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. ... >>

FGF21 injection helps sober up 13.03.2023

American researchers sobered mice by injection of the hormone FGF21, which reacts to the introduction of ethanol into the body. The connection allowed the animals to regain consciousness and coordination of movements twice as fast.

The FGF21 hormone is produced by the liver under the influence of a number of stress factors, such as starvation, lack of protein, or the action of ethanol. Previous studies have shown that the compound protects the liver from damage due to alcohol consumption, as well as reduces alcohol cravings and encourages drinking more fluids to prevent dehydration. Behavioral change means that the action of the hormone crosses the blood-brain barrier to the brain. Scientists at the University of Texas Southwestern Medical Center and colleagues decided to clarify the mechanism of its action.

First, the scientists heavily ethanoled two groups of mice - normal and blocked by the hormone FGF21. Although within 15-20 minutes they all became intoxicated and lost the ability to navigate in space, it took 1,5 hours longer for the modified animals to recover the reaction. At the same time, the rate of elimination of alcohol from the blood of animals was the same. Therefore, FGF21 protects against the consequences of ethanol consumption, but does not affect its metabolism.

In the next experiment, an hour after drinking, when the mice were already unconscious, half were given an injection of the hormone. As a result, consciousness and orientation in space recovered 1,5 hours faster than those who did not receive injections, and this is equal to a reduction in the time of intoxication by about 50 percent. The action of FGF21 appeared to be specific to ethanol, as it did not promote sobering after sedative compounds such as ketamine, diazepam, or pentobarbital.

The researchers found that the effect of FGF21 is due to its effect on the noradrenergic neurons in the locus coeruleus - parts of the brain that regulate arousal and alertness. This means that targeting these neurons, mimicking the action of FGF21, could help bring people out of high inebriation. But whether the mechanism of the hormone will work in humans in the same way as in mice should be clarified in the following studies.
