Your indifference is killing you and others

Summary: Coherence-inducing mechanisms is double-speak for mechanisms that are nutrient-dependent and pheromone-controlled. Feedback loops link odor and pheromone signaling with reproduction has been presented in double-speak as Looplessness in networks is linked to trophic coherence We are currently studying the entropy of the coherence ensemble we defined for this work. “In general, higher trophic coherence would be associated with lower entropy states, which means that if networks are more coherent than the random expectation there must indeed be some kind…

The Origin of Information (3)

Summary: I presented two poster sessions during the Labroots virtual conference “Neuroscience,” March 16-17, 2016 One linked sunlight to energy as the origin of information. The other linked energy as information to biophysically constrained viral latency via the pheromone-controlled physiology of reproduction in all living genera. Additional experimental evidence of top-down causation has since confirmed that the creation of sunlight can be linked from energy as information to all biodiversity via its anti-entropic virucidal effects. The direct quantitative measurement of…

Energy-dependent pheromone-controlled entropy (2)

See also: Energy-dependent pheromone-controlled entropy (1) Let’s make peer review scientific …peer review is often biased and inefficient. It is occasionally corrupt, sometimes a charade, an open temptation to plagiarists. Even with the best of intentions, how and whether peer review identifies high-quality science is unknown. It is, in short, unscientific. The androgynous baby-faced boy or girl pictured among those wearing pink “crotch” hats appears to representing others at the March for Women. The sign may also be representing the…

Base pairs, olfaction and RNA thermometers

RNA thermometer controls temperature-dependent virulence factor expression in Vibrio cholerae (2014) Excerpt: The stem-loop can be stabilized by strengthening the base pairing between the fourU element and SD sequence through the substitution of G-C base pairs, and this results in an elevated melting temperature (10). Conclusion: RNA thermometers represent a simple yet elegant mechanism for controlling temperature-dependent gene expression and may be more widespread among pathogenic bacteria that interact with mammalian hosts than is currently known.

Chromatin: The structure of DNA (2)

A Genetically Encoded Probe for Live-Cell Imaging of H4K20 Monomethylation Excerpt (with my emphasis): Highlights •    A histone H4K20me1-specific live-cell probe, H4K20me1-mintbody, was developed. •    Dynamics and replication timing of Xi were visualized. •    Critical amino acids for the stability and/or folding of the mintbody were revealed. Reported as: Catching histones by the tail: A new probe to track histone modifications in living cells Excerpt: H4K20me1 is most likely associated with the tight packing of a redundant (inactivated) female X…

The Aquatic Ape / Waterside Ape divergence

See also: The Aquatic Ape: New evidence? (9/8/16) Walt Patrick  Now that I’m semi-retired…. My major focus is the development of village-scale energy sovereignty. I believe that sustainable community stands on an interlocking foundation of effective and sustainable energy systems, and I’m working to develop ways that a community can meet its energy needs without having to rely on multi-national energy corporations. My comment: Thanks to Walt for introducing me to Elaine Morgan’s work. He loaned me his copy of…

Linking RNA structure to function

A G-Rich Motif in the lncRNA Braveheart Interacts with a Zinc-Finger Transcription Factor to Specify the Cardiovascular Lineage was reported on September 8, 2016 as: Linking RNA structure and function Excerpt 1) Learning more about how lncRNAs control cell differentiation could offer a new approach to developing drugs for patients whose hearts have been damaged by cardiovascular disease, aging, or cancer. The insult to the intelligence of all serious scientists who have linked energy-dependent changes from angstroms to ecosystems in…

Biophotonics, glycobiology, quantized biodiversity (2)

From Fertilization to Adult Sexual Behavior (1996) In our section on Molecular epigenetics, we wrote: 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 (Adler and Hajduk, 1994; de Bono, Zarkower, and Hodgkin, 1995; Ge, Zuo, and Manley, 1991; Green, 1991; Parkhurst and Meneely, 1994; Wilkins, 1995; Wolfner, 1988). That similar proteins perform functions in humans suggests the possibility…
