Specimen‐tailored ‘lived’ climate reveals precipitation onset and amount best predict specimen phenology, but only weakly predict estimated reproduction across a clade

New Phytologist, EarlyView.
Summary Herbarium specimens are widely distributed in space and time, thereby capturing diverse conditions. We reconstructed specimen ‘lived’ climate from knowledge of germination cues and collection dates for 14 annual species in the Streptanthus (s.l.) clade (Brassicaceae) to ask: which climate attributes best explain specimen phenological stage and ...

Weak Nuclear Divergence Despite Pronounced Mitochondrial Divergence Within a Widespread Desert‐Inhabiting Palearctic Lark (Aves: Alaudidae)

Zoologica Scripta, EarlyView.
ABSTRACT The Bar‐tailed Lark Ammomanes cinctura is a polytypic bird species with a wide distribution. One of its three subspecies, A. c. arenicolor, has previously been found to show deep mitochondrial divergence between its geographically most distant populations, from Morocco and Saudi Arabia, respectively.

Versatile and Highly Efficient MRI Simulation of Arbitrary Motion in KomaMRI

Magnetic Resonance in Medicine, Volume 95, Issue 3, Page 1791-1803, March 2026.
ABSTRACT Purpose To extend the KomaMRI simulator with motion capabilities that enable the simulation of both simple, parametrizable motion patterns and arbitrarily complex spin trajectories. Additionally, we introduce a novel file format for storing and sharing dynamic digital phantoms.

Assessment of Vehicle Stability Processes Under Unsteady Flow Conditions

Journal of Flood Risk Management, Volume 19, Issue 1, March 2026.
ABSTRACT The vehicle stability criteria are based on experimental and theoretical studies that do not account for the unsteady nature of floods. The rapid variation of depths and velocities in floods causes an additional hydrodynamic force in the direction of the flow, destabilising a vehicle that would otherwise be safe in steady flow conditions.

Alternative Pathway for Methyl Supply through the Coupling of SHMT1 and PEMT to Maintain Astrocytic Homeostasis in Parkinson's Disease

Advanced Science, Volume 13, Issue 7, 3 February 2026.
In Parkinson's disease, SHMT1 downregulation disrupts its interaction with PEMT in astrocytes, reducing SAM levels. This leads to H3K4me1 hypomethylation and decreased Slc1a2/Glul expression, ultimately exacerbating neuroexcitotoxicity and dopaminergic neuron loss.

Scanner‐based real‐time automated volumetry reporting of the fetus, amniotic fluid, placenta, and umbilical cord for fetal MRI at 0.55T

Magnetic Resonance in Medicine, Volume 95, Issue 2, Page 975-986, February 2026.
Abstract Purpose This work aims to enable real‐time automated intra‐uterine volumetric reporting and fetal weight estimation for fetal MRI, deployed directly on the scanner. Methods A multi‐region segmentation nnUNet was trained on 146 images of 73 fetal subjects (coronal and axial orientations) for the parcellation of the fetal head, fetal body ...

Cartesian MaxGIRF: Model‐based EPI reconstruction incorporating gradient nonlinearity and concomitant field effects

Magnetic Resonance in Medicine, Volume 95, Issue 2, Page 1044-1067, February 2026.
Abstract Purpose Lower field strength scanners with large bore size or complex geometries, and scanners with stronger gradient systems experience increased gradient nonlinearity and concomitant fields, each of which causes distortions in EPI. Current correction approaches based on image‐domain interpolation introduce undesirable spatial blurring.

Molecular phylogeny and morphological characterization revealed Candolleomyces mianwaliensis Psathyrellaceae, Agaricales, a new species from Punjab, Pakistan

Nordic Journal of Botany, Volume 2026, Issue 2, February 2026.
Candolleomyces mianwaliensis is described as a new species from Mianwali District, Punjab Pakistan. The species is characterized by spherical to plane pileus bearing pale orange irregular scales scattered over smooth dark orange surface when young, turning into off‐white scales over brown to dark brown surface towards maturity, and a double membranous ...
