Can people change their skin color without suffering like pop king Michael Jackson? Perhaps yes. Scientists have found the gene that determines skin color.

    The gene comes in two versions, one of which is found in 99 percent of Europeans. The other is found in 93 to 100 percent of Africans, researchers at Pennsylvania State University report in the latest issue of Science.

    Scientists have changed the color of a dark-striped zebra-fish（斑马鱼） to uniform gold by inserting a version of the pigment (色素) gene into a young fish. As with humans, zebra-fish skin color is determined by pigment cells, which contain melanin (黑色素). The number, size and darkness of melanin per pigment cell determine skin color.

    It appears that, like the golden zebra-fish, light-skinned Europeans also have a mutation (变异) in the gene for melanin production. This results in less pigmented skin.

    However, Keith Cheng, leader of the research team, points out that the mutation is different in human and zebra-fish genes.

    Humans acquired dark skin in Africa about 1.5 million years ago to protect bodies from ultra-violet rays of the sun (太阳光紫外线), which can cause skin cancer.

    But when modern humans leave Africa to live in northern latitudes, they need more sunlight on their skin to produce vitamin D. So the related gene changes, according to Cheng.

    Asians have the same version of the gene as Africans, so they probably acquired their light skin through the action of some other gene that affects skin color, said Cheng.

    The new discovery could lead to medical treatments for skin cancer. It also could lead to research into ways to change skin color without damaging it like chemical treatment did on Michael Jackson.

    The Rugby (英式橄榄球) World Cup is currently being held in New Zealand. The tournament, due to finish on October 23, is living up to the famous English saying, “Rugby is a thug's (暴徒) game played gentlemen. ”

    The games are physically aggressive; the tackles (冲撞) on the pitch are brutal; but the end of each match is a civilized affair. Players shake hands and applaud each other. Of course, the other side to this saying is: "Football is a gentleman's game played by thugs. " Indeed, unlike soccer players, rugby players don't often question the referee's (裁判员) decisions or pretend to be injured when they are not.

    “Football could learn a lot from rugby," said Brian Moore, a former England rugby player "The wonderful spirit of rugby is: there is a gentlemanly code to it. You play hard on the pitch, but you always respect your opponent..

    Rugby is mainly played in Europe. Australia, New Zealand and parts of Africa. "It is more enjoyable to play than soccer because you are always involved in the game," said Peter, a Welsh rugby coach. "Rugby is also a far superior test of strength, stamina (耐力) and determination. "

    Most professional rugby players are large, strong and weigh over 90 kilograms. People who play the sport need to be tough and be prepared to get hurt. Black eyes, broken bones, lost teeth and being knocked unconscious—all these are common injuries. Former British Prime Minister Gordon Brown is blind in one eye thanks to a rugby accident at school.

    In England, children begin playing the game at school at the age of 8. When they enter high school, many begin to play full contact rugby. Children are taught to play for around one hour a week during their PE lessons. Most schools have a rugby team. Children who play for the school team are usually the sportiest kids, and are seen as brave and athletic.

    Matthew Youlden speaks nine languages fluently and understands more than a dozen more. {#blank#}1{#/blank#} When I told Matthew how I've been working hard to only pick up a second language, he had the following advice for me.

    Know why you are doing it

    This might sound easy , but if you don't have a good reason to learn a language, you are less likely to stay interested over the long-run. {#blank#}2{#/blank#} Wanting to get to know a French person in his or her own language is another matter entirely. No matter what your reason is, once you've decided on a language, it's important to carry out .

    {#blank#}3{#/blank#}

    Matthew learned several languages together with his twin brother Michael. They learned their first foreign language, Greek, when they were only eight years old! Even if you can't get a sister or brother to join you on your language adventure, having any kind of partner will push both of you to always try just a little bit harder and stay with it.

    Have fun with it

    {#blank#}4{#/blank#}Think of some fun ways to practice your new language: make a radio play with a friend, draw a comic strip, write a poem, or simply talk to whomever you can. If you can't find a way to have fun with the new language, chances are you aren't following step four.

    Act like a child

    We learn by making mistakes. {#blank#}5{#/blank#}But as adults, mistakes become taboo(禁忌). Think how an adult is more likely to say, “I can't”, rather than, “I haven't learned that yet” (I can't swim, I can't drive, I can't speak Spanish). When it comes to learning a language, admitting that you don't know everything is the key to growth and freedom.

A. Find a partner

B. Leave your comfort place

C. We work in the same office in Berlin.

D. As kids, we are expected to make mistakes.

E. You are learning a language to be able to use it.

F. Using your new language in any way is a creative act.

G. Wanting to impress English-speakers with your French is not a very good reason.

    Chinese consumers' crazy appetite for luxury goods and services appears unstoppable,with just 2 percent of the Chinese population responsible for one-third of the world's luxury items.

    As China's economic miracle develops,the market opportunities for all sorts of luxury goods and services are increasing.Luxury consumption in China now extends ways beyond well-known car,clothing and jewelry brands.For example,the luxury jet market in China is the fastest-growing in the world,even outstripping that of the United States, with a market share of 25 percent.This trend appears to continue,with 20 to 30 percent growth expected in China, compared with only 2 to 3 percent in the US.But more importantly,China's luxury jet market growth represents a major development in the private consumption of luxury items.

    China's high-quality red wine market also provides evidence of the growth in private consumption of luxury goods.In 2013,China became the largest market for red wine in the world,even overtaking France,with l.86 billion bottles consumed in China last year.Over the past five years,China's red wine consumption has grown 136 percent.

    According to my ongoing consumer research in this area while working at the University of International Business and Economics in Beijing,public consumption of such expensive global luxury brands such as Prada and Armani is easily explained by the desire to "gain face" and publicly display social climbing through material possessions.On the other hand,it is "self-reward" that lies behind consumer motivation in this area.Chinese consumers who have experienced rapid financial and economic gains appear particularly prone to the need to reward themselves for their success.But this has little to do with "gaining face" and impressing others and much more to do with the need for personal contentment.

    Finally,the growth in private luxury consumption in China is set to continue in part due to the maturity of the Chinese consumer and advancement of Chinese consumer culture generally.

    Tablets(平板电脑) are useful devices, but their big screens always make them as a burden to carry around without a bag. Wouldn't it be great if there were a phone with the powers of a tablet that could be folded up and fit neatly into the hand? Now something like a tablet-shaped but foldable(可折叠的) phone is about to become available. In February, Samsung and Huawei both introduced foldable phones, the Galaxy Fold and Huawei Mate X separately, to the public for the first time. Mobile phone use has entered the "foldable future", the Verge noted.

    The technology could change our lives in significant ways. These devices, due to their bendable screens, give us the larger screens we want but still fit easily into the pocket. The technology could change other devices too. For example, we could make TVs that stick to walls like posters, or fold up easily to hide away in drawers, which could help increase available space to the maximum. In a keynote address, Justin Denison, Samsung's senior vice president, called the foldable screen "the basis for the smartphone of tomorrow". "It's a blank canvas (画布) for us to do something beautiful together," he said.

    So is there nothing to stand in the way of the foldable future? According to tech news website Android Authority, the necessary displays were difficult to produce. In 2012, nine out of ten foldable screens produced were defective or unusable. Today, that 10 percent rate has been improved to almost 90 percent. However, at present these foldable devices are expensive. For example, the price of Huawei Mate X is 17, 500 RMB. That's a price that few people will be able to afford.

    But if the foldable device isn't going to change the world overnight, there is no doubt that it is coming. Patrick Moorhead, an industry expert told The Verge, "Few are debating if foldable mobile displays are the future of smartphones; the only question is when and by whom."
