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. ... >>

11 densely populated systems discovered in the universe 01.02.2012

A team of scientists working with data from the Kepler telescope reports the discovery of 26 new planets, which make up 11 planetary systems. Each of the systems includes from two to five planets of different "caliber": there are also small planets, only 1,5 times the size of the Earth, and gas giants, much larger than Jupiter.

The size of 15 discovered planets is in the range between Earth and Neptune. In the course of research planned for the near future, scientists plan to find out which of the planets have a solid surface and which are gas giants. The most distant of the discovered planets makes one revolution around its star in 143 Earth days, the least distant - in 6 days. The maximum distance from the star does not exceed the distance between the Sun and Venus.

The most "densely populated" system of the star Kepler-33 consists of five planets ranging in size from 1,5 to 5 Earth. Moreover, all five are located very close to the star: the distance from the star to the most distant planet does not exceed the distance between the Sun and Mercury. Experts also revealed a number of interesting patterns. Five of the eleven systems - Kepler-25, -27, -30, -31 and -33 include two planets each, in which the period of rotation of the inner one is half that of the outer one. In four planetary systems - Kepler-23, -24, -28 and Kepler-32, the orbits of pairs of planets correlate as two to three. With this arrangement, gravitational interactions between the planets are enhanced, due to which the speed of movement along the orbit is constantly changing: one planet from a pair accelerates, the other slows down. After some time, the interaction leads to the opposite effect.

The existence of 26 of these planets has been confirmed by repeated observations. In addition to them, other planets can be located in the systems, the existence of which has not yet been confirmed for the reason that they spend much more time on one complete revolution around the star.
