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.

    Persuasion is the art of convincing someone to agree with you. According to the ancient Greeks, there are three basic tools of persuasion : ethos, pathos, and logos.

    Ethos is a speaker's way of convincing the audience that she is trustworthy, honest and reliable. One common way a speaker can develop ethos is by explaining how much experience or education she has in the field. After all, you're more likely to listen to advise about how to take care of your teeth from a dentist than a fireman. A speaker can also create ethos by convincing the audience that she is a good person. If an audience cannot trust you, you will not be able to persuade them.

    Pathos is a speaker's way of connecting with an audience's emotions. For example, a politician who is trying to convince an audience to vote for him might say that he alone can save the country from a terrible war. These words are intended to fill the audience with fear, thus making them support him. Similarly, an animal charity might show an audience pictures of injured dogs and cats, to make the viewers feel pity. If the audience feels bad for the animals, they will be more likely to donate money.

    Logos is the use of facts, statistics, or other evidence to support your argument. An audience will be more likely to believe you if you have convincing data to back up your claims. Presenting this evidence is much more persuasive than simply saying “believe me”.

    Although ethos, pathos, and logos all have their strengths, they are often most effective when used together. Indeed, most speakers use a combination of ethos, pathos, and logos to persuade their audiences. So, the next time you listen to a speech, watch a commercial, or listen to a friend try to convince you to lend him some money, be on the lookout for these ancient Greek tools of persuasion.

    If you could have one superpower, what would it be?

    Dreaming about whether you would want to read minds, see through walls, or have superhuman strength may sound silly, but it actually gets to the heart of what really matters in your life.

    Every day in our work, we are inspired by the people we meet doing extraordinary things to improve the world.

    They have a different kind of superpower that all of us possess: the power to make a difference in the lives of others.

    We're not saying that everyone needs to contribute their lives to the poor. Your lives are busy enough doing homework, playing sports, making friends, seeking after your dreams. But we do think that you can live a more powerful life when you devote some of your time and energy to something much larger than yourself. Find an issue you are interested in and learn more. Volunteer or, if you can, contribute a little money to a cause. Whatever you do, don't be a bystander. Get involved. You may have the opportunity to make your biggest difference when you're older. But why not start now?

    Our own experience working together on health, development, and energy the last twenty years has been one of the most rewarding parts of our lives. It has changed who we are and continues to fuel our optimism about how much the lives of the poorest people will improve in the years ahead.

    There was a time in the 1960's and 1970's when some people believed that coffee would replace tea as Britain's favourite drink, but that did not happen, and today, tea remains Britain's favourite drink.

    To say that the British are fond of tea is something of an understatement. From the Royal(皇室的) Family down to the homeless and the out-of-work, tea is more than just a pleasure. It is an important part of life!

    The popularity of tea in the United Kingdom has a long history. It was in 1657 that Thomas Garway, the owner of a coffee house, sold the first tea in London. The drink soon became popular as another choice besides coffee.

    In those days, however, tea was not something for anyone. For a century and a half, it remained an expensive drink. Many bosses served a cup of it to their workers in the middle of the morning, thus inventing a lasting British tradition, the “tea break”. But as a social drink outside the workplace, tea was served for the nobility(贵族) and for the growing middle classes. Among those who had the money for tea, it became very popular as a drink to be enjoyed in cafés and “tea gardens”.

    It was the 7th Duchess of Bedford who, in around 1800, started the popular “afternoon tea”, which took place at about four o'clock. At about the same time, the Earl of Sandwich popularized a new way of eating bread with something (e. g. jam) between them, and before long, a small meal at the end of the afternoon with tea and sandwiches had become part of a way of life.

    As tea became much cheaper during the nineteenth century, its popularity spread right through British society. In working-class households, it was served with the main meal of the day, eaten when workers returned home after a day's labour. This meal has become known as “high tea”.

    Today, tea can be drunk at any time of day. Most people in Britain drink tea for breakfast. The mid-morning “tea break” is an institution in British offices and factories. Later in the day, “afternoon tea” is still a way of life in the south of England and among the middle classes, while “high tea” has remained a tradition in the north of Britain.

    Studies show that older people tend to remember the positive things in life rather than the negative things, while younger people remember the positive and negative equally well. The dominant psychological theory to explain this is that older people are aware of their limited time left, so they prioritize positive emotional experiences. But about a decade ago, I worked with biologist Robert Trivers on his idea that there was an evolutionary basis for older people's increased positive outlook. Our research took us in the fascinating direction of exploring how the body uses its energy.

    When our ancestors needed more energy than usual, perhaps while being chased by a tiger, they had to get that energy from somewhere in the body. Could they borrow it from the brain? That organ uses 20 percent of our metabolic (新陈代谢) output, whether we are solving math problems or watching television reruns. Due to this constant energy requirement, borrowing energy from the brain when our need surpasses the available supply is not an option. Perhaps we could borrow energy from our muscles. Because we use far more muscle energy when we are active than when at rest, in principle, we could borrow energy when we are sitting. But the problem is that most of the energy-demanding emergencies of our ancestors required a muscular response. There was no way to borrow energy from our muscles during an emergency because relaxing when a tiger showed up was not an effective response. This brings us to our immune system, which, when strong, protects us from many illnesses and diseases. Like the brain, the immune system works at great metabolic cost, but largely in the service of keeping us healthy in the future. We have an enormous number of immune cells coursing through our body, a momentary break from production is fine. So, when our body needs extra energy, one of the places it goes is our immune function. When you're being chased by a tiger, you don't need to waste energy making immune cells to fight off tomorrow's cold. What you need is to shift all available energy resources to your legs, with the hope that you will live to experience another cough or sneeze.

    As a result, our immune system evolved to run in maximum amounts when we're happy, but to slow down dramatically when we're not. With this background in mind, Trivers supposed that older people evolved a strategy of turning this relationship on its head, becoming more focused on the positive things in life in an effort to enhance their immune functioning. This was helped along by their knowing much more about the world than younger adults, so they can deal with some of the unpleasant things in life more easily.
