6 . Winning the silver medal at the 2023 FIVB Volleyball Nations League in the United States, on Sunday, the Chinese women’s volleyball team enjoyed their best result in the tournament (联赛), with the key to the breakthrough being their unity and never-say-die spirit.

“I just feel that our team is more united than ever,” said Yuan Xinyue, Team China captain. “We support and help each other on the court. This is the most important reason behind our success. All of us should shoulder the responsibility of winning.”

She continued to say, “ We have firm determination, and we will keep moving forward. We cherish the road that we have walked. We will summarize events, and we will keep tackling the problems. We will also try hard and hold onto our dreams and the belief that the Chinese women’s volleyball team can be the best.”

Team China was one step away from gold, but the Turkish women’s team showed greater momentum (势头) in the final beating China 3-1. As the Chinese team only finished sixth at last year’s VNL, the second-place finish was a surprise to Chinese fans.

Sunday’s final attracted huge media attention and generated a series of trending topics on social media. While many joined in heated discussion about the final, many more expressed congratulations on the fast rise of the young women’s team.

“Although the Chinese women’s team wasn’t able to stand on the highest podium (领奖台) at the Volleyball Nations League, they still produced the best possible result by fighting together. Hand in hand, Team China players march forward together,” reported by China Sports Daily. “Team China was not among the favorites to reach the final of the VNL, but the team still managed to pocket a silver medal, which is huge progress compared to last year’s result. They proved all the doubters wrong, and they showed the world what a united team they are.”

7 . Last year, 138,000 San Francisco residents used Airbnb, a popular app designed to connect home renters and travelers. It’s a striking number for a city with a population of about 850,000, and it was enough for Airbnb to win a major victory in local elections, as San Francisco voters struck down (否决) a debatable rule that would have placed time restrictions and other regulations on short-term rental services.

The company of Airbnb fiercely opposed the rule, Proposition F. It also contacted its San Franciscan users with messages urging them to vote against Proposition F.

Most people think of Airbnb as a kind of couch-surfing app. The service works for one-night stays on road trips and longer stays in cities, and it often has more competitive pricing than hotels. It’s a textbook example of the “sharing economy”, but not everyone is a fan.

The app has had unintended consequences in San Francisco. As the San Francisco Chronicle reported last year, a significant amount of renting on Airbnb is not in line with the company’s image. Middle-class families rent a spare room out to help make ends meet. Backers of Proposition F argued that this trend takes spaces off the conventional (传统的), better-regulated (监管更好的) housing market and contributes to rising costs.

San Francisco is in the middle of a long-term, deeply rooted housing crisis that has seen the cost of living explode. Located on a narrow land overlooking the bay, San Francisco simply doesn’t have enough space to accommodate the massive inflow of young, high-salaried tech employees flocking to Silicon Valley. Consequently, the average monthly rent for an apartment is around $4,000.

As the Los Angeles Times reported, some San Francisco residents supported the rule simply because it seemed like a way to check a big corporation. Opponents of Proposition F countered that the housing crisis runs much deeper, and that passing the rule would have discouraged a popular service while doing little to solve the city’s existing problems.

8 . A five-­year-­old dog named Kelsey has been praised as a hero for helping to save the life of her owner who slipped in the snow and broke his neck.

The man, Bob, was alone when he left his farmhouse on New Year’s Eve to collect firewood.Expecting a journey of only several meters, Bob was wearing just long johns (衬裤), a shirt and slippers when he went outside, although the temperature was around －4℃.

After the accident, he was unable to move in the snow. Fortunately, Kelsey came to his assistance.

“I was shouting for help, but my nearest neighbor is about 400 meters away, and it was 10:30 p. m.,” Bob explained. “By the next morning, my voice was gone and I couldn’t yell for help, but Kelsey didn’t stop barking.”

Kelsey’s companion kept him warm by lying on top of him. She licked his face and hands to keep him awake. “Kelsey kept barking but never left my side,” Bob recalled. “I knew I couldn’t give up and that it was my choice to stay alive.”

Bob spent 20 hours in the freezing cold. When he finally lost consciousness, his dog kept barking. Finally, hearing the barking, Bob’s neighbor discovered him at 6:30 p. m. on New Year’s Day and called the emergency services at once. When Bob arrived in hospital, his body temperature was below 21℃. However, doctors were surprised to find that he didn’t have any frostbite (冻疮). They believed it was because of Kelsey’s determination to keep him warm. Dr. Chaim Colen, the doctor who treated Bob, said, “His dog really saved him.He was very fortunate.”

Bob said he was very grateful to both Dr. Colen and his Kelsey. “They saved my life. They are truly heroes!”

9 . For people suffering from depression, there’s an all-natural treatment they should use — getting more exercise. It could help fight depression, even if people have a genetic risk, new research shows.

For the study, researchers collected information from nearly 8,000 people and found those with related genes were more likely to have depression over the next two years after examining them. But that was less likely for people who were more active at the study’s start, even if they had a family history of depression. Higher levels of physical activity helped protect even those with the highest genetic risk of depression.

Both high-intensity (高强度) exercise and low-intensity activities were associated with a reduced risk of depression. Adding four hours of exercise a week could lower the risk of a new episode (一段经历) of depression by 17%, according to the study. “Our findings strongly suggest that, when it comes to depression, being physically active has the potential to remove the added risk of future episodes in individuals who are genetically risky,” said lead author Karmel Choi. “On average, about 35 additional minutes of physical activity each day may help people to reduce their risk and protect against future depression episodes.”

Depression is a common mental illness globally, with more than 264 million people affected. “Depression is so ubiquitous, and that underlines the need for effective approaches that can impact as many people as possible,” Choi said. And mental health and primary care providers can use the findings to advise patients that there’s something meaningful they can do to lower their risk of depression.

10 . What makes people so special? Tool use, self-consciousness, language, and culture are high on the list, but in fact all of these characteristics can be found elsewhere in the animal kingdom. Humans and apes are close relatives, so it is perhaps not surprising that chimpanzees use tools or that gorillas (大猩猩) have a sense of fair play, even rejecting carrots (which they normally accept) when they see their neighbors getting grapes. But the qualities that we often think of as uniquely human exist not just on land, but in the ocean as well.

Among the invertebrates, octopuses (八爪鱼) are known for their intelligence, even exhibiting evidence of playfulness, tool use, and personality. But these skilled predators live alone and consequently lack culture. Dolphins, on the other hand, are large-brained, long-living, social- group-based predators, and it is here that we find the greatest similarity to human-like culture and awareness.

Culture depends on the ability of animals to pass on things they have learned to others. Many animals have culture in this sense, but what sets dolphins apart is what they pass on. Some bottlenose dolphins hold sponges in their mouths that they use as tools to sweep for fish hiding on the ocean floor. This ability is handed down through generations (especially in females), with some families — grandmother, mother, and daughter — all feeding in this highly specialized way.

Another characteristic that dolphins share with humans is their ability to recognize themselves in a mirror. When facing a mirror, most animals behave as though they are interacting with another individual. Even in humans, the ability to recognize that the image in a mirror is oneself does not occur before the age of 18 months. Dolphins not only recognize themselves, but if a black mark is put on the body of a dolphin, it will spend extra time at the mirror to look at the mark.
