Why don't women have beards?

As feathers characterize birds, hair characterizes mammals. Why do mammals have hair (fur)? There are various reasons. Let's look at some of them.

The main value of hair is that it retains body heat. In the tropics, they can perform the opposite function. Some tropical animals have wool that protects them from the sun's rays. Very long hair on certain parts of the body serve special purposes.

For example, a mane can protect an animal's neck from an opponent's teeth. Tails can be used to beat flies. Tufts on the head can attract individuals of the opposite sex. The rigid quills of the porcupine, arranged in a fan, help him to attack the enemy. Hair or wool can also serve as organs of touch. Cats have special nerves on their whiskers that respond instantly to touch. So you see that hair in different mammals can serve different purposes.

What can be said about a person? We know that beautiful women's hair can be very attractive to men. But let's assume that earlier the hair of a person formally played a greater role than it does now. The baby is born with almost no hair. Soft, light hair soon appears. After the onset of puberty, the hairline changes and becomes the same as in an adult.

Hair development is regulated by the gonads. Male sex hormones promote the growth of body and facial hair. On the head, hair grows more slowly. Female sex hormones act just the opposite. They promote good hair growth on the head and resist hair growth on the face and body.

Women do not have mustaches and beards because the action of various glands and hormones in their body specifically prevents their growth. To explain why this is so, and why male hormones and glands promote beard growth, we must go back to early human history.

Previously, probably, the function of the beard was to be able to easily distinguish a man from a woman from afar. Perhaps the beard gave men a sense of power and dignity, making them more attractive to women. Nature helped men attract the opposite sex to them just as she did with other living beings.

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 ... >>

Words and their emotional coloring 11.01.2019

Researchers at the University of Göttingen studied how the brain processes words to associate positive or negative emotions with them.

In the human mind, many objects and people in everyday life have an emotional meaning. For example, a pair of woolen socks has emotional value if it was the last thing a grandmother knitted before she died. The same applies to words. The stranger's name doesn't have an emotional connotation for you at first, but if a love relationship develops, then even the name suddenly takes on a positive connotation.

Scientists from the Institute of Psychology. Georg Elias Müller at the University of Göttingen analyzed how people attach emotional meaning to initially neutral signs, words and faces. For hours, participants explored these connections through a process of systematic rewards and losses. For example, if they received money every time they saw a certain neutral word, it acquired a positive emotional connotation. Conversely, if participants lost money every time they saw a certain word, it became negatively colored. The study also showed that people reinforce positive associations much faster than neutral or negative ones.

Using electroencephalography (EEG), the researchers also analyzed how the brain processes various stimuli. The brain usually determines whether an image or word is positive or negative in about 200-300 milliseconds. “Words associated with loss elicit specific neuronal responses in the visual cortex in as little as 100 milliseconds,” says Dr. Louise Kulke, first author of the study. “In this way, the brain instantly recognizes how important a new word is to us, especially if it is value is negative."

It also seems to matter whether the word is already known to the subject (for example, "chair" or "tree"), or whether it is a fictitious word that does not exist in the language (for example, "napo" or "foti"). Thus, the existing semantic meaning of the word also plays a role in the nature of the emotions that we attach to it.
