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. ... >>

3D printed squid rings 14.08.2023

A team of scientists from the National University of Singapore has developed a method to create food equivalents of squid rings using a 3D printer. These analogues have a high protein content, as well as appearance and taste reminiscent of real squid rings.

This innovative approach will produce squid rings that are similar to the original in both texture and taste, making them suitable for consumption.

The project was developed in response to current environmental challenges associated with the overfishing of the world's oceans, as well as the growing interest in alternative sources of seafood that do not harm the environment. In addition, wild seafood often contains harmful substances such as heavy metals and microplastics.

However, creating plant-based food products that match the taste and nutritional profile of seafood has been a challenge. Already existing vegetarian analogues often did not have sufficient protein content. The researchers decided to use an innovative method - a 3D food printer.

"Our approach was to create protein-based seafood analogues that would not only be nutritious, but also have similar taste characteristics to the original products. We also paid special attention to the environmental component of this method," said Dejian Huang, principal investigator of the project.

With the help of a 3D food printer, it was possible to accurately reproduce the structure of fish meat. The process of applying edible materials to the surface in layers has made it possible to create different textures - from greasy and smooth to fibrous, combined in one product.

“We created salmon fillets from red lentil protein to achieve a similar color and taste. We also produced shrimp. However, we are particularly proud of squid rings, an interesting and potentially commercial product,” added Huang.

Researchers have prioritized sustainable and nutritious protein sources such as microalgae and mung bean to create these squid ring food alternatives.
