Let there be anti-entropic light (1)

terrarium eco system

Summary: Light-induced amino acid substitutions link cell type differentiation in plants to nutrient-dependent pheromone-controlled reproduction in animals via the biophysically constrained chemistry of protein folding. Protein folding is perturbed by mutations that limit the ability of organisms to adapt to…

Physicists: Desperate Acts

Light induced conformer intercoversion of hydrogen bond

Participation on the FB group Thinking Allowed Original led to an invite by Ulla Mattfolk to participate on her secret group  Quantum Biology, coherence and decoherence. On January 22 at 11:45pm, discussion led me to ask whether biophotonic energy differences could be recognized by the photons at…

Environment epigenetically shapes the immune system

human-evolution

Environment, more than genetics, shapes immune system 1) –with my emphasis Re: “There’s nothing here that is revolutionary or requires rethinking of our assumptions about how the immune system functions…” My comment: They removed assumptions about cell type differentiation by…
