1 . Chinese scientists say they have developed a robotic fish that can remove microplastic particles from water environments. Researchers working on the project say the robots could help to clean up plastic pollution in oceans around the world.
The robotic swimmers are about 1.3 centimeters long. They are made of a soft chemical Compound. The robots are designed to absorb microplastics while moving through the water. The project was launched by a team at Sichuan University in southwestern China. The researchers said the robots have already performed well in shallow water and they plan to carry out more tests in deeper waters. The scientists reported their findings in a new study in Nano Letters. The publication comes from the American Chemical Society, a nonprofit organization supported by the U.S. Congress. The robotic fish were built to target microplastic particles, which are smaller than five millimeters. Studies have confirmed that microplastic pollution has been discovered in many natural environments. The material comes from the breakdown of manufactured plastic products and industrial waste.
The team said the robots can be controlled by light. Turning “a near-infrared light laser” on and off causes the fish’s tail to move back and forth, the American Chemical Society said. The robotic fish can swim up to 2.76 body lengths per second. The researchers said this is faster than most similar soft robots. Wang Yuyan was a member of Sichuan University’s research team. She told Reuters news agency that the small, lightweight robot is currently being used to collect microplastics for research purposes. But Wang added that the team plans to expand that use so the robot fish can remove larger amounts of microplastic waste from deep ocean areas. The fish can take in different kinds of microplastics and even repair itself when damaged, the researchers said. And if a robot fish is accidentally eaten by a real fish, it can safely digest the material, the team added. Wang said similar robots could be developed to be placed inside the human body to remove unwanted materials or diseases.

2 . A new study warns 1,500 endangered languages could no longer be spoken by the end of this century.
The study, led by The Australian National University (ANU), identified predictors that put endangered languages at high risk. Co-author Professor Lindell Bromham said that of the world’s 7, 000 recognized languages, around half were currently endangered. “We found that without immediate intervention, language loss could triple in the next 40 years. And by the end of this century,1,500 languages could cease (停止) to be spoken.”
Their study finds the widest range of factors ever putting endangered languages under pressure. One finding was that more years of schooling increased the level of language endangerment. The researchers say it shows we need to build curricula that support bilingual education, promoting both native language proficiency as well as use of regionally-dominant languages. “ Across the 51 factors or predictors we investigated, we also found some really unexpected and surprising pressure points. This included road density,“ Professor Bromham said. He added, “Contact with other local languages is not the problem. But we found that the more roads there are, connecting country to city, and villages to towns, the higher the risk of languages being endangered. It’s as if roads are helping dominant (主导的) languages ‘steam roll’ over other smaller languages.”
Professor Bromham said the study’s findings were a vital reminder that more action was urgently needed to preserve at-risk languages. He added, “When a language is lost, or is ‘sleeping’ as we say for languages that are no longer spoken, we lose so much of our human cultural diversity. Every the languages predicted to be lost this century still have fluent speakers, so there is still the chance to invest in supporting communities to bring native languages back to life and keep them strong for future generations.”

3 . Exploring China is not easy even for experienced travelers, but the history instructor Jessica Gerard from Ozarks Technical Community College (OTC) knows from experience the trip is worth it. Since 2008, she’s led five groups of students across China to study its culture and history.
Gerard often reminds interested students that the trip is not a vacation—it’s an academic (学术的) course. “Anyone interested in the trip must take an online course about the history of China before they can go,” she said. “And, most importantly, students continue to learn while in China. They’re expected to listen to guides, keep a diary and write about their experiences afterward.”
OTC student Ross Weis believed his experiences in China easily transcended (超越) anything he could have learned in the classroom. In fact, it was his long-held interest in China that led him to ask about the trip after seeing a poster in the OTC library. “I’ve always been drawn to China and its rich culture and history,” Weis said. “My dad studied history in college, and I suppose that has some influence on me.”
Of all the cities and historical sites Weis visited, he said nothing could top his experience at the Great Wall. “I’d read about the Great Wall and seen it on TV, but it is so different to go there and actually experience it,” he said. “It wasn’t as worn as I had expected it to be. That was pretty cool.”
Every OTC group Gerard has taken to China has been led by her trusty tourist agent, Jim Lieu. Gerard plans her trips directly through Lieu, who keeps travel costs down for students. “Lieu and I have an excellent relationship with one another. He always knows what I want for my students, and I know what he can do,” said Gerard. “He sincerely believes that in order to build stronger communities and a better world, people around the world should get to know each other through travel.”

4 . What motivates you to work or study harder? Is it the thought of success and all the amazing things that you can achieve, or is it the fear of failure and worry about all the things that can go wrong for you?
A recent study looked at the effect of fear-based strategies on British secondary school students. It found that if a test is seen as important, and students are optimistic that they can succeed, then the fear of failure can be used successfully by teachers to motivate these learners.
Entrepreneurs often run the risk of failure. It’s a fact that many new companies will fail. But does this motivate or hold back business people?
A.Again, it’s not straightforward. |
B.The answer, undoubtedly, is “yes”. |
C.Taken together, fear-based motivation is complicated. |
D.Generally speaking, good outcomes can be expected by teachers. |
E.They may also be inspired to innovate and activate their business. |
F.However, if students lack confidence, fear-based approaches could cause anxiety. |
G.Leaders, managers and teachers often use one of these ideas to inspire people to achieve more. |
Peter, a 5-year-old boy, showed such great interest in seashells that he would rush to pick them up with his 3-year-old sister, Shirley. They screamed out their joy as Peter collected his treasure into his pockets. For Peter, sea shells lay shining on the peaceful beach, waiting for him, just like stars twinkling (闪烁) in the sky. As waves touched them, they seemed to be flowers blooming (绽放) in gentle wind.
One day, Peter was wandering through a market with Shirley with some shells in his pocket. Suddenly Peter found his younger sister was lagging (落后) behind. He stopped and looked back, finding Shirley standing in front of a toy shop and staring at something with great interest. The boy went back to her and asked, “What do you want?” Shirley pointed at the doll, wearing a smile on her innocent face. Peter held his younger sister’s tiny hand, walking into the shop. He tiptoed (踮起脚尖) to reach for the doll, and like fulfilling an elder brother’s duty, gave the precious doll to Shirley. Holding tightly the doll, the sister was very happy.
The shopkeeper was watching everything and enjoyed seeing the mature (成熟的) behavior of the boy. Now the boy came to the counter and asked the shopkeeper, “How much does this doll cost, Sir?” The shopkeeper was a cool man, who had suffered from something in his life. So he asked the boy with love, “Well, what can you pay?” Peter reached into his clothes for money that was intended for these two little kids’ breakfast. Having counted the money, Peter put it with care on the counter, asking again, “Sir, is it enough for my little sister’s doll?” The amusing scene just in front of the shopkeeper eventually brought a smile to his face. Shaking his head slightly, he replied, “My boy, I am afraid it seems not to be enough.”

6 . Diving in the ocean, marine biologist Erika Woolsey has seen how coral reefs (珊瑚礁) are being damaged by climate change. It has made her decide to find a way to share her experience —including those who can’t easily explore the ocean.
Through her non-profit, The Hydrous, Woolsey is using virtual reality to bring the ocean to everyone. Scientists, filmmakers and divers are taking people on immersive (沉浸式的) virtual dives, attracting attention to reef damage and expecting action to protect our sea. About 25% of marine species depend on coral reefs. However, climate change, pollution and overfishing have done harm to around half the world’s shallow water coral reefs.
Twenty years of underwater exploration has given Woolsey a detailed understanding of the dangerous situations facing reefs. “I’ve seen this first-hand shift. Healthy colourful coral reefs become what look like the moonscape step by step,” Woolsey says.
It is through this experience that The Hydrous team set out to recreate with their award-winning film Immerse. Intended to watch with a VR headset, viewers join Woolsey for a nine-minute guided virtual div e on the coral reefs, immersed in a 360-degree underwater view.
They swim alongside sea turtles and sharks before witnessing the worsening of the reefs. The experience often brings out strong feelings. “As soon as people take off that headset and look me in the eye, they want to tell me a story about their ocean experience,” Woolsey says. “It’s that human connection to our ocean that will solve our ocean problems.”
Woolsey hopes advances in camera technology will allow her team to take more and more people to places in the ocean that are underexplored and places further away from human civilization. They are developing a virtual experience that will put the people in the role of a marine biologist, carrying out biodiversity surveys underwater, and even transporting the viewers to space to monitor global sea surface temperatures.

8 . Of all the Chinese 24 solar terms, Clear and Bright (清明) is the only one whose first day is also a traditional Chinese festival, the Qingming Festival. The words “clear” and “bright” describe the weather during this period. Temperatures begin to rise and rainfall increases, making it an important time for growing crops in the spring. As is known, it is a time to worship ancestors, however, here are several things you may not know about Clear and Bright.
Spring Outings
Not only is it a period to honor the dead, but it is also time for people to go out and enjoy nature. As trees turn green, flowers blossom, and the sun shines brightly, everything returns to life. It is a fine time to appreciate the beauty of nature.
Flying Kites
Flying kites is an activity favored by many Chinese during Tomb-Sweeping Day. Kites are not only flown during the day time but also in the evening. Little lanterns are tied to the kites. And when the kites are flying in the sky, the lanterns look like twinkling stars at night. What makes flying kites during this day special is that people cut the string while the kite is in the sky to let it fly freely. It is said that this brings good luck and that diseases can be chased away by doing this.
Cuju
Cuju is an interesting game played during this period. Ju is a ball made of leather with hairs plugged in it. Legend has it that the Yellow Emperor first invented it for training warriors. Later, Cuju was used by people to build up their bodies when they were unable to eat hot food during the Cold Food Festival.
Feasting on Qingtuan
In the lower parts of the Yangtze River region, qingtuan is very popular on Tomb-Sweeping Day. Qingtuan is a kind of round green cake. In order to make the cakes, people mash (捣碎) barnyard grass (艾草) to squeeze juice from it and mix the flour and juice to a paste. Then they put fillings into the paste and steam them. Pretty and delicate, qingtuan has a special flavor.

9 . Bullet comments—comments which fly across the screen on certain video platforms—represent a ·modern approach to communication that young people use in cyberspace to express their ideas, emotions and feelings. When looking back, however, they are a good reminder of what was hot or trending in the past year.
On Dec 15,2023, Bilibili, a Chinese video-sharing platform, picked “Ah?” as the Bullet Comment of the Year. In 2023, “Ah?” appeared more than 13.2 million times on Bilibili as a bullet comment, according to Dazhong Daily.
Today, young people in China use “Ah?” to express their surprise and amazement. User Mo Xin filmed himself writing down the ancient Chinese text Hard Is the Road to Shu (《蜀道难》) in one stroke (一笔) and subsequently uploaded the video to Bilibili. This feat (壮举) resulted in the video winning the most “Ah?”bullet comments on the platform.
China’s huge technological advancements have also generated “Ah?” comments from Bilibili users. In August, China made a breakthrough in controllable nuclear fusion (可控核聚变) technology. Its new-generation “artificial sun” Huanliu-3 looks to open new doors in the world of nuclear fusion. Videos announcing this news were inundated (淹没) in “Ah?” comments.
Though simple and easily understandable, “Ah?” provides insights into young people’s interests. Their focus extends beyond mere entertainment, however. They also, use “Ah?” to engage with. commentaries, and scientific discoveries, indicating a deeper, more serious layer of interest. These “Ah?” comments reveal that young people are attentive to the world around them. “Ah?” has become their unique way of responding to contemporary events, using it as a tool to document today’s history.
Every year brings a new bullet comment of the year, but what never changes is how young people want their voices to be heard. Do you still remember which video got you to send an “Ah?” in 2023?

10 . As I write this, a Bob Seger song is stuck in my head. It’s been playing on repeat ever since I heard it in a movie. I hated it a lot when it first came out years ago, and I still really hate it now. Why, oh why, does an earworm happen? This phenomenon, known as an earworm, is both fascinating and annoying. Earworms are a type of auditory imagery, where we perceive a tone without actually hearing it. When a familiar song is heard and suddenly stopped, some areas of the brain become overly activated in expectation of hearing the rest of the song, and then it fills in the missing pieces.
Anyone can experience earworms, but certain personality characteristics, like openness to experience, may increase their frequency. You may have seen a popular TikTok recently of a guy saying earworms aren’t normal but are instead symptoms of ADHD (多动症) or OCD (强迫症). That’s generally not the case. “It is entirely normal to experience earworms: Over 90% of participants in large-scale surveys report having had earworms at least once a week, and they are not a symptom of any other underlying mental condition,” says Jakubowski. Interestingly, earworms aren’t all bad. Research indicates that they can enhance our ability to recall past events, as the repetitive nature of the song strengthens our memory.
There are several strategies to get rid of earworms. Listening to the entire song can help resolve the unfinished loop. Alternatively, distracting yourself with another melody or engaging in activities that require focus can also be effective. Chewing gum or eating something crunchy may interrupt the song playing in your head. Despite these strategies, sometimes the best approach is to simply accept the presence of the earworm and let it fade away naturally. In my case, trying to actively rid myself of the song only made it more persistent. It seems patience is key when dealing with these stubborn musical guests in our minds.
