Siloxane‐Activated Through‐Space Conjugation in Conventional Chromophores for Dual‐State Emission

Aggregate, Volume 7, Issue 5, May 2026.
Siloxane‐activated through‐space conjugation (TSC) in polymer chains creates dual‐state emissive materials. Through a “dynamic encapsulation” mechanism, siloxane linkages organize chromophores into non‐covalently coupled assemblies, yielding high quantum yields.

Graph Neural Network in Raman Spectroscopy to Leverage the Performance and Interpretability of the Classification

Chemistry–Methods, Volume 6, Issue 5, May 2026.
Graphic neural networks are constructed for Raman‐based biomedical applications after transferring Raman spectra into graph representations, i.e., nodes and edges. The classification is observed to provide better robustness against disturbing spectral variations such as device‐to‐device differences.

Resilience to Cardiac Aging in Greenland Shark Somniosus microcephalus

Aging Cell, Volume 25, Issue 5, May 2026.
Greenland shark Somniosus microcephalus shows severe cardiac aging such as fibrosis, lipofuscin buildup, mitochondrial damage, and oxidative stress, unseen in comparison species Etmopterus spinax and Nothobranchius furzeri, yet remain healthy. S. microcephalus resilience suggests unique mechanisms that preserve heart function for centuries, offering ...

The MICOS Complex Regulates Mitochondrial Structure and Oxidative Stress During Age‐Dependent Structural Deficits in the Kidney

Aging Cell, Volume 25, Issue 5, May 2026.
During kidney aging, loss of the MICOS complex drives cristae disorganization, impairs oxidative capacity, and alters mitochondrial dynamics. MICOS disruption elevates mitochondrial ROS and disrupts calcium homeostasis, linking mitochondrial structural remodeling to metabolic dysfunction in aging kidney tissue.

Molecular pathology of phyllodes tumours of the breast—much more than MED12

Histopathology, Volume 88, Issue 6, Page 1115-1125, May 2026.
Phyllodes tumours can develop from fibroadenomas bearing MED12 variants by the development of pTERT alterations (“MED12 pathway”) or de novo (“MED12 independent pathway”). Grade progression is associated with increasing genetic complexity including cancer driver gene aberrations. Molecular alterations can be useful in assigning grade and distinguishing

Electron microscopy‐based three‐dimensional subcellular imaging of plant male gametophyte

Journal of Integrative Plant Biology, Volume 68, Issue 5, Page 1290-1314, May 2026.
The Aquilos2 Cryo‐FIB workflows provide practical routes for cryo‐electron tomography and volume imaging in plant structural biology. ABSTRACT Understanding cellular events in three dimensions (3D) is of great importance for the annotation and illustration of biological processes in a contextual way. Imaging techniques based on electron microscopy (EM),

Simulations of a High Ozone Episode and Heatwave Day Using a Coupled Multi‐Layer Urban Canopy and Chemistry Model

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract Coastal cities face critical challenges in managing ozone pollution because of high population density and complex interactions between urbanization and coastal meteorology. Using New York City (NYC) as a case study, this work examines how urban surfaces influence heatwaves, sea‐breeze circulations, and boundary‐layer dynamics, and how these ...
