Recordings of angry bees are enough to send big, tough African elephants running away, a new study says. Beehives (蜂窝)—either recorded or real—may even prevent elephants from damaging farmer's crops.

    In 2002, scientist Lucy King and her team found that elephants avoid certain trees with bees living in them. Today, Lucy wants to see if African honeybees might discourage elephants from eating crops. But before she asked farmer to go to the trouble of setting up beehives on their farms, she needed to find out if the bees would scare elephants away.

    Lucy found a wild beehive inside a tree in northern Kenya and set up a recorder. Then she threw a stone into the beehive, which burst into life. Lucy and her assistant hid in their car until the angry bees had calmed down. Next，Lucy searched out elephant families in Samburu National Reserve in northern Kenya and put a speaker in a tree close to each family.

    From a distance, Lucy switched on the pre-recorded sound of angry bees while at the same time recording the elephants with a video camera. Half the elephant groups left the area within ten seconds. Out of a total of 17 groups, only one group ignored the sound of the angry bees. Lucy reported that all the young elephants immediately ran to their mothers to hide under them. When Lucy played the sound of a waterfall (瀑布) instead of the angry bees to many of the same elephant families, the animals were undisturbed. Even after four minutes, most of the groups stayed in one place.

Lucy is now studying whether the elephants will continue to avoid the sound of angry bees after hearing it several times. She hasn't tested enough groups yet to know, but her initial (最初的) results were promising enough to begin trials with farmers. She has now begun placing speakers in the fields to see if elephants are frightened away.

    Another thing an astronaut has to learn about is eating in space．Food is weightless, just as men are.

    Food for space has to be packed in special ways．Some of it goes into tubes that a man can squeeze into his mouth．Bite-sized cookies are packed in plastic.

    There is a good reason for covering each bite．The plastic keeps pieces of food from traveling in the spaceship．On the earth very small pieces of food would simply fall to the floor．But gravity doesn't pull them to the floor when they are out of the plastic in a spaceship．They move here and there and can get into a man's eyes or into the spaceship's instruments．If any of the instruments is blocked, the astronauts may have trouble getting safely home.

    As astronauts travel on longer space trips, they must take time to sleep．An astronaut can fit himself to his seat with a kind of seat belt. Or, if he wants to, he can sleep in a sleeping bag which is fixed in place under his seat．But be careful he must put his hands under the belt when he goes to sleep．This is because he is really afraid that he might touch one of controls that isn't supposed to be touched until later.

    Nearly 19 percent of teachers of color (有色人种教师) left their jobs after the 2014-2015 school year. Some left for personal reasons like taking care of their families. But 50 percent said they left because they were dissatisfied with their employment situation, such as poor working conditions, student discipline problems and large class sizes. Thus, taking immediate measures to improve it is our top priority.

    For years, researchers have proved the benefits of increasing the share of minority teachers in schools, especially as our public school system has turned to one that is made up mostly of minority students. Teachers of color, who are more likely than their white counterparts to choose to work in racially diverse (多种多样的) schools, offer particular benefits to their students. Graduation rates increase among minority students when they are taught by racially similar educators, research shows. They can also serve as positive role models, and their presence reduces the chance of racial discrimination at school.

    The Shanker Institute report suggests that the rate of minority teacher hiring is not the whole problem. The problem is what happens after these teachers enter the classroom. These teachers often work in high-poverty rural schools. They are more likely to have less-desirable working conditions.

    Diversity is a key component to equality and opportunity. Where there's a diverse teaching workforce, all kids thrive. So solutions must be found at once to turn this trend around. Firstly, schools should develop mentorship programs that support minority teachers once they are in the classroom. Secondly, more money should be spent in improving working conditions in these schools. Of course, school headmasters should also be evaluated on their ability to retain teachers of color.

    We started in 1993 with a simple idea: that people could help each other by sharing stories about their lives. For years people had told our founders, motivational speakers Jack and Mark, inspiring stories about themselves. Jack and Mark included these stories in their talks, and their audiences repeatedly asked if they had ever been published.” That story about the boy and the puppy—is that in a book anywhere?” a parent asked Jack. “That story about the boy with the amputated(截肢)leg who became a tennis star, I need to read that to my staff,” a manager told him. Jack was asked repeatedly, “ Is that story in a book anywhere?”

    Eventually Jack and Mark decided their audiences must be on to something, so they collected the best 101 stories they'd been told in a book. They called it Chicken Soup for the Soul because they wanted it to provide comfort just like their grandmother's cooking.

    They took the book to New York, hoping to sell it to one of the big publishers but every single one turned them down. The project appeared to have stalled until they met Peter Vegso, the owner of a small health and wellness polisher in Florida named HCI. Peter read some of the stories and loved them, so he decided to give the book a chance, becoming Chicken Soup for the Soul's founding publisher.

    Never, in Jack and Mark's wildest dreams had they imagined what the book would become. Chicken Soup for the Soul turned into one of the most popular and loved books ever published, selling 11 million copies around the world. Readers asked for more stories so we published a “second helping” of Chicken Soup for the Soul and a third after that, Today, we've published more than 250 books, which have become the best-selling trade paperback book series of all time.

    Clothes can make phone calls, play music, dial your pal's number, keep you warm during cold weather and operate your computer?

    This is not a fantasy. A British company, called Electrotextiles, has created a wide range of clothes—clothes that have minds of their own! Scientists, working for the company, have invented a kind of cloth that can be mixed with flexible (有弹性的) electronic materials to create intelligent clothing. The results are electronic garments (衣服).

    If you think the wearer has to be wired to different devices, think again. These designer clothes are wire-free, soft to touch and washable! Like any electronic device, these high-tech clothes have to be powered. Currently, a tiny nine-volt battery serves the purpose. But the researchers hope that in the near future the clothes will produce electricity by using body heat. These clothes are 100 percent shock proof, they say.

    The Electrotextiles team has also created the world's first cloth keyboard. This keyboard can be sewn into your trousers or skirt. To use this device, you will have to sit down and tap on your lap! These 'lap-tap' gadgets (器具), are all set to take over laptop computers!

    Another useful garment is the shirt-cum-mobile phone. This handy invention enables drivers to chat comfortably with others at the wheel! Other popular electronic wear include the denim (牛仔布) jacket with flexible earphones sewn into the hood and the electronic ski jacket with a built-in heater. The ski jacket is also programmed to send signals to a satellite. This technology is known as global positioning system and can be used to track lost skiers and wandering kids.

    Having completed the cloth keyboard, scientists have already started to work on a new project—a necktie that can be used as a computer mouse. What is the next? Do you have any idea?
