Energy-dependent physical and biophysical constraints (5)

Summary: Emmy Noethe’s theorems were developed in the early 1900’s. Richard Feynman inadvertently or purposefully alluded to them as examples of human idiocy. Discover Magazine resurrected the examples of human idiocy in a 2017 article. For comparison, Choi et al., (2017) support the claims that intercellular and interkingdom communication is energy-dependent and controlled by the metabolism of food energy to pheromones. It is obvious that pheromones biophysically constrain the virus-driven degradation of messenger RNA. That fact links everything currently known…

Energy-dependent epigenetic translation to mRNA stability

Negative selection in humans and fruit flies involves synergistic epistasis Negative selection against deleterious alleles produced by mutation influences within-population variation as the most pervasive form of natural selection. Naturally occurring positive selection for energy-dependent codon optimality replaced every aspect of neo-Darwinian theories that linked natural selection from mutations to evolution of increasing organismal complexity. Positive selection for epigenetically-effected beneficial alleles links the epigenetic landscape to the physical landscape of supercoiled DNA via nutrient-dependent pheromone-controlled metabolic networks and genetic networks.…

Nutrient-dependent pheromone-controlled autophagy (2)

See also: Nutrient-dependent pheromone-controlled autophagy Autophagy: cellular and molecular mechanisms (2010) Conclusion: … autophagy has emerged as a new and potent modulator of disease progression that is both scientifically intriguing and clinically relevant. My comment: Autophagy is energy-dependent and linked to supercoiled DNA by epigenetic effects on the innate immune system, which are linked to the physiology of energy-dependent reproduction. If you think that the innate immune system automagically “emerged,” you might also think that autophagy has automagically emerged as the…

Nutrient-dependent pheromone-controlled autophagy

See also: Nutrient-dependent pheromone-controlled autophagy (2) The Excitable Mitochondria links 4 neurons from a nutrient energy-dependent pheromone-controlled network in a marine invertebrate to human brain development via the conserved molecular mechanisms that link the speed of light on contact with water to the de novo creation of G protein-coupled receptors (GPCRs).  Receptor-mediated species -specific chromatin remodeling links chromosomal rearrangements to all biodiversity via energy-dependent chemotaxis and phototaxis.

How did the innate immune system evolve?

Sexually Antagonistic Male Signals Manipulate Germline and Soma of C. elegans Hermaphrodites Abstract excerpt: Why would a system exist that reduces the vigor of potential mates prior to mating? Addressing this question could provide insights into mechanisms and evolution of sexual conflict and reveal sensory inputs that regulate aging. Highlights excerpt: An unknown signal accelerates larval development, specifically the onset of puberty Reported as: Male chemistry primes females for reproduction—but at a cost “There is a fine balance between reproduction and…

Models are not theories (2)

MicroRNA-encoded behavior in Drosophila Editor’s summary: MicroRNAs (miRNAs) are small non-coding RNAs that regulate gene activity. They repress expression through complementary base pairing interactions with target messenger RNAs. MiRNAs are involved in regulating many cell and developmental processes. Picao-Osorio et al. find that miRNAs can also control behavior in the fruit fly Drosophila. My comment: Ridiculous claims from 1) We are all mutants and from 2) Mutation-Driven Evolution can now be placed into the context of what is known to…
