Eutrophication and phosphorylated biodiversity

In Chinese philosophy, yin and yang (also yin–yang or yin yang, 陰陽 yīnyáng “dark–bright”) describe how seemingly opposite or contrary forces may actually be complementary, interconnected, and interdependent in the natural world, and how they may give rise to each other as they interrelate to one another. Last night I dreamed that someone added color to this symbol and represented it as a spinning disk (in a publication from the Nature publishing group).  The specifics of the dream helped me…

Ricki Lewis’ Time Machine (4)

Variants near CHRNA3/5 and APOE have age- and sex-related effects on human lifespan Excerpt: The signal we observe is driven by rs429358, a non-synonymous Cys112Arg variant, which defines the ε4 allele and which has not previously been shown to be the causal variant influencing lifespan. See also: Gorilla Genome 2.0: Lessons for the Clinic? Excerpt: VARIANTS OF UNCERTAIN SIGNIFICANCE With phrases such as “settled science” and “scientific proof” part of the lexicon, it’s little wonder that health care consumers expect…

Virus-driven disorder prevention and health promotion

The dynamic epigenome and its implications for behavioral interventions: a role for epigenetics to inform disorder prevention and health promotion Excerpt: Evidence has also been growing about the role of epigenetic modification in response to the social environment. My comment: Unexpectedly, Szyf et al., (2016) fail to mention all the evidence of epigenetically-effected RNA-mediated cause and effect that has accumulated since we published our 1996 Hormones and Behavior review. That may explain why they also failed to link energy-dependent hydrogen-atom…

A two-faced protein enables RNA-mediated DNA repair (4)

See also: A two-faced protein enables RNA-mediated DNA repair (3) The importance of DNA repair to heritability cannot be understated. Theorists who think in terms of mutations and evolution are biologically uninformed and may never have learned anything about DNA repair. Serious scientists are overloaded with information and are not likely to try to explain facts about biologically based cause and effect to theorists. November, 2015 An individual-based diploid model predicts limited conditions under which stochastic gene expression becomes advantageous My…

RNA-mediated cell type differentiation and behavior

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 of all downstream effects on cell type differentiation. That inspired me to focus on what I knew about RNA-mediated events and put what we detailed about them in our 1996 Hormones and Behavior review into the context of a this…

  • What Darwin proved: there’s no such thing as a species
    GENETICS As Animals Mingle, a Baffling Genetic Barrier A short stretch of DNA is challenging what it means to be a species. By: Emily Singer August 5, 2014 Excerpt: “Scientists have dubbed such regions of the genome “islands of speciation.” The persistence of such islands is a phenomenon that has been observed in a variety of […]
