Several years ago I spent some time in a lab studying sleep in fruit flies.

They've put out a number of interesting publications since my time there.

[1] Evidence of very large variability in sleep duration between flies, with limited consequences for very long duration sleep deprivation (wrt lethality)

[2] Evidence of context-dependent modulation of the effects of sleep deprivation. It appears the effects of sleep deprivation on males can be affected by sexual arousal/activity.

It makes me wonder if there are similar effects on humans. A night spent socialising too late does effect one differently to one spent working too late.
