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. ... >>
Random news from the Archive Mars and its volcanic past
01.07.2018
Everyone knows that Mars has the largest volcano in the known limits of the solar system - named after Olympus, this volcano, as it turned out, also contains the largest amount of volcanic deposits. However, this assumption remains so for the time being, however, some found and proven facts about the geography of Mars clearly indicate the realism of such a result. Experts have previously discovered the so-called Medusae Fossae rock formation, whose origin has so far remained the subject of much controversy for scientists - which today has been partially resolved in favor of the theory of the consequences of a volcanic eruption.
This is a fairly popular and most likely hypothesis about the origin of this rock formation within the equator of Mars - it covers approximately 2 million square kilometers and was first discovered back in 1963. Using combined imagery and radiographic evidence from different spacecraft near Mars, scientists have advanced the strong belief that the formation is predominantly composed of so-called soft rock, formed from 2/3 of the Martian surface and ice.
It is the discovery of ice there that indicates that this rocky ridge - like most of the territory of Mars - was the result of a massive and destructive volcanic eruption that occurred, according to preliminary estimates of experts, about 2 billion years ago. In addition, experts add that winds also mixed in here.
Thus, the previous theory that most of the surface of Mars was formed in this way due to a massive volcanic eruption seems to be confirmed by recent finds of a rocky ridge. It is also worth noting that scientists are still working on the ability to establish how accurate they are in their calculations regarding the layering of a rock formation - because a more detailed interpretation of its state will theoretically significantly enrich the understanding of the formation of planets and stars.
