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. ... >>

Sculptures from the bottom of the Rhone 05.01.2009

For about ten years, French archaeologists, wearing scuba gear, have been descending into the Rhone River near the city of Arles. Despite a very strong current and poor visibility, often not exceeding half a meter, among the many modern debris, including even sunken cars, scientists find items related to antiquity (the Roman port was founded here by Julius Caesar in 46 BC).

Among the finds of last year, there are several statues of remarkable craftsmanship: a marble Neptune taller than a human being, a bronze statue of a satyr, a bronze bas-relief of Nike... But the marble sculptural portrait of Julius Caesar is considered the most valuable find. This, as far as is known, is the oldest surviving image of the emperor and the only lifetime.

How did these works get to the bottom of the river? It is believed that the sculptures were thrown into the river during the riots associated with the change of power and the advent of Christianity.
