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.

When my mom announced that my dad had fixed the old car in his garage, I felt excited—I had wheels! I called my friend Steph and made plans to have dinner at her house the next day.
The following morning, I woke up early and put on a black skirt and jacket. “Aren’t you dressed too lightly?” Mom asked. “There’s a snowstorm coming.” “I’ll be inside,” I replied as I headed out.
As I began the forty-minute drive, I was in high spirits. However, halfway there it started to snow like mad. Cars slowed. The sound of a siren announced the approach of an ambulance and I pulled aside to let it pass. As I inched back into my lane, the traffic light ahead turned red. I stopped.
When the light turned green, I pressed on the gas, but the old car died. I tried to start it. One click, then nothing. Before I could do anything else, two young men raced over from the nearby sidewalk. I rolled down my window a little.
“Give us a second,” one of them said, “We’ll help you out of here.” Soon, they began pushing the car. With their guidance, I steered into a parking spot in front of a grocery store. “You’ll be fine now,” they said, and before I could even thank them, they walked into the grocery store.
The snow was falling faster now. I called Steph on my cellphone to cancel our plan. Next, I called my parents to come and get me. Now all I had to do was wait, but I was very hungry and cold. I sighed, regretting not taking my mom’s advice.
Just as I sat waiting in the car, I noticed a man walking towards me. It was one of the men who had just helped me. I rolled down the window at once.

Every October, my neighbor Ollie and I would enter the Halloween costume contest (服装比赛) in our neighborhood park．And each year the theme was different, such as “Superheroes” or “Far m Animals”．But this year’s theme was not so specific．It was just “Be Creative”．
Walking home along the road lined with tall trees, the two of us had a heated discussion about what “Be Creative” meant．We looked back on the themes we had really enjoyed．For “Superheroes”, we made costumes of Super-Force Flying Eagle．And for “Farm Animals”, we were dressed as a cow and a horse．Ollie even put a pair of wings for the horse, saying that he’d love to see a “flying horse” eating grass with a cow on the farm．
“Now that’s the creative spirit we need for this challenge!” I said．“Maybe, since we don’t know exactly what we want to be yet, we should start by choosing some cool costume-making materials.”
Just at that moment, a falling golden leaf happened to have landed on Ollie’s shoulder．“I’ve got it!” Ollie said joyfully, picking up some fallen leaves from the ground．“We can make costumes out of leaves and pretend to be trees．I can ensure, no one will be a tree as great as me.”
“Oh, that’s wonderful!” I said．“I like your creative idea and I have just got a perfect way to be another tree.”
We filled up two bags with different kinds of leaves: Ollie’s grandma, Abuela, an experienced tailor (裁缝), helped us with tons of excellent costume-making supplies and we started to work．When we were done, we each tried on the self-designed costumes and they were really wonderful．On the morning of the contest, we got up early and spent hours making preparations．We arrived at the park early and waited for our turn nervously and eagerly．

8 . 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.

10 . While screen time is known to affect sleep, new research suggests that interactive (互动的) activities, such as texting friends or playing video games, put off and reduce the time spent asleep to a greater degree than passive (被动的) screen time like watching television, especially for teens.
The team studied the daytime screen-based activities of 475 teenagers using daily surveys. They asked the teens how many hours they had spent that day communicating with friends through social media and how many hours they spent playing video games, surfing the internet and watching television or videos. Finally, the researchers asked if they had joined in any of these activities in the hour before bed.
Next, the team measured their sleep time for one week. The researchers found that the teens spent an average of two hours per day communicating with friends via social media, about 1.3 hours playing video games, less than an hour surfing the internet and about 1.7 hours watching television or videos. For every hour throughout the day that they used screens to communicate with friends, they fell asleep about 11 minutes later averagely. For every hour to play video games, they fell asleep about 9 minutes later. Those who talked, texted or played games in the hour before bed lost the most sleep: about 30 minutes later.
Interestingly, David, lead author of the study, said the team found no obvious relations between passive screen-based activities and sleep. “It could be that passive activities are less mentally exciting than interactive activities,” said Anne, co-author of the study. “It’s a tricky situation,” she said. “These screen tools are really important to everyone nowadays, so it’s hard to put a limit on them, but if you’re really looking out for a teenager’s health and well-being, you might consider limiting the more interactive activities, especially in the hour before bed.”
