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. ... >>

The main molecule of the Universe is determined 27.04.2012

Scientists from the University of Arizona have found that the molecular hydrogen ion H3+ is the main molecule in the universe. It is thanks to H3 + that the formation of stars and the development of the universe in the form that we know became possible.

Most of the universe is made up of hydrogen in various forms, but the H3+ ion is the most abundant in interstellar space. It turns out that this is one of the most important molecules, playing a key role in the cooling of the first stars. H3+ was crucial in the formation of stars in the early days of the universe. According to Professor Ludwik Adamowicz, H3+ is a precursor to many types of chemical reactions that make it possible to obtain, among other things, compounds necessary for life, such as water or carbon.

If not for H3+, the early stars would gradually get hotter and eventually explode. We might never see the starry sky, and we ourselves would not exist. H3+ molecules were the only way to dump the extra energy of young stars and prevent them from exploding.

Stars could not form and burn steadily for billions of years if it were not for the molecules that slowly cool the stars by emitting light. Few molecules are capable of doing this, but in the early days most simply didn't exist, and this is where H3+ played a key role.

Ordinary hydrogen "does not like" to emit light, while H3+ is an electrically charged molecule composed of three hydrogen atoms with two electrons. It is because of the lack of one negatively charged electron that the H3+ molecule acquires a positive charge. This makes it vibrate, emitting light. Thus, the release of excess energy of the star and its cooling.

Thanks to the study by American scientists, astronomers now know more about the formation of young stars and the early Universe and can more accurately determine the composition of space objects. Ultimately, this will lead to an improvement in the model of our Universe.
