Energy-dependent physical and biophysical constraints (5)

Summary: Emmy Noethe’s theorems were developed in the early 1900’s. Richard Feynman inadvertently or purposefully alluded to them as examples of human idiocy. Discover Magazine resurrected the examples of human idiocy in a 2017 article. For comparison, Choi et al., (2017) support the claims that intercellular and interkingdom communication is energy-dependent and controlled by the metabolism of food energy to pheromones. It is obvious that pheromones biophysically constrain the virus-driven degradation of messenger RNA. That fact links everything currently known…

microRNAs and species relationships

Flaws emerge in RNA method to build tree of life Study finds problems with alluringly simple way to tease out evolutionary relationships through microRNA. Amy Maxmen 28 July 2014 Excerpt 1:  “…some pieces of RNA are only expressed at particular moments in an animal’s lifetime, whereas genes in the genome are steady.” Excerpt 2): “…microRNAs cannot alone unveil species relationships.” My comment: Until earlier today, I was not aware that anyone had been touting the evolution of microRNA (miRNA) or…
