This could be the perfect gift for the partner, who embarrasses you on the dance floor. Smart socks, which can teach to dance, may be the answer for anyone with two left feet.

    The socks have been developed as a running tool to help runners improve their skills. Thanks to the socks, users can accurately record not only how far and fast they run but also how well. It means the user maximizes their performance, and reduces damage to body and prevents hurt. The hi-tech socks are made of special fibers that watch the movements of your feet. They look, feel and can be washed like normal clothes.

    Sensors (传感器) record each movement and send it by an ankle transmitter (脚踝发射器) to a smart phone. Then a “virtual coach” application shows the information and can tell the user what they are doing wrong, and help to improve skill in any task with feet.

    The socks should be useful to athletes and weekend joggers. “People think running is so easy and of course everybody can do it but not necessarily safely and well,” Dr Davide Vigano said. A recent study showed that between 60 and 80 percent of runners got hurt per year. This is pretty much more than any other human activity. Researchers say the technology can also be developed to teach people how to dance, play sports such golf, or even to help to teach women to walk better in high heels.

    Mr. Vigano said, “People could all benefit from the idea. We have had interest from all sorts of sports, like skiing, football, cycling and golf. Anything where you have to use your feet can use it. It could even be put in high heels to help women walk in them safely.”

    Socks are just the start, and the technology could be used in gloves, hats and boots. The socks, anklet and software package, are expected to be sold for around £120, which will go on sale in March.

Dearest darling girl,

    Today is the beginning of the next stage in your life. We head off to your new home at Stanford. Where do I start in telling you how proud I feel to be called Mummy by you? We've laughed at how you burst into this world with a scowl on your face, how determined you have always been right from feeding yourself to making big decisions for your life. There were days during your illness that I wasn't sure you had the will to make it. Telling you that you needed to want to get better was the hardest and yet the greatest day. From that day you took responsibility and decided you wanted to beat anorexia（厌食症）．

    I don't think I've ever felt so proud of you as when you came home to say that you wanted to go to West Africa between school and university. You chose to go alone, and to raise the money yourself. You have such strength of character and determination. It is at times hard to believe that you are only 18. You experienced something in that month that few dare experience in a lifetime.

    So, Viv, here are my words of wisdom to you as you start your next big adventure. The world is a beautiful place but often a few things can make it seem difficult. God's temple is made of love. It's man's temple that is built of stones. Open your heart to goodness and never ever let negative people or thoughts take hold of you. As Minor Myers put it, "Go into the world and do we'll. But more importantly, go into the world and do good:'

    It is true that with every passing day, I will grow older and weaker. A day may come when I will become forgetful. But even then, you with your bright smile, will light up my heart.

There is plenty of complaints about how social media-texting in particular—may be harming children's social and intellectual development. But a new study suggests that constant instant messaging (IM'ing) and texting among teens may also provide benefits, particularly for those who are introverted (内向的).

British researchers studied instant messages exchanged by 231 teens, aged 14 to 18. All of the participants were “regular” or “extensive” IM'ers. In the U. S., two thirds of teens use instant messaging services regularly, with a full third messaging at least once every day.

The researchers analyzed 150 conversations in the study, and reported the results in the journal Computers in Human Behavior. In 100 of these chats, the study participant began IM'ing while in a negative emotional state such as sadness, distress or anger. The rest were conversations begun when the participant was feeling good or neutral. After the chat, participants reported about a 20% reduction in their distress—not enough to completely eliminate it, but enough to leave them feeling better than they had before reaching out.

“Our findings suggest that IM'ing between distressed adolescents and their peers may provide emotional relief and consequently contribute to their well-being,” the authors write, noting that prior research has shown that people assigned to talk to a stranger either in real life or online improved their mood in both settings, but even more with IM. And people who talk with their real-life friends online also report feeling closer to them than those who just communicate face-to-face, implying a strengthening of their bond.

    Why would digital communication do better than human contact? The reasons are complex, but may have something to do with the fact that users can control expression of sadness and other emotions via IM without exposing emotional elements like tears that some may consider as embarrassing or sources of discomfort. Studies also show that the anonymity (匿名) of writing on a device blankets the users in a sense of safety that may cause people to feel more comfortable in sharing and discussing their deepest and most authentic feelings. The research has shown that expressive writing itself can vent the stress and provide a sense of relief—and doing so, knowing that your words are reaching a sympathetic friend, may provide even more comfort and potentially be therapeutic(治愈的). Researchers also found that introverted participants reported more relief from IM conversations when they were distressed than extroverts did. Susan Cain, author of Quiet wrote recently for TIME: Introverts are often overfilled with thoughts and care deeply for their friends, family and colleagues. But even the most socially skilled introverts sometimes long for a free pass from socializing or talking on the phone. This is what the Internet offers: the chance to connect—but in measured doses and from behind a screen.

    We may think we're a culture that gets rid of our worn technology at the first sight of something shiny and new, but a new study shows that we keep using our old devices（装置）well after they go out of style. That's bad news for the environment – and our wallets – as these outdated devices consume much more energy than the news ones that do the same things.

    To figure out how much power these devices are using, Callie Babbitt and her colleagues at the Rochester Institute of Technology in New York tracked the environmental costs for each product throughout its life – from when its minerals are mined to when we stop using the device. This method provided a readout for how home energy use has evolved since the early 1990s. Devices were grouped by generation. Desktop computers, basic mobile phones, and box-set TVs defined 1992. Digital cameras arrived on the scene in 1997. And MP3 players, smart phones, and LCD TVs entered homes in 2002, before tablets and e-readers showed up in 2007.

    As we accumulated more devices, however, we didn't throw out our old ones. "The living-room television is replaced and gets planted in the kids' room, and suddenly one day, you have a TV in every room of the house," said one researcher. The average number of electronic devices rose from four per household in 1992 to 13 in 2007. We're not just keeping these old devices – we continue to use them. According to the analysis of Babbitt's team, old desktop monitors and box TVs with cathode ray tubes are the worst devices with their energy consumption and contribution to greenhouse gas emissions（排放）more than doubling during the 1992 to 2007 window.

    So what's the solution? The team's date only went up to 2007, but the researchers also explored what would happen if consumers replaced old products with new electronics that serve more than one function, such as a tablet for word processing and TV viewing. They found that more on-demand environment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%.

    When Casey Waletich, the director of safety and operations at the Hillsboro School District in Oregon, decided to start a campaign against bullying (欺凌）in his district, he knew he had to get the students on board.

   "We knew that this had to be a student-led effort. The days of having schools do things without the involvement of the students are over，"Mr. Waletich says.

    So he got a group of students together and asked them how they would like to do things. The resulting campaign," Rethink, Redefine, Where Do You Stand?" was launched in October 2014.

    The Hillsboro campaign is just one example of how schools nationwide are increasingly turning to students to develop-anti-bullying movements designed to not just discourage bulling, but also to encourage students to get involved.

    In 2013, some 20 percent of high school students reported experiencing bullying, according to federal data on Stop Bulling gov. The figure jumps to 28 percent when middle school students are included. Some 70 percent of young people say they have witnessed bullying.

    In response to these issues, anti-bullying campaigns in which students have a central role are being conducted across the country. From West Jordan, Utah(where students participated in a three-year character-building program to stop bullying), to Lisbon, Iowa, and Goodrich, Mich, school officials report that their students are taking ownership.

   "This year I've noticed our students are already thinking about what they need to do to make Sunset Ridge an accepting, safe environment." Said Julie Scherzinger, a guidance councilor at Sunset Ridge Middle School in West Jordan." Students come up to me and ask if anyone needs help"

   "There are many reasons why having students at the center is most

important." Says Ron Avi Astor, a professor in social development at the University of Southern California in Los Angeles." Bullying takes place when adults are absent. The kids see and hear more and can go and inform adults when they aren't there to respond immediately"

   "Teaching kids to step up when someone is being bullied teaches them how to be responsible citizens." Ron Avi Astor added.
