Mitochondria are known as the cell’s powerhouses, but new research shows they also guide cell movement. Using advanced imaging, this work reveals how mitochondria control direction and speed of migrating cells. Understanding this process may explain wound healing and how cancer cells spread throughout the body.

This research shows that the brain’s suprachiasmatic nucleus acts not only as a daily clock but also a seasonal energy switch. Studying hibernating ground squirrels reveals how neural activity shifts between high-energy summer states and ultra-efficient winter modes, with implications for metabolism, seasonal depression, and human hibernation.
