National Institutes of Natural Sciences Jun 13 2025 Researchers from the Institute for Molecular Science (IMS)/SOKENDAI and Kyushu University have uncovered the molecular mechanism that drives the "ticking" of the circadian clock in cyanobacteria. Their study reveals how a clock protein called KaiC controls chemical reactions with remarkable precision, acting like the hand of a clock that waits, then moves at just the right moment. The findings were published in PNAS Nexus on April 28, 2025. To
