Several days ago, a random man called the4, reporting that Maggie was aggressive (富于攻击性的) and5 other dogs in the park. It just so happened that Maggie made6 with a group of crows in the park. Maggie would7 play around with them, and they would follow her on our8. When the police showed up to question me about the report, she was playing with her crow friends. They saw Maggie9 crows and saw her "catch" one by touching it with her nose and then turn around to10 with that crow chasing her in return. It was so11 that she was playing and not using her teeth to bite the12 at all.

The policemen told me it was the first time they had ever13 such a thing that a dog played with crows like that. They could definitely tell that the man made a14 report. Whether they were aware of it or not, the crows potentially saved Maggie's life. What an unforgettable15 and it reminded me not to draw conclusions based on appearances or prejudices, but rather to make fair judgments through actual observation and understanding.

In 1405, a huge fleet of more than 300 ships manned by over 27,800 men set sail from Liujia Harbor near Suzhou on a distant voyage under the command of Zheng He. The fleet sailed along China's coast to Champa close to Vietnam and after crossing the South China Sea, visited Java, Sumatra and reached Sri Lanka finally. On the way back, it sailed along the west coast of India and returned home in 1407.

In all, he had made calls at over 30 countries and territories. No matter what country he visited, he called on the ruler of the land, presenting to him valuable gifts to express China's sincere desire to develop friendly relations. They sent the emperor zebras, giraffes, shells, elephant ivory and rhinoceros-horn medicine.

The voyages by Zheng He strengthened the friendly relations between China and other countries in Asia and Africa and led to cultural and economic exchange between them. Therefore, his expeditions could rightfully be called "one of greatest achievements in mankind's history of navigation".

A. Zheng served as commander of the fleet.

B. The response of the rulers was very generous.

C. On board the ships were large quantities of goods.

D. The Great Ming Empire launched a series of marine activities.

E. On each voyage, Zheng He acted as the representative of the Ming court.

F. All this had taken place about half a century before Columbus' voyage to America.

G. Zheng He's second and third voyages taken shortly after, followed the same route.

The study involved 172 people with an average age of 67 without memory problems. Participants had dental exams and took memory tests at the beginning of the study. They also had brain scans to measure the volume of the hippocampus at the beginning of the study and again four years later. For each participant, researchers counted the number of teeth and checked the amount of gum disease.

Researchers found that the number of teeth and amount of gum disease was linked to changes in the left hippocampus of the brain. For people with mild gum disease, having fewer teeth was associated with a faster rate of brain shrinkage, which is the same for people with severe gum disease having more teeth. After adjusting for age, researchers found that for people with mild gum disease, the increase in the rate of brain shrinkage due to one less tooth was equal to nearly one year of brain aging. Conversely, for people with severe gum disease, the increase in brain shrinkage due to one more tooth was equal to 1.3 years of brain aging.

"These results highlight the importance of preserving the health of the teeth and not just maintaining the teeth," Yamaguchi said. "The findings suggest that controlling the progression of gum disease through regular dental visits is crucial, and that teeth with severe gum disease may need to be removed and replaced with appropriate prosthetic ones."

Yamaguchi said future studies are needed with larger groups of people. Another limitation of the study is that it was conducted in one region of Japan, so the results may not be generalizable to other locations.

The HB-3 robot was inspired by how beetles (甲虫) move. It uses special materials that bend slightly when electricity is applied. These tiny movements allow it to walk with extreme precision — sometimes adjusting by just a billionth of a meter! The robot's built-in camera and computer let it "see" objects, plan paths, and perform tasks without human help. It also carries its own battery, lasting long enough to work freely in spaces up to 1.6 meters wide.

What makes the HB-3 stand out lies in its capacity to operate independently in environments such as sealed (密封的) laboratories, enclosed spaces filled with dangerous substances, or areas where dangerous materials are present. For instance, it managed to construct a functional electronic circuit within a space too small for human hands, placing parts like resistors and LEDs with 87% accuracy. Additionally, the robot has the ability to change its tools, using various devices suitable for different tasks. Researchers believe that in the future it could potentially repair machinery, or provide assistance in medical operations.

However, the HB-3 works slower than older models — taking about seven minutes to finish a task — because its small computer isn't powerful enough. The robot also struggles to judge depth accurately without extra cameras. While it placed parts correctly 87% of the time, mistakes still happen. Additionally, the current version hasn't been tested in extreme heat, radiation, or other dangerous conditions it might face in real-world jobs.

Engineers plan to make the HB-3 faster by upgrading its computer and adding side cameras for better 3D vision. Scientists believe that by combining beetle-inspired movement, wireless freedom, and smart tools, the HB-3 could change how we handle delicate tasks in factories, hospitals, and even space missions. As one researcher said, "Sometimes nature already has the best solutions — we just need to copy them at the right size."

Adler began helping his neighbors after the nonprofit project: HOMES gave a presentation at his local Rotary Club. Adler recalls the representative saying — "Too many seniors and disabled individuals need ramps, but they can't afford them." That's when Adler reached out to his friends so that they could start building ramps for neighbors in need.

"I feel this is my calling, and I'd like to start a crew," he told his friend Karen Scott, who was eager to jump in and help.

Adler's group of volunteers has only grown with time. Now when he pulls up to a house for an installation, he has about a dozen people by his side to transport lumber (木材), work the saws, and assemble the deck.

"It's turned into an amazing service," said Adler. "I really enjoy the process and the teamwork, and figuring out the best solution for people in need."

When a recipient (接收者) can afford it, they are only charged with the cost of the materials. If they can't cover the cost, project: HOMES steps in to pay the full price.

Adler and his team of volunteers have transformed lives by building over 500 accessibility ramps for households in need. Adler has gone from building one ramp per weekend to completing three, sometimes four ramps each week across the Tri-Cities area.

71-year-old Jaunita Barnes is one of the 500 neighbors that Adler has helped through project: HOMES. After a stroke and heart attack, Barnes found it difficult to navigate the stairs with her walker. She was confined to her home for months — getting groceries delivered and calling doctors to her door — until Adler and his team stepped in to help.

"Now I can go where I need to go," said Barnes. "Adler and the others are truly nice."

An emergency room doctor named Shane Naidoo participated in the New Jersey Half Marathon on September 28th. Despite his professional commitments and job demands, Naidoo has always found time to lace his running shoes up and hit the pavement. As an amateur athlete who had not been engaging in strict training in recent weeks, he had set relatively low expectations for himself. He had planned to simply enjoy the race and maintain a leisurely pace throughout. It turned out that although he finished last in the race, it was undoubtedly the most meaningful and unforgettable one.

Shane Naidoo was approaching the halfway mark of the New Jersey Half Marathon at Newport when Chrystal Rinehold, a female runner in her mid-thirties who was running just ahead of him, unexpectedly collapsed. The entire scene unfolded suddenly. One moment, she was maintaining her pace alongside the other runners; the next moment, she found herself on the ground, giving in to an unseen and mysterious force. Naidoo, who works at JFK University Medical Center in Edison, New Jersey, immediately rushed to her side along with four other runners who had witnessed this incident. His medical instincts kicked in as he swiftly began assessing the situation.

Upon conducting a thorough examination of her, he discovered that she was struggling to breathe and barely able to speak. She whispered in a weak voice, "I think I'm dying." Naidoo strongly suspected that she might be suffering from dehydration or low blood sugar levels. Such conditions could prove deadly for runners, especially during long-distance events like this one. Moreover, he also noticed that she was experiencing chest pain and in a disturbed mental condition. These symptoms were highly alarming and indicated a potential risk of cardiac arrest (心脏骤停). This situation demanded immediate and decisive action.

With the popularization of smartphones and the convenience of reading e-books, how can traditional brick-and-mortar bookstores transform (rise) to the challenge and break through in the decline? Dujiangyan Zhong Shuge is perhaps a very good example.

Inspired by the complex river system that exists in Dujiangyan county, the two-story space embodies Chongqing's unique geographical environment an "8D Mountain City". Zigzagging (曲折的) staircases are designed like mountain peaks, intertwined and complex. The ceiling is covered with mirrors, and being there (give) people the illusion (错觉) that the mountain stairs are piercing the sky, much like the magical space in "Harry Potter", fantastical and fun. In addition to the mountain-shaped stairs and mirrored ceilings (correspond) with Chongqing's geographical environment, the giant "lampshade (bookshelf)" that can be seen everywhere in the lobby of Dujiangyan Zhongshuge, look like endless mountain ranges.

Here, a city unfolds before your very eyes you listen to the dialogue between culture and wisdom, interpret the cultural thoughts condensed (浓缩) in a historical context, experience ancient feelings with a (poet) flavor, and picture the dream in your minds. it be the tile (瓷砖) technology used to represent ancient wisdom in the reading area, or the bamboo sea display in the (children) reading area that captures a sense of happiness and innocence, or the portrayal of natural scenery in the literary area, the design elements aim to create ideal destination for the soul, marked by the harmonious coexistence of livability and natural ecology.

For decades, scientists have been seeking sustainable solutions to global food shortages.. Commonly known as cultured meat, this innovation grows animal muscle tissue from stem cells in controlled laboratory environments. Its emergence could revolutionize our traditional understanding of meat production.

Animal-Free Meat Creation via Science

The manufacturing process begins with collecting animal cells through harmless biopsies. (活组织检查) . They are then placed in nutrient-rich bioreactors where they multiply and develop into muscle fibers. Surprisingly, the final product maintains the same protein content and texture as conventional meat through precise temperature control and mechanical stretching.

Environmental Impacts

Compared to traditional livestock (牲畜) farming, lab-grown meat shows remarkable ecological advantages. . A 2024 UN report revealed that cultured meat production requires 95% less land and reduces greenhouse gas emissions by 87%. Moreover, it completely removes the need for antibiotics (抗生素) used in raising animals, addressing growing concerns about drug-resistant bacteria.

Despite its promise, the industry faces significant challenges. Current production costs remain way too high, with a single burger patty costing approximately $50 to produce. Consumer acceptance also presents obstacles (阻碍), as 42% of participants in a global survey expressed distrust in "test-tube meat". Additionally, regulatory frameworks for safety standards and labeling requirements are still under development worldwide.

Future Outlook

Major food corporations have invested over $3 billion in cultured meat research since 2022. . With Singapore already approving commercial sales and the EU planning to legalize it by 2026, industry analysts predict cultured meat could capture 10% of the global meat market by 2035. As technology advances, this scientific breakthrough may fundamentally transform our dining tables and ecosystems alike.

A. Rising Production Costs

B. Challenges to Mass Production

C. It consumes 85% less water than regular farms

D. The most promising answer lies in lab-grown meat

E. These cells are carefully selected for their growth potential

F. Governments should promote this eco-friendly alternative

G. The huge increase in funding reflects growing confidence in it

The British philosopher built an entire philosophy around this idea — that we are all motivated by pleasure and pain. Lucky for him, then, that almost all of the social sciences today agree with him. More than that, many behavioral scientists believe we can game our own mechanisms of pleasure and pain and achieve anything. It's all to do with something called "Skinner's Law".

Skinner's Law, named after American behaviorist B.F. Skinner, is that when you are procrastinating (拖延) or finding a task hard to get on with, you have two choices: either "make the pain of not doing it greater than the pain of doing it" or "make the pleasure of doing it greater than the pleasure of not doing it."

The next question is: Is it better to promise yourself pleasure or to threaten yourself with pain to achieve your goal? It turns out that pain is by far the stronger motivator. Daniel Kahneman won the 2002 Nobel Prize for a theory called "Prospect Theory." He and Amos Tversky showed that we find pain more motivating than equivalent (等同的) pleasure.

Using all of this, here are two practical bits of advice:

Make a bet: Find a friend or a family member, and bet them some sum of money or some item you value that you will do a certain thing. "Okay, Dad," you might say, "if I'm not 5 pounds lighter by my birthday, you can have my PlayStation 5."

Social accountability: Tell everyone you're trying to do something. Tell them your target and your deadline. Keep people updated about your progress. This serves two purposes: to present the carrot and the stick. The carrot is that you get praise, support, and advice from your closest relatives. The stick is that you might be embarrassed or ashamed if you fail.

To dig deeper into this phenomenon, a team led by psychologist Jennifer Vonk and her co-author Brittany Greene embarked on a comprehensive investigation. They surveyed 412 cat owners or caregivers, asking them how their cat reacted after the death of another pet in the house. Participants used a five-point scale to indicate changes in the cats' behaviours in the days and weeks after the death. The recorded behaviours were numerous: altered sleep, eating and playing habits, increased vocalisation, spending more time alone, seeking human attention by sitting or lying near them, showing fear or curiosity, interacting with remaining pets, grooming changes, and even searching for the lost pet by sniffing its usual spots.

Respondents were also asked to describe the relationships between the cat and the deceased pet, as well as their own bonds and grief. This indicated that cats form connections and respond emotionally to loss.

It seems cats get sad when a companion dies, though it's hard to prove this. Some cats changed their eating and playing habits. Others sought more human interaction. And some even searched the house for their missing family members, lingering around the places where they used to play or sleep. Still, Jennifer cautions that there could be other reasons for the changes in the behaviour besides cats' grief. They might be eating more because they now have more access to the food bowl, or they might be playing less because they no longer have a playmate.

But, she says, even if they do experience grief, it's probably different from the kind that humans feel. It's more likely they're noticing that something has changed in their social environment, and they are responding to the change with feelings of fear or anxiety.

Then came the school career fair that changed everything. Dr. Eleanor Whitman from Harvard asked us to list our "hidden skills". My hand shook as I wrote "observing details"—something I'd learned from painting flower petals (花瓣). "That's medical research's most needed skill!" she exclaimed, sharing how a student turned microbiology notes into textbook illustrations. My lab partner whispered, "Remember our photosynthesis (光合作用) comic?" For the first time, my two worlds didn't feel so separate.

The real surprise came during hospital volunteering. Watching surgeries, I noticed something—the steady hands of doctors reminded me of my brushwork. When a boy struggled to describe his pain, I drew a fire-breathing dragon on his cast. "You made medicine speak," the nurse said. Slowly, my drawing pads filled with cells that looked like colored-glass art and X-rays arranged like abstract paintings.

Mr. Dawson, our career counselor, helped connect these dots. On his whiteboard, my medical knowledge and art skills overlapped in a bright yellow circle labeled "Medical Illustration". He showed me job listings I never knew existed—graphic designers for science apps, 3D modelers for anatomy (解剖) classes. "Your ‘impractical' skill makes you stand out," he said, pointing to my dragon drawing now used in pain management workshops.

Today, my microscope and paintbrushes share the same desk. The same hands that once hesitated between them now create 3D models of viruses for vaccine education. Sometimes I teach young patients to draw their feelings instead of describing them. My story isn't about heart and reality canceling each other out—they just multiply possibilities.
