Can UV light induce movement in cage-free laying hens?

open access: yesJournal of Applied Poultry Research, 2023
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]

open access: yes, 2006
1. We examined the relative changes in light intensity that initiate night-time locomotor activity changes in nymphs of the mayfly, Stenonema modestum (Heptageniidae).

A simple way to overcome the recalcitrance of the water fern Ceratopteris thalictroides (L.) Brongn. to cryopreservation

open access: yesActa Societatis Botanicorum Poloniae, 2015
Ceratopteris thalictroides is a water fern very sensitive to both dehydration and low temperature. This study focuses on the cryopreservation of this species by encapsulation-dehydration technique, in particular on the effects of pre-culture step ...

An intracellular transporter mitigates the CO2‐induced decline in iron content in Arabidopsis shoots

open access: yesFEBS Letters, EarlyView.
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 ...

The effects of pulse cycloheximide treatments on the light-induced recovery of mitotic divisions in antheridial filaments of Chara vulgaris

open access: yesActa Societatis Botanicorum Poloniae, 2014
Within the proliferative period of spermatogenesis in Chara vulgaris, the progression throughout successive cell divisions in antheridial filaments is greatly influenced by changes in photoperiodic conditions.

Augury of Darkness: The Low-Mass Dark Z' Portal [PDF]

open access: yes, 2016
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

open access: yesRoyal Society Open Science, 2016
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

open access: yesFEBS Letters, EarlyView.
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

open access: yesCurrent Objectives of Postgraduate American Studies, 2015
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 ...
