Does a rattlesnake rattle before attacking?

The rattlesnake is one of those who should be feared. And because people are afraid of her, they made up the story that the snake rattles its tail before biting, thus, as if considering it a little less dangerous.

Unfortunately, this is not always the case. When a rattlesnake rattles, it usually indicates that it is frightened. This causes her tail to vibrate rapidly, so that it seems to rattle. But a study of rattlesnake behavior has shown that 95 times out of a hundred, it does not give any warning before the attack!

By the way, the idea that a rattlesnake, and not only it, attacks more readily than it bites, is also not entirely true. In fact, venomous snakes both attack and bite, but some do it more often than others.

The long hollow venomous teeth of snakes such as the rattlesnake are movable and point inward against the palate of the mouth when it is closed. When the snake is about to attack, it opens its mouth, the teeth take a fighting position, and the snake rushes forward. As soon as the teeth dig into the victim, she stings.

When bitten, poison flows out of the poisonous glands, it passes through the cavity of the teeth and enters the wound. In other snakes, such as the cobra, which have short teeth, the bite is not lightning fast, but lasts for some time, and it seems that they are chewing. With this chewing movement, the snake releases poison into the wound.

But there is no doubt that the cobra is much more dangerous than the rattlesnake. She is much more aggressive, more willing to attack. And although the rattlesnake has more poison, the cobra has more deadly. A man bitten by a cobra dies in less than an hour!

Random interesting fact from the Great Encyclopedia:

What is oxygen?

Often we have to read about something without which "man cannot live." But what a person really cannot live without is without oxygen. Without oxygen, a person can survive only a few minutes.

Oxygen is the most abundant chemical element in the universe. Almost half of the earth's crust is oxygen, and in the air it is more than one-fifth of the total volume. Once in the lungs, it reaches all the cells of the body with the help of red blood cells. In the body, it burns food, producing the heat necessary for human activities.

Oxygen combines very well with other elements. This reaction is called "oxidation". With rapid oxidation, combustion occurs. Almost any oxidation releases heat. When burning, heat is released very quickly, the temperature rises sharply, and a flame appears.

So, on the one hand, we are dealing with combustion - rapid oxidation, as a result of which fire appears, and on the other hand, with oxidation, which processes food in the human body and supports the life support process. We see slow oxidation everywhere. Metal rusts, paint dries, alcohol turns into vinegar - all this is oxidation.

The air we breathe is a mixture of nitrogen and oxygen. Therefore, pure oxygen can be obtained from the air. Air is cooled to very low temperatures, at which it becomes liquid. This temperature is below minus 180 °C. When the temperature of the liquid air begins to rise slightly, the air begins to boil. First, nitrogen evaporates, and oxygen remains. Many lives were saved for patients with weak lungs when they were given pure oxygen to breathe.

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 nurses will scrub the copper 19.05.2005

Staphylococcus aureus, resistant to antibiotics, was bred by the efforts of doctors and patients who used antibiotics where needed and not needed. It occurs on the skin and on the mucous membrane of the nasal cavity in about a third of healthy people and does not harm them in any way. But in a body weakened by disease, staphylococci can multiply, causing persistent infections of the skin, bones, lungs, or blood poisoning.

According to English statistics, this happens in almost 10% of hospital patients, and the number of deaths in England has increased 1995 times since 15. If we take all cases of staphylococcal infection, including those that ended successfully, then their number increased from 210 to 5309.

University of Southampton professor Bill Keevil, who studies the antiseptic properties of copper, suggests replacing stainless steel in hospitals with copper alloys that are toxic to microbes. Stainless steel is considered the most hygienic and antiseptic material for medical instruments, furniture, plumbing and clinic fittings.

However, as the professor's studies have shown, dried staphylococci can remain viable on the surface of steel for up to 72 hours at room temperature. On the contrary, on brass with a copper content of 55%, microbes survive 4,5 hours, and with a copper content of 99% - only an hour and a half. To reduce nosocomial infections, where possible, stainless steel should be replaced with copper and its alloys.

Previously, Professor Keevil showed that bacteria that cause food poisoning survive for several weeks on stainless steel kitchen utensils, but only a few hours on copper utensils.
