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. ... >>

Bacterial ink for 3D printer 13.12.2017

3D printing technology allows the use of a variety of substances as "ink". Indeed, in recent years, everything has been loaded into XNUMXD printers, ranging from ingenious thermo- and light-sensitive polymers, from which objects are made that change shape when temperature or light changes, and up to proteins, from which semi-synthetic organs are created.

Moreover, from time to time, researchers try to print something directly from living cells. But so far, cell printing has not advanced far, for the simple reason that our cells, which are protected from the external environment by only a two-layer lipid membrane, do not withstand the conditions of the method and die.

But what if we take not human and animal cells, but bacteria? After all, in addition to the membrane, they also have a fairly powerful cell wall, and in general, bacteria are not as sensitive to extreme influences as eukaryotic cells, so it is quite possible that they will easily survive a 3D printer.

To print with bacteria, they need to find an environment in which they could live, being applied to the surface. In a bacterial "ink" created by scientists at the Massachusetts Institute of Technology, a pluronic acid-based hydrogel was made as a carrier for bacteria: such a hydrogel retains water with nutrients, allowing cells to live and function, and is quite suitable for a 3D printer.

Before the experiment, the bacteria underwent genetic modification, which made them sensitive to a particular substance: if the desired substance appeared in the medium, the bacteria synthesized a fluorescent protein. Then, using a 3D printer, a tree-like pattern was printed on a special elastic material, consisting of three types of bacteria that react to three different substances (it is clear that the printer allows you to mix and alternate "ink" as we please). The resulting pattern was glued to a human hand, which had previously been moistened with a solution with three types of signal molecules - and as a result, the pattern on the hand began to glow: different bacteria each felt their own substance and made a fluorescent protein in response.

Bacterial "3D ink" allows printing at very high resolutions of up to 30 micrometres, which in turn is suggestive of bacterial microcircuits, in which groups of bacteria perform logical operations, similar to microcircuits in a computer.
