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. ... >>

Probiotics and pregnancy 03.02.2018

Milk with probiotics helps to avoid two serious problems that pregnant women often face at once: these are premature births and preeclampsia (the so-called form of late toxicosis during pregnancy, when blood pressure rises very much and protein appears in the urine).

Employees of the Sahlgrenska Academy at the University of Gothenburg, together with colleagues from other research centers in Sweden and Norway, analyzed medical statistics relating to approximately 70 pregnant women who participated in a long-term medical study. As part of this study, women were asked how they felt, what they ate and what they did before pregnancy and at different stages of pregnancy.

Probiotic milk is generally very popular in Norway, with about 23% of women reporting that they drank probiotic milk before pregnancy, another 38% that they drank it until the thirteenth week, and another 32% that they drank probiotic milk during late pregnancy. that is, between the thirteenth and thirtieth weeks; the average portion was one and a half cups a day.

Milk was accompanied by a clear beneficial effect, but everything depended on the stage of pregnancy. For example, the likelihood of preeclampsia was reduced by 20%, but only when probiotics were taken late in pregnancy. On the other hand, the chance of preterm birth (that is, before 37-1 weeks) was reduced by 21% only when probiotic milk was drunk during early pregnancy.
