    China became the first country to clone a monkey using non-reproductive cells, scientists said on Thursday. By December 2017 , the Chinese Academy of Sciences had created two clone macaques(猕猴) named“Zhong Zhong” and “Hua Hua”by nuclear transferring of body cells—any cell in the organism other than reproductive cells. This was the similar technology used to create the famous clone sheep Dolly in 1996.

    Telra, a monkey born in 1999 , is the world's first ever-cloned monkey, but it was done using a simpler method called embryo splitting(胚胎分裂)，and cannot be genetically modified to suit experimental needs, said Pu Muming, a leading researcher at the Chinese Academy of Sciences. Cloning a monkey using body cells has been a world-class challenge because it is a primate(灵长类)that shares its genetic makeup, therefore all of its complexity, with humans, he said.

    For drug and other lab tests, scientists have to purchase monkeys from all over the world, which is costly, bad for the environment and produces inaccurate results because each monkey might have different genes, Pu said.

    By cloning monkey using body cells, we can mass reproduce a large number of genetically identical monkeys in a short amount of time, and we can even change their genes to suit our needs, he added. “This can save time, cut down experiment costs, and produce more accurate results, leading to more effective medicine.”

    Sun Qiang, director of the non-human primate research facility at the institute, said most of the drug trials are currently done on lab mice. However, drugs that work on mice might not work or even have severe side effects on humans because the two species are so different.

    Monkeys and humans are both primates, so they are much closely related and testing on monkeys is supposed to be as effective as testing on humans. This achievement will help China lead the world research in an international science project related to study of primate brains.

    In 2006, a New York City English teacher named Ms Lockwood asked her students to write to their favorite authors and persuade them to visit the school. Five of those pupils chose novelist Kurt Vonnegut who was the author of 14 novels. He was the only author to reply. Though he never made the trip to their school, Vonnegut responded to the students with the following letter.

    Dear Xavier High School, Billy, Sally, Jonny, Maurer and Kathy,

    I thank you for your friendly letters. You sure know how to cheer up an old man (84) in his sunset years. I don't make public appearances anymore. I'd like to advise you to do the following things: Practice any art—music, singing, dancing, acting, drawing, painting, poetry, fiction, essays—no matter how well or badly, not to get money and fame, but to experience becoming, to find out what's inside you, to make your soul grow.

    Seriously! I mean starting right now, do art and do it for the rest of your lives. Draw a funny or nice picture of Ms Lockwood and give it to her. Dance home after school, and sing in the shower, and on and on. Pretend that you're Count Dracula. Here's an assignment for tonight, and I hope Ms Lockwood will not let you pass the test if you don't do it.

    Write a six-line poem about anything. Make it good as you possibly can. But don't tell anybody what you're doing. Don't show it or recite it to anybody, not even your girlfriend or parents, or Ms Lockwood. OK? Tear it up into pieces and throw them into dustbins. You will find that you have already been gloriously rewarded for your poem. You have experienced becoming, learnt a lot more about what's inside you, and you have made your soul grow.

      God bless you all.

                                                                                                                                                                          Kurt Vonnegut

    March 21 has been declared World Sleep Day, a time to recognize and celebrate the value of sleep. Many sleep experts hope it will be a wake-up call.

    According to a 2016 poll（民意调查）by the National Sleep Foundation, nearly 4 in 5 Americans don't get as much sleep as they should during the workweek. On average, adults are thought to need at least eight hours of sleep a night, although some can manage with less and some won't do well without more. But the survey found that, on workdays, only 21% of Americans actually get a full eight hours of sleep, and another 21% get less than six.

    To many of us, the thought of spending more time sleeping is, well, a big yawn. On the other hand, the thought of being smarter, thinner, healthier and more cheerful has a certain appeal. And those are just a few of the advantages that can be ours if we consistently get enough sleep,  researchers say. Also on the plus side： We're likely to have better skin, better memories, better judgment, and, oh, yes, longer lives.

    "When you lose even one hour of sleep for any reason, it influences your performance the next day, " says Dr. Alon Avidan, director of the UCLA Sleep Disorders Center.

    A study published last year found the same to be true even of children.  When kids aged 8 to 12 slept for just one hour less for four nights, they didn't function as well during the day.

    But sleeping has an image problem. "We see napping or sleeping as lazy, " says Jennifer Vriend, a clinical psychologist in Ottawa, Canada, and the leading author of the study with children. "We put so much emphasis on diet, nutrition and exercise. Sleep is in the back seat. " In fact, she adds, no matter how much we work out, no matter how well we eat, we can't be in top physical shape unless we also get plenty of sleep.

    Jon Hoffman was sitting at a red light when he saw a man run out of a store carrying a plastic donation jar full of cash. The Plano, Texas, detective, dressed in plain clothes but wearing his badge (徽章) and gun, caught the man and pinned him to the hood of his car. But Hoffman had trouble containing the thief, and they got into a struggle.

    "The detective has a martial arts background, and he said he thought the suspect must have a martial arts background, too, because he was able to break away so easily," a Plano police spokesperson said.

    The detective called out for help as a crowd gathered. Among those watching: Andre Harvey and Kirby Sample, two day laborers. Harvey did what has become common these days—he took out his phone and hit record. "I hate to say it, but I thought that this policeman was doing something illegal," Harvey said. "But when he asked for help, I thought, well, there won't be a shooting if I get over there in time.” Harvey jumped into action—while he was still recording the video—as did Sample.

    "Harvey caught hold of the suspect's arms, while Kirby seized his legs, and they were able to get the suspect to the ground to help Detective Hoffman put the handcuffs (手铐) on," said the police spokesperson. The 27-year-old suspect was charged with resisting arrest and other offenses. The charity jar he stole held less than $ 50.

    "I've been on the wrong side of the law several times in my life," Harvey told WFAA. "It feels good to be on the right side and do something positive."

    After the arrest, the three men got to know each other over steaks and ribs at a local steak house—Hoffman's treat, as a thank-you. But the rescuers say Hoffman deserves credit too. "It could have turned real ugly." Sample told the media "He handled himself like a real professional."

    If English means endless new words, difficult grammar and sometimes strange pronunciation, you are wrong. Haven't you noticed that you have become smarter since you started to learn a language?

    According to a new study by a British university, learning a second language can lead to an increase in your brain power. Researchers found that learning other languages changes grey matter. This is the area of the brain which processes information. It is similar to the way that exercise builds muscles.

    The study also found the effect is greater when the younger people learn a second language. A team led by Dr. Andrea Mechelli, from University College London, took a group of Britons who only spoke English. They were compared with a group of "early bilinguals" who had learnt a second language before the age of five, as well as a number of later learners.

    Scans showed that grey matter density (密度) in the brain was greater in bilinguals than in people without a second language. But the longer a person waited before mastering a new language, the smaller the difference.

    "Our findings suggest that the structure of the brain is changed by the experience of learning a second language," said the scientists.

    It means that the change itself increases the ability to learn.

    Professor Dylan Vaughan Jones of the University of Wales, has researched the link between bilingualism and maths skills. "Having two languages gives you two windows on the world and makes the brain more flexible (灵活的)," he said. "You are actually going beyond language and have a better understanding of different ideas."

    The findings were matched in a study of native Italian speakers who had learned English as a second language between the ages of two and thirty-four. Reading, writing, and comprehension were all tested. The results showed that the younger they started to learn, the better. "Studying a language means you get an entrance to another world," explained the scientists.
