1 . Scientists are now digging into precisely why exercise holds so many benefits for our mental health and memory. The answer, studies say, lies in our brain chemistry.
Each time you work up a sweat, your body releases feel-good happy hormones (荷尔蒙), including endorphins, dopamine and endocannabinoids, the latter being responsible for the so-called runner’s high. Now researchers are also pointing to myokines (肌肉因子) as an important contributor to the mental health benefits of exercise. When our muscles contract, myokines are released into the bloodstream, helping your muscles and organs communicate. They think this communication increases resilience to stress, reduces symptoms of mental suffering and anxiety and has a direct effect on depression.
A 2021 scientific report published in Neuropharmacology showed evidence that myokines boost brain function, like improving memory and mood. “Myokines reduce systemic inflammation (炎症), which is especially beneficial for people with drug-resistant depression whose low mood is linked to high inflammation,” explains Dr Jennifer Heisz, an expert in brain health and associate professor in the department of kinesiology at McMaster University in Canada.
A recent study published in the British Journal of Sports Medicine showed that treatment for depression can be much more effective when physical activity is added to the usual care. Participants found benefits after 12 weeks of exercising for 30 to 60 minutes a day. “While exercise is not a replacement for professional mental health treatment, physical activity can complement and enhance the effects of the treatment,” says lead researcher Ben Singh, a research fellow at the University of South Australia.
“It is amazing to consider how moving our bodies can heal our minds,” says Heisz. Whether you’re cycling, walking around your neighbourhood or doing yoga, getting sweaty is good for your body and mind. To get the biggest overall health boost, the key is to zero in on sports and activities you enjoy, so you’ll keep going back to them.

2 . The maleo (塚雉), a bird with black feathers and a pink chest, is native to Indonesia’s Sulawesi island and a few neighboring ones. The International Union for Conservation of Nature (IUCN), which identifies wildlife across the world currently facing threats, estimates only 800 to 1,400 adult maleos remain in the wild. Experts do not know how many maleos still live across West Sulawesi island. They were only able to record the presence of nesting grounds in 23 villages based on reports from locals in the area. But of those, only 18 are considered active nesting areas.
Recently, the birds have been faced with new threats, which accelerate their decline. The Indonesian government plans to move the nation’s capital from Jakarta to a new city on Borneo island, which is just a six-hour boat trip apart from Sulawesi island. The island takes on the building of new roads and seaports to be used to transport materials to the new capital. Activities also include tree clearing, digging, and removing stones. The process already has changed the forest environment on West Sulawesi and is harming maleo nesting areas near the beach. These changes have made the trip for maleos to lay their eggs increasingly difficult.
Another problem has been poachers. The Associated Press reports that, regardless of official ban, they steal maleo eggs that the males’ parents have hidden in the sand, and sell the eggs for about $1 to people as food. The eggs are a traditional gift for many people in Mamuju and other parts of Sulawesi.
“As far as I know, maleo birds are in decline,” said Andi Aco Takdir, chief of the West Sulawesi Forestry Agency. He pointed to several reasons for the decline, including destruction of beach areas, and expanding human development activities. He added that government officials there are prepared to take steps to protect the maleos even with the new capital development. Andi said, “Nature conservation must be used as an achievement and must not be built leaving behind problems.”

3 . Accompanied by the rhythmic sound of bamboo strips(竹板), Yang Ziqi, 17, from Xi’an Qujiang No l High School, listens to interesting stories in the Shaanxi dialect. The stories range in subject greatly from the story of the Monkey King to instructions on garbage sorting.
“Shaanxi kuaiban is amazing. It can not only bring you great joy, but also broaden your horizons” said Yang. Shaanxi kuaiban is a traditional Chinese form of storytelling in the Shaanxi dialect to the rhythm of bamboo clappers. In June, it was recognized as an intangible cultural heritage at the national level. It can be performed by a group or solo. The art form can be traced back to the late Qing Dynasty (1644-1911). According to its performers, the art was originally used by farmers to share their knowledge and earn money. But now, more people perform Shaanxi kuaiban on different occasions-for example, at festival celebrations, parties and art shows.
Yang Jinlong, 45, is an experienced Shaanxi kuaiban artist. He first learned the art at the age of 9. Before that, he often went with his father, an amateur performer, to watch kuaiban performances.
“As a young boy, I was attracted to the art form because many of the stories are about heroes. The performer tells stories while playing kuaiban, and it’s easy for the audience to remember the stories since all the lines rhyme,” Yang said. He has practiced Shaanxi kuaiban for more than 30 years. Since 2003, he has been teaching the art form to young people. At 9 am on weekdays, he drives to primary and middle schools in Xi’an and teaches students about Shaanxi kuaiban until about 6 pm. Then, he returns home to prepare classes for the next day. On the weekends, he teaches for six hours each day at art education institutions in Xi’an.
Yang has made some adaptations to the art form to relate more to students. When he tells modern stories, Yang abandons the traditional gown and wears a suit. He also integrates many pop elements like tap dance, ballet, jazz dance and the rhythm of popular music into kuaiban performances. His stories focus on more trendy topics, like stories of heroes who have worked to alleviate poverty(扶贫), as well as the Chinese Olympic team.
“Art education is important for students in China. Just as many students learn to play Western musical instruments like the piano and violin, there are many people learning traditional Chinese folk arts, including Shaanxi kuaiban. They are committed and passionate,” Yang said.

4 . Twenty-five years ago, Florence Griffith Joyner, known as “Flo-Jo” died in her sleep, leaving behind a legacy that combined style and speed in the world of track and field. She was celebrated for her remarkable achievements, particularly during the 1988 Summer Olympics in Seoul, South Korea.
During the Olympic qualifiers in 1988, Flo-Jo broke the 100-meter world record with an amazing time of 10.49 seconds. She continued to amaze the world by breaking the 200-meter world record in the same Olympics, crossing the finish line in 21.34 seconds with her iconic style, including long painted nails and colorful one-legged running suits.
Griffith Joyner’s success extended beyond the track. She won two more gold medals at the Seoul Olympics, in the 100 meters and the 4×100-meter relay events, making her an international star. She landed endorsement (代言) deals in Japan, and appeared in American television shows like “Santa Barbara” and “227”. And there was even had a doll modeled after her by LJN Toys.
However, Flo-Jo’s Olympic achievements were not without controversy. In 1989, former American track athlete Darrell Robinson alleged (指称) that Griffith Joyner provided him with money to purchase growth hormones. She strongly denied these accusations, and despite persistent rumors, she never tested positive for any banned substances during her career.
The International Olympic Committee’s medical commission conducted strict drug testing on Flo-Jo during the 1988 Olympics, and she consistently tested negative. She faced questions about the allegations throughout her career but maintained her innocence.
In 1989, just five months after her great success in Seoul, Griffith Joyner announced her retirement from track, explaining that she couldn’t give her all to training as she used to. She transitioned into motherhood, pursued a career in fashion design, and designed NBA uniforms for the Indiana Pacers in 1990.
Flo-Jo’s legacy endures, as she revolutionized women’s sprinting with her exceptional speed and unique fashion sense. Florence Griffith Joyner remains an iconic figure in the world of sports, remembered for her incredible talent, groundbreaking achievements, and unapologetic style.

6 . With 11 foreign languages under her belt, 68-year-old villager-turned tour guide Xu Xiuzhen has become a celebrity in the town of Yangshuo.
Xu was born in a poor family at the base of Moon Hill. In the late 1970s, Yangshuo became one of the country’s first tourist destinations to welcome foreign visitors after China’s reform and opening up in 1978. “I began to see more foreign faces near Mt. Moon, and locals who spoke some English sold more bottled water than me,” said Xu. “No English, no money.” With the influx of foreign guests in Yangshuo, a large number of villagers sought opportunities to learn English given the booming tourism market. Xu eagerly joined the craze. At that time, she made a living on farming and occasionally sold bottled water to tourists near Mt. Moon.
Over the past 16 years, Xu never stops learning and has taught herself 11 foreign languages, including English, Spanish, Japanese and Korean. But the polyglot farmer’s success has been hard-won. She started learning simple English phrases 16 years ago. “I used Pinyin to memorize the pronunciation of English words, but my strong southern accent made it quite difficult to understand,” said Xu. So, “I turned to foreign visitors for help, and I always appreciate their feedback because they have helped me correct my word choices and pronunciation.”
Not content to simply serve as a tour guide, she now owns a popular restaurant and operates a reputable hotel. Huang Yongzhong, director of Yangshuo’s tourism bureau, said Xu’s success has encouraged many farmers to follow suit. He added that the government supports local tour guides by providing frequent training on the laws and regulations of the tourism industry. Farmers in Yangshuo are passionate, sincere and hard-working, and this spirit will lead to more success stories like that of her, he said.

7 . Fifteen years ago, I took a summer vacation in Lecce in southern Italy. After climbing up a hill for a panoramic (全景的) view of the blue sea, white buildings and green olive trees, I paused to catch my breath and then positioned myself to take the best photo of this panorama.
Unfortunately, just as I took out my camera, a woman approached from behind, and planted herself right in front of my view. Like me, this woman was here to stop, sigh and appreciate the view.
Patient as I was, after about 15 minutes, my camera scanning the sun and reviewing the shot I would eventually take, I grew frustrated. Was it too much to ask her to move so I could take just one picture of the landscape? Sure, I could have asked her, but something prevented me from doing so. She seemed so content in her observation. I didn’t want to mess with that.
Another 15 minutes passed and I grew bored. The woman was still there. I decided to take the photo anyway. And now when I look at it, I think her presence in the photo is what makes the image interesting. The landscape, beautiful on its own, somehow comes to life and breathes because this woman is engaging with it.
This photo, with the unique beauty that unfolded before me and that woman who “ruined” it, now hangs on a wall in my bedroom. What would she think if she knew that her figure is captured (捕捉) and frozen on some stranger’s bedroom wall? A bedroom, after all, is a very private space, in which some woman I don’t even know has been immortalized (使……永存). In some ways, she lives in my house.
Perhaps we all live in each other’s spaces. Perhaps this is what photos are for: to remind us that we all appreciate beauty, that we all share a common desire for pleasure, for connection, for something that is greater than us.
That photo is a reminder, a captured moment, an unspoken conversation between two women, separated only by a thin square of glass.

9 . Nearly two decades ago when the Google Books Project digitized and freely distributed more than 25 million works, book publishers argued that free digital distribution weakens the market for physical books. However, new research from Imke Reimers and Abhishek Nagaraj reveals that the opposite—increased demand for physical books, through online discovery—could be true.
The two researchers focused on a particular part of Google Books’ digitized works: those from Harvard University’s Widener Library, which helped seed the project in its early days. The condition that enabled their experiment: Harvard’s digitization effort only included out-of-copyright works, published before 1923, which were made available to consumers in their entirety. The works from 1923 and later were still copyrighted and not digitized.
The researchers analyzed a total of 37,743 books scanned (扫描) between 2005 and 2009. They looked at sales for the two years before this digitization period and the two years after, and found clear differences in the increased sales between digitized and non-digitized books. Approximately 40% of digitized titles saw a sales increase from 2003-2004 to 2010-2011, compared to less than 20% of titles that were not digitized. The increase in sales was also found to be stronger for less popular books.
“If a book is readily available online, people may decide that it’s a useful book and want to buy it,” Reimers said. “The ‘discovery effect’, which even increased the sales of a digitized author’s non-digitized works, is a strong driver of increased sales. It’s not a huge jump in sales, but it’s still good news for publishers.”
“And book lovers,” Reimers said, “are known for their preference for physical books, as opposed to digital versions, which could also play a role.” She added, “Whenever I talk to people about my research on books, at some point they all say, ‘I just love the feel of a book in my hand.’”

10 . Amphibians are animals that can live both on land and in water. A new global assessment has found that 41% of amphibian species that scientists have studied are threatened with extinction. That’s up from 39% reported in the last assessment in 2004.
The study, published on Wednesday in the journal Nature, found that the loss of habitat from the legal and illegal expansion of farming and ranching (放牧) contributes most to the extinction risk of amphibians worldwide. But a growing percentage of amphibian species are now also pushed to the edge of extinction by novel diseases and climate change, the study found.
Amphibians have distinct life stages that each often require separate habitats, so they can be disturbed by changes in either water or land environments, said University of Texas biologist Michael Ryan, who was not involved in the study. They are also at risk because of their delicate skin. Most amphibians absorb oxygen to breathe through their skin, and so they do not have scales (鳞), feathers or fur to protect them. Chemical pollution, bacteria and fungal (真菌的) infections impact them quickly, as do heightened swings in temperature and dampness levels due to climate change.
For example, frogs are active usually at night. If it’s too hot, they won’t come out even at night because they would lose too much water through their skin, said co-author and researcher Patricia Burrowes. But remaining in sheltered resting places limits frogs’ ability to eat and to produce.
Juan Manuel Guayasamin, a frog biologist at the University San Francisco of Quito, Ecuador, said that advances in technology to track animals and climate variations allowed the new study to use much more precise data than the 2004 assessment. “We have a much better understanding of some risks,” said Guayasamin.
The study identified the greatest concentrations of threatened amphibian species in several biodiversity hot spots, including the Caribbean islands, the tropical Andes, Madagascar and Sri Lanka. Other locations with large numbers of threatened amphibians include Brazil’s Atlantic Forest, southern China and the southeastern United States.
