Life is full of surprises and you never know how things will turn out.

Sir John Gurdon is a good example of this. As a boy, he was told he was hopeless at science and finished bottom of his class. Now, aged 79, the very same Gurdon shared the 2012 Nobel Prize in Medicine with Japanese stem cell(干细胞) researcher Shinya Yamanaka.

Like so many scientists, Gurdon shows us where the power of curiosity and perseverance(坚持不懈) can lead.

At the age of 15 in 1948, Gurdon ranked last out of the 250 boys at his high school in biology and every other science subject. Gurdon's high school science teacher even said that his dream of becoming a scientist was "quite ridiculous".

In spite of his teacher's criticisms, Gurdon followed his curiosity and kept working hard. He went to the lab early and left later than anyone else. He experienced thousands of failures.

    "My own belief is that we will, in the end, understand everything about how cells actually work." Gurdon said.

    In 1962, Gurdon took a cell from an adult frog and moved its genetic(基因的) information into an egg cell. The egg cell then grew into a clone(克隆) of the adult frog. This technique later helped to create Dolly the sheep in 1996, the first cloned mammal(哺乳动物) in the world.

    In 2006, Gurdon's work was developed by Yamanaka to show that a sample(样本) of a person's skin can be used to create stem cells. Using this technique, doctors can repair a patient's heart after a heart attack.

    "Luck favors the prepared mind, "Gurdon told the Nobel Prize Organization." Ninety percent of the time things don't work, but when they do, you have to seize(抓住) the chance. "

A grandmother, dressed in hanfu, impressed(使印象深刻) hundreds of thousands of people with her beauty and love for life.

Her grandson Liu Haochen made the first short video and the video received 1.76 million likes on the Internet within a month. Now known as vlogger(视频博主) "Hanfu Grandma" with more than 550,000 fans, she has tried on many different costumes. Liu, also a lover of hanfu, said he wanted to share happy memories with his grandma and to record her life at an old age. And he found she is quite suitable for the clothing.

The grandma said she agreed Liu to shoot a video for her. "I don't really know what it was about at the time. I thought it would be good to spend some time with Chenchen," she said, as Liu had been busy working far from home.

She once took part in a fashion (时尚) show in Changzhou, Jiangsu Province, with performers much younger than her. When the show began, it was raining, but she said she quite enjoyed it. "When I was on the stage, the audience(观众) kept shouting my name. I was very cheerful," she said.

Most of her videos are filmed outdoors, with some at scenic spots in different cities, often with other young hanfu lovers. For her, it's more like travelling than filming. Along with videos about hanfu, she also shares her daily life —shopping, drinking milk tea and playing with cats. She said life has become more interesting compared with before, and she is as energetic as a young person.
