How does altruism manifest itself in the behavior of rats?

Altruism is characteristic not only for humans, but also for many animals in one form or another. Even rats, as experiments show, willingly help their fellows without benefit to themselves. In the first experiment, two rats were placed on the platform, one of which was locked in a narrow cylinder, and the free rat almost always tried to rescue it from captivity. In a complicated experiment, in addition to the cylinder with the rat, a container with chocolate chips was placed on the platform, which the free rat could easily eat on its own. However, in this case, she first released a friend to share a delicacy with him.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

The hearts of the singing choristers are in sync 24.07.2013

Singers who sing in a choir synchronize their heartbeats, and as a result, their pulse speeds up and slows down at the same time, according to a study by scientists from the Salgren Academy at the University of Gothenburg (Sweden). Now scientists have precisely defined what it means to "sing in unison."

The purpose of the study by Swedish scientists is to study the effect of music on our body and health and to find new forms of using music for medical purposes, primarily within the framework of rehabilitation and preventive care. In this part of the study, scientists have already proven that music affects the heart rate of each chorister.

The experiment involved 15 students from a school in Gothenburg. They were asked to perform three choral exercises: monotonous humming, playing a well-known Christmas carol and chanting mantras. In each case, the researchers recorded the heart rhythms of all the participants in the choir. The results of the study showed that music has a direct effect on the heartbeat of each chorister, and at the same time, the pulse of all singers is synchronized during singing - it speeds up and slows down at the same time.

According to scientists, people who sing regulate the activity of the vagus nerve, which is involved in our emotional life, affects communication with other people, as well as the timbre of our voice. As it turned out, songs with long phrases have the same effect as yoga breathing exercises. Researchers suggest that through singing we can control our mental state.

The impact of choral singing on health has only just begun to be studied, but a positive effect is already noticeable. According to scientists, the benefit of choral singing is that it calms our breathing, normalizes the heart rate, and this, in turn, has a positive effect on health.

In the case of controlled breathing, the pulse rate and heart rate decrease on exhalation and then increase on inspiration. Exhalation activates the vagus nerve, which lowers the heart rate and slows the pulse. The fluctuation in heart rate between inhalation and exhalation is called sinus respiratory arrhythmia. This is a type of physiological arrhythmia that is best expressed in young healthy people who are not subject to stress. And, according to scientists, the song helps to control breathing: during the chanting of phrases, exhalation occurs, and in the pauses - inhalation.

Choral singing helps develop the skill of controlled breathing. In addition, the pulse and heartbeat of the choristers are synchronized during the performance

Now the researchers intend to understand how the synchronization of the heart rate during choral singing will create a favorable psychological atmosphere for strengthening the ability to cooperate and communicate people.
