The Children's Book-Show Competition is a chance for young readers to be writers.

    Reading, it seems, is coming back in fashion, if a survey by the famous National Literacy Trust (the NLT) is true. It shows that the percentage of children who admit enjoying reading has grown for the first time in the past 8 years.

    So it's a good time to launch a competition that includes a shed-load of new books for schools as prizes. The Children's Book-show Competition, backed by The Independent, is taking to the roads again from the start of next term, with a nation-wide tour of 15 big cities, featuring a line-up of a dozen children's writers and illustrators (插图画家) aiming to persuade pupils to follow their footsteps.

    The competition, launched by the children's writer and illustrator Jessica Souhami, has two categories: the under-nine's and nine to 13-year-olds.

    Children are asked to choose their favorite fairy or folk tale and set it in an extraordinary place.

    Then they are to retell it with the aid of drawings and writings—whether it is set at sea, on a distant planet, in the future or in the past. The closing date for the competition is 30th November.

    “Tell your tale in pictures and in words, ”say the organizers of the competition. “It can be in a picture book or comic-book format.”

    The winner of each competition will receive a signed copy of a book by each of the 12 authors involved in this year's tour, plus £150 worth of books for their school. The runners-up will receive a signed copy of Souhami's new book.

    A man came home from work late, tired, to find his 5-year-old son waiting for him at the door.

    “Daddy, how much money do you make each hour?”

    “If you must know, I make ＄20 each hour.”

    “Oh,” the little boy answered, with his head down. He thought for a moment, looked up and said, “Daddy, could you lend me ＄10?”

    The father was furious, “If you asked for the money to buy a toy or some other rubbish, go straight to your room and think about why you are so selfish (自私)！”

    The little boy went to his room with no words and shut the door. After a short while, the father calmed (平静) down, and started to think, “Maybe he really needs to buy something and he didn't really ask for money very often.” So he went to the little boy's room.

    “Sorry！Maybe I was too hard on your just now.” said the man, “Here's ＄10.”

    “Oh, thank you Daddy！” he said happily. Then the boy took out some coins. When the father found that the boy already had money, he got angry again.

    “Why do you want more money since you already have some?” the father shouted angrily.

    “Because I didn't have enough, but now I do.” The little boy replied, “Daddy, I have ＄20 now. Can I buy one hour of your time? Please come home early tomorrow. I would like to have dinner with you. ”

    My two- and four-year-old boys love to win, whether they're racing their bikes down the sidewalk or just finishing their snacks. It's true that those with high status, from world leaders and prize winners to athletes and movie stars, are people we like and respect. A recent study published in Nature Human Behaviour showed that we seem to have an innate (天生的) preference for high-ranking peoples—but only if those people aren't hurtful toward others.

    Researchers showed toddlers (aged 21 to 31 months) a scene where two puppets (木偶) approached one another from opposite sides of a stage and one bowed to let the other pass first. Asked which puppet they liked better, 18 of the 21 toddlers in the experiment reached for the puppet who had been allowed to pass. Because respect from others is a marker of status, this suggests that children have a preference for those with a higher status—even before age three.

    However, the results were quite different when two puppets approached one another and one used force to knock the other down before continuing to the other side. In this case, 18 of the 21 toddlers reached for the one who was knocked down. As the researchers concluded, "When approaching others, very young children care not only who wins, but also how." The previous experiment has shown that toddlers know about social status, but this experiment went one step further by proving they have an obvious preference for high status. Since the participants were so young, this might even be an innate human preference.

    In a word, this new research suggests that young children appreciate people who do well while at the same time doing good to others. So, when my four-year-old thinks that he has to get his shoes on first, I'll keep reminding him that helping his brother so they both finish faster is what winning is all about.

For eight-year-old Toby, who is deaf, watching films or TV can sometimes be a bit pointless, because so many of them don't have sign language versions. "We have subtitles but it goes too fast," his dad Jarod Mills said. But now, Toby has some help thanks to an app developed by a 17-year-old student, Mariella Satow, who created a signing app called SignUp.

She got the idea when she was teaching herself American Sign Language(ASL)—one of hundreds of sign languages used across the world. Manella wanted to watch TV shows to help her learn, and she was disappointed to discover how few had signed versions. It's taken a year for Mariella to develop the technology, with lots of help from ASL teachers and the deaf community.

The app is available in the US as a browser extension—with an interpreter appearing in a box once the film starts playing. It only works on Disney Plus films at the moment, because that's where Mariella thought she could help the most children. Jarod, who works at a school for deaf children, says it was "exciting" watching Toby use Mariella's invention. He says, "Kids are getting information like any hearing child does."

Deaf people in the UK face many of the same barriers when it comes to cinema and TV. "A hearing person can go to the cinema any time whereas deaf people have to make sure there's a suitable viewing a time we're free," says 27-year-old Stacey Worboys from Cardiff. She has learned British Sign Language(BSL), and is comfortable using subtitles when watching TV shows and films. But she feels having an interpreter would make things "more inclusive", especially for someone who might struggle with subtitles. Stacey and Toby aren't the only people to be welcoming Mariella's app. It's now got thousands of users.

Stacey says a UK version of an app like SignUp would make films and TV "more accessible" for the deaf community. Mariella is up for the challenge—and hopes to make a British Sign Language version of her app for other streaming platforms such as Netflix and Amazon Prime. "There are more than 300 sign languages used worldwide, so it'll take a long time to get all of those versions out," she says.

Some people often wonder whether they are fighting a battle with their genes to maintain a healthy weight. In fact, researchers have provided plenty of evidence that people are born with tendencies to be lighter or heavier. For example, studies of identical twins have revealed great similarity in their overall weight. Part of this similarity may be explained by the finding that some people are born to burn a lot of calories just through ordinary day-to-day activities while others are not. Those who are not are more at risk for weight gain.

Researchers have discovered some of the actual genetic mechanisms (机制) that may make some individuals more likely to be obese. For example, a gene has been found that appears to control signals to the brain that enough fat has been stored in the body in the course of a meal—so the individual should stop eating. The gene influences the production of leptin (瘦蛋白), which keeps appetite under control. If leptin doesn't work well, it is likely that individuals will continue to eat. Thus the gene that controls leptin appears to have a critical influence on the potential for obesity.

The confirmation that leptin plays a role in weight control has encouraged researchers to identify and understand other weight-related genes. Recent attention has focused on a gene called GAD2. GAD2 helps control the amount of the neurotransmitter (神经递质) GABA. In general, when more GABA is available, appetite is increased. For that reason, people who have a form of GAD2 that allows more GABA to be available may be at risk for overeating. You can see that GAD2 is not directly an obesity gene. Rather it has an indirect influence on obesity through its direct influence on GABA.

Genetic research holds out the promise of innovative solutions to obesity. Researchers hope that an understanding of the link between genus and weight control will enable them to provide new drug treatments. Nonetheless, even the most optimistic researchers provide a warning: "Innovative drugs will be effective only when they are used along with lifestyle changes."
