Why do you go to the library? For books, yes—but you like books because they tell stories You hope to get lost in a story or be transported into someone else's life. At one type of library you can do just that—even though there's not a single book.

    At a Human Library, instead of books, you can "borrow" people. People with unique life stories volunteer to be the "books." For a certain amount of time, you can ask them questions and listen to their stories, which are as fascinating as any you can find in a book. (If you attend, make sure to review the habits that make you a good listener.) Many of the stories have to do with some kind of depressing topic. You can speak with a refugee, a soldier suffering from PTSD (创伤后遗症), a homeless person and a woman living with HIV. The Human Library encourages people to take time to truly get to know and learn from someone they might otherwise make a snap judgement about. According to its website, the Human Library is "a place where difficult questions are expected, appreciated and answered."

    The Human Library Organization came to be in Copenhagen, Denmark in 2000. Romni Abergel and his colleagues hosted a four-day event during a major Northern European festival. After the success of this event, Abergel founded the Human Library Organization, hoping to raise awareness among youth about depression, which has been growing ever since.

    Though there a few permanent human libraries, most aren't place at all, but events. Though many do take place at physical libraries, you don't need a library card—anyone can come and be part of the experience. There have been human library events all over the globe, in universities and in pubs, from Chicago to Tunis to Edinburgh to San Antonio. Check out the organization's Facebook page to see when the Human Library might be arriving near you.

    Getting paid to stay in bed all day sounds pretty good. But what if someone offered you $23,000 to stay in bed for two months? That's the deal that are search team is offering to 24 volunteers.

    Researchers are looking for volunteers to help them study the influences of weightlessness on the human body by spending 60 days lying down. Lying in bed isn't exactly the same as being weightless, but the influences on the human body are similar.

    When astronauts spend a long time in an environment with no gravity(重力), like the International Space Station (ISS),their bodies are affected in many ways. After a couple of months on the ISS, astronauts' hearts don't beat as hard. Their muscles（肌肉）become weaker because they no longer have to work against gravity. Their bones may break more easily. There may also be changes in the astronauts' sleep habits.

    Dr. Arnaud Beck, the researcher in charge of the study, said his goal is to measure the influences of weightlessness, and also to find ways to prevent problems. The study will take 88 days altogether. During the first two weeks the volunteers will be tested to establish(确定) their levels of fitness. Then they will spend 60 days lying in bed with their heads slightly lower than their bodies. They will have to do everything while lying down, including brushing their teeth and going to the bathroom. Dr. Beck said the rule is that they must have at least one shoulder touching the bed at all times. Half of the volunteers in the study will be taking capsules(胶囊) containing special food supplements（增补物）several times a day to see if they help reduce the health problems caused by weightlessness. The last two weeks of the study will be spent trying to let the volunteers recover. Volunteers must be men between the ages of 20 and 45 who are in perfect health. They must be non-smokers.

    The study will take place from September 1^st to November. The first two days are the time for volunteers to sign in.

    Sometimes you'll hear people say that you can't love others until you love yourself. Sometimes you'll hear people say that you can't expect someone else to love you until you love yourself. Either way, you've got to love yourself first and this can be tricky. Sure we all know that we're the apple of our parents' eyes, and that our Grandmas think we're great talents and our Uncle Roberts think that we will go to the Olympics, but sometimes it's a lot harder to think such nice thoughts about ourselves. If you find that believing in yourself is a challenge, it is time you build a positive self-image and learn to love yourself.

    Self-image is your own mind's picture of yourself. This image includes the way you look, the way you act, the way you talk and the way you think. Interestingly, our self-images are often quite different from the images others hold about us. Unfortunately, most of these images are more negative than they should be. Thus changing the way you think about yourself is the key to changing your self-image and your whole world.

    The best way to defeat a passive self-image is to step back and decide to stress your successes. That is, make a list if you need to, but write down all of the great things you do every day. Don't allow doubts to occur in it.

    It very well might be that you are experiencing a negative self-image because you can't move past one flaw or weakness that you see about yourself. Well, roll up your sleeves and make a change of it as your primary task. If you think you're silly because you aren't good at math, find a tutor. If you think you're weak because you can't run a mile, get to the track and practice. If you think you're dull because you don't wear the latest trends, buy a few new clothes. But remember, just because you think it doesn't mean it's true.

    The best way to get rid of a negative self-image is to realize that your image is far from objective, and to actively convince yourself of your positive qualities. Changing the way you think and working on those you need to improve will go a long way towards promoting a positive self-image. When you can pat yourself on the back, you'll know you're well on your way. Good luck!

    Healthy, convenient and increasingly popular over the past few years, sushi has become as common a dish in the UK as in India or China. It's a popular lunch-choice for city-workers all over the country and you're never far from a restaurant or supermarket selling the traditional Japanese dish. But it turns out sushi may not be as healthy a choice as we thought — leading biologists have warned that it is in fact harming both the environment and our health.

    The UK sushi market is worth £69 million a year, but because we're eating so much of it, the tuna (金枪鱼) population in the oceans is dwindling. According to Professor Daniel Pauly and Dr Dirk Zeller, the leaders of British Columbia, Bluefin and yellowfin tuna populations have reached dangerous levels.

    Bluefin tuna is often served in high-end, excellent sushi restaurants, while yellowfin is more common in high-street sushi bars and supermarkets. Increasing global need means tuna populations are being overfished. Most of the UK's sushi comes from the Indian Ocean, but according to Professor Pauly we now only have 2-3 percent of what we had 200 years ago.

    Professor Pauly and Dr Zeller believe it is our love of healthy tuna that's causing the problems in our oceans. The fish is popular not just for its taste but for its health benefits. But while sushi has earned popularity for being low in calories and high in nutrients (营养物), we may have overestimated (高估) its health value.

    In advance of a lecture at the Zoological Society of London lately, Professor Pauly said he believes most high-street restaurants serve sushi that contains plastic microbeads (塑料微珠). “Microbeads are poison pills which take in all the pollutants and they are eaten by little fish which are then eaten by tuna.”

    So what should we eat instead? Dr Zeller and Professor Pauly are asking the public to step away from sushi and eat more fish like anchovies (凤尾鱼) — less attractive, but better for your health and the environment.

    A 27-year-old inventor, Joco Paulo Lammoglia, has come up with a new device named the AIRE mask, which is capable of converting the wind energy provided by the wearer's breath into electrical energy. This means breathing has become a source of renewable energy. The inspiration for the invention came from his watching children blowing on pinwheels (纸风车).

    The device is worn like a mask equipped with tiny wind turbines (涡轮) and it can work its magic even while people are sleeping, jogging or hanging around, since energy is created from one's breath. The principle of this AIRE mask is simple. The invention uses the wind flow created by breathing and changes it into energy that can charge mobile phones and iPods. Simply put this mask connected to your mobile phone on your face. The rest takes place naturally through your breath that provides power to run turbines which produce electricity.

    Lammoglia explained how useful he hopes the AIRE will become. He said, "I hope to bring the concept into production and reduce the carbon footprint. It can be used indoors or outdoors, while you're sleeping, walking, running or even reading books." Apart from saving energy and contributing to environmental protection, it also encourages the practice of physical exercise. This is an entirely all time renewable energy source. Its energy is available 24 hours a day, seven days a week.

    Lammoglia explained why he thought the AIRE was so useful, saying, "Though many of our modern devices offer benefits, they tend to consume a high amount of electrical energy. This may cause problems for the environment, especially if the energy used by these devices is obtained from non-renewable sources.

    The AIRE mask will be future's cheaper source of charging mobile phones. It would save energy and allow people to never have to worry about their phone dying unless they stop breathing.

    A Christmas Carol was written by Charles Dickens. The first 6,000 copies of the book were sold out in a week. And the book has inspired many plays and movies. The first play was put on in 1844. The first two movies were silent films made in 1901 and 1908. Since then, the story has been remade more than 60 times for television and cinema. What makes such a tale so attractive? Audiences have always loved a good plot, a villain(反面人物) who harms other people or breaks the law, and the ending of right over wrong. The book offers all three.

    The book tells the story of a man named Ebenezer Scrooge. He is mean and cruel(残忍的) to his clerk and turns away his only living relative. One night, Scrooge is visited by three spirits. The first shows scenes from Scrooge's youth that led to this present state. The second takes him to the homes of his clerk and his nephew. Here Scrooge sees that people can be happy without lots of money. The spirit also shows him the desperate poor people of London. The third spirit shows Scrooge will die alone, and no one will care if he continues to live as he has. At last the message is understood, and Scrooge repents. He becomes generous and caring to all around him, especially to his clerk's sick son, Tiny Tim.

    Every year, thousands of people watch A Christmas Carol. Why? They may be touched by its lessons on the true meanings of wealth and happiness. They may enjoy the special effects and feelings or watching every year may be just a habit. Viewers never seem to grow tired of the old miser(守财奴), Scrooge, and his dramatic message of hope and change.
