What is #MirrorLife? Scientists have issued warnings about the potential dangers of organisms made from #MirrorImageMolecules. A #MirrorCell, in which the structure of all of its component biomolecules is the reverse of what’s found in normal cells. Such #ReversedCells, which have never existed in nature, could shed light on the origins of life and make it easier to create molecules with therapeutic value, potentially tackling significant medical challenges. In nature, the structure of many major biomolecules is right- or left-handed, although it’s not clear why life evolved this way. DNA and RNA are made from “right-handed” nucleotides, and proteins are made from “left-handed” amino acids. But mirror cells would likely be completely invisible to the human immune system. Because #NaturalLife-is-#Chiral, interactions between natural organisms and mirror bacteria would be profoundly unpredictable. Ultimately, it might act like an invasive species, disrupting ecosystems without predators to keep it in check. Mirror cells could become a reality in the next 10 to 30 years with potentially #DevastatingConsequences, if mirror bacteria were released into an environment and spread, evading natural biological controls and acting as dangerous pathogens. https://t.co/wYNLw1ZVYF
