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. ... >>

Nanospaghetti for health and longevity 10.04.2012

The 243rd National Meeting of the American Chemical Society unveiled the latest technology in regenerative medicine that can address the many ailments of old age and the effects of trauma. Unique nanofibers, developed by a team of scientists led by Dr. Samuel Stapp, can improve the physical abilities of the elderly and victims of accidents. The fibers are similar to raw spaghetti, but only microscopic in size. This is a new word in regenerative medicine, the main task of which is the repair or replacement of damaged organs: from the cartilage of the joints suffering from arthritis, to the nerve nodes torn in a car accident.

Regenerative medicine is relevant today more than ever. There are more and more older people in industrialized countries, and many of them are very valuable professionals. The tasks of health care include maintaining the working capacity of older people, prolonging their lives and getting rid of senile diseases. In addition, there are many people with severe injuries, complications due to chronic diseases, etc., which also requires the efforts of regenerative medicine.

"Nanospaghetti" can become one of the most valuable tools of regenerative medicine. These are small fragments of proteins that stick together randomly. The fibers are so small that over 50 fibers are the width of a human hair. "Nanospaghetti" can perform many functions. For example, Samuel Stapp attached signal molecules to them that mimic the substance VEGF, which promotes the formation of new blood vessels.

In mice, VEGF has successfully grown new blood vessels to replace damaged ones. Unfortunately, human experiments with VEGF ended in failure due to the fact that this substance is quickly broken down in the human body. At the same time, the new nanofibers remain inside for a week, allowing the VEGF analog to grow vessels. As a result, after dissolving the "nanospaghetti", only freshly grown fully functional blood vessels remain.

"Nanospaghette" can not only mimic the action of VEGF, they have a potential solution to many problems in regenerative medicine. In particular, this is the delivery of proteins, biological signals and stem cells to a specific point in the body, for example, to a damaged part of the heart, brain, spinal cord or other organs. Also, the new nanofibers can "line up" stem cells in the right order for proper repair of damaged tissues.
