Comments on the article

It has long been known that blueprintsin the workshops become so dirty and obscure over time that the numbers and sizes indicated on them are often impossible to make out.

In order to protect drawings made in ink or pencil from contamination, we advise you to put them on glass or on a board and cover them with collodion, to which 20% stearin is added. After 15 minutes it dries to a pure white color with a matte finish.

Thus, the drawing is covered with a protective layer that can be washed with clean water without fear of washing off the drawings and numbers.

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. ... >>

Erasing memories 29.07.2020

Fantastic plots of films and novels tend to become reality. For example, "memory erasure" is often mentioned in them. Success in this direction was achieved by researchers from Italy. They mastered the technique of removing unpleasant memories from a person’s memory. It is assumed that it can become the foundation for creating approaches for the effective treatment of mental disorders and post-traumatic syndrome.

Memory erasure is based on the effect on the brain using transcranial magnetic stimulation. By acting on the brain with a magnetic field and directing it to certain zones, it is possible to change their electrical activity. By doing this in an orderly manner, scientists have learned to achieve the results they need. For example, TMS can be used to treat Alzheimer's disease, improve math skills, and reduce cravings for smoking and other bad habits.

Scientists have figured out in detail how memories arise in the brain. They highlighted the presence of such a phenomenon as memory reconsolidation. This term refers to the periodic recall of memories from long-term memory, reinforcing them. It is characterized by the so-called "window of variability", when the memory can be influenced and corrected. Knowing this and applying a magnetic field to areas of the prefrontal cortex of the brain, one can remove unpleasant memories associated with stress.

To confirm this theory, a demonstrative experiment was conducted with the participation of 100 volunteers who volunteered to serve science. They were asked to view a selection of photographs with a neutral theme. While watching, they were electrocuted, inflicting unpleasant electric shocks. This caused an association between the photo and the pain. The next day, they were asked to recall their experiences and had a TMS session. Then, their memories were checked again. It turned out that they were freed from the fear of electric shock, although they did not forget what happened to them a few days ago.
