What do snakes sniff?

Snakes have a very well developed sense of smell. But they sniff, however, not with their nose.

In the mouth of snakes there is a deep paired fossa - Jacobson's organ. The inner surface of this fossa is covered with special sensitive cells. Having stuck out its forked tongue and felt it with an incomprehensible object, or simply waving its tongue in the air, the snake puts the tips of the tongue into the pits, and microscopic particles or even molecules adhering to the tongue are perceived by the Jacobson organ. A strange way to sniff, but quite effective.

Snakes easily crawl along the trail of prey, find traces of relatives, distinguish males from females, old and young, familiar and unfamiliar animals.

Random interesting fact from the Great Encyclopedia:

Where does iron come from to make steel?

Steel is an alloy of iron and carbon. Other substances can be added to give the steel various characteristics: strength, resilience, elasticity. But the main material for steel production is iron. Iron is not usually found in nature in its pure form. Most of it is mined in a mixture with other substances in the composition of iron ore.

The Great Lakes region of the United States contains the main source of US iron ore and one of the world's largest deposits. Of the European deposits, Lorraine is the most famous on the border of France and Germany. The ores found in the Great Lakes region contain about 51 percent iron. And they are close to the surface. It is very simple to extract them: you just need to remove the top layer of the earth and dig the ore. But, unfortunately, these stocks are decreasing.

The iron ores that supply the largest amount of iron are magnetic iron ore, red, yellow and spar iron ore. Magnetic iron ore contains the largest amount of iron compared to others, sometimes up to 72 percent. This mineral is black in color, in which three parts of iron are combined with four parts of oxygen.

The largest deposits of magnetic iron ore are located in the Adirondack Mountains in the state of New York, in New Jersey and Pennsylvania. Magnetic iron ore is also mined in Sweden, Norway, Russia and Germany. Red iron ore is the most common type of iron-containing material, which has found the widest application in the industrial production of iron. It is a soft, free-flowing red ore.

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 liver was taken out, repaired, inserted back 14.08.2003

This is a common procedure in the repair of various machines and devices. But it was first performed by Italian doctors on a human liver, and it was performed successfully.

In December 2001, surgeons at the Hospital of St. Matthew in Pavia removed a liver with a malignant tumor from one of the patients, having previously injected a compound of the amino acid phenylalanine with boron into it. This amino acid is taken up by fast-growing cancer cells six times more than healthy cells, and boron is also taken up at the same time.

The extracted liver was washed and taken to the Institute of Nuclear Physics, where it was irradiated for 11 minutes with an intense neuron flux from a nuclear reactor, then taken back to the operating table and returned to the patient. In total, the organ was absent in its place for 35 minutes. After two or three hours, boron deposited in cancer cells began to emit neutrons, the "charge" of which he received in the reactor. Ten days later, all foci of the disease were destroyed.

Now, a year and a half after the operation, the patient feels great. The team of surgeons is going to apply a new method of treatment to three more patients.
