Exercise may help to safeguard the mind against depression through previously unknown effects on working muscles, according to a new study involving mice.

    Mental health experts have long been aware that even mild, repeated stress can contribute to the development of depression and other mood disorders in animals and people. Scientists have also known that exercise seems to cushion against depression. But precisely how exercise, a physical activity can lessen someone's risk for depression, a mood state, has been mysterious. So for the new study, researchers at the Karolinska Institute in Stockholm studied the brains and behavior of mice in a complicated and novel fashion.

    We can't ask mice if they are feeling cheerful or in low spirits. Instead, researchers have pictured certain behaviors that indicate depression in mice. If animals lose weight, stop seeking out a sugar solution when it's available — because, probably, they no longer experience normal pleasures — or give up trying to escape from the cold-water zone just freeze in place, they are categorized as depressed. And in the new experiment, after five weeks of frequent but low-level stress, such as being lightly shocked, mice displayed exactly those behaviors. They became depressed.

    The scientists could then have tested whether exercise blunts (延缓) the risk of developing depression after stress by having mice run first. But, frankly, from earlier research, they wanted to know how, so they bred pre-exercised mice. A wealth of earlier research by these scientists and others had shown that aerobic exercise, in both mice and people, increases the production within muscles of an enzyme (酶) called PGC-1alpha. The Karolinska scientists suspected that this enzyme somehow creates conditions within the body that protect the brain against depression. Then, the scientists exposed the animals, which without exercising, were in high levels of PGC-1alpha to five weeks of mild stress. The mice responded with slight symptoms of worry. But they did not develop depression. They continued to seek out sugar and fought to get out of the cold-water zone. Their high levels of PGC-1alpha appeared to make them depression-resistant. Finally, to ensure that these findings are relevant to people, the researchers had a group of adult volunteers complete three weeks of frequent endurance training, consisting of 40 to 50 minutes of moderate cycling or jogging. The scientists conducted muscle biopsies (活体检查) before and after the program and found that by the end of the three weeks, the volunteers' muscle cells contained substantially more PGC-1alpha than at the study's start. The finding of these results, in the simplest terms, is that “you reduce the risk of getting depression when you exercise,” said Maria Lindskog, a researcher at the Karolinska Institute.

    For the past four days, the streets of India have been brightly lit and full of festivities. Millions of people around the country have been celebrating the festival of Diwali.

    Diwali has been celebrated in India for hundreds of years. It takes place each year in either October or November. Although the holiday lasts only one night, people continue to celebrate for several days.

    People light oil lamps during the festival. In the tradition of the Hindu religion, the lamps are meant to celebrate the victory of light over darkness and good over evil (邪恶). The holiday also celebrates the start of a new year in the Hindu calendar. But Diwali is an important festival in many other Indian religions as well, including Sikhism and Jainism. In a country of more than 1.2 billion people and different religious beliefs, Diwali is a celebration that touches everyone.

    Diwali means “rows of lamps” in Sanskrit, a language used in many Indian religions. During the festival, families and friends come together to light the oil lamps，which are called diyas. Then they put the lamps in rows outside their homes and temples.

    As in other cultures' winter holidays，sweets and gifts are also a big part of Diwali. Neighbors and friends share treats, called mithai, and exchange presents.

    Employers often use the holiday to express appreciation for their workers. This year, a businessman even bought cars and houses for some of his employees!

    The Diwali spirit can be felt outside India as well. Indians in countries around the world, including the U. S. and Canada，are also celebrating the holiday this week.

    A girl had to usually face adversity(逆境). One day, she couldn't help complaining to her father about her life and how things were so hard for her. She didn't know how she was going to make it and wanted to give up. She was tired of struggling. It seemed as one problem was solved a new one arose.

    Her father, a chef, took her to the kitchen. He filled three pots with water and placed each on a high fire. Soon the pots came to a boil. In one he placed carrots, in the second he placed eggs, and in the last he placed ground coffee beans. He let them into the water and boil, without saying a word.

    The daughter waited impatiently, wondering what he was doing. In about twenty minutes he turned off the burners. He made the carrots out and placed them in a bowl. He pulled the eggs out and placed them in another bowl. Then he poured the coffee out and placed it in a cup. Turning to her, he asked, "What do you see?" "Carrots, eggs and coffee," she replied.

    He brought her closer and asked her to feel the carrots. She did and noted that they were soft. He then asked her to take an egg and break it. After pulling off the shell, she observed the hard-boiled egg. Finally, he asked her to sip the coffee. She smiled, as she tasted its rich aroma(香味). She humbly asked, "What does it mean, Father?"

    He explained that each of them had faced the same hardship, boiling water, but each reacted differently. The carrot had been strong and hard. But after being subjected to the boiling water, it softened and became weak. The egg had been easily broken. Its thin outer shell had protected its liquid interior. But after going through the boiling water, its inside became hardened. The ground coffee beans were unique. After they were in the boiling water, they changed the water. "Which are you?" he asked his daughter. "When adversity knocks on your door, how do you respond? Are you a carrot, an egg, or a coffee bean?"

    How about you, my friend? Are you the carrot that seems hard, but with pain and adversity you move back and become soft and lose your strength? Are you the egg, which starts off with a flexible heart? Were you a liquid spirit, but after a breakup, a divorce, or a layoff have you become hardened and stiff? Your shell looks the same, but are you bitter and tough with a stiff heart? Or are you like the coffee bean? The bean changes the hot water, the thing that is bringing the pain. When the water gets the hottest, it just tastes better. If you are like the bean, when things are at their worst, you get better and make things better around you.

    Ask yourself how you handle adversity. Are you a carrot, an egg, or a coffee bean?

    If Confucius (孔子) were still alive today and could celebrate his September 28 birthday with a big cake, there would be a lot of candles. We'd need a fan or a strong wind to help him put them out. While many people in China will remember Confucius on his special day, few people in the United States will give him a passing thought. It's nothing personal. Most Americans don't even remember the birthdays of their own national heroes.

    But this doesn't mean that Americans don't care about Confucius. In many ways he has become a bridge that foreigners must cross if they want to reach a deeper understanding of China.

    In the past two decades, the Chinese studies programs have gained huge popularity in Western universities. More recently, the Chinese government has set up Confucius Institutes in more than 80 countries. These schools teach both Chinese language and culture. The main courses of Chinese culture usually included Chinese art, history and philosophy (哲学). Some social scientists suggest that Westerners should take advantages of the ancient Chinese wisdom to make up for the drawbacks of Westerners philosophy. Students in the United States, at the same time, are racing to learn Chinese. So they will be ready for life in a world where China is an equal power with the United States. Businessmen who hope to make money in China are reading books about Confucius to understand their Chinese customers.

    So the old thinker's ideas are still alive and well.  Today China attracts the West more than ever, and it will need more teachers to introduce Confucius and Chinese culture to the West. As for the old thinker, he will not soon be forgotten by people in the West, even if his birthday is.

    Most parents fear getting letters home from their children's school. They are usually informing them that their child is in big trouble. But ahead of the SATs exams next week, one school decided to send a letter of a different type.

    Bosses at Buckton Vale Primary School in Stalybridge sent letter to all pupils in the sixth grade to tell them how special and unique they are. The letter highlights all the natural skills and abilities the pupils have and everything that makes them "smart'' individuals.

    They are told how their laughter can brighten the darkest day and that the examiners do not know the pupils are kind, trustworthy and thoughtful.

    The letter, signed by the headmaster and two other teachers, has been put on the school's Facebook page and shared more than 9. 000 times with more than 7,000 likes.

    The letter reads, "Next week you will sit your SATs tests for maths, reading, spelling, grammar and punctuation. We know how hard you have worked, but there is something very important you must know. The SATs test does not assess all that makes each of you special and unique. The people who create these tests and score them do not know each of you in the way that we do and certainly not in the way your families do. "

    The letter goes on to say that the tests are not the most important thing in life, adding, "The scores you will get from this test will tell you something, but they will not tell you everything. There are many ways of being smart. You are smart!"

    The letter has been welcomed by many parents on Facebook. Lynn McPherson wrote, "That's great instilling (逐步灌输) hope, faith and belief. " And Mary Tilling said, "Every child school receive one of these. Brilliant. "
