    Swiss researchers said Monday they have developed a wireless camera system to monitor vital signs in premature babies, a move that could replace uncomfortable and highly inaccurate skin sensors (传感器) which produce false alarms in up to 90 percent of cases, mainly set off by the baby's movement.

    “This is a cause of discomfort for the babies, because we have to check on them every time,” said Jean-Claude Fauchere, a doctor at University Hospital Zurich's newborn clinic.

    His hospital is preparing to begin tests of a new, contactless system created by researchers at the EPFL polytechnical university in Lausanne and at the Swiss Center for Electronics and Microtechnology.

    The system designed in Switzerland should allow premature babies kept warm in incubators (恒温箱) to be medically monitored using highly sensitive cameras that detect the newborn's pulse by analyzing its skin color, which changes so slightly every time its heart beats.

    “Breathing is monitored by measuring movements of its chest and shoulders. At night, infrared (红外线的) cameras take over, and monitoring can be carried out non-stop,” the statement said.

    The visual system was designed by CSEM researchers, who chose cameras sensitive enough to detect minute changes in skin color, while the EPFL researchers designed algorithms (运算程序) to process the data in real time.

    “We ran an early study on adults, where we looked at a specific part of skin on their foreheads,” EPFL doctoral student Sibylle Fallet said. “With our algorithms we can track this area when the person moves, and use tiny changes in their color to determine the pulse,” she said. “The tests showed that the cameras produced practically the same results as conventional sensors.”

    Once the system has been widely tested on premature babies, it could one day replace skin sensors altogether, the schools said.

    Nov. 21 is World Hello Day. It began back in the 1970s as part of an effort to make the world more peaceful. It was created by the United Nations just after the war between Israel and Egypt in 1973. The philosophy (理念) behind it is: Say “Hello” and stop war.

    It sounds like a fine idea, but most of us know that simply saying “Hello” won't bring about world peace. Still, on a smaller range, the simple act of saying hello to someone can make a lot of difference.

    This might not be obvious. After all, it's such a casual thing and requires so little effort. You raise your head to someone as you pass by them in the school corridor (走廊), say “Hello' then it's over.

    Although we might not realize it, a small thing like a greeting can mean a lot to a person. Many people are lonely because they're shy. They find it difficult to communicate with people, even though they want lo. It leads to them feeling cut off.

    On this basis, maybe it's a good idea, not just on Nov. 21, but every day, to remember to say “Hello” to as many people as we can. The stranger who hears your greeting may secretly smile in their heart. You might even make their day.

    Greeting other people is the easiest way to be polite. Politeness is the way we individual humans link up with the rest of the human world outside of our circles of family and friends. Politeness is one of the aspects of culture that make us a society rather than just many individuals living in the same space.

    No one said it better than the French author Joseph Joubert: “Politeness is the flower of humanity''. A “Hello” to a stranger is a small thing, and often neglected (忽视), but through it we can make the world better for another person.

    If you think American cooking means opening a package and throwing the contents into the microwave oven (微波炉),think again. On the one hand, it's true that many Americans have cold cereal for breakfast, sandwiches for lunch and instant (方便的) dinners. From busy homemakers to working people, many Americans enjoy the convenience (方便) of fast food that can be ready to serve in 10 minutes or less. On the other hand, many Americans realize the importance of cooking skills. Parents—especially mothers'—see the importance of training their children- especially daughter's. Most Americans think that there's nothing better than a good home-cooked meal. But with cooking, as with any other skill, good results don't happen by accident.

    Probably every cook has his or her own way of cooking. But there are some basic skills that most people follow. For example, baking is a main method (方法) of preparing food in America. For that reason, Americans would find it next to impossible to live without an oven. American cooks pay special attention to the balance of foods, too. In planning a big meal they try to include meat, a few vegetables, some bread and often a dessert. They also like to make sure the meal is colorful. Having several different colors of food on the plate usually makes for a healthy meal.

    For those who need guidance in their cooking, or for those who have just run out of ideas, recipes are a great help. Recipes list all the ingredients for a dish (generally in the order used), the amount of each to use, and a description of how to put them together.

    US scientists say they have poured cold water on the theory that washing hands with hot water kills more germs (细菌) than unheated water. The small study of 20 people found using water at 15C (59F) left hands as clean as water heated to 38C (100F).

    National Health Service (NHS) recommends that people wash their hands in either cold or warm water. In this study, scientists at Rutgers University-New Brunswick wanted to find out if popular assumptions about the benefits of warm or hot water and official guidance on hot water — given to the food industry in the US — held true. They asked 20 people to wash their hands 20 times each with water that was 15C (59F), 26C (79F) or 38 degrees (100F). Volunteers were also asked to experiment with varying amounts of soap. Before they started the tests, their hands were covered in harmless bugs. Researchers say there was no difference in the amount of bugs removed as the temperature of the water or the amount of soap changed.

    Prof Donald Schaffner said: “People need to feel comfortable when they are washing their hands but as far as effectiveness goes, this study shows us that the temperature of the water used did not matter.”

    However, the researchers accept their study is small and say more extensive work is needed to determine the best ways to remove harmful bacteria.

    In the UK, NHS experts say people can use cold or hot water to wash their hands. They say hands should be washed for at least 20 seconds and stress the importance of using enough soap to cover the whole surface of the hands. Their guidance focuses on rubbing hands together in various ways to make sure each surface of each hand is clean.

    One of the greatest gifts one generation can give to other generations is the wisdom it has gained from experience. This idea has inspired the award-winning photographer Andrew Zuckerman. He interviewed and took photos of fifty over sixty-five-year olds all over the world. His project explores various aspects of their lives. The photos and interviews are now available on our website.

    Learning Chinese could be one of the most important decisions you ever make. Chinese is becoming the language to learn in the 21st century. With the world's largest population and a rapidly growing middle class, China stands to become the engine of the world's economy in the coming years. This will make learning Chinese very important for people in many industries, or for those of us who wish to visit China or learn from its culture and history.

    There is an ongoing effort to modernize the writing system and standardize the language. An increasing number of people learning Chinese are learning the Mandarin, so unless you absolutely need to learn another dialect (such as Cantonese), be sure you are studying Mandarin.

For native English speakers Chinese is one of the most difficult and most different languages to learn. The vocabulary is wholly unfamiliar and unlike anything we know. In addition, in the Chinese tone system, words are spoken in rising or falling tones, which help to distinguish between them. Furthermore, there is the Chinese writing system— a collection of thousands of individual ideograms (表意文字), or symbols, which represent a word or an idea. These ideograms have no phonetic value—that is to say, we can't tell how the word is pronounced by how it is written. There is a method to present written Chinese in a phonetic script called pinyin. If you are learning Chinese, you'll be working with this pinyin system, but the beauty of the traditional writing system shouldn't be passed up. All these factors make learning Chinese difficult for us. Yet, for a determined learner, there's always a way to overcome it.
