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. ... >>

Vacuum train speed record 08.02.2024

CASIC Corporation, a Chinese leader in aerospace technology, has set a new speed record for a magnetic levitation vacuum train. This prototype is just a harbinger of future transport, which promises to double this figure.

The vacuum train speed record opens a new era in the transport industry, but the implementation of large-scale projects to implement it will require significant effort and resources.

The T-Flight prototype achieved an amazing speed, exceeding 623 km/h, set in October 2023 as the highest in history for this type of transport.

The test section of the low-vacuum pipe in Shanxi province stretches 2 kilometers, making it the longest structure of its kind. The pressure in the pipe varies from 0,3 to 0,001 bar, while the atmospheric pressure at sea level is about 1 bar.

The main concept of the project is the use of technology that eliminates air resistance and contact with the wheels. These factors typically reduce power and limit the speed of vehicles.

In the next phase, it is planned to increase the length of the route by 30 times, expanding it to 60 kilometers. On such a route, the train will be able to reach speeds of up to 1000 km/h, which makes it almost as fast as an airliner.

In the future, the construction of a highway connecting Beijing and Datong (346 km) will reduce travel time from the current 4,5 hours to just 30 minutes.

However, experts warn that the introduction of vacuum trains may face serious obstacles. These infrastructure projects require the construction of tens or hundreds of kilometers of pipes, which must be completely sealed and provided with constantly running vacuum pumps.
