Artificial Light Increases Local Predator Abundance, Predation Rates, and Herbivory. [PDF]

open access: yes, 2019
Human activity is rapidly increasing the radiance and geographic extent of artificial light at night (ALAN) leading to alterations in the development, behavior, and physiological state of many organisms.

Using novel methodologies to examine the impact of artificial light at night on the cortisol stress response in dispersing Atlantic salmon (Salmo salarL.) fry [PDF]

open access: yes, 2015
Artificial light at night (ALAN) is gaining recognition as having an important anthropogenic impact on the environment, yet the behavioural and physiological impacts of this stressor are largely unknown.

Paternal Caffeine Exposure Programs Offspring Stress Vulnerability via Sperm Dlk1‐Dio3 Imprinting‐Directed Remodeling of a Novel Neural Circuit

open access: yesAdvanced Science, EarlyView.
The study elucidates that paternal preconception stress can drive offspring hyperresponsivity of the stress system via hypomethylation of a specific DNA region in sperm. This key link is confirmed in a cohort of prospective fathers: the epigenetic alteration is associated with elevated stress hormone levels.

La pollution lumineuse : passer de la définition d'un problème à sa prise en compte technique [PDF]

open access: yes, 2009
International audienceAt night-time, artificial light is an essential requirement for certain functions and yet it has an adverse effect on the night, on darkness, or on what is commonly accepted as a shared natural resource.

Potential biological and ecological effects of flickering artificial light. [PDF]

open access: yes, 2016
Organisms have evolved under stable natural lighting regimes, employing cues from these to govern key ecological processes. However, the extent and density of artificial lighting within the environment has increased recently, causing widespread ...

Inhibitory Decay and Supercritical Brain Dynamics During Sleep Deprivation

open access: yesAdvanced Science, EarlyView.
Sleep deprivation progressively shifts human brain dynamics from near‐critical toward supercritical states, as revealed by neuronal avalanche analysis of resting‐state fMRI. These changes track subjective sleep pressure rather than vigilance lapses and show marked network heterogeneity. A circuit model suggests that reduced inhibitory efficacy provides

Confessions of a Poverty Researcher: My Journey Through the Foothills of Scholarship

open access: yesAustralian Journal of Social Issues, EarlyView.
ABSTRACT This paper describes the key events, experiences and ideas that influenced the author's career as a poverty researcher. He describes how his early disillusion with economics was replaced by a spark of interest in social issues and how his migration from the UK to Australia in the mid‐1970s provided the impetus to begin what became a lifetime ...

Artificial light at night inhibits mating in a Geometrid moth

open access: yesInsect Conservation and Diversity, 2015
Abstract Levels of artificial night lighting are increasing rapidly worldwide, subjecting nocturnal organisms to a major change in their environment. Many moth species are strongly attracted to sources of artificial night lighting, with potentially severe, yet poorly

The HCMV‐encoded miR‐UL36‐3p promotes angiogenesis of endothelial cells by downregulating FOXO3

open access: yesAnimal Models and Experimental Medicine, EarlyView.
This illustration shows the role of hcmv‐miR‐UL36‐3p in endothelial cell angiogenesis. During productive infection, endothelial cells express HCMV‐encoded miRNAs. Viral hcmv‐miR‐UL36‐3p promotes endothelial cell proliferation, migration, and capillary tube formation by directly targeting and downregulating FOXO3. The pro‐angiogenic activity of hcmv‐miR‐

An Urban Migraine: The Influence of Artificial Light at Night on Aquatic Primary Productivity [PDF]

open access: yes, 2016
Artificial light at night (ALAN), or unnatural lighting produced by anthropogenic sources, has drastically altered the nighttime environment and is anticipated to increase as urban populations grow and electricity expands into previously unlit areas. The
