China's first key national R&D project equipment for high-altitude wind energy — the world's largest 5,000-square-meter power-generating kite — (successful) completed all scheduled flight tests in Alxa Left Banner, North China's Inner Mongolia Autonomous Region, on Wednesday.

The China-made kite, (develop) under a national program led by China Energy Engineering Corp, achieved full in-air deployment and retraction (部署与回收) during testing, (mark) a solid step toward the engineering (apply) of high-altitude wind power technology in China.

Looking like a giant kite, the power-generating kite can collect wind energy above 300 meters high and transmit it to the ground through a tether cable (电缆) that drives a generator. The (late) test carried out the deployment and retraction of both a 5,000-square-meter kite and two 1,200-square-meter kites.

High-altitude wind energy, often described as untouched "no-man's land" of renewable power, offers significant potential thanks to its higher wind speeds, stable directions, greater energy density. Currently two main technological paths(explore) globally — airborne and ground-based systems — but there is still a long way to go. In the airborne approach, lightweight wind turbines (风力涡轮机) are fixed on flying platforms (generate) electricity in the sky. The recent test focused on the ground-based model, a working wind turbine deployed at high altitude captures wind energy to drive a ground-based generator.

Whether it's your smartphone, computer, GPS or calculator, being too dependent on these things is bad news for your brain. This is because your brain becomes less efficient and lazy if you reach for an easy, quick answer all the time. So every time you have a simple calculation to do, use your given internal machine, your brain.

Prioritize(优先考虑) quality sleep

It is vital for good brain function that you get the needed amount of sleep per night that the experts recommend. When you sleep, your body removes all the toxins(毒素) that have built up during the day, and also regenerates cells. Studies show that the best time to get to sleep is between 9 pm and midnight and to get at least 7-8 hours good quality, undisturbed rest..

Engage in mental workouts

There are many great ways to train your brain and keep it working and in check.. For more in-depth tips on brain training, one notable article outlines 10 effective ways to improve your memory and boost brainpower. You can search for it online.

Practice note-taking

It has been proven that writing down little notes and reminders for yourself actually helps to increase your brain power and is good for you. There are certain parts of the brain that are responsible for memories and memory.. Writing a journal, blog or email reminders can increase your brain capacity and ability to memorize important events or tasks.

A. However, this is not the case

B. Minimize dependence on technology

C. Writing notes can make fresh blood flow to these areas

D. Thus, ensuring high-quality sleep is essential for better brainpower

E. This means that once the brain matures, it is incapable of further development

F. Exercising your brain, like memorizing numbers or passwords, is highly beneficial

G. Regular physical exercise is fundamental to keeping and improving our overall health

In 2003, Jillian Clarke, a senior high school student, put the five-second rule to the test. She dropped cookies on the floor for five seconds and found that bacteria transmitted to food very quickly, even in just five seconds, thus challenging the popular belief.

A few years later, food scientist Paul Dawson and his students also tested the five-second rule and found over 99% of the bacteria transmitted from the floor to food in just five seconds. "The five-second rule was just ridiculous," Dawson concluded.

But in 2014, microbiology professor Anthony Hilton and his students restarted the debate. They studied the transmission of bacteria from a variety of indoor floor types to different food, with contact time ranging from three to 30 seconds. According to their results, the longer a piece of food was in contact with the floor, the more likely it was to contain bacteria. This could be seen as evidence in favor of the five-second rule, Hilton noted, but was not conclusive.

This motivated food science professor Donald Schaffner and his students to conduct a strict study on the accuracy of the five-second rule recently. They found that longer contact time resulted in more transmission but some transmission took place "instantaneously", after less than 1 second, thus debunking (驳斥) the five-second rule once and for all.

Your chance of falling ill after eating food that has touched the floor depends on factors like how dirty the floor is and the type of bacteria present. Based on studies, the kitchen floor is one of the dirtiest spots in the house because the kitchen gets a lot of foot traffic and kitchen waste often falls on the floor, creating an ideal breeding ground for bacteria. While most of the bacteria existing on kitchen floors are harmless, some can cause food poisoning.

The iceberg is officially known as A23a and it measures over 3,500 square kilometers. It has existed since 1986, when it broke off from the Antarctic shelf. But it didn't leave Antarctica until 2020. Scientists have been using satellite imagery to follow the iceberg's movements and their observations had shown the iceberg had not broken into smaller pieces like some other so-called "megabergs" that passed through the Southern Ocean. Predicting the iceberg's exact path is difficult, but ocean conditions suggest it should reach South Georgia in two to four weeks.

Scientists are worried the iceberg will get caught on the underground continental shelf around South Georgia. If so, it could remain there for months or it could break into pieces, which could harm efforts by penguins and seals on the island to feed and raise their young. Icebergs that have grounded there in the past led to the deaths of young penguins and seals.

But Raul Cordero, a member of the Scientific Committee on Antarctic Research, believes it is possible that the iceberg could miss the shelf and continue moving into open waters beyond South Georgia. The island acts as an obstacle (障碍) to ocean currents and therefore usually makes the water change direction long before it reaches the island. The iceberg is moved by that water flow, so the chances of it hitting are not that high. However, some iceberg pieces could affect the island.

It is summer in South Georgia and penguins and seals from the area have been looking for food in the cold Antarctic waters to bring back to their young. They might have to go around the iceberg if it gets stuck, which would take a lot of their energy, possibly leading to animal deaths. The seal and penguin populations on South Georgia have already been having a "bad season" with cases of bird flu.

I took that shot like a champion, without so much as a quiet "Ouch". While I waited for the doctor to come back with my balloon, I thought about all the cool things I was going to do with that balloon. The doctor returned with a concerned look on his face and delivered the unfortunate news. "I'm sorry, Andrew, but we're out of balloons."

All my big plans for that balloon popped faster than that balloon ever would have. I was devastated. The entire way home, my grandma kept telling me that I should think positively, and everything would be okay.

Arriving at home, I was straight going through the house to the backyard door, ready to go outside and tell my dog all my troubles, when I looked out and saw the most amazing thing my seven-year-old eyes had ever seen. Our entire backyard was filled with floaty balloons!

We lived less than a mile from an amusement park. As it turned out, when the wind was just right, the balloons released from the daily parades would land neatly in our backyard.

I will never forget that day of whirling through those balloons and thinking they were all for me because I had to get my shots. And I will never forget my grandmother telling me throughout my life that if you just think positive thoughts, everything has a way of working out in the end.

Museo Anahuacalli(Mexico City, Mexico)

Created by artist Diego Rivera in Mexico City's San Pablo de Tepetlapa neighborhood of Coyoacán, this museum is the world's first collection of pre-Columbian artwork. The difference is that you're experiencing art and culture in a museum built by someone with a passion for his root and cultural inheritance instead of a museum built by an academic group, which is pretty unheard-of.

Ghibli Museum(Tokyo, Japan)

If you know about Japanese animation, then you know about illustrator and storyteller Hayao Miyazaki. The museum, which explores his most famous projects, is considered one of the best in the world. In fact, tickets usually sell out immediately. If you want to get your tickets, you probably need to work with an online service.

Hong Kong Museum of History(Hong Kong, China)

What makes the Hong Kong Museum of History so endlessly explorable? First, Hong Kong has a fascinating history, one that involves a lot of cultures and traditions. Second, Hong Kong is tiny, meaning those cultures have been mixed up and changed into something unique and distinct, from its approach to national security to space exploration. Third, it's a top-ranking and award-winning museum that's free to the public.

Museum of Old and New Art(Berriedale, Australia)

Welcome to one of the coolest museums in the world — and one of the most controversial (有争议的), thanks to its hyper-experimental exhibits. With that being said, this is one of the coolest museums in the world thanks to the fact that it doesn't take itself too seriously. It's designed to be a hangout space where people can discuss art, debate it, and maybe even have a laugh.

Liam had never liked hospitals. But every Thursday afternoon, he walked through the double doors of the wards in Nationwide Children's Hospital, carrying a worn guitar and a bag full of puppets (木偶). After losing his younger sister to blood cancer five years earlier, Liam started volunteering as a hospital entertainer—quietly giving laughter where it was most needed.

He wasn't loud, or particularly funny. But he was gentle, patient, and kind. Most kids smiled eventually with his company, even the shy ones. When Liam played together with them, the kids were wild with joy. Some clapped along to his songs. Some asked to try the puppets themselves. Almost all doctors and nurses said his visits were better than medicine to some degree.

But actually, there was one patient he couldn't quite reach: Ava, a ten-year-old girl with a notebook always clutched (紧抓) to her chest. She rarely spoke, rarely smiled, and never made eye contact to anyone. She watched Liam's puppet shows from her bed, silent and still, showing no interest in anything around at all. Her drawings, though, told another story—skies full of stars, animals in suits, and people with wings. So strange was she that other kids also kept a distance from her.

Week after week, Liam kept trying. He used every puppet voice he knew, from silly, funny, to serious. He even brought in a little red hat for his main puppet, Charlie, hoping to make her laugh. Still, the girl gave no reaction.

Then one Thursday, as Liam packed up to leave, he noticed something new on her nightstand: a drawing of Charlie—the puppet with the red hat—holding hands with a girl who looked a lot like Ava. Liam felt a wave of warmth and surprise flooded into his heart.

He smiled and quietly left a note beside it: "Looks like he made a friend."

The next week, as Liam played his guitar as usual, Ava finally opened her mouth.

"Does your puppet have a name?" she asked, so softly that he almost thought he imagined it.
