Sleep deprivation in flies and mice leads to increased ROS (Reactive oxygen species) molecules in the gut. This is shown to be highly correalted to lethality. To show the causality, the over-expression of anti-oxiodants restores normal lifespan in the animals.

Drosophila kept in total darkness had "severe" long-term memory impairments compared to those exposed to normal light cycles. Scientists suggest that light promotes the release of neuropeptides related to long-term memory formation and argue light is "essential" for maintaining long-term memory.
