1 . Consider the following statement: “My husband bought me a pink Lamborghini...” The correct way to finish the sentence, according to some, is not showing appreciation or acting excited, but to complain about the pricy gift. If you say, “The color is so ugly, men have such bad taste!” Congratulations, you have mastered the “Versailles (凡尔赛) literature.”

The term has nothing to do with the French palace nor with literature. It came from the Japanese manga series “The Rose of Versailles” and was coined by a Chinese influencer earlier this year. This new kind of bragging (吹嘘) is called humblebragging, the psychology behind which is to be recognized for one's successes and be liked by others at the same time. “The humblebragger recognizes that it's hard to be liked and be a showoff at the same time,” said psychologist Dr. Susan KraussWhitbourne at the University of Massachusetts Amherst.

In an article titled “Why people hate humblebragging” published in Psychology Today, Whitbourne noted that the humblebrag is a “strategy in pursuit of respect” because it draws attention to one's accomplishments, but in a roundabout (迂回的) fashion.

However, studies on social media users show that humblebragging, as a self-promotion strategy does not work. In the essay, “Humblebragging: A distinct-and ineffective-self-presentation strategy,” researcher Ovul Sezer concluded from his research that humblebraggers are perceived more negatively than straight braggers due to the former's insincerity. “The critical factor telling these strategies was sincerity. People don't like braggers, but they at least see them as more sincere than humblebraggers.”

“So, next time if you hear ‘My husband bought me a pink Lamborghini. The color is so ugly, men have such bad taste!’. Just pretend you don’t get whatever it is they try to show off.” a Zhihu user advised others on how to respond to a “pretentious narcissist”, “Respond with genuine sympathy for their complaint.”

2 . More than one-third of the world’s food is wasted or thrown away, most of which ends up in landfills, producing very large amounts of planet-warming greenhouse gases. Now, many studies show that it is becoming harder to grow enough food to feed an increasing population due to climate change and soil degradation.

But one of the most promising and simplest solutions lies in the problem itself: this wasted food — if composted (堆肥) — could slow climate change and improve soil quality. Higher-quality soil also continues to absorb more carbon from the atmosphere, helping to improve plants and contributing further to fighting climate change. Returning one ton of organic matter to each hectare of soil would increase the production of cereal crops each year in Africa, Asia and South America by millions of tons.

While it is true that people can compost in their yards, community gardens, or even on their kitchen counters, larger-scale efforts, including infrastructure (基础设施) and incentives (激励) for consumers, would take it to the next level. Imagine if consumers could just leave unwanted food in a roadside bin for pickup, or drop it off at a local store, earning a few cents a bucket, just like what has been offered for recycling bottles or newspapers.

Moreover, in the case of composting, the payment incentive system would be sustainable because the end-product of compost can be sold to farmers, making it an economically workable model, something that is often lacking in recycling, especially for certain materials, like many types of plastics.

Eventually, more widespread composting of food would pave the way for solutions to additional waste challenges, such as the disposal of packaging and clothing. This will have other positive effects as well; if more consumers compost, companies will be more inspired to make and use compostable packaging, clothing, and other products. While more compostable items are starting to emerge today, additional composting will further drive demand and innovation, and offer a game-changing solution for the planet.

9 . The history of the school bus can date back to 1886 when the Wayne Works company made horse-drawn carriages (四轮马车) known as “ school wagons” or “kid hacks” in Indiana.     1    

In the early 1900s, the car industry was beginning to develop fast.    2     The company managed to make its carriages powered by engines. But the design remained mostly the same as that of the previous ones, with students sitting along the walls of the bus while facing inside.

In 1927, a man built the first bus that primarily used steel. Before long, Wayne Works introduced the first all-steel school bus body with safety glass windows.     3     This led to a turning point in the history of the school bus in 1939, when a conference was organised at Manhattan College to develop school bus standards.

Many new national standards were created, determining everything from seating designs to the famous yellow color that school buses still sport today. The reason why the color was chosen was simple.     4    The color is especially easy to see in the early morning and evening light when school buses usually operate.

    5     For example, a variety of changes have been made to enable the school bus to not only be safer but also have better fuel (燃料) economy, be easier to drive, etc. The most creative approach among all of these is probably a kind of stop signal arm that warns traffic of a stop in progress, which states began to require in the early 1950s.

10 . Researchers have tapped the brainwaves of a paralyzed (瘫痪的) man unable to speak and turned what he intended to say into sentences.

The device, created by a team at the University of California, San Francisco, analyses brainwaves to decode (解读) what a person is trying to say and then displays the text on a computer screen. The additional research will take years but the results of the current studies mark an important step toward one day bringing back more natural communication for people who can’t speak because of injuries or illnesses.

The person volunteering to test the device was a man in his late 30s who 15 years ago suffered a brainstem stroke that caused widespread paralysis and robbed him of speech. The researchers placed electrodes (电极) on the surface of the man’s brain, over the area that controls speech. A computer analysed the patterns when he attempted to say common words such as “water” or “good”, eventually becoming able to discern 50 words that could produce more than 1,000 sentences.

Started with such questions as “How are you today?” or “Are you thirsty?”, the device eventually enabled the man to answer “I am very good” or “No, I am not thirsty” - not voicing the words but translating them into text. It takes about three to four seconds for the word to appear on the screen. That’s not nearly as fast as speaking but quicker than tapping out a response.

Harvard neurologists called the work a “pioneering demonstration”. They suggested improvements but said if the technology works out, it eventually could help people with injuries, strokes or illnesses like Lou Gehrig’s disease.

Next steps include ways to improve the device’s speed, accuracy and vocabulary size, and maybe one day it will allow a computer-produced voice rather than display text on a screen while testing a small group of volunteer patients.
