Given that sleep deprivation studies consistently show that short sleep causes
neurocognitive deficits, the effects of insufficient sleep on brain health and cognition are of …

In this review, we discuss the remarkable potency and potential applications of a form of light
that is often overlooked in a circadian context: naturalistic levels of dim light at night (nLAN) …

In the absence of electric light, sleep for humans typically starts soon after dusk and at
higher latitudes daily sleep timing changes seasonally as photoperiod changes. However …

Many species synchronize reproductive behavior with a particular phase of the lunar cycle to
increase reproductive success. In humans, a lunar influence on reproductive behavior …

Artificial light at night (ALAN) has rapidly and drastically changed the global nocturnal
environment. Evidence for the effect of ALAN on animal behaviour is mounting and animals …

The moon's monthly cycle synchronizes reproduction in countless marine organisms. The
mass-spawning bristle worm Platynereis dumerilii uses an endogenous monthly oscillator …

The human sleep pattern is paradoxical. Sleep is vital for optimal physical and cognitive
performance, yet humans sleep the least of all primates. In addition, consolidated and …

Many organisms living along the coastlines synchronize their reproduction with the lunar
cycle. At the time of spring tide, thousands of grass puffers (Takifugu alboplumbeus) …

The human circadian system responds to light as low as 30 photopic lux. Furthermore,
recent evidence shows that there are huge individual differences in light sensitivity, which …

The giant honey bee Apis dorsata is unusual in being able to forage during both the day and
the night. To date, the extent of this unique nocturnal foraging behavior and the …
