Great white sharks! Just hearing that name makes many people's hair stand on end. In reality, these big fish have more to fear from us than we do from them. For many years, people killed countless great white sharks in the waters around the United States.

    But thanks to conservation (保护) efforts, great whites are making a comeback in the U.S. Two recent studies show that the population of these sharks is rising along the east and west coast.

    Why is the growing population of a killer fish something to celebrate? “When you fish too many of them, you start to lose balance in the environment,” says shark researcher Tobey Curtis. As the biggest killer, sharks help keep the populations of fish, seals, and other creatures they eat from growing too large.

    In spite of their importance, great white sharks had long been hunted for their meat and their fins (鳍). Then, in 1997, the U.S. government passed a law that didn't allow the hunting of great whites.

    Afterwards, the numbers of these sharks in the U.S. waters started to increase.

    The law wasn't the only thing that has helped great whites. Conservationists have also played a part in the sharks' comeback. The research group OCEARCH is using a method called tagging (加标签) to help change people's attitudes about great white. They let the public follow each shark as it travels the world's oceans. OCEARCH also gives each tagged shark a name to help people form a closer connection with the big fish.

    The group's most well-known shark is named Katharine. She was tagged last year near Cape Cod, Massachusetts. Since then, thousands of people have tracked Katharine's movements on Twitter and the OCEARCH website.

    This helps  people see sharks in a new way. Chris Fischer, the founder of OCEARCH believes learning to appreciate great whites will encourage people to do more to protect them.

    Qu Leilei: A Chinese Artist in Britain

    30 November 2017 to 15 April 2018

Contemporary Chinese artist Qu Leilei (born in 1951), now based in London, was a founding member of the creative ‘Stars Group' in the late 1970s, and immigrated to England in 1985. This exhibition shows his progression from calligraphic (书法的) art to an exploration of a new vocabulary of ink language mixing lively brushwork with western technique.

    China's cancer researcher Zhu Chen, together with two French researchers Anne Dejean and Hugues de Thé, received Sjoberg Prize 2018 in Stockholm Concert Hall, Sweden on Friday.

    “We used wisdom from both Chinese and Western medicine and offered a cure to one of the most deadly cancers,” Chen told Xinhua, “I feel that Chinese medicine has potential to contribute more to human health. It struggles for benefiting all mankind. It's a language of peace, and of development and progress.” Chen recalled the cooperation with the two French researchers for over 30 years.

    This year's Sjoberg winners have developed a new and targeted treatment for a specific form of blood cancer called acute promyelocytic leukaemia (急性早幼粒白血病). It was once one of the deadliest forms of cancer, but it is now possible to cure nine out of ten patients who receive the new treatment. The winners have made this revolutionary development possible by methodically mapping the molecular mechanisms responsible for the disease.

    The Prize is awarded by the Royal Swedish Academy of Sciences and is funded (资助)by the Sjoberg Foundation. The foundation, with a donation of 2.5 billion US dollars, was founded in 2016, and serves to promote scientific research that focuses on cancer, health and the environment.

    The Prize is an annual international prize in cancer research awarded to individual researchers or research groups. The prize amounts to one million US dollars, of which 100,000US dollars is the prize sum and 900,000US dollars is funding for future research.

    Twenty-five years ago, as a parent educator, I began reading about the dangers of praise. I was completely shocked by what I was learning: praise is not good for our kids. How could that be? So I spent years talking with experts, reading about the effects of praise, and finally decided to close the door on praise and focus on building an encouraging family.

    Even today, with many studies available to parents, I still hear people say, "How can that be? How can saying 'Good job' or 'You're smart' be bad?" I understand. It can be a difficult habit to break.

    If we tell a boy "You are so smart!" when he brings home an A in his math test, how does he feel when he comes home with a D? If we've told him that he is smart, then he will more likely feel a failure when he struggles with homework — "I'm supposed to be smart. Why can't I do this?"

    Praise trains children to depend on constant feedback on what a "great job" they are doing. This dependency shatters rather than builds children's confidence. Praise trains children to ask, "Do you like it?" "Did I do a good job?" "Are you proud of me?" They begin to believe that what others think is more important than what they think about their achievements and mistakes.

    Praise breaks the relationship between parents and children. Without even realizing it, parents may be using praise as a tool to direct the child's behavior. The message is clear — I approve of you when you … and I do not approve of you when you … Living with this kind of constant judgment can damage not only the child's confidence but also the relationship.

    The solution to the problem of praise is encouragement. Encouragement can be given at any time, to anyone, in any situation. It is a comment, an acknowledgment, a statement that focuses on effort, improvement or choice. Hearing "You are so smart!" can leave a child at a loss when they don't do well in a test. Using "That took a lot of work to come home with an A in your test …" gives a child the chance to be something else.

    I prefer Lynne Truss's phraseology: I am a grammar "sticker". And, like Truss—author of Eats, shoots & Leaves – I have a "zero tolerance" approach to grammar mistakes that make people look stupid.

    Now, Truss and I disagree on what it means to have "zero tolerance". She thinks that people who mix up basic grammar "deserve to be struck by lightning, hacked (砍) up on the spot and buried in an unmarked grave", while I just think they deserve to be passed over for a job—even if they are otherwise qualified for the position.

    Everyone who applies for a position at either of my companies, iFixit or Dozuki, takes a compulsory grammar test. If job hopefuls can't distinguish between "to" and "too", their applications go into the bin.

    Of course, we write for a living. iFixit.com is the world's largest online repair manual (指南), and Dozuki helps companies write their own technical documentation, like paperless work instructions and step-by-step user manuals. So, it makes sense that we've made a strong strike against grammar errors.

    But grammar is relevant for all companies. Yes, language is constantly changing, but that doesn't make grammar unimportant. Good grammar is credibility, especially on the Internet. And, for better or worse, people judge you if you can't tell the difference between "their" "there" and "they're".

    Good grammar makes good business sense—and not just when it comes to hiring writers. Writing isn't in the official job description of most people in our office. Still, we give our grammar test to everybody, including our salespeople, our operations staff, and our programmers.

    Grammar signifies more than just a person's ability to remember high school English. I've found that people who make fewer mistakes on a grammar test also make fewer mistakes when they are doing something completely unrelated to writing—like stocking shelves or labeling parts. It is the same with programmers. Applicants who don't think writing is important are likely to think lots of other things also aren't important.

    A typical child plays many roles, such as friend, neighbor, son or daughter. Simply reminding children of that fact can lead to better problem-solving and more flexible thinking, according to new research from Duke University.

    Better problem-solving was just one positive finding of the study, said lead author Sarah Gaither, an assistant professor of psychology and neuroscience at Duke. After thinking about their own various identities, children also showed more flexible thinking about race and other social groupings—a behavior that could be valuable in an increasingly diverse society.

    In a series of experiments, Gaither and her colleagues looked at 196 children, ages 6 and 7. In an experiment, one group of children was reminded that they had various identities, such as son, daughter, reader or helper. A second group of children was reminded of their multiple physical attributes, such as a mouth, arms and legs. All the children then needed to handle a few tasks

    Children who were reminded of their various identities showed stronger problem-solving and creative thinking skills. When shown pictures of a bear staring at honey-filled beehive(蜂窝)high up in a tree, these children had more creative ideas for how the bear might get the honey, such as turning over a bowl so that it became a stool(凳子). In other words, they saw a new use for the bowl. Children who were reminded of their multiple roles also showed more flexible thinking about social groupings. When asked to categorize different photos of faces, they suggested many ways to Spso. They identified smiling faces such as unsmiling ones, and old and young faces. The other children, meanwhile, primarily grouped people's faces by race and gender(性别).

    The-study suggests ways to promote flexible thinking for the young, which could be especially valuable for teachers." Gaither said.

    "We have this tendency in our society to only think about ourselves in connection with one important group at a time," Gaither said. "When kids think that they have various identities, they show greater abilities."
