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. ... >>

The distance of ultrashort flashes of light is calculated 06.11.2021

Researchers at the American University of Beirut tracked the dynamics of two linked flashes of light in real time. Distances can be predicted based on differences in transit times within the resonator and fine-tuned by shifting the optical elements. Scientists have proven that it is the optical reflections inside the laser cavity that connect the solitons in time and space.

The study showed how the link between two outbreaks weakens, and then a new link is quickly created between them. Now you can specifically switch between flashes of light that occur in pairs and have different time intervals. Therefore, it is possible to generate coupled flashes of light in other laser systems and switch their distances without much effort.

"Switching soliton molecules with a single button opens up new perspectives for technical applications of femtosecond pulses, especially in spectroscopy and materials processing," says Luca Nimmesgern, first author of the study and a master's student in physics at the University of Beirut.

Since the first reports of pulse pairs in fiber lasers more than 20 years ago, there have been many different explanations for the stability of soliton molecules in lasers. A new study offers the first definitive explanation compatible with measured data.
