Emily and her boyfriend had just had a fight. She felt alone and hopeless. Then she went into the kitchen and grabbed what she needed before going back up to her room quietly. She switched on the TV and started eating…and eating…for hours, until it was all gone.

     What Emily didn't know at the time was that she was suffering from an illness called binge-eating disorder(BED)(暴饮暴食).

    For years, Emily didn't tell anyone what she was doing. She felt ashamed, alone, and out of control. Why don't famous people confess (承认) to BED, as they do to anorexia? It's simple: There's a stigma（污名）involved. “Overeating is seen as very bad, but dieting to be skinny is seen as positive and even associated with determination," says Charles Sophy, a doctor in Beverly Hills , California.

    "Some parents or friends may look at a teen with BED and think, 'Oh, a good diet and some will-power will do the trick.' But that's not true," says Dr.Ovidio Bermudez , a baby doctor at the Eating Recovery Center in Denver. "Eating disorders are real physical and mental health issues; it's not about willpower." The focus in treating BED shouldn't be on weight, because as with all eating disorders, the behaviors with food are a symptom of something deeper.

    Like most other diseases, genetics may play a big part in who gets BED and who doesn't. If you have a close relative with an eating disorder, that means you're more likely to develop an eating disorder of your own.

    Besides, many people with BED have tried at some point or another to control it by going on a diet, but paying more attention to food doesn't help. And it might even make things worse, like it did for Carla, who's 15 now and is recovering from BED. "My parents would always tease me about my weight, so when I was 14, I went on a very restrictive diet," she says. When you can't have something, you only want it more, so every time Carla would have a bite of something that wasn't allowed on her strict diet. She would quickly lose control and binge (狂欢).

    Next time you make yourself a hot cup of tea or coffee, you might want to let it cool down a bit before drinking.

    Researchers say letting your hot drinks cool off could help you avoid some kinds of cancer. Researchers at the International Agency for Research on Cancer (IARC) found evidence that drinks at temperatures above 65℃, when swallowed, can cause cancer of the esophagus (食道). The researchers examined findings from other studies where tea and coffee were often served at 70℃ or above. Those studies were completed in Iran, China and South America.

    In developed countries, health experts have linked esophageal cancer to smoking and alcoholic（酒精）drinks. However, this form of cancer is more common in areas where people drink beverages（饮料；酒水）at very high temperatures.

    In Europe and the United States, many people drink coffee and tea at temperatures around 60℃.And they often add milk which lowers the temperature greatly. However, tea-drinkers in Iran and mate-drinkers in South America often enjoy their beverages at closer to 70℃.

    The researchers find that South Americans not only drink their mate very hot, they also drink it through a metal straw(吸管). This sends the scalding liquid directly into the throat.

    The findings, however, are good news for coffee drinkers. In 1991, the World Health Organization listed coffee as possibly carcinogenic (致癌的).” The WHO officials have since changed their position on that listing. They now suggest that the temperature of your hot drink is a greater risk factor than the actual drink itself.

    The results suggest that drinking very hot beverages is one probable cause of esophageal cancer and that it is the temperature, rather than the drinks themselves, that appears to be responsible.

    A new study shows students who write notes by hand during lectures perform better on exams than those who use laptops.

    Students are increasingly using laptops for note-taking because of speed and legibility(清晰度).But the research has found laptop users are less able to remember and apply the concepts they have been taught.

    Researchers performed experiments that aimed to find out whether using a laptop increased the tendency to make notes "mindlessly" by taking down word for word what the professors said

    In the first experiment, students were given either a laptop or pen and paper .They listened to the same lectures and were told to use their usual note-taking skills. Thirty minutes after the talk, they were examined on their ability to remember facts and on how well they understood concepts.

    The researchers found that laptop users took twice as many notes as those who wrote by hand. However, the typists performed worse at remembering and applying the concepts. Both groups scored similarly when it came to memorizing facts.

    The researchers' report said, "While more notes are beneficial, if the notes are taken mindlessly, as is more likely the case on a laptop, the benefit disappears."

    In another experiment aimed at testing long-term memory, students took notes as before but were tested a week after the lecture. This time, the students who wrote notes by hand performed significantly better on the exam.

    These two experiments suggest that handwritten notes are not only better for immediate learning and understanding, but that they also lead to superior revision in the future.

    Three magical destinations just one day!

    TOUR DETAILS

    Windsor Castle

    Time-honored in history, Windsor Castle is proudly located on a wooded hill overlooking the Thames River. Dating back to Norman times, it is famous for sweeping landscaped gardens, which is easy to see why it's the Queen's favorite week place. Famous for its architecture and Royal palace, the Castle was built in the 11th century after the Norman invasion. It's home to priceless artworks and you can visit Queen Mary's Dolls' House. Remember don't miss the ceremony—Changing of the Guards.

    Stonehenge

    Stonehenge is located in the county of Wiltshire. This is your chance to see a side of the world-famous stones that most people don't get a chance to see! You will never forget your first glimpse of grand Stonehenge with its rocks rising up against the skyline on Salisbury Plain. There are many unsolved mysteries about the rocks. Was Stonehenge intended as a religious temple? A clock for astronomy? A burial ground? Make up your own mind as you explore this unique site that has confused the world for 5, 000 years.

    Bath

    Beautiful Bath was the first city in England to be added to the UNESCO World Heritage List. No tour of Bath would be complete with a visit to the famous Roman Baths that gave the city its name. This beautifully preserved bathing site still has flowing water from Brain's only hot spring. You will be amazed by the impressive torch-lighting ceremony as dusk falls. You can also have a taste of Bath's water in Pump Room, where hot waters are drawn for drinking.

When we meet someone for the first time, we usually get a vague sense of what kind of person they are by the way they shake hands, talk, or walk. In the age of social networking, however, first impressions are sometimes made even before we actually meet someone in person—that is, by looking at their profile photo.

    According to a recent study, these social images say a lot about our personality. In the study, presented in a paper at the International AAAI Conference on Web and Social Media, a group of researchers from the University of Pennsylvania in the US used software to analyze the profile pictures of 66,000 users of US social platform Twitter and 3,200 of their tweets. At the same time, about 434 participants were asked to complete a survey about their personality type. The researchers wanted to find out if there was a connection between personality traits—like openness, extroversion, and neuroticism(神经质)—and a person's profile picture.

    According to the results, open people are more likely to pose in an unusual way and use objects such as glasses or a guitar in their profile photo because they enjoy new and exciting experiences. Meanwhile, neurotic people often hold back their negative emotions. They try to avoid showing their face；Instead, they use an image of something like a pet, a car or a building.

    Apart from the objects in profile pictures, the colors used in them also give us some hints about the photo's owner. For example, extraverts were found to have the most colorful profile images, as they want to emphasize their personality and show themselves off, the researchers wrote.

    Although social media photos "usually represent an extension of one's self, they also allow a user to shape his or her own personality and idealized view," according to the researchers. So, when choosing a profile photo, maybe we should ask ourselves first what kind of image we'd like to convey. After all, first impressions always last.

This winter, the U. S. state of California received unusually large amounts of rain and snow. Now, people worry that some areas will flood as the snow in the Sierra Nevada Mountains melts (融化).

Ron Caetano lives about half-way between the cities of Los Angeles and San Francisco. He is preparing to leave in case his community, called the Island District, floods.

More than 100 years ago, the Island District area was under a large lake named Tulare Lake. At one time, Tulare Lake was the largest freshwater lake west of the Mississippi River. But reservoirs (水库) and watering systems for agriculture caused it to disappear. However, in very rainy years, farmland can still get covered with water.

Experts say reservoirs near the area will likely receive three times more water than they can hold this year. That means officials must increase the amount of water they release (释放) from the reservoirs. If too much water is released, the area might flood.

The Island District has organized a community network to help prepare for floods. People are placing sandbags close to elderly neighbors' houses to block possible flooding. And they are looking at reports from water officials, county officials, and from each other.

California has had very dry weather in recent years. Both cities and farm communities acclaimed this year's winter rains. If the weather gets warmer slowly, the snow will not melt quickly and there may be little or no flooding. But if the weather gets hot quickly, that will bring trouble from too much melting snow.

Officials announced plans to close parts of Yosemite National Park because of threats of flooding. The park is about 270 kilometers east of San Francisco in the Sierra Nevada Mountains.

Nicholas Pinter is with the University of California, Davis Center for Watershed Sciences. He said the lake's size has always changed because of California's weather. He described the surrounding area this way. "It has been an engineering problem all along," he said. "This is a bathtub (浴缸) with no way out."
