1 . Dorothea Dix was born in 1802 in Massachusetts. When she was 12 years old, she left her unhappy home to live with her grandmother in Boston. There Dorothea went to school and was so quick at her lessons that two years later she went back to Worcester, Massachusetts and taught in a school for little children. She was only fourteen and rather small for her age. Anyway, she proved herself a good teacher, and the children loved her and respected her. In 1821, she opened a school for girls in Boston.
Gradually, her health broke down, and she began to think that she could never work any more, but after a long rest in England, she came back to America and did something far greater than teaching. She went through the whole country where she first observed the inhumane treatment of the mentally ill. During Dorothea’s traveling for nearly two years throughout the state, and meeting similar conditions, she always spoke kindly to the ill-treated, but she spoke wrathfully to the men who ill-treated them. In January 1843, she submitted to the Massachusetts legislature (立法机关) a detailed report of her fully documented findings.
In the next 40 years Dorothea inspired legislators in 15 US states and in Canada to establish state hospitals for the mentally ill. Her continuous efforts directly affected the building of 32 institutions in the United States. When the Civil War broke out, she went straight to Washington and offered to nurse the soldiers without pay. She hired houses to keep supplies in and bought an ambulance. She gave her time, strength and money to her country.
Dorothea Dix has been called the most useful woman of America. She is an, American educator, social reformer and humanitarian whose devotion to the welfare of the mentally ill led to widespread reforms in the United States and abroad.

2 . Soap (肥皂) might seem like a reasonable way to avoid mosquito bites (蚊子叮) on the basis that if mosquitoes can’t smell you, they can’t bite you. However, a recent study has found that rather than protecting you, certain soaps might actually make you more attractive to mosquitoes.
In the study, conducted at Virginia Polytechnic Institute and State University, four volunteers were asked to wear a sleeve before and after washing with four different brands of soap. The researchers then watched female mosquitoes as only females feed on blood landing on the fabric sample to show their preference. They found that some people washing with some brands of soap, increased their attractiveness to mosquitoes, while washing with other brands of soap tended to repel (驱除) mosquitoes. The repellent effect of some soap may be due to its coconut scent, as coconut oil is known to act as a natural mosquito repellent. The reason behind this attraction is believed to be related to mosquitoes’ sugar intake. When mosquitoes are not feeding on blood, they add their diet with plant juice or sweet water from flowers, “The fact we are taking those flowery and fruity smells and putting them on our bodies means that now the same object smells like a flower and a person at the same time,” said Clément Vinauger, who led the study. It would be like waking up and smelling the smell of coffee and bread, very attractive.
Interestingly, the effects of the soap varied among people, possibly due to the interaction (相互作用) between the soap and each person’s unique body scent. “It’s remarkable that the same person that is extremely attractive to mosquitoes when he is unwashed, but he becomes even more attractive to mosquitoes with one soap, and then become repellent to mosquitoes with another soap,” said Vinauger. Further research is needed to better understand the interaction between different soap and body scents, as well as to develop more effective mosquito repellents.

3 . Plastic is everywhere, from the Arctic ice to vital organs in the human body. In fact, previous estimates suggest that the average person swallows a credit card-worth of microscopic plastic particles(颗粒) every week. But new research shows that this could actually be an understatement.
Microplastics are plastics smaller than 5 millimeters, found in industrial waste, beauty products, and formed during the degradation of larger plastic pieces. Over time, they break down into even smaller nanoplastics. These tiny particles can pass through our intestines and lungs into our bloodstreams, reaching vital organs like the heart and brain.
While the idea of eating plastic is unsettling in itself, the major concern here is that these plastic particles contain chemicals that can interrupt our body’s natural release of hormones, potentially increasing our risk of reproductive disorders and certain cancers. They can also carry toxins(毒素) on their surface like heavy metals.
In the past, researchers have shown bottled water can contain tens of thousands of identifiable plastic fragments in a single container. However, until recently, only the larger microplastics were detectable with available measuring tools, leaving the area of nanoplastics largely a mystery.
Using Raman microscopy (显微镜学), capable of detecting particles down to the size of a flu virus, the team measured an average of 240, 000 particles of plastic per liter of bottled water, 90 percent of which were nanoplastics, a revelation 10 to 100 times larger than previous estimates.
These plastics likely originate from the bottle material, filters used to “purify” the water, and the source water itself. “It is not totally unexpected to find so much of this stuff, ” the study’s lead author, Columbia graduate student Naixin Qian, said in a statement. His team hopes to expand their research into tap water and other water sources to better inform our exposure to these potentially dangerous particles. “The idea is that the smaller things get, the more of them I reveal, ” he added.

4 . The design theory behind a pair of tiny robots may one day find its way into environmental monitoring, as well as search and-rescue tasks. Modeled after a water strider (水黾), an insect, the two robots each weigh in at 8 and 55 milligrams, and may mark the smallest, lightest, and fastest fully functional micro-robots in the world, according to Washington State University (WSU).
Developed by a team of WSU researchers, the robots’ tininess largely relies on a material known as a shape memory alloy (合金). Although shape memory alloys change form when heated, they can “remember” their original shapes and return to them after cooling. Because of this, the two micro-robots do not require standard motors, and they use light and small ones instead of bulky moving parts.
Both the robots’ motors are each made up of two shape memory alloys, allowing them to move their fins as fast as 40 times a second while also lifting over 150 times their weight. “They’re very technologically sound. The development of the very lightweight robots opens up new possibilities in micro-robotics,” said Conor Trygstad, a material engineering PhD student and study lead author. “Although the robots are impressive when compared to other robots, the pair still fall behind their biological relatives’,” Trygstad said. They can currently move at a speed of about six millimeters a second; a water strider, by comparison, speeds along at about a meter per second. For now, the robots also require wired (连线的) power sources, thus seriously preventing any real-world applications for the moment.
Going forward, however, the team plans to copy other small insect species while also creating a new water strider robot which can move at a higher speed. Depending on using small batteries could also greatly increase the robots’ areas of use, If the breakthrough designs continue improving, similar micro-robots could one day be employed to monitor hard-to-reachor dangerous environments.

7 . Dallas-based Knit Wits is made up of a group of grandmothers with a strong love for knitting (编织) who tum their love for crafting into a purposeful attempt. Meeting regularly, they pour their collective love into every stitch (针法) they make. The group has been working for over ten years, meeting every Friday, to support organizations that help others, locally and around the world. Over the years, they’ve crafted thousands of items insupport of the important things.
Recently the Knit Wits member Mary Ann Stover was inspired to have the group knit hats for infant (婴儿) patients with heart disease at Children’s Health Hospital. The hats, each a unique work of art, designed with holiday themes, reflect the skill of the Knit Wits. More importantly, the special of Knit Wits is its understanding of the emotional effect these small objects can have on the infants experiencing medical treatments.
Bealle, a certified child life specialist at Children’s Health Hospital, explained how the hats are making a difference to the tiny patients and their families. “Caregivers are able to wear the hats on their body to move their smells before placing the hats back on the infants, encouraging connecting and making the infants less stressful,” he said.
Throughout the infants’ admission, many holidays are celebrated. At times, some infants are seriously ill and unable to dress up for holiday photos the families have planned. Thanks to the donations from Knit Wits, the hospital team is able to prove the family with a suitable themed infant hat the family can use for their photos and holiday celebrations.

8 . Ms. McIntyre, 38, worked as a publisher. She suffered brain cancer and her health got worse despite some medical treatment. But she realized that in a way, she was luckier than some other people. She had insurance to help pay for her medical care. But Ms. McIntyre and her husband, Mr. Gregory, knew that many people with cancer face tough decisions because of the costs of medical care and wind up owing far more than they can pay.
Though her health was failing, Ms. McIntyre decided to help pay off the medical debts of as many people as she possibly could. The couple began donating money to a group called RIP Medical Debt, which is committed to working to pay off the unpaid medical debts of others. The group can pay off medical bills for about 100 times less money than they cost. In other words, for every 100 donated, the group can pay off 10,000 in unpaid medical bills.
Unfortunately, Ms. McIntyre passed away before long. Mr. Gregory posted a message for Ms. McIntyre on her social media accounts. “If you’re reading this, I have passed away,” the post began. Then the post explained, “To celebrate my life, I’ve arranged to buy up others’ medical debts and then destroy the debts.”
The couple had set up a page on a website to raise money for this purpose. They had hoped to raise about $20,000. Nevertheless, Ms. McIntyre’s last post attracted a lot of attention. The donations on her web page quickly passed the total goal. In less than a week, the site had raised 10 times more than expected and the donations are still coming in. By November 22, 2023, Ms. McIntyre’s web page had raised over $627,000, or enough money to pay off about $60 million in medical debts.
Mr. Gregory planned a special event in December to celebrate Ms. McIntyre’s life and to announce how many millions of dollars of medical debts her efforts had paid for.

9 . In the northernmost edge of Colombia sits the coastal town of Acandí. Access to the town is only by water or air; there is no road that leads there. The residents there are faced with the struggles of balancing livelihoods while protecting biodiversity.
In the past, traditional community fishing methods, passed down by the elders, focused on the reasonable fishing and management of resources. However, the introduction of large-scale trawling vessels(拖网渔船) decades ago gradually depleted the area’s fishing resources, leading to damage to marine(海洋的) life seriously.
Jesús Antonio Julio Cuestas, who serves in the region’s conservation and management of marine resources, stresses the bad impact of these developments and calls for new fishing techniques. “Fishing and conservation co-exist as long as we have good management practices and reasonable use of our fishing resources,” says Cuestas. He and other officials actively monitor fishing activities in Acandí. Each morning, they visit the fish markets to gather data on fishery resources—including prices and sizes—to monitor the state of the local fishing industry.
Along with Cuestas, the fishers work to reduce their impact on the marine ecosystem. By changing fishing methods and adopting new practices, they aim for a more balanced approach to fishing. “This year the local fishermen have not used the trawl net s that were causing the death of the leatherback sea turtles,” explains Cuestas proudly. Changes include the efforts of boats to protect the seagrass that serves as feeding grounds for marine life and an end to fishers throwing net s where turtles lay their eggs.
This marine reserve in Acandí, Cuestas believes, is their greatest treasure. He attaches great importance to working together with local residents to improve the quality of life while preserving the marine ecosystem. By doing so, he imagines a picture where individuals from the fishing community can pursue various careers, such as engineers or lawyers, proudly stating that they are the products of the fishing tradition in Acandí.

10 . Lots of kids like to talk about sports, but Joseph D’Avirro talks about sports like a professional host in a show called Sliders & Curveballs. The 9-year-old from Newington, Connecticut is a natural at sports talk and has been broadcasting the show—which is about baseball, basketball and other sports—with his dad, Mike D’Avirro, since September 2019.
The D’Avirro started the broadcast after two former college roommates of Mike died, which made Mike want to spend more time with his son. Then the idea came to him. So far, they have done about 50 programs. Joseph’s favorite is when the father-and-son team interviewed Jim Calhoun, the coach leading the Connecticut Huskies to three national titles. They have also interviewed important sports authors.
The father and son make about one 30- to 40-minute podcast each month. They prepare for the podcasts by deciding on the questions they want to ask the guest. Joseph asks half of the questions, and Mike handles the other half. Joseph reads his questions again and again to get them in his brain well. It is a lot of work, but Joseph says it is “a lot more fun than homework”. Joseph has also learned to speak up and speak clearly. He has to listen and to go with the flow of the conversation. For example, he said, “If the guest is talking about sports in the 1990s, you have to think about sports in the 1990s.”
When asked how long he and his dad will continue doing the show, he answered, “Until my dad starts growing gray hairs.” Joseph has other ambitions when he grows up—to be a sports player, a sports broadcaster or to own a basketball team. Those are big dreams, but Joseph is already living a dream: talking sports and spending time with his dad.
