Among the insect olfactory receptors the odorant receptors (ORs) evolved in parallel to the onset of insect flight. A special property of this receptor type is the capability to adjust sensitivity of odor detection according to previous odor contacts. This article presents a current view on regulatory processes affecting the performance of ORs and proposes a model of mechanisms contributing to OR sensitization.
Future attempts to place psychophysical laws of biology back into the context of neo-Darwinian pseudoscientific nonsense will continue to pit ridiculous theories about experience-dependent tuning of odor receptors against everything known to serious scientists about RNA-mediated biophysically constrained viral latency and supercoiled DNA.

Epithelial-to-Mesenchymal Transition (EMT) and its reverse – Mesenchymal to Epithelial Transition (MET) – are hallmarks of cellular plasticity during embryonic development and cancer metastasis.
Cellular plasticity was linked from the energy-dependent pheromone-controlled physiology of reproduction in bacteria to our visual perception of energy and mass in the context of the space-time continuum.
See: Olfaction Warps Visual Time Perception (2017)
The behavioral gain produced by a congruent relative to an incongruent odor is accompanied by elevated neural oscillatory power around the object’s flicker frequency in the right temporal region ~150-300 ms after object onset, and is not mediated by visual awareness. In parallel, odors bias the subjective duration of visual objects without affecting one’s temporal sensitivity.

The anti-entropic force of virucidal ultraviolet light links guanine–cytosine (G⋅C) Watson–Crick base pairing from hydrogen-atom transfer in DNA base pairs in solution to supercoiled DNA, which protects the organized genomes of all living genera from virus-driven entropy. For example, protection of DNA from permanent UV damage occurs in the context of photosynthesis and nutrient-dependent RNA-directed DNA methylation, which links RNA-mediated amino acid substitutions to DNA repair. In the context of thermodynamic cycles of protein biosynthesis and degradation, DNA repair enables the de novo creation of G protein coupled receptors (GPCRs). Olfactory receptor genes are GPCRs. The de novo creation of olfactory receptor genes links chemotaxis and phototaxis from foraging behavior to social behavior in species from microbes to humans. Foraging behavior links ecological variation to ecological adaptation in the context of this atoms to ecosystems model of biophysically constrained energy-dependent RNA-mediated protein folding chemistry. Protein folding chemistry links nutrient-dependent microRNAs from microRNA flanking sequences to energy transfer and cell type differentiation in the context of adhesion proteins, and supercoiled DNA that protects all organized genomes from virus-driven entropy.

Feedback loops link quantized energy as information to biophysically constrained RNA-mediated protein folding chemistry. Light induced energy-dependent changes link angstroms to ecosystems from classical physics to chemistry/chirality and to molecular epigenetics/autophagy. The National Microbiome Initiative links microbial quorum sensing to the physiology of reproduction via endogenous RNA interference and chromosomal rearrangements. The rearrangements link energy-dependent fixed amino acid substitutions to the Precision Medicine Initiative via genome wide inferences of natural selection.
This detailed representation of energy-dependent natural selection for codon optimality links biologically- based cause and effect from G protein-coupled receptors to RNA-mediated amino acid substitutions and the functional structure of supercoiled DNA. Energy-dependent polycombic ecological adaptations are manifested in supercoiled DNA. Chromosomal inheritance links the adaptations from morphological phenotypes to healthy longevity via behavioral phenotypes. For contrast, virus-driven energy theft is the link from messenger RNA degradation to negative supercoiling, constraint breaking mutations, and hecatombic evolution. The viral hecatomb links transgenerational epigenetic inheritance from archaea to Zika virus-damaged DNA, which typically is repaired by endogenous RNA interference and fixation of RNA-mediated amino acid substitutions in organized genomes.

Webinar: Deciphering how bacteria utilize outer membrane vesicles (OMVs) to communicate and infect
Outer Membrane Vesicles (OMVs) are membrane vesicles secreted by bacteria that contain DNA, RNA, proteins and endotoxins. Bacteria respond to many environmental factors by secreting specifically-enriched OMVs, which makes these bacteria more fit for their environment. For example, OMVs may be enriched with invasion proteins at the host-pathogen interface. OMVs have recently gained attention as a novel mechanism for transmission of molecular information within bacteria as well as between bacteria and mammalian cells. Owing to their similarities to well-studied extracellular vesicles (EVs), OMVs are being utilized by researchers to study host-bacterial interactions in pathogenesis, cancer therapy, host immune response modulation, as well as bacterial OMV engineering for use as vaccines. This webinar will give an overview of recent studies on the role of OMVs in host-pathogen interactions and discuss their bioengineering potential as vehicles for cargo delivery. We will also introduce our new & revolutionary ExoBacteria™ OMV Isolation Kit, which will enable you to achieve faster, simpler & better OMV isolation.
