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. ... >>

Stem cells cured the brain 23.10.2012

Scientists and neurosurgeons from the University of California (UCSF), San Francisco, have performed a stem cell operation that has helped cure the most severe and incurable brain disease. Operations were performed on four boys with a rare fatal brain disease - Pelizeus-Merzbacher disease. In the human brain is a special substance - myelin, which surrounds the nerve fibers. Without myelin, the transmission of electrical impulses along the nerve fibers is impossible, and the signals in the brain become scattered and disorganized.

Most babies are born with very little myelin, which develops throughout life. In children with Peliceus-Merzbacher disease, a genetic mutation interferes with the production of myelin, causing the electrical signals to fade before they reach their destination. This leads to serious consequences for the development of the child: he cannot learn to walk, talk, and, ultimately, premature death occurs.

American scientists for the first time tried to cure this disease using the latest technology. Scientists have successfully transplanted human neural stem cells into white matter deep in the frontal lobes of the brain.

Twelve months after the operation, the boys showed an increase in myelin, resulting in markedly improved brain function. Three out of four boys began to experience developmental shifts, for example, the oldest, 5-year-old, was able to eat on his own for the first time and walk with minimal help from adults. However, no serious side effects, such as the development of tumors, were observed in any case.

So far, this is just an experiment that requires further development. However, the resounding success of successfully transplanting neural stem cells into the brain paves the way for the development of new super-efficient methods for the treatment of severe congenital diseases and very common ailments such as Parkinson's disease and multiple sclerosis.
