Achromobacter and killer theories

A pan-genomic approach to understand the basis of host adaptation in Achromobacter  Ecological variation is linked to food energy-dependent biophysically constrained viral latency by the pheromone-controlled physiology of reproduction in species from microbes to humans. For comparison, these authors claim: This study provides strong phylogenetic and pan-genomic bases to motivate further research on Achromobacter, and Achromobacter and killer theories

Food energy-dependent cell type differentiation (2)

Summary: The concept of “faster-evolving DNA” regions in the context of nucleotide variation in both the 16S and 12S sequences is not consistent with any accurate representation of how the functional structure of supercoiled DNA must be linked from energy-dependent changes in angstroms to ecosystems in all living genera. Conserved molecular mechanisms link the sense Food energy-dependent cell type differentiation (2)

Virulence and your UTI

Nobody wants to belong to the party of losers. One of the best strategies in such a case is evidently an interpretation of the change as a gradual accumulation of knowledge while their work has always been at the cutting edge. — Kalevi Kull Virulence: Take on the role of a virus competing to infect Virulence and your UTI

Life is energy-dependent task management (2)

See: Life is energy-dependent task management See also: New device detects bacteria and tests for antibiotic resistance When bacteria are caught, the device sends out three different signals to researchers. When bacteria is detected the cantilever’s mass changes, and it bends, explained Thomas Thundat, a professor in the Department of Chemical and Materials Engineering and Life is energy-dependent task management (2)

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 Base pairs, olfaction and RNA thermometers

Model vs theory: Progress report!

On June 14, 2013, 1) Nutrient-dependent/pheromone-controlled adaptive evolution: a model and 2) Mutation-Driven Evolution were published with divergent/opposite conclusions. 1) …the largest contributor to the development of our personal preferences may be the unconscious epigenetic effects of food odors and pheromones on hormones that organize and activate behavior. If so, the model represented here is Model vs theory: Progress report!

Ricki Lewis’ Time Machine

Can a Quirky Chromosome Create a Second Human Species? Excerpt 1) The first departure from the common house mouse (Mus musculus) was the “tobacco mouse” (Mus poschiavinus), described in 1869 from specimens trapped in a tobacco factory in Valle di Poschiavo, Switzerland. They had big heads and small, dark bodies. Excerpt 2) I spoke to Bear Ricki Lewis’ Time Machine
