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. ... >>

Contact lenses are dangerous for nature 23.08.2018

According to scientists, only US residents wash up to six tons of lenses a year down the drain. This seems to be a little, but we are talking about a material that is resistant to natural decomposition. Many people use contact lenses to improve their vision. This device, simple in modern times, does not last long: from several months to one day. And then they throw him out. Very often - flushing down the drain.

The researchers analyzed the likely future fate of the five polymers that make up the lenses. It turned out that, once in an environment populated by bacteria, the lenses slowly disintegrate into very small fragments, which, in the future, can be eaten by a variety of bottom dwellers, who, for millions of years of evolution, have not been taught to separate organic matter made by man from natural.

Since these plastics are actually indigestible, their entry into the food chain promises trouble for all further participants in it, up to people who will sooner or later end up with fish and seafood "with eyes".

The study participants hope that contact lens manufacturers will pay more attention to how their products are disposed of after use.
