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.
