Why do birds sing?

The bird songs and calls we hear in the spring are part of their love games before mating. Males sing to attract the attention of females. When the male and female find each other, he begins to ruffle her feathers and sing even louder. Females of some breeds of birds answer the male with their songs.

Not all birds are songbirds. There are some, like the stork and the pelican, that seem to have no voice at all. The vocal organs of birds are slightly different from ours. In humans, the vocal cords are located in the larynx, at the top of the windpipe. The simple membrane of birds is located at the bottom of the windpipe, in a part of the body called the lower larynx. This membrane vibrates.

The reason that different breeds of birds sing differently from others lies precisely in the shape of the lower larynx, in the number of muscles that set the membrane in motion. Birds make other sounds besides singing. They exchange cries, signals, disturbing sounds, while understanding each other. If a snake appears near the nest, the bird resorts to an alarm signal. At this signal, flocks of birds flock to her for help.

Birds use various signals and sounds all year round, and they sing only during the nesting period. Bird singing differs in pitch, rhythm, quality. The thrushes are recognized as the leaders in the creation of "real" songs.

Are earthworms good?

Earthworms are a must. Feeding on plant residues, these animals enrich the soil, thus participating in the formation of humus, the minks of worms contribute to the supply of oxygen to the roots of plants. One earthworm can process up to 12 tons of soil per year.

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 ... >>

Bioink for 3D printing of human tissues 13.02.2020

Bioengineers from Rutgers University (USA) have developed "bioink" for 3D printing of materials that could serve as a scaffold for growing human tissues. Printed fabrics can repair or replace damaged human tissues.

In the new system, hyaluronic acid and polyethylene glycol serve as the main "ink cartridges" for 3D printing. Hyaluronic acid, a natural molecule found in many body tissues, has properties that are ideal for creating custom tissue scaffolding, but it lacks the necessary strength. So engineers at Rutgers University used modified versions of hyaluronic acid and polyethylene glycol to make a gel that is strengthened by chemical reactions and acts as a scaffold for tissue growth.

In the future, the new system will have other "ink cartridges" with various cells and ligands, which serve as binding elements for tissue cells. The system will print gel scaffolds with the right stiffness, cells and ligands, depending on the type of tissue to be obtained.
