3 . Hans is a young German born after 1995, who is a big fan of Chinese culture. He has been learning traditional Chinese medicine (TCM) since 2016. Now he is studying for his master’s degree at Henan University of Chinese Medicine.
Hans came to Central China’s Henan Province in 2015, where a rich TCM culture can be enjoyed because Henan Province is the hometown of Zhang Zhongjing, the medical master of ancient China. After one year of learning the Chinese language, he started to learn Chinese medicine.
Without a language barrier, Hans read some of the ancient Chinese medical classics, such as Huangdi Neijing and Yi Jing. He believes different aspects of traditional Chinese culture interact with each other.
Studying TCM also changed Hans’ mind and lifestyle. He used to be addicted to electronic devices and stay up late every night, trapped in this fast-paced but unhealthy daily routine. But now, according to the Yin-Yang theory in TCM, he lives a balanced and peaceful life, practicing good habits as well as reading ancient books.
He plans to run a traditional Chinese clinic in China or Germany after graduation, which could serve as a bridge between the two countries and publicize TCM and its culture.

4 . At this very moment around the world, athletes are stepping almost naked into freezing cold rooms. Why on earth are they doing this? Because it’s supposed to help them feel better.
The treatment is called whole-body cryotherapy (冷冻疗法). Basketball star LeBron James, soccer great Cristiano Ronaldo, and boxing champion Floyd Mayweather Jr. have all tried it. The therapy works like this. You take off everything but your underwear. Then you put on warm socks and gloves and step into a small room that looks sort of like a shower, except your head sticking 16% out the top. Once you’re locked in, air cooled to below -200°F (-129°C) fills the room. That’s way colder than Antarctica (南极洲). You stay in for two to three minutes.
Supporters believe the extremely cold air helps muscles recover faster and reduces other body pain. After his first cryotherapy sessions, Phil Mackenzie, a professional rugby player, felt noticeably better. He told Scientific American, “I felt refreshed right away. My sleep was better.” Soon, he was using it four times a week. Those who promote cryotherapy make all sorts of wild claims about its benefits. Supposedly, that extremely cold air can increase focus, improve skin tone, make you happier, burn calories, slow aging, and much more.
Is there any evidence to back up these incredible claims? Nope. Several small scientific studies have looked at whether the therapy can improve muscle recovery after exercise, with encouraging results. But there just isn’t enough evidence to show that the therapy works. The benefits some people experience may just be the placebo effect. That’s when a patient’s expectation that a treatment will work leads to an improvement.
The US Food & Drug Administration has actually issued a warning about whole-body cryotherapy. It cautions that the liquid nitrogen (氮) used to cool the room may make it difficult to breathe. Frost bite is another potential risk, which is why participants wear gloves and socks.
What do you think? Is it a chance for a better athletic performance worth the risk?

5 . For years, doctors have given blood to patients who need it to survive. These transfusions (输血) usually include giving red blood cells to patients.
Blood transfusions aren’t as simple as taking blood from one person and giving it to someone else. There’re several different blood types that don’t all mix well. If someone gets a transfusion of the wrong kind of blood, their body will reject the blood cells, causing problems. For the first time ever, scientists from the University of Bristol, Britain, are carrying out a new trail: testing red blood cells grown in a laboratory on human volunteers. The scientists have used stem cells (干细胞) from a blood sample to grow billions of brand new red blood cells.
This could be even better than a regular blood transfusion. For one thing they can be adjusted for people with different blood types. That’ll be extremely helpful for people with rare blood types. Also, a normal transfusion has red blood cells of all different ages, which means only a small part of them are brand new. The red blood cells grown in the lab are brand new, and this means they last longer and that patients will need fewer transfusions.
To test its safety, researchers have given a couple of teaspoons of the blood to two healthy people, both of whom seem to be doing just fine after the transfusions. In all, they’ll be tested on 10 people, and compared to normal transfusions. The new process doesn’t indicate that normal blood transfusions will disappear. Meanwhile, growing red blood cells in a lab is extremely expensive. And a lot of work and testing still need to be done. But if it’s successful, the process could make life much easier for patients who often need transfusions-even those with rare blood types.

7 . It’s been well over a year since COVID-19 first appeared. Although the virus continues to be a problem in many parts of the world, things are starting to turn back in our favor with the help of vaccines (疫苗).
Vaccine development started in February 2020, when it became clear to scientists that a solution to the pandemic would need a global effort to vaccinate as many people as possible. Of course, this would take great effort, since vaccines typically take years to develop. However, COVID-19 needed faster development. The first COVID vaccine — the Pfizer vaccine — was approved by UK health authorities on Dee 2, 2020.
However, these vaccines must be stored at very low temperatures, which is not possible everywhere. In response, Chinese companies like Sinopharm and Sinovac have developed vaccines using dead viruses instead of spike proteins. These vaccines can be kept at regular temperatures.
As it stands now, vaccines are being rolled out all over the world, with millions of people being vaccinated every day. In China, as of May 4, 285 million vaccine doses (剂量) had been given so far. Meanwhile, the US has given out 247 million doses, according to Our World In Data. The UK now stands at 50 million doses.
Although there have been rumors about vaccines being unsafe, the majority of people seem to realize the importance of vaccination for building mass immunity (大规模免疫) in order to stop the virus from spreading.
Zhang Wenhong, China’s leading expert on infectious diseases, said it’s good that the world has come to understand that the vaccines will protect us. Zhang added that human beings belong to one family. Vaccines are a kind of medicine that we all must share in order to stay safe and healthy.
