Differential Expression of Putative Pheromone-detecting Cells and Receptors in the Olfactory Epithelium of an African Cichlid Fish
The link from sunlight and chirality to nutrient energy-dependent reproduction is not addressed in the presentationss from SICB 2017
There is nothing in a search for chirality
At the 2016 meeting, Epigenetic regulation of Toll-like Receptor 4 expression as a facilitator of invasiveness in Kenyan house sparrows (Passer domesticus) seemed to suggest that epigenetic regulation automagically occurred.
There is one abstract fron 2017 that links sunlight to chirality without reporting on chirality, but at least they report on autophagy.
Disease Resistant Corals Activate Autophagy over Apoptosis after an Immune Challenge 

…disease resistant corals upregulated pathways involved in autophagy, indicating attempts at adapting to changing conditions. These data show how cell survival pathways contribute to the immune response and subsequent patterns of disease resistance on coral reefs. Understanding these mechanisms will help inform trajectories of reefs under continuous climate and disease pressure.

There is one 2017 abstract that links chirality and autophagy to energy-dependent RNA-mediated amino acid substitutions.
ATP Production Increases with Addition of Varying Concentrations of Vespa Amino Acid Mixture (VAAM)

…our previous work suggests VAAM affects the electron transport chain and ATP synthase activity. While increased exercise capacity shortly after VAAM exposure has been observed in multiple species, the relationship between VAAM and ATP production has been assumed without supporting data, until now.

They haven’t decided whether or not RNA-mediated DNA repair is a good thing.

We identified 16,194 transcripts in the VL and found ~25.5% appear to be cephalopod-specific. Next we used targeted and unbiased computational predictions and manual annotation to identify putative signaling molecules form the VL transcriptomes. We have cloned and localized 11 neuropeptides (NP) to components of the VL circuit. NPX3 is abundantly expressed in the cell bodies of the SFL, where the VL circuit originates and NPX1 & 2 localize to the AM cell bodies of each VL gyrus. Among the 7 NPs that localize to the VL LE neurons, 2 unique cephalopod NPs, NPX4 & 5, are abundant in Octopus, but absent in the ancestrally branching Nautilus (which lacks a VL). This expansion of signaling molecules in the VL circuit may be a key feature of unique memory systems of cephalopods, implying extensive parallel evolution of cephalopod brains and memory circuits.

The expansion of the signaling molecules is nutrient energy-dependent and the increasing organismal complexity is pheromone-controlled via the physiology of reproduction in species from microbes to humans.
Conservation, convergence, and novelty in Octopus bimaculoides embryogenesis

To shed light on the gene networks important in this highly derived developmental program, we sequenced and analyzed transcriptomes from five stages spanning embryogenesis in the California two-spot octopus, Octopus bimaculoides. Genome analysis has shown that the core developmental gene repertoire of the octopus is broadly similar to that found in typical invertebrate bilaterians (Albertin et al. 2015). We detect transcripts for these developmental transcription factors and signaling ligands primarily during the middle stages that coincide with the emergence of the body plan, but not before. Bioinformatics-based differential expression analysis identified suites of genes that show dynamic changes, including stage-specific expression profiles. Notably, many of the differentially expressed genes in the early transcriptomes are not found in the genomes of other sequenced animals. These results indicate that the fish-like early stages of cephalopod development deploy cephalopod-specific genes, and suggest a major role for taxonomically restricted genes in the evolution of cephalopod developmental mechanisms.

They fail to link the sun’s anti-entropic virucidal energy to the light they try to shed on gene networks that automagically “…coincide with the emergence of the body plan, but not before.” The coincidental emergence fails to link Dobzhansky’s (1973) “light of evolution” to deferentially expressed genes that are not found in the early transcriptomes or organized genomes of other sequenced animals.
Behavioral Dynamics of Niche Partitioning between Two Octopus Species in a Shallow Coastal Environment

O. vulgaris uses parachute attack and spends more time foraging on rock and rubble, mostly nocturnally. This study identifies ecological and behavioral components that facilitate coexistence of sympatric species, provides insight into cephalopod ecology and baseline conservation requirements for unique sand-dwelling organisms.

They link nutrient energy-dependent changes in niche construction from ecological variation to ecological adaptation and the coexistence of sympatric species via foraging behaviors, foraging times and diet, but fail to link the foraging and diet to the pheromone-controlled physiology of reproduction and transgenerational epigenetic inheritance of morphological and behavioral phenotypes in all living genera via conserved molecular mechanisms of biologically-based cause and effect..
Feeding on the Unseen: Ingestion and Assimilation of Bacteriophages by Brachionus plicatilis (Rotifera)

… bacteriophages (< 0.05 μm) are abundant in seawater (to 108/mL) and represent a potential food source for rotifers and other planktonic invertebrates.

They linked the ingestion of viruses from metabolic networks to genetic networks via dichlorotriazinylamino fluorescein (DTAF)-labeled bacteriophages and found that the fluorescence of rotifers was greater in the DTAF-bacteriophage treatments, which led to the hypothesis that viuses in seawater may be a food source for planktonic invertebrates and their larvae.
See for comparison: Viral and cellular messenger RNA targets of viral microRNAs appear to link the nutrient energy-dependent physiology of pheromone-controlled reproduction to protection from virus-driven energy theft and genomic entropy via virally encoded microRNAs. The virus-driven energy theft benefits the viruses. Nutrient energy-dependent metabolic and genetic networks link hydrogen-atom transfer in DNA base pairs in solution form energy-dependent microRNA flanking sequences to viral latency (prevention of viral replication cycles) in the context of energy-dependent autophagy.
Abstract excerpt:

Emerging data suggest that viral miRNAs may be particularly important for regulating the transition from latent to lytic replication and for attenuating potentially inhibitory host antiviral immune responses.

It is time to link the emerging data to energy-dependent healthy longevity and virus-driven energy theft to all pathology, instead of playing word games. See for example: Epigenetics and Genetics of Viral Latency

… viral latency is responsible for life-long pathogenesis and mortality risk…

We show here for the first time the crucial role of viruses in controlling archaeal dynamics and therefore the functioning of deep-sea ecosystems, and suggest that virus-archaea interactions play a central role in global biogeochemical cycles.

They insult the intelligence of any serious scientist who has ever linked energy-dependent changes from angstroms to ecosystems and all healthy longevity and all serious scientists who have linked virus-driven energy theft to all pathology via the transgenerational epigenetic inhertance that links the virus-mediated archaeal hecatomb to Zika virus-damaged DNA in human infants.

Pheromone-mediated Communication in a Bird Ectoparasite

Pheromone-mediated communication governs many aspects of insect behavior, population dynamics, and community ecology.

We are currently working to determine the structures of volatile compounds produced by lice and to identify their use in pheromonal communication.

Evolutionary Mechanisms that Inhibit Interspecies Mating in Drosophila

Given that the sensory pathway for inhibiting inter-species mating is conserved, we are using modern genetic tools to understand how the neural circuits underlying mate choice have evolved in disparate fly species. We generated novel transgenic lines in D. melanogaster and other fly species to determine whether Gr32a functions in an analogous manner across species. These studies involve examining the control of Gr32a expression and its function in different species. Taken together, my studies will lead to a better understanding of how behavioral reproductive isolation has evolved.

Reproductive isolation did not evolve. Thomas Hunt Morgan won the 1933 Nobel Prize in Physiology or Medicine for his works on chromosomal inheritance and Schrodinger/Dirac won the Prize
Flight Stability and Olfactory Navigation is Supported by Multisensory Antennal Inputs in the Moth Manduca sexta 

To characterize the effects of different environments on plume tracking, we challenged males with only one odor-detecting antenna to track a plume in an either turbulent or laminar air flow.

Be ready to compare the reports from science journalists to what was known about moth pheromones in 1959 and energy-dependent RNA synthesis in 1964.
Pheromones: a new term for a class of biologically active substances

Obama Advisers Urge Action Against CRISPR Bioterror Threat

For the past two decades, the government has focused its biodefense efforts on a list of known pathogens—such as anthrax, smallpox, and Ebola—declared by the Department of Health and Human Services and Department of Agriculture to have the “potential to pose a severe threat to public health and safety.” Government-funded research on these pathogens receives special scrutiny, and the National Institutes of Health limits researchers from conducting experiments that could make certain germs, like influenza, more dangerous.

Opsin-based light sensing is clearly critical for behavioral light responses… CRY is a major modulator of a wide range of fly behavioral responses to UV light.

This may be your last chance.

1) Admit that the de novo creation of G protein-coupled receptors links the anti-entropic virucidal effects of UV light to the innate immune system and supercoiled DNA.
2) Admit that supercoiled DNA links chemotaxis and phototaxis to the pheromone-controlled weekend resurrection of the bacterial flagellum.
3) Admit that the weekend resurrection of the bacterial flagellum attests to what is known to all serious scientists about biophysically constrained RNA-mediated protein folding chemistry.
Alternatively, wait for serious scientists to demand that you and all other theorists be ousted from your positions in academia if you do not stop touting pseudoscientific nonsense about beneficial mutations and evolution. Energy is information and virus-driven energy theft links mutations to all pathology. If you do not agree, try to invent another theory on your way out the door of your ivory tower.

This article is part of the Research Topic Brain nutrient sensing in the control of energy balance: new insights and perspectives


It is well established that nutrients act as signaling molecules in synergy with nervous and hormonal signals to inform the brain about the nutritional status of the body. The integration of these signals within the hypothalamus and other brain regions triggers behavioral and physiological responses through efferent autonomic nerves, hypothalamic-pituitary-Adrenal and thyroid axis in order to maintain energy homeostasis. In particular, the roles of glucose, fatty acid and amino acid sensing in the control of food intake and peripheral glucose metabolism have been extensively studied. Cellular and molecular mechanisms by which circulating nutrients act on the brain have become a highly competitive field with outcomes leading to several strategies to prevent or treat obesity and its co-morbidities.

In the past decade the field of brain nutrient-sensing has seen a profound evolution with, for instance, the predominant role for an interplay between homeostatic and non-homeostatic control of food intake and energy balance. The latter takes place in the mesolimbic system and recapitulates the rewarding and motivational aspects of feeding. In addition, other brain regions known for their role in memory (hippocampus), olfaction (olfactory bulbs) and circadian clock (suprachiasmatic nucleus) have emerged as nutrient sensitive areas contributing to feeding behavior and energy homeostasis. Finally, growing evidence suggests that the interplay between glial cells and neurons is fundamental in nutrient sensing.

In parallel to these new developments, several novel methodologies have emerged to dissect the neurocircuitries regulating feeding behavior and energy homeostasis, including optogenetics, DREAD, cell specific deletion… Together, these approaches will help to better understand the interplay between brain regions and circuits involved in nutrient sensing.
This Frontiers Research Topic aims to focus on new insights and perspectives in brain nutrient sensing (both in physiological and pathophysiological conditions) with a special attention to the multi-scale deciphering of cell inner mechanisms. In this regard contributors are encouraged to submit reviews, mini-reviews, commentaries, perspective articles, original research articles and method articles.

My invited review of nutritional epigenetics and microRNA-mediated cell type differentiation was returned without review by the journal editors at “Nutrients.”

Stress-induced structural plasticity of medial amygdala stellate neurons and rapid prevention by a candidate antidepressant

Reported as: New Signs of Stress Damage to the Brain: Mouse Study


Nasca and her colleagues’ experiments included mice at high risk of developing anxiety- and depression-like behaviors in response to stress. Treatment with acetyl carnitine also appeared to protect these mice, suggesting that a similar preventative approach might work for depression-prone people.

Both humans and rodents naturally produce acetyl carnitine under normal conditions and several depression-prone animal models are deficient in acetyl carnitine. In a separate study, Nasca and colleagues are examining whether people with depression have abnormally low levels of the molecule.

The links from everything know to serious scientists about biophysically constrained RNA-mediated cell type differentiation can be compared to outcomes linked to healthy longevity or from virus-driven energy theft to mutations and all pathology via carnitine metabolism.

The journal article cites: Magarinos AM, McEwen BS. Stress-induced atrophy of apical dendrites of hippocampal CA3c neurons: involvement of glucocorticoid secretion and excitatory amino acid receptors. Neuroscience 1995; 69:89–98.

It does not link virus-driven energy theft to experience-dependent changes in RNA-methylation that have already been linked from RNA-directed DNA methylation to learning and memory during life history transitions by this group, and in the context of this report: Oppositional COMT Val158Met effects on resting state functional connectivity in adolescents and adults.

The likelihood that no one else has linked virus-driven energy theft to experience-dependent changes in RNA-methylation, which that have already been linked from RNA-directed DNA methylation to learning and memory during life history transitions, suggests that others have not followed the best advice I ever received. In the early 1990’s, I was told that my model could not be validated unless I could show that gene activation occurred in hormone-secreting neurons of the hypothalamus that all serious scientist know link energy-dependent RNA-mediated cell type differentiation to all biodiversity and also link virus-driven energy theft from mutations to all pathology via the physiology of reproduction in all living genera.

I did that, and co-authored a book, and have since published a series of articles with co-authors or as monographs. Most people remain uninterested and many are antagonistic because they don’t like the experimental evidence of biologically-based cause and effect that I included in my model. They prefer ridiculous theories.
