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. ... >>
| Random news from the Archive 2000 atoms in two places at the same time
02.10.2019
A team of scientists from the University of Vienna and the University of Basel has tested the principle of quantum superposition on the largest scale in the history of science. Huge complex molecules, consisting of two thousand atoms, were placed in a state of superposition, while being in two places at the same time, according to the bizarre laws of quantum mechanics. This achievement is a weighty confirmation of the manifestation of superposition, which is the "heart" of all quantum technologies, which, in turn, serves as a serious limitation for the further development of many alternative theories.
We remind our readers that the principle of superposition is one of the main "pillars" of quantum mechanics, which is a consequence of one of the fundamental equations, the Schrödinger equation. This equation describes quantum particles by their wave functions, which are very similar to the functions that describe concentric waves on the surface of water. However, unlike waves on the surface of water, which are a manifestation of the collective behavior and interaction of many molecules, quantum waves can be associated with individual particles.
One example of the wave nature of quantum particles is an experiment with two slits located very close to each other, through which a "wave" of one particle simultaneously passes. After passing through the cracks, the waves are added to each other and the particle-wave again acquires its integrity. This effect has already been demonstrated for photons, electrons, neutrons, and even single atoms.
In their experiments, the scientists used the largest available molecule C707H260F908N16S53Zn4, which consists of a total of 40 thousand protons, neutrons and electrons, and has a mass equal to 25 thousand atomic masses. To synthesize such molecules, special methods were used that made these molecules stable enough to form a beam directed inside an ultra-high vacuum chamber. Verification of the quantum nature of such massive particles required the use of an interferometer, two meters long, which was at the disposal of the University of Vienna.
According to one of the alternative theories, which serves as a kind of bridge between classical physics and quantum mechanics, the duration of the dominance of the wave function of a particle decreases in direct proportion to the mass of this particle. This, in turn, also limits the time the particle stays in the quantum superposition state.
In their experiments, scientists found that huge molecules were in a state of superposition for 7 milliseconds of time, long enough to leave no stone unturned from the above theory and from a number of other alternative theories and models.
