Drosophila melanogaster

From photons to the proton motive force (1)

Conclusion: If you would like to learn how to link quantized energy-dependent changes in atoms to ecosystems in all living genera via the physiology of reproduction, join others age 10+ who will be playing this game in September 2018. Fly’s Blood-Brain Barrier Has Circadian Rhythms “the anatomic characteristics of insect and vertebrate BBB structures are quite distinct.” The molecular mechanisms are conserved. My comment to The Scientist: Feedback of the Drosophila period gene product on circadian cycling of its messenger…

Host-derived creation of all pathology (2 of 2)

Summary: All serious scientists know that all epigenetic diversity is food energy-dependent and biophysically constrained by the pheromone-controlled physiology of reproduction. See for comparison: Jay R. Feierman: “Variation is not nutrient availability and the something that is doing the selecting is not the individual organism. A feature of an educated person is to realize what they do not know. Sadly, you don’t know that you have an incorrect understanding [of] Darwinian biological evolution.” A Bacterial Messenger Molecule Extends Healthspan …indole,…

Half truths support theories without facts

How to lie by telling the truth Excerpt: People… trot out half-truths, in full expectation and knowledge that they will create a false impression. And then, when others act on the false impression, the “truth-telling liars” can sit back and pretend that they aren’t liars. They get the benefit of lying, without any damage to their precious self-image. My comment: It is more difficult for others to determine who benefits from half truths when more than one individual or research…

More than a bag of chemicals?

From Fertilization to Adult Sexual Behavior (1996) Excerpt: “Small intranuclear proteins also participate in generating alternative splicing techniques of pre-mRNA and, by this mechanism, contribute to sexual differentiation in at least two species, Drosophila melanogaster and Caenorhabditis elegans…” My comment: How far can this model of RNA-mediated cell type differentiation go? What links the model to ADHD? Could it be a single amino acid substitution (see below)? If so, can the response to ADHD pharmacotherapy be predicted by what is…
