Intermittent fasting is a time-restricted diet, where the day's calorie intake is consumed over an 8-12 hour period, with fasting for the remaining hours. Research tracking participants on such diets for three months to a year has shown benefits like weight loss, improved heart health, and better control of blood sugar. These reported benefits have made intermittent fasting a global trend.

However, not all outcomes of intermittent fasting are positive. A study published on December 13 in Cell is among the first to link intermittent fasting with hair loss. The study found that intermittent fasting could block hair follicle (毛囊) regrowth by causing programmed cell death in active hair follicle stem cells (HFSCs). Mice subjected to intermittent fasting showed slower hair regrowth compared to those with regular food access. Though similar results were found in humans in a small clinical trial, the researchers warned that the effects might be less serious in humans due to their slower body processes and different hair growth patterns.

The researchers discovered that intermittent fasting slows hair growth because hair follicle stem cells (HFSCs) struggle to handle oxidative stress (氧化应激) when the body switches from burning sugar to fat for energy. Normally, HFSCs switches between activity and rest, and hair regrowth depends on these cells becoming active. In the study, mice with regular food access had active HFSCs after being shaved, and their hair regrew normally. However, the fasting mice experienced programmed cell death in their active HFSCs, preventing hair regrowth.

Although these findings are significant, they are based on initial studies. Larger trials are needed to better understand how intermittent fasting affects hair growth, as individual responses may vary.

Running Tide was founded by Marty Odlin, an engineer and fourth-generation commercial fisherman. The Gulf of Maine is warming faster than nearly every other oceanic region, and Odlin has seen the changes firsthand. About 15 years ago, Odlin heard a talk from Klaus Lackner — the physicist who popularized the idea of removing carbon from the atmosphere. It clicked. "It was like, oh, this is right because there's no way we're going to get off fossil fuels in the next 50 years," he recalls thinking. "We're going to have to pull it down."

Using seaweed to draw down carbon would be an elegant solution — if it works. Seaweed forests collectively cover an estimated two million square kilometers and absorb as much carbon as the Amazon rainforest. But much of that storage is short-lived. When the seaweed is harvested, eaten by animals, or washes ashore, its stored carbon is released back into the atmosphere. Running Tide's model, in theory at least, would take that stored carbon and sink it to the ocean floor where it would remain for centuries, breaking down slowly.

Some scientists are careful about rushing ahead before fundamental scientific, environmental, and regulatory questions are answered. "Climate change is worsening, and people are panicking," says Kristen Davis, a professor of University of California Irvine, "but the science is not there yet to actually confirm that it's a good idea."

After graduating from Virginia Tech with a degree in engineering in 1956, Walsh was hired by Chrysler in Detroit. "That was the best decision I ever made, because if I'd gone to GM, I could have been lost in a big hurry," Walsh said. The engineer proved his ability while making $485 a month. "I was the youngest chief engineer at Chrysler at that time," Walsh recalled.

Walsh was asked by the manager in 1976 to design a vehicle unlike any other. Walsh's team didn't waste time. "We designed a prototype (原型) by cutting down the big vans," Walsh explained. But the plans Walsh led would sit on a shelf collecting dust. "We kept proving that it was workable through the prototypes," Walsh said. Then eight years later, Chrysler's new CEO Lee Iacocca greenlighted the project. "He thought it was a product that needed to be on the market," Walsh said. "It was decided to produce it in 1984." With its extra space for storing goods and roominess for passengers, the Chrysler minivan was an instant hit. "It became the cash cow of Chrysler Corporation," Walsh said.

After 32 years in Chrysler, Walsh retired in 1988 just four years after the first minivan was produced. "The world's best minivans and that is true," Walsh said. "It was a landmark vehicle."2024 marks the 40th anniversary of the minivan, proving good ideas are highly productive. The 93-year-old doesn't take credit for the minivan. To this day Walsh sings high praise for his talented team.

Admirably, the retired engineer helped introduce a new way of driving. "I enjoyed every minute of those jobs. That is all I have got to say," Walsh said. "I enjoyed every minute of my career. I am very fortunate to be there at the beginning."

Symbols of Animals in Chinese and Western Cultures

In Chinese and Western cultures, animals (acquire) different meanings over time. There are some elements represent one thing to one culture, and something else entirely to another.

The word "bat" in Chinese ("fu") has the same (pronounce) as the Chinese character meaning "luck, happiness and fortune". Therefore, images of bats are often symbols of good luck in China. They are also appreciated their ability to catch insects. , in Western cultures, bats are often associated with darkness.

Due to their unpleasant appearance and call, owls (猫头鹰) were for long considered symbols of bad luck in China. In consequence, owls were used in poetry( represent) evil. A poem in the Classic of Poetry, for example, was written in the tone of a (frighten) bird being bullied by an owl.

Owl. owl, as you have already taken my child, don't destroy my nest.

Yet in Western cultures, the owl is often regarded as symbol of wisdom. In the popular Harry Potter series, the owl is an (extreme) wise and helpful bird.

These differences mirror each culture's distinct background. By exploring these, a deeper understanding of the rich cultures around the world can (unlock).

In a video shared on TikTok, the girl was2 a difficult cheering stunt (特技) during an event organized at Chandler's Basha High School. She was doing flips (空翻) perfectly, getting3 into the air, and coming down safely into the hands of the supporters. But then, a flip in the air4 a problem. She couldn't land5 and was close to falling down. At that moment, her coach and another man stepped in to help.

This left her6. Thinking she lost heart, her coach said gently, "Honey, it's just a small7." But the girl said, "I won't give up though I'm8." The coach replied firmly, "Quite right, honey! You're so9. One failure doesn't mean anything. Let's give it one more10." The crowd in the sports complex, including seniors and school staff present, were11 for the little girl, too.

To everyone's amazement, the little girl12 it this time. All the audience stood up and clapped their hands for her.

This13 episode shows that, like many successful individuals, the girl was able to overcome difficulties with the right attitude and the14 of those around her. It's a powerful reminder that perseverance and encouragement can lead to remarkable15.

When preparing for exams, study groups allow students to share knowledge. For example, one might explain math concepts clearly, while another is strong in analyzing literature. Together, they fill gaps in understanding. A classmate's different viewpoint can turn a confusing problem into a solvable one, puzzle pieces fitting together to reveal a complete picture.

Cooperation also builds social skills. Imagine planning a class event: some prefer creative ideas, others focus on practical details. Through discussion, students learn to balance innovation and realism-a skill vital for adult life. Even disagreements, if handled calmly, become lessons in understanding others' feelings.

Working together helps overcome challenges. During tough times, like preparing for important exams, classmates can support each other emotionally. A shared laugh during a break or encouraging word before a test reduces stress. Research shows students in supportive teams perform better.

However, teamwork requires effort. Avoid relying too much on others or dominating discussions. A good team member contributes actively but also steps back when needed. Think of teamwork as a dance: everyone has a role, and harmony comes from cooperation, not chaos. Regular communication, like weekly check-ins, ensures everyone stays aligned (一致的) while respecting individual strengths.

So, cooperation is a bridge connecting individual talent to collective success. It prepares students not only for exams but also for future careers and relationships.

A. Teamwork makes learning more effective.

B. This simple truth applies to teamwork too.

C. Working on a team, you have the entire group's support.

D. They always stay motivated longer than those working alone.

E. Team members are under heavy pressure to make a decision.

F. Group projects teach us to listen, negotiate and respect differences.

G. For instance, let a teammate lead if he or she understands the topic better.

In daily life, we constantly process visual and auditory (听觉的) information to explore the world. For example, when watching a movie, the brain integrates images and sounds to create a unified experience. However, during movement-such as walking down a busy street-the brain may prioritize visual input over sound to avoid obstacles.

Until now, the neural mechanisms (神经机制) behind this sensory prioritization remained unclear. Understanding this process is particularly important for individuals with sensory processing disorders. such as autism or schizophrenia, where the brain. may grapple with integrating sensory information effectively. By uncovering how the brain naturally shifts between sensory inputs, researchers hope to pave the way for better treatment for these conditions.

To investigate this phenomenon, the research. team conducted behavioral experiments on mice, monitoring real-time brain activity using miniature microscopes and optogenetics, a technique that uses light to control neurons. The mice were trained to respond to both visual and auditory cues while either stationary or running on a treadmill.

The results revealed a striking shift in sensory reliance: When stationary, the ice relied more on auditory cues to make decisions. When moving, their brains prioritized visual input. This suggests that the brain dynamically adjusts sensory weighting based on behavioral context. Sound may be more useful for detecting nearby events when still, whereas vision becomes critical during movement for spatial navigation and stability.

This discovery could have important implications for understanding and treating sensory processing disorders, where the brain may struggle to properly prioritize sensory inputs. Dr. Lee explained, "Our findings demonstrate how the brain flexibly shifts between vision and hearing depending on behavior. Understanding this natural adaptability could lead to improved treatments for those with sensory integration difficulties."

The Hidden Life of Trees argued that trees are social. It shows that they can be our saviors. But it's terribly hard to let ourselves be saved. We think we can be the authors of our salvation (拯救). Of course, there are things we could and should be doing, but in terms of forestry practice, often what's billed as part of the solution is part of the problem.

Anyone who has planted a tree in their garden knows that it has a far-reaching effect — it makes your garden cooler in summer and warmer in winter. Forests cool by transpiring (蒸发). If there's no water, there's no cooling. Drought can kill trees fast, but trees have many ways of dealing with it, and Wohlleben sets them out. As a species, we have survived many climatic changes by changing our behavior — and that's how trees survive, too. Trees learn from their past harms and produce younger ones programmed with those lessons. They regulate their growth by changing the rate at which they drip (点滴)-feed them with sugar solution through root networks.

Deciduous (落叶的) forests in particular remove greenhouse gases effectively as long as they live. Cut them down and burn them and you're releasing carbon dioxide not just from the wood, but also from the forest floor. Deciduous trees are not "harvest-ready" at 200 years: they are teenagers. We must interrogate comforting expressions such as "renewable energy", and learn the real cost of our toilet paper.

If we don't learn to do nothing about trees, they will eventually be alone anyway—but without us. Wohlleben brilliantly and readably shows us how urgent and how hard it is to do nothing.

I was already aware of the issues facing the food system:   industrial farming ruining soils,   unclear supply chains leaving citizens powerless in making the right buying decisions, and the dominance of ultra-processed foods with zero nutritional value in supermarkets. But this encounter made me see how normalized it was to expect food out of season.

After graduating, I worked at Wall Street in New York, managing portfolios (投资组合).   Despite the breathtaking view and fast-paced stock market, I was troubled by the greed underlying my work. Cooking was my escape. It had always been a passion, whether in Buenos Aires, at university, or in New York.

As I neared my 30s, I knew I needed a change and food became my north star. Through my work visiting markets and farmers around Europe, I saw first-hand why seasonality is critical in our ability to regain control of, and fix, our food system. All around me I could see how quickly flavour was disappearing from our plates. I wanted to reintroduce phenomenal flavour into people's lives, and to re-educate and reconnect consumers with nature. In 2004, I took over Natoora, a French-founded company with a small base in London, determined to reintroduce great flavor to people's lives and reconnect them with nature.

My two-decade-long devotion to flavor, initially a pursuit of personal pleasure, has given my work a deep sense of purpose. Flavor can emotionally connect us to food and bring joy back into our relationship with it. Changing careers opened a new world for me, filled with purpose and love for my work, and I hope it inspires others to fight for a better food-centric world.

An 80-year-old man was sitting on the sofa in his house along with his 45-year-old highly educated son. Suddenly a crow (乌鸦) landed on their window.

The father asked his son, "What is this?" The son replied, "It is a crow." After a few minutes, the father asked his son for the second time, "What is this? The son said, "Father, I told you just now. It's a crow."

After a little while, the father asked his son the same question for the third time, "What is this?" At this time, some expression of anger was felt in the son's tone when he said to his father. "It's a crow, a crow." A little while later, the father again asked his son for the fourth time, "What is this?"

This time his son shouted at his father, "Why do you keep asking me the same question again and again although I have told you so many times ‘IT IS A CROW'? Are you not able to understand this?"

A minute later the father went to his room and came back with a diary, which he had kept since his son was born. On opening a page, he asked his son to read that page: Today my little son aged three was sitting with me on the sofa when a crow suddenly landed on the window. My son asked me 23 times what it was, and I replied to him all 23 times that it was a crow. I hugged him lovingly each time he asked me the same question. I didn't at all feel angry, but instead felt affection for my innocent son.

Paragraph 1:

After reading the diary, the son was filled with tears and began to reflect on the days when he used to sit together with his father.

Tang suits (Tangzhuang) refer to a type of Chinese jackets. The word of Tang suit (create) by the overseas Chinese people decades ago.

the most prosperous and powerful dynasty in the history of China, the Tang Empire (618—­907) was so famous in the world that foreigners call the overseas Chinese people "the Tang people", the places they live "Chinatowns (literally meaning Tang People Streets)" and the clothes they wear "Tang suits".

A Tang suit has two (vary) in Chinese culture, which are different from each other in style. The one that is familiar to us refers to the real Tang­era clothes (develop) from Hanfu, which leaves an impression of comfort and elegance. What is a typical design of a Tang suit is it employs the Chinese characters, such as fu (happiness) and shou (long life) to express good fortune and best wishes, which is very popular among the Chinese people owing to its (culture) significance.

As unique part of traditional Chinese culture, Tang suits are worn by overseas Chinese people during the Spring Festival each year, (attract) many foreigners to try them out of curiosity. More and more young Chinese people are willing to wear Tang suits instead of Western­style ones on their memorable occasions. The Chinese TV presenters also prefer wearing Tang suits during TV shows, (especial) at Spring Festival Galas.

Walker quickly1 traditional Chinese emergency methods for the girl, as CPR (心肺复苏术) might not have been as2 and there was a3 of breaking her bones on the hard ground.

Walker phoned his teacher Song Zhaopu and, under his4 guidance, sprayed5 water on her face and6 her elbow area. After over 20 pats, the girl started to7, and she could speak a few words.

Traditional Chinese medicine8 that tapping the elbow area can help clear energy paths and improve blood flow. Spraying cold water on the face was an9 method to make someone conscious by stimulating the skin.

Faced with newfound fame and praise online, Walker10 said: "It's not me, it's the wisdom of the ancients. I just11 what my teacher taught me." He believes that it's patients who are helping the doctors, as being a doctor12 constantly gaining and testing experience through practice.

Joel Mikael came to China in 2015 and following a year of13 Chinese language study, he went to Henan University of Chinese Medicine.

In the early stages of his journey into the traditional Chinese medicine, Walker always14 some Chinese herbal medicine by himself, just like Shen Nong, a character in Chinese legend, who tasted most of the herbal medicine himself to know their properties and healing15.

The questions were based on moral foundations theory, aiming to understand why morality seems to follow similar patterns among people from diverse cultures. According to this theory, morality can be categorized into five foundational values — care, fairness, loyalty, authority, and purity. These values fall into two groups: individualizing values and binding values.

Not all types of values exhibited a clear seasonal pattern. For example, individualizing values, which emphasize the morality of individual rights, showed little variation over time and did not follow a seasonal trend. In contrast, binding values — those that prioritize group needs, such as loyalty, respect for authority, and purity of tradition — followed a biannual (一年两次的) pattern.

To gain deeper insights into their findings, the researchers also studied patterns in Google search results related to anxiety. They discovered that population-level anxiety also followed a seasonal cycle — peaking in spring and fall, suggesting a possible correlation (关联性). Spring and fall are generally considered the most enjoyable seasons, so an increase in anxiety during these times may come as a surprise. But it's possible that increases in school and work-related changes during these times could play some role. They also suggest that anxiety may decrease in winter due to seasonal holidays, and in summer because of warmer weather and increased vegetation (植被).

"We often perceive moral values as unchanging principles that we hold close," says Professor Hohm. However, they are actually influenced by various factors that we may not notice. Understanding how this happens can help us better comprehend and plan for seasonal shifts.

But what if there were a way to relieve the tedium of exercise while still getting a good workout? Luckily for us, there's virtual reality.

Many VR games are played while standing. In order to play properly, the player is forced to move around swinging their arms or using their legs. After an hour of this on a regular enough basis, it's not surprising that many people unexpectedly find themselves a little fitter. There are already a number of virtual reality games which, intentionally or not, result in their player ‘getting a good sweat on' if played for enough time. For example, there's a first person shooter which forces the player to sidestep, duck and other sport actions. That's cardio (有氧运动). Or there's a music game which forces players to shadowbox in order to hit the notes—that's an upper-body workout.

The potential for VR to help people get fit has been noticed by one company. They want to take the whole experience into the gym. They are making a resistance machine, designed to be used in combination with a VR headset. Players challenge a virtual opponent in a series of games, which results in a 30-minute full-body workout. However, the cost of the equipment is expensive and there are safety concerns to be worked out. So don't hang up your gym shorts just yet.

Although it's early days, for those of us who struggle to keep passionate about exercise, anew solution could be coming. And a world where a person can exercise and have fun at the same time might be something that many people would want—virtual or not.

The trail was steep and tough, with sections that seemed almost insurmountable (不可逾越的). As I climbed, my legs burned, and my breath grew short. There were moments when I wanted to turn back, to retreat to the comfort of the familiar. But something inside me urged me to press on, to see what lay beyond the next bend. It was in these moments of doubt and exhaustion that I began to reflect on the nature of perseverance.

Perseverance, I realized, is not just about pushing through physical pain or mental exhaust. It is about maintaining a sense of purpose, even when the destination is unclear. It is about trusting that the effort we put in will eventually yield results, even if those results are not immediately visible. This lesson was not new to me, but experiencing it in such a real way brought it into sharper focus.

As I continued my climbing, I noticed how the landscape changed with each step. The dense forest gave way to open meadows, and the air grew cooler. The higher I climbed, the more expansive the view became. It was a powerful reminder that perspective is everything. What seems like an insurmountable obstacle from one point can appear entirely different from another. This shift in perspective can be transformative, allowing us to see challenges not as roadblocks but as opportunities for growth.

By the time I reached the summit, I was exhausted but excited. The view from the top was breathtaking, a reward for the effort it had taken to get there. But more than the view, it was the journey itself that left a lasting impression. The climb had taught me valuable lessons about resilience, perspective, and the importance of staying the course, even when the path is difficult.

Life, like the mountain trail, is full of challenges that test our limits and push us to grow. It is through these challenges that we discover our strength and resilience. And while the journey may be difficult, the lessons we learn and the perspectives we gain make it all worthwhile.
