Laser bathymetry on rough riverbed channels: State‐of‐the‐art and future prospects

Earth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.
This literature review found that topo‐bathymetric LiDAR has been successfully used to capture the structures of rough riverbeds and detect large boulders. While all of the studies that were reviewed used sensors that were operated from fixed‐wing aircraft, few studies have yet tested UAV‐borne sensors on rough riverbeds, despite the potential offered ...

Developmental Profiling of Structural and Functional Maturation in Mouse Corpus Callosum

Glia, Volume 74, Issue 6, June 2026.
Progressive myelin development in mouse corpus callosum is accompanied by gradual decrease in oligodendrocyte precursor cell density and increase in oligodendrocyte density. Pro‐Capase‐3 is transiently upregulated in oligodendrocyte during postnatal development.

Nonlinear Imaging Allows to Characterize Granulomas and Fibrosis in Mice Tissue From Experimental Schistosomiasis

Journal of Biophotonics, Volume 19, Issue 6, June 2026.
Second Harmonic Generation and Two‐Photon Excitation Fluorescence microscopy allows to characterize mice tissues infected with Schistosoma mansoni in an experimental model. ABSTRACT Schistosomiasis is a neglected disease caused by parasites of the genus Schistosoma that poses serious public health problems.

Feasibility of In Vivo Retinal Flavoprotein Autofluorescence Imaging in a Magnetic‐Bead‐Induced Rodent Glaucoma Model

Journal of Biophotonics, Volume 19, Issue 6, June 2026.
A scanning laser ophthalmoscope, integrated with a real‐time optical coherence tomography (OCT) alignment monitor, detected flavoprotein fluorescence (FPF) signals associated with mitochondrial dysfunction in a rodent glaucoma model. Under 450‐nm excitation, experimental eyes showed spatially inhomogeneous signals that were absent under 505‐nm ...

Automated Imaging of Cultured Bacteria in Picoliter Droplets by Coherent Anti‐Stokes Raman Scattering and Two‐Photon Excited Fluorescence Microscopy

Journal of Raman Spectroscopy, Volume 57, Issue 6, Page 1071-1080, June 2026.
We present an automated system that combines an image‐based fuzzy logic controller for precise positioning of microfluidic picoliter droplets with nonlinear microscopy, using CARS and TPEF modalities for detailed analysis of droplet composition. Time series and z‐stack images of E. coli, B. subtilis, and M. arborescens were recorded.
