Assembling yourself: Molecular self / other recognition

Chiral recognition and selection during the self-assembly process of protein-mimic macroanions Abstract excerpt: “We believe that delicate long-range electrostatic interactions could be responsible for such high-level chiral recognition and selection.” Article excerpt: “This self-assembly allows relatively simple building blocks to organize themselves into larger supramolecular structures, a phenomenon that has parallels with the formation of viral capsids (both in morphology and kinetics)37.” Reported as: Discovery demystifies origin of life chirality phenomenon Excerpt: “The origin of life is still a mystery…

Probable changes in connectivity

Table of Contents: Nature Reviews Neuroscience October 2014 Vol 15 No 10 Excerpt from: Research Highlights: Learning and memory: Uncoupling memory traces “The emotional valence of a memory can be changed, and this probably involves a change in the connectivity between hippocampal and amygdalar memory traces.” My comment: 1) The connectivity change is epigenetically-effected by olfactory/pheromonal input. 2) Epigenetically-effected RNA-mediated events link the epigenetic landscape to the physical landscape of DNA in species from microbes to man. 3) Conserved molecular…

Social experiences epigenetically effect gene networks

Networks of Genes Respond to Social Experiences October 13, 2013, from Searching for the Mind with Jon Lieff, M.D. Excerpt 1: “The gene networks of social experience are consistent through many animals.” My comment: Not just many animals; the gene networks of social experiences must be consistent in all animals that adaptively evolved. You cannot get from microbes to man with any consistent model of cause and effect until you realize that the molecular mechanisms that enable cause and effect…
