According to body language expert Robert Phipps, the way people sleep at night actually determines a lot about the type of personality they have. Phipps has identified four sleeping positions that affect personality.

    Phipps found that worriers, those who stress the most, tend to sleep in the fetal (胎儿的) position. He found that this is the most common bedtime position, with nearly 58 percent of people sleeping on their side with knees up and head down. The more we curl up (蜷曲), the more comfort we are seeking, according to Phipps.

    The second most common position is the log. Sleeping with a straight body, with arms at each side, as if they are standing guard at Buckingham Palace, indicates stubbornness, and these people (the 28 percent who sleep this way) often wake up stiffer than when they went to sleep.

    “The longer you sleep like this, the more rigid your thinking is and you can become inflexible, which means you make things harder for yourself,” according to Phipps.

    Yearner (向往) sleepers are next on the list. About 25 percent of people sleep in this style—on their side with arms stretched out in front, looking as if they are either chasing a dream or perhaps being chased themselves. Yearners are typically their own worst critics, always expecting the best results, explained Phipps. These people often wake up refreshed and eager to face the challenges of the day ahead.

    Perhaps the most peculiar (奇怪的) of sleep styles is the freefaller position. This sleep style makes up 17 percent of the population. They sleep face down with arms stretched out. These people, according to Phipps, feel like they have little control over their life. Not only is this the strangest of sleep styles, but also the least comfortable, and people may wake up feeling tired and have no energy.

    Inconclusion, Phipps has only one more thing to add: “A good night's sleep set you up for the following day and our sleeping positions can determine how we feel when we wake.”

    Cancer is a leading cause of death around the world.

    When it comes to cancer, the sooner you know you have it, the better your chances of surviving are.

    A new blood test could change the way doctors and researchers find cancer in patients. Researchers say the test could provide some hints of the early forms of the disease.

    Gareth Jenkins is a professor at the University of Swansea. He says he and his team did not look for cancer. They instead looked for a by-product of cancer, mutated (突变的) red blood cells. They looked for, what Jenkins calls, the collateral (附带的) damage of cancer—the damage left by the disease.

    “In this blood test we don't measure the presence of cancer，we measure the presence of mutated red blood cells which are the collateral damage that occurs—a by-product of the cancer developing.''

    The researchers used normal laboratory equipment to perform the tests. This equipment looks for changes in the structure of millions of red blood cells. Those mutated cells lack a surface protein (蛋白质) that healthy cells normally have.

    “The goal of the test is looking for very rare cells which have picked up a mutation. The number of mutated red blood cells in a healthy person is around 5 or so mutated cells per million; so, you have to look at millions of red blood cells to discover those rare events. The number increases in cancer patients—it goes up to 40 or 50 on average.”

    The researchers tested blood from about 300 people, all of whom have cancer of the esophagus (食管). Patients with esophageal cancer have high levels of mutated red blood cells. Jenkins says that at this point he is not sure if other cancers would produce similar results.

    The hope is that the new test could one day become part of commonly used medical methods to find out if a person has cancer. These new technologies could save millions of lives.

    A long-term American study shows the importance of early education for poor children. The study is known as the Abecedarian Project. It involved more than one-hundred young children from poor families in North Carolina.

    Half of the children attended an all-day program at a high-quality child-care center. The center offered educational, health and social programs. Children took part in games and activities to increase their thinking and language skills and social and emotional development. The program also included health foods for the children.

    The children attended the program from when they were a few weeks old until the age of five years. The other group of children did not attend the child-care center. After the age of five, both groups attended public school.

    Researchers compared the two groups of children. When they were babies, both groups had similar results in tests for mental and physical skills. However, from the age of eighteen months, the children in the educational child-care program did much better in tests.

    The researchers tested the children again when they were twelve and fifteen years old. The tests found that the children who had been in the child-care center continued to have higher average test results. These children did much better on tests of reading and mathematics.

    A few years ago, organizers of the Abecedarian Project tested the students again. At the time, each student was twenty-one years old. They were tested for thinking and educational ability, employment, parenting and social skills. The researchers found that the young adults who had the early education still did better in reading and mathematics tests. They were more than two times as likely to be attending college or to have completed college. In addition, the children who received early education were older on average, when their first child was born.

    The study offers more evidence that learning during the first months and years of life is important for all later development.

    The researchers of the Abecedarian Project believe their study shows a need for lawmakers to spend money on public early education. They believe these kinds of programs could reduce the number of children who do not complete school and are unemployed.

    Recently we made a survey and asked a large number of people to tell us about their teachers. Here is what they remembered about their teachers:

    "What teachers do I remember? Well, I remember my first teacher. She was so kind and pretty, and she told us many interesting stories."

    "I remember an English teacher —— he always had colored socks: red, green, even orange."

    "I remember a math teacher. She always dressed very well. I couldn't stop looking at her. I wanted to be like her."

    "Our chemistry teacher. He was so strict. We were afraid of him. I don't think he liked us."

    "The physics teacher was so boring. He could make us fall asleep very quickly!"

    "One year we had a really good Chinese language teacher. He was very patient and told very funny stories. He was popular with all the class. We always worked hard for him. We are his friends."

    "The PE teacher always said I was stupid. I thought teachers should give us encouragement. I am not interested in sports because of him."

    "I had one history teacher who always wore clothes of the same color. During the three years, I never saw him change."

    "I remember two teachers well. One was my music teacher who was very active, and usually had a loud voice. The other was my computer teacher who was very serious, but he really helped me when I had problems at any time."

    Janet Guthrie and Danica Patrick, first female Indy competitor and winner

    No complaints about woman drivers. Janet Guthrie, an space engineer who was training to be an astronaut, turned to car racing when she was cut from the space program for not having completed her doctors degree. In 1977, Guthrie became the first female Indy 500 competitor. She didn't take the lead, but Danica Patrick did. In 2005 and in 2008, Patrick became the first woman ever to win an Indy Car Series.

    Raymonde de Laroche, first female licensed pilot

    A former actress who'd been born Elise Raymonde Deroche in Paris in 1882, Raymonde de Laroche was inspired to take up flying after seeing the Wright Brothers flight demonstrations in 1907 in France. Though she wasn't the first female pilot, de Laroche was the first woman to earn a pilot's license in 1910.

    Gertrude Ederle, first woman to swim across the English Channel

    On August 6. 1926. Gertrude Caroline Ederle became the first woman to swim across the English Channel. Ederle, who lived to be 98 and died in 2003, was also an Olympic swim champion and five-time world record-holder in five swimming events

    Kathrine Switzer, Nina Kuscik and Joan Benoit, first major female marathoners.

    In 1967, 20-year-old Kathrine Switzer became the first woman to run in the Boston Marathon, even though race officials had tried to stop her. Nina Kuscik became the first woman to officially win the Boston Marathon, 1972. In 1984, American Joan Benoit became the first winner of the Women's Olympic Marathon, finishing 400 meters ahead of Norway's Grete Waitz.
