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. ... >>

Closest pair of stars in binary system discovered 18.03.2019

Scientists have discovered a binary system with the closest pair of high-mass young stellar objects ever studied. This provided them with a valuable "laboratory" for testing theories about the formation of massive binary stars.

An international team of astronomers led by the University of Leeds has determined the shortest distance between the young massive star PDS 27 and its massive companion: just 30 astronomical units (AU), or 4,5 billion kilometers. This is about the same distance that will separate Neptune from the Sun. Thus, today this pair of stars is at the closest distance in a binary system.

As part of the study, the team also identified a companion of another massive star, PDS 37. The analysis showed that the distance between PDS 37 and its companion is somewhere between 42 and 54 AU, which is comparable to the distance from the Sun to Pluto. Even though this pair is further apart than PDS 27, it is still an important discovery given the need for confirmed massive young binary star systems in astronomical research.

PDS 27 is at least 10 times more massive than the Sun and is eight thousand light-years from Earth. To determine the presence of stellar companions PDS 27 and PDS 37, the team used the highest spatial resolution of the PIONIER telescope instrument at the European Southern Observatory. This instrument combines the light beams of four eight-meter telescopes and simulates one telescope with a diameter of 130 meters. The resulting high spatial resolution allowed the team to view such close binary systems, despite their distance from us and close to each other.
