As a Chinese saying goes, "Taste is actually a memory of childhood". Local specialty food may not be popular among all people, but it offers outsiders a glimpse of local culture and history.

    Gongcheng "oil tea" is such a kind of food that would be considered "weird" by many first-time visitors to the remote county in the north of the Guangxi Zhuang Autonomous Region. Many people dislike its bitter and astringent(涩的) flavor when they take a sip.

    "It felt like drinking Chinese herbal medicine. I never expected that I would gradually accept it afterwards, and even become addicted to it," said a traveler surnamed Zhang who comes from Shijiazhuang in northern China's Hebei province.

    Langshan village is said to be the birthplace of Gongcheng "oil tea" whose ideal ingredients are green tea and fermented tea. The village has preserved well its buildings and roads dating back to late Qing Dynasty (1644-1911), as well as its traditional way of making the special tea.

    Lin Fengyou, 60, introduced the cooking process. She looks younger than her age, and attributes this to the benefits of drinking "oil tea" throughout the year.

    The first procedure is to use a wooden hammer to pound the tea while heating it in an iron pot, and then add edible oil and boiled water afterwards. She filters off the solid residues(余渣), and pours the glue-like green tea soup into bowls. Then, she adds salt, caraway seed, green onion, dried rice, fried groundnuts, sliced taro and fried beans.

    The taste of the "oil tea" is a mixture of the distinctive flavors of all its ingredients. Local people usually eat it together with glutinous rice(糯米) balls, rice dumplings and glutinous rice cake.

    The villagers consume "oil tea" three times a day. The tea soup is a healthy and refreshing food. "The tea soup to us is coffee to Westerners", said Lin. "But it is tastier."

    Teary-Eyed Stories from Strangers

    The Man at the Market

    When the supermarket clerk summed up my groceries, it was $12 over what I had on me. I began to remove items from the bags, when another shopper handed me a $20 bill. “Please don't put yourself out,” I told him.

     “Let me tell you a story,” he said. “My mother is in hospital with cancer. I visit her every day and bring her flowers. I went this morning, and she got mad at me for spending my money on more flowers. She demanded that I do something else with that money. So, here, please accept this. It is my mother's flowers.”

    A Family's Food Angel

    Since my mother lost her job, our family troubled new worries: no income, the same bills, and no way to afford groceries. It was around this time that she started finding boxes of food outside our door every morning. This went on for months, until she was able to land a job. We never did find out who it was and who left the groceries for us, but they truly saved our lives.

    Seven Miles For Me

    Leaving a store, I returned to my car only to find that I'd locked my keys and cell phone inside. A teenager riding his bike saw me kick a tire and say a few choice words. “What's wrong?” he asked.

    I explained my situation. “But even if I could call my wife,” I said, “she can't bring me her car key, since this is our only car.” He handed me his cell phone. “Call your wife and tell her I'm coming to get her key.”

    “That's seven miles round trip.”

    “Don't worry about it.”

    An hour later, he returned with the key. I offered him some money, but he refused. “Let's just say I needed the exercise,” he said. Then, like a cowboy in the movies, he rode off into the sunset.

    Breaking Bread

    Last December, before work, I stopped at a deli (熟食店) and ordered an everything bagel with cream cheese. It was toasty warm, and I couldn't wait to dig in. But as I left the store, I noticed an older indigent gentleman sitting at the bus stop. Knowing it would probably be his only warm meal of the day, I gave him the bagel.

    But all was not lost for me. Another customer from the deli offered me half of her bagel. I was so delighted because I realized that in one way or another, we are all looked after.

Learning to Run

    An article published in the scientific journal Nature discusses an important aspect of human evolution. According to Bramble and Lieberman, Professors at the University of Utah, humans possess a number of features that make them surprisingly good runners. “We are confident that the selection for running was important in the origin of the human body form,” says Bramble.

    Traditional thinking has been that humans are poor runners compared to such animals as horses. However, this is only true if we consider running at high speed, especially over short distances. Even an athlete can hardly run as quickly as a horse does, and can only keep up a top speed for 15 seconds or so. But when it comes to long-distance running, humans will do astonishingly well. They can keep a steady pace for many kilometres, and their speed is at least at the same level with that of horses.

    Bramble and Lieberman examined 26 parts of human bodies. One of the most interesting of these is the nuchal ligament (韧带). When we run, it is this ligament that prevents our head from moving back and forth or from side to side. Therefore, we are able to run with steady heads, held high. Then there are Achilles tendons at the backs of our legs, forming the mechanical links between the muscles to the bones. They act like strong strings and help to push us forward when we run. Besides, we have low, wide shoulders, a development which allows us to run more effectively. Add to this our light forearms, which swing in co-operation with the movement of our legs to assist balance, and one begins to appreciate the point that Bramble and Lieberman are trying to make.

    But what advantage is gained from being good long-distance runners? One theory is that this ability may have permitted early humans to obtain food more effectively. Some scientists guess that early humans may have run after animals for great distances to make them tired before killing them. Running would also have shown another advantage: early humans might have eaten the meat left over from a kill by other large animals. They may have been warned of the existence of a freshly killed animal by vultures (秃鹰), and the faster they got to the scene of the kill, the better.

    “Research on the history of human ability of running has traditionally been controversial,” says Lieberman. “At the very least, I hope this theory will make many people have second thoughts about how humans learned to run and why we are built the way we are.”

    A company in San Francisco, California, has found a way to turn used plastic bottles into women's shoes.

    Every day, millions of Americans drink water and other liquids from plastic bottles. More than 60 million of them are thrown away each day. Many of the plastic bottles end up in landfills or are burned with other waste products.

    A San Francisco start-up company called Rothy's, however, turns this plastic waste into environmentally friendly shoes. Rothy Martin is the company's co-founder. He explains how they turn plastic into soft material for your feet. They take the plastic, clean it, and break it down into small pieces. Then they press it through a device that makes soft fibers. Those fibers are then combined, or knit together. This is done by a three-dimensional knitting machine. It is designed to reduce waste while making the shoes.

    The knitted fabric and the inner part of the shoes are then attached to the shoes' outer part, called the sole. This outer sole is also made from environmentally friendly material: responsibly sourced no-carbon rubber.

    Rothy's shoes are sold online. They are flat shoes, with either a rounded or pointed toe. They come in different colors and designs. They cost either $125 or $145 per pair, depending on the design.

    After American actress Gwyneth Paltrow discovered them last year, the demand for the shoes grew.

    Martin says there is no shortage of material to fill that demand. “We're not going to run out of water bottles any time soon. So we have an infinite supply of material, and I think that bodes well for our future. ”

    When the environmentally friendly shoes wear out, customers can return them at no cost to a company that uses the recycled materials to make other products.

    For now, the shoes are only available to be shipped in the United States. However, the company says it will add international shipping in the near future.

    People from all over the world visit Disneyland to have fun, not to get sick. But last week, an outbreak of measles(麻疹)spread from the Southern California theme park. As of Monday, January 19, at least 52 people have got the easily spread illness.

    The majority of the reported cases of measles are from people who visited the park before. According to the California Department of Public Health, these people were exposed to the illness at Disneyland from December 17-20.

    Officials believe the cause is likely someone who caught measles abroad and visited Disneyland, but this has yet to be proved. However, in 2014, California had its highest measles infection rate in nearly twenty years. There were 66 cases of measles reported in the state―23 of them in Orange County, where Disneyland is located.

    Measles spreads very easily. It can be caught from coughing and sneezing. Crowded areas like theme parks are especially suitable for its spread.

    The illness starts with a fever and develops into symptoms including a cough, runny nose, red eyes and so on. About three out of ten people infected with measles will develop another health problem, including an ear infection or pneumonia(肺炎).

    The best way to guard against measles is to get vaccinated(打疫苗). An unvaccinated person is 35 times more likely to catch measles than someone who received a vaccination.

Every year, thousands of teenagers participate in programs at their local art museums. But do any of them remember their time at museum events later in life? A new report suggests that the answer is yes--and finds that arts-based museum programs are credited with changing the course of alumni's（毕业生的） lives, even years after the fact. 

The Whitney Museum of American Art, the Walker Art Center and the Museum of Contemporary Art, Los Angeles recently asked researchers to conduct à study to find out how effective their long-standing teen art programs really are. They involved over 300 former participants of four programs for teens that have been in existence since the 1990s. Alumni, whose current ages range from 18 to 36, were invited to find out how they viewed their participation years after the fact. 

Among the alumni surveyed, 75 percent of them thought the teen art program experience had the most favorable impact on their own lives, beating the family, school and their neighborhoods. Nearly 55 percent thought that it was one of the most important experiences they had ever had, regardless of age. And two-thirds said that they were often in situations where their experience in museums affected their actions or thoughts. 

It turns out that participating in art programs also helps keep teens keen about culture even after they reach adulthood: Ninety-six percent of participants had visited an art museum within the last two years, and 68 percent had visited an art museum five or more times within the last two years. Thirty-two percent of alumni work in the arts as adults. 

Though the study is the first of its kind to explore the impact of teen-specific art programs in museums, it reflects other research on the important benefits of engaging with the arts. A decade of surveys by the National Endowment for the Arts found that the childhood experience with the arts is significantly associated with people's income and educational achievements as adults. Other studies have linked arts education to everything from lower dropout rates to improvement in critical thinking skills.
