Now a group of scientists have tracked down one more need for such equipment. In a paper in Royal Society Open Science, they propose that astronauts living on NASA's planned lunar base could run on the track to prevent their bodies from wasting away (变得消瘦、 衰弱) under the Moon's reduced gravitational pull.

In low-gravity environments, muscle decreases in strength, bone becomes easily broken and fitness and motor abilities decline. Even exercise, made less effective by weightlessness, struggles to counteract such effects. Alberto Minetti from the University of Milan wondered if running in a Wall of Death might provide a workout capable of limiting the body's decline. To test it he rented a 10-metre-wide Wall of Death and called in two brave volunteers.

His team tied the volunteers, a man and a woman, to ropes hanging from a crane (起重机) above the track. The ropes relieved the volunteers of five-sixths of their body weight, in effect mirroring the Moon's gravity. After some practice rounds, the volunteers could run parallel to (与……平行) the ground at speeds averaging around 20 kph, without assistance.

Dr Minetti says such motion can generate a force on the body similar to the effect of gravity on Earth. According to his calculations, running this way may be enough to battle the negative effects of lunar life. NASA may not even need to find extra room: he suggests that if the lunar shelters for the Artemis Base Camp were built in a circular design, astronauts could simply go for a jog around the inside walls. In principle it is "not a completely crazy idea," says Kevin Fong, a doctor and specialist in space medicine at University College London. But, he adds, the limited medical care available in space means he would be nervous about astronauts running at speed.

Every October, I beg my parents to take us to a pumpkin patch (园地) and every October it doesn't work out. That's why I couldn't believe my ears when my dad came home with the world's best news.

"Guess what!" he said. "I just saw a poster for the jack-o'-lantern (南瓜灯) design party in the Pumpkin Patch, and it's not too far from here."

"No way!" I said. "Can we go?"

"Pumpkin! Pumpkin! Party! Party!" chanted my little brother, Tex.

"Let's go! But I've heard a rumor that something terrible happened there." said my dad, worried.

Within minutes, Tex and I already jumped into the car and buckled up, ready to go. "I'm going to pick the gian test pumpkin," said Tex.

"Giantest isn't an actual word," I said.

"I' m going to pick the bestest pumpkin!" shouted Tex.

"I'm pretty sure bestest isn't an actual word either." I giggled. "I'm going to pick whichever pumpkin will make the scariest jack-o'-lantern."

"All right, boys! Too much excitement! What if something really goes wrong?" my dad cut in.

No response. My dad continued, "If plan A fails, we can get creative and come up with Plan B!"

Still no response.

Tex and I continued our excitement, giggling and chatting.

The drive was extra cool because we saw all kinds of Halloween decorations along the way.

"Look!" Tex said, pointing to twinkling orange lights and a flashing Pumpkin Patch sign.

"Yeah! Yes! It wasn't too far a drive," I said. "Watch out, pumpkins! Here we come!"

Coming into our sight were pumpkins of various sizes that lay in the patch.

"I pick that giant one!" Tex said, running over to pick it up. But just before he did, he said, "Ew! There's a hole in it!" Tex quickly raced to another perfectly perfect pumpkin. But when he got closer, he said, "No fair! Someone took a bite."

The Great Art of Dunhuang exhibition, held at the China Art Museum on the east bank of the Huangpu River, (be) a big hit during the National Day holiday, attracting visitors around the country. On show were some of the most (represent) and rare artifacts from the collection of Dunhuang Academy in Gansu province, which made their first public debut in the metropolis (大都会).

(feature) 168 pieces and sets of cultural relics recognized as national treasures of China, the exhibition welcomed more than 50, 000 visitors during the holiday. One of the (exhibit) was the Shengli Stele, a stone with an inscription recording the beginning of the construction of the grottoes, known as the Mogao Caves. More (impressive) six of the most typical caves had life-size reproductions on display, bringing immersive experience of the Mogao Caves to visitors. According to Zhang Yuanlin, deputy director of the Dunhuang Academy ,the six caves were carefully selected to "sketch out the concise (简明的) history of dunhuang art spanning almost a millennium".

A visitor says, We are not allowed (take) photographs while visiting the Mogao Caves. Thanks to digital technology, we can have a close-up experience with the artworks in these reproduced caves, is more than we can do by visiting the real caves."

Dunhuang, (locate) in an oasis in the Gobi Desert, once served an important trading center along the ancient Silk Road. We hope that by bringing Dunhuang artifacts to Shanghai's wider audiences, it will attract more people to visit Dunhuang in Gansu says an official with the Gansu Provincial Administration of Cultural Relics.

For those people, he is "Gloves" Greenberg. How did he get that3? He looks like any other businessman, wearing a suit and carrying a briefcase (公文箱). But he's4. His briefcase always has some gloves.

In winter, Mr. Greenberg does not act like other New Yorkers, who look at the sidewalk and5 the street. He looks around at6. He stops when he7 someone with no gloves. He gives them a pair and then he moves on, looking for more people with cold8.

On winter days, Mr. Greenberg9 gloves. During the rest of the year, he10 gloves. People who have heard about him11 him gloves, and he has many in his apartment.

Mr. Greenberg12 doing this 21 years ago. Now, many poor New Yorkers know him and13 his behavior. But people who don't know him are sometimes surprised by him. They don't realize that he just wants to make them14.

It runs in the family. Michal's father always helped the poor as he believed it made everyone happier. Michael Greenberg feels the same. A pair of gloves may be a15 thing, but it can make a big difference in winter.

Recently, it was revealed that renowned musician Tino Bao had created a digital version of his daughter, who in 2021 passed away due to a rare disease at the age of 22. With the help of Xiaoice, Microsoft Asia's AI branch based in China, Bao was able to recreate his daughter Bao Rong as an AI-powered virtual figure. Tino Bao, his family and the team went to great lengths to piece together pictures, audio-visual recordings, and narrated memories of Rong. After thousands of trials and errors, they presented the life-like digital human who speaks in both Mandarin and English. Bao has finally launched a company to bring the technological miracle to other families experiencing such loss.

However, this technological achievement has also been accompanied by many controversies. The idea of bringing back a loved one through AI may seem comforting. Still, researchers caution that constantly interacting with an AI version of a deceased loved one could potentially affect the natural grieving process, leaving individuals stuck in a state of denial. This could lead to prolonged grief and other mental health issues. Furthermore, there's a risk that people may become overly dependent on the technology, prioritizing their interactions with the AI version over forming new, real-life relationships.

With the case of Bao Rong out in the open, AI resurrection (复活) has become a business. From simple "talking pictures" that sound nothing like the loved ones to deep fake videos of actors speaking with the faces of those who passed away, the lower end of the market is more "artificial" than "intelligent". Therefore, it is crucial to establish proper regulations and ethical standards to ensure that the use of AI-resurrection technology is safe and responsible.

In the French town of Colleville-sur-Mer on June 6th, US Air Force aircraft flew over the American Cemetery during the commemoration ceremony, in the presence of Army General Mark Milley. It is the final resting place of 9,386 personnel who died fighting on D-Day and in the operations that followed.

Ray Wallace, then 97, a former paratrooper, was among the World War Ⅱ veterans attending the ceremony at the American Cemetery overlooking Omaha Beach in the French town of Colleville-sur-Mer.

On D-Day, his plane was hit and caught fire, forcing him to jump earlier than expected. Less than a month later, he was taken prisoner by the Germans. He was ultimately liberated after 10 months and returned to the US. Still, Wallace thinks he was "lucky." "I remember the good friends that I lost there. So, it's a little emotional," he said, with sadness in his voice. "I guess you can say I'm proud of what I did but I didn't do that much."

On D-Day, Allied troops landed on the beaches code-named Omaha, Utah, Juno, Sword and Gold, carried by 7,000 boats. On that single day, 4,414 Allied soldiers lost their lives. More than 5,000 were wounded. On the German side, several thousand were killed or wounded.

Wallace, who is using a wheelchair, was among about 20 WWⅡ veterans (老兵) who opened the parade (阅兵) of military vehicles on the eve of the D-Day anniversary in Sainte-Mere-Eglise, the first French village to be liberated from Nazi occupation on D-Day, to great applause from thousands of people, in a joyful atmosphere. He did not hide his pleasure, happily waving to the crowd as parents explained the achievements of WWⅡ heroes to their children. Many history fans, wearing military and civilian clothes from the period, also came to stage and celebrate the event.

With his parents looking on, 16-year-old Mack Rutherford took off in Bulgaria's capital, Sofia, in windy but clear conditions. If successful, he would displace (取代) Travis Ludlow from Britain who was 18 when he set the record in 2021.

Only several months ago, his 19-year-old sister, Zara Rutherford, set the world record for the youngest woman to fly solo around the world. Born into a family of pilots, Mack Rutherford has flown hundreds of hours with his dad, Sam, who is a professional pilot. His mother Beatrice is a private pilot. Mack's dream to become a pilot came true in 2020, when he qualified for his license. Now, Mack's lonely journey will take him to 52 countries. His trip kicked off in Bulgaria, because his sponsor is located in Sofia. The first stop will be in Italy. From there he will fly south to Africa, then he will head north to India, China, South Korea and Japan. He will go on to Alaska and continue along the U.S. West Coast to Mexico. Then he will head north again along the East Coast to Canada, cross the Atlantic, stop in Iceland, the U.K. and finish his journey in Sofia after three to five months depending on the weather conditions.

Just like his sister, he will be flying a Shark, a two-seater airplane, which has been specially prepared for such a long journey.

Mack, who is trying to find a balance between schoolwork and his flight, said he preferred to make this trip this year, because "I will be quite busy with a lot of exams next term."

To some people, no matter what life throws at them, they can still find strength in the love from those around them. Luckily, Jackie was one of them.

Jackie was just 17 when tragedy struck. An injury left her paralysed (瘫痪的) when she jumped into a pool. The doctors told Jackie that she would never be able to walk again. The news was heartbreaking for Jackie and her family. All her dreams were lost. Before the accident, she was an athlete, an activist and was always ready for adventure. She loved sports and swimming. But the accident that followed changed her life completely and she didn't handle it well.

Jackie was advised to accept the new normal, but she was not the kind of person to give up easily. She kept going to the beach, parks, and doing whatever she could to make the most out of her life. She turned to exercise as a way to escape the reality of her life, but the lack of mobility caused her to sink into a deep depression that lasted about six months.

Everyone was worried that she'd never be happy again. Until eight years later, on a spring day, Jackie's mother encouraged her to go to the park to take advantage of the warm weather. There, she encountered an engaging young man who approached her unexpectedly. She was initially surprised and cautious, but Andrew's charming personality soon won her over. After hours of conversation, he surprised her by asking her to come to enjoy the sunshine in the park next time. Jackie was shocked but also attracted by his intelligence and passion. Despite her initial disbelief, she agreed and the day marked a turning point in her life.

Jackie and Andrew quickly fell in love, embarking on a romantic journey filled with unforgettable moments. Her past insecurities disappeared, replaced by a sense of joy. Within a year, Andrew proposed (求婚), and Jackie accepted. Their relationship had transformed Jackie's life, bringing her happiness once again. Every girl dreams of their wedding day, and Jackie was no exception.

Look into attending a forest school

We've been doing this for five months now, and it's the best money I've ever spent. One day a week, all of my children spend a day at a certified forest school held in a nearby provincial park., and I've noticed it's made them far more comfortable and willing to play outside overall.

At this time of a year, it's dark in the early evenings, but that shouldn't stop you from sending kids out to play in a safe yard where they're not at risk from cars. Do a quick after-dinner play, or take them for a nightly pre-bedtime walk if you're in a busy urban setting.

Older kids can get a part-time job that gets them outside

Our elderly neighbor asked if she could hire my kids to walk her dog every day, so they do.. It's a great way to get them outside each day, no matter the weather — and they love making money. Other ideas could be a paper route, shoveling snow, or assisting another senior neighbor in some capacity.

On December 17, 1903, the Wright brothers (Wilbur and Orville) achieved their dream. They flew the world's first power-driven and heavier-than-air machine. This memorable feat took place at Kitty Hawk, North Carolina on a cold windy morning.

The dream started with an idea that was planted in their minds by a toy given to them by their father. In the words of the boys, "Late in the autumn of 1878, our father came into the house one evening with some object partly hid in his hands, and before we could see what it was, he threw it into the air. Instead of falling to the floor, as we expected, it flew across the room till it struck the ceiling, where it flew a while, and finally sank to the floor." This simple toy made of bamboo and stretched rubber bands fascinated the Wright brothers and sparked their lifelong interest in human flight.

The Wright brothers were great thinkers. They enjoyed learning new things. Initially, they recycled broken parts to build a printing press and opened their own printing office. Their interest moved to bicycles and in 1893, they opened the Wright Cycle Company where they sold and repaired bicycles. But Wilbur (the older brother) had his mind set on something more exciting. He decided to seriously pursue flying.
