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. ... >>

Found the relationship between attention to the child and his intelligence 06.08.2023

Comparing the IQ indicators of children living in a family environment and children who grew up in orphanages, scientists have identified significant differences in favor of the first group.

One of the important projects in this area, called the "Bucharest Early Intervention Project" (BEIP), was launched in the early 2000s. Its goal was to track the cognitive development of children raised in orphanages.

The researchers monitored brain activity in 202 children, including those who lived in institutions, adopted children, and children who grew up in a family setting.

Later, scientists from the US and Germany joined the study and identified several types of brain activity, the origin of which remains unclear. They have been classified into three categories based on the speed of the waves.

As study participants matured, it became apparent that those who had less slow brain activity as children showed higher levels of intelligence. This trend was more common among those who grew up in orphanages.

Scientists believe that slow wave activity is related to the level of attention given to a child at an early age. They also found a link between this activity and social status, as well as the financial situation of the family.

Further research is planned on a larger scale in order to identify new factors influencing the intellectual development of children. However, it can already be concluded that the results of the current study emphasize the importance of paying attention to children from a very young age for their future intellectual growth.
