The eternal significance of microRNAs (8)

Use of definitions in attempts to explain any aspect of species-specific biophysically constrained cell type differentiation and aging has been replaced by the use of model systems of biological processes.  Biological processes can be compared to so-called “evolutionary processes” to show that only biological processes need to be considered in the context of Darwin’s “conditions The eternal significance of microRNAs (8)

Physicists: Desperate Acts (revisited)

Physicists: Desperate Acts Light-induced endogenous RNA interference in bioluminescent microbes links Schrodinger’s claims in “What is LIfe?” (1944) from a light-to-chemical pathway of information exchange in all living genera via amino acid substitutions in supercoiled DNA. All subsequent works on the evolutionary synthesis failed to link  the anti-entropic virucidal energy of sunlight to Darwin’s “conditions Physicists: Desperate Acts (revisited)

Expunging the distinguished public

Royal Society Expunges Public From Evo Record Many of the attendee-participants were, in fact, more distinguished than many of the actual speakers. So the audience came to be heard as well as to listen. But the official recording (now posted) has been wiped clean of public comment — the most robust part of the meeting Expunging the distinguished public

Energy-dependent cellular communication

Communication shapes sensory response in multicellular networks Significance Cells routinely sense and respond to their environment, and they also communicate with each other. Exactly how communication impacts sensing remains poorly understood. We study a population of fibroblast cells that responds to a chemical stimulus (ATP) and communicates by molecule exchange. Combining experiments and mathematical modeling, Energy-dependent cellular communication

Anthetical conclusions

Something is antithetical when it is in complete and utter opposition to the character of something. Analysis of protein-coding genetic variation in 60,706 humans reported as: Largest collection of human exome sequence data yields unprecedented tool for diagnosing rare disease …variation that was expected, but not found, in the data offered new insight. Some genes Anthetical conclusions

MicroRNAs and sexual orientation

A neural circuit encoding sexual preference in humans Excerpt: We anticipate the identification of a core neural circuit for sexual preferences to be a starting point for further sophisticated investigations into the neural principles of sexual behavior and particularly of its aberrations. My comment: They link sexual orientation in yeasts to humans but fail to MicroRNAs and sexual orientation
