light-harvesting

From Autophagy.pro (transitions)

Summary: Who lets biologically uninformed theorists make presumptions about evolution after all serious scientists have linked light-harvesting from energy-dependent changes in electrons to ecosystems in all living genera via natural selection for food energy-dependent codon optimality. Who lets them pretend not to know that the pheromone-controlled physiology of reproduction links autophagy to the transgenerational epigenetic inheritance of healthy longevity? Who is causing the unnecessary suffering and premature death of your loved ones? Elsevier publishing supports the pseudoscientific nonsense touted by…

Creating nothing but a theory (3)

Life is physics and chemistry and communication Any model of biologically-based cause and effect must link atoms to ecosystems via the levels of organization in the diagram. That fact has been known to me since the early 1990s, when I was told that my model must start with sensory input linked to gene activation based on articles like this: Understanding the bases of sex differences Excerpt: “The articles in this issue summarize the factors surrounding sex differences with respect to…

Epigenetic effects of soil bacteria on plants

Soil Bacteria Live on Wine Grapes The earthiness of Merlot may have to do with grapevine-dwelling microbiota. By Kerry Grens | March 25, 2015 Excerpt: “…our next step is to figure out how those bacteria are affecting the chemistry of the plant.” My comment: Progress may then lead others to learn how the balance of viral microRNAs and nutrient-dependent microRNAs is linked to cell type differentiation in plants and animals via RNA-directed DNA methylation and RNA-mediated amino acid substitutions linked…

Eliminating correlations from evolutionary ecology

De novo creation of olfactory receptor genes clearly links food odors via amino acid substitutions to cell type differentiation in mosquitoes, and in nematodes, flies, honeybees, etc. It would be surprising if cause and effect did not extend to vertebrates from invertebrates. Indeed, Elekonich and Robinson (2000) linked our 1996 model of RNA-mediated cell type differentiation to hormone-organized and hormone-activated behavior in insects more than a decade ago. Since then, Vosshall’s lab has established the role that amino acid substitutions…

Forces of "Nature" limit dissemination of information

Force of nature gave life its asymmetry Excerpt: “In 2011, Meierhenrich and colleages showed4 that such light could transfer its handedness to amino acids. But even demonstrating how a common physical phenomenon would have favoured left-handed amino acids over right-handed ones would not tell us that this was how life evolved, adds Laurence Barron, a chemist at the University of Glasgow, UK. “There are no clinchers. We may never know.” My comment:I think the clincher is the creation of the…
