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 Bacteria will slow down the melting of ice cream 15.10.2015 Scottish scientists from the University of Edinburgh and the University of Dundee have been able to slow down the melting of ice cream using a protein that changes the properties of the product. The protein, known as BsIA, is commonly found in aggregations of microorganisms called biofilms. It turned out that he is able to change some properties of ice cream, in particular, to make it more resistant to temperature effects. Most bacteria naturally live inside biofilms, and the external structure of these objects becomes stable due to the many molecules secreted by cells. For example, BsIA is responsible for creating a hydrophobic layer on the outer surface of a biofilm. However, the specific properties of a protein allow it to also allow free mixing of substances that normally repel each other, such as water and oil. The most important role in ice cream is played by the interaction between fat and water, so the addition of BsIA stabilizes the structure and slows down its melting. The Scots made a test batch of ice cream with the addition of BsIA protein in the laboratory, but none of them dared to taste it. Scientists only noted that in terms of density and texture, ice cream is absolutely identical to traditional ice cream. Now the developers intend to bring their product to mass production and hope for an impressive commercial success. However, British chef Heston Blumenthal has already launched his own non-melting ice cream. Unlike the Scots, its composition is kept in the strictest confidence, but everyone can try it - and make sure that the vanilla cone tastes no different from the usual ice cream.
