1 . At every turn in the Netherlands, the future of sustainable(可持续的) agriculture is taking shape—not in the meeting rooms of big companies but on thousands of modest family farms.
You can see it vividly on the farm run by Ted Duijvestijn and his brothers. At the Duijvestjns' 36-acre greenhouse near the old city of Delf, visitors wander among the deep green tomato plants, 20 feet tall. Rooted not in soil but in materials made from leaves and stalks, the plants are heavy with tomatoes—15 varieties in all—to suit the taste of the most demanding customers.
Since 2004, the Duijvestijns have declared resource independence on every front. The farm produces all of its own energy and fertilizer and even some of the packaging materials necessary for the crop's distribution and sale. The growing environment is kept at perfect temperatures year-round by geothermal heat(地热) that can be found under at least half of the Netherlands. Only rainwater is used for irrigation. Each kilogram of tomatoes from their plants requires less than 15 kilograms of water, compared with 61 kilograms for plants in open fields. Once each year the entire crop is regrown from seeds, and the old plants are processed to make packaging materials. The few pests that manage to enter the greenhouse are greeted by an army of fierce insects that shows no interest in tomatoes. The nutrition in the soil can be improved by growing plants that work with certain bacteria to produce their own fertilizer. In short. it's an entirely self-contained food system.
“Look at the island of Bali in Indonesia!” Ted explains. “For at least a thousand years, its farmers have raised ducks and fish within the same rice field. It's irrigated by the canal systems sculpted by human hands along mountains. They are our model.”

2 . True, people remember what you wear. After a social event, we all remember the woman in red, or the man with the top hat. On the red carpet, Hollywood hopefuls take advantage of this reality by wearing outfits designed to be discussed and displayed on the front pages of newspapers. But in terms of making a good impression, being memorable is not just about novelty or fashion, but attraction, both physical and emotional, often in opposite order of importance.
In a 2020 study, Andre Ndobo found people tended to remember the extremes: both attractive and unattractive faces. He acknowledged that one suggested explanation was that both are characterized by distinctive features that promote facial recognition when compared with faces of average attractiveness. But while distinctiveness is memorable, beauty is skin deep. Accordingly, the way you are remembered by others is often not about what you wear and how you look but about the way you make people feel.
Professional interaction can create positive personal memories. Adrie A. Koehler, in a piece entitled “In the Eye of the Beholder” (2017), found that when asked to recall their best learning experience, many students discussed a memorable teacher. What made the teachers memorable? According to the students, memorable qualities included not only teaching styles, but also interpersonal skills and positive qualities such as a sense of humor.
We can relate to the results of this study when recalling people who are memorable in our own lives. They are not always people who we believed to be the smartest or most believed, but often those who made us feel the most comfortable, and who were most interested in us. Sincere interest is uniquely attractive. Not only will you remember what someone said, but they will also remember you, fondly.
Regardless of what we wear or how we look, we are always naturally more appealing and approachable when we focus on others and when we are genuine rather than simply sociable. Remember that, and others will remember you.

3 . In a new study, shark researchers working off the eastern coast of New Zealand have found that three species of deep-sea shark are bioluminescent （生物性发光的），producing a soft blue-green light with specialized cells in their skin.
One of the species, the kitefin shark, grows to a length of nearly six feet, making it the largest known bioluminescent animal. The other two species are somewhat smaller than the kitefin, and all are occasionally caught as unintended by-catch by fishers. None are considered in danger of extinction, but little is known about their lifestyles and biology.
Bioluminescence had previously been documented in only around a dozen shark species, so this discovery significantly adds to our knowledge,,, says Jerome Mallefet, lead author of the new study.
In the deep sea, where scientists estimate three-quarters of all creatures are bioluminescent, having the ability to create light can be extremely advantageous. In the depths of the ocean, which receives minimal amounts of sunlight, bioluminescent animals can hide themselves from enemies by producing enough light to match their surroundings. All three species examined in this study have large concentrations of photocytes （发光细 胞）on their undersides, which suggests that these sharks may hide from enemies in just this way.
"The discovery that these three species produce light is not surprising", says David Ebert, director of the Pacific Shark Research Center. That's because researchers think many more species of sharks are likely capable of producing light一Mallefet estimates that perhaps 10 percent of the 540 known species of sharks are bioluminescent. But Ebert thinks even this is far from the truth. "As the deep-sea shark research advances, that number will go even higher," he says.
Both Ebert and Mallefet hope that more attention will be paid to deep-sea sharks in the future, as the creatures and their habitat are understudied and under threat. "A lot of people know that sharks can bite," says Mallefet, "but few people know that they can produce light in the dark. ”

4 . The over 48,000 orange trees that are distributed at all corners of Seville, Spain, not only fill the city's air with the pleasant smell of their flowers in spring, they also produce over 16, 500 tons of fruit every winter. Though that makes the city Europe's top orange-producing city, the fruit is too sour to be consumed fresh. While some of the produce is used to make orange juice, most of it ends up in Seville's landfills. However, that may change soon thanks to a creative idea to use the oranges to produce clean energy.
In the pilot program, juice from 38. 6 tons of oranges will be left to ferment (发酵)in an existing biogas facility. The juice is fructose (果糖)made up of very short carbon chains, and the energetic performance of these carbon chains during the fermentation process is particularly high. The gas released from the fermented liquid will be used to drive a generator to produce clean power. The officials estimate the test run will generate about 1,500 kWh of energy—enough to run a water purification plant. "It's not just about saving money. The oranges are a problem for the city, and we're producing added value from waste,M said Benigno Lopez, the head of Emasesa's environmental department.
If successful, by 2023, the city hopes to recycle all the oranges and add the electricity generated back to its grid (电网). In trial runs, 1,000 kilos (2,200 pounds) of oranges produced 50 kWh of clean energy一enough to meet the daily electricity needs of five homes. The project team estimates that if all the fruit is recycled, it will produce enough energy to power as many as 73,000 residences.
The latest effort is among the many programs implemented in Spain to achieve the country's goal of switching its electricity system to renewable sources by 2050—and if everything goes according to plan, fully decarbonizing its economy shortly after that.

6 . For many students today, distance learning has become the new normal. But distance learning means lots of screen time.
Research has shown that kids who spend a lot of time on screens are more likely to have various health problems and trouble with reading and language. Yet in the countries still suffering from the epidemic (流行病)，screens are the only safe way for many young people to learn or socialize. It's difficult for kids and teens to navigate this dilemma.
In one 2019 study, Taren Sanders, a health scientist at Australian Catholic University in North Sydney, looked at how kids spent their screen time. His group then investigated whether the type o£ screen time made a difference in health and school achievements. The researchers sorted screen time into five types: passive (such as watching a movie) , interactive (such as . playing a video game), social, educational or something else.
Educational screen time was linked to doing better in school and had no bad health effects. More passive screen time was linked to worse outcomes in health and school achievements, Sanders' group found, compared with the other categories. But the impact was quite small. Major problems showed up mainly in kids spending more than eight hours a day on screens.
The most serious problem caused by too much screen time is that people usually sit still while they are in front ,o£ a screen. "If students are spending all day sitting on screens, when are they moving?” asks Guerrero, who studies patterns of diseases. “Extended time sitting and not moving around leads to obesity, diabetes, heart disease and other health issues. So an important question to ask yourself is not how much screen time are you getting, but how active are you?"
Sanders agrees. "Overall, I'm not too concerned about the additional screen time kids are having because of distance learning," he says. “The things you should worry about: The amount of exercise they get and the way they spend their free time. "

7 . The winter had been busy and long. I desperately needed a getaway from work, so I decided to book a trip to the Caribbean with my wife. But just three days before my trip， the human-resources manager of the company called and asked to speak with me in his office. I sensed something wrong. Just months shy of my ten — year anniversary with the company, I was laid off.
I was in complete shock — too shocked to even cry. But I wouldn't cancel my trip, as I needed it now more than ever. The night before my trip, I had a dream that the suitcase I had brought to the hotel was empty. When I woke, I interpreted this dream to mean that I was leaving all of my “baggage” behind — and I did. I enjoyed my vacation more than any others I had taken. And when I was back, I decided to do one thing I loved but never had the spare time to do: writing.
My works had never been published, but I wanted to try. I wrote a few pieces and sent them out to magazines and newspapers. After several non-responses and rejections, the most-read newspaper in Canada agreed to publish one of my travel stories. I shared the thrilling news with my family and friends. People I hadn't talked to in years contacted me to tell me they read my story. How amazing!
I started writing because I liked it. What I didn't realize was that my first published story would open several doors. Being published in a major publication made my resume impressive and led to interviews for writing positions. It also led to more publications noticing the articles I submitted. I am satisfied that now I work full-time as a corporate writer and my works have been published in a number of magazines.
Getting laid off was an experience that could have been fatal （毁灭性的）,But there was something about that dream after it happened. That dream helped me put everything behind me and gave me the confidence to pursue new possibilities.

9 . At any moment, about half the world's population is wearing denim （牛仔布）. But few realize tiny bits of denim have been adding up to a surprising amount of pollution in water, as a new study shows.
Sam Athey, one of the study's authors, says, “Even though denim is made of a natural material — cotton — it contains chemicals. " Cotton fibers are treated with many types of chemicals, she notes. Some improve its durability and feel. Others give denim its distinctive blue color.
Athey and her team washed jeans and found that about 50,000 microfibers come off from each pair per wash. Not all of those fibers make their way into the environment. Wastewater treatment plants catch about 83 to 99 percent of them. Catching 99 percent may sound pretty good. But one percent of 50,000 is still 500 fibers per wash. And since every pair of jeans is washed again and again, it still adds up to lots of microfibers entering water environments.
Denim microfibers showed up in sediment （沉淀物）from the Great Lakes. More of these fibers polluted a series of shallow lakes in southern Ontario. They even turned up in sediment from the Arctic Ocean in northern Canada. The team found denim accounted for 12 to 23 percent of microfibers in the sediment. There were other microfibers too. But the team focused on denim because so many people wear jeans.
"Everyone wears jeans so they could be our largest input of microfibers into our streams and soils,“ Athey says. "An easy way to limit that is by washing our jeans less often.” Athey grew up thinking she should wash her jeans after every couple of wearings, but most jean companies recommend washing them no more than once a month “The solution is not that you shouldn't wear jeans," she says. "We need to buy fewer denim clothes and only wash them when they truly need it. ”

10 . When Emanuel received an email from Professor Richard English. Queen’s Pro-Vice-Chancellor at the School of History, Anthropology,Philosophy and Politics, encouraging him to apply for a PhD in Politics in Belfast, it was a pinch-me moment Emanual never thought would be possible. After all, just a few short years ago, he was living on the streets couch-surfing at friends’ houses and weeding gardens to make ends meet. Now, one of the world’s leading political academics was preparing to welcome him to Queen’s University over 4,000 miles away.
Emanuel never knew who his father was and his mom was mentally ill when she gave birth to him, so the hospital took him off her and he was unofficially adopted for the first few years of his life. What followed was a childhood with uncertainty as Emanuel was passed between the adoption system and family members.
Through his high school and community college years, he moved from house to house, living with friends at times and living on the streets at others.
Determined to change all that despite his rocky start in life, Emanuel involved himself in school-doing everything he could to earn extra tuition (学费) money in his spare time. But getting accepted into university was scarcely possible because a person like him couldn’t get a regular student loan.
Fortunately, the government backed him, having created a policy allowing disadvantaged persons to access funding for higher education. He graduated from the University of the West Indies with a 1st Class Honors degree and went on to do his Masters.
Emanuel knows that his story could have been very different.
“I discovered Professor Richard English online and sent him an email honestly, not thinking he would reply and to my surprise, he did. I applied for the highly competitive Commonwealth Shared Scholarship Scheme in order to fund my research at Queen’s. When I was told I was successful, my whole world changed.”
