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. ... >>

Stem cells have been trained to produce insulin 27.01.2019

UC San Francisco turned stem cells into functional beta cells that can produce insulin on their own.

Type 1 diabetes occurs when the body loses its ability to produce insulin on its own. This, in turn, is a consequence of the destruction of the immunity of pancreatic cells, and therefore patients have to regularly do all the "work" for them and manually inject themselves with the required hormone. In general, they can lead a full life, but they have an increased risk of developing kidney failure, heart disease, stroke, and a number of other pathologies. Yes, sometimes insulin therapy is replaced by the implantation of new beta cells - but this is a rare resource that requires donors.

To solve the problem, researchers have been working for a long time to turn stem cells into full-fledged pancreatic beta cells, but the task was not an easy one. "The cells that we and other researchers created were immature - and therefore could not properly respond to blood glucose and did not produce insulin," explains Herbock.

The solution came when scientists decided to implant stem cells directly into the pancreas. As a result of this process, the stem cells did not merge with native tissues, but formed a kind of protrusion - "islands" of the pancreas. The team examined them in a petri dish, artificially increasing the number of such clusters. As a result, pancreatic cells matured and functioned just like regular insulin-producing cells!

When these cells were transplanted into mice for testing purposes, the results exceeded all expectations: in just a few days, the artificial stem culture became involved in metabolic processes and began to produce insulin in response to changes in blood sugar levels. However, it is too early to talk about universal therapy: the study is still ongoing, and scientists fear that if a diabetic is transplanted with a culture, his immune system will simply destroy them. Thus, in order to live without diabetes, patients will have to take immune-suppressing drugs for life.
