  Title The Dark Side of the Light: Rachel Carson, Light Pollution, and a Case for Federal Regulation Type Journal Article
  Year 2017 Publication Jurimetrics Abbreviated Journal Jurimetrics  
  Volume 57 Issue 4 Pages 505-528  
  Keywords Society; law; light pollution; regulation; environmentalism  
  Abstract This comment explores the negative effects of light pollution and considers whether current levels of artificial light at night (LAN) warrant federal control by the Environmental Protection Agency (EPA). This study first identifies the negative effects of light pollution on human health and the environment, treatment of which aligns with the mission statement of the EPA. Light pollution comprises both a private and a public nuisance. Next, this comment assesses the effectiveness of the common law approach, local government, state government, and federal control over light pollution in this context to determine which form of governance is most effective. Then, EPA involvement through federal and state implemented plans, as well as federal regulation of manufacturing is investigated. Last, this comment considers the necessity of private action through an emerging legal reform called new governance, which emphasizes public-private approaches. The negative effects of light pollution on human health and the environment could eventually lead the EPA to assert control over the regulation of light pollution, but under the current presidential administration this is highly unlikely. The predicted lack of government action leads me to call for nongovernment organizations (NGOs) to step in and take action to privately regulate light pollution and mitigate its negative effects through certification regimes, insurance premium incentives, and corporate social responsibility until government exerts regulatory control.

  Title Artificial Light at Night of Different Spectral Compositions Differentially Affects Tumor Growth in Mice: Interaction With Melatonin and Epigenetic Pathways Type Journal Article
  Year 2018 Publication Cancer Control : Journal of the Moffitt Cancer Center Abbreviated Journal Cancer Control  
  Volume 25 Issue 1 Pages 1073274818812908  
  Keywords Human Health; 6-Smt; Cfl; EE-halogen; GDM-levels; body mass; carbon; corticosterone; cosinor analysis; light at night; yellow-LED  
  Abstract Lighting technology is rapidly advancing toward shorter wavelength illuminations that offer energy-efficient properties. Along with this advantage, the increased use of such illuminations also poses some health challenges, particularly breast cancer progression. Here, we evaluated the effects of artificial light at night (ALAN) of 4 different spectral compositions (500-595 nm) at 350 Lux on melatonin suppression by measuring its urine metabolite 6-sulfatoxymelatonin, global DNA methylation, tumor growth, metastases formation, and urinary corticosterone levels in 4T1 breast cancer cell-inoculated female BALB/c mice. The results revealed an inverse dose-dependent relationship between wavelength and melatonin suppression. Short wavelength increased tumor growth, promoted lung metastases formation, and advanced DNA hypomethylation, while long wavelength lessened these effects. Melatonin treatment counteracted these effects and resulted in reduced cancer burden. The wavelength suppression threshold for melatonin-induced tumor growth was 500 nm. These results suggest that short wavelength increases cancer burden by inducing aberrant DNA methylation mediated by the suppression of melatonin. Additionally, melatonin suppression and global DNA methylation are suggested as promising biomarkers for early diagnosis and therapy of breast cancer. Finally, ALAN may manifest other physiological responses such as stress responses that may challenge the survival fitness of the animal under natural environments.

  Title Blue light exposure decreases systolic blood pressure, arterial stiffness, and improves endothelial function in humans Type Journal Article
  Year 2018 Publication European Journal of Preventive Cardiology Abbreviated Journal Eur J Prev Cardiol  
  Volume 25 Issue 17 Pages 1875-1883  
  Keywords Human Health; Blue light; blood pressure; endothelial function; forearm blood flow; pulse wave velocity  
  Abstract AIMS: Previous studies have shown that ultraviolet light can lead to the release of nitric oxide from the skin and decrease blood pressure. In contrast to visible light the local application of ultraviolet light bears a cancerogenic risk. Here, we investigated whether whole body exposure to visible blue light can also decrease blood pressure and increase endothelial function in healthy subjects. METHODS: In a randomised crossover study, 14 healthy male subjects were exposed on 2 days to monochromatic blue light or blue light with a filter foil (control light) over 30 minutes. We measured blood pressure (primary endpoint), heart rate, forearm vascular resistance, forearm blood flow, endothelial function (flow-mediated dilation), pulse wave velocity and plasma nitric oxide species, nitrite and nitroso compounds (secondary endpoints) during and up to 2 hours after exposure. RESULTS: Blue light exposure significantly decreased systolic blood pressure and increased heart rate as compared to control. In parallel, blue light significantly increased forearm blood flow, flow-mediated dilation, circulating nitric oxide species and nitroso compounds while it decreased forearm vascular resistance and pulse wave velocity. CONCLUSION: Whole body irradiation with visible blue light at real world doses improves blood pressure, endothelial function and arterial stiffness by nitric oxide released from photolabile intracutanous nitric oxide metabolites into circulating blood.

  Title Characterizing the zenithal night sky brightness in large territories: how many samples per square kilometre are needed? Type Journal Article
  Year 2017 Publication Monthly Notices of the Royal Astronomical Society Abbreviated Journal  
  Volume 473 Issue 3 Pages 4164-4173  
  Keywords Instrumentation; atmospheric effects; light pollution; numerical methods; photometry  
  Abstract A recurring question arises when trying to characterize, by means of measurements or theoretical calculations, the zenithal night sky brightness throughout a large territory: how many samples per square kilometre are needed? The optimum sampling distance should allow reconstructing, with sufficient accuracy, the continuous zenithal brightness map across the whole region, whilst at the same time avoiding unnecessary and redundant oversampling. This paper attempts to provide some tentative answers to this issue, using two complementary tools: the luminance structure function and the Nyquist–Shannon spatial sampling theorem. The analysis of several regions of the world, based on the data from the New world atlas of artificial night sky brightness, suggests that, as a rule of thumb, about one measurement per square kilometre could be sufficient for determining the zenithal night sky brightness of artificial origin at any point in a region to within ±0.1 magV arcsec–2 (in the root-mean-square sense) of its true value in the Johnson–Cousins V band. The exact reconstruction of the zenithal night sky brightness maps from samples taken at the Nyquist rate seems to be considerably more demanding.

  Title Light Pollution in the Galician Atlantic Islands Maritime-Terrestrial National Park 2018 Report Type Report
  Year 2018 Publication Abbreviated Journal  
  Volume Issue Pages  
  Keywords Conservation; Spain; Galicia; Europe; national park  
  Abstract The Galician Atlantic Islands Maritime-Terrestrial National Park (PNMTIAG), with the exception of the island of Cortegada, still has night skies of acceptable quality. However, the PNMTIAG islands are under strong photic pressures, both internal and external, that hinder the preservation of the basic features of the natural night, and call for an immediate action of all concerned stakeholders
