The TV shows like “Children are hard tosupport!”, “Where are we going, Dad?”, “hot mom” and “cute kids” are becomingmore and more popular. All of these show the new parents' confusion inchildren's education and the appeal for the balance between career and family.

In real life, on the one hand, the youngparents feel helpless because they are too busy to accompany their childrenunder the pressures of work and life; on the other hand, they continue to doso. The data collected by HNTV show that nearly two-thirds of their audienceare female, among whom 36% are aged from 25 to 34. We can imagine such a scenethat one evening a young mother is watching the show with her young children,while her husband is still at work or trapped in socializing, or maybe is justplaying computer games in the bedroom. The story of a child without the companyof father is still going on. In fact, it is sometimes the same to mothers. In amodern family, it is often the old who take the responsibility for raising achild. The participation of mother in the children's education is also verylow.

    It is just this kind of confusion wherethe parents have gone in the modern family education, and where the parentswill guide their children to go that “Where are we going, Dad?” shows us. If achild wants to grow up healthily and safely into a modern citizen withindependent personality and free spirit, it is very important for him or her tofollow the parents who serve as their first teacher. Maybe this is the realreason why such kind of TV programs could get hot. The truth is that childrenwill go where their parents go, and society will go where the children go.

    Jayson McCarthy, 12, was born without fingers on his left hand. That didn't stop him from being able to do many tasks. But Jayson could not grasp more than one object at a time. So Jayson 's father, Paul, created a Prosthesis(假肢), using a 3D printer. Now Jayson has fingers that open and close. “It was a do－it－yourself, father－and－son adventure，” says Paul.

    When Jayson was a baby, his doctor advised his parents not to give him a prosthetic hand until he was in his early teens. “The doctor said Jayson should first learn to get full use out of the hand he was born with，” says Paul. As Jayson got older, his father looked into purchasing a prosthetic hand, which can cost as much as $30，000. Paul found a more affordable solution.

    One day, Paul discovered a video on the Internet about Robohand, a prosthesis created with a 3D printer. He downloaded the free instructions and called Robohand's creators for advice. They told him all he needed was a 3D printer—which costs around $2，000—and some materials.

    Luckily, Jayson 's school had recently purchased a 3D printer and it offered to help Paul build the hand for Jayson n. “We used a soccer shinguard(护胫), cardboard(硬纸板), and tape. They cost about $10，” says paul.

    With his new hand, Jayson can do things better. “I can help my mom more, because now I can carry two grocery bags，” he says.

    Jayson 's father has already built several hands for Jayson. Jayson helps design each one. He says there's one thing in particular that he wants to do with a future prosthesis. “The goal，” he says, “is to be able to tie my shoelaces(鞋带)．”

    Life is full of funny moments, and not just for humans.

    Over the years, studies by various groups have suggested that monkeys, dogs and even rats love a good laugh. People, meanwhile, have been laughing since before they could talk.

    Jaak Panksepp, a professor at Bowling Green State University, US, said he would not be surprised if positive feelings could be produced in some animals. Dolphins, for example, have long attracted animal researchers because of the complex (复杂的) ways in which they communicate: a rich variety of sounds of different rhythms. A decade ago, researchers studying dolphins at the Kolmarden Wildlife Park in Sweden noticed a set of sounds the dolphins made during play-fighting. They concluded that the purpose of the sound was to suggest that the situation was pleasant and to prevent it from a real fight.

    Panksepp has even seen evidence of joy in crayfish (小龙虾). When given small amounts of drugs such as cocaine (可卡因) in a certain place, they appear to connect that location with pleasure. “Given the chance, they will always return to that place, perhaps in the hope of getting more,” he says. Panksepp wasn't sure it equals the same happiness that humans get from cocaine, but said it “could be in the same evolutionary category”.

    More studies are needed to really understand animals' laughter. Strangely enough, the answers may help with our own desires for cures for mental illnesses. Panksepp's experiments may soon lead to a new antidepressant (抗抑郁) drug that works by using the pathways in the brain behind positive feelings and joy. Perhaps pleasure and laughter in the animal world will help solve the depression in our own species one day.

    Next time a customer comes to your office, offer him a cup of coffee. And when you're doing your holiday shopping online, make sure you're holding a large glass of iced tea. The physical sensation (感觉) of warmth encourages emotional (情感的) warmth, while a cold drink in hand prevents you from making unwise decisions—those are the practical lesson being drawn from recent research by psychologist (心理学家) John A. Bargh.

    Psychologists have known that one person's perception (感知) of another's “warmth” is a powerful determiner in social relationships. Judging someone to be either “warm” or “cold” is a primary consideration, even trumping evidence that a “cold” person may be more capable (能干的). Much of this is rooted in very early childhood experiences, Bargh argues, when babies' sense of the world around them is shaped by physical sensations, particularly warmth and coldness.

    Feelings of “warmth” and “coldness” in social judgments appear to be universal. Although no worldwide study has been done, Bargh says that describing people as “warm” or “cold” is common to many cultures, and studies have found those perceptions influence judgment in dozens of countries.

    To test the relationship between physical and psychological warmth, Bargh conducted an experiment which involved 41 college students. A research assistant who was unaware of the study's hypotheses (假设), handed the students either a hot cup of coffee, or a cold drink, to hold while the researcher filled out a short information form: The drink was then handed back. After that, the students were asked to rate the personality of “Person A” based on a particular description. Those who had briefly held the warm drink regarded Person A as warmer than those who had held the iced drink.

    “We are grounded in our physical experiences even when we think abstractly (抽象的),” says Bargh.

    A British friend told me he couldn't understand why Chinese people love eating sunflower seeds as a snack so much. “I've met a lot of older Chinese and many have a crack in their front teeth; I believe that's from cracking the seeds, ” he said.

    I had never noticed the habit, but once he mentioned it, I suddenly became more aware. I realized that whenever I'm watching TV or typing a report, I always start mindlessly cracking sunflower seeds. My friend doesn't like sunflower seeds, and, to him, it seems unnecessary to work so much just to get one small seed.

    When we were young, the whole family would usually get together for Chinese New Year. Then, we all lived close to one another, usually in a small city, and sometimes even neighbors would go door-to-door on Chinese New Year's Eve to check out what every household was making.

    I remember my parents would be in the kitchen cooking. Out in the living room , a large table would already be laid out, complete with fancy tablecloth, ready-made dumpling fillings, and dishes full of candy, fruits and sunflower seeds. Some of the dishes were to be offered to our ancestors later, while others were for neighbors and children to eat before the evening feast. I must have learned how to crack sunflower seeds back then.

    I don't think it's right to criticize one's choice in food or eating habits, no matter how strange they may seem.

    It's not only in China. When I went abroad, I found people had all sorts of strange habits when it came to food. In Denmark, they put salted red fish on bread and eat it for dinner, no matter how much it ruins your breath. They think it's a delicacy, and it's connected to their culture. I think it's a wonderful tradition.

The World's Unusual Libraries

    Log Libraries

    Alex Johnson writes in his new book—Improbable Libraries,“ The very idea of a library is developing: many of these libraries operate on principles that differ mainly from the traditional libraries. Some, for example, have no membership or identification requirements, and some do not even request that the books be returned.” The oversized bird box in a park in Lowa is part of the Little Free Library Movement, which was established in Wisconsin in 2009.

Phone Booths

    This design from the firm, Stereotank, offers browsing shelter for passers-by. In the UK, a phone company's programme, allowing communities to take over their phone booth for £ 1— means that many have been changed into tiny local libraries. Meanwhile, a solar light has been set in a phone booth so that late night visitors can still read.

    Branches of Knowledge

    Didier Muller's libraries operate as hanging libraries: visitors can look through pages, taking any book they choose and exchanging it with their own. The equipment of hanging wooden houses is one of several art projects serving as a booklover's place.

    Soundproofed Pods

    Around the world, architects are designing buildings that bend bricks-and-mortar libraries into new forms. The Seikei University Library in Japan—the vision of Pritzker Prize winner Shigeru Ban—contains space-age soundproofed (隔音的) pods to encourage discussions between students.
