One test of bioenergetic health?

human-evolution

Success of new-generation metabolo-therapies in personalized medicine depends on measuring bioenergetic health Excerpt: “In one test, a comprehensive measure of energetic health, or its disease-related deterioration, can now be made. The prognostic and diagnostic value of bioenergetic measurements in patients…

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…
