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 ... >>
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 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. ... >>

Laughing depends on the genes
16.06.2015
Why does someone barely smile at the same joke, and someone starts laughing until they drop? Of course, a lot here depends on personal taste and culture, but not only - according to researchers from Northwestern University, some people have their own genetic characteristics that make them very funny.
It is known that our emotions and mood are largely dependent on the level of the neurotransmitter serotonin - for example, a chronic lack of serotonin can lead to constant anxiety and depression (which are within easy reach of the abuse of various "substances"). Serotonin levels are controlled by the 5-HTTLPR gene, which has a long and a short version. At one time, it was shown that it is the short version of 5-HTTLPR that can be found in people prone to gloomy thoughts and depressive states.
However, as Claudia M. Haase and her colleagues found, short 5-HTTLPR is also associated with increased laughter. They set up several experiments, showing funny videos to people of different ages; in addition, in one of the experiments, older couples had to discuss the difficulties of their own marriage. All this was recorded on camera, after which facial expressions were evaluated using a special system that makes it possible to distinguish natural positive emotions from artificial ones, when a person laughs or smiles out of politeness or, for example, to hide negative emotions. (In particular, "crow's feet" around the eyes are considered one of the reliable signs of a real smile.) The emotions were then compared with data on the 5-HTTLPR gene.
According to the authors of the work in the journal Emotion, the owners of the short version laughed and smiled more readily than those whose 5-HTTLPR was long. That is, humorousness really partly depends on genes. However, something else is more curious: it turns out that the same gene can affect both positive and negative emotions.
For the researchers themselves, the results were not such a surprise. Although, as we said above, the short version of 5-HTTLPRR was originally considered to be an enhancer of depression, then works began to appear that said that positive emotions cannot do without a shortened version of the same gene. According to Claudia Haase, a short 5-HTTLPR cannot be considered either "fun" or "sad" - it only enhances the emotional response to certain circumstances: if everything is good, it will help a person to rejoice, if it's bad, on the contrary, plunge into depression. As for those who got a long 5-HTTLPR, they simply perceive everything less emotionally, and their experiences, whether joyful or not, devoid of a genetic "amplifier", remain quite moderate. It is not known which is better; but at the very least, if you're depressed, it's worth considering that it's actually not all that bad, it's just that you were unlucky with the gene that controls serotonin.
