Circadian Rhythm News and Research

RSS

Circadian Rhythm is the regular recurrence, in cycles of about 24 hours, of biological processes or activities, such as sensitivity to drugs and stimuli, hormone secretion, sleeping, feeding, etc. This rhythm seems to be set by a 'biological clock' which seems to be set by recurring daylight and darkness.

Gut Bacteria Influence Stress Responses Through Circadian Rhythms

Understanding How Malaria Parasite Modulates Apicoplast Gene Expression

A recent study supported by Tokyo Tech’s World Research Hub Initiative discovered that gene expression within the apicoplast, an organelle in the malaria parasite Plasmodium falciparum, is controlled by melatonin (the circadian signaling hormone) in host blood and intrinsic parasite cues via a factor called ApSigma.
