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.”

    When important events are happening around the world, most people turn to traditional media sources, such as CNN and BBC for the news. However, during the war in Iraq in 2003, many people followed the war from the point of view of an unknown Iraqi citizen who called himself "Salam Pax" (Salam Pax means peace).

    Salam Pax wrote a diary about everyday life in Baghdad during the war, and posted it on his website. Pax's online diary was a kind of website known as a "blog". Blogs are online diaries, usually kept by individuals, but sometimes by companies and other groups of people. They are the fastest growing types of website on the Internet.

    A blog differs from a traditional website in several ways. Most importantly, it is updated much more regularly. Many blogs are updated every day, and some are updated several times a day. Also, most blogs use special software or websites, which can help ordinary people easily set up and start writing their own blogs.

    There are many different kinds of blogs. The most popular type is an online diary of links where the blog writer surfs the Internet and then posts links to sites or news articles that they find interesting, with a few comments about each one. Other types are personal diaries, where the writer talks about their life and feelings. Sometimes these blogs can be very personal.

    There is another kind of blogging, called "moblogging", short for "mobile blogging".

    Mobloggers use mobile phones with cameras to take photos, which are posted instantly to the Internet. The use of mobile phones in this way made the headlines in Singapore when a high school student posted a movie he had taken of a teacher shouting at another student on the Internet. Many people were shocked by what the student did, and wanted phones with cameras to be banned from schools.

    Many people think that as blogs become common, news reporting will rely less on big media companies, and more on ordinary people posting news to the Internet. They think that then the news will be less like a lecture, and more like a conversation, where anyone can join in.

    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 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 National Storytelling Youth Olympics is an event where thousands of kids from grades 6 to 12 compete against each other by telling stories. It is sponsored by the Master's Degree Program in Reading and Storytelling at East Tennessee State University. The sole purpose of this event is to promote and encourage both the art and science of storytelling among middle school and high school students. Although this event is competitive, its underlying intent and goal is to provide students across the nation with a reason to practice numerous noncompetitive skills.

    Those skills include skillful sportsmanship , responsible behavior, and an attitude of respect for others and the storytelling genre. The eventual goal of the National Storytelling Youth Olympics is to encourage every classroom in America to discover (or rediscover) the beauty of storytelling and story performance.

    The National Storytelling Youth Olympics takes place usually around the first weekend in March. Students from all over the country arrive by bus, plane, or automobile in Johnson City, Tennessee. They usually arrive on Thursday or Friday. Those that arrive on Thursday take advantage of their early arrival by telling stories at local schools. On Friday, an evening meal is prepared for all contestants, coaches, and parents. Games are played, stories are told, and lifetime friendships begin. Saturday is the day of the big event. A luncheon(午餐会) is held in the afternoon so contestants can familiarize themselves with the surroundings and do a sound check.

    The event is divided into three categories separated by grades. Contestants are judged not only by their storytelling performance, but also by the attitude and behavior they display during the entire weekend. A winner is picked from each of the three categories; however, there is an overall winner who is granted the name of Grand Torch Bearer. This person is selected not only by the judges, but also by the contestants. After the winners have been announced, the contestants retreat back to their hotel where a celebratory ice cream party is held; and believe it or not, they tell more stories! This is what the National Storytelling Youth Olympics is all about: developing a love for the art of storytelling.

15 years ago, Erin Merryn met a kitten who needed a home when she was a college student.

He jumped into her arms and refused to let her go.

"I was attached immediately and decided that I would take a risk and try hiding a kitten in my college dorm where animals are obviously not allowed," Erin recalled.

A week later she was caught and given 48 hours to remove the cat. After several phone calls, Erin was able to find an old lady to take Bailey, the kitten. But Bailey did not get along with his new housemate. As soon as Erin learned that he would be sent away, she immediately offered to take him back. "I plotted for a month to convince my parents to let me keep him." said Erin.

Six years ago, Erin had Abby, her beautiful daughter. She didn't know what Bailey would think about the new addition when she brought her home from the hospital.

"But it was love at first sight." Erin said. Bailey stayed by Abby's side, guarding and showering her with love and purrs. As Abby grew, he became her protective brother, watching over her every step of the way. Abby picked up a book one day and tried to read it with Bailey by her side. He became her perfect audience, and the sweet boy was completely attracted by Abby as she told him stories of wonder.

A video showing Abby reading to Bailey went viral on the Internet in 2018. Numerous people followed Erin on social media platforms.

Unfortunately, on December 8, 2018, just months after becoming famous, the 14-year old cat passed away from kidney failure.

A full month after Bailey's passing, Erin still got cards and gifts from caring individuals. It is this love that Erin hopes Bailey's fans hold on to. She wants her furry "first-born" to be remembered as a symbol of compassion that inspires others to treat the world with love.
