Baker, R. R., & Sadovy, Y. (1978). The distance and nature of the light-trap response of moths. Nature, 276(5690), 818–821.
Abstract: LIGHT TRAPS of various forms have been used to collect and study moths for well over 100 yr, but surprisingly little is known about how they attract moths. There has been some evaluation of the factors influencing the size of light trap catches1–5 and of the mechanics of the terminal phase of the moth's approach to a light6, but virtually nothing is understood about the light-trap response itself. Such an understanding is perhaps unnecessary when light traps are used solely to collect specimens, but becomes crucial as soon as they are used for quantitative sampling or survey work7. Of particular importance to the interpretation of such work is a knowledge of the distance from which moths orientate with respect to a light source; it seems intuitively that this distance should be fairly large. We present here the results of three experiments designed to determine the distance of response of free-flying moths to an artificial light source. Our results support Sotthibandhu's claim4 that the effective range of a 125 W mercury vapour (MV) lamp is about 3 m. They also lead to speculation concerning the behavioural meaning of the light trap response in moths.

Abstract: Rapidly accumulating evidence indicates that light reduces the human pineal's inhibitory effect on the gonads. Artificially extended daily photoperiods, by allowing increased production of gonadal steroids, have probably accentuated the secular growth trend and may be causing males, especially adolescents and young adults, to have an overready hormonal response to situations which elicit aggressive behavior.

Abstract: The latitude of the equatorward auroral boundary near local midnight has been determined for 162 Defense Meteorological Satellite Program (DMSP) images in November‐December 1972. When grouped according to Kp and AE, these observations show approximate linear decreases in the average boundary latitude with increasing values of these magnetic indices. There appears also to be a slight diurnal variation in the boundary location. Mapping of the appropriate McIlwain injection boundaries to auroral latitudes shows good agreement with the average DMSP equatorward auroral boundary latitude. Similar analyses at 2000 and 2200 CGLT (corrected geomagnetic local time) using a different set of DMSP images yield similar results, with somewhat poorer agreement under quiet conditions.
