Disposing(处理) of waste has been a problem since humans started producing it. As more and more people choose to live close together in cities, the waste-disposal problem becomes increasingly difficult.

    During the eighteenth century, it was usual for several neighboring towns to get together to select a faraway spot as a dumpsite. Residents or trash haulers(垃圾托运者) would transport household rubbish, rotted wood, and old possessions to the site. Periodically(定期的) some of the trash was burned and the rest was buried. The unpleasant sights and smells caused no problem because nobody lived close by.

    Factories, mills, and other industrial sites also had waste to be disposed of. Those located on rivers often just dumped the unwanted remains into the water. Others built huge burners with chimneys to deal with the problem.

    Several facts make these choices unacceptable to modern society. The first problem is space. Dumps, which are now called landfills, are most needed in heavily populated areas. Such areas rarely have empty land suitable for this purpose. Property is either too expensive or too close to residential(住宅区的)neighborhoods. Long-distance trash hauling has been a common practice, but once farm areas are refusing to accept rubbish from elsewhere, cheap land within trucking distance of major city areas is almost nonexistent.

    Awareness of pollution dangers has resulted in more strict rules of waste disposal. Pollution of rivers, ground water, land and air is a price people can no longer pay to get rid of waste. The amount of waste, however, continues to grow.

    Recycling efforts have become commonplace, and many towns require their people to take part. Even the most efficient recycling programs, however, can hope to deal with only about 50 percent of a city's reusable waste.

    When I was in my fourth year of teaching, I was also (and am still) a high school track and field coach (田径教练). One year, I had a student, John, who entered my class when he was a junior.

    When I was in my fourth year of teaching, I was also (and am still) a high school track and field coach (田径教练). One year, I had a student, John, who entered my class when he was a junior. John changed to our school from Greece, and seemed to be interested in athletics, so I encouraged him to join our track team. I explained to him that even though he had never taken part in it before, I did believe that he could do well in any event, and I would be willing to coach him at whichever ones interested him. He accepted the offer, and began to work hard at every practice.

    About a month later, I had found out from other sources that John was a first-class tennis player, winning various junior awards in his home country. I went to him asking, “John, I really appreciate that you came out for the track team, but why didn't you play tennis instead? It seems that would interest you a lot more, since you're so good at it.” John answered, “Well, I like tennis, but you told me that you believed in me, and that you thought I could do well in track, so I wanted to try it for that reason.”

    From then on, I often remember my student's reply. I told it to a friend and she suggested I write it down to share somewhere with more teachers. No matter how critical (不满的) students can be of themselves, I've found that a simple “I trust that you can do it!” can go a long way!

    Norman Garmezy, a development psychologist at the University of Minnesota, met thousands of children in his four decades of research. A nine-year-old boy in particular stuck with him. He has an alcoholic mother and an absent father. But each day he would walk in to school with a smile on his face. He wanted to make sure that "no one would feel pity for him and no one would know his mother's incompetence." The boy exhibited a quality Garmezy identified as "resilience".

    Resilience presents a challenge for psychologists. People who are lucky enough to never experience any sort of adversity (逆境) won't know how resilient they are. It's only when they're faced with obstacles, stress, and other environmental threats that resilience, or the lack of it, comes out. Some give in and some conquer.

    Garmezy's work opened the door to the study of the elements that could enable an individual's success despite the challenges they faced. His research indicated that some elements had to do with luck, but quite large set of elements was psychological, and had to do with how the children responded to the environment. The resilient children had what psychologists call an "internal lens of control(内控点)". They believed that they, and not their circumstances, affected their achievements. The resilient children saw themselves as the arrangers of their own fates.

    Ceorge Bonanno has been studying resilience for years at Columbia University's Teachers College. He found that some people are far better than others at dealing with adversity. This difference might come from perception(认知) whether they think of an event as traumatic(创伤), or as an opportunity to learn and grow. "Stressful" or "traumatic" events themselves don't have much predictive power when it comes to life outcomes. "Exposure to potentially traumatic events does not predict later functioning," Bonanno said. "It's only predictive if there's a negative response." In other words, living through adversity doesn't guarantee that you'll suffer going forward.

The good news is that positive perception can be taught. "We can make ourselves more or less easily hurt by how we think about things," Bonanno said. In research at Columbia, the neuroscientist Kevin Ochsner has shown that teaching people to think of adversity in different ways--to reframe it in positive terms when the initial response is negative, or in a less emotional way when the initial response is emotionally "hot"—changes how they experience and react to the adversity.

    A team of engineers at Harvard University has been inspired by Nature to create the first robotic fly. The mechanical fly has become a platform for a series of new high-tech integrated systems. Designed to do what a fly does naturally, the tiny machine is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks.

    "It's extremely important for us to think about this as a whole system and not just the sum of a bunch of individual components (元件)," said Robert Wood, the Harvard engineering professor who has been working on the robotic fly project for over a decade. A few years ago, his team got the go-ahead to start piecing together the components. "The added difficulty with a project like this is that actually none of those components are off the shelf and so we have to develop them all on our own," he said.

    They engineered a series of systems to start and drive the robotic fly. "The seemingly simple system which just moves the wings has a number of interdependencies on the individual components, each of which individually has to perform well, but then has to be matched well to everything it's connected to," said Wood. The flight device was built into a set of power, computation, sensing and control systems. Wood says the success of the project proves that the flying robot with these tiny components can be built and manufactured.

    While this first robotic flyer is linked to a small, off-board power source, the goal is eventually to equip it with a built-in power source, so that it might someday perform data-gathering work at rescue sites, in farmers' fields or on the battlefield. "Basically it should be able to take off, land and fly around," he said.

    Wood says the design offers a new way to study flight mechanics and control at insect-scale. Yet, the power, sensing and computation technologies on board could have much broader applications. "You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animals, but using these robots instead," he said. "So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day to day basis."

    A dog spent the last four years of his life waiting a crossroad in the Thai city of Khon Kaen as if waiting for someone. People originally thought the dog had been abandoned, but then realized that he looked healthy, so people asked around about him. It turned out that the dog had indeed been spending most of his time around that crossroad, but a woman had been coming -.round regularly to bring him food and water.

    One day, while photographing the dog everyone called Leo, a reporter met the woman who had been taking care of him. She had come to drop off some food. After learning the story about the dog and the woman, the reporter decided to share the story on social media. The post soon went viral and the photos of Leo got shared hundreds of times. And the photos reached the eyes of Leo^ former old owner.

    Nang Noi Sittisarn, a 64-year-old woman from Thailand's Roi Et Province, almost had a heart attack when her daughter showed her a photo of the beloved dog named BonBon she had lost during a car trip. When she learned that he had been waiting for her in the same spot for the last four years，her heart melted(融化).

    Auntie Noi told her daughter to drive her to where the dog was waiting. When she got there and called his name. BonBon, the poor dog started wiggling(扭动)his tail and came to her，but when she tried to take him home with her, he was unwilling to follow. She didn't want to force the dog to come with her so she agreed to leave him with his new master. However, she and her daughter will come to visit him regularly.
