Energy-dependent chirality

See also: Achiral glycine Summary: Virus-driven energy theft alters the interactions between physics and chemistry that maintain biophysically constrained biodiversity. That’s how viruses are linked from mutations to all pathology. Nutrient energy-dependent changes in the context of the pheromone-controlled physiology of reproduction biophysically constrain biodiversity via the fixation of amino acid substitutions in supercoiled DNA, which Energy-dependent chirality

Mutisensory integration: watching the paradigm shift

Multisensory integration and causal inference in the brain Excerpt (with my emphasis):  It is largely unknown how the brain implements prior knowledge and expectations. Various mechanisms have been proposed such as spontaneous activity (Berkes et al., 2011), the fraction of neurons encoding a particular feature (Girshick et al., 2011), their response gain and tuning curves Mutisensory integration: watching the paradigm shift

Assembling yourself: Molecular self / other recognition

Chiral recognition and selection during the self-assembly process of protein-mimic macroanions Abstract excerpt: “We believe that delicate long-range electrostatic interactions could be responsible for such high-level chiral recognition and selection.” Article excerpt: “This self-assembly allows relatively simple building blocks to organize themselves into larger supramolecular structures, a phenomenon that has parallels with the formation of Assembling yourself: Molecular self / other recognition

Quantum entanglement, mass, and biomass

Joseph Kover seems closer than most other physicists to linking light-induced amino acid substitutions to cell type differentiation and biomass via the biophysically constrained chemistry of protein folding.  Today he posted notice of the following publication with the comment: “… just what I was waiting for…” Entanglement Makes Quantum Particles Measurably Heavier, Says Quantum Theorist Quantum entanglement, mass, and biomass
