Bones may look like the most stable part of the human body, but they are constantly being renewed, according to Annie Curtis, Associate Professor at the School of Pharmacy and Biomolecular Sciences.
Curtis said small groups of cells break down old bone tissue every day and build new bone in its place, a process known as remodeling.
Cells with their own clocks
Curtis said the cells responsible for this remodeling have their own biological clocks, similar to the internal rhythms that help regulate sleep, hunger and other daily bodily functions.
She noted that these daily rhythms tend to become less pronounced as people age.
