In the past year, I had an unforgettable experience of learning tai chi. Honestly speaking, I admitted that I     1     (feel) hesitant at first but with time passing by, it really had a huge effect on me     2     (physical) and mentally. Not only were I deeply impressed by the moves that caught my imagination, such as “white crane spreading its wings” and “golden rooster standing on one leg”, but also I     3     (inspire) to explore Chinese culture.

It is all about keeping a balance between yin and yang,     4     are believed to form the unity of opposites. The practice of taichi aims     5     (maintain) the balance of our body through opposite     6     (movement): up and down, left and right, forwards and backwards, breathing in and breathing out. By performing the routine, tai chi eventually brings     7     a state of physical and mental peace. No wonder it is a best way to relax your mind and body.

I also experienced a short period of tiredness and boredom. Thanks to the patient guidance of professional coach, I gradually found to my     8     (satisfy) that I could focus on peace of mind and sleep better,     9     (enable) me to stay cool under pressure. I am sure I will continue to practice tai chi and enjoy     10     benefits it has brought me.

4 . Ru Ling loves spending time in skywells. To her, these courtyards of old houses are the perfect place to be in on a hot and humid day. From 2014 to 2021, Ru lived in a century-old wood-framed home in the village of eastern China’s Anhui province. She moved there for a change of life after living and working in air-conditioned buildings for many years.

A skywell, or “tian jing”, is a typical feature of a traditional home in southern and eastern China. They are relatively common in historic residences in Sichuan, Jiangsu, Anhui and Jiangxi. In today’s rapidly urbanizing (城市化) China, fewer and fewer people live in skywell dwellings—air-conditioned flats in multi-storeyed buildings and tower blocks are the main forms of homes.

But a revival (复苏) of interest in traditional Chinese architecture is leading some of historic buildings with skywells to be restored for modern times. Meanwhile, as a government push has made low-carbon innovations in the building sector a trend, some architects are drawing inspiration from skywells and other traditional Chinese architectural features to help keep new buildings cooler.

Ancient “green wisdom” such as skywells continues to inspire today’s climate adaptive design and innovations in passive cooling, according to Wang Zhengfeng, a researcher at the Institute for Area Studies at Leiden University in the Netherlands. Passive cooling is a method that incorporates design and technology to cool a building without the use of power.

However, Wang points out some challenges for bringing skywells into modern designs. The mechanisms of courtyards facilitating natural lighting, ventilation and rain collection are well known, but applying these principles needs to be site-specific. Because traditional skywells had different shapes, sizes and features, adding skywells into modern buildings requires designers to be sensitive to their project’s context (环境) and situation, she explains. When asked about why skywells have appealed to modern Chinese people, Wang says that the courtyard is also designed to serve as a gathering space for families or communities. “Perhaps changes in the lifestyle could also lead to nostalgia among people living in concrete and glass forests.”

7 . Heman Bekele, a 14-year-old student from Annandale, Virginia, has created a bar soap (肥皂) to treat melanoma, the most common kind of skin cancer, which earned him the title of America’s Top Young Scientist and a $25,000 cash prize after his innovation won first place in the 3M Young Scientist Challenge.

“I made this soap by mixing regular medicinal soap with different cancer fighting chemicals.” Bekele said in an interview. Rather than a cure, Bekele’s soap aims to help the patient’s immune cells stay active while fighting melanoma.

While similar methods are available for skin cancer treatments, his solution is a more affordable alternative, especially for those in developing countries. Though the product is very promising on paper, studies would have to be carried out to test its efficiency in the real world.

For now, the young scientist said he has a five-year plan: At the end of it, he hopes to have created a nonprofit organization where he can provide fair and accessible skin cancer treatment to as many people as possible. But to accomplish his goal, he would have to get his treatment through clinical trials, obtain a temporary patent and have it licensed by the Food and Drug Administration, he said.

“I applied for the 3M Young Scientist Challenge because I believe that young minds can make a positive impact on the world,” Bekele said. “I have always been interested in biology and technology, and this challenge gave me the perfect platform to showcase my ideas. The opportunity to work with 3M mentors and show my project to judges was an exciting prospect. I am passionate about finding sustainable solutions to global problems, and I hope to inspire others to do the same.”

9 . Despite an ever-higher bar to grab the attention of students in large lecture hall, Tatiana Erukhimova, who teaches physics at Texas A&M University, has managed to get her students, as well as future generations, excited about the science.

Known as “Dr. Tatiana”, the professor performs physics tricks with boundless energy and enthusiasm in her videos. A range of everyday objects are used in her experiments, from pingpong balls and toilet paper to marshmallows, bicycle wheels and hair dryers. Videos of her dramatic demonstrations have received hundreds of millions of views across social media platforms.

However, things aren’t always easy. When she first started teaching college freshman classes two decades ago, she also struggled to grab the attention of her students. “I did not grab their attention on the first day-that was my mistake.” she says. “I missed this opportunity to bond with them from the very beginning, and then it took me a while to find my voice.”

By the second semester, she found her footing, adjusting her approach to get her students engaged. The key, she says, has been to make herself approachable and her instruction personal. And, of course, add showy demonstrations. “These demonstrations often help students to connect these abstract concepts with real life.” she says.

Physics department head Grigory Rogachev says Erukhimova’s work has helped bring visibility to the department, with about 2. 5 million subscribers on its department’s YouTube page, which has translated to a boost in research funds and physics major applicants.

As a leader in a STEM field in which women are underrepresented, she’s become a role model for some. Afiya Dhanani attended Texas A&M University after seeing Erukhimova’s videos online. “Watching Dr. Tatiana do the experiments online, especially since she was a female leader. Was more inspiring for me to even go into physics.” Dhanani said in an interview with CBS Mornings. That’s all Erakhimova says she can hope for -making physics less forbidding and more exciting.
