Piperazine and Morpholine Protoporphyrin IX Derivatives Intensify Biomolecules Oxidation and Phototoxicity in Triple‐Negative Breast Cancer

ChemMedChem, Volume 21, Issue 17, 14 September 2026.
Protoporphyrin IX derivatives bearing piperazine or morpholine substituents exhibit enhanced cellular retention and photodynamic activity in triple‐negative breast cancer cells. Structural modification promotes oxidative stress, alters mitochondrial membrane potential, and increases caspase‐3 activity, providing new structure–activity relationship ...

Influence of Octenyl Succinic Anhydride Modification on Physicochemical and Functional Properties of Rice Starches With Varying Amylose Content

Starch - Stärke, Volume 78, Issue 9, September 2026.
Amylose content governs OSA reactivity and starch functionality. OSA modification reduces amylose and promotes amylose‐dependent substitution, lowering gelatinization temperature and altering pasting behavior while improving stability and amphiphilicity.

Scaling from microsite to landscape to resolve litter decomposition dynamics in globally extensive drylands

Functional Ecology, Volume 40, Issue 9, Page 2726-2736, September 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

From individuals to networks: The role of variation in plant–pollinator communities' responses to global change

Journal of Animal Ecology, Volume 95, Issue 9, Page 1586-1597, September 2026.
This paper argues that variation among individuals—not just species differences—can shape the sensitivity, robustness and resilience of plant–pollinator communities under global change. By linking individual traits and interaction structure to network dynamics, it provides a new framework and future research directions for predicting community ...
