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. ... >>

Brain training leads to the formation of new nerve cells 31.10.2023

German scientists from the Max Planck Institute for Cognitive Psychology and Neurophysiology in Leipzig conducted a study that reveals that brain training stimulates the formation of new nerve cells. This discovery aims to give hope to patients suffering from neurological disorders.

In the current study, researchers examined the effects of two different types of brain-computer interfaces (BCIs) on a major organ of the subjects' central nervous system. The volunteers were divided into groups. The first group's task was to imagine moving their arms or legs, which activated specific areas of the brain. Other participants were given tasks involving the visual cortex: recognizing and selecting letters on a screen. Studies were conducted before and after experiments using magnetic resonance imaging (MRI).

The results showed that the visual tasks performed well initially but did not improve with further training. In contrast, manipulation of the brain's motor system resulted in changes in areas used for related tasks, both visual and motor.

"Intensive training affects brain plasticity, the ability of the brain organ of the central nervous system to change depending on use. This means the possibility of both functional and structural changes. The latter relate to changes or even the formation of new nerve cells. Thus, we can conclude: training the brain leads to the formation of new nerve cells,” the scientists concluded.

The therapeutic potential of this method will be explored in subsequent studies. The question remains whether these changes will occur without feedback through the BCI system.
