In August, James was freed as part of a(n)4 exchange. After arriving home, he told his family he wanted to be5. Then James hid in his own room. Wood shavings appeared outside his door to be taken away. Three months later, James' door opened6. His family gathered below the stairs, staring in7. James wasn't stumping (笨重地走) toward them on the former artificial leg. He should be8! James had created his own artificial leg! James had been studying9 in college before, convinced he could do a better artificial leg. James carved a foot and shaped leg pieces, until he'd created a comfortable leg that bent at both the ankle and the knee. They were10 when he walked.

Making improvements in his design, he started an artificial leg production company. James retired in 1905, but retirement didn't keep James from11 his life's work. James read reports about new battlefield12 of amputees (被截肢者) to develop new techniques. During the war, his company received contracts from England and France. The company he founded is today one of the most famous13 of replacement legs in the world.

Looking back upon those days in hospital, James wrote, "In a flash, life's fondest hopes seemed14." He continued, "Today I am thankful for what seemed to me nothing but a15 of fate (命运) then, but it was to prove instead a great opportunity."

As plastic pollution worsens, bioplastics — plastics made from natural materials — are gaining popularity, but they still account for only 0.5% of the more than 400 million tons of plastic produced every year. That is because bioplastics have lower mechanical strength than oil-based plastics and are difficult to apply easily in common production processes.

The Chinese team developed a method to produce plastic from cellulose, the fibrous component of bamboo. They first treated bamboo by adding zinc chloride (ZnCl₂) and a simple acid. In experiments, the team said bamboo-based bioplastic showed mechanical strength outperforming that of conventional plant-based bioplastic. In tests of mechanical and thermal stability and shapeability, bamboo-based bioplastic demonstrated its potential as an industrial alternative.

The development of bamboo-based bioplastic by researchers at Northeast Forestry University represents a significant advancement in the pursuit of sustainable development. With its impressive mechanical properties and biodegradability, bamboo-based bioplastic stands out as a promising candidate for reducing plastic waste and reliance on oil.

However, the path to future widespread adoption requires overcoming challenges related to production scalability (可扩展性) and market acceptance. As industries explore the potential of bamboo-based bioplastic, the question remains: Can this innovation truly replace traditional plastics and transform our approach to sustainable production?

The results are not just about finding who might be good at music early. The study shows that when the brain learns skills in one area, it can affect learning in another. Sarah Creel, the lead author from UC San Diego's Department of Cognitive Science (认知科学系), said, "A big question is whether our mental abilities are separate. For example, do we have special brain systems only for language? Our research suggests the opposite — there's a kind of interaction and we can use cognitive abilities in different areas."

The researchers did two experiments with young Mandarin learners and English learners. They tested 180 children on tasks about pitch patterns and timbre (音色). In the timbre task, Mandarin-speakers and English-speakers did similarly. But in the pitch task, Mandarin-speakers outperform English-speakers.

Mandarin is a tone language. The authors think that paying attention to tones helps young Mandarin speakers notice pitch in music better. Gail Heyman, a co-author from UC San Diego's Department of Psychology, said, "This shows that the language you speak affects how you understand music. It supports the idea of cross-domain (跨领域) learning."

The study's co-authors wrote, "We show for the first time that learning a tone language is connected with better musical pitch processing in young children. This is important for neuroscience (神经科学) and behavior, and our research can help design brain training programs."

But Heyman and Creel advise: Don't stop your child's music lessons to focus only on language, or language lessons for music. To be good at music, you still need to study music. And learning another language is good in itself, whether it makes you a better musician or not.

I was sent to him as a boy because I used language clumsily (笨拙地). My sentences were awkward, full of thorny (晦涩的) phrases. Instead of criticizing me. he placed a worn dictionary between us. "This is the seed catalogue," he said, his finger, tracing the words. "But knowing the name of a seed is different from knowing how to make it grow."

One afternoon, he pointed to the word "effervescent". "This one," he said, "is a bubble. It belongs in a description of a stream in sunlight, or a child's laughter. Plant it in a sad sentence, and the bubble will pop." Then he showed me "sombre," which he called "a deep-rooted thing, needing the shade of a serious thought."

Under his care, I learned to feel the weight and texture of words. I learned that "home" is a strong oak tree, offering shelter, while "house" is merely its timber (木材). That "lonely" has a colder chill than "alone".

Years later, when word reached me that Mr. Hazlewood had died, I went back to the silent shop. On his workbench lay a note, left for me. It was short, reading: "The garden is yours now. Tend it well."

I finally understood. He was not just tending words; he was tending minds. He knew that a well-chosen word, planted in a moment of understanding, could bloom for a lifetime, its meaning ripening long after the gardener was gone.

Garbage Disposers (处理器)

John W. Hammes, an architect from Wisconsin, created the InSinkErator in 1935. Hammes got the idea after watching his wife spend time wrapping food in newspaper and throwing it out. The InSinkErator is a device, put under a kitchen sink between the sink's drain (排水管)and the trap. The disposal unit tears food waste into pieces small enough—generally less than 2 mm in diameter(直径) —to pass through the drains.

Surgical Gloves

William Stewart Halsted, M. D. (1852-1922)was a well-known US surgeon who is often called the "Father of Modern Surgery". Known for his strict insistence to sterile(无菌的) working conditions, Halsted invented rubber gloves that allowed his colleagues to lessen the transfer of germs(细菌)during their work. Yet the initial reason why he created them is more romantic than you would think. Knowing Caroline, a nurse, suffered from a skin diseuse during her work, Halsted invented the gloves especially for her and gave them to her as a gift after their marriage.

Band-Aids

When Josephine Knight Dickson from New Jersey kept cutting herself while cooking for her family in the 1920s, her husband, Earle Dickson, stepped in. Dickson, a cotton buyer for Johnson &Johnson, according to the company's website, decided to invent a temporary adhesive (有黏性的) bandage for his wife. His creation became the Band-Aid we all know and use today.

Magnetic (有磁性的)Shirt Buttons

Maura Horton's husband, Don, was a football coach who had Parkinson's disease. One day, after Don struggled to button his shirt before a game, Horton decided there needed to be a better clothing option for people suffering from a disability. So, Horton designed a shirt with magnetic buttons in 2012. These buttons will finally allow everyone to dress and undress themselves efficiently.
