Stabilization of the Benzene Radical Trianion in an Inverse‐Sandwich Yttrium Complex

Angewandte Chemie, Volume 138, Issue 13, 23 March 2026.
A new type of benzene anion state is born: The unprecedented benzene radical trianion embedded in an inverse‐sandwich yttrium complex was synthesized by a one‐electron chemical reduction of its benzene dianion precursor using potassium graphite in the presence of [2.2.2]‐cryptand.

Real‐Time Monitoring of Enzyme Conformational Transitions During Substrate Inhibition via Nanopipettes

ChemElectroChem, Volume 13, Issue 7, 1 April 2026.
A label‐free nanopipette platform is used to monitor acetylcholinesterase (AChE) at the single‐molecule level during substrate inhibition. Distinct ionic current signatures reveal a nonmonotonic transition corresponding to mono‐ and bisubstrate binding, directly linking substrate occupancy to real‐time enzyme conformational expansion and compaction ...

GloMarGridding: A Python Toolkit for Flexible Spatial Interpolation in Climate Applications

Geoscience Data Journal, Volume 13, Issue 2, April 2026.
Global surface climate datasets contain structural uncertainty that is difficult to attribute to individual processing steps. We present GloMarGridding, a Python package that isolates the spatial interpolation component using Gaussian Process Regression (or kriging) to generate spatially complete fields and uncertainty estimates. The techniques used in

Measurement of Phase Velocity and Ellipticity of Multi‐Mode Surface Waves by Beamforming Multi‐Component Ambient Seismic Noise

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Conventional beamforming of multi‐component ambient seismic noise typically utilizes only the vertical‐vertical (ZZ) component to extract Rayleigh wave dispersion curves or the transverse‐transverse (TT) component for Love waves. In this study, we extend weighted and modified beamforming to cross‐correlation functions between different ...

The second moment of sums of Hecke eigenvalues II

Journal of the London Mathematical Society, Volume 113, Issue 4, April 2026.
Abstract Let f$f$ be a holomorphic Hecke cusp form of weight k$k$ for SL2(Z)$\mathrm{SL}_2(\mathbb {Z})$, and let (λf(n))n⩾1$(\lambda _f(n))_{n\geqslant 1}$ denote its sequence of normalised Hecke eigenvalues. We compute the first and second moments of the sums S(x,f)=∑x⩽n⩽2xλf(n)$\mathcal {S}(x,f)=\sum _{x\leqslant n\leqslant 2x} \lambda _f(n)$, on ...

Non‐vanishing of Poincaré series on average

Mathematika, Volume 72, Issue 2, April 2026.
Abstract We study when Poincaré series for congruence subgroups do not vanish identically. We show that almost all Poincaré series with suitable parameters do not vanish when either the weight k$k$ or the index m$m$ varies in a dyadic interval. Crucially, analyzing the problem ‘on average’ over these weights or indices allows us to prove non‐vanishing ...

Internal Lee Waves Control Deep Ocean Turbulent Mixing in the Antarctic Circumpolar Current at 50°E

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Full‐depth (Surface‐to‐bottom) turbulent kinetic energy dissipation (TKED) observed with fast‐response thermistors across the Antarctic Circumpolar Current (ACC) at 50° $\mathit{{}^{\circ}}$E is compared with the energy flux of bottom‐generated internal waves estimated with high‐resolution multibeam bathymetry.

Harvesting the Spin–Orbit Interaction of Light to Generate Helicity‐Dependent Complex Rotational Motion in Optically Trapped Mesoscopic Matter

Nanophotonics, Volume 15, Issue 5, 16 March 2026.
Spin–orbit interaction (SOI) of light is exploited to generate helicity‐dependent complex rotational and revolution dynamics in optical tweezers. At the trap center, particle rotation is governed by the direct helicity that follows the input polarization.

Overproduction of 42 Amino Acids Long Amyloid Beta Leads to Activation of Secretory Autophagy and Development of Drusen‐Like Structures Originating From Retinal Pigment Epithelium

The FASEB Journal, Volume 40, Issue 5, 15 March 2026.
The role of 42 amino acids long amyloid beta (Aβ) in the retinal pigment epithelium (RPE) was investigated using 5xFAD mice model overproducing Aβ. The RPE cells of 5xFAD mice showed increased oxidative stress, accumulation of autophagy‐destined proteins, increased expression of secretory autophagy markers, and increase in epithelial‐to‐mesenchymal ...
