Hydrogen-atom energy in DNA base pairs

See also: Consciousness is simply food rearranged Role of Double Hydrogen Atom Transfer Reactions in Atmospheric Chemistry Abstract excerpt:  Hydrogen atom transfer (HAT) reactions are ubiquitous and play a crucial role in chemistries occurring in the atmosphere, biology, and industry. My comment: The link from physics to chemistry and the conserved molecular mechanisms of biologically-based RNA-mediated cell type differentiation has been the focus my works for more than 20 years, even before I knew what I would need to explain…

The Aquatic Ape: New evidence?

The Waterside Ape BBC Radio 4 Publicity Sir David Attenborough considers whether new evidence will help a once widely ridiculed theory of human origins move towards to mainstream acceptance. In 1960, the eminent Oxford marine biologist Sir Alister Hardy proposed a revolutionary idea: that our human ancestors had not started their existence on the wide savannahs of Africa, but had become accustomed to living alongside water – swimming and diving in the shallows, collecting the abundant food, and learning to…

From angstroms to ecosystems

How a happy moment for neuroscience is a sad moment for science Systems neuroscience is celebrating a landmark, but one that shows the way we do science is broken. Excerpt: These data are the first complete set of neural activity recordings released before publication. No papers preceded it; not even a report. Nothing. Just: here you go guys, the fruits of the joint labour of around 100 people over 4 years.” My comment: They released the information on June 13,…

Energy-dependent RNA methylation (9)

Epigenetics and How Our Decisions Affect Our DNA Excerpt (with my emphasis): With the Genetics and Genomics 2016 virtual conference now on demand, we are extending the genetics conversation into this month with a new infographic. Epigenetics has been in the news quite a bit lately as researchers have been able to learn more about its process and influences. It turns out that epigenetics is an ever-changing process within our cells, causing more rapid modification within a generation. Unlike standard…

Energy-dependent RNA methylation (6)

After I published Nutrient-dependent/pheromone-controlled adaptive evolution: a model, Lynnette Ferguson and Justin O’Sullivan invited me to submit this review of nutritional epigenetics for inclusion in a special issue of the journal “Nutrients.” Nutrient-dependent pheromone-controlled ecological adaptations: from atoms to ecosystems (April 10, 2014) Abstract: This atoms to ecosystems model of ecological adaptations links nutrient-dependent epigenetic effects on base pairs and amino acid substitutions to pheromone-controlled changes in the microRNA / messenger RNA balance and chromosomal rearrangements. The nutrient-dependent pheromone-controlled changes…
