1 . A new study by a team of researchers shows that searching to evaluate the truthfulness of false news articles actually increases the probability of believing misinformation, not the opposite.
The reason for this outcome may be explained by search-engine outputs in the study. The researchers found that this phenomenon is concentrated among individuals for whom search engines return lower-quality information.
“This points to the danger that ‘data voids’ — areas of the information ecosystem that are dominated by low quality, or even outright false, news and information — may be playing a resulting role in the online search process, leading to low return of credible information or, more alarming, the appearance of non-credible information at the top of search results,” observes lead author Kevin Aslett, an assistant professor at the University of Central Florida.
To study the impact, they recruited participants through both Qualtrics and Amazon’s Mechanical Turk for a series of five experiments and with the aim of measuring the impact of a common behavior: searching online to evaluate news (SOTEN).
The first four studies tested the following aspects of online search behavior and impact:
◎ The effect of SOTEN on belief in both false or misleading and true news directly within two days an article’s publication
◎ Whether the effect of SOTEN can change an individual’s evaluation after they had already assessed the truthfulness of a news story
◎ The effect of SOTEN months after publication
◎ The effect of SOTEN on recent news about a key topic with significant news coverage
A fifth study combined a survey with web-tracking data in order to identify the effect of exposure to both low- and high-quality search-engine results on belief in misinformation.
Across the five studies, the authors found that the act of searching online to evaluate news led to a statistically significant increase in belief in misinformation. This occurred whether it was shortly after the publication of misinformation or months later. This finding suggests that the passage of time does not lessen the impact of SOTEN on increasing the likelihood of believing false news stories to be true. Moreover, the fifth study showed that this phenomenon is concentrated among individuals for whom search engines return lower-quality information.
“The findings highlight the need for media literacy programs to ground recommendations in search engines to invest in solutions to the challenges identified by this research,” concludes Joshua A Tucker, professor of politics.

In our family, we have a beloved pet named Max, a golden retriever (寻回犬) with a heart of gold. Max has been an integral part of our family for the past five years, bringing joy, laughter, and countless precious memories into our lives. His intelligence and adorable personality never fail to bring joy and laughter into our lives. Every day, when I come home from school, Max greets me at the door with his tail wagging and his eyes sparkling with excitement. He always seems to know when I need a comforting presence, and his playful bahavior never fails to cheer me up.
Max’s intelligence is truly remarkable. He has learned numerous tricks and commands over the years, and he never ceases to amaze us with his problem-solving skills. One time, I accidentally dropped his favorite toy behind the couch, and without any prompting (提示), Max fetched a stick and used it to fish the toy out. His creativity and resourcefulness never fail to impress us.
Max’s playful personality brings endless joy and laughter into our family. Whether we are flying disc in the backyard or going for walks in the park, Max is always ready for a good time. His boundless energy and enthusiasm are contagious (有感染力的), and he has a way of making even the simplest activity feel like an adventure. His playful barks and exaggerated jumps when he’s trying to catch a ball never fail to make us laugh.
Max’s ability to sense our emotions and respond with love and affection is truly remarkable. He seems to know when we are feeling down or stressed and always finds a way to comfort us. One warm summer evening, as the sun was beginning to set, I was sitting comfortably in my living room, buried in a captivating book. Max, my loyal golden retriever, was lying peacefully beside me, enjoying a well-deserved nap. However, as the day drew to a close, Max suddenly sprang to his feet, his ears got a lift, and his eyes fixed intently on something outside the window. Without warning, he let out a series of loud, urgent barks, as if trying to alert me to a potential threat or disturbance. Alarmed by his sudden outburst, I set my book aside and joined Max at the window, curious to see what had caught his attention.

Sharks and their relatives are some of the most threatened vertebrates (脊椎动物) on Earth. Coral reefs (珊瑚礁) provide homes for countless fish species that are vital for fisheries and are therefore an especially important ecosystem for humans — and one where the decline of shark populations seems to be especially acute.
The study by Simpfendorfer with his team is the result of a worldwide collaboration called the Global FinPrint project. The data analyzed include more than 20,000 hours of standardized underwater video taken at nearly 400 reefs in 67 countries around the world. It reveals declines of 60 to 73% of once-abundant coral reef shark species at reefs around the world. The global conservation status of sharks and rays (鳐鱼) is worse than a decade ago and is even more concerning for some groups of sharks.
However, the findings of Simpfendorfer with his team include signs of hope and a clear path forward. Their results show that although shark populations in many reefs had declined, some healthy reef shark populations remained. The reefs with healthier shark populations had some important similarities: They tended to be in the waters of high-income countries with stronger natural resource management regulations. Unfortunately, such countries are relatively rare, and lower-income countries tend to have fewer resources for sustainable management.
The most unexpected result of the study is that a decline or complete loss of shark species in one reef was not always associated with similar changes in nearby reefs. They found that one reef can be overfished so badly that a once-common reef shark species is totally gone, but another reef a short distance away can have healthy populations of that same species.
The problem is clear — animals that provide ecosystem services that are vital for human food security and livelihoods are disappearing at an alarming rate. The loss of sharks and the ecosystem services they provide represents an ecological disaster that can cause substantial harm to humans.

4 . More than one-third of the world’s food is wasted or thrown away, most of which ends up in landfills, producing very large amounts of planet-warming greenhouse gases. Now, many studies show that it is becoming harder to grow enough food to feed an increasing population due to climate change and soil degradation.
But one of the most promising and simplest solutions lies in the problem itself: this wasted food — if composted (堆肥) — could slow climate change and improve soil quality. Higher-quality soil also continues to absorb more carbon from the atmosphere, helping to improve plants and contributing further to fighting climate change. Returning one ton of organic matter to each hectare of soil would increase the production of cereal crops each year in Africa, Asia and South America by millions of tons.
While it is true that people can compost in their yards, community gardens, or even on their kitchen counters, larger-scale efforts, including infrastructure (基础设施) and incentives (激励) for consumers, would take it to the next level. Imagine if consumers could just leave unwanted food in a roadside bin for pickup, or drop it off at a local store, earning a few cents a bucket, just like what has been offered for recycling bottles or newspapers.
Moreover, in the case of composting, the payment incentive system would be sustainable because the end-product of compost can be sold to farmers, making it an economically workable model, something that is often lacking in recycling, especially for certain materials, like many types of plastics.
Eventually, more widespread composting of food would pave the way for solutions to additional waste challenges, such as the disposal of packaging and clothing. This will have other positive effects as well; if more consumers compost, companies will be more inspired to make and use compostable packaging, clothing, and other products. While more compostable items are starting to emerge today, additional composting will further drive demand and innovation, and offer a game-changing solution for the planet.

5 . Roald Hoffmann, a Nobel Prize winner in chemistry, poet and playwright (剧作家), is a tireless advocate of the wonders of science and the beauty of chemistry. Hoffmann successfully shares his understanding of science with the public at large through literature, educational television and even the stage. Here is an article he wrote:
Around the time of the Industrial Revolution, science left poetry. Nature and the personal became the main playground of the poet. That’s too bad for both scientists and poets, but it leaves lots of open ground for those of us who can move between the two. If one can write poetry about being a tree, why not about being a scientist? It’s experience, a way of life. It’s exciting.
The language of science is a language under stress. Words are being made to describe things that seem indescribable in words — equations (方程式), chemical structures and so forth. Words do not, cannot mean all that they stand for, yet they are all we have to describe experience. By being a natural language under tension, the language of science is inherently (内在地) poetic. Emotions emerge shaped as states of matter and more interestingly, matter acts out what goes on in the soul.
One thing is certainly not true: that scientists have some greater insight into the workings of nature than poets. Interestingly, I find that many humanists deep down feel that scientists have such inner knowledge that they don’t. Perhaps we scientists do, but in such carefully circumscribed pieces of the universe, poetry flies high, all around the tangible (有形的), in the deep dark, through a world we reveal and make.
It should be said that building a career in poetry is much harder than in science. In the best chemical journal in the world, the acceptance rate for full articles is 65%, for communications 35%. In a routine literary journal, far from the best, the acceptance rate for poems is below 5%.
Writing has become increasingly important to me. I expect to publish four books for a general or literary audience in the next few years. Science will be involved, but only as a part, a vital part, of the risky project of being human.

The Charm (魅力) of Schoolyard
In the charm of school life, where classrooms are seats of knowledge and the schoolyard becomes source of memory, there are a fund of stories mixed with humor, warmth, and teacher-student relationships.
Mr. Smith was a country teacher, but not an ordinary one; he was a storyteller, a mentor (人生导师) , and a friend to all his students. His classroom was a world of its own, full of colorful characters and brilliant ideas. One day, during the noon break, a student named Alice noticed a wandering kitten padding (潜行) through the familiar grounds where many schoolyard tales were born. Alice took her to Mr. Smith, who had magical Tricks for handling even the smallest things. With Mr. Smitt’s permission, Alice and her classmates built a shelter for the kitten in a corner of the campus.
The days turned into weeks, and the kitten grew under the tender care of Mr. Smith and his students. Once in a while, she became a temporary resident of the classroom, much to the delight of the whole class. They named her “Schoolyard”, a name that generalized the spirit of their school days.
As the year progressed, Schoolyard became not just a kitten, but a tie connecting each of them and a thread of continuity in their lives. She played on desks, slept in chairs, and hid in folders, thus becoming an unofficial mascot (吉祥物) of the classroom. The students found comfort in her presence, and Mr. Smith, joy in watching them grow through her company.
As graduation neared, Mr. Smith gathered his students for one last lesson. He told them that they would soon be exploring new horizons. He reminded them that life was full of unforeseeable twists and tums along with unexpected potentials, just like the appearance of a kitten in their schoolyard. At the moment, the students were greatly touched and deep down there arose a strong love for those memorable warmth and hearty laughter of their school days.
Thereafter, Mr. Smith and the students agreed to meet here once again in ten years.

________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________After a long drive and precious little sleep, Todd left his Wisconsin motel around 5:30 a.m. to make it to a funeral near Green Bay. Not long after, he started to hear a grinding sound coming from his front tire, and it kept getting louder. He finally pulled into Lauritzens BP & Sports shop in Wild Rose,Wisconsin, hoping to find help. It was only 7 a.m., and he still had 75 miles to go.
As luck would have it, Todd found Glenn Geib putting oil on the shelves. The mechanic checked out the car and gave Todd some bad news: The wheel bearing was failing and needed to be repaired right away. Fixing it would take a few hours. Geib then looked Todd up and down and asked why he was so dressed up. Todd explained that he was going to the funeral of his boss’s wife.
Geib checked the only one rental car agency in town, but it was sold out. The next closest rental agency was 40 miles away. “I must have looked pretty stressed out at this time,” Todd wrote later on Facebook. Geib noticed, and he was determined to help.
With a population of 699, close-knit Wild Rose has a reputation in central Wisconsin for kindness. Seniors gather at the Wild Rose Community Center for free midday meals. The local Lions Club chapter collects used eyeglasses for folks who can’t afford them, part of the Lions Recycle for Sight program.
But kindness in Wild Rose doesn’t come just from organizations. Kent Barnard, the town library director, remembers a high school kid who walked into Patterson Memorial Library needing gas money. Barnard happily gave it to him, and the guy went on his way. A couple years later, that man came back. “You gave me $10 for gas when I was in high school,” he said, and Barnard was repaid.
“People are not well-off, but they’re taking care of each other,” says Jerry Apps, a local author who lets the library sell his books and DVDs and keep some of the proceeds to fund its programs.

Established earthquake warning systems provide at best just a minute or two of notice, leaving little time for preparedness. Decades of searching for a better warning sign-changes in the geochemistry of groundwater, electromagnetic effects in the upper atmosphere, and even changes in animal behavior-have failed. Many question whether such a precursor (先兆) even exists. This situation may change soon, as recent research is providing a glimmer of hope for improved earthquake prediction.
Researchers Quentin Bletery and Jean-Mathieu Nocquet from Cote d’Azur University in France collected data from over 90 earthquakes with magnitudes larger than 7 that had occurred in the past two decades.They focused on GPS station records near these quakes, which accurately captured land movement every 5 minutes with millimeter precision. They analyzed more than 3,000 time series of motion in the 48 hours leading up to the main ruptures (断裂).
They noticed that, in the first 46 hours, the records showed no significant features. However, during the 2 hours before the earthquake, they noticed signs of increasing movement along the fault zones (断层带). Essentially, there’s a slip between plates causing the land above them to move in a measurable, horizontal direction.
Could this be just a coincidence? The probability of this increase happening just before the quake and being unrelated is extremely low, and the researchers confirmed this by analyzing 100,000 random time windows in non-earthquake GPS data. The pattern occurred only 0.03% of the time in non-earthquake data.
While this precursor signal won’t be used for warnings anytime soon, officials from the United States Geological Survey (USGS) admit that this new study provides valuable insights into how to improve their warning systems-GPS data can grease the wheels of early earthquake warnings.
The researchers admit they're still a number of steps away from putting this precursor signal into use, particularly since detecting subtle signals at individual faults requires more GPS stations. But the biggest problem is that many of the world’s earthquake regions have no instrumentation. “We can’t realize the detection at the scale of one earthquake, so we cannot make predictions,” Bletery said.

9 . P. H. Hanes, founder of HanesBrands, came up with retail price in the 1920s. That allowed him to use ads in publications across America to discourage distributors from unfairly raising the price of his knitted underwear. Even today many American shopkeepers stick to manufacturers’ recommended prices, as much as they would love to raise them to offset the inflationary (通货膨胀) pressures on their other costs. A growing number, though, resort to more complicated pricing techniques.
Getting retail price right can be tricky. Set prices too high and you risk losing customers; set them too low and you leave money on the table. Retailers have historically used rules of thumb, such as adding a fixed margin (差额) on top of costs or matching what competitors charge. As energy, labour and other inputs go through the roof, they can no longer afford to treat pricing as an afterthought. To gain an edge, shopkeepers have been turning to price-optimisation systems.
At their core are mathematical models that use deal data to estimate price flexibility—how much demand increases as the price falls and vice versa—for thousands of products. Price-sensitive items can then be discounted and price-insensitive ones marked up. Merchants can fine-tune the algorithms (算法) to prevent undesirable outcomes.
These systems are becoming cleverer thanks to advances in artificial intelligence(AI). The latest crop of AI-powered ones can spot patterns and relationships between multiple items. Makers of pricing software are incorporating new data sources into their models, from customers’ tweets to online product reviews, says Doug Fuehne of Pricefx, one such firm. In February Starbucks, a chain of coffee shops, boasted about its use of analytics and AI to model pricing “on an ongoing basis”. US Foods, a food distributor, praised its pricing system’s ability to use “over a dozen different inputs” to boost sales and profits.
What pricing systems do not do is lead unavoidably to higher prices. Matt Pavich of Revionics, another pricing-software firm, calls this misconception “one of the biggest misunderstanding” about products like his. Sysco, a big food distributor which rolled out new pricing software last year, is a case in point. The firm says the system allows it to lower prices on “key value items”—as price-sensitive bestsellers are known in the trade—and raise them on other products. It can thus increase profits by expanding sales while maintaining margins.
