Their beautiful call suggests the arrival of spring, but the routes taken by cuckoos(杜鹃) during their annual migration(迁徙) have remained a mystery. Now, though, scientists from the British Trust for Omithology(BTO) have revealed the details of their remarkable 10,000-mile journey, with the help of tracking devices.
Five male birds were caught in Norfolk last May and fitted with satellite-tagged “backpacks’’ before being released. The scientists then monitored their progress over 12 months as they flew to Africa in the autumn, and returned in the spring.
The project was carried out to discover why every year fewer of the birds return to Britain. Between 1995 and 2010,the population of cuckoos spending summer here fell by almost half, and the number is continuing to decline. Previously, the lack of information about the cuckoos’ long migration has hampered the understanding of how to help conserve the birds.
Earlier this year, it was reported that cuckoos arrived in the UK much earlier than normal. Their call was recorded by ornithologists(鸟类专家) as early as February, a month ahead of their usual arrival.
Like all migrating animals, cuckoos respond to the changing seasons. They depend on lush plants to provide the fruit and food for insects that they feed on. This reliance on seasonal patterns means that a changing climate could make an already challenging journey impossible for them.

【推荐1】The opening of California’s commercial crab season, which normally starts in November, is delayed once again to protect whales searching for their prey (猎物) along the coast.
California has been affected by a marine heat wave since May. The Blob, as this mass of warm water has become known, is squeezing cooler water preferred by whales and their prey close to shore, where fishermen set their traps. This crowding can lead to tangle (缠结) between whales and fishing equipment, endangering the animals’ lives and requiring rescue missions.
In a new study, scientists say they can now use global temperature models, commonly used in climate science, to predict up to a year in advance when hot ocean temperatures raise the risk of tangles between whales and fishing equipment.The tool analyzed in the new study, called the Habitat Compression Index, works by feeding sea-surface temperature measurements into an equation (方程式) that estimates the likelihood of whale habitat shrinking closer to shore.Regulators and fishermen agree that the new forecasting research could help them walk the tightrope between protecting whales and protecting local livelihoods (生计).
Mr Ogg, a commercial fishing boat captain, describes himself as a conservationist who doesn’t want to see whales harmed.“Fishermen have a big motivation to protect the natural environment,” he said, “because that’s where they make their living.” Previously, the challenge was adapting to changing conditions and fishing regulations on short notice, especially for smaller business owners and their crews.“One of the biggest problems we had was the unpredictability,” Mr Ogg said, “We were living from week to week then.”
Though scientists have shown the Habitat Compression Index can now forecast months in advance, state officials would probably wait to see conditions in real time before making decisions about the crab fishery, said Ryan Bartling, an environmental scientist at the California Department of Fish and Wildlife.

【推荐2】The most obvious dog fetish (迷恋) today is the longing for cuteness. Almost every day you can see adorable pictures of dogs and other animals that will make you smile and say, "How cute!"
It is a cultural phenomenon that the media scholar James Meese calls the "cute economy" which exists primarily on social media, is user-generated, and is heavily dominated by pictures of animals, especially pets. The goal is to generate a positive response, probably followed by a tap on the screen to "like" and "share". We can click through image after image of cute animals doing cute things, feeling a little boost of good cheer.
The marketing researchers have identified some of the most common categories of cuteness in online pet content: animals doing silly things; animals of extreme size; animals with unusual looks; and animals behaving in ways that seem human-like. Dogs and other animals in the "cute economy" are often further humanized by being dressed in clothing and accessorized (装饰) with hats, jewellery, nail polish and fur dyed a rainbow of colors. Users who post successfully and with some strategies can make money by doing so. Thus, certain dogs have become cuteness celebrities, with millions of devoted followers and paid content from advertisers.
Unfortunately, the price of the "cute economy" comes at a serious cost. The cutest and most popular breeds tend to be those with the most significant risk of health and behavioral problems. Cuteness is often coupled with their discomfort. People are drawn to the cuteness of dogs with extremely foreshortened skulls and extremely short legs and awkwardly long bodies, such as the French bulldog and the corgi
Actually, there are well-established health issues. We should treat the "cute economy" with caution, like resisting the commodification (商品化) of appearance by opting out of social media channels promoting the "cute economy". We can also choose not to "like" or "share" images of dogs whose cuteness is linked with discomfort. Although we are biologically attracted to dogs that are super cute, we should be mindful in our "impulses".

【推荐3】The World Wide Fund For Nature is concerned about the many species of wildlife that are dying out around the world.
Currently, illegal hunting of wild animals for their valuable parts is still one of the biggest drivers of extinction. Demands for elephant ivory carvings, tiger bone wine and traditional medicine such as rhino horn (角) continue to cause these most endangered animals to die out.
There is still an enormous market for chimpanzee body parts in Africa — for example in Nigeria, a chimpanzee head will sell for $100 at the market. When it exists, it is no surprise that organized crime networks get into the game. The rise in rhino poaching (偷猎) over the past decade has been alarming: between 2016 and 2020, rhino poaching in South Africa increased by an astonishing speed, from just 130 animals in 2016 to 1215 in 2020, making the species functionally extinct.
When it comes to figuring out where illegal hunting is taking place,conservationists face many challenges. But development in technology is putting new tools into the hands the conservation biologists who so eagerly need them, using AI (artificial intelligence), such as machining learning, or drones (无人机). And another solution that Founding Co-director of the University of Southern California Center Professor Milind Tambe came up with is to apply the tools in his work.
The system called PAWS (for Protection Assistant for Wildlife Security) was developed to catch poachers, featuring more than 125,000 observations on animal remains, traps and more — all with GPS coordinates (坐标). Tambe and his team were able to create a system that would predict likely hot-spots for poaching and direct patrols (巡逻) there to get rid of traps before they can kill any animals.
“After researching in the lab, we tested our system in Uganda to show it could work,” he says. “Sure enough, we did seek out snares (捕鸟、兽的陷阱;圈套) and a poached elephant on the spot.” However, Professor Tambe says, “PAWS is just the start. Much remains to be done. What conservationists really need is to continue to dismantle traps, catch poachers in the act, and effectively monitor areas to prevent poachers from approaching animals.”

【推荐2】The research company OpenAI has recently released ChatGPT, a language model that can construct remarkably well-structured arguments based on simple cues provided by a user. The system which uses a massive source of online text to predict what words should come next is able to create new stories in the style of famous writers, write news articles about itself and produce essays that could easily receive a passing grade in most English classes.
That last use has raised concern among academics, who worry about the possibility of an easily accessible platform that, in a matter of seconds, can put together essays as good as -- if not better than -- the writing of a typical student.
Cheating in school is not new, but ChatGPT and other language models are totally different from the hacks(雇佣文人)students have used to take a shortcut in the past. The writing these language models produce is completely original, meaning that it can’t be distinguished by even the most advanced plagiarism(剽窃)software. The AI also goes beyond just providing students with information they should be finding themselves. It organizes that information into a complete narrative.
Beyond potential academic honesty issues, some teachers worry that the true value of learning to write -- like analysis, critical thinking, creativity and the ability to structure an argument -- will be lost when AI can do all those complex things in a matter of seconds.
“We might know more things but we never learned how we got there. We’ve always said that the process is the best part and we know that. The satisfaction is the best part. That might be the thing that’s removed from all of this. Actually, I don’t know what a person is like if they’ve never had to struggle through learning. I don’t know the behavioral implications of that,” said Peter Laffin.
“Whenever there’s a new technology, there’s a panic around it. It’s the responsibility of academics to have a healthy amount of distrust, but I don’t feel like this is an undefeatable challenge,“ Sandra Wachter, technology researcher, said.

【推荐3】The earliest newspapers started in ancient Rome. They were handwritten news sheets. The first printed newspapers appeared in China during the Tang dynasty, which were printed from carved wooden blocks. Modern papers first appeared in Venice, Italy in the middle of the 14th century. The newspapers of today, with advertising and a mixture of political, economic, and social news and comments, were started in Britain in the mid-18th century.
The main function of newspapers is to report news. Many newspapers also provide special information to readers, such as weather reports and television timetables. They also provide comments on politics, economics, arts and culture. Almost all newspapers depend on advertising to make money. Nearly six out of ten adults in the United States and Canada read a newspaper every day. Seven out of ten read a paper each weekend. Readers search newspapers for detailed background information and analysis. This is what television and radio news reports seldom offer. Newspapers tell readers what happened, and they also help readers understand what caused an event and how it will affect the world around them.
The workers at large newspaper companies work under a lot of stress to bring news to readers as soon as possible. Reporters, photographers, artists, and editors collect articles in just a few hours. Page designers select articles, photos, advertisements, and eye-catching headlines to make the pages, and then rush their work to the printer. Printing workers may work overnight around printing presses to churn out more than 60,000 copies per hour.

Christmastime in the city brings forests of trees already cut and waiting to be sold. But some people like to drive to tree farms. Others wait for their trees to come to them. They order one from the pages of a catalog or on the Internet. Some say the easiest thing of all is to buy a manmade tree with Christmas lights already on it. No falling needles to have to clean up.
The National Christmas Tree Association says 33,000,000 real trees were sold last year, compared to 9,000,000 manmade ones. Manmade trees generally cost more, but they can be reused. Most natural trees are cut up and recycled, but some people buy trees that can be planted.
Most Christmas trees are now grown on farms instead of in forests. Twenty-one thousand tree farmers in the United States grow Christmas trees on more than 180,000 hectares. Oregon was the leading producer last year.
Twenty-two percent of people who bought real trees last year chose them at a farm. Two percent of those people cut the trees themselves. The next most popular places were big stores like Walmart and Home Depot. Groups like the Boy Scouts also sell Christmas trees. But some people pay nothing for theirs. They steal it.
Cornell University in Ithaca, New York, has many pretty evergreens. Some years ago, a university worker found a way to keep them there. A month before Christmas, workers treated them with “pink ugly mix”. It contains water and red food colour. The bright colour starts to disappear after about a month. It can take longer, however. Cornell decided not to use the mix this year, but the idea has spread.

【推荐2】Leisure is the prize, right? We work hard, so we want to play hard; we look forward to our time off, believing that the more leisure time we have, the better life will be.
However, research shows that both having and deciding how to spend leisure time can be very stressful. Some people feel enormous pressure to make the best use of their free time with the best choices. But this pressure to maximize our fun might impede the enjoyment of leisure itself.
Two-thousand years ago, concepts of work and leisure were associated with slavery(奴隶制)and freedom, respectively. In Ancient Greece, most of work was done by slaves, while wealthier parts of society pursued other activities. Leisure was an active state of mind. Good leisure meant playing sports, learning music theory, debating with qualified partners, doing philosophy, etc. Leisure was not easy, but it was supposed to be satisfying.
A shift occurred when the Romans started viewing leisure as a way of getting back energy in preparation for more work. By the 1800s, the kind of leisure that showed social class had shifted too; the wealthy led extremely free lives. A popular example is Walter Benjamin’s description of the fashion, around 1893, to walk through streets with a turtle (乌龟)on a chain.
Today we’re seeing yet another change: a lack of leisure time now operates as a powerful social class symbol. On Twitter, celebrities complain about having no life and being in desperate need of a vacation. In the workplace, being part of the long-hours working culture is still seen by many as an honour.
Some people really struggle to enjoy time off. People from America support the belief that leisure is wasteful. Only 14% of Americans take two weeks’ vacation in a row, a finding in keeping with the overwork culture. The same study reports that as of 2017, 54% of American workers didn’t use up their vacation time, leaving 662 million days reserved for leisure unused.

【推荐3】In 1945, two sculptures meant to represent the average man called Norman and woman called Norma in the United States went on exhibit at the American Museum of Natural History.
That same year, a contest was launched to find a living representation of Norma. Normal is often used to mean “typical”, “expected”, or even “correct”. By that logic, most people should fit the description of normal. And yet, not one of almost 4,000 women who participated in the contest matched Norma, the supposedly “normal” woman.
This puzzle isn’t unique to Norma and Norman, either — time and time again, so-called normal descriptions of our bodies, minds, and perceptions have turned out to match almost no one. So what does normal actually mean — and should we be relying on it so much?
In statistics, a normal distribution describes a set of values that fall along a bell curve (曲线). The average, or mean, of all the values is at the very center, and most other values fall within the hump (驼峰) of the bell. Normal doesn’t describe a single data point, but a pattern of diversity. Many human traits, like height, follow a normal distribution. Some people are very tall or very short, but most people fall close to the overall average. Outside of statistics, normal often refers to an average like the single number pulled from the fattest part of the bell curve that excludes all the nuances of the normal distribution. Norma and Norman’s proportions (比例) came from such averages.
Applied to individuals, whether someone is considered normal usually depends on how closely they get to this average. At best, such definitions of normal fail to capture variation. When limited or inaccurate definitions of normal are used to make decisions that impact people’s lives, they can do real harm. There were examples in history.
To this day, people are often targeted and discriminated against on the basis of disabilities, mental health issues, and other features considered “not normal”. But the reality is that the differences in our bodies, minds, perceptions, and ideas about the world around us — in short, diversity — is the true normal.
