Why is the ratio of newborn boys to girls so much higher than the norm in China?

For over 30 years, China had a "one family, one child" policy, which meant it was legally forbidden to have more than one child (although permission could be obtained for money). This policy made it possible to significantly reduce the birth rate, but at the same time led to a skew in the ratio of newborn boys and girls. In Asia, boys are traditionally valued more, because they will support their parents in old age, therefore, in the face of a limited number of children, many seek to acquire a boy. By the beginning of the 21st century, 117 boys per 100 girls were born in China at a normal ratio of 105:100, which promises future problems with finding a wife for millions of Chinese men. Since 2016, the government has relaxed the restriction, allowing families to have two children.

Random interesting fact from the Great Encyclopedia:

How did the German physicist Helmholtz assess the degree of perfection of the human eye?

For all its perfection, the human eye is still not without flaws. The German physicist Hermann Ludwig Ferdinand Helmholtz (1821-1894), who studied the optics of the eye, once said: "If an optical workshop had sent me such an instrument, I would have returned it for alteration."

One of the shortcomings of the human eye is the following. The human eye, like the eyes of many animals, belongs to the so-called inverted (reversed) type: the optic nerve is connected to the light-sensitive cells of the retina not from behind, but from above. This allows the retina to detach from the wall of the eyeball, resulting in loss of vision. If the endings of the optic nerve join behind, from the side of the wall, this will strengthen the light-sensitive layer of the retina.

This is how the eye of the squid works, and no one has ever seen a squid with a retinal detachment.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Artificial glacier against global warming 03.05.2017

American scientists have proposed to fight global warming by growing artificial glaciers and thus stop negative trends in the environment.

During the construction of a man-made glacier, artificial snow will be used. According to scientists, to protect the artificial block from exposure to sunlight, you need a layer of several centimeters of such snow. The glacier is expected to grow within 20 years and reach a height of about 800 meters.

In case of successful implementation of this project, such glaciers are planned to be grown all over the world. At the same time, the bright dreams of American scientists are not shared by some economists who believe that the project will cost a fabulous amount. But apparently such a payment will have to be made to humanity for climate change on Earth.
