1 . Have you ever imagined an insect-inspired robot, which weighs less than a gram, could one day help out in surgery (外科手术)?
Scientists have designed this small, “insect-bot” called mCLARI that can control and even change its body shape as it travels in different environments to fit through gaps. It’s 2 centimeters long, weighs less than 0.97 grams and can travel at a speed of 6 centimeters per second.It’s the smaller, faster replacement to CLARI, which was designed by the same team.
“Because of the robot’s small size and ability to change shape, we expect usage of this technology in four important areas,” the lead author Kaushik Jayaram said. These include disaster (灾害) response , check on high-value objects, environmental monitoring and medical treatment.
“In the long term, we hope such robots will be used more widely in moving through human bodies and performing surgeries that can’t be easily done at present,” Jayaram said. With mCLARI, Jayaram’s team is moving closer to creating robots that can fit in different environments—just like the insects they’re inspired by.
The mCLARI robot has four legs and can move in narrow spaces by changing between running forward and side-to-side and can use different speeds in human bodies. Its legs are joined to its body through joints (关节), which enables mCLARI to change its body shape based on the environment it is in. For example, its legs can be lengthened up to 50% in certain spaces.
As follow-up work, the scientists want to give mCLARI more power and sensing ability while helping the surgeries. “We are also excited about understanding the effect of shape change on improving functions of robots,” Jayaram said. “And this is sure a great one-step forward of the technology. The robot will have entered the market by 2025 and will bring greater benefits to mankind, especially in medical treatment.”

2 . A new study, led by Dr. Rebecca Stone, has shown that children as young as four years old eat 79% more calories when they are bored, compared to when they are in a normal mood (情绪) .
The researchers have explored the behaviors that make children more likely to eat when they experience negative emotions. Often when children experience bad emotions such as boredom or sadness, caring adults will use food to soothe them. However, this behavior, known as emotional feeding, appears to increase the possibility of children eating more when they are in low spirits. As time passes, too many calories intake will have a significant effect on children’s health both mentally and physically.
Dr. Stone stresses that the experience of boredom is important in the development of children’s sense of self and creativity, so she does not recommend that children should avoid being bored. Instead, she suggests children learn to experience boredom without turning to food. She also suggests that parents turn their children’s attention away from food when they feel bored, or restructure the home food environment to make it less likely that children turn to food in response to being bored.
While there do appear to be individual differences between children in terms of their eating when bored, it is helpful to know that the feeding practices that adults use around food might shape the likelihood of this happening. Although it is attractive to use food as a tool to help children, emotional feeding might lead to greater emotional eating in the future. It is important for parents and caregivers to be aware that this short-term fix could create future problems.
It is hoped that, on the original basis of the study, the team will deeply explore other negative mood states in children and offer advice and support for families to find more effective ways to manage challenges around children eating behavior.

4 . Mathea Allansmith isn’t your typical grandmother. She’s the oldest woman in the world to have completed a marathon. She was 92 years 194 days old when she crossed the finish line at the 2022 Honolulu Marathon, setting the record for the oldest female to complete a marathon.
Mathea, now 94, of Koloa, Hawaii, USA, stays in shape all year round by running seven days a week, no matter what the weather is. Come rain or shine, she covers 36 miles every week, even when she’s on holiday. The retired doctor didn’t take up running until she was 46 years old —after a friend suggested running two miles per day.
“The Honolulu Marathon is my favorite marathon mainly because it doesn’t close the gate at a certain time, which allows even the slowest runner to finish the race,” she said. “It’s one of the best races. Fantastic registration (注册), set-up and management make it a joy to run the race.”
Mathea, who doesn’t allow her age to slow her down, thinks she is the happiest person when she’s on the road. She enjoys running for miles and waving and saying hello to the people she passes. To stay in shape, Mathea keeps a steady training routine (惯例) . “I train all year round but increase the mileage 18 weeks before a marathon,” she said.
Mathea said it was her career as a doctor that allowed her to understand how her body and mind respond to diet and exercise. “I see the direct relation between moving and health,” she said. “It is important to reduce stress rather than ignoring it without a plan on how to do so. Of course, exercise of any kind is a natural stress reducer.”
Mathea thought getting through the finish line and winning a Guinness World Record title was the excitement of her life. “My family completely surprised me after the 2022 Honolulu Marathon, in which I achieved the world record, by wearing matching T-shirts stating my achievements,” she said.

5 . In China, tea has become an important part of everyday life for thousands of years. As the tea-processing methods and tea culture have evolved over the years, tea sets have also changed to meet the practical and cultural needs.
During the Tang Dynasty(618~907AD), tea leaves were traded across the country and Asia. For the convenience of transportation and storage, tea leaves were pressed into bricks. To prepare tea, drinkers had to cut them into small pieces and boil them in heat-resistant teapots.
By the Song Dynasty(960-1279), drinkers started to turn the hard bricks into powders (粉末) that could be whipped (搅打) in a cup with boiled water. This whipped tea is most commonly associated with Japanese tea ceremonies today.
By the 1500s, tea bricks gave way to the form of rolled leaves. This innovation led to the invention and use of teapots as we know them today. These teapots originally came from the Yi Xing region of China and were soon copied throughout the world. Then Japanese teapot-makers moved the handle from the side to the top of the teapots.
Tea finally reached Europe in the 1600s, along with the necessary tea sets made in Japan and China. As English teapot-makers began to adapt the tea sets to their country men’s tastes, they eventually added a handle to the tea bowl because of the English habit of drinking hot black tea, which was consumed at higher temperatures. The size of teacups also grew to accommodate milk and sugar in their tea.
By the early 1900s, innovations in tea drinking became an American affair. The most revolutionary one was the tea bag, which was accidentally commercialized by Thomas Sullivan. He had been sending customers tea wrapped in silk bags. Rather than take the leaves out of the bags, as Sullivan intended, the customers put the bags into their teapots instead. Not only did the tea bags push the teapot back to the sidelines of tea service, they were also too large for teacups and led to the modern practice of drinking tea from mugs.

7 . From self-driving cars to carebots (care+ robots) for elderly people, rapid development in technology has long represented a possible threat to many jobs normally performed by people. But experts now believe that almost 50 percent of occupations existing today will be completely unnecessary by 2035 as artificial intelligence (AI) continues to change businesses.
“The next fifteen years will see a revolution in how we work, and a revolution will necessarily take place in how we plan and think about workplaces,” said Peter Andrew, Director of Workplace Strategy for CBRE Asia-Pacific. A growing number of jobs in the future will require creative intelligence, social skills and the ability to use artificial intelligence.
The report is based on interviews with 200 experts, business leaders and young people from Asia-Pacific, Europe and North America. It shows that in the US technology already destroys more jobs than it creates. But the report states, “Losing occupations does not necessarily mean losing jobs—just changing what people do.” Growth in new jobs could occur as much, according to the research. “The growth of 20- to 40-person companies that have the speed and technological know-how will directly challenge big companies,” it states.
Another study by Pew Research Centre found 52 percent of experts in artificial intelligence and robotics were optimistic about the future and believed there would still be enough jobs in the next few years. The optimists pictured “a future in which robots do not take the place of more jobs than they create.”
“Technology will continue to affect jobs, but more jobs seem likely to be created. Although there have always been unemployed people, when we reached a few billion people, there were billions of jobs. There is no shortage of things that need to be done and that will not change,” Microsoft’s Jonathan Grudin told researchers.

8 . A small study out of Skidmore College examined the advantages of morning vs, evening exercise for both women and men. Paul, professor for health at Skidmore, led the study.
“We had the groups divided into evening and morning groups,” he says. “We found women and men answered differently to different types of exercise depending on the time of the day, which surprised us.”
The study showed that for women who want to lower blood pressure (血压), the risk of heart disease or reduce fat, morning exercise works best. Those women hoping for upper body muscle (肌肉) gains or mood (心情) improvement should consider evening exercise. For the men, the findings were somewhat different: Evening exercise lowers blood pressure, the risk of heart disease, and feelings of tiredness. But similar to women, they burn more fat with morning exercise.
“For many people, the best time to exercise will depend on their chronotype,” says Heisz, author of Move the Body, Heal the Mind.
“Chronotype is your body’s natural habit to sleep at a certain time—it’s what decides whether you’re a night owl or an early bird. For the 25% of the population that considers themselves a night owl, getting both enough sleep and enough exercise can be difficult,” adds Heisz.
He continues, “Sleep—which provides your body the necessary time to recover (恢复) and make gains from exercise—should always be the first choice. When it comes to exercise, regardless of research on the advantages of certain exercises at particular times of the day, your results will not be good if it doesn’t allow enough time for sleep.”
1. What can women get by doing evening exercise according to the study?| A．A fat loss. |

9 . In a world where acts of kindness often go unnoticed, a good story that has been discovered reminds us of the power of care and the effect it can have on someone’s life.
It all started with a “Kindness Week Challenge” given to Brennan by his 8th-grade teacher, Ms. Watkins. Little did he know that this challenge would lead to a wonderful friendship with 84-year-old Ms. Ann.
Brennan’s promise to send his little attractive things every day for a week developed a habit of checking up on Ms. Ann and sending gifts regularly(定期地), long after the challenge was over.
Their friendship has now lasted for over five years, and Brennan still visits Ms. Ann every month with flowers, cakes, chocolates, cards and more.
They talk about everything from his high school life to his college goals. The pair has found that they share a common love of chocolates. Ms. Ann always hopes to hear about what he’s doing and loves to share her own stories from a different time. They have become the best friends, with Brennan treating her as his great-grandmother.
Brennan’s mom, Traci, takes pride in her son. She said, “The best thing a teenager can do is to take care of the elderly. I’m so glad my son has added more sunshine to Ms. Ann’s life. I hope he always remembers the joy he’s brought her, and his fun talks with her, keeps his kind heart, and thinks of others.”
Ms. Ann’s daughter Emma, with her husband Gould, has a 2-year-old son. They are thankful for Brennan’s friendship as they cannot always be with Ms. Ann. Brennan’s kind heart has brought more sunshine into Ms. Ann’s life, and her encouraging words have helped to inspire(启发)him in return.
