In the late 1950s, a Russian geneticist called Dmitry K. Belyaev attempted to create a tame (驯化的) fox population. Through the work of a breeding programme at the Institute of Cytology and Genetics at Novosibirsk, in Russia, he sought to find the evolutionary pathway of tame animals. His test subjects were silver-black foxes, a melanistic (带黑色的) version of the red fox that had been bred in farms for the color of their fur.

    He selected the animals based on how they responded when their cage was opened. About 10% of the foxes displayed a weak “wild-response”, meaning they were docile around humans. Those that hid in the corner or made aggressive voices were left in the farm. Of those friendly foxes, 100 females and 30 males were chosen as the first generations of parents.

    When the young foxes were born, the researchers hand-fed them. They also attempted to touch or pet the foxes when they were two to two-and-a-half months old, for strictly measured periods at a time. If the young foxes continued to show aggressive response, even after significant human contact, they were thrown away from the population—meaning they were made into fur coats. In each selection, less than 10% of tame individuals were used as parents of the next generation.

    By the fourth generation, the scientists started to see dramatic changes. The young foxes were beginning to behave more like dogs. They wagged their tails and “eagerly” sought contact with humans. By 2005-2006, almost all the foxes were playful, friendly and behaving like domestic dogs. The foxes could “read” human hints and respond correctly to gestures or glances.

    A car dealership in my hometown of Albuquerque was selling six to eight new cars a day. I was also told that 72 percent of this dealership's first-time visitors returned for a second visit.

    I was curious. How does a car dealership get 72 percent of its first-time visitors to return? And how can they sell six to eight cars a day in a declining car market?

    When I walked into Saturn of Albuquerque that Friday, the staff there didn't know me from Adam; yet they shared with me their pricing policy, the profit margin on every model, and staff income. They even opened their training manuals for my review and invited me back on Saturday if I wanted more information.

    On Sunday, the day after my second visit to the Saturn store, my wife, Jane, and I were walking as we frequently do. On this particular June morning, Jane gently slipped her hand in mine and said tenderly, ＂I don't know if you remember, but today's my fifth anniversary of being cancer-free.＂ I was surprised, partially because I was embarrassed that I had forgotten and, partially because.... Well, I didn't know what to do with Jane's information.

    The next day, Monday, Jane went off to work teaching school. Still not knowing what to do to mark this special occasion, I did the most impetuous thing I've ever done in my life: I bought a new Saturn. I didn't pick the color or the model, but I paid cash and told them I'd bring Jane in on Wednesday at 4:30. I told them why I was buying the car.

    On Tuesday, it dawned on me that Jane always wanted a white car. I called the sales consultant at Saturn, and I asked him if he had anything white in the store. He said he had one left but he couldn't guarantee it'd still be available on Wednesday at 4:30 because they were selling so fast. I said I'd take my chances and asked him to put it in the showroom.

    Wednesday came. Unexpectedly, someone in our family was admitted to the hospital. So, it wasn't until 9:30 Saturday morning when we finally made our way to the Saturn store. Jane had never been in a Saturn store. When we went through the front door, the Lord took control of her feet and her mouth. She saw that little white Saturn coupe all the way across the showroom floor. She quickly passed a multi-colored sea of automobiles, sat in the little white Saturn and said, ＂Oh, what a pretty little car. Can I have a new car?＂ I said, ＂No. Not until our son graduates from college.＂ She said, ＂I'm sick and tired of driving that old Dodge, I want a new car.＂ I said, ＂I promise, just three more semesters and he'll be out.＂

    Next, Jane walked around to the front of the car. As she looked it over, she let out the most blood-curdling, shrill scream I'd ever heard in 29 years of marriage.

    Now, before I tell you why Jane screamed, let me tell you what the sales consultant had done. He had ordered a large, professionally engraved sign (white letters on blue). The sign stood alone on the hood of the little white Saturn coupe. It said ＂Congratulations, Jane. This car is yours. Five years cancer-free. Let's celebrate life. From Team Saturn＂ Every employee at Saturn of Albuquerque had signed the back of that sign.

    Jane saw it, screamed, collapsed in my arms and cried loudly. I didn't know what to do. I was in tears. I took out my invoice (发票) from the previous Monday, pointing to the white coupe, said, ＂No, honey, this car isn't yours. I bought you this one.＂ I tapped the invoice with my index finger. Jane said, ＂No, I want this one right here.＂

    While this conversation was going on, there was no one in the store. The sales consultant had arranged it so that we could share the moment alone. Even so, it's impossible to have a lot of privacy when so many people are standing outside the showroom windows looking in. When Jane screamed and collapsed in my arms, I saw everybody outside applaud and begin to cry.

    Two young giant-panda twins born in the United States have returned home to China, but are straggling to adapt to the language and food.

    The 3-year-old sisters, Mei Lun and Mei Huan, wens the first surviving panda twins to be born in the United States, and were returned to China from Zoo Atlanta on Nov. 5. But the pair still understand English belter than Chinese, and prefer American biscuits to Chinese bread.

    A zoo-keeper said that his main concern is that the pair are so addicted to American biscuits that everything they eat — from bamboos to apples — has to be mixed with biscuits. They even want to snack on (零食) biscuits when drinking water.

    The zoo -keeper is trying to wean them off their biscuit habit, gradually replacing the American food with Chinese bread. Mei Huan is adapting, but Mei Lun doesn't want to touch the unfamiliar bread.

    Mei Lun is the livelier of the two, often jumping onto the roof and hanging upside down from a rail, but her slightly younger sister Mei Huan is calmer, preferring to sit still, observe her new environment and occasionally snack on bamboo.

    A language barrier is also reported. While the pair respond to their own names, and understand some English phrases such as “come here,” they don't understand the Sichuan dialect of Chinese.

    The news caused some laughter on Chinese social media, with some users commenting that the pandas would soon get used to Sichuan's famously spicy cuisine.

    My favorite book, The Secret by Rhonda Byrne, talks about a formula called "SFF" which stands for "stopping finding faults". I used to be a critical person and tried to find faults. I guess I somehow inherited this character from my father. Actually, many good qualities of my father are worth admiring except this.

    My father is the person who constantly looks for mistakes in other people and he thinks no one is perfect in the world. His character created a negative atmosphere in my family. I was the same as my father, so I often felt angry, disappointed, depressed, and lonely in school.

    After I had read my favorite book I began to seek "good things" in other people. It has completely changed my life. Now I feel happier, I have more friends, I have more trust in people, and I realize everyone has their own strength! Another important lesson I got from this book is that I should always behave myself in a positive manner. Let's admit that we sometimes complain about our situation. That's not good. "Believe it or not, people don't like to listen to negative opinions."

    One more valuable lesson I got from the book is that I should be a good listener. When I was younger, I only wanted people to pay whole attention to my words so that I could show them how important I was. I was very proud and would show off my achievements in school without considering others' feeling. I had very few friends and most people considered me as an "arrogant" person. Now, I find it much easier to make friends after making some changes!

    Why is it that many people who have suffered a major shock, such as divorce or death of a family member, seem to be weaker against a variety of major and minor illness? One common idea among psychologists has been that people could deal with suffering more effectively if they were able to understand and accept it. Indeed, many experts stress the value of expressing thoughts and feelings connected with upsetting events.

    Recently, a team of medical researchers studied the links between describing psychologically painful events and long-term health. In one experiment healthy college students were asked to write about either personally disturbing experiences or ordinary topics over a period of four days. In the months afterwards, students who had chosen to show their inner thoughts and feelings in their writing visited the health center for illness much less often than those who had written about everyday topics.

    In an experiment that followed, another group of healthy students were given the four-day writing exercises. Some chose to write about highly personal and upsetting experiences (including loneliness, problems with family and friends, and health). When questioned immediately afterwards, they said that they did not feel any better. However, their blood samples(样本) taken before and after the experiment showed evidence of an improved resistance to illness. The white cells that fight off bacteria and viruses had increased their reaction and sensitivity to these "invaders". This trend continued over the following six weeks, when another blood sample was taken. Individuals who showed the best results were those who wrote about topics that they had actively kept from telling others about.

    The researchers suggested that failure to face up to painful experience can be a form of stress itself, and can increase the possibility of illness. It follows, then, that actively dealing with a major shock makes possible its understanding and acceptance. The answer is not to suffer in silence. It may not always be possible to talk about personal problems, but writing them down will help the body to fight disease in the long run.

In 1998, people in Na Doi, a quiet village in northwest Thailand, noticed that their fish catches in the nearby Ngao River were declining. The fish they did manage to net were also getting smaller. Together, Na Doi's 75 households decided to try a new solution: they would set aside a small stretch of river to be strictly off-limits to fishing.

The rules are usually simple: no fishing of any kind in an agreed-upon area marked by flags or signs. While freshwater reserves won't solve everything, in places where fish populations are under pressure, they can give species much-needed breathing room to rebuild their numbers, ultimately making them better able to weather other environmental problems.

Na Doi was the second village in the Ngao River valley to adopt this pioneering approach to freshwater fisheries management. Since the late 1990s, at least 50 other villages there have done the same. As a whole, the entirely grassroots-led reserves have been surprisingly successful, according to findings recently published in Nature. Most importantly, the Thailand case provides probably the best real-world proof that fisheries reserves can benefit not just oceans, but freshwater, too

In 2012. Aaron Koning, then a doctoral student at the University of Wisconsin, began investigating the Ngao River valley reserves to see how widespread and successful they truly were. Koning found, not surprisingly, that older and bigger reserves were more successful, because they offered more time and space—including more kinds of habitat—in which to rebuild fish populations and re-establish rare species. But even reserves established in the last couple of years showed clear benefits from being spared intense fishing pressure. "Reserves that were located closer to a village tended to have an advantage," Koning says, "probably because villagers were better able to enforce the rules."

By comparing different systems and approaches around the world, Koning and his colleagues hope to identify common factors for success that could be tailored to diverse rivers and lakes.
