On the Sample Materials of Sci-tech Newspaper Manuscript

Science and technology are gradually produced and perfected with the development of human beings, and the development of science and technology further enhances human practical ability. Making scientific manuscripts will help you understand more scientific knowledge. The following is what I brought you for your reference.

1. Why does the hair turn white when people get old?

There is a substance called melanin in our hair. The more melanin, the darker our hair will be. Without melanin, hair will turn yellow or white. When human beings reach old age, various functions of the body will gradually decline, and the formation of pigments will be less and less, so the hair will gradually turn white!

2. Why do fireflies glow?

Fireflies emit light because there is a luminous body at the end of their abdomen, which is filled with a lot of phosphorus-containing luminescent substances and luminescent enzymes, so that fireflies can emit flashing light. The purpose of fireflies is not only lighting, but also courtship, vigilance and trapping. This is also a communication tool for them. Different kinds of fireflies emit light in different ways, frequencies and colors, so they can convey different information.

3. Why do you growl when you are hungry?

When you are hungry, you will purr. This is because the food you have eaten before has almost been digested. Although the stomach is empty, the gastric juice in the stomach will continue to secrete. At this time, the contraction of the stomach will gradually expand, and the liquid and gas inside will be stirred up and purr. Don't be embarrassed by your stomach growling next time! Because this is a normal physiological action.

4. Why can't ostriches fly?

A giant ostrich, but they can't fly into the sky! This is not because their wings are useless, but because their feathers are too soft and their wings are too small to fly at all. In addition, the ostrich's muscles are underdeveloped and its sternum is flat, which is not conducive to flying. Ostriches live in Africa. Because they have lived in desert areas for a long time, their bodies gradually evolved into what they are now in order to adapt to the environment.

5. Why can't the food in cans go bad easily?

Lunch meat, black beans and ketchup beans are all delicious canned foods, which can be preserved for a long time and are not easy to deteriorate. This is because the can is sealed, so bacteria can't enter. When people make canned food, they pump all the air out of the canned food and then seal it. In the absence of air, even if the food inside is contaminated with a little bacteria, they can't survive or reproduce!

Second, science fiction stories.

Scientists are going to let all the people on the earth emigrate, because the earth is too dirty to stay. Scientists started the space shuttles and spaceships of various countries, carrying more than 8 billion people and heading for the new earth at the fastest speed.

At the destination, the new earth is exactly the same as the original clean and beautiful earth. In order to distinguish, humans named this new planet the celestial sphere, and they began to live and reproduce happily. However, less than a hundred years later, human beings treated the celestial sphere like the earth: killing precious and protected animals and deforestation; Numerous pesticide plant, power plants and cement factories have been built ... These factories have discharged a lot of sewage and waste gas, and the ozone layer on the celestial sphere is becoming thinner and thinner. In addition, the frequent activities of sunspots have caused large-scale destruction of the ozone layer. Clear rivers become turbid, green forests become vast deserts, glaciers in the Arctic melt faster, and at least one low-lying country is submerged by seawater every year.

At this time, mankind woke up, but it was too late. No matter what means scientists use, it is of no help. It seems that the situation has reached an irreversible point. Some guys don't care, they think the celestial sphere is dirty, and it's a big deal to live on another planet. Sadly, however, there are only two earths in the whole universe, and not all planets are suitable for human survival.

Fifty years later, the celestial sphere destroyed by human beings suddenly exploded, and human beings died.
