Photons from Neutrinos: The Gamma-Ray Echo of a Supernova Neutrino Burst

The Astrophysical Journal
When a star undergoes core collapse, a vast amount of energy is released in a ∼10 s long burst of neutrinos of all species. Inverse beta decay in the star’s hydrogen envelope causes an electromagnetic cascade that ultimately results in a flare of gamma ...

Description of the skull, braincase, and dentition of Moschognathus whaitsi (Dinocephalia, Tapinocephalia), and its palaeobiological and behavioral implications

The Anatomical Record, EarlyView.
Abstract A subadult Moschognathus whaitsi from the Eastern Cape Province, South Africa, was scanned using synchrotron radiation X‐ray computed tomography (SRXCT). Its subadult state allowed the cranial bones and teeth to be identified and individually reconstructed in 3D.

Flare Activity and Magnetic Feature Analysis of the Flare Stars. III. K-type Dwarf Binary Components

The Astrophysical Journal
We analyze the light curve of 199 dwarf stars that are members of binary systems resolved by Kepler mission. All of them are K-type active stars in binary systems of which their flare activity has been confirmed.

Loss of Tripartite Motif–Containing Protein 21 and UVB‐Induced Systemic Inflammation by Regulating DNA‐Sensing Pathways

Arthritis &Rheumatology, EarlyView.
Objective Patients with systemic lupus erythematosus (SLE) experience photosensitivity, with exposure to UVB light driving lupus flares and triggering symptoms like joint pain, fatigue, and cutaneous lesions. Although the mechanism(s) linking UVB exposure to systemic effects are unclear, type I interferons (IFNs) are known to play a role.

American College of Rheumatology Guidance Statement for Diagnosis and Management of VEXAS Developed by the International VEXAS Working Group Expert Panel

Arthritis &Rheumatology, EarlyView.
Objective Vacuoles E1 enzyme X‐linked autoinflammatory somatic syndrome (VEXAS) is a recently identified rare genetic disorder associated with somatic mutations in the UBA1 gene. VEXAS presents with a combination of inflammatory and hematologic manifestations, leading to increased morbidity and mortality.

Star−Disk Collisions: Implications for Quasi-periodic Eruptions and Other Transients near Supermassive Black Holes

The Astrophysical Journal
We use Athena++ to study the hydrodynamics of repeated star−accretion disk collisions close to supermassive black holes, and we discuss their implications for the origin of quasi-periodic eruptions (QPEs) and other repeating nuclear transients.

Differences in IgG Sialylation Distinguish Asymptomatic From Symptomatic Antinuclear Antibody–Positive Individuals

Arthritis &Rheumatology, EarlyView.
Objective The transition from asymptomatic antinuclear antibody (ANA) positivity to systemic autoimmune rheumatic disease (SARD) is associated with increased production of proinflammatory factors such as tumor necrosis factor α (TNFα). Here we investigate whether the relative absence of inflammation in asymptomatic ANA+ individuals (ANA+NS) results ...

Case‐Based Immunology: B Cells and Systemic Sclerosis Interstitial Lung Disease

Arthritis &Rheumatology, EarlyView.
Interstitial lung disease (ILD) is an important complication of systemic sclerosis (SSc), with high mortality and morbidity. Recent clinical studies in SSc‐ILD have led to US Food and Drug Administration–approved therapies in SSc‐ILD. Importantly, evidence from these studies has been extrapolated to guide management of ILDs of other systemic autoimmune

A Seven-day Multiwavelength Flare Campaign on AU Mic. III. Quiescent and Flaring Properties of the X-Ray Spectra and Chromospheric Lines

The Astrophysical Journal
We present the X-ray quiescent and flaring properties from a unique, 7 days multiwavelength observing campaign on the M1 flare star AU Mic. Combining the XMM-Newton X-ray spectra with the chromospheric line and broadband near-UV (NUV) and optical ...
