Sulfated steroids and RNA-mediated identity codes

terrarium eco system

Summary: In two studies of human pheromones we linked a mixture of androsterone and androstenol to increased flirtatious behavior and reports of increased attraction to the male wearing the mixture. This blog posts explains the reason for the use of…

Modeling conserved microRNA expression

translocated chromosome

Insects as models to study the epigenetic basis of disease Excerpt: “…selected insects can be used as models for human diseases with an epigenetic component because the underlying molecular mechanisms (DNA methylation, histone acetylation and the expression of microRNAs) are…

Theoretical physics and molecular biology

terrarium eco system

Astrophysical phenomenology meets pheromone-ology: Slugs that “eat light” Theoretical physics and molecular biology can be compared in the context of their explanatory power. For example (with my emphasis): Theoretical physics (2015): Firewall Phenomenology with Astrophysical Neutrinos Abstract: One of the…

Atoms to ecosystems is not almost a molecular ecology

terrarium eco system

In Kohl (2012) I wrote: Among different bacterial species existing in similar environments, DNA uptake (Palchevskiy & Finkel, 2009) appears to have epigenetically ‘fed’ interspecies methylation and speciation via conjugation (Fall et al., 2007; Finkel & Kolter, 2001; Friso &…

Quantum physics, quantum biology, and quantum consciousness

human-evolution

Has anyone but me attempted to link light-induced amino acid substitutions from quantum physics to quantum biology in the context of the following works? All five published articles appear to be linked to quantum consciousness by the chemistry of nutrient-dependent…

Removing natural selection; reshaping the horse; adjusting evolutionary theory

human-evolution

Prehistoric genomes reveal the genetic foundation and cost of horse domestication Reported as: Reshaping the horse through millennia Excerpt: “Domestication is generally associated with repeated demographic crashes. Yet, mutations that negatively impact genes are not eliminated by selection and can even…
