Why is there mucus in the nose?

When it comes to the human body, you can be sure that everything that is there has some purpose. This also applies to the nasal mucosa. The nose is the passage through which air enters the body. But before this air enters the lungs, it must undergo some processing. It must be warmed up and cleaned. A significant part of the dust particles that enter with the air is removed with the help of the nose.

Primary air purification occurs with the help of bristly hairs located at the entrance to the nose. Here the coarsest dust particles are filtered out. Starting from the nose and ending with the entrance to the lungs, the airways are covered with cells with tiny hairs growing from them. These hairs are called cilia.

The mucus in our nose is completely transparent. The reason it turns gray-green is because the cilia carry tiny dust particles up the airways into the nose, where they mix with the mucus.

Every minute, day and night, a person inhales millions of dust particles, regardless of where you live. Only over the ocean, no less than 600 miles from the coast, is the air completely free of dust. Even when we breathe clean country air, we get at least half a million dust particles with it!

All sorts of bacteria get into our noses along with dust when we breathe. These bacteria stick to the lining of our nose. And since mucus is an antiseptic, it kills many bacteria. So, you have seen that the mucus in our nose performs very important tasks in protecting our health!

Which jellyfish are theoretically immortal?

Simplified, the life cycle of a jellyfish can be represented as follows: they are born in the form of polyps, then they pass into the medusoid stage, and then adult jellyfish usually die after reproduction. However, there is a unique species of Turritopsis nutricula, whose jellyfish, after breeding, reverse their life cycle and turn back into polyps, in order to then again develop into a jellyfish. Thus, these jellyfish are theoretically immortal (they only die from external causes).

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 ... >>

Improved computer speech recognition 03.06.2017

In the near future, we will be able to communicate with computers and mobile devices as easily and naturally as with people.

Mary Meeker, speaking at the Code Conference event, said that Google has increased the accuracy of English speech recognition to 95%.

Thanks to machine learning algorithms, the Google search engine and voice assistant now understand English speech with the same accuracy as native speakers.

It is worth noting that four years ago, the accuracy of English recognition was 75%.

Given the pace at which Google is developing this area, in the near future we will be able to communicate with computers and mobile devices as easily and naturally as with people.
