Some time ago there was a post on HN about one scientist who made a simple organism to grow two heads by messing with the intercellular magnetic fields. No DNA changes, just magnetic fields.

There's a way to check this hypothesis without cutting fingers. Salamanders can regrow tails. So get a salamander, cut its tail, use some magnetic field generator to mess with the regrowth process and see what happens.

The scientist is Michael Levin and his work, while absolutely legit, is so far from current mainstream that I am a bit afraid it might not be adapted for medical use in our lifetimes. Or possibly only after a major upheaval, much like mRNA deployment was accelerated by Covid. (mRNA co-pioneer Dr. Katalin Karikó ran into similar problems - the concept of mRNA was too revolutionary to be fully grasped by the PennU administration.)
