈) benefit(受益) from

    That doesn't mean, however, that kids have to be on the football team. The study found that some activities like skating and skateboard(滑板)——which adults sometimes frown upon——were also related to better self-respect and less risk-taking.

    That skaters were better behaved than TV-watchers might come as a surprise to some adults who consider these teens to be bad, according to Gordon Larsen. Skateboarding is forbidden in many public areas, and some communities(社区) disagree to build skating parks. But if kids who like to skate have nowhere to do it, “ it's a shame,” said Gordon Larsen.

    Not only should parents encourage their kids to engage（参与） in the physical activities they enjoy, she said, but schools and communities should also do more to create opportunities for children to be active.

    Is there a way to turn back the aging process in people? For centuries, people have been looking for a "fountain of youth." The idea is that if you find a magical fountain, and drink its water, you will not age.

    Researchers in New York did not find an actual fountain of youth, but they may have found a way to turn back the aging process. It appears that the answer may be called the hypothalamus, which is part of your brain. It controls important body activities, including growth, the way we process food and so on. Researchers found that hypothalamus neural stem cells (干细胞) also influence how fast aging takes place.

    Dongsheng Cai was the leading researcher in a study on aging in mice. He and his team reported their findings. "when the hypothalamus starts aging, particularly the loss of hypothalamus stem cells, so does the body." he said.

    Using this information, the researchers began trying to activate (激活) the hypothalamus in laboratory mice. The results show that the treatment slowed aging in the animals. "When we injected the hypothalamus stem cells to the middle-aged mice, the mice aged slowly and they could also live longer."

    But these results were just from studying mice in a laboratory. If the mice can live longer, does that mean people could have longer lives? The next step is to see if the anti-aging effects also work in human beings. If so, they say the findings could lead to new ways to help doctors identify and treat age-related health problems.
