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. ... >>

Gene therapy cures deafness 05.11.2023

Gene therapy has provided a breakthrough in the treatment of congenital deafness, allowing the first children to hear sounds. Chinese researchers, together with a team of scientists from the pharmaceutical company Regeneron, have successfully eliminated a genetic defect in the otoferlin gene.

Both groups of scientists have developed and are testing gene therapy targeting the otoferlin gene. This gene, if defective, disrupts the transmission of signals from the hair cells of the inner ear to the vestibulocochlear nerve, which is responsible for the perception of sound vibrations. Gene therapy seeks to restore normal levels of the otoferlin protein by introducing a working copy of the gene into inner ear cells using modified adenoviruses through a single injection into the helix.

Regeneron just announced in mid-October the start of trials of gene therapy for deafness in children in the US, UK and Europe, and has already received encouraging results. In one case, a child under two years of age who received an injection in one ear was able to regain hearing after six weeks, which was confirmed by behavioral audiometry and brainstem response.

Chinese scientists from Fudan University provided information on ten children who participated in their study. As a result, hearing was restored in four children, although the method did not work in one child, possibly due to immunity to the virus used as a gene delivery agent.
