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. ... >>

Reducing the altitude of aircraft will help the environment 19.02.2020

A group of scientists from the British Imperial College London and the German Institute of Atmospheric Physics proposes to adjust the flight altitude of individual flights in order to reduce the impact of the contrail on global warming.

Behind each flying aircraft, a contrail is formed, consisting of a dense layer of small ice crystals that do not dissipate for tens of hours and prevent heat from being reflected from the Earth. Contrails are especially harmful at night, when they return the heat reflected from the surface back.

Using data collected by the Japanese authorities from 2002 to 2013 on the movement of aircraft, scientists have found specific altitudes at which flying liners leave the most persistent contrails. To get rid of them, it is necessary to change the flight altitude of aircraft - even taking into account the increase in fuel consumption and the level of emissions of carbon dioxide and other greenhouse gases, the effect on nature will be positive.

The authors of the study emphasized that a relatively small proportion of flights, which predominantly take place in the afternoon, will undergo height adjustments. If the proposed measures are implemented, the effect of contrails on global warming will decrease by 91%, aviation will reduce its harm by 56%.
