    A bite from a tsetse fly (采采蝇) is an extremely unpleasant experience. It is not like a mosquito, which can put its thin mouthpart directly into your blood, often without you noticing. In contrast, the tsetse fly's mouth has tiny saws on it that saw into your skin on its way to suck out your blood.

    To make matters worse, several species of tsetse fly can transmit diseases. One of the most dangerous is a parasite that causes ＂sleeping sickness＂, or ＂human African trypanosomiasis＂to give it its official name. Without treatment, an infection is usually fatal.

    Like so many tropical diseases, sleeping sickness has often been neglected by medical researchers. However, researchers have long endeavored to understand how it avoids our bodies' defence mechanisms. Some of their insights could now help us eliminate sleeping sickness altogether.

    There are two closely-related single-celled parasites that cause this deathly sleep: Trypanosoma brucei rhodesiense and T. b. gambiense. The latter is far more common: it is responsible for up to 95% of cases, mostly in western Africa. It takes several years to kill a person, while T. brucei rhodesiense can cause death within months. There are still other forms that infect livestock.

    After the initial bite, sleeping sickness symptoms often start with a fever, headaches and aching muscles. As the illness goes on, those infected become increasingly tired, which is where it gets its name. Personality changes, severe confusion and poor coordination can also happen.

    While medication does help, some treatments are toxic and can themselves be deadly, especially if they are given after the disease has reached the brain.

    It is worth noting that sleeping sickness is no longer as deadly as it once was. In the early 20th Century several hundred thousand people were infected each year. By the 1960s the disease was considered ＂under control＂ and had reached very low numbers, making its spread more difficult. But in the 1970s there was another major epidemic, which took 20 years to control.

    Since then, better screening programmes and earlier interventions have reduced the number of cases dramatically. In 2009 there were fewer than 10,000 cases for the first time since records began, and in 2015 this figure dropped to fewer than 3,000, according to the latest figures from the World Health Organisation. The WHO hopes the disease will be completely eliminated by 2020.

    While this decline looks positive, there may be many more cases that go unreported in rural Africa. To eliminate the disease completely, infections have to be closely monitored.

    More problematically, a series of new studies have shown that the parasite is more complicated than previously believed.

    Sleeping sickness has always been considered —— and diagnosed —— as a blood disease, because T. brucei parasites can readily be detected in the blood of its victims.

    The annual World Economic Forum (经济论坛) took place in Davos, Switzerland, in Jan. 23-26, 2018. What did Chinese entrepreneurs (企业家) speak in the forum? Are there some quotable quotes for you?

    Jack Ma, founder and executive chairman of Alibaba Group

    "I think globalization cannot be stopped — no one can stop globalization, no one can stop trade. If trade stops, the world stops. Trade is the way to dissolve (溶解，结束) the war not cause the war," said Ma in Davos, "Google, Facebook, Amazon and Alibaba — we are the luckiest companies of this century. But we have the responsibility to have a good heart, and do something good."

    Richard Liu, founder and chief executive officer of JD

    "Business is not only a way to make money but also a way to contribute yourself, to help people," Liu said in a speech in Davos. "How can we face the fractured (分化的) world? That's the topics of the Davos this year. I think a very important thing in business is cooperation. If we can unite, work together, if we work very closely, I think we can bring more hope to the people and we can build more trust between the people, countries and companies and partners," he said.

    Jane Sun, CEO of Ctrip

    "Tourism is a sunrise industry. Since I entered Ctrip, every year there are new comers, which, first of all, shows that tourism is booming." Sun told Sina.com in Davos. "We invested heavily in ABC. A refers to AI, B is big data, and C is cloud computing. As we continue to expand overseas, these three will be very good weapons for us. So we think those mean opportunity," she said.

    Hu Xiaoming, president of Aliyun

    "In 2018, people will see the development in various countries more closely connected with cloud computing. More manufacturing enterprises and financial institutions will start to use 'cloud', and cloud computing will increase the efficiency of technology and finance," Hu told Xinhua in Davos.

    The older we get, the more we learn, the better able we are to know what's right. Right? Not always. Sometimes the aging process can remove completely the natural aspects that keep us curious and give us strength to figure out what to do. As a matter of fact，children of all ages teach us lessons in our own lives.

    When a kid says“ That wasn't nice 'or' I don't like your shirt” or “I hate that kind of food!”, it's a natural reaction(反应)to shush the child not to do so, but what they say is true. When children see a wrong being done, they will interrupt to say it's not right. As adults, we usually sit nearby rather than hold a strong opinion or say something that might be unpopular.

    Kids cry, stamp( 跺) their feet or yell with excitement while it isn't socially acceptable for an adult. Letting emotions out and then moving on to deal with things, so jump and yell "yippee" when you are happy about something. Have a good cry when being upset. Stamp or throw a pillow when being alone and need to release. Most of life becomes a series of things once you reach a certain age. Finding pleasure and laughing seems out of place or silly when gaining knowledge or skills.

    “Why is the sky blue?” “ How much does an elephant weigh?” There are certain things that the Internet can tell you, but what about learning something in the first hand like the science experiment in the kitchen, digging up rocks in the backyard, how high the bicycle's wheels can fly over the gravel( 砂砾)? Don't stop exploring and find new learnings in the real world.

    Moving in with a boyfriend causes women to eat more unhealthily and put on weight. But the opposite is true for men, whose long-term health benefits when they move in with a female partner.

    Dieticians at Newcastle University said both partners try to please one another, and so change their dietary habits to suit their other half.

    It leads men to eat more light meals, such as salads, fruit and vegetables, while women choose to make creamier, heavier dishes curry or rich pasta sauces, which may please their partner. Women still have the strongest long-term influence over the couple's diet and lifestyle, as they still have the traditional role of shopper and cook in most households.

    The report, by Newcastle University's Human Nutrition Research Centre, reviewed the finding of a variety of research projects from the UK, North America and Australia, which looked at the eating and lifestyle habits of couples.

    The research shows that women are more likely to put on weight and increase their consumption of foods high in fat and sugar when they move in with their partner

    Women also use food as a comfort when dealing with emotional stress and have been found to gain weight when a relationship ends, while the same finding has not been observed in men.

    Many couples reported food as being central to their partnership, and eating together in the evening was particularly important to many.

    Report author and registered dietician Dr. Amelia Lake said, "The research has shown that your partner is a strong influence on lifestyle and people who are trying to live healthier lives should take this factor into consideration."

    It is common to see many different kinds of insects while spending time outside in the summer. Some of them do not trouble people and can even add beauty to the natural environment. Other insects can harm the environment or humans. The population of these insects seems to stay large and healthy.

    But scientists say this does not appear to be true for some flying insects that serve an important purpose. There is growing evidence that these insects are decreasing across the world.

    One researcher looking into the present insect population is Doug Tallamy, a professor at the University of Delaware. He remembers walking through Washington D. C., in the past when it was "alive with insects, especially butterflies". Now, he said, "The flying insects are actually gone." Wilson said this point seemed to be proved during a drive he made last year from Boston to Vermont. He was surprised that, during his trip, he counted only one insect that had hit the car's front window. Several other scientists have carried out similar tests by checking how many insects hit their cars while traveling.

    While researchers admit this method is not scientific, they say it can still help them understand the changing flying insect population. There have not been many studies done on the flying insect populations covering large areas. However, some international research suggests a downward turn. In 2006, a group of studies showed that there had been a 14-percent drop in ladybugs(瓢虫) in the United States and Canada from 1987 to 2006. In Germany, a 2017 study found an 82-percent drop in the number of flying insects compared to levels recorded in 1990.

    After the German study, other countries also started looking into the problem. David Wagner of the University of Connecticut says other evidence leads him to believe the findings of the 2017 study are "clearly not a German thing".
