An Idea to Explore: From How to Why: Using Evolutionary Biochemistry to Inspire Biochemistry Education

open access: yesBiochemistry and Molecular Biology Education, EarlyView.
ABSTRACT Traditional biochemistry instruction often emphasizes mechanistic detail, that is, how molecules and pathways function, without equally addressing why they have their present forms. This fact‐centered approach can leave students overwhelmed and disconnected from the broader scientific narrative.

Turning Green Into Gold: The Impact of Green Intellectual Capital on Performance in European Firms

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study examines the impact of green intellectual capital (GIC)—green human, structural and relational capital—on business performance in European firms. Using Eurobarometer 498 data and Partial Least Squares Structural Equation Modelling (PLS‐SEM), results show that GIC explains 15.4% of the variance in business performance, with green ...
