As traditional Chinese art, paper cutting has a long history. The first and earliest paper cutting was found in China 1,500 years ago. But this traditional art is at risk of disappearing now. Luckily, Vivian Woo, a Chinese immigrant in America, is trying to bring this art back to life.

    One Saturday in 2017，Ms. Woo held a paper cutting show at a shopping center near Washington. She got much fun and peace doing it. She hoped more people would enjoy it. Ms. Woo began to study the art of paper cutting as a 14 - year - old girl in her hometown in China. She said all the students at school had to learn paper cutting. But she had a deep love for it. So her teacher spent more time teaching her after class. Later, she won the second prize in a national painting and art competition. Ms. Woo went to America after she finished college in 2008. Soon after that, she took part in an activity to promote Chinese paper cutting. And then she was invited to show the art in many important activities. “It is important to promote this art to Americans or anyone who is interested in it. Maybe it will make this art more popular.” Woo said.

From the art of paper cutting, people can know about Chinese cultural values, history and stories of people's life. Ms. Woo uses the art as a tool to show Chinese culture to people who know little about it. Chinese art is not only for Chinese, but also for people ail over the world.

    Rapid advances in a new technology will soon transform science fiction into reality — meaning people will have driverless cars, small robots at their command and the ability to experience being in another place without leaving home, predicted Google executive chairman Eric Schmidt at the Mobile World Congress in Barcelona, the planet's largest cell phone trade show.

    Introduction of books available online, Internet translation of languages and voice recognition for computers all happened much faster than anyone could foresee and that technological research into even more previously unheard of advances is progressing at a fast speed.

    “People who predict that holograms（全息图）and self-driving cars will become reality soon are absolutely right,” Schmidt told thousands of attendees. Research under way will lead to situations where people can put themselves at events like a rock concert so that they can see, hear and even feel the event. And turn down the volume, if it's too loud.

    One attendee said she was scared that the possibility could be dehumanizing, but Schmidt replied by holding up his cell phone into the air. “It has an off button and it is here on the right,” Schmidt said. “My point is that it is all about your control. If you don't like my version of a rock concert, I'm not forcing you to go.” In the future, small robots could be used so busy people can send them to events for video and voice transmissions when their presence isn't required, Schmidt said.

    Technology in the near future will redefine the relationship among people in the world. “With technology comes power and with power comes choice, and smarter resourceful citizens are going to demand a better deal for their new life,” Schmidt said.

    It was the last time Susan Butcher ran the Iditarod Trail Sled Dog Race in 1992. An hour into the race, Susan and her sled dog team sped down a hill and crashed into a fallen tree. Although hurt, Susan continued the difficult race.

    The Iditarod Race started in 1925 when a doctor in Nome, Alaska was desperately in need of medicine to stop the spread of a deadly disease. Only a hospital had what he needed, but it was 700 mile-away! In January, it was too dangerous to send a boat and too stormy for his tiny airplane. The only hope was to use several sled dog teams following a trail, called the Iditarod Trail. They passed the medicine from one sled team to another. Wind and snow did not stop the men and their dogs. The medicine was delivered in record time. The race follows the route of the famous medicine run. Over 1,000 miles long, it is considered the toughest race in the world.

    Susan Butcher was born in Cambridge, Massachusetts. In her teens Susan was given a Siberian husky dog and became very interested in huskies as sled dogs. After reading about the Iditarod Race, Susan moved to Alaska. She got several jobs to earn money to buy herself a sled and a team of huskies. After years of hard work and training, Susan achieved her dream of racing on the Iditarod Trail.

    In 1978, at the age of 24, Susan entered the race for the first time and became the first woman to finish in the top 20. In 1982 she came in second. In 1984 she was leading her team across a frozen waterway when they fell into the water. Her lead dog managed to pull Susan and the other dogs out of danger. Remarkably, she came in second.

    In her fourth race, in 1985,a starving moose(驼鹿) attacked her dogs, killing two and injuring eleven. Susan had to leave the race. In 1986 Susan joined the race again. This time, she won. She won again in 1987. In 1988 she became the first person ever to win three Iditarod races in a row. Unbelievably, Susan won for the fourth time in 1990.

    Since the 1970s, scientists have been searching for ways to link the brain with computers. Brain­computer interface (BCI) technology could help people with disabilities send commands to machines.

Recently, two researchers, Jose Millan and Michele Tavella from the Federal Polytechnic School in Lausanne, Switzerland, demonstrated(展示) a small robotic wheelchair directed by a person's thoughts.

    In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand. He could even talk as he watched the vehicle and guided it with his thoughts.

    "Our brain has billions of nerve cells. These send signals through the spinal cord(脊髓) to the muscles to give us the ability to move. But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles." Tavella says. "Our system allows disabled people to communicate with external world and also to control devices."

    The researchers designed a special cap for the user. This head cover picks up the signals from the scalp(头皮) and sends them to a computer. The computer interprets the signals and commands the motorized wheelchair. The wheelchair also has two cameras that identify objects in its path. They help the computer react to commands from the brain.

    Prof. Millan, the team leader, says scientists keep improving the computer software that interprets brain signals and turns them into simple commands. "The practical possibilities that BCI technology offers to disabled people can be grouped in two categories：communication，and controlling devices. One example is this wheelchair."

    He says his team has set two goals. One is testing with real patients, so as to prove that this is a technology they can benefit from. And the other is to guarantee that they can use the technology over long periods of time.

Beethoven is a giant of classical music. And the most influential, too—at least, when it comes to piano compositions. That's according to a study in the journal EP J Data Science.

If you're wondering how data analysis could determine something as abstract as cultural influence, it's worth remembering this: Music is the most mathematical of the art form, a lot of which is symbolic. The music is written in symbols that are connected in time.

Juyong Park is a theoretical physicist in South Korea. Park and his colleagues collected 900 piano compositions by 19 composers from 1700 to 1910. Then they used that mathematical quality to their advantage by dividing each composition into what they called "code words", in other words, a chord. They then compared each chord to the chord or note that came after it, which allowed them to determine how creative composers were at coming up with novel transitions.

The composer with top marks for novelty was Rachmaninoff. But when the researchers looked at those chord transitions across all 19 composers, it was Beethoven who was most heavily borrowed from—meaning at least among the composers in this analysis, his influence was the largest.

Their study comes with some drawbacks. For example, the researchers only considered piano compositions in this work, and by only studying chord transitions, so their conclusions wouldn't relate to artists who were influential in other ways like Bach or Mozart. Park explained, "It's well understood that Mozart's contribution to music comes from the musical forms that he designed. That was not very well reflected by our mathematical modeling."

As for Park, the results convinced him he has some listening to do. "Of course I listen to music. I like Rachmaninoff's music, but I have to say I have listened to Beethoven way more than Rachmaninoff. So after this work came out, I ended up buying his whole complete collection.
