Quicker and faster 3-D printers have allowed not just amazing objects to be created, but have started to affect how doctors treat patients.

    We've put together a list of some of the most amazingmedical break throughs made possible with 3-D printing.

Life-Saving Airway

    In 2013, doctors created a new airway for kaiba Gionfriddo, aboy born with an airway that kept collapsing (萎陷). To save his life doctors printed tiny tubes to join together in different shapes and sizes until one finally worked for Kaiba. It was placed in Kaiba's bronchus (支气管) so that it no longer collapsed. Even more remarkably, once the plant was placed it couldstay there. It's designed to eventually be absorbed into the body.

New “Bionic” Hands

    One of the most remarkable ways 3-D printing is now being used is as a way to create prosthetics (假肢). A boy born without an arm named Alex was able to get a new“bionic”hand thanks to it. Last year a college student spent 8 weeks coming up with a special prosthetic design that only cost a few hundred dollars in materials. He said he wanted to create a prosthetic far cheaper than other choices that can run tens of thousands of dollars.

A practice Heart

    In Seattle, doctors have been able to use 3-D printing technology to“practice”risky operations so that they will face fewer surprises in the operating room. Kami Sutton was born with her heart“in the wrong place”. For a recent operation her doctor was able to take many scans of Sutton's heart and print out a model. “Kami's heart is truly one-of-a-kind,”Dr. Stephan Seslar, a heart disease specialist said. “Operating on her without understanding the structure of her heart better could be very dangerous.”

A New Skull

    A U.K. man was able to have part of his skull rebuilt thanks toa 3-D printer. Stephen Power broke his cheek bones in a crash. To help Powerh is doctors instead created 3-D bones all carefully printed in the shape of his face. “This is really the first time we've taken it to this stage, where everything has been planned and modeled in advance — and worked sweetly,”said Adrian Sugar, a doctor.

    More over smart phone, the intelligent watch is about to take your spot as the latest hi­tech current, allowing wearers to glance at messages and even take calls without touching their phones. The i'm Watch, available since 2011, is the flagship product of an Italian company—i'm. This smart watch is an assist to the smart phone, with which it can communicate by Bluetooth wireless technology. It means you can leave your phone in your pocket as you answer or reject a call, review e­mails or read updates from friends on Twitter or Facebook.

    The i'm Watch also has its own applications, such as i'm Sport, which links with a heart rate detector (检测器) to allow a runner to check his pulse. Such functions already exist in specialized sports watches but not on watches that are linked to smart phones.

    With a square shape, a 3.8­centimeter touch screen and various colors, the i'm Watch sells for a minimum of 300 Euros ($390) for the basic model and prices climb to 16 000 Euros for a luxury model in silver or decorated with diamonds.

    So far, the watch has already found 30 000 buyers, 80 percent of whom are men aged 25 to 50. “Seventy percent are iPhone users, 25 percent Samsung and the rest are other telephones using Google's Android operating system，” said Massimiliano Bertolini, a manager of the company, which aims to sell more than 200 000 watches this year. The company's target market is the person who is always glued to his smart phone, even in meetings or at the movies, or people who wish to keep an eye on their heartbeat during exercise. They will especially target women with advertisements emphasizing its design rather than its technology.

    Telepathy (心灵感应) is the ability to communicate without the use of the five senses. It's an instinct (本能) which can be woken up in times of emergency or need. When we feel that something is happening or about to happen by instinct, we're using resources within the unconscious mind. When the resources of two persons' unconscious minds link together into the same frequency (频率), we call it telepathy.

    We can either send or receive telepathy. If you know who is calling before you answer the ringing phone，you are probably a good receiver. If you think of a person and he/she calls you，you are most likely to be better at sending.

    You can easily put your ability to the test. Thinking of somebody and wish him or her to contact you. Be patient. The other person may not be a good receiver，but they should contact you much earlier than would normally be expected. Or whenever the phone rings，try ‘feeling' who is contacting you. Don't guess, but try to feel it with your mind. However，if neither of these works for you，that doesn't mean that you have no ability of telepathy. As mentioned earlier, telepathy is most likely to turn up in case of emergency.

    Telepathy dreams often contain telepathic messages. Two people may both dream of the other and find that their dreams have a clear connection. These people are probably linking to each other's unconscious mind.

    Telepathy & relationship. The more people spend time together, the more likely they are to be able to link up to the other's mind, especially when separated. There are two reasons for this. One is that they understand the other's mind through time spent together; the other is that there is usually a strong desire to communicate. A mother will often sense that her child is in danger. This is due to the child's eagerly wanting his or her mother, knowing that this is the person who would always want to be there for them, and the mother's deep desire to protect her child from harm.

    Feelings often run high where insects are concerned, with many people even sick when seeing them, let alone touch or swallow them. And yet insects present a huge nutritional opportunity as an increasing global population seeks more sources of food and feed.

    Insects have generally high levels of animal protein and key micronutrients with lower environmental footprints than traditional alternatives, and they can be raised on leftovers. But cultural, social and economic problems remain, reports an article published today in Nutrition Bulletin.

    “Insects present a nutritional opportunity, but it is unclear how their nutritional quality is influenced by what they are fed,” says Darja Dobermann, a researcher at the University of Nottingham. “In ideal conditions, insects have a smaller environmental impact than most traditional western forms of animal protein; less known is how to raise insect production while maintaining these environmental benefits.”

    “Studies overall show that insects could make valuable economic and nutritional contributions to the food or fed systems, but there are no clear regulations in place to bring insects into such supply systems without them turning into a more expensive version of poultry（家禽）for food,” says Dobermann.

    The article highlights how insects have been a source of food for hundreds of years in more than 100 countries with over 2,000 species that can be eaten; in central Africa, up to 50% of dietary protein has come from insects, with their market value higher than many alternative sources of animal protein.

    Insects need to be large enough to make the effort of catching them worthwhile and easy to locate, preferably in predictably large quantities. They are consumed at various life stages, as raw, fried, boiled, roasted or ground food.

    When I was 12 years old, I already knew that my teen years were going to be the worst years of my life. I was a total outsider, bullied (欺凌) at school. I felt completely alone in my small town.

    But by starting to do volunteer work when I was 14, I turned my problem into a passion for helping others. The opportunity to practice kindness made me feel like my life had a greater purpose. The more positive energy I shared, the more kindness and appreciation I received. I realized that my purpose in life would be to reach out to people, specifically teenagers, and help them feel less alone.

    Books were my true friends back then. I was so thankful that the authors wrote those books. The kindness they offered me with their books saved my life. One of my biggest dreams was to become an author so I could write books that would help other teenagers the way those books helped me.

    After surviving terrible experiences at school and at home, I made a choice to take the optimistic, positive road in the next steps of my journey. My dream career, one I thought was only possible for the authors I loved, is what I am doing now. I have been a full-time author of teen novels since 2007 and am grateful for this amazing opportunity to reach out to readers every single day.

    Kindness saved me when I needed help the most. Even small acts of kindness can change someone's life. You never know what someone else is going through. But by practicing daily kindness, you become an architect of positive change.

    I became a magician by accident. When I was nine years old, I learned how to make a coin disappear. I'd read The Lord of the Rings and risked coming into the adult section of the library to search for a book of spells (魔法) — nine being that curious age at which you're old enough to work through more than 1, 200 pages of mysterious fantasy literature but young enough to still hold out hope that you might find a book of real, actual magic in the library. The book I found instead taught basic sleight-of-hand (戏法) technique, and I devoted the next months to practice.

    Initially, the magic wasn't any good. At first it wasn't even magic; it was just a trick — a bad trick. I spent hours each day in the bathroom running through the secret moves in front of the mirror. I dropped the coin over and over, a thousand times in a day, and after two weeks of this my mom got a carpet sample from the store and placed it under the mirror to eradicate the sound of the coin falling again and again.

    I had heard my dad work through passages of new music on the piano, so I knew how to practice — slowly, deliberately, going for precision rather than speed. And then I tried the illusion (错觉) in the mirror and an unbelievable scene took place. It did not look like a magic trick. It looked like a miracle. I knew that I had got what I wanted.

    One day I made the performance on the playground. We had been playing football and were standing by the backstop in the field behind the school. A dozen people were watching. I showed the coin to everyone. Then it disappeared. The kids screamed. They yelled, laughed, scrambled away. Everyone went crazy. This was brilliant.
