Metabolism, fixation, health or neurodegerative disorder

“Shown is the location of the conserved regions encoding for the N-terminal chromo domain and the C-terminal MYST functional domain. An arrow denotes the position site of amino acid substitution E431Q.” Microarray Analysis Uncovers a Role for Tip60 in Nervous System Function and General Metabolism My comment: The article links a nutrient-dependent amino acid substitution via changes in metabolism to cell type differentiation, multicellularity, and brain development in Drosophila. It suggests the substitution is fixed by the model organism’s pheromone-controlled…

Physics, Chemistry, and Molecular biology (PCMb)

Physics, Chemistry, and Molecular biology (PCMb) link ecological variation to ecological adaptations via a model of gene-cell-tissue-organ-organ system complexity that I first presented in 1992. After adding gene activation by pheromones, I co-authored a book that linked the pheromone-controlled physiology of reproduction across species from microbes to man: The Scent of Eros: Mysteries of Odor in Human Sexuality (1995/2002) Since then, others have written books that claimed that pheromones evolved: Pheromones and Animal Behaviour (2003/2014) and one claimed that mammals…

A molecular visualizer of worthwhile molecular biology

Ruben Gonzalez Jr.: Molecular Visualizer Associate Professor and Director of Graduate Studies, Department of Chemistry, Columbia University. Age 42 By Jef Akst | September 1, 2014 Excerpt: “Much of his group’s current work involves extending discoveries about translation in E. coli to the process in eukaryotes, with an eye toward human health and disease.” My comment: That sums up the frustration that other serious scientists must share when they hear pseudoscientific nonsense touted about mutations, natural selection, and the evolution…

Insect homology and diversity attributed to mutations

Ancient homology underlies adaptive mimetic diversity across butterflies Excerpt: “Surprisingly, our results suggest that modulation of this conserved developmental gene has occurred in tandem between these two deeply divergent butterfly lineages, implying an unexpected and remarkable level of predictability in the evolutionary process.” Reported as: A single evolutionary road may lead to Rome Excerpt: “Copying errors and genomic viruses directly lead to the wing patterns of these beautiful butterflies,” Gallant said. “It’s these accidents that allow the evolutionary process to…

The quantum biology of consciousness

Everything known about quantum biology “…suggests conscious experience is intrinsically connected to the fine-scale structure of space–time geometry, and that consciousness could be deeply related to the operation of the laws of the universe.” See for review: Consciousness in the universe: A review of the ‘Orch OR’ theory. These laws of the universe might lead others to think in terms of “laws of biology” (biological laws). Indeed, many informed scientists could expect that ecological, social, and neurogenic niche construction would result…

Don't tell the Creationists

Misquoting Science in the Texas Textbook Battles James A. Shapiro Author, ‘Evolution: A View from the 21st Century’; Professor of Microbiology, University of Chicago Posted: 12/05/2013 3:57 pm Excerpt: “Uncovering the molecular mechanisms by which living organisms modify their genomes is a major accomplishment of late 20th Century molecular biology.” Collectively, I call these processes Natural Genetic Engineering. Symbiogenetic cell fusions, horizontal DNA transfer, mutagenic DNA repair, reverse transcription of RNA into DNA, mobile genetic elements, interspecific hybridization and whole…
