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…

Understanding cell type differentiation

Genetic code

The Wisdom of the Fly Crowds by Ed Yong Excerpt: “This is a landmark study of collective behaviour,” says Iain Couzin… “Never before has it been possible to unweave the intricate coding of social behaviour during collective decision-making.” When it…

Thermodynamic constraints and ecological adaptations sans evolution

Physics

Relationship between protein thermodynamic constraints and variation of evolutionary rates among sites Excerpt: “…a two-variable model that combines stability and stress signi ficantly improves predictions. Therefore, both the overall stability [symbol] and the stress [symbol] seem to capture distinct thermodynamic constraints on…
