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. ... >>

Pleasure centers help the immune system 18.07.2016

The feeling of pleasure, the feeling of satisfaction from the work done, from food, from sex, etc. is born in the reinforcement system of the brain - this is the name for a group of interconnected nerve centers, which include both certain areas of the cortex and subcortical areas.

The reinforcement system largely determines the motivation of actions, makes us strive for our goals, and helps to plan actions to achieve these goals. It is known that the placebo effect is also somehow connected with it: when a person takes a medicine, his system of reinforcement works - apparently due to the fact that we feel that we are being treated and everything is going as it should. The trick is that the same reaction occurs in response to a dummy pill, which is passed off as real medicine. But the placebo effect sometimes really helps with illness. Maybe it's all about the signal from the nerve centers of pleasure? It is only necessary to understand where it is moving from the brain and what specific effect it has.

One of the key divisions of the reinforcement system is the ventral region of the tegmentum, which is part of the midbrain. Asya Rolls and her colleagues at the Technion Institute of Technology in Israel excited neurons in the ventral tegmental region of mice, and then took immune cells from these mice and added pathogenic strains of E. coli to them. It turned out that immune cells, after activating the reinforcement system, are twice as effective at killing microbes: both on their own, in the form of a cell culture, and when they enter the body of other mice, in which nothing in the brain was stimulated.

Further experiments showed that the ventral tegmental region influences immunity through the sympathetic nervous system. This is the name of the department of the autonomic (or autonomic) nervous system, whose task is to maintain the work of internal organs in an autonomous mode from the brain (the brain itself, if such a need arises, can interfere with the work of the autonomic nervous system). One of the tasks of the sympathetic department is a reaction to any stress, it mobilizes the body's forces for vigorous activity, increases metabolism, etc.

Stress, on the other hand, is associated with danger: there is a high risk of getting injured and getting infected, so it is quite logical that the sympathetic nerve centers activate the immune system too. And what about the reinforcement system? Given that she feels when an individual has some kind of pleasure, whether it be food or sexual contact. But both are also associated with the risk of infection.
