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 ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. 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. ... >>

Microparticles in aerosols increase rain and wind 10.02.2018

Researchers at the University of Maryland have studied how particles of various sizes flying through the atmosphere change the intensity of rain, wind and other weather events. They found that very small aerosol particles (up to 50 nanometers in diameter) significantly accelerate convection and precipitation.

The experiments were carried out in the Brazilian state of Amazonas, where the air is still quite clean. Such a place was chosen to minimize the influence of those particulate matter that are already in the atmosphere in the area. Weather phenomena over part of the state of Amazonas were observed with the help of special instruments. We also built computer models of the influence of very small aerosol particles on air humidity and the formation of large water droplets in clouds.

It turned out that very small particles very intensively collect water drops around them, if there are practically no larger solid particles in the atmosphere. This is especially evident in a warm and humid climate, such as in the territory of Amazonas. When water droplets form, heat is released, and the air heated by this heat rises quickly, that is, intense convection occurs. In this case, the relative humidity of the air can significantly exceed 100 percent. Atmospheric currents are becoming more intense, as a result of which precipitation is accelerating and wind is increasing.

It was previously thought that particulate matter less than 50 nm in diameter was simply too small to play a significant role in atmospheric phenomena. Therefore, they were practically not studied in this context. The results obtained indicate that anthropogenic pollution of the atmosphere and the impact of this pollution on the weather and climate is manifested even where people are not active. Indeed, very small aerosol particles due to their exceptionally low weight can be carried over greater distances than large ones.
