WebOct 5, 2024 · A noninvasive method measures the viscosity in a cell nucleus by observing the movement and fusion of cellular components. Cell portraits. A pair of nucleoli (red) inside a cell nucleus (green) move toward fusion in this series of chronological images. By tracking this fusion over time, researchers can measure the viscosity inside the nucleus.
