1 . If you’ve scrolled through your Facebook feed recently, you may have noticed something surprising: lots and lots of short videos.
What makes this “Reels” feature strange is that it is hugely addictive, which I know quite well from my own personal experience. Last Friday, I took a break and hit on one short clip of someone making dinner and, well, the next time I looked up it was 20 minutes later and the blank document on my computer monitor was confirming to me that my work was still not done.
However, as silly as it seems, Reels-is actually super important, and is at the centre of a major battle between the world’s largest tech firms. The format (格式) was first pioneered by TikTok-the Chinese-owned video app that has taken the world by storm since it launched in 2016. Today, TikTok has around 23 million UK users every month-including basically every person you know under the age of 25. And that fact has made Facebook and its parent company, Meta, very nervous indeed. As TikTok has continued to boom, Facebook has actually fallen in popularity among “Gen Z”. The reason Tik Tok has proven such a powerful challenger to Facebook’s social media dominance is almost entirely down to these sorts of short-form videos.
The format is almost perfectly optimised to be as addictive as possible: Tik Tok’s app shows you a short-form video, and if you don’t like it, you can simply swipe it away and another one will start playing instantly. And because it is portrait, not landscape, videos look “right” when viewed on your phone. What’s also smart is that TikTok’s algorithm (算法) picks videos for you based on what you actually watch, and not what you say you want.
Facebook isn’t the only app trying to do what TikTok does so well. Instagram, which is owned by Facebook’s parent company Meta, has integrated Reels even more aggressively into its app. And even Google is nervous, launching its own TikTok-style video section of YouTube(which it owns)a couple of years ago. As things stand, though TikTok currently maintains a healthy lead in the category, both YouTube and Facebook have deep pockets-so expect to see even more Reels and Shorts popping up in your feed as this intense battle continues to rage. You won’t be able to take your eyes off them.

2 . Obese people experience discrimination (歧视) in many parts of their lives, and the workplace is no exception. Studies have long shown that obese workers, defined as those with a body-mass index (BMI) of 30 or more, earn significantly less than their slimmer co-workers.
Yet the costs of weight discrimination may be even greater than previously thought. “The overwhelming evidence,” wrote the Institute for employment Studies, “is that it is only women living with obesity who experience the obesity wage penalty (薪资损失).” They were expressing a view that is widely aired in academic papers. To test it, The Economist has analyzed data concerning 23,000 workers from the American Time Use Survey, conducted by the Bureau of Labour Statistics. Our number-processing suggests that, in fact, being obese hurts the earnings of both women and men.
The data we analyzed cover men and women aged between 25 and 54 and in full-time employment. At a general level, it is true that men’s BMIs are unrelated to their wages. But that changes for men with university degrees. For them, obesity is associated with a wage penalty of nearly 8%, even after accounting for the separate effects of age, race, graduate education and marital status.
The conclusion — that well-educated workers in particular are penalized for their weight — holds for both sexes. Moreover, the higher your level of education, the greater the penalty. We found that obese men with a Bachelor’s degree (学士学位) earn 5% less than their thinner colleagues, while those with a Master’s degree earn 14% less. Obese women, it is true, still have it worse: for them, the equivalent figures are 12% and 19%, respectively (分别地).
Your line of work makes a difference, too. When we dealt with the numbers for individual occupations and industries, we found the greatest differences in high-skilled jobs. Obese workers in health care, for example, make 11% less than their slimmer colleagues; those in management roles make roughly 9% less, on average. In sectors such as construction and agriculture, meanwhile, obesity is actually associated with higher wages.
These results suggest that the total costs of wage discrimination borne by overweight workers in America are greater than expected. Now, it’s time for our governments to take it seriously.

3 . There are well-documented mental health benefits to pet ownership, as much research has shown. Indeed, we know there are some physical benefits as well, as dog owners tend to have more active lifestyles. Yet when it comes to conditions like allergies (过敏), we tend to think of pet ownership as exacerbating, not alleviating them.
Hence, a recent study published in the journal PLOS One might come as a surprise. The study, published Wednesday, found that children raised with cats and dogs early in life had a 13 to 16 % lower risk of developing all food allergies than those who did not own pets.
The researchers engaged in a detailed survey, studying 65,000 children. They found that children who were exposed to dogs either during fetal (胎儿) development, or up to the age of 3 years old were less likely to have nut, milk and egg allergies.
This wasn’t true for other pets that weren’t cats and dogs. Indeed, the same research found that children exposed to hamsters during this same period had an increased risk of nut allergies. Yet children who were exposed to cats during their early years were likewise less likely to develop specific allergies — namely, allergies to wheat, soybean and egg.
While the study is not the final word on the issue — the researchers note “further studies using oral food challenges are required to more accurately assess the incident of food allergies” — it reinforces preexisting research on the seemingly funny ways that cats influence human development.
In addition to adding to the growing body of scientific literature about pets and human health, the PLOS One also reinforces earlier research about the role of the environment in developing allergies. The research repeatedly found that exposure to farmyard dirt, dust and the various fine hairs that fly off animals helps children in their breathing system development.

4 . Does a happy person live longer? Many studies have convinced us that happiness brings good health, which has resulted in an increasing demand for speakers and products encouraging positive thinking. However, being happy does not promise that one is going to be healthy. There are other factors that influence one’s health and long life such as a person’s genes or even a person’s socio-economic condition.
Some research even suggests that positive thinking can be dangerous. Positive thinking, when taken to the extreme, can cause a person to be separated from reality. For example, a person who thinks that staying happy and positive can help him recover from an illness like cancer but later fails to recover from it, may blame himself for not being happy. In this case, positive thinking may potentially make the victim disregard other factors. Sometimes the pursuit of happiness is even associated with serious mental health problems such as depression.
All types of happiness are not good for us either. For example, pride, a pleasant feeling, can sometimes rob us of the ability to empathize with others or understand another’s viewpoint. This anti-social behavior can cause people around us to turn away from us, and this could, in turn, make us feel lonely and do harm to our mental and even physical health.
Moreover, unpleasant feelings can be beneficial to a person’s well-being. Researchers believe that unpleasant feelings can help us make sense of our challenges and experiences in a way that supports psychological well-being. For example, if I have behaved badly towards my good friend, the feelings of guilt and sadness might motivate me to apologize and ask for forgiveness. The rebuilding of a broken relationship can be a lift to one’s mental well-being.
In trying to experience happiness, we should remember that seeking for happiness as an end in itself can be self-defeating, and does not necessarily lead to better health. After all, one will surely experience setbacks and conflicts in life. Instead, learning to cope with negative emotions with a realistic positive attitude is key to a person’s good health.

5 . The Greek philosopher Heraclitus once said that you can’t step into the same river twice, for you aren’t the same person at each visit and the water is ever flowing. It is a powerful way to show the reality that everything is always changing. Yet so many people have unpleasant relationships with change. We resist it or attempt to control it, the result of which is almost always some combination of stress, anxiety, and burnout. It doesn’t have to be that way.
No doubt, change can, and often does, hurt; but with the right mindset, it can also be a force for growth. A concept called allostasis can help. Developed in the late 1980s by neuroscientist Peter Sterling and biologist Joseph Eyer, allostasis is based on the idea that rather than being rigid, our healthy baseline is a moving target. Allostasis is defined as “stability through change”—the way to stay stable through the process of change is by changing.
From neuroscience to pain science and psychology, allostasis has become the dominant model for understanding change in the scientific community. The brain is at its best when it is constantly rewiring itself and making new connections. Overcoming pain is not about resistance or trying to get back to where you were but about balancing acceptance with problem-solving and moving forward to normal.
The time to start practicing is now. Over the past few years, the river of change has been flowing, and it shows no signs of letting up. Our ability to work with these changes is directly related to our life satisfaction. Given all this, simply creating a stable expectancy around change goes a long way. So does realizing that the allostasis mindset doesn’t ask us to do nothing. Rather, it asks us to partake in change by focusing on what we can control and trying to let go of what we can’t. When I catch myself resisting change, in my head I say the following: “This is what is happening right now. I’m doing the best that I can. What, if any, skillful actions can I take?” Do this repeatedly and finally you start to get better at it.
To thrive in our lifetime — and not just survive —we need to transform our relationship with change, leaving behind rigidity and resistance. We are always shaping and being shaped by change, often at the very same time.

| C．To overlook it. | D．To adapt to it. |
| A．One size fits all. | B．Time works great changes. |
| C．Respond to change by changing. | D．It’s never too late to change. |
| A．Stopping. | B．Dashing down. |
| C．Going up. | D．Widening. |
| A．Repetition makes up for rigidity. | B．It matters to focus on what we can’t. |
| C．Changes promote life satisfaction. | D．It makes sense to embrace changes. |
6 . In the Pixar movie Up, a fun cartoon dog called Dug wears a magical collar which can detect and translate his barks and cries into fluent human speech. Humans have always been fascinated by the potential to communicate with the animals. This week, an article in the New York Times documented major efforts from a group of researchers using machine-learning algorithms (算法) to analyze the different calls of whales, chickens, bats, cats, and more.
There are several ways to train AI systems now. Typically, Al systems learn through training with labeled data of human language which can be well supplied by the Internet. But analyzing animal language is different. Scientists have to instruct software programs on what to look for, and how to organize the data. This process requires matching gained vocal (发声的) recordings with the visual social behaviors of animals. A group studying Egyptian fruit bats, for example, also used video cameras to record the bats themselves to provide context for the calls.
Many critics of this approach point out two weaknesses of current AI language models: being unable to truly understand the relationships between words and the objects in the real world, and scientists’ little understanding of animal societies. Al language models for humans rely on a computer mapping out the relationship between words and the contexts they could appear in. But these models have their own weak points, and can sometimes be a black box—researchers know what goes in and comes out, but don’t quite understand how the algorithm is arriving at the conclusion.
Another factor that researchers should take into account is that animal communications might not work at all like human communications. There might be unique elements to animal language due to physiological and behavioral differences.
Making a Translator for animals has been a popular project that’s been in the works for the last decade. Although some software has shown some success in identifying the basic vocabulary of certain animals, it’s still a far cry from understanding the complex animal languages.

7 . Over 7,000 species around the world are considered endangered. That number doesn’t even include the plants, animals, and other lifeforms that are listed by some scientists as vulnerable, critically endangered, or extinct in the wild.
The International Union for Conservation of Nature (IUCN) maintains the most-comprehensive list of endangered species around the world. The Red List of Threatened Species, as it’s called, judges each species on five different standards for an in-depth scientific approach. According to the IUCN, an endangered species is one that meets any one of the following criteria (标准): a 50%-70% population decrease over 10 years, a total geographic area less than 5,000 square kilometers, a population size less than 2,500 adults, a restricted population of 250 adults, or a statistical prediction that it will go extinct within the next 20 years.
Though the IUCN’s Red List covers a wide range of what qualifies as an endangered species, it doesn’t quite say how a species reaches those low points. Prepare to feel guilty: the most common factor when it comes to species decline is human intervention. Loss of habitat, the introduction of a foreign species into the environment, hunting, pollution, disease, and loss of genetic variation (基因变异) are all causes of species decline and most often are a result of human activities. Take the bald eagle for example: the rise in human population and urban development of North America limited the animal’s habitat; an increase in hunting the eagles for sport lowered their population size; and the use of the pesticide DDT on farms harmed the animal’s reproductive capabilities.
But even though humans are the number one cause of species decline, classifying species as endangered encourages action to reverse the effects of human intervention. Conservation efforts by the US Fish and Wildlife Service criminalized (使非法) the hunting of bald eagles and the use of the pesticide DDT in the mid- to late 20th century. The effect was positive, as bald eagles have been on the rise and were taken off the endangered species list in 1995.

9 . Liu Jichen, 23, a student from Tsinghua University, has developed a WeChat mini-program called “Clear Your Plate”. After a meal, users can open the mini-program and take a picture of their empty plates. Once the image is recognized by the AI(Artificial Intelligence), students can collect points and use them to buy gifts or purchase charity meals to children in impoverished(贫困的) rural areas.
Liu and his team, together with other organizations, launched the “Clear Your Plate” campaign in November for the third year. It has swept over 1,017 universities across the country. The one-month campaign attracted almost 1.6 million participants and collectively reduced food waste by 862 tons and carbon emissions(碳排放) by 3,337 tons.
“Technological innovation is a good way to reduce food waste,” Liu thought. He organized a team of 20 members to work on the project at the end of 2017. To solve the AI’s problem of identifying photos of empty plates, the team spent half a year collecting over 100,000 samples in canteens and restaurants. In 2018, the mini-program was officially put into operation on Oct 16, World Food Day. They then launched a campaign later that year.
“There were so many unknowns in research and development. For our team members, the biggest challenge was whether we were confident enough to complete it,” Liu said. They not only achieved their goal, but now, the mini-program has more than 5 million registered users, according to Liu. “We hope our efforts can start a new trend among the younger generation by encouraging them to cherish(珍惜) their food and develop the habit of thrift(节约),” Liu added.
