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 Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

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. ... >>

Memory depends on the time of day 21.12.2019

If you're trying to remember something and you can't, don't get discouraged - try to stretch your memory at other times of the day, and, quite possibly, you will remember everything you need

Researchers from the University of Tokyo and Tokyo Agricultural University showed mice different objects to remember them, and then, after some time, observed how well the mice remembered them. If the mouse studied the subject for a short time, it means that it remembered it quite well, and if it took a long time, it means that it managed to forget it. The objects were shown to mice just before when the animals usually wake up (that is, in the evening, because mice are nocturnal animals), and their memory was checked either a day later, that is, again before natural awakening, or immediately after the mice usually went to sleep (that is, eat very early in the morning). In the first case, when a day passed between acquaintance with a new thing and remembering, the mice did not remember it well; in the second case, when the thing was shown to them after they were supposed to fall asleep (but they showed it, of course, to awake mice), they remembered it well. The same results were obtained when it was necessary to get acquainted not with an inanimate object, but with another mouse.

But the experiment was set up not only with ordinary mice, but also with mutant mice in which the BMAL1 gene did not work. This is one of the main genes that control circadian rhythms: the level of the BMAL1 protein changes during the day, and as it changes, it turns on or off many other genes. (You can learn more about it in one of our articles.) In general, mice with BMAL1 turned off forgot and remembered in exactly the same way, only they forgot more strongly - when a familiar object or mouse was shown to them a day later, they clearly remembered them worse than normal animals with working BMAL1. That is, firstly, memory clearly depended on the time of day, which neuroscientists have suspected for a long time, and, secondly, memory processes depended on an influential clock gene.

The clock protein BMAL1 stimulated the work of dopamine receptors and modified a number of signaling molecules in one of the zones of the hippocampus, which, as we know, is one of the main brain memory centers. Perhaps, using the signaling pathways that are affected by the BMAL1 gene, it will be possible to create some kind of memory enhancer. Although why memory is subject to circadian rhythms at all remains a mystery - it is possible that this is simply a side effect of the circadian rhythms.
