Hierarchical Superposition Framework Reveals the Complex Effects of Natural Medicine Formulas

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 11, November 2025.
A novel hierarchical superposition pharmacological model incorporates the principle of hierarchical structures from physics to simulate the spatiotemporal dynamics of drug combinations, to elucidate the universal law underlying drug combination effects. By modeling cross‐level causal transmission and attenuation, it advances beyond traditional additive

Do flowers with specialized morphologies produce more nectar and pollen?

open access: yesAmerican Journal of Botany, Volume 112, Issue 11, November 2025.
Abstract Premise Flower morphology influences the architecture of plant–pollinator interaction networks. Flowers with deep corolla tubes and bilateral symmetry have a narrower pollinator range, hence are considered more specialized than shallow radial flowers. Past interspecific comparisons revealed positive correlations between flower depth and nectar
