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. ... >>

Clean energy from the air 19.03.2023

Scientists have discovered that one of the "relatives" of the tuberculosis bacterium is an enzyme that converts hydrogen into an electric current.

The researchers believe that the discovery can be used for a new way to get energy from the air. This is Mycobacterium smegmatis, a bacterium that uses the Huc enzyme to generate energy from hydrogen in the atmosphere, allowing it to survive in extreme nutrient-deficient environments.

The scientists said they had discovered and studied an enzyme that could be used as a source of clean energy to power laptop computers.

"We believe that a power source containing the Huc enzyme could power a range of small portable devices, including biometric sensors, environmental monitoring devices, digital clocks, calculators, and even simple computers," said study lead author Reece. Grinter, a microbiologist at Monash University in Australia.

It is a rapidly growing, non-parasitic bacterial substance that is often used to study the cellular structure of the causative agent of tuberculosis, Mycobacterium smegmati. This bacterium has been known for years to convert hydrogen into electricity. Scientists have found that it is able to survive in harsh weather conditions such as Antarctica, volcanoes and deep oceans, where there are very few other sources of energy.

“If you provide the Huc enzyme with more concentrated hydrogen, it will produce more electrical current. This means that the Huc enzyme can be used in fuel cells to power more sophisticated devices such as smartwatches or smartphones, more sophisticated laptop computers, and perhaps even cars.” "Grinter explained.

The scientists found a charged structure in the center of the Huc enzyme containing nickel and iron ions. When a hydrogen molecule enters the active zone, protons and electrons find themselves in a chain between nickel and iron atoms. The enzyme then sends the electrons to "conductive pathways" that conduct electrical current.

Experiments have confirmed that Huc is able to persist for a long time and can absorb hydrogen in a negligible concentration, which is 0,00001% of the volume of air inhaled by a person. The scientists believe that these properties, combined with the bacteria's omnipresence, could be ideal candidates for a clean energy source for organic batteries.
