NewsScientists discover the ‘ticking’ mechanism driving nature’s simplest circadian clock
Researchers have uncovered the molecular mechanism that drives the ’ticking’ of the circadian clock in cyanobacteria. A clock protein called KaiC controls chemical reactions with precision, acting like the hand of a clock that waits, then moves at just the right moment.

NewsResearch team traces evolutionary history of bacterial circadian clock on ancient Earth
To better understand the circadian clock in modern-day cyanobacteria, researchers studied ancient timekeeping systems. They examined the oscillation of the clock proteins in modern cyanobacteria, comparing it to the function of ancestral Kai proteins.

NewsResearchers uncover role of fungal circadian clock in pathogenicity
A new study reveals that the circadian clock plays a pivotal role in regulating Fusarium oxysporum’s response to zinc starvation—a core plant defense strategy—as well as in controlling secondary metabolism, thereby enhancing its virulence.

NewsCyanobacterial circadian clock uses an AM radio-like mechanism to control cellular processes
Cyanobacteria, an ancient lineage of bacteria that perform photosynthesis, have been found to regulate their genes using the same physics principle used in AM radio transmission.
