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. ... >>

Radiation vs arrhythmia 27.09.2019

Researchers from Washington University in St. Louis found that high doses of radiation literally help patients with ventricular tachycardia survive.

With ventricular tachycardia, the heart ventricles begin to beat very quickly and without connection with the atria - the overall heart rate breaks up, and as a result, the heart simply cannot pump blood efficiently, because this requires the coordinated work of all heart chambers. Ventricular tachycardia easily leads to death, and to prevent this from happening, patients are usually implanted with defibrillators that bring the ventricles to life with an electrical discharge - but the tachycardia attacks themselves do not disappear from this.

But there is also a way to stop tachycardia altogether - when a catheter is inserted into the heart to intentionally damage the part of the heart muscle that generates seizures. After damage, the heart muscle begins to heal, and a small scar forms in it. In a "scarred" heart, irregular accelerated impulses can no longer spread through the ventricle and take it out of the general rhythm. However, this method often does not give lifelong relief from tachycardia, and, moreover, requires a long heart operation.

The same therapeutic injury can be done not with a catheter, but with a radiation beam directed exactly at the problem area of the heart muscle. Where exactly this problem area is located is determined using an electrocardiogram and computed tomography. No surgery, no anesthesia, or even hospitalization is needed - the radiation beam is directed to the desired area for 10 minutes, after which the patient can go home.
