Deep Learning‐Assisted Coherent Raman Scattering Microscopy

Advanced Intelligent Discovery, Volume 2, Issue 4, August 2026.
The analytical capabilities of coherent Raman scattering microscopy are augmented through deep learning integration. This synergistic paradigm improves fundamental performance via denoising, deconvolution, and hyperspectral unmixing. Concurrently, it enhances downstream image analysis including subcellular localization, virtual staining, and clinical ...

Red‐to‐Near‐Infrared Fluorescence Resonance Energy Transfer Reporters for Dual Imaging Applications

Small Methods, Volume 10, Issue 15, 7 August 2026.
Genetically encoded FRET biosensors reveal dynamic signaling in living cells, but overlapping spectra have limited the simultaneous monitoring of multiple pathways. We introduce a red‐to‐near infrared FRET pair, mRuby2/miRFP670nano3, compatible with existing reporters and enabling dual FLIM‐FRET without bleed‐through.

SMILE: Extraction‐free submicron‐resolution mapping of lipid chain length and unsaturation by stimulated Raman imaging

VIEW, Volume 7, Issue 4, August 2026.
In this work, we develop submicron‐resolution mapping of intracellular lipid elements (SMILE) as an extraction‐free vibrational spectroscopic imaging platform based on hyperspectral stimulated Raman scattering microscopy with a spectral analysis pipeline for pixel‐resolved lipid profiling.

Remote Sensing During the 2025 Los Angeles Wildfires

AGU Advances, Volume 7, Issue 5, August 2026.
Abstract The January 2025 Los Angeles County wildfires burned more than 50,000 acres, destroyed more than 16,000 structures, and caused 31 deaths. This Commentary examines how NASA's Disasters Program coordinated with response organizations to deliver 22 satellite and airborne products during the fires, even as the Eaton Fire forced the Jet Propulsion ...

Visible and Near Infrared (VNIR) Spectroscopy to Decipher Glass and Crystal Content of Lab‐Made Martian Volcanic Analogs

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract Understanding how the glass/crystal ratio influences the spectral response of volcanic rocks is crucial for interpreting planetary remote sensing data. Here, four mafic rocks simulating a possible Martian composition were synthesized with identical bulk chemistry but different mineralogical assemblages, from fully amorphous to ∼70 wt.% crystal
