"I spent my whole life doing one thing", Gu Fangzhou once said. Known as "the father of sugar pills (糖丸) ",Gu passed away at age 92 on January 2, 2019. Eight months later, he received a national honorary- title (荣誉称号) "the People's Scientist" for his polio (脊髓灰质炎) research.
Gu Fangzhou, a famous medical scientist, was born in June. 1926. Gu's family faced a difficult time with the sudden death of his father. He studied hard and finally entered Peking University as a medical student in 1944. After graduation, Gu made the decision to work to help improve public health.
In 1955, polio broke out in Nantong. Jiangsu Province. It paralyzed (使瘫痪) 1. 680 people, mostly children aged below seven. It spread to neighboring areas and resulted in 466 deaths. Gu was asked to lead polio research in 1957. "At that time the only way to prevent polio was to invent a vaccine (疫苗) , " said Gu.
In 1959 Gu succeeded in developing the first polio live vaccine. Later, he developed the " sugar - coated pill" vaccine in the early 1960s. It not only tasted better but was more affordable and easier to keep. In order to test the vaccine, Gu himself tried the vaccine and later his one - month - old son was vaccinated. This inspired his team to vaccinate their kids. They became the first group of people in China to try a polio vaccine. "If we don' t believe in what we produce, how can others believe in it?" said Gu.
Gradually, the sugar - coated polio vaccine was made available in China. It saved millions of people, especially kids, from being disabled. In 2000, the World Health Organization (WHO) announced that China was already a polio - free country. "We feel satisfied. I can tell people that I tried my best, and your kids will no longer get polio,” said Gu. “That's all we hoped for. "

China’s biggest solar-powered drone (太阳能无人机), Qimingxing-50 or Morning Star 50, finished its first test flight in September, 2022. The drone was built by the Aviation Industry Corporation of China (AVIC, 中国航空工业集团有限公司).
Drones have been used for quite a few years now. There are different ways of increasing the flying time. However, all these methods become less useful compared with the unlimited (无限的) power provided by the Sun. That’s why researchers have been working to make solar-powered drones that can not only stay in the air for longer but also perform more tasks while in the sky.
In 2018, China tested the first version (版本) of Morning Star, which was 91 feet wide. Made from a special kind of plastic, the drone was so light, weighing only 41 pounds. Compared with it, the Morning Star 50 is much larger and has a wingspan (翼展) of 164 feet.
On September 3, Morning Star 50 took off from an airport in Yulin City in the Shanxi province in northwest China and landed back 26 minutes later after a smooth flight. Staff told some local reporters that all flight systems worked normally. This is a good start for future flights of the solar-powered drone that could last for many days or even months at a time.
In the US, Airbus has been testing the Zephyr solar-powered drones for the past few years. Its latest version, the Zephyr S, came close to breaking the record for the longest flight. It stayed in the air for 64 days. Unluckily, the drone fell onto the ground only a few hours before it would have set a new record.
