1 . Teachers worried about students turning in essays written by a popular artificial intelligence chatbot now have a new tool of their own.

Edward Tian, a computer science major at Princeton University, has built an App called GPTZero to detect whether a text is written by Chat GPT, which is a popular chatbot that has caused fears over its possibility for immoral uses in American academic circles. His motivation to create the computer program was to fight what he sees as an increase in AI plagiarism (剽窃). Since the release of ChatGPT in 2022, there have been reports of students using the language model to pass off AI-written assignments as their own. Many teachers have reached out to him after he released GPTZero, telling him about the positive results they’ve seen from testing it.

To determine whether an essay is written by a computer program, GPTZero uses two indicators: “confusion” and “burstiness (突发性)”. The first indicator measures the complexity of text; if GPTZero is confused by the text, then it has a high complexity and it’s more likely to be human-written. However, if the text is more familiar to GPTZero — because it’s been trained on such data — then it will have low complexity and therefore is more likely to be AI-generated. Besides, the second indicator compares the variations of sentences. Humans tend to write with greater burstiness, for example, with some longer or complex sentences alongside shorter ones. AI sentences tend to be more uniform.

In a demonstration video, Tian compared the App’s analysis of a story in The New Yorker and a Linked In post written by ChatGPT. It successfully distinguished writing between human and AI. However, GPTZero isn’t foolproof, as some users have reported when putting it to the test. He said he’s still working to improve the model’s accuracy.

Tian is not opposed to the use of AI tools like ChatGPT. GPTZero is “not meant to be a tool to stop these technologies from being used,” he said. “But with any new technologies, we need to be able to adopt it responsibly and we need to have protections.”

3 . Situated along a river that winds through the mountains, surrounded by cedar (雪松) and bamboo forests, Nanmoku is about 70 miles northwest of the capital city. Once known for its silk, wood, and konjac root (魔芋根), Nanmoku is now Japan’s most aged village, with two-thirds of its residents over 65. Many buildings are abandoned and the population has dropped from 11,000 in 1955to about 1,500 today, according to town hall figures. At that rate, the village could be empty just over a decade.

Nanmoku is on the front lines of Japan’s rural depopulation, a trend seen in other Asian and European countries. However, some residents are working to change the trend by attracting young people. One such person is 24-year-old Satomi Oigawa, who moved to Nanmoku after graduating from college in Tokyo. She works for the village government, matching abandoned homes with potential new residents. Oigawa is learning about the village’s history as she integrates into the community. “Everything about this house is part of the village’s history,” she says.

Despite efforts to attract new residents, the village faces challenges. There are few jobs for young people, and the nearest hospital is an hour’s drive away. Some residents argue that instead of spending money to attract newcomers, the money should be spent on those already living in the village.

Mayor Saijo Hasegawa aims to keep the village’s population level in 15to 20 years’ time, hoping to maintain it at around 800 people. However, experts like Peter Matan le of the University of Sheffield say that while some villages may boom, they will still experience pushback against the overpowering trend. “Japan is currently losing 600,000 to 700,000 people annually, and that’s going to increase to more than a million by the 2030s,” Matan le says. “Under that situation, how do settlements maintain their populations, let alone increase them?”

4 . Economic growth is often considered as a sure way of increasing the well-being of people in low-income countries, and global surveys in recent decades have supported this strategy by showing people in high-income countries tend to report higher levels of life satisfaction than those in low-income countries. This strong connection might suggest that only in rich societies can people be happy. However, a recent study conducted by ICTA-UAB and McGill University in Canada suggests that there may be good reasons to question whether this link is universal.

While most global surveys gather thousands of responses from the citizens of industrial and urban societies, they tend to ignore people in simple-and-tiny societies on the fringe, where social group has a limited number of members and where the exchange of money plays a minimal role in everyday life with natives and local communities depending directly on nature.

The research, published in the scientific journal Proceedings of the National Academy of Sciences (PNAS), consisted of a survey of 2,966 people from local communities in 19 globally distributed sites. Only 64% of surveyed households had any cash income. The results show that “surprisingly, many populations with very low incomes report very high average levels of life satisfaction, with scores similar to those in wealthy countries,” says Eric Galbraith, researcher at ICTA-UAB and McGill University and lead author of the study.

The average life satisfaction score across the studied simple-and-tiny societies was 6.8 on a range of 0-10. Although not all societies reported high satisfaction levels, four of the sites reported average scores higher than 8, despite many of these societies having suffered histories of neglect and control. The results are consistent with the opinion that human societies can support very satisfactory lives for their members without necessarily requiring high degrees of material wealth.

“While the reasons behind these findings remain unclear, the study provides valuable insights into how diverse communities achieve satisfying lives. It offers hope that understanding these factors can help others improve their well-being while addressing sustainability concerns.” Galbraith concludes.

5 . Short-form videos now dominate our social media feeds, with TikTok, Facebook and Google all fighting for our attention—but there can be only one winner.

What makes the videos strange is that they make people wildly addicted. Hit on a video, and you’ll find yourself flipping through dozens of short clips. I know from personal experience what this feeling is like. I’ll take a break and hit on one short clip and, well, the next time I look up, it’s 20 minutes later and the blank document on my computer monitor is reminding me that my work still hasn’t been done. However, as silly as it seems, short-form videos are actually super important, and are at the centre of a major battle between the world’s largest tech firms.

The format was first pioneered by TikTok— the Chinese-owned video app that has taken the world by storm since its launch in 2016. As TikTok has continued to boom, Facebook has emaly fallen in popularity. The reason TikTok has proven such a powerful challenger to Facebook’s social media dominance is almost entirely down to these sorts of short-form videos.

So you can understand why Facebook and other firms like Google wanted a piece of the action. Facebook first launched Reels globally almost exactly a year ago to try and take a share at this market. Even Google was nervous. launching its own TikTok-style video section of YouTube. And behind the scenes. the company has strong-armed some of the biggest video makers on its platform to start making Shorts.

Why are all three companies fighting so intensely over this form of video? Ultimately it’s because in the end it is likely that there will only be one winner. Whichever company can grow is short-form video business. the fastest is likely to end up with a big slice of our screen time and all of the profits that come with it

As things stand, though TikTok currently maintains a healthy lead in the category. both Google and Facebook have deep pockets-so expect to see even more Reels and Shorts popping up in your feed as this intense fight proceeds.

6 . “Pop” stands for popular, and a pop singer has to work very hard to stay popular. He must either give the public what they want, or he must find a new way of singing that will attract their attention. Even when he has succeeded, and his records are sold everywhere, he cannot relax. Then he must work harder than ever to remain popular, because there are always younger singers trying to become famous and to steal some of the popularity.

The life of a successful pop singer isn’t easy at all. He can only relax when he is alone, because everything he does is watched and reported in the special newspaper written for the fans. The fans are the most important people in the world for the singer. They buy his records, they go to his concerts, and they make him rich and famous. But they can be very annoying, too. Sometimes their enthusiasm (热情) is so hysterical (歇斯底里的) that they do anything to get a souvenir (纪念品). They steal handkerchief, they tear off buttons, and they even cut off pieces of unfortunate singer’s hair. Many singers have been forced to hide, and some who have not been so lucky as to escape have been stripped (剥) practically naked by their fans. A pop singer has to spend a lot of money on clothes because he must always look smart, or at any rate, different. He must have a luxurious (豪华的) car. And most importantly, he must always keep smiling for the benefit of his public.

8 . You’ve probably followed a few cute dogs and cats on social media. However, are you aware that Ai-generated pets are also gaining popularity nowadays? They are just as adorable as real dogs and cats but also exhibit human-like characteristics.

Chai Dada, 21, runs an AI-generated dog account called “Shizhuangzhuangya” on Xiaohongshu and has already got more than 10,000 followers. Her AI-generated pet Zhuangzhuang is a fluffy Shiba Inu with a big belly who likes to eat and work out. “Zhuangzhuang is actually a reflection of me,” Chai said. “Its life and mood basically reflect my own.”

To personify the character more, the young content maker places Zhuangzhuang in various daily life scenarios. For instance, responding to the recent increase of “hui nan tian”— the super humid (潮湿的) weather in southern China in spring — Chai posted images of Zhuangzhuangmopping a wet floor, with the caption. “It’s wet everywhere at home”; vividly capturing the mood. In the comments section, many have expressed sympathy (同情), for the poor dog.

“Many scenes may seem ordinary, but when a very lifelike and adorable human-like pet appears in these familiar scenes, it looks interesting,” Chai said. Since Zhuangzhuang closely resembles a human in a dog’s body, many followers have come to believe in its real existence. This has provided Chai with opportunities to monetize by partnering with brands for product advertisements. Aiming to expand her reach, Chai expressed a desire to dive deeper into AI to bring her AI pet to life not just in pictures but also in videos.

She also observed that more and more people like her are becoming AI pet bloggers, which has intensified competition in this industry. To attract more fans, bloggers are constantly learning more AI skills and brainstorming to create more interesting storylines. “I want to develop Zhuangzhuang into an intellectual property and create related cultural and creative products such as dolls and stickers,” said Chai.

10 . The standard public health threats are all-too familiar: smoking, high blood pressure, cancer. But a new government advisory made headlines in 2023 by adding an unexpected major to that list. Loneliness, stated the report from Surgeon General Vivek Murthy, is a widely under recognized U.S. health crisis. In recent years, about 50 percent of Americans have experienced loneliness, which results in adverse effects. Lonely people, as Murthy’s report warns, run the same mortality (死亡) risk as people who smoke 15 cigarettes a day.

On its face, Murthy’s warning sounds awfully alarmist. It’s hard to understand how a lack of companionship could be as threatening as an addiction or global pandemic. But humans are so biologically wired to be social that isolation damages our systems. People who lack social support have a 29 percent higher risk of heart disease, a 32 percent higher risk of stroke, and a 26 to 29 percent higher risk of premature death, according to the report. What’s more, such health effects in isolated older adults have led to about $6.7 billion in Medicare spending each year.

Scientists now know that loneliness can cause lots of health problems. That may be because our ancestors thrived (繁荣) in supportive communities. “Our brains function more efficiently when we are with others.” Says Julianne Holt Lunstad, a professor of psychology and neuroscience at Brigham Young University.

Since loneliness can feel so much like personal failure, it’s easy to assume people should just try to handle it on their own. But in reality, many of the factors that promote social isolation are structural ones. “It could be workplace policies that don’t allow flexibility to support personal relationships.” Holt Lunstad says. “It might be busy or unsafe streets that are barriers to getting to know your neighbors.”
