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.

Down's syndrome cured in mice 05.10.2007

Children with Down syndrome have an extra 21st chromosome (instead of two - three), which affects their appearance, and also reduces memory, learning ability, rational activity to varying degrees, and makes it difficult to master the language. A few years ago it became clear that these neurological disorders are associated with excessive synthesis in the brain of gamma-aminobutyric acid (GABA), which inhibits the activity of neurons.

An employee of Stanford University (USA) Craig Garner and his colleagues, using genetic engineering, brought out a line of mice with an extra 21st chromosome. They also had impaired memory and learning ability. Various GABA antagonists have been tested in these mice, with pentylenetetrazole being the most effective. This medication was used in the United States in the 50s against depression and psychosis, but it soon became clear that it causes epileptic seizures.

Experiments have shown that mice with Down's syndrome, given a small dose of pentylenetetrazole, become smarter and quickly learn to find their way through a maze. Moreover, the effect persisted for three months after treatment (on the scale of human life, this is about nine years).

The authors of the study believe that it will be several more years before the start of treatment for people with Down syndrome.
