Here's an idea whose time has come: A flu shot that doesn't require an actual shot.

    For the first time, researchers have tested a flu vaccine patch (疫苗贴) in a human clinical trial and found that it delivered as much protection as a traditional injection with a needle. Doctors and public health experts have high hopes that it will increase the number of people who get immunized (免疫的) against the flu.

    Seasonal flu is responsible for up to half a million deaths around the world each year according to the World Health Organization. A team led by Georgia Tech engineer Mark Prausnitz has come up with an alternative method that uses “microneedles”. These tiny needles are so small that 100 of them, arranged in order on a patch, can fit under your thumb (拇指).Yet they're big enough to hold vaccine for three types of flu.

    None of the study volunteers had serious side effects. The groups that got patches had mild skin reactions that were not seen in the regular needle group, while the volunteers in the regular needle group were more likely to experience pain. Overall, 70 percent of the volunteers who got vaccine patches said they'd rather use them again than get a traditional flu shot. The study authors declared it a success on all fronts.

    The biggest beneficiaries could be people in low- and middle-income countries, where flu vaccines are hard to come by. Reducing pain is nice, but other benefits—the patch costs less，is easier to transport, doesn't require refrigeration, can be self - administered and doesn't cause waste of needles—are even better.

    “Microneedle Patches have the potential to become ideal candidates for vaccination programs,” wrote Katja Hoschler and Maria Zambon of Public Health England.

    Have you ever noticed what happens to an idea once you express it? Just talking about it or writing it down causes you to make it clear in your own mind. How can you use this to increase your brain power? Start writing.

    By putting thoughts into words, you are telling yourself the logic (逻辑) behind what you think, feel, or only partly understand. Often, explaining a thought is the process of understanding. In other words, you increase your brain power by exercising your “explain power.”

    Try this experiment. Explain how you'll increase your brain power, even if you have no idea right now. Just start with anything, and create an explanation. For example, start with “I'll learn chess,” or “I'll read an article on the mind every week.” Explain how that will help. You'll be surprised how often this becomes a workable plan, and if you actually do this, you'll have a better understanding of your brain from now.

    Another benefit of writing is that it helps you remember. Many, if not most, highly productive people are always taking notes. You can try keeping it all in your head, but if you keep a journal of your ideas the next time you're working on a big project, you'll probably have more success.

    Want to understand a topic? Write a book about it. That's an extreme example, but if you are learning something new, write a letter to a friend about it, and you will understand it better. Want to invent something? Write an explanation of the problem, why you want to solve it, and why it is worth solving, and you're half-way there.

    Writers don't always write because they clearly understand something beforehand. Often, they write about something because they want to understand it. You can do the same. Writing will help bring you to an understanding. Give it a try.

    Red leaves are a symbol of autumn. Enjoying red leaves in the clear, refreshing autumn weather is indeed a good choice.

    Now let's have a look at the best red leaves around China and the beauty of autumn.

    Destination 1

    With different red colors, the Red Leaf Valley extends (延伸) more than 50 kilometers from Jiefang village in Qingling town to Yanjiang village in Songjiang town, Jilin province, Northeast China. Leaves are like different red pigments (颜料), including Chinese red, orange red, ruby red and bright red.

    Best time: October

    Destination 2

    Tachuan or Tashang village is in Huangshan city, Anhui province, East China. The beautiful autumn scenery there is known as one of the four best in China. The red leaves and clear spring add beauty to traditional houses, offering material for photography lovers.

    Best time: early to late November

    Destination 3

    As a result of low temperatures, maple leaves in areas south of the Yangtze River are like shy girls, gradually showing their beauty, turning from green to gold, gold to orange and finally to red. And as it changes slowly, different colors can be seen on the same trees called "colorful maple trees". Viewing at the mountainside is the best choice.

    Best time: October to November

    Destination 4

    For Guangdong province in South China, autumn always comes a little late and lasts longer. Through the end of January, you can see the red leaves any time you want. If you feel pity at saying good-bye to red leaves in North China, you can head to South China to view the beautiful scenery again.

    Best time: end of November to end of January

Every day, as I took long walks through North Vancouver, I would think about the potential joys of a physically closer network. Wouldn't it be great to have someone who could join me at a moment's notice? How good would it be to have more non-scheduled hangs instead of ones that had to be planned weeks in advance?

This doesn't have to be just a dream. Although technology is making it easier to maintain long-distance connections nothing can replace seeing friends in person. Researchers have found that happiness spreads "like an emotional contagion (传染)", especially among those who live close together.

Friends who live in the same city could decide to move within walking distance of one another — the same neighborhood, block, or even apartment building. Doing so would likely involve a lot of effort, but the resulting community could pay emotional dividends for years. Doing so would make it easier to support one another materially and emotionally.

Moving close to your friends requires some masterminding. Cities can make doing so easier by ending single-family zoning codes and encouraging a variety of housing types in neighborhoods. But even without official policies, people can make it work on their own. Sam Unger, 32, a food scientist and a friend of mine, has created a chosen family like this in Montreal, where about 15 of her friends live within walking distance of one another. When someone moves away, they try to transfer (移交) their lease (租约) to other friends. And when pals based elsewhere in the city are looking to move, Unger will try selling them on the positives of her neighborhood and sometimes even look for housing for them. "It's funny," she told me. "The other day, I bought a fire extinguisher, and she's like, ‘Oh, well, I have one. You could just call me if you had a fire, and I'd be right over with it.'"

Every New Year, thousands decide they're going to change their lives. Fewer than 10 percent actually stick with their plans, and that figure is being generous. {#blank#}1{#/blank#}.

Not aiming high enough. While it's easy to think setting easy goals will keep you motivated, it may harm your long-term motivation. If you make goals that are too achievable, you'll get bored and lose interest. {#blank#}2{#/blank#}. If you're used to staying within your comfort zone, you'll be missing out on the satisfaction of achieving a life-changing goal. When you push yourself, you'll be able to build unshakable confidence as you achieve goal after goal.

{#blank#}3{#/blank#}. This is a fear many of us deal with. Instead of taking action, we start worrying about " What if?" "What if it doesn't work out? What if my dream isn't truly my dream? What if I don't succeed?" If you have trouble creating a vision , then you're at the risk of being aimless through life. {#blank#}4{#/blank#}. You can start the process of discovering your life purpose by asking yourself, " What would my ideal life look like?"

Letting fear control your mind and actions. Fear can prevent you from achieving your dreams. You'll miss out on opportunities in life if you don't learn how to manage your fears. {#blank#}5{#/blank#}. One way to manage fear is to look for the root cause of your fear. With deep introspection (反省), you can uncover the exact moment when those fears are holding you back from growing. This will give you a window of opportunity to communicate with your inner being and find release.

A. Lacking self-confidence

B. Being uncertain about the future

C. Fortunately, fear can be overcome

D. Below you'll find some common reasons why you're losing motivation

E. Many of us are motivated not by a desire to achieve, but by fear of failure

F. Ideally, you want to strike a balance between pushing yourself and creating realistic goals

G. However, when you find your purpose and passion, you'll be driven to struggle for excellence
