Orville Wright was born on August 19, 1871 in Dayton, Ohio, USA and died on January 30, 1948. Together with his brother, Wilbur, he was the first airplane builder. The brothers created the first controlled, powered and heavier-than-air human flight.

    His parents were Milton Wright and Susan Catherine Koerner and besides the two famous brothers they had five children. One day after a trip his father brought as a gift a small helicopter. The kids loved it and as they played daily with it after a while it broke. The brothers managed to create a new one. Wright even let go his plans of attending Yale. He spent his time helping his ill mother and reading in his father's library.

    In 1884 the family decided to move to Dayton and they remained there until the 1870's. A printing press was built by the two and Wilbur was an editor. In 1892 they started being fascinated by the aeronautical （航空的） events of that time. Then they started to create an airplane and Wilbur was considered the head of the team. They were the inventors of “three axis-control”, which permitted the pilot to steer the aircraft's balance.

    In 1900 they had their first attempts to make a functional glider（滑翔机）— of course it didn't have a pilot. After three years they thought of introducing an engine to the glider. At first, their patent(专利) application was refused in 1903, but after one year it was accepted.

    Orville's first flight lasted 12 seconds and had 36.5 meters. He was responsible with the public shows near Washington in the United States. On September 9, 1908 his flight was 62 minutes and 15 seconds long and the success was huge.

    Self-driving vehicles(车辆) will rely on cameras, sensors and artificial intelligence (人工智能) to recognize and respond to road and traffic conditions, but sensing is the most effective for objects and movement in the neighborhood of the vehicle. Not everything important in a car's environment will be caught by the vehicle's camera. Another vehicle approaching at high speed on a collision (碰撞) track might not be visible until it's too late. This is why vehicle-to-vehicle communication is undergoing rapid development. Our research shows that cars will need to be able to chat and cooperate on the road, although the technical challenges are still great.

    The usages of vehicle-to-vehicle communication contain vehicles driving together in a row, as well as safety messages about nearby emergency vehicles. Vehicles could alert each other to avoid collisions or share notices about passers-by and bicycles. From as far as several hundred metres away, vehicles could exchange messages with one another or receive information from roadside units（RSUs）about nearby incidents or dangerous road conditions through 4G network. A high level of AI seems required for such vehicles, not only to self-drive from A to B, but also to react intelligently to messages received. Vehicles will need to plan, reason, strategize and adapt according to information received in real time and to carry out cooperative behaviors. For example, a group of autonomous vehicles might avoid a route together because of possible risks, or a vehicle could decide to drop someone off earlier due to messages received, a foreseen crowding ahead.

    Further applications(应用) of vehicle-to-vehicle communication are still being researched, including how to perform cooperative behavior.

    In the latter part of the 20th century, child labor remains a serious problem in many parts of the world. Studies carried out in 1979, the International Year of the Children, showed that more than 50 million children below the age of 15 were working in various jobs often under dangerous conditions. Many of these children live in underdeveloped countries in Latin America, Africa, and Asia. Their living conditions are crude and their chances for education small. The poor income they bring in, however, is necessary for the survival of their families. Frequently, these families lack the basic necessities of life—adequate food, decent（得体的、合适的）clothing and shelter, and even water for bathing.

    In some countries industrialization has created working conditions for children that are comparable to the worst features of the 19th-century factories and mines. In India, for example, some 20,000 children work 16-hour days in match factories.

    Child-labor problems are not, of course, limited to developing nations. They occur wherever poverty exists in Europe and the United States. The most important efforts to eliminate（根除）child-labor abuses throughout the world come from the International Labor Organization (ILO), founded in 1919 and now a special agency of the United Nations. The organization has introduced several child-labor conventions（规定）among its members, including a minimum（最低）age of 16 years for admission to all work, a higher minimum age of specific types of employment, compulsory（强制的）medical examinations, and It depends on voluntary obedience（服从）of member nations.

    Like all big cities, Paris has a traffic problem: lots of cars, lots of traffic jams and lots of pollution from exhaust fumes (废气). So the city began a project to improve the situation.

    Under the Velib project ('Velib' comes from vélo liberté, or 'bicycle freedom') people can take a bicycle, use it for as long as they want, and then leave it at the same or another bicycle station. The first half-hour on the bike is free, but if you don't return it after 30 minutes, you have to pay. But it's only €1 a day or €29 a year! The bicycles are heavy (25 kg), and they are all grey and have baskets. There are about 20,000 of them in the city, and around 1,450 bicycle stations. So there are a lot more Velib stations than the 298 subway stations!

    Paris is not the first city to have a project like this. But not everybody thinks it's a great idea. One Parisian said, “These bicycles are only for short journeys. If people want to travel across the city, they won't use a bicycle — they'll still use their cars.”

    A city spokesman said, “The bicycle project won't solve all our traffic problems, of course. But it might help reduce air pollution. Traffic, together with factory fumes, is a big problem. There aren't any simple answers to traffic problems and pollution in cities. But unless we do something now, there will be more traffic jams and temperatures will continue to rise, so the problems in our environment will get worse. The bikes might help people to lead a healthier life, too.”

    More and more comments sections are being shut down online.

    Autumn Phillips had had enough. On Aug. 19, the executive editor of the Quad- City Times in Iowa, and Illinois, US visited her website, qctimes.com, and saw a story about a man who had been shot to death. When she got to the readers' comments sections at the end, she was shocked by what she saw. Below the story was a growing number of comments—a racist remark about democratic votes, a negative comment about police …So Phillips decided to do something she had been thinking about for a long time: she shut down the comments sections.

    Phillips was not alone in making such a move. Last week, NPR announced k too was closing its online comments sections. The decisions don't mean that the news outlets are no longer interested in what their audiences are thinking. Both stressed their eagerness to hear from readers and listeners on social networks. But both agreed that comments had deviated from their original intention. And so they had.

    In early days of digital journalism, comments were seen as a key part of this new media, a wonderful opportunity for strengthening the dialogue between news producers and their audiences. It was a welcome change, given that for long many news organizations were far too separated from their readers. Much more back and forth conversation seemed like healthy and welcome evolution. Sadly, that's not the way things turned out. Rather than a place for exchanging ideas, comments sections became the home of ugly name-calling, racism and anti-women language. Besides their poisonous quality, comments seem out of place today.

    "Since we made the announcement, I've received an outpouring of responses from our readers," she says. "I've heard from parents whose children were hurt by our online comments. I've heard from people who said they wouldn't send in letters to the editor because they were attacked so fiercely by comments, and wasn't worth it."

    A new "paparazzi-proof" scarf has got heatedly welcomed since launched. A new "paparazzi-proof" scarf could be a game-changer for celebrities who prefer to shy away from the stage light. The ISHU scarf is the creation of Dutch-born fashion entrepreneur Saif Siddiqui and is designed to "give people their right to privacy back". A host of celebrities including Cameron Diaz, singer Joe Jonas, Bayern Munich footballer Jerome Boateng and music producer Major Lazer have worn the ISHU after it was spotted at London Fashion Week last year.

    It works by reflecting the light back into a camera, effectively becoming "invisibility clothes" for celebrities who don't want their photos taken. Anyone wearing the scarf is protected from mobile flash photograph, with the fashion accessory's fabric (附件结构) effectively blocking out any unwanted pictures, although it doesn't stop no-flash photographs from being taken.

    The 28-year-old Siddiqui was inspired while visiting family in Amsterdam in 2009 when his friends attempted to take a photo of him using an iPhone in front of some bikes. "He noticed that the bike's reflector carried the flash of his mobile camera in a way that confused the faces of his friends in the picture." the ISHU website explains. "He immediately realized that if developed into the right product, this feature would be an ideal solution for his friends and is now available to the public who want to keep their private moments in public private. "Saif put together a team of experts who dug into the science of light and reflection, and how to blend technology with fashion."

    He told Decoded Magazine: "The ISHU scarf effectively allows an individual to control what pictures and videos are taken of him. "There are no more unwanted pictures and videos on Snapchat, Instagram, or Facebook! Everyone carries a phone with them nowadays that has an amazing camera. So, it all made sense to me." More ISHU products are set to launch in August, with mobile phone cases set to launch in the next few weeks. The ISHU is currently sold out but you can pre-order it online for ￡289.
