Refusing to integrate neuroendocrinology and ethology

Q&A: Karl Grammer Excerpt: We and others have identified eight pillars of beauty: youthfulness, symmetry, averageness, sex-hormone markers, body odour, motion, skin complexion and hair texture. I think this line of research is almost finished. It is no longer useful…

Pheromone-induced odour learning

social interaction and brain

Mammary pheromone-induced odour learning influences sucking behaviour and milk intake in the newborn rabbit Excerpt: “…several results showed that pups could learn different odorants during successive days of conditioning, and that the more recently acquired cue was the most influential…

Let there be anti-entropic light (2)

Physics

Without knowing anything about the biophysically constrained chemistry of protein folding that links light-induced amino acid substitutions to the stability of DNA is the organized genomes from plants via bioluminescent bacteria in squid, the pattern of nutrient-dependent biologically-based cause and…

Science fiction, not theories, predicts facts

The past is not the key to the present

Electric fields affect wing movement, leading to agitation and changes in brain chemistry Excerpt: The effect on the wings being moved seems to agitate the flies, as revealed by changes in their brain chemistry. Flies exposed to an electric field…

Finding it and Perfuming the Mind

human-brain

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…

Et tu, Michael Stoddart

terrarium eco system

How our NOSE shaped the human race: Ancestors lost their ability to detect sex pheromones to make men more faithful – and create the stable family unit Excerpt: “Our sense of smell evolved to make human pheromones undetectable” For contrast…

Discoveries in 3-D Genome Make-Up and Genetic Changes: Clarification of differences amidst chromosome pairs and how gene expression is effected by chromosome folding Excerpt: “…offers a useful guide for future studies of the epigenome’s function in our evolution and diseases…

Insect homology and diversity attributed to mutations

Genetic code

Ancient homology underlies adaptive mimetic diversity across butterflies Excerpt: “Surprisingly, our results suggest that modulation of this conserved developmental gene has occurred in tandem between these two deeply divergent butterfly lineages, implying an unexpected and remarkable level of predictability in…

Comparing divergent model organisms

Genetic code

Comparative analysis of the transcriptome across distant species Excerpt: Overall, our results underscore the importance of comparing divergent model organisms to human to highlight conserved biological principles (and disentangle them from lineage-specific adaptations). My comment: In the detailed comparisons of…
