      Batteries can power anything from small sensors to large systems. While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves. University of Missouri(MU) researchers are developing a nuclear energy source that is smaller, lighter and more efficient.
"To provide enough power, we need certain methods with high energy density(密度)", said Jae Kwon, assistant professor of electrical and computer engineering at MU. "The radioisotope(放射性同位素) battery can provide power density that is much higher than chemical batteries."
      Kwon and his research team have been working on building a small nuclear battery, presently the size and thickness of a penny, intended to power various micro / nanoelectromechanical systems (M/NEMS). Although nuclear batteries can cause concerns, Kwon said they are safe.
      "People hear the word ‘nuclear' and think of something very dangerous," he said, "However, nuclear power sources have already been safely powering a variety of devices, such as pace-makers, space satellites and underwater systems."
      His new idea is not only in the battery's size, but also in its semiconductor(半导体). Kwon's battery uses a liquid semiconductor rather than a solid semiconductor.
"The key part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure of the solid semiconductor," Kwon said, "By using a liquid semiconductor, we believe we can minimize that problem."
      Together with J. David Robertson, chemistry professor and associate director of the MU Research Reactor, Kwon is working to build and test the battery. In the future, they hope to increase the battery's power, shrink its size and try with various other materials. Kwon said that battery could be thinner than the thickness of human hair.
(1)、Which of the following is true of Jae Kwon?
A、He teaches chemistry at MU. B、He is working on a nuclear energy source. C、He developed a chemical battery. D、He made a breakthrough in computer engineering.
(2)、Jae Kwon gave examples in Paragraph 4 _________.
A、to introduce nuclear batteries can be safely used B、to show chemical batteries are widely applied C、to introduce various energy sources D、to describe a nuclear-powered system
(3)、Liquid semiconductor is used to _________.
A、get rid of the radioactive waste B、test the power of nuclear batteries. C、reduce the damage to lattice structure. D、decrease the size of nuclear batteries

    While dog keepers realize their dogs can read their moods accurately, scientists have always been a little doubtful. Now thanks to some researchers at the University of Veterinary Medicine in Vienna, Austria, we finally have some convincing evidence.

    For their study, biologist Corson Miller and his team exposed eleven selected dogs to digital images of women that were either angry or happy. Half the dogs were rewarded for touching the screen when shown a happy face, while the other half got their treat for selecting those that appeared angry.

    Interestingly, the dogs were not provided with the entire face. Some dogs were shown only upper halves while the others observed lower halves. That's because the scientists believe humans show their emotions on their entire face.

    After some training like how to recognize small differences like the wrinkles between the eyes or the changes in their shape that accompany the happy or angry expressions, the dogs were mostly able to identify the correct expression not only on a familiar face but on a strange face. The researchers concluded the dogs were smart enough to read human emotions.

    They also found those being trained to read angry expressions took a longer time to learn. They guess it may be because dogs find angry faces disgusting, causing them to withdraw quickly. However, once the smart dogs realized they were getting rewarded, the trepidation seemed to disappear. In fact, the dogs had such a good time playing the computer "game" that scientists had a hard time keeping them away from the touch screens after the study was completed.

    The researchers also noticed only dogs with a male owner had a harder time understanding the expressions correctly. Since the touchscreen models were all females, this confirmed what has been observed in previous studies—dogs are more efficient at reading facial expressions of people that are the same gender as their owner.

    The First Rule of Finance is to live within your means by spending no more than 80% of your take-home pay.If you take home $ 100 per week, spend no more than $80.

    But ever look at what people spend their money on? I have relatives and friends deeply in debt, spending $ 12 for every $ 10 they earn instead of the $ 8 you know they should be spending.When I see them, they're proud of their new whatever."What do you think of my new truck?" asked one from the driver's seat."Do you like my new shoes?" asked another on high heels."Check out my new big screen." said a third while holding the remote in his living room.We've all heard people fishing for compliments on their new toys

    Every one of them was proud of what they'd financed.They seem to have bought it for the purpose of being proud, of showing off, of keeping up with the Joneses."Look at my new …?"is everybody's favorite phrase, even when the object in question isn't theirs at all and won't be new when they've finally paid for it, if they ever do.

    They're proud of being stupid.They think it's cool to drive the financed car, wear the financed shoes, and watch the financed TV, but to smart people, whose opinions are the only ones we should respect, these people look dumb as rocks.

    The Joneses, nine times out of 10, are financially stupid.That's why they have all that stuff on borrowed money.Why try to copy them? Worse, why try to impress them? Copy and impress smart people, the ones who own their stuff.If you want to impress smart people, debt is the last way to go about it.Trying to impress a money-smart person by going into debt is like trying to impress Olympic swimming champion Michael Phelps by drowning in a pool.Michael Phelps is impressed by good swimming and a money-smart person by good money management.

    More and more comment(评论) sections are being shut down online.

    Autumn Phillips had had enough. On August 19, the executive editor of the Quad-City Times in Iowa, and Illinois, US visited her website, qutimes. com, and saw a story about a man who had been shot to death. When she got to the readers' comments section at the end, she was shocked by what she saw. Below the story was a growing string of comments—a racist remark about democratic( 民主的) voters, a negative comment about police...So Phillips decided to do something she had been thinking about for a long time: she shut down the comment section.

    Phillips was not alone in making such a move. Last week, NPR announced it too was closing its online comments section. The decisions don't mean that the news outlets are no longer interested in what their audiences are thinking. Both stressed their eagerness to hear from readers and listeners on social networks. But both agreed that comments had deviated from their original intention. And so they had.

    In the early days of digital journalism, comments were seen as a key part of the new media, a wonderful opportunity for strengthening the dialogue between news producers and their audiences. It was a welcome change, given that for long many news organizations were far too separated from their readers. Much more back and forth conversation seemed like healthy and welcome evolutions. Sadly, that's not the way things turned out. Rather than a place for exchanging ideas, comments sections became the home of ugly name-calling, racism and anti-women language. Besides their poisonous quality, comments seem out of place today.

    “Since we made the announcement, I've received an outpouring of responses from our readers,”she says. “I've heard from parents whose children were hurt by our online comments. I've heard from people who said they wouldn't send in letters to the editor because they were attacked so fiercely by comments, and it wasn't worth it.”

    “He is the best choice for goodwill ambassador.” Indian movie fans in China say.

    Indian actor Aamir Khan has got his major celebrity status in China. Aamir Khan was in China last week to promote his latest Hindi film Secret Superstar. During his weeklong stay, first in Shanghai and then in Beijing, the Indian actor also found out that he has become a major celebrity in a country where Hollywood's reach has been traditionally limited.

    Some local analysts compare his star status in China to that of Hollywood actors Tom Hanks, Tom Cruise and Leonardo DiCaprio. Others wonder if Khan is an activist actor. Still others describe him as a feminist(女权主义者). The Chinese media seem to have called him Mishu, or Uncle Aamir. The surprising rise in popularity of the 52-year-old Bollywood star is owing to his striking movies. At more than 1 million, Khan has the most followers as an Indian on Sina Weibo, the country's Twitter-like platform.

    Secret Superstar had made more than 400 million yuan($63 million)earlier this week. The story of a teenage Muslim girl's fight against ugly patriarchy(父权制)to realize her dreams was released in China on Jan 19.

    Last year, his film Dangal, inspired by the real journey of an Indian wrestler through a conservative landscape to turn his daughters into world-class athletes, had made nearly 1.3 billion yuan.

    In 2011, Khan's work first got major attention from Chinese moviegoers with Three Idiots, which was released in India much earlier. A statement on India's orthodox education system, similar to that of China, the Hindi film went along with the local audience. Film critics and fans alike recommended it to their friends.

    Some film critics say the education systems, gender discrimination(性别歧视)and domestic violence(家庭暴力)that Secret Superstar shows are among similarities of social issues in India and China. A series of “masterpieces” have made Khan an effective brand in China, in addition to his movie marketing and film devotion.
