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. ... >>

First successful robotic liver transplant 19.07.2023

Transplant surgeon Dr. Adil Khan and his team performed the first robotic liver transplant in the US at Barnes-Jewish Hospital. Now this innovative procedure is planned to be introduced in other clinics.

A 60-year-old patient suffering from liver cancer and cirrhosis caused by hepatitis C underwent a successful operation using advanced robotic equipment, while the chief surgeon controlled the operation from a nearby console.

"The transplant was a success: the new liver began to function immediately and the patient made a full recovery without complications," said Dr. Adil Khan, who led the surgical team from the University of Washington School of Medicine at Barnes-Jewish Hospital.

The recipient felt comfortable and regained mobility within a month after the operation, expressing a desire to return to golf and swimming. It usually takes about six weeks to recover from such an operation.

The hospital has focused on developing cutting-edge technology to minimize the invasiveness of operations and speed up patient recovery. Surgeons have already successfully completed more than 30 kidney transplants and other bile duct, pancreas and stomach related procedures using the robotic system. However, this operation was the first robotic liver transplant in the United States.

Liver transplantation is one of the most complex abdominal surgeries. Usually, the surgeon needs two incisions - 10 and 40 cm. However, in this case, the surgeons managed to get by with only 1,5 and 15 cm incisions.

The duration of the operation was a little over eight hours, but surgeons believe that the time of the operation will decrease as the procedure becomes more widespread and improved.
