Soil bacteria, bulls, cows, microRNAs, and mammary glands

What is Life? Excerpt:  Indeed, in the case of higher animals we know the kind of orderliness they feed upon well enough, viz. the extremely well-ordered state of matter in more or less complicated organic compounds, which serve them as foodstuffs. After utilizing it they return it in a very much degraded form -not entirely degraded, however, for plants can still make use of it. (These, of course, have their most power supply of ‘negative entropy’ the sunlight) My comment:…

Hybrids: making microbes and Democrats into monkey’s uncles?

Darwinists Underestimate Nature. Creationists Underestimate God. Excerpt: Doug, here’s what we know: Two processes produce new species in real time – 1) Hybrids, where Species 1 crossed with Species 2 gives you Species 3. Example: Emmer wheats + goat grass = modern wheat. This doubles the number of chromosomes. After this merger, “hybrid dysgenesis” kicks in. Extensive genome editing re-arranges and deletes parts of the new DNA. Genome studies indicate that a hybridization event of this kind got us from…

Will modern human populations adapt to the Zika virus?

Jurassic ‘butterflies’ predated true butterflies by 50 million years Excerpt: The researchers analyzed 20 kalligrammatid fossils (like the one pictured at right), and found striking similarities to butterflies (like the owl butterfly at left). My comment: These striking similarities must link energy-dependent hydrogen-atom transfer in DNA base pairs in solution to RNA-mediated amino acid substitutions and all biodiversity in primate morphological and behavioral phenotypes via what is currrently known about the claim that Dobzhansky made in 1973. “…the so-called alpha…

Models of scientific literacy

Scientific Literacy Redefined Researchers could become better at engaging in public discourse by more fully considering the social and cultural contexts of their work. By Cynthia Brandenburg | February 1, 2016 Excerpt: …any truly productive conversation about why their fears are scientifically unfounded must be predicated upon an understanding of what caused those fears in the first place. My comment: “A Fear of Pheromones” led many researchers to ignore the fact that metabolic networks must be linked to genetic networks…

Blood test links atoms to ecosystems

New blood test may expand scope of liquid biopsies Excerpt: During cell death, the DNA gets chopped into small pieces by enzymes that like to cut in the easily accessible, unprotected sections of DNA in between the nucleosomes. My comment: The test links ecological variation to nutrient-dependent RNA-mediated DNA repair via microRNAs and adhesion proteins. The adhesion proteins link supercoiled DNA to protection from virus-driven entropy in the organized genomes of all living genera. The organized genomes are linked from…

Juvenile hormone links atoms to ecosystems

A comparative perspective on epigenetics Excerpt 1) …adaptation and evolution emerge through network-wide responses to change at all levels of biological organisation, from proteins and membranes to organelles and cells, rather than being driven by individual genes. ‘Active causation resides in the networks, which includes many components for which there are no DNA templates’, says Noble, concluding that this novel approach provides ‘an integrated systems view of evolution’. Excerpt 2) ‘Active causation resides in the networks, which includes many components…

Teleophobes vs teleophiles: a recent history

  Teleology is a reason or explanation for something in function of its end, purpose, or goal. The teleological or physico-theological argument, also known as the argument from design, or intelligent design argument is an argument for the existence of God or, more generally, for an intelligent creator “based on perceived evidence of deliberate design in the natural or physical world” My comment: Teleophobes make weak arguments peppered with logical fallacies.  They do not make physico-theological arguments, which can be supported…

Genes, orchid odors, and pheromones from blonds

1) The Genetics of Blond Hair (2014) and 2) Orchids give off human ‘body odor’ to attract mosquitoes (2016) Both articles link RNA-mediated cell type differentiation in all invertebrates and all vertebrates to every aspect of cell type differentiation in plants. …studies of genetic variation in thousands of people have linked at least eight DNA regions to blondness based on the fact that a certain DNA letter, or base, was found in people with that hair color but not in…

NORAD: air defense and defense against genomic entropy

NORAD may refer to: North American Aerospace Defense Command… that provides aerospace… defense for North America Norwegian Agency for Development Cooperation Noradrenaline, a hormone and a neurotransmitter with multiple biological roles My comment: The modern use of radar includes air-defense systems and ocean surveillance systems.  High tech radar systems are designed to use the systems complexity of signaling and sensing to extract useful information from levels of very high noise.  In the context of protection from virus-driven genomic entropy use…

Manufacturing fossil “evidence”

An antagonist suggests that it is appropriate to use math models to fill in the analagous missing dots, which in this case involved manufacturing evidence to be included in the fossil record. ‘Virtual fossil’ reveals last common ancestor of humans and Neanderthals My comment: Serious scientists do not use math models to link atoms to ecosystems. They use what is known about physics, chemistry, and conserved molecular mechanisms. Similarly, they do not introduce analogies or metaphors as substitutes for experimental…
