Watching a 3D movie can more than double the concentration powers and cognitive(认知) processing of children, a new research claims.

    A study made by visual technology firm RealD and led by child psychologist Dr. Richard Woolfson suggests that children aged between 7 and 14 experienced twice the cognitive processing speed and performed better in testing after watching 20 minutes of a 3D film. This is despite suggestions that attention spans(时期) in children have shortened in the last decade due to unlimited to access to entertainment, including on-demand TV, gaming and social media. A 2015 study claimed that watching 3D content had a similar effect to brain-training exercises.

    Consumer psychologist Mr. Fagan said that the increased stimulation(刺激) found in watching something in 3D "exercised" the brain and improved performance in the short term. "3D films can play the role of ‘brain-training' games and help to make children ‘smarter' in the short term," he said. "The shortening of response times after watching 3D was almost three times as big as that gained from watching 2D; in other words, 3D helps children process aspects of their environment more quickly. This is likely to be because 3D is a mentally stimulating experience which ‘gets the brain's juices flowing'."

    The experiment saw children given a range of cognitive tests before watching 20 minutes of a movie in either 2D or 3D and being tested again. The results showed those who saw the 3D content reacted faster and performed bettering the second round of testing. Mental engagement also rose by 13% among 3D watchers. Child psychologist Dr. Woolfson added that “supportive parenting” and regularly listening to classical music can also aid a child's memory.

    Scientists are studying different foods, and they will see which foods protect us from cancer(癌症), and which cause it. It is known that a healthy diet(饮食) will help keep a healthy body weight, which can also decrease the risk(风险) of many types of cancer.

    Fruit and vegetables

    Fruit and vegetables are an important part of a healthy diet. They can decrease the risk of some cancer types like mouth and throat cancer. They are a good source of many important nutrients such as vitamin A, vitamin C, vitamin E, and are an excellent source of fiber.

    Our advice

    Try to get plenty of fruit and vegetables in your diet. Eating fruit and vegetables with a variety of colors will help you get many kinds of vitamins and minerals, as the chemicals that give these foods their colors are good for you.

    Meat

    Eating lots of red and processed meat can increase(增加) your risk of stomach cancer. Red meat includes all fresh and frozen beef, pork and lamb. Processed meat includes ham, bacon and sausage. White meat, such as chicken, is unlikely to increase your risk of cancer.

    Our advice

    Eat smaller and fewer parts of red and processed meat. Try using beans or peas instead of meat in your diet. When you cook meat, use low-temperature methods.

    Fat

    Fat is a necessary part of our diet but high-fat diet can increase our risk of cancer, heart disease and other diseases. Meat is higher in saturated fat(饱和脂肪) and eating too much saturated fat may increase your risk of breast cancer.

    Our advice

    Try not to eat too much fatty foods. In particular, try to cut down on saturated fat contained in fatty meat, biscuits, and butter. Try to avoid frying foods in lots of oil.

    More and more people in America are celebrating the Indian holiday Diwali. Diwali is Hindi for "row of lights". It is the most important holiday in India.

    Many people around the world are beginning to celebrate it as well. The United States is one of the places where the festival is becoming more common. Diwali celebrations can now be found at American landmarks like Disneyland in California and New York City's Times Square. They are also held in many parks and museums.

    Neeta Bhasin created the Times Square event. She said Indian immigrants have found great success in America. But, she said, many Americans still do not know much about India. So, she decided to act." I felt it's about time that we should take India to mainstream America and show India's rich culture, heritage, arts and variety to the world," she said, "and I couldn't find a better place than Times Square."

    Bhasin came to the United States from India 40 years ago. She is president of ASB Communications, the marketing firm behind Diwali at Times Square. Tens of thousands of people attend the event, now in its fourth year.

    In India, Diwali is a five-day harvest festival held just before the Hindu New Year. The exact dates change from year to year but Diwali is always in the fall. Celebrations include lighting oil lamps or candles called "diyas".

    A Diwali celebration will light up Disney California Adventure Park in Anaheim this year. Visitors can watch performances of traditional Indian dances and take part in a Bollywood dance party. The event is part of a Festival of Holidays program at the theme park to show cultural traditions from around the world. The program takes place on November 10th through January 7th.

    San Antonio, Texas, also holds a Diwali celebration. And it is one of the nation's largest celebrations, with more than 15,000 people in attendance each year. Visitors can enjoy Indian dance，food and fireworks. Organizers also plan to float hundreds of lighted candles in the San Antonio River, along the city's famous River Walk.

    Why does time seem to fly by faster as we get old? You've got your aging brain to blame. This is likely due largely to the physical changes of our nerves and neurons (神经元). New research suggests 'rapid fire' abilities of the young brain allow us to process more information during youth, causing the days to seem longer earlier in life. However, as we get old, researchers say the older brain takes more time to process information.

    The new finding put forward by a Duke University researcher was published in a paper in the journal European Review this week According to Adrian Bejan, the J. A Jones Professor of Mechanical Engineering at Duke, the physical changes of our nerves and neurons play, a major role in our perception (知觉) of time as we get old. Over the years these structures become more complex and eventually begin to degrade.

    "Little babies, for example, move their eyes much more often than adults because they're processing images at a faster rate," Beian says, For older people, this means fewer images are being processed in the same amount of time, causing experiences to seem as though they're happening more quickly.

    Life is full of surprises and events that sometimes change one's daily routine. Some of them might be good and pleasant. {#blank#}1{#/blank#} For example, during an examination, you discover that you don't know the answers; one morning you are suddenly told that you get fired from your job. These unexpected events may cause anxiety and stress. So you need to find some ways to be less affected by them.

    {#blank#}2{#/blank#} Even if you live the same kind of life, doing the same things day after day, there could be unexpected events. So you need to realize that such events can't be avoided and you need to be prepared for them. In this way, you'll find it easier to deal with whatever happens in your life.

    Have a positive attitude. Not all unexpected events are bad. {#blank#}3{#/blank#} For example, even getting fired for work could finally turn out well, as you might find a more satisfying job.

    Introduce small changes into your life. {#blank#}4{#/blank#} You can try eating a different breakfast or drink tea in the morning instead of coffee, or do things that you usually do, but in a different way.

    Always focus on the present moment, learning from it and making use of new changes that come your way. In other words, make the most of the present moment, instead of thinking about what you lost, or how bad the situation is. {#blank#}5{#/blank#}

    Leaving a good impression can be done in different ways, from clothing to posture, and from talking style to body language. Below are several tips for you to begin with:

    ●Physical appearance matters. We're visual creatures after all.

    Physical appearance is the first clue one relies on to judge who we are. {#blank#}1{#/blank#} It also means the person means something to us by dressing properly. If it is a business setting, be aware of the dress rule or culture. {#blank#}2{#/blank#} A thumbs-up here does not mean the same elsewhere. So do the research! Details from any little areas will affect the impression on the whole.

    ●{#blank#}3{#/blank#}

    A fake (假的) smile can potentially do more harm than good in our attempts to leave a good impression. It is understandable that sometimes it is hard to suddenly force a smile. {#blank#}4{#/blank#} Remember being positive plays an important part in shaping our first impression.

    ●Look into people's eyes until you see the colors of their iris (虹膜).

    Keeping eye contact delivers a sense of friendship to the people we interact with. Consequently, they feel more connected to us and tend to be more positive toward the interaction. {#blank#}5{#/blank#} Well, try to identify the color of the others' irises. Get it? That makes a good eye contact example.

    Are these the impression we want to leave? Stop staring at the ground and look at people in the eye then!
