3 . Artificial intelligence (AI) has been increasingly good at fooling people. A series of photos showing former US president Donald Trump being aggressively arrested by police have caught people’s attention. They were fake but very convincing.

Created by the AI program Midjourney, the photos were highly realistic, from the characters’ movements to the surroundings. However, many details can give away the fact that they are made by AI. The Washington Post’s technology writer Shira Ovide shared her tips. The main idea is to spot the problems-anything that would look strange in a photo.

AI software has a history of generating human hands incorrectly. It sometimes can create hands with more than five fingers. This is because AI isn’t sure what a “hand” exactly is, according to Popular Science. The data AI uses to learn often show hands and fingers in various gestures, which can be very confusing for AI.

AI-generated images also usually contain details that are against reality. To spot this, focus on items like accessories. For example, people in an image may be missing earrings or one part of their sunglasses. If there’s text in an image, such as a newspaper or poster, it’s usually garbled (篡改), even though the text may look realistic from a distance.

Another thing AI is terrible at handling is the background. If there’s a crowd in the image, people’s faces in the background are usually blurry — or they don’t have faces at all!

The development of AI-generated art also raises alarm bells about how these fake images could be used to spread misinformation. “I think misinformation is going to hit an all-time high,” Jamie Cohen, a digital culture and AI expert in the US, told New York Post. Generating an AI artwork is to “create reality”, Cohen argued, adding that, being able to tell whether the work is real or not requires high media literacy (素养) skills. “The world may not be ready for how realistic the images have become,” Shane Kittelson, a US researcher, told The Washington Post.

5 . Reading can be a social activity. Think of the people who belong to book groups. They choose books to read and then meet to discuss them. Now, the website Book Crossing.com turns the page on the traditional idea of a book group.

Members go on the site and register (登记) the books they own and would like to share. Book Crossing provides an identification number (识别码) to stick inside the book. Then the person leaves it in a public place, hoping that the book will have an adventure, traveling far and wide with each new reader who finds it.

Bruce Pederson, the managing director of Book Crossing, says, “The two things that change your life are the people you meet and books you read. Book Crossing combines both.”

Members leave books on park benches and buses, in train stations and coffee shops. Whoever finds their book will go to the site and record where they found it.

People who find a book can also leave a journal entry describing what they thought of it. E— mails are then sent to the BookCrossers to keep them updated about where their books have been found. Bruce Pederson says the idea is for people not to be selfish by keeping a book to gather dust on a shelf at home.

Book Crossing is part of a trend (趋势) among people who want to get back to the “real” and not the virtual (虚拟).The site now has more than one million members in more than one hundred thirty—five countries.

7 . Peter, 60, loved his job as a bus driver. He had been one almost all his life, loving the little children who rode his bus daily. It made him feel much younger. His record was clean, without one accident, which made him a trustworthy driver.

However, Mr. Clark, Peter’s boss, was worried and thought that it was time for him to retire (退休). “You don’t have a choice here, Peter.” he said seriously. “We don’t want to invite any risk to the children.”

“But I have a perfect record,” reasoned Peter. “You know, for an elderly man like me, my job is the only thing that keeps me alive. I want to keep my job.”

“Would you take responsibility if something bad happened to those children?” Mr. Clark said.

Peter thought it over, and very reluctantly, he gave in to Mr. Clark’s request. Peter decided to retire a week later.

The day before his last day, Peter was dropping of the kids at his first stop when he looked out of the window and saw a lady who had passed out. He asked the kids not to leave the bus and got down to help the woman.

Just when he finished, he heard cries behind him. The children were looking out of the window and shouting. “Fire! Fire! Help!” “How could that have happened?” Peter was shaking in fear. With shaking hands, Peter dialed 911 and rushed to help the children. Covering himself with his jacket, Peter rushed into the burning car and took the children out one by one. Thankfully, the firefighters arrived soon and helped Peter, saving all students.

The next day, Peter found the whole school standing in front of his home. When Peter got close to them, Mr. Clark started clapping and everyone joined him. “You are a hero, Peter! You saved the lives of those young children.” he said. “You are the best driver. We hope you can keep the job!”

10 . It is often said the laughter is the best medicine. But researchers at the University of Oxford think the ability to belly laughs (捧腹大笑) was unique to early humans. This, they believe, made our ancestors (祖先) able to form much larger groups.

The researchers first tested the pain thresholds (临界值) of some volunteers. They divided them into two groups. One group was shown15 minutes of comedy videos, while the other was shown boring programs.

Through this experiment, the researchers found that those who had recently experienced belly laughs were able to withstand (忍受) up to 10% more pain than they had done before watching the videos. To their surprise, the scientists also found that the other group was less able to withstand pain after watching 15 minutes of the “boring” programs.

Professor Robin Dunbar of Oxford University, who led the research, believed that belly laughs release chemicals called endorphins (安多芬) into the body which make us feel less painful.

However, not all comedy programs had such effects, according to Prof Dunbar. For example, though clever stand-up comedy was found to be enjoyable, it had no effect on raising pain thresholds. “Things that worked very well were interesting comedies such as Mr. Bean. Situation comedies such as Friends also seemed to be particularly successful,” he added.

In order to measure (测量) endorphin levels, the researchers put a bag of ice on the volunteers’ arms to see how long they could withstand them. They found that the greater the increase in pain thresholds, the greater the amount of endorphins produced.

The purpose of Prof Dunbar’s study was not to develop a new treatment. Instead, it was to study the role of laughter in the forming of human societies two million years ago.

“The next stage will be to see whether laughing really allows people to keep together and work as a group better and be more friendly towards each other. If that is the case, then it may explain why some two million years ago, the first humans were able to form large communities of up to 100,” Dunbar added.
