Increasing artificial light at night enhances salmonid predator foraging efficiency in an urbanized lake

Limnology and Oceanography, Volume 71, Issue 8, August 2026.
Abstract Artificial light at night (ALAN) poses a threat to ecosystems globally. It includes both direct and indirect light, or skyglow, which occurs when ALAN scatters in the atmosphere, extending beyond its original source. We analyzed ALAN trends in Lake Washington, WA, from 2014 to 2023 using Visible Infrared Imaging Radiometer Suite (VIIRS ...

Pulling Back the Curtain on Shocks and Star Formation in NGC 1266 with Gemini-NIFS

The Astrophysical Journal
We present Gemini near-infrared integral field spectrograph K -band observations of the central 400 pc of NGC 1266, a nearby ( D ≈ 30 Mpc) post-starburst galaxy with a powerful multiphase outflow and a shocked interstellar medium.

An Ultrafast Time Resolved Infrared and Computational Study of the Photochemistry of Ethyl 2‐Diazo‐3,3,3‐Trifluoropropanoate (CF3CN2CO2Et)

Journal of Physical Organic Chemistry, Volume 39, Issue 8, August 2026.
The photochemistry of ethyl 2‐diazo‐3,3,3‐trifluoropropanoate shows that its excited singlet state undergoes internal conversion, carbene formation, and diazirine formation. The resulting singlet carbene reacts through solvent‐dependent pathways, forming ylides in methanol and acetonitrile or a C–Cl insertion product in chloroform.

Infrared Colors of Small Serendipitously Found Asteroids in the UKIRT Hemisphere Survey

The Astronomical Journal
The UKIRT Hemisphere Survey covers the northern sky in the infrared from 0° to 60° decl. Current data releases include both J and K bands, with H -band data forthcoming. Here, we present a novel pipeline to recover asteroids from this survey data.

Widespread Increase in Global Plant Water Stress Obscured by Greening

AGU Advances, Volume 7, Issue 4, August 2026.
Abstract Understanding the vulnerability of plants to more severe and frequent drought events and developing adaptive management strategies requires robust methods for quantifying long‐term changes in plant water stress (PWS). Most data‐driven explorations of long‐term trends in PWS have focused on alterations in canopy structure (e.g., leaf area index)

Lyα Profile Shape as an Escape-fraction Diagnostic at High Redshift

The Astrophysical Journal
While the shape of the Ly α profile is viewed as one of the best tracers of ionizing-photon escape fraction ( f _esc ) within low-redshift ( z ∼ 0.3) surveys of the Lyman continuum, this connection remains untested at high redshift. Here, we combine deep,

Features in the Visible Spectra of the Enceladus Particle Plume and E Ring: Potential Evidence of Organic Materials and/or Missing Sub‐Micron Particles

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract Visible spectra of the Enceladus particle plume and E ring contain evidence for a change in spectral slope around 0.5 μm. This feature can be seen in data obtained by both the Visual and Infrared Mapping Spectrometer and Imaging Science Subsystem onboard the Cassini Spacecraft, and is consistent with the slope change seen in the surface ...

Atmospheric Constituent Data Assimilation in NASA's Goddard Earth Observing System

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Many of today's most significant and urgent scientific questions, including those about the impact of human activity on air quality and radiative forcing, require the synthesis of observations of atmospheric constituents and scientific theory.

Jovian Auroral Proton Precipitation

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract The total power of the Jovian aurora is about 1013–1014 W with ultraviolet emission observed in the Lyman and Werner bands of molecular hydrogen. X‐ray, radio, and infrared emissions have also been observed. The Jovian Auroral Distributions Experiment and the Jovian Energetic Particle Detector Instrument onboard the Juno spacecraft, orbiting ...
