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. ... >>

Acoustic waves for the treatment of muscle injuries 15.07.2016

Specialists from the University of Salzburg (Austria) found that exposure to acoustic shock waves has a positive effect on the recovery of damaged muscles and can be used as a promising therapy for athletes in the future.

The work of specialists is devoted to extracorporeal shock wave therapy (Extracorporeal Shock Wave Therapy or ESWT) - a method of treating diseases of the musculoskeletal system using acoustic shock waves of low power. This therapy has proven itself in the treatment of ligaments and tendons, but the Austrian scientists decided to go beyond the usual scope and tested what effect ESWT would have on muscles.

"As far as we know, no one has conducted experiments that would show how beneficial ESWT affects muscle damage - one of the most common causes of injuries in playing sports. ESWT can accelerate the healing process of muscles, allowing athletes to return to sports in the shortest possible time ", says Angela Zissler, PhD at the University of Salzburg and lead author of the study.

Shock wave therapy stimulates tissues mechanically, accumulates and triggers the division of stem cells that replace dead cells in the body. According to the study, shock waves stimulate signaling factors in muscle tissue. These factors, in turn, trigger the work of progenitor cells, which up to a certain point are at a low level of differentiation, but at the right moment begin to develop into an adult cell, and then into muscle fibers.

Zissler believes that ESWT has great promise in the field of sports injury treatment. The low frequency (about 1 beat per second) and low power (less than 0,2 mJ/mm2) of acoustic shock waves make it possible to use therapy without resorting to painkillers. The therapy is non-invasive, takes no more than 15 minutes and has no side effects, which means it can compete with traditional physiotherapy.
