Time-lapse imaging can make complicated processes easier to grasp—think of a stitched-together sequence of photos that chronicles the construction of a building. A group of scientists, led by Sylvain Costes of the Biological Systems & Engineering Division, are using a similar approach to study how cells repair DNA damage. Their new time-lapse technique is already yielding insights into how cells repair DNA strand breaks, which is key to understanding how people respond to ionizing radiation. Scientists study DNA damage for a number of reasons, from learning how to protect astronauts from long-term exposure to cosmic rays to refining radiotherapy protocols that are designed to kill tumors.
