content: 2. -Maurizio Menicucci: the debate on the risks of research is as old as science and at the bottom is the myth of falling icarus for having touched the sun with the wax wings designed by his father. An experiment carried out in China  where a group of scholars has managed to develop a chimera, a modified organism by inserting the surface protein of a coronavirus found in bats of the species common called Horseshoe, on viruses that cause sars acute pneumonia, although in a non-fatal form in mice. It was suspected that the protein could make the hybrid suitable for affecting humans and the experiment confirmed it and precisely this molecule called SHC014  that allows the coronavirus to attach itself to our respiratory cells and triggering the syndrome.
