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. ... >>

Bees and math 30.09.2018

A tiny brain is not a sign of a lack of intelligence. This conclusion was reached by scientists from France and Australia, who studied the mathematical abilities of bees, namely their ability to understand the position of zero in a series of numbers.

For the study, white plates with dots were used. Food was laid out on them in a certain order. Real food was placed on plates with the fewest black dots. The rest were covered with quinine solution. During the experiment, the bees quickly realized that the largest amount of real treats, and not quinine, is on a plate with a zero indicator, that is, where there were no points at all. From this, scientists concluded that bees are able to count up to five, and also understand what zero is.

According to the researchers, "Zero" is a rather complicated mathematical concept. For a very long time it was believed that only a person is capable of realizing it, because he has abstract thinking. However, earlier experiments had shown that birds and monkeys could also detect zero.
