As more and more people speak the global languages of English, Chinese, Spanish, and Arabic, other languages are rapidly disappearing. In fact, half of the 6，000～7，000 languages spoken around the world today will likely die out by the next century, according to the United Nations Educational, Scientific, and Cultural Organization (UNESCO).

    In an effort to prevent language loss, scholars from a number of organizations—UNESCO and National Geographic among them—have for many years been documenting dying languages and the cultures they reflect.

    Mark Turin, a scientist at the Macmillan Centre, Yale University, who specializes in the languages and  oral traditions of the Himalayas, is following in that tradition. His recently published book, AGrammarofThangmiwithanEthnolinguisticIntroductiontotheSpeakersandTheirCulture, grows out of his experience living, working, and raising a family in a village in Nepal.

    Documenting the Thangmi language and culture is just a starting point for Turin, who seeks to include other languages and oral traditions across the Himalayan reaches of India, Nepal, Bhutan, and China. But he is not content to simply record these voices before they disappear without record.

    At the University of Cambridge Turin discovered a wealth of important materials—including photographs, films, tape recordings, and field notes—which had remained unstudied and were badly in need of care and protection.

    Now, through the two organizations that he has founded —the Digital Himalaya Project and the World Oral Literature Project—Turin has started a campaign to make such documents, found in libraries and stores around the world, available not just to scholars but to the younger generations of communities from whom the materials were originally collected. Thanks to digital technology and the widely available Internet, Turin notes, the endangered languages can be saved and reconnected with speech communities.

    In Asia, there are special competitions where kites have complex designs and are fitted with instruments that make musical sounds as the wind blows through them. Although all kites have a similar structure （结构）, they are widely different in size and shape. Kite-fighting competitions are also held, in which competitions us their kites to attack and bring down their opponents'（对手）kites or cut their strings（线）.

    For more than 15 years, the Big Wind Kite Factory has been giving kite-making and kite flying classes for the children on an island in Hawaii. In its kite-making lessons, students can make kites in as little as 20 minutes! Children as young as four years old can learn how to fly a kite. Jonathan Socher and his wife Daphne started the kite factory in 1980. Their kites are made of nylon（尼龙）.Their designs are Hawaiian themes created by Daphne. The designs are cut out of the nylon with a hot knife that seals the edges and then fastened directly onto the kite. 

    The kite that is used to give lessons is a regular diamond kite with a rainbow pattern. The difference between this kite and the ones they make during the lessons is that it is a two-string controllable kite. Big Wind employees fly the kite and for a few minutes show students how pulling on one line and then on the other controls the direction the kite goes in. Then the controls are given to the students.

    Jonathan insists that it is not necessary to make a huge impressive kite to have fun making and flying kites. Even the simplest structure can work, and can give hours of fun. Go on, give it a try!

    In 1994 I wrote a letter. I stuck it in an envelope, put it away and completely forgot about it. It wasn't until we moved into our new home in 2006 that I found it again. It was addressed to me with explicit instructions not to open until my birthday 2005. It was now 2006 so I decided to open it. This is what it said: Dear Sherri.

    By the time you read this you will be 30. At the age of 18 I had so many hopes and dreams about where you'd be, what you'd be doing and with whom you'd spend your life with.

    Right now I hope that you have traveled and seen everything you've always wanted to, both in Canada and overseas, and maybe even settled down somewhere in Australia doing some research in the field of biology (genetics).I hope you're married to the man of your dreams. The man of mine is Gwynn. He is originally from South Africa (another place I wish to visit).

    However, if things don't go according to plan for you, I wish you all the love, happiness and joy in the world and don't settle for anything less than the best since that is absolutely what you deserve.

    Live long, be happy and live life to it's fullest.

    Love Sherri "18"

    When I read this for the first time since writing it I was floored. Even now having dug this up again another 4 years later I still can't help but think this is really cool. So much of what I wanted for myself has materialized. I did travel to a few more places in Canada although I haven't seen everything I'd like to.

    I did marry the man of my dreams and yes he still is my one and only. I lived in Australia for nearly 4 years, I had a career in Biology in the field of genetics for 10 years. I have two lovely kids I have not one dog but two dogs. Gwynn is a computer programmer.

    I suppose these were things that I really did want. Having never strayed too far from home overseas travel was a huge deal. Having never been away from my family moving to Australia for several years was an huge decision. I find it fascinating how the dreams of a young and naive little girl can become a grown woman's reality.

    How about writing a letter now to yourself in, say, 10 years from now? It's an interesting experiment.

    The problem of robocalls has gotten so bad that many people now refuse to pick up calls from numbers they don't know. By next year, half of the calls we receive will be scams(欺诈). We are finally waking up to the severity of the problem by supporting and developing a group of tools, apps and approaches intended to prevent scammers from getting through. Unfortunately, it's too little, too late. By the time these "solutions" become widely available, scammers will have moved onto cleverer means. In the near future, it's not just going to be the number you see on your screen that will be in doubt. Soon you will also question whether the voice you're hearing is actually real.

    That's because there are a number of powerful voice manipulation (处理) and automation technologies that are about to become widely available for anyone to use. At this year's I/O Conference, a company showed a new voice technology able to produce such a convincing human-sounding voice that it was able to speak to a receptionist and book a reservation without detection.

    These developments are likely to make our current problems with robocalls much worse. The reason that robocalls are a headache has less to do with amount than precision. A decade of data breaches(数据侵入)of personal information has led to a situation where scammers can easily learn your mother's name, and far more. Armed with this knowledge, they're able to carry out individually targeted campaigns to cheat people. This means, for example, that a scammer could call you from what looks to be a familiar number and talk to you using a voice that sounds exactly like your bank teller's, tricking you into "confirming" your address, mother's name, and card number. Scammers follow money, so companies will be the worst hit. A lot of business is still done over the phone, and much of it is based on trust and existing relationships. Voice manipulation technologies may weaken that gradually.

    We need to deal with the insecure nature of our telecom networks. Phone carriers and consumers need to work together to find ways of determining and communicating what is real. That might mean either developing a uniform way to mark videos and images, showing when and who they were made by, or abandoning phone calls altogether and moving towards data-based communications — using apps like FaceTime or WhatsApp, which can be tied to your identity.

    Credibility is hard to earn but easy to lose, and the problem is only going to get harder from here on out.

    With the explosion of consumer choices in recent history, the latest must-haves would surely need to be upgraded more often than every 10 years. In 2002 a computer and basic mobile phone would have been enough for most people, but now? The public need a trendy notebook computer and a smart phone with WiFi connection to feel they are up-to-date. So when will we have enough things? When will we finally be happy? Well, it looks like the things we buy today will barely keep us satisfied for a few months.

    In the eyes of some psychologists, far from making us happy, greater consumer choice creates many serious psychological problems. A fundamental principle of the society is that more freedom is better and more choice in the marketplace means more freedom. Therefore more choice leads to more happiness. This is not the case, however.

    Imagine you go to a café offering chocolate and vanilla ice cream. You choose the chocolate and eat it happily. But what if the café serves 50 kinds of ice cream? You choose chocolate and then start to worry, "maybe blueberry would have been better, perhaps the half-fat ice cream would have been healthier. Stupid me, all these choices and I didn't make the best one! "

    In China's major cities we have now passed the point where more consumer choice is making us happier. We are annoyed by all the options we have, disappointed because our expectations are so high and angered at ourselves when we don't make a perfect choice every time.

    A newspaper reporter tells a story about traveling on a plane with high-speed Internet access. He thought this was amazing—the newest piece of technology he had heard of. Then the service went down. The man next to him was angry and swore. The reporter thought, "How quickly the world owes him something he knew existed only 10 seconds ago!"

Researchers at MT created a high-tech pill that starts to vibrate(震动) once it makes contact with liquid in the user's stomach and make him or her feel full. The pill was reportedly thought up by Shriya Srinivasan, currently an assistant professor of bioengineering at Harvard University.

VIBES, short for Vibrating Ingestible BioElectronic Stimulator，was only recently made public in a study published in the Science Journal, but it is already being announced by the media as the future of weight loss. Although it has yet to be tested on humans, trials on pigs have achieved very hopeful results. After about 30 minutes of VIBES activity, pigs consumed on average almost 40 percent less food in the next half hour than they did without the smart pill. Apparently, the revolutionary device works by activating stretch receptors in the stomach, modeling the presence of food. This in turn signals the hypothalamus(下丘脑) to increase the levels of hormones that make us feel full. The vibrating stimulator, which is about the size of a vitamin pill, is powered by an encased battery and activated either by the gastric fluid(胃液) breaking down a coat around the pill, or by an incorporated timer. After producing the desired effect, the pill exits the body with other solid waste.

The good news is that it is expected to have a cost in the cents to one dollar range, and researchers say that it may eventually be possible to implant the stimulator and thus remove the need for people to constantly swallow it.

"Our study demonstrates the effectiveness of a low-cost, non-operative intervention to reduce food intake and calorie consumption. The device functions effectively in the stomach and leading to fullness," said Giovanni Traverso, co-author of the study. "The device has the potential to revolutionize options for weight loss treatment. However, future studies will need to explore the physiological effects of the device before it's available for patients."

Researchers are now exploring ways to scale up the producing of VIBES capsules which could enable clinical trials in humans.
