The end of neo-Darwinism

Rapid bacterial infection test reduces antibiotic use Excerpt: The rapid tests detect C-reactive protein (CRP), a marker of infections caused by bacteria, in patients’ blood. A low level of CRP is suggestive of viral infection and therefore antibiotic treatment is not required. My comment: The level of one protein differentiates between a viral and a bacterial infection. That fact attests to claims that one RNA-mediated amino acid substitution in a virus increases its virulence. The major antigenic changes of the…

Biophotonics, glycobiology, quantized biodiversity

Historical perspective: From Fertilization to Adult Sexual Behavior 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 (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 that some human sex differences may…

Did “Nature” kill Steve Jobs? (3)

So Many Research Scientists, So Few Openings as Professors Excerpt: Even someone as brilliant as Emmanuelle Charpentier, who in 2015 became head of the Max Planck Institute for Infection Biology after a momentous discovery in gene editing, spent the previous 25 years moving through nine institutions in five countries. My comment: Why did she move around so much when in the same year, on 07/02/2015, George Church and colleagues filed a patent application for “RNA-Guided Human Genome Engineering.” Excerpt: Repetitive…

Funding the Human Genome Project-Write

The Genome Project-Write Excerpt: …understanding of genetic blueprints could come from construction of large, gigabase (Gb)-sized animal and plant genomes, including the human genome, which would, in turn, drive development of tools and methods to facilitate large-scale synthesis and editing of genomes. To this end, we propose the Human Genome Project-Write (HGP-write), named to honor HGP-read but embracing synthesis of all large genomes. My comment: Synthesis is nutrient energy-dependent and the synthesis of all large genomes links the innate immune…

In my model of biophysically constrained energy-dependent protein folding chemistry and RNA-mediated cell type differentiation, the nutrient-dependent pheromone-controlled physiology of reproduction links the innate immune system to supercoiled DNA, which protects all organized genomes from virus-driven entropy. For comparison to my model, see: Evolution 2016 Videos (Indexed) Youtube videos Posters See also for comparison: Viruses Have Guided the Path of Human Evolution Excerpt: Whenever a viral epidemic tears through a community, there are…

Virus-driven downsizing of the human brain (2)

The effects of virus-driven energy theft on brain development in mammals typically occur more rapidly during gestation and early prenatal development. That’s why the connection from biophysically constrained RNA-mediated amino acid substitutions and protein folding chemistry during life history transitions has been largely ignored. Persistent Structural Plasticity Optimizes Sensory Information Processing in the Olfactory Bulb Excerpt: …coordinated structural plasticity is consistent with stable, yet flexible, decorrelated sensory representations. Together, our study reveals that persistent, coordinated synaptic structural plasticity between interneurons…

RNA methylation (revisited)

N 6-Methyladenosine (m6A) Methylation in mRNA with A Dynamic and Reversible Epigenetic Modification Excerpt: …the reversible and dynamic m6A RNA methylation, the most prevalent internal modification in mRNA, plays broad and key roles in diverse biological processes. Through the functional interactions with m6A methyltransferases, demethylases, and m6A-binding proteins, this epigenetic modification affects various aspects of RNA metabolism, including mRNA transcription, splicing, nuclear export, localization, translation and stability, and post-transcriptional regulate gene expression at the RNA level. Conclusion:  Indeed, breakthrough discoveries…

Placing boundaries where none exist

Epigenome-wide Association Studies and the Interpretation of Disease -Omics Reported by Carl Zimmer in:  Growing Pains for Field of Epigenetics as Some Call for Overhaul Excerpt: these experts “…argue that in some cases, changes to epigenetic marks don’t cause disease, but are merely consequences of disease. My comment: What kind of biologically uninformed expert or science journalist continues to misrepresent what is known to serious scientists about all virus-driven pathology? See for comparison: Epigenetics and Genetics of Viral Latency Excerpt:…
