Molecular Probes for Tracking Reactive Oxygen Species at the Organelle Interface

open access: yesAnalysis &Sensing, Volume 6, Issue 3, May 2026.
This perspective charts the frontier of visualizing compartmentalized redox signaling across mitochondria, the ER, lysosomes, and the underexplored peroxisome. It discusses evolving molecular probe designs, the integration of multiplexed imaging, and the specific engineering challenges for tracking ROS at organelle interfaces.

Metasurfaces and Metadevices for Topological Electromagnetic Waves

open access: yesAdvanced Physics Research, Volume 5, Issue 5, May 2026.
Optical topologies refer to diverse topological localized structures made by diverse parameters of light fields, such as vortices, skyrmions, and hopfions. This article navigates a direction of metasurface‐based integrated devices for generation, manipulation and detection of novel topologies of light, which would be a rapidly growing interdisciplinary

Clinical validation of a high‐definition mid‐position magnetic resonance imaging approach for lung radiotherapy planning

open access: yesMedical Physics, Volume 53, Issue 5, May 2026.
Abstract Background Respiratory‐correlated four‐dimensional (4D) magnetic resonance imaging (4D‐MRI) is useful to estimate breathing induced motion for MRI‐guided radiotherapy. Based on 4D‐MR image sets, a three‐dimensional mid‐position (MidP) MRI can be generated using deformable image registration (DIR) for radiotherapy planning. However, the desired

Comparison of Signal‐ and Volume‐Based Ventilation‐Weighted Assessment Using 3D FLORET UTE MRI in Patients With Various Pulmonary Disease

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 5, Page 2814-2827, May 2026.
ABSTRACT Purpose 3D free‐breathing, proton, contrast‐agent‐free MR methods are increasingly used for pulmonary ventilation‐weighted measurements. The methods are split between: (1) signal‐based, which rely on lung parenchyma signal changes during respiration, and (2) volume‐based that utilize the Jacobian determinant of deformation fields from the ...

Bicomponent Mapping of Cortical Bone Using a New Interleaved UTE Imaging Sequence

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 5, Page 2755-2764, May 2026.
ABSTRACT Purpose Ultrashort echo time (UTE) MRI enables direct imaging of cortical bone and quantification of its water compartments via bicomponent T2* modeling. However, conventional approaches require multiple separate dual‐echo scans due to limitations in gradient power. This approach is prone to inter‐scan inconsistencies such as motion and signal

A pipeline for megahertz X‐ray photon correlation spectroscopy on soft matter samples at the MID instrument of European XFEL

open access: yesJournal of Synchrotron Radiation, Volume 33, Issue 3, Page 725-738, May 2026.
We present a standardized and highly automated pipeline for megahertz X‐ray photon correlation spectroscopy (MHz‐XPCS) on soft‐matter samples at the MID instrument of the European XFEL. The workflow addresses AGIPD petabyte‐scale data handling, detector‐artifact correction, correlation analysis and FAIR data output, enabling routine MHz‐XPCS with ...
