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 Quantum radio receiver will pick up the weakest signals
24.03.2019
Weak radio signals aren't just a problem for people trying to tune in to their favorite radio station, it affects magnetic resonance imaging technologies used in medicine, radio telescopes peering into the depths of the universe, and more. In all such cases, it is impossible, after suffering for some time, to tune in to another radio station, as in the first option, therefore, special amplifiers are used to amplify weak signals, the capabilities of which are limited by the magnitude of their own noise and which amplify these noises as well as a useful signal. But recently, researchers at Delft University of Technology, the Netherlands, have created a new type of radio receiver that uses the laws of quantum mechanics. In addition to the practical application of this receiver to receive the weakest signals, the principles used in it can shed light on the interactions between quantum mechanics and gravitational forces.
One of the tenets of quantum mechanics used in the new receiver is that energy can be transferred in tiny fixed "doses" called quanta. "Imagine that you are swinging a child on a swing," says Mario Gely, lead researcher, "From the point of view of classical physics, if I want to give the child more speed and swing amplitude, I will have to give them a push that Quantum mechanics says something else - I can only increase the child's energy by one "quantum step" at a time, transferring energy to him in the amount of half a quantum or another fractional part is fundamentally impossible.
In real life, these quantum "doses" of energy are so small that they will not have any tangible effect on a child on a swing. And until recently, such a statement was considered true in relation to radio waves. However, a new receiver can "feel" these tiny particles of energy in radio frequency signals, allowing it to receive radio waves at the quantum level.
The new receiver exhibits some unusual effects related to quantum mechanics and concepts such as mass and gravity. The theory of quantum magnetism was developed almost 100 years ago, but physicists are still puzzled by the problem of combining quantum mechanics and the concept of gravity.
