Your next ca might drive itself. After years of trials on city streets, driverless vehicles are now nearing the live phase. Last moth, a driverless bus began carrying passengers through Lyon, France, Most in the automobile industry think self-driving vehicles will be on the road by 2020 or before.

    Driverless cars will at first be huddled with human-driven cars. But the first places where they will become dominant（统治的）are dense urban areas — precisely the spots most damaged by the automobile age. Many advanced cities are already reducing the role of human-driven cargo. Driverless cars will quicken that process and will bring us enormous benefits.

    Driverless cars will reduce accidents by around 90 percent. That's big—the annual death toll on the world's roads is about 1.2 million a year. Pollution and carbon emissions will drop, because urban driverless cars will be electric. The old, otherwise they would stay at home most of the time and the disabled and teenagers will suddenly gain mobility.

    On the other hand, driverless cars will bring catastrophe. The best thing about the automobile age was that it employed tens of millions of people to make, market, insure and drive vehicles. Over the next 20 years, the mostly low-skilled men who now drive trucks, taxis and buses will see their jobs reduced. Carmakers are especially scared. The few cars of the future might be made by tech companies such as Apple, Baidu and Google. Imaging the impact on Germany, where the automotive sector is the largest industry.

    Dramatic change is coming, and driverless cars could arrive by 2020. But governments have barely begun thinking about it. Only 6 percent of the biggest US cities have factored them into their long-term planning.

    A decade ago anyone hardly saw the Smartphone coming. It has bought an epidemic of mass addiction. Let's hope we do a better job of handling the driverless car.

    MySpace, the social networking website, is different from other websites which only provide stories about other people. MySpace is a place that allows you to broadcast your own stories and personal information to as many people as you like. Started two years ago, it is a big source of information for and about American kids.

    Teenagers and their parents feel very different about it. Teens are rushing to join the site, not sharing their parents' worries. It signals yet another generation gap in the digital era.

    For teenagers, it is reliable network to keep in touch with their friends. They will often list their surnames, birthdays, after­school jobs, school clubs, hobbies and other personal information.

    "MySpace is an easy way to reach just about everyone. I don't have all the phone numbers of my acquaintances. But if I want to get in touch with one of them, I could just leave them a message on MySpace, "said Abby Van Wassen. She is a 16­year­old student at Woodland Hills High of Pittsburgh, Pennsylvania.

    Parents on the other hand are seriously concerned about the security problems of MySpace. "Every time we hold a parents meeting, the first question is always about MySpace, "said Kent Gates, who travels the country doing Internet safety seminars(研讨会). The National Centre for Missing and Exploited Children has received at least 288 MySpace ­ related complaints, according to Mary Beth Buchanan, a lawyer in Pittsburgh.

    "Your profile on MySpace shows all your personal information to anyone on the Web. And MySpace even lists this information by birthplace and age. It's like a free checklist for troublemakers and it endangers children, " Buchanan said.

    An attractive novel from the author of the Sunday Times top 10 best seller. Five women go on a hike. Only four return.

    To start a conversation about the secret to happiness, ABC News' health editor Dr. Richard Besser hosted a Twitter chat Tuesday.  Experts from the National Institutes of Health, Mayo Clinic, Harvard University and TEDMED, as well as clinicians and people from across the country, joined the one-hour discussion. There are countless ways to measure happiness. With research on the topic increasing, researchers have carried out surveys to study people's sense of well-being.

    Angela Haupt, health and wellness editor for U.S. News and World Report, said, “Happiness indicators include life satisfaction, health and community engagement.”

    @toddkashdan added that, “despite problems with self-reports, there is no better way to measure happiness than focusing on personal thoughts and feelings.”

    While scientists try to find out what caused happiness, others often believe that true joy doesn't exist. Dr Friedman, a psychiatrist at New York Presbyterian-Weill Cornell Hospital, said that “happiness is hard to measure, but easy to recognize.”

    Still, common themes about satisfaction come up in these conversations. Finding meaning in daily work was important. Indeed, researchers have found that having creative and purposeful work to do is a key factor in happiness.  But people were quick to state the importance of balancing work and family obligations.

    Chat participants(参与者) agreed that money does not surely bring happiness. And studies agree once people's basic needs like food and housing are met, higher incomes do little to improve your happiness.  At last, people found value in their connections with others.  Research shows that having support through friends, family, and social networks can bring happiness.  Many agree with @drmommy, who said “I measure my happiness by the loving people that are around me.”

    So, can we increase our happiness?  Expressing gratitude(感激) is a possible way of feeling happiness. Researchers have found that people who regularly write down things for which they are grateful in “gratitude journals” have increased satisfaction in life, higher energy levels, and improved health.  In one study, people who read a letter of appreciation to someone in their lives prove happier almost one month later.  Performing acts of kindness can raise your moods

    Data show that our relationships matter, too. People who are interested in meaningful conversations with friends or family are reported to be happier than those who don't. Close interpersonal ties and strong social support are important for happiness.

    My family lives in Texas. I was born and brought up in Texas and I am a graduate of the University of Texas. However, around my second year in law school, I wanted to make a great change, which was almost unheard of for Texans: I wanted to leave!

    I realized this after completing my first year­year internship(实习期) I knew I wanted something different and my chance came during the 2011 Super Bowl in Dallas. A snowstorm blanketed the entire city in snow and thousands of people were gathered. I overheard that StubHub, a big company from a great city, San Francisco, was throwing a party next door to my hotel. I thought if l could get an internship, I could leave for the summer and at least see what it was like. Yes, it was a huge leap. I told myself I was ready.

    There was just one problem: I wasn't invited to the StubHub party. But you know I'm the type of person who goes for something she wants. Needless to say, I crashed the party and found my way to the president. I kindly introduced myself and then asked if they had a legal internship program. Guess what? They accepted my request to be a legal intern, even though no such program existed.

    Although the legal department didn't have a permanent position for me, the experience has shaped my life. Working for a great company in San Francisco, I'm incredibly happy for making my decision to leave Texas.

    By leaving Texas, I learned that it is so much more rewarding to try the unfamiliar than to stay in the comfortable. Exploring the unfamiliar is how you'll understand what fits your life. I say, dive in head first.

    Throughout history scientists have risked their health and their lives in their search for the truth.

    Sir Isaac Newton, the seventeenth century scientist, was very smart, but that didn't stop him from doing some pretty stupid things. In his laboratory in Cambridge he often did the strangest experiments. Once, while testing how light passes through lenses (晶状体), he put a long needle into his eye, pushed it to the back, and then moved it around just to see what would happen. Luckily, nothing long-lasting did. On another occasion he stared at the sun for as long as he could bear, to discover what effect this would have on his sight. Again he escaped suffering permanent damage, though he had to spend some days in a darkened room before his eyes recovered.

    In the 1750s the Swedish chemist Karl Scheele was the first person to find a way to produce phosphorus (磷). He in fact discovered eight more chemical elements including chlorine (氯), though he didn't get any praise for them. He was a very clever scientist, but his one failing was a curious habit of tasting a little of every substance he worked with. This risky practice finally caught up with him, and in 1786 he was found dead in his laboratory surrounded by a large number of dangerous chemicals, any of which might have been responsible for his death.

    Eugene Shoemaker was a respected geologist. He spent a large part of his life studying craters (火山口) on the moon, and how they were formed, and later did research into the comets of the planet Jupiter. In 1997 he and his wife were in the Australian desert where they went every year to search for places where comets might have hit the earth. While driving in the Tanami desert, normally one of the emptiest places in the world, another vehicle crashed into them and Shoemaker was killed on the spot. Some of his ashes (骨灰) were sent to the moon aboard the Lunar Prospector spacecraft and left there — he is the only person who has had this honor.
