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. ... >>

Keychain activates the immune system 14.07.2012

In search of a flu vaccine, researchers at San Diego State University and the University of Nebraska have created an artificial protein that activates the body's immune system just two hours after injection.

Initially, scientists thought that the EP67 protein would be an adjunct to allowing the vaccine to boost the immune response. Then it turned out that he could work independently, and in some respects better than the vaccine itself.

"The flu virus is very insidious," says Joy Phillips of San Diego, who, along with colleague Sam Sanderson, published the results of the study in the public scientific library journal PLoS ONE. "It hides from the immune system skillfully for several days until symptoms of the disease appear. Our research has shown that injecting EP67 into the body within 24 hours of infection activates the immune response to a threat almost instantly, before you feel sick."

The peculiarity of the EP67 protein is that it is not designed for any particular strain of the influenza virus, but simply activates the immune system. According to Phillips, the protein could have dealt with both SARS and the 1 H1N2009 virus epidemic. In her opinion, he is able to defeat a respiratory disease or a fungal infection, the main thing is to feel the threat in time and introduce protein into the body. So far, EP67 has only been tested on mice infected with the common flu. Animals that were injected in the first 24 hours after infection, in contrast to the control group, had the flu in a very weak form.

The degree of mouse disease is determined by weight loss. Usually, having caught the flu, the mouse loses about 20% of its body weight - and this is exactly how the representatives of the control group "behaved". In turn, after the injection of EP67, the animals "lost" only 6%. In addition, it is very important that mice that received a lethal dose of the virus and then EP67 did not die.
