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. ... >>

High-speed network will unite scientists from China, Russia and the USA 07.01.2004

Soon Chinese, Russian and US scientists will be able to collaborate using a new high-speed network that will include the first direct link across the Russian-Chinese border.

An information highway separate from the public Internet networks will allow scientists to quickly exchange huge amounts of information and conduct various joint experiments in real time.

Russian and US scientists have been using a direct connection for about 5 years, but the exchange of information between the Russian and Chinese sides often took place at meetings in the US. The last work should be completed on the Russian-Chinese border, and on January 5, according to the plan, the network should pass the first traffic.

The ring of the network will run across the northern hemisphere, connecting Chicago, Amsterdam, Moscow, Siberia, Beijing and Hong Kong. The US National Research Foundation allocated 2,8 million USD for the creation of the network, Russia and China also contributed comparable amounts.
