From Indicator to Prediction: Five Decades of Biochemical Oxygen Demand Research in Tropical Freshwaters

open access: yesWorld Water Policy, Volume 12, Issue 4, November 2026.
ABSTRACT Biochemical oxygen demand (BOD) remains a core indicator of organic pollution in freshwater monitoring, but its role in water policy and practice is changing as water‐quality assessment moves toward predictive, integrative, and decision‐support approaches.

Chemoselective Aldehyde and Imine Reduction by a Macrocyclic Triazole–Borane Complex Triggered by a Non‐innocent Proton–Hydride Interaction

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 35, 19 September 2026.
This work describes the study on a new recyclable reagent, based on a macrocyclic triazole–borane complex. It showed high chemoselectivity for aldehyde reduction and reductive amination over ketones. This selectivity is driven by a noncovalent hydride–proton interaction that stabilizes the transition state for aldehydes but is sterically inhibited in ...

Transition Metal‐Free Vinylcyclopropanation of Olefins via Carbolithiation Reactions: Synthesis of 3‐Azabicyclo[3.1.0]hexanes

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 17, 1 September 2026.
Readily accessible N‐allyl‐N‐2‐bromoallylamines undergo a tandem lithiation–cyclization cascade to furnish highly substituted 3‐azabicyclo[3.1.0]hexanes. The transformation proceeds without transition metals and delivers products with excellent diastereocontrol across a broad substrate range.

Stereodivergent Synthesis of C5‐α‐Substituted Linezolid Derivatives From D‐Mannitol and Structure–Antibacterial Activity Evaluation

open access: yesChirality, Volume 38, Issue 9, September 2026.
A stereodivergent route from D‐mannitol enables access to enantiopure C5‐α‐substituted linezolid analogues with full configurational control. Biological evaluation reveals that α‐substitution abolishes antibacterial activity irrespective of stereochemistry, establishing a strict steric limitation at C5 and highlighting the dominant role of substituent ...

Ten rules for using evidence to guide ecosystem restoration

open access: yesJournal of Applied Ecology, Volume 63, Issue 9, September 2026.
These 10 rules provide a guidance framework to put into action the best available evidence, ensuring that restoration benefits people and nature. We highlight the importance of knowledge brokering systems in this process, effectively informed and empowered to fulfil their emerging role across existing institutions and new ones dedicated to Science ...

Factors influencing the use of scientific evidence in conservation practice and policy: Insights from a systematic map

open access: yesJournal of Applied Ecology, Volume 63, Issue 9, September 2026.
Researchers should move from characterising factors impacting scientific evidence use to identifying and testing interventions to facilitate its use by conservation decision makers. Since these factors are interlinked, implementation and testing of actions that tackle multiple barriers should be prioritised.
