“Our aim is to take our art to the world and make people understand what it is to move,” said David Belle, the founder of parkour(跑酷).

    Do you love running? It is a good exercise, yet many people find it boring. But what if making your morning jog a creative one? Like jumping from walls and over gaps, and ground rolls? Just like the James Bond in the movie Casino Royale? Bond jumps down from a roof to a windowsill and then runs several blocks over obstacles on the way. It is just because of Bond's wonderful performances that the sport has become popular worldwide.

    Yes, that's parkour, an extreme street sport aimed at moving from one point to another as quickly as possible, getting over all the obstacles in the path using only the abilities of the human body. Parkour is considered an extreme sport. As its participants(参与者) dash around a city, they may jump over fences, run up walls and even move from roof top to roof top.

    Parkour can be just as exciting and charming as it sounds, but its participants see parkour much more than that.

    Overcoming all the obstacles on the course and in life is part of the philosophy(理念) behind parkour. This is the same as life. You must determine your destination, go straight, jump over all the barriers as if in parkour and never fall back from them in your life to reach the destination successfully. A parkour lover said, “I love parkour because its philosophy has become my life, my way to do everything.”

    Another philosophy we've learnt from parkour is freedom. It can be done by anyone, at any time, anywhere in the world. It is a kind of expression of trust in yourself. It is only a state of mind. It is when you trust yourself that you earn energy.

    I will never forget the days when I met with my classmates. Early in the morning of our first school day, our professor introduced himself and challenged us to get to know someone we didn't know yet. I stood up look around when a gentle hand touched my shoulder. I turned round to find a wrinkled, little old lady beaming up at me with a smile that lit up her entire being.

    She said, “Hi handsome. My name is Rose. Can I give you a hug?”

    I laughed and enthusiastically responded, “Of course you may!” and she gave me a giant squeeze.

    “Why are you in college at such a young, innocent age?” I asked.

    She jokingly replied, “I'm here to meet a rich husband, get married, and have a couple of kids…”

    “No seriously,” I asked. I was curious what may have motivated her to be taking on this challenge at her age.

    “I always dreamed of having a college education and now I'm getting one!” she told me.

    After class we shared a chocolate milkshake. We became instant friends. Every day we would leave class together and talk nonstop. I was always mesmerized（迷住）listening to this “time machine” as she shared her wisdom and experience with me.

    At the end of the semester we invited Rose to speak at our football banquet. I'll never forget what she taught us.

    “There is only one secret to staying young. You've got to have a dream. When you lose your dreams, you die. We have so many people walking round who are dead and don't even know it! There is a huge difference between growing older and growing up. If I am eighty-seven years old and stay in bed for a year and never do anything I will turn eighty-eight. Anybody can grow older. That doesn't take any talent of ability. The idea is to grow up by always finding opportunity in change. Have no regrets. The elderly usually don't have regrets for what we did, but rather for things we did not do. The only people who fear death are those with regrets.”

    She concluded her speech by courageously singing The Rose. She challenged each of us to study the lyrics and live them out in our daily lives.

    The Queen has had to say goodbye to one of her longtime companions, her beloved pet corgi Holly, who has sadly passed away aged 13. The corgi will probably be familiar to royal fans who would recognize her from the 2012 London Olympics opening video.

    The dog was suffering from old age and was put down at Balmoral after suffering from an illness, leaving Her Majesty three surviving pet dogs, Willow and two corgi-dachshund crosses, Vulcan and Candy.

    According to a spokesperson for Buckingham palace, the Queen was deeply upset by Holly's passing and she doesn't like seeing her dogs suffer. Holly had attained a very good age. She gets more unsettled if they suffer and she knows that putting a dog down is often the kindest solution. She was devoted to Holly and wherever the Queen was, the dog was never far behind.

    Holly was included in one of the portraits for the Queen's 90th birthday, along with her other three pet dogs. Although the Queen usually has several pet corgis, it was recently revealed that she is keen not to breed（繁殖）any more of the dogs. Monty Roberts, a horse trainer who has previously given advice to Queen, told the Daily Mail, “She wouldn't leave any young dogs behind if she died. She wanted to put an end to it. Her Majesty had previously named one of her dogs after her friend, but the dog died in 2012. Dogs love for less time than human beings and we know we're going to lose them—but they are part of the Queen's family. She'll be quite upset.”

    Why do some people live to be older than others? You know the standard explanations: keeping a moderate diet, engaging in regular exercise, etc. But what effect does your personality have on your longevity(长寿)? Do some kinds of personalities lead to longer lives? A new study in the Journal of the American Geriatrics Society looked at this question by examining the personality characteristics of 246 children of people who had lived to be at least 100.

    The study shows that those living the longest are more outgoing, more active and less neurotic (神经质的) than other people. Long-living women are also more likely to be sympathetic and cooperative than women with a normal life span. These findings are in agreement with what you would expect from the evolutionary theory: those who like to make friends and help others can gather enough resources to make it through tough times.

    Interestingly, however, other characteristics that you might consider advantageous had no impact on whether study participants were likely to live longer. Those who were more self-disciplined, for instance, were no more likely to live to be very old. Also, being open to new ideas had no relationship to long life, which might explain all those bad-tempered old people who are fixed in their ways.

    Whether you can successfully change your personality as an adult is the subject of a longstanding psychological debate. But the new paper suggests that if you want long life, you should strive to be as outgoing as possible.

    Unfortunately, another recent study shows that your mother's personality may also help determine your longevity. That study looked at nearly 28,000 Norwegian mothers and found that those moms who were more anxious, depressed and angry were more likely to feed their kids unhealthy diets. Patterns of childhood eating can be hard to break when we're adults, which may mean that kids of depressed moms end up dying younger.

    Personality isn't destiny, and everyone knows that individuals can learn to change. But both studies show that long life isn't just a matter of your physical health but of your mental health.

    It is becoming increasingly important for researchers to closely monitor our ocean life. However, observing sea creatures up close is almost impossible since human presence scares them. Now, thanks to The Soft Robotic Fish, also known as SoFi, researchers may be able to keep a close eye on the sea creatures.

    Built by MIT Computer Science and Artificial Intelligence Laboratory (CSAIL), the white re- mote-controlled robot resembles the real fish, complete with a tail that waves from side to side. Though not the first autonomous underwater vehicle (AUV) created to monitor the ocean, SoFi settles many of the problems that have blocked the usefulness of the previous robot fish.

    Previous AUVs have had to be linked to boats because radio frequency communications don't work well underwater. To overcome the problem, Director of the CSALL Daniela Rus and her team used sound waves. The technology can travel greater distances allowing divers to pilot SoFi from up to 50 feet away.

    Also limiting the usefulness of traditional AUVs is the risk of collision. With the outside made of soft silicone (硅树脂) rubber and flexible plastic that keeps its inbuilt electronics dry, SoFi poses no such danger. "Collision avoidance often leads to unnecessary movement, since the robot has to settle for a collision-free path", says Rus. "In contrast, a SoFi robot is not only more likely to survive a collision but also could use it as information to form a more workable movement plan next time around."

    During test dives, SoFi moved alongside the ocean life at depths of 50 feet for up to 40 minutes at a time, taking photos and making videos. The researchers say sometimes the fish would swim a- longside the strange-looking robot-fish out of curiosity, while at other times they took no notice of its existence.

    While SoFi presently only records video, future versions will include sensors. The researchers also hope to make it more autonomous. "We imagine someday it might help us uncover more secrets from the amazing underwater world that we know so little about," says Rus.

    While famous foreign architects are invited to lead the designs of landmark buildings in China such as the new CCTV tower and the National Center for the Performing Arts, many excellent Chinese architects are making great efforts to take the center stage.

    Their efforts have been proven fruitful. Wang Shu, a 49-year-old Chinese architect, won the 2012 Pritzker Architecture Prize—which is often referred to as the Nobel Prize in architecture—on February 28. He is the first Chinese citizen to win this award.

    Wang serves as head of the Architecture Department at the China Academy of Art (CAA). His office is located at the Xiangshan campus (校园) of the university in Hangzhou, Zhejiang Province. Many buildings on the campus are his original creations.

    The style of the campus is quite different from that of most Chinese universities. Many visitors were amazed by the complex architectural space and abundant building types. The curves (曲线) of the buildings perfectly match the rise and fall of hills, forming a unique view.

    Wang collected more than 7 million abandoned bricks of different ages. He asked the workers to use traditional techniques to make the bricks into walls, roofs and corridors. This creation attracted a lot of attention thanks to its mixture of modern and traditional Chinese elements (元素).

    Wang's works show a deep understanding of modern architecture and a good knowledge of traditions. Through such a balance, he had created a new type of Chinese architecture, said Tadao Ando, the winner of the 1995 Pritzker Prize.

    Wang believes traditions should not be sealed in glass boxes at museums. "That is only evidence that traditions once existed," he said.

    "Many Chinese people have a misunderstanding of traditions. They think tradition means old things from the past. In fact, tradition also refers to the things that have been developing and that are still being created," he said.

    "Today, many Chinese people are learning Western styles and theories rather than focusing on Chinese traditions. Many people tend to talk about traditions without knowing what they really are," said Wang.

    The study of traditions should be combined with practice. Otherwise, the recreation of traditions would be artificial and empty, he said.
