Bioluminescence is the fascinating natural phenomenon by which living creatures produce
light. Bioluminescence occurs when the oxidation of a small-molecule luciferin is catalysed …

Life is a cyclical chemical process that is regulated in four dimensions. We distinguish parts
of the cycle: development describes the changes from single cell to adult, and aging the …

The circadian clock is required for adaptive responses to daily and seasonal changes in
environmental conditions,,. Light and the circadian clock interact to consolidate the phase of …

Regulation of circadian period in humans was thought to differ from that of other species,
with the period of the activity rhythm reported to range from 13 to 65 hours (median 25.2 …

BACKGROUND Global population growth, increased meat consumption, and concerns
about sustainability of resources are driving forces for future agriculture to produce higher …

Circadian clocks are believed to confer an advantage to plants, but the nature of that
advantage has been unknown. We show that a substantial photosynthetic advantage is …

In many organisms, the circadian clock is composed of functionally coupled morning and
evening oscillators. In Arabidopsis, oscillator coupling relies on a core loop in which the …

The interactive regulation between clock genes is central for oscillator function. Here, we
show interactions between the Arabidopsis clock genes LATE ELONGATED HYPOCOTYL …

The centrosome is the major microtubule-organizing centre of animal cells and through its
influence on the cytoskeleton is involved in cell shape, polarity and motility. It also has a …

The earth rotates on its axis every 24 h, with the result that any position on the earth's
surface alternately faces toward or away from the sun—day and night. That the metabolism …
