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. ... >>

Barrier Key 30.05.2015

The nanoparticle was able to open the barrier between the circulatory system and the brain.

The blood-brain barrier does not let potentially dangerous blood components into the brain: microorganisms, toxins, immune system factors. Unfortunately, he does not miss many medicines. Physicists from the University of Montreal, led by Ani-Sophie Carret, managed to find the key to the lock that closes the barrier. They turned out to be magnetic nanoparticles. So far, experiments have been carried out on moray eels, but there is hope in the near future to move on to experiments with people.

In one of the preliminary studies, scientists found that magnetic particles can be brought to the right place using a magnetic resonance imaging device. In the new experiments, nanoparticles were brought to a barrier separating the brain and blood, and then microwave radiation was directed at them. The particles warmed up and heated everything around them, which increased the permeability of the barrier. So it became possible to drag nanoparticles with medicine through it.

The authors of the work hope that in the future it will be possible to fine-tune the technique and bring these particles that have gone beyond the barrier to the desired part of the brain. So far, this requires surgery.
