3 . At the Smithsonian Folklife Festival, among mountain songs and ethnic costumes and special ceremonies, I am noticeable despite my modern dress, as my green “VOLUNTEER” nametag brands me as a perfect target for curious tourists. I have volunteered to learn about global customs; my knowledge of my native culture is limited. I had boxed up my past before moving to America eight years ago, when a new continent considered my old self foreign.

Here on the National Mall, I am the only means of communication between the Americans and the artisan (工匠), who were invited from China to display their talents. They see my awkward hand gestures as I test my mother tongue, speaking Mandarin (普通话) and putting it into English for visitors.

The artisans possess exceptional skills. He Guoyao can read thousands of pictographic characters (象形文字) and bears the duty of passing on Dongba culture. Cheng Zhirong creates fantastic animal figures with a spoon and melted sugar in minutes. Standing among them, I wonder about the contributions a 16-year-old girl can make.

“Ooh, it’s so pretty!” A young girl sticks her nose close to a sugar dragon. Zhirong, the candy maker, signals to me, and I explain to the girl that the dragon is pure sugar. “Mommy, it’s candy!” she excitedly says. “Beautiful...” The crowd breathes in awe. One woman taps me on the shoulder, saying, “Please, tell her that her work is surreal... a gift from another world.”

As Zhirong takes my hand and calls me “little sister”, I find my place in this group of extraordinary people who crossed oceans to build a bridge between different ethnicities and nationalities through sugar sculptures and painted words. I, too, am a bearer of traditions．

I smile at Guoyao, as he paints in pictographic characters the English words I have taught him, “You’re welcome.” I come to know that culture is not shelved behind glass cases in museums. It is in the life that I once thought backward and dull — the Chinese way of life that is a part of me.

4 . 4 places in the Midwest that look like they could be in Europe

If an expensive overseas trip isn’t in the cards for you right now, don’t worry. Take a road trip from Chicago and check out these Mid-western tourist spots that look like they’re straight out of a European postcard．

★Niles, Illinois

If you visit a square at 6300 W. Touhy Avenue, you’ll find a pleasantly European surprise — a half-sized copy of the Leaning Tower of Pisa. Constructed in1934 to hide a water tower, the Leaning Tower of Niles stands 94 feet tall with a 7. 4-foot tilt which looks like the Italian one．

★Lindsborg, Kansas

Originally settled by Swedish immigrants, Lindsborg’s Scandinavian culture remains clear through public art and Swedish specialty shops, so prepare to collect Scandinavia n clothes, cookies, and wine. Best of all are the town’s yearly Scandinavian celebrations, where you’ll find various Swedish traditions．

★Frankenmuth, Michigan

Lovingly called “Little Bavaria”, this central Michigan town look like they’ve been transported straight out of a Franconian village. For the full Bavarian experience, you can stop by one of its restaurants for traditional German food. You can also learn a little more about the town’s Franconian origins．

★New Glarus, Wisconsin

Many people in Chicago know New Glarus for its brewery. Take a walk there and you’ll soon realize why it’s called “Little Switzerland”. Named after the big city of Glarus in Switzerland, New Glarus’ wooden houses, Swiss restaurants and museums, and gently hilled landscapes make for an almost Alpine（阿尔卑斯山的）experience．

6 . Great Places to Enjoy Books

Sinan Books offers a space for learning and thinking to the general public living in the city. Its door has red decoration, showing Sinan Books’ attitude of openness, and its reading space is beautifully decorated with yellow lights. The color green sets off the exhibition spaces. Spaces on the fourth floor are decorated with black and white colors to encourage readers to face themselves.

As the name suggests, it’s a city of books. The bookstores make lots of book lovers come here. In particular, the yearly Booksori book festival attracts nearly one million visitors. At the festival, the organizers present Paju Book Awards to the great Asian writers, editors, and designers. Besides, you can give your old books in return for those books you want to read in these bookstores. The most popular bookstore is Bomulseom, which carries a quality selection (挑选) of Korean, English, and Japanese books, as well as magazines and albums.

Bonjinsha is a bookstore dedicated to (致力于) the teaching and learning of the Japanese language. The store in Tokyo has a wide variety of teaching materials for all levels, from beginners to advanced learners. If you are studying or living in Japan and need to improve your Japanese language skills, then Bonjinsha will be a good place to start. Not only is Bonjinsha an established bookstore, but it’s also a famous publishing house in Japan.

Although it is only 0.9 km long, there is a range of bookstores and publishers right on the street. Perhaps the most well-known bookstores in this neighborhood are Dasgupta & Co., the first bookstore on College Street founded in 1886 with a large number of rare books, and the Bani Library, a family-run business for five generations housing all kinds of textbooks related to all things academic.

8 . Researchers have proposed a novel method for counting and tracking vehicles on public roads, a development that could improve current traffic systems and help travelers get to their destinations faster.

Using the cameras already installed on campus buses at the Ohio State University, researchers proved that they could automatically and accurately measure counts of vehicles on urban roadways, detect objects in the road and distinguish parked vehicles from those that are moving.

In previous studies, Ohio State researchers found that using these mobile cameras provides much better spatial and temporal (时间的) coverage than relying on often temporarily placed sensors that don’t provide a view of many streets and roads in a city.

“If we collect and process more high-resolution (高清) spatial information about what’s happening on the roads, then planners could better understand changes in demand, effectively improving efficiency in the broader transportation system,” said Keith Redmill, lead author of the study.

“If we can measure traffic in a way that is as good or better than what is conventionally done with fixed sensors, then we will have created something incredibly useful extremely cheaply,” he said. “Our goal is to start building a system that could do this without much manual intervention because if you want to collect this information over lots of potential vehicles and lots of time, it’s worth fully automating that process.”

While still a long way from total implementation (实施), the study suggests the system’s results bear promise for the future of intelligent traffic surveillance. Transportation planners, engineers and operators make vital decisions about the future of our roadways, so when designing transportation systems to work over the next 30 to 50 years, it’s necessary that we give them data that allows them to improve the efficiency of the system and the level of service provided to travelers.

9 . With a fragrance (芳香) through the bedrooms of older adults for two hours every night for six months, memories skyrocketed. Participants in this study by University of California, Irvine (UCI)neuroscientists gained a 226% increase in cognitive capacity compared to the control group. The researchers say the finding transforms the long-known tie between smell and memory into an easy, non-invasive technique for strengthening memory and potentially preventing dementia (痴呆).

The project was conducted through the UCI Center for the Neurobiology of Learning & Memory. It involved men and women aged 60 to 85 without memory impairment. All were given seven small containers, each containing a single and different natural oil. People in the enriched group received full-strength oils. Control group participants were given the oils in tiny amounts. Participants put a different container into their room each evening prior to going to bed, and it activated for two hours as they slept.

People in the enriched group showed a 226% increase in cognitive performance compared to the control group, as measured by a word list test commonly used to evaluate memory. Participants also reported sleeping more soundly. The researchers say the results from their study bear out what scientists learned about the connection between smell and memory.

Scientists have long known that the loss of ability to smell, can predict development of nearly 70 neurological and psychiatric diseases. These include Alzheimer’s and other dementias, Parkinson’s and alcoholism. Researchers have previously found that exposing people with moderate dementia to up to 40 different smells twice a day over a period of time improved their memories and language skills, eased depression and improved their sense of smell.

The team would next like to study the technique’s impact on people with diagnosed cognitive loss. A product based on their study and designed for people to use at home is expected to come onto the market this fall.

10 . For many runners, a marathon can often be a challenge — but sometimes what gets a runner through the tough 26.2 miles is looking out into the crowd and seeing his or her loved one holding up a sign and shouting words of encouragement. For one mom, though, her loved one was a bit more hands-on.

While running the REVEL Big Cottonwood Marathon in Salt Lake City, Courtney Rich, a self-taught baker and mother of two, was beginning to run out of energy just yards from the end when she was suddenly joined by her 10-year-old daughter, Avery.

The touching moment, caught on video and posted on social media, shows Avery running to her mother’s side to support her as she approached the end of the race. Rich’s face lit up when Avery joined her and helped her cross the finish line.

Rich later said in the video’s caption that being joined by her daughter to finish the race was “a moment I hope neither of us ever forget”. Rich said that her daughter could tell she was struggling after a phone call near the end of the race. “She knew I had struggled the last few miles,” Rich said. “She saw tears in my eyes when I called on mile 24.”

In the video, Rich’s facial expression changes from tiredness to a smile after seeing her daughter emerge from the crowd to join her. Then, Rich and her daughter ran hand-in-hand to the finish line. “Nothing could have prepared me for the moment my 10-year-old daughter would jump out of the crowd and run with me to the finish line,” she said. When the race was done, the two hugged each other at the finish line. The video ends with a final caption, “And then she just held me. She held me.”

In the past, the REVEL Big Cottonwood Marathon has had other memorable moments of mothers caring for their children, but perhaps not as hands-on as this one.
