1 . Goldfish may seem like simple creatures swimming in a glass tank, but they possess a rather complicated navigation system, as discovered by researchers at the University of Oxford Led by Dr. Adelaide Sibeaux, the study aims to shed light on our understanding of how fish, and potentially humans, estimate distances using what could be described as an internal GPS.
Writing in the journal Proceedings of the Royal Society B, Sibeaux and colleagues report how they created a tank in their experiment with 2cm-wide black and white vertical stripes (条纹) on the walls, connected by similar stripes across the floor. The team trained nine goldfish to swim a set distance of 70cm and then return to their starting point when waved at. The experiment aimed to investigate how the fish would estimate this distance without any gestures, under different patterns.
Over multiple trials, the goldfish averaged a swim distance of 74cm, give or take 17cm, when presented with the vertical 2cm-wide stripes. However, when the stripe pattern was altered to either narrower vertical stripes, checked patterns, or horizontal stripes, the fish’s behavior changed significantly. Narrower vertical stripes led them to overestimating the distance by 36%, while horizontal stripes resulted in highly inconsistent estimations.
According to the researchers, the goldfish appeared to be using an “optic (光学的) flow mechanism” based on the visual density of their environment. They kept track of how frequently the vertical pattern switched between black and white to estimate how far they had traveled. The study suggests that different optic flow mechanisms are used by mammals, including humans, based on angular (有角度的) motion of visual features. The study implies that the use of visually based distance information could have emerged early in the evolutionary timeline.
“This study is novel because, despite knowing that fish respond to geometric information regarding direction and distance, we don’t know how they estimate distances,” Professor Colin Lever, although not involved in the study, said, “it’s exciting to explore fish spatial mapping because fish navigation evolved earlier and better than most mammals.”

2 . Personal growth doesn’t necessarily only happen when the conditions are perfect. Seeds tend to develop only when conditions are right. A seed will remain dormant (休眠) until moisture (湿度) and temperature are favorable for growth. Unfortunately, as humans, we don’t always have the luxury of growing when conditions are just right. Sometimes you must cultivate (促进) personal growth and flower where you’re planted, often in spite of external (外部的) circumstances.
For much of my life, I let external circumstances control my happiness. If things weren’t going well, then I wasn’t well. I told myself that I would be happier if conditions were right. With this mindset, I gave myself permission to stay emotionally dormant. I was waiting for things around me to change before I would do the work to become a better version of myself. In other words, I made my personal growth conditional on external circumstances.
The problem with waiting for change outside of yourself is that you might have to wait a very long time, maybe even forever. And if you stay dormant while waiting, you aren’t growing. You’re simply stuck in place. You certainly aren’t becoming the better version of yourself that you want to be.
If you want to engage in personal growth, like planting seeds, you have to do some work to make it happen. You can’t wait around for everything to fall into place. Start with pulling up your emotional weeds. Examine yourself and remove the pessimistic thoughts and behaviors that are holding you back. Then, work on the foundation that you have. Practice positive life habits that build your self-respect and happiness.
Personal growth is something you can fight for. It may not come naturally, but when you develop this mindset, you will flower no matter where you’re planted.

4 . Hangzhou, China—a stunning opening ceremony laden with Hangzhou characteristics amazed the world on Saturday, as President Xi Jinping declared the 19th Asian Games open.
With the city’s profound history, culture and its modern image presented in an eye-catching and high-tech fashion, the opening show helped to express the host’s warm hospitality and its wish to unite the world through sports. Following an opening performance depicting the autumn equinox (秋分), one of China’s 24 solar terms that celebrates the harvest season, over 50,000 spectators burst into cheers as Xi announced the opening of the Hangzhou Games, making the Zhejiang provincial capital the third Chinese city to host the continental sporting gala, following Beijing in 1990 and Guangzhou in 2010.
Wang Hao, president of the 19th Asian Games Hangzhou Organizing Committee, said Hangzhou is honored to play host to such a grand event, which started on September 23rd. Raja Randhir Singh, the acting president of the Olympic Council of Asia, showed appreciation for the Chinese host’s meticulous (细心的) organization in his speech. “You have done a fantastic job in preparing for the Asian Games. The one-year postponement due to the pandemic was unprecedented in OCA history, but your diligence and determination will bear fruit over the next 16 days and you will be rewarded with the most magnificent and successful Asian Games ever,” said Singh.
Supported by new technologies, the Hangzhou ceremony boasted many historic firsts. For the first time in China, organizers switched from a traditional fireworks show to a virtual display, projected (放映) onto a giant curtain screen the size of nine IMAX screens.
To adhere to the principle of delivering the greenest possible Games, zero-emission methanol was used to fuel all of the torches and the main cauldron. For the finale, hundreds of millions of virtual sparks, each representing a participant of the online torch relay, formed the shape of a human torchbearer, who ran into the stadium to light the main cauldron together with the physical relay’s final bearer — Zhejiang native and Olympic champion swimmer, Wang Shun.

5 . 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.

6 . Whenever you read text, your brain processes the visual stimuli (刺激物) to create meaning and understand the content. Chances are, you don’t pay much attention to the way the information is presented- particularly the font (字体) choice. That’s because your main target is reading comprehension, not aesthetics.
Although typography(排印) is missed by most of us, it’s essential in making texts legible, readable and appealing for audiences. Beyond the visual aspect, research shows that fonts play a significant role in the mental processes of understanding that happen while we read. A font’s impact on the way you learn and memorize information might be hard to notice consciously, but your brain is certainly tuned in. Perhaps surprisingly, hard-to-read fonts such as Bodoni, Comic Sans, or Monotype Corsiva are better for memorizing information than fonts like Arial or Times New Roman, according to some studies.
“Difficulty can function as an alarm signal, giving the reader a sense that the task is challenging and will require mental effort,” says Daniel Oppenheimer, a professor of psychology at Carnegie Mellon University and one of a 2010 study authors, “Additionally, slowing down the reading speed to deal with the disfluency may increase the probability of spotting errors in a text.”
Font characteristics such as style, size and color play a role in information retention memory or recall as well, says Stephen Banham, a typography lecturer at RMIT University in Melbourne, Australia. Experiments have proved a U-shape relationship between font size and memory: Large-font items may predict higher recall regardless of style, but very small font sizes can also introduce a desirable difficulty.
A document’s specific method of formatting information also makes an impact. Using font styles like bold or italics to indicate significance can also improve memory. That’s because people are better able to remember information they consider important, says Oppenheimer. Researchers found that bolded text has a higher recall than text in italic or regular styles, regardless of the font size. However, if an entire document is bolded, the emphasis is lost, and readers can no longer spot vital passages.

7 . Worth nearly $1trn, Facebook is the world’s sixth-most-valuable company. Its revenues have grown by 56% in the past year, and its share price by more than a quarter. Nearly 3bn people use its products every month. Why did such a successful company change its name as Meta?
The likely official reason for the rebranding is that the firm has outgrown the social network that Mark Zuckerberg started 17 years ago in a Harvard dorm. Today it includes other social apps (Instagram, WhatsApp, Messenger) and video hardware (Oculus, Portal). It has launched a digital wallet (Novi) and may yet offer a currency (Diem). Mr Zuckerberg expects people eventually to associate his firm more with the “metaverse”(元宇宙), a virtual space for work, play and more, than with social media.
Facebook wouldn’t be the first tech giant to do so. In 2015 Google set up Alphabet, a holding company for the search engine and its many side projects. Under this model, Facebook would become just another app within a wider family, though by far it has been the biggest earner.
There is another possible motive for a makeover. For all its financial success, the Facebook brand has become tarnished. The social network is blamed for fueling everything from teenage anorexia(厌食症) to uprising at the US Capitol. Public trust in it is lower than in most tech giants, and falling. Although two years ago the firm started branding its apps as being “from Facebook”, its new smart glasses, which can record video and take phone calls, feature only the logo of its partner, Ray-Ban. A former employee revealed that Facebook was trying to cover up a drop in young American users.
Mr Zuckerberg himself has been a reason for much of the criticism of Facebook, and of bossy tech firms more generally. As the all-powerful founder, he has a higher profile than his opposite numbers at TikTok, YouTube and other social networks. Normally, a brand facing a reputational crisis might dump its unpopular CEO. But Mr Zuckerberg’s position is immovable, which may explain why he would want to dump the brand instead.

8 . Search engines have changed the way we use the Internet, putting vast sources of information just a few clicks away. But Harvard professor of psychology Line Daniel Wegner’s recent research proves that websites and the Internet are changing much more than technology itself. They are changing the way our memories function. Wegner’s latest study shows that when people have access to search engines, they remember fewer facts and less information because they know they can rely on “search” as a readily available shortcut.
Wegner believes the new findings show that the Internet has become part of a transactive memory source, a method by which our brains divide information, which means you don’t have to remember everything in the world yourself. You just have to remember who knows it. Now computers and technology are becoming virtual extensions of our memory.
Wegner conducted several experiments to demonstrate the phenomenon, using various forms of memory recall to test reliance on computers. In one experiment, participants demonstrated that they were more likely to think of computer terms like “Yahoo” or “Google” after being asked a set of difficult trivia questions. In another experiment, participants typed some statements into a computer and they were told the statements would be saved in specific folders. Next, they were asked to recall the statements. Finally, they were given cues to the wording and asked to name the folders where the statements were stored. The participants proved better able to recall the folder locations than the statements themselves.
Wegner admits that questions remain about whether dependence on computers will affect memories negatively: “Nobody knows now what the effects of these tools are on logical thinking.” Students who have trouble remembering distinct facts, for example, may struggle to employ those facts in critical thinking. But he believes that the situation overall is beneficial, comparing dependence on computers to dependence on a mechanical hand or other prosthetic device.
And even though we may not be using our memories to recall distinct facts, we are still using them to consider where the facts are located and how to access them. “We still have to remember things,” Wegner explains. “We’re just remembering a different range of things.” He believes his study will lead to further research into understanding computer dependence, and looks forward to tracing the extent of human interdependence with the computer world — pinpointing the “movable dividing line between us and our computers in cyber networks.”

10 . “Meet me in the conference room with the contracts and a cup of coffee,” my boss barked at me. “Ten minutes.”
I didn’t respond. I stood still as if my shoes had been glued to the floor. I had no intention of taking a cup of anything to anyone, supervisor or not.
I had seen with my own eyes what such behavior did to a woman. It happened to Mrs. Wilson next door. Old Mr. Wilson wouldn’t put in his own false teeth without his wife’s assistance, let alone make himself lunch. It was a miserable union. I vowed by age eight that I would never live like her. I adopted the motto: Don’t help those who won’t help themselves.
I rushed to the file room and pulled my phone. I explained to my father what had happened and asked his advice on what to do, only to be asked back. He must have forgotten the unwritten rule between us about not answering a question with a question. Fortunately, I came up with an idea that would have the best of both worlds.
I took up the files and headed for the coffee pot. I took two cups and made two cups of coffee. Then I walked into the boss’ office with a cup of coffee in each hand. I handed my boss a cup of coffee and drank at the same time as him.
“Let’s take a break,” partway through the meeting, my boss stood, saying, “I need more coffee.” I picked up my empty cup. “I do, too,” I said, and handed it to him across the table. “Thanks,” I added, looking at him expectantly. The boss was staggered for a moment, and then took the cup from me.
When I finally left my boss’ office, I hid in the bathroom and called my dad. My father’s laughter on the phone made me feel even prouder.
