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. ... >>

Churches of Halley 05.09.2005

Everyone knows Halley's comet, but only historians of science remember that this professor of geometry at Oxford University published a scientific article in 1714 on "variations of the magnetic compass." In 1711, the English Parliament passed a program to build 50 new churches in East London to combat atheism and false beliefs. As a result, however, only 12 churches were built (the political situation has changed).

Now archaeologists have noticed that the foundations of two of these buildings - the churches of Christ the Savior and St. Anna are oriented along the east-west axis with great accuracy.

Considering that the architect of these two temples was familiar with Halley for thirty years, and the professor himself was a member of the London building commission and actively attended its meetings in 1714, it is very likely that he used the results of his research on the deflection of the magnetic needle to help the builders.

The irony of history: now in many areas of London it is impossible to accurately navigate by compass, as man-made magnetic fields interfere, for example, from the subway.
