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. ... >>

Less work in winter 20.12.2019

For many of us, winter, with its short cold days and long frosty nights, makes us feel unwell. It is more difficult for us to wake up and it is very difficult to force ourselves to work. As a result, we fail.

For a small portion of the population that experiences seasonal affective disorder (SAD), things are even worse - winter turns into a debilitating blues. At the same time, people experience hypersomnia (daytime sleepiness) and they are more often in a bad mood than a good one. In addition, they experience a pervasive sense of worthlessness. Depression is a common occurrence for the winter period. Suicide rates are on the rise and productivity in the workplace is falling. Especially in January and February.

All this is easily explained by winter gloom - a rather vague idea. But there is also a scientific reason for SAD. If our internal clock is out of sync with our work schedule, shouldn't our workday be adjusted to match it?

“If our internal clock tells us to wake up at 9:00 because of a dark morning, but we still get up at 7:00, then we cut our sleep,” says Greg Murray, professor of psychology at Swinburne University (Australia). Research in chronobiology—the study of how our body regulates sleep and wakefulness—supports the idea that sleep needs change in winter, and the limitations of modern life during the winter months are unacceptable.
