Some genetic scientists have a conscience and common sense. Dr. Kate gave up her $1 million grant from the U.S. National Science Foundation when she realized how dangerous the research became. She said, "mirror cells would likely be completely invisible to the human immune system." The NSF came up with this stupid idea in the first place. Think about it: you ingest a harmful bacterial strain that is easily defeated by your immune system. But if its DNA is mirrored, your body will not even see it, and you could be dead in two days. ?

Scientist Kate Adamala doesn't remember exactly when she realized her lab at the University of Minnesota was working on something potentially dangerous — so dangerous in fact that some researchers think it could pose an existential risk to all life forms on Earth.

She was one of four researchers awarded a $4 million US National Science Foundation grant in 2019 to investigate whether it's possible to produce a mirror cell, in which the structure of all of its component biomolecules is the reverse of what's found in normal cells.
