<jats:title>Mitochondrial Dynamics</jats:title> <jats:p> Mitochondria—the powerhouses of the cell—are autonomous organelles with their own genomes. Within cells, mitochondria are remarkably dynamic, continually moving around the cytoplasm and undergoing fusion and fission reactions. <jats:bold>Youle and van der Bliek</jats:bold> (p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" page="1062" related-article-type="in-this-issue" vol="337" xlink:href="10.1126/science.1219855">1062</jats:related-article> ) review the importance of mitochondrial fusion and fission in cellular responses to stress, interference with which are likely to play an important role in a variety of diseases including Parkinson's disease. In their Perspective, <jats:bold> <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6098" page="1052" related-article-type="in-this-issue" vol="337" xlink:href="10.1126/science.1224709"> <jats:bold>Hoppins and Nunnari</jats:bold> </jats:related-article> </jats:bold> explain that the endoplasmic reticulum is an active participant in mitochondrial division and discuss how mitochondrial dynamics and cell death are linked. </jats:p>
