The futility of The Battlefield FB group

Apparently, Paul Hartley blocked me from further discussion of his OP about dinosaurs and gladiators before I could ask if he thought “The Battlefield” is a “false flag” group. Does anyone else think that?   If so, do you think it can survive publication of experimental evidence that links responsive supramolecular systems to stepwise changes in the assembly of metal complexes via induction of a light-driven rotary motor scaffold akin to the bacterial flagellum of P. fluorescens? See: Dynamic control…

Epigenetic (re)programming of behavior (3)

Bipolar drug turns foraging ants into scouts Excerpt: “DNA methylation has become nearly synonymous with epigenetics,” says Brendan Hunt, an insect geneticist at the University of Georgia in Griffin. “This research brings needed attention to the importance of other epigenetics marks, like histone modifications.” “We finally have a mechanism to understand ‘nurture’ in molecular terms,” says Gene Robinson, a geneticist at the University of Illinois, Urbana-Champaign, who studies caste determination in honey bees. The ant study, he adds, highlights “how…

From 3-D to epigenetically-effected 4-D genome make-up

Discoveries in 3-D Genome Make-Up and Genetic Changes: Clarification of differences amidst chromosome pairs and how gene expression is effected by chromosome folding Excerpt: “…offers a useful guide for future studies of the epigenome’s function in our evolution and diseases that beset us.” My comment: The guide is also useful because it shows how the anti-entropic effects of light-induced amino acid substitutions links the epigenetic landscape to the physical landscape of DNA in species from microbes to man. For example,…

Behavior (3): All responses are RNA-mediated in bees

See: Honey bees as a model for understanding mechanisms of life history transitions. Excerpt: “In this review we discuss the physiological and genetic mechanisms of this behavioral transition, which include large scale changes in hormonal activity, metabolism, flight ability, circadian rhythms, sensory perception and processing, neural architecture, learning ability, memory and gene expression.” My comment: An earlier review by Eleckonich and Robinson (2000) “Organizational and activational effects of hormones on insect behavior” cited our 1996 review of epigenetically-effected organization and activation…
