Towards a Long-Term Catalogue of Sunspot-Group Positions and Rotation Velocities from Kanzelhöhe Observatory: Differential Rotation and Possible Torsional Oscillation Signatures During Solar Cycle 25

Universe
This study presents Solar Cycle (SC) 25 (2020–2025) results from the homogeneous Kanzelhöhe Solar Observatory (KSO) catalogue project and completes the analysis of SCs 19–25. Only SC18 remains to be processed before the catalogue is finalized.

Structural retinal changes and visual field loss across timing of damage in children with cerebral visual impairment

Acta Ophthalmologica, EarlyView.
Abstract Purpose To investigate structural changes in the retina and optic nerve head (ONH) of children with cerebral visual impairment (CVI) across different timing of damage (TOD), and to relate these structural changes to visual field (VF) loss severity and pattern.

Superstrong Magnetic Fields in Sunspot Bipolar Light Bridges

The Astrophysical Journal Letters
Recent solar observations of bipolar light bridges (BLBs) in sunspots have, in a few individual cases, revealed magnetic fields up to 8.2 kG, which is at least twice as strong as typical values measured in sunspot umbrae.

A novel myopathy with autophagic vacuoles associated with biallelic variants in CLN8

Brain Pathology, EarlyView.
We describe a novel adult‐onset myopathy with autophagic vacuoles and characteristic features of ceroid lipofuscinosis associated with biallelic CLN8 variants, seizures, and muscle weakness. Autophagosomal/lysosomal deposition of curvilinear, autofluorescent material containing the mitochondrial adenosine triphosphate (ATP) synthase membrane subunit c ...

Differential Rotation of Individual Sunspots and Pores

The Astrophysical Journal
The analysis of the rotation rate of individual sunspots and pores was performed according to the data from the processing of observations by the Solar Dynamics Observatory/Helioseismic and Magnetic Imager in the period 2010–2024.

Renal‐vascular axis: unmasking its role in vascular endothelial growth factor‐inhibitor vascular toxicity in cancer patients

British Journal of Pharmacology, EarlyView.
Abstract Vascular toxicity is a growing concern in cancer patients receiving vascular endothelial growth factor inhibitor (VEGFi) therapy, posing a significant threat to patient prognosis. While the primary mechanism of VEGFi‐induced vascular toxicity is linked to redox‐sensitive reactions that disrupt vascular tone, leading to hypertension and ...

Can a Major Geomagnetic and Auroral Disturbance Originate From a Solar Active Region Close to the Limb?

Space Weather
When forecasting major geomagnetic storms, it is commonly assumed that coronal eruptions near the solar limb are not of concern. We here discuss two sequences of events: the Fátima storms of January 1938 and the Halloween storms of October/November 2003.

Kcnv2 E151X Mouse Captures Hallmarks of KCNV2‐Associated Retinal Dystrophy

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background KCNV2‐associated retinopathy is a rare inherited retinal dystrophy caused by variants in the KCNV2 gene, leading to disrupted photoreceptor behaviour and progressive deterioration of vision. Patients have characteristic electroretinography abnormalities, including reduced cone response, delayed and reduced rod response to low light ...
