1 . What are scientists?They are often described as gray-haired white-coated dull scholars.
But the world has changed.Young scientists are making their voices heard and releasing their powers on the world stage.
This is also true in China.Rising stars include new materials expert Gong Yongji,university professor Liu Mingzhen,and biologist Wan Ruixue.At the age of 28 in 2018,Wan Ruixue received the 2018 Science & SciLifeLab Prize for Young Scientists.This is a global prize to reward outstanding scientists at an early stage of their careers.
She focuses mainly on biomedicine (生物医学) and artificial intelligence.“Both are cutting-edge (前沿) technologies at an early stage of development,” she said.
“So,I think they have great potential to be developed.I think in the study of cutting-edge technologies,China and other leading countries in the world are standing on the same starting line.And in the study of structural biology,China is likely to become the leader.”
She felt it was her fate to become a biologist.“I grew interested in the natural world,when I was very young,” she said.In 2009,she entered Sun Yat-sen University.
In her third year at the university,she realized that she wanted to do something related to biomedicine.So she emailed China’s top biologist Shi Yigong,hoping to join his lab at Tsinghua University.
Shi recognised her talent and welcomed her.Years of efforts at the lab have paid off.Her research on the high-definition 3D structure of spliceosome led to a scientific breakthrough.
Unlike many of other young scientists who choose to pursue further study abroad,Wan currently has no plan to go overseas.
“The whole ecosystem for scientific research is continually improving in China,” she said,adding that the country has great science facilities.

2 . John von Neumann was the oldest of 3 children of a banker, and his speed of learning new ideas and loving problems stood out early. At 17, his father tried to persuade him not to become a mathematician because he might lead a poor life being a mathematician, so von Neumann agreed to study chemistry as well. In 1926, at 23, he received a degree in chemical engineering and a Ph. D. in mathematics. From then on, mathematics provided well enough for him, and he never had to turn to chemistry.
In 1930, von Neumann visited Princeton University for a year and then became a professor there. His first book was published in 1932. In 1933, the Institute for Advanced Study was formed, and he became one of the 6 full-time people in the School of Mathematics (Einstein was one of the others).
World War Ⅱ hugely changed von Neumann’s areas of interest. Until 1940 he had been a great pure mathematician. During and after the war, he became one of the best mathematicians who put mathematical theories into practice. During the last part of the war, he became interested in computing machines and made several fundamental contributions. After the war, von Neumann continued his work with computers, and was generally very active in government service. He received many awards, was president of the American Mathematical Society and was a member of the Atomic Energy Commission. He died of cancer in 1957.
Von Neumann made several great contributions and any one of them would have been enough to earn him a firm place in history. He will be remembered as one of the greatest minds of the 20th century.
Von Neumann really was a legend in his own time, and there are a number of stories about him. His driving abilities is a part of his legend. He reported one accident this way: “I was driving down the road. The trees on the right were passing me in an orderly fashion at 60 miles per hour. Suddenly one of them stepped in my path.”

4 . Most people know that Marie Curie was the first woman to win the Nobel Prize, and the first person to win it twice. However, few people know that she was also the mother of a Nobel Prize winner.
Born in September, 1897, Irene Curie was the first of the Curies' two daughters. Along with nine other children whose parents were also famous scholars, Irene studied in their own school, and her mother was one of the teachers. She finished her high school education at the College of Sevigne in Paris.
Irene entered the University of Paris in 1914 to prepare for a degree in mathematics and physics. When World War I began, Irene went to help her mother, who was using X-ray facilities (设备) to help save the lives of wounded soldiers. Irene continued the work by developing X-ray facilities in military hospitals in France and Belgium. Her services were recognised in the form of a Military's Medal by the French government.
In 1918, Irene became her mother's assistant at the Curie Institute. In December 1924, Frederic Joliot joined the Institute, and Irene taught him the techniques required for his work. They soon fell in love and were married in 1926. Their daughter Helene was born in 1927 and their son Pierre five years later.
Like her mother, Irene combined family and career. Like her mother, Irene was awarded a Nobel Prize, along with her husband, in 1935. Unfortunately, also like her mother, she developed leukemia because of her work with radioactivity(辐射能). Irene Joliot-Curie died from leukemia on March 17, 1956.

5 . Edmund Halley was an English scientist who lived over 200 years ago. He studied the observations of comets which other scientists had made. The orbit of one particular comet was a very difficult mathematical problem. He could not figure it out. Neither could other scientists who dealt with such problems.
However, Halley had a friend named Newton, who was a brilliant mathematician. Newton thought he had already worked out that problem, but he could not find the papers on which he had done it. He told Halley that the orbit of a comet had the shape of an ellipse.
Now Halley set to work. He figured out the orbits of some of the comets that had been observed by scientists. He made a surprising discovery. The comets that had appeared in the years 1531, 1607, and 1682 all had the same orbit. Yet their appearances had been 75 to 76 years apart.
This seemed very strange to Halley. The different comets followed the same orbit. The more Halley thought about it, the more he thought that there had not been three different comets, as people thought. He decided that they had simply seen the same comet three times. The comet had gone away and had come back again.
It was an astonishing idea! Halley felt certain enough to make a prediction of what comet would happen in the future. He decided that this comet would appear in the year 1758. There were 53 years to go before Halley’s prediction could be tested. In 1758 the comet appeared in the sky. Halley did not see it, for he had died some years before. Ever since then that comet has been called Halley’s comet, in his honor.

8 . What killed King Tut? Historians and scientists have long believed that ancient Egypt’s most famous king was probably murdered. But a recent scientific study claims to have found a different answer to this more than 3,300-year-old mystery. A team of researchers now say that King Tut, the boy ruler, died of complications (并发症) from a broken leg.
Tut’s full name was Tutankhamun. He was just 9 years old when he became the ruler of Egypt in 1333 BC. His treasure-filled tomb was discovered almost a century ago. It was filled with royal riches, including a solid-gold coffin, a gold mask, and piles of jewelry.
Unfortunately Tut died at the age of 19. Many experts have thought that Tut was killed by one of his advisers, named Ay, who wanted to be king. But thanks to a major modern science project, it seems Ay is innocent.
Researchers set out to solve the mystery of King Tut’s death by using the tools of science, including DNA tests and electronic scans of his mummy (木乃伊). Scientist Carsten Pusch carried out the tests on Tut for the new study. He thinks a broken leg led to the young king’s death. More than 100 walking sticks were found in King Tut’s tomb. This supports the team’s findings. But how could a person die from a simple broken leg?
Pusch also found DNA evidence in Tut’s body that shows he had malaria, a disease carried by mosquitoes. Malaria seriously weakens the immune system (免疫系统).
Pusch and his fellow researchers believe the malaria and the bone disease together caused the king’s fracture (骨折) to become deadly. Finally, the young king was just too weak to recover. So effects of the disease combined with the bad luck of a broken bone — not a jealous adviser — are likely the real causes of King Tut’s death.

10 . Jules Verne was born on 8 February 1828 in the French city of Nantes. From an early age, he had a fascination with exploration and discovery. When he was six, his teacher, Madame Sambin, told him stories about her husband, who disappeared while travelling the world on a ship 30 years before. She told her class that he was like Robinson Crusoe, a fictional (虚构的) castaway who lived on a desert island. Verne would later write stories about similar characters.
In 1847, Verne was sent by his family to study law at a university in Paris, but he preferred to write novels, poems and plays. After graduating, he realized he wanted to write science adventure stories. This had never been done before, but Verne was sure that it would be a success. His first story, Five Weeks in a Balloon, was published in September 1862. His career lasted for more than 40 years, during which time he wrote more than 60 gripping (扣人心弦的) stories.
To begin with, Verne wrote positive and optimistic books. Many of these were to be his most popular creations. Although some included fantastical elements, they were usually based on scientific facts, making them believable. These happy stories weren’t to last. As he got older, Verne became less confident in the idea that science and technology were always good for the planet. His books started to include more scientists who used technology for their own—sometimes evil—purposes. Verne died on 24 March 1905, but new books continued to be published until 1919. These stories were based on ideas Verne had written about while he was still alive, but featured new characters and plots created by his son, Michel.
In the 20th century, his books were translated into more than 140 languages and several successful film versions came out. His creations have been recognized as an inspiration for many scientists and inventors. Many of the futuristic ideas from his most popular books have since come true.
