Validating COI eDNA Metabarcoding Primers for Detection of Subterranean Fauna

open access: yesMolecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT Subterranean ecosystems host a diverse range of ancient fauna, but studying these ecosystems is challenging due to significant sampling difficulties. Environmental DNA (eDNA) metabarcoding offers a promising approach for monitoring subterranean biodiversity, yet issues such as primer bias and non‐target amplification can complicate its ...

Differential Gene Expression in Human Hippocampus With Aging

open access: yesAging Cell, Volume 25, Issue 4, April 2026.
2 complementary analysis from a transcriptome study in human hippocampal samples of different ages revealed a set of genes differentially expressed in aged individuals linked to inflammation and immune system pathways, DNA repair (RAD23) or neural activity.

Fight song: variation in singing behaviour and song structure during natural agonistic interactions in a tropical songbird, Adelaide's Warbler (Setophaga adelaidae)

open access: yesIbis, Volume 168, Issue 2, Page 766-778, April 2026.
Birds may use their singing behaviours and song structure as agonistic signals in territorial encounters. We conducted an observational study to test this hypothesis in male Adelaide's Warblers Setophaga adelaidae, a tropical songbird that defends a territory year‐round.

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

open access: yesIbis, 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 ...

Mechanical and Dielectric Properties of Porous Slip Cast Silicon Nitride: Yttrium Oxide‐Aluminum Oxide Sintering Aids

open access: yesInternational Journal of Applied Ceramic Technology, Volume 23, Issue 2, April 2026.
Silicon nitride samples were slip cast using yttrium oxide‐aluminum sintering aids to fabricate porous materials for radar frequency windows. Microstructure and phase composition were determined. Flexural strength, elastic modulus, dielectric constant, and loss tangent were collected from room temperature to elevated temperatures up to 1200°C.

Snow‐Covered Insights From Above and Below: High‐Frequency Measurement of Nitrogen Dioxide From Space and Ground

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The Tropospheric Emissions: Monitoring of Pollution (TEMPO) satellite provides hourly air quality measurements over North America. This study evaluates TEMPO NO2 ${\text{NO}}_{2}$ observations over snow‐covered surfaces, highlighting its ability to capture sharp spatial and temporal gradients in NO2 ${\text{NO}}_{2}$ vertical column densities ...
