Fluorescent light is often used to create biological images, revealing the composition and functions of living cells. However, this type of light can negatively affect cells, sometimes causing them to detach from the substrate they are growing on. To study this phenomenon, scientists used microscope particles, which appear here as tiny points of light, to track how certain types of light exposure cause a physical relaxation of forces found in living cells.
