Dual Inhibition of COX‐2/5‐LOX Through Novel Hybrids of NSAIDs and Peptides: Insights from Molecular Dynamics Simulation and Per‐Residue Decomposition

ChemistryOpen, Volume 15, Issue 3, March 2026.
Hybrid NSAID–aminoacid molecules have demonstrated excellent activity in inhibiting the cyclooxygenase/lipoxygenase system. Accordingly, the present study describes the synthesis of molecules of this kind, examining their behavior via docking, molecular dynamics simulations and per‐residue energy decomposition analyses.

How New Issues Become Polarized: Partisan Triggers and Subsystem Shopping in Early AI Policymaking

Policy &Internet, Volume 18, Issue 1, March 2026.
ABSTRACT Early AI policymaking in the United States appeared bipartisan, but subsequent developments raise the question of whether AI policy will become more polarized over time. To examine how partisanship takes root around novel policy issues, we perform a mixed‐methods study, analyzing survey data from 129 state legislators in 44 states and ...

A response to ‘Quantifying phenotypic plasticity at multiple levels—A comment on Gómez et al.’

Functional Ecology, Volume 40, Issue 3, Page 560-562, March 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract In this reply, we clarify several conceptual misunderstandings raised in response to our Perspective on quantifying phenotypic plasticity. We emphasize that our central argument concerns the rigorous estimation of the magnitude of plasticity, rather than its mere ...
