Rational Modulation of Excited‐State Intramolecular Proton Transfer, Aggregation‐Induced Emission, and Intramolecular Motion on Polysubstituted Imidazoles

open access: yesChemPhotoChem, Volume 10, Issue 1, January 2026.
Precise modulation of the excited‐state intramolecular proton transfer (ESIPT) process was achieved using a newly synthesized family of N‐substituted imidazoles. Combined experimental and theoretical approaches reveal how N‐alkyl and 2‐(methoxy)phenyl modulate enol‐keto equilibrium, molecular conformation, and emission behavior.

Water Parameters and Hydrodynamics in Rivers and Caves Hosting Astyanax mexicanus Populations Reveal Macro‐, Meso‐ and Microhabitat Characteristics

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
From 2009 to 2025, we have recorded the physicochemical parameters of the water and the hydrological regimes at localities hosting Astyanax mexicanus cavefish and surface fish populations in Mexico. Sampling 13 caves and 30 surface stations revealed strong signatures of the two macrohabitats, but also significant differences in specific water ...

Natural Products Targeting Notch Signaling in Cancer: Mechanistic Insights and Food‐Based Chemoprevention Potential

open access: yesFood Frontiers, Volume 7, Issue 1, January 2026.
The Notch signaling pathway plays a dual role in cancer, acting as both a tumor promoter and suppressor depending on cellular context. This review highlights how natural products modulate Notch signaling to inhibit tumor initiation, progression, angiogenesis, and cancer stem cell maintenance.
