1 . Deserts could be the best places on Earth for harvesting solar power. They are spacious, relatively flat, and never short of sunlight. So researchers imagine it might be possible to transform the world’s largest desert, the Sahara, into a large solar farm, capable of meeting four times the world’s current energy demand.
While the black surfaces of solar panels absorb most of the sunlight that reaches them, only around 15% of that incoming energy gets turned into electricity. The rest is returned to the environment as heat, affecting the climate. If these effects were only local, they might not matter in a thinly populated desert. But the area of the installations in the Sahara would be vast, covering thousands of square miles. Heat released from an area this size will be redistributed by the flow of air in the atmosphere, having regional and even global effects on the climate.
A 2018 study used a climate model to assess the effects of building massive solar farms in the Sahara. The model revealed that when the size of the solar farm reaches 20% of the total area of the Sahara, the heat released by the darker solar panels creates a big temperature difference between the land and the surrounding oceans that ultimately lowers surface air pressure and causes wet air to rise and condense (凝结) into raindrops. With more rainfall, plants grow and the desert reflects less of the sun’s energy since vegetation absorbs light better than sand and soil. With more plants present, more water is evaporated (蒸发), creating a better environment that causes vegetation to spread.
So, a large solar farm could generate enough energy and at the same time turn one of the most abominable environments on Earth into a habitable place. Sounds perfect, right? Not quite. In a recent study, we used an advanced Earth system model to closely examine how Saharan solar farms interact with the climate. It showed there could be unintended effects in remote parts of the land and ocean.
We are only beginning to understand the potential consequences of establishing massive solar farms in deserts. Solutions like this may help society reduce the use of fossil energy, but Earth system studies like ours underscore the importance of considering the numerous coupled responses of the atmosphere, oceans, and land surface when examining their benefits and risks.

2 . A complete chicken egg estimated to be around 1,700 years old is believed to be the only of its type in the world, after scientists found it still had liquid inside.
It was discovered during a dig in Aylesbury in Buckinghamshire between 2007 and 2016, with researchers saying at the time that it was a “genuinely unique discovery”. During the course of the dig, archaeologists broke three other eggs which released a “terrible smell”, but a fourth egg remained undamaged. It is the only complete egg ever found dating back to the Roman times.
Now, a micro scan has found that the egg still contains the yolk (蛋黄) and egg white, and it is believed to be the only complete egg from that period. The recent work has been carried out by conservator Dana Goodburn-Brown, who took the egg for further analysis at the University of Kent.
Edward Biddulph, senior project manager at Oxford Archaeology, who oversaw the dig, said, “It produced an amazing image that indicated that the egg, apart from being complete — which is incredible enough — also held its liquid inside. We were absolutely blown away when we saw the contents in there, as we might have expected them to have leaked out.”
It has also been taken to London’s Natural History Museum, where Douglas Russell, the senior director of the museum, was consulted about how to conserve the egg. Mr Biddulph said, “As we found out when we visited the Natural History Museum, it appears to be the oldest known example in the world.”
The egg is now being housed at Discover Bucks Museum in Aylesbury while work continues to discover how to extract (提取) the inside without breaking the delicate shell.
“There is huge potential for further research and this is the next stage in the life of this remarkable egg,” Mr Biddulph said.

3 . Which of these ingredients have you cooked with or eaten, wild rice, rabbits or roses? Actually, they were part of Native American cuisine in the past. Sean Sherman is a chef from the Oglala Lakota tribe, who is attempting something remarkable. Through his company and his restaurant, Sherman is bringing these ingredients back into the public eye.
Sean Sherman grew up on the Pine Ridge Reservation. As a reservation kid, Sherman usually didn’t have access to high-quality or tasty food. His family relied on the Commodity Supplemental Food Program, which meant canned goods, tasteless food, and powdered milk. After high school, Sherman started working for the Forest Service. As part of his job, he had to learn the names of the plants, which raised his curiosity about indigenous (本土的) plants and foods.
Sherman started doing lots of research on his own, and he started his company in 2014. A few years later, Sherman opened his restaurant Owamni, where he showed native ingredients and flavors. The most significant feature of the restaurant is the native ingredients, none of which is related to European civilizations.
The vibe in the restaurant is totally unique as well. There, a lot of people are really struck by it, because it’s not typical to be able to go someplace and see their native foods on the menu, see native people cooking the food and listen to native music. Therefore, it’s a wholly unique experience and it’s something that’s really special.
Native cuisine allows native people to explore their histories and cultures. It supports local businesses and comes with a host of health benefits. “We should have native restaurants in every city to show the diversity and flavors of all the different tribes across North America and thus have a future where native cuisine is more widespread, and ingredients are more familiar and well known,” Sherman explains.

4 . Li Jing, 29, currently serves as the director assistant to the village secretary of Maotianping Village Committee in Cuijiaba, a town in Hubei province. Li is a native of this village and was one of the first from her community to achieve higher education. She studied hotel management and tourism. After graduation, she started a career in the hotel industry in Wuhan. However, she made a decision last year to return to her village. She wants to be an essential part of her hometown’s development, realizing her own personal value.
When Li returned to her hometown, she received unconditional support from her family, despite some villagers’ questioning her decision. She resolved to prove herself through determination and action.
Her job involves extensive communication with the villagers, with over half of her workload about promoting potato production, the main business of the village. Li and the villagers regularly hold meetings in the village square, where they share insights on potato planting techniques, sales channels, market trends, and more. These gatherings provide her with opportunities to equip the villagers with planting tools and offer a window for them to voice their concerns and experiences.
In her spare time, Li remains closely connected with the villagers through regular conversations. She admits that it demands a considerable investment of time and energy, but it’s all worthwhile.
Li has very fond memories of an incident from last year when one villager had a poor potato crop. Although her potatoes were unimpressive in terms of size and quality, she held faith in Li and worked tirelessly and enthusiastically. Li never forgets the smiles on the villagers’ faces at harvest time, which is the ultimate reward for her.
In the near future, Li hopes to continue helping her fellow villagers raise their potato production and increase their income. Her long-term vision is to promote urban-rural integration (整合).

6 . Now it seems that more and more animals are showing up in cities where we would not expect them to. But scientists have learned that some species do better in cities. Take peregrine falcons (游隼) for example. They use tall city buildings to make homes, man-made lighting to hunt at night, and warm air currents created when the sun beats down on city surfaces to fly with less effort.
Some animals adapt well to city life, and some do not. For example, squirrels (松鼠) do amazingly well living in cities, while wolves have never seemed to get the hang of it. Usually, animals that eat a lot of different things, called generalists, do much better in cities than specialists, which eat one specific kind of food. Smaller animals are also more likely to live in cities than bigger animals. Some people believe animals that do well in cities might be smarter than the ones that do not, but more research is needed on this.
Many animals have even learned cool tricks to live in cities, and these behaviors help them find more food or mates (伴侣), or avoid people. To learn about these behaviors, we use recording devices to spot animals, microphones to record their sounds, and tracking equipment to follow them. Scientists use many different tools to study what animals eat, how healthy they are, how they compete with each other, and more.
Humans are turning the planet into cities and farms, which does not leave many other places for most wildlife to live in. So, what can we do? At home, we can cover our garbage carefully because it is not good for wild animals. We can also plant some native plants that wildlife might like. Seeing animals in a city, we can give them space and watch them from far away. We could also try some creative things like green roofs where birds and insects can live in.
To do that, we need to know what kind of habitats different species need, and how to prevent human-wildlife conflicts. We still have a lot to learn.

9 . Brewing Up the Best Cup of Coffee
Editor’s note: In the world of coffee, there is a hierarchy (等级) based on brewing (酿制) methods and coffee bean quality. Manual brewing is superior to machine brewing. Italian-style coffee is usually preferred over the American style. At the top of this world, it is specialty coffee (精品咖啡). And becoming a specialty coffee barista (咖啡师) requires specific training. Let’s go to the story of one such barista.
To customers, specialty coffee may be just a simple drink, but for specialty coffee baristas, it is a demanding science. Fei Teng, a 35-year-old barista with 10 years of experience, considers various factors like altitude, climate and grinding (研磨) when making specialty coffee. Fei also has his own principle of developing creative coffee. The Salty Mocha, created by Fei, gained popularity among coffee enthusiasts. “The sea salt neutralizes the sweetness of the mocha, adding layers of flavor to the taste. By introducing innovative changes to classic coffee, it can bring new and wonderful experiences to the taste buds,” Fei told Teens.
Fei majored in fine arts in college but chose to become a coffee apprentice (学徒) after graduation. He began by learning the basics of coffee, including its varieties and roasting levels. Through training and participating in competitions, Fei improved his barista skills, like grinding beans and frothing milk (打奶沫). “Becoming a barista is easy to get started, but difficult to master,” said Fei. To enhance his sensitivity to the quality of coffee beans, Fei tasted a wide variety of coffee, often drinking more than 20 cups a day. That led to diarrhea (腹泻)at times.
“In addition to coffee knowledge, service skills are crucial but often overlooked by baristas,” Fei said. Baristas need to patiently address customer questions and convey the concept behind their coffee in an attractive manner. “Some baristas even create music introductions for their coffee and share them with customers,” added Fei.
“Many view being a barista as a cool job, but actually, it is quite hard and there is a lot of physical labor, like cleaning the cafe,” Fei said. However, despite the challenges, career prospects are promising. A 2023 report reveals that Chinas coffee industry reached 200.7 billion yuan in 2022.
Having dedicated a decade to the coffee industry, Fei plans to continue focusing on specialty coffee and further contribute to the growth of the Chinese coffee sector.
