Finding it and Perfuming the Mind

Microbes Effect on the Brain Excerpt: In flies with a particular microbe, they only want to mate with others who have that microbe. This occurs because of a smell from the microbe. In groups of hyenas, groups identify their social…

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…

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…

Thermodynamic constraints and ecological adaptations sans evolution

Physics

Relationship between protein thermodynamic constraints and variation of evolutionary rates among sites Excerpt: “…a two-variable model that combines stability and stress signi ficantly improves predictions. Therefore, both the overall stability [symbol] and the stress [symbol] seem to capture distinct thermodynamic constraints on…

Physics, Chemistry, and Molecular biology (PCMb)

human-evolution

Physics, Chemistry, and Molecular biology (PCMb) link ecological variation to ecological adaptations via a model of gene-cell-tissue-organ-organ system complexity that I first presented in 1992. After adding gene activation by pheromones, I co-authored a book that linked the pheromone-controlled physiology…

Yeast Genetics Meeting

ISHE 2013 Poster photo

The “Yeast Genetics Meeting” starts 7/29/14 and presenters will establish the unequivocal fact that the epigenetic landscape is linked to the physical landscape of DNA in the organized genomes of species from microbes to man via the conserved molecular mechanisms…

Creation of genes: The holy grail of evolutionary biology

terrarium eco system

Introduction: “Deciphering the genetic mechanisms that operated during the past 650 Myr of animal evolution to create the seemingly infinite variety of animals that populate our planet has been one of the holy grails in biology.” The question arises: “How…

The smell of cancer

What Does Cancer Smell Like? By VERONIQUE GREENWOOD Published: November 19, 2013 Excerpt:  Diseases can subtly alter people’s fragrance. In the normal course of metabolism, thousands of waste products are swept out in our breath, blood and urine, or simply…

Similarities spur a radical rewrite of human evolution

social interaction and brain

Hominid Skull Spurs Radical Rewrite of Human Evolution By Gemma Tarlach October 17, 2013 1:00 pm Excerpt: “…variations between the skull and those of other early hominids found at the site are no more significant than differences among modern humans,…
