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. ... >>

Billions of tons of diamonds discovered in the bowels of the Earth 18.07.2018

Recent studies by scientists from the Massachusetts Institute of Technology (MIT) have shown amazing results: there are billions of tons of diamonds in the Earth's crust.

The initial purpose of the study was to compile a model of the structure of the lithosphere.

Diamonds were discovered using the method of "transmission" of the Earth's surface with infrasonic waves. The wavelength changes depending on the temperature and density of the substance.

Huge reserves of diamonds are located at a depth of 200 km in cratons - sections of the earth's crust that form continents and are located in the central part of the plates.

However, a myriad of precious stones turned out to be inaccessible to mankind - there are no technologies capable of drilling the earth's crust to such distances.
