What is pain?

Have you ever wished you didn't feel pain? In fact, we should thank fate that we have such an opportunity. Pain is our safety net. If you did not feel a toothache, you would not take care of their treatment in time. Without feeling pain when touching something hot, you can cause very serious damage to yourself.

Did you know that there is a disease in which a person does not feel pain? Such people very often harm themselves - by burning themselves, pricking, injuring themselves, because pain does not warn them that they need to be more careful.

Strangely enough, science still cannot fully explain the origin of pain. It is assumed that it owes its appearance to damage to the free nerve endings of the skin. Very weak impact does not cause pain. In other words, these nerve endings feel something, but the pain is only caused by strong energy. In very hot objects, the molecules move at great speed, and therefore, touching them, we feel pain.

The body does not have special pain receptors, but there are special nerves that perceive irritation. They lead through the spinal cord to the head.

The places on the skin where pain is felt when stimulated are called pain points. They are unevenly distributed throughout the body, and in some places they do not exist at all. But on average, there is one pain point on each part of the body the size of the letter "o". Thus, there are about 3 million points on the skin where pain can be felt.

The pain is different - from a burn, a cut, a bite, and so on. Pain is a combination of sensations such as pressure, heat, and others.

How did the Grand Duke of Kyiv Vladimir Svyatoslavovich motivate his rejection of Judaism?

According to the testimony of the chronicler, when asked by Prince Vladimir about where their land was, the Jews who came to convert him to their faith answered: "In Jerusalem." Apparently, the prince knew the history of the Jewish people quite well, since he immediately asked: "Is it really there?" The Jewish preachers were forced to confess: "God was angry with our fathers and scattered us over the countries for our sins, and our land was delivered to the Christians."

Then Vladimir Svyatoslavovich indignantly declared: “How can you teach others, but you yourself are rejected from God and scattered. If God loved you and your law, you would not be scattered over foreign lands. Or do you want the same for us?”

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 ... >>

Carbon emissions turned to stone 16.06.2016

Scientists and engineers from Columbia University (USA) used the example of the Hellisheidi power plant in Iceland for the first time to show that carbon dioxide emissions can be quickly mineralized in months. This achievement will help solve the problem of safe storage of greenhouse gases. The details are published in the journal Science, the results are summarized on the website of Columbia University.

Hellisheidi is the largest geothermal power plant in the world, located in Iceland, powered by hot springs of volcanic origin. Hellisheidi supplies electricity to the capital Reykjavik and the country's industry. At the same time, the process of generating electricity is not very environmentally friendly, resulting in waste in the form of volcanic gases, including carbon dioxide and hydrogen sulfide.

As part of the Carbfix pilot project, which started in 2012 at Hellisheidi, the gases were mixed with water and injected into the basalt rock beneath the power plant. In nature, this mixture in basalt sets off a series of chemical reactions that precipitate carbon as a chalk-like mineral. This is where the idea to apply this process to CO2 storage came from. According to calculations, under natural conditions, the process of deposition takes hundreds and thousands of years.

It turned out that it can be accelerated. In the basalts below Hellisheidi, 95% of the injected carbon solidified in less than two years. "This means that we can pump a large enough amount of CO2 into the depths and bury it quickly in a very reliable way," co-author Martin Stute, a hydrologist at the Lamont-Doherty Earth Observatory (USA), was quoted by the Columbia University press service. In the future, we will be able to use this method in power plants in places where there are large deposits of basalt." And there are many such places on Earth, almost the entire ocean floor is composed of basalts.
