Exploring Biological Properties of Manganese(II)‐Phenanthroline‐Based Complexes: In Vitro Insights

open access: yesChemistrySelect, Volume 11, Issue 29, 3 August 2026.
Four Mn(II) complexes with phenanthroline derivatives were studied. These compounds were tested against several parasites and different human cancer cells. Despite its cytotoxicity on breast cancer, DNA seems not to be the main biological target. These complexes can drive the design and development of new metal‐based agents with improved biological ...

Methane and Nitrous Oxide Reshape the Air‐Water Greenhouse Gas Budget of a Tropical Estuarine Delta

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 7, July 2026.
Abstract Estuaries are important sources and sinks of greenhouse gases (GHGs), yet assessments of their radiative balance often focus primarily on carbon dioxide (CO2), with less attention given to methane (CH4) and nitrous oxide (N2O). We combine measurements of CH4 and N2O air‐water fluxes with concurrent CO2 data in a tropical estuarine delta ...

Antioxidants in Plant‐Based Food Matrices: From Structure–Activity and Degradation Kinetics to Formulation Design

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 4, July 2026.
ABSTRACT Plant‐based antioxidants are widely incorporated into foods to retard oxidative deterioration and to deliver health‐related benefits. Yet, their in‐product and in vivo performance frequently diverges from predictions based on solution‐phase chemical assays, because matrix interactions, processing history, and host metabolism reshape both ...

Climate Predicts Tree Dispersal Strategies Across Brazil's Ecosystems

open access: yesGlobal Ecology and Biogeography, Volume 35, Issue 7, July 2026.
ABSTRACT Aim We investigate the distribution of dispersal modes—endozoochory (via animal ingestion), synzoochory (via animal seed accumulation) and anemochory (via wind)—and seed mass of woody plants across Brazilian ecosystems, testing whether their relative abundance in local plant communities could be predicted by climate, edaphic factors and ...
