How do our muscles work?

In our body, there are special cells that make up connective tissue - the tissue that connects all parts of our body together. Not all connective tissue cells can contract or shrink. But in some areas of the body, these cells can shrink to the point where they turn into muscle cells. Wherever muscle cells find their way into the body, they are numerous and bundled together to form individual smooth muscles made up of fibers.

There are a lot of smooth muscles in our body, and they help various organs to function. For example, smooth muscles close and open your eyes, regulate your breathing, and carry out internal functions. With development, smooth muscle fibers are transformed into muscles of a different shape, which are called striated.

The human body consists of 639 muscles. The flesh of the body is the muscles. Muscles are also the red meat that we buy in the store. Muscles come in different sizes and shapes. A medium-sized muscle consists of approximately 10 million, and the entire human body of 6 billion muscle cells! Each of these 6 billion muscle cells is like a ten-cylinder engine.

Cylinders in cells are tiny liquid capsules. When a signal from the brain enters these capsules, the muscles contract. In a fraction of a second, the liquid in the capsules thickens and then liquefies again. This process causes the muscles to move. Without striated muscles, our body would not be able to move.

For example, the muscles that control the process of digestion act independently of our desire. The muscle reaction is very fast. The muscle contracts in 0,1 sec. This is immediately followed by muscle relaxation. These cuts are repeated over and over. They happen so fast that the smooth muscles act continuously!

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 ... >>

The design of the large interplanetary station Psyche is completed 19.07.2020

NASA specialists have successfully completed the design stage of the Psyche automatic interplanetary station, which will explore the metal asteroid of the Main Belt (16) Psyche, and have moved on to the stage of manufacturing all systems and scientific instruments. The launch of the station into space is scheduled for August 2022, and it should arrive at the asteroid in early 2026, according to the NASA website.

The goal of the new interplanetary station Psyche, developed by NASA as part of the Discovery program, was the asteroid (16) Psyche, located in the Main Asteroid Belt. It belongs to the spectral class M and contains a lot of metals such as iron, nickel, gold and platinum. This is one of the heaviest asteroids known today, its mass is approximately 2,41x10^19 kilograms, and its dimensions are 274x231x176 kilometers. It is assumed that Psyche may be the metal core of a protoplanet or its fragment, which was formed as a result of a collision with a large celestial body in the early solar system. Detailed studies of such bodies allow not only to learn more about the mechanisms of formation of planets and cores, but also to help in the development of mining technologies in space.

The launch of the mission is scheduled for August 2022, the station will reach the asteroid with the help of Hall engines using xenon, solar panels will provide electricity to all systems of the device. Psyche is expected to arrive at the asteroid at the end of January 2026, after which it will begin its comprehensive study from orbit using a magnetometer, a multispectral camera, a gamma and neutron spectrometer and a microwave instrument to study the gravitational field of Psyche and its internal structure. An experimental laser communication system DSOC (Deep Space Optical Communications) will be used to transmit data to Earth. The data collected by the station will help map the surface of Psyche, explore its internal structure and composition, understand whether it is indeed the core of a protoplanet, and help reconstruct a picture of its formation and further evolution.

On July 7, 2020, NASA announced the completion of the station design phase, which included the creation of drawings of all elements of the apparatus and its scientific instruments, the manufacture and testing of prototypes and engineering models, and the final verification of the designs of all station systems. Now the specialists will proceed to the stage of creating scientific instruments and subsystems of the station. The start of assembly and testing is scheduled for February 2021, by April 2021 all devices should be delivered to the main clean room of the NASA Jet Propulsion Laboratory, where all work will be carried out.
