A genetic screen for mutants that alter circadian rhythms in Drosophila identified the first
clock gene—the period (per) gene. The per gene is a central player within a transcriptional …

Daily rhythms in behavior, physiology and metabolism are controlled by endogenous
circadian clocks. At the heart of these clocks is a circadian oscillator that keeps circadian …

Organisms ranging from bacteria to humans synchronize their internal clocks to daily cycles
of light and dark. Photic entrainment of the Drosophila clock is mediated by proteasomal …

Many animals use Earth's magnetic field (also known as the geomagnetic field) for
navigation. The favoured mechanism for magnetosensitivity involves a blue-light-activated …

The circadian clock of the honey bee is implicated in ecologically relevant complex
behaviors. These include time sensing, time-compensated sun-compass navigation, and …

The circadian clock plays a vital role in monarch butterfly (Danaus plexippus) migration by
providing the timing component of time-compensated sun compass orientation, a process …

Circadian clocks regulate daily fluctuations of many physiological and behavioral aspects in
life. They are synchronized with the environment via light or temperature cycles [1]. Natural …

Entrainment of the Drosophila circadian clock to light involves the light-induced degradation
of the clock protein timeless (TIM). We show here that this entrainment mechanism is …

Previous work in Drosophila has defined two populations of circadian brain neurons,
morning cells (M-cells) and evening cells (E-cells), both of which keep circadian time and …

This review deals with the biophysical aspects of flavin‐based photosensors, comprising
cryptochromes, LOV (Light, Oxygen and Voltage) and BLUF (Blue Light sensing Using FAD) …
