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. ... >>

Hands help the musician remember the melody 26.10.2012

How do we remember a melody? And why does a pianist who forgets notes often start over? Scientists at Georgetown University Medical Center now know the answers to these questions. At the Neuroscience 2012 annual meeting of the neuroscience community, researchers revealed their findings on what the brain must do to process new musical sequences and how to recall them.

The answer, according to Brennon Green, a graduate student working in lead author Joseph Rauscheker's lab, is that two different areas of the brain are involved. One is to memorize a fresh sequence of notes, the second is to remember it later. But what is most surprising is that both use motor skills.

Green, Rausheker, and three colleagues at Aalto University in Helsinki used functional magnetic resonance imaging (fMRI) with volunteers listening to music directly in the scanner. The researchers found that the basal ganglia and cerebellum, areas of the brain responsible for movement, were activated to memorize music. It would be less surprising if these areas were used for singing - after all, it requires at least some muscular activity. These areas were active when people were trying to memorize notes, with one sound activating one neuron, another activating the next, and so on.

"The motor system includes some areas of the brain that nature has chosen to decode sounds. Therefore, in order to recognize a melody, the auditory system captures the musculoskeletal system," says Rauscheker .. "This is the same part of the brain that we use to learn to ski or dance," confirms Green.

After participants in the study recognized the sound of a melody, magnetic resonance imaging showed that brain activity switches from an area responsible for motor skills to an area associated with long-term memory. It also showed that it didn't matter exactly how many neurons fired to learn or remember a melody. Rauscheker likens the memorization of notes to dominoes stacked one after another: “In a melody, the tones are connected with each other in a certain order. And, as after the push of the first domino, the entire chain of dominoes falls one after another. Neurons are excited in the same way - one after another. way, it takes fewer neurons to remember a melody." This explains why it's easier to start over if you get stuck in the middle of a piano performance.
