Reported light in the sleep environment: enhancement of the sleep diary. [PDF]
, 2019 BackgroundLight is the primary synchronizing cue for the circadian timing system, capable of exerting robust physiological effects, even with very dim and/or brief photic exposure. Mammals, including humans, are particularly susceptible to light at night.

On light as an alerting stimulus at night
Acta Neurobiologiae Experimentalis, 2007 Light exposure at night increases alertness; however, it is not clear if light affects nocturnal alertness in the same way that it affects measures of circadian regulation. The purpose of this study was to determine if a previously established functional relationship between light and nocturnal melatonin suppression was the same as that relating light ...

Short-term variability of comet C/2012 S1 (ISON) at 4.8 AU from the Sun [PDF]
, 2015 We observed comet C/2012 S1 (ISON) during six nights in February 2013 when it was at 4.8 AU from the sun. At this distance and time the comet was not very active and it was theoretically possible to detect photometric variations likely due to the ...

Large‐scale human celebrations increase global light pollution
People and Nature, 2023 Culturally dependent human social behaviours involving artificial light usage can potentially affect light pollution patterns and thereby impact the night‐time ecology in populated areas, although to date this has not been examined globally. By analysing

Insect friendly light at night
Abstract Electric light at night poses a threat to both humans and ecosystems, compelling the search for an environmentally friendly lighting measure. Insects play a pivotal role in maintaining a healthy ecosystem and therefore we investigated the effects of different electric light sources on the attraction of insects after dusk. In this work,

Flatfish herding behavior in response to trawl sweeps: a comparison of diel responses to conventional sweeps and elevated sweeps [PDF]
, 2010 Commercial bottom trawls often have sweeps to herd fish into the net. Elevation of the sweeps off the seaf loor may reduce seafloor disturbance, but also reduce herding effectiveness.
