    Advice to "sleep on it" could be well founded, scientists say. After a good night's sleep a problem that couldn't be solved the night before can often appear more manageable, although the evidence until now has been anecdotal. But researchers at the University of Luebek in Germany have designed an experiment that shows a good night's sleep can improve insight and problem-solving.

    "If you have some newly-got memories in your brain, sleep acts on these memories and restructures them, so that after sleep the insight into problem which you could not solve before increases," said Dr. Jan Born, a neuroscientist, at the university. To test the theory, they taught volunteers two simple rules to help them turn a string of numbers into a new order. There was also a third, hidden rule, which could help them increase their speed in solving the problem. The researchers divided the volunteers into two groups: half were allowed to sleep after the training while the rest were forced to stay awake.

    Dr. Jan Born and his team noticed that the group that had slept after the training were twice as likely to figure out the third rule as the other group. "Sleep helped," Born said in a telephone interview. "The important thing is that you have to have a memory representation in your brain of the problem you want to solve and then you sleep, so it can act on the problem.

    "But Born admitted that he and his team don't know how restructuring of memories occurs or what governs it. Pierre Maquet and Perrine Ruby of the University of Liege in Belgium said the experimental evidence supports the anecdotal suggestions that sleep can help develop creative thinking. Although the role of sleep in human creativity will still be a mystery, the research gives people good reason to fully respect their periods of sleep, they added.

    La Tomatina, Spain

    Tomato juice flows through the streets of Bunol on the last Wednesday of August as the worlds largest tomato fight happens. Festivities begin in the town square where there is a huge pole covered in soap and with a leg of ham at the top. Participants try to climb up the pole to get the ham as watchers throw buckets of water to them. After a gun is fired to signal the beginning of the fight, people catch the tomatoes and throw each other in the streets until the gun sounds again, marking the end of the event.

    Holi, India

    This spring festival is celebrated throughout the country in late February or early March. The two-day event celebrates the legend of Prahlad, who escaped unharmed from the fire of the evil Holika Dahan. People mark the event by lighting fires and throwing colored powder on one another Children load colored water into toy pistols called pichkari and take aim at passers-by. Holi is known as a happy celebration of the victory of good over evil.

    Burning Man, Nevada

    This infamous festival began in 1986 with the burning of a large figure to mark the summer solstice (夏至). It's since grown into a week-long annual event that draws more than 48,000 people to the Black Rock Dessert. It is held during the week before Labor Day. Participants set up camp in the desert to celebrate art.

    Songkran, Thailand

    This festival marks the Thai New Year, which is celebrated in the second week of April. This is the hottest time of the year in Thailand, so it makes sense that the biggest Songkran tradition is to throw water on people. Thais of all ages join in water fights, using buckets, hoses (软管) and water guns to celebrate the event.

    So many of us hold on to little resentments that may have stemmed from an argument, a misunderstanding, or some other painful event. Stubbornly, we wait for someone else to reach out to us―believing this is the only way we can forgive or rekindle(重新点燃) a friendship or family relationship.

    An acquaintance of mine whose health isn't very good, recently told me that she hasn't spoken to her son in almost three years. "Why not" I asked. She said that she and her son had had a disagreement about his wife and that she wouldn't speak to him again unless he called first. When I suggested that she be the one to reach out, she resisted initially and said, "I can't do that. He's the one who should apologize." She was literally(简直) willing to die before reaching out to her only son. After a little gentle encouragement, however, she did decide to be the first one to reach out. To her amazement, her son was grateful for her willingness to call and sincerely said sorry to her. As is usually the case when someone takes the chance and reaches out, everyone wins.

    Whenever we hold on to our anger we turn "small thing" into "big thing" in our minds. We start to believe that our positions are more important than our happiness. They are not. If you want to be a more peaceful person you must understand that being right is to let go, and reach out. Let other people be right. This doesn't mean that you're wrong. Everything will be fine. You'll experience the peace of letting go as well as the joy of letting others be right. You'll also notice that as you reach out and let others be "right" they will become less defensive and more loving toward you. They might even reach back. But if for some reason they don't that's okay too. You will have the inner satisfaction of knowing that you have done your part to create a more loving world and certainly you'll be more peaceful yourself.

    Research finds out why some people are constantly under attack from the bloodsucking insects while others walk free.

    For those unfortunate enough to feature highly on the mosquito hit list, summer nights can be synonymous with mosquito bites. Yet others hardly ever get bitten. So how do the bloodthirsty insects select their victims?

    The insects' tastes may seem arbitrary. However, research shows that when mosquitoes make their choices between potential victims, it all comes down to scent (气味).

    “Mosquitoes are attracted by carbon dioxide and heat, which everyone gives off. But mosquitoes are also attracted by certain scents,” says Karl-Martin Vagn Jensen, the head of research at the Department of Agricultural Science at Arhus University.

    According to Jensen, it has not yet been confirmed exactly what the scents in question are. But research does indicate that some scents are more attractive to mosquitoes than others.

    “All the lab employees rubbed petri dishes (培养皿) against their stomachs. In that way, their scents were put on the dishes, which were then put in a container full of mosquitoes,” he says. “The mosquitoes repeatedly landed on some of the petri dishes, but didn't go anywhere near the others.”

    Perhaps taking inspiration from popular fiction, there are also those who consider garlic as an excellent repellent (驱虫剂) against the winged bloodsuckers. According to the researcher, this strategy may not be entirely fruitless. “As far as I know, there is no scientific proof that eating garlic works. But there may be something to the theory that it's possible to mask scent with garlic,” he says. The only reliable method of protection against mosquitoes is to use repellents that are sold over the counter. It contains some smells that can confuse the mosquitoes. When the mosquito comes closer, it uses smell, heat and carbon dioxide to decide whether to bite. But if it is confused by a repellent, it will never get that far.

    Dolphins, African gray parrots and some other animals understand the idea of “zero,” but researchers were surprised to find that honeybees also comprehend this abstract concept, considering the insects' tiny brains, according to a new study. Honeybees have fewer than one million neurons (神经元), compared with the 86 billion neurons in humans—and yet, they grasp a concept that humans, by some measures, don't start to understand before preschool.

    The researchers set up two cards, each of which had a set of symbols on them, like triangles or circles. Then, they trained a group of the bees to fly to the card with the lower number of symbols. The bees quickly learned what the humans wanted them to do to get their delicious, sweet rewards. The trained bees were then shown a card that was empty and one that had symbols on it. There is no need for the bees to be trained to fly more often to the empty card—thus showing that they understood that “zero” was a number less than the others.

    Although they flew more often to an empty card than to one that had one symbol on it, it became easier for them to distinguish when the symbols on the card increased in number. For example, they more often flew to the zero when the other card had four symbols than when it had one.

    Perhaps these findings will explain the brain mechanism (机制) behind what allows us to understand the concept of “nothing,” Adrian Dyer, a researcher said. This understanding, in turn, could help in the development of artificial intelligence (AI) that also understands this concept. “If bees can understand 'zero' with a brain of less than a million neurons, it suggests there are simple, efficient ways to teach AI new tricks,” Dyer said in the statement.

    Twenty years ago, most experts believed that differences in how boys and girls behaved were mainly due to differences in how they were treated by their parents, teachers, and friends. It's hard to cling to that belief today. Recent research has shown that there are biological differences between boys and girls. Understanding these differences is important in raising and educating children.

    For example, girls are born with more sensitive hearing than boys, and the difference increases as kids grow up. So when a grown man speaks to a girl in what he thinks is a normal voice, she may hear it as yelling. Conversely (反过来), boys who appear to be inattentive in class may just be sitting too far away too hear the teacher.

    Likewise, girls are better in their expression of feelings. Studies reveal that negative emotions are seated in an area of the brain called the amygdala. Girls develop all early connection between this area and the cerebral cortex (大脑皮层), enabling them to talk about their feelings. In boys these links develop later. So if you ask a troubled adolescent boy to tell you what his feelings are, he often cannot say much.

    Dr. Sax, an advocate of single-sex education, points out that keeping boys and girls separate in the classroom has yielded striking educational, social, and interpersonal benefits. Therefore, parents and teachers should try to recognize, understand, and make use of the biological differences that make a girl a girl, and a boy a boy.
