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. ... >>

24-pin ATX connector will be replaced by 10-pin 31.01.2020

The PC market, of course, is more inert than the smartphone market, but even here everything is changing, and in recent years it has been very active. It is enough to take the processor segment, where less than three years have passed since the release of the first Ryzen CPUs, and there have been more changes than in the previous ten.

But among all that is changing, there are a number of features that remain unchanged for years and even decades. In particular, a large 24-pin connector, through which power is supplied from the block to the motherboard, is known even to those who are very far from the PC world - it’s enough just that a person sometimes opens the case to clean it from dust.

This connector belongs to the ATX standard, which was adopted 25 years ago and began to become active in the market about 20 years ago. And soon he will finally retire.

According to the source, Intel intends to introduce a new connector - ATX12VO this year. It will change not only externally, but also electrically. As you know, now the main components of the PC are mainly powered by 12 V, however, the 24-pin connector also supplies other lines (3,3 V and 5 V) to the motherboard. In the case of ATX12VO, everything will change - all lines will be 12-volt, and the motherboard itself will deal with the conversion. In addition, the connector will become 10-pin, which will make it much more compact.

Most likely, at first only PC manufacturers will completely switch to the ATX12VO standard, and components for self-assembly will continue to use the old connector for some time. A full transition to the new standard will obviously take more than one year.
