What is rabies?

Rabies is one of the oldest diseases known to man. If earlier the disease appeared in a person or in an animal, death was inevitable. What is this terrible disease? Rabies is a disease that infects the brain and spinal cord. That's why it's so life-threatening. The infection is caused by a virus, a very small microbe that cannot be seen with a normal microscope.

The rabies virus can infect all warm-blooded animals. A person gets it most often from the bite of a dog infected with the virus. That is why a person who has been bitten by a dog should try to find that dog and check whether it is infected with rabies.

It is not easy to tell when a dog contracted rabies, as the disease does not appear immediately - usually 4 to 6 weeks. At first, the dog becomes passive, has a fever and loses its appetite. Then she gets excited. Saliva foams in the mouth. The dog growls, barks and usually bites. Once these symptoms appear, the dog becomes hopeless. She will die in 3-5 days. In humans, the disease begins more strongly than in dogs.

A person infected with rabies at first becomes passive, has a fever, he feels disgusting. Soon the person feels how the muscles are strongly reduced. When he tries to drink, the muscles of the mouth and throat contract as if in spasm. Muscle spasms are a consequence of changes in the nervous system. But it was believed that this comes from hydrophobia, which is why rabies got a different name - "hydrophobia", that is, "fear of water." This is a misconception about disease.

Death from rabies usually occurs with spasms of the respiratory muscles. It is clear that preventing this is extremely important. The bite site must be thoroughly cleaned and serum administered within three days of the bite. It acts against the virus before it develops and infects the brain. Injections are given every day for 2-3 weeks. All this prevents the penetration of the virus into the body.

How was the Minotaur born?

Once Poseidon sent the Cretan king Minos a sacrificial dazzling white bull, which appeared from the sea. Struck by the beauty of the animal, Minos sent him to graze in his own herds, and sacrificed another bull to the god. Offended by such neglect, Poseidon in revenge made Pasiphae, the wife of Minos, fall in love with a bull. She told the famous inventor Daedalus about her passion, and he decided to help the queen.

He built a hollow wooden cow, covered it with a skin, put it on wheels hidden in the hooves and rolled it out into the meadow where the bull of Poseidon was grazing. Before that, Pasiphae climbed inside the cow through a special door. When the white bull mounted the cow, Pasiphae satisfied her passion. After some time, the Minotaur was born to her - a monster with a bull's head and a human body. Some, however, say that Minos, annually sacrificing to Poseidon the best of the bulls he had, once became greedy and sacrificed the second most beautiful bull, thereby angering Poseidon.

Others say that he offended Zeus. Still others argue that Pasiphae herself did not propitiate Aphrodite for several years in a row, for which she punished her, inspiring such a terrible passion. To hide the shame of Pasiphae, Minos, on the advice of the oracle, turned to Daedalus, and he built the Labyrinth - a dungeon with intricate passages, in the very center of which Minos hid the Minotaur.

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 ... >>

Leader's growl 01.02.2015

Which leader is better perceived by the people - growling like a tiger or shouting slogans in a sonorous voice? It depends on cultural preferences. However, the meaning of the speech may not matter. People determine what kind of leader is in front of them, an authoritarian or a technocrat, by the sound of the voice.

Such a study was conducted by Rosario Signorello of the University of California at Los Angeles, and the idea appeared due to a metamorphosis that happened to the former leader of the Italian League of the North, which advocates the secession of Padania - Umberto Bossi. In 2004, he had a stroke, after which the speech of the politician changed. Ironically, although his beliefs and practices remained the same, voters began to perceive him differently. If earlier in their eyes Bossi was an authoritarian tyrant, then after the blow he began to be perceived as a completely competent person (by the way, it was the popularity of the League of the North that more than once led to the victory of Silvio Berlusconi's party, in Italy he is called "pinocchio" for cunning manipulations, which can be freely translated as "master of the puppet theatre").

Signorello carried out the delexization of speeches - he removed the words from the records, leaving only the overflow of the voice, and tested it on volunteers. Everything turned out as he expected: it was the reduction in overflows in Bossy's speeches that led to a change in attitude towards him. A similar procedure was carried out with the votes of Portuguese and French politicians. The result turned out to be the same: if the main frequency of the voice is low, there are many overflows - the leader is perceived as an authoritarian. If he speaks in a relatively high voice, then the listener unconsciously concludes that it is possible to agree with this person that he will not put pressure on the person.

Signorello comes to the conclusion that the Italians still prefer leaders with authoritarian voices, while the French, on the contrary, do not like them: Francois Hollande is a typical representative of the speakers they like.

Unfortunately, Signorello also did not take into account speech defects, otherwise we might have learned about the magic of light grazing. However, the researcher's interest has now shifted to the voices of non-human primates.
