Museum lets visitors walk in the shoes of a police officer
Police shows on TV are filled with high- speed car chases and crimes solved in a few minutes. But that's not a typical day for a real- life police officer. To get a more accurate picture, head to the National Law Enforcement Museum in Washington. Exhibits there invite visitors to use their senses of sight, hearing, touch and smell to gather information the way police do.
Let's look at a few exhibits.
K-9 Units
See a video of how dogs are trained to join K-9 Units. Test your ability to smell and identify various scents(气味). Learn which kinds of dogs are better at tracking bad persons while others are better at sniffing out dangerous goods.
The Web of Law Enforcement
You' ll quickly learn that crime- solving is a team effort, not only within one department, but among organizations across the country. Inspection Service is just one of the law enforcement groups helping local police when needed. For example, six organizations worked together on a national park graffiti(涂鸦) case.
Five Communities
Every community is different. Learn how the needs and challenges of five communities are being dealt with. These communities goals are to develop programs, while increasing trust between local people and police. What might work in your neighborhood? There's a place for visitors to share their thoughts.
The Training Simulator
Those aged 12 and older can try the same training scenarios(方案) and . equipment used in professional law enforcement classes in which police try to resolve difficult situations. Short videos test participants' abilities to observe accurately and think quickly before reacting.
The exercises give an understanding of what officers face on a daily basis.
" Many kids first think it's like a video game," said Alan Davis, an educator and New York police officer." They soon realize that real- life decision- making in a second isn't easy, and they freeze. For real police there are no second chances."
As far as we know batteries are playing an important role in our life. We couldn't live without batteries. Why so? Batteries provide power for 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."
Kwo n 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/ nanoelectromechanreal systems(M/NEMS). Although nuclear batteries can cause concerns, Kwon said, they are safe.
" People bear 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(晶体结构) of the solid semiconductor, Kwo n 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, Kwo n 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. Kwo n said that battery could be thinner than the thickness of human hair.
Uggs(雪地靴) are certainly ugly, or at least inelegant. The shapeless boots, pulled on in a hurry, can make anyone look like a slob(懒惰的人), which has made them the target of disrespect. It hasn't been hard to find someone strongly condemning them." Ugg boot s are no sexy," The Independent declared in 2003," unless you' re Mrs. Bigfoot on a lo ne mission across Antarctic to find Mr. Bigfoot. When wearing the boots, a writer of The Gloss complained," There's nothing to indicate that you don't have square, horrible shoeboxes in place of human feet." In 2015, one coffee shop on Brick Lane in east London ever banned ugg- wearers.
And yet, over the years, plenty of strange and unattractive shoes have met with the approval of the fashion establishment. The problem with ugg' s wasn't that they were ugly; it's that they were common.
But a funny thing happened on the way to fashion's tomb: the universal ugg has not gone anywhere. Uggs have quietly stayed here since their best time. Once you start paying attention, you' ll be shocked to discover how many people are still wearing them. They are worn by mothers in town and in the country, by teenagers on Saturday shopping trip and by people in fashion.
Perhaps the secret of uggs's unstoppable success is that, if there is a dividing line between public appeal and private style, it might be a pair of cozy boots. They are certainly comfortable, soft and warm, as if your feet were in the hugging of someone who really loves you. At$150a pair, they are neither cheap nor entirely out of range. They are casual and indulgent(纵容的).
Somehow uggs, the boots that so many people hate, have managed to challenge the cruel logic of the fashion cycle and carry on whether you approve of them or not.
Ramirez Castañeda, a Colombian biologist, spends her time in the Amazon studying how snakes eat poisonous frogs without getting ill. Although her findings come in many shapes and sizes, she and her colleagues have struggled to get their biological discoveries out to the wider scientific community. With Spanish as her mother tongue, her research had to be translated into English to be published. That wasn't always possible because of budget or time- and it means that some of her findings were never published.
" It's not that I'm a bad scientist," she says." It's just because of the language."
Castañeda is not alone. There is plenty of research in non- English- language papers that gets lost in translation, or is never translated. A research looked through more than 400, 000 peer- reviewed papers in 16 different languages and found 1,234 studies providing evidence on biodiversity conservation which, because they weren't in English, may have been overlooked. These included Japanese- language findings on the effectiveness of relocating the endangered Blakiston's fish owl, the largest owl species.
Some experts argue that for the sake of the bigger picture, scientific knowledge should converge(转换) into one common language. Science is very globalised and becoming more so, so the use of a global language is enormous for that.
Of course, scientists can work with an English partner, or use a translator- but this ultimately strengthens the cycle of dependency on the global north, leading to inequality in international influence. The specific meanings of words can also pose a problem in translation. For example, it is difficult to find in English one single word to describe forest snakes and frogs in the work Castafieda does with indigenous(土著的) communities in the Amazon.
" So we' re losing observations for science, too," says Castañeda." For me, it's not possible to just have everything translated into English. We need multilingual(多语种的) science, and we need people that feel comfortable doing science in their own languages. It could be possible to switch to a world where, say, Chinese, English and Spanish are the three languages of science, just as English, French and German were the languages of science in the 19th century."
A Few Tips for Self- Acceptance
We all want it. .. to accept and love ourselves. ___ Where do you start? Here's a handful of ways that will set you in the right direction.

It has been an unwritten rule that those who become 30 years old must have already been in a stable(稳定的) place. 1 , they might be considered a failure.
I am turning 30 tomorrow and I ask myself," Should I 2 this deadline?"I am still renting an apartment, and living alone. This seems far from 3 for most, but it looks nice to me.
When I graduated years ago, I 4 worked as a journalist because I had been dreaming of writing stories for the 5 since childhood, and I thought I would stick to it forever. But as time flies, I realize that it will be unwise to 6 myself to just one path. Therefore, I decide to start my another pursuit— studying law.
Was I 7 before? No. I have learned that there is no single formula (公式) for8 and happiness. Our lives are filled with 9 possibilities. While I really love my . current career, I have also been interested in being a 10 . So why should I11 the dream to the end just because I am 30 already?
Turning 30 can also be a chance to do whatever you like. You needn't care about how others will12 your decisions. The most important part is that you are just being yourself and13 it. Turning 30 is just like any other birthday. Stop feeling 14 about your age and try to 15 all the opportunities and surprises that life throws on your way.

Music has always been an essential part of my family. As a little girl, I often watched my mom singing with others. As I grew older, she and I would sing while we did the dishes or hung clothes. My brother Dean was also a musical soul. In good time or in bad, there was always music in our house. It shaped us, comforted us, and gave us a way to express feelings that might otherwise have gone unspoken.
After Dean became a father, we learned that his oldest son was on the autism spectrum. My nephew Carl did not handle social situations well, and sometimes even to speak aloud outside the family for him was a struggle. He worked very hard to overcome his fears, so much so that the year he was eight, he decided he wanted to be part of a music program with the other children in his Sunday school class. The part he had been offered was one that required him to sing a verse all on his own—a solo.
My brother carefully explained to him that this would mean singing in front of the audience. There would be no one singing with him. Carl considered this very carefully.After a couple of days, he decided that he would accept the part. He explained to us that he believed he could do it because it was a very special occasion. He said he knew his daddy would help him to be the best singer.
For over a month, he and his father practiced together. Every evening would find them locked away in the music room. My brother played the guitar, and my nephew's small voice came from somewhere deep down inside his little body. He gained confidence, and when the day of the concert arrived, he was certain all would go well. My brother waited backstage, giving Carl double thumbs-up, and he came out to sit with the rest of the family to watch and take photos.
Paragraph 1: When it was finally time for Carl to sing, the music played on, and he froze.
Paragraph 2: Everyone turned to see who was singing, while I knew it was my brother.
