Abstract |
Most organisms display endogenously produced approximately ~24 h fluctuations in physiology and behavior, termed circadian rhythms. Circadian rhythms are driven by a transcriptional-translational feedback loop that is hierarchically expressed throughout the brain and body, with the suprachiasmatic nucleus of the hypothalamus serving as the master circadian oscillator at the top of the hierarchy. Appropriate circadian regulation is important for many homeostatic functions including energy regulation. Multiple genes involved in nutrient metabolism display rhythmic oscillations and metabolically related hormones such as glucagon, insulin, ghrelin, leptin, and corticosterone are released in a circadian fashion. Mice harboring mutations in circadian clock genes alter feeding behavior, endocrine signaling, and dietary fat absorption. Moreover, misalignment between behavioral and molecular circadian clocks can result in obesity in both rodents and humans. Importantly, circadian rhythms are most potently synchronized to the external environment by light information and exposure to light at night potentially disrupts circadian system function. Since the advent of electric lights around the turn of the 20th century, exposure to artificial and irregular light schedules has become commonplace. The increase in exposure to light at night parallels the global increase in the prevalence of obesity and metabolic disorders. In this review, we propose that exposure to light at night alters metabolic function through disruption of the circadian system. We first provide an introduction to the circadian system, with a specific emphasis on the effects of light on circadian rhythms. Next we address interactions between the circadian system and metabolism. Finally, we review current experimental and epidemiological work directly associating exposure to light at night and metabolism. |

Abstract |
This chapter examines the neglected practice of night photography, and how it critically addresses the environmental, sociohistorical, and urban issues in recent series by Christina Seely, Bruno Lessard, Michel Huneault, and Jeanine Michna-Bales. Drawing on Jacques Derrida, Emmanuel Levinas, and the emerging field of night studies to create a nocturnal philosophy—a dark photology—with which to frame the multifaceted issues at the heart of the series, the author examines the value that these photographic artists place upon night to document light pollution around the world, ongoing urban transformations in China, an environmental catastrophe and its aftermath in Québec, and the landscape of the Underground Railroad in the United States. These four series demonstrate how night photography offers a unique critical perspective on some of the most pressing problems of our age, and how these artists distance themselves from the predominantly diurnal register of documentary media. |
