Title (up) Population-level study links short-wavelength nighttime illumination with breast cancer incidence in a major metropolitan area Type Journal Article
Year 2018 Publication Chronobiology International Abbreviated Journal Chronobiol Int
Volume 35 Issue 9 Pages 1198-1208
Keywords Human Health
Abstract Several population-level studies revealed a positive association between breast cancer (BC) incidence and artificial light at night (ALAN) exposure. However, the effect of short-wavelength illumination, implicated by laboratory research and small-scale cohort studies as the main driving force behind BC-ALAN association, has not been supported by any population-level study carried out to date. We investigated a possible link between BC and ALAN of different subspectra using a multi-spectral year-2011 satellite image, taken from the International Space Station, and superimposing it with year-2013 BC incidence data available for the Great Haifa Metropolitan Area in Israel. The analysis was performed using both ordinary least square (OLS) and spatial dependency models, controlling for socioeconomic and locational attributes of the study area. The study revealed strong associations between BC and blue and green light subspectra (B = 0.336 +/- 0.001 and B = 0.335 +/- 0.002, respectively; p < 0.01), compared to a somewhat weaker effect for the red subspectrum (B = 0.056 +/- 0.001; p < 0.01). However, spatial dependency models, controlling for spatial autocorrelation of regression residuals, confirmed only a positive association between BC incidence and short-wavelength (blue) ALAN subspectrum (z = 2.462, p < 0.05) while reporting insignificant associations between BC and either green (z = 1.425, p > 0.1) or red (z = -0.604, p > 0.1) subspectra. The obtained result is in line with the results of laboratory- and small-scale cohort studies linking short-wavelength nighttime illumination with circadian disruption and melatonin suppression. The detected effect of blue lights on BC incidence may help to develop informed illumination policies aimed at minimizing the adverse health effects of ALAN exposure on human health.

Title (up) Potentiality of Using Luojia 1-01 Nighttime Light Imagery to Investigate Artificial Light Pollution Type Journal Article
Year 2018 Publication Sensors Abbreviated Journal Sensors
Volume 18 Issue 9 Pages 2900
Keywords Remote Sensing; Instrumentation
Abstract The successful launch of Luojia 1-01 complements the existing nighttime light data with a high spatial resolution of 130 m. This paper is the first study to assess the potential of using Luojia 1-01 nighttime light imagery for investigating artificial light pollution. Eight Luojia 1-01 images were selected to conduct geometric correction. Then, the ability of Luojia 1-01 to detect artificial light pollution was assessed from three aspects, including the comparison between Luojia 1-01 and the Suomi National Polar-Orbiting Partnership Visible Infrared Imaging Radiometer Suite (NPP-VIIRS), the source of artificial light pollution and the patterns of urban light pollution. Moreover, the advantages and limitations of Luojia 1-01 were discussed. The results showed the following: (1) Luojia 1-01 can detect a higher dynamic range and capture the finer spatial details of artificial nighttime light. (2) The averages of the artificial light brightness were different between various land use types. The brightness of the artificial light pollution of airports, streets, and commercial services is high, while dark areas include farmland and rivers. (3) The light pollution patterns of four cities decreased away from the urban core and the total light pollution is highly related to the economic development. Our findings confirm that Luojia 1-01 can be effectively used to investigate artificial light pollution. Some limitations of Luojia 1-01, including its spectral range, radiometric calibration and the effects of clouds and moonlight, should be researched in future studies.

Title (up) Predation on cicadas by an Australian Flying-fox Pteropus poliocephalus based on DNA evidence Type Journal Article
Year 2018 Publication Australian Zoologist Abbreviated Journal Australian Zoologist
Volume in press Issue Pages
Keywords Animals
Abstract Historically, reports of insectivory in family Pteropodidae have largely been anecdotal and thought to be an incidental corollary of flying-foxes feeding on plant products. More recent direct observations of flying-foxes catching and consuming insects, as well as advances in techniques that increase our ability to detect dietary items, suggest that this behaviour may be deliberate and more common than previously thought. Usually, multiple insects are consumed, but it appears that flying-foxes hunt and eat them one at a time. However, we have collected and photographed oral ejecta pellets under trees with high flying-fox activity, some containing evidence of multiple masticated insects. Further genetic analysis proved that these pellets came from Grey-headed Flying-foxes Pteropus poliocephalus. We propose that flying-foxes use an array of insect feeding strategies, most likely in response to variation in insect abundance and activity, as well as abiotic factors such as light and temperature.

Title (up) Preventive Effect of Morning Bluish LED Light on Light-induced Melatonin Suppression at Night Type Journal Article
Year 2018 Publication Journal of Science and Technology in Lighting Abbreviated Journal
Volume 41 Issue Pages 206-210
Keywords Human Health
Abstract Bright nocturnal light has been known to suppress melatonin secretion. However, bright light exposure during daytime might reduce light-induced melatonin suppression (LIMS) at night. This study aims to evaluate the effect of high correlated color temperature LED light during daytime on LIMS. Male participants were exposed to different light conditions for 3 h in the morning (09:00â??12:00). The light conditions were dim light (<10 lx), 125 lx high correlated color temperature (CCT) LED light, and 250 lx high CCT LED light. The subjects were then exposed to bright light (white light, 300 lx) for 1.5 h at night (01:00â??02:30). Saliva samples were taken before (01:00) and after (02:30) exposure for evaluation of melatonin secretion. There were no significant differences in melatonin secretion before and after night-time light exposure on the 125 lx and 250 lx morning light conditions. Since these light intensities were almost equal to those in our previous study, the high CCT LED light might be appropriate for certain work places (e.g., hospitals and underground spaces), contributing to the reduction of our health risk and also saving energy.

Title (up) Principles for Studying and Managing Natural Quiet and Natural Darkness in National Parks and Other Protected Areas Type Journal Article
Year 2018 Publication The George Wright Forum Abbreviated Journal
Volume 35 Issue 3 Pages 350-362
Keywords Conservation; Planning; Regulation
Abstract A substantial body of research on natural quiet and natural darkness in national

parks, and protected areas more broadly, has been reported in the scientific and professional literature in recent years. However, this literature is widely scattered over many academic and professional journals that cover both the natural and social sciences. To help integrate and synthesize this body of work, we surveyed this diverse literature and collected representative examples in a book (Manning et al. 2018). We conclude our book with a series of principles

that we have distilled to help guide park managers to protect natural quiet and natural darkness. This paper presents those principles.

Much of our book focuses on national parks in the United States, and in the remainder of this paper the phrase “the national parks” refers to them. But we feel that the principles we have derived from our review of the scientific and professional literature on natural quiet and natural darkness apply equally well to a variety of parks and protected areas in the United States and elsewhere.

Natural quiet is generally defined as the sounds of nature uninterrupted by human-caused noise, and natural darkness is darkness unaffected by human-caused light. It is important to note that natural quiet and natural darkness do not necessarily mean absolute quiet or darkness, as the natural world often generates sounds of its own (e.g., birds calling, wind blowing,

rivers rushing) and has sources of illumination (e.g., the glow of celestial bodies and the fluorescence of some plants and animals).
