epigenetic modifications

The overwhelming ignorance of sex researchers

Summary: J. Michael Bailey, and others like him, pretend to not know how non-coding variants are epigenetically linked from differences in hydrogen bonds to all energy-dependent biophysically constrained morphological and behavioral phenotypes. Genome-Wide Association Study of Male Sexual Orientation [Energy-dependent changes in biophysically constrained viral latency] We identified several [energy-dependent changes in] SNPs with p < 10−5, including regions of multiple supporting SNPs on chromosomes 13 (minimum p = 7.5 × 10−7) and 14 (p = 4.7 × 10−7). The genes nearest to these peaks have functions plausibly relevant to…

Epigenetic facts vs variable recombination theories

6/14/13 Nutrient-dependent/pheromone-controlled adaptive evolution: a model ….the model represented here is consistent with what is known about the epigenetic effects of ecologically important nutrients and pheromones on the adaptively evolved behavior of species from microbes to man. Minimally, this model can be compared to any other factual representations of epigenesis and epistasis for determination of the best scientific ‘fit’. 7/25/13 Jay R. Feierman: Variation is not nutrient availability and the something that is doing the selecting is not the individual…

What is life without sunshine?

Summary: It seems likely that Schrodinger’s anti-entropic virucidal effect of sunlight will be linked to the RNA-mediated de novo creation of all organized genomes and the maintenance of the “spotless epigenome” in this presentation later today. If so, even theorists and other pseudoscientists who planned to “March for Science” will finally be seen in the context of Dobzhansky’s claims about the “…light of evolution.” Erasing Epigenetic Marks: Eternal Sunshine of the Spotless Epigenome Topics to be covered: The variety of…

Bill Gates refutes theistic evolution (sequel)

See: Bill Gates refutes theistic evolution See also: Gate-controlled conductance switching in DNA Conclusion: Our work demonstrates one can introduce an active control to DNA conductance by modifying a base with a redox group, and switch the DNA conductance reversibly between two levels by oxidizing or reducing the redox group with an EC gate. This strategy could be implemented in more sophisticated DNA nanostructures for active device building blocks. As the DNA conductance is an indicator of the molecule in…

Bill Gates refutes theistic evolution

See: Bill Gates refutes theistic evolution (prequel) See for comparison: Our 2017 Annual Letter Warren Buffett’s Best Investment By Bill and Melinda Gates | February 14, 2017 Malnourished children can be getting enough calories, but not the right nutrients. That makes them more susceptible to conditions like pneumonia or diarrhea—and more likely to die from them. If malnourished children are not getting the right nutrients, they focused too much on vaccines and not enough on what is known about nutritional…

Antithetical conclusions (4)

Evidence for sex-specific genetic architectures across a spectrum of human complex traits …will need to disentangle whether sex genetic heterogeneity may arise as a consequence of interactions with genetic loci located on the sex chromosomes, differences in gene control due to differences in the sex-specific cellular environment, or more general differences in environmental exposures between the sexes. Nutrient energy-dependent pheromone-controlled sex differences in the cell types of species from yeasts to humans link changes in the microRNA/messenger RNA balance and…

Energy-dependent RNA methylation (6)

After I published Nutrient-dependent/pheromone-controlled adaptive evolution: a model, Lynnette Ferguson and Justin O’Sullivan invited me to submit this review of nutritional epigenetics for inclusion in a special issue of the journal “Nutrients.” Nutrient-dependent pheromone-controlled ecological adaptations: from atoms to ecosystems (April 10, 2014) Abstract: This atoms to ecosystems model of ecological adaptations links nutrient-dependent epigenetic effects on base pairs and amino acid substitutions to pheromone-controlled changes in the microRNA / messenger RNA balance and chromosomal rearrangements. The nutrient-dependent pheromone-controlled changes…

Virus-driven disorder prevention and health promotion

The dynamic epigenome and its implications for behavioral interventions: a role for epigenetics to inform disorder prevention and health promotion Excerpt: Evidence has also been growing about the role of epigenetic modification in response to the social environment. My comment: Unexpectedly, Szyf et al., (2016) fail to mention all the evidence of epigenetically-effected RNA-mediated cause and effect that has accumulated since we published our 1996 Hormones and Behavior review. That may explain why they also failed to link energy-dependent hydrogen-atom…

Neuroscience Virtual Event vs AAAS Symposium

Neuroscience Virtual Event Abstract Submission Poster title: From hydrogen-atom transfer in DNA base pairs to ecosystems (March 16-17, 2016) Abstract: This atoms to ecosystems model of ecological adaptations links nutrient-dependent epigenetic effects on DNA base pairs in solution and RNA-mediated amino acid substitutions to chromosomal rearrangements via pheromone-controlled changes in the microRNA / messenger RNA balance. The nutrient-dependent pheromone-controlled changes are required for the thermodynamic regulation of intracellular signaling, which enables biophysically constrained nutrient-dependent & pH-dependent protein folding; experience-dependent receptor-mediated behaviors,…

Did Dobzhansky see the UV light of creation?

Analemma. The sun’s position in the sky, photographed from the same location at the same time of day throughout a year, forms an analemma. This shows the sun’s apparent swinging from its northernmost position, at the analemma’s uppermost point, at summer solstice, to its southernmost position/lowest point, at winter solstice. My comment: Does this remind anyone else of a one-sided nonorientable surface obtained by cutting a closed band into a single strip with linked ends that can be used to…
