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. ... >>

Sex problems on Mars 03.06.2018

The idea of ​​colonizing Mars is not just science fiction; NASA and space agencies around the world are working hard to determine what it will take for humanity to take root on the Red Planet. Humankind faces various problems, such as growing food sources or an unfavorable habitat. But the biggest problem for colonization, scientists see - sex.

In a new research paper, an international team of scientists is studying the problems of humans being born on the surface of Mars.

The first and most obvious obstacle is the low gravity environment, which can pose a serious threat to the processes of conception and pregnancy, which seem so simple on Earth. Scientists are aware of the problems of astronauts who have spent months and in some cases years in space. Lower gravity causes muscles to deteriorate rapidly and can even weaken bone structure. In addition, astronauts sometimes experience vision problems and even changes in the shape of their brains.

The study explores the inherent challenges of sustaining a small colony of settlers on the planet. The concept of "love" should not stand in the way of survival. In addition, some people will never be allowed to have children due to undesirable traits that pose a danger to the colony as a whole.

But the most frightening thing is that in the course of colonization, a new kind of person may appear that can thrive on Mars, but cannot live on Earth.
