Quantum entanglement, mass, and biomass

achiral glycine

Joseph Kover seems closer than most other physicists to linking light-induced amino acid substitutions to cell type differentiation and biomass via the biophysically constrained chemistry of protein folding.  Today he posted notice of the following publication with the comment: “……
