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. ... >>
Random news from the Archive radioactive thunderstorm
01.02.2001
Physicists from the University of Bologna (Italy), having installed radioactivity sensors on the Gran Sasso mountains, found that gamma radiation appears during thunderstorms. Moreover, two types of radiation were revealed.
The activity of one, with a photon energy of up to three megaelectron-volts, increased slowly, lasted for about an hour, and just as slowly fell. It is believed that aerosol radioactive particles hovering in the upper atmosphere fall to the ground with rain.
Another type of radiation is bursts with energies up to 10 megaelectronvolts lasting several minutes. Apparently, powerful electric fields accelerate free electrons present in the air, and when a fast electron collides with atmospheric atoms, so-called bremsstrahlung gamma radiation occurs.
