Summary: Artificial light at night (ALAN) is a global pollutant that disrupts circadian rhythmicity and physiological processes in animals. The sensitivity to ALAN varies among species, and there is a lack of information on its spatial extent of influence on bats. This study found that ALAN has a disturbance radius of at least 75 m for little brown bats and up to 25 m for big brown bats.

Summary: This study investigates the effects of artificial light at night (ALAN) on moth communities and finds that increased sky glow decreases moth abundance and species richness, and shifts community composition. The contrasting effects of local light sources and sky glow on moth community composition are important to understand the overall impacts of light pollution on biodiversity declines.

Summary: This study examines the individual-level and community-level effects of Artificial light at night (ALAN) on wildlife. The results show that ALAN affects prey pigmentation and mass, but selective predation by predators can mitigate the effects of ALAN on prey size. However, there were no cascading community-level effects on predation rates. This study highlights the importance of considering species-level distinctions and ecological complexity in understanding the impact of ALAN.

Summary: The study found that in marine environments, green and red ALAN have effects on marine primary producers, with green ALAN potentially increasing chlorophyll production and abundance in green microalgae, and red and green ALAN leading to changes in biomass and diversity of diatom assemblages.

Summary: Light pollution is a phenomenon caused by an increased concentration of light particles in the night-time environment due to human activity, resulting in the alteration of natural levels of darkness. It is profoundly changing night-time environmental conditions across the planet and its effects on life are being revealed by extensive research.

Summary: Artificial light at night (ALAN) has significant effects on plants, which in turn affect insect herbivory. However, these effects vary depending on the species and are influenced by forest types and light spectra. These findings highlight the complexity of considering ALAN in environmental management and planning.

Summary: Coral broadcast spawning events are crucial for coral reef maintenance and recovery, but artificial light at night disrupts the natural light:dark cycles that synchronize spawning. Analysis of a global dataset shows that light-polluted corals spawn closer to the full moon by 1-3 days compared to those in unlit reefs. This alters the timing of mass spawning, potentially reducing fertilization and survival rates, and hindering reef ecosystem resilience.

Summary: The global prevalence of broad spectrum lighting may disrupt visually guided ecological processes, especially in terms of prey camouflage at night. The conspicuousness of prey, particularly the yellow color morphs, is significantly increased by modern broad spectrum lighting technologies. These findings emphasize the importance of considering artificial light exposure in environmental management and planning.

Summary: We report an n-type In0.53Ga0.47As based Gunn light emitting diode operated at around 1.6 mu m. The device structure comprises of an n-type In0.53Ga0.47As epilayer with a thickness of 5 mu m grown by Metal Organic Vapour Phase Epitaxy (MOVPE) on a semi-insulating InP substrate and fabricated in a planar architecture with a stepped structure at anode side to suppress the destructive effect of high built-in electric field in propagating Gunn domain. Gunn diode is operated under pulsed voltage with a pulse width of 60 ns and pulse duration of 4.5 ns to keep the duty cycle as low as 0.0013%. The Gunn oscillations with an 1 ns period are observed at around 4.1 kV/ cm, which corresponds to the electric field threshold of Negative Differential Resistance (NDR). The light emission at around 1.6 mu m also starts at the threshold electric field of the NDR region (E = 4.2 kV/cm) of the current-voltage curve, and the emission intensity increases drastically with increasing applied electric field. The observed light emission at NDR threshold electric field where Gunn oscillations appear on the voltage pulse is attributed to the impact ionisation process occurring in the current domains along the sample, which generates excess carriers to initiate the band-to-band recombination in In0.53Ga0.47As.

Summary: The study found that light pollution has significant impacts on biodiversity, especially in non-urban habitats. The effects of Artificial Light At Night (ALAN) vary depending on landscape composition, emphasizing the importance of considering different environmental factors when studying its effects. Prioritizing efforts to reduce light pollution in non-urban habitats is crucial to mitigate its effects on biodiversity.

Summary: This study investigated the cytotoxic effects of LED and OLED light sources on stem cells, finding that the LED group induced higher apoptotic activity due to significant heat generation compared to OLED. Additionally, the LED group showed significant expression of intracellular reactive oxygen species, while increased cell proliferation was confirmed in the OLED group.

Summary: The study found that artificial light at night (ALAN) tends to advance the start date of the growing season (SOS) across the United States, although the overall response of SOS to ALAN was relatively weak compared with other potential factors. The phenological impact of ALAN showed a spatially divergent pattern, with different effects observed in climatically moderate, very cold, and hot regions within the United States.

Summary: We conducted a non-systematic review of epidemiological studies published since 2009 on the potential link between exposure to outdoor artificial light at night (O-ALAN) and disease occurrence in humans. After analyzing 51 identified studies, we found that while the majority of papers reported a link between O-ALAN exposure and various disorders, the strength of the evidence varied and several important factors were omitted. Therefore, further epidemiological studies that address these omissions are needed to establish a more conclusive association.
