This study shows that high-intensity daylight exposure in the afternoon increases nighttime sleep intensity and reduces morning sleepiness without affecting circadian phase.

This study shows that calorie restriction induces daily torpor in mice, causing DNA damage that is repaired during arousal, and that cooling during arousal inhibits DNA repair.

The paper simulates coevolution of sleep/wake patterns in a predator/prey system, revealing cyclic temporal niche pursuit dynamics across evolutionary timescales.

The paper identifies stage-specific transcriptional changes in garden dormouse cerebral cortex during hibernation phases, revealing metabolic and redox adaptations and a reversal during arousal.

The paper develops methods to quantify ambient light for mammals using species-specific photoreceptor-based measurements, showing improved physiological prediction compared to lux.

The paper identifies a conserved cell-intrinsic signal inversion that enables the transition from nocturnality to diurnality, with mTOR signaling as a central mediator.

This study investigates how food scarcity and temperature affect photoperiodic responses in voles, revealing species-specific hypothalamic gene regulation of reproductive development.

This study examines how light affects alertness during a forced desynchrony protocol, finding that objective alertness improves with light regardless of time awake, while subjective effects depend on wake duration.

The paper compares photoperiodic responses in gonadal and somatic growth between two vole species, finding species-specific differences in sensitivity and developmental programming of the photoperiodic neuroendocrine system.
