A Dutch artist and designer has come up with a device which he hopes will get rid of pollutants from Beijing's smog skies, creating clean air for the city's mask-wearing people.

    An electromagnetic field（电磁场） will pullparticles（微粒） in the smog to the ground where they can be easily cleaned.

“It's like when you have a balloon which has static（静电） and your hair goes toward it. Same with the smog,” says artist Daan Roosegaarde.

    His studio has reached an agreement with the Beijing government to test the technology in one of tile capital's parks.

    With its skies regularly covered by dirty gray smog, Beijing this week announced a series of emergency measures to handle the problem.

    Roosegaarde says an indoor model device has already proven it works and is confident that the results — with the help of a team of scientistsand engineers — can be replicated outside.

  “Beijing is quite a good place because the smog in Beijing is quite low. It lies in a valley so there's not so much wind. It's a good environment to explore this kind of thing.”

  “We'll be able to purify the air and the challenge is to get the top of the smog so you can see the sun again.”

    Roosegaarde acknowledges that projects like this are a way of drawing attention to the problem, rather than a practical solution to Beijing's awful air pollution.

  “This is not the real answer for smog. The real answer has to do with clean cars, different industry and different lifestyles.”

    However, he hopes the project will make a “fundamental statement” by allowing the city's people to realize the difference between breathing clean and smog-filled air.

    A world-famous Canadian author, Margaret Atwood, has created the world's first long-distance signing device(装置), the LongPen.

    After many tiring……from city to city, Atwood thought there must be a better way to do them . She hired some technical experts and started her own company in 2004. Together they designed the LongPen. Here's how it works: The author writes a personal message and signature on a computer tablet(手写板) using a special pen. On the receiving end, in another city, a robotic arm fitted with a regular pen signs the book. The author and fan can talk with each other via webcams(网络摄像机) and computer screens。

    Work on the LongPen began in Atwood's basement(地下室). At first, they had no idea it would be as hard as it turned out to be. The device went through several versions, including one that actually had smoke coming out of it. The investing finally completed, teat runs w ere made in Ottawa, and the LongPen was officially launched at the 2006 London Book Fair. From here , Atwood conducted two transatlantic book signings of her latest book for fans in Toronto and New York City.

    The LongPen produces a unique signature each time because it copies the movement of the author in real time. It has several other potential applications. It could increase credit card security and allow people to sign contracts from another province. The video exchange between signer and receiver can be recorded on DVD for proof when legal documents are used.

     “It's really fun”, said the owner of a bookstore, who was present for one of the test runs. “Obviously you can't shake hands with the author but there are chances for a connection that you don't get from a regular book signing..

    The response to the invention has not been all favorable. Atwood has received criticism from authors who think she is trying to end book tours. But she said, “It will be possible to go to places that you never got sent to before because the publishers couldn't  afford it.”

    Last Thursday, Michael and Linda stood behind large food trucks distributing meals to 4,000 homeless people for their wedding reception on the border town of Kilis. The couple had decided that instead of hosting their friends and family for a traditional feast reception, they would feed the victims from an earthquake-stricken area.

    The idea came from the bridegroom's father, Ted, who volunteers for a Turkish relief organization. For the past few years, the organization has distributed daily meals to thousands of people who've suffered from natural disasters. He approached a representative of the organization and suggested that the family cover part of the costs of feeding them for the day.

    Then he told his son, who was surprised by the suggestion, but soon won over. When he told that to the bride, she was really shocked but finally accepted because in southeastern Turkey there is a real culture of sharing with people in need. They love to share their food, their table and everything they have. And afterwards she was quite amazed about it. So, they arrived at the distribution center on Thursday to spend the day serving food and taking photographs with their grateful recipients（接受者）．

    On Tuesday evening, the newly married couple were still pleased with their decision to quit a personal celebration for one with a greater good. "It's like sharing a dinner with your friends and family who have this kind of thing on a daily basis or sharing something with people who don't even have the most basic things," Michael said. "Hopefully, this will also give the start for other wedding dinners to be held here with our brothers and sisters in need."

    Today show's Kathie Lee Gifford is hoping to bring the story of David to a new generation with her latest musical project, The Little Giant.

    The 13-song album tells the story of the shepherd (牧羊人) boy who defeated a giant with five stones and a slingshot and became a king. The idea of the record came after Gifford and her husband Frank went on a life-changing trip to the Holy Land in 2012.

    Gifford hoped to shine light on David's story to help a new generation find their own purpose; it's why she decided to compose this album that invites kids to hear the tale of the shepherd in a fun and educational way. Gifford based the record's opening track "What is Your Stone" on bravery and faith. She hopes the songs can help children find confidence in themselves.

    Though the album is aimed towards families and children, Gifford found recording the story of David to be an exercise in healing after the death of her beloved husband Frank who passed away two years ago.

    "I catch myself saying that I lost him sometimes," Gifford says, "No, he hasn't been gone. The trip took root in my husband's life, because he truly came to understand exactly what David did. "

    Gifford says the trip and the teachings stayed with her husband until his death. 66For the next three years, when people came to visit us, they'd always see Frank's trophy (奖杯) room because it's like a museum," Gifford explained. "He would take them over. Instead of all of his trophies, he would point to the stones we brought back from the travelling destination and talk a out them. "

    Gifford expects her own journey, her new album and her commitment to bringing a bit of joy to people through her show can help inspire children to discover their own faith and purpose.

    For the past two years I have been travelling and living abroad. Home has become more of a feeling than a place. I feel at home when I am with my family in London, but I also feel at home in Italy with friends I love. Home is no longer a picture of a house with a front door and some windows. It is more complicated than that.

    This is one of the reasons that celebrating the new year has become very important for me. I do not care about "New Year's resolutions (愿望)"—living abroad has made me constantly reconsider what kind of person I want to be and how I will live my life, so I don't feel the need to plan for change: I live for change.

    New Year's Eve has become my time to reconnect with the friends that makes me feel at home. Every year we try to reunite wherever we are and remember the time when we knew each other so well that we felt like a family. It is a moment to reconnect and get to know each other again. Last year, we travelled to a cottage in Ireland where we had no internet and no neighbours. In the middle of the countryside, away from our big and constantly changing lives, we were able to become like a little family again.

    This year, we went to Barcelona. It was a very big change. We were surrounded by culture and life and joy. There were bars and parties. It was different, but one thing stayed very much the same-I felt at home again and we felt like a family again.

    A lot of people feel that New Year's Eve cannot live up to expectations. Ideas such as the "New Year's kiss" and "resolutions" create a lot of pressure for people to have a night to remember, a night that will change their lives and perhaps make the next year one worth living. I think those people are missing the point. If Christmas is about family, why can't New Year be about friends?

    Rock climbing is not just for grown-ups. Your children can also enjoy this fun-filled activity as well as getting its advantages. Aside from its heart-health benefit, it is also known to increase their self-confidence and esteem(尊重). While it may not be an impromptu(即兴的) activity like running or biking, there are many climbing walls that are now available, especially with the development of fitness centers and camps.

    The great thing about having your kids join these activities is that it follows up on their natural quality. As you know, children are natural climbers. You can see them going up on trees or climbing tall ladders. With rock climbing, you can satisfy their urges to be a climber.

    What's more, it is fairly easy for the kids compared with adults. With a high strength-to-weight rate, they have less body weight to pull up, and they are more flexible(灵活的).

    It is also a low-impact workout that tests your children's endurance(耐性). It's easy on their joints(关节) as they burn energy during their ascent. In addition, climbing walls are like giant puzzles begging to be solved. Not only does it test the physical aspects of your children's development, but it also wakes their mental abilities.

    This exercise also helps develop your children's essential strength and flexibility. Kids are challenged physically as they pull, lift, stretch, and twist their way up. This activity also develops their eye-hand coordination(协调) as they perform their climb.

    Almost anyone can do it although it may vary in skill level, namely beginner, intermediate, or advanced. But despite its reputation as an extreme sport, children can do this. One does not need to be super-fit to join a rock climbing class. However, good technique is more necessary than strength when doing this sport.
