They called him “Donnie the Dung Beetle”. Donald didn’t mind the comparison, as he knew that African dung beetles(粪金龟)were known for moving things a thousand times their own body weight. However, his classmates in Mrs. Beecher’s third-grade class probably didn’t know this fact. Nobody knew insects like Donald did, and he figured that being compared to a dung beetle was not a praise.
One day, Richie made fun of Donald, pointing towards a container under the window where a small brown ball hung from a branch. Donald tried to explain that it was an egg case of a praying mantis(螳螂), and the exciting part would be when the eggs hatched. But Richie didn’t understand, and neither did most of the other kids. Donald had brought the egg case from his backyard and was excited when Mrs. Beecher agreed to make it their class project. He thought having an insect as a class pet might finally give him something to talk about with the other kids. But after two months of staring at a lifeless brown ball, Donald began to lose hope.
During science class one day, Mrs. Beecher announced they would start by writing in their journals. As Donald opened his journal, a left over particle from his lunch rolled across the page. When he went to brush it off, he realized it wasn’t a particle at all —it was a tiny praying mantis, barely the size of a grain of rice! Donald bounced out of his seat, crying out that the eggs were hatching.
Suddenly, chaos erupted in the classroom as more baby mantises started appearing everywhere. Kids were jumping out of their seats, screaming and waving their arms. Mrs. Beecher quickly took charge, asking why the lid of the container was off. Richie, who was supposed to check on the container that day, had forgotten to put the lid back on.

__________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________At the end of my junior year, election for student body officers caused quite an excitement among students. It appeared that Debbie would run unopposed for president. Talking among a group of dissatisfied girls, I whispered, “There must be someone who’d run against her.”
Suddenly Liz focused her attention on me. “Why not you?”
“Me? No way. I work after school. I can’t stay for all those meetings. ”
My closest friend, Linda, smiled, “Why not? Just think how great our senior year would be! You could get a real senior trip approved and get better bands for the dances. ”
My little group continued to ignore my protests as they imagined the wonderful changes I could make. By the end of the week, they’d gotten enough signatures to put my name on the ballot (选票).
Debbie and I had very different campaign styles. Because I was always skipping around, I earned the name “Rabbit”. Signs soon appeared around campus with the slogan (口号) “Make your votes count with Rabbit!” My platform aimed for more fun and less restrictions. We wore uniforms and I advocated more free dress days and a broader interpretation of what was acceptable on regular dress days.
My opponent, on the other hand, avoided any implication of silliness on her posters. Catchy slogans had no place in her serious campaign. What she offered was the opening Lawn to all students and a reformatting of the yearbook that would mix ninth through twelfth graders rather than highlight seniors in oversized photos. Gone would be the yearbook with seniors’ quotes and many exciting activities. Lowerclassmen (低年级生) loved Debbie’s idea; would-be seniors, however, were angry.
My classmates supported me and were confident they could persuade enough lowerclassmen to vote my way. Each day I got reports of a few more of lowerclassmen coming to my side.
On election day, I felt fairly confident. I was even looking forward to quitting my job and focusing on school politics.

You see a shopper trip over in a busy street. Someone else can help. That’s what you tell yourself. This is the bystander effect in action — the dilution (淡化) of responsibility in the presence of others — and it has been demonstrated in many past studies.
But life is complicated and psychologists have seen exceptional circumstances. Two experiments were conducted by Marco van Bommel and his team using an online chat room for people with extreme emotional problems. Eighty-six students were logged into the forum (论坛) and shown five messages from troubled users. They were told to write a reply if they wanted, but it was entirely up to them.
Basically, participants could see their names on the screen alongside others’ names. A counter also told them if the forum was quiet, with just one other person logged in, or busy, with 30 others online. This arrangement reproduced the classic Bystander Effect-participants were less likely to post replies with more people logged in. However, when the researchers cued (提示) self-awareness by highlighting participants’ names in red on the screen, they posted more replies on a busy forum.
A second study was built on these findings, but this time self-awareness was raised by the presence, or not, of a computer web-camera. Over 100 participants took part. Although told the camera wouldn’t be used until later, those with cameras were asked to check the camera’s indicator-light during the study. The Bystander Effect was reproduced when web-cameras were absent-on busy forums participants posted fewer replies to needy users. By contrast, those cued to be self-aware by the web-cam actually wrote more replies.
Nearly any online community can benefit from the research. The ability to turn hesitant bystanders into eager helpers is a recipe for engagement and collective benefit. As in the research, simple design cues could be integrated to help online users remember they are visible to the community. For example, the size of profile images and specific on-site reminders can be used to highlight how users see themselves within the community.

Students’ Time Spent on Physical Exercise Weekly
Nowadays, many students are aware of the significance of physical exercise, although the time they spend on it varies.
_______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________5 . When delivering medications to patients, one of the most effective methods is direct injection (注射) into the bloodstream using a needle. But this can be an uncomfortable experience, especially for kids or adults with a fear of needles. While patients do have the option to take oral pills instead, drugs containing large molecules (分子) are not absorbed effectively this way.
Now, inspired by octopus suckers (章鱼吸盘), researchers from China and Switzerland have designed a needle-free alternative: a tiny, drug-filled, cup-like patch (贴片) that sticks to the inside of the cheeks. The device is easily accessible, and it can be removed at any time and the drug gets absorbed through the lining of the inner cheek, the team reports in a paper in Science Translational Medicine.
To test the design, the team 3D printed the suckers. They loaded each with the drug and stuck them inside the cheeks of three beagles, a kind of dog which has a similar inner cheek lining to humans. For comparison, they also delivered the drug to beagles via a pill. After three hours, the team found that drug blood concentrations in dogs with the patch were more than 150 times higher than in the dogs that took a tablet. They also found patches worked effectively for drugs with large molecules.
40 healthy human volunteers self-applied water-filled patches to see how well they would stay on while talking and moving their mouths. After 30 minutes, only five of the 40 patches had fallen off, which was because of improper placement. Most volunteers said they would prefer a patch over injections for daily applications.
Still, the team only tested the patch for a short time so they would need to find out what would happen if it was used repeatedly. They’d also need to determine which drugs would work with the technology: the target is large molecules, such as those used to treat obesity or osteoporosis, but they can’t be too large to fit in the cup.

9 . 3M and Discovery Education announced Sean Jiang from Gilman School as one of the top ten finalists from across the nation for the 2023 3M Young Scientist Challenge. It’s a competition that encourages students to identify an everyday problem and submit a video showing the science behind the solution he or she came up with.
14-year-old Jiang decided to help those who can’t see. Blind people had a hard time navigating (导航) objects that are medium to far range. So Jiang wanted to design something to give them a heads-up on obstacles (障碍) that may be incoming.
Jiang’s inspiration came from the powers of the hearing system. “I learned in school that bats and whales are able to use echolocation (回声定位) to help them navigate and just use their sense of hearing and I also saw on YouTube some very skilled blind people that use echolocation to help them walk,” said Jiang.
Jiang started with a virtual reality setting and then made it a reality. His creation uses a depth camera that can detect how close objects are, thus giving enough time to dodge the obstacles. When a blind is walking with the device, the sensor of the depth camera gathers the information regarding the obstacles’ position and distance. Then the AI system in it will turn the distance data into musical sound guidance. This could significantly increase the walking speed of a blind person as well as decrease the number of obstacles they hit.
Some other similar programs were alright at finding objects that were in close range, but Jiang still wanted the blind to experience the world even fuller so they were able to see stuff that was much further away than their circle of reach.
In October, the top ten finalists will compete in person in Minneapolis for the title of “America’s Top Young Scientist” and a $25, 000 prize.
