Energy-dependent physical and biophysical constraints (3)

See first: Energy-dependent physical and biophysical constraints (2) Emily Balskus Pins Down the Chemistry and Metabolism of Human Microbiomes Summary: The chemistry and metabolism of all microbiomes is food energy-dependent and pheromone-controlled via the physiology of reproduction. See: Feedback loops link odor and pheromone signaling with reproduction My comment to The Scientist: …trans-4-hydroxy-L-proline (Hyp) dehydratase, a newly discovered member of an abundant family of proteins, produced by gut bacteria, known as the glycyl radical enzymes, helps in metabolizing trans-Hyp, an…

Dispensing with all pseudoscientific nonsense about evolution (2)

Dispensing with all pseudoscientific nonsense about evolution (1) See also: Genomic analyses identify hundreds of variants associated with age at menarche and support a role for puberty timing in cancer risk Reported as: Hundreds of Genomic Regions Linked to Age at Menarche Age at onset of puberty is affected by a combination of genetic, nutritional, and other environmental factors and that timing, in turn, is associated with risk of cancer later in life. Who will be next to link energy-dependent…

Light ‘drives’ adaptation; nothing ‘drives’ evolution (2)

See: Light ‘drives’ adaptation; nothing ‘drives’ evolution See also: Who rules the waves? – Viruses might just be bit players in the drama of the seas. Then again, they could be major actors Excerpt (from 1996):  Most consider viruses to be a legion of cripples, sterilised by ultraviolet radiation and rendered impotent by hosts that are largely immune to their threat. But a few researchers take the opposite view. And if they turn out to be right, viruses could radically…

Effects on invertebrate GnRH and affects on primate behavior

Introduction: Energy-dependent changes in hydrogen-atom transfer in DNA base pairs in solution have again been linked to hormone-organized and hormone-activated behaviors by the conserved molecular mechanisms we detailed in the molecular epigenetics section of our 1996 Hormones and Behavior review. The practical application of those details has been reported in the context of this article, published in the New England Journal of Medicine. Effects of Testosterone Treatment in Older Men Daily Diagnosis is emailed each weekday to members of the…
