Energy-dependent physical and biophysical constraints (7)

See first: Energy-dependent physical and biophysical constraints (6) Stems Cells in the Hypothalamus Slow Aging in Mice My comment to The Scientist Cai says microRNAs could be a potential mechanism by which hypothalamic neural stem cells have such wide-ranging effects on aging, yet he believes that neurogenesis may also be involved.

See: Feedback loops link odor and pheromone signaling with reproduction My comment to The Scientist: …trans-4-hydroxy-L-proline (Hyp) dehydratase, a newly discovered member of an abundant family of proteins, produced by gut bacteria, known as the glycyl radical enzymes, helps in metabolizing trans-Hyp, an…

Energy-dependent physical and biophysical constraints (2)

Summary: The mind does not exist in nature. It is a manifestation of how ecological variation must be linked to the creation of food energy-dependent pheromone-controlled ecological adaptations. Energy-dependent physical and biophysical constraints (1) The energy-dependent de novo creation of all receptors is biophysically constrained. See: Channel opening and gating mechanism in AMPA-subtype glutamate receptors This was reported as: Scientists capture first image of major brain receptor in action Defects in glutamate receptors, or the processes they mediate, are implicated…

Cell type assembly and the space-time continuum

Summary: The time to adopt energy-dependent cell type assembly as the unit of cognition was in 1944, when Schrodinger published “What is Life.” By the time Roger Penrose made his comment in the reprint edition, everyone else was too late. Penrose wrote: “How often do we still hear that quantum effects can have little relevance in the study of biology, or even that we eat food in order to gain energy?” (Roger Penrose 8 August 1991) See: Time (and space)…

Automagical disruption of an eQTL (2)

See: Automagical disruption of an eQTL (1) The automagical disruption of an eQTL, which linked rs34481144 and influenza could also have been reported in the context of this model. Nutrient-dependent/pheromone-controlled adaptive evolution: a model In the model, food energy links the pheromone-controlled physiology of reproduction in all living genera from rs34481144 and other SNPs to species-specific organism-level changes in skin, glands, and hair protection, which link ecological adaptations to protection from the virus-driven degradation of messenger RNA. Mathematical models vs. biological facts…

Richard P. Feynman refuted theistic evolution

Summary: Among other delightful examples of his expertise in physics, Feynman presciently linked natural selection for energy-dependent codon optimality from food energy-dependent pheromone-controlled biophysically constrained chromosomal rearrangements to healthy longevity. He also linked the radiation-induced theft of quantized energy to mutations in phages via amino acids that increase the virulence of the viruses. Updated information is presented in the context of refutations by many others who might otherwise claim to believe in theistic evolution. The miR-23a~27a~24-2 microRNA cluster buffers transcription…

Epigenetic effects of stress by Bruce McEwen (2)

Summary: …rapid mRNA turnover starts with the energy-dependent de novo creation of microRNAs and ends with the virus-driven degradation of messenger RNA, which links mutations to all pathology.   This was reported in the following context: “RNA molecules live short lives” July 12, 2017 See also: Epigenetic effects of stress by Bruce McEwen (1) Summary: In the early 1990’s, Bruce McEwen inspired my life’s works, which link the epigenetic effects of nutrient-stress and/or social stress to the fact that RNA biosynthesis…

God’s shrinking role in salvation (3)

Summary: I believe there is a bipartisan trend that links conservative Republicans to survival of the species, but I don’t know for sure what will happen to the liberal Democrats. And, I can’t prove it!   Helicity and chirality https://www.facebook.com/ed.unverricht/videos/10155506720828729/ See also: God’s shrinking role in salvation (2) A Theory of Reality as More Than the Sum of Its Parts “Causal emergence is a way of claiming that your agent description is really real,” said Hoel, a postdoctoral researcher at…
