1 . The maker of ChatGPT recently announced its next move into generative artificial intelligence. San Francisco-based OpenAI’s new text-to-video generator, called Sora, is a tool that instantly makes short videos based on written commands, called prompts.
Sora is not the first of its kind. Google, Meta and Runway ML are among the other companies to have developed similar technology. But the high quality of videos displayed by OpenAI — some released after CEO Sam Altman asked social media users to send in ideas for written prompts-surprised observers.
A photographer from New Hampshire posted one suggestion, or prompt, on X. The prompt gave details about a kind of food to be cooked, gnocchi (意大利团子), as well as the setting — an old Italian country kitchen. The prompt said: “An instructional cooking session for homemade gnocchi, hosted by a grandmother — a social media influencer, set in a rustic (土气的) Tuscan country kitchen.” Altman answered a short time later with a realistic video that showed what the prompt described.
The tool is not yet publicly available. OpenAI has given limited information about how it was built. The company also has not stated what imagery and video sources were used to train Sora. At the same time, the video results led to fears about the possible ethical and societal effects.
The New York Times and some writers have taken legal actions against OpenAI for its use of copyrighted works of writing to train ChatGPT. And OpenAI pays a fee to The Associated Press, the source of this report, to license its text news archive (档案) . OpenAI said in a blog post that it is communicating with artists, policymakers and others before releasing the new tool to the public.
The company added that it is working with “red teamers” — people who try to find problems and give helpful suggestions — to develop Sora. “We are working with red teamers-express in areas like misinformation, hateful content, and bias — who will be adversarially testing the model,” the company said. “We’re also building tools to help detect misleading content such as a detection classifier that can tell when a video was generated by Sora.”

2 . About 20 years ago, I was attending a law school while still doing my part-time job to provide my tuition. Despite that, my grades were still among the top ten percent of the class.

Later, I wrote a letter to the local newspaper detailing this story and explaining how paper grades were subjective. The letter was then published. Knowing this, the professor was awkward. Luckily, I didn’t mention his name. He emailed me and explained he’d made a mistake and confused my paper with another student’s.

5 . Biologists Slagsvold and Wiebe have spent years studying tits, flycatchers, and other birds that lay their eggs into holes in trees, walls and even human-made boxes. “Holes are rare, so there’s great competition,” Wiebe said. Birds will sometimes get into fights. Even after a bird gets a hole, it has to watch out: There’s always a chance that a passerby tries to possess it. Owners don’t have many options to wait for and stop thieves. Some police their nest’s entrance hole, but preparing for parenthood is hungry work, and eventually the birds have to leave to get food. So Slagsvold and Wiebe started to look for alternative home-defense systems the birds might be using.
They noticed feathers, usually helping animals keep warm, but that doesn’t seem to be how these particular birds are using them. Blue tits, for instance, get feathers on top of the nest, rather than putting them in. Some other birds dump feathers into holes before gathering other materials. “They’re white, and often noticeable,” Wiebe said, “as if the birds want to send a message.”
To find out, they built nest boxes — some feathery, some not — in Europe and America, and recorded how tits, flycatchers and swallows reacted. The birds entered feather-free boxes quickly. But they froze at the sight of white feathers, sometimes hesitating outside for an hour. Black feathers scared them less, perhaps because they were harder to see. The feathers didn’t stop the birds as most eventually went inside. But even a brief delay can make a huge difference, Wiebe said. “Even 20 minutes can give the owner enough time to circle back, and fight off their competitors.”
The birds’ behavior shows their high-risk lifestyle. They have to think twice as the holes may be hiding danger. The feathers represent possible violence, showing a predator might be inside.
The experiment reflects the lies animals tell where nest sites are rare. They build a scene so horrible to discourage nest stealers. Birds are terrified of death. And they can exploit that reality to safeguard what’s theirs.

7 . I joined the coast guard because I wanted to help people. Hovercraft (气垫船) are rare and special. They’ve been discontinued in most commercial operation, because they are so expensive to make, but when it comes to search and rescue, they’re priceless.
From far away, a hovercraft looks like a normal boat. But if you look under its skirt, the craft is not touching the water — it floats on a cushion of air. That cushion allows us to travel over everything from water to muddy land — and even break through ice. We do all of that as a 70-tonne machine, going a maximum of nearly 120 kilometers per hour. These features allow us to rescue a large number of people quickly get onto land, and get someone into an ambulance far easier than with any other device I can think of.
The advantages of hovercraft can also make them difficult to handle. We’ve got a massive vehicle moving fast, sometimes in a thick fog bank up a narrow river. During assignments on other coast guard ships, I had 20 minutes to make alterations to avoid a crash. In a hovercraft, I have 10 seconds. You have to have enough situational awareness to make the right decision every time.
People call us for all sorts of problems: missing divers, on-board fires, or even when they’ve run out of fuel or had a mechanical breakdown. A container ship could burst into flames. We have a strong network here at the base to help everyone through difficult situations like that. Thankfully, we have captains who train us in a safe environment, but you don’t ever get fully comfortable. Anything can throw the hovercraft off — maybe your lift settings are off a little, or the wind blows with a bit of extra weight. After several years operating a hovercraft, I’m still learning. Every one of the captains here agrees: you can drive this thing for 20 years and still be surprised.

8 . “Few articles change owners more frequently than clothes. They travel downwards from grade to grade in the social scale with remarkable regularity,” wrote the journalist Adolphe Smith in 1877 as he traced a coat’s journey in the last century: cleaned, repaired and resold repeatedly; cut down into a smaller item; eventually recycled into new fabric. But with the improvement in people’s living standards, that model is mind-boggling in the era of fast fashion. The average British customer buys four items a month. And it is reported that 350,000 tonnes of used but still wearable clothes go to landfills in the UK each year.
Yet the gradual revival of the second-hand trade has gathered pace in the past few years. At fashion website Asos, sales of vintage clothes (古董衫) have risen by 92%. Clothing was once worn out of necessity, and now it is simply a way of life. Busy families sell used items on eBay, teenagers trade on Depop and some fashion people offer designer labels on Vestiaire Collective. Strikingly, it has become big enough business that mainstream retailers (零售商) want a slice of the action.
For some buyers and sellers, the switch to the second-hand is born of financial difficulties. Only a few have become worried about the impact of their shopping habit on the planet. But the shift is only a partial solution. Some people worry that some mainstream brands may “greenwash” — using second-hand goods to improve their image, rather than engaging more seriously with sustainability.
However, the biggest concern may be that people keep buying because they know they can resell goods, still chasing the pleasure of the next purchase but with an eased conscience (愧疚). Boohoo, a powerful fast fashion company, has seen sales and profits rise, despite concerns about environmental problems in its supply chain that led to an investigation last year.
A new Netflix series, Worn Stories, documents the emotional meanings that clothes can have: Each old item is full of memories. Actually, a handbag from a grandmother and a scarf passed on by a father are both valuable for us. A love of style is not a bad or an unimportant thing. But a committed relationship is better than a quick flash. Can we learn to appreciate our own old clothes as well as others’?

10 . Television has transformed politics in the United States by changing the way in which information is spread, by altering political campaigns, and by changing citizen’s patterns of response to politics. By giving citizens independent access to the candidates, television reduced the role of the political party in the selection of the major party candidates. By centering politics on the person of the candidate, television accelerated the citizen’s focus on character rather than issues.
Television has altered the forms of political communication as well. The messages on which most of us rely are briefer than they once were. The stump speech, a political speech given by traveling politicians and lasting 1 to 2 hours, which was popular in the nineteenth-century, has given way to the 30-second advertisement and the 10 second “sound bite” in broadcast news. Increasingly the audience for speeches is not that standing in front of the politician but rather the viewing audience who will hear and see a short video of the speech on the news.
In these simplified forms, much of what comprised the traditional political speech of earlier ages has been lost. In 15 or 30 seconds, a speaker cannot establish the historical context that shaped the issue in question, cannot detail the probable causes of the problem, and cannot examine alternative proposals to argue that one is preferable to others. In short videos, politicians assert (断言) but do not argue.
Because television is an intimate (亲密的) medium, speaking through it requires a changed political style that is more conversational, personal, and visual than that of the old-style stump speech. Reliance on television means that increasingly our political world contains memorable pictures rather than memorable words. Schools teach us to analyze words and print. However, in a world in which politics is increasingly visual, informed citizenship requires a new set of skills.
Recognizing the power of television’s pictures, politicians craft televisual, staged events designed to attract media coverage. Much of the political activity we see on television news has been crafted by politicians, their speechwriters, and their public relations advisers for televised consumption. Sound bites in news and answers to questions in debates increasingly sound like advertisements.
