1 . We are in the midst of a battle for our attention. Our devices have affected our brains and destroyed our collective ability to concentrate. Journalist Johann Hair’s new book, Stolen Focus, has just joined the voices complaining about the great influence of the digital age. His and other recent books reflect a public perception that our focus is under attack.
Indeed, in our new research, we found some clear concerns. We surveyed a nationally representative sample of 2,093 UK adults in 2021. Half of those surveyed felt their attention spans were shorter than they used to be, compared with a quarter who didn't. And three quarters of participants agreed we're living through a time when there's non-stop competition for our attention between a variety of media channels and information outlets (渠道).
There has long been a worry about the threat to attention brought by new cultural forms, whether that’s social media or the cheap paperback sensation novels of the 19th century. Even as far back as ancient Greece, the philosopher Socrates complained that the written words created “forgetfulness in our souls”. There has always been a tendency to fear the effects that new media and technologies will have on our minds.
The reality is that we simply don’t have long-term studies that tell us whether our attention spans have actually shrunk. What we do know from our study is that people overestimate some of the problems. There’s no such thing as an average attention span. Our ability to focus varies hugely depending on the individual and the task at hand.
It’s also important not to ignore the many benefits that technology brings to our life. Much of the public surveyed recognized these, so while half thought big tech and social media were ruining young people’s attention spans, roughly another half felt that being easily distracted was more to do with people’s personalities than any negative influence that technology may or may not have. Also, half of the public believed multitasking at work and switching frequently between emails, phone calls, and other tasks can create a more efficient and satisfactory work experience.

5 . Every spring, in regions at high altitudes around the world, one of Earth’s tiniest migrations takes place. The migrants are single-celled green algae (海藻); they are relatives to plants growing in the sea, but instead of living in the sea they live in snow. They spend the winter deep in the snow. In the spring, they wake and swim up through flowing streams of melted snow to the surface, dividing and photosynthesizing (进行光合作用) as they go. Then, at the top, they turn red. This creates what scientists call pink snow.
The color comes from astaxanthin (虾青素), a substance that gives some living things their reddish color. The algae produce astaxanthin as a form of sun protection; it absorbs UV light, thereby warming the organisms and thus melting the surrounding snow. “The melting helps them a lot,” said Roman Dial, a biologist at Alaska Pacific University. “The moment there is liquid water on the snow, the algae start growing.”
Pink snow is a perfectly natural phenomenon, but in an age of disappearing glaciers (冰川), it is also problematic. Last year, scientists discovered that the algae turned the snow surface dark, reducing the amount of sunlight reflected by some glaciers in Scandinavia—and increasing the amount of sunlight absorbed—by 30%. The result, as Dial and his colleagues demonstrated in this month’s issue of Nature Geoscience, is faster melting. As in other parts of the warming planet—particularly the Arctic, where scientists fear that melting permafrost (永冻土层) may lead to further climatic changes. Ice sheets are already being darkened by dust and ash, which makes the process of melting faster and provides nutrients for algae growth. As the organisms multiply, they melt even more snow, which allows them to increase in their population again. “It spreads more rapidly than people realize, once it gets established,” Dial said.
Snow algae need snow; when that’s gone, which seems to be the direction of things, the snow algae will go, too. Before the snow algae disappear, though, and while there’s still some glacier left, it’s entirely possible that the last snow we’ll see on Earth will be pink or even red, a wound on Earth.

8 . In his senior year of high school, Wei Fangjie happened to see a poster for recruiting (征募) PLA Air Force pilots. “The pilots on the poster looked really cool, and I got to know that a pilot is known as a profession of the brave. So, I decided to give it a try,” said Wei, 26, who now works as a flight instructor at the Air Force Aviation (航空) University.
According to Wei, pilot students need to not only study aviation theory but also practice difficult aerobatics (飞行特技), which require strong resistance to gravity force. “To do some of the movements, a pilot has to bear about three times their body weight pressing down on them,” said Wei. They also use special equipment like a spinning ladder to overcome dizziness.
Despite all the training, becoming a top PLA Air Force pilot remains a tough job. “During flight, pilots must carefully decide how to land, especially at night, and maintain position during formation flight,” explained Wei. He added that the key to these skills lies in continuous practice.
In the world of aviation, a balanced mentality and quick thinking are very important. One of Wei’s most unforgettable experiences was dealing with illusions during a formation flight up above the clouds. All he could see in front of him was the lead aircraft and clouds. “I felt like I was turning all the time, but my instruments showed that my flight was level,” said Wei. “In such situations, trusting instruments is essential to making sound decisions.”
But what always remains constant is the great sense of freedom and pride that Wei feels as he flies his aircraft in the sky and looks down at Earth from above. Now, as an experienced flight instructor, Wei hopes to channel his passion for aviation into the “training and development of a new generation of skilled pilots.”
