Title Predictions of melatonin suppression during the early biological night and their implications for residential light exposures prior to sleeping Type Journal Article
Year 2020 Publication Scientific Reports Abbreviated Journal Sci Rep
Volume 10 Issue 1 Pages 14114
Keywords Human Health
Abstract The magnitude of nocturnal melatonin suppression depends upon the spectrum, amount, and duration of light exposure. The functional relationship between melatonin suppression and the light spectrum and amount have been previously described. Only one duration-dependent parameter was needed to extend this functional relationship to predict nocturnal melatonin suppression during the early biological night from a variety of published studies. Those predictions suggest that ambient lighting commonly found in North American homes will not suppress melatonin for durations up to 3 h, whereas extended use of self-luminous displays in the home prior to sleep can.

Title [New lighting technology and our eyes] Type Journal Article
Year 2020 Publication Medecine Sciences : M/S Abbreviated Journal Med Sci (Paris)
Volume 36 Issue 8-9 Pages 769-773
Keywords Review; Human Health
Abstract The retina is the neurosensitive layer of the eye. In this tissue, photoreceptors convert light into nerve signals to be relayed to the brain. Despite retinal specialization in the treatment of light, excessive exposure can cause retinal damage, called retinal phototoxicity. In recent years, lighting devices rich in wavelengths of high energy (blue light) appeared, raising new concerns about retinal protection against light damage. We focus here on light-induced ocular diseases and the possible influence on visual health of new lighting technologies.

Dans la rétine, couche neurosensorielle de l’œil, les photorécepteurs transforment le signal lumineux en influx nerveux interprétable par le cerveau. Malgré sa spécialisation dans le traitement des signaux lumineux, la rétine peut subir des dommages, à la suite d’une exposition excessive à la lumière ; on parle alors de phototoxicité rétinienne. Ces dernières années, l’apparition de dispositifs d’éclairage riches en longueurs d’onde de forte énergie (ce que l’on nomme lumière bleue), remet le problème de la phototoxicité rétinienne à l’ordre du jour. Nous discutons des pathologies oculaires induites par la lumière et de la possible influence des nouvelles technologies d’éclairage sur notre santé visuelle.

Title Species-specific effects of moonlight on insectivorous bat activity in central Chile Type Journal Article
Year 2020 Publication Journal of Mammalogy Abbreviated Journal
Volume in press Issue Pages in press
Keywords Animals; Moonlight
Abstract Moonlight intensity influences the activity patterns of bats. Some bat species reduce their activity levels during brighter nights, a phenomenon known as “lunar phobia.” While lunar phobia of bats has been extensively studied in tropical regions, the same is not the case of bats in temperate regions. By using acoustic detectors, we examined differences in the activity of insectivorous bats on nights with different moonlight intensity in an agricultural landscape of central Chile. We also examined the hourly activity patterns throughout the night and how these varied between full and new moon nights. All bat species modified their activity based on the moonlight intensity; however, their effects were species-specific. The activity of Lasiurus varius, L. villosissimus, Myotis chiloensis, and Histiotus montanus was lower during bright nights, while Tadarida brasiliensis was the only species whose activity was higher during bright nights. Hourly activity throughout the night differed between full moon nights and new moon nights in most bat species. During full moon, bats concentrated their activities in the early hours of the nights; a more homogeneous activity pattern was exhibited during new moon night. Our study demonstrates that moonlight affects the activity of bats in Chile, a factor that should be considered when studying bats.

La intensidad de la luz de la luna influye sobre los patrones de actividad de los murciélagos. Algunas especies reducen sus niveles de actividad durante las noches más brillantes, un fenómeno conocido como “fobia lunar.” Si bien esos efectos se han estudiado ampliamente en las especies de murciélagos de las regiones tropicales, pocos estudios han evaluado la respuesta de los murciélagos en las regiones templadas. Mediante el uso de detectores acústicos, examinamos las diferencias en la actividad de los murciélagos insectívoros entre noches con diferentes intensidades de la luz de la luna en un paisaje agrícola de la zona central de Chile. También examinamos la actividad temporal a lo largo de la noche y cómo ésta varía entre noches de luna llena y luna nueva. Todas las especies de murciélagos modificaron su actividad en función de la intensidad de la luz de la luna; sin embargo, sus efectos fueron especie-específicos. La actividad de Lasiurus varius, Lasiurus villosissimus, Myotis chiloensis, e Histiotus montanus fue menor durante las noches más claras, mientras que Tadarida brasiliensis fue la única especie cuya actividad fue mayor en las noches claras. La actividad por hora a lo largo de la noche difirió entre las noches de luna llena y las de luna nueva en la mayoría de las especies de murciélagos. Durante la luna llena, los murciélagos concentraron su actividad durante las primeras horas de la noche, mostrando una actividad más homogénea a lo largo de la noche en luna nueva. Nuestro estudio indica que la luz de la luna es un factor que afecta la actividad de los murciélagos en Chile, y por lo tanto debe ser considerado al realizar estudios de murciélagos.

Title Analysis of Light Pollution in Ticino region during the period 2011-2016 Type Journal Article
Year 2020 Publication Sustainable Cities and Society Abbreviated Journal Sustainable Cities and Society
Volume 63 Issue Pages 102456
Keywords Skyglow
Abstract Since 2002, the Environmental Observatory of Southern Switzerland (OASI) has monitored a remarkable set of environmental parameters with the purpose of performing an enhanced observation of the regional environmental conditions. Since 2011, a campaign for the supervision of the artificial nighttime skyglow has been included in the OASI monitoring system exploiting the collaboration with DarkSky association. This network monitors the light pollution in several areas of Ticino, the southernmost Swiss Canton bordering Italy. It consists of multiple stations, which continuously measure the sky brightness. The University of Applied Sciences and Arts of Southern Switzerland, in collaboration with Politecnico di Milano, introduces the results of a study regarding the skyglow evolution during the period 2011-2016. The time-series of the OASI network were pre-processed to detect and discard data affected by natural perturbing events, such as moon and clouds presence and sun effect during twilights. In a second time, a distribution analysis of the data and an evaluation of the brightness trend during the considered period were performed. The results show that light pollution in Ticino is strictly influenced by the northern area of the nearby Italian Lombardy region and that during the surveyed years a decreasing of the pollution occurred.

Title The Possible Potentials of Astrotourism in Caucasus Type Journal Article
Year 2020 Publication Communications of the Byurakan Astrophysical Observatory Abbreviated Journal
Volume 67 Issue 1 Pages 127-132
Keywords Astrotourism
Abstract Astrotourism is not a new topic, but it is certainly a title that has been in the forefront of tourismand astronomy for less than two decades. For nearly half a century, observatories and sciencecenters have been opening their doors to the public on special occasions, such as Astronomy Day.However, for less than a decade, astrotourism has been the constant presence of tourists alongsideprofessional astronomers, especially on weekends. They have made it possible by following allthe principles. Until the early 1990s, one of the most important countries in the world to hostthe world's largest astronomical observatories was the Soviet Union. The Caucasus region in theformer Soviet Union hosted very important observatories due to its high altitudes, pure nature, andvery low amount of light pollution and, of course, the proper weather in warm seasons. Byurakanin Armenia, Abastumani in Georgia, Shamakhi in Azerbaijan, and BTA-6 in Russia are the fourmain collections left from that period. Fortunately, nearly two decades after the independenceof the countries in the region, the restoration and updating of these observatories have been onthe agenda. One of the helping arms to accelerate the revival of these observatories is to takeadvantage of the potential of astrotourism; especially with the location of these three countriesnear Iran, which has one of the largest astronomy enthusiast communities in the region.
