1 . Imagine the sound of a dog walking across a tile floor, the “click, click, click” of its claws tapping against the ground. Now, imagine a cat walking across the same floor — the difference is the cat moves in total silence. Cats can fully retract (缩回) their claws, giving them superior ability to remain silence.
But why do cats have retractable claws, whereas dogs do not?
It all comes down to how cats and dogs use their claws. Cats use their claws primarily to attack their target, said Anthony Russell, an evolutionary biologist at the University of Calgary in Alberta, Canada. They use their front claws to grab and hold on to their target and their back claws to cut open the target’s belly.
Cats need to keep their claws sharp to secure that next meal. Extended all the time, their claws would get less sharp as they scrape the ground, much like how a nail file deals with sharp points on a human fingernail.
Dogs, on the other hand, are social hunters. They work in groups to take down larger animals, wearing their target out over longer distances. For dogs, “if you’re hunting a moose or something, you wander along for kilometres and bite it until it is fatigued, and then you all jump on it,” Russell said. “Whereas cats essentially have a short burst, and then it’s over. Either the target gets away, or the target is captured.”
With more hunters working together, it’s less important for dogs to be able to grab and hold onto their target, so they don’t have to keep their claws as sharp. Sheer numbers are enough to give them the advantage.
But dogs’ claws aren’t completely useless. Dogs’ claws help them stand firmly on the earth and change directions quickly — a useful adaptation for pursuing target over long distances.
In nature’s silent dance, cats’ retractable claws are knives for quick attacks, while dogs’ strong claws make them good chasers. Each claw tells a tale of adaptation made to their unique hunting styles.

2 . To show empathy (共情) is to identify with another’s feelings. It is to emotionally put yourself in the place at another. The ability to empathize is directly dependent on your ability to feel your own feelings and identify them.
If you have never felt a certain feeling, it will be hard for you to understand how another person is feeling. If you have never put your hand in a flame, you will not know the pain of fire. If you have not experienced jealousy (妒嫉), you will not understand its power. Reading about a feeling and intellectually knowing about it is very different than actually experiencing it for yourself.
Among those with an equal level of emotional intelligence, the person who has actually experienced the widest range and variety of feelings — the great depths of depression and the heights of fulfillment, for example — is the one who is most able to empathize. On the other hand, when we say that someone “can’t relate to” other people, it is likely because they haven’t experienced, acknowledged or accepted many feelings of their own. Once you have felt discriminated (歧视) against, for example, it is much easier to relate with someone else who has been discriminated against. Our innate emotional intelligence gives us the ability to quickly recall those instances and form associations when we encounter discrimination again. We then can use the “reliving” of those emotions to guide our thinking and actions. This is one of the ways nature slowly evolves towards a higher level of survival.
For this process to work, the first step is that we must be able to experience our own emotions. This means we must be open to them and not distract ourselves from them or try to numb (使麻木) ourselves from our feelings through drugs, alcohol, etc.
Next, we need to become aware of what we are actually feeling—to acknowledge, identify, and accept our feelings. Only then can we empathize with others. That is one reason why it is important to work on your own emotional awareness and sensitivity — in other words, to be “in touch with” your feelings.

4 . A 72-year-old Chinese retired physics professor becomes an Internet celebrity. In her short videos, Wu Yuren often uses everyday objects like eggs and coins as props for her experiments. In one video for example, when explaining cosmic rays in space. she grabbed a broom, ran her hand down the broomstick to the thin brush attached, to illustrate how the energy of the rays gradually weakens and disperses. She also explained rocket launches by blowing up a balloon. These interesting science videos have attracted over 1 million followers, many calling her “science grandma”
It’s said that Grandma Wu writes all her video scripts by herself, and she often works with young team members till late at night, just to plan each shoot down to the last detail. For some physics principles that are hard to present, she would discuss them with other professors to work out something easy for people to understand.
Many youngsters are greatly touched by Grandma Wu’s sense of responsibility and mission to communicate physics ideas to the public, especially teenagers. Meanwhile, her lifestyle, embracing new technologies to maximize her value, inspires people in particular.
In recent years, Chinese short-video sharing platforms saw a rise of such elderly Internet celebrities like science grandma. For example, there’s “Grandpa Amu”, an experienced carpenter who turns ordinary wood into exquisite items without a single nail or a drop of glue. "Shaanxi Old Qiao", or Grandpa Qiao, teaches people to cook Shaanxi’s local cuisines in his videos. These noodles and all are so tempting that even kitchen rookies couldn’t help trying.
With the technology boom and the help of young people, many Chinese seniors are opening up a new digital world, and are communicating with the world better through the web. Plus, all this also shows society’s respect and affection for the elderly.
