What is cloning?

In a narrow sense, cloning is the production of copies of cells, genes, antibodies and multicellular organisms in the laboratory. To do this, DNA is extracted from the original organism, a copy of which is desired to be obtained, and inserted into another egg. Further, this egg is implanted in the uterus of the future parent ("surrogate mother"), and as a result of a normal pregnancy, a copy of the original is born. An example of this is the world-famous Dolly the sheep.

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 ... >>
