My husband hasn't stopped laughing about a funny thing that happened to me. It's funny now but it wasn't at the time.

    Last Friday, after doing all the family shopping in town, I wanted a rest before catching the train, so I bought a newspaper and some chocolate and went into the station coffee shop — that was a cheap self-service place with long tables to sit at. I put my heavy bag down on the floor, put the newspaper and chocolate on the table to keep a place, and went to get a cup of coffee.

    When I went back with the coffee, there was someone in the next seat. It was one of those wild-looking youngsters, with dark glasses and worn clothes, and hair colored bright red at the front. Not so unusual these days. What did surprise me was that he'd started to eat my chocolate!

    Naturally, I was annoyed. However, to avoid trouble — and really I was rather uneasy about him — I just looked down at the front page of the newspaper, tasted my coffee and took a bit of chocolate. The boy looked at me closely. Then he took a second piece of my chocolate. I could hardly believe it. Still I didn't dare to start an argument. When he took a third piece, I felt more angry than uneasy. I thought, "Well, I shall have the last piece." And I got it.

    The boy gave me a strange look, and then stood up. As he left he shouted out. "This woman's crazy!" Everyone stared. That was embarrassing enough, but it was worse when I finished my coffee and got ready to leave. My face went red — as red as his hair — when I realized I'd made a mistake. It wasn't my chocolate that he'd been taking. There was mine, unopened, just under my newspaper.

    When my students ask me why I live in a tiny house, they ask it in light of all the “sacrifices(牺牲)”I an making. They know that I have moved from a large apartment in the city to a small custom-built home on wheels in the backyard woods. They know I forego running water, Internet connection, sewage(下水道), and reliable phone reception.

    However, it was possible for me to be truly happy while living with very few material things. My body responded well, in health, fitness and mood, to a schedule more consistent(一致的)with the natural day and night cycle. Observing the daily sunset, hosting friends for days at a time, reading, writing letters to my families and friends and exploring natural wonders in my spare time all were free and invaluable experiences.

    What was necessary to my survival proved to be a rather short list-healthy food, clean and drinkable water, heat source, weather-protecting shelter, weather-suitable clothing, equally important friends and mental and physical stimulations(刺激).

    When I returned to life in the US, I couldn't help but sense a deep and uneasy belief that life suddenly changed. I felt disconnected with many things- the earth, others, my food source, my waste disposal, the natural cycle of my body and the productive interests. These are the things I once cared for but now find myself too busy to enjoy. How was it that I was earning literally 40 times my Peace Corps salary and was less healthy, satisfied and intentional in my daily schedule? I found myself asking-what is it to be rich anyway? Therefore, last August I let go of most of my possessions and moved into a tiny house on wheels because I wanted to see if I could live a more enjoyable lifestyle. So far so good. No inconvenience has made up for the many positive benefits that continue to come from this change in lifestyle. I believe that I have made the right decision.

    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.

    People from East Asia tend to have more difficulty than those from Europe in distinguishing facial expressions — and a new report published online in Current Biology explains why.

    Rachael Jack from University of Glasgow, said that rather than scanning evenly across a face as Westerners do, Easterners fix their attention on the eyes.

    "We show that Easterners and Westerners look at different face features to read facial expressions," Jack said. "Westerners look at the eyes and the mouth in equal measure, while Easterners favor the eyes and ignore the mouth."

    According to Jack and his colleagues, the discovery shows that communication of human emotions is more complex than previously believed. As a result, facial expressions that had been considered universally recognizable cannot be used reliably to convey emotions in cross­cultural situations.

    The researchers studied cultural differences in the recognition of facial expressions by recording the facial movements of 13 Western people and 13 Eastern people while they observed pictures of expressive faces and put them into categories: happy, sad, surprised, fearful, disgusted, or angry. They compared how accurately participants read those facial expressions using their particular eye movement strategies.

    It turned out that Easterners focused much greater attention on the eyes and made significantly more errors than Westerners did. "The cultural difference in eye movements that they show is probably a reflection of cultural difference in facial expressions," Jack said. "Our data suggests that while Westerners use the whole face to convey emotions, Easterners use the eyes more and the mouth less."

    In short, the data shows that facial expressions are not universal signals of human emotions. From here on, examining how cultural factors have diversified these basic social skills will help our understanding of human emotions. Otherwise, when it comes to communicating emotions across cultures, Easterners and Westerners will find themselves lost in translation.

    October 15^this the Global Handwashing Day. Activities are planned in more than 20 countries to get millions of people in the developing world to wash their hands with soap. For example, donors(捐赠者) will give 150,000 bars of soap to schools in Ethiopia.

    Experts say people around the world wash their hands every day, but very few use soap at so-called important moments. These include after using the toilet, after cleaning a baby and before touching food.

    Global Handwashing Day is the idea of the Public-Private Partnership for Handwashing with Soap. Partners include the United Nations Children's Fund, American government agencies, the World Bank and soap makers Unlever and Procter and Gamble. The organizers say all soaps are equally effective at removing disease-causing germ(细菌). They say the correct way to wash is to wet your hands with a small amount of water and cover them with soap. Rub(揉搓) it into all areas, including under the fingernails(指甲). Rub for at least twenty seconds. Then rinse well under running water. Finally, dry your hands with a clean cloth or wave them in the air.

    The Partnership for Handwashing says soap is important because it increases the time that people spend in washing hands. Soap also helps to break up the dirt that holds most of the germs. And it usually leaves a pleasant smell. The Partnership for Handwashing also says washing with soap before eating or after using the toilet could save more lives than any vaccine(疫苗)or medicine. Hand washing could also prevent the spread of other diseases. When people get germs on their hands, they can infect(感染)themselves by touching their eyes, noses or mouths. Then they can infect others.

The blue whale holds the current record as the largest creature to live on Earth, but a collection of bones found in Per u might break that record. Researchers have identified a whale species called Perucetus colossus in the publication Nature. Bones from this species, including backbones weighing over 100 kilograms each and ribs measuring nearly 1. 4 meters long, were found by Mario Urbina in 2012 in the Ica desert.

The area where the bones were found was once underwater, making it a rich source of ocean fossils. The find resulted in 13 backbone vertebrae(脊椎), four ribs and a hip bone. The large fossils date back to around 39 million years ago. Alberto Collareta, a lead writer of the study, described the fossils as unlike anything he had ever seen before.

The researchers used 3D scanners to study the bones' surface and also looked inside. Based on the incomplete skeleton, the team estimated that the ancient creature weighed somewhere between 85 and 340 metric tons. Comparatively, the largest blue whales found fell within that range, at around 180 metric tons. The Perucetus colossus measured about 20meters long, while blue whales can reach 30 meters in length. This means the newly discovered whale was "feasibly the heaviest animal ever," said Alberto Collareta. But he added, "it was most likely not the longest animal ever."

Interestingly, the density and weight of the Perucetus colossus' bones were much higher than those of a blue whale. This suggests that the colossal whale may have inhabited shallower coastal waters, similar to other coastal animals with heavy bones.

Another researcher, Amson, said, without the skull, it is hard to know what the whale was eating to support such a huge body. It is possible that the large creature sought food along the seafloor, the researchers said. Or it could have eaten up tons of smaller sea life in the ocean. Swiesen, a paleontologist, added that he would not be surprised "if this thing actually fed in a totally different way that we would never imagine."
