Proper Motion of Water Masers Associated with IRAS 21391+5802: Bipolar Outflow and an AU-Scale Dusty Circumstellar Shell [PDF]

, 2000
We present VLBA observations of water maser emission associated with the star-forming region IRAS 21391+5802, which is embedded in a bright rimmed cometary globule in IC1396. The angular resolution of the maps is about 0.8 mas, corresponding to a spatial

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

Radio Continuum and Water Maser Observations of the High-mass Protostar IRAS 19035+0641 A

The Astrophysical Journal
We present Very Large Array 1.3 cm continuum and 22.2 GHz H _2 O maser observations of the high-mass protostellar object IRAS 19035+0641 A. Our observations unveil an elongated bipolar 1.3 cm continuum structure at scales ≲500 au, which, together with a ...

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.

An Outflow-driven Water Maser Associated with Positive Black Hole Feedback in the Dwarf Galaxy Henize 2–10

The Astrophysical Journal
Henize 2–10 is a dwarf galaxy experiencing positive black hole (BH) feedback from a radio-detected low-luminosity active galactic nucleus. Previous Green Bank Telescope (GBT) observations detected a H _2 O “kilomaser” in Henize 2–10, but the low angular ...

A VLA Search for Water Masers in Six HII Regions: Tracers of Triggered Low-Mass Star Formation

, 2004
We present a search for water maser emission at 22 GHz associated with young low-mass protostars in six HII regions -- M16, M20, NGC 2264, NGC 6357, S125, and S140. The survey was conducted with the NRAO Very Large Array from 2000 to 2002. For several of

Scientific Opinion on the application of physiologically based kinetic (PBK) modelling for the quantitative in vitro to in vivo extrapolation (QIVIVE) of developmental neurotoxicity in vitro battery (DNT IVB) data for pesticide active substances

EFSA Journal, Volume 23, Issue 12, December 2025.
Abstract EFSA requested the Panel on Plant Protection Products and their Residues (PPR Panel) to produce a Scientific Opinion on the application of physiologically based kinetic (PBK) modelling for the quantitative in vitro to in vivo extrapolation (QIVIVE) of data from the 17‐assay developmental neurotoxicity in vitro battery (DNT IVB) for pesticide ...

On the Structure of the Sagittarius Spiral Arm in the Inner Milky Way

The Astronomical Journal
We report measurements of trigonometric parallax and proper motion for two 6.7 GHz methanol and two 22 GHz water masers located in the far portion of the Sagittarius spiral arm as part of the BeSSeL Survey.

RadioAstron space-VLBI project: studies of masers in star forming regions of our Galaxy and megamasers in external galaxies [PDF]

, 2017
Observations of the masers in the course of RadioAstron mission yielded detections of fringes for a number of sources in both water and hydroxyl maser transitions. Several sources display numerous ultra-compact details. This proves that implementation of

Lithium in plants

New Phytologist, Volume 248, Issue 4, Page 1639-1654, November 2025.
Summary The physiological significance of lithium (Li+) remains largely unexplored in plants despite its consistent presence in at least trace concentrations in plant tissues. While Li+ has traditionally been associated with salinity‐like stress symptoms and presumed to utilise sodium (Na+) transport pathways, accumulating evidence points to multiple ...
