Scientists at EPFL report that a transient shape change in mitochondria—known as “pearling,” in which the organelle briefly forms bead-like constrictions—can redistribute clusters of mitochondrial DNA (mtDNA) into more evenly spaced nucleoids. The work, published April 2, 2026 in Science, suggests the process is triggered by calcium influx into mitochondria and may help explain how cells maintain robust mtDNA organization, a feature implicated in a range of mitochondrial-related disorders.
