Title By the light of the silvery Moon: fact and fiction Type Journal Article
Year 2013 Publication Physics Education Abbreviated Journal Phys. Educ.
Volume 48 Issue 3 Pages 360-367
Keywords Vision; moonlight; Purkinje effect; Purkinje shift; mesopic
Abstract Is moonlight 'silver' or 'cold'? In this paper we discuss the interesting combination of factors that contribute to the common descriptions of moonlight. Sunlight is reflected from the lunar surface and red-shifted. When traversing the atmosphere, moonlight is further depleted of short wavelength content by Rayleigh scattering. We measured the spectra of the moonlight to show these effects and compared them with sunlight. All measurements, including spectral reflectance, suggest that moonlight is redder than sunlight. The silvery Moon is just an illusion due to the properties and behaviour of our own eyes, including the responses of rods and cones and the physiological perceptive phenomenon called Purkinje shift.

Title Exposure to dim light at night prior to conception attenuates offspring innate immune responses Type Journal Article
Year 2020 Publication PloS one Abbreviated Journal PLoS One
Volume 15 Issue 4 Pages e0231140
Keywords Animals
Abstract Functional circadian timekeeping is necessary for homeostatic control of the immune system and appropriate immune responsiveness. Disruption of natural light-dark cycles, through light at night (LAN), impairs innate and adaptive immune responses in nocturnal rodents. These altered immune responses are associated with disrupted endogenous gene transcriptional and endocrine cycles. However, few studies have addressed the multigenerational consequences of systemic circadian rhythm disruption. We hypothesized that parental exposure to dim LAN (dLAN) would alter innate immune and sickness responses to an endotoxin challenge in adult offspring gestated and reared in dark nights. Adult male and female Siberian hamsters were exposed to either dark nights (DARK) or dLAN (~5 lux) for 8 weeks, then paired, mated, and thereafter housed under dark nights. Maternal exposure to dLAN prior to conception impaired febrile responses and increased splenic il-1 production in response to LPS in male offspring. Paternal pre-conception dLAN dampened offspring tnf-alpha expression in the hypothalamus, reduced serum bactericidal capacity, and dark phase locomotor activity. These changes occurred despite offspring being conceived, gestated, and reared under standard dark night conditions. Overall, these data suggest that dLAN has intergenerational effects on innate immunity and sickness responses.

Title Illuminated Paris, Essays on Art and Lighting in the Belle Époque Type Book Whole
Year 2019 Publication Abbreviated Journal
Volume Issue Pages
Keywords History; Society; Art
Abstract The City of Light. For many, these four words instantly conjure late nineteenth-century Paris and the garish colors of Toulouse-Lautrec’s iconic posters. More recently, the Eiffel Tower’s nightly show of sparkling electric lights has come to exemplify our fantasies of Parisian nightlife. Though we reflect longingly on such scenes, in Illuminated Paris, Hollis Clayson shows that there’s more to these clichés than meets the eye. In this richly illustrated book, she traces the dramatic evolution of lighting in Paris and how artists responded to the shifting visual and cultural scenes that resulted from these technologies. While older gas lighting produced a haze of orange, new electric lighting was hardly an improvement: the glare of experimental arc lights—themselves dangerous—left figures looking pale and ghoulish. As Clayson shows, artists’ representations of these new colors and shapes reveal turn-of-the-century concerns about modernization as electric lighting came to represent the harsh glare of rapidly accelerating social change. At the same time, in part thanks to American artists visiting the city, these works of art also produced our enduring romantic view of Parisian glamour and its Belle Époque.
