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 Music tunes the child's brain for speech
28.04.2016
You cannot confuse ordinary speech with music, they are still quite different, but they have something in common, and this is common - rhythmic organization. Musical rhythm is quite an obvious thing, but speech sounds are not at all chaotic, they are distributed over syllables and words, and when we hear someone say something, we clearly feel the boundaries between syllables, words, parts of a sentence, which allows us to understand what we hear.
In addition, according to some sources, the language in general is very deeply connected with music and even largely determines the structure of not only folk melodies and rhythms, but even author's musical works.
But if there is so much in common between music and speech, can we improve speech understanding with the help of music? Psychologists from the University of Washington think we can - experiments have shown that musical exercises help tune the brain to language. The experiment itself looked like this: for thirty days, parents with nine-month-old babies regularly came to the laboratory to play with their children for 12-15 minutes under the supervision of researchers. In one group they played with ordinary toys - with cars, dolls, cubes, and in the other they played musical games in which it was necessary to follow the rhythm (moreover, the music was in the rhythm of a waltz, which was not easy for young children to follow).
A week after the games were over, the parents and their children returned to the lab, this time using magnetoencephalography to determine the activity of different parts of the brain in infants. Sitting in the scanning device, the children listened to musical or speech fragments, and the rhythm of both speech and music was broken from time to time.
In the PNAS article, the authors write that those who played music games had a stronger brain response to rhythm disturbances - this was seen in the activity of the auditory cortex and in the activity of the prefrontal cortex, which, among other things, controls attention and the ability to sense structure in that we perceive.
If the brain feels interruptions in the rhythm, it means that in principle it heard it, learned it - otherwise it would not feel any changes. Of course, after musical games, one could expect that children would begin to perceive music better, but, as we see, the matter was not limited to music, as a "side effect" the brain began to respond more actively to the speech structure.
