Humanities, 2021 This article argues that darkness contributes to the creation of, and expands the concept of, heterotopias. In Sarah Waters’s neo-Victorian trilogy, consisting of Tipping the Velvet (1998), Affinity (1999), and Fingersmith (2002), her characters utilize ...

Mapping the evolution of mitochondrial complex I through structural variation
FEBS Letters, EarlyView.Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Seeing Through the End Time: From Lord Byron’s “Darkness” to The Dark Mountain Project
Current 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 ...

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes
FEBS Letters, EarlyView.The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Anthropogenic disruption of the night sky darkness in urban and rural areas
Royal 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

Dark energy: Staring into darkness [PDF]
Nature, 2016 The path to understanding dark energy begins with a single question: has it always been the same throughout the history of the Universe?

The role and implications of mammalian cellular circadian entrainment
FEBS Letters, EarlyView.At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

Molecular bases of circadian magnesium rhythms across eukaryotes
FEBS Letters, EarlyView.Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

DARK ENERGY, DARK MATTER AND GRAVITY [PDF]
International Journal of Modern Physics D, 2007 We discuss the motivation for high accuracy relativistic gravitational experiments in the solar system and complementary cosmological tests. We focus our attention on the issue of distinguishing a generic scalar theory of gravity as the underlying physical theory from the usual general-relativistic picture, where one expects the presence of ...
