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. ... >>

Butterfly wings cooling 23.02.2020

In order to take off, a butterfly literally needs to warm up: if its muscles are not warm enough, they simply cannot contract at the speed that is needed for flight. Therefore, if the butterfly is too cold - for example, after a cold night - it crawls out into the sun and warms itself. But after all, not only her pectoral muscles are heated, but her whole body, and the wings too, and the wings heat up faster than the muscles. And it may happen that by the time the muscles are ready to take off as they should, the wings will be overheated.

Although the wings of butterflies seem to us inanimate - in the same sense in which bird feathers or our nails are inanimate - they still have areas of living tissue: these are the vessels penetrating the wing, through which the hemolymph (an analogue of blood in insects) flows, and the so-called androconia are groups of specialized scales that evaporate pheromones. Overheating for living areas of the wing would be inopportune. But butterflies have some tricks that allow them to cool their overheated wing.

Researchers from Columbia University, together with colleagues from other scientific centers, developed a special method with which it was possible to evaluate the heat radiation at different points of the butterfly's wing (a conventional infrared camera was not suitable here - it could not even distinguish the heat radiation of the wing from the heat radiation of the background). The new method was tested on 50 species of butterflies, and it turned out that the living areas of their wings are covered with special tubular nanostructures that serve as a kind of radiator; in addition, both vessels and odorous areas carry a thicker layer of chitin, which also helps to dissipate heat.

Some butterflies also showed an additional cooling system: for example, the male pigeons Satyrium caryaevorus and Parrhasius m-album have a vascular structure in their wings that pumps blood through odorous organs - these vessels contract several tens of times per minute. Such a pseudo heart in the wings makes them heavier, but the butterflies are apparently ready to put up with the extra heaviness in the wing, just to keep it from overheating and not letting their own source of pheromones deteriorate.
