A Comparative Study of MALDI MSI Versus DESI MSI Applied to Questioned Document Examination

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 19, 15 October 2026.
ABSTRACT Rationale In forensic investigations, questioned document examination (QDE) provides critical information for document authentication and the detection of forgeries. Conventional QDE approaches often require separate analyses of inks and of any potential fingerprints.

Müller Glia–Vasculature Interactions in the Developing Retina

open access: yesGlia, Volume 74, Issue 10, October 2026.
Retinal vascular layers form normally despite loss of cholinergic retinal waves. Müller glial processes contact endothelial tip cells early and form Aquaporin‐4‐enriched endfeet. Glial endfoot calcium signals are compartmentalized and occur largely independently of neural activity. ABSTRACT Coordinated signaling among neurons, glia, and the vasculature

Gq Signaling in Microglia Triggers Interferon Responses and Improves Outcome After Ischemic Stroke

open access: yesGlia, Volume 74, Issue 10, October 2026.
Chemogenetic activation of Gq signaling in microglia ahead of ischemic stroke reduces infarct size in mice. Seven days after stroke, Gq‐primed microglia in the penumbra show enhanced interferon responses, altered branching patterns, and reduced phagocytosis.

Simultaneous T2, T2*, and R2′ Mapping for Multiple Sclerosis Using Nonlinear Model‐Based Reconstruction of Undersampled Radial RARE‐EPI MRI

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 4, Page 1872-1892, October 2026.
ABSTRACT Purpose To demonstrate the synergy of undersampled radial 2in1‐RARE‐EPI acquisition and nonlinear model‐based reconstruction for accelerated and simultaneous T2, T2*, and R2′ mapping in brains of patients with multiple sclerosis (MS). Methods 2in1‐RARE‐EPI combines a RARE module with an EPI module to capture T2 and T2* information.

Fish Scales: A Multifunctional Biomaterial from Nature

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 5, September 2026.
Fish scales demonstrate nature's solution to impact protection through overlapping multilayered architecture. This biological design combines mineralized surfaces with collagen networks to achieve both flexibility and fracture resistance. The structural principles inspire advanced protective materials and biomedical implants, where damage tolerance ...
