【推荐2】Yu Zeling, an award-winning master of paper cutting, fills her studio with cutouts of animals, people, and scenes that are so vivid that they seem to leap from the walls. Her art covers village life in Ansai, a rural district in Shaanxi Province.

Ms. Yu came to paper cutting in the late 1970s as naturally as she breathed the earthy air.“We were very poor, and when it was time to celebrate the New Year, we all put paper-cuts on the windows to decorate our houses,” she says, recalling the holiday at her childhood home. Ms. Yu and others are working to keep the folk art alive, even as it evolves away from its roots as adornment for farmhouses.

The art originated in China in the centuries after paper was invented in A.D.105. Full of auspicious (吉利的) symbols from daily life, the decorations represented good weather, many offspring, long life, wealth, and happiness.

Using newspaper, Ms. Yu first practiced cutting the image of a Chinese national flag that she saw in a school textbook. She cut it 100 times before she was satisfied. Then her aunt took over, introducing her to increasingly complicated traditional themes.

Ms. Yu was later invited to train in the Ansai's Cultural Center. After years of training,Ms.Yu became a master in her own right, winning one award after another. Her works are on display in museums. But she's humble about her achievements. “I was, and still am, a farmer,” she says with a smile.

Hoping to carry on and grow the folk art, Ms. Yu volunteers to teach at free community training sessions. Paper cutting is also taught in Ansai’s public schools. Ms. Yu is aware of the need to go beyond protecting traditions and embrace new paper-cut experiments.

Many doctors predict more vaccines will be out in five years. They are not traditional vaccines that prevent diseases. Instead, they are shot s to shrink tumors(肿瘤 ) and stop the cancer from coming back. Targets for these experimental treatments include breast, 1mg。melanoma(黑素瘤), etc.                       ^

More than ever, scientists understand how cancer hides from the body’s immune system(免疫系统). Cancer vaccines, like other immune system treatments, strengthen the immune system to find and kill cancer cells. Some new cancer vaccines use mRNA, which was developed for cancer. For a vaccine to work, it needs to teach the immune system’s T cells to recognize cancer to be dangerous. Once trained, T cells can travel anywhere in the body to hunt down danger.

Drug producers Moderna is developing an mRNA vaccine tailored for patients with melanoma. Compared with other melanoma vaccines, Modema’s vaccines are designed for each patient, based on the many differences in their cancer tissue, which can train the immune system to hunt for the cancer cells and kill them.

The vaccines under development at the University of Washington are designed to work for many patients. Tests are ongoing in early and advanced breast and lung cancer. Some results may come as soon as next year. Jamie Crase was one of the first people to receive the lung cancer vaccine. Crase was diagnosed with advanced lung cancer at age 34. She thought she would die young. Now she is 50, with no sign of cancer. She does not know for sure if the vaccine helped. But she said, “I’m still here.”
