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. ... >>

Satellite for creating artificial starfalls 20.01.2019

The Japan Aerospace Agency, using the Epsilon-4 rocket, launched seven satellites into Earth orbit, one of which will be used to create artificial starfalls.

The satellite was developed by Tokyo-based startup ALE. On board are 400 metal balls. At the appointed time, they will "shoot" from the satellite and fly towards the Earth, burning up in the process of flight in the upper atmosphere - from the surface of the planet it will look like a stream of meteorites.

The first artificial starfall is scheduled for the spring of 2020 - it will be carried out over Hiroshima.

ALE believes that if the weather is good, several million people will be able to observe the phenomenon. It is assumed that 20 balls will be enough for one meteor shower - thus, the reserve on the satellite will be enough for two dozen launches.

The composition of the alloy from which they are made is kept secret - the company notes that due to its composition, the balls will burn in the atmosphere longer than real meteorites.

A random story from the life of a radio amateur:

I am often busy with work, and at this time clients come (of different nationalities, including Georgians) and ask: "My TV has a defect such and such. What can be damaged?" To politely get off, I answer my magic word: "Maybe C7" (c-seven). No more questions are asked, the TV is brought in for repair. Only one client asked where this "C7" is located. I politely answer: "Near C8." He says: "Ah! I see!" And without further ado brought the TV for repair.
