What is hemoglobin?

Most of our blood cells are red blood cells. Millions and millions of red blood cells circulate through the blood vessels. Red blood cells contain a protein called hemoglobin. Hemoglobin is a red pigment containing iron atoms. Our blood is red in color because it contains hemoglobin compounds with oxygen.

Hemoglobin has a more important function for the body than just turning blood red. It has the ability to form an unstable compound with oxygen. This ability allows red blood cells to carry oxygen throughout the body. Oxygen is part of the air passing through the lungs, and hemoglobin picks up oxygen molecules. Continuing their journey through the blood vessels, red cells carry oxygen to all cells of the body.

When an oxygen molecule is delivered to a cell of the human body, hemoglobin takes away a carbon monoxide molecule from it, which was formed there in the process of burning food by this cell. Then the red blood cell, loaded with a molecule of carbon monoxide, returns to the lungs, where an exchange takes place: carbon monoxide is detached and excreted from the body along with the exhaled air, and a new oxygen molecule is picked up in its place. The red blood cell then continues on its way to deliver that oxygen to the appropriate cell. That is why it is very important that our food contains iron. It stimulates the production of red blood cells and increases their hemoglobin content.

How many legs do centipedes have?

The centipede is the household name for various types of arthropods, scientifically united in the superclass centipedes. Different species of centipedes have from 30 to 354 legs, and this number can be different even in individuals of the same species. Moreover, any centipede must have an odd number of pairs of limbs, so there may be 38 or 42, but not 40. In English, two names for these animals are established - centipede ("centipede" in Latin) and millipede ("thousand-foot "). Moreover, the difference between them is significant - centipedes are not dangerous to humans, and centipedes bite very painfully.

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 ... >>

Wheat grown tolerant of salty soil 23.03.2012

A group of Australian scientists, with the participation of the University of Adelaide, has found a way to create various durum wheat varieties that increase grain yields by 25% on saline soils.

Interestingly, the Australians claimed the new wheat varieties were not genetically modified crops, although a special gene was introduced into the wheat genome to confer salt tolerance. Although they used molecular techniques to identify the salt tolerance gene, the scientists said the introduction of the gene was not done by traditional genetic modification methods. This means that products made from such wheat will not be classified as transgenic and can be sold without any restrictions.

For the first time, scientists have managed to introduce a salt-tolerance gene into the wheat genome, and field studies show that the new wheat is not only not sensitive to salty soil, but also yields 20-25% more yield on it.

The development of the Australians is very important, since 20% of agricultural land worldwide already faces the problem of soil salinity. The problem is getting worse every year and poses a great threat to food production, especially in light of global climate change. Soil salinity is a concern in Australia, which is the world's second largest exporter of wheat after the US. According to experts, in 2050 the world population will reach nine billion people, and the demand for food will grow by 100%. Salt-tolerant crops in the future will become the most important tool for ensuring the food security of mankind.
