Terrestrial Analogs to Titan for Geophysical Research

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

Environmental Quenching of Low-surface-brightness Galaxies Near Hosts from Large Magellanic Cloud to Milky Way Mass Scales

The Astrophysical Journal
Low-surface-brightness galaxies (LSBGs) are excellent probes of quenching and other environmental processes near massive galaxies. We study an extensive sample of LSBGs near massive hosts in the local universe that are distributed across a diverse range ...

A Smartphone and Web‐Based Automated Platform for Segmenting Urinary Tract Infection Using a Deep Learning‐Based Approach

Engineering Reports, Volume 8, Issue 4, April 2026.
This study presents a deep learning–powered urinary sediment analysis system designed to operate on both web and mobile platforms. At its core is a UNet++ multi‐class segmentation model trained to identify various sediment types, including background, rod, red blood cells, white blood cells, yeast, miscellaneous, single epithelial cell, small ...

Imported Retail Beef and Chicken Meat Products Serve as Reservoirs for Emerging Antibiotic‐Resistant Pathotypes of Escherichia coli in Pristine Areas Free From Agricultural Activity

MicrobiologyOpen, Volume 15, Issue 2, April 2026.
Retail meat–derived E. coli frequently harbored multidrug‑resistance phenotypes, diverse virulence determinants, and plasmid‑encoded resistance genes with high conjugative potential. Results indicate meat and poultry as underrecognized reservoirs facilitating dissemination of antimicrobial resistance and pathogenic lineages, with imported products ...

Massive low surface brightness galaxies [PDF]

A multi-wavelength study of an extreme type of galaxy which will assist us in our attempts to understand the formation and evolution of galaxies was completed. In particular, a subset of low surface brightness (bar-mu(sub B) is approximately greater than

Cowbirds use conspecific social information to detect host nests in the wild

Ibis, Volume 168, Issue 2, Page 799-804, April 2026.
Recent work shows that hosts of avian brood parasites use social information to increase egg rejection rates, but fewer studies explore how parasites themselves use such information to detect host nests in the wild. To determine whether wild Brown‐headed Cowbirds Molothrus ater use social information to detect host nests, we measured how individual ...

The Contribution of Low Surface Brightness Galaxies to Faint Galaxy Counts

The Astrophysical Journal, 1995
Low Surface-Brightness (LSB) galaxies are severely underrepresented in surveys used to define the local luminosity function (LF), but could it in principle be detected in deep surveys. To explore the possible contribution of such objects to faint galaxy counts, we construct catalogs of simulated non-evolving galaxies drawn from a multivariate ...
