Synthetic biology synthesizes viruses till 2002, bacteria in 2010, ribosome in 2013. Inevitably approaching the possibility of synthesizing a cell from single molecules, when it could use mirror-image molecules instead (enantiomers), getting mirror-chiral version of an organism, which among others would feed with L-sugars instead of our D-sugars ... and would be incompatible with our pathogens. Some potential applications: - mass production in e.g. chiral E. Coli of enantiomers of our proteins, opening new world of possibilities e.g. for drugs, - designing and creating bottom-up really sterile ecosystems, what might be essential e.g. for bringing life to harsh environments like Mars – pathogens greatly decrease efficiency of ecosystems and it seems impossible to really get rid of them in standard way, - finally to create chiral humans – immune to nearly all diseases. As it seems synthesizing some mirror-chiral organism is a matter of time, for example just because we can, let us try to prepare: discuss, understand its possibilities, consequences ... and dangers.
