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. ... >>

The oldest black hole in the universe has been found 10.12.2017

American astronomers from the Carnegie Institution announced the discovery of a new galaxy, in the center of which is a supermassive black hole. Scientists suggest that the galaxy formed 690 million years after the Big Bang.

The galaxy and black hole formed during the era of reionization - it is believed that at this time the universe was covered with clouds of neutral hydrogen, which blocked most of the starlight. Over time, quasars, considered one of the strongest sources of energy in space, ionized the hydrogen, causing the universe to become "brighter".

The new galaxy was named J1342 + 0928. During its study, it turned out that the galaxy is especially rich in metals. Astronomers have noted that this is typical of the very first stars, which consisted almost entirely of hydrogen and helium.

Also, in the accumulation of interstellar dust, astronomers found a large amount of carbon, and in the very center of the galaxy, where the black hole is located, nitrogen, magnesium and even silicon.

Such observations can say one thing: this is a new, previously unknown type of star formation, shared Eduarda Bansados, lead author of the study.

Scientists speculate that the early universe contributed to the formation of massive, unstable stars that exploded after a few million years, producing metals faster than the universe in its current state. New stars were already formed from the "remains" of the former ones, thereby accumulating heavy elements in themselves, the authors of the study concluded.
