A search for water masers toward extrasolar planets

open access: yes, 2006
Context: Water is the most common triatomic molecule in the universe and the basis of life on Earth. Astrophysical masers have been widely studied in recent years and have been shown to be invaluable probes of the details of the environment in which ...

A review of the historic and present ecological role of aquatic and shoreline wood, from forest to deep sea

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1091-1119, June 2026.
ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

Water and silicon-monoxide masers monitored towards the water fountain sources

open access: yes, 2021
We have investigated the evolution of 12 water fountain sources in real time in the accompanying H2O 2o and SiO masers through our FLASHING (Finest Legacy Acquisitions of SiO-/ H2O 2o-maser Ignitions by Nobeyama Generation) project. It has been confirmed

Phosphate starvation induces root cell‐type‐specific transcriptional responses and alternative splicing

open access: yesNew Phytologist, Volume 250, Issue 5, Page 3212-3229, June 2026.
Summary Phosphate (Pi) is an essential nutrient for plant growth, and understanding how Arabidopsis thaliana root cells respond to Pi deficiency is crucial to decipher whole plant responses. We perform high‐resolution transcriptomic profiling across five distinct root cell types, identifying differentially expressed genes (DEGs) and differential ...

An Updated Model for the Perseus Spiral Arm from Trigonometric Parallax and 3D Kinematic Distances of Distant Massive Stars

open access: yesThe Astrophysical Journal
We report trigonometric parallaxes and proper motions for three water masers and one methanol maser obtained with the Very Long Baseline Array as part of the Bar and Spiral Structure Legacy Survey.

A new water maser source in LBN594 [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1991
The detection of a new water maser source on the 6 16 → 5 23 transition in the Bok globule LBN 594 is presented. Besides the main feature, a number of velocity components were detected. Spectra taken within a few days interval suggest possible maser variability. Maser emission was also confirmed for two Ae/Be Herbig stars. Upper limits (3σ) are given

How Large, Decayed, and Moist Must Rotting Logs Be to Act as Thermally Buffered Microhabitats in Temperate Eastern United States Forests?

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
This study addresses the ecological role of coarse woody debris (CWD) as a thermally buffered microhabitat for saproxylic organisms in temperate eastern US forests. We measured internal and external log temperatures across four seasons in Southern Appalachian forests to test how log diameter, decay stage, and moisture influence thermal buffering.

Unveiling Ionized Jet Morphologies: Subarcsecond VLA Observations of Compact Radio Sources

open access: yesThe Astronomical Journal
We present subarcsecond ( θ ∼ 0 $\mathop{.}\limits^{\unicode{x02033}}$ 1) resolution VLA 1.3 cm continuum and 22.2 GHz H _2 O maser observations toward 15 compact radio continuum sources with rising spectral index and eight string-like radio continuum ...

A Natural Language Processing Approach to Identifying Partisan Framing of Climate Change Denialism, Fatalism, and Solutions in US Congressional Speeches

open access: yesPolicy Studies Journal, Volume 54, Issue 2, May 2026.
ABSTRACT This study examines the evolution of climate change discourse in the United States Congress from 1987 to 2017, employing natural language processing (NLP) techniques to analyze floor speeches. Using a la carte (ALC) word embeddings, we investigate how Democratic and Republican members of Congress frame climate change, focusing on denialist ...

Submillimetre water masers at 437, 439, 471, and 474 GHz towards evolved stars

open access: yes, 2020
Aims. Here we aim to characterise submillimetre water masers at 437, 439, 471, and 474 GHz towards a sample of evolved stars. Methods. We used the Atacama Pathfinder Experiment (APEX1) to observe submillimetre water transitions and the CO (4–3) line ...
