“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…

Let there be anti-entropic light (1)

terrarium eco system

Summary: Light-induced amino acid substitutions link cell type differentiation in plants to nutrient-dependent pheromone-controlled reproduction in animals via the biophysically constrained chemistry of protein folding. Protein folding is perturbed by mutations that limit the ability of organisms to adapt to…

An epigenetic trap (the prequel)

terrarium eco system

See also: An epigenetic trap (the sequel) Excerpt: “Support for the link from one epigenetic trap to cell type differentiation was included in the molecular epigenetics section of our 1996 review, which detailed how RNA-mediated chromatin remodeling occurs.” My comment:…

Dual genomes: exposing the evolution industry

genetic code RNA medium

Multiple haplotype-resolved genomes reveal population patterns of gene and protein diplotypes Excerpt: “The CDP showed a significant overrepresentation of certain gene ontology (GO) groups (global tests Po0.001–0.009), using the programme FUNC23 (Methods). These groups included GPCRs, in particular olfactory receptors…

Epigenetic pharmacology and RNA-mediated transciptional landscapes

terrarium eco system

Last year, Vosshall’s group eliminated ideas about the involvement of beneficial mutations in the nutrient-dependent cell type differentiation of mosquitoes. orco mutant mosquitoes lose strong preference for humans and are not repelled by volatile DEET. This year her group showed…

More than a bag of chemicals?

neuronal-plasticity

From Fertilization to Adult Sexual Behavior (1996) 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…” My comment:…

Neuroscience Meeting Planner Now Available The Preliminary Program and Neuroscience Meeting Planner for Neuroscience 2014 are available. At the 2012 Meeting I learned that the microRNA/messenger RNA balance had emerged during the past decade to be the most likely regulator…

Creation of genes enables ecological adaptations

Genetic code

NY Times Science The Continuing Evolution of Genes By CARL ZIMMER APRIL 28, 2014 Excerpt: ” As genes duplicate over millions of years, they can grow into so-called gene families, each containing hundreds of similar genes. One family, for example, is essential for…
