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. ... >>

Found a place with lifeless soil 26.07.2021

Near the Shackleton Glacier in Antarctica found places with lifeless soil.

The discovery greatly surprised scientists, as viable microbes were found in the most adverse conditions on Earth: from red-hot hydrothermal vents to the top of Everest. However, of 204 soil samples collected near the Shackleton Glacier, about 20% did not contain traces of microbial DNA.

According to microbiologist Noah Firer, this is the first time scientists have found soil that doesn't seem to support any microbial life.

The findings suggest that extremely cold and dry conditions can severely limit the habitability of microorganisms.

"We do not claim to have found 'lifeless' or 'sterile' soils, or to have determined a low temperature threshold for life. But our failure to detect microbes or microbial activity in certain soils suggests that these surface soils represent a cold limit for microbial activity and survival. , dry and saline environmental conditions," the authors of the study emphasized.

Given that the Martian lands are much older, are in similar or harsher conditions than on the Shackleton Glacier, and also contain even higher concentrations of salts, the search for active life in the surface layers of the planet is unlikely to yield positive results, microbiologists say.

Some experts believe that current technology is unable to detect very low concentrations of microbes, leading to false negative results.
