1 . Cows produce much methane (甲烷) the world’s second worst greenhouse gas, as they break down the grass. They are a large source of the greenhouse gases that are driving climate change. Now scientists have shown the pollution from cows can be reduced by adding a little seaweed (海藻) to their food.

Recently, the researchers from the University of California studied 21 cows on a farm for about five months. They taught the cows to get their food from inside a special hood, which allowed the scientists to know the amount of the methane the cows were giving off. They added a small amount of seaweed to the cows’ food.

The consequences were surprisingly good. In some cases, the cows produced 82% less methane. The improvement depended on the kind of food the cows were given. Even the worst-polluting cows produced 33% less methane. Over the five months, the scientists didn’t see any signs that the cows’ stomachs were getting used to the seaweed and starting to produce more methane again. What’s more, the cows that were fed seaweed gained just as much weight as the other cows.

But there are still some big problems with the idea of feeding cows seaweed. For one thing, there’s not enough seaweed to feed all of the cows in the world. So farmers would have to figure out a way to grow lots of seaweed. A bigger problem is that for most of their lives, cows live in the fields, where they eat grass. That means there’s no chance to feed them seaweed every day.

Still, as the study shows, something as simple as feeding cows seaweed can help reduce some of the pollution causing the climate crisis.

2 . Housing officials say that lately they are noticing something different: students seem to lack the will, and the skill, to deal with ordinary conflicts. “We have students who are mad at each other and they text each other in the same room,” says a teacher. “So many of our conflicts are because kids don’t know how to solve a problem by formal discussion.”

And as any pop psychologist will tell you, bottled emotions lead to silent discontent (不满) that can boil over into frustration and anger. At the University of Florida, emotional conflicts occur about once a week, the university’s director of housing education says, “Over the past five years, roommate conflicts have increased. The students don’t have the person-to-person discussions and they don’t know how to handle them.” The problem is most dramatic among freshmen; housing professionals say they see improvement as students move toward graduation, but some never seem to improve, and they worry about how such students will deal with conflicts after college.

Administrators guess that reliance on cell phones and the Internet may have made it easier for young people to avoid uncomfortable encounters. Why express anger in person when you can vent (发泄) in a text? “Things are posted on someone’s wall on Facebook like: Oh, my roommate kept me up all night studying,” says Dana Pysz, an assistant director at the University of California, Los Angeles. “It’s a different way to express their conflict to each other, consequently creating even more conflicts as complaints go public.” In recent focus groups at North Carolina State University, dorm residents said they would not even deal with noisy neighbors on their floor.

Administrators point to parents who have fixed their children’s problems in their entire lives. Now in college, the children lack the skills to attend to even modest conflicts. Some parents continue to interfere (干涉) on campus.

6 . Chinese traditional painting and dance are two vital parts of the art world. But what about when they meet each other?

This year, a dance drama titled Poetic Dance: The Journey of a Legendary Landscape Painting (《只此青绿》) was staged on CCTV’ Spring Festival Gala and went viral.

According to CCTV, this poetic dance programme was inspired by the about 900-year-old Chinese painting A Panorama of Rivers and Mountains(《千里江山图》). Created by Song Dynasty painter Wang Ximeng at the age of 18, the painting is amazing in its marvellous size, rich coloration and the expressive details, reported CCTV. It shows a Chinese blue-green landscape: mountains and groupings of infinite rise and fall between cloudless sky and rippling water.

When the dancers moved elegantly, audiences seemed to be looking at the moving mountains and rivers. “It brings me a pure experience of beauty. It is not only dance but also an ‘exhibition’. Vast mountains and rivers are coming to life!” An Internet user Mo Weisha wrote in a review, “About a thousand years later, green mountains and rivers still wow people as they did long ago.

Some people even decided to watch the dance again when it was staged in the theaters later. In fact, in recent years, more and more modern shows highlight Chinese traditional culture and have received warm welcome. As for why, it is due to people’s great love for traditional culture.

“The younger generations have grown up with a more open mindset. They embrace Chinese culture and are proud of it. ”Yao Wei, director of Henan TV Station’s Innovation Center, told China Daily.
