Turning Electrode Orientation into a Design Parameter: Gravity‐Driven Convection for Coupling Electrochemical and Enzymatic Reactions

ChemElectroChem, Volume 13, Issue 11, 3 June 2026.
Electrochemically induced density gradients are harnessed to drive gravity‐dependent convection at partially fouled electrodes. By controlling electrode orientation and surface heterogeneity, mass transport is enhanced without external stirring. This enables coupling of electrochemical reactions with enzyme catalysis on insulating domains, exemplified ...

MYCN Amplification in RB1‐Inactivated Retinoblastoma: Association With High‐Risk Features

Pediatric Blood &Cancer, Volume 73, Issue 6, June 2026.
ABSTRACT Background MYCN amplification occurs in a subset of retinoblastoma cases, both with and without RB1 inactivation. It has been suggested that retinoblastomas with MYCN amplification represent a distinct entity with more aggressive clinical behavior.

Dual‐Targeting Cuproptosis and Mitophagy via a Flavopiridol‐Copper Nanoplatform Potentiates Immunotherapy Against Uveal Melanoma

Advanced Science, Volume 13, Issue 32, 9 June 2026.
This study develops a GSH‐responsive nanoplatform, NP@Fla‐Cu, to co‐activate cuproptosis and excessive mitophagy in uveal melanoma. The nanoplatform enhances tumor‐specific copper delivery, depletes antioxidant defenses, and remodels the tumor immune microenvironment.

Stimuli‐Responsive Hydrogels for Optical Applications: Mechanisms, Architectures, and Translational Challenges

Aggregate, Volume 7, Issue 6, June 2026.
The review discusses stimuli‐responsive hydrogels as soft optical materials that translate physical, chemical, and biological cues into refractive‐index, scattering, birefringence, diffraction, and transparency changes. It examines major stimulus classes and photonic architectures for biosensing, waveguiding, adaptive lenses, smart windows, and therapy.

Crosstalk between endoplasmic reticulum stress and mitochondrial homeostasis: A new perspective on ophthalmic disease treatment

Journal of Cell Communication and Signaling, Volume 20, Issue 2, June 2026.
The graphical abstract follows a top‐to‐bottom flow: stressors → ER–mitochondria crosstalk → ophthalmic diseases. The central panel highlights three core mitochondria‐associated membrane function axes, color‐coded as follows: light yellow for Ca2+ homeostasis, light blue for mitochondrial dynamics, and light red for mitophagy.
