Evidence of an Extended Alfvén Wing System at Enceladus: Cassini's Multi‐Instrument Observations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract We report in situ evidence for Enceladus' Alfvén wing system and its coupling with Saturn's ionosphere, based on multi‐instrument observations from the Cassini spacecraft. Analysis of 36 events, including 13 from non‐flyby paths, confirms the existence of a Main Alfvén Wing (MAW) current system generated at Enceladus, and associated Reflected ...

East Asian VLBI Network Astrometry Toward the Star-forming Region G040.96+02.48 in the Extreme Outer Galaxy

The Astronomical Journal
Accurate astrometric measurements for star-forming regions located on the far side of the Milky Way remain scarce. In this work, we present the astrometric results for a 22 GHz water maser associated with star-forming region G040.96+02.48 located on the ...

Comparative multi‐omics in female mice reveals tissue‐specific vulnerabilities to chronic alcohol intake

Alcohol, Clinical and Experimental Research, Volume 50, Issue 2, February 2026.
Using mice, we applied multi‐omics to compare liver and skeletal muscle after chronic alcohol consumption. The liver responded more strongly across genes, proteins, and metabolites, with a lowered PC:PE ratio. Muscle showed inflammation, extracellular matrix activation, impaired mitochondrial energetics, and an elevated PC:PE ratio. Lipidomics affected

Large-scale Effect of an Accretion Burst in the High-Mass Young Stellar Object G358.93-0.03-MM1

The Astronomical Journal
The high-mass young stellar object G358.93-0.03-MM1 underwent a rapid accretion burst event from 2019 January to June, resulting in flares observed in most class II methanol maser transitions starting in mid-January.

Decaying Spruce Wood as a Factor in Soil Carbon and Energy Flow Through Microbial Communities

Environmental Microbiology Reports, Volume 17, Issue 6, December 2025.
Decomposing spruce deadwood enhances microbial activity, increases carbon and nitrogen availability and improves soil moisture retention. It plays a crucial role in long‐term carbon storage and biodiversity maintenance, influencing energy and nutrient cycling within forest ecosystems.

SiO v = 1 J = 5 → 4 Maser Emission from the Root of the “Water Fountain” Source W 43A

The Astrophysical Journal
We report here the first mapping of SiO v = 1 J  = 5 → 4 maser emission toward the “water fountain” source W 43A in order to explore the central stellar system driving the collimated, bipolar, fast jet.

The Discovery of Polarized Water Vapor Megamaser Emission in a Molecular Accretion Disk

The Astrophysical Journal Letters
For the first time in an extragalactic source, we detect linearly polarized H _2 O maser emission associated with the molecular accretion disk of NGC 1068.

Protostellar Outflows at the EarliesT Stages (POETS)

Astronomy & Astrophysics
Context. Magnetohydrodynamic (MHD) disk winds (DWs) can be responsible for removing angular momentum from the accretion disks of protostars, for driving mass accretion and disk evolution and dispersal, and, ultimately, for setting the conditions for ...

On Water Masers in Circumstellar Shells

The Astrophysical Journal, 1998
Detection rates for 22 GHz water masers from O-rich circumstellar shells are always less than 100%. This can in part be understood by revisiting high angular-resolution observations of masers in OH 39.7 + 1.5 and red supergiants. The pattern of occurrence for water masers around the pulsation cycle of OH 39.7 + 1.5 suggests that a detectable maser only
