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 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. ... >>

Schoolchildren who skip breakfast perform worse
14.10.2023
Pupils who skip breakfast on school days get lower grades than those who eat regularly before school starts, according to a new study in Yorkshire, UK.
Dr Katie Adolph, from the School of Psychology at the University of Leeds, lead author of the study, said:
"Our work shows that high school students are at a disadvantage if they skip their morning meal, not providing the brain with the resources it needs to start the school day."
A survey of 294 pupils from schools and colleges in West Yorkshire found that 29% rarely or never ate breakfast on school days, 18% ate breakfast sometimes and 53% did so regularly.
When analyzing academic performance, the researchers found that students who ate breakfast infrequently scored 1,20 points lower on average than those who ate before school, controlling for other factors.
This study provides valuable data highlighting the importance of breakfast in improving student achievement and overcoming barriers to education. Because education plays a key role in a child's future success and lift out of poverty, ensuring every child has a healthy start to the day should be a priority for parents.
