The flares associated with the abnormal rotation rates of the bipolar sunspots: Reconnection probably below the surface

, 2003
We use the observations of Kodaikanal observatory white light pictures to study the association between the rotation rates of the bipolar sunspots and triggering of the flares.

Vitreoretinal complications and surgical outcomes in patients with X‐linked retinoschisis

Acta Ophthalmologica, Volume 104, Issue 4, Page 410-422, June 2026.
Abstract Purpose X‐linked retinoschisis (XLRS) is an inherited vitreoretinal disorder characterized by macular retinoschisis. In a subgroup of patients, peripheral retinoschisis can occur, potentially leading to complications such as vitreous haemorrhage (VH) and retinal detachment (RD).

Advancing Brain and Body Vascular Imaging in Bipolar Disorder: A Report From the International Society for Bipolar Disorders Vascular Task Force

Bipolar Disorders, Volume 28, Issue 4, June 2026.
ABSTRACT Objectives The heart–brain nexus is increasingly recognized as important for human health. Nonetheless, integration of this perspective in research and treatment remains limited in psychiatry, particularly in bipolar disorder (BD). Multisystem vascular imaging may help elucidate mechanisms linking heart and brain health in BD.

Human‐Interpretable SEP Event Prediction Using White‐Box Explainable AI

Space Weather, Volume 24, Issue 4, April 2026.
Abstract Solar energetic particle (SEP) events pose radiation risks to astronauts and space systems, making their prediction essential. Although various prediction models have been developed, most machine learning (ML)‐based models lack interpretability; that is, it is difficult to explain the reasons behind individual predictions.

Superposed Epoch Analysis of Extreme Geomagnetic Disturbances at Auroral Zone Latitudes Over a Solar Cycle

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract Intense and rapidly changing electrical currents in near‐Earth space produce geomagnetic disturbances (GMDs) with large magnetic field rates of change (dB/dt) and in turn large geomagnetically induced currents (GICs) in nearby power lines and pipelines. This study builds on the work of Engebretson, Yang, et al.

The Making of Delta Sunspots

The Astrophysical Journal
We explore what fraction of delta sunspots with a sharp polarity inversion line (PIL) in photospheric magnetograms are produced by a writhe kink in an emerging twisted flux rope.

Dual 1550‐nm Erbium Glass Fiber and 1927‐nm Thulium Fiber Non‐ablative Fractional Laser System Treatment in Patients With Skin of Color: A Review of Clinical Studies and Unmet Needs

Lasers in Surgery and Medicine, Volume 58, Issue 3, Page 169-179, March 2026.
ABSTRACT Objectives To review the efficacy and safety of the dual 1550‐nm erbium glass fiber and 1927‐nm thulium fiber non‐ablative fractional laser system in patients with skin of color (ie, Fitzpatrick skin types [FSTs] III–VI). Materials and Methods Efficacy, safety, and histologic outcomes were reviewed from 15 clinical studies examining the use of
