Can UV light induce movement in cage-free laying hens?
SUMMARY: In recent years, more farms have been transitioning to cage-free systems as multiple states passed regulations banning use of conventional cages, and several large food service companies pledged to exclusively source cage-free eggs by 2025–2026.

Clouds, shadows, or twilight? Mayfly nymphs recognise the difference [PDF]
1. We examined the relative changes in light intensity that initiate night-time locomotor activity changes in nymphs of the mayfly, Stenonema modestum (Heptageniidae).

An intracellular transporter mitigates the CO2‐induced decline in iron content in Arabidopsis shoots
This study identifies a gene encoding a transmembrane protein, MIC, which contributes to the reduction of shoot Fe content observed in plants under elevated CO2. MIC is a putative Fe transporter localized to the Golgi and endosomal compartments. Its post‐translational regulation in roots may represent a potential target for improving plant nutrition ...

Augury of Darkness: The Low-Mass Dark Z' Portal [PDF]
Dirac fermion dark matter models with heavy $Z^{\prime}$ mediators are subject to stringent constraints from spin-independent direct searches and from LHC bounds, cornering them to live near the $Z^{\prime}$ resonance.

Anthropogenic disruption of the night sky darkness in urban and rural areas
The growing emissions of artificial light to the atmosphere are producing, among other effects, a significant increase of the night sky brightness (NSB) above its expected natural values. A permanent sensor network has been deployed in Galicia (northwest

A Cre‐dependent lentiviral vector for neuron subtype‐specific expression of large proteins
We designed a versatile and modular lentivector comprising a Cre‐dependent switch and self‐cleaving 2A peptide and tested it for co‐expression of GFP and a 2.8 kb gene of interest (GOI) in mouse cortical parvalbumin (PV+) interneurons and midbrain dopamine (TH+) neurons.

Seeing Through the End Time: From Lord Byron’s “Darkness” to The Dark Mountain Project
This essay contends with the dark side of environmental literature by examining Lord Byron’s apocalyptic poem “Darkness“ (1816) ecocritically, drawing on Timothy Morton’s concepts of dark ecology “and ecological thought“ to ask how darkness functions in ...
