More over smart phone, the intelligent watch is about to take your spot as the latest hi­tech current, allowing wearers to glance at messages and even take calls without touching their phones. The i'm Watch, available since 2011, is the flagship product of an Italian company—i'm. This smart watch is an assist to the smart phone, with which it can communicate by Bluetooth wireless technology. It means you can leave your phone in your pocket as you answer or reject a call, review e­mails or read updates from friends on Twitter or Facebook.

    The i'm Watch also has its own applications, such as i'm Sport, which links with a heart rate detector (检测器) to allow a runner to check his pulse. Such functions already exist in specialized sports watches but not on watches that are linked to smart phones.

    With a square shape, a 3.8­centimeter touch screen and various colors, the i'm Watch sells for a minimum of 300 Euros ($390) for the basic model and prices climb to 16 000 Euros for a luxury model in silver or decorated with diamonds.

    So far, the watch has already found 30 000 buyers, 80 percent of whom are men aged 25 to 50. “Seventy percent are iPhone users, 25 percent Samsung and the rest are other telephones using Google's Android operating system，” said Massimiliano Bertolini, a manager of the company, which aims to sell more than 200 000 watches this year. The company's target market is the person who is always glued to his smart phone, even in meetings or at the movies, or people who wish to keep an eye on their heartbeat during exercise. They will especially target women with advertisements emphasizing its design rather than its technology.

    A new research shows that in Britain more and more people are returning to the old tradition that the whole family has a meal at table. Worrying about the obesity(肥胖症) and breakdown of a family, people change their eating habits so greatly, according to analysis. They find the number of the family having a meal together increases by 5% from 2002 to 2004, and most people who have meals with their family come from the rich social class.

    The new discovery makes doctors and the people struggling against obesity extremely excited. Giving up the tradition that the whole family have a meal together is exactly one of the reasons for a series of problems including children's overweight. If a child has a meal in front of the television or the computer alone, he will often eat some fast food.

    Jason Collins is one of the persons returning to the old tradition. Collins is a manager of a bake house. He finds after he gets used to having a meal at home with his child, the child becomes much more obedient(听话的). Dr. Jin is a child psychologist, and she expresses welcome to this result of the study. She says it can make parents have a very good chance to chat with the child when the whole family have a meal together.

    Cultures are based on social and linguistic(语言的) communities.

    In South Africa, we exist amongst diverse groups which are culturally different. This makes us multicultural. Toit, one sociologist in the U.S., explains that multiculturalism is more than the expression of cultural variety, and it also concerns communication. He adds that for multiculturalism to “succeed”, meaningful communication is a requisite.

    In multicultural countries, it is necessary that the education system encourages learners to become interculturally competent (胜任的). The process of becoming intercultural is a “personal transformation” from being cultural to being intercultural. This does not mean that a highly intercultural person's identity is culture-free. Rather, it is not rigidly bound by membership to anyone particular culture. Furthermore for learners to become interculturally competent, it is necessary that all involvers in the education system become aware of their own cultural background.

    Toit conducted a survey, the objective of which was to determine the problems experienced by learners in a multicultural learning environment. Two hundred questionnaires were administered. 55% believed that different values and beliefs were a major cause of the communication problems. Closer examination of the interactions showed that learners were in fact mostly associating with members of their own cultural groups. Toit points out that in an intercultural communication, people would be challenged by the sudden difference in culture, and this may force an evaluation or re-evaluation of their beliefs and values. 45% of the learners believed that there was lack of trust among their peers. The general lack of trust between two complete strangers leads to an uncomfortable situation. They said that when learners are asked to work in groups, they are unwilling to do so. They added that one of the many issues that contribute to such negative opinions was the language barrier.

    Shree Bose is one of the most impressive kids graduating from Fort Worth Country Day High School this year. Bose has a large circle of friends, and there's one who you may have heard of: President Obama. He has twice publicly recognized her achievements in cancer research and spoken with her in the Oval Office.

    If that isn't enough, Bose recently gave a TED Talk about her work with the cancer drug Cisplatin, which also won her first prize at the Google Science Fair and recognition as one of Glamour magazine's Young Amazing Women of the Year.

    After watching her grandfather struggle with liver cancer, Bose was determined to help out in any way she could. As a high school student though, her scientific choices were limited. She reached out to various hospitals and research centers, but doctors turned down her requests because they felt she was too inexperienced medically.

    Only the North Texas Science Health Center respected her determination and chose to guide her. The results were amazing.

    Bose chose to study a protein (蛋白质) and its reaction with the cancer drug Cisplatin. She noticed that when she prevented this protein from growing, Cisplatin was allowed to begin destroying cancer cells once again.

    “My project not only contributes to the understanding of the relationship between the protein and Cisplatin, but also suggests a newer, more effective treatment for patients who resist Cisplatin,” Bose said.

    Bose's achievements aren't limited to the lab, though. She was also captain of her swim team and editor-in-chief of her school paper.

    Bose is currently getting practical experience at the National Institute of Health and she'll be attending Harvard in the fall. She plans to study molecular biology and go to medical school. Eventually, she would like to be a doctor.

    Filled with much housework, meals and childcare at home, many people feel that being at work sounds more like having a picnic. Even for those who have a happy family life, they feel actually more stressed at home than at work.

    Recently, a study carried out by the researchers at a university in the USA found lower levels of hormone released in response to stress in a majority of subjects when they were at work compared to when they were at home. This was true for both men and women, and parents and people without children.

    Both men and women showed less stress at work. But women are more likely to report feeling happier there. Men were more likely to feel happier at home. Experts say there are other reasons why work is less stressful than home for many. “Paid work is more valued in society,” said Sarah Damaske, the lead researcher on the study, “Household work is boring and not particularly rewarding.”

    We get better at our job with time and the increased competence means less stress and more rewards. Yet none of us, no matter how long we've been doing it, ever truly feels like an expert at parenting or even at marriage.

    The support and friendship of co-workers also offer stress relief. At home, meanwhile, stress spreads and increases quickly. “That's the reason why most housewives wish they were the bread earners,” Dr. Damaske says.

    Much of the advice to families and couples includes the warning to “leave work stress at office” and even to change our mind-set from work to home, for example, a walk around the block. The recent findings, though, suggest our home life, not our attitude, might be due for some change.

    Some kinds of mental skills naturally decrease as people get older. Yet research seems to show that some training can improve such skills. A recently published study also appears to attest that the good effects of training can last for many years after that training has ended.

    Researchers at Johns Hopkins University in Maryland wanted to learn how long memory and thinking skills would last in older people who were trained to keep them. The people were part of the ten-year research project. They were taught methods meant to improve their memory, thinking and ability to perform everyday tasks.

    More than 2,800 volunteered for the study called ACTIVE ­ short for Advanced Cognitive Training for Independent and Vital Elderly. Most were studied when they were more than 70 years old.

    The volunteers took one of several short training classes meant to help them keep their mental abilities. One class trained participants in skills including how to remember word lists. Another group trained in reasoning. A third group received help with speed-of-processing ­ speed of receiving and understanding information. A fourth group ­ the control group did not get any training.

    Earlier results had established that the training helped the participants for up to five years. Now, leading study writer George Rebok says, the research showed most of the training remained effective a full ten years later.

    Professor Rebok and his team found that the people trained in reasoning and speed-of- processing did better on tests than the control group.

    "We are wondering whether those effects which endured over time would still be there ten years following the training, and in fact, that's exactly what we found.

    The effect on memory, however, seemed not to last as long. Still, the old people in any of the three classes generally reported less difficulty in performing daily activities than the control group. The total training time for the older people was between 10 and 15 hours.
