Dark metabolism: a molecular insight into how the Antarctic sea‐ice diatom Fragilariopsis cylindrus survives long‐term darkness

open access: yesNew Phytologist, 2019
Summary Light underneath Antarctic sea‐ice is below detectable limits for up to 4 months of the year. The ability of Antarctic sea‐ice diatoms to survive this prolonged darkness relies on their metabolic capability. This study is the first to examine the

Dark group: dark energy and dark matter [PDF]

open access: yesPhysics Letters B, 2004
We study the possibility that a dark group, a gauge group with particles interacting with the standard model particles only via gravity, is responsible for containing the dark energy and dark matter required by present day observations. We show that it is indeed possible and we determine the constrains for the dark group.

Effect of darkness on the early postlarval development of Haliotis corrugata abalone fed different diatom densities

open access: yesCiencias Marinas, 2009
Four-day-old postlarvae of the abalone Haliotis corrugata were exposed to different diatom densities (Navicula incerta, 0 to 8000 cells mm–2) under two illumination conditions: constant light (19–21 µmol quanta m–2 s–1) and darkness. The effect of these

Grasping darkness: the dark ecological network as a social-ecological framework to limit the impacts of light pollution on biodiversity

open access: yesEcology and Society, 2021
Artificial light at night (ALAN) is nowadays recognized as a major anthropogenic pressure on the environment on a global scale and as such is called light pollution.

Effects of light and darkness on pH regulation in three coral species exposed to seawater acidification

open access: yesScientific Reports, 2019
The resilience of corals to ocean acidification has been proposed to rely on regulation of extracellular calcifying medium pH (pHECM), but few studies have compared the capacity of coral species to control this parameter at elevated pCO2.

DARK ENERGY WITH DARK SPINORS [PDF]

open access: yesModern Physics Letters A, 2010
Ever since the first observations that we are living in an accelerating universe, it has been asked what dark energy is. There are various explanations, all of which have various drawbacks or inconsistencies. Here we show that using a dark spinor field it is possible to have an equation of state that crosses the phantom divide, becoming a dark phantom
