Energy-dependent RNA-mediated immunity (1)

Regulatory evolution of innate immunity through co-option of endogenous retroviruses Excerpt: The analysis revealed a primate-specific element that orchestrates the transcriptional response to interferons. Selection can therefore act on selfish genetic elements to generate novel gene networks. Reported as: A copy-and-paste gene regulatory network Excerpt: Chuong et al. provide evidence that concerted processes, involving endogenous … Energy-dependent RNA-mediated immunity (1)

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

Virus-perturbed alternative splicings

Computing in mammalian cells with nucleic acid strand exchange Abstract excerpt: …we established that functional siRNA could be activated through strand exchange, and used native mRNA as programmable scaffolds for co-localizing gates and visualizing their operation with subcellular resolution. Reported as: Scientists Demonstrate Basics of Nucleic Acid Computing Inside Cells Excerpt: Cells, of course, already … Virus-perturbed alternative splicings

Hydrogen-atom transfer in DNA base pairs (5)

Can Anybody Actually Win The Evolution 2.0 Prize? January 18, 2016 at 9:44 pm In an invited review of nutritional epigenetics, I linked atoms to ecosystems without the pseudoscientific nonsense touted by neo-Darwinists. Kohl, James V. (2014): Nutrient-dependent pheromone-controlled ecological adaptations: from atoms to ecosystems. The invited submission was returned without review. When I provide … Hydrogen-atom transfer in DNA base pairs (5)

Epigenetic (re)programming of behavior (2)

|

The reports on this research bear repeating. Ants Can Change Their Roles, Study Finds Excerpt: The researchers found that certain compounds could modify proteins called histones, which affect how tightly DNA is coiled and whether certain other proteins are able to gain access to it. My comment: The molecular mechanisms of nutrient-dependent pheromone-controlled RNA-mediated amino … Epigenetic (re)programming of behavior (2)

Researchers rename, reshuffle, and reveal their ignorance

New Species Abound Re: Researchers renamed, reshuffled, and revealed species… Evidently, NEW SPECIES is part of a misleading headline placed into the context of some that EMERGED. Adapted/updated from my comments on Beyond DNA See: A Cellular System for Spatial Signal Decoding in Chemical Gradients This cellular system links the sun’s anti-entropic force and the … Researchers rename, reshuffle, and reveal their ignorance
