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. ... >>

Mosquitoes fly to the voice 19.02.2019

Mosquitoes rely on sight and a keen sense of smell to find potential food sources and mating partners. However, until now it was believed that these insects do not hear very well. “Previous experiments have shown that males are only attracted to the sounds of a female flying in close proximity,” says Cornell University professor Ron Howe. “This supported the idea that they are only able to hear something very close to them, at a distance of up to 30 centimeters.” .

Professor Howe's team had already studied the auditory neurons of spiders - the methods used then were suitable for insects. This time, scientists looked at Aedes aegypti mosquitoes, carriers of many viruses dangerous to humans. Already the first experiments in the laboratory showed that the auditory nerve cells of mosquitoes react to sound from the opposite side of the room. Therefore, the experiments had to be continued in a specially built large anechoic chamber.

Female mosquitoes buzz at a frequency of 400 Hz, and when the biologists reproduced this sound, the males immediately reacted and flocked from a distance of up to three meters. "The sensitivity of males was so high that we ourselves could hardly hear this sound, while we clearly saw that mosquitoes hear it," the researchers say.

They found that mosquitoes - even without our hearing aids - could distinguish between 150 and 500 Hz. The human hearing range is 20-20 thousand Hz, but speech, as a rule, sounds in the range from 150 to 900 Hz, being perfectly audible for mosquitoes. In addition, the sensitivity of mosquitoes allowed them to hear sound up to 30 decibels - significantly lower than the usual voice power when talking (45-70 decibels). However, the authors acknowledge that the ability of mosquitoes to hear our voices does not mean that they really use it in search of victims.
