Brillouin–Raman micro‐mapping of silicone‐hydrogel contact lenses: Revealing chemical and mechanical heterogeneities

Journal of Microscopy, EarlyView.
Abstract Joint Brillouin–Raman micro‐spectroscopy (BRMS) enables simultaneous, non‐destructive characterisation of the mechanical and chemical properties of soft materials at the micrometre scale, combining GHz‐range viscoelastic information from acoustic modes with the vibrational fingerprint of molecular species.

Artefact‐aware Brillouin microscopy framework for root mechanical phenotyping

Journal of Microscopy, EarlyView.
Abstract Plant roots continuously sense and respond to the mechanical signals of their growth environment: root cap function, mucilage secretion, and hormonal regulation jointly adapt root tip mechanics, shaping whether roots penetrate compacted layers or reorient around obstacles. Most current measurements of root mechanical properties require removal

A Machine Learning Framework for Retrieving Atmospheric Composition and the Associated Averaging Kernels From a Geostationary Hyperspectral Infrared Sounder

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Geostationary hyperspectral infrared sounders provide hourly observations of the atmospheric composition. However, the conventional optimal estimation method (OEM)‐based retrieval algorithm requires computationally expensive radiative transfer calculations and inverse modeling, making it difficult to monitor in real time. This study presents a

SWOT Observations Reveal Basin‐Scale Reservoir Operating Patterns

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract The construction and operation of reservoirs have fundamentally modified the natural hydrograph globally. However, complex seasonal operating patterns remain opaque due to data scarcity, limiting the accuracy of hydrological modeling and water management.

Space‐Based Observation of Decadal Variations of Ammonium Sulfate Aerosols Over Northern China

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract The concentrations of ammonium sulfate, an important component of secondary inorganic aerosols, have dropped substantially in the North China Plain (NCP) over the past decade. However, current understanding of its variations is limited by the small number of ground‐based measurement sites.

SWOT Discharge Accuracy Benchmarked in South America

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract The Surface Water and Ocean Topography (SWOT) satellite mission offers unprecedented estimates of global river discharge. This study provides a first continental‐scale assessment of SWOT Consensus discharge performance across South America and compares it with a large‐scale hydrodynamic model and in situ observations.

Fast Breakdowns Observed in the Initial Leaders of Two Energetic Compact Strokes

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract We have observed 1 fast positive breakdown (FPB) and 20 fast negative breakdowns (FNBs) for the first time in the initial leader of two energetic compact strokes (ECSs) using a broadband interferometer. It was found that the FPB propagated upward over a distance of 30 m with a speed of 1.2×107m/s $1.2\times {10}^{7}\mathrm{m}/\mathrm{s ...

Toward Coherent Polaritonic Devices Operating at Room Temperature

Nanophotonics, Volume 15, Issue 17, 11 September 2026.
Polariton condensate formation and long‐range coherent transport is demonstrated using molecular exciton polaritons at room temperature (left). Waveguides and related photonic structures, such as Y‐splitters and interferometers, are realized via a focused ion beam etching of the planar microcavity. Coherent propagation of the condensate is demonstrated
