What is ringworm?

This is a very common skin disease. It is caused by a fungal infection. Usually this disease manifests itself on the arms and legs. The most common form is one or more round, raised skin sores. They look quite healthy in the middle, while the edges continue to grow. Sometimes the healthy center of the ulcer gets an additional infection, and then another ring appears inside the ring.

In some cases of ringworm, the central part does not heal at all. In the initial stage, ringworm is a small, slightly swollen area of reddish skin. Then it reddens even more, blisters may appear, a slight itching or burning sensation may be felt.

Another common type of ringworm is a scalp condition. It is a highly contagious disease that children can easily contract. The fungi that cause ringworm are very difficult to destroy, so the treatment of the patient usually consists of preventing the spread of the infection until the disease is over. Because ringworm is a highly contagious disease, it can be spread through people and animals. Objects touched by sick people can infect other people.

The disease is best treated if it is detected at an early stage. You need to go to the doctor. He will make sure that ringworm does not spread to other parts of the body, and will help you get rid of this disease as soon as possible.

Random interesting fact from the Great Encyclopedia:

Who are the aborigines?

Indigenous, that is, those who originally lived, the inhabitants of the area are called aborigines. These were the people who stayed in the area until any new settlers arrived from other parts of the world.

The word "aboriginal" comes from the Latin, meaning "from the very beginning." Initially, it was used by Roman writers describing the tribes that originally lived in the territories where Rome developed. The Bushmen are considered the indigenous population of South Africa because they lived there before the Bantu Negro tribes. The primitive tribes of people who inhabited Australia before the arrival of Europeans were called Australian Aborigines.

They are probably the most famous natives in the world. Australian Aborigines lived mainly inland and on the remote northern coast. There are only 160 of them. Their ancestors led a nomadic lifestyle and roamed the forests. Today, only a small proportion of these natives live in this way. Australian Aborigines belong to a specific population group known as the Australoids. It is not known how long ago they appeared in Australia. Until the Europeans began to influence them, they did not wear clothes, did not build permanent dwellings, did not grow crops, and lived like itinerant hunters.

Today, many of them have banded together to fight for their rights in Australia. They have the right to vote in federal elections. They are given all the social benefits available to the rest of the inhabitants of Australia.

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 ... >>

Shared attention synchronizes brains 04.05.2017

It is known that when two people engage in some kind of joint activity, their brain activity is synchronized. When several musicians play the same piece, their brains work in harmony with each other, even if the musicians themselves play different parts. Common features in brain activity can be found in people who just watch movies together.

Researchers from New York University experimented with a group of students: during the semester, students went to class wearing a portable device for reading brain waves. Thus, we managed to collect information about how the brain works in a real, non-laboratory social group and under different conditions: when a person is interested in listening to material, when, on the contrary, it is boring; in addition, the authors of the work were interested in how each of the participants in the experiment relates to their comrades and to the teacher, and how much each of them generally likes group activity.

It turned out that the degree of synchronization of brain activity coincided with how interested students were in the subject and in the teacher - in other words, if they were interested in the material and how it was presented, their brain electrical rhythms became similar. On the other hand, synchronization depended on how much people like each other and how easy it is for them to communicate with each other. That is, in response to interesting material, close friends’ brains coincide more strongly than those who are indifferent to each other (although they may also be interested in class).

Great synchronization between friends came only if they personally talked before the lecture; moreover, at the lecture itself, it was no longer necessary for them to look each other in the face - their brains were synchronized anyway. Everything looked as if two people tuned in to a common wave before the event, so that afterward they perceived the event itself in the same way. Those for whom it was especially important to work in a group showed greater synchronization with their comrades.
