The Value of Darkness: A Moral Framework for Urban Nighttime Lighting

open access: yesScience and Engineering Ethics, 2017
The adverse effects of artificial nighttime lighting, known as light pollution, are emerging as an important environmental issue. To address these effects, current scientific research focuses mainly on identifying what is bad or undesirable about certain

The Eye Pupil’s Response to Static and Dynamic Illusions of Luminosity and Darkness

open access: yesi-Perception, 2017
Pupil diameters were recorded with an eye-tracker while participants observed cruciform patterns of gray-scale gradients that evoked illusions of enhanced brightness (glare) or of enhanced darkness. The illusions were either presented as static images or

Dark catalysis [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2017
Recently it was shown that dark matter with mass of order the weak scale can be charged under a new long-range force, decoupled from the Standard Model, with only weak constraints from early Universe cosmology. Here we consider the implications of an additional charged particle $C$ that is light enough to lead to significant dissipative dynamics on ...

Actin filament reorganisation controlled by the SCAR/WAVE complex mediates stomatal response to darkness

open access: yesNew Phytologist, 2017
Summary Stomata respond to darkness by closing to prevent excessive water loss during the night. Although the reorganisation of actin filaments during stomatal closure is documented, the underlying mechanisms responsible for dark‐induced cytoskeletal ...

A Short Period of Darkness after Mixing of Growing Pigs Intended for PDO Hams Production Reduces Skin Lesions

open access: yesAnimals, 2020
Agonistic behavior after the regrouping of unfamiliar pigs has been recognized as one of the major welfare issues for pig husbandry, as it may result in lesions, lameness, and health problems. One scarcely investigated strategy to curb agonistic behavior

Influence of Lighting and Laser Irradiation on the Germination of Caper Seeds

open access: yesAgriculture, 2022
Caper seeds present difficulties in their germination, which has been studied by several research teams. It is known that light can release dormancy in some seeds, but its effect on caper seed germination has not yet been deeply studied.

Gaming the heart of darkness [PDF]

open access: yes, 2018
The history of Joseph Conrad’s Heart of Darkness has been one of adaptation and change. The enduring story is based upon Conrad’s experiences in the Congo in the 1890s and has been published as a novella in 1902.

DARK MATTER, AND ITS DARKNESS [PDF]

open access: yesInternational Journal of Modern Physics D, 2006
Assuming the validity of the general relativistic description of gravitation on astrophysical and cosmological length scales, we analytically infer that the Friedmann–Robertson–Walker cosmology with Einsteinian cosmological constant, and a vanishing spatial curvature constant, unambiguously requires a significant amount of dark matter.
