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. ... >>

Random news from the Archive Trap of eternal desires 10.08.2022 Research shows that people are constantly trying to get more and more things, such as a new smartphone, or clothes and shoes, although this does not always bring them happiness. American scientists have found out what explains such a desire for a large number of new material goods. "People constantly strive to be happy and often this happiness lies in material things. A person constantly needs more and more. But many people cannot achieve happiness in their imagination and this causes depression. Therefore, people fall into the trap of "eternal desires" when for to find happiness, they need more and more things. But as studies show, this does not always lead to the desired result and people become, on the contrary, unhappy. Our study explains why we continue this eternal struggle, although it negatively affects us, "says Rahit Dubey from Princeton University, USA. Scientists believe that our brain is programmed to have more and more material goods. This is due to the fact that a person is constantly worried about the difference between what he has and what he wants to have. Also, a person in search of happiness often focuses on his past experience. For example, you traveled last year and had a good time, and you expect a similar experience to repeat. Also, scientists have come to the conclusion that we are constantly striving for more because of getting used to a good life, and we are also influenced by different social standards. Scientists have created computer models that mimic the way the human brain works, which can match different situations with different actions. Research has shown that even getting what you want doesn't really make you happy. We constantly compare ourselves with other people and strive to meet certain standards, as well as trying to repeat past positive experiences. On the other hand, as scientists say, if a person is not satisfied with what he has, he tries to improve his situation. But it's almost an eternal struggle. "Our research also shows that in the pursuit of happiness, we often devalue what we already have, and this leads to depression and overconsumption, that is, the acquisition of more and more material things," Dubey says. But scientists say they need to be careful about the results of their work, because a computer model may not fully correspond to human behavior.
