The hottest“green”toy in Germany isn't made of organic or recycled materials.This one has a solar panel and only runs if kids remember to insert bright red “energy stones”that power the space station.Germany，a pioneer in many renewable energy initiatives，is also at the forefront of creating environment­friendly toys aimed at making kids think about where energy comes from and how much of it they can use，raising awareness through play.A number of high­tech green toys are on display at this year's Nuremberg toy fair，which runs through Sunday.

    Among them，there are hydroelectric­powered(水电动力的)toy cars，and doll houses with wind turbines and rainwater catchers.The bright green “Future Planet”space station features an inner atrium(中庭)with a fan that is powered by a functioning solar cell.Its aim is to get kids to use their imagination about how energy will be created in the future.

    Makers and retailers believe such toys will play an increasingly important role in their future—and that of our kids.“Energy is the question of the future and we are definitely thinking about this as we move ahead，”said Judith Schweinitz，a spokeswoman for Playmobil，maker of the solar panel­fitted space station.“It is increasingly being brought into our play concept.”Green toys—which range from those made of sustainable materials to ones like the space station that just raise environmental awareness—make up only a sliver of the $ 84 billion international toy market，but their share is growing，studies indicate.Environmental research firm Earthsense，based in Syracuse，New York，predicts that green toys will account for about $ 1 billion，or 5 percent of U．S.toy sales in the next five years.Parents are smart and they want information about what's in the product.That's what's really driving the market.

    For anyone still doubting the belief that our emotions influence our physical health, a new study from New Zealand should be able to settle the matter. It reports that the physical wounds of healthy seniors healed more quickly if they wrote about their most upsetting experiences.

    This confirms the results of a 2010 study, and extends those findings to cover older adults—a group that is likely to suffer wounds (as from surgery), and one with less access to other ways of lowering tension (such as exercise).

    Reported in the journal Psychosomatic Medicine, a research team led by the University of Auckland's Elizabeth Broadbent made a study featuring 50 healthy adults ranging in age from 64 to 97. They were asked to write for 20 minutes per day for three consecutive (连续的) days.

    Half were asked to write about the most upsetting experience in their life, describing their deepest thoughts, feelings, and emotions about the events, ideally not previously shared with others. The others were asked to write about their daily activities without mentioning emotions, opinions or beliefs.

    Two weeks after the third day of writing, all participants received a standard 4mm skin biopsy (皮下活体组织检查) on their inner arm. The very tiny wounds caused by the biopsy were photographed regularly over the following days to determine the rate at which they healed.

    On the 11th day after the biopsy, the wounds completely healed on 76.2 percent of those who had done the expressive writing. That was true of only 42.1 percent of those who had written about everyday activities.

    “The biological and psychological mechanisms (机体) behind this effect remain unclear,” the researchers wrote, noting that those who had done the expressive writing did not report lower stress levels or fewer depressive symptoms than the others in the control group. Even if they weren't consciously aware of feeling more relaxed or positive, the expressive writing appeared to have caused some sort of bodily reaction—probably involving their immune systems—that hastened their recovery.

    We humans spend about one-third of our lives asleep. This may sound like a lot of time, but it is not wasted. Sleep not only helps us stay healthy but it also helps our brains remember. Our brains need good sleep to remember what we do and learn during the other two thirds of our lives when we are awake.

    Researchers at the University of Wisconsin-Madison have found that sleep helps improve brain performance by shrinking(收缩)synapses in the brain. A synapse is the area where cells pass messages to other cells.

    Scientist Chiara Cirelli is a leader at the school's Center for Sleep and Consciousness. She told the reporter that sleep is when the human brain mixes information it has learned while awake into its general collection of knowledge. Meanwhile, the brain forgets unimportant details. This forgetting is important. It makes space for new learning and new memories.

    Cirelli said that the Centers research began with this hypothesis(假设): We sleep so that our brain can repair and refresh itself. She said the idea seems simple and reasonable. However, testing and discovering how it works has been extremely difficult.

    Synapses are only about 20-40 nanometers(纳米)wide. The team began their study by measuring the size of the synapses to look for changes in these already tiny spaces between nerve cells. Cirelli says the process(过程) is difficult because"all the actual measurements of the synapses have to be done by hand." The team had to wait until improvements in laboratory technology made it possible to see these tiny changes. A University of Wisconsin press release called the research a"huge job." Many research specialists worked for four years to photograph, rebuild and study certain areas of a mouse brain. The report also said the scientists measured 6,920 synapses.

    Cirelli says they found that our synapses shrink as our brains clean themselves during sleep. We wake up refreshed and ready to fill those synapses with new information. The research findings are the result of years of hard work at the University of Wisconsin Madison. The researchers published their findings in the journal Science.

    Why do people lie? Many psychologists agree that it can start from childhood? There are various reasons why children make false statements. They usually tell untruthful stories to cover up the mistakes that they have done in the past. Lying is also a way to avoid receiving punishments from parents. If parents fail to reprimand their children for making up false stories, then there is a possibility that they will continue to lie during their teenage years.

    Teenagers lie because they want to be accepted by their friends. This is the main reason why they create stories that are not true just to become presentable and acceptable to other people. In some instances, teenagers tell untruthful statements to avoid criticisms from their families and friends.

    As teenagers grow, lying becomes one of your habits. Their knowledge on making up untruthful stories becomes more developed. People lie in workplaces if they fail to meet the deadlines and if they fail to accomplish and do their tasks efficiently. Some of the common lies made in workplaces are getting sick and having emergencies at home. The danger involved in frequent lying is when it, becomes a character. Frequent lying causes the development of the condition known to doctors as pathological（病态的）lying.

    Pathological lying is a mental health condition, which is associated with individuals who have the urge to tell untruthful statements. Patients suffering from it make up stories about everything and anything. These individuals lie to meet the standards of other people who they want to please. These patients deceive other people because it gives them an unexplained pleasure. One of the best ways of treating pathological liar is to help them tell true statements and stories at all times. This may be hard for them, but as they are accustomed to it, they will start to realize that they will be more accepted by their families and other people if they stop themselves from making up for stories

    Positive thinking is a significant element of happiness. In order to become a positive thinker, determination and consistency are important. The first thing to know about positive thinking is that everyone can do it.  With certain cognitive (认知的) and behavioral changes, we can all become positive thinkers. Another important factor is that being a positive thinker does not mean you become numb to anything that is not working properly in your life or is negative - it just means that you approach life and face challenges with a healthier outlook.

    Instead of selectively attending to negative events, focus on the positive ones. Then pay attention to the delayed consequences of your behavior rather than the immediate ones. For example, if a job is not going like you want, focus on the fact that you have a job and how you can take your time to make the situation better.

    Challenge any internal attributions and see if you compare your behavior to standards that are excessively rigid and perfectionistic. If so, change these and be reasonable with your comparisons. For example, if you constantly compare your weaknesses with other people's strengths, then switch this and compare yourself with those who are doing poorer than you as well. Overall, people who focus more on their strengths than their weaknesses but at the same time are aware of their weaknesses have a healthier self-evaluation result.

    When faced with too much fear about a situation, imagine the worst case and visualize a solution for it, then let go of fear. This way, you will be prepared for anything and your fear will not block you from being open and creative to different solutions. For example, if you are constantly worried about losing your job up to a point where it is creating a lot of anxiety and fear and is effecting your performance and your happiness negatively, then think of losing your job, visualize how you will handle it, find solutions in your mind and then let go of the thought and the fear attached to it.

    So positive thinkers are better problem solvers and have better interactions. In addition to that, people who are positive thinkers are happier and more satisfied with their life.
