Traditional e-skins, while innovative, have been limited by their dependence on multiple sensors and large power sources. "Previous designs were like smartphone touchscreens with countless individual sensors," explained Dr. Denys Makarov, lead researcher at the Institute of Ion Beam Physics. "Our major breakthrough was developing a whole system that imitates how human skin actually works. This is mainly what sets it apart from previous e-skins."

The new e-skin consists of a remarkably thin membrane (膜), which is both flexible and breathable. Unlike earlier versions that could cause discomfort to real skin, this design allows air and moisture to pass through, making it comfortable to wear. The key innovation is a magnetosensitive functional layer that serves as a single, continuous sensor surface.

Pavlo Makushko, the study's first author, compares the technology to human biology, "Just as our skin sends all touch signals through nerves to the brain, our e-skin uses one central processor to interpret magnetic signals across its entire surface." This efficient design significantly reduces energy consumption compared to conventional e-skins.

The research team adapted principles from medical tomography (影像) to achieve unheard-of precision in locating magnetic signals. This approach overcame previous limitations in sensitivity that had prevented similar developments.

Looking ahead, the researchers imagine this technology bridging the gap between human and machine interaction. "It creates a completely new communication channel," Makarov noted, emphasizing how the e-skin's magnetic sensing avoids disturbance from other electronics. As development continues, we may soon see this innovative e-skin integrated into everything from wearable tech to advanced robotics.

Scientists believe Mars was once a mild world with flowing water and a protective magnetic field (磁场), which was suitable for the survival of living things. "Around three billion years ago, something disastrous happened," explains Ken Farley, Perseverance's project scientist. "The planet's magnetic field disappeared, solar wind took away the atmosphere forcefully, and Mars became the uninhabitable world we see today."

Perseverance's primary mission is to search for signs of ancient tiny living organisms. The rover is equipped with precise instruments to analyze rocks and soil, but its most important task is collecting pure and undamaged samples for detailed study on Earth. "Each sample tube we fill could hold answers to questions about Martian history and whether life ever existed there," says Meenakshi Wadhwa, lead scientist for the Mars Sample Return program.

In June 2024, NASA's Curiosity rover discovered yellow sulfur crystals — an exciting find. However, only Perseverance can collect samples for return to Earth, making its mission uniquely valuable.

The ambitious Mars Sample Return program, a cooperation between NASA and ESA, aims to retrieve these samples by the early 2030s. The process involves multiple spacecraft working in sequence to launch the samples from Mars' surface and safely deliver them to Earth. Once here, scientists worldwide will study them using advanced laboratory techniques unavailable on the rover itself.

"These samples may hold clues not just about Mars, but about how planets evolve and how life begins," Wadhwa emphasizes. As Perseverance continues its journey across the Martian landscape, each new discovery brings humanity closer to answering one of our most profound questions: Are we alone in the universe?

Liu Jiakun was born in 1956. His architectural adventure started, playing in the corridors of the large brick hospital where his mother worked as a doctor. "From the rooftop, I could see the whole city," Liu recalled in an interview, describing how these early experiences shaped his perspective on urban spaces and community life. After graduating in 1982, Liu's career took a special path. While working for a state-owned architecture firm in Tibet, he also developed a strong passion for writing. "I had two identities then," he explained. "By day I was an architect, by night a writer." This creative life would later profoundly influence his architectural philosophy.

Liu's designs skillfully combine traditional Chinese elements with modern functionality. His West Village commercial complex in Chengdu(2015)is a typical example of this approach, transforming an entire city block into a lively public space with buildings, bike paths and pedestrian walkways that reexplain traditional Chinese urban planning for modern needs.

The Pritzker judges particularly praised Liu's"respect for culture, history and nature."Remarkable projects include the Novartis Pharmaceutical Building in Shanghai, which features dramatic balconies inspired by ancient Chinese architecture, and the Luyeyuan Stone Sculpture Art Museum, evoking(唤醒)the peace of classical Chinese gardens.

Perhaps Liu's most painful creation is his"rebirth brick" project following the deadly 2008 Sichuan earthquake. Using straw and stones from the fallen buildings, Liu developed these special bricks to help rebuild communities. "Each brick carries history," he said, highlighting how architecture can represent both memory and restoration.

In his Pritzker statement, Liu described his design philosophy in a poetic way, "I dream to be like water — adapting to each place's unique qualities while gradually solidifying into architecture that honors both tradition and innovation."

Upeoming Events

It was a sunny Saturday, and the sky was a clear, brilliant blue. Emily, a ten-year-old girl with wild curls, skipped down the path to the local farmers' market, her pink sneakers bouncing with each step. She clutched a carefully saved five-dollar bill, its edges worn from countless folds. Her goal was simple: buy fresh strawberries for her mom, who had been feeling down after a long week at work. Emily remembered how her mom used to love making strawberry pies, and the sweet aroma (香味) always brightened her mood.

As she reached the market, colorful stalls and a medley of scents greeted her — the earthy smell of vegetables, the sweet fragrance of flowers, and the warm aroma of baked goods. Vendors called out their best deals, their voices rising and falling in a lively chorus. A group of children laughed nearby as they chased each other around a stall selling handmade toys. The sound of coins clinking in cash registers mixed with the cheerful chatter of shoppers. Emily's eyes sparkled at the plump, red strawberries. Just as she was about to approach a stand, a soft whimpering (哀鸣) caught her attention. Following the sound to a corner, she found a small, dirty puppy with big, sad eyes. Its thin body trembled, a tight rope leaving a mark around its neck. The puppy's fur was matted, and its ribs showed through its skin.

Emily's heart melted. She knew she had to help. With the five-dollar bill in her hand, she was considering how to get the best of both worlds. Thinking of her mom, yet unable to ignore the puppy's suffering, Emily made up her mind. She bought a loaf of bread and fed the puppy, whose tail wagged weakly. Suddenly, a stern voice interrupted them. "What are you doing with that stray dog?" Mr. Thompson, the market security guard, approached her with a serious expression.

Social media, while increasingly criticized for spreading fake news and enabling cyberbullying, poses one of our era's greatest dilemmas: balancing its benefits against risks to children's health. A rarely (discuss) issue is children's being exposed to social media advertising, particularly (ethic) problematic junk food promotions.

Young children struggle to differentiate ads from regular content, even older ones, though aware of marketing intent, remain unconsciously influenced. Junk food ads, linked to obesity, intensify moral concerns. Despite governments' duty to protect children, few nations (regulate) such advertising effectively so far.

Regulators traditionally focus on ads "targeted especially at" children, are limited to TV or billboards near schools. However, the WHO emphasizes reducing children's overall (expose) to junk food marketing, including indirect ads during family TV programs or sports events.

In the social media era, platforms exploit user data — age, location, psychological traits — (target) the children most interested in unhealthy products. Alarmingly, this precision now offers regulators a tool. Ireland's Health Department introduced a code (state) that HFSS (high fat, sugar, and salt) food ads on social media "shall not target under-15s." the code is voluntary and age verification remains uncertain, it marks progress by covering all social media. To protect children, global cooperation (require). However, this initiative highlights a path forward.

Together, forestry and agriculture are responsible for 24% of greenhouse gas emissions, making deforestation a significant contributor to climate change.

Deforestation impacts the amount of greenhouse gases in the atmosphere in two ways. Second, trees play a critical role in absorbing the greenhouse gases that fuel global warming. Fewer forests mean larger amounts of greenhouse gases entering the atmosphere and increased speed and severity of global warming. In addition to helping regulate the earth's climate, forests provide habitats for over 80% of the plants and animals that live on land, but deforestation destroys these habitats, diminishing biodiversity. This also affects the more than 2 billion people relying on forest as sources of food and shelter.

The biggest driver of deforestation is agriculture. Farmers chopped down trees in order to plant crops like soybeans, palm trees and coco, or to make room to raise livestock for beef. Logging operations, which provide the world's wood and paper products, also cut countless trees each year. as land is developed for dwellings.

Efforts such as managing forest resources, eliminating clear cutting, and planting new trees to replace those removed are already being made to reduce deforestation environmental impact on our planet. And while some plants and animal species are gone forever, combating deforestation can help prevent further loss of biodiversity.

A. Why should we care about deforestation?

B. Many animals and plants will go to extinction.

C. Forests are also destroyed as a result of urban growth,

D. The effects of deforestation are grave but not irreversible.

E. As a result, many rainforest species go extinct each year.

F. Forests are very important for the expansion of urban areas.

G. First, when trees are cut, they release the carbon they are storing into the atmosphere.

In the first study, 105 participants and Chat GPT were each given three tasks, with three prompts for each task. They were asked to create humorous phrases for common acronyms, come up with funny answers for fill-in-the-blank phrases, and compose "roast jokes." The 105 participants generated over 945 jokes, while Chat GPT produced 180. Another group of participants then rated the funniness of these jokes without knowing their authors. Surprisingly, nearly 70% of them found ChatGPT-generated jokes funnier than those made by humans. Only about 25% thought human-crafted jokes were better, and around 5% considered both equally funny.

To further test Chat GPT's humor-generating ability, researchers conducted a second study. They asked Chat GPT to create new headlines in the satirical style of The Onion, using the original The Onion headlines as references. Then, 200 participants rated the funniness of both the original The Onion headlines and the Chat GPT-generated ones. The result showed that Chat GPT's headlines were regarded as equally funny as the original ones.

Gorenz, an amateur stand-up comedian, got the idea for this study from the ongoing debate in the entertainment world about the use of large language models like Chat GPT. With Hollywood writers and actors striking due to concerns that such models threaten their jobs, art, and creativity, the study has significant implications. For ordinary people, Chat GPT can add humor to daily conversations. However, for professional comedy writers, large language models pose a serious employment threat. Whether AI will have the last laugh in the field of humor creation remains an open question.

Dr. Laura Harris, a renowned education researcher, states, "Cooperative learning is not just about group work; it's a dynamic process that can significantly enhance students' social skills, critical thinking, and overall academic performance. It creates an environment where students actively engage with each other, which is essential for their growth." However, she also acknowledges that proper guidance and organization are crucial for its success.

One of the key advantages of cooperative learning lies in its ability to foster social interaction. When students work in groups, they learn to communicate effectively, listen to different perspectives, and resolve conflicts. For example, in a literature discussion group, students may have varying interpretations of a novel. Through dialogue, they can expand their understanding, learn to respect others' viewpoints, and improve their own analytical skills.

Cognitive psychologists explain that cooperative learning also promotes deeper learning. According to the Social Constructivism Theory, knowledge is constructed through social interaction. When students collaborate, they build on each other's ideas, challenge assumptions, and construct new knowledge together. This process encourages active thinking, rather than passive absorption of information.

Despite these benefits, cooperative learning is not without its problems. Some students may become free riders, relying on their group members to do most of the work. Others might struggle to express their opinions in a group setting, especially if the group dynamics are not well-managed. Additionally, teachers need to carefully design group tasks and monitor the progress to ensure that every student is actively involved.

To address these challenges, educators can adopt several strategies. For instance, clearly defining individual responsibilities within the group can prevent free-riding behavior. Encouraging equal participation through rotating leadership roles and creating a safe and inclusive atmosphere can help shy students feel more comfortable sharing their thoughts.

In conclusion, cooperative learning has the potential to transform the learning experience. By understanding its benefits and challenges, and implementing appropriate strategies, educators can harness its power to create a more engaging and effective learning environment. After all, learning is not a solitary journey, but a collaborative adventure.

A coach's real job, the story shows, is not to solve problems directly but to build inner strength. Over 10 months, Lily's coach worked with her to create ways to manage stress and rebuild her confidence in her skills. They made careful answers to hurtful comments like "Your project really failed, didn't it?" to help her face such words without breaking down.

During a key meeting, Lily still focused too much on her mistakes, seeing them as a sign of her lack of ability. The coach then told a personal story: once, after preparing a lot for a public speech, they made mistakes in some parts but were still praised for their try. This was to show that blaming oneself often exaggerates errors—mistakes in what you do don't decide your value.

Lily stopped and then said she had been being too hard on herself for no good reason. She realized failure was a lesson, not the end of everything. Slowly, she started to take on small projects, each time telling herself about her progress. Her worry reduced, and her courage came back.

Six months later, the coach received an email with an invitation to Lily's promotion party. The invitation showed her great change: from a woman defeated by one setback to a confident worker who saw challenges as opportunities to grow. It proved that coaching is mainly about guiding the way to self-acceptance—turning the shadow of failure into a step for success.
