Molecular Diagnostics: What is unprotected life?

Facile Recoding of Selenocysteine in Nature Abstract excerpt: This illustrates the ease by which the genetic code may evolve new coding schemes, possibly aiding organisms to adapt to changing environments, and show the genetic code is much more flexible than previously thought. My comment: It also refutes the ridiculous theories of neo-Darwinists, by placing ecological variation and ecological adaptation into the context of how nutrient-dependent RNA-mediated events are linked from the innate immune system to the physiology of reproduction and…

Ricki Lewis’ Time Machine (3)

See also: Ricki Lewis’ Time Machine Ricki Lewis Time Machine (2) DNA video in real time. Show the amazing process of DNA transcription using amino acids to turn genes into proteins. My comment: The amino acids are nutrient-dependent and linked to supercoiled DNA by energy-dependent changes in the innate immune system. The innate immune system links metabolic networks and genetic networks to supercoiled DNA. The fact that the amino acid substitutions link the innate immune system to all biodiversity in…

Creating nutrient-dependent life with enough genes to survive (2)

See also: Creating nutrient-dependent life with enough genes to survive Minimal Genome Created Excerpt 1) “In biology, as we’ve been trying to do genetic and biological engineering, we’re frustrated by the fact that . . . evolution has given us a real mess—it’s really just bubble gum and sticks, piecing together whatever works,” said biomedical engineer Chris Voigt of MIT who was not involved in the study. “This [work] is one of the first attempts at a grand scale to…

Creating nutrient-dependent life with enough genes to survive

Design and synthesis of a minimal bacterial genome Excerpt: Cells are the fundamental units of life. The genome sequence of a cell may be thought of as its operating system. It carries the code that specifies all of the genetic functions of the cell, which in turn determine the cellular chemistry, structure, replication, and other characteristics. Each genome contains instructions for universal functions that are common to all forms of life, as well as instructions that are specific to the…

Confusing effects and affects of visual input

Their report indicates that these researchers never learned to differentiate between epigenetic effects on RNA-mediated cell type differentiation compared to the experience-dependent affects on behavior of amino acid substitutions. Experience Affects Critical Period Plasticity in the Visual Cortex through an Epigenetic Regulation of Histone Post-Translational Modifications Excerpt: We show that the early exposure of rat pups to enriching environmental conditions accelerates the critical period for plasticity in the primary visual cortex, linking this effect to increased histone acetylation, specifically at…

Selective reporting of inferences: examples of pseudoscience

In the narrative of this presentation on RNA mediated molecular epigenetics and virus driven entropy, I mentioned that Cori Bargmann is scheduled to deliver a lecture entitled “Genes, neurons, circuits and behavior: an integrated approach in a compact brain.” An integrated approach will help others understand what is currently known about how ecological variation leads to ecological adaptation. Works, like hers, with the nematode model organism will help others understand how ecological adaptation leads to biodiversity in the morphological phenotypes…

Science vs semantics

Re-interpreting long-term evolution experiments — Is delayed adaptation an example of historical contingency or a consequence of intermittent selection? Excerpt: “… the series of events used to explain adaptation in the short-transfer LTEE (and in speciation) might need to be revised. The amplification model supported by this article has already be proposed as a means of evolving new genes (1) and has been experimentally shown capable of generating a novel genetic function within as few as 3000 cell generations (11).…

Bacteria see the light and they adapt (2)

Differential Odour Coding of Isotopomers in the Honeybee Brain Conclusion: In summary, we provided the first neurophysiological evidence of differential neural coding of isotopomers. Also, in light of the recent literature on ODEs, and considering that odour transduction in insects occurs in ≈2 ms24, it seems unlikely that perireceptor events could be responsible for the reported isotope sensitivity. Finally, we performed direct measurements of the vibrational spectra of each odorant, and reported that spectral differences among isotopomers well reflect differences in…

    GENETICS As Animals Mingle, a Baffling Genetic Barrier A short stretch of DNA is challenging what it means to be a species.
