They wear the latest fashions with the most up-to-dateaccessories(配饰). Yet these are not girls in their teens or twenties but women in their sixties and seventies. A generation which would once only wear old-fashioned clothes is now favoring the same high street looks worn by those half their age.

    Professor Julia Twiggy, a social policy expert, said,“Women over 75 are now shopping for clothes more requently than they did when they were young in the 1960s. In the 1960s buying a coat for a woman was a serious matter. It was an expensive item that they would purchase only every three or four years—now you can pick one up at the supermarket whenever you wish to. Fashion is alot cheaper and people get tired of things more quickly.”  Professor Twiggy analyzed family expending data and found that while the percentage of spending on clothes and shoes by women had stayed around the same—about 5 or 6 percent of spending, the amount of clothes bought had risen sharply.

    The professor said,“Clothes are now 70 percent cheaper than they were in the 1960s because of the huge expansion of production in the Far East. In the 1960s Leeds was the heart of the British fashion industry and that was where most of the clothes came from, but now almostall of our clothes are sourced elsewhere. Everyone isbuying more clothes but in general we are not spending more money on them."

    Fashion designer Angela Barnard, who runs herown fashion business in London, said older women were much more affected by celebrity style than in previous years. She said,“When people see stars such as Judi Dench and Helen Mirren looking attractive and fashionable in their sixties, they want to follow them. Older women are much more aware of celebrities. There's also the boom in TV programmers showing people how they can change their look, and many of my older customers do yoga to stay in shape well in their fifties. When I started my business a few years ago, my older customers tended to be very rich, but now theyare what I would call ordinary women. My own mother is 61 and she wears the latest fashions in a way she would never have done ten years ago.”

    Farah was sitting in the kitchen going over the party list with her mother. The exams were over and Farah wanted to invite her friends for a party.

    "Farah, aren't you going to invite Hafsa?" her mother asked. Hafsa had been her best friend since childhood.

    "Mother, you know I am now a part of Purple Girls Club and we have some rules about people we can be friends with," Farah answered.

    "Really? And what are the rules?" her mother asked.

    "Well, only very pretty girls can be part of our group. And Hafsa is so...you know...dark."

    "I cannot believe it," her mother said angrily.

    As Farah left the kitchen, her father called her from the living room. Farah went to her father and paled when she saw the exam report in his hands. "Farah, what has happened to your grades? You have failed in Mathematics," her father said. Farah had no answer. The truth was that the activities of Purple Girls Club left her with very little time for studies. "Farah, it says that you can take part in supplementary exams(补考). If your grades don't improve then, I'll cancel(取消) your trip to Spain." Farah went to her room and called Gina, the leader of Purple Girls Club, "Gina, can you help me to complete my notes before the exams?" Gina laughed. "Exams? Who cares about exams?"

    One by one, she called her friends in the club but no one seemed to care or wanted to help. Farah knew Hafsa would help her. Farah also knew Hafsa had been hurt by her, but Hafsa said, "If you need any help, just let me know. We can study together till your exams." Next Monday, as two friends entered the school together, Gina called out. "Farah, you know our rules. You cannot be friends with those who do not belong to our club."

    "Gina, I have a new rule about friendship," Farah replied.

    Hadi Partovi, founder of Code.org believes every student should learn the basics of computer science just like they do math, physics, or biology, regardless of what they want to do in the future. The expert says knowledge about the subject is important to understand how the world around us works and compares it to learning about photosynthesis(光合作用), even though not every student is going to be a botanist. To spark students' interest, he created the “Hour of Code,” which introduces the world of computing to anyone, from ages 14 to 104, in a fun, interactive manner. Observed annually during Computer Science Week, the event now draws tens of millions of kids from over 180 countries.

    The “Hour of Code”, which can be scheduled anytime during Computer Science Week, begins with an introductory video on computer science. Participants can then select from hundreds of fun assignments that are sorted by both grade level and coding experience. Though each project is designed to last just sixty minutes, beginners can deal with as many challenges as they desire.

    To help introduce computer science in classrooms on a more regular basis, Code.org has also developed a catalog of online courses that can be incorporated(纳入)in a school's regular curriculum. Since the nonprofit began offering the courses in 2013, over 704, 000 teachers have signed up to teach introductory computer science to over 22 million students worldwide.

    Thanks to the efforts of the pioneer, about 40 percent of US schools now offer computer science as a subject. The numbers are even higher—an impressive 70 percent—if after-school offerings such as robotics clubs are included. Even more encouraging, eight years ago, just 19, 390 students took an Advanced Placement Computer Science exam. By the spring of 2017, the number had jumped 415 percent to 99, 868.

    Last year, when our three-year-old great-granddaughter Kylie was taken to see Santa Claus, she made sure to give him her wish list of toys. A week later, she ran into a different Santa in a mall. He stopped to ask what she wanted for Christmas. Kylie was surprised and let him know: "If you can't remember what I told you last week, how are you going to remember on Christmas Eve?!"

    As my son Mike and I drove to the mall, we passed a Salvation Army Santa ringing his bell. "Mike," I said, "there's Santa!" He shook his head. "That's just some guy in a Santa suit," he said. It saddened me to think that maybe my son no longer believed in Santa, and we drove the rest of the way in silence. At the mall, we spotted another Santa greeting young believers. Suddenly, Mike took off toward him. Turning back to me, he shouted. "Now, there's the real Santa!"

    We immigrated to America from China when I was six. Because I was shy and didn't speak English, I had few friends. My days were spent at home with my brother. Sometimes we'd help our neighbor Mr. Mueller pull weeds. One Christmas Day, there was a knock at the door. Grandma opened it, and there stood a big fellow in red with a snow-white beard, laughing, "Ho, ho, ho!" He handed out presents and made us laugh. I had so much fun. It was years later when I learned that our special Santa was our neighbor Mr. Mueller.

Video calls are a common occurrence, but have you imagined being able to touch the person on the other end of the line? Scientists are making this a reality.

Researchers at the University of new South Wales, Australia have invented a soft skin stretch device (SSD). A haptic device that can recreate the sense of touch. Haptic technology mimics the experience of touch by stimulating localized areas of the skin in ways that are similar to what is felt in the real world, through force, vibration or motion.

Vibration is the most common haptic technology today and has been built into many electronic devices such as one attached to the back of the trackpad (触摸板) in laptops, which simulates a button clicking. However, haptic feedback with vibration becomes less sensitive when used continuously. The existing technology also has great difficulty recreating the sense of touch with objects in virtual environments or located remotely. According to Mai Thanh Thai, lead author of the study.

The new technology overcomes issues with existing haptic devices. The research team introduced a novel method to recreate the sense of touch through a soft artificial "muscles".

"Our three-way directional skin stretch device, built into the fingertips of the wearable glove we also created is like wearing a second skin-- its soft stretchable and mimics the sense of touch-- and will enable new forms of haptic communication to enhance everyday activities" said Thanh Nho Do, senior author of the study.

Imagine you are at home and you call your friend who is in Australia. You wear a haptic glove with the SSDs, and your friends also wears a glove with integrated 3D force sensors. If your friend picks up an object, it will physically press against your friend's fingers. And their glove with 3D force sensors will measure with interactions. The force signals can be sent to your glove so your device will generate the same 3D forces. Making you experience the same sense of touch as your friend.

The haptic devices could be applied in various situations, allowing users to feel objects inside a virtual world or at a distance. It could also be used in medical practices. Doctors can feel a patient's organ tissues. With surgical tools without touching them.

The reopening of an Asian American-owned bookstore in Manhattan's Chinatown following a January fire has received a warm welcome back from its supporters.

Yu &. Me Books, which is regarded as the first female-owned Asian American bookshop in New York City, has raised more than $369,000 for repairs since a tragic fire on January 4. It reopened on Wednesday. "We are so excited to welcome you all back to our Yu &. Me Books home," the store announced on Instagram. "We can't wait to shed tears, laugh loudly and open our hearts with all of you who have made us feel at home."

The fire in an apartment above the bookstore on Mulberry Street killed one of the building's residents. Smoke and water damage also devastated Yu & Me Books, destroying almost all its inventory and equipment, according to a GoFundMe campaign that store owner Lucy Yu set up to make up for the costs.

During the restoration and renovation (翻新) of the original bookstore, the business operated from a location within The Market Line, an underground marketplace on the Lower East Side, and several pop-up shops (临时店铺) in the city.

"It was a bookstore I always wanted to visit, and I'm so happy that they were able to reopen," Charlotte Leinbach, a teacher for New York City's Education Department said. Leinbach hadn't been to the bookstore before the fire, but she had heard quite a bit about its fate. She bought two books, the second and third in the series Before the Coffee Gets Cold.

"It's hard to find a lot of books written in Japanese, and then translated into English," she said. "The design of the bookstore is really nice, and the layout is great. I am glad that they also sell used books. I love buying new books because it's fresh and it's nice, but it's always nice to see people in the community giving their books back and reselling and just passing them on." She said she will continue to support the women-run small businesses that focus on people and authors of color.

"I actually came on the day of the opening, but there were too many people, and it was too crowded, so I just haven't had a chance to look at it," Liam Li, another Asian American, said. "This place is unique. It's in Chinatown. As Asians live in New York City, I feel this offers the most space for the community. I understand like a minority in this society, it is not easy to have a store like this," she added.
