Clock Photoreceptor Shared By Plants and Animals
Article Abstract:
The light-absorbing molecule cryptochrome was first discovered in plants, but may also be a circadian photoreceptor for mice and fruit flies. Some researches say that the data from mice may indicate that cryptochrome is not a light sensor, but only part of the mouse clock mechanism. In any case, the research is significant because it demonstrates cross-species homologies in clock-related genes.

A Clock for the Ages
Article Abstract:
Cycles of rest, activity, sleep, and wakefulness are referred to as a circadian rhythm, and are usually genetically determined. Humans have been thought to be an exception to this rule, and a recent study seeks to address questions about the variability of human circadian rhythms and how they do or do not change with age.
