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. ... >>

Electronic control of genes 25.01.2017

We usually don't like bugs and viruses in our digital gadgets, but that seems to be about to change. Scientists have found a way to control the genes of bacteria at the flip of a switch using electricity.

Synthetic biologists are happy to look for ways to connect modified organisms with electronics so that we have living devices and gadgets. The ability to create custom microbes to sense the environment and make biological molecules will be especially valuable for devices that will work inside our bodies, says William Bentley of the University of Maryland. For example, such a device could be used by a living organism to detect chemicals produced by disease-causing bacteria and to isolate the appropriate antibiotic.

In order for certain genes to respond to electrical stimulation, Bentley's team uses so-called redox signaling molecules. These biological molecules are found in all cells, and they are able to pick up and transfer electrons. The scientists also took advantage of natural genetic components in E. coli that respond to oxidative stress, which occurs when too many molecules in the body are oxidized.

To give an electrical charge, the researchers immersed the electrode in a liquid containing bacteria. When the electrode gives a positive charge, redox molecules are oxidized and trigger genetic mechanisms that respond to oxidative stress. With this procedure, Bentley showed how E. coli, when exposed to a discharge, float or begin to glow.

They also made a bacterium release a signaling molecule that makes another bacterium light up, thus showing that it is possible to design one set of bacteria to act on another set of bacteria when they are electrically discharged.

The procedure involves only a small "flashing" of bacteria with careful control of the process. For example, biosensors can be obtained in this way, where modified bacteria can recognize certain substances, for example, identify infections and respond with a glow. According to experts, it will take only a year or two to implement this technology, and then the procedure for merging biological and digital devices can be launched at full speed.
