Let there be anti-entropic light (2)

Physics

Without knowing anything about the biophysically constrained chemistry of protein folding that links light-induced amino acid substitutions to the stability of DNA is the organized genomes from plants via bioluminescent bacteria in squid, the pattern of nutrient-dependent biologically-based cause and…

Forces of “Nature” (part 3)

Physics

Straight up, with a twist: New model derives homochirality from basic life requirements Excerpt:  In every living thing on Earth, all amino acids are left-handed, and all sugars are right-handed. Glycine is an achiral amino acid. It is the only…

Forces of “Nature” (part 2)

Physics

See Forces of “Nature” limit dissemination of information The policy of “Nature” to block information that conflicts with their biased reporting has led to dissemination of more pseudoscientific nonsense. This time the publication is in “PNAS” with discussion at physics…

De novo creation of olfactory receptor genes

terrarium eco system

Large-scale transcriptional profiling of chemosensory neurons identifies receptor-ligand pairs in vivo Reported as:  Deciphering the olfactory receptor code Excerpt: Its applications, countless, extend for example to the domain of chemicals able to trigger predetermined behaviors in mammals or in insects,…

Food odors and chemosignals in body odor

social interaction and brain

A Sniff of Happiness Excerpt: We observed that exposure to body odor collected from senders of chemosignals in a happy state induced a facial expression and perceptual-processing style indicative of happiness in the receivers of those signals. Our findings suggest…

Olfaction, ecology, and intelligence

rp_poster-from-jesse.jpg

“I should think we might fairly gauge the future of biological science, centuries ahead by estimating the time it will take to reach a complete comprehensive understanding of odor. It may not seem a profound enough problem to dominate all…

Hiding things about neo-Darwinism

Genetic code

Biologists devise invasion plan for mutations Excerpt:  “…researchers describe a technique for creating mutations that invade the genome and transmit themselves across to the next generation with near 100% success, defying the classic laws of Mendelian genetics.” My comment: Placed…

RNA-mediated.com (topic descriptions)

The life cycle of an mRNA in a eukaryotic cell RNA is transcribed in the nucleus processing, it is transported to the cytoplasm and translated by the ribosome. Finally the mRNA is degraded

Another companion domain has been added to the ScentofEros.com; Pheromones.com, PerfumingtheMind.com collection Intro to topics/catagories at RNA-mediated.com Information that links physics, chemistry, and molecular epigenetics from ecological variation to ecological adaptations via RNA-mediated events, such as the de novo creation…

Rejecting what is known about viral microRNAs and nutrient-dependent microRNAs

terrarium eco system

Of Cells and Limits Leonard Hayflick has been unafraid to speak his mind, whether it is to upend a well-entrenched dogma or to challenge the federal government. At 86, he’s nowhere near retirement. By Anna Azvolinsky | March 1, 2015…

Reverse phosphorylation

Genetic code

See for review: Let there be anti-entropic light (1)   Squid are hyper-editors when it comes to RNA This is a great summary of what is currently known about anti-entropic light and nutrient-dependent RNA-mediated pheromone-controlled cell type differentiation. Excerpt: “During…
