Some dogs are exceptional. Take Chaser for example, an American border collie (边境牧羊犬) regarded as the “smartest dog in the world”, who could recognize and remember 1, 022 nouns — one for each of her toys. In Germany, another border collie, a male named Rico, practiced “fast-mapping”, or figuring out the names of new things with the speed and cleverness of a three-year-old child.
Yet such examples of dog genius are often “about only one dog”, says Claudia Fugazza, an ethologist who studies dog cognition (认知) at Budapest’s Eotvos Lorand University. She and her colleagues asked owners of 34 pet dogs of various breeds (品种) to teach their dogs names for two separate toys. Out of those 34 animals, only one dog passed the test — a border collie named Oliva. “These results mean talent must be something special,” says Fugazza, lead author of a new study on the experiment.
The scientists looked for dog owners worldwide via social media, then asked them to play fetch with their dogs daily in their homes while repeating the name of the toy, a process that lasted three months. Once a month, with a scientist present, the owners tested the dogs—the study participants included both adults and little dogs — by asking the dogs to fetch one of two toys by name. Dogs that succeeded were then given a new toy and new name to learn. Despite the intensive training, only Oliva learned to match a single word to a toy — in fact, she learned 21 names in two months.
“None of the breeds learned a thing. It was such a surprise,” Fugazza says. To check if the study design worked, the scientists also tested six border collies that could already fetch some toys by name; as predicted, all six of those control dogs, including a dog named Nina, learned additional names.
It’s interesting that 18 of the 33 dogs that failed the test were also border collies, Fugazza points out, showing that the breed isn’t always high performing.
Because of such individual difference, the scientists next plan to track the genetics(基因) and history of a variety of dog breeds to try to identify the factors that produce such smart creatures.

An unforgettable Tech Exploration Tour
The first time I entered the busy Chinese hotpot restaurant, I was immediately impressed by the delicious smells and lively chatter. The waiter handed me a menu, but it was mostly written in Chinese,
As the bubbling pot was set
The moment of truth came
I continued to experiment, trying various ingredients and
If someone asked whether you like the arts, you’d probably say you do—at least in theory. According to a survey, more than two-thirds of U.S. adults say the arts “lift me up beyond everyday experiences.” However, only 30 percent attended a concert of any type in 2017; 23 percent went to an art museum. Fewer than half actively created art of any kind.
The mismatch can boil down to the fact that we are weighed down by our day-to-day responsibilities, leaving our schedule packed. Maybe you like to play a little background music while you work or do the chores, but even before the pandemic, most of us rarely, if ever, saw a live performance, let alone visited a gallery or watched a play.
Too often, we let the dull reality of life get in the way of the arts. But this is a mistake. The arts are the opposite of an escape from reality; they might just be the most realistic glimpse we ever get into the nature and meaning of life. If you make time for consuming and producing art—the same way you make time for work and exercise and family commitments—I assure you that you’ll find your life getting fuller and happier. Think of a time when you heard a piece of music and wanted to cry. Or maybe your dizziness as you emerged from a narrow side street in an unfamiliar city and found yourself in a beautiful town square as if in a fantasy. They probably stimulated a sudden awakening, much like the shock from a lungful of pure oxygen after breathing in smoggy air.
If you are among the people who feel that art is pure pleasure to experience and participate in, you might see it as a luxury item, while a preferable attitude is to treat art less like a distracting pleasure, and more like exercise or sleep, a necessity. Then draw up a schedule of your art exposure journey, and gradually weave art into your everyday life.

The Science of Risk-Seeking
Sometimes we decide that a little unnecessary danger is worth it because when we weigh the risk and the reward, the risk seems worth taking.
The reason why any of us take any risks al all might have to do with early humans. Risk-takers were better at hunting, fighting, or exploring.
So why aren’t we all jumping out of airplanes then? Well, even 200,000 years ago, too much risk-taking could get one killed. A few daring survived, though, along with a few stay-in-the-cave types. As a result, humans developed a range of character types that still exists today. So maybe you love car racing, or maybe you hate it.
No matter where you are on the risk-seeking range, scientists say that your willingness to take risks increases during your teenage years.
