An epigenetic trap (the prequel)

terrarium eco system

See also: An epigenetic trap (the sequel) Excerpt: “Support for the link from one epigenetic trap to cell type differentiation was included in the molecular epigenetics section of our 1996 review, which detailed how RNA-mediated chromatin remodeling occurs.” My comment:…

Converting sunlight to fuel: O2 and CO2 Reactions

Physics

Efficient solar-to-fuels production from a hybrid microbial–water-splitting catalyst system Abstract excerpt:  “…we report the development of a scalable, integrated bioelectrochemical system in which the bacterium Ralstonia eutropha is used to efficiently convert CO2, along with H2 and O2 produced from…

Are viruses microRNAs? (2)

terrarium eco system

The role of microRNAs in cell type differentiation can be compared in the context of the role of viruses and mutations that cause cancer. Facts provide a basis for explaining the biological basis of epigenetically-effected cell type differentiation in species…

Prehistoric genomes reveal the genetic foundation and cost of horse domestication Reported as: Reshaping the horse through millennia Excerpt: “Domestication is generally associated with repeated demographic crashes. Yet, mutations that negatively impact genes are not eliminated by selection and can even…

The future of physics predicts no future for evolutionary theory

Physics

The ever-smaller future of physics ‘Theory of everything’ captures Weinberg’s imagination in Lee Historical Lecture Excerpt: “…there are hints that the answers to fundamental questions will reveal themselves at around a million billionths — between 10­-17 and 10-19 — of…

Horizontal Transfer of Entire Genomes via Mitochondrial Fusion in the Angiosperm Amborella (December, 2013) Excerpt) “The ancestral angiosperm-wide genome duplication apparent in the Amborella genome not only serves as a genetic marker for the origin of extant angiosperms, but it…

We need pattern recognition, not a prologue

rp_poster-from-jesse.jpg

Prolegomenon “a preliminary discussion…; a prologue.” “… we need a mapping from genotype to phenotype, from phenotype to what is selected, and from what is selected to the new genotype (Lewontin, 1961). — cited in Prolegomenon to patterns in evolution…

Reappraisal of known malaria resistance loci in a large multicenter study Abstract excerpt: “The finding that G6PD deficiency has opposing effects on different fatal complications of P. falciparum infection indicates that the evolutionary origins of this common human genetic disorder…

Physics denied; pseudoscientific nonsense accepted

Physics

  The events depicted are now portrayed in the context of Genome Dynamics Events, which are biophysically-constrained RNA-mediated events. RNA-mediated events lead to amino acid substitutions that differentiate the cell types of species. For example: “…the so-called alpha chains of…
