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. ... >>

Why there is no point in arguing about tastes 08.12.2003

In the human genome, about a thousand genes are responsible for the sense of smell. Of these, more than half do not work. This has been known for several years.

And now Israeli geneticists have found that at least 50 olfaction genes behave differently in different people: they work for some, they are disabled for others. This, apparently, explains the fact that some people like the same perfumes, while others do not. And since the sense of smell largely affects the sensation of taste, fifty variable genes can determine our food preferences. Now the meaning of the old saying "Tastes differ".

The discovery may be of interest to the food and perfume industries: it is possible that it makes sense to produce perfumes, drinks, chips, sweets not for everyone, but for certain genetic groups of the population.
