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 ... >>

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. ... >>

Genetically modified maggots heal wounds 19.05.2016

Scientists at the University of North Carolina once again remembered the old method of treating wounds. They genetically modified the larvae to clean human wounds and secrete a reagent that accelerates healing.

In the past, doctors used carrion green fly larvae as a treatment tool. The larvae ate the dead tissue and left the living tissue, moreover, they secreted antimicrobial substances that kept the wound clean. In general, the method was cheap and effective, but not fast. Clinical trials have shown that maggots do not speed up wound healing, but new genetically engineered creatures could change that.

Human platelet growth factor is a signaling molecule that causes cells to divide rapidly. Also, as experiments have shown, it helps wounds heal. Researchers have already used insects to produce growth factor, but the technique has never been used on fly larvae. Biologists from North Carolina made two "batches" of larvae. One was modified to produce a factor when heated to 37 degrees Celsius. The other produced the necessary substance if she followed a diet that did not include the antibiotic tetracycline.

The heated larvae really began to produce a growth factor, but they never isolated it from their bodies, but a group of larvae purified from tetracycline abundantly excreted the required substance in body secretion and waste products. Although the larvae have not yet been tested on human wounds, the researchers believe that these insects will both clean wounds and heal them, greatly reducing the time it takes for flesh to heal.

Such a remedy will especially help people with diabetes who have non-healing ulcers on their legs. Although the thought of worms poking around in open wounds is unpleasant, but if they halve the healing time, then the remedy will be popular.
