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 The earth may lose clouds 13.04.2019 Humanity may be forever deprived of clouds. The sky will be absolutely clear every day. The sun will hover over the horizon, stubbornly heating the Earth. The scenario only at first glance seems unrealistic, but this has already happened in the long history of the planet. About 55 million years ago, it warmed up so that crocodiles swam in the Arctic waters. The ocean level rose several meters, flooding vast coastal areas. Many large mammals died out, and those who survived due to lack of food began to decrease in size. Hurricanes raged all over the planet, droughts were replaced by sudden floods. What was the cause of such a cataclysm? American scientists name the culprit: a sharp jump in the concentration of carbon dioxide in the atmosphere. The mathematical model warns that when the concentration exceeds 1200 ppm, there will be a point of no return for the clouds. They will disappear, the Earth will become defenseless from the constant attack of the Sun, which will lead to a sharp warming of the ocean. And further down the chain: the average temperatures on the planet will rise by about 8 degrees, the most powerful natural disasters will break out, the mass extinction of animals and plants. This version immediately found opponents. They pointed out that the 1200 ppm milestone is nearly three times the current CO2 concentration. So, there is no need to panic. But the authors of the study insist: look at how rapidly this concentration is growing. For some 60 years - an instant by historical standards - the level of gas has risen by almost a third. At this rate, the point of no return will be passed in the next 100 years. How inevitable is such a scenario? Today, science cannot unambiguously answer why the concentration of carbon dioxide is increasing. Someone blames a person who pollutes the atmosphere with emissions, someone is convinced that nature works with its natural cycles. And they remind that there was already a "cloudless" life, although no man was observed on the planet. The authors of the study believe that whatever the cause of the phenomenon, this time mankind will be able to save the clouds. Science will find a way to avoid a catastrophic scenario. Growth in recent decades, the increase in the average temperature on Earth is uneven. For example, in the Arctic it is twice as fast as in the rest of the planet. How will this affect the climate in other regions? A study by American and Belgian scientists showed that the warming that occurred 11-8 thousand years ago in the Arctic region created the prerequisites for drought in the middle latitudes.
