 Random interesting fact from the Great Encyclopedia:

What did the inhabitants of the Earth fear in 1910, when our planet passed through the tail of Halley's comet?

In 1910, the Earth passed through the tail of Halley's comet, one of whose components is the poisonous cyanide gas. One of the leading astronomers of the time, Camille Flammarion, predicted in advance that this gas would poison the atmosphere and could kill all life on the planet. In this regard, the population intensively bought protective masks, as well as anti-cyanide pills and umbrellas produced by enterprising manufacturers. As a result, it turned out that the poisonous gas in the tail of the comet was very rarefied and had no effect on living beings.

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 ... >>

Christmas decorations make us happier 01.01.2023

According to psychologists, Christmas decorations in the house increase the level of dopamine, the feel-good hormone.

What makes us happier? First of all, due to the bright lights and colors of New Year's garlands. Chromotherapy, or color therapy, increases energy levels and improves mood. After conducting a series of studies, scientists were able to prove that different colors have their own individual characteristics that favorably affect the nervous system, the internal functioning of the body and the human psyche.

The nostalgia factor is also important. For many of us, the New Year is a family holiday filled with home comfort and a magical atmosphere, this is the time when many wishes can come true. Preparing for the celebration, we are immersed in warm memories, which undoubtedly improves our mood.

However, if you didn’t have warm moments in the past associated with the New Year, psychologists recommend starting new traditions for yourself - whether it’s going out of town, watching themed films with family and friends, or going for a walk, taking an ice cube with you. And what, adults also sometimes want to feel like children!

Another point - if you have New Year's garlands or holiday stickers and drawings on your windows, the neighbors will think that you are a friendly person! Studies have shown that people interpret Christmas decorations in a house as a signal that the residents of that apartment are sociable.

Thus, if you already want to get Christmas decorations, garlands and tinsel from the far shelves of cabinets, do not deny yourself anything!
