People who smoke could lose around one third of their everyday memory, researchers say.

    A study by a team at the University of Northumbria has shown that smokers lose more of their memory when compared to non-smokers. And the research also found that those who kicked the habit saw their ability to recollect information restored to almost the same level as non-smokers.

The study involved more than seventy 18-to 25-year-old volunteers and included a tour of the university's campus. Those who took part were asked to recall(回忆；回想)small details, such as music acts listed to play at the students' union and tasks completed at various points—known as a real-world memory test.

    Smokers performed badly, remembering just 59 percent of tasks. But those who had given up smoking remembered 74 percent and those who had never smoked recalled 81 percent of tasks.

    Dr. Tom Heffernan, who leads Northumbria University's Collaboration for Drug and Alcohol Research Group, said the findings would be useful in anti-smoking campaigns. He said, “Given that there are up to 10 million smokers in the UK and as many as 45 million in America, it's important to understand the effects that smoking has on everyday cognitive function.”

    This is the first time that a study has set out to examine whether giving up smoking has an effect on memory. We already know that giving up smoking has huge health benefits to the body, but this study also shows how stopping smoking can bring a series of benefits to cognitive function. The research will now investigate the effects of second-hand smoking on memory, while Dr. Heffernan will look into third-hand smoking, such as toxins (毒素) left on curtains and furniture.

    Here are six steps to better studying.

Pay attention in class

    Do you have trouble paying attention in class? Are you sitting next to a loud person? Tell your teacher or parents about any problem that is preventing you from paying attention.

Take good notes

    Write down facts that your teacher mentions or writes on the board. Try to use good handwriting so you can read your notes later. It's a good idea to keep your notes organized by subject.

Plan ahead for tests and projects

    Waiting until Thursday night to study for Friday's test will make it hard to do your best. One of the best ways to make sure that doesn't happen is to plan ahead. Write down your test dates. You can then plan how much to do after school each day, and how much time to spend on each topic.

Break it up

    When there's a lot to study, it can help to break things into several parts. Let's say you have a spelling test on 20 words. Instead of thinking about all of the words at once, try breaking them down into five-word groups and work on one or two different groups each night.

Ask for help

    You can't study effectively if you don't understand the material. Be sure to ask your teacher for help. If you're at home when the confusion occurs, your mom or dad might be able to help.

Sleep tight

    So the test is tomorrow and you've followed your study plan—but suddenly you can't remember anything! Don't panic. Your brain needs time to digest all the information you've given it. Try to get a good night's sleep and you'll be surprised by what comes back to you in the morning.

    Dazha Crabs from Yangcheng Lake

    With the Mid-Autumn Festival coming, the time for crabs is around the corner! Dazha Crabs from Yangcheng Lake in China are believed to be the best freshwater crabs.

    “They are delicious, because the bottom of Yangcheng Lake is hard and the crabs grow strong by walking on such a hard surface,” said one sales manager in Suzhou.

    Li Lei, a crab lover from Beijing, said “It's very delicious! But there are too many fake Yangcheng Lake Dazha Crabs”.

    “Maybe the crabs from other regions can appear to be glistening green back, white belly after people wash them, but the golden fine hair on crab claws is still a point of pride and is exclusive to Dazha Crabs from Yangcheng Lake,” said the manager.

    The best time for enjoying them is during September and October of Chinese lunar calendar. “When the season for crabs arrives, the Dazha Crabs from Yangcheng Lake are flown to various cities so that people's appetites can be satisfied,” said the sales manager. “They are really expensive here, sometimes more than 320RMB/500g, 10% of my salary!” said Li Lei.

    Dazha Crabs are usually steamed or boiled for within 20 minutes before they come on the dinner table. They are often enjoyed with vinegar mixed with minced ginger to add flavor and get rid of the cold. People who are particular about how they eat crabs also need to have high-grade Shaoxing rice wine to warm their stomachs.

    There is much work required to eat crabs. So much shell!Most people use both hands and teeth while eating Dazha Crabs. “The eating way is not graceful or elegant,” said Huck. “However, some professionals of eating crabs can use tools to take all the meat out of the crab without damaging a single bite and the crab can be restored to its original shape if the empty shells are pieced together!” said Han Mei, another Dazha crab lover.

    We all know the feeling: looking at the computer screen, pretending to be interested in our homework, even though we really feel bored. But such feelings may soon be at an end, says Dr. Harry Witchel, head of the Essex Medical School. He believes that computers of the future will notice when people feel bored and even take action to stopit.

    Before you get concerned, the machine won't be reading your mind. It will be observing the many movements you make while using a computer. It's not interested in the big movements needed to use the machine — like moving a mouse or touching a screen — but small, barely noticeable movements like closing your eyes, moving in your seat or rubbing your face. Witchel calls these “boredom movements" and says they show how interested the person is in what they are reading or watching. The higher the interest level, the less movement!

    To test his theory, Witchel invited 27 people to perform various computer-based tasks. The activities ranged from playing online games (an interesting task) to reading documents like government laws that most people would find boring.

A special video camera followed the participants' movements as they completed each task. Just as the researcher expected, the “boredom movements" greatly decreased, by as much as 42%，when the subjects were very interested in what they were reading or seeing.

    Fortunately, Dr Witchel isn't planning to use his results to create machines that report students who are not paying attention at school. Instead, he wants “movement sensing” technology to be built into future computers in order to improve students' computer-based learning experience.

    The scientist says that by measuring the students' interest level as they work, educators will be able to adjust their materials in real-time to keep students focused. Witchel also believes that the technology can provide filmmakers with honest audience opinions and in the future, help to develop more intelligent robots.

    Your colleague's sharp comment keeps replaying in your mind. Two of your students are trapped in a "he said/she said" battle. When you reflect on your emotional reactions, you sometimes get caught up in cycles of negative feelings, which can make you feel even worse. If so, the answer may lie in a skill called "self-distancing", the ability to take a step back and view yourself more objectively. According to a research, when people adopt self-distancing while discussing a difficult event, they make better sense of their reactions, experience less emotional suffering, and display fewer signs of stress.

    But what might self-distancing look like in action? Consider a typical "he said/she said" student conflict where they are each focusing on their own feelings. One is thinking, "I can't believe he did that to me." And another insists, "She really hurt my feelings." However, if you ask them to take the self-distancing, they might step outside of themselves and ask broader questions: "Why was he so hurt in this situation?" or "How did her anger affect him?"

    Although this approach may sound too simple to be effective, studies indicate that a change in point of view can have a powerful effect on the way people think, feel, and behave. Here are several different techniques you can try.

    First, consider how a thoughtful friend might respond after quietly observing their situation. Besides, avoid using the pronoun "I". Focus on using third-person pronouns, he, she, they, and they were able to see the stressful event as challenging rather than threatening. Finally, ask yourself, "How would I feel about this one week from now or ten years from now?" This form of mental time travel may be effective because our attention is directed away from our immediate, concrete circumstances.
