1 . The use of AI (artificial intelligence) is becoming more common in many branches of industry and online shopping. Traditional lines of work, such as goods transport and driving, are developing in a similar direction although mainly out of public view. Scientists at the University of Göttingen have now investigated how efficient (高效的) the use of AI can be in the commercial management of trucks.
“Digital applications—as well as machine leaning, a kind of AI—are increasingly applied to operations and courses in the transport area,” explains Professor Matthias Klumpp from the Faculty of Economics. “The question in the commercial area, however, is whether or not this contributes to achieving goals.”
To answer this question, the researchers compared the work efficiency of truck drivers with their main use of AI applications. Looking at trade delivery by truck, they studied three groups: the first drove completely following human decision-making models; the second used a combination of human and machine; and the third depended completely on fully automated decisions.
The researchers found that an intelligent combination of human work and decision-making abilities with AI applications promises the highest transport and driving efficiency. “On average, the second group achieved the most efficient transport trips, with the fewest interventions (干预) and off-course from the best path.” one researcher said, “Clearly, neither a completely human decision-making structure nor a fully automated driving system can promise to meet current goods transport requirements.” The scientists therefore summarized that despite the progress of AI in the field of transportation by truck, human experience and decision-making abilities will still be necessary in the longer term. However, the challenge is that a wide range of training and qualification (资格) needs will come along by working with Al applications, especially for simple goods transport activities.

2 . In the world of Chinese archaeology (考古学), a sign of a dig's importance is the sight of Zhou Mingsheng at work. A field technician who has worked at archaeological sites all around China. Master Zhou is credited with the gentlest touch in his profession. Born into a farming family, he is a “national-level craftsman” with a talent for using simple tools to get relics (遗物) that would crumble in other hands, says his current boss, Wang Xu, director of an archaeological site at Shuanghuaishu, a Neolithic (新石器时代的) settlement near the Yellow River in the central province of Henan.
It is not beauty that attracts visitors to Shuanghuaishu. At 5, 300 years old, the settlement is the work of a culture too simple to have left behind many buried treasures. The single most precious find, to date, is a finger-length sculpture of a silkworm. Nor is the setting lovely: an area surrounded by deafening insects, between a highway and two power stations. Rather, the site's importance is historical. For since the birth of Chinese archaeology in the 1920s, it has been inseparable from claims that China has the oldest unbroken civilisation on Earth.
Leading archaeologists say that the site has the right combination of location, age and distinctive cultural elements to be the capital of an early Chinese kingdom. That would make it a bridge between China's written history and the era of the Yellow Emperor, who is said to rule over these central plains almost 5,000 years ago, though many foreign scholars doubt his existence. Chinese media call the site proof of China's 5,000 years of history.
Foreigners complain about a lack of written records, Mr Wang notes. Perhaps they are missing symbols that will one day be understood, for instance in patterned pottery. Outsiders "can't keep using Western standards to apply to Chinese ruins," he argues.

3 . The winners of The Cultural City of East Asia in 2021 have been chosen, with four cities in China, Japan and South Korea winning the title, the Chinese Ministry of Culture and Tourism announced on Sunday.
Shaoxing of East China’s Zhejiang Province, Dunhuang in Northwest China’s Gansu Province, Suncheon in South Korea and Kitakyushu in Japan were selected through votes held in their respective countries in 2020. Choosing Dunhuang and Shaoxing at the same time marks the first time that one country has selected two cities in the program.
These four cities are major cultural landmarks in their respective countries. Dunhuang was a major stop on the ancient Silk Road and is best known for its nearby Mogao Grottoes, which contain some of the finest examples of Buddhist art from a period extending 1, 000 years. Suncheon is an eco－city in South Korea that is a major agricultural and industrial center and also known for Suncheon Bay. Kitakyushu city was formed in 1963 through a combination of five big cities centered around the ancient city of Kokura. It is also where the already delayed 12th meeting of the three countries’ culture ministers will be held in 2021. Suncheon and Kitakyushu also won The Cultural City of East Asia in 2020.
These four cities are active centers for art and cultural communication. According to the announcement, the four cities will work closely together to promote cultural development and prosperity in East Asia through sustained cultural cooperation and close exchanges, and will jointly support the preparation and hosting of the Olympic and Paralympic Games in Tokyo in 2021 and the Winter Olympic and Paralympic Games in Beijing in 2022.
The “The Cultural City of East Asia” program was created based on an agreement reached at a meeting of ministers of culture from Japan, China, and South Korea in 2013. Every year one or two cities in each country are selected with the aim to develop their ties through culture and arts; those cities host a variety of cultural and artistic events to introduce traditional and modern arts and culture as well as different lifestyles to visitors.

4 . “Human activity has wiped out two-thirds of the world’s wildlife since 1970,” CNN reported on September 10, 2020. Later that month, the Guardian reported that “40 percent of the world’s plant species are at risk of extinction”. Stanford biologist Paul Ehrlich and his colleagues argued that “the ongoing sixth mass extinction may be the most serious environmental threat to the persistence of civilization”. Around the same time, the Daily Mail warned that “human civilization stands a 90 percent chance of collapse within decades due to deforestation”.
These horrible calculations and projections come from authoritative-sounding reports issued by international agencies, conservation groups, and peer-reviewed scientific journals. But is the future of wild nature and human civilization really so poor?
Data from uncontroversial mainstream sources strongly indicate that both humanity and the natural world are likely to be flourishing rather than collapsing at the end of this century. Humanity is becoming an urban species, and that’s good for the environment, since urban dwellers generally use less electricity, produce less globe-warming carbon dioxide, and have smaller land footprints than people living in the countryside. By 2100, it is estimated that 85 percent of people will be city dwellers, which would leave only 1.2 billion still living in the countryside. That means more space for the wildlife and less pollution from the agriculture.
The global tree-covering area increased by 865,000 square miles between 1982 and 2016. The researchers found that gains in forest area in the mild, subtropical and northern climatic zones are offsetting declines in the tropics. The Maryland researchers owe much of that increase to “natural afforestation on abandoned agricultural land”. “Furthermore, forests in mountainous regions are expanding as climate warming enables trees to grow at higher altitudes,” they added.
Humanity does face big environmental challenges in the coming century. But the scientific and economic evidence shows that most of the trends are positive or can be turned in positive direction by human wisdom. Rather than an age of extinction, the 21st century promises to be an era of environmental renewal.

5 . Motion sickness is an uncomfortable feeling. The sickness it causes can strike people on an airplane, playing video games, or, commonly, when riding in a car. In a future where people may find themselves running around streets in self-driving vehicles, the problems could get worse.
We typically sense our physical position and movement in the world by relying on our eyes, the feeling we get in our body, and our inner ear. Motion sickness may develop when there's disagreement between what your eyes see and what your inner ear senses. If you're looking at your phone in a moving vehicle, your eyes see a stationary screen but your inner ear feels that you're moving. The result of that dissonance can cause sickness. The common-sense solution is to just stop looking at your phone, but some of the appeal of self-driving cars is that you could use the time to be productive or entertained by what's on a screen.
Researchers of a car-making company and a video game company have been studying ways to address these issues. And their solution uses an interesting medium: sound. The research had two goals: to explore if sound could help relieve motion sickness, and to help people trust self-driving cars more. They experimented with two different categories of sound: tips that tell passengers what's about to happen, and noises that alert passengers when the device has noticed something, like a pedestrian.
The most convincing experiment took place on a closed airport runway in Sweden, near Gothenburg, in August of last year. On that track, brave participants had to ride in the backseat of a car driven by a human and read from a tablet while the car navigated the course. With just 20 people, the study was small, but according to researchers, the presence of sound tips made people report that they felt less ill. Participants said the sounds helped prepare them physically, or adjust their bodies for what was about to happen.

6 . Twelve-year-old Lydia Denton was recently named the winner of CITGO's Fueling Education Student Challenge, where she earned $20,000 after creating the Beat the Heat Car Seat, which is a portable device placed in the car seat that not only senses weight over five pounds but monitors temperature when the baby is in the seat.
The soon-to-be seventh grader says she became inspired to make the invention after watching the news that babies were being left in hot cars, often by accident.“At first, I thought about raising money for the families, but that wouldn't fix the problem: I wanted to invent something that could prevent the deaths from happening.”
Lydia's device is started when it senses the weight of the child and the temperature setting reaches over 100 F (38℃). At that point, an alarm goes off and a warning is sent via SMS to the parents. If the parents don't reset the device within 60 seconds, a built-in GPS chip sends a message to local authorities with the vehicle's location. After many rounds of testing with her local 911, Lydia is proud to say that Beat the Heat Car Seat is a success.
Though many newer vehicles come with warning systems and smart seat systems, Lydia's goal was to create a device that would reach more people and that could also transfer from car seat to car seat as the child grew. She decided to use her prize money to continue making improvements on the device, which would sell for only about $40.
Lydia is now working with an instructor who is helping her with production and teaching her about business. Lydia hopes that her work will inspire more kids of her age to make their ideas come true. “Don't think that you have to accept things in the world. If there is something that bothers you, think of ways to make it better!”

7 . True, people remember what you wear. After a social event, we all remember the woman in red, or the man with the top hat. On the red carpet, Hollywood hopefuls take advantage of this reality by wearing outfits designed to be discussed and displayed on the front pages of newspapers. But in terms of making a good impression, being memorable is not just about novelty or fashion, but attraction, both physical and emotional, often in opposite order of importance.
In a 2020 study, Andre Ndobo found people tended to remember the extremes: both attractive and unattractive faces. He acknowledged that one suggested explanation was that both are characterized by distinctive features that promote facial recognition when compared with faces of average attractiveness. But while distinctiveness is memorable, beauty is skin deep. Accordingly, the way you are remembered by others is often not about what you wear and how you look but about the way you make people feel.
Professional interaction can create positive personal memories. Adrie A. Koehler, in a piece entitled “In the Eye of the Beholder” (2017), found that when asked to recall their best learning experience, many students discussed a memorable teacher. What made the teachers memorable? According to the students, memorable qualities included not only teaching styles, but also interpersonal skills and positive qualities such as a sense of humor.
We can relate to the results of this study when recalling people who are memorable in our own lives. They are not always people who we believed to be the smartest or most believed, but often those who made us feel the most comfortable, and who were most interested in us. Sincere interest is uniquely attractive. Not only will you remember what someone said, but they will also remember you, fondly.
Regardless of what we wear or how we look, we are always naturally more appealing and approachable when we focus on others and when we are genuine rather than simply sociable. Remember that, and others will remember you.

8 . Ever wondered if dogs can learn new words? Yes, say researchers as they have found that talented dogs may have the ability to grasp new words after hearing them only four times.
While previous evidence seems to show that most dogs do not learn words, unless eventually very well trained, a few individuals have shown some extraordinary abilities, according to a study published in the journal Scientific Reports.
“We wanted to know under which conditions the gifted dogs may learn novel words,” said researcher xuekw Claudia Fugazza from the Eötvös Loránd University in Hungary. For the study, the team involved two gifted dogs, Whisky and Vicky Nina. The team exposed the dogs to the new words in two different conditions.
In the exclusion-based task, presented with seven known toys and one new toy, the dogs were able to select the new toy when presented with a new name. Researchers say this proves that dogs can choose by exclusion when faced with a new word, they selected the only toy which did not have a known name.
However, this was not the way they would learn the name of the toy. In fact, when they were presented with one more equally new name to test their ability to recognize the toy by its name, the dogs got totally confused and failed.
The other condition, the social one, where the dogs played with their owners who pronounced the name of the toy while playing with the dog, proved to be the successful way to learn the name of the toy, even after hearing it only 4 times. “The rapid learning that we observed seems to equal children’s ability to learn many new words at a fast rate around the age of 18 months,” Fugazza says. “But we do not know whether the learning mechanisms(机制) behind this learning are the same for humans and dogs. ”
To test whether most dogs would learn words this way, 20 other dogs were tested in the same condition, but none of them showed any evidence of learning the toy names, confirming that the ability to learn words rapidly in the absence of formal training is very rare and is only present in a few gifted dogs.

9 . American billionaire Elon Musk has demonstrated a technology designed to use a computer chip inside the head to control the brain. During a video demonstration on Friday, Musk provided details about the system, called Neuralink.
Musk says he hopes the technology can be used to treat neural disorders and help spinal injury victims regain body movement. Musk also believes the system could be used in the future to improve intelligence to help humans keep up with supercomputers and artificial intelligence (AI) technology.
During the show, Musk showed off a model of the Neuralink device. It is about 23 millimeters wide. It is designed to be implanted into a person's skull. Small wires would connect the device directly to the brain.
The Neuralink system is currently being tested in pigs, with plans to seek government approval for human testing sometime in the future.
A pig named Gertrude was also shown during the show. Musk explained that Gertrude had a Neuralink chip inside its head. The device is meant to record nerve activity in the pig's nose and mouth.
Musk said the company had three pigs, each with two chips. He described the animals as "healthy, happy and indistinguishable from a normal pig." Musk said the company was able to predict with "high accuracy" a pig's leg movement on a running machine using data from the chip.
Musk noted that Neuralink first wants to use the device on people with severe spinal cord injuries to help them talk and move using their brain waves. He said he is hopeful that, in the long term, those people could regain "full-body motion."
Some neuroscientists not linked to the company said the presentation suggested Neuralink had made great progress with the technology. However, they warned that many more studies will be needed to test the long-term success of such devices.
1. What good can the Neuralink device do to the disabled?| A．Making them think clearly. |
| B．Treating their diseases successfully. |
